Taking Two Antibiotics for Quick Recovery?
by Geetanjali Yadav in United Academics
Did you ever take two or more antibiotics in order to get rid of a disease? New research in PLOS Biology suggests that this is not a wise thing to do. Drug resistant bacteria grow faster than their weaker counter parts when resources are limiting and many antibiotics are consumed.... Read more »

New Insight into Meat vs Fish Debate
by Mark Fonseca Rendeiro in United Academics
The benefits of taking fish oil and the harm caused by eating red meat, these two nutritional nuggets of wisdom have been passed around so much over the past few decades, we rarely stop to ask if they really do what people claim they do.
This month, two new papers on the subject of fish and meat have come forward from the University of Western Australia. The first examines the real impact of taking fish oil supplements on the diets of obese people.... Read more »

Will IV Oxygen Save Lives?
by Rogue Medic in Rogue Medic
Intravenous oxygen delivery that works?
Maybe temporary oxygenation, but not yet.
Will this change the approach to CICV (Can’t Intubate, Can’t Ventilate) patients?
No, but it may change the approach to CICO (Can’t Intubate, Can’t Oxygenate) patients.
The distinction is important. ... Read more »

UF researchers develop ‘nanotrain’ for targeted cancer drug transport
by Perikis Livas in Tracing Knowledge
University of Florida researchers have developed a “DNA nanotrain” that fast-tracks its payload of cancer-fighting drugs and bioimaging agents to tumor cells deep within the body. The nanotrain’s ability to cost-effectively deliver high doses of drugs to precisely targeted cancers and other medical maladies without leaving behind toxic nano-clutter has been the elusive Holy Grail for scientists studying the teeny-tiny world of DNA nanotechnology....

Pericytes can be used for muscle regeneration
by beredim in Stem Cells Freak
Researchers from the Wake Forest Baptist Medical Center (WFBMC) announced today that they may have unveiled some of the mechanisms involved in obesity, diabetes mellitus type 2, muscular dystrophy and other diseases associated with fat replacing muscle tissue, causing it to weaken and degenerate. Their findings have the potential to lead to new therapies for the aforementioned diseases, say the researchers.Read More... Read more »

Video Tip of the Week: My Cancer Genome
There are a lot of cancer database resources out there. Most of the ones we’ve focused on have been the data repository types.

Molecular Evidence for Memory Consolidation during REM Sleep
by Allison in Dormivigilia
Molecular biologists have observed changes in common signaling cascades throughout the course of REM sleep episodes (in rodents) with disruption to these signaling cascades leading to memory deficits. It's good to see a paper focusing on mechanism now that we have a plethora of papers showing that depriving yourself of REM sleep can have detrimental effects on all types of memory (episodic, emotional, declarative, procedural) ...

Lyme and soda: hold the autism risk?
by Paul Whiteley in Questioning Answers
I've talked about the mighty tick previously on this blog and some speculation on how a tick harbouring the bacteria Borrelia burgdorferi (or a close relation) bites and transmits said bacteria to humans which can lead to Lyme disease and whether this might be implicated in some cases of autism. Tickety boo @ Wikipedia The suggestion from that post was that whilst the data was speculative and relatively sparse at that time on whether Lyme disease is common in cases of autism........

The Climatic Origins of the Malaysian Nipah Virus Outbreak
by Rebecca Kreston in BODY HORRORS
One of the hardest questions to answer in an infectious disease outbreak investigation is "Why?"
Why then? Why there? These questions can be almost impossible to answer - not only because of their heady metaphysical nature but also because of the difficulty of assessing the minute interactions between microbe, environment and human host. Public health officials are often left shrugging their shoulders, half-heartedly admitting to an unsatisfied public that they just don't know ........ Read more »

The number people suffereing from Parkison's disease in the United States is estimated to be between 500,000 and 1,000,000.The key symptoms of Parkinson's disease include tremor and slowed movement or bradykinesia.Known risk factors for Parkinson's disease include advanced age, male gender, family history of Parkinson's disease and exposure to pesticides.Of note, smokers appear to have a reduced risk of Parkinson's disease although the mechanism for this protective effect is unknown.Romero and c........

Autism and the folding placenta
by Paul Whiteley in Questioning Answers
Men don't generally talk about placentas it has to be said. But today, in the name of blogging, I'm going to.I'm going to start by telling you how the placenta really is a marvel of biological engineering. An absolutely vital part of our existence in-utero that nourishes us and protects us during our earliest days living in the amniotic sac. Little wonder that whole nations have come to revere the placenta as mother, sibling even doubles of ourselves (see here). Although I have to say I do ........ Read more »
