#1
Loghman Golbaghi, Mehrdad Khamforoush, Tahmasb Hatami
The sugarcane bagasse was used for producing carboxymethyl cellulose (CMC) and obtaining high-molecular-mass hemicellulose as co-product. To this end, the steam explosion process was employed. It was found that the optimum operating conditions are the temperature of 187.15°C, NaOH/bagasse ratio of 39% (w/w), and retention time (RT) of 10min. Next, the obtained cellulose in the optimized condition was extracted and purified, and it was subsequently converted to CMC according to Williamson etherification technique...

The α-oxoaldehyde methylglyoxal is a ubiquitous and highly reactive metabolite known to be involved in aging- and diabetes-related diseases. If not detoxified by the endogenous glyoxalase system, it exerts its detrimental effects primarily by reacting with biopolymers such as DNA and proteins. We now demonstrate that during ketosis, another metabolic route is operative via direct non-enzymatic aldol reaction between methylglyoxal and the ketone body acetoacetate, leading to 3-hydroxyhexane-2,5-dione. This novel metabolite is present at a concentration of 10%-20% of the methylglyoxal level in the blood of insulin-starved patients...

PURPOSE: To compare minimally invasive strabismus surgery (MISS) with conventional strabismus surgery for horizontal recti in terms of functional outcome and complications. METHODS: A total of 40 patients requiring surgery for horizontal recti were divided into two groups: those undergoing MISS and those operated on using the conventional limbal technique. In the MISS group, two small keyhole radial cuts were made superior and inferior to the insertion of the muscle margin...

Ignasi Cos
How effort is internally quantified and how it influences both movement generation and decisions between potential movements are 2 difficult questions to answer. Physical costs are known to influence motor control and decision-making, yet we lack a general, principled characterization of how the perception of effort operates across tasks and conditions. Morel and colleagues introduce an insightful approach to that end, assessing effort indifference points and presenting a quadratic law between perceived effort and force production...

Entomological measures of transmission are important metrics specified by the World Health Organization to document the suppression and interruption of transmission of Onchocerca volvulus, the causative agent of onchocerciasis. These metrics require testing of large numbers of vector black flies. Black fly collection has relied on human landing collections, which are inefficient and potentially hazardous. As the focus of the international community has shifted from onchocerciasis control to elimination, replacement of human landing collections has become a priority...

This article combines qualitative and quantitative textual approaches to the representation of penis size and sexual position of performers in ten of the most visited gay pornography websites currently in operation. Specifically, in excess of 6,900 performer profiles sourced from ten commercial websites are analysed. Textual analysis of the profile descriptions is combined with a quantitative representation of disclosed penis size and sexual position, which is presented visually by two figures. The figures confirm that these sites generally market themselves as featuring penises that are extraordinarily large, and finds a sample-wide correlation between smaller penis sizes (5-6...

This study evaluated psychometric properties of interview, self-report, and screening versions of the Child PTSD Symptom Scale for DSM-5 (CPSS-5), a measure of posttraumatic stress disorder (PTSD) for traumatized youth based on DSM-5 criteria. Participants were 64 children and adolescents (51.6% female, 45.3% African American/Black) between 8 and 18 years of age (M = 14.1, SD = 2.5) who had experienced a DSM-5 Criterion A trauma. Participants completed test-retest procedures for the self-report and interviewer versions of the CPSS-5 in 2 visits that were up to 2 weeks apart...

Photoconductive antennas are widely used for time-resolved detection of THz pulses. In contrast to photothermoelectric or bolometric THz detection, the coherent detection allows direct measurement of the electric field transient of a THz pulse, which contains both, spectral and phase information. In this letter we demonstrate for the first time photoconductive detection of free-space propagating THz radiation with thin flakes of a van der Waals material. Mechanically exfoliated flakes of black phosphorus are combined with an antenna that concentrates the THz fields to the small flake (~10 μm)...

Papillary fibroelastomas (PFEs) are rare and benign cardiac tumors which usually are localized on the valves (mostly on the aortic valve), though they may originate also from the ventricles or atrial walls. Whilst, in the large majority of cases, these lesions are asymptomatic they may cause serious complications such as thromboembolic events, or more rarely valvular dysfunctions. Surgical excision is necessary for a symptomatic lesion. The management of asymptomatic lesions is not defined. Herein are reported the details of a miniseries of six cases operated on at the authors' institution between 2005 and 2015...

Herein, we report a single step, anionic surfactant-assisted, low temperature-hydrothermal synthetic strategy of CoO nanoparticles anchored on β-Co(OH)2 nanosheets which show a low overpotential (295 mV @ 10 mA cm(-2)) for the oxygen evolution reaction (OER). They also demonstrate much better kinetic parameters compared to the state-of-the-art RuO2. Interestingly, under the OER operational conditions (in alkaline medium), the topotactic transformation of α-Co(OH)2 to a stable Brucite-like β-Co(OH)2 phase leads to a synergistic interaction between the β-Co(OH)2 sheets on the CoO nanoparticles for enhancing the OER electrocatalytic activity...

Chemosynthetic Fe-oxidizing communities are common at diffuse-flow hydrothermal vents throughout the world's oceans. The foundational members of these communities are the Zetaproteobacteria, a class of Proteobacteria that is primarily associated with ecosystems fueled by ferrous iron, Fe(II). We report here the discovery of two new isolates of Zetaproteobacteria isolated from the Mid-Atlantic Ridge (TAG-1), and the Mariana back-arc (SV-108), that are unique in that they can utilize either Fe(II) or molecular hydrogen (H2) as sole electron donor and oxygen as terminal electron acceptor for growth...
