An extensive analysis of the conformational space of tryptophan (Trp) was performed at the B3LYP/6-311++G(d,p) level and verified by comparison with the infrared spectra of the compound isolated in low-temperature argon and xenon matrixes. Different types of conformers have been unequivocally identified in the matrixes. Type I exhibits the trans arrangement of the carboxylic group and is stabil...
Glycoprotein Ib Is Homogeneously Distributed on External and Internal Membranes of Resting Platelets
This position paper addresses the long-standing criticism that the International Baccalaureate (IB) is too closely associated with Western values and, despite its title, does not enable students to see the world from a truly international perspective. Considering evidence from different authorities, it analyses the IB learner profile and asks how appropriate it is for the cultures of East Asia....
In recent years, the production and consumption of thermally modified wood (TMW) has been increasing. Offcuts other waste generated during TMWs processing into products, as well already disposed products based on can be an input recycled raw material for particleboards (PBs). a laboratory, 16 mm thick 3-layer PBs bonded with urea-formaldehyde (UF) resin were produced at 5.8 MPa, 240 °C 8 s pres...
Fire-retardant (FR) treated wood-based panels, used commonly in furniture and construction, need to meet stringent fire safety regulations. This study presents a novel treatment for imparting resistance wood composites by applying separate solutions of phytic acid sodium silicate onto particles before the hot pressing at 160 °C. A scanning electron microscopy-energy dispersive X-ray spectroscop...
علیرغم پیشرفتهای قابل توجه در زمینه ایجاد باند مناسب مواد ترمیمی همرنگ با نسج دندان ، بقای باند ایجاد شده از مسائل چالش برانگیز است. به نظر می رسد استفاده از عوامل ایجادکننده کراس لینک (مانند اسید تانیک و کلرهگزیدین) می تواند به حفظ و افزایش استحکام باند رزین- عاج کمک نماید. هدف از انجام این مطالعه،مقایسه اسیدتانیک و کلرهگزیدین بر استحکام باند برشی سیستم های ادهزیو etch&rinse و self etch در عا...
The effects of two mineral adducts (dolomite and olivine) as proportion in Calabrian pine wood chip based-experimental panels which bonded with synthetic adhesive (UF) were evaluated. It appears both minerals (P: calabrian chip-, X: Dolomite- Y: Olivine composite proportions) improve the water repellent efficiency (WRE) properties at certain extent. In all experimental procedure, WRE increased ...
Force-dependent binding of platelet glycoprotein Ib (GPIb) receptors to plasma von Willebrand factor (VWF) plays a key role in hemostasis and thrombosis. Previous studies have suggested that VWF activation requires force-induced exposure of the GPIb binding site in the A1 domain that is autoinhibited by the neighboring A2 domain. However, the biochemical basis of this "mechanopresentation" rema...
The present clinical study aimed to assess the postoperative sensitivity (POS) after 48 hours and seven days in occlusal restorations bonded with three different adhesive systems, two of them containing glutaraldehyde. The restorative procedures were performed using the three-step etch-and-rinse Adper SBMP-Plus adhesive (SBMP), the two-step etch-and-rinse Gluma Comfort One Bond + Desensitizer a...
Previous studies have shown a decreased binding of monoclonal antibodies (MoAbs) to glycoprotein (GP) Ib-IX complexes on thrombin-stimulated platelets, but the reason for this is poorly understood. We have used (1) immunofluorescence procedures and flow cytometry, and (2) immunogold staining and electron microscopy to investigate this phenomenon. Washed platelets were incubated with alpha-throm...
