This document provides a summary of the history and origins of HIV/AIDS. It discusses how SIV was transferred from chimpanzees and sooty mangabeys in Central Africa to humans between 1884-1924. The "bushmeat theory" suggests that hunting and butchering of primates led to repeated zoonotic transmissions of SIV. It then outlines the key conditions required for a zoonotic pathogen like SIV to establish itself in humans. The document proceeds to chronicle the major events in the identification and spread of HIV/AIDS globally from 1959-2006, including its emergence in the US in the early 1980s and the discovery of HIV in 1984.
Human papillomavirus (HPV) is a sexually transmitted virus that can cause genital warts and various cancers such as cervical cancer. There are over 100 types of HPV viruses, with some high-risk types being HPV-16, HPV-18 and HPV-31 that are linked to cervical cancer. While most HPV infections cause no symptoms and go away, persistent infections of high-risk HPV types can cause cancers like cervical cancer years later with HPV-
Strongyloides stercoralis, also known as the dwarf threadworm or military worm, is a parasitic roundworm that infects the small intestine. It was first discovered in the feces of French soldiers in 1876. The parasite has a direct life cycle within the human host and an optional free-living cycle in the environment. Transmission occurs through skin contact with filariform larvae in soil. Light infections may be asymptomatic, while heavier infections can cause gastrointestinal or pulmonary symptoms. Diagnosis involves examining stool samples under a microscope or using concentration techniques to find rhabditiform larvae.
1. Ascaris lumbricoides, commonly known as the large roundworm, infects humans through ingestion of its eggs from contaminated food, water, or soil.
2. The eggs hatch in the intestines, and the larvae migrate through the lungs before maturing into adult worms in the small intestine.
3. Symptoms range from mild to severe and include intestinal obstruction, pneumonia, and malnutrition. Diagnosis involves finding eggs in stool or adult worms after treatment. Prevention focuses on proper sanitation and hygiene.

Ascaris lumbricoides, also known as the giant intestinal roundworm, is a parasitic nematode that infects the small intestine of humans. It has a worldwide distribution, especially in tropical and subtropical areas with poor sanitation. The adult worms can reach lengths of 20-35 cm in females and 15-30 cm in males. The life cycle involves fertilized eggs passing in feces and developing into infective larvae outside the body. People become infected by ingesting these embryonated eggs. The larvae hatch in the intestine, penetrate the intestinal wall, migrate through the lungs, are swallowed and pass into the intestine where they mature into adult worms. Most infections are asymptomatic, but symptoms can include abdominal pain,

Epidemiology and control of helminth parasites.Tathagato Roy
Epidemiology is the study of disease distribution and patterns in populations. Helminths are parasitic worms that infect humans. The major helminth infections are caused by nematodes (roundworms), cestodes (tapeworms), and trematodes (flukes). Common helminth infections include ascariasis, hookworm infection, schistosomiasis, and cysticercosis. These infections are highly prevalent in tropical developing regions with poor sanitation. Chronic helminth infections can cause malnutrition, anemia, organ damage, and increased susceptibility to other diseases.
Typhoid fever is a systemic infection caused by the bacterium Salmonella typhi. It remains a global health issue, with millions of cases occurring annually where water and sanitation infrastructure is lacking. The disease is transmitted through ingestion of contaminated food or water. Clinical features include sustained fever, headache, abdominal pain, and rose colored spots on the abdomen. Definitive diagnosis requires isolating S. typhi from blood or bone marrow cultures. Treatment aims to control cases and carriers to limit further spread, through antibiotic therapy, immunization, and improving sanitation and access to clean water.
Enterobius vermicularis, also known as the pinworm or threadworm, is a common intestinal parasite in humans. It has a worldwide distribution. The female pinworm is 8-13 mm long and lives in the colon, where it lays eggs. The eggs can cause itching when they are deposited around the anus by the female at night. Infection occurs through ingestion of pinworm eggs. Proper hygiene practices can help prevent the spread of pinworm infection.
