Human Immunodeficiency Virus (HIV) is a retrovirus that infects host cells and uses their DNA to make its own viral DNA. It has a long incubation period between exposure and symptoms. HIV consists of RNA surrounded by a lipid envelope and infects immune cells like T-lymphocytes. It is transmitted through sexual contact, blood exposure, mother-to-child transmission, and sharing contaminated needles. While there is no cure for HIV, antiretroviral drug therapy can control the virus and prolong the lives of infected individuals.

AIDS is caused by the human immunodeficiency virus (HIV). Many people infected with HIV do not show symptoms for years, allowing them to infect others unknowingly. HIV weakens the immune system, leaving the body vulnerable to infections and diseases. The virus can be transmitted sexually, through blood exposure, or from mother to child during pregnancy, birth, or breastfeeding. While scientists have been unable to develop a vaccine, prevention focuses on avoiding risky behaviors like unprotected sex with multiple partners and sharing needles.A brief talk on hiv aids cmoh bankura

The document discusses the causes and effects of HIV. The main causes of HIV transmission are through unprotected sexual contact, sharing needles or syringes, and from mother to fetus during pregnancy or breastfeeding. Some effects of HIV include skin conditions like chicken pox or shingles that can affect organs and be life-threatening, as well as AIDS-related dementia which decreases cognitive ability and processing due to neurological impacts even though HIV does not directly infect nerve cells.HIV/AIDS

This document provides information about HIV/AIDS, including:
- HIV causes AIDS by breaking down the immune system. AIDS is the most advanced stage of HIV disease.
- Scientists believe HIV originated from chimpanzees in Western Africa and jumped to humans through contact with infected animals.
- The earliest known case of HIV in humans was in 1959 in the Congo. The epidemic then spread among high-risk groups and an estimated 5% of gay men in New York and San Francisco had HIV by 1978.
- AIDS was first observed clinically in 1981 in the US in drug users and gay men with rare infections. Soon the CDC formed a task force to monitor the outbreak.Seminar presentation on HIV at Joseph Ayo Babalola Uni

This document summarizes information about HIV/AIDS. It begins by noting that the first reported HIV case was in 1981 and the virus was isolated in 1983. There are two types of HIV - HIV-1 and HIV-2. HIV is believed to have originated from closely related viruses found in non-human primates. The virus is transmitted primarily through unprotected sexual intercourse and contaminated blood/needles. While antiretroviral therapy has slowed the pandemic, there is still no cure for HIV/AIDS. The document outlines the pathogenesis, clinical stages, diagnosis, and transmission routes of HIV in further detail over multiple pages.Hiv aids presentation

HIV originates from non-human primates in Africa and was transmitted to humans through bushmeat consumption and exposure to infected blood. It has evolved into a global pandemic transmitted primarily through sexual contact, blood transfusions, and from mother to child. The virus infects CD4 cells of the immune system and progresses through four stages - from an initial infection with flu-like symptoms, to a long asymptomatic stage, then a symptomatic stage with opportunistic infections, and finally AIDS where the immune system is severely compromised. While there is no cure for HIV/AIDS, antiretroviral treatment can effectively control the virus and prevent transmission from mother to child.Hiv/aids presentation

HIV stands for human immunodeficiency virus and causes AIDS (acquired immunodeficiency syndrome). HIV weakens a person's immune system by destroying important cells that fight disease. AIDS is the final stage of HIV infection where the immune system is severely damaged. HIV is transmitted through direct contact with infected blood, semen, vaginal fluids, breast milk and rectal fluids. Common ways of transmission include unprotected sex and needle sharing. While there is no cure for HIV/AIDS, the risk of transmission can be reduced through safe sex practices and access to treatment.Hiv aidS

HIV was discovered in 1983-1984 as the cause of AIDS. It is a retrovirus that infects CD4+ T cells and causes AIDS by destroying the immune system. There are three main stages of HIV infection: acute infection, clinical latency, and AIDS. AIDS is diagnosed when the CD4 count drops below 200 or one of over 20 opportunistic infections or cancers develops. Antiretroviral treatment can suppress the virus and prolong the clinical latency phase.AIDS

