Youth Access to Indoor Tanning Salons in Urban Versus Rural/Suburban Communities.

Research suggests that youth proximity to tanning salons may promote use, however little is known about tanning salon proximity to schools. We assessed the proximity of tanning salons to schools in urban versus rural/suburban communities across Worcester County, Massachusetts (population > 800K). To put findings in context, we compared school proximity to tanning salons to school proximity to McDonald's restaurants, a large franchise that also caters to young people. Accessibility was measured by ArcGIS 1...

Young drivers and their cars: Safe and sound or the perfect storm?

Consistent with the experiences in high-income countries, young drivers remain overrepresented in road trauma statistics in low- and middle-income countries. This article pursues the emerging interest of approaching the young driver problem from a systems thinking perspective in order to design and deliver robust countermeasures. Specifically, the focus of this paper is the cars driven by young drivers. The study of vehicles' characteristics and their interaction with driving behaviour is, more often than n...

Yolk-shell magnetic mesoporous TiO2 microspheres with flowerlike NiO nanosheets for highly selective enrichment of phosphopeptides.

In this work, we fabricated a yolk-shell magnetic composite that contains mesoporous TiO2 as the inner shell and flowerlike NiO as the outer shell (denoted as Fe3O4@H-TiO2@f-NiO) to reduce the limitations of single-component metal oxides in phosphopeptide enrichment. The NiO nanosheets play a synergistic role in phosphopeptide enrichment. And the unique flowerlike structure of NiO with sufficient space can facilitate the reversible insertion/extraction of peptides, which will have less impact on the enrichm...

Yersinia pestis strains of ancient phylogenetic branch 0.ANT are widely spread in the high-mountain plague foci of Kyrgyzstan.

Fifty six Yersinia pestis strains, isolated over the period of more than 50 years in three high-mountain foci of Kyrgyzstan (Tien Shan, Alai, and Talas), have been characterized by means of PCR and single nucleotide polymorphism (SNP) typing methods. Seven of these strains were also characterized by means of whole genome sequencing and genome-wide SNP phylogenetic analysis. It was found that forty two strains belong to 0.ANT2, 0.ANT3 and 0.ANT5 phylogenetic branches. From these, strains of 0.ANT2 and 0.ANT3...

Y chromosome in Turner syndrome.

Turner syndrome (TS) is an inherited genetic disorder caused by numerical and/or structural chromosome X aberrations occurring at a frequency of 1:1200-1:2500 live-born girls. The most common karyotype is X chromosome monosomy (45,X) (approximately 50-60% of cases). Approximately 5-6% of patients may have abnormal Y chromosome or mosaicism characterized by the coexistence of 45,X cell line with cell line in which all or part of chromosome Y is present. In patients with TS who have all or fragmented genetic ...

Yasui Conversion for Repair After Left Ventricular Outflow Tract Obstruction.

We herein report two cases of progressive left ventricular outflow obstruction after primary repair of arch obstruction and ventricular septal defect that was successfully resolved with Yasui conversion. Patients who require surgical reintervention for progressive left ventricular outflow tract (LVOT) obstruction after primary biventricular repair of interruption of the aortic arch or coarctation of the aorta complex are occasionally experienced. The modified Konno procedure and Ross operation are well reco...

Yeast Killer Toxin K28: Biology and Unique Strategy of Host Cell Intoxication and Killing.

The initial discovery of killer toxin-secreting brewery strains of Saccharomyces cerevisiae (S. cerevisiae) in the mid-sixties of the last century marked the beginning of intensive research in the yeast virology field. So far, four different S. cerevisiae killer toxins (K28, K1, K2, and Klus), encoded by cytoplasmic inherited double-stranded RNA viruses (dsRNA) of the Totiviridae family, have been identified. Among these, K28 represents the unique example of a yeast viral killer toxin that enters a sensitiv...

Yosprala®: A Fixed Dose Combination of Aspirin and Omeprazole.

Cardiovascular disease is the leading cause of morbidity and mortality in the United States. Patients who survive a primary cerebrovascular or cardiovascular event are at increased risk of a subsequent occurrence. Antiplatelet therapy plays an essential role for secondary prevention in individuals with stroke, transient ischemic attack, acute or chronic artery disease or peripheral arterial disease. Maintaining high risk patients on low dose aspirin therapy is a fundamental component of management. However,...

Yeast Srs2 Helicase Promotes Redistribution of Single-Stranded DNA-Bound RPA and Rad52 in Homologous Recombination Regulation.

Srs2 is a super-family 1 helicase that promotes genome stability by dismantling toxic DNA recombination intermediates. However, the mechanisms by which Srs2 remodels or resolves recombination intermediates remain poorly understood. Here, single-molecule imaging is used to visualize Srs2 in real time as it acts on single-stranded DNA (ssDNA) bound by protein factors that function in recombination. We demonstrate that Srs2 is highly processive and translocates rapidly (∼170 nt per second) in the 3'→5' d...