Arboviruses are viruses that can be transmitted to humans by arthropod vectors such as mosquitoes and ticks. There are approximately 80 known arboviruses that cause human disease. They are classified into families including Togaviridae, Flaviviridae, Bunyaviridae, Reoviridae, and Rhabdoviridae. Some important arboviruses prevalent in India include Chikungunya virus, Dengue virus, Japanese encephalitis virus, Kyasanur forest disease virus, and Sindbis virus. These viruses are transmitted between vertebrate hosts and arthropod vectors in natural cycles and can cause diseases ranging from fever and rash to hemorrhagic

Wuchereria bancrofti is a parasitic nematode that causes lymphatic filariasis (elephantiasis) in humans. It is transmitted by mosquitoes and lives in the human lymphatic system. The parasite has a complex life cycle involving microfilariae in human blood that are ingested by mosquitoes during feeding. The mosquito serves as an intermediate host where the microfilariae develop into infective larvae, which are then transmitted to humans during subsequent blood feeding, developing into adult worms in the lymphatics. Clinical manifestations range from asymptomatic microfilaremia to lymphedema and elephantiasis of the legs and genitals due to long-term infection and damage.
Hookworm is a parasitic roundworm that infects the small intestine. There are two main species that infect humans: Ancylostoma duodenale and Necator americanus. They are found primarily in tropical and subtropical regions. The worms attach to the intestinal wall and suck blood, causing iron deficiency anemia. Symptoms include fatigue, abdominal pain, and bloody stools. Diagnosis is made by finding hookworm eggs in stool samples. Treatment involves deworming medications like mebendazole or albendazole. Prevention focuses on proper sanitation and hygiene to avoid skin penetration and soil contamination with infected feces.
HIV stands for human immunodeficiency virus. AIDS stands for acquired immunodeficiency syndrome. Scientists believe HIV originated from chimpanzees in West Africa and was transmitted to humans through contact with their infected blood. The three most common ways HIV is spread are through unprotected sex, sharing needles, and from mother to child during pregnancy or breastfeeding. Less common ways include occupational needle sticks or transplants involving infected blood. Three ways to prevent spread are getting tested and treated if positive, using condoms correctly, and not sharing needles for drug use.

Hepatitis And Hiv Co Infection Tonia Poteat 060508elfaye
A presentation by Tonia Poteat from the CDC Global AIDS Project on the topic of Hepatitis B & C and HIV Co-infection. This webcast was presented live to ECHO (Evaluation Center for HIV and Oral Health) grantees on June 5, 2008.
This document provides a historical timeline of key events in the HIV/AIDS epidemic from the 1970s-2002 based on information collected by Dr. MZ. It describes the initial cases identified in the late 1970s, the naming and early reports of AIDS in 1981, the identification of HIV as the cause in 1983-1984, and major developments in treatment, awareness, and global response through the 1990s and early 2000s.
The natural history of HIV/AIDS refers to the progression of the disease from initial exposure to recovery or death. HIV evolved from simian immunodeficiency viruses that crossed species from chimpanzees and sooty mangabeys into humans. HIV was first discovered in 1981 when cases of Pneumocystis pneumonia and Kaposi's sarcoma in gay men were reported. HIV infects and destroys CD4+ T cells, gradually weakening the immune system. If untreated, HIV develops into AIDS, defined by a CD4 count below 200 or the presence of an AIDS-defining illness. The clinical course varies but typically involves acute infection, asymptomatic latency, and late stage AIDS without treatment over 7-10 years.

A Digital Eurovision for European UnionRene Summer
A Digital Eurovision for the European Union – the next step for European Public Service Broadcasting without frontiers. Why and how we must increase the availability of public service broadcasting to the widest Pan-European use.
This paper aims to initiate a discussion in Europe about the future of mass media in relation to the possibilities that can be achieved through technological development and policy innovation to stimulate the rise of a Pan-European identity across the European Union. By classifying current affairs reporting (news, current affairs and documentaries) produced by/for public service broadcasters (PSB) to fall within the definition of Open Government Data, European policy makers will unlock access to a wealth of European PSB content for European citizens, journalists and new start-ups to access, interact with, aggregate and disseminate. Such policy innovation not only comes with the already acknowledged economic benefits associated with open data and data-driven innovation; it also helps stimulate the creation of a strong Pan-European identity through increased Pan-European access to national stories, news and identity projections.

