What we can learn from dogs?

...s and differences in disease patterns in different mammals - and it sure has a bright future. We share many of our genes with our primate cousins - yet they rarely get cancer. Dogs and humans are similar in many ways, but dogs do not suffer from high blood pressure, even when they have kidney disease.// Pr...

Caffeine can induce epilepsy in newborns

...ment of epileptic discharges in cells from newborn mammals that have been briefly starved of oxygen. A research team from the Institut National De La Santé in France examined cells from the hippocampus, a part of the brain that is thought to control memory.They subjected the cells to the same level of caffe...

Mental growth in babies at risk

...rtex took longer than normal to mature. Since all mammals share similar basic patterns of brain development they are likely to apply to humans. Further experiments showed that rats whose brain development was held back were able to improve once they left the noisy environment. Hence researchers emphasise th...

Gene is related to premature ageing disease

... of the major genes that lead to the physiology of mammals and reside in mammalian cell nucleus. Fibroblasts from the individual with the disease have severe abnormalities in the nuclear envelope structure. Scientists have not only identified the gene responsible for the progeria syndrome, but they have de...

Sleep Not Critical For Early Brain Development Of Baby Dolphins

...8 hours. However, it is different with some of the mammals living in the sea. It has been reported in Nature ...leep is critical to early development. Most of the mammals so far studied sleep and rest after birth and only gradually decrease their sleep requirements as th...

Scientists Developed Map For Brain Molecular Communities

...k model of a molecular community in brain cells of mammals in order to predict the targets and side effects of new drugs. Researchers from Mount Sinai School // of Medicine have reported their findings in the latest issue of journal Science. The study analyzes how molecular communities are organized and h...

Have You Ever Wondered How We Perceive Different Sounds?

...rds, are capable of re-growing hair cells. However mammals lack the ability to naturally regenerate hair cells. Thus individuals born with improperly developed hair cells, or those who lose them through trauma, disease, environmental factors or aging, cannot regain their hearing. Optimistic results have be...

Stem Cells To Repair Heart Damage

...ould also be successfully transplanted into larger mammals to regenerate damaged heart cells. In their study, 9 sheep given transplanted mouse embryonic stem cells had healthier heart tissue after one month compared with 9 sheep that did not receive stem-cell transplantation (the control group). This strengt...

Acute Toxicity Of Nano-Scale Zinc Powder: Severe Renal Damage And Anemia

...s. Although zinc is an essential metal needed by mammals and commonly found in nutritional supplements, acute, high-dose oral exposure to zinc and its compounds generally results in gastrointestinal damage, with symptoms including nausea, vomiting, abdominal cramps, and diarrhea. According to the U.S. Depa...

Fertility Treatment Offered During Summer Has Better Chances For Success

... observation may be evolutionary; it is known that mammals are more likely to conceive during the summer because it means their offspring will be born in the spring, when food is more plentiful, the weather warmer and they have a higher chance of survival. The findings on this study have valuable clinical ...

More Lizards, Including Pets, Found Venomous

... punch by monitor lizards to their prey like small mammals and lizards. It stops blood clotting, rapidly drops blood pressure and heightens the feeling of bite pain. They assume that lizard venom may have gone unnoticed for so long because it is not fatal, and yet, it may help lizards catch prey. The res...

Decoding the Fungi Genome Will Save Millions of Lives.

...e proteins, a similar percentage to that shared by mammals and fish which diverged 450 million years ago. They also differ considerably in genome size, with Aspergillus oryzae being 31 percent bigger than Aspergillus fumigatus and 24 percent bigger than Aspergillus nidulans.

Caffeine: Stimulates Sexual Behaviour in Females

...they wanted to show the effects of caffeine on the mammals (humans) especially the sexual motivation in the females. But in case of humans most of them drink coffee which contributes to a moderate amount in their body and hence the effects of caffeine cannot be well analyzed. Whereas in case of rats they are...

Hh Signaling May Play Role In Fat Formation

The Hh pathway drugs may also be useful for treating conditions like diabetes, obesity, osteoporosis, and lipodystrophy, according to the research. Common traits which are ...

Early Man Was A Prey Rather Than A Predator

... and Human Evolution," Sussman contends that early mammals and man did not evolve as predators but rather as prey for wild dogs and cats, hyenas, eagles and crocodiles. “Our intelligence, cooperation and many other features we have as modern humans developed from our attempts to out-smart the predator," he s...

Diseases in Marine Animals Could Portend Unhealthy Prognosis for Humans

Aggression And Fatherly Behavior: Men Have It In Their Genes

...s been known for a long time that maleness in most mammals relates to aggressive behavior and a less nurturing tendency, compared to females. Humans are no exception // to the above fact. The male sex hormones, more specifically testosterone has been blamed for such behavior. It has now been found that sex c...
