antineutrophil cytoplasmic autoanibodies (anca) were detecte in patients with certain autoimmune vascular disease such as wegner’s granulomatosis, polyarthrits nodosa and systemic luuc erythematous. indirect immunofluorescence (iif) technique was employed to detec these autoantibodies.anca have been recently detected in some forms of inflammatory bowel disease (ibd), ulcerative colitis (u.c). c...

nowadays, using natural preservatives than synthetic ones is increasing. the present study was aimed to compare the effect of thyme (zataria multiflora boiss), onion (allium cepa) and ziziphora clinopodioides extracts on shelf-life extending of rainbow trout (oncorhynchus mykiss) salted, vacuum packaged fillet, kept at 4°c. for this purpose fish filets were kept in 4 treatment: salted in brine ...

Introduction: HER2/neu, a member of the epidermal growth factor receptor family, has been shown to be over-expressed in some tumors. The purpose of this study was to determine the salivary levels and tissue expression of HER2/neu in patients with head and neck squamous cell carcinoma (HNSCC) and their correlation with clinicopathologic parameters.   Materials and Methods: Enzyme-linked immu...

Exposure to solar ultraviolet B (UV-B) is a known causative factor for many skin complications such as wrinkles, black spots, shedding and inflammation. Within the wavelengths 280‑320 nm, UV-B can penetrate to the epidermal level. This investigation aimed to test whether extracts from the tropical abalone [Haliotis asinina (H. asinina)] mucus-secreting tissues, the hypobranchial gland (HBG) and...

The mechanical properties of cells change as they proceed through the cell cycle, primarily owing to regulation of actin and myosin II. Most models for cell mechanics focus on actomyosin in the cortex and ignore possible roles in bulk cytoplasm. We explored cell cycle regulation of bulk cytoplasmic actomyosin in Xenopus egg extracts, which is almost undiluted cytoplasm from unfertilized eggs. W...

We have used an in vivo system generating assayable amounts of a specific pre-mRNA to study the relationship between splicing and an operationally defined nuclear matrix preparation (NM). When NM is prepared by extraction of DNase I-treated nuclei with an approximately physiological concentration of KCl (0.1 M), a portion of NM-associated precursor can be spliced in vitro in the presence of ATP...

Pre-mRNA (precursor mRNA) enriched for globin-gene transcription products was prepared from murine erythroleukaemia cells induced to differentiate with dimethyl sulphoxide. The pre-mRNA was prepared from nuclear RNA by oligo(dT)-cellulose chromatography followed by sucrose-gradient centrifugation. The pre-mRNA thus obtained was utilized as the substrate for a splicing assay based on sequential ...

Problem statement: The goal of the current investigation was to clarify the effects of Citrullus colocynthis pulp extract on the structure of the liver of diabetic rats at both light and scanning electron microscopic levels. Approach: Forty-eight adult male albino rats were equally allocated into four groups: Group1: control, Group 2: Citrullus colocynthis-treated, Group 3: diabetic rats and Gr...