Kerala needs not new malls,mosques,churches and templesDr. Raju M. Mathew
Kerala is facing environmental issues like pollution of water sources and accumulation of garbage due to religious events, political rallies, and unplanned development. The document proposes that religious organizations, political parties, and businesses invest in solar energy, sewage treatment, and water purification plants instead of new buildings. A social accountability act is needed to ensure compensation is paid for environmental damage and the well-being of citizens is prioritized over temples, malls or political activities.
Power point presentation -The History of HIV/AIDSSol Velazquez
The document summarizes the history and origins of HIV/AIDS, beginning with the first reported cases in 1981 among homosexual men in the US. It describes the identification of the virus (HIV) in 1983 and its links to similar viruses found in African primates like chimpanzees (SIV). Theories suggest the virus crossed over to humans through activities like bushmeat hunting and processing or vaccine production in Africa in the early 20th century. By the 1980s HIV/AIDS had spread globally and become a major epidemic affecting millions of people.
Co relation of csf and neurological findings in hiv positive patientsRahul Nirmale
This document provides a literature review on neurological manifestations in HIV positive patients and the correlation with cerebrospinal fluid (CSF) parameters. It summarizes several studies that examined the prevalence and nature of neurological disorders in HIV patients and their relationship to CD4 count and other CSF markers. Many studies found neurological problems to be common and correlated with immunosuppression. Cryptococcal meningitis was a frequent opportunistic infection. Accurately diagnosing neurological conditions is important for treatment, and CSF analysis continues to be useful for this despite modern imaging technologies.
The document discusses the origin of HIV and AIDS. It explains that HIV is closely related to viruses found in chimpanzees (HIV-1) and sooty mangabeys (HIV-2) in West Africa. The leading theory is that the viruses crossed into humans in the early 20th century when humans hunted and butchered chimpanzees and monkeys for meat. The earliest known case of HIV in a human was identified in 1959 in the Democratic Republic of Congo. By the 1980s, HIV had spread globally and was recognized as the cause of AIDS.
Reading Guide—The Puzzling Origins of AIDS” by Jim Moore .docxsodhi3
Reading Guide—“The Puzzling Origins of AIDS” by Jim Moore
Subheading—The title tells us the article is about the origins of AIDS and the subheading tells us
that Moore will present 4 rival theories (hypotheses, arguments) and that there are important
lessons to be learned from each.
¶1-2: These paragraphs summarize some key history about HIV, the two main strains of HIV in
humans, and the non-human primate viruses that gave rise to the human virus. Given the genetics,
there have been multiple transmission events of versions of SIV to humans that ultimately evolved
into forms of HIV.
¶3: The question. Here we get the main question that Moore will address in the article. The
question is explicitly stated and repeated.
¶4: Setting up the context for the discussion, how Moore became involved in it, and how we should
look at the competing answers.
Theory 1: Tainted Polio Vaccine
¶5-7: Lay out the basics for the hypothesis that tainted polio vaccine is responsible for the
emergence of HIV. Pay close attention to what primate species are discussed, how polio vaccine was
developed, and the geography Moore discusses.
¶8-14: This is where Moore refutes Theory 1. He spends a lot of time discussing specific evidence
that invalidates the key claims of this theory. Pay close attention to how he sets it up.
Theory 2: Cut Hunter
¶15: Lays out the basic elements of the argument. Pay close attention to this theory because it
forms the basis for theories 3 and 4.
¶16: This isn’t so much a rebuttal of the argument but highlighting the challenges to testing this
particular theory. Because it is general, because it is not limited in time or space, it cannot account
for why the AIDS epidemic emerged when it did and it makes it very hard to test this hypothesis,
which, as Moore points out, “A hypothesis that does not account for the timing of the AIDS epidemic
and that is not falsifiable is of limited use.”
