Atomic Layer Deposition of Large-Area Polycrystalline Transition Metal Dichalcogenides from 100 °C through Control of Plasma Chemistry.

Two-dimensional transition metal dichalcogenides, such as MoS, are intensely studied for applications in electronics. However, the difficulty of depositing large-area films of sufficient quality under application-relevant conditions remains a major challenge. Herein, we demonstrate deposition of polycrystalline, wafer-scale MoS, TiS, and WS films of controlled thickness at record-low temperatures down to 100 °C using plasma-enhanced atomic layer deposition.

Mercury, selenium, and fatty acids in the axial muscle of largemouth bass: evaluating the influence of seasonal and sexual changes in fish condition and reproductive status.

Largemouth bass (LMB, 265-475 mm) were collected to document whether changes in fish condition and reproductive status influenced the concentration of total mercury (Hg) and selenium (Se) in axial muscle by season and sex. The fatty acid (FA) composition of fish was also examined to describe seasonal and sexual differences and identify whether arachidonic acid (ARA) could be used as a biomarker of Hg toxicity. There was a trend for females to have lower (p < 0.

Types and Treatment of Hair Loss in Men and Women.

In this article, the author focuses on 4 common hair loss disorders that occur in both men and women. The author discusses research related to androgenetic alopecia, telogen effluvium, alopecia areata, and scarring alopecia and provides details on how to approach and manage these diseases according to patient gender. There are a range of tools and tests that can assist with the diagnostic process and help ensure that relevant and high standards of patient care are maintained.

Revisiting the Evidence for the Reuse of Enteral Feeding Equipment in Ambulatory Patients: A Systematic Review.

Background: The reuse of enteral tube feeding (ETF) equipment is not recommended due to the risk of microbial contamination and subsequent risk of infection; however, this practice continues in many ambulatory settings. A systematic review of the literature was undertaken to review the evidence underpinning the cleaning and reuse of ETF equipment.

Methods: Studies that investigated the reuse, decontamination, and/or cleaning of ETF equipment were considered for inclusion.

Review of the Use of Platelet-Rich Plasma in the Treatment of Alopecia.

Platelet-rich plasma (PRP) therapy is a new approach in dermatology and there is evidence to suggest that it provides excellent adjuvant treatment for nonscarring alopecia cases. There is evidence supporting the hypothesis that PRP therapy increases hair growth and thickness in patients with nonscarring alopecia. Studies including participants with scarring alopecia are limited and larger scale studies with tighter controls in PRP preparation, administration, and follow-up are needed to determine whether this is a clinically sound approach.

An importance-performance analysis of hospital information system attributes: A nurses' perspective.

Purpose: Health workers have numerous concerns about hospital IS (HIS) usage. Addressing these concerns requires understanding the system attributes most important to their satisfaction and productivity. Following a recent HIS implementation, our objective was to identify priorities for managerial intervention based on user evaluations of the performance of the HIS attributes as well as the relative importance of these attributes to user satisfaction and productivity outcomes.

Sickle cell anemia: targeting the role of fetal hemoglobin in therapy.

Sickle cell anemia results from the single amino acid substitution of valine for glutamic acid in the beta-chain owing to a nucleotide defect that causes the production of abnormal beta-chains in hemoglobin S. Abnormal hemoglobin chains form polymers in the deoxygenated state, leading to the characteristic sickle cells. The polymerization of deoxygenated hemoglobin S accounts for the pathologic changes in sickle cell disease.

Clinical audit of subjects with snoring & sleep apnoea/hypopnoea syndrome fitted with mandibular repositioning splint.

Snoring and obstructive sleep apnoea/hypopnoea syndrome (OSAHS) are often treated with mandibular repositioning splints (MRS), but the efficacy and satisfaction of them has not been comprehensively addressed. A survey on the use of and satisfaction with MRS was posted to 177 patients referred by a hospital orthodontic department for custom-fitting of a MRS. Data were analysed using non-parametric techniques.

Sleep-disordered breathing as a risk factor for cerebrovascular disease: a case-control study in patients with transient ischemic attacks.

Background And Purpose: The evidence that obstructive sleep apnea/hypopnea (OSAH) is a risk factor for ischemic cerebrovascular disease is inconclusive. We explored this relationship in transient ischemic attack (TIA) patients because they are less likely than stroke patients to have OSAH as a consequence of cerebrovascular disease.

Methods: We performed a case-control study among 86 patients with TIA from a hospital neurovascular clinic, matched for age (+/-5 years) and sex with controls from the referring local family practice registers.

Randomized crossover trial of two treatments for sleep apnea/hypopnea syndrome: continuous positive airway pressure and mandibular repositioning splint.

Mandibular repositioning splints (MRSs) and continuous positive airway pressure (CPAP) are used to treat the sleep apnea/hypopnea syndrome (SAHS). There are some data suggesting that patients with milder symptoms prefer MRS, but there are few comparative data on outcomes. Therefore, we performed a randomized crossover trial of 8 weeks of CPAP and 8 weeks of MRS treatment in consecutive new outpatients diagnosed with SAHS (apnea/hypopnea index [AHI] >or= 5/hour, and >or= 2 symptoms including sleepiness).

Bispectral index values and spectral edge frequency at different stages of physiologic sleep.

Unlabelled: Bispectral index (BIS) and spectral edge frequency (SEF) are used as measures of depth of anesthesia and sedation. We tested whether these signals could predict physiologic sleep stages, by taking processed electroencephalogram measurements and recording full polysomnography through a night's sleep in 10 subjects being investigated for mild sleep apnea/hypopnea syndrome. Computerized polysomnograph signals were analyzed manually according to standard criteria, classifying each 30-s epoch as a specific sleep stage.
