Y-V alar base reduction.


Yeti, a Drosophila melanogaster essential gene, encodes a protein required for chromatin organization.

The evolutionarily conserved family of Bucentaur (BCNT) proteins exhibits a widespread distribution in animal and plants, yet its biological role remains largely unknown. Using Drosophila melanogaster as a model organism, we investigated the in vivo role of the Drosophila BCNT member called YETI. We report that loss of YETI causes lethality before pupation and defects in higher order chromatin organization, evidenced by severe impairment in the association of histone H2A.V, nucleosomal histones and epigenet...


Young commuters are most keen to choose an out of area GP.


You decides who decides: an online tool for choosing enduring powers of attorney.

The Office of the Public Advocate's (OPA) experience of enduring powers of attorney indicates that the crucial step of thinking about who to appoint as substitute decision-maker and considering the sorts of decisions those people are likely to make, is too often overlooked in the haste to get the documents in place. OPA saw the need for resources that encourage people to consider these issues as an important part of the process.

Yet Another Study Reports Poor Control of Elevated Blood Pressure.


Yeast AMP-Activated Protein Kinase Monitors Glucose Concentration Changes as well as Absolute Glucose Levels.

Analysis of the time-dependent behavior of a signaling system can provide insight into its dynamic properties. We employed the nucleo-cytoplasmic shuttling of the transcriptional repressor Mig1 as readout to characterize Snf1-Mig1 dynamics in single yeast cells. Mig1 binds to promoters of target genes and mediates glucose repression. Mig1 is predominantly located in the nucleus when glucose is abundant; upon glucose depletion Mig1 is phosphorylated by the AMP-activated kinase Snf1 and exported into the cyto...


Youth basketball specific effort test.


Young female athletes have changed considerably in the two years after baseline evaluation in a prospective study.

A 3-year prospective cohort study has been initiated in Japanese young female handball and basketball players to identify risk factors for non-contact ACL injuries. Although we examined the baseline data of the players at their first year of high school, it raises concern about the use of the individual baseline data as the characteristics of the players (might be identified as a risk factor) in cases where the players get injured during their senior year of high school.


Young onset dementia: The impact of emergent age-based factors upon personhood.

This paper evaluates how emergent age-based factors may impact upon the experience of dementia. A review of selected literature is undertaken to explore how personhood has been conceptualised in relation to dementia. It is then highlighted that very little literature explicitly addresses personhood with reference to young onset dementia. Young onset dementia is defined, and evaluation is then undertaken of the distinctive age-based factors that might shape the experience of the condition. It is noted that w...


YgaE regulates out membrane proteins in Salmonella enterica serovar Typhi under hyperosmotic stress.

Salmonella enterica serovar Typhi (S. Typhi) is a human-specific pathogen that causes typhoid fever. In this study, we constructed ΔygaE mutant and a microarray was performed to investigate the role of ygaE in regulation of gene expression changes in response to hyperosmotic stress in S. Typhi. qRT-PCR was performed to validate the microarray results. Our data indicated that ygaE was the repressor of gab operon in S. Typhi as in Escherichia coli (E. coli), though the sequence of ygaE is totally different f...


Young men with low birthweight exhibit decreased plasticity of genome-wide muscle DNA methylation by high-fat overfeeding.

The association between low birthweight (LBW) and risk of developing type 2 diabetes may involve epigenetic mechanisms, with skeletal muscle being a prime target tissue. Differential DNA methylation patterns have been observed in single genes in muscle tissue from type 2 diabetic and LBW individuals, and we recently showed multiple DNA methylation changes during short-term high-fat overfeeding in muscle of healthy people. In a randomised crossover study, we analysed genome-wide DNA promoter methylation in s...


Yerba mate enhances probiotic bacteria growth in vitro but as a feed additive does not reduce Salmonella Enteritidis colonization in vivo.

Yerba mate (Ilex paraguariensis) is a tea known to have beneficial effects on human health and antimicrobial activity against some foodborne pathogens. Thus, the application of yerba mate as a feed additive for broiler chickens to reduce Salmonella colonization was evaluated. The first in vitro evaluation was conducted by suspending Salmonella Enteritidis and lactic acid bacteria (LAB) in yerba mate extract. The in vivo evaluations were conducted using preventative and horizontal transmission experiments. I...