It explains that HIV is a retrovirus that causes AIDS by infecting and damaging the immune system. HIV is transmitted via bodily fluids and can be passed from mother to child during pregnancy, birth, or breastfeeding. While HIV infection may be asymptomatic for years, it eventually leads to AIDS if untreated, characterized by life-threatening opportunistic infections. Laboratory diagnosis of HIV infection involves serological tests to detect HIV antibodies.Aids

HIV stands for Human Immunodeficiency Virus. It weakens a person's immune system by destroying white blood cells, making the body vulnerable to other infections and diseases. HIV is transmitted through unprotected sex, sharing needles, unsafe blood transfusions, and from mother to child during pregnancy, childbirth or breastfeeding. While some people experience flu-like symptoms shortly after infection, many live asymptomatic for years before developing AIDS. There is no vaccine or cure for HIV/AIDS, so prevention through safe sex practices and access to treatment are important.Prevention Of HIV/AIDS

Human Immunodeficiency Virus (HIV) is a retrovirus that inserts itself into human cells and reprograms their genetic structure. There is an incubation period before symptoms develop, which can take years. HIV is transmitted through unprotected sexual contact, sharing needles, or from mother to child during birth or breastfeeding. Diagnosis involves antibody and viral load testing. Left untreated, HIV weakens the immune system and increases the risk of infections, cancers, neurological and gastrointestinal issues. Treatment involves antiretroviral therapy to suppress the virus and prevent transmission.AIDS PRESENTATION

The document discusses Acquired Immunodeficiency Syndrome (AIDS). It begins by defining AIDS as a set of symptoms and infections resulting from damage to the human immune system by the human immunodeficiency virus (HIV). HIV is a retrovirus that targets CD4 T-cells and incorporates its genetic material into the host cell. The document then covers the epidemiology, risk factors, signs and symptoms, diagnosis, management and prevention of HIV/AIDS.Child Healthcare: HIV infection

Most HIV infections occur in Africa, where over 40 million people are infected. HIV is usually spread through sexual intercourse or from mother to child during pregnancy, childbirth, or breastfeeding. The risk of mother-to-child transmission can be reduced through antiretroviral treatment and avoiding breastfeeding if replacement feeding is acceptable, feasible, sustainable, and safe. HIV infection is diagnosed through antibody tests or PCR testing. Early diagnosis allows for earlier treatment and monitoring of infected infants.Child Healthcare: HIV infection

HIV is a virus that causes AIDS by weakening a person's immune system. It is transmitted via bodily fluids from sexual contact, contaminated needles, or from mother to child. While some people show no early symptoms, others experience a brief flu-like illness within weeks. Over time, HIV destroys immune cells called CD4 cells, leaving the body vulnerable to infections and cancers that define AIDS. Antiretroviral treatment can suppress HIV and prolong life, but does not cure it. Risk is reduced by condom use, treatment of STDs, male circumcision, and use of sterile needles by drug users.AIDS

This document discusses signal transduction and how it relates to cancer. It describes how growth factors and receptors contribute to normal signal transduction and how this process is deregulated in cancer. It explains that growth factors regulate growth, proliferation and survival, which are all altered in cancer. Several growth factors and receptors that can contribute to oncogenesis are identified. It also summarizes several key intracellular signaling pathways, like MAPK pathways, that are activated by growth factors and can result in the cancer phenotype if altered.Cells
CellsDeepika Tripathi

Cells are the basic unit of life and come in two main types - prokaryotic and eukaryotic. Eukaryotic cells are generally larger and more complex, containing membrane-bound organelles like the nucleus and mitochondria. Organelles specialize cells to carry out specific functions like protein production or energy generation. Cells range in size from a few microns to over a meter in some plant and animal cells.Chromosomal Inheritance
Chromosomal InheritanceDeepika Tripathi

Chromosomes contain genes and determine inheritance patterns. During meiosis, each sex cell receives half the number of chromosomes as somatic cells. Sex chromosomes (X and Y) determine sex, with females usually being XX and males XY. Sex-linked traits are found on the X chromosome and are expressed differently in males versus females. Nondisjunction can result in extra or missing chromosomes, causing conditions like Down syndrome. Sexual determination is based on the number of sex chromosomes, with a single Y resulting in a male phenotype. Modes of inheritance include autosomal dominant, autosomal recessive, and sex-linked traits.Epidermis

