Rabies is a fatal viral disease that affects the central nervous system. It is caused by a rhabdovirus that is most commonly transmitted to humans via bites from rabid bats, foxes, skunks, and raccoons in North America, and dogs worldwide. There is no established treatment for rabies once symptoms develop, so prevention through vaccination is important.

Viruses 1
Viruses are obligate intracellular parasites that infect all living organisms. They possess either DNA or RNA and lack organelles like cell membranes and ribosomes. Viruses come in a variety of shapes and sizes, with the smallest being 20nm and largest 400nm. They enter host cells and hijack the cell's machinery to replicate their genome and proteins. Viruses can undergo lytic or lysogenic replication cycles. Laboratory diagnosis of viral infections involves direct visualization of viruses, detection of antigens and antibodies, and molecular methods like PCR to detect viral genes.

Micro bio(rhebovirus)
Rabies is a viral disease caused by the rabies virus, which infects the central nervous system. It is typically transmitted through bites from infected animals. The rabies virus is bullet-shaped, enveloped, and contains a single-stranded RNA genome. It is susceptible to various disinfectants but can survive for weeks when stabilized by glycerol. The glycoprotein on the virus surface induces protective antibodies. Following transmission, the virus spreads from the peripheral nerves to the central nervous system, causing encephalitis. Diagnosis involves detecting viral antigen in biopsy samples. Post-exposure treatment consists of wound cleansing, rabies vaccinations, and potentially hyperimmune serum.

Viruses are acellular infectious agents that contain nucleic acids surrounded by protein coats. They are obligate parasites that do not carry out metabolism and lack organelles and ribosomes. Viruses come in various structures like helical, icosahedral, enveloped, and more complex forms. They replicate inside host cells by attaching to receptors, penetrating the cell, uncoating their genetic material, synthesizing new viral components, assembling new viral particles, and releasing particles to infect new cells. Viruses are classified into groups based on their nucleic acids, structures, and replication mechanisms. DNA viruses like herpesvirus contain double-stranded DNA and replicate in the nucleus, while RNA viruses have single-stranded genomes

adenovirus powerpoint.ppt
Adenoviruses are medium sized non-enveloped DNA viruses that commonly cause respiratory, eye, intestinal, and urinary tract infections in humans and animals. They are classified into subgroups A through F based on antigenic and genomic properties. Adenoviruses cause localized infection but can cause generalized infection in immunocompromised patients. While there is no highly effective antiviral treatment, adenoviruses have potential as vectors for vaccination and gene therapy by genetically altering them to code for specific antigens or proteins without producing infectious viral offspring.
Animal viruses
Animal viruses are self replicating, intracellular parasites that completely rely on host animal cell for reproduction. They use the host's cellular components to replicate, then leaves the host cell to infect other cells.

This document discusses the classification of viruses. It describes that viruses can be classified based on their nucleic acid composition (DNA or RNA), whether they are enveloped or not, and the disease they cause. It provides examples of virus families under each classification type. The document also discusses several virus classification systems used historically and currently, including the Baltimore classification system which is favored by molecular biologists as it groups viruses based on their replication strategies.
Rhabdo Virus.pptx
Rhabdoviruses are enveloped viruses with bullet-shaped particles that contain single-stranded RNA. They replicate by entering host cells and using their RNA polymerase to transcribe and replicate their genome. New virus particles then bud from the host cell. Rhabdoviruses can infect many species and are transmitted by arthropods or bites. Rabies virus causes fatal neurological disease in humans and other mammals by traveling along nerves to the brain. It evades immunity and commonly causes fear of water, paralysis, and death from respiratory failure. Diagnosis involves clinical evaluation, exposure history, and fluorescent antibody or PCR testing of brain or saliva samples.
SMALL POX A DEAD DISEASE
Smallpox was declared eradicated globally in 1980 by the WHO. It was caused by the variola virus and was highly contagious and often fatal without vaccination. Edward Jenner developed the smallpox vaccine in 1796 by inoculating people with cowpox, conferring cross-immunity. Mass vaccination campaigns using vaccinia virus led to smallpox eradication. The last known natural case was in Somalia in 1977.

