Many young people place alcohol-related posts on social networking sites (SNS) which can result in undesirable effects. Although several recent studies have investigated the occurrence of alcohol-related SNS use, it is neither clear (a) what type of alcohol posts are placed on SNS, (b) the motivations to place alcohol posts, nor (c) which young people are most likely to place alcohol posts. This study addressed these three goals. A large cross-sectional study among young participants (12-30 years; N = 561) assessed the posting of different types of alcohol posts, the motivations to (not) post these posts, and potential differences in posting between subgroups (i...

PURPOSE: Sentinel node biopsy (SNB) after neoadjuvant therapy (NAT) for breast cancer remains controversial. We conducted a retrospective study of patients who underwent SNB after NAT to evaluate the effectiveness of this procedure. METHODS: A consecutive 105 women with locally advanced breast cancer (cT1-4, cN0-3, M0) were treated with NAT between 2006 and 2015. The subjects were 80 of these patients who became or remained clinically node-negative after NAT, 53 of whom had axillary management determined by SNB (group A) and the other 27 underwent axillary lymph node dissection (ALND) without SNB (group B)...

Netrins, chemotropic guidance cues, can guide the extension of serotonergic axons by binding to netrin receptors during neural development. However, little is known about whether disruption of netrin signaling is involved in the mechanisms by which organophosphorus pesticides affect serotonergic nervous system (SNS) development. In this study, we evaluated the effects of the pesticide monocrotophos (MCP) on the expression patterns of HpNetrin and its receptor neogenin as well as on the intracellular calcium ion (Ca(2+)) levels in Hemicentrotus pulcherrimus (sea urchin) by exposing fertilized embryos to 0, 0...

Single-layer phosphorene-like MX sheets have aroused new interest and could become a family of nanomaterials in physics and materials science. Using a first-principles method combined with non-equilibrium Green's function (NEGF) theory, we study the electronic transport properties of the zigzag phosphorene-like MX (M = Ge/Sn, X = S/Se) nanostructures. The results demonstrate that GeS and GeSe nanoribbons display very similar electronic transport properties. Their current-voltage (I-V) curves exhibit an interesting negative differential resistive (NDR) effect and are insensitive to their ribbon widths due to their similar band structures...

Excessive smartphone use causes personal and social problems. To address this issue, we sought to derive usage patterns that were directly correlated with smartphone dependence based on usage data. This study attempted to classify smartphone dependence using a data-driven prediction algorithm. We developed a mobile application to collect smartphone usage data. A total of 41,683 logs of 48 smartphone users were collected from March 8, 2015, to January 8, 2016. The participants were classified into the control group (SUC) or the addiction group (SUD) using the Korean Smartphone Addiction Proneness Scale for Adults (S-Scale) and a face-to-face offline interview by a psychiatrist and a clinical psychologist (SUC = 23 and SUD = 25)...

BACKGROUND: There are two lymphatic flows in lower rectal cancer; one along the inferior mesenteric artery and another towards the internal iliac artery. The benefit of dissection of lateral pelvic (LP) lymph nodes (LPLN) remains controversial. This study aimed to clarify the possibility of detecting the sentinel node (SN) of the LP region (LPSN) and examine metastasis, including micrometastasis, using a radio isotope (RI) method. METHODS: In total, 62 patients with clinical (c)T1-T4 rectal cancer were enrolled in this study (11, 16 and 35 patients had tumor located in the upper, middle and lower rectal third, respectively)...

Novel SnS/BiOI heterostructures with excellent photocatalytic degradation of methyl orange were successfully prepared by a facile hydrothermal-coprecipitation method. The maximum methyl orange degradation activity under visible light irradiation (λ>400nm) was found for 10wt% SnS/BiOI. The composite also showed better stability and good recyclability compared to BiOI. The energy band diagram and band offsets from X-ray photoelectron spectroscopy investigation indicated that the novel composite was a type-II heterojunction where the photogenerated electron-hole can be efficiently separated and transferred...

Currently, the most accurate method for identifying lymph node metastasis is intraoperative diagnosis by sentinel node (SN) biopsy. Based on the SNNS study-a recent large-scale, nationwide, multicenter prospective study-the SN concept seems to be scientifically valid in patients with early gastric cancer. SN biopsy is a multistep technique consisted of six essential elements: indication, the selection of a tracer, a proper tracer injection method, the objective detection of SNs, a reliable biopsy technique, and the precise detection of nodal metastasis...

