The crystal structure of the title compound, [Co(3)(C(5)H(9)O(2))(6)O(CH(4)O)(3)]Cl, consists of trinuclear Co(III) complex cations and chloride anions. The Co(III) cation has site symmetry m, and is coordinated by four oxygen atoms from four bridging pivalate groups, one central O anion and a methanol oxygen atom, forming a distorted octa-hedral geometry. The coordinated methanol mol-ecule is ...
The present study aimed to compare the results of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy (CL) at a single institution in Japan. Of the 212 patients with stage I/II/III colorectal cancer who received a curative resection, 98 patients underwent HALS and 114 patients underwent CL. The clinical background and post-operative management did not differ between the two gr...
چکیده سابقه و هدف:با توجه به شیوع اسکلتال اپن بایت و تناقض در مورد ارتباط میان ابعاد فضای حلقی وساختارهای کرانیوفاسیال. دراین مطالعه ، ابعاد فضای حلقی در دو گروه دارای اپن بایت اسکلتال وبدون اپن بایت اسکلتال در بیماران CLII/Div1 مورد ارزیابی قرار گرفته است. مواد و روش ها: مطالعه ا ز نوع مورد-شاهدی و بصورت دوسوکور انجام گرفت. برای همه نمونه ها از تکنیک مشاهده پاراکلینیکی (مشاهده پرونده ،...
Background and Aim: Unlike other bones of the head and neck, hyoid bone has no bony articulations. It is connected to mandible, cranium and pharynx through muscles and ligaments. During treatment with functional appliance in patients with class II div1 malocclusion, mandible is positioned in inferior and anterior direction. Regarding the relation between hyoid and mandibular bone, alterations o...
The chemoselective photoreduction of aldehydes in the presence of ketones was achieved using triethanolamine (TEOA) as sacrificial electron donor, proflavine (PF) as photocatalyst and [Cp*Rh(iii)(bpy)Cl]Cl (Rhcat) as mediator. The reducing agent, which reacts with the carbonyl group was found to be [Cp*Rh(iii)(bpy)H]Cl (Rh(iii)-H). Contrary to formate-based reduction, its slow photochemical in ...
A modified pH 1.0 liquid redox sulfur recovery (LRSR) process, based on reactive absorption of H(2)S((g)) in an acidic (pH 1.0) iron solution ([Fe(III)] = 9-8 g L(-1), [Fe(II)] = 1-2 g L(-1)) and electrochemical regeneration of the Fe(III)/Fe(II) catalyst couple, is introduced. Fe(II) was oxidized in a flow-through electrolytic cell by Cl(2(aq)) formed on a Ti/RuO(2) anode. pH 1.0 was applied t...
سابقه و هدف: زبان کوچک دوشاخه (Bifid Uvula) نوع خفیفی از شکاف کام است. این شکاف ممکن است بسیار جزیی بوده یا اینکه گسترش یافته و زبان کوچک بصورت دوتایی و مجزا از هم وجود داشته باشد. میزان شیوع آن 2.2-0.3 درصد است و در مردان هم 2.5 برابر شایعتر است. از نظر وراثت ممکن است الگوی اتوزومال غالب داشته باشد. این اختلال تکاملی ممکن است در سندرم های متعددی مانند Apert-Crouzon-Marfan، Pierre robin وجود دا...
Background and Aim: Among different treatments of patients with Class III malocclusion , orthopedic protraction of maxilla has been known as an effective method in mixed dentition period. The aim of this study was to evaluate the cephalometric changes of Cl III patients in mixed dentition period following face mask therapy and slow maxillary expansion.Materials and Methods: This was a before-af...
Reactions of salicylaldehyde 4-methylthiosemicarbazone (H2L) and salicylaldehyde 4phenylthiosemicarbazone (H2L) with assorted chromium(III) precusors, [Cr(H2O)6]Cl3, [Cr(H2O)6](NO3)33H2O and [Cr(H2O)6](CH3COO)3, afforded new mononuclear chromium(III) complexes of the general formula [Cr(HL)2]X (X = Cl, NO3 and CH3COO). In all isolated compounds, Cr(III) ion is coordinated by the O,N,S atoms of...
