Narcissism linked to aggression in review of 437 studies

Eurekalert - May 25 2021 - 00:05
A comprehensive analysis of 437 studies from around the world provides the best evidence to date that narcissism is an important risk factor for both aggression and violence, researchers said.The link between narcissism and aggression was found for all dimensions of narcissism and for a variety of types of aggression. Results were similar regardless of gender, age, whether they were college students, or country of residence.

New research supports pridopidine's neuroprotective properties in Huntington's Disease models

Eurekalert - May 25 2021 - 00:05
Newly published papers further elucidate the mechanisms underlying pridopidine's neuroprotective properties through activation of the Sigma-1 Receptor (S1R). Pridopidine enhances mitochondrial function and reduces mHTT-induced ER stress, which are impaired in HD, mediated by the S1R. Three new peer-reviewed publications highlight pridopidine's therapeutic potential and provide data supporting the role of the S1R in neurodegenerative diseases

According to a new study, testosterone therapy may reduce non-alcoholic fatty liver disease in obese

Eurekalert - May 25 2021 - 00:05
Testosterone therapy may help obese men with functional hypogonadism and type-2 diabetes reduce the prevalence of non-alcoholic fatty liver disease (NAFLD), according to a study being presented at the 23rd?European Congress of Endocrinology (e-ECE 2021), on Tuesday 25 May 2021 at 14:00 CET (www.ece2021.org). The two-year study found that therapy with testosterone undecanoate normalised testosterone levels, reduced NAFLD, and suppressed the symptoms of hypogonadism in men living with these conditions.

Soft X-ray method promises nanocarrier breakthroughs for smart medicine

Eurekalert - May 25 2021 - 00:05
A new technique using chemically-sensitive "soft" X-rays offers a simpler, non-disruptive way of gaining insight into nanocarriers. Currently researchers have to rely on attaching fluorescent dyes or heavy metals to label parts of organic nanocarrier structures for investigation, often changing them in the process. Researchers have demonstrated the capability of the new X-ray method on a smart drug delivery nanoparticle and a polysoap nanostructure intended to capture crude oil spilled in the ocean.

Press (re)play to remember - How the brain strengthens memories during sleep

Eurekalert - May 25 2021 - 00:05
While we sleep, the brain produces particular activation patterns. When two of these patterns - slow oscillations and sleep spindles - gear into each other, previous experiences are reactivated. The stronger the reactivation, the clearer will be our recall of past events, a new study reveals.

Harnessing next generation sequencing to detect SARS-CoV-2

Eurekalert - May 25 2021 - 00:05
Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Mothers' depression impacts mother-infant relationships

Eurekalert - May 25 2021 - 00:05
Research led by King's College London has found that women with depression during pregnancy, or with a history of depression, had a reduced quality of mother-infant interaction at both eight weeks and 12 months after their babies were born.

Whale carcasses help answer mysteries of elusive species

Eurekalert - May 25 2021 - 00:05
A new study published by the open access publisher Frontiers shows the usefulness of opportunistically collected specimens, such as stranded carcasses, to study elusive species. The researchers used stable isotope analysis of skin, muscle, and bone tissue of Sowerby's beaked whales to study their spatial ecology. They found that the species exhibits both short- and long-term habitat fidelity. The results are published in Frontiers in Conservation Science and show the importance of such studies for marine wildlife conservation.

Ancient fish bones reveal non-kosher diet of ancient Judeans, say researchers

Eurekalert - May 25 2021 - 00:05
Ancient Judeans commonly ate non-kosher fish surrounding the time that such food was prohibited in the Bible, suggests a study published in the peer-reviewed journal Tel Aviv.This finding sheds new light on the origin of Old Testament dietary laws that are still observed by many Jews today. Among these rules is a ban on eating any species of fish which lacks scales or fins.

Antibodies that enhance SARS-CoV-2 infection -- A possible factor for severe COVID-19

Eurekalert - May 24 2021 - 00:05
Osaka University researchers found that infection with SARS-CoV-2 produces not only neutralizing antibodies that prevent infection, but also infection-enhancing antibodies. They demonstrated that the infection-enhancing antibodies enhance the infectivity of SARS-CoV-2 by modulating the conformation of spike protein of SARS-CoV-2. Furthermore, the infection-enhancing antibodies attenuated the ability of neutralizing antibodies to prevent infection. Their findings will help to develop vaccines that do not induce the production of infection-enhancing antibodies.