Theory 3: Contaminated Needles
¶17-19: This theory builds on cut hunter, providing a more specific timing for transmission events
and a mechanism for how HIV, once it emerged from initial transmission and evolution, could have
been passed relatively quickly through populations. The advent of disposable syringes is key and te
timing of that plays a role in why this theory may not be the best explanation. Based on the genetics,
HIV emerged earlier than disposable syringes.
Theory 4: Heart of Darkness
¶20-26: This is the theory that Moore developed with two of his students. It builds on cut hunter,
providing a specific context for the basic cut hunter hypothesis to give rise to the AIDS epidemic
and incorporates contaminated syringes but does not rely on disposable syringes. For Moore, the
context of exploitation and degradation of French and Belgian colonial policies in central Africa
provide the necessary context to situate the general cut hunter theory effectively with the timing of
th ...
The document discusses the history and epidemiology of HIV. It describes how HIV is transmitted through sexual intercourse, blood transfusions, needle sharing, and from mother to child. Landmark events in HIV management included the identification of HIV in the 1980s and the introduction of HAART therapy in 1996, which drastically reduced mortality rates in western countries. Globally in 2017, there were 36.9 million people living with HIV, with the highest rates of transmission being receptive anal intercourse. In the Philippines, HIV rates continue to rise and regions 4A, 3, and NCR have the highest rates of new cases.

This document discusses emerging and re-emerging infectious diseases. It begins by quoting Girolamo Frascatoro who spoke about syphilis in the 15th century, noting diseases will reoccur. Microbes evolve faster than humans. Infectious diseases have significantly impacted history, like the Black Plague. Emerging diseases are new, while re-emerging were previously controlled but increasing. Factors contributing to emergence include microbial adaptation, human behavior, and environmental changes. Examples discussed are MERS, Ebola, SARS, avian influenza, Zika virus, and potential bioterrorism agents. Preventing emergence requires surveillance, research, infrastructure, training, and prevention/control strategies.
HIV AND AIDS is the most critical disease in the world.
Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV).At the end of 2015, 17.0 million people were receiving ART worldwide; this represents 46% (43–50%) of the 36.7 million (34.0–39.8 million) people living with HIV.
HIV/AIDS remains one of the world's most significant public health challenges, particularly in low- and middle-income countries.There is no functional cure for HIV or AIDS, meaning that there is no procedure or medication which has been scientifically proven to reliably eliminate the virus from a person's body or reverse the damage to the immune system.
The document discusses HIV/AIDS, including that HIV attacks the immune system, weakening it and allowing for life-threatening infections and diseases like AIDS. It was first identified in 1981 in the U.S. among homosexual men. No cure exists, but antiretroviral therapy can suppress the virus. HIV is transmitted via blood and certain bodily fluids, but not through casual contact. The global pandemic has caused tens of millions of infections and deaths since the early 1980s.
This document summarizes Stephen Higgs' presentation to the 6th KEMRI Annual Scientific and Health Conference in Nairobi, Kenya on February 9, 2016. It provides background on the American Society of Tropical Medicine and Hygiene (ASTMH), tracing its origins and evolution from 1903 to present day. Key details include its founding in response to yellow fever epidemics, early members like William Gorgas and Carlos Finlay, its role in malaria and yellow fever research, and its current status as the largest scientific organization dedicated to tropical medicine and global health.
HIV causes AIDS by attacking CD4 cells of the immune system. It enters cells through binding to CD4 and CXCR4/CCR5 receptors, integrating its RNA into the cell's DNA. This leads to increased viral load and decreased CD4 count over many years until opportunistic infections define AIDS. Globally, HIV has infected over 75 million people and claimed over 32 million lives since the early 1980s.
Rene Sabatier noticed unusual symptoms in healthy young homosexual men and realized their bodies were invaded by a new virus. This led to the isolation of HIV in the 1980s. HIV causes AIDS by attacking CD4 cells and weakening the immune system. It is transmitted through sexual contact, blood transfusions, needle sharing, and from mother to child. While there is no cure for AIDS, education programs aim to prevent transmission through promoting safe sex practices and blood safety.

