Yield and cold storage of Trichoderma conidia is influenced by substrate pH and storage temperature.

In this study we examined the influence of the ambient pH during morphogenesis on conidial yield of Trichoderma sp. "atroviride B" LU132 and T. hamatum LU593 and storage at low temperatures. The ambient pH of the growth media had a dramatic influence on the level of Trichoderma conidiation and this was dependent on the strain and growth media. On malt-extract agar, LU593 yield decreased with increasing pH (3-6), whereas yield increased with increasing pH for LU132. During solid substrate production the reve...

YopE specific CD8+ T cells provide protection against systemic and mucosal Yersinia pseudotuberculosis infection.

Prior studies indicated that CD8+ T cells responding to a surrogate single antigen expressed by Y. pseudotuberculosis, ovalbumin, were insufficient to protect against yersiniosis. Herein we tested the hypothesis that CD8+ T cells reactive to the natural Yersinia antigen YopE would be more effective at providing mucosal protection. We first confirmed that immunization with the attenuated ksgA- strain of Y. pseudotuberculosis generated YopE-specific CD8+ T cells. These T cells were protective against challeng...

Young adulthood cognitive ability predicts statin adherence in middle-aged men after first myocardial infarction: A Swedish National Registry study.

Background Cognitive ability (CA) is positively related to later health, health literacy, health behaviours and longevity. Accordingly, a lower CA is expected to be associated with poorer adherence to medication. We investigated the long-term role of CA in adherence to prescribed statins in male patients after a first myocardial infarction (MI). Methods CA was estimated at 18-20 years of age from Military Conscript Register data for first MI male patients (≤60 years) and was related to the one- and two-ye...

Yasui procedure.

There are rare situations in which the left ventricular outflow tract cannot be used for systemic output. The Yasui procedure allows leaving the left ventricle as the systemic ventricle, but uses the pulmonary valve as the systemic semilunar valve. These videos illustrate the technical aspects of the Yasui procedure.

YPC-21661 and YPC-22026, novel small molecules, inhibit ZNF143 activity in vitro and in vivo.

Zinc-finger protein 143 (ZNF143) is a transcription factor that is involved in anticancer drug resistance and cancer cell survival. In the present study, we identified a novel small molecule N-(5-bromo-2-methoxyphenyl)-3-(pyridine-3-yl) propiolamide (YPC-21661) that inhibited ZNF143 promoter activity and down-regulated the expression of the ZNF143-regulated genes, RAD51, PLK1, and Survivin, by inhibiting the binding of ZNF143 to DNA. In addition, YPC-21661 was cytotoxic and induced apoptosis in the human co...

Yeast alter micro-oxygenation of wine: Oxygen consumption and aldehyde production.

Micro-oxygenation (MOx) is a common winemaking treatment used to improve red wine color development and diminish vegetal aroma among other effects. It is commonly applied to wine immediately after yeast fermentation (phase 1) or later, during aging (phase 2). While most winemakers avoid MOx during malolactic (ML) fermentation, it is often not possible to avoid as ML bacteria are often present during phase 1 MOx treatment. We investigated the effect of common yeast and bacteria on the outcome of micro-oxygen...

Young and Lean: Elimination of Senescent Cells Boosts Adaptive Thermogenesis.

Thermogenesis converts the chemical energy of nutrients into heat, and this is associated to improved metabolic performance. In a previous issue of Cell Metabolism, Berry et al. (2017) reported that the progenitors of thermogenic beige adipocytes lose functionality with aging, and this process can be reversed with strategies that eliminate senescent cells.

Yupingfeng Powder relieves the immune suppression induced by dexamethasone in mice.

Yupingfeng Powder (YPF), a Chinese medical formula, is used traditionally for allergic diseases and characterized by reducing allergy relapse. In the present study, we attempted to investigate the effect of YPF on the immunity of mice and the possible mechanisms.

Yeast populations evolve to resist CdSe quantum dot toxicity.

Engineered nanomaterials are used globally in biomedical, electronic, and optical devices, and are often discarded into the environment. Cell culture experiments have shown that many inorganic nanoparticles are toxic to eukaryotic cells. Here, we show that populations of eukaryotic cells can evolve to survive chronic exposure to toxic CdSe semiconductor quantum dots (QDs). We grew yeast Saccharomyces cerevisiae for 24 days in liquid medium containing QDs prepared daily at half the minimum inhibitory concent...

Young women with HIV infection acquired by vertical transmission: Expectations of having uninfected children.

Pediatric antiretroviral therapy (ART), changed the prognosis of the disease, allowing young women infected by vertical transmission (TV) to be pregnant without risk for their fetus of acquiring this infection.

