HIV/AIDS is a disease that weakens the immune system and leaves individuals susceptible to opportunistic infections and cancers. It is transmitted through contact with certain bodily fluids and has killed over 25 million people worldwide since 1981. While treatments can slow the progression of the virus, there is currently no known cure. The social stigma surrounding HIV/AIDS can be as destructive as the disease itself.

Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV). This condition progressively reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections and tumours. HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. This transmission can involve anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, breast feeding or other exposure to one of the above bodily fluids.
Genetic research indicates that HIV originated in west-central Africa during the late nineteenth or early twentieth century. AIDS was first recognized by the U.S. Centres for Disease Control and Prevention in 1981 and its cause, HIV, identified in the early 1980s. Although treatments for AIDS and HIV can slow the course of the disease, there is no known cure or vaccine. Antiretroviral treatment reduces both the mortality and the morbidity of HIV infection, but these drugs are expensive and routine access to antiretroviral medication is not available in all countries. Due to the difficulty in treating HIV infection, preventing infection is a key aim in controlling the AIDS pandemic, with health organizations promoting safe sex and needle-exchange programmes in attempts to slow the spread of the virus.
In the beginning, the U.S. Centres for Disease Control (CDC) did not have an official name for the disease, often referring to it by way of the diseases that were associated with it, for example, lymphadenopathy, the disease after which the discoverers of HIV originally named the virus. The earliest known positive identification of the HIV-1 virus comes from the Congo in 1959 and 1960 though genetic studies indicate that it passed into the human population from chimpanzees around fifty years earlier.
The HIV virus descends from the related simian immunodeficiency virus (SIV), which infects apes and monkeys in Africa. There is evidence that humans who participate in bush meat activities, commonly acquire SIV. To explain why HIV became epidemic, there are several theories, each invoking specific driving factors that may have promoted SIV, rapid transmission of SIV through unsterile injections, colonial abuses and unsafe smallpox vaccinations or prostitution and the concomitant high frequency of genital ulcer diseases (such as syphilis) in nascent colonial cities.

HIV/AIDS
Abstract
HIV is a virus that causes AIDS. The term in full stands for Human Immunodeficiency Virus. This virus has led to massive deaths globally with many more people being infected as well as being affected by the effects of the virus. In this paper, we shall describe the virus in depth, showing how it gets into a person's body, its causes and symptoms. We shall also discuss its prevalence and how it has affected people's lives. Most importantly, we shall discuss how a person can be treated after being infected with the virus. Finally, we shall study various preventative measures that can be used against the virus.
HIV Definition
The term HIV means Human Immunodeficiency Virus. This is a virus that makes the immune system of a person weak through destruction of vital cells that fight infection and diseases. To date, there is no existence of a cure in the United States nor in other parts of the world. Nevertheless, it is easy to prevent HIV infection through varying control measures. . Depending on different factors, some people are more prone to getting infected than others. Such factors include risky sexual behaviors, sex partners and environment (CDC, 2018).HIV is to a large extent spread through unsafe sex, blood contamination, needles, breastfeeding, and delivery and from a mother to her child during pregnancy.
AIDS Definition
Unlike HIV that is a virus, AIDS is a full-blown disease caused by HIV virus. Once a person's immune system becomes extremely weak, then he\she is said to have AIDS. At this moment, a person's immune system is not able to fight diseases or infection. There are certain illnesses and symptoms that develop as a result of a person contracting AIDS. This can also be described as the last HIV stage since at this moment the infection is highly advanced. If the symptoms of this disease are not controlled or treated, a person ends up losing life (Avert, 2017).
How a Person Get Infected with HIV and HIV Life-cycle
HIV attacks T- helper cells which are also known as CD4 cells. This are some forms of white cells. A person is able to have a strong immune system through CD4 cells being healthy because it's the only way they can be able to fight infections and diseases. It is not possible for HIV to reproduce or grow without being in T-helper cells. HIV makes many copies or reproduces while inside these cells. As a result of the reproduction, the immune system gets damaged which causes it to weak a person's natural immune system. The overall health of a person is the main determinant of how the HIV virus grows. Other determinants of HIV growth is how constant a person takes treatment and how early a person gets diagonalzed. If the antiretroviral treatment is taken correctly, then the immune system remains healthy hence pr.
HIV (Human Immunodeficiency Virus) infects cells of the immune system and destroys or impairs their function.
Infection progressive deterioration of the immune system breaking down the body's ability to fight out infections & diseases by opportunistic bacteria, viruses and fungi.
AIDS (Acquired Immune Deficiency Syndrome) refers to the most advanced stages of HIV infection and a collection of signs and symptoms caused by more than 20 opportunistic infections or related cancers.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
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

