Mass selective deposition of C7H3(+) (m/z = 87) into solid neon reveals the 1(1)A1←X(1)A1 electronic absorption system of hepta-1,2,3,4,5,6-heptahexaenylium cation B(+) [H2CCCCCCCH](+) with an origin band at 441.3 nm, 1(1)A'←X(1)A' transition of 2,4-pentadiynylium,1-ethynyl cation C(+) [HCCCHCCCCH](+) starting at 414.6 nm and the 1(1)A1←X(1)A1 one of cyclopropenylium,1,3-butadiynyl cation A(+) ...
Introduction Roughly 30 peer reviewed papers have been published on B1+ mapping in the last 2 years from 2010 to 2011. This shows the vitality of a research area that has started back in the 80’s [1, 2]. The RF field behavior in biological tissue and its spatial variations was assessed very early [3]. The transmit RF field can be described by a time independent, spatially varying B1+ map times ...
Several recent studies reported that Krüppel-like factor (KLF)2 controls trafficking, development, and function of B cells. Conditional B cell KLF2 knockout mice have increased numbers of marginal zone B cells and decreased numbers of B1 phenoytpe cells. However, it was unclear whether KLF2 is required for B1 B cell development, survival, or phenotypic maintenance. We show that B1 phenotype B c...
PURPOSE Cyclin B1 plays an important role as a mitotic cyclin in the G(2)-M phase transition during the cell cycle. The aim of the present study was to elucidate the biological significance of cyclin B1 expression in squamous cell carcinoma (SCC) of the esophagus. EXPERIMENTAL DESIGN We analyzed immunohistochemically the expression of cyclin B1 in the tumor specimens from 120 patients with SC...
تأثیر پروتکسین در کاهش تأثیرات منفی تغذیة جیرههای حاوی آفلاتوکسین B1 بر عملکرد، پاسخ ایمنی، کیفیت گوشت و فلور میکروبی ایلئوم با استفاده از 320 قطعه بلدرچین ژاپنی هفتروزه در قالب طرح کاملاً تصادفی با چهار تیمار (جیرة شاهد (بدون افزودنی)، جیرة حاوی 5/2 میلیگرم در کیلوگرم آفلاتوکسین B1، جیرة حاوی 150 میلیگرم در کیلوگرم پروتکسین، جیرة حاوی 5/2 میلیگرم آفلاتوکسین B1+150 میلیگرم در کیلوگرم پروت...
We report that a fatty acyl transferase, endophilin B1, is required for maintenance of mitochondrial morphology. Down-regulation of this protein or overexpression of endophilin B1 lacking the NH(2)-terminal lipid-modifying domain causes striking alterations of the mitochondrial distribution and morphology. Dissociation of the outer mitochondrial membrane compartment from that of the matrix, and...
Global solvability of the problem (1),(2) was studied rather thoroughly (see, e.g., [1– 9] and the literature quoted therein). In the present paper new sufficient conditions of existence and nonexistence of so called blow-up solutions to the problem (1),(2) are given. To formulate the main results, we need to introduce the following notation and definitions. z = (zi) n i=1 ∈ R n is a vector wit...
We confirmed multiple picoeukaryotic algae, Ostreococcus, Micromonas, and Pelagomonas spp., as thiamine (vitamin B1) auxotrophs in laboratory experiments with axenic cultures. Examined strains have half saturation growth constants (Ks) for B1 between 1.26 and 6.22 pmol B1 L , which is higher than reported seawater concentrations. Minimum B1 cell quotas for Ostreococcus and Micromonas spp. are h...
Purpose: This study aimed to understand the prognostic value of integrin b1 expression in head andneck squamous cell carcinoma (HNSCC) and themechanismunderlying its associationwithmetastatic HNSCC. Experimental Design: Archival HNSCC tissues including 99 nonmetastatic primary tumors and 101 metastatic primary tumors were examined for the association of integrin b1 expression with metastasis an...
