The endocrine system is made up of glands that produce hormones and release them into the bloodstream to regulate various bodily functions. The major glands include the hypothalamus, pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries, and testes. Hormones control functions such as metabolism, growth, sexual development, reproduction, and the stress response. Imbalances in hormone levels can cause disorders that must be treated by controlling hormone production.
The document summarizes the key endocrine glands and their hormones. It discusses that the endocrine system consists of ductless glands that secrete hormones which regulate various bodily functions. The pituitary gland is called the "master gland" as it controls the secretion of hormones from other endocrine glands through negative feedback mechanisms. The major endocrine glands discussed are the pituitary, thyroid, parathyroid, adrenal, ovaries, testes, pineal and pancreas. Each gland and its hormones are listed along with their functions in the human body.
The document discusses several endocrine glands and their functions. It describes that the hypothalamus and pituitary gland control many other endocrine glands. The pituitary gland secretes hormones that affect the thyroid, reproductive organs, and adrenal glands. Other glands discussed include the thyroid, parathyroid, pancreas, adrenal glands, testes and ovaries. Each gland produces specific hormones that regulate important body processes and functions.
Hormones are chemical messengers that are secreted from glands into the bloodstream and affect cells in other parts of the body. There are three main types of chemical signals used for cell-to-cell communication: peptide hormones, steroid hormones, and amino acid-derived hormones. Peptide hormones bind to receptor proteins in the cell membrane and use secondary messengers to initiate a cellular response, while steroid hormones enter cells and directly stimulate gene transcription, leading to a slower response. The endocrine system utilizes hormones to help regulate and coordinate important bodily functions and processes such as growth, development, metabolism, and homeostasis.
This document provides an overview of the endocrine system and hormones. It discusses the discovery of hormones in 1902 by Bayliss and Starling. It defines hormones and describes the principal functions of the endocrine system in maintaining homeostasis, growth, development, and reproduction. It compares the endocrine and nervous systems and describes different types of cell signaling. It provides details on the major endocrine glands and hormones, hormone classification, mechanisms of hormone action, and feedback control of hormone secretion.
The endocrine system controls many bodily processes through glands that produce hormones. The pituitary gland hangs from the hypothalamus and controls other glands. The pineal gland regulates circadian rhythms through melatonin. The thyroid gland regulates metabolism and growth through thyroxine and calcitonin. The parathyroid glands control calcium levels in blood. The thymus forms parts of the immune system through T cell production. The adrenal glands prepare the body for stress through hormones like adrenaline. The pancreas regulates blood sugar levels through insulin and glucagon from the pancreatic islets. The gonads, testes and ovaries, produce sex hormones like testosterone and estrogen.
The endocrine system helps regulate body activities through hormones. The hypothalamus and pituitary gland control other endocrine glands like the thyroid, parathyroid, adrenals, pancreas, gonads, thymus and pineal gland.

The pituitary gland controls the functions of other endocrine glands like the thyroid, which regulates metabolism, and the adrenals, which help the body deal with stress. Feedback mechanisms help regulate hormone levels to maintain homeostasis.
The hypothalamus produces hormones that control the anterior pituitary gland's production of hormones. The posterior pituitary secretes hormones produced in the hypothalamus. The pineal gland releases melatonin to control circadian rhythms. The thyroid produces hormones like thyroxine and triiodothyronine that control metabolism. The parathyroids regulate calcium levels through parathormone. The adrenal cortex releases steroid hormones like cortisol and aldosterone that help the body respond to stress.

Endocrine System (Hormones in Animals/WBBSE))RanjanShaw5
ENDOCRINE SYSTEM : Endocrine system is the system formed by ductless glands which secrete chemical substances called as hormones. Endocrine glands release hormones directly into the blood.
Hormones are minute, chemical messengers thrown into blood to act on target organs.
Hormones can be steroids, proteins, peptides or amino acid derivatives.
These hormones act as on specific organs called target organ.
The target cell has on it surface or cytoplasm, a specific protein molecule called receptor.
The receptor can recognise and pick out the specific hormone capable of acting in cell.
The endocrine system includes glands that secrete hormones directly into the bloodstream to regulate distant target tissues and organs. The major glands are the pituitary, thyroid, parathyroid, adrenal, pancreas, gonads, thymus, and pineal. The pituitary gland regulates other endocrine glands by secreting hormones like growth hormone, TSH, and ACTH. The thyroid regulates metabolism and produces thyroxine and triiodothyronine. Disorders include hypothyroidism and hyperthyroidism. The pancreas produces insulin to regulate blood sugar levels, and diabetes occurs when there is insufficient insulin. Sex glands like the ovaries and testes produce hormones like estrogen, progesterone and test
The endocrine system maintains homeostasis through glands that secrete hormones to regulate functions like growth, metabolism, and reproduction. It interacts with other systems through hormones. The major glands are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pancreas, ovaries/testes. For example, the pituitary controls the thyroid and reproductive organs to regulate growth and menstrual cycles. Imbalances in hormones from endocrine organs can cause diseases.

