The title stannoxane is a toluene-solvated dimer, [Sn(4)(C(7)H(6)Cl)(8)Cl(2)O(2)(OH)(2)]·C(7)H(8), the tetra-nuclear mol-ecule lying across a center of inversion. The Sn(4)O(4) framework, whose two independent Sn atoms show trigonal bipyramidal coordination, is essentially planar (r.m.s deviation = 0.02 Å). One of the two chloro-benzyl groups of the chloridodiorganyltin unit is disordered over ...
Synthesis protocols for colloidal nanocrystals (NCs) with narrow size and shape distributions are of particular interest for the successful implementation of these nanocrystals into devices. Moreover, the preparation of NCs with well-defined crystal phases is of key importance. In this work, we show that Sn(IV)-thiolate complexes formed in situ strongly influence the nucleation and growth rates...
Human plasma platelet-activating factor (PAF) acetylhydrolase hydrolyzes the sn-2 acetyl residue of PAF, but not phospholipids with long chain sn-2 residues. It is associated with low density lipoprotein (LDL) particles, and is the LDL-associated phospholipase A, activity that specifically degrades oxidatively damaged phospholipids (Stremler, K. E., Stafforini, D. M., Prescott, S. M., Zimmerman...
In this work, new biodegradable ABCBA type pentablock copolymers with different mole ratio of L-lactide and PPDO-b-PEG-b-PPDO triblock copolymer were synthesized and characterized. In the first step, PPDO-b-PEG-b-PPDO triblock copolymer was synthesized via a ring-opening polymerization of P-DiOxanone (PDO) monomer with Poly (Ethylene Glycol) (P...
The study area is located in west of Iran (38 km SW of Qorveh). This region is part of Sanandaj-Sirjan zone. This area contains several pegmatitic dikes and based on mineralogical and geochemical characteristics belong to muscovite-rare-element pegmatites. The lithology of this body varies from pegmatitic syenogranite to granodiorite. Various rock bodies in this suite are mostly I-type and calc...
Statement of Problem: Anthropometry is applied in medical professions such as maxillofacial surgery,growth and development studies, plastic surgery, bioengineering and non- medical branches such as like shoe- making and eye- glasses industries.Aim: The aim of the present study was to determine facial and cranial ratios among Isfahan young adults.Materials and Methods: A study was done randomly ...
Since therapeutic peptides and oligonucleotides are gathering interests as active pharmaceutical ingredients (APIs), nanoparticulate drug delivery systems are becoming of great importance. Thereby, the possibility to design drug delivery systems according to the therapeutic needs of APIs enhances clinical implementation. Over the last years, the focus of our group was laid on protamine-oligonuc...
