A cytosol liver extract was prepared from adult dog livers and from liver remnants that had been regenerating for one, two and three days after 72 per cent partial hepatectomy. Given intraportally, the most active of these cytosols did not stimulate proliferation in the livers of normal dogs. However, infused during a six hour period into the portal vein of test group dogs, the cytosol from 48 ...

5S ribosomal RNA specifically inhibits transcription of cloned repeating units of 5S DNA in a nuclear extract of Xenopus oocytes. The inhibition can be explained by the interaction of 5S RNA with a transcription factor that binds specifically to a control region located within the 5S RNA gene. This transcription factor is identical to an abundant cytoplasmic protein that is known to be complexe...

Jackfruit leaves are one of the medical plants that have many benefits. In general, jackfruit known as animal feed, but behind their function health benefits because contain antimicrobials including flavonoids, tannins, saponins can dissolve in water and work to damage cytoplasmic membranes denature cell proteins bacteria. Staphylococcus aureus is a gram-positive bacterium arranged clusters (li...

In this study, zinc oxide nanostructures (ZnO NS) were synthesized using Pyrus pyrifolia fruit extract. Biophysical characterization results confirmed that the materials are crystalline wurtzite ZnO structures. Field emission scanning electron microscopy (FESEM) revealed NS cubical, and sizes range 20–80 nm. Transmission (TEM) XRD a crystal lattice spacing of 0.23 nm (101) plane on NS. UV-Visib...

background: oral squamous cell carcinoma is the sixth most common malignancy in the world today.  ing1b/p33 is a newly-discovered tumor suppressor which enhances p53 activity. transfer of p33 protein from nucleus to cytoplasmic compartment has been previously reported in leukemias. the objective of this study was to determine the correlation between p33ing1b cytoplasmic transfer and lymph node ...

Background: Metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. The aim of this study was to determine the relationship between the expression of stem cell marker CD166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.Methods: From 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in Babol...

Background: Inflammatory bowel disease unclassified (IBDU) is considered to be an aberrant immune response with loss of tolerance to many antigens. Objective: This paper tries to address whether there is any value to test for auto-antibodies in such patients. Methods: 60 patients with inflammatory bowel disease unclassified participated in the study. Auto-antibodies to nuclear antigen, intestin...

A system for studying the in vitro replication of the genome RNAs of Sendai virus and its defective interfering particle DI-H has been developed. Cytoplasmic extracts of baby hamster kidney cells infected with wild-type Sendai virus or coinfected with wild-type Sendai virus plus DI-H were prepared after lysolecithin treatment at 12 h postinfection. The extracts supported the transcription of si...

conclusions patients treated with ptu should be closely monitored and followed up, even if the drug has been used for several years. when patients develop progressive dyspnea with alveolar opacities on chest imaging that cannot be explained otherwise, alveolar hemorrhage should be an important differential diagnosis while investigating the case. early diagnosis and prompt discontinuation of the...

introduction antineutrophil cytoplasmic antibodies (anca)-associated glomerulonephritis (gn) is characterized by necrotizing and crescentic gn with paucity of immunoglobulin (ig) and complement deposition, which is also known as pauci-immune crescentic gn. membranous nephropathy (mn) is characterized by the formation of subepithelial immune deposit with resultant changes in glomerular basement ...