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

1. AIDS Acquired immune deficiency syndrome or acquired immunodeficiency syndrome ( AIDS or Aids ) is a collection of symptoms and infections resulting from the specific damage to the immune system caused by the human immunodeficiency virus (HIV) in humans. Beware of strong language- and image-material
2. HIV/AIDS is one of a number of killer diseases, such as, malaria, tuberculosis, cancer and heart disease. What is different about HIV/AIDS is that it impacts not only the physical health of individuals, but also their social identity and condition. The stigma and discrimination surrounding HIV/AIDS can be as destructive as the disease itself.
3.
4. The late stage of the condition leaves individuals susceptible to opportunistic infections and tumors. Although treatments for AIDS and HIV exist to decelerate the virus' progression, there is currently no known cure. HIV are transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. This transmission can come in the form of anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, or breastfeeding, or other exposure to one of the above bodily fluids.
5.
6. Most researchers believe that HIV originated in sub-Saharan Africa during the twentieth century; it is now a pandemic, with an estimated 38.6 million people now living with the disease worldwide. As of January 2006, the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO) estimate that AIDS has killed more than 25 million people since it was first recognized on June 5, 1981, making it one of the most destructive epidemics in recorded history.
7.
8. In 2005 alone, AIDS claimed an estimated 2.4–3.3 million lives , of which more than 570,000 were children . A third of these deaths are occurring in sub-Saharan Africa , retarding economic growth and destroying human capital. Antiretroviral treatment reduces both the mortality and the morbidity of HIV infection , but routine access to antiretroviral medication is not available in all countries. HIV/AIDS stigma is more severe than that associated with other life-threatening conditions and extends beyond the disease itself to providers and even volunteers involved with the care of people living with HIV .
10. WHO disease staging system for HIV infection and disease Stage I: HIV infection is asymptomatic and not categorized as AIDS Stage II: includes minor mucocutaneous manifestations and recurrent upper respiratory tract infections Stage III: includes unexplained chronic diarrhea for longer than a month, severe bacterial infections and pulmonary tuberculosis Stage IV: includes toxoplasmosis of the brain, candidacies of the esophagus, trachea, bronchi or lungs and Kaposi's sarcoma; these diseases are indicators of AIDS.
11.
12. Many people are unaware that they are infected with HIV . Less than 1% of the sexually active urban population in Africa has been tested, and this proportion is even lower in rural populations. Furthermore, only 0.5% of pregnant women attending urban health facilities are counseled, tested or receive their test results. Again, this proportion is even lower in rural health facilities. Therefore, donor blood and blood products used in medicine and medical research are screened for HIV.
13.
14. The symptoms of AIDS are primarily the result of conditions that do not normally develop in individuals with healthy immune systems. Most of these conditions are infections caused by bacteria, viruses , fungi and parasites that are normally controlled by the elements of the immune system that HIV damages . Opportunistic infections are common in people with AIDS. HIV affects nearly every organ system. People with AIDS also have an increased risk of developing various cancers such as Kaposi's sarcoma, cervical cancer and cancers of the immune system known as lymphomas.
15.
16. 1 december World AIDS Day is a day when people from around the world come together within a single effort.
17.
18. Lack of recognition of human rights not only causes unnecessary personal suffering and loss of dignity for people living with HIV or AIDS but it also contributes directly to the spread of the epidemic since it hinders the response… For example, when human rights are not respected, people are less likely to seek counselling, testing, treatment and support because it means facing discrimination, lack of confidentiality or other negative consequences. It also appears that the spread of HIV/AIDS is disproportionately high among groups that already suffer from a lack of human rights protection, and from social and economic discrimination, or that are marginalised by their legal status.
19.
20. Since the HIV/AIDS epidemic began, over 60 million people have been infected with HIV and more than 20 million have died of AIDS. Despite wide-ranging interventions to curtail its further spread and to mitigate the impact of its effects, there are around 16 000 new infections each day and at the crux of the epidemic are young people, accounting for over 50 % of this daily toll. That is why young people are, and must be, at the centre of action on HIV/AIDS.
21.
22. Those most likely to hold misconceptions about HIV transmission and to harbor HIV/AIDS stigma are less educated people and people with high levels of religiosity or conservative political ideology.
