Institutions' adherence to protocol, quality assurance, and radiation parameter reporting are key to adequately interpret and compare treatment outcomes in radiation oncology. In 2017, the editorial board for Veterinary Radiology & Ultrasound adapted author guidelines on "technical information for radiation therapy (RT)". These guidelines provide a framework to report the RT treatment process in manuscripts resulting from veterinary clinical trials. In spite of this framework, however, in implementing IMRT, we have identified different "interpretations" of the extended prescription and reporting recommendations of the International Commission on Radiation Units and Measurements (ICRU 83), even within our small team...

In the case of alternative psychosis and forced normalization, the patient alternates between periods of clinically manifest seizures and normal behavior, and other periods of seizure freedom (or significant seizure reduction) accompanied by psychosis or behavioral disturbances. Unlike the clinically defined alternative psychosis, forced normalization is based on EEG findings. In clinical practice and in the literature, both terms are mostly used synonymously, and they also describe the same clinical pictures...

Image artifacts due to 14 gauge radiotherapy electromagnetic (EM) transponders were assessed on conventional spin echo images, and corrected using metal artifact reduction techniques: high bandwidth, view angle tilting (VAT), and slice encoding for metal artifact correction (SEMAC). Large areas of signal loss and/or pile-up were produced in an area extending up to 15.3 mm in radius for 14G transponders in standard imaging. Using high bandwidth imaging with VAT, in-plane artifact sizes were reduced by up to 35%...

For the prevention and management of chronic diseases, global physical activity guidelines state that an adult should engage in regular moderate-to-vigorous aerobic physical activity (MVPA; e.g. walking, cycling, running) and muscle-strengthening exercise (MSE; e.g. strength/resistance training). However, the associations between combined MVPA-MSE with chronic health conditions are rarely examined in large population studies. In particular, little is known associations between combined MVPA-MSE with depressive disorders, one of the leading causes of disability worldwide...

Developmental neurotoxicity (DNT) is an important endpoint for the safety assessment of chemicals. However, the current in vivo animal model for DNT assessment is resource-intensive and may not fully capture all mechanisms that may be relevant to DNT in humans. As a result, there is a growing need for more reliable, time- and cost-efficient approaches for DNT evaluation. Towards this end, many stem/progenitor cell-based in vitro models and alternative organism-based models are becoming available with the potential for high throughput screening of DNT...

Plants reprogram somatic cells following injury and regenerate new tissues and organs. Upon perception of inductive cues, somatic cells often dedifferentiate, proliferate, and acquire new fates to repair damaged tissues or develop new organs from wound sites. Wound stress activates transcriptional cascades to promote cell fate reprogramming and initiate new developmental programs. Wounding also modulates endogenous hormonal responses by triggering their biosynthesis and/or directional transport. Auxin and cytokinin play pivotal roles in determining cell fates in regenerating tissues and organs...

Single-particle electron cryomicroscopy (cryo-EM) has led to a revolution in structural work on mammalian respiratory complex I. Complex I (mitochondrial NADH:ubiquinone oxidoreductase), a membrane-bound redox-driven proton pump, is one of the largest and most complicated enzymes in the mammalian cell. Rapid progress, following the first 5-Å resolution data on bovine complex I in 2014, has led to a model for mouse complex I at 3.3-Å resolution that contains 96% of the 8,518 residues and to the identification of different particle classes, some of which are assigned to biochemically defined states...

Paleontologists use fossil teeth to reconstruct the diets of early hominins and other extinct species. Some evidence is adaptive: nature selects for tooth size, shape, and structure best suited to specific food types. Other evidence includes traces left by actual foods eaten, such as microscopic tooth wear. This critical review considers how molars work, how they are used, and how occlusal topography and dental microwear can be used to infer diet and food preferences in the past, particularly for hominins of the Pliocene and early Pleistocene...

Extracellular diffusion in the brain is customarily characterized by two parameters, the extracellular space (ECS) volume fraction α and the diffusion tortuosity λ. How these two parameters are temporarily modified and correlated in a physiological/pathological event remains unclear to date. Using tetramethyl ammonium (TMA+ ) as the ECS ion tracer in a newly updated iontophoretic sinusoidal method, we studied in this work the dynamic α( t) and λ( t) in rat somatosensory cortex during spreading depression (SD)...

Lasers with pulse lengths from nanoseconds to femtoseconds and wavelengths from the mid-infrared to extreme ultraviolet (UV) have been used for desorption or ablation in mass spectrometry. Such laser sampling can often benefit from the addition of a second laser for postionization of neutrals. The advantages offered by laser postionization include the ability to forego matrix application, high lateral resolution, decoupling of ionization from desorption, improved analysis of electrically insulating samples, and potential for high sensitivity and depth profiling while minimizing differential detection...

A Lewis acid-promoted highly regio- and diastereoselective C(sp3 )-C(sp2 ) cross-coupling reaction between unprotected aryl-substituted 1,2-diols and styryl-, aryl-, heteroaryl-, and polyarylboronic acids has been developed in a one-pot procedure. The regioselective opening of aryl-substituted cyclic boronic esters promoted by a Lewis acid, followed by subsequent intramolecular 1,4-transfer of the carbon ligand from boron to a resonance-stabilized benzylic carbenium ion minimizing the allylic 1,3-strain in a stereoselective fashion led to the corresponding α-substituted syn-phenylethyl alcohols...

BACKGROUND: The increasing multidrug resistance among gram-negative uropathogens necessitates new treatments for serious infections. Plazomicin is an aminoglycoside with bactericidal activity against multidrug-resistant (including carbapenem-resistant) Enterobacteriaceae. METHODS: We randomly assigned 609 patients with complicated urinary tract infections (UTIs), including acute pyelonephritis, in a 1:1 ratio to receive intravenous plazomicin (15 mg per kilogram of body weight once daily) or meropenem (1 g every 8 hours), with optional oral step-down therapy after at least 4 days of intravenous therapy, for a total of 7 to 10 days of therapy...

Schizophrenia is a chronic disorder that can be effectively controlled but will likely require lifelong treatment. Unfortunately, most patients experience numerous relapses, ongoing symptoms, and impairment, often because of treatment interruptions. Continuous treatment is imperative to prevent relapse and the potentially devastating consequences that can follow a return of psychotic symptoms. Clinicians must better monitor a common cause of relapse, nonadherence, and offer strategies to improve adherence. Strategies can target the patient, the environment, or treatment...
