An efficient, enantioselective synthesis of apoptolidinone has been completed, demonstrating the versatility of thiazolidinethione auxiliaries. Three propionate aldol additions and two asymmetric glycolate alkylations function to establish 8 of the 12 stereogenic carbon centers. A cross-metathesis reaction is utilized to assemble the C1-C10 trieneoate fragment and the C11-C28 polypropionate reg...
Distribution coefficients of acetic acid between aqueous phase and solvents (water-C6-C10 alcohols, butyl acetate, ether and benzene) were studied. Synergetic effect was obtained for alcohol and ester systems. A slightly positive deviation was obtained for benzene–ester mixtures. The best distribution coefficient was obtained for hexanol-butyl acetate systems. The coefficients of Redlisch-Kiste...
Two feeding trials were conducted to evaluate the influence of dietary curcumin level on fish meal replacement with poultry by-product (PBM) in a largemouth bass (Micropterus salmoides) diet. In trial I, reference diet (R) contained 400 g/kg meal, and PBM replaced 60 80% (P16 P8). II, containing 80 (P8) served as control (C), was added at 5000 10000 mg/kg (C5 C10), respectively. Replacement sig...
Temperate crops cannot grow well in the tropics without rootzone cooling. As cooling increased production costs, this experiment aimed to study the growth of various Lactuca genotypes and propose possible ways of reducing these costs, without compromising productivity. A recombinant inbred line (RIL) of lettuce and its parental lines (L. serriola and L. sativa "Salinas") were grown aeroponicall...
BACKGROUND A highly efficacious vaccine is needed for malaria control and eradication. Immunization with Plasmodium falciparum NF54 parasites under chemoprophylaxis (chemoprophylaxis and sporozoite (CPS)-immunization) induces the most efficient long-lasting protection against a homologous parasite. However, parasite genetic diversity is a major hurdle for protection against heterologous strains...
Dialkyl phthalate esters (DPEs) are widely used chemicals, with over 4 million tonnes being produced worldwide each year. On the basis of their octanol-water partition coefficients (Kow), which range from 10(1.61) for dimethyl phthalate to 10(9.46) for di-iso-decyl phthalate, certain phthalate esters have the potential to bioconcentrate and biomagnify in aquatic food webs. However, there are no...
BACKGROUND Biologically produced alkanes can be used as 'drop in' to existing transportation infrastructure as alkanes are important components of gasoline and jet fuels. Despite the reported microbial production of alkanes, the toxicity of alkanes to microbial hosts could pose a bottleneck for high productivity. In this study, we aimed to improve the tolerance of Saccharomyces cerevisiae, a mo...
BACKGROUND Medium-chain acyl-CoA dehydrogenase deficiency (MCADD) is the most common inherited defect in the mitochondrial fatty acid oxidation pathway, resulting in significant morbidity and mortality in undiagnosed patients.Newborn screening (NBS) has considerably improved MCADD outcome, but the risk of complication remains in some patients. The aim of this study was to evaluate the relations...
با اعمال مدیریتهای مناسب آبیاری میتوان میزان کاهش عملکرد محصول در اثر شوری را کاهش داد. در این تحقیق عکسالعمل چمن رقم Seashore Paspalum تحت سطوح مختلف تنش شوری متناوب و ثابت ازنظر طول ریشه و بخش هوایی، وزنتر و خشک و کیفیت چمن درکشت هیدروپونیک در گلخانه موردمطالعه قرار گرفت. آزمایش بهصورت کرتهای خردشده در قالب طرح بلوکهای کامل تصادفی با سه تکرار انجام شد. تیمارهای تحقیق شامل تیمارهای شوری...
Introduction: Cardiomyocytes apoptosis contributes to the development of left ventricular hypertrophy. The Bcl-2 family members are important regulators of mitochondrial pathway of apoptosis. Monoterpenoid phenol –carvacrol– possesses strong antioxidant properties. The present study aimed to evaluate the effect of carvacrol on transcription level of pro-apoptotic (Bad and Bax) and...