Yeast osmosensors hkr1 and msb2 activate the hog1 MAPK cascade by different mechanisms.

To cope with environmental high osmolarity, the budding yeast Saccharomyces cerevisiae activates the mitogen-activated protein kinase (MAPK) Hog1, which controls an array of osmoadaptive responses. Two independent, but functionally redundant, osmosensing systems involving the transmembrane sensor histidine kinase Sln1 or the tetraspanning membrane protein Sho1 stimulate the Hog1 MAPK cascade. Furthermore, the Sho1 signaling branch itself also involves the two functionally redundant osmosensors Hkr1 and Msb2...


Yeast Pah1p Phosphatidate Phosphatase is Regulated by Proteasome-mediated Degradation.

Yeast PAH1-encoded phosphatidate phosphatase is the enzyme responsible for the production of the diacylglycerol used for the synthesis of triacylglycerol that accumulates in the stationary phase of growth. Paradoxically, the growth phase-mediated inductions of PAH1 and phosphatidate phosphatase activity do not correlate with the amount of Pah1p; enzyme abundance declined in a growth phase-dependent manner. Pah1p from exponential phase cells was a relatively stable protein and its abundance was not affected...


Yeast telomere maintenance is globally controlled by programmed ribosomal frameshifting and the nonsense-mediated mRNA decay pathway.

We have previously shown that ~10% of all eukaryotic mRNAs contain potential programmed -1 ribosomal frameshifting (-1 PRF) signals and that some function as mRNA destabilizing elements through the Nonsense-Mediated mRNA Decay (NMD) pathway by directing translating ribosomes to premature termination codons. Here, the connection between -1 PRF, NMD and telomere end maintenance are explored. Functional -1 PRF signals were identified in the mRNAs encoding two components of yeast telomerase, EST1 and EST2, and...


Young People's Views on Accelerometer Use in Physical Activity Research: Findings from a User Involvement Investigation.

The use of accelerometers to objectively measure physical activity is important in understanding young people's behaviours, as physical activity plays a key part in obesity prevention and treatment. A user-involvement qualitative study with young people aged 7-18 years (n = 35) was carried out to investigate views on accelerometer use to inform an obesity treatment research study. First impressions were often negative, with issues related to size and comfort reported. Unwanted attention from wearing an ac...

Y Choromosomal Microdeletion Screening in The Workup of Male Infertility and Its Current Status in India.

Spermatogenesis is an essential stage in human male gamete development, which is regulated by many Y chromosome specific genes. Most of these genes are centred in a specific region located on the long arm of the human Y chromosome known as the azoospermia factor region (AZF). Deletion events are common in Y chromosome because of its peculiar structural organization. Astonishingly, among the several known genetic causes of male infertility, Y chromosomal microdeletions emerged as the most frequent structural...


Young stroke patients are at high risk for subsequent end-stage renal disease: a population-based observational study.

An increased incidence of end-stage renal disease (ESRD) in stroke patients has not been confirmed. The aim of this population-based study was to examine the risk of ESRD in stroke patients in Taiwan.

The aim of this work was to study the yeast populations and the main hygienic-sanitary microbial indicators in water buffalo mozzarella produced and commercialized in Minas Gerais, Brazil. Forty-two water buffalo mozzarella samples were purchased from retail outlets in Belo Horizonte. In addition, five samples of consecutive starter cultures, curd before acidification, acidified curd and mozzarella were collected at an industry in the city of Oliveira. Only three of the five water samples analyzed were suit...


Yessotoxin induces ER-stress followed by autophagic cell death in glioma cells mediated by mTOR and BNIP3.

Yessotoxin at nanomolar concentrations can induce programmed cell death in different model systems. Paraptosis-like cell death induced by YTX in BC3H1 cells, which are insensitive to several caspase inhibitors,has also been reported. This makes yessotoxin of interest in the search of molecules that target cancer cells vulnerabilities when resistance to apoptosis is observed. To better understand the effect of this molecule at the molecular level on tumor cells, we conducted a transcriptomic analysis using 3...