There are special chemicals which act as hormones and provide chemical
coordination, integration and regulation in the human body. These hormones
regulate metabolism, growth and development of our organs, the endocrine glands
or certain cells. The endocrine system is composed of hypothalamus, pituitary
and pineal, thyroid, adrenal, pancreas, parathyroid, thymus and gonads (testis
and ovary). In addition to these, some other organs, e.g., gastrointestinal tract,
kidney, heart etc., also produce hormones. Progesterone plays a major role in the maintenance of pregnancy as
well as in mammary gland development and lactation. The atrial wall of the heart
produces atrial natriuretic factor which decreases the blood pressure. Kidney
produces erythropoietin which stimulates erythropoiesis. The gastrointestinal tract
secretes gastrin, secretin, cholecystokinin and gastric inhibitory peptide. These
hormones regulate the secretion of digestive juices and help in digestion.
The endocrine system includes glands that secrete hormones directly into the bloodstream to regulate bodily functions. The pituitary gland is called the "master gland" as it controls other glands by releasing hormones like growth hormone, thyroid stimulating hormone, and adrenocorticotropic hormone. Other major glands include the thyroid, which produces hormones regulating metabolism, the adrenals producing cortisol and aldosterone, and the gonads which are the ovaries and testes. The pancreas produces insulin and glucagon to regulate blood sugar levels. Hormones work through feedback loops and many function in pairs to control important processes like calcium levels and glucose regulation.

Viruses are extremely small, infectious agents that invade cells of all types. These have been culprits in many human disease including small pox,flu,AIDS and ever present common cold as well as plants bacteria and archea .
Viruses cannot multiply outside the living host cell, However the isolation, enumeration and identification become a difficult task. Instead of chemical medium they require a host body.
Viruses can be cultured in the animals such as mice ,monkeys, rabbits and guinea pigs etc. After inoculation animals are carefully examined for the development of signs or symptoms, further they may be killed.
Mapping the Growth of Supermassive Black Holes as a Function of Galaxy Stella...Sérgio Sacani
The growth of supermassive black holes is strongly linked to their galaxies. It has been shown that the population
mean black hole accretion rate (BHAR) primarily correlates with the galaxy stellar mass (Må) and redshift for the
general galaxy population. This work aims to provide the best measurements of BHAR as a function of Må and
redshift over ranges of 109.5 < Må < 1012 Me and z < 4. We compile an unprecedentedly large sample with 8000
active galactic nuclei (AGNs) and 1.3 million normal galaxies from nine high-quality survey fields following a
wedding cake design. We further develop a semiparametric Bayesian method that can reasonably estimate BHAR
and the corresponding uncertainties, even for sparsely populated regions in the parameter space. BHAR is
constrained by X-ray surveys sampling the AGN accretion power and UV-to-infrared multiwavelength surveys
sampling the galaxy population. Our results can independently predict the X-ray luminosity function (XLF) from
the galaxy stellar mass function (SMF), and the prediction is consistent with the observed XLF. We also try adding
external constraints from the observed SMF and XLF. We further measure BHAR for star-forming and quiescent
galaxies and show that star-forming BHAR is generally larger than or at least comparable to the quiescent BHAR.

