Thinking about high-dose vitamin D supplements for your athletes? Make sure the dose is right.

by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field

A Blanket high dose vitamin D supplement plan results in elevated levels of vitamin D metabolites after the supplementation is completed. This could result in lower than normal levels of vitamin D, which is the opposite effect of the intended supplementation.... Read more »

Finding the Best Personalized Cancer Therapy

by Agnese Mariotti in United Academics

It would be great if, before starting a therapy, it was possible to test small doses of several drugs, at the same time, in a patient and compare their effects on the tumor, so to identify the one that works best.
The study of Yaari and colleagues from the Israel Institute of Technology in Haifa, published in Nature Communication, opens a way to this achievement.... Read more »

Are American Professors More Responsive to Requests Made by White Male Students?

by Jalees Rehman in The Next Regeneration

The vast majority of professors will gladly meet a prospective graduate student and discuss research opportunities as well as long-term career options, especially if the student requesting the meeting clarifies the goal of the meeting. However, there are cases when students wait in vain for a response. Is it because their email never reached the professor because it got lost in the internet ether or a spam folder? Was the professor simply too busy to respond? A research study headed by Katherine........ Read more »

Source regions of the type II radio burst observed during a CME–CME interaction on 2013 May 22 by P. Mäkelä et al.*

by CESRA in Solar Radio Science

Occasionally the Sun ejects a pair of magnetized plasma clouds, called coronal mass ejections (CMEs), roughly into the same propagation direction in closely timed sequence. If the second CME is faster than the first one, the CMEs could either just slip through each other or they could collide and interact, [...]... Read more »

Infections treated with anti-infective agents linked to schizophrenia?

by Paul Whiteley in Questioning Answers

Identify everyone born in Denmark between 1985-2002. Identify those treated "in the primary care setting" for an infection. Identify those diagnosed with schizophrenia and affective disorders. Look-see whether there is an overlap between infection or treated infection and schizophrenia / affective disorders. Report results.That's basically the study published by Köhler and colleagues [1] (a name that has appeared on this blog before) who concluded that: "Infections treated with anti-infect........

Double-blind randomised, placebo-controlled trial of vitamin D in autism

by Paul Whiteley in Questioning Answers

It was inevitable ("it is your destiny") that I would formulate a post about the paper published by Khaled Saad and colleagues [1] reporting results based on "a double-blinded, randomized clinical trial (RCT)" looking at the potential usefulness of a vitamin D supplement on "the core symptoms of autism in children." Inevitable because the peer-reviewed research literature looking at the sunshine vitamin/hormone in relation to autism is getting rather voluminous (see here and see here f........ Read more »

Do Synapses Really Store Memories?

by Neuroskeptic in Neuroskeptic_Discover

Most neuroscientists will tell you that long-term memories are stored in the brain in the form of synapses, the connections between neurons. On this view, memory formation occurs when synaptic connections are strengthened, or entirely new synapses are formed.



However, in a new piece in Frontiers in Systems Neuroscience, Austrian researcher Patrick C. Trettenbrein critiques the synapse-memory theory: The Demise of the Synapse As the Locus of Memory.



Trettenbrein acknowledges that "t... Read more »

Parent-mediated interventions for young children with autism meta-analysed

by Paul Whiteley in Questioning Answers

Do not mess with  Lois.Today I'm posting on the topic of the paper by Rose Nevill and colleagues [1] concluding: "that while most outcome domains of parent-delivered intervention are associated with small effects, the quality of research is improving."Parent-mediated interventions in relation to autism have been covered on this blog quite recently (see here) accompanied by that 'super-parenting' headline fail. Such approaches work on the idea that helping parents to "develop strategies........ Read more »

Parkour Athletes Teach Scientists about Swinging Apes

by Elizabeth Preston in Inkfish



"I was at a conference, and a colleague was talking about the locomotion of great apes in the trees," says Lewis Halsey, a physiologist at the University of Roehampton in London. The colleague mentioned that it's tough to measure how these animals use energy. That's when Halsey had an epiphany. "I was working with parkour athletes on another project," he says, studying how much energy the athletes used while jumping and climbing around a city. Why not use these human athletes to stand in........ Read more »

Case studies: BHD syndrome associated with pulmonary malformation and with lung neoplasm

by Joana Guedes in BHD Research Blog

Matsutani et al. (2016) reported for the first time BHD syndrome accompanied by pulmonary arteriovenous malformation. The patient, a young male with no significant medical history, presented with chest pain. Chest X-ray and CT revealed emphysematous changes in both lungs and a tumour with pleural fluid. A thoracoscopy revealed dark red pleural fluid and multiple cysts in the lung. The tumour lesion was resected and identified as a non-malignant intrapulmonary hematoma caused by a significant hae........ Read more »

The prebiotic galactooligosaccharide (B-GOS) and autism: just add to poo(p)

by Paul Whiteley in Questioning Answers

Yes, it is childish but...With all the continued chatter on a possible role for the collected gut microbiota - those wee beasties that inhabit our deepest, darkest recesses - in relation to some autism (see here for example), the paper by Roberta Grimaldi and colleagues [1] (open-access available here) provides yet more potentially important information.So, poo(p) samples were the starring material in the paper - "obtained from three non-autistic children and three autistic child donors"- and sp........

Dietary fibre deficiency and gut barrier integrity

"Dietary fiber deprivation, together with a fiber-deprived, mucus-eroding microbiota, promotes greater epithelial access and lethal colitis by the mucosal pathogen, Citrobacter rodentium."So said the findings reported by Mahesh Desai and colleagues [1] meriting an editorial in the publishing journal [2] as the sentiments of 'eating your greens' applies to some rather interesting [mouse] findings.Fibre (UK spelling) comes in various different forms typically categorised as soluble and insoluble d........
