Germ cell testicular cancer incidence
Testicular cancer is not your normal malignancy. A few cancers occur in children, while most occur in older people. However, hardly any occur specifically in young adults. Testicular cancer is one. Incidence rises rapidly in the teen
Barley meiosis: The importance of sticking together
The process of crop improvement is based on promoting the exchange of genetic material by making crosses between two complementary parent plants followed by identifying progenies that perform better than the original parents. The genetic exchange occurs
Stress and pain – subgroups, mechanisms and treatment outcomes

Tropical theileriosis, caused by Theileriaannulata, is the most economically important disease of domestic buffaloes and causing major losses in livestock production in tropical and subtropical regions. Sialic acids (SA), a family of over 40 neuraminic acid derivatives,
An oblique approach to the lumbar spine: what we know so far
As people get older, lower back and leg pain is a common and often debilitating problem, preventing simple tasks including walking. Unfortunately it is unavoidable because of simple wear-and-tear of the discs and joints that make up
Non-invasive brain stimulation: how reliably can we change your mind?
Non-invasive brain stimulation is becoming increasingly popular within scientific research. This is because it has the ability to painlessly influence targeted regions of the brain, without the side effects associated with many medications. At first glance, the
Activation tagged mutant resource of rice – a gold mine for agronomic applications
Insertional mutagenesis is a technology in which a segment of DNA, about which the investigator has complete information for its tracking, is introduced into the plant genome. These known DNA fragments can be elements such as transposons
The clockwork behind depression
Globally, an estimated 350 million people of all ages suffer from depression and the number is increasing. Currently, we don’t know exactly what causes depression. However, what we do know is that depression and the circadian rhythm
