Gamma-aminobutyric acid (GABA) is a non-protein amino acid commonly present in all organisms. Because cellular levels of GABA in plants are mainly regulated by synthesis (glutamate decarboxylase, GAD) and catabolism (GABA-transaminase, GABA-T), we attempted seed-specific manipulation of the GABA shunt to achieve stable GABA accumulation in rice. A truncated GAD2 ...

Copolymer chains consisting of acrylamide units and guanine (G)-containing oligonucleotide-tethered acrylamide units undergo in the presence of K(+) ions, crosslinking by G-quadruplexes to yield a hydrogel. The hydrogel is dissociated upon addition of 18-crown-6 ether that traps the K(+) ions. Reversible formation and dissociation of the hydrogel is demonstrated by ...

Damage to one vestibular labyrinth or nerve causes a central tone imbalance, reflected by prominent spontaneous nystagmus. Central adaptive mechanisms eliminate the nystagmus over several days, and the mechanisms underlying this process have received extensive study. The characteristics of vestibular compensation when the tone imbalance is presented gradually or repeatedly ...

AIMS: Ubiquilin-1 acts as an adaptor protein that mediates the translocation of polyubiquitinated proteins to the proteasome for degradation. Although previous studies suggested a key role of ubiquilin-1 in the pathogenesis of Alzheimer's disease (AD), a direct relationship between ubiquilin-1 and Hirano bodies in AD brains remains unknown. METHODS: By ...

Recent gene expression data suggest that the region on which the onychophoran antenna is situated corresponds to the anteriormost, apparently appendage-less region of the arthropod head. The fate of the onychophoran antenna (or any appendage-like precursor), also called the primary antenna, has been discussed intensively, and there are conflicting suggestions ...

The TRAMP (Transgenic Adenocarcinoma of the Mouse Prostate) and LADY (Probasin-large T antigen transgenic mouse) mice are widely used autochthonous models of prostate cancer. Both models utilise probasin promoters to direct androgen-regulated expression of oncogenic SV40 specifically to epithelial cells of the mouse prostate. The oncogenic processes and phenotypes which ...

Soil salinity restricts plant growth and productivity. Na(+) represents the major ion causing toxicity because it competes with K(+) for binding sites at the plasma membrane. Inoculation with arbuscular mycorrhizal fungi (AMF) can alleviate salt stress in the host plant through several mechanisms. These may include ion selection during the ...

Cysteine-conjugated volatile thiols are powerful aromatic compounds that contribute to the fruity notes of many white wines and especially Sauvignon Blanc. Genetic selection programs of wine yeast starters able to produce more volatile thiols constitute, therefore, an important goal for the wine industry. Recent investigations on yeast metabolism suggested that ...

Alcohol use can cause significant harm. We examined the relationships between neighborhood disadvantage, consumption of high-alcohol-content beverages (HACB), drinking norms, and self-reported drinking consequences using data from the 2000 and 2005 National Alcohol Surveys (N = 9,971 current drinkers) and the 2000 Decennial Census. We hypothesized that (1) individuals living in disadvantaged ...

Human disturbances to ecosystems have created challenges to populations worldwide, forcing them to respond phenotypically in ways that increase their fitness under current conditions. One approach to examining population responses to disturbance in species with complex life histories is to study species that exhibit spatial patterns in their phenotypic response ...

Empirical studies and conceptual frameworks presented in the extant literature offer a static imagining of academic failure. Time-to-event analysis, which captures the dynamism of individual factors, as when they determine the failure to properly tailor timely strategies, impose longitudinal studies which are still lacking within the field. The aims of ...

Reference region (RR) approaches (RRAs) for positron emission tomography (PET) brain studies aim to obtain full quantification without arterial input function (IF) sampling, an invasive and costly procedure. Although they need a reliable RR and are only able to estimate the nondisplaceable binding potential (BP(ND)), RRAs are widely used. If ...

We develop an information-theoretic method for gene-gene (GGI) and gene-environmental interactions (GEI) analysis of syndromes, defined as a phenotype vector comprising multiple quantitative traits (QTs). The K-way interaction information (KWII), an information-theoretic metric, was derived for multivariate normal distributed phenotype vectors. The utility of the method was challenged with three ...

Untreated acromegaly is associated with a twofold to fourfold increased mortality risk compared to the population. Recently, new therapeutic modalities have been developed and may contribute to an improvement in treatment outcomes in patients with acromegaly. In the current study we determined the clinical features and recent therapeutic outcomes in ...

Zinc isotope abundances are fairly constant in igneous rocks and shales and are left unfractionated by hydrothermal processes at pH < 5.5. For that reason, Zn isotopes in sediments can be used to trace the changing chemistry of the hydrosphere. Here, we report Zn isotope compositions in Fe oxides from banded iron ...

Peripheral blood mononuclear cells (PBMC) have a great potential for nutrition and obesity studies. PBMC reflect the nutritional response of key organs involved in energy homeostasis maintenance, which is altered in the obese state. Here, we aimed to determine the usefulness of PBMC as a source of early markers of ...

Gestures are common when people convey spatial information, for example, when they give directions or describe motion in space. Here, we examine the gestures speakers produce when they explain how they solved mental rotation problems (Shepard and Meltzer in Science 171:701-703, 1971). We asked whether speakers gesture differently while describing ...

BACKGROUND: Segmental dose reduction with increasing age after thoracic epidural anaesthesia (TEA) has been documented. We hypothesised that after a fixed loading dose of ropivacaine at the T3-T4 level, increasing age would result in more extended analgesic spread. In addition, other aspects of neural blockade and haemodynamic changes were studied. ...

A Gram-staining-negative, non-spore-forming, aerobic, non-flagellated, non-gliding and rod-shaped bacterial strain, designated M-M3(T), was isolated from marine sand on the southern coast of South Korea and subjected to a polyphasic study. Strain M-M3(T) was observed to grow optimally at 25-30 °C, at pH 7.0-8.0 and in the presence of 2 % (w/v) NaCl. ...

There is strong evidence that a restricted part of the chick forebrain, the intermediate medial mesopallium (IMM), stores information acquired through the learning process of visual imprinting. We have previously demonstrated that at 1 h but not 24 h after imprinting training, a learning-specific increase in the amount of membrane Thr286-autophosphorylated α-calcium/calmodulin-dependent ...
