MUCORMYCOSIS : A BLACK FUNGUS

 Doctors in India are concerned about an increasing number of potential fungal infection affecting either people who have COVID-19 or those who have recently recovered from the disease. The condition known as MUCORMYCOSIS has a high mortality rate and was present in India before the pandemic. Some experts attribute the fungal infections to an increased use of steroids to treat hospitalised patients. Another could be that , with hospital overwhelmed in this second wave of pandemic, many families are self medicating and applying oxygen therapy at home without the proper hygiene, expert say. What is mucormycosis? Black fungus is a serious but rare fungal infection caused by group of molds that live in environment called mucormycosis. Mucormycosis mainly affects people who have health problems or take medicine that lower the body's ability to fight germs and sickness . This disease can be fatal . It most commonly affects the sinuses or the lungs after inhaling fungal spores from the ai...

CORONA: THE BADLY SPREADING VIRUS

CORONA VIRUS    Corona virus disease (COVID -19) is an infectious disease caused by a newly discovered coronavirus. Most of the people infected with the COVID -19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease , diabetes, chronic respiratory disease and cancer are likely to develop serious illness. How does corona virus spread?  Expert believe the virus that causes COVID-19 spreads mainly from person to person . Droplet or aerosols- when an infected person coughs, sneezes or talks droplet or tiny particles called aerosols carry the virus into air from their nose or mouth.  Airborne transmission- research shows that the virus can live in the air for up to 3 hours. It can get into your lungs if someone who had it breaths out and you breath that air in. Surface transmission- when you touch surfaces that someone who has the vir...

NEW STRAINS OF CORONA VIRUS

Strains of Corona virus The corona virus at the root of COVID-19 is the newest known member of this family. At their core ,corona virus contain a genetic blue print called RNA , similar to DNA . The single stranded RNA acts as a molecular message that enables production of protein needed for other elements of the virus. Encapsulating the RNA genome is the viral envelope which protects the virus when it is outside of a host cell . This outer envelope is made from a layer of lipid ,a waxy barrier containing fat molecules. The bulbous projections seen on the outside of the corona virus are spike proteins (red orange). This fringe of proteins gives the virus its crown like appearance under the microscope from which the latin name corona derived.                             Multiple variants of the virus that causes COVID-19 are circulating globally. In collaboration with SARS -COV-2  Interagency Group (SIG) for SARS ...

New covid-19 Drug '2-DG'

'2DG'- Drug for Covid-19 patients What is '2-DG'  On monday, May 17 , DRDO (Defense Research Development Organization) released the first batch of the indigenously developed anti-Covid-19 drug, '2-DG' abbreviated as 2-deoxy-D-glucose. 2DG is an oral drug.   On May 1, The national drug regulator, Drug Controller General of India (DCGI) granted permission for the emergency use as an adjunct therapy in moderate to sever COVID-19 patients.  2-DG has been developed by INMAS (Institute of Nuclear Medicine and Allied Sciences)  and DRDO (Defense Research Development Organization) in collaboration with Hyderabad based pharma company, Dr. Reddy's laboratories.  How it Works?  The drug accumulates in virus infected cells and prevents the growth of the virus by stopping viral synthesis and energy production.  2-DG molecules helps patients to recover faster and reduces their dependence on supplemental Oxygen.   It's  selective accumulation in viral infec...

उत्परिवर्तन

  उत्परिवर्तन क्या है? किसी जीव के आनुवंशिक पदार्थ में अचानक परिवर्तन को  उत्परिवर्तन  कहा जाता  है। उत्परिवर्तन असंतत भिन्नता के स्रोत हैं। उत्परिवर्तन सबसे पहले  सेठ राइट  द्वारा देखा गया था  । वर्तमान में उत्परिवर्तन की आवृत्ति 1×10^(-6) है (1 सेल इन: 1 मिलियन - सेल)।  लेकिन यह भविष्य में प्रदूषण और ओजोन परत के विनाश के कारण बढ़ेगा।     कोरोना वायरस   में उत्परिवर्तन -                   कोरोना वायरस में म्यूटेशन धीमी है।  एचआईवी की तुलना में सार्स-सीओवी-2 बहुत धीरे-धीरे बदल रहा है।  उदाहरण के लिए, सेवर एक्यूट रेस्पिरेटरी सिंड्रोम (SARS) वायरस मनुष्यों में घूमने लगा, इसने एक प्रकार का उत्परिवर्तन विकसित किया जिसे विलोपन कहा जाता है जिसने शायद इसका प्रसार दिखाया हो।  उत्परिवर्तन के कारण - •  उत्परिवर्तन विशिष्ट रसायनों या विकिरण के संपर्क के कारण हो सकता है। •  अल्फा, बीटा, गामा और एक्स-रे भी उत्परिवर्तन का कारण बन सकते हैं। •    रसायन  ...

White Fungus Infection

White Fungus: A deadly Infection What is White Fungus?  White fungus is a fungal infection where there is form of whitish membrane or discharge caused by candida group of organism .

RED BLOOD CELLS

Red blood cell , also called erythrocyte . Red blood cells are the key of life.They are constantly traveling through your body , delivering oxygen and removing waste . If they didn't do their job , you would slowly die.  RBCs contain a protein called hemoglobin. Hemoglobin contain iron which makes it an excellent vehicle for transporting oxygen and carbon dioxide.    Internal structure   RBCs are considered cell, they lack a nucleus , nuclear DNA . RBCs therefore can't divide or replicate like other cells of the body . They also lack the components to express genes and synthesize protein .  Also read -  Endangered species How RBC  works? The red blood cell develop in bone marrow in several stages from a heamocytoblast , a multi potential cell in the mesenchyme , it becomes an erthroblast , during two to five days of development , the erthroblast gradually fills with hemoglobin and its nucleus and mitochondria disappear . In late stage the cell is calle...

MUTATION

  What is mutation? Sudden heritable change in genetic material of an organism is called as mutation. Mutation are source of discontinuous variation. Mutation was first observed by Seth Wright. Frequency of mutation at present is 1×10^(-6) (1cell in : 1 million - cell). But it will increase in future due to pollution and destruction of ozone layer.  Mutation in     Corona virus  -                  Mutation in corona virus is slow . Compared with HIV , SARS - COV - 2 is changing much more slowly . After Saver Acute Respiratory Syndrome (SARS) virus began circulating in humans ,for instance,it developed a kind of mutation called a deletion that might have showed its spread.  Causes of mutation - • Mutation can be caused by exposure to specific chemicals or radiation. • alfa , beta , gamma and X  - rays can also causes mutation . • Che mical mutation are more harmful than radiation because body is not prot...
