The document discusses haemopoiesis (blood cell formation) and the histology of bone marrow. It describes how in fetal life, blood cells are formed in the yolk sac, liver, and later the bone marrow and liver. In newborns, children and adults, red bone marrow is found in all bones up to age 20, and later in flat bones and ends of long bones. Bone marrow contains hematopoietic stem cells that differentiate into the various blood cell lineages through progenitor and precursor cells in the bone marrow microenvironment.

Fluid cytology in serous cavity effusionstashagarwal
The intrathoracic and intraperitoneal organs are covered by a single layer of mesothelial cells, which is continuous with the lining of the thoracic and peritoneal cavities. The potential space between the two layers of epithelium contains a small amount of lubricating fluid.
Serous fluid lies between the membranes lining the body cavities(parietal) and those covering the organs within the cavities(visceral).
Production and reabsorption are normally at a constant rate. They are influenced by
Changes in osmotic and hydrostatic pressure in the blood.
Concentration of chemical constituents in the plasma
Permeability of blood vessels and membranes.
An accumulation of fluid, called an effusion, results from an imbalance of fluid production and reabsorption. This fluid accumulation in the pleural, pericardial, and peritoneal cavities is known as serous effusion.

Hematopoiesis is the process of blood cell production, differentiation, and development. hematopoeisis starts in yolk sac in the fetus and continued in he liver, spleen and bone marrow. In adult, hematopoeisis occurs in bone marrow.
Erythropoiesis is the process of RBC production. erythroproietin stimulate RBC production (initially CFU-E ) in response of hypoxia.
Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. In vertebrates, it is composed of blood cells suspended in blood plasma.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.

MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

9. Where did they come from???
Origin, development and Maturation of Blood cells called as
Haemopoiesis
Origin, development and Maturation of Red Blood cells
called as Erythropoiesis
In adult its from BONE MARROW
What about Fetus ? New Born ? Old Age ?
DrRadhakrishnan
10. IN FETAL LIFE
1. Mesoblastic Stage (upto 2 months)
Mesenchyme of yolk sac.
2. Hepatic Stage (3-6 months)
Liver and also Spleen and lymphoid
organs
3. Myeloid Stage(last 3 months)
Red bone marrow and liver.
Site of Erythropoiesis „
DrRadhakrishnan
11. IN NEWBORN BABIES, CHILDREN AND ADULTS
1. Up to the age of 20 years:
Red bone marrow of all bones (long bones and all the flat
bones).
2. After the age of 20 years:
Membranous bones like vertebra, sternum, ribs, scapula, iliac bones
and skull bones and from the ends of long bones.
After 20 years of age, the shaft of the long bones becomes yellow
bone marrow because of fat deposition and looses the erythropoietic
function.
DrRadhakrishnan
12. What is Bone marrow & Where do you find it ???
Soft pulpy tissue found in marrow cavities of all bones
DrRadhakrishnan
13. What is Bone marrow & Where do you find it ???

21. Stages of Erythropoiesis Important events
Proerythroblast Synthesis of Hb starts
Early Erythroblast Nuclei disappear
Intermediate Erythroblast Hb starts appearing
Late Erythroblast Nucleus disappears
Reticulocyte Reticulum formed. Cells enter
into capillary from site of
production
Mature RBC Reticulum disappears. Cell attain
Biconcavity
Cells of CFU-E pass through different stages and finally become the matured RBCs.
During these stages four important changes are noticed.
1. Reduction in size of the cell (from the diameter of 25 to 7.2 µ)
2. Disappearance of nucleoli and nucleus
3. Appearance of hemoglobin
4. Change in the staining properties of the cytoplasm. „
