The structures of neutral boron clusters, B(11), B(16), and B(17), have been investigated using vibrational spectroscopy and ab initio calculations. Infrared absorption spectra in the wavelength range of 650 to 1550 cm(-1) are obtained for the three neutral boron clusters from the enhancement of their near-threshold ionization efficiency at a fixed UV wavelength of 157 nm (7.87 eV) after resona...

depression, as a mental disorder, affects more than 300 million people of all ages every year. it is said to be associated with neuroinflammation. depression has affected women more than men. over the world, people are disabled due to depression rather than any other condition. neuroinflammation is the brain’s reaction to injury. apparently there is a link between neuroinflammation and depressi...

The chlorophyll-a (Chl-a) concentration of eutrophic lakes fluctuates significantly due to the disturbance wind and anthropogenic activities on water body. Consequently, estimation Chl-a has become an immense challenge. Due urgent demand rapid development in high-resolution earth observation systems, it crucial assess hyperspectral satellite imagery capabilities inland monitoring. Orbita (OHS) ...

Xanthomonas albilineans produces a family of polyketide-peptide compounds called albicidins which are highly potent antibiotics and phytotoxins as a result of their inhibition of prokaryotic DNA replication. Here we show that albicidin is a potent inhibitor of the supercoiling activity of bacterial and plant DNA gyrases, with 50% inhibitory concentrations (40 to 50 nM) less than those of most c...

We have studied the time sequence degradation of native insulin by insulin protease from human fibroblast using multiple steps involving purification of the products by high performance liquid chromatography, determination of peak composition by amino acid sequence analysis, and confirmation of structure by mass spectrometry and thus elucidated the sites of cleavage of insulin by human insulin ...

BACKGROUND Major depressive disorder (MDD) is a common mental disorder worldwide, but now there is a lack of clinically effective assessment and management of MDD. In this study, we used technetium-99 m ethylcysteinate dimer ([99mTc]ECD) SPECT/CT to characterize the regional cerebral blood flow (rCBF) status of MDD patients, and to explore an objective image assessment model of MDD which is non...

A series of genetically related lines of common bean (Phaseolus vulgaris L.) integrate a progressive deficiency in major storage proteins, the 7S globulin phaseolin and lectins. SARC1 integrates a lectin-like protein, arcelin-1 from a wild common bean accession. SMARC1N-PN1 is deficient in major lectins, including erythroagglutinating phytohemagglutinin (PHA-E) but not α-amylase inhibitor, and ...

To the Editor: 1 work at an overseas American institution, and there are extended delays in receipt of journals by our medical library. So, it was only a few days ago that I saw the article entitled “Weak Association between HLA-B27 and the Spondylarthropies in Lebanon,” which was published in the February 1997 issue of Arthritis & Rheumatism (1). I would like to draw the attention of the Leban...
