Electrochemical Removal of Se(IV) from Wastewater Using RuO-Based Catalysts.

The removal of selenite (SeO) from water is challenging due to the risk of secondary pollutants. To address this, we developed RuO-based nanocatalysts on the titanium plate (RuO/TP) for direct electrochemical reduction of Se(IV) to elemental selenium [Se(0)]. Optimizing Sn doping in RuO nanoparticles to induce charge redistribution enabled the RuSnO/TP catalyst to achieve ∼90% Se(IV) removal across concentrations of 0.

Stress Cardiac Magnetic Resonance Imaging in Intermediate-Risk Emergency Department Patients with Abnormal High-Sensitivity Troponin.

Microscopic Origin of the Spatial and Temporal Precision in Biological Systems.

All living systems display remarkable spatial and temporal precision, despite operating in intrinsically fluctuating environments. It is even more surprising given that biological phenomena are regulated by multiple chemical reactions that are also random. While the underlying molecular mechanisms of surprisingly high precision in biology remain not well understood, a novel theoretical picture that relies on the coupling of relevant stochastic processes has been recently proposed and applied to explain different phenomena.

Associations of Child Amygdala Development with Borderline Personality Symptoms in Adolescence.

Background: The understanding of the neural correlates of borderline personality disorder (BPD) is limited, but suggests alterations in limbic structures play a role in adult BPD. The developmental course of structural neural differences in BPD is unknown. Whether there is specificity for structural alterations in BPD compared with other psychiatric presentations, such as major depressive disorder (MDD), remains unexplored.

The early years were characterized by foundational developments, such as the installation of the first teletherapy units, low-dose-rate brachytherapy units, and conventional simulators, and the recognition of radiation oncologists and medical physicist professionals laid the groundwork for radiotherapy treatment modalities.

Current Evidence on the Care of Young Infants With Hypothermia in the Emergency Department.

The presence of hypothermia among young infants in the emergency department may be a sign of serious or invasive bacterial infections, or invasive herpes simplex viral infection. However, hypothermia may also occur due to a variety of other infectious and noninfectious conditions or environmental exposure. In some settings, hypothermia may represent a protective, energy-conserving response to illness.

Bone Marrow Niche in Cardiometabolic Disease: Mechanisms and Therapeutic Potential.

Cardiovascular and cardiometabolic diseases are leading causes of morbidity and mortality worldwide, driven in part by chronic inflammation. Emerging research suggests that the bone marrow microenvironment, or marrow niche, plays a critical role in both immune system regulation and disease progression. The bone marrow niche is essential for maintaining hematopoietic stem cells (HSCs) and orchestrating hematopoiesis.

Control of virulence and physiology by the flagellin homeostasis checkpoint FliC-FliW-CsrA in the absence of motility.

Unlabelled: Mutations affecting flagellin (FliC) have been shown to be hypervirulent in animal models and display increased toxin production and alterations in central metabolism. The regulation of flagellin levels in bacteria is governed by a tripartite regulatory network involving , , and , which creates a feedback system to regulate flagella production. Through genomic analysis of clade 5 strains (non-motile), we identified they have jettisoned many of the genes required for flagellum biosynthesis yet retain the major flagellin gene and regulatory gene .

A hierarchical pathway for assembly of the distal appendages that organize primary cilia.

Distal appendages are nine-fold symmetric blade-like structures attached to the distal end of the mother centriole. These structures are critical for formation of the primary cilium, by regulating at least four critical steps: ciliary vesicle recruitment, recruitment and initiation of intraflagellar transport (IFT), and removal of CP110. While specific proteins that localize to the distal appendages have been identified, how exactly each protein functions to achieve the multiple roles of the distal appendages is poorly understood.
