Two-dimensional (2D) layered materials are ideal for micro- and nanoelectromechanical systems (MEMS/NEMS) due to their ultimate thinness. Platinum diselenide (PtSe2 ), an exciting and unexplored 2D transition metal dichalcogenides (TMD) material, is particularly interesting because its scalable and low temperature growth process is compatible with silicon technology. Here, we explore the potential of thin PtSe2 films as electromechanical piezoresistive sensors. All experiments have been conducted with semi-metallic PtSe2 films grown by thermally assisted conversion of Pt at a CMOS-compatible temperature of 400°C...

Hydrologic soil groups (HSGs) are a fundamental component of the USDA curve-number (CN) method for estimation of rainfall runoff; yet these data are not readily available in a format or spatial-resolution suitable for regional- and global-scale modeling applications. We developed a globally consistent, gridded dataset defining HSGs from soil texture, bedrock depth, and groundwater. The resulting data product-HYSOGs250m-represents runoff potential at 250 m spatial resolution. Our analysis indicates that the global distribution of soil is dominated by moderately high runoff potential, followed by moderately low, high, and low runoff potential...

In a referendum on 23nd June 2016 the people of the UK voted to leave the European Union (EU). The phenomenon known as Brexit did not come out of nowhere: according to Clarke, Whiteley and Goodwin (2017), it marked a culmination of social and political trends emerging over many years. Moreover, there is resonance far beyond the UK, with tensions between an increasingly globalised society and national autonomy, between young and old, and between 'liberals' and 'authoritarians' (Ford & Goodwin, 2014). Such forces underlie not just Brexit, but also, in different context and in different forms, the election of Donald Trump and the rise of populist parties in Europe...

The incidence of urothelial carcinoma (UC; formerly transitional cell carcinoma) is higher among renal transplant recipients compared with the general population. Upper urinary tract UC (UUT-UC) of allograft urothelium is a rare event with approximately 40 cases reported in the literature. Herein, we describe the clinical presentation and management of UUT-UC in a transplant ureter 10 years after deceased donor kidney transplantation.

The glutamatergic modulator ketamine has striking and rapid antidepressant effects in major depressive disorder (MDD), but its mechanism of action remains unknown. Proton magnetic resonance spectroscopy (1H-MRS) is the only non-invasive method able to directly measure glutamate levels in vivo; in particular, glutamate and glutamine metabolite concentrations are separable by 1H-MRS at 7T. This double-blind, placebo-controlled, crossover study that included 1 H-MRS scans at baseline and at 24 h post ketamine and post-placebo infusions sought to determine glutamate levels in the pregenual anterior cingulate (pgACC) of 20 medication-free MDD subjects and 17 healthy volunteers (HVs) 24 h post ketamine administration, and to evaluate any other measured metabolite changes, correlates, or predictors of antidepressant response...

Purple urine bag syndrome (PUBS) is a rare and striking manifestation associated with urinary tract infection involving bright purple discoloration of the lining and tubing of a urinary catheter bag. We present the interesting case of a 90-year-old female patient who developed PUBS and include a review of the relevant literature to date. Uniquely, in this case, PUBS acts as an important clinical sign in supporting the diagnosis of urinary tract infection in a high-risk patient.

The massive dynein motor complexes that drive ciliary and flagellar motility require cytoplasmic preassembly, a process requiring dedicated dynein assembly factors (DNAAFs). How DNAAFs interact with molecular chaperones to control dynein assembly is not clear. By analogy with the well-known multifunctional HSP90-associated cochaperone, R2TP, several DNAAFs have been suggested to perform novel R2TP-like functions. However, the involvement of R2TP itself (canonical R2TP) in dynein assembly remains unclear. Here we show that in Drosophila melanogaster , the R2TP-associated factor, Wdr92, is required exclusively for axonemal dynein assembly, likely in association with canonical R2TP...