HIV originated from chimpanzees in Central Africa, likely jumping to humans in the late 1800s when humans hunted chimpanzees for meat. It slowly spread across Africa and later worldwide. The earliest known case was detected in 1959 in what is now the Democratic Republic of Congo. By the 1980s, AIDS was recognized as a global epidemic affecting millions of people. There is no cure for HIV/AIDS, but treatment can control the virus.
This document summarizes a seminar presentation on Ebola virus disease (EVD). It provides an overview of EVD outbreaks, case definitions, epidemiology, clinical presentation, diagnosis, treatment, and control/prevention. Key points include: EVD is caused by infection with Ebola virus and transmitted through contact with infected body fluids; symptoms range from fever and fatigue to vomiting and hemorrhaging; diagnosis involves virus detection through antigen/antibody tests or PCR; treatment is supportive care as no vaccine currently exists; control relies on isolation, contact tracing, and barrier precautions.

epidemiology report on The Coming Plague by Laurie GarrettJames Nichols
This book review summarizes Laurie Garrett's book "The Coming Plague", which chronicles the efforts of the CDC and other agencies to investigate and contain emerging pathogens since World War II. The book details epidemiological investigations of diseases such as Bolivian hemorrhagic fever, Ebola, yellow fever, and more. It demonstrates how epidemiology is applied in real world disease outbreaks and the challenges investigators face. The book also examines the successful eradication of smallpox and efforts to eliminate polio and malaria.
The document provides information about various parasites including:
1. The Ampulex compressa wasp that paralyzes cockroaches and turns them into "zombies" to protect its eggs.
2. The Myrmeconema neotropicum parasite that lives in ant abdomens and causes them to display red butts, attracting birds to spread the parasite.
3. The candiru fish that can infect human urethras and stories of extraction.
4. The history of hookworm discovery and potential use for treating allergies.
5. Toxoplasma gondii mind control of rats to be attracted to cats and spread to their intestines where
The document provides instructions for students to complete various classroom activities related to evolution, including a Venn diagram comparing mitosis and meiosis, defining science, completing surveys on the nature of science and evolution, modeling natural selection through an activity, and taking notes on key concepts like natural selection, fitness, and evidence for evolution such as homologous structures.
Mitosis and meiosis are two types of cell division. Mitosis produces two identical daughter cells and is used for growth and repair of the body. Meiosis produces gametes like sperm and egg cells and involves two cell divisions. The first division separates homologous chromosomes, while the second separates sister chromatids, resulting in four haploid cells. Meiosis introduces genetic variation through independent assortment and crossing over during prophase I.
Gregor Mendel first explained genetic inheritance in 1866 through experiments with pea plants. He discovered that genetic traits are passed from parents to offspring through discrete units called genes located on DNA. Genes for different traits are usually passed on independently of each other based on the laws of segregation and independent assortment. Understanding genetics helps explain inheritance of traits and diseases and evolution.
The document provides guidance on writing an introduction to research. It recommends including background on the topic, its importance, and the common methods used. It also offers tips on in-text citations, using scientific names, stating the hypothesis, and keeping track of sources. Logistics are discussed, such as making the introduction 1-2 double-spaced pages.
Proteins are made of amino acids and their structure and function are determined by their sequence and folding. There are four levels of protein structure: primary, secondary, tertiary, and quaternary. Enzymes are proteins that catalyze biochemical reactions and examples include hydrolases and lactase. The structure and function of enzymes can be affected by factors like temperature, pH, and inhibitors. An enzyme lab extracts the enzyme tyrosinase from mushrooms to test its reaction rate under normal and altered conditions and compare results.

The structure and function of enzymes can be affected by factors like temperature, pH, and inhibitors. An enzyme lab was described that extracts the enzyme tyrosinase from mushrooms to test its reaction rate under normal and altered conditions.
