The purifi cation of a valuable product or product library after a long and complex synthesis is a very important process. The Agilent Automated Purifi cation Software introduces an Open-Access-based solution for isolating substances, with automated focused gradient to simplify the preand post-purifi cation steps. This Technical Overview describes the easy steps to follow, from crude sample ana...

Despite the many years of investigation of the thyroid, some of the most fundamental problems concerning this ductless gland are still the subject of speculation and controversy, and the certain progress which follows quantitative knowledge has not yet materialized. Since quantitative values cannot be obtained by clinical observations alone, and since pathologic studies of the glands cannot of ...

Pseudomonas tolaasii is the main bacterial pathogen of several mushroom species. In this paper we report that strains of P. tolaasii produce volatile substances inducing in vitro mycelia growth inhibition of Pleurotus ostreatus and P. eryngii, and Agaricus bisporus and P. ostreatus basidiome tissue blocks brown discoloration. P. tolaasii strains produced the volatile ammonia but not hydrogen cy...

the current study is focused on determination of the accumulation rate of cadmium (cd) and lead (pb) in the liver and muscle tissues of the caspian kutum fish. specimens were collected randomly from twelve stations in mazandaran province, the caspian sea basin, between october 2009 and march 2010. fork length, weight and length-weight relationship of samples were measured. one-way analysis of v...

In consideration of physical and chemical properties of pure substances, speed of sound is one of important quantity which can used to calculate many of other thermo-physical properties such as isothermal compressibility, Joule-Thomson coefficient, isobaric heat capacity and etc. These thermo-physical properties are the main parameters in industrial and chemical processes. Development of accura...

The Priority Data Needs documents are intended to characterize substance-specific priority data needs determined via the ATSDR Decision guide for identifying substance-specific data needs related to toxicological profiles (54 Federal Register 37618, September 11, 1989). The identified priority data needs reflect the opinion of the Agency, in consultation with other federal programs, of the rese...

Purpose: Simple and precise first derivative zero crossing spectrophotometric method has been developed for the simultaneous estimation of protein nucleic acid without prior separation. Approach: The concentration ranges were taken in range 60-140 mg mL-1 20-100 respectively 0.1 M NaOH. Absorption spectra samples recorded between 200 nm to 400 against a reagent blank. Zero-order stored individu...

The aim of the research was to study possible therapeutic effect "Argitos" in form a spray and liquid Pyridine-2-carboxaldehyde (Tryptophan2PKA) thermal burns. Studies have shown that levels blood parameters groups burn + (spray) (intraperitoneal injection -IP) differ from control group (pure burn). With IP administration tryptophan- 2PKA, tendency towards normalization higher efficiency were o...