BACKGROUND: Here we present an in-depth characterization of the mechanism of sequencer-induced sample contamination due to the phenomenon of index swapping that impacts Illumina sequencers employing patterned flow cells with Exclusion Amplification (ExAmp) chemistry (HiSeqX, HiSeq4000, and NovaSeq). We also present a remediation method that minimizes the impact of such swaps. RESULTS: Leveraging data collected over a two-year period, we demonstrate the widespread prevalence of index swapping in patterned flow cell data...

Most biomedical data repositories issue locally-unique accessions numbers, but do not provide globally unique, machine-resolvable, persistent identifiers for their datasets, as required by publishers wishing to implement data citation in accordance with widely accepted principles. Local accessions may however be prefixed with a namespace identifier, providing global uniqueness. Such "compact identifiers" have been widely used in biomedical informatics to support global resource identification with local identifier assignment...

BACKGROUND: Failure to restore femoral offset in metal on polyethylene total hip arthroplasty (THA) causes polyethylene wear and aseptic loosening. To our knowledge, no study to date has investigated the relationship between femoral offset and wear in metal-on-metal (MOM) THA. AIMS: In this study, we investigated the relationship between femoral offset and wear by measuring circulating metal ion levels in MOM THA. METHODS: In this retrospective study, we identified patients who had undergone MOM THA with the ASR XL system (DePuy International Ltd...

REVIEW
Niall A Smyth, Amiethab A Aiyer
Hallux valgus is a common pathology of the foot and ankle. Surgical correction of the condition has been described as early as 1836. Since then, numerous different surgical techniques have been documented in the literature. One of the explanations as to why there are so many different surgeries for hallux valgus is the variety of etiologies attributed to causing the condition. This article discusses the etiologies associated with hallux valgus and describes a few of the surgeries commonly used to treat the deformity...

Existing research evidence suggests that both music listening and mindfulness interventions may have beneficial effects on mood and cognition poststroke. This mixed-methods study, nested within a pilot randomized controlled trial investigating the feasibility and acceptability of combining music listening and brief mindfulness training poststroke, explored study participants' experiences of engaging in the interventions. Fifty-six stroke survivors who were randomized to receive an 8-week intervention of mindful music listening (n = 15), music listening (n = 21), or audiobook listening (n = 20, control) using self-selected material participated in a postintervention individual semistructured interview with a researcher not involved in their intervention delivery...

BACKGROUND: In supine patients with acute respiratory distress syndrome, the lung typically partitions into regions of dorsal atelectasis and ventral aeration ("baby lung"). Positive airway pressure is often used to recruit atelectasis, but often overinflates ventral (already aerated) regions. A novel approach to selective recruitment of dorsal atelectasis is by "continuous negative abdominal pressure." METHODS: A randomized laboratory study was performed in anesthetized pigs...

Amyotrophic Lateral Sclerosis is a neurodegenerative disorder characterized primarily by motor network disruption. Extra-motor manifestations including executive functions, social cognition, and behavioral changes are now well recognized as important features of ALS, and are associated with frontotemporal and frontostriatal network disruption. However, the presence and characterization of language changes has received less attention. This systematic review characterizes the profile of reported language dysfunction in ALS...

It is well-known that the neuropeptide oxytocin plays a critical role regulating the formation of adult-adult pairbonds in non-human animals, and recent work suggests oxytocin may similarly play an important role in romantic bonding in humans. Specifically, endogenous oxytocin is predictive of a host of relationship-enhancing behaviors, relationship quality, and even relationship survival amongst newly dating couples. This work suggests that oxytocin can buffer romantic relationships, possibly during especially difficult transition periods...

Fat accumulates in bone marrow (BM) of diabetic patients. Here, we investigated the mechanisms and consequences of this phenomenon. BM-mesenchymal stromal cells (BM-MSCs) from type-2 diabetic (T2D) patients constitutively express adipogenic markers and robustly differentiate into adipocytes (ADs) upon in-vitro induction as compared with BM-MSCs from non-diabetic subjects. Moreover, T2D BM adipocytes paracrinally stimulate a transcriptional adipogenic program in BM-MSCs. Antagonism of monocyte chemoattractant protein (MCP-1), a chemokine pivotally expressed in T2D BM-ADs, prevented the TD2 BM-AD secretome from converting BM-MSCs into ADs...
