Classic hydrogenation catalyst installs multiple stereocentres one by one to create small amino acid rings as single enantiomers. A rhodium catalyst that can walk around a macrocyclic ring and create multiple stereocentres in a row could change the way chemists make cyclic peptides. The unusual mechanism was discovered in a hydrogenation catalyst that has been studied for half a century.

Eczema is a condition in which patches of skin become itchy, red, inflamed, rough and cracked. The term eczema is specifically used to talk about its most common i.e. atopic dermatitis where “atopic” refers to a group of diseases which also involves the immune system and “dermatitis” refers to inflammation of the skin. It is not a contagious condition. Symptoms may vary depending upon the factors like age and can be triggered through environmental factors like pollen and smoke.
According to a new study, researchers developed a new technology that detects radiation from the sun in real time and immediately predicts subsequent health risks could protect astronauts on future deep-space missions.
Researchers say a study designed to see if reducing the amount of anesthesia reduces the risk of postoperative delirium in older patients surprisingly found that lighter sedation failed to do so in severely ill people undergoing hip fracture repair. The study was published in JAMA Surgery, underscores the need for tailoring the amount and type of anesthesia to each individual's overall health status.
A common feature in palliative care is reduced oral intake, and patients may require additional support to ensure they receive adequate nutrition and hydration. As the disease progresses, deterioration in symptoms particularly those involving fatigue, muscular weakness and dysphagia can make eating more difficult, and this can impact patients not only physically but also psychologically.
According to a study, researchers examined antipsychotic-treated patients with severe mental illnesses (SMI) have a high prevalence of diabetes and prediabetes.The study was published recently in Diabetes Care.
Researchers have all heard of the link between eating sh*tty foods and cancer. The study investigated whether or not regularly eating dinner before 9 pm, or at least two hours before going to bed, could significantly lower someone’s risk of developing cancer. To find this out, researchers explored the nightly habits of a group of 1,826 breast and prostate cancer patients and compared them to 2,193 healthy individuals.
Disruptions In Circadian Rhythm
Researchers think it could be to do with disruptions to the circadian rhythm. The results indicated that those who recalled regularly eating dinner before 9 pm or at least two hours before going to bed had a 26% lower risk of developing prostate cancer and a 16% lower risk of developing breast cancer.
Needless to say, meal timing had a significant effect on the cancer risk factor of those participating. The study was published in the International Journal of Cancer.
Fighting to stay alive, the only thing they could not wake up for weeks. Julissa is a hantavirus survivor. These are viruses that humans acquire through contact with rodent urine, saliva or feces. Jolissa likely caught the virus when she cleaned out the family trailer in the spring for a camping trip. What began as extreme fatigue that she associated with being a new mom progressed into total exhaustion, nausea, and fever.
Researchers wanted to know the significance of that variability and whether portions of that variability might be due to changes in an individual's focus of attention. Take a look at your favorite mug; it probably looks the same as it always has, but your neurons may not think so. Neurons are firing in response to the visual stimuli they see but they don't fire in exactly the same way every time. The study published in Nature Communications.
The company behind Oticon Opn™, the world’s first internet-connected hearing aid, announces its smallest hearing aid to date featuring Oticon’s revolutionary 360° open sound experience. Only around 40% of people in the UK who need hearing aids have them.
A common deciding factor for many people in choosing a hearing aid is aesthetics. Many would still prefer not to have their hearing aid noticed at all, which is why pioneering hearing aid provider, Oticon, has added an invisible hearing aid to their world renowned range of Oticon Opn™ hearing aids.
Researchers investigate mortality due to trauma and non-trauma at the emergency department of Rajiv Gandhi Government General Hospital (RGGGH) has dropped. Accident and emergency protocols that were rolled out on a pilot basis in January 2018 have streamlined emergency care, reducing delay in attending to patients, through triaging and prompt initiation of investigations and treatment.
New research suggests that depression in women may affect their children's stress and physical well-being throughout life. Researchers followed 125 children from birth to 10 years. At 10 years, mothers' and children's cortisol (CT) and secretory immunoglobulin (s-IgA), markers of stress and the immune system were measured, mother-child interaction was observed, mothers and children underwent psychiatric diagnoses, and children's externalizing and internalizing symptoms were reported. The study was published in Depression & Anxiety.
