Pantothenic acid, a portion of the coenzyme A molecule (l), must be supplied in the diet for normal acetylation of p-aminobenzoic acid (PAB) (2) and of sulfanilamide (3) by the rat. Only at certain test levels of PAB, however, is pantothenate deficiency reflected by decreased acetylation (4). The present communication extends the study of the relation between acetylation and size of dose over a...

Antigenic variation among 13 Quebec isolates of bovine viral diarrhea virus (BVDV), 4 reference strains and 2 American isolates were studied by peroxidase-linked antibody assay (PLA assay) and neutralization test (NT). The Quebec strains consisted of 3 isolates before 1993 and 10 isolates from 1993. In the PLA assay, we compared 2 different fixatives, acetone and formalin. Acetone-fixation allo...

Ilex spinigera (Aquifoliaceae) plant is an evergreen tree or shrub with thick glossy dark green leaves and red fruits. This plant has medicinal properties and has been used traditionally in northern Iran for malaria treatment. The aim of this work is to evaluate the antioxidative activities and the inhibitory effect of I.spinigera on the oxidation of DNA. We have found no reports about the popu...

introduction: the molecular mechanisms involved in pathogenesis of esophageal cancer have been the main concern of several studies. in this study, we aimed to investigate the changes of serum prooxidant-antioxidant balance (pab) value as a redox index, as well as serum c-reactive protein (crp) compared to healthy control group. materials and methods: in a cross-sectional study, blood samples we...

ObjectivesComplete atrioventricular septal defect (cAVSD) repair is usually performed between 3 and 6 months of age. However, some children present with early heart failure requiring intervention. It unclear whether primary complete or initial pulmonary artery banding (PAB) provides better outcomes.MethodsAll patients (n = 194) who underwent surgery for cAVSD younger than age 1990 2019 were inc...

The present study aimed to develop polyethylene glycol–liquid crystals (PEG-LC) ointment formulations, assess their formulation characteristics, and establish biocompatibility impact on transdermal drug administration. PEG-LC formulations were prepared using a hydrophilic molecule, p-aminobenzoic acid (PAB). Formulation characterizations such as small-angle X-ray scattering, viscosity, pH, zeta...

While numerous researchers have investigated group behavior of robots which are each controlled in a behavior-based manner, none have yet thoroughly investigated the possibilities of extending the port-arbitrated behavior (PAB) paradigm across networks of robots. We present an extension to the well-de ned PAB techniques of behavioral interaction which provides standard abstractions for nessagin...

Xanthomonas oryzae pv. oryzicola (Xoc) causes bacterial leaf streak (BLS) in rice, a serious bacterial disease of rice in Asia and parts of Africa. The virulence mechanisms of Xoc are not entirely clear and control measures for BLS are poorly developed. The solo LuxR proteins are widespread and shown to be involved in virulence in some plant associated bacteria (PAB). Here, we have cloned and c...

Formation of a dense microtubule network that impedes cardiac contraction and intracellular transport occurs in severe pressure overload hypertrophy. This process is highly dynamic, since microtubule depolymerization causes striking improvement in contractile function. A molecular etiology for this cytoskeletal alteration has been defined in terms of type 1 and type 2A phosphatase-dependent sit...

The effect of steady-state increases in abdominal pressure (Pab) on cardiac performance was studied in seven acutely instrumented swine with pneumoperitoneum (PP). The animal was placed on volume-preset ventilation, and PP was created by air insufflation. Cardiac output (CO), right atrial (Pra), left atrial (Pla), pericardial (Ppe), and abdominal inferior vena cava pressures (Pivc) were measure...
