Biochemistry involves studying the chemistry of living things
such as substances, compounds and processes. Biochemists combine the fields of
microbiology, cell biology, genetics, chemistry, cell biology, and physics in
their day-to-day work or experiments. They get into the most, minute
characteristics of organisms, and their biological processes. They may be
identifying the way in which DNA, which carries the genetic information, is

Breast Cancer: Introduction, pathophysiology and diagnosis
Breast Cancer: Where It Starts
Unfortunately, signs
of breast cancer are rarely visible from the surface of the skin. Breast
self-exams should be done regularly to detect physically substantial lumps
under the skin. But even self-exams may miss some cases. By moving the slide
from left to right, you will see where (in most cases) breast cancer develops:
deep down in the inner structures of the breast, within the ducts.
Cellular Abnormalities & Cancer
Cancer begins deep
down in the body, at the cellular level. Cells are the basic building

The Three Major Stress Hormones: Adrenaline, Cortisol, Norepinephrine
Thanks to the work of our sympathetic
nervous system, the "fight or flight" system that takes over when
we're stressed, when you see your boss's name in your inbox late at night, your
body reacts like there's a lion on the loose.
Behind the wide range of both physical
and mental reactions to stress are a number of hormones that are in charge of
adding fuel to the fire.
Adrenaline
What It Is: Commonly known
as the fight or flight hormone, it is produced by the adrenal
glands after receiving a message from the brain that a stressful situation has
presented itself.
What It Does: Adrenaline,
along with norepinephrine (more on that below), is largely

Diabetes could be cured after scientists discovered that toxic clumps of a hormone stop cells producing insulin.
Scientists at Manchester University have found that both Type 1 and Type 2 diabetes are driven by the same underlying mechanism.

Ebola Virus Outbreak in west Africa and its Risk Assessment
The current Ebola Virus outbreak began in Guinea in December
2013. This outbreak now involves transmission in Guinea, Liberia, Nigeria, and
Sierra Leone. As of 4 August 2014, countries have reported 1 711 cases (1 070
confirmed, 436 probable, 205 suspect), including 932 deaths. This is currently
the largest EVD outbreak ever recorded. And on 8 August 2014, WHO declared the
Ebola outbreak in West Africa a Public Health Emergency of International
Concern.
Epidemiological facts and experience
- The incubation period of Ebola virus disease (EVD) varies from 2 to 21 days. Person-to-person transmission by means of direct contact with infected persons or their body fluids/secretions is considered the principal mode of transmission. In a household study, secondary transmission took