Cancer is a disease caused by uncontrolled cell growth that can form tumors. Cancer cells may spread, or metastasize, to other parts of the body. Cancer Cell is a journal focused on cancer research from basic to clinical studies, with an emphasis on translational research. Cancer cells are formed through genetic mutations in normal cells over many years. Cancer cells have properties like unlimited growth, lack of apoptosis and telomere shortening, angiogenesis, and metastasis that make them different from normal cells. Research on cancer prevention and control focuses on altering risky behaviors, increasing cancer screening, and improving diagnosis and survivorship.Presentation

Neurotransmitters are chemicals that transmit signals between neurons. They are synthesized in the presynaptic neuron, stored in vesicles, and released into the synaptic cleft upon arrival of an action potential. They then bind to receptors on the postsynaptic neuron, eliciting a biological response. Some major neurotransmitters include acetylcholine, dopamine, serotonin, GABA, and glutamate. Otto Loewi first discovered acetylcholine as a neurotransmitter in 1921. Neurotransmitters are classified as either excitatory or inhibitory depending on their effect on the postsynaptic neuron. Buffers help maintain pH and consist of a weak acid/base and its conjugate that can absorb hydrogen or hydroxide ions.Protein Synthesis
Protein SynthesisDeepika Tripathi

The document describes the process of protein synthesis through translation of mRNA. Messenger RNA is transcribed from DNA in the nucleus and binds to a ribosome on the endoplasmic reticulum. Transfer RNA molecules bring amino acids to the ribosome based on codon-anticodon base pairing between mRNA and tRNA. Peptide bonds form between amino acids as the ribosome moves along the mRNA, elongating the growing polypeptide chain until a stop codon is reached and protein synthesis is complete.Protien

The document discusses various aspects of protein synthesis, including the mechanism of initiation, elongation, and termination in both prokaryotes and eukaryotes. It also covers topics like translational control, post-translational modifications, protein targeting, and degradation. Protein synthesis requires codon-anticodon interactions and several initiation, elongation, and termination factors that facilitate the assembly of the ribosome and movement along the mRNA during translation. A major difference between prokaryotes and eukaryotes is the initiation process, which involves mRNA scanning and multiple eukaryotic initiation factors.Rice

Rice is a grain that comes from plants in the grass family. It is native to tropical and subtropical Asia and Africa. Rice plants grow 2-6 feet tall and produce grains that provide over one-fifth of human calories globally. Rice comes in thousands of varieties and is one of the most important human foods, sustaining two-thirds of the world's population. Small-scale farmers produce about four-fifths of the world's rice for local consumption.Rice 1

Rice is a staple crop for over half the world's population and is primarily grown and consumed in Asia and other developing countries. While the Green Revolution led to increased rice yields, it also caused environmental and social problems through practices like monocropping and excessive pesticide use. Current issues in rice production include stagnating yields, pest resistance, and debates around genetically modifying rice. Efforts are underway to improve sustainability through crop rotation and reducing post-harvest losses.Hiv

Human Immunodeficiency Virus (HIV) is a retrovirus that infects host cells and uses their DNA to make its own viral DNA. It has a long incubation period between exposure and symptoms. HIV consists of RNA surrounded by a lipid envelope and infects immune cells like T-lymphocytes. It is transmitted through sexual contact, blood exposure, mother-to-child transmission, and shared needles. While there is no cure for HIV, antiretroviral drug therapy can control the virus and prolong the lives of infected individuals.Cancer signal-transduction

Unprotected Vaginal or Anal intercourse may result in receiving the virus. Oral sex : The risk of HIV transmission through the throat, gums or any other oral membranes has a lower risk then receiving it from the vaginal or anal area.Sharing injection needles: Injecting a needle and sharing it with another person can result to transmitting of the virus. Mother to Child: A woman who has HIV can pass the virus directly to her child before, or during birth, or through breast milk. Breast milk contains HIV, small amounts of breast milk doesn't effect adults, it can be transmitted to infants.
- 43. Treatment For HIVThere is no cure for HIV yet. Medical professionals are working on a cure for it, but there are some treatments.Drug therapy for patients who are devoted to taking all off their medication and have A CD4 count lower than 350 mL, which shows their immune system is subdued. Pregnant women and people who have kidney or neurological problem related to HIV, probably need treatment regardless of their CD4 Count. It's important to take all of their medication or the virus will quickly become resistant to the drugs.Antiretroviral drugs (ARVs)
