in this study one lymph node from cow with viral lymphosarcoma and one lymph node from healthy cow were analyzed by three different methods for protein extraction, include simple homogenizing in pbs, sonication and phenol extraction. tumor antigen detection relies on immunoprecipitation followed by sds-page. in this experiment streptococcus pyogenes was used for purification of immune complexes...

the dna molecule has been known to be the cellular target for many cytotoxic anticancer agents for several decades. understanding how drug molecules interact with dna has become an active research area in the interface between chemistry, molecular biology and medicine. dna extraction has been suggested as a main step affecting molecular dna technology such as pcr and pcr-based methods. therefor...

Orthodontic treatment for malocclusion correction may involve extraction or non-extraction of specified teeth for esthetic and functional harmony. Antero-posterior and transverse arch dimensional changes following orthodontic treatment has been evaluated using many methods. The present study evaluated the arch dimensional changes after orthodontic treatment in extraction and non-extraction case...

mandibular incisor extraction in carefully selected cases as an alternative option to four bicuspid extraction or non extraction treatment has been advocated. the purpose of this study was to determine the degree of improvement in occlusion in patients with bolton discrepancy treated by one lower incisor extraction using peer assessment rating index (par indexes).pre and post treatment dental c...

Lymphomas are solid malignant tumors having a wide spectrum of clinical and pathological features. Non-Hodgkin’s lymphoma (NHL) is a subtype of lymphoma with two-thirds of the cases presenting as lymph node enlargement. The remaining one third of NHL cases has been reported in the extranodal sites, including the gastro intestinal tract, Waldeyer’s ring, bone, skin, and brain. Intraoral non-Hodg...
