Histology Of Liver
The document provides information about the structure and function of the liver:
- The liver is covered by Glisson's capsule and is divided into lobules that contain hepatocytes arranged in plates separated by sinusoids. Bile canaliculi between hepatocytes drain into ductules.
- Blood enters the liver through the hepatic portal vein and hepatic artery and flows through sinusoids before draining into the hepatic veins.
- The liver performs many metabolic functions like detoxification, protein synthesis, and glucose regulation. It also stores vitamins, glycogen, and lipids. Bile produced by hepatocytes is secreted into small bile ducts and stored in the gallbladder.
Histology of liver by aravindh dpi
The liver is composed of repeating lobules that contain hepatocytes radiating from a central vein. Between hepatocytes are sinusoids lined with endothelial cells and Kupffer cells. Bile canaliculi connect hepatocytes and drain bile into interlobular bile ducts. The perisinusoidal space of Disse contains fibers and lipocytes between sinusoids and hepatocytes. There are three types of lobules - classical with peripheral to central blood flow, portal defined by a bile duct, and acinar surrounding a central artery in three oxygen zones. Hepatocytes are polyhedral cells that contact sinusoids through spaces of Disse.

Liver
The liver originates in the third week of development as an outgrowth of endodermal epithelium in the foregut called the hepatic diverticulum. This divides into the larger cranial pars hepatica and caudal pars cystica. The pars hepatica gives rise to hepatocytes, sinusoids, and other liver cells and tissues. The pars cystica develops into the gallbladder and cystic duct. By the 12th week, bile production begins and the liver fills much of the abdominal cavity, taking on its adult shape with two lobes.
Biomembrane and cell signalling
This document discusses the transport of substances across epithelial cells that line various tissues in the body. It explains that epithelial cells are polarized, with transporters located specifically in the apical or basolateral membranes. Glucose absorption in the small intestine is used as an example, where glucose enters cells via the sodium-glucose cotransporter on the apical surface and exits into the blood via the glucose transporter on the basolateral surface. Intestinal fluid secretion is also summarized, involving the transport of chloride ions into and out of cells.
Urinary system
The urinary system functions to filter waste from the blood and regulate fluid levels. The kidneys contain nephrons, which are the functional filtering units. Each nephron contains a renal corpuscle with glomerulus for blood filtration, and a renal tubule for reabsorption and secretion. Filtrate passes through the glomerulus and along the tubule, where it is modified before collection in the ureters and storage in the bladder for excretion. The juxtaglomerular apparatus regulates blood pressure and fluid balance.
Liver slides
The document describes the structure and organization of the liver. The liver contains lobules that are organized in three patterns - classic, portal, and liver acinus. The classic lobule is hexagonal in shape with a central vein in the middle and a portal triad at the boundaries. Portal lobules connect three central veins in a triangle shape. Liver acini are diamond shaped and bordered by two central veins and portal triads. Within the lobules, blood flows through sinusoids while bile flows in bile canaliculi, which is between hepatocytes and bounded by tight junctions, in the opposite direction to blood towards the bile ducts. Lymph flows within the space of disse, located between hepatocytes and sin
Occupational Liver Disorders
This document discusses occupational liver disorders and their causes. It covers viral, chemical, and physically induced liver injuries and diseases. Some key points include:
1. The liver is divided into three zones (periportal, midzonal, centrilobular) that are differentially affected by toxins.
2. Occupational liver disorders are challenging to diagnose due to non-specific symptoms and potential simultaneous conditions like viral hepatitis or substance abuse.
3. Serologic markers and liver enzymes can help identify liver damage and its cause. Cytotoxic injuries elevate less liver-specific enzymes while cholestatic injuries increase enzymes like alkaline phosphatase.
4. Chemicals from many industries can cause liver

