Cholesterol-lowering drugs may fight infectious disease

#zrodlo

Scientists found a gene variant that affects cholesterol levels also could increase the risk of contracting typhoid fever. A common cholesterol-lowering drug could protect animal models against Salmonella Typhi, the culprit behind the potentially deadly infection. The findings give insight into the mechanisms that govern human susceptibility to infectious disease and point to possible avenues to protect against pathogens -- like Salmonella or Ebola -- whose entry into host cells is regulated by cholesterol.

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs.

#zrodlo

For the first time, researchers are using proteomics to examine proteins and peptides in saliva in order to accurately detect exposure to Zika virus. With 70 countries and territories reporting evidence of mosquito-borne Zika virus transmission, there is an increased need for a rapid and effective test for the virus. This study offers a new, quicker and more cost-effective way to test for the virus.

Nectar, the high-energy 'honey' produced by flowers, might be a brilliant distraction technique to help protect a flower's reproductive parts, according to new research. Rather than merely providing a 'come-on' to bees and other insects to attract them to pollinate the flower, nectar could be playing a much more subtle and entrancing role.

#zrodlo

New research has discovered a potential means to trigger damaged heart cells to self-heal. The discovery could lead to groundbreaking forms of treatment for heart diseases. For the first time, researchers have identified a long non-coding ribonucleic acid (ncRNA) that regulates genes controlling the ability of heart cells to undergo repair or regeneration. This novel RNA, called 'Singheart,' may be targeted for treating heart failure in the future.