Mutations are changes in the genetic material of a cell that can result in changes to proteins. There are three main types of point mutations: silent mutations which do not change the protein, missense mutations which change one amino acid in the protein, and nonsense mutations which result in a premature stop in translation. Frameshift mutations occur when nucleotides are inserted or deleted, changing the reading frame and resulting in a completely different protein sequence with no stop codon. Mutations can occur during DNA replication due to errors or exposure to mutagens like UV light, chemicals, or intercalating dyes.
The document summarizes an experiment to test the reaction rate of the enzyme tyrosinase under different conditions. Tyrosinase is extracted from portobello mushrooms and its reaction with L-DOPA is tested under normal conditions and compared to when exposed to inhibitors, increased temperature, or changes in pH. The experiment involves extracting the enzyme, performing a control reaction, and then experimental reactions under different pH levels, inhibitors, or temperatures to see how these factors affect the reaction rate of tyrosinase.
The documents describe how cells control which genes are turned on or off through gene regulation, allowing different cells to express specific proteins for their functions. A key example is the lac operon in prokaryotes, which regulates genes to digest lactose by turning them on only when lactose is present. Gene regulation in eukaryotes is more complex, controlling transcription, RNA processing, translation and protein modification to regulate gene expression.
The document provides instructions for purifying fluorescent proteins expressed in E. coli, including breaking open the cells, separating cell debris via centrifugation, and using nickel beads and column chromatography to isolate the fluorescent proteins from other proteins in the supernatant. Key steps involve lysing the cells with lysozyme, binding the fluorescent proteins to nickel beads via their histidine tags, and eluting the purified proteins from the column using imidazole buffer.
The document summarizes the process of transforming E. coli bacteria to produce fluorescent proteins. It will be done by inserting a plasmid containing a gene for a fluorescent protein into E. coli. The plasmid also contains an antibiotic resistance gene so that transformed bacteria can be selected by growing them in media containing antibiotics. The foreign DNA from the plasmid will be transcribed and translated within the bacterial cells, causing them to produce and glow with the fluorescent protein. This demonstrates how altering an organism's genotype through molecular biology techniques can change its phenotype.
Translation is the process by which the genetic code contained within mRNA is used to synthesize proteins. During translation, mRNA is decoded by ribosomes to produce an amino acid chain. Key molecules involved in translation include mRNA, which contains the code to be translated; tRNA, which carries the correct amino acid to the ribosome; and ribosomes, which assemble proteins by linking amino acids in the proper order specified by the mRNA. Translation occurs in both eukaryotes and prokaryotes.
The document provides instructions for a DNA replication activity involving student teams competing to make copies of DNA strands using the fewest nucleotides. The objective is for each team to end up with two DNA strands taped to the whiteboard. Rules prohibit talking during the activity and allow two minutes for strategy discussion beforehand. The activity aims to demonstrate the speed of DNA replication in human versus bacterial cells.
Central dogma and transcription slidesQuanina Quan
The document discusses the central dogma of molecular biology and transcription, specifically describing the process of transcription which involves DNA being used as a template to produce a complementary RNA copy. It explains transcription occurs differently in eukaryotes versus prokaryotes, with the main steps being initiation, elongation, and termination for both, though eukaryotes have additional post-transcriptional modification steps.

This document contains questions and answers related to biology topics like osmosis, cells, cell respiration, photosynthesis, and general biology concepts. The questions range from $100 to $500 in value and cover definitions, processes, equations, and molecular structures. The final jeopardy question involves drawing the bonding of two amino acids and listing the general formula for monosaccharides.
Photosynthesis converts light energy to chemical energy in the form of sugars. It occurs in plants, algae, and other organisms through two main stages - the light reaction and Calvin cycle. The light reaction uses energy from sunlight to make ATP and NADPH in the chloroplast thylakoid membrane. The Calvin cycle then uses ATP and NADPH to incorporate carbon dioxide from the air into organic carbon compounds to make sugars. Understanding photosynthesis can help reduce carbon dioxide levels through applications like using plants to capture carbon.
