Guayule (Parthenium argentatum Gray) is now a commercial crop for the production of high-quality, hypoallergenic natural rubber latex. Because guayule is relatively resistant to both insect and disease pests, its cultivation requires little chemical input. It has been postulated that guayule...

The crystal and molecular structure of l-pyroglutamyl-β-(2-thienyl)-l-alanyl-l-prolinamide,

1.1. TRH and acid TRH were submitted to pyroglutamate amino peptidase digestion in vitro. The resulting cyclized compound corresponding to diketopiperazines of His-Pro were identified on paper electrophoregrams.2.2. The pseudo-hormones: Pyroglutamyl-Histidyl-Amphetamine, Pyroglutamyl-Histidyl-pr...

A glycosyltransferase gene, rhoG, involved in the biosynthesis of the anthracycline antibiotic β-rhodomycin was isolated as a 4.1-kb DNA fragment containing rhoG and its flanking region from Streptomyces violaceus by degenerate and inverse PCR. Sequencing analysis showed that rhoG was located i...

In the present work an attempt has been made to study the flow behavior of AA 2014 Al alloy containing 10% wt silicon carbide particle of size 20-40 microns. The flow behavior is investigated from room temperature up to 5000C and the strain rate 0.01 to 100 per second. Also, the microstructure a...

BackgroundAmyloid A (AA) amyloidosis is a multisystemic, progressive, and severe disease. Renal involvement is a prominent feature of the disease, and the outcome of patients on dialysis is poor. We aimed to analyze the outcomes of kidney transplantation in patients with AA amyloidosis in compar...

This study used the copolymer emulsion method to synthesize colloidal monodisperse core/shell microspheres composed of the poly(styrene-co-methyl methacrylate-co-acrylic acid) [Poly(St-MMA-AA)]. Colloidal photonic crystal (CPhC) films have prepared by using polymer composite microspheres and suc...

Background and aimsCoronary computed tomography angiography (CCTA)-verified high risk plaque (HRP) characteristics including positive remodeling and low attenuation plaque have been associated with acute coronary syndromes. Several studies reported that the n-3 polyunsaturated fatty acids have b...

This paper investigates Japanese particles a and aa in responsive turns. Although both of these tokens display change-of-state of the speaker's cognitive state, they mark different types of epistemic stance. Through analysis of collocating items and sequential environments, it is shown that...

The objective of this work is to improve the hardness and reduce the wear rate of AA 2014 by reinforcing Silicon Carbide (SiC) onto the surface of the base material using Gas Tungsten Arc (GTA) as a heat source. Reduction of hardness on the base metal is observed after the application of heat us...

Trifluoroacetic acid (TFA) is released in the atmosphere through its use in the chemical industry and as degradation product of chlorofluorocarbon (CFC) alternatives like hydrofluorocarbons and hydrochlorofluorocarbons. In the present study, we have investigated the OH formation dynamics in the ...

In normal rats, consecutive administrations of AA-193 for 7 days maintained the dose-dependent uricosuric activity without significant changes of the plasma urate level. In clearance studies, AA-193 produced an increase in the fractional excretion of urate (FEua) namely an inhibition of the net ...

The present study was undertaken to develop a novel method for the enzyme labeling of antibodies. Goat anti-rabbit IgG was used as a prototype and coupled to β-D-galactosidase (Gal) with a new heterobifunctional cross-linking agent N-[β-(4-diazophenyl)ethyl]maleimide (DPEM). The antibody was f...

A heterobifunctional crosslinking agent N-[β-(4-diazophenyl)ethyl]maleimide (DPEM) was newly synthesized and characterized to possess the maleimide group with a stability greater than that previously reported for N-(4-diazophenyl)maleimide. Using the peptide hormone neurotensin (NT) as a model ...

A newly synthesized ethyl 2-cyano-3-[5-(phenyl-hydrazonomethyl)-1H-pyrrol-2-yl]-acrylate (ECPHPA) has been characterized by experimental measurements. The theoretically calculated results are in accordance with the experimental studies. All calculations have been performed using B3LY/6-31G(d,p) ...

A novel glycidylamine epoxy resin containing phthalide cardo structure (TGMP) was designed and synthesized based on o-cresolphthalein using a three-step procedure. Its curing systems were prepared using methyl-nadilic anhydride (MNA) and 2-ethyl-4-methylimidazole (EMI-24) as the curing agent and...

Rationale and Objectives.A biodegradable radiopaque particulate contrast agent formulated from cyclic carbonate of ioxilan (IXC), which is a prodrug of nonionic water-soluble contrast ioxilan, recently has been developed. This contrast agent enhances liver attenuation and is cleared from the bod...

N(α)-(2-Oxo-2H-1-benzopyran-4-yl)Weinreb-α-aminoamides were prepared from 4-chlorocoumarin and α-aminoacid derivatives. Their reaction with organometallic compounds (RLi or RMgBr) and subsequent cyclization of ketones thus obtained, give [1]benzopyrano[4,3-b]pyrrol-4(1H)-ones. Starting from p...

This study investigated the inhibitory effects of aqueous extracts from Miracle Fruit leaves (AML) on mutation and oxidative damage. The results showed that AML in the range of 1–5 mg/plate inhibited the mutagenicity of 2-aminoanthracene (2-AA), an indirect mutagen, and 4-nitroquinoline-N-oxide...

High sugar consumption has been related to several chronic diseases and thus, many alternative sweeteners have been extensively researched. However, there is still controversy regarding the harmful effects of their consumption, mainly regarding the use of artificial sweeteners, controversy which...
