The initial macroscopic examination of semen includes observing liquefaction, viscosity, appearance, volume, and pH. Liquefaction normally occurs within minutes at room temperature and may contain jelly-like granules. Viscosity is estimated by allowing a sample to drop and observing the length of any thread formed, with >2cm indicating high viscosity. Appearance can provide clues to conditions like infection or illness. Normal volume is 2-5mL. pH should be measured 30 minutes after liquefaction and typically ranges from 6.0-7.0.

Peripheral Smear Using Leishman Stain
This document provides instructions for performing a peripheral blood smear, including preparation of materials, staining technique, examination under the microscope, and diagnostic value. A peripheral smear involves making a thin blood film on a slide, staining it using Leishman's stain, and examining under oil immersion to identify red blood cells, white blood cells, platelets, and any parasites present. A differential white blood cell count is also performed to classify types of white blood cells. The smear allows evaluation of cell morphology and identification of abnormalities.
H006 preparation of smear and staining
This document provides instructions for preparing a blood smear and staining it using Leishman's stain and Wright's stain. It outlines the materials needed, including slides, a spreader, blood mixed with EDTA, and staining reagents. The procedure explains how to make a blood smear, allowing it to dry before staining. For Leishman's stain, the smear is covered with stain for 2 minutes, diluted with buffer, and stained for 7-10 minutes. For Wright's stain, the smear is stained for 1-2 minutes, diluted with buffer, and stained for 3-5 minutes. Internal quality controls include ensuring the smear is the proper shape and size and that solutions are not expired.

Preparation and staining of peripheral blood smear
This document provides instructions for preparing and staining a peripheral blood smear. It describes how to make a thin blood film using the wedge technique and a thick blood film for diagnosing parasites. Potential sources of error in film preparation are outlined. The document then explains the staining process for Leishman's stain and Giemsa stain, including stain preparation, application to blood films, and differentiation to distinguish cells under the microscope. The stains are used to identify cells after a blood film has been prepared.
Prepration and staining of blood film
1. A peripheral blood film (PBF) is a thin layer of blood smeared on a microscope slide that is stained to allow examination of blood cells.
2. An ideal blood smear is uniformly thick, occupies the central portion of the slide, and tapers from thick at the head to thin at the tail.
3. Preparation involves using a spreader slide at a 40-45 degree angle to pull blood into a feathered tongue shape from a drop of blood on the slide.
Ps
A peripheral smear is a thin layer of blood used to examine red blood cells (RBCs) and white blood cells (WBCs) under a microscope. There are two types of smears - thin smears and thick smears. Thin smears are prepared by spreading blood into a thin layer on a slide and are used to observe cell morphology and detect anemias and leukemias. Thick smears use more blood spread in an oval shape and are prepared and examined similarly, but are used specifically to detect parasitic infections like malaria.
Osmosis
The document describes an experiment to demonstrate osmosis using a potato osmometer. Key steps of the procedure include slicing a potato and creating a cavity, filling half the cavity with a 20% sucrose solution, and submerging the potato in water. Over about an hour, osmosis occurs where water moves from the higher water potential area (the beaker of water) through the potato and into the lower water potential area (the sucrose solution), causing the level of the sucrose solution to rise. This demonstrates how a selectively permeable membrane like the potato tissues allows for osmosis and the movement of water across membranes to equalize water potential gradients.
Peripheral smear staining and morphology
This document provides information on preparing and staining peripheral blood smears (PBS). It discusses how to make a wedge blood smear using the correct technique and equipment. It also describes how to evaluate a quality smear and identify common causes of poor smears. The document outlines the staining process for PBS, including the history and components of Romanowsky staining methods like Wright-Giemsa and May-Grunwald Giemsa. Factors that can influence staining and cause faulty results are discussed. Finally, it provides guidance on examining a PBS under the microscope, including evaluating red blood cells, white blood cells, platelets, and identifying any parasites.