It discusses the roles of monocytes, neutrophils, eosinophils, basophils, T cells (helper, killer, memory), and B cells. The innate system's physical and chemical barriers are described, as well as the inflammatory response. The adaptive system is mediated by lymphocytes that recognize, destroy, and remember pathogens.
FATTY LIVER
Fatty liver, or hepatic steatosis, refers to excess triglyceride accumulation in liver cells. This can be caused by increased fatty acid mobilization from adipose tissue, excess fatty acid synthesis in the liver, or reduced removal of fat from the liver. Common causes include obesity, uncontrolled diabetes, high-fat diet, alcoholism, and deficiencies in lipotropic factors like choline, betaine, and inositol. Untreated, fatty liver can progress to non-alcoholic steatohepatitis and fibrosis or cirrhosis of the liver.
The Function of the pancreas
The pancreas is located deep in the body behind the stomach. It is shaped like a fish and produces proteins, sodium bicarbonates, and pancreatic juices. These juices mix with bile from the liver and gallbladder and empty into the small intestines, where they neutralize stomach acids and help digest food into smaller pieces, demonstrating the important role the pancreas plays in the body's digestive functions.
Drug induced hepatotoxicity and its regulatory implications
Drug induced hepatotoxicity
Hepatotoxicity implies chemical-driven liver damage. Liver injury may be produced by a large variety of chemical substances The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents Certain medicinal agents, when taken in overdoses & sometimes even when introduced within therapeutic ranges may injure the liver It might not be the drug that cause hepatotoxicity but its metabolite might The herbal drugs and agents can also cause the liver injury
Anatomy of liver
The document describes the anatomy of the liver including its lobes, ligaments, surfaces, blood supply and drainage. It notes the H-shaped set of grooves on the visceral surface containing the porta hepatis, gallbladder fossa, and ligaments. Practical assignments are provided to study the peritoneal attachments, locate structures in the porta hepatis, and explore the vasculature and innervation of the liver and pancreas.
Biochemistry of liver&muscles
The liver plays a key role in metabolizing nutrients, producing proteins and biochemicals, and detoxifying compounds. It breaks down carbohydrates like glucose, synthesizes proteins, and metabolizes fats. The liver also detoxifies toxins and drugs using a two-phase process involving cytochrome P450 enzymes and conjugation reactions. Cytochrome P450 monooxygenases introduce reactive oxygen into compounds in phase 1, and phase 2 involves adding polar groups like glucuronic acid to make compounds more water-soluble and easier to excrete. The liver's central role in metabolism makes it vital for whole-body homeostasis.
Digestion and absorption of proteins
This document summarizes the digestion and absorption of proteins. It explains that proteins are broken down into amino acids by proteolytic enzymes in the stomach, pancreas, and small intestine. These amino acids are then absorbed into the bloodstream through active transport mechanisms in the intestinal epithelium. Genetic disorders like Hartnup's disease and cystinuria can impair amino acid transport and cause amino acids to be lost in urine or feces.
Protein digestion
Protein digestion is a two-step process involving enzymes in the stomach and small intestine. In the stomach, pepsin breaks down proteins into smaller polypeptides and some amino acids. In the small intestine, proteases like trypsin and peptidases further break down polypeptides into dipeptides and individual amino acids, which are then absorbed. Tests like Biuret can detect the presence of proteins and the completeness of digestion. Factors like pH, temperature, and inhibitors affect the efficiency of protein digestion.
Pancreas function
The document summarizes key aspects of pancreatic function and disease. It discusses how the pancreas secretes enzymes and fluid to aid digestion. The two major hormones that regulate secretion are secretin and cholecystokinin. Acute pancreatitis can result from factors like gallstones, alcohol use, or hypertriglyceridemia and involves inflammation and damage to pancreatic tissue that can spread systemically. Chronic pancreatitis is characterized by irreversible pancreatic damage and can be caused by long-term alcohol use, genetic mutations, or recurrent acute pancreatitis. Laboratory tests of pancreatic enzymes and hormone stimulation help diagnose pancreatic disorders.

Liver cirrhosis
This document discusses liver cirrhosis, including its types, causes, pathophysiology, clinical manifestations, complications, nursing diagnoses, and interventions. Liver cirrhosis is a chronic, degenerative disease characterized by replacement of normal liver tissue with fibrosis that disrupts liver structure and function. Common types are alcoholic cirrhosis and postnecrotic cirrhosis resulting from viral hepatitis. Complications include ascites, hepatic encephalopathy, and esophageal varices, which can lead to life-threatening bleeding if ruptured. Nursing care focuses on reducing metabolic demands, providing adequate nutrition and hydration, preventing infection, and protecting patients from injury and further complications.
Cirrhosis of liver
Cirrhosis is a diffuse process characterized by liver necrosis and fibrosis that converts the normal liver architecture into abnormal nodules lacking a normal lobular organization. It has many causes including viral hepatitis infections, alcohol toxicity, autoimmune diseases, and genetic disorders. Pathologically, cirrhosis involves nodularity, fibrosis from collagen deposition, and abnormal hepatocyte changes. Portal hypertension develops due to increased resistance to blood flow from architectural disruption of the cirrhotic liver, leading to formation of portosystemic collaterals that bypass the liver. The severity of cirrhosis is classified using the Child-Pugh or MELD scoring systems to determine prognosis and need for transplantation.
Histology of normal liver
The liver is the second largest organ and largest gland in the body. It has a dual blood supply and is divided into lobules that contain hepatocytes, sinusoids, and a central vein. Blood flows into lobules through the portal vein and hepatic artery and out through hepatic veins. Hepatocytes are arranged in plates separated by sinusoids and produce bile that flows into canaliculi and out of the liver. The liver has regenerative abilities and its segmentation allows for resection of parts without damaging remaining tissue.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
