Erythrocyte Phenotype in a Pregnant Woman of Sri Lanka

The Bombay phenotype is a rare genetic trait which is characterized by the absence of A, B and H antigens on red cells as well as in body secretions. The serum shows the presence of antibodies against antigen H. Patients with this rare blood type are not easily transfusable. We had observed a woman aged 18, at the 20th week of pregnancy, the native of Sri Lanka, with an IgG and IgM class anti-H. Researchers report the case and the clinical issues arose.

Bone Loss In A Space Environment, Including Microgravity, Ionizing Radiation

Bone loss mainly induced by microgravity has been determined as one of the most harmful outcomes observed in astronauts. The complex environment in space, including microgravity, radiation, circadian rhythm, and extreme temperature, may injure human health during long-term space travel. The continuous bone loss may elevate the risk of developing fractures in the skeletal framework of astronauts during or after space missions.

To Compare The Efficacy Of Drugs Used And Duration Of Postoperative Analgesia

Spinal anesthesia is a widely used technique providing faster onset with effective and uniformly distributed sensory and motor block. Due to decreased cardiovascular and central nervous system toxicity, levobupivacaine is a good alternative for spinal anesthesia. Dexmedetomidine, when used intrathecally, is associated with prolonged motor and sensory block, hemodynamic stability, and less requirement of rescue analgesia in 24 hours.

A Dietary Supplement Speeds Melanoma Cell Growth

According to a study, researcher determines that a dietary supplement taken to strengthen joints, i.e, Chondroitin sulfate. One particular mutation in the B-raf gene (V600E) can be found in about half of melanomas. Jing Chen, Ph.D. and colleagues found that chondroitin sulfate can boost growth by melanoma cells carrying the V600E mutation, but not other melanoma cells. The study was published in Molecular Cell.

Image-Guided Cancer Surgery Improved

By mimicking the intricate visual system of a butterfly, researchers have created a camera that provides surgeons with both a traditional color image as well as a near-infrared image that makes fluorescently labeled cancerous cells visible even under bright surgical lighting.

The new camera is designed to help surgeons remove all the cancerous cells without damaging healthy tissue, making it less likely that cancer will spread and reducing the need for multiple surgeries.
