Humic acid (HA) is a material that could be used to decrease erosion and improve soil structure. It also known biological crusts (biocrusts) have major role in stabilization, but the mechanism not well understood presence of HA, especially with mechanistic detachment rate parameters (b0 b1) Wilson model, where b0 dimensional parameter b1 threshold parameter. Therefore, this study intends (1) in...

The caecal chyme of pigs was incubated anaerobically in McDougall buffer with and without fumonisin B1 (5 μg/ml) for 0, 24 and 48 h. The plate count agar technique was applied for enumerating the amount of bacteria including aerobic, anaerobic bacteria, coliform, Escherichia coli and Lactobacillus sp. The quantitative polymerase chain reaction was also performed to estimate the number of copies...

Two glutathione S-transferase (GST) isozymes, A1/A1 and B1/B2, were purified from etiolated, O-1,3-dioxolan-2-yl-methyl-2,2,2, -trifluoro-4'-chloroacetophenone-oxime-treated sorghum (Sorghum bicolor L. Moench) shoots. GST A1/A1, a constitutively expressed homodimer, had a subunit molecular mass of 26 kD and an isoelectric point of 4.9. GST A1/A1 exhibited high activity with 1-chloro-2, 4, dinit...

Selective transporters account for rapid urea transport across plasma membranes of several cell types. UT-B1 urea transporter is widely distributed in rat and human tissues. Because mice exhibit high urea turnover and are the preferred species for gene engineering, we have delineated UT-B1 tissue expression in murine tissues. A cDNA was cloned from BALB/c mouse kidney, encoding a polypeptide th...

The cellular and molecular mechanisms governing bradykinin B1 and B2 receptor expression and function are poorly understood. We investigated the regulation of both B1 and B2 receptors in human embryonic lung fibroblasts (HEL 299) by the proinflammatory cytokines tumor necrosis factor alpha (TNF-alpha) and interleukin 1beta (IL-1beta). TNF-alpha and IL-1beta both induced a rapid and transient in...

Introduction: It has been shown that the B1 inhomogeneities in high field systems (e.g.7T) can severely compromise image quality. B1 inhomogeneities are still significant at 3T, but generally do not destroy the ability to image. However, the variations in flip angle (and hence contrast) across the field of excitation can still cause significant problems, particularly with applications where abs...

A human B-cell lymphoma xenograft model was used to test whether the administration of unlabeled MoAb prior to injection of radiolabeled monoclonal antibody (MoAb) improves delivery of the radiolabeled MoAb to tumor prior to testing in clinical radioimmunotherapy trials. The anti-B1/CD20 pan-B-cell MoAb reactive with human B-cell lymphomas and leukemias but not reactive with mouse B-cells was u...
