High quality single crystal ZrSiS as a theoretically predicted Dirac semimetal has been grown successfully using a vapor phase transport method. The single crystals of tetragonal structure are easy to cleave into perfect square-shaped pieces due to the van der Waals bonding between the sulfur atoms of the quintuple layers. Physical property measurement results including resistivity, Hall coefficient (RH), and specific heat are reported. The transport and thermodynamic properties suggest a Fermi liquid behavior with two Fermi pockets at low temperatures...

During oogenesis, hundreds of maternal RNAs are selectively localized to the animal or vegetal pole, including determinants of somatic and germline fates. Although microarray analysis has identified localized determinants, it is not comprehensive and is limited to known transcripts. Here, we utilized high-throughput RNA-sequencing analysis to comprehensively interrogate animal and vegetal pole RNAs in the fully grown Xenopus laevis oocyte. We identified 411 (198 annotated) and 27 (15 annotated) enriched mRNAs at the vegetal and animal pole, respectively...

1.Estimating how much long-distance migrant populations spread out and mix during the non-breeding season (migratory connectivity) is essential for understanding and predicting population dynamics in the face of global change. 2.We quantify variation in population spread and inter-population mixing in long-distance, terrestrial migrant land-bird populations (712 individuals from 98 populations of 45 species, from tagging studies in the Neotropic and Afro-Palearctic flyways). We evaluate the Mantel test as a metric of migratory connectivity, and explore the extent to which variance in population spread can be explained simply by geography...

Bariatric surgery, such as vertical sleeve gastrectomy (VSG), causes remarkable improvements in cardiometabolic health, including hypertension remission. However, the mechanisms responsible remain undefined and poorly studied. Therefore, we developed and validated the first murine model of VSG that recapitulates the blood pressure lowering effect of VSG using gold-standard radiotelemetry technology. We used this model to investigate several potential mechanisms, including body weight, brain endoplasmic reticulum (ER) stress signaling and brain inflammatory signaling, all critical contributors to obesity-associated hypertension pathogenesis...

Recent evidence has implicated the transmembrane co-receptor neuropilin-1 (NRP1) in cancer progression. Primarily known as a regulator of neuronal guidance and angiogenesis, NRP1 is also expressed in multiple human malignancies, where it promotes tumor angiogenesis. However, non-angiogenic roles of NRP1 in tumor progression remain poorly characterized. In this study, we define NRP1 as an androgen-repressed gene whose expression is elevated during the adaptation of prostate tumors to androgen-targeted therapies (ATTs), and subsequent progression to metastatic castration-resistant prostate cancer (mCRPC)...

INTRODUCTION: Executive function deficits are prevalent in people with multiple sclerosis (PwMS), and PwMS use less adaptive coping than healthy controls. This cross-sectional study assessed whether there is a relationship between executive function and coping in PwMS. METHOD: One hundred and seven participants with relapsing remitting or secondary progressive MS (n = 83 and 24, respectively; age M = 48.8 ± 11.1 years) completed measures of coping and executive function...

A plausible mechanism underlying flavonoid-associated cognitive effects is increased cerebral blood flow (CBF). However, behavioural and CBF effects following flavanone-rich juice consumption have not been explored. The aim of this study was to investigate whether consumption of flavanone-rich juice is associated with acute cognitive benefits and increased regional CBF in healthy, young adults. An acute, single-blind, randomised, cross-over design was applied with two 500-ml drink conditions - high-flavanone (HF; 70·5 mg) drink and an energy-, and vitamin C- matched, zero-flavanone control...

The aim of this study was to assess contemporary management of slipped capital femoral epiphysis (SCFE) by surveying members of the British Society of Children's Orthopaedic Surgery (BSCOS). A questionnaire with five case vignettes was used. Two questions examined the timing of surgery for an acute unstable SCFE in a child presenting at 6 and 48 h after start of symptoms. Two further questions explored the preferred method of fixation in mild and severe stable SCFE. The final question examined the management of the contralateral normal hip...

REVIEW
Thomas Butler
Within 24 hours after antibiotic treatment of the spirochetal infections syphilis, Lyme disease, leptospirosis, and relapsing fever (RF), patients experience shaking chills, a rise in temperature, and intensification of skin rashes known as the Jarisch-Herxheimer reaction (JHR) with symptoms resolving a few hours later. Case reports indicate that the JHR can also include uterine contractions in pregnancy, worsening liver and renal function, acute respiratory distress syndrome, myocardial injury, hypotension, meningitis, alterations in consciousness, seizures, and strokes...

OBJECTIVES: Creatine kinase (CK) is a sensitive enzyme marker for muscle damage in athletes. Elevated CK levels have been reported in many endurance physical activities. The consequence and possible long-term sequela of the CK elevation in athletes is unknown. There is a paucity of literature stating actual numerical values of CK associated with competing in an ultramarathon with extreme environmental conditions. Our hypothesis was that the serum CK levels increase significantly as a result of running a 161km ultramarathon at high altitude...

BACKGROUND: Aerobic capacity, as measured by peak oxygen uptake (V[Combining Dot Above]O2), is one of the most powerful predictors of prognosis in heart failure (HF). Inflammation is a key factor contributing to alterations in aerobic capacity, and interleukin (IL)-1 cytokines are implicated in this process. The adaptor protein ASC is necessary for inflammasome activation of IL-1β and IL-18. ASC expression is controlled through epigenetic modification; lower ASC methylation is associated with worse outcomes in HF...

OBJECTIVES: Brief guided parent-delivered cognitive behaviour therapy (CBT) has been developed to meet the demand for non-intensive interventions for children with anxiety disorders, and initial trials have shown it to be effective for children with a range of anxiety disorders. This study examined outcomes 3-5 years post-treatment. DESIGN: A long-term follow-up (LTFU) cohort study. METHODS: Families who (1) completed at least 50% of allocated treatment sessions of guided parent-delivered CBT for childhood anxiety as part of a randomized control trial (RCT), (2) provided consent to be recontacted, (3) had not received further mental health interventions, and (4) were contactable were invited to take part...

The preparation and applications of heterobimetallic complexes continue to occupy researchers in the fields of organometallic, main group, and coordination chemistry. This interest stems from the promise these complexes hold as precursors to materials, reagents in synthesis and as new catalysis. Here we survey and organise the state-of-the-art understanding of the TM-H-M linkage (M = Mg, Zn, Al, Ga). We discuss the structure and bonding in these complexes, their known reactivity, and their largely unrealised potential in catalysis...

PURPOSE: In 2009, the American Society for Radiation Oncology (ASTRO) published consensus recommendations that stated ductal carcinoma in situ (DCIS) patients were in a "cautionary" group for accelerated partial breast irradiation (APBI) and should not receive APBI outside of a clinical trial. However, very recently, ASTRO placed low-risk DCIS patients in the "suitable" category. Given this recent change, we aimed to use the Surveillance, Epidemiology, and End Results (SEER) database to evaluate past patterns of implantable APBI (IAPBI) utilization in women with DCIS...
