Intratumoral peripheral small papillary tufts might be a diagnostic clue of BHD

by Lizzie Perdeaux in BHD Research Blog

Contrary to other hereditary kidney cancer conditions, BHD-associated renal tumours are known to be histologically diverse and discordant within families, meaning that members of the same family do not necessarily get the same type of kidney tumour (Pavlovich et al., … Continue reading →...

Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces

by Farid Pazhoohi in Epistemophil

Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men’s preference for femininity in women’s faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of […]... Read more »

WHAT MAKES A CANCER A CANCER? THE HALLMARKS OF CANCER.

by Robb Hollis in Antisense Science

Cancer – the ‘C word’ in far too many of our lives. Wherever you are, it’s unlikely you’ll be able to avoid the news reports and personal stories about people fighting against cancer. Understanding how the disease occurs and how it takes hold over the body is key for developing effective new treatments and managing patients in the clinic, and so huge amounts of money are invested in cancer research every year. But what actually is cancer and how does it develop?... Read more »

A New way to Fight HIV, Using your Genome!

by Gabriel in Lunatic Laboratories

Outsmarting something as “simple” as a virus doesn’t seem like much of a challenge. If only you could set it down to take the SAT’s or something. Unfortunately in the body fighting HIV is more like guerrilla warfare, you take the big losses for a small win. This is no way to wage a war, but HIV is smart. It mutates and sidesteps anything we’ve been able to throw at it. We don’t have a cure, or a vaccine, but we do have scientists trying. New research has made a crucial jump to throwi........

Stress Impedes Wound Healing In Living Kidney Donors

by Cristy at Living Donor 101 in Living Donors Are People Too

52 living kidney donors underwent the hand-assisted laparoscopic procedure then had ultrasounds to measure wound healing.   Higher pre-operative life stress, lower optimism and lower conscientiousness were associated with delayed wound healing in living kidney donors for both outcomes. Increased emotional stability was associated with faster wound healing as demonstrated by a change in median …

Profiling Risk: Predicting Alcoholism In Adolescents

by Agnese Mariotti in United Academics

It appears that certain personality traits and traumatic early life events are typically associated with binge drinking in teenage years. However, the predictive power of each type of factors by itself (personality or individual history for example) is not absolute. A new study evaluated not only one single factor, but a series of psychological, genetic, and neurological elements for their ability to determine, when combined, current and future alcohol misuse in a large group of youngsters. ...

How your mood changes your personality

by Christian Jarrett in BPS Research Digest

Participants scored higher on neuroticism & lower on extraversion when they were sadExcept in extreme cases of illness or trauma, we usually expect each other's personalities to remain stable through life. Indeed, central to the definition of personality is that it describes pervasive tendencies in a person's behaviour and ways of relating to the world. However, a new study highlights the reality - your personality is swayed by your current mood, especially when you're feeling down.Jan Quere........ Read more »

Blood lead levels and childhood behaviour

by Paul Whiteley in Questioning Answers

"Blood lead concentrations, even at a mean concentration of 6.4 µg/dL, were associated with increased risk of behavioral problems in Chinese preschool children, including internalizing and pervasive developmental problems". That was the conclusion of the study by Jianghong Liu and colleagues [1] looking at blood lead levels in preschoolers aged 3-5 years resident in Jiangsu province in China. Some associated media accompanying this study can be viewed here including the text: "This re........ Read more »

Know your brain: Thalamus

by neurosci in Neuroscientifically Challenged

Where is it?











Thalamus (in red).






The thalamus is a large, symmetrical (meaning there is one in each hemisphere) structure that makes up most of the mass of the diencephalon. A large number of pathways travel through the thalamus, including all of the sensory pathways other than those devoted to olfaction (smell).What is it and what does it do?The thalamus is often described as a relay station. This is because almost all sensory informati........ Read more »

Coronavirus nsp, ER stress, UPR, and ERAD

by thelonevirologist in Virology Tidbits

The essential step in the intracellular life cycle of many positive strand ssRNA viruses is the generation of double membrane vesicles (DMVs) that in most cases (but not all) contain the viral replication and transcription complexes (RTC) and hence serve as the replication platform. In the case of both the Nidovirales and the Flaviviridae these are formed by subverting the membrane of the ER in the absence of conventional ER and secretory pathway markers. Additionally, non-structural proteins (........ Read more »

What does it feel like to be depressed?

by Christian Jarrett in BPS Research Digest

We're used to reading about depression as a checklist of symptoms. These lists have their uses, but arguably they miss the human story of what depression truly feels like. Now the psychologists Jonathan Smith and John Rhodes have published their analysis of the first-hand accounts of seven therapy clients, (three women and four men) about what it's like to be depressed for the first time. The participants had an average age of 44, and all had been referred for therapy in London.The first theme t........ Read more »

Video Tip of the Week: VectorBase, for invertebrate vectors of human pathogens
