In contrast to symmetric division in mitosis, mammalian oocyte maturation is characterized by asymmetric cell division that produces a large egg and a small polar body. The asymmetry results from oocyte polarization, which includes spindle positioning, migration, and cortical reorganization, and this process is critical for fertilization and the retention ...

Recent work has implicated members of the evolutionarily conserved family of coronin proteins - in particular coronin 1 - in immune homeostasis. Coronins are involved in processes as diverse as pathogen survival in phagocytes and homeostatic T cell signalling. Notably, in both mice and humans, coronin mutations are associated with ...

This paper presents a novel method for the self-assembly of aluminum nanoparticles on Si and fused silica. Due to high reactivity with oxygen, ex-vacuo annealing of thin deposited metal films, a method used extensively with other metals, does not work with aluminum. In the present experiment this problem was overcome ...

Only a few plasmid-borne AmpC (pAmpC) β-lactamases, such as CMY-2, can account for carbapenem resistance in Enterobacteriaceae in combination with outer membrane impermeability. The aim of this study was to elucidate the contribution of Asn-346, which is well-conserved among carbapenem-hydrolyzing pAmpCs, to the hydrolysis spectrum of CMY-2. Site-directed mutagenesis experiments ...

We describe the synthesis of self-assembling cyclic octapeptides of alternating d- and l-chirality conjugated to two poly(2-ethyl-2-oxazoline) chains. The resulting conjugates form nanotubes in water, which are reversibly transformed into microparticles as the temperature reaches the cloud point temperature of the conjugate.

Adult stem cells reside in hypoxic niches and embryonic stem cells (ESCs) are derived from a low oxygen environment. However, it is not clear whether hypoxia is critical for stem cell fate since for example human ESCs (hESCs) are able to self-renew in atmospheric oxygen concentrations as well. We now ...

About 10 % of infertile/subfertile women are diagnosed with diminished ovarian reserve (DOR), of which < 5 % will become pregnant spontaneously. Fragile X (FMR1) genetic testing may provide a reason for her early ovarian aging and/or have reproductive implications. Seven women with DOR (genetic study subset) and the male partners of six of ...

Glutathione S-transferase P1 (GSTP1) gene Ile105Val polymorphism has been suggested to be involved in the development of cancer. However, the results from the studies regarding the association between GSTP1 Ile105Val polymorphism and hepatocellular carcinoma risk have been inconsistent. Thus, we performed a meta-analysis to investigate the association. Published literature from ...

Human embryonic stem cells (hESCs) are maintained in a self-renewing state by an interconnected network of mechanisms that sustain pluripotency, promote proliferation and survival, and prevent differentiation. We sought to find novel genes that could contribute to one or more of these processes by using a gain-of-function screen of a ...

Simple tris(2-aminoethyl)amine (TREN) based tripodal urea receptors are investigated for the encapsulation of divalent oxalate (C2O4(2-)) in a semi-aqueous medium. A single crystal X-ray diffraction study shows that the receptor with 3-cyanophenyl functionality captures a staggered conformer whereas the 3-fluorophenyl functionalized receptor encapsulates a less stable planar conformer.

Posttranslational modification of tyrosine to 3,4-dihydroxyphenylalanine (dopa) yields a unique functional group in biomolecular systems. Oxidation produces a quinone, which can undergo cross linking while deprotonation is well suited to metal binding. Mussels, tunicates and bacteria chelate iron and other metals with multiple dopa subunits. Solution equilibria between catechols and ...

Abstract The fungus Amanita phalloides is known to contain two main groups of toxins: amanitins and phallotoxins. The amanitins group effectively blocks the RNA polymerase II enzyme found in eukaryotic cells. As alpha amanitin has a lethal effect on the majority of eukaryotic cells, it can be valuable as an ...

OBJECTIVES: The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in cystic fibrosis (CF) patients in the United States is approximately 25%. Little is known about the relative proportion of hospital- versus community-associated strains or the antimicrobial susceptibility of MRSA in different CF centers. We hypothesized that the majority of MRSA isolates ...

We previously reported that treatment of B16 melanotic melanoma cells with reduced glutathione (GSH) converts them to amelanotic cells without any significant down-regulation of tyrosinase activity. To characterize the cellular mechanism(s) involved, we determined the intracellular distribution of melanocyte-specific proteins, especially in melanin synthesis-specific organelles, termed melanosomes by subcellular fractionation ...

BACKGROUND AND PURPOSE: Nitric oxide (NO) is known to activate NO-sensitive guanylyl cyclase (NO-GC) and to elicit cGMP production. However, NO has also been proposed to induce cGMP-independent effects. It is accepted practice to use specific NO-GC inhibitors, such as ODQ or NS2028, to assess cGMP-dependent NO effects. Consequently, NO-induced ...

The perinatal environment influences stress responses in the long-term, as does body composition. Male rats suckled in large litters, where they have reduced access to milk and attention from the dam, are less anxious and have attenuated hypothalamic-pituitary-adrenal (HPA) axis responses to stress than those from control litters. Here we ...

In Saccharomyces cerevisiae, synthesis of trehalose-6-phosphate (T6P) is essential for growth on most fermentable carbon sources. The metabolic response to glucose was analysed in mutants with different capacity to accumulate T6P. A mutant carrying a deletion in the T6P synthase encoding gene, TPS1, which had no measurable T6P exhibited impaired ...
