Exposure Of Spaceradiation Health Risk For Astronauts

Researchers examined the space radiation environment and the risk it poses to long-duration astronauts remains limited. There is a disparity between research results and observed empirical effects seen in human astronaut crews, likely due to the numerous factors that limit terrestrial simulation of the complex space environment and extrapolation of human clinical consequences from varied animal models.

Given the intended future of human spaceflight, with efforts now to rapidly expand capabilities for human missions to the moon and Mars, there is a pressing need to improve upon the understanding of the space radiation risk, predict likely clinical outcomes of interplanetary radiation exposure, and develop appropriate and effective mitigation strategies for future missions. 

Structure And Functions Of Cornea And Ocular Surface

Important functions of the cornea in the eye include protecting the structures inside the eye, contributing to the refractive power of the eye, and focusing light rays on the retina with minimum scatter and optical degradation. Considerable advances have taken place in understanding the organization of collagen in the corneal stroma and its clinical significance. In this review, the structure and function of various components of the cornea and ocular surface are presented.

Hidden Signals In RNAs That Regulate Protein Synthesis

Researchers have known that RNA encodes instructions to make proteins. The building blocks that comprise RNA-; A, U, C, and Gs-; form a blueprint for the protein-making machinery in cells. To make proteins, the machinery latches on RNA at one end and then scans along the RNA until it reaches an AUG string, which is the signal to start translating the genetic code into a protein. The study was published in Nature.

Super-Resolution Imaging Tissue Of Alzheimer’s Disease

A study developed super-resolution nanoscope.,The device not only presents a 3D view of the molecules in the brain, but it does so at a resolution ten times higher than anything that has gone before. It is hoped that this new imaging technique will offer vital insight into the progression of the disease and lead to new treatments.

Tackling Alzheimer’s disease is a multifaceted issue, but among the biggest obstacles to overcome is not being able to see the origins of the condition. Already, there is a change as a result of the instrument. Scientists at Indiana University have used it to understand better the plaques that form in the brain of patients with Alzheimer’s. They were able to pinpoint characteristics with the potential to be the cause of the damage.

Association Between Regional Anesthesia And Postoperative Pain Relief

Researchers explore the evolution of regional anesthesia and the impact of technology on its development. Since the first general anesthesia (GA), anesthesia has seen a rapid evolution. In tandem with advances in pharmacology, anesthesia techniques were developed to facilitate surgical procedures and to increase patient safety.

Besides GA, regional anesthesia (RA) was introduced in the late 19th century when K. Koller used cocaine as a local anesthetic and W. Halsted performed the first peripheral nerve block (PNB) by infiltrating a local anesthetic (LA) solution around the nerve, making a transmission for sensation and pain impossible.

Hospice Care For Pain-Free Healing

The pain of illnesses was too much for people to handle. This is when he sought palliative care. Palliative care is focused on providing relief from the symptoms and stress of a serious illness. The goal is to improve the quality of life for both the patient and the family. It is a comprehensive symptom management programme which treats total pain.

ICU Patient's Relatives Worried About The Medical Staff

A new study examine many family members of intensive care unit (ICU) patients are reluctant to tell medical staff of worries about their loved one's care. Speaking up is a key component of safety culture, yet our study the first to our knowledge to address this issue revealed substantial challenges for patients and families speaking up during an ICU stay.

They surveyed 105 families of patients admitted to an academic hospital's ICU between July 2014 and February 2015. The researchers also conducted an internet survey of 1,050 people with recent ICU experience. The study was published in the journal BMJ Quality and Safety.

Removal Of Tonsil Could Impact On Patient Immune System

Each year, over 530,000 children receive tonsillectomies to treat recurring middle-ear infections and obstructive sleep apnea (OSA) that are unresponsive to other remedies, but a recent study published shows the surgery could have long-term effects on respiratory and immune function.

Tonsillectomies

The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) stated that 30 years ago, 90% of tonsillectomies (which can also include adenoid removal) were done because of recurrent infection. Now, 20% of surgeries are performed to treat chronic infection, while 80% are done to treat OSA. The study was published online in JAMA Otolaryngology.

A Little Effect Of Hormone Therapy On Artery Thickness

A new study connects these two facts to demonstrate the little effect of hormone therapy on artery thickness as a precursor to heart disease. Heart disease is still the number one killer of US women, and hormone therapy remains a top treatment for menopause symptoms. The study was published online in Menopause, the journal of The North American Menopause Society (NAMS).

Symtoms Of Eczema Leads To Impaired Quality Of Life

If never suffered from eczema, also known as Atopic Dermatitis, you probably are not aware of the negative impact it can have on the quality of life. The severe itching, redness and excessively dry skin all make life miserable for those who suffer from the allergic disease. A new study published in the Annals of Allergy, Asthma and Immunology, the scientific journal of the American College of Allergy, Asthma, and Immunology (ACAAI) surveyed 602 adults with eczema
