You are what you eat: Gut microbiota determines kin recognition in Drosophila.

Gut bacteria is now considered as an additional host organ, and it has been shown that they have important influences on host developmental and physiological processes. More recently gut bacteria have additionally been implicated in behavioral processes. We showed that in two species of Drosophila, gut bacteria variation affects behavior, altering partner investment in copulation in relation to whether individuals were familiar (i.e., having developed in the same environment), or were related. This suggests...


YIA1 Early Detection of the Process of Vascular Calcification with Spect-ct and Pet-ct using Novel Bone Seeking Radiopharmaceuticals in Rat Models.

Vascular calcification is considered to be a significant predictor of coronary heart disease. It is also associated with serious clinical complications such as left ventricular hypertrophy and calcific uremic arteriolopathy. Matrix vesicles and apoptotic bodies (AB's) released by calcifying vascular smooth muscle cells (VSMC's) form the nidus for calcification in the vessel wall. Electron beam computed tomography (EBCT), the gold standard for non-invasive imaging and quantitation of vascular calcification f...


YIA2 PMCA1 Deletion Leads to Increased Blood Pressure and Cardiac Hypertrophy.

Heart failure is the common and final end point of cardiovascular disease. Seventy four percent of congestive heart failure patients also suffer from hypertension. Genome wide association studies (GWAS) have recently identified mutations in the ATP2B1 gene as having a strong association with hypertension risk. The ATP2B1 gene encodes the calcium extrusion pump, plasma membrane calcium ATPase (PMCA1), which also functions as a signalling molecule. This project aims to examine the link between PMCA1 and blood...


YIA4 Genetic Risk Markers for Atrial Fibrillation Influence Allelic Expression of Nearby Candidate Genes.

: Genome-wide association studies (GWAS) have identified genetic variants in nine chromosomal regions that are associated with atrial fibrillation (AF). The mechanisms underlying these associations are unknown. To investigate these mechanisms, we mapped associations between single nucleotide polymorphisms (SNPs) and allelic expression of candidate genes in the region of interest.


YIA5 RGS-1 Regulates Leukocyte Trafficking in Atherosclerosis and Aortic Aneurysm Formation through Chemokine Receptor Desensitisation.

: The regulation of macrophage recruitment and retention into the vascular wall is critical in the progression of atherosclerosis and aortic aneurysm formation. This can be mediated by chemokine activation of multiple G-protein coupled receptors. The Regulator of G-Protein Signalling-1 (RGS-1) acts to deactivate the intracellular response to sustained chemokine stimulation. We have found that RGS-1 is up-regulated with atherosclerotic plaque progression and with monocyte-macrophage activation. However littl...

Yolk Sac Mesenchymal Progenitor Cells from New World Mice (Necromys lasiurus) with Multipotent Differential Potential.

Fetal membranes are abundant, ethically acceptable and readily accessible sources of stem cells. In particular, the yolk sac is a source of cell lineages that do not express MHCs and are mainly free from immunological incompatibles when transferred to a recipient. Although data are available especially for hematopoietic stem cells in mice and human, whereas other cell types and species are dramatically underrepresented. Here we studied the nature and differentiation potential of yolk sac derived mesenchymal...

Youth marijuana use: state of the science for the practicing clinician.

Despite widespread marijuana use among adolescents, accurate information on known health effects is poorly disseminated to clinicians and their patients. Amidst rapidly evolving drug policy in the United States and elsewhere, it is imperative that providers understand the short-term and long-term consequences of marijuana use.


Yacon (Smallanthus Sonchifolius): a food with multiple functions.

Abstract Functional foods are the focus of many studies worldwide. This is justified by the effects they have on public health and thus interest in elucidation of the mechanisms involved in their actions. The present review aims to broaden the discussions of the functional properties attributed to yacon (Smallanthus sonchifolius), considered a food with multiple functions since it possesses bioactive compounds (antimicrobial, antioxidant and probiotic substances) that exert beneficial effects on the body. A...


Young Children's Understanding of Denial.

Although a fair amount is known about young children's production of negation, little is known about their comprehension. Here, we focus on arguably the most complex basic form, denial, and how young children understand denial, when it is expressed in response to a question with gesture, single word, or sentence. One hundred twenty-six children in 3 age groups (Ms = 1 year 9 months, 2 years 0 months, and 2 years 4 months) witnessed an adult look into 1 of 2 buckets and then, in response to a question about ...

Yolk-sac-derived macrophages regulate fetal testis vascularization and morphogenesis.

Organogenesis of the testis is initiated when expression of Sry in pre-Sertoli cells directs the gonad toward a male-specific fate. The cells in the early bipotential gonad undergo de novo organization to form testis cords that enclose germ cells inside tubules lined by epithelial Sertoli cells. Although Sertoli cells are a driving force in the de novo formation of testis cords, recent studies in mouse showed that reorganization of the vasculature and of interstitial cells also play critical roles in testis...

Yeast Two-Hybrid System for Dissecting the Rice MAPK Interactome.

Protein-protein interactions are a preliminary but fundamental key to many biological systems. Identification of proteins that interact with particular bait not only contributes to a deeper understanding of bait protein function but also provides much information for the discovery of larger-scale interaction networks (interactome). Therefore, protein-protein interaction mapping is regarded as a widely accepted standardized functional genomics technique that provides comprehensive functional interpretation o...

Yeast phospholipid biosynthesis is linked to mRNA localization.

Localization of mRNAs and local translation are universal features in eukaryotes and contribute to cellular asymmetry and differentiation. In Saccharomyces cerevisiae, localization of mRNAs that encode membrane proteins requires the She protein machinery including the RNA-binding protein She2p as well as movement of the cortical endoplasmic reticulum (cER) to the yeast bud. In a screen for ER-specific proteins necessary for directional transport of WSC2 and EAR1 mRNAs, we have identified enzymes of the phos...

You are what you eat: fatty acid profiles as a method to track the habitat movement of an insect.

Tracking the movement of small organisms is of tremendous importance to understanding the ecology of populations, communities, and ecosystems. However, it remains one of the most difficult challenges facing the field of movement ecology. We developed an intrinsic marking technique for tracking small organisms using dietary fatty acid profiles as a biomarker as well as for clarifying source-sink dynamics between populations on a landscape level. Navel orangeworm moths (NOW), Amyelois transitella (Walker) (Le...

Yeast Phosphofructokinase-1 Subunit Pfk2p is Necessary for pH Homeostasis and Glucose-Dependent V-ATPase Reassembly.

V-ATPases are conserved ATP-driven proton pumps that acidify organelles. Yeast V-ATPase assembly and activity are glucose-dependent. Glucose depletion causes V-ATPase disassembly and its inactivation. Glucose re-addition triggers reassembly and resumes proton transport and organelle acidification. We investigated the roles of the yeast phosphofructokinase-1 subunits Pfk1p and Pfk2p for V-ATPase function. The pfk1Δ and pfk2Δ mutants grew on glucose and assembled wild-type levels of V-ATPase pumps at the me...
