ORIENT-12 Study demonstrates adding sintilimab to gemcitabine/platinum has clinical benefit
Adding sintilimab to a regimen of gemcitabine and platinum demonstrates clinical benefit over gemcitabine and platinum alone as first-line therapy in patients with locally advanced or metastatic squamous cell non-small cell lung cancer, according to a study published in the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer.

Low blood flow in the brain may be an early sign of Parkinson's disease
Patients who suffer from REM sleep behaviour disorder have altered blood flow in the brain, which can lead to a lack of oxygen in the brain tissue. In the long term, this may cause symptoms of Parkinson's disease. This is shown by research from Aarhus University and Aarhus University Hospital.

'Slow slip' earthquakes' hidden mechanics revealed
Scientists at The University of Texas at Austin have used seismic 'CT' scans and supercomputers to reveal the inner workings of a region off the coast of New Zealand known to produce slow motion tremors, also called slow slip earthquakes. The insights help scientists pinpoint why tectonic energy at subduction zones is sometimes released gently as slow slip, and other times as devastating, high-magnitude earthquakes.

Immune function of small chloroplasts in the epidermal cells of plants
It is said that 10 to 15% of the world's agricultural production loss is caused by diseases, which is equivalent of the food for about 500 million people. And since 70-80% of this plant disease is caused by filamentous fungi, protecting crops from filamentous fungi is an important issue in effectively feeding the world population. The researchers found that small chloroplasts in the epidermis of plants control the entry of fungal pathogens.

Egyptian fossil surprise: Fishes thrived in tropics in ancient warm period, despite high ocean tempe
The Paleocene-Eocene Thermal Maximum, or PETM, was a short interval of highly elevated global temperatures 56 million years ago that is frequently described as the best ancient analog for present-day climate warming.

National survey of frontline health care workers finds fear, unsafe working conditions
A new report summarizes the findings from a national survey of frontline health care workers during the early days of the COVID-19 pandemic, finding that many reported unsafe working conditions and retaliation for voicing their concerns to employers.

Narcissism linked to aggression in review of 437 studies
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
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
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
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.

Engineering matter at the atomic level
In a breakthrough that will contribute to this, published in Nature Communications, researchers from the RIKEN Cluster for Pioneering Research and RIKEN Center for Advanced Photonics, along with collaborators, have developed a way to use a "dry transfer technique"--a technique that uses no solvent--to position optical quality carbon nanotubes in a precise way.

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