Reaction of K[HC(C(Me)NAr')(2)] (Ar' = 2,6-C(6)H(3)(i)Pr(2)) with Mg(BH(4))(2) afforded the pseudo four-coordinate tetrahydroborate complex Mg{HC(C(Me)NAr')(2)}(BH(4))(THF) (1). The corresponding reaction of Ca(BH(4))(2)(THF)(2) or Sr(BH(4))(2)(THF)(2) gave the pseudo five-coordinate analogues M{HC(C(Me)NAr')(2)}(BH(4))(THF)(2) (M = Ca (2) or Sr (3)). All three compounds 1-3 have been structura...

The subject of this review is the impact of long-term changes in temperature on plant growth and its underlying components. The discussion highlights the extent to which thermal acclimation of metabolism is intrinsically linked to the plasticity of a range of biochemical and morphological traits. The fact that there is often a trade-off between temperature-mediated changes in net assimilation r...

Three main types of inflammatory Non-Allergic Rhinitis (NAR) have been defined: NAR infiltrated by eosinophils (NARES), by mast cells (NARMA), and by neutrophils (NARNE). A new particular type has been characterized with current infiltration by eosinophils and mast cells (NARESMA). The aim of this study is to evaluate the clinical and functional characteristics in patients with NARES, NARMA, NA...

Individuals with seasonal allergic rhinitis (SAR) show a more marked nasal obstructive response (increases in nasal airways resistance or NAR) after provocation with chlorine gas (Cl2) than do nonrhinitic (NR) controls. We were interested in learning whether similar differential responsiveness was apparent after provocation with acetic acid vapor. Sixteen nonsmoking, nonasthmatic subjects, aged...

BACKGROUND The objective of this study was to evaluate the influence of the environmental factors (meteorological factors, air pollutant levels, etc.) on the number of clinic consultations for nonallergic rhinitis (NAR). METHODS Among the 9056 outpatients visiting a general internal medicine clinic in Japan between August 2012 and the end of July 2013 (counting return visitors as multiple cas...

Axonal and nerve terminal action potentials often display a depolarizing after potential (DAP). However, the underlying mechanism that generates the DAP, and its impact on firing patterns, are poorly understood at axon terminals. Here, we find that at calyx of Held nerve terminals in the rat auditory brainstem the DAP is blocked by low doses of externally applied TTX or by the internal dialysis...

There is little information about specific changes in submucosal gland exocytosis in diseases such as allergic rhinitis (AR), nonallergic rhinitis (NAR), and cystic fibrosis (CF). Nasal lavage fluids were collected from normal, AR, NAR, and CF subjects. Concentrations of lysozyme, Alcian blue-staining mucoglycoconjugate material (AB+m), and human high-molecular-weight mucoglycoconjugates recogn...

In four experiments, the effects of pre-thaw delay, method of thawing, temperature of thawing solution and pellet volume on acrosome morphology and moti l i ty of" boar spermatozoa frozen by the pellet method were examined. Holding the frozen pellets for 0, 1.5, 3 or 4.5 min in a Styrofoam container before transferring them into the thawing solution resulted in maximum post-thaw percentages of ...

The 2018 Nucleic Acids Research Database Issue contains 181 papers spanning molecular biology. Among them, 82 are new and 84 are updates describing resources that appeared in the Issue previously. The remaining 15 cover databases most recently published elsewhere. Databases in the area of nucleic acids include 3DIV for visualisation of data on genome 3D structure and RNArchitecture, a hierarchi...

Mechanical strain plays a key role in the physics and operation of nanoscale semiconductor systems, including quantum dots single-dopant devices. Here, we describe design nanoelectronic device, where single nuclear spin is coherently controlled via acoustic resonance (NAR) through local application dynamical strain. The drives transitions by modulating quadrupole interaction. We adopt an AlN pi...
