Targeted mutagenesis of the vacuolar H translocating pyrophosphatase gene reduces grain chalkiness in rice.

Grain chalkiness is a major concern in rice production because it impacts milling yield and cooking quality, eventually reducing market value of the rice. A gene encoding vacuolar H translocating pyrophosphatase (V-PPase) is a major quantitative trait locus in indica rice, controlling grain chalkiness. Higher transcriptional activity of this gene is associated with increased chalk content.

TAVR vs balloon aortic valvotomy for severe aortic stenosis and cardiogenic shock: An insight from the National Inpatient Sample database.

Background: Severe Aortic stenosis (AS) complicated by cardiogenic shock (CS) represents a grave clinical condition with limited treatment options. Evidence from small observation studies favors that Transcatheter Aortic Valve Replacement (TAVR) might be a feasible option in these patients in contrast to emergent Balloon Aortic Valvuloplasty (BAV) which is associated with very high short and long-term mortality.

Methods: 11,405 hospitalizations with severe AS complicated by CS between 2016 and 2020 were identified using the National Inpatient Sample (NIS) Database, and patients were then stratified according to whether they received TAVR or BAV.

Radiation-Induced Intestinal Normal Tissue Toxicity: Implications for Altered Proteome Profile.

Radiation-induced toxicity to healthy/normal intestinal tissues, especially during radiotherapy, limits the radiation dose necessary to effectively eradicate tumors of the abdomen and pelvis. Although the pathogenesis of intestinal radiation toxicity is highly complex, understanding post-irradiation alterations in protein profiles can provide crucial insights that make radiotherapy safer and more efficient and allow for increasing the radiation dose during cancer treatment. Recent preclinical and clinical studies have advanced our current understanding of the molecular changes associated with radiation-induced intestinal damage by assessing changes in protein expression with mass spectrometry-based approaches and 2-dimensional difference gel electrophoresis.

Testosterone, cortisol, and criminal behavior in men and women.

Only two studies to date have considered the joint effects of testosterone and cortisol on direct measures of criminal behavior. The current study extends this earlier work by incorporating the direct and interactive effects of baseline hormone measures and hormone change scores in response to social stress. The current study also extends prior work by considering distinct measures of different criminal behavior types and sex differences.

Towards rainbow portable Cytophone with laser diodes for global disease diagnostics.

In vivo, Cytophone has demonstrated the capability for the early diagnosis of cancer, infection, and cardiovascular disorders through photoacoustic detection of circulating disease markers directly in the bloodstream with an unprecedented 1,000-fold improvement in sensitivity. Nevertheless, a Cytophone with higher specificity and portability is urgently needed. Here, we introduce a novel Cytophone platform that integrates a miniature multispectral laser diode array, time-color coding, and high-speed time-resolved signal processing.

Headache Diagnosis in Children and Adolescents.

Pediatric headache is a common medical complaint managed across multiple subspecialties with a myriad of unique factors (clinical presentation and disease phenotype) that make accurate diagnosis particularly elusive. A thorough understanding of the stepwise approach to headache disorders in children is essential to ensure appropriate evaluation, timely diagnosis, and efficacious treatment. This work aims to review key components of a comprehensive headache assessment as well as discuss primary and secondary headache disorders observed in children, with a particular focus on clinical pearls and "red flag" symptoms necessitating ancillary diagnostic testing.

Metabolism, CB1 cannabinoid receptor binding and in vivo activity of synthetic cannabinoid 5F-AKB48: Implications for toxicity.

AKB48 and its fluorinated derivative 5F-AKB48 are synthetic cannabinoids (SCs) which have caused hospitalizations and deaths in human users. Abuse of SCs is dangerous because users may mistake them for natural cannabis, which is generally considered to be unlikely to elicit adverse effects. The present studies were designed to investigate the in vitro oxidative metabolism of 5F-AKB48 by human microsomal fractions from different organs and sexes as well as recombinant human cytochrome P450s (P450s).

Pancreatic cancer is one of the most complex types of cancers to detect, diagnose, and treat. However, the field of nanomedicine has strong potential to address such challenges. When evaluating the diffusion and penetration of theranostic nanoparticles, the extracellular matrix (ECM) is of crucial importance because it acts as a barrier to the tumor microenvironment.

Optimizing Lignosulfonic Acid-Grafted Polyaniline as a Hole-Transport Layer for Inverted CHNHPbI Perovskite Solar Cells.

A conducting polymer of lignosulfonic acid-grafted, polyaniline-doped camphorsulfonic acid (LS-PANI-CSA), created via a low-temperature solution process, has been explored as an efficient hole-transport layer (HTL) for inverted single cation-anion CHNHPbI perovskite solar cells. The performance of the solar cell was optimized in this study by tuning the morphology and work function of LS-PANI-CSA films using dimethylsulfoxide (DMSO) as a solvent in treatment. Results showed that DMSO washing enhanced the electronic properties of the LS-PANI-CSA film and increased its hydrophobicity, which is very important for perovskite growth.
