PURPOSE The rate of proteoglycan synthesis was measured in the scleras of adolescent marmosets that had undergone monocular form deprivation to characterize the scleral extracellular matrix changes associated with the development of myopia in a mature primate. METHODS Form deprivation myopia was induced in adolescent marmosets by unilateral lid suture for an average of 108 days. After the lid...

Obesity is a serious health problem of 21st century. Around 1 billion adults are overweight and more than 300 million people found to be obese globally. In fact 2.6 die per year due obesity thus it has now become major reason morbidity mortality. line this few novel pyrazole derivatives (Z)-3-(4-subtituted phenyl)-2-(3, 5-dimethyl-1H-pyrazol-1-yl)-1-phenylprop-2-en-1-one (4a-f) were synthesized...

Background: Detection of hepatitis C virus specific antibodies is the initial step in chronic HCV diagnosis.  HCV NS4B is among the most immunogenic HCV antigens and has been widely used in commercial Enzyme Immunoassays (EIA). Additionally, NS4B, a key protein in the virus replication, can be an alternative target for antiviral therapy. Objectives: Development of a new method for high-level ex...

Two species of dermatan sulfate proteoglycans, called DS-PGI and DS-PGII, have been isolated from mature bovine articular cartilages. On sodium dodecyl sulfate-polyacrylamide gel electrophoresis at low ionic strength in 0.01 M phosphate the dermatan sulfate proteoglycans appeared as a single polydisperse species whose molecular weight ranged from 80,000 to 140,000. The dermatan sulfate proteogl...

Interaction of protein synthesis initiation factors with mRNA has been studied in order to characterize early events in the eukaryotic translation pathway. Individual reovirus mRNAs labeled with 32P in the alpha position relative to the m7G cap and eukaryotic initiation factor (eIF)-4A, -4B, and -4F purified from rabbit reticulocytes were employed. It was found that eIF-4A causes a structural c...

The intraventricular administration of [3H-methyl]-methionine resulted in a steady increase in carboxyl-[3H]methylated protein formation in the brain of developing rats (2-42 days). The analysis by gel filtration on Sepharose-4B of Lubrol-Px-solubilized membrane proteins, including benzodiazepine receptor proteins, revealed co-migration of carboxyl-[3H]methylated and [3H]flunitrazepam-binding p...

abstract background: accurate methods of radiation therapy dose calculation. there are different monte carlo codesfor simulation of photons, electrons and the coupled transport of electrons and photons. mcnpis a general purpose monte carlo code that can be used for electron, photon and coupledphoton-electron transport.monte carlo simulation of radiation transport is considered to be one of the ...

1. Gel filtration of the water-soluble radioactive mucus produced three radioactive fractions, fraction A excluded on Sepharose 4B, fraction B included on Sepharose 4B but excluded on Sephadex G-200, and fraction C included on Sephadex G-200. 2. The specific radioactivities of fractions A and B were the same, with fraction C a little lower, whether the material was labelled with (14)C-labelled ...

Recent analysis has shown the presence of three sequences in the C-terminal 170 amino acids of human caldesmon (domain 4) which are involved in actin binding and tropomyosin-dependent inhibition of actomyosin ATPase. Two are in domain 4b (amino acids 715-793) and one is in domain 4a (amino acids 636-714). In the present work we have compared recombinant peptides containing either domain 4a or d...

A water-soluble polysaccharide (BIWS-4b) was purified from the fruit bodies of Bulgaria inquinans (Fries). It is composed of mannose (27.2%), glucose (15.5%) and galactose (57.3%). Its molecular weight was estimated to be 7.4 kDa (polydispersity index, Mw/Mn: 1.35). Structural analyses indicated that BIWS-4b mainly contains (1 → 6)-linked, (1 → 5)-linked and (1 → 5,6)-linked β-Galf units; (1 → ...