Years of Experience as a Predictor of Nurse Faculty Technology Use.

Many nurse educators are reluctant toward technology changes and view it as a burden. An emerging crisis factor among nursing colleges is the average age of faculty members being older than 51 years. The purpose of this study is to describe nurse faculty preferences about the use of technologies and to examine relationships between their preferences and years of experience.

YAP-IL-6ST autoregulatory loop activated on APC loss controls colonic tumorigenesis.

Loss of tumor suppressor adenomatous polyposis coli (APC) activates β-catenin to initiate colorectal tumorigenesis. However, β-catenin (CTNNB1) activating mutations rarely occur in human colorectal cancer (CRC). We found that APC loss also results in up-regulation of IL-6 signal transducer (IL-6ST/gp130), thereby activating Src family kinases (SFKs), YAP, and STAT3, which are simultaneously up-regulated in the majority of human CRC. Although, initial YAP activation, which stimulates IL6ST gene transcripti...

YAP/TAZ initiate and maintain Schwann cell myelination.

Nuclear exclusion of the transcriptional regulators and potent oncoproteins, YAP/TAZ, is considered necessary for adult tissue homeostasis. Here we show that nuclear YAP/TAZ are essential regulators of peripheral nerve development and maintenance. To proliferate, developing Schwann cells (SCs) require YAP/TAZ to enter S-phase and, without them, fail to generate sufficient SCs for timely axon sorting. To differentiate, SCs require YAP/TAZ to upregulate Krox20 and, without them, completely fail to myelinate, ...

YvqE and CovRS of Group A Streptococcus Play a Pivotal Role in Viability and Phenotypic Adaptations to Multiple Environmental Stresses.

Streptococcus pyogenes (group A Streptococcus, or GAS) is a human pathogen that causes a wide range of diseases. For successful colonization within a variety of host niches, GAS utilizes TCSs to sense and respond to environmental changes and adapts its pathogenic traits accordingly; however, many GAS TCSs and their interactions remain uncharacterized. Here, we elucidated the roles of a poorly characterized TCS, YvqEC, and a well-studied TCS, CovRS, in 2 different GAS strain SSI-1 and JRS4, respectively. Del...

Y-27632, a Rho-associated protein kinase inhibitor, inhibits systemic lupus erythematosus.

The purpose of the present study was to evaluate whether Rho-kinase inhibition (Y-27632) modulated the expressions of nuclear factor kappaB (NF-κB) in systemic lupus erythematosus. 20 wild type mice and 20 MRL/lpr mice were applied for the research. The animals were randomly assigned to wild type, wild type+Y-27632 group, MRL/lpr group and MRL/lpr+Y-27632 group. 5mg/kg Y-27632 was intravenously injected to inhibit the ROCK expressions.Y-27632 significantly decreased the serum levels of interleukin-6 (IL-6)...

YAMAT-seq: an efficient method for high-throughput sequencing of mature transfer RNAs.

Besides translation, transfer RNAs (tRNAs) play many non-canonical roles in various biological pathways and exhibit highly variable expression profiles. To unravel the emerging complexities of tRNA biology and molecular mechanisms underlying them, an efficient tRNA sequencing method is required. However, the rigid structure of tRNA has been presenting a challenge to the development of such methods. We report the development of Y-shaped Adapter-ligated MAture TRNA sequencing (YAMAT-seq), an efficient and con...

Yet another angle, but residues nonetheless: 26 years of EuroResidue Conferences!

Yersinia pestis acetyltransferase-mediated dual acetylation at the serine and lysine residues enhances the auto-ubiquitination of ubiquitin ligase MARCH8 in human cells.

Lysine acetylation is known as a post translational modification (PTM) by histone acetyltransferases (HAT) that modifies histones and non-histone proteins to regulate gene expression. Serine acetylation, however, is reported in mammalian hosts by serine acetyltransferase of Yersinia pestis (YopJ) during infection. The protein target and cellular function of bacterial YopJ in mammalian systems are not fully addressed. Here we report dual acetylation at the serine and lysine residues by transiently expressed ...

Yeast Short-Lived Actin-Associated Protein Forms a Metastable Prion in Response to Thermal Stress.

Self-perpetuating ordered protein aggregates (amyloids and prions) are associated with a variety of neurodegenerative disorders. Although environmental agents have been linked to certain amyloid diseases, the molecular basis of their action remains unclear. We have employed endogenous yeast prions as a model system to study environmental control of amyloid formation. A short-lived actin-associated yeast protein Lsb2 can trigger prion formation by other proteins in a mode regulated by the cytoskeleton and ub...
