BACKGROUND: Anthracyclines are cardiotoxic; however, there are limited data characterizing the serial changes in cardiac structure and function after anthracyclines. The aim of this study was to use cardiac magnetic resonance to characterize anthracycline-induced cardiotoxicity in mice. METHODS AND RESULTS: This was a longitudinal cardiac magnetic resonance and histological study of 45 wild-type male mice randomized to doxorubicin (n=30, 5 mg/kg of doxorubicin/week for 5 weeks) or placebo (n=15)...

The authors discuss the main climate change impacts on pastoralist societies, including those on rangelands, livestock and other natural resources, and their extended repercussions on food security, incomes and vulnerability. The impacts of climate change on the rangelands of the globe and on the vulnerability of the people who inhabit them will be severe and diverse, and will require multiple, simultaneous responses. In higher latitudes, the removal of temperature constraints might increase pasture production and livestock productivity, but in tropical arid lands, the impacts are highly location specific, but mostly negative...

Medication nonadherence is associated with adverse outcomes. To evaluate antihypertensive medication adherence and its association with blood pressure (BP) control, the authors described population adherence to prescribed antihypertensive medication (proportion of days covered ≥80%) and BP control (mean BP <140/90 mm Hg) among central Alabama veterans during the fiscal year 2015. Overall, 75.1% of patients receiving antihypertensive medication were considered adherent, and 66.1% had adequate BP control...

FIAT (Factor Inhibiting ATF4-mediated Transcription) interacts with ATF4 to repress its transcriptional activity. We performed a phenotypic analysis of Fiat-deficient male mice (Fiat(-/Y)) at 8 and 16 weeks of age. Fiat(-/Y) mice appeared normal at birth and weight gain was comparable between genotypes. μCT analysis of proximal femur demonstrated 46% and 13% age-dependent increases in trabecular bone volume and thickness, respectively, in Fiat(-/Y) mice. Cortical bone measurements at the femoral midshaft revealed a significant increase in cortical thickness in older Fiat(-/Y) mice...

The thioredoxin system plays a central role in the intracellular redox maintenance in the majority of cells. The canonical system is comprised of an NADPH-dependent thioredoxin reductase (TrxR) that reduces the disulfide reductase thioredoxin (Trx). Although Trx is encoded in almost all sequenced genomes of methanogens, its incorporation into their unique physiology is not well understood. Methanosarcina acetivorans contains a single TrxR (MaTrxR) and seven Trx (MaTrx1-7) homologs. We previously showed that MaTrxR and at least MaTrx7 comprise a functional NADPH-dependent thioredoxin system...

A 55-year-old Indian man presented with productive cough and a large left pleural effusion. Pleural fluid culture grew Mycobacterium tuberculosis, and he was started on antituberculosis therapy. One week later, the patient presented to hospital with drowsiness, dehydration and hypotension. He was transferred to critical care and only improved after starting hydrocortisone and stopping rifampicin. His short synACTHen test subsequently confirmed primary adrenal insufficiency, and a CT of the abdomen showed bilateral adrenal enlargement...

Melanocortin 4 receptor (MC4R) variants contribute to human obesity, and rats lacking functional MC4R (Mc4r(K314X/K314X)) are obese. We investigated the hypothesis that low energy expenditure (EE) and physical activity contribute to this obese phenotype in male rats, and determined whether lack of functional MC4R conferred protection from weight loss during 50% calorie restriction. Though Mc4r(K314X/K314X) rats showed low brown adipose Ucp1 expression and were less physically active than rats heterozygous for the mutation (Mc4r(+/K314X)) or wild-type (Mc4r(+/+)) rats, we found no evidence of lowered EE in Mc4r(K314X/K314X) rats once body weight was taken into account using covariance...

Primary hypoadrenocorticism, also known as Addison's disease, is an autoimmune disorder leading to the destruction of the adrenal cortex and subsequent loss of glucocorticoid and mineralocorticoid hormones. The disease is prevalent in Standard Poodles and is believed to be highly heritable in the breed. Using genotypes derived from the Illumina Canine HD SNP array, we performed a genome-wide association study of 133 carefully phenotyped Standard Poodles (61 affected, 72 unaffected) and found no markers significantly associated with the disease...

BACKGROUND: Rod fracture is a common complication of growing rods and can result in loss of correction, patient discomfort, and unplanned revision surgery. The ability to quantitate rod integrity at each lengthening would be advantageous to avoid this complication. We investigate the feasibility of applying structural health monitoring to evaluate the integrity of growing rods in vitro. METHODS: Single-rod titanium 4.5-mm growing rod constructs (n = 9), one screw proximally and one distally connected by in-line connectors, were assembled with pedicle screws fixed in polyethylene blocks...

: The effect of clinic-based intensive hypertension treatment on ambulatory blood pressure (BP) is unknown. The goal of the SPRINT (Systolic Blood Pressure Intervention Trial) ambulatory BP ancillary study was to evaluate the effect of intensive versus standard clinic-based BP targets on ambulatory BP. Ambulatory BP was obtained within 3 weeks of the 27-month study visit in 897 SPRINT participants. Intensive treatment resulted in lower clinic systolic BP (mean difference between groups=16...

Addison N Desnoyer, Jennifer A Love
Chemical transformations that result in either the formation or cleavage of carbon-heteroatom bonds are among the most important processes in the chemical sciences. Herein, we present a review on the reactivity of well-defined, late-transition metal complexes that result in the making and breaking of C-N, C-O and C-S bonds via fundamental organometallic reactions, i.e. oxidative addition, reductive elimination, insertion and elimination reactions. When appropriate, emphasis is placed on structural and spectroscopic characterization techniques, as well as mechanistic data...

Welma Pieterse, John S Terblanche, Pia Addison
Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) has shown remarkable range expansion over the past 10years and invaded several new continents including Africa. Here we report results of a detailed assessment of acute high and low temperature survival ability and the plasticity thereof, to test the hypothesis that traits of the thermal niche have contributed to the species' invasion ability. We also assess life-stage-related variation of thermal tolerances to determine potential stage-related environmental sensitivity...

Despite current antimicrobial stewardship programs (ASPs) being advocated by infectious disease specialists and discussed by national and international policy makers, ASPs coverage remains limited to only certain hospitals as well as specific service lines within hospitals. The ASPs incorporate a variety of strategies to optimize antimicrobial agent use in the hospital, yet the exact set of interventions essential to ASP success remains unknown. Promotion of ASPs across clinical practice is crucial to their success to ensure standardization of antimicrobial agent use within an institution...

Salivary cortisol has been used to monitor hydrocortisone replacement in patients with Addison's disease (AD). Since salivary cortisol is metabolised to salivary cortisone, it may be an adjunctive analyte to assess adequacy of hydrocortisone replacement in patients with AD. We aimed to characterise the exposure of salivary cortisol and cortisone in patients and healthy controls. We measured salivary cortisol and cortisone by liquid chromatography-tandem mass spectrometry and constructed a day curve (08:00 until 24:00 h) with 16 time points in 25 AD patients taking their usual hydrocortisone dose and in 26 healthy controls...
