Coronavirus :- A Pandemic

      Coronavirus :- A Pandemic


Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.

           They  are a group of related RNA VIRUSES that cause diseases in mammals and birds.

             

        Illustration of Above figure

  Red: spike proteins (S)

  Grey: lipid bilayer envelope

  Yellow: envelope proteins (E)

  Orange: membrane proteins (M)

                         Virus Classification

(unranked): Virus

Realm: Riboviria

Kingdom: Orthornavirae

Phylum: Pisuviricota

Class:Pisinoviricetes

Order:Nidovirales

Family:Coronaviridae

Subfamily:Orthocoronaviridae

       -  They have characteristic club-shaoped spikes that project from their surface, which in electron micrographs create an image reminiscent of the solar corona, from which their name derives.

         -  Symptoms -


-Fever or chills

-Cough

-Shortness of breath or difficulty breathing

-Fatigue

-Muscle or body aches

-Headache

-New loss of taste or smell

-Sore throat.     

-Congestion or runny nose

-Nausea or vomiting

-Diarrhea 

   -  Prevention & Treatment -


A number of vaccines using different methods have been developed against human coronavirus SARS-CoV-2. Antiviral targets against human coronaviruses have also been identified such as viral proteases, polymerases, and entry proteins. Drugs are in development which target these proteins and the different steps of viral replication.


Vaccines are available for animal coronaviruses IBV, TGEV, and Canine CoV, although their effectiveness is limited. In the case of outbreaks of highly contagious animal coronaviruses, such as PEDV, measures such as destruction of entire herds of pigs may be used to prevent transmission to other herds.

Cell Death :- Apoptosis

Image
              -  Apoptosis -                              Apoptosis is a pathway of cell Death in which cell activates enzymes that degrades the cell's own nuclear DNA and nuclear and cytoplasmic proteins. - It is a programmed cell Death.                  | Causes of Cell Death |  A. Physiological condition  - Programmed destruction of cell during embryogenesis  - Involution of hormone-dependent tissues upon hormonew withdrawl . Eg. Endometrial cell breakdown during menstrual cycle.  - Elimination of potentially harmful self-reactive lymphocytes. - Death of host cell that have served a useful purposes . Eg. Neutrophils in an acute inflammatory process, Lymphocytes at the end of an immune response . B. Pathological condition -Cell death resulting from damaged of DNA due to radiation cytotoxic drugs, hypoxia or ...

Tumor

Image
             -  Tumor - Tumor  is a mass of tissue that's formed by an accumulation of abnormal cells. It occurs when cells divide and grow excessively in the body. A tumor may be of two types :- a. Benign and b. Malignant  Here are few differences that we should know about these two tumors as most of people get confused between them                 Benign Tumor v/s Malignant  Features a. Boundary;-encapsulated  and well circumscribed in Benign but poorly circumscribed or irregular in Malignant b. Surrounding Tissues;- often compressed in Benign but invaded in Malignant   c. Size ;- usually small in Benign but usually large in Malignant d. Pleomorphism;- Usually not present in Benign but often present in Malignant   e. Nucleus/cytoplasm ratio;- Normal (1:4 to 1:6 ) in Benign but high up to 1:1 in Malignant   f. Hyperchromatism;- Absent in Benign but present in M...
