Ribonucleoprotein fragments are isolated by mild ribonuclease digestion of E. coli 30S ribosomal subunits, and are deproteinized and subjected to a second partial digestion. Base-pairing between the resulting small RNA fragments is investigated using the two-dimensional gel electrophoresis procedure already reported (see Ref. 1). The interactions thus found are incorporated into a secondary str...

Currently, there is significant demand for pillows with improved pressure-relief features made from natural materials, alternatives to petrochemical-based foams. To meet the requirements, this study’s approach develop latex foam deproteinized rubber (DPNR) a unique dual-density cervical-shaped structure. In work, DPNR were produced at three different density levels which are high-density, mediu...

conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...

statement of problem: reconstruction methods are an essential prerequisite for functional rehabilitation of the stomatognathic system. platelet-rich plasma (prp) offers a new and potentially useful adjunct to bone substitute materials (e.g. xenografts) in oral and maxillofacial bone and implant reconstructive surgery. purpose: an animal study was carried out to investigate the influence of prp ...

In this study, the chitin and chitosan were extracted from shrimp shell through two-steps acid alkaline treatment. The was deproteinized by 1 M of sodium hydroxide demineralised 1%, 2%, 3%, 4% 5% hydrochloric acid, respectively. produced characterized FTIR FESEM. depicted that in α-chitin isomorph. surface morphology found to increase with an concentration. film rod-like micro-structure when di...

Abstract Soybean hulls (SBHs) are one of the main by-products soybean crushing, usually destined for animal feeding or to become a putrescible waste. In this work, we upgraded SBHs materials with antimicrobial properties. After extraction peroxidase from SBHs, an enzyme applicable in different technological sectors and naturally present hulls, exhausted biomass was subjected acid–base treatment...

determined the amino acid nitrogen content of deproteinized blood from advanced leukemia cases. They found that the amino acid nitrogeni imscreased or decreased in a fairly consistentmanner accoi-ding to the msunsber of white blood cells present-. \Talues for the non-protein nitrogen levels in the blood plasma of patients with acute, chronic lymphatic and chromsie granulocytie leukemia have Sit...

Deproteinized natural rubber/graphene oxide (DPNR/GO) nanocomposite was prepared and characterized in the present work. GO synthesized by oxidation process via Hummer modified method, it with X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, nuclear magnetic resonance (NMR), water contact angle. The presence of hydrophilic functional groups sheet confirmed FT-IR, NMR cha...