The most prevalent single-nucleotide substitution (SNS) found in cancers is a C-to-T substitution in the CpG motif. It has been proposed that many of these SNSs arise during organismal aging, prior to transformation of a normal cell into a precancerous/cancer cell. Here, we isolated single intestinal crypts derived from normal tissue or from adenomas of Apc(min/+) mice, expanded them minimally in vitro as organoids, and performed exome sequencing to identify point mutations that had been acquired in vivo at the single-cell level...

A novel two-step solution approach is put forward to design a unique three dimensional (3D) porous ZnO-SnS p-n heterojunction under mild conditions. This special 3D structure is induced via flower-like ZnO in which SnS serves as an efficient photosensitizer to improve the light harvesting across the whole visible range. A profound investigation of the mechanism shows that this 3D porous ZnO-SnS material effectively integrates the large surface area and high redox potential of ZnO, and wide visible-light harvesting of SnS, which largely promotes the transfer and separation rate of carriers...

BACKGROUND Despite literature supporting the efficiency of percutaneous balloon kyphoplasty (PKP) in treating osteoporotic and malignant vertebral compression fractures, few reports exist that document its use for treatment of symptomatic Schmorl's nodes (SNs) refractory to conservative treatment. Patients with symptomatic SNs could have pain in the vertebrae similar to an acute vertebral compression fracture. MRI is very helpful in diagnosing symptomatic SNs when x-ray and CT scan are unremarkable. In painful cases, the vertebrae bone marrow around the SNs is hyperintense on T2-weighted subsequence...

BACKGROUND: The sympathetic nervous system (SNS) regulates glucose metabolism in various organs including the kidneys. The sodium glucose cotransporter 2 (SGLT2) mediates glucose reabsorption in renal proximal tubules and its inhibition has been shown to improve glucose control, cardiovascular and renal outcomes. We hypothesized that SNS-induced alterations of glucose metabolism may be mediated via regulation of SGLT2. METHOD: We used human renal proximal tubule cells to investigate the effects of noradrenaline on SGLT2 regulation...

Labor migrants are at an increased risk for poor mental health. Post-migration stressors contribute significantly to this risk. Social network supports are vitally important to protect health but little is known about the role of social network supports among labor migrants. The current study evaluated the role of migration stressors on poor mental health among Filipino female domestic workers (FDW) and whether family and friend social network support (SNS) modified this relationship. Data were collected from 261 FDWs in Macau, China from May to September 2013...

BACKGROUND: Lipolysis is stimulated by activation of adrenergic inputs to adipose tissues. Our recent study showed that serum concentrations of fatty acid binding protein 4 (FABP4) are robustly elevated in patients with acute myocardial infarction and ventricular tachyarrhythmia, that display a marked activation of the sympathetic nervous system (SNS). However, it remains unknown whether circulating FABP4 concentrations are associated with exercise-induced SNS activation. METHODS: Thirty one healthy volunteers underwent cardiopulmonary exercise testing on a cycle ergometer up to the workload levels below and above anaerobic threshold, low- and high-intensity exercise, respectively...

We identified 27 stable loci associated with agronomic traits in spring wheat using genome-wide association analysis, some of which confirmed previously reported studies. GWAS peaks identified in regions where no QTL for grain yield per se has been mapped to date, provide new opportunities for gene discovery and creation of new cultivars with desirable alleles for improving yield and yield stability in wheat. We undertook large-scale genetic analysis to determine marker-trait associations (MTAs) underlying agronomic and physiological performance in spring wheat using genome-wide association studies (GWAS)...

Social networking sites (SNSs) are social platforms that facilitate communication. For adolescents, peers play a crucial role in constructing the self online through displays of group norms on SNSs. The current study investigated the role of online social identity (OSI) in the relationship between adolescent exposure to alcohol-related content posted by peers on SNSs and alcohol use. In a sample (N = 929) of Australian adolescents (Age M = 17.25, SD = 0.31) higher levels of exposure to alcohol-related content on SNSs was associated with higher levels of alcohol use...

Cannabinoid hyperemesis syndrome (CHS), a variant of cyclic vomiting syndrome, is an enigmatic and challenging clinical disorder. As cannabis legalization, use, and potency has increased worldwide over the past decade, so has the prevalence of CHS. These patients often require acute care and inpatient treatment for refractory emesis, electrolyte derangement, dehydration, acute renal failure, and injury to the upper gastrointestinal tract. Routinely-prescribed antiemetics are frequently associated with treatment failure in CHS, necessitating use of sedating agents such as benzodiazepines and antipsychotics...