Semen contains spermatozoa and seminal plasma secreted from glands. Semen stains may be examined in criminal cases like rape. Samples are collected without heat and packaged carefully. Screening tests examine color, fluorescence under UV light, and chemical tests for choline or spermine. Confirmatory tests identify intact spermatozoa under microscopy or seminal markers like acid phosphatase. Motility can determine timing of deposition. Species origin is confirmed by precipitin tests, LDH patterns, or presence of human-specific Y bodies in sperm.
Lab 12 blood film
This document discusses the process of making and staining a blood film to identify blood-borne parasites under a microscope. It describes how to collect a blood sample, make thick and thin blood films on a slide, and stain the films using a Leishman or Wright stain. The staining process colors nuclei dark blue/violet, erythrocytes pale pink, and cytoplasm pale blue, allowing identification of parasites like malaria. Thin films show intact red blood cells and species differentiation while thick films show lysed cells and higher parasite density.
Tear function tests
The tear film provides several important functions for the eye, including polishing the corneal surface, trapping and flushing out debris, and reducing friction during eye movement. Several tests are used to evaluate the tear film and diagnose dry eye, including the BUT test, NIBUT test, Schirmer's test, fluorophotometry, phenol red thread test, Rose Bengal staining test, and tear osmolality test. Each test measures different aspects of the tear film and has defined normal and dry eye results.
Embalming
Embalming is the process of chemically treating human and animal remains to reduce decomposition and restore acceptable physical appearance. It originated in Egypt around 3200 BC and was later used by anatomists in the 15th century to preserve bodies for medical research. The modern embalming process involves arterial injection of embalming fluid containing formaldehyde, glutaraldehyde, or ethanol to sanitize and preserve the body. Additional cavity embalming and surface treatments may also be used. Embalming allows for public visitations and delays decomposition so the body remains suitable for study.
Preparation of blood films for malaria parasites
This document provides instructions for preparing blood films for malaria parasite detection. It describes making both a thick blood smear from a fingerprick to see if parasites are present and a thin blood smear to identify the Plasmodium species. Proper technique and labeling are emphasized, including using gloves, cleaning the finger, making slides of the right thickness, and allowing complete drying. Venous blood can also be used if slides are prepared within 2 hours to avoid changes affecting identification.
special and routine stains in haematology 1
The document discusses various routine and special stains used in hematology. Routine stains like Leishman, Giemsa, and Wright stains are used to stain peripheral blood films and differentiate blood cells. Special stains require additional processing but can identify characteristics not seen with routine stains, such as periodic acid Schiff stain which detects carbohydrates like glycogen by oxidizing glycol groups and producing a red reaction. Proper staining techniques such as fixation, washing, and timing are important for preparing clear blood smears and accurately identifying blood components.

Semen Analysis
Semen examination provides important evidence in sexual assault cases. Semen is composed of sperm cells suspended in seminal fluid. Initial presumptive tests for semen examine for the presence of enzymes like acid phosphatase. Confirmatory testing requires microscopic examination of the stain to identify sperm cells, as their presence confirms the source was human semen. Proper collection and handling of evidence from victims and suspects is crucial, as it allows laboratory examination to detect potential DNA transfers that can identify assailants. Semen evidence plays a key role in medico-legal cases involving rape, sodomy, incest, and disputed paternity.

Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
biomechanics of running. Dr.dhwani.pptx
The biomechanics of running involves the study of the mechanical principles underlying running movements. It includes the analysis of the running gait cycle, which consists of the stance phase (foot contact to push-off) and the swing phase (foot lift-off to next contact). Key aspects include kinematics (joint angles and movements, stride length and frequency) and kinetics (forces involved in running, including ground reaction and muscle forces). Understanding these factors helps in improving running performance, optimizing technique, and preventing injuries.

PGx Analysis in VarSeq: A User’s Perspective
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

Seman analysis part 3
- 1. Seman Analysis part -3 Seman Macroscopic Examination Medical technologist: Zubair Ahmed Motivational Science T.V💉
- 2. Initial macroscopic examination: •Liquefaction 1. Within a few minutes at room temperature, the semen usually begins to liquefy 2. Normal liquefied semen samples may contain jelly-like granules (gelatinous bod- ies) •Semen viscosity After liquefaction, the viscosity of the sample can be estimated by gently aspirat- ing it into a wide-bore (approximately 1.5 mm diameter) plastic disposable pipette, allowing the semen to drop by gravity and observing the length of any thread. •If viscosity is abnormal, the drop will form a thread more than 2 cm long. : High viscosity can interfere with determination of sperm motility, sperm concentration, detection of antibody- coated spermatozoa and measurement of biochemical markers sample usually liquefies within 15 minutes at room temperature
- 3. •Appearance of the ejaculate •A normal liquefied semen sample has a homogeneous, grey-opalescent appear- ance •It may appear less opaque if the sperm concentration is very low •red-brown when red blood cells are present (haemo- spermia), •yellow in a man with jaundice or taking certain vitamins •Semen volume: The volume of the ejaculate is contributed mainly by the seminal vesicles and prostate gland, with a small amount from the bulbourethral glands and epididy- mides • A normal amount is between 2 and 5 milliliters •Hypospermia is when the volume is less than 1.5 ml, • Hyperspermia is a large volume of more than 5.5 ml.
- 4. •Semen pH •The pH of semen reflects the balance between the pH values of the different accessory gland secretions •mainly the alkaline seminal vesicular secretion and the acidic prostatic secretion •The pH should be measured after liquefaction at a uniform time, preferably after 30 minutes, but in any case within 1 hour of ejacula- tion since it is influenced by the loss of CO2 that occurs after production •For normal samples, pH paper in the range 6.0 to 10.0 should be used. •Mix the semen sample well (see Box 2.3). •Spread a drop of semen evenly onto the pH paper. •Wait for the colour of the impregnated zone to become uniform (<30 seconds). •Compare the colour with the calibration strip to read the pH.