MHC.pptx
The major histocompatibility complex (MHC) is a set of surface proteins located on nucleated cells that plays an important role in distinguishing self from non-self and antigen presentation. There are two types of MHC molecules: class I MHC molecules present antigens to cytotoxic T cells on all nucleated cells, while class II MHC molecules present antigens to helper T cells and are found only on antigen-presenting cells. Both MHC classes consist of a transmembrane alpha chain and beta chain that form a peptide-binding groove to load and present antigen peptides. MHC molecules allow the immune system to recognize foreign substances so the body's immune response can be triggered.
Human herpesviruses.pdf
This document summarizes several human herpesviruses:
1) Herpes simplex virus types 1 and 2 which can cause oral and genital lesions respectively and establish latency in nerve ganglia.
2) Varicella zoster virus which causes chickenpox and shingles and establishes latency in neurons.
3) Epstein-Barr virus which infects B cells and causes mononucleosis and some cancers by immortalizing B cells.
4) Cytomegalovirus which establishes latency in mononuclear cells and is a common cause of in utero infection in the US.
communicable disease .pdf
A communicable disease is caused by pathogens that can be transmitted between humans and animals. Common pathogens include viruses, bacteria, and fungi. Communicable diseases spread through various routes such as physical contact, airborne droplets, contaminated fluids or foods, or bites from insects or animals. Factors that influence the transmission of communicable diseases include the infectious agent, the route of exit from the host, the mode of transmission, the route of entry into a new host, and characteristics of the susceptible host. Communicable diseases have historically been a major cause of death but advances in public health have helped reduce their spread.
Diuretics .pdf
This document summarizes different types of diuretic drugs, including their mechanisms of action, indications for use, and potential adverse effects. It discusses 5 main classes of diuretics: 1) acetazolamide, which blocks carbonic anhydrase and decreases water resorption, 2) loop diuretics like furosemide that inhibit the NKCC2 pump and promote high volume diuresis, 3) mannitol, an osmotic diuretic that works in the proximal tubule, 4) thiazide and thiazide-like diuretics that inhibit sodium resorption in the distal tubule, and 5) potassium-sparing diuretics like spironolactone
Antigens and MHC
Antigens are foreign molecules recognized by the immune system that can bind to antigen-specific receptors on antibodies and T cells. An immunogen is an antigen that induces an immune response by binding to B-cell or T-cell receptors, while a hapten is too small on its own but can become immunogenic when attached to a carrier protein. Epitopes are the specific parts of antigens that are recognized by the immune system. Exogenous antigens come from outside the body and endogenous antigens are generated inside cells.

This document provides guidance on performing a comprehensive health history and physical examination. It outlines the key components of the health history, including the present illness, past medical history, family history, social history, and review of systems. It also describes the subjective and objective components. For the physical exam, it recommends examining the patient systematically from head to toe, using appropriate lighting, positioning, and techniques. It emphasizes taking vital signs, performing a general survey, and inspecting each body system. The goal is to obtain relevant health information through the history and physical exam to aid clinical decision making.
Immune Organs - organs of the immune system and immune cells .pdf
The tissues of the immune system consist of primary and secondary lymphoid organs. Primary organs include the thymus and bone marrow, where T and B cells mature. Secondary organs include the spleen, lymph nodes, and mucosal tissues, where immune cells are activated. Mature T cells proliferate and migrate to sites of infection, while mature B cells give rise to plasma cells and memory B cells upon activation. The immune system tissues work together to recognize pathogens and mount targeted responses through cellular and humoral immunity.
Red Blood cell and Bleeding Disorders.pdf
Anemia is a decreased level of red blood cells or hemoglobin in the blood, causing hypoxia in tissues. It is usually diagnosed based on decreased hematocrit and hemoglobin levels. There are three main types of anemia characterized by red blood cell size: normocytic, microcytic, and macrocytic. Microcytic anemia is caused by disorders of hemoglobin synthesis or iron deficiency, while macrocytic anemia results from bone marrow abnormalities. Symptoms of anemia include paleness of the skin, eyes, weakness, and fatigue. Anemia can be caused by blood loss, disorders of red blood cell production or destruction, or nutritional deficiencies such as iron or vitamin B12/folate.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Ageing, the Elderly, Gerontology and Public Health

Rabies Virus.pptx
- 2. RABIES VIRUS • Rabies; is a fatal but preventable viral disease. • Affects the central nervous system. • most common reservoirs; In Canada and USA: bats, foxes, skunks and raccoons. • most common reservoirs; In worldwide, mostly dogs • Negri bodies; is abnormalities in the neurons.
- 4. CHARACTERISTICS OF RABIES VIRUS • It is Family Rhabdoviridae • Linear • Single-stranded RNA • Negative sense RNA • Genome Replicate in cytoplasm • Non segmented
- 5. TRANSMISSION • The bite and virus-containing saliva of an infected host • Contamination of mucous membranes (i.e., eyes, nose, mouth) • Aerosol transmission • Corneal transplantations
- 7. DIAGNOSIS • 1. Detection of antigen by taking skin biopsy using immunofluorescence • 2. virus isolation from saliva & other secretions. • 3. CSF analysis and CT scan • 4. ELISA • 5. RT-PCR; (for rabies RNA in CNS (most sensitive method to detect rabies) • 6. DFA testing ( for corneal epithelial cells) • 7. microscopic examination of the CNS reveals Negri bodies
- 9. TREATMENT • No established treatment for rabies. • Recent treatment failures of antiviral therapy,ketamine, and therapeutic coma-milwaukee protocol • Expert opinion to be sought before any experimental therapy • A palliative approach may be appropriate for some patients.
