Cannabis use disorder (CUD) co-occurs with anxiety disorders at high rates. Little is known about the mechanisms linking CUD and anxiety disorders. One theoretically-driven perspective is that individuals with anxiety disorders may be more apt to use FSBs (i.e., behaviors that may be effective in decreasing anxiety in the short-term, but can maintain and even exacerbate anxiety in the long-term), which can perpetuate cannabis use despite cannabis-related problems. The present study tested whether FSB use explained the relation of anxiety symptom severity with cannabis quantity and related problems among 77 adults with CUD and comorbid anxiety disorders seeking outpatient CUD treatment...

Genetic rescue can reduce inbreeding depression and increase fitness of small populations, even when the donor populations are highly inbred. In a recent experiment involving two inbred island populations of the South Island robin, Petroica australis, reciprocal translocations improved microsatellite diversity and individual fitness. While microsatellite loci may reflect patterns of genome-wide diversity, they generally do not indicate the specific genetic regions responsible for increased fitness. We tested the effectiveness of this reciprocal translocation for rescuing diversity of two immunogenetic regions: toll-like receptor (TLR) and major histocompatibility complex (MHC) genes...

INTRODUCTION: The value of imaging the deep branch of the ulnar nerve (DBUN) over its entire course has not been clarified. Therefore, this study aimed to evaluate the feasibility of visualizing the DBUN from its origin to the most distal point. METHODS: We performed high-resolution ultrasound (HRUS) with high-frequency probes (18-22MhZ), HRUS-guided ink-marking, and consecutive dissection in 8 fresh cadaver hands. In both hands of 10 healthy volunteers (n=20), the cross-sectional area (CSA) was measured at 2 different locations (R1+R2)...

BACKGROUND AND OBJECTIVES: Treatment satisfaction can be improved by integrating patients' preferences into shared decision-making. We recently investigated patients' preferences for attributes of biologicals, and showed high preferences for safety and efficacy. The objective of the present study was to assess the impact of treatment experience on these preferences. PATIENTS AND METHODS: Preferences for outcome (probability of 50 % and 90 % improvement, time until response, sustainability of success, probability of mild and severe adverse events, probability of ACR 20 response) and process attributes (treatment location, frequency, duration, and delivery method) were analyzed in 200 participants with moderate-to-severe psoriasis using conjoint analysis...

REVIEW
Tom Norris, Bradley N Manktelow, Lucy K Smith, Elizabeth S Draper
Few high-income countries have an active national programme of stillbirth audit. From the three national programmes identified (UK, New Zealand, and the Netherlands) steady declines in annual stillbirth rates have been observed over the audit period between 1993 and 2014. Unexplained stillbirth remains the largest group in the classification of stillbirths, with a decline in intrapartum-related stillbirths, which could represent improvements in intrapartum care. All three national audits of stillbirths suggest that up to half of all reviewed stillbirths have elements of care that failed to follow standards and guidance...

Sonam V Sancheti, Parag R Gogate
Palladium-catalyzed Suzuki-Miyaura cross-coupling reaction is a significant reaction for obtaining industrially important products. The current research work deals with intensification of reaction of 4-bromoanisole and phenylboronic acid catalyzed with 5wt% Pd/C (5% by weight Pd supported on C available as commercial catalyst) using ultrasound and more importantly, without use of any additional phase transfer catalyst. Heterogeneous catalyst has been selected in the present work so as to harness the benefits of easy separation and the possible limitations of heterogeneous operation are minimized by introducing ultrasonic irradiations...

Isocitrate dehydrogenase 1 (IDH1) mutations in gliomas have been associated with a frontal lobe location and a greater proportion of noncontrast-enhancing tumour (nCET). The purpose of our study was to validate the utility of MRI imaging features in predicting IDH1 mutations in glioblastomas. Pre-operative MRIs of new glioblastoma patients, consisting of at least FLAIR and T1-weighted post-contrast sequences, were reviewed by a neuroradiologist based primarily on the VASARI feature set. IDH1 mutation testing was performed on all patients using immunohistochemistry...

Emma Kanbar, Damien Fouan, Charles A Sennoga, Alexander A Doinikov, Ayache Bouakaz
Subharmonic signals backscattered from gas-filled lipid-shelled microbubbles have generated significant research interest because they can improve the detection and sensitivity of contrast-enhanced ultrasound imaging. However, the emission of subharmonic signals is strongly characterized by a temporal dependence, the origins of which have not been sufficiently elucidated. The features that influence subharmonic emissions need to be identified not only to better develop next-generation microbubble contrast agents, but also to develop more efficient subharmonic imaging (SHI) modes and therapeutic strategies...

BACKGROUND & AIMS: Recent research has suggested that dietary fructose intake may increase serum uric acid (UA) concentrations. Both UA concentration and fructose consumption maybe also increase in NAFLD. It is not known whether dietary fructose consumption and UA concentration are independently associated with non-alcoholic steatohepatitis (NASH). Our aim was to investigate the factors associated with NASH in children and adolescents with proven NAFLD, and to test whether UA concentrations and fructose consumption are independently associated with NASH...

The frequency of sexual victimization in high-risk populations like adolescents in institutional care has hardly been studied. In this study, we report lifetime prevalence and incidence from a nationwide German sample including 322 adolescents (mean age 16.69 years, 43% female) from 20 residential care facilities and 12 boarding schools. Lifetime prevalence for severe sexual victimization (in and outside of institution) was 46.7% for girls and 8.0% for boys. Moreover, 5% of all adolescents experienced severe sexual victimization for the first time after they were admitted to the current institution (mean duration of stay in the current institution 3...

Manashita Borah, Binoy Krishna Roy
This paper presents an interesting phenomenon unobserved so far in literature to the best of the authors' knowledge in fractional-order chaotic systems (FOCSs). It is the rotational phenomenon of fractional-order coexisting attractors. Another significant feature of the newly proposed FOCS is that two 2-wing chaotic attractors coexist in its fractional-order dynamics i.e. α<1. But once the system attains integer-order, the two attractors merge and evolve into a single 4-wing attractor. Furthermore, the authors have drawn its comparison with various well-known FOCSs to prove its superior features...
