Activation of an S6/H4 Kinase (PAK 65) from Human Placenta by Intramolecular and Intermolecular Autophosphorylation

Description: Article proposing a model in which phosphorylation of sites 1 and 2 occurs sequentially. The model proposes that trypsin treatment of the inactive holoenzyme removes an inhibitory rac-binding domain which blocks MgATP access to the catalytic site. The pseudosubstrate domain at site 1 is autophosphorylated and subsequent bimolecular autophosphorylation at site 2 fully opens the catalytic site.

N-acylethanolamide metabolizing enzymes are upregulated in human neural progenitor-derived neurons exposed to sub-lethal oxidative stress

Description: Article is a study determining whether ReN cells, a superior cell model system for studying neurodevelopment, differentiation, and neuroprotection, express proteins involved in canonical eCB NAE signaling and whether oxidative stress can induce their expression. This study is a first step toward determining how oxidative stress affects CB1, CB2, FAAH, NAAA, and NAPE-PLD expression and their potential defense against oxidative stress.

AFLOW-QHA3P: Robust and automated method to compute thermodynamic properties of solids

Description: Article introducing the quasiharmonic approximation three-phonon method to calculate the thermodynamic properties of both nonmetallic and metallic compounds. This study demonstrates that QHA3P is an ideal framework for the high-throughput prediction of finite-temperature material properties, combining the accuracy of QHA with the computational efficiency of SC-QHA.

Case report: Early-onset osteoporosis in a patient carrying a novel heterozygous variant of the WNT1 gene

Description: Article presents a case study of a 35 year-old Caucasian woman who experienced multiple vertebral fractures two months after her second pregnancy. The results suggest a potential role of heterozygous WNT1 variants in the pathogenesis of early-onset osteoporosis. The authors suggest that teriparatide is one of the most appropriate available therapies for such cases.

Embryonic developmental oxygen preconditions cardiovascular functional response to acute hypoxic exposure and maximal β-adrenergic stimulation of anesthetized juvenile American alligators (Alligator mississippiensis)

Description: Article investigating the effect of embryonic hypoxia on the cardiovascular phenotype of 4-year-old American alligators (Alligator mississippiensis). The findings indicate that embryonic hypoxia in crocodilians alters the cardiovascular phenotype, changing the juvenile response to acute hypoxia and β-adrenergic stimulation.

Exposure to diesel exhaust particulates and desert sand dust generates microvesicle particles and platelet-activating factor agonists

Description: The authors address the editor in their article, stating that the majority of the general population, particularly, servicemen and women deployed across the globe are exposed to various airborne hazards, including diesel exhaust particulate (DEP) and desert sand dust (DSD). Studies, including the author's study, have shown that exposure to ROS-generating pro-oxidative stressors ranging from environmental carcinogens to pollutants, including cigarette smoke, produces a class of potent phospholip… more

Giant spin Hall effect in two-dimensional monochalcogenides

Description: This article, using calculations from first principles, reveals for the first time giant intrinsic spin Hall conductivities (SHC) in these materials. In particular, the article shows that the SHC resonances can be easily tuned by combination of strain and doping and, in some cases, strain can be used to induce semiconductor to metal transition that makes a giant spin Hall effect possible even in absence of doping.

Influence of coherent population trapping on Raman scattering

Description: Article considering the Raman scattering in molecular media. Applying two laser fields in a two-photon resonance with vibrational transition, the authors study the role of rotational levels for excitation of vibrational coherence. It is shown that the molecular vibrational coherence strongly depends on the effect of coherent population trapping for rotational levels. The obtained results are important for applications of Raman spectroscopy to molecular detection in engineering, chemical, and bi… more

POSMM: an efficient alignment-free metagenomic profiler that complements alignment-based profiling

Description: Article presents POSMM, Python-Optimized Standard Markov Model classifier, which is a new incarnation of the Markov model approach to metagenomic sequence analysis. The authors claim that by combining POSMM with ultrafast classifiers such as Kraken2, their complementary strengths can be leveraged to produce higher overall accuracy in metagenomic sequence classification than by either as a standalone classifier. POSMM is a user-friendly and highly adaptable tool designed for broad use by the met… more
