How many human researches guinea pig uses in 2018

YOU KNOW ?

Guinea pig biological  similar to human beings, which make them use in many field of human researches.
Guinea pig tissue and organs are extensively use in research  to develope  new medicine. 
LIKE - Beta blocker  to treat  high blood pressure and intestinal ulcers
Anti- nausea drug  consist (naturally occurring pain killer substance) enkephalins.

USES-
IN ALLERGIES AND RESPIRATORY DISEASES-
 guinea pig airways are sensitive to allergence so it has been  widely use in asthma studies .
 The inhaled medications that the mainstays  of asthma treatment ( orally active- drug) montilukast, also use to treat a vaccine  against anthrax,recent new medicine  to treat drug  resistant tuberculosis. 
IN INFECTIOUSDISEASES-
Sensitivity  of guinea  pigs regarding  some infectious  diseases  are similar to immune difference  system  of humans , 
LIKE-  mycobecteriam tuberculous  and lectospira  icteroids .

IN HEARING-
The structure of guinea pigs ears similar to that of human, means  hearing  range are also similar, 
Hair cells are the sensory  cell of the auditory  system, these cells don't re- grow when damage, so first successful  attampt  to regenerate  hair cell in the inner ear of a mammals , announced  in 2003 ,achieved in guinea  pigs.

IN NUTRITIONAL RESEARCH-
Guinea pigs requiring vit C, folic acid, thiamine,  argenine, & potassium in their  diet. They also carried most of their  plasma cholesterol  in low density  protein, which make them useful in nutrition  studies.

IN SAFETY TESTING-
The long gestration  period 59- 72 days, and mature nervous system  at birth means that guinea pigs are important in safety testing, particularly  to prevent  birth defence. However, similar to their immune system, their skin is more sensitive, so guinea pig are widespread use for allergic skin reactions.

What is snake venom and how its use as medicine

SNAKE VENOM USE AS A MEDICINE , Snake venom is highly  modified  parotid salivary gland secretion that secrets zootoxines. Venoms contain more than 20 different  compounds, mostly proteins, polypeptide, enzymes, and various other substances with toxins and other lethal  proterties serve  to immobilize and digestion of prey animal and defence against threats. SIX  MAZER MEDICAL  USES  FOR THE SNAKE  VENOM: 1) TREATING CANCER -   venom  from  rattlesnake contain a chemical  called crotoxin, it only work on particular kinds of cell (blood and muscles). Research Harnessed  the unique  combination  of targeting  and toxicity  in crotoxin to creat  a cancer treatment, called CB24. 2) REDUCE  BLOOD PRESSURE-  The venom  of the Brazilian  pitviper contain a protein that disrupt  the angiotensin - converting  enzyme (ACE), which rises blood pressu...

What are the gene therapies uses to treat cancer

                                              What  genes are Genes are coded massages that tell cells how to make proteins, proteins are the molecules that control the way cells behave. Our genes decide what we look like and how our body works. Genes are made of DNA and grouped togather to make chromosomes, they are in the nucleus of the cell. The nucleus  is the cell's control  centre. How the cell become cancerous   Cancerous cells are different  from the normal cells, they have faults or mutation in several of there genes which make them divide too often and form a tumor. The genes that are damaged might be: • Genes that encourage the cell to multiple   ( know as oncogenes) • Genes that stop the cell multiplying               ( tumour suppressor  gene) • Genes that r...

How we can convert liver cell in to nerve cell overview in 2018

YES, YOU KNOW ABOUT LEAPFROGGING ? Recent scientists developed  a method by which transmuting exsisting cells, into a totally new form .  This important discovery could help in generating essential cell in an ailing patient or cancerous agents into benign cells. RESEARCHERS - Stanford university  of medicine, In the laboratory  they have been directaly transformed fully matured mice liver cell into a nerve cell, this process was accomplished  by introduction of just three genes didn't required cells to first inter a pluripotent state  PROCESS-  GENE EXPRESSION FALLOWED WITH TRANSDIFFERENTIATION TECHNIQUES.   Hepatocytes arise from one of three classes of embryonic tissue called the endodermal; neurons from the ectoderms, accomplish  the transformation of hepatocytes, researchers  used a virus to introduce the three genes: Brn2, Ascl1, Myt1l. The hepatocytes  began to exhibit neuronal Characteristics  with...
