SEM images show ablation and etching of the surface. The well defined scaly contour is not seen and there are deep striations on the surface of samples treated in nitrogen atmosphere. In
case of samples exposed in O(2) atmosphere, micropores can be seen on the surface. Samples treated in nitrogen atmosphere for 15 min show nearly 100% exhaustion of acid dye as compared to 73% for untreated samples after 20 min of dyeing. Treated wool shows increased saturation dye uptake as well as improved rate of dyeing. Since these changes are restricted to surface and do not affect the bulk properties, these findings can have a significant effect on the commercial dyeing and finishing procedures used for wool and can be used to design cleaner and more efficient processes in future.

“Objective. INCB018424 inhibitor The purpose of this research was to provide further evidence to demonstrate the precision and accuracy of maxillofacial linear and angular measurements obtained by cone-beam computed tomography (CBCT) images.
Study design. The study population consisted of 15 dry human
skulls that were submitted to CBCT, and 3-dimensional (3D) images were generated. Linear and angular measurements based on conventional craniometric anatomical landmarks, and were identified in 3D-CBCT images by 2 radiologists twice each independently. Subsequently, physical measurements were made by a third examiner using a digital caliper and a digital goniometer.
Results. The results demonstrated no statistically significant Selleck AS1842856 difference between inter-and intra-examiner Wnt inhibitor analysis. Regarding accuracy test, no statistically significant differences were found of the comparison between the physical and CBCT-based linear and angular measurements for both examiners (P = .968 and .915, P = .844 and .700, respectively).
Conclusions.
3D-CBCT images can be used to obtain dimensionally accurate linear and angular measurements from bony maxillofacial structures and landmarks. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 108: 430-436)”
“Background: Plasmodium vivax is divided into two subtypes, a dominant form, VK210 and a variant form, VK247. This division is dependent on the amino acid composition of the circumsporozoite (CS) protein. In this study, the prevalence of the VK247 variant form of P. vivax was investigated in Myanmar.
Methods: The existence of malaria parasites in blood samples was determined by microscopic examination, polymerase chain reaction (PCR) and DNA hybridization assays. To test for antibodies against P. vivax and Plasmodium falciparum in blood samples, an indirect immunofluorescence antibody test (IFAT) was performed using asexual blood antigens. An enzyme-linked immunosorbent assay with synthetic VK210 and VK247 antigens was carried out to discriminate between the P. vivax subtypes.
