New computational simulations suggest that the effects of antibiotics on a bacterial community depend on whether neighboring species have competitive or cooperative relationships, as well as their spatial arrangement.
A joint is defined as a point where 2 bones articulate or make contact. Joints can be classified in 2go ways:
(1) histologically, based on the type of connective tissue which is dominant in the joint
(2) functionally, based on the amount of movement permitted between the bones forming the joint. Based on the histological classification, the 3 types of joints in the human body are fibrous, cartilaginous, and synovial.
A novel, intelligent theranostic agent for precise tumor diagnosis and therapy, has been developed that remains as small molecules while circulating in the bloodstream. It was presented at 2018 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging
In the 1966 novel, Fantastic Voyage, written by biochemist and author Isaac Asimov, a crew of people become miniaturized in order to travel through the body of a scientist and save him from a blood clot in his brain.
The risk for infective endocarditis climbs significantly after many invasive therapeutic and diagnostic procedures and is especially high after some common ones, such as bronchoscopy and coronary angiography, conclude investigators of a large observational study that included cases from 1998 to 2011.
The analysis, which excluded dental procedures in Sweden, invites at least a partial reappraisal of guidelines from a decade ago that dramatically cut reliance on antibiotic prophylaxis with dental and many nondental invasive procedures. The study was published in the Journal of the American College of Cardiology.
Restricting use of neoadjuvant chemoradiation (CRT) to patients with "high-risk" rectal cancers is a sensible strategy with "good results," according to the authors of a prospective observational multicenter study from Germany.
The new influenza drug Xofluza, developed by the Japanese pharmaceutical company Shionogi, was approved for clinical use in Japan in February 2018. Scientists from EMBL Grenoble have now investigated the drug's mode of action in detail and uncovered possible mechanisms by which viral resistance to it could emerge. Scientific Reports published the results of the study.
The research examined that palliative care can sharply reduce medical costs, Doctors can improve the quality of life for their seriously ill patients while also reducing the patients' medical expenses if they make use of one particular care model.
The biggest hurdle might well be the words used to describe it, said Dr. Jeanine Ellinwood, who leads a team in the specialized field. People hear them, she said, and think immediately of hospice care.
Researchers have demonstrated the feasibility of implanting a micro pacemaker system in the pericardial sac surrounding the heart a breakthrough that may open up new cardiac pacing options for children and adults.
The micro pacemaker inserted through a single tiny incision avoids an invasive surgical procedure and the complications related to long pacemaker leads. The study, "Minimally Invasive Implantation of a Micro pacemaker into the Pericardial Space." The study was published in Circulation: Arrhythmia and Electrophysiology.
