It is widely reported that derivatives of sugar moieties can be used to metabolically label cell surface carbohydrates or inhibit a particular glycosylation. However, few studies address the effect of substitution of the cytidylmonophosphate (CMP) portion on sialyltransferase activities. Here we first synthesized 2'-O-methyl CMP and 5-methyl CMP and then asked if these CMP derivatives are recog...
در این تحقیق تأثیر حذف و کاهش نسبی سیلیکاتسدیم و جایگزینی کمپلکس آلی Sulvy-x بر ویژگیهای نوری خمیرهای کاغذCMPرنگبری شده با پروکسیدهیدروژن مورد بررسی قرار گرفت. با افزایش درصد مصرفی سیلیکاتسدیم از 3-7/0 درصد، روشنی کاغذها تا 8/66% افزایش یافته و میزان زردی به 22% و ماتی به حدود 80% کاهش یافت.همچنین با حذف کامل سیلیکاتسدیم و استفاده از ماده Sulvy-xدر سطوح مختلف 4/0، 5/0، 7/0 و1 درصد، بیشتری...
The 2-(4-chlorophenoxy)-2-methylpropionic acid (CMP) salt of chitosan (CS), CS-CMP, and that of a CS derivative (CP), were prepared and their ability to adsorb bile acids investigated. CS-CMP and CP-CMP rapidly adsorbed taurocholate (TCA) and glycocholate (GCA) when these bile acids were present together in the medium, with simultaneous release of CMP. A secondary bile acid, taurodeoxycholate, ...
در این پژوهش اثر افزودن سه نوع سورفکتانت غیریونی با نامهای تجاری PEG-1000، KELA-2 و KECA-20 در چهار سطح 1%، 2%، 3% و 4%بهعنوان افزودنی فرایند خمیرسازی CMP بر ویژگیهای خمیرکاغذ CMP به دست آمده از اکالیپتوس کاملدولنسیس، رنگبری اکسایشی خمیر و ویژگیهای کاغذ دستساز ...
BACKGROUND Little is known about the association between parental chronic musculoskeletal pain (CMP) and occurrence of CMP in the adult offspring. The main objective of this study was to assess the parent-offspring association of CMP, and also to examine possible modifying effects of age and sex. METHODS The study includes 11 248 parent-offspring trios from the Norwegian HUNT Study with infor...
An enzymatic activity responsible for the hydroxylation of CMP-NeuAc into CMP-N-glycolylneuraminic acid (CMP-NeuGc) was found in the cytosolic fraction after cellular fractionation of the mucosa of rat small intestine. It was maximum in the presence of NADPH or NADH, but it was reduced by 50% by addition of 1 mM EDTA. The Km value for CMP-NeuAc was 0.6 microM. The CMP-NeuAc hydroxylase activity...
In commercial maize, there are at least two different alleles of the chiA gene that encode alloforms of ChitA chitinase, a protein that is abundant in developing seed. Both known alloforms are modified by Bz-cmp, a chitinase-modifying protein (cmp) secreted by the fungal pathogen Bipolaris zeicola. One alloform (ChitA-B73) is also modified by Stm-cmp, a protein secreted by the fungal pathogen S...
Cartilage matrix protein (CMP) is a major component of the extracellular matrix of nonarticular cartilage. The structure and chromosomal location of the human gene encoding CMP was determined by molecular cloning analysis. We used a partial chicken CMP cDNA probe to isolate three overlapping human genomic clones. From one of these clones, a probe containing 2 human CMP exons was isolated and us...
امروزه جلبکها از نظر بوم سامانههای دریایی به عنوان تولیدکنندگان و اولین زنجیره دریافت انرژی از خورشید محسوب میشوند. به این صورت تضمین کنندهی انرژی بسیاری از آبزیان برای زندگی هستند. در تقسیمات جهانی گیاهی، جلبکها 1800 جنس و 21000 گونه دارند. جلبکها بهدلیل حضورشان در هوا تا آبهای زیرزمینی، عرصه وسیعتری را در مقایسه با سایر رستنیها به خود اختصاص میدهند. بر اساس مطالعات انجام شده، تنوع ...
Cardiomyopathy (CMP) is a heterogeneous disease caused by a functional abnormality of the cardiac muscle. CMP is of 2 major types, dilated and hypertrophic, and is further classified as either primary or secondary. Secondary CMP is caused by extrinsic factors, including infection, ischemia, hypertension, and metabolic disorders. Primary CMP is diagnosed when the extrinsic factors of secondary C...
