Monkeypox is very difficult to catch from someone carrying the infection and is mostly caught from infected wild animals in west of central Africa. 

The initial symptoms include a high temperature, headache, muscle aches, backache, swollen glands, shivering and exhaustion. A rash will usually appear after a few days, beginning on the face and then spreading to other parts of the body.

Sudden infant death syndrome, or SIDS, usually happens when infants die in their sleep without any particular reason. Researchers in Australia say they’ve found why infants die from SIDS.

In the latest study, researchers found that infants who died from SIDS had lower levels of an enzyme known as Butyrylcholinesterase (BChE). This enzyme is thought by scientists to help regulate pathways in the brain which drive a person’s breathing, confirming what scientists had originally hypothesized. 

Bioprinting is an additive manufacturing process similar to 3D printing – it uses a digital file as a blueprint to print an object layer by layer. But unlike 3D printing, bioprinters print with cells and biomaterials, creating organ-like structures that let living cells multiply.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disease characterized by profound fatigue, sleep abnormalities, pain, and other symptoms that are made worse by exertion.

This audiovisual describes in detail the life cycle of the Onchocerca volvulus and its role in causing blindness in Ghana. Clinical examples of persons afflicted with this disease are shown to elucidate the effects of the disease. According to the presentation, the disease is transmitted by the bite of black flies of the family Simuliidae. The method by which the flies acquire the organism is carefully outlined, as is the process by which the infective larvae enter the wound and develop into male and female worms, which mate and cause a tissue reaction in man. This reaction produces fibrous nodules which often appear externally as lumps. If ocular invasion occurs, blindness can result. Treatment of the disease by surgical removal of the nodules or by administration of the drug diethylcarbamazine is discussed. Measures to control the breeding grounds of the flies with DDT are also noted.

Mice who received mixture of four reprogramming molecules— Oct4, Sox2, Klf4 and cMyc, also known as “Yamanaka factors”—  for several months resembled younger animals in many ways, with their skin and kidneys, in particular, showing signs of rejuvenation.