Cellular respiration is a process that uses sugar to produce ATP through a series of steps. It occurs in the mitochondria of cells and involves glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis breaks down glucose in the cytoplasm to produce ATP and NADH. The citric acid cycle and oxidative phosphorylation use the products of glycolysis to generate more ATP. Fermentation occurs when cells do not receive enough oxygen, producing either lactic acid or alcohol as a byproduct.
Fexofenadine is sold under the brand name Allegra.
It is a selective peripheral H1 blocker. It is classified as a second-generation antihistamine because it is less able to pass the blood–brain barrier and causes lesser sedation, as compared to first-generation antihistamines.
It is on the World Health Organization's List of Essential Medicines. Fexofenadine has been manufactured in generic form since 2011.
Allopurinol, a uric acid synthesis inhibitor acts by inhibiting Xanthine oxidase competitively as well as non- competitively, Whereas Oxypurinol is a non-competitive inhibitor of xanthine oxidase.
Part III - Cumulative Grief: Learning how to honor the many losses that occur...bkling
Cumulative grief, also known as compounded grief, is grief that occurs more than once in a brief period of time. As a person with cancer, a caregiver or professional in this world, we are often met with confronting grief on a frequent basis. Learn about cumulative grief and ways to cope with it. We will also explore methods to heal from this challenging experience.
Congestive Heart failure is caused by low cardiac output and high sympathetic discharge. Diuretics reduce preload, ACE inhibitors lower afterload, beta blockers reduce sympathetic activity, and digitalis has inotropic effects. Newer medications target vasodilation and myosin activation to improve heart efficiency while lowering energy requirements. Combination therapy, following an assessment of cardiac function and volume status, is the most effective strategy to heart failure care.
Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) CosmeticsMuskanShingari
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.
Breast cancer :Receptor (ER/PR/HER2 NEU) Discordance.pptxDr. Sumit KUMAR
Receptor Discordance in Breast Carcinoma During the Course of Life
Definition:
Receptor discordance refers to changes in the status of hormone receptors (estrogen receptor ERα, progesterone receptor PgR, and HER2) in breast cancer tumors over time or between primary and metastatic sites.
Causes:
Tumor Evolution:
Genetic and epigenetic changes during tumor progression can lead to alterations in receptor status.
Treatment Effects:
Therapies, especially endocrine and targeted therapies, can selectively pressure tumor cells, causing shifts in receptor expression.
Heterogeneity:
Inherent heterogeneity within the tumor can result in subpopulations of cells with different receptor statuses.
Impact on Treatment:
Therapeutic Resistance:
Loss of ERα or PgR can lead to resistance to endocrine therapies.
HER2 discordance affects the efficacy of HER2-targeted treatments.
Treatment Adjustment:
Regular reassessment of receptor status may be necessary to adjust treatment strategies appropriately.
Clinical Implications:
Prognosis:
Receptor discordance is often associated with a poorer prognosis.
Biopsies:
Obtaining biopsies from metastatic sites is crucial for accurate receptor status assessment and effective treatment planning.
Monitoring:
Continuous monitoring of receptor status throughout the disease course can guide personalized therapy adjustments.
Understanding and managing receptor discordance is essential for optimizing treatment outcomes and improving the prognosis for breast cancer patients.
The Children are very vulnerable to get affected with respiratory disease.
In our country, the respiratory Disease conditions are consider as major cause for mortality and Morbidity in Child.

where bushmeat is practiced, and 17.1% in the most exposed people of
these villages.
5. HIV History
Zoonosis (transfer of a pathogen from non-human animals to humans) and subsequent
spread of the pathogen between humans, requires the following conditions:
1. a human population;
2. a nearby population of a host animal;
3. an infectious pathogen in the host animal that can spread from animal to human;
4. Interaction between the species to transmit enough of the pathogen to humans to
establish a human foothold, which could have taken millions of individual exposures;
5. Ability of the pathogen to spread from human to human (perhaps acquired by mutation);
6. Some process allowing the pathogen to disperse widely, preventing the infection from
"burning out" by either killing off its human hosts or provoking immunity in a local
population of humans.
