The Bethlem myopathy, a childhood onset autosomal dominant myopathy with joint contractures, has recently been localized to 21q in a series of Dutch families and the alpha 1 and alpha 2 subunits of type VI collagen (COL6A1 and COL6A2) have been postulated as candidate genes. We investigate a large family of French Canadian descent (family 1489) in which the Bethlem myopathy is segregating. Fami...
Extensive use of chromium (Cr) and arsenic (As) based preservatives from the leather tanning industry in Pakistan has had a deleterious effect on the soils surrounding production facilities. Bacteria have been shown to be an active component in the geochemical cycling of both Cr and As, but it is unknown how these compounds affect microbial community composition or the prevalence and form of me...
اثر تابش گاما بر ظرفیت جذب و تغییرات ساختاری کلینوپتیلولیت طبیعی و فرم های تبادل یونی شده آن مورد بررسی قرار گرفت. این زئولیت طبیعی به وسیله ی روش های پراش سنجی اشعه ی ایکس(xrd) و فلورسانس اشعه ی ایکس(xrf) بررسی گردید که عمدتاً از کلینوپتیلولیت تشکیل شده است. شکل های اصلاح شده ی پتاسیمی، سدیمی، کلسیمی، سزیمی ونقره زئولیت تهیه گردید و ظرفیت جذبی آن ها برای حذف توریم و کروم (vi) از محلول های آبی ت...
background and aims: chromium is considered as one of the important environmental pollutants. there is high concentration of chromium in the wastewater of electroplating industries. magnetic iron nanoparticles are used to control and eliminate heavy metals from industrial effluents through the mechanisms of adsorption, ion exchange and electro-static forces. the aim of this study was to evaluat...
background: salmonella enterica serovar typhi (s. typhi) the cause of the acute febrile disease typhoid fever is the major public health problem in developing countries. asymptomatic carriers are the main sources of typhoid. the aim of this study was to investigate methods for isolation and identification of s. typhi in asymptomatic carriers. materials and methods: two hundred stool samples wer...
این تحقیق با هدف مطالعه حذف الکتروشیمیایی کروم (vi) از محلول آبی با استفاده از سیستم الکترودی دو قطبی طراحی و انجام شد. فرایند الکتروکواگولاسیون از جمله تکنولوژی هایی است که اخیراً مورد توجه بسیاری از محققان قرار گرفته است. این روش با توجه به مزایای آن از قبیل راندمان بالا، عدم نیاز به افزودن مواد شیمیایی، حجم کم لجن تولیدی، قابلیت کنترل فرایند در شرایط مورد نظر و سهولت بهره برداری و حفظ و نگهدا...
Oral-Facial-Digital Syndrome type VI (OFD VI) represents a rare phenotypic subtype of Joubert syndrome and related disorders (JSRD). In the original report polydactyly, oral findings, intellectual disability, and absence of the cerebellar vermis at post-mortem characterized the syndrome. Subsequently, the molar tooth sign (MTS) has been found in patients with OFD VI, prompting the inclusion of ...
The adsorption ability of Dowex Optipore L493 resin modified with Aliquat 336 (MR), activated carbon modified with Aliquat 336 (MAC) and sawdust modified with Aliquat 336 (MS) for removal of Cr(VI) from aqueous solution in batch system was investigated. The effects of operational parameters such as adsorbent dosage, initial concentration of Cr(VI) ions, pH, temperature and contact time were stu...
ABSTRACT In this research which was performed with bench Scale, Adsorption of Cr(VI) from Industrial wastewater was studied & biological method of Activated sludge batch flow reactors utilized. This study indicated that Cr(VI) at first adsorped with cell walls of bacteria & then after Sedimentation it was intered to sludge & finally was removed from effluent. In this study Cr (VI) adsorption ...
conclusions to solve the above mentioned difficulties, fundamental study most be carried out to discover the novel methods of ferrate(vi) production, focusing on increasing the product stability and the production yield. results despite the existence of these technologies, there is no full-scale application of ferrate(vi) in the water and wastewater industry which it is due to difficulties asso...