YEASTRACT: an upgraded database for the analysis of transcription regulatory networks in Saccharomyces cerevisiae.

The YEAst Search for Transcriptional Regulators And Consensus Tracking (YEASTRACT-www.yeastract.com) information system has been, for 11 years, a key tool for the analysis and prediction of transcription regulatory associations at the gene and genomic levels in Saccharomyces cerevisiae. Since its last update in June 2017, YEASTRACT includes approximately 163000 regulatory associations between transcription factors (TF) and target genes in S. cerevisiae, based on more than 1600 bibliographic references; it a...

You Wouldn't Sober, You Shouldn't Drunk: A Behavioural Change Approach to Changing Attitudes and Responses to Unwanted Sexual Attention in Pubs and Clubs.

The objective was to evaluate a campaign designed to influence social norms and re-establish boundaries around the issue of unwanted sexual attention in pubs and clubs. In particular, the campaign aimed to raise awareness, and reduce the acceptability, of unwanted sexual attention when drunk.

YUCCA9-mediated Auxin Biosynthesis and Polar Auxin Transport Synergistically Regulate Regeneration of Root Systems Following Root Cutting.

Recovery of the root system following physical damage is an essential issue for plant survival. An injured root system is able to regenerate by increases in lateral root (LR) number and acceleration of root growth. The horticultural technique of root pruning (root cutting) is an application of this response and is a common garden technique for controlling plant growth. Although root pruning is widely used, the molecular mechanisms underlying the subsequent changes in the root system are poorly understood. I...

Youngswick-Austin versus distal oblique osteotomy for the treatment of Hallux Rigidus.

Hallux Rigidus is the most common degenerative joint pathology of the foot. Several procedures are described for the management of this deformity. In this prospective study we compared Youngswick-Austin and distal oblique osteotomy in the treatment of grade II Hallux Rigidus, in terms of clinical outcomes, efficacy and complications.

Yeast-template synthesized Fe-doped cerium oxide hollow microspheres for visible photodegradation of acid orange 7.

Fe-doped cerium oxide (CeO2) hollow microspheres were successfully synthesized by a simple co-precipitation route using yeast asa bio-template and nitrate as the oxide precursor. The products were characterized by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, N2 adsorption-desorption isotherms and UV-Vis diffuse reflectance spectroscopy. It was found that the products had a well-defined ellipsoidal morphology and the size of the hollow microspheres was about 1.5-2.5μm. ...

Yellow Fever Vaccine Shortages in the United States and Abroad: A Critical Issue.

Y Not? Sex Chromosomes May Modify Sexual Dimorphism in Pulmonary Hypertension.

Yellow fever virus, but not Zika or Dengue virus inhibits T cell receptor-mediated T cell function by an RNA-based mechanism.

The Flavivirus genus within the Flaviviridae is comprised of many important human pathogens including Yellow Fever virus (YFV), Dengue virus (DENV) and Zika virus (ZKV), all of which are global public health concerns. Although the related flaviviruses hepatitis C virus and human pegivirus (formerly named GBV-C) interfere with T cell receptor (TCR) signaling by novel RNA and protein based mechanisms, the effect of other flaviviruses on TCR signaling is unknown. Here, we studied the effect of YFV, DENV, and Z...

Yeast Creates a Niche for Symbiotic Lactic Acid Bacteria through Nitrogen Overflow.

Many microorganisms live in communities and depend on metabolites secreted by fellow community members for survival. Yet our knowledge of interspecies metabolic dependencies is limited to few communities with small number of exchanged metabolites, and even less is known about cellular regulation facilitating metabolic exchange. Here we show how yeast enables growth of lactic acid bacteria through endogenous, multi-component, cross-feeding in a readily established community. In nitrogen-rich environments, Sa...

Yeast community in traditional Portuguese Serpa cheese by culture-dependent and -independent DNA approaches.

This study investigated the yeast community present in the traditional Portuguese cheese, Serpa, by culture-dependent and -independent methods. Sixteen batches of Serpa cheeses from various regional industries registered with the Protected Designation of Origin (PDO) versus non-PDO registered, during spring and winter, were used. Irrespective of the producer, the yeast counts were around 5log CFU/g in winter and, overall, were lower in spring. The yeast species identified at the end of ripening (30days), us...

Yoga, mindfulness-based stress reduction and stress-related physiological measures: A meta-analysis.

Practices that include yoga asanas and mindfulness-based stress reduction for the management of stress are increasingly popular; however, the neurobiological effects of these practices on stress reactivity are not well understood. Many studies investigating the effects of such practices fail to include an active control group. Given the frequency with which people are selecting such interventions as a form of self-management, it is important to determine their effectiveness. Thus, this review investigates t...
