Hydrogen Sulfide Splitting into Hydrogen and Sulfur through Off-Field Electrocatalysis.

Hydrogen sulfide (HS), a toxic gas abundant in natural gas fields and refineries, is currently being removed mainly via the Claus process. However, the emission of sulfur-containing pollutants is hard to be prevented and the hydrogen element is combined to water. Herein, we report an electron-mediated off-field electrocatalysis approach (OFEC) for complete splitting of HS into H and S under ambient conditions.

Rh(III)-Catalyzed Synthesis of 3-Amino-4-arylisoquinolinones from 4-Diazoisochroman-3-imines and N-Methoxybenzamides.

A Rh(III)-catalyzed reaction of N-methoxybenzamides and 4-diazoisochroman-3-imines is described. This method offers a rapid entry to 3-amino-4-arylisoquinolinone architectures from readily available starting materials under mild reaction conditions. A one-pot cascade C-H bond activation/formal [4 + 2] cycloaddition mechanism is proposed.

Changes of soil physical and chemical properties of albic soil in the meadow of Sanjiang Plain after rice planting.

The changes and renewal of soil quality are the criteria for judging agricultural development and soil management. The albic soil is the main paddy field soil in Sanjiang Plain. There is limited knowledge about the changes of soil quality after the dry field was changed into the paddy field.

Massive cortical reorganization is reversible following bilateral transplants of the hands: evidence from the first successful bilateral pediatric hand transplant patient.

In this repeated measures case study, we show that sensory deafferentation after limb amputation leads to changes in cortical somatotopic maps which are reversible after restoration of sensory input. Using magnetoencephalography (MEG), we observed in a child with bilateral hand transplants large-scale shifts in somatosensory lip cortical representation from anatomic hand area to anatomic face region. After recovery of tactile sensation in the digits, responses to finger stimulation were localized to orthotopic sensory cortex, but with atypical electrophysiologic features (amplitude and frequencies).

The potential of Second Life for university counseling: a comparative approach examining media features and counseling problems.

This study explored the potential of Second Life (SL), a popular multi-user virtual online environment, for university counseling. University students ( = 312) were asked to evaluate three counseling channels (i.e.

Nicotinic excitation of serotonergic projections from dorsal raphe to the nucleus accumbens.

Tobacco use is a major public health problem, and although many smokers report that they want to quit, only a small percentage succeed. Side effects associated with nicotine withdrawal, including depression, anxiety, and restlessness, certainly contribute to the low success rate. The dorsal raphe nucleus (DRN) is a serotonergic center with many functions, including control of mood and emotional state.

Optimal timing in screening patients with congestive heart failure and healthy subjects during circadian observation.

Congestive heart failure (CHF) is a major medical challenge in developed countries. In order to screen patients with CHF and healthy subjects during circadian observation, accurate judgment and fast response are imperative. In this study, optimal timing during circadian observation via the heart rate variability (HRV) was sought.

Bupropion inhibits the cellular effects of nicotine in the ventral tegmental area.

Each year, tobacco use causes over 4 million deaths worldwide and billions of dollars are spent on treatment for tobacco-related illness. Bupropion, an atypical antidepressant, improves the rates of successful smoking cessation, however, the mechanisms by which bupropion reduces cigarette smoking and depression are unknown. Here we show that clinical concentrations of bupropion inhibit nicotine's stimulatory effects on brain reward areas.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) in the Irish population.

Objective: To determine the Irish prevalence of autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), the AIRE mutations involved and clinical features of this population.

Methods: All patients were identified through paediatricians and endocrinologists in Ireland. Patients were invited to attend a multidisciplinary clinic.

Mental health histories and psychiatric medication usage among persons who sought cosmetic Surgery.

This retrospective chart review study examined the mental health histories and psychiatric medication usage of persons who sought cosmetic surgery. The medical records of 232 patients who had undergone a consultation for a cosmetic procedure were reviewed. The rates of self-reported psychiatric disorders and of psychiatric medication usage of these patients were compared with those of 200 patients who underwent noncosmetic procedures.

Purification and molecular characterization of cGMP-dependent protein kinase from Apicomplexan parasites. A novel chemotherapeutic target.

The trisubstituted pyrrole 4-[2-(4-fluorophenyl)-5-(1-methylpiperidine-4-yl)-1H-pyrrol-3-yl]pyridine (Compound 1) inhibits the growth of Eimeria spp. both in vitro and in vivo. The molecular target of Compound 1 was identified as cGMP-dependent protein kinase (PKG) using a tritiated analogue to purify a approximately 120-kDa protein from lysates of Eimeria tenella.
