Staphylococcus aureus (S. aureus) is one of the most common etiological agents in hospital-acquired infections and food-borne illness. S. aureus toxins and virulence proteases often circulate in host blood vessels leading to life-threatening diseases. Standard identification approaches include bacterial culturing method, which takes several days. Other nucleic acid-based methods were expensive and required trained personnel. To surmount these limitations, a paper-based biosensor was developed. The sensing mechanism was based on the proteolytic activity of S...

There is a growing consensus in the scientific community that suggests a strong association between obstructive sleep apnea (OSA) and cardiovascular (CVD) conditions and events, including coronary artery disease, hypertension, arrhythmia, heart failure, and sudden cardiac death. We reviewed evidence on the relationship between OSA and arrhythmia. Our conclusion, based on our review of the literature, is that the evidence supports a strong link between OSA and cardiovascular mortality, which warrants treating OSA...

Cu3(BTC)2 (BTC: 1,3,5-benzenetricarboxylic acid) showed to be an efficient and reusable heterogeneous solid catalyst for the formation of SiO bond through dehydrogenative coupling of dimethylphenylsilane (1) with phenol under mild reaction conditions. It is observed that Fe(BTC), MIL-101(Cr) and UiO-66(Zr) are not able to promote this cross coupling between 1 and phenol. Cu3(BTC)2 exhibits higher stability and activity compared to other MOFs studied here. Furthermore, Cu3(BTC)2 is reused for three consecutive cycles with a slight decay in its activity...

BACKGROUND AND OBJECTIVES: Adolescence-related increases in both anxiety and risk taking may originate in variability in Intolerance of Uncertainty (IU), rendering the study of IU of importance. We therefore studied the psychometric properties of the Intolerance of Uncertainty Scale-Short version (IUS-12), including its associations with trait anxiety and risk taking, among adolescents. METHODS: A sample of 879 Dutch adolescents, from diverse educational levels, and with an equal distribution of boys and girls, was classically tested...

Cesarean section rates have risen dramatically in China within the past 25 years, particularly driven by non-medical factors and maternal requests. One major reason women request cesareans is the fear of labor pain, in a country where a minority of women are given any form of pain relief during labor. Drawing upon ethnographic fieldwork and in-depth interviews with 26 postpartum women and 8 providers at a Shanghai district hospital in June and July of 2015, this article elucidates how perceptions of labor pain and the environment of pain relief constructs the cesarean on maternal request...

Qi-Yang Nie, Hermann J Müller, Markus Conci
When remembering a natural scene, both detailed information about specific objects and summary representations such as the gist of a scene are encoded. However, formal models of change detection that are used to estimate working memory capacity, typically assume observers simply encode and maintain memory representations that are treated independently from one another without considering the (hierarchical) object or scene structure. To overcome this limitation, we present a hierarchical variant of the change detection task that attempts to formalize the role of object structure, thus, allowing for richer, more graded memory representations...

Yoo Min Park, Mei-Po Kwan
This study aims to empirically demonstrate the necessity to consider both the spatiotemporal variability of air pollution and individual daily movement patterns in exposure and health risk assessment. It compares four different types of exposure estimates generated by using (1) individual movement data and hourly air pollution concentrations; (2) individual movement data and daily average air pollution data; (3) residential location and hourly pollution levels; and (4) residential location and daily average pollution data...

BACKGROUND: Standard treatment of advanced cervicovaginal cancer [international federation of gynecology and obstetrics (FIGO) stages II(B), III(A, B), IVA] is (chemo-)radiation excluding the possibility of systematic histopathological assessment of locoregional tumour spread. Laterally extended endopelvic resection (LEER) and therapeutic lymph node dissection (tLND) are novel surgical treatment options for advanced cervicovaginal cancer. METHODS: The therapeutic efficacy of LEER for locally advanced primary and recurrent cervicovaginal cancer was reassessed by an update of the prospective observational trial at the University of Leipzig...

Religion is an under-studied factor affecting children's sexual victimization and their willingness to discuss such experiences. In this qualitative study, 39 child forensic interviewers and child advocacy center (CAC) directors in the United States discussed religious influences on children's sexual abuse experiences, their relationships to CACs, and their disclosures in the forensic setting. Participants reported both harmonious and dissonant interactions between religiously observant children and families on one hand and child advocacy centers on the other...

This study was conducted to provide information on the genetic diversity of human parvovirus B19 (B19V) circulating in the municipality of Niterói, Rio de Janeiro, Southeast Brazil during 1996-2006, a period with two distinct outbreaks of B19V infection: 1999-2000 and 2004-2005. A total of 27 sera from patients with erythema infectiosum (EI) and five sera from HIV-infected patients that tested positive for B19V DNA during the study period were analyzed. To genotype B19V strains, a semi-nested PCR for partial amplification of the capsid gene was performed and sequence analysis revealed that 31 sequences belonged to subgenotype 1a (G1a) of the main genotype 1 and one sequence was characterized as subgenotype 3b (G3b)...

BACKGROUND: Despite changing sexual norms and mores generally perceived to be permissive of sexual expression, parents continue to serve as gateways to uptake of reproductive health services and commodities in our cultural settings. However, their support for adolescent uptake of human papilloma virus (HPV) vaccine are not well explored and documented. This study aims to assess parental knowledge and awareness of HPV infection and cervical cancer and their support for HPV vaccination for their adolescent children...

Plant-growth promoting rhizobacteria (PGPR) are studied as complements/alternatives to chemical fertilization in agriculture. Poor information however, exists on the potential of PGPR from undisturbed ecosystems. Here, we evaluated the plant growth-promoting (PGP) effect of rhizobacterial consortia from undisturbed Chilean arid-ecosystems (Consortium C1) and agro-ecosystems (Consortium C2) on plant biomass production. The PGP effects of C1 and C2 were assayed in wheat seedlings (Triticum aestivum L.) grown in pots under growth chamber conditions and in pots placed in an open greenhouse under natural conditions, using two different Chilean Andisols (Piedras Negras and Freire series) kept either at 30% or 60% of their maximum water holding capacity (MWHC)...

REVIEW
Valerie Diane V Valeriano, Marilen P Balolong, Dae-Kyung Kang
The use of lactobacilli as probiotics in swine has been gaining attention due to their ability to improve growth performance and carcass quality, prevent gastrointestinal infection, and most importantly, their 'generally recognised as safe' status. Previous studies support the potential of lactobacilli to regulate host immune systems, enhance gut metabolic capacities, and maintain balance in the gut microbiota. Research on swine gut microbiota has revealed complex gut microbial community structure and showed the importance of Lactobacillus to the host's health...

Adult neurogenesis supports performance in many hippocampal dependent tasks. Considering the small number of adult-born neurons generated at any given time, it is surprising that this sparse population of cells can substantially influence behavior. Recent studies have demonstrated that heightened excitability and plasticity may be critical for the contribution of young adult-born cells for certain tasks. What is not well understood is how these unique biophysical and synaptic properties may translate to networks that support behavioral function...

Leisure is an important quality of life factor for older Korean immigrants. The purpose of this study was to explore leisure benefits associated with health among older Korean immigrants. A total of 18 individuals participated in the study. Using interpretative phenomenological analysis (IPA), three themes emerged from participants' personal statements and experiences: (a) experiencing psychological benefits, (b) strengthening social connections, and (c) coping with acculturative stress. The findings indicate that leisure provided a context in which older Korean immigrants created an emotional and social support system that helped them to experience psychological and social benefits...
