We studied the interaction of human neutrophils with nylon wool in vitro and during filtration Ieukapheresis (FL) to better understand cellular events detrimental to neutrophils that occur during FL. When neutrophils purified from blood by gradient centrifugation and sedimentation were incubated with nylon wool in vitro, release of lysozyme from the cells occurred rapidly and to a degree that w...

background: regardless of numerous advances in surgical techniques, selection of the best technique to sew up wounds and the best suture material are still controversial. several postoperative complications, including wound infection, stitched wound, chronic incision pain, wound dehiscence and hernia stitches result from many factors such as used suture material. objectives: the aim of the pres...

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

Mutagenesis in Escherichia coli, a subject of many years of study is considered to be related to DNA replication. DNA lesions nonrepaired by the error-free nucleotide excision repair (NER), base excision repair (BER) and recombination repair (RR), stop replication at the fork. Reinitiation needs translesion synthesis (TLS) by DNA polymerase V (UmuC), which in the presence of accessory proteins,...

Aim of the Study: This study aims to evaluate cytotoxicity different stereolithographic 3D printed materials and polyetheretherketone for varying time intervals using MTT assay by application these intra-oral usage. Materials Methods: Three groups disc specimens (5 mm diameter, 2 thick) were manufactured either selective laser melting (PA6 nylon, fiber reinforced PA6 nylon) or milling (PEEK). T...

Background: Non-absorbable materials (nylon) are always used in cinch sutures to maintain nasal width and improve harmonious facial symmetry orthognathic surgery. However, a few drawbacks of nylon have been clinically reported following surgery, such as irritation exposure the sutures. An absorbable material (PDS) has proposed sutures, not only avoid complications but also stabilize for long-te...

Three groups of patients who had undergone cataract extraction through a corneal incision closed with 10/0 nylon sutures one, two, and three years previously were recalled to determine the incidence of suture related complications. Broken corneal sutures were found in 87.5% of patients after two years and 90% after three years and were causing symptoms in over half the patients. It is recommend...

Titers of wild-type and recombinant adeno-associated viruses are routinely determined by DNA slot blot analysis. The binding of viral DNA to nylon membranes was found to be inhibited by magnesium ions, which are critical components of the DNase I digestion carried out prior to slot blot analysis. Mg2+ions also interfered with the adsorption of plasmid DNA to nylon and nitrocellulose membranes. ...

Immunocompetent cells were isolated from spleen of B. himalayanus and studied surface morphology of the three different cell types--(i) plastic adherent; (ii) nylon wool adherent; and (iii) nylon wool non-adherent cells. As revealed by scanning electron microscopy, they resembled the macrophages, B and T cells, respectively. Presence of such cell types indicated that Bufo himalayanus possessed ...

Some exploratory work on creep and inverse creep in nylon 6 monofilament, polyester multifilament yarn and wool and cotton spun yarns has been presented. It is observed that the extent of creep and inverse creep differs from material to material and depends on the initial stress. Cotton shows minimum inverse creep while nylon shows maximum inverse creep. Wool and polyester have intermediate inv...
