Copper(ii) complexes [Cu(L1)(H2O)2](SO3CF3)21 and [Cu(L2)(H2O)2](SO3CF3)22 based on 2,6-bis(benzimidazolyl)pyridine were synthesized and are reported herein as highly selective "turn-on" optical probes for l-cysteine. The Cu(ii)/Cu(i) redox potential of probe 1 (0.14 V vs. NHE) was lower than that of 2 (0.233 V vs. NHE) in water. The molecular structure of 2 adopted a square pyramidal geometry (τ = 0.2545), with the Cu-Npy bond (1.958 Å) of its middle pyridine unit being shorter than the other two Cu-Nbenzim bonds (Cu-N, 1...

Bin-Bin Chen
Within the theoretical framework of attachment theory, the author examined associations between adolescents' procrastination and their attachment relationships with both mothers and fathers, and explored the potential mediation role of self-worth in these associations. Participants were 384 Chinese adolescents (49.6% boys, average age 15.13 years) from public schools in Shanghai, China. They completed self-report measures of 3 dimensions of parental attachment (i.e., trust, communication, and alienation), general self-worth, and procrastination...

BACKGROUND: Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-β (TGF-β) superfamily. Recently, BMP7 has been demonstrated to be produced by salivary glands and contribute to embryonic branching in mice. The BMP7 in saliva is thought to be delivered to the oral cavity and is expected to contact with stratified squamous epithelial cells which line the surface of oral mucosa. In this study, we attempted to investigate the effects of BMP7 on oral epithelial cells...

A quantitative risk assessment was conducted to assess the risk of human salmonellosis acquired from consumption of pecans in the United States. The model considered the potential for Salmonella survival, growth, and recontamination of pecans from the sheller to the consumer, including steps such as immersion in water, drying, conditioning, cracking, partitioning, and storage. Five theoretical microbial reduction treatment levels (1 to 5 log CFU) were modeled. Data from the 2010 to 2013 surveys by the National Pecan Shellers Association were used for initial prevalence and contamination levels...

The stereoselective reagent-controlled homologation of boronic esters is one of a small number of iteratable synthetic transformations that if automated could form the basis of a veritable molecule-making machine. Recently, α-stannyl triisopropylbenzoates and α-sulfinyl chlorides have emerged as useful building blocks for the iterative homologation of boronic esters. However, α-stannyl benzoates need to be prepared using stoichiometric amounts of the (+)- or (-)-enantiomer of the scarcely available and expensive diamine sparteine; also, these building blocks, together with the byproducts that are generated during homologation, are perceived as being toxic...

The end-Devonian to mid-Mississippian time interval has long been known for its depauperate palaeontological record, especially for tetrapods. This interval encapsulates the time of increasing terrestriality among tetrapods, but only two Tournaisian localities previously produced tetrapod fossils. Here we describe five new Tournaisian tetrapods (Perittodus apsconditus, Koilops herma, Ossirarus kierani, Diploradus austiumensis and Aytonerpeton microps) from two localities in their environmental context...

It's good news to recruit more nurses, but now plan the retention bit (news, 9 August). Professionals deserve more. I suggest a 55% rise for nurses and 35% rise for junior doctors. Senior clinical staff should raise staff establishments to safe levels. Not ministers.

BACKGROUND: Mandated college students (those in violation of a campus alcohol policy) are heterogenous with respect to alcohol consumption. Thus, when universities consider required treatment for mandated students, one promising option is to match treatment intensity according to level of alcohol involvement. The present study evaluates such an approach with minimal resources. METHODS: Mandated students (N = 285) were required to complete a baseline assessment. Participants identified as high-risk (5+ past month alcohol problems AND 2+ past month heavy drinking episodes) received a one session individual Brief Motivational Intervention (I-BMI) whereas those identified as low-risk (all others) received a one session group Brief Motivational Intervention (G-BMI)...

