This presentation summarizes the effects of agricultural chemicals on male and female reproduction. It discusses how chemicals like DBCP, chlordecone, and ethylene dibromide impact male reproduction by increasing Sertoli cell number, degenerating seminiferous tubules, and inhibiting sperm motility and viability. It also examines how chemicals such as DDT, organophosphates, carbamates, chlordecone, and HCB affect female reproduction by influencing hormone levels, uterine weight, conception rates, and embryo development. The presentation provides references from literature on the reproductive effects of natural toxins.

The document discusses the effect of p53 status on the induction of the GADD45a gene in response to genotoxic stress. It finds that: 1) Loss of the p53 response element (RE) or presence of mutated p53 decreases or abrogates the induction of GADD45a for compounds that produce a positive response in the GreenScreen HC assay. 2) P53 is required for optimal induction of GADD45a and regulates it through the intron region. 3) The use of wild-type p53 cells and regulatory sequences involved in the genotoxic stress response is critical to the performance of the GreenScreen HC assay.

This document discusses genetic polymorphisms and their role in disease pathogenesis and complications. It begins with definitions of health and disease, then discusses various disease causative agents including environmental, genetic, and microbial factors. It describes the organization of the human genome and genes. The document outlines DNA structure and organization, including DNA packaging into chromosomes. It discusses polymorphisms, mutations, and how they can be analyzed using restriction endonucleases and techniques like PCR and gel electrophoresis. Specific examples are provided of how genetic variations can impact disease by changing enzymes, receptors, transport proteins, and other molecular factors.

This document discusses the use of platelet rich plasma (PRP) for the treatment of tendon injuries in horses. PRP involves concentrating the platelets found in a horse's own blood, which contain growth factors, and injecting them into an injured tendon to aid the healing process. The document reviews what PRP is, how it is prepared, common indications for its use, and the procedure for administering PRP to a tendon lesion in a horse.

Genotoxicty Presented By Subin Joy Koikkarasubinkoikkara

This document provides details on an experiment to detect DNA damage in human peripheral leukocytes induced by three carbamate pesticides: methomyl, carbaryl, and carbendazim. The aim was to use the alkaline comet assay to check if these pesticides cause genotoxicity at the cellular level. Blood samples were treated with different concentrations of each pesticide and the comet assay was performed. Results showed that all three pesticides caused DNA damage in leukocytes, as demonstrated by increased tail length and tail movement, at concentrations as low as 25-50 parts per million. The conclusion is that long-term exposure to these carbamate pesticides may have clastogenic effects on somatic cell DNA and should be considered non

iDiffIR: Identifying differential intron retention from RNA-seqAraport

��

This document describes iDiffIR, a method for identifying differential intron retention (IR) from RNA-seq data. iDiffIR was tested on several plant and human datasets and was able to detect biologically significant differential IR events. It is robust to factors like expression changes and library size differences between samples. The authors integrated iDiffIR with the ARAPORT database so results can be viewed alongside gene annotations. iDiffIR is available online and can help study alternative splicing regulation across conditions.

Black sesame seeds information@abdul haiMd Abdul Hai

��

Black sesame seeds provide many health benefits such as anti-aging properties by fighting age-related symptoms like hearing loss and poor eyesight. They also promote heart health by lowering cholesterol and blood pressure. Additionally, black sesame seeds aid in digestion and lactation, reduce anxiety, relieve arthritis pain and inflammation, and increase respiratory and vascular health. The seeds are a good source of fiber, protein, vitamins, minerals, and antioxidants. They can be eaten raw or sprinkled on foods and blended into smoothies to enjoy their nutty flavor and health properties.

Solar energy by hadi @bauMd Abdul Hai

��

Solar energy can be harnessed using technologies like solar heating, photovoltaics, and concentrating solar power. There are two main types - passive solar, which uses sunlight without external mechanical power, and active solar, which uses mechanical or electrical power. Solar energy can be directly converted to electricity via photovoltaic panels or indirectly via solar thermal collectors that capture heat. Large solar power plants use thousands of solar panels or mirrors to generate electricity on a utility scale. Solar energy can be stored using batteries in off-grid homes or by feeding excess electricity to the grid via net metering.

Flag screening is a crucial part of physiotherapy assessment that helps in identifying medical, psychological, occupational, and social barriers to recovery. Recognizing these flags ensures that physiotherapists make informed decisions, provide holistic care, and refer patients appropriately when necessary. By integrating flag screening into practice, physiotherapists can optimize patient outcomes and prevent chronicity of conditions.