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...Sérgio Sacani
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.
Measuring gravitational attraction with a lattice atom interferometerSérgio Sacani
Despite being the dominant force of nature on large scales, gravity remains relatively
elusive to precision laboratory experiments. Atom interferometers are powerful tools
for investigating, for example, Earth’s gravity1
, the gravitational constant2
, deviations
from Newtonian gravity3–6
and general relativity7
. However, using atoms in free fall
limits measurement time to a few seconds8
, and much less when measuring
interactions with a small source mass2,5,6,9
. Recently, interferometers with atoms
suspended for 70 s in an optical-lattice mode fltered by an optical cavity have been
demonstrated10–14. However, the optical lattice must balance Earth’s gravity by
applying forces that are a billionfold stronger than the putative signals, so even tiny
imperfections may generate complex systematic efects. Thus, lattice interferometers
have yet to be used for precision tests of gravity. Here we optimize the gravitational
sensitivity of a lattice interferometer and use a system of signal inversions to suppress
and quantify systematic efects. We measure the attraction of a miniature source mass
to be amass = 33.3 ± 5.6stat ± 2.7syst nm s−2, consistent with Newtonian gravity, ruling out
‘screened ffth force’ theories3,15,16 over their natural parameter space. The overall
accuracy of 6.2 nm s−2 surpasses by more than a factor of four the best similar
measurements with atoms in free fall5,6
. Improved atom cooling and tilt-noise
suppression may further increase sensitivity for investigating forces at sub-millimetre
ranges17,18, compact gravimetry19–22, measuring the gravitational Aharonov–Bohm
efect9,23 and the gravitational constant2
, and testing whether the gravitational feld

Discovery of Merging Twin Quasars at z=6.05Sérgio Sacani
We report the discovery of two quasars at a redshift of z = 6.05 in the process of merging. They were
serendipitously discovered from the deep multiband imaging data collected by the Hyper Suprime-Cam (HSC)
Subaru Strategic Program survey. The quasars, HSC J121503.42−014858.7 (C1) and HSC J121503.55−014859.3
(C2), both have luminous (>1043 erg s−1
) Lyα emission with a clear broad component (full width at half
maximum >1000 km s−1
). The rest-frame ultraviolet (UV) absolute magnitudes are M1450 = − 23.106 ± 0.017
(C1) and −22.662 ± 0.024 (C2). Our crude estimates of the black hole masses provide log 8.1 0. ( ) M M BH = 3
in both sources. The two quasars are separated by 12 kpc in projected proper distance, bridged by a structure in the
rest-UV light suggesting that they are undergoing a merger. This pair is one of the most distant merging quasars
reported to date, providing crucial insight into galaxy and black hole build-up in the hierarchical structure
formation scenario. A companion paper will present the gas and dust properties captured by Atacama Large
Millimeter/submillimeter Array observations, which provide additional evidence for and detailed measurements of
the merger, and also demonstrate that the two sources are not gravitationally lensed images of a single quasar.

Centrifugation is a technique, based upon the behaviour of particles in an applied centrifugal filed.
Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed.
The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis.

The use of probiotics and antibiotics in aquaculture production.pptxMAGOTI ERNEST
Aquaculture is one of the fastest growing agriculture sectors in the world, providing food and nutritional security to millions of people. However, disease outbreaks are a constraint to aquaculture production, thereby affecting the socio-economic status of people in many countries. Due to intensive farming practices, infectious diseases are a major problem in finfish and shellfish aquaculture, causing heavy loss to farmers (Austin & Sharifuzzaman, 2022). For instance Bacterial fish diseases are responsible for a huge annual loss estimated at USD 6 billion in 2014, and this figure has increased to 9.58 in 2020 globally.
Disease control in the aquaculture industry has been achieved using various methods, including traditional means, synthetic chemicals and antibiotics. In the 1970s and 1980s oxolinic acid, oxytetracycline (OTC), furazolidone, potential sulphonamides (sulphadiazine and trimethoprim) and amoxicillin were the most commonly used antibiotics in fish farming (Amenyogbe et al., 2020). However, the indiscriminate use of antibiotics in disease control has led to selective pressure of antibiotic resistance in bacteria, a property that may be readily transferred to other bacteria (Bondad‐Reantaso et al., 2023a). Traditional methods are ineffective against controlling new disease in large aquaculture systems. Therefore, alternative methods need to be developed to maintain a healthy microbial environment in aquaculture systems, thereby maintaining the health of the cultured organisms.

• Oxytocin: Manages aspects of the reproductive systems and human behavior, including labor, delivery, and
lactation
• Parathyroid hormone: Controls calcium levels in bones and blood
• Progesterone: Helps prepare the body for pregnancy