In addition to having proper energy levels and high hole mobility (μh) without the use of dopants, hole-transporting materials (HTMs) used in n-i-p-type perovskite solar cells (PSCs) should be processed using green solvents to enable environmentally friendly device fabrication. Although many HTMs have been assessed, owing to the limited solubility of HTMs in green solvents, no green-solvent-processable HTM has been reported to date. Here we report on a green-solvent-processable HTM, an asymmetric D-A polymer (asy-PBTBDT) that exhibits superior solubility even in the green solvent, 2-methylanisole, which is a known food additive...

Chronic non-specific widespread pain (CWP) including fibromyalgia (FMS) is characterized by widespread pain, reduced pain threshold, and multiple tender points on examination, causing disability and decreased quality of life. Vitamin D has been proposed as an associated factor in CWP. This meta-analysis aimed to explore the benefit of vitamin D supplementation in the management of CWP. A comprehensive search of the CENTRAL, MEDLINE, and Embase databases was performed from inception through January 2017. The inclusion criterion was the randomized clinical trials' evaluating the effects of vitamin D treatment in adult subjects with CWP or FMS...

Neuroinflammatory response in spinal dorsal horn has been demonstrated to be a critical factor in oxaliplatin-induced pain. Melatonin has been shown to have anti-inflammatory and anti-allodynia effects in both preclinical and clinical studies. In the present study, we investigated the role of systemic administration of melatonin on oxaliplatin-induced pain. Intraperitoneal (i.p.) injection with oxaliplatin induced significantly mechanical allodynia and thermal hyperalgesia. Melatonin (i.p.) significantly alleviated mechanical allodynia and thermal hyperalgesia in the oxaliplatin but not sham-treated rats...

Hyponatremia is associated with bone demineralization. We hypothesized that, during hyponatremia, calciuria and calcium balance depend on volemic status. We evaluated calciuria in patients with hyponatremia, secondary to SIAD or hypovolemia. Patients with SIAD exhibited a volemic expansion that was associated with hypercalciuria. Calciuria was proportional to markers of volemia. INTRODUCTION: Chronic mild hyponatremia has been associated with bone demineralization of unknown mechanisms...

Gaucher disease (GD) is caused by mutations on the GBA1 gene leading to deficiency in acid β-glucosidase (GCase) and subsequent accumulation of its substrates, glucosylceramide (GlcC) and glucosylsphingosine (GlcS). GlcS in plasma has been proposed as a highly sensitive and specific biomarker for the diagnosis of GD and for monitoring disease progression and response to therapy. Here we report a novel robust and accurate hydrophilic interaction liquid chromatography tandem mass spectrometric method (HILIC-MS/MS) for the direct measurement of glucosylsphingosine (GlcS) in dried plasma spots (DPS)...

Concussions are a major cause of morbidity in pediatrics. Many concussions occur during activities with emergency medical service (EMS) providers present to determine if a higher level of care is needed. Data are limited on how capable these providers are. We assessed the ability of EMS providers to recognize pediatric concussions. Fifty-six total responses were included, 38 from EMS and 18 from our MD/RN (medical doctor/registered nurse) group. No statistical differences were found between the 2 groups when adjusted for age, gender, number of years in practice, and number of pediatric concussions managed...

OBJECTIVE: Frataxin (FXN) is a highly conserved mitochondrial protein. Reduced FXN levels cause Friedreich ataxia, a recessive neurodegenerative disease. Typical patients carry GAA repeat expansions on both alleles, while a subgroup of patients carry a missense mutation on one allele and a GAA repeat expansion on the other. Here, we report that selected disease-related FXN missense mutations impair FXN localization, interaction with mitochondria processing peptidase, and processing. METHODS: Immunocytochemical studies and subcellular fractionation were performed to study FXN import into the mitochondria and examine the mechanism by which mutations impair FXN processing...

Rehmannia glutinosa polysaccharide (RGP) has shown an activation of immune cells in vitro. However, the immune stimulatory effect of RGP in a mouse in vivo is not well studied. In this study, we examined the effect of RGP on dendritic cell (DC) activation and anticancer immunity in vivo. Treatments of RGP in C56BL/6 mice induced increased levels of co-stimulatory molecule expression and pro-inflammatory cytokine production in spleen DCs dependent on toll-like receptor 4 (TLR4), and those DCs promoted interferon-gamma (IFNγ) production in CD4(+) and CD8(+) T cells...
