purification of extra-cellular cellulolytic enzymes from c e l l u l o mssp. strain 0, isolated from forest soil in the north of iran , was studied by using gel filtration and ion-exchange chromatography. two endo-glucanases (endo-i & endo-ii) and one exo-glucanase (exo-i) were purified to hornogenity . the purified enzymes had molecular weights of about 39.000,70.000 and 90.000 daltons for end...

BACKGROUND To investigate the association of DNA nucleotide excision repair (NER) defects with neurological degeneration, cachexia and cancer, we performed autopsies on 4 adult xeroderma pigmentosum (XP) patients with different clinical features and defects in NER complementation groups XP-A, XP-C or XP-D. RESULTS The XP-A (XP12BE) and XP-D (XP18BE) patients exhibited progressive neurological...

Studies delineating the dietary Val needs of modern commercial broilers are sparse. Three studies were conducted to determine the dietary Val nutrient needs of Ross x Ross 308 male broilers. Three time periods were evaluated independently, 0 to 14 d (starter), 14 to 28 d (grower), and 28 to 42 d (finisher) of age. Corn- and peanut meal-based diets for each feeding phase served to titrate the Va...

This clinical trial focused on collating the instrumentation time and quality of root canal obturation in primary molars treated with three techniques: adaptive, rotary, manual. A triple-armed, randomized controlled was performed 75 requiring pulpectomy treatment, divided into groups (n = 25 per group). The teeth Group 1 were instrumented an adaptive technique (XP-endo Shaper, FKG Dentaire, La ...

i) 8 (p;Xp) 2 TM , as p 2M ) there exists (U ; ) 2 S such that p 2 U ; i.e. (p;Xp) 2 TU , and we have TU =  1 (R) 2 . ii) If we de…ne F : TpM ! R by F (Xp) = (Xp(x); Xp(x); :::::; Xp(x)) where x; x; ::::; x are local coordinates on (U ; ), then clearly F is an isomorphism, so  (p; Xp) = ( (p); F ( Xp)); and  1 = ( 1 ; F 1 ). Now take  1 (U);  1 (V ) 2 and suppose (p; Xp) 2  1 (U)\  1 (V ...

Xeroderma pigmentosum (XP) is a rare recessive disorder that is characterized by extreme sensitivity to UV light. UV light exposure results in the formation of DNA damage such as cyclobutane dimers and (6-4) photoproducts. Nucleotide excision repair (NER) orchestrates the removal of cyclobutane dimers and (6-4) photoproducts as well as some forms of bulky chemical DNA adducts. The disease XP is...

A 2 × 2 factorial experiment was conducted to investigate the effects of cereal type (barley v. oat) and exogenous enzyme supplementation (with or without) on intestinal fermentation, and on indole and skatole levels in the intestinal content and the adipose tissue in finisher boars. The experimental treatments were as follows: (i) barley-based diet, (ii) barley-based diet with enzyme supplemen...

Xeroderma pigmentosum-Cockayne syndrome complex is a very rare multisystem degenerative disorder (Orpha: 220295; OMIM: 278730, 278760, 278780, 610651). Published information on XP-CS is mostly scattered throughout the literature. We compiled statistics related to symptom prevalence in XP-CS and have written a clinical description of the syndrome. We also drew on clinical practices used in XP an...
