A hybrid of sweet corn, Zea mays L. (;1720'; Rogers Brothers Seed Co.), was found to be comprised of glycinebetaine-positive and glycinebetaine-deficient individuals in a 1:1 mixture. This phenomenon was traced to segregation for a single, nuclear, dominant gene determining leaf glycinebetaine content within the female inbred parent of this hybrid. Selection for homozygous recessive (glycinebet...

Halophilic microorganisms inhabiting hypersaline environments such as salt lakes, Dead Sea, or evaporation ponds, have acquired specific cell adaptation to grow within stressful conditions. In this study, we isolated heterotrophic and autotrophic from several saltern ponds located at the Natural Reserve “Saline di Trapani e Paceco”, Sicily, Italy. The aim of study was investigate biotechnologic...

NMR-based metabolic profiling of polar extracts somatic embryogenic and organogenic cultures the medicinal plant Cymbopogon schoenanthus subsp. proximus were studied. Regeneration through embryogenesis was done on media containing 2,4-D BAP while organogenesis achieved NAA BAP. Fifty-two metabolites identified in calli (EC), (OC), regenerated shoots (ES), (OS). Chemometrics cluster analysis use...

Green coffee bean quality and biochemistry are influenced by environmental variables. The present study was designed to the influence of soil temperatures chemistry on physical attributes, (assessed three internationally trained, experienced, certified Q-grade cuppers licensed Specialty Coffee Association (SCA) Quality Institute (CQI) green beans). performed in 53 farms southwest Ethiopia distr...

The history of coffee goes back to the 10th century. Currently, is a widespread drink, with recent studies reporting global consumption 164,9 million 60-kg bags in 2020/2021. effect on human health has been studied for many years. active ingredients include polyphenols, lactones, diterpenes, niacin, trigonelline (vitamin B3 precursor), magnesium and potassium. Potential factors that could chang...

The prevalence of obesity is increasing worldwide, with high fat diet (HFD) as one of the main contributing factors. Obesity increases the predisposition to other diseases such as diabetes through various metabolic pathways. Limited availability of antiobesity drugs and the popularity of complementary medicine have encouraged research in finding phytochemical strategies to this multifaceted dis...

Article history: Received on: 13/08/2013 Revised on: 05/09/2013 Accepted on: 22/09/2013 Available online: 30/09/2013 The objective of the present study was to investigate therapeutic efficacy of standardized fenugreek seed extract with trigonelline as marker (SFSE-T) in experimental urolithiasis in rats. Effects of subacute oral treatments of SFSE-T (30 and 60 mg/kg) and reference anti-urolithi...

The responses of Hypericum perforatum root cultures to chitosan elicitation had been investigated through (1)H-NMR-based metabolomics associated with morpho-anatomical analyses. The root metabolome was influenced by two factors, i.e., time of culture (associated with biomass growth and related "overcrowding stress") and chitosan elicitation. ANOVA simultaneous component analysis (ASCA) modeling...

In the course of experiments designed to elucidate the structure of reduced diphosphopyridine nucleotide (DPNH) (12), it became necessary to prepare the 2and 6-pyridones of iV-methylnicotinamidel by oxidation of the latter. Huff (5) has described the preparation of N’-methyl-6-pyridone-3-carboxylic acid by alkaline ferricyanide oxidation of either trigonelline or N’-methylnicotinamide. The acid...

Type 2 diabetes mellitus is a metabolic disease characterized by persistent hyperglycemia. High blood sugar can produce long-term complications such as cardiovascular and renal disorders, retinopathy, and poor blood flow. Its development can be prevented or delayed in people with impaired glucose tolerance by implementing lifestyle changes or the use of therapeutic agents. Some of these drugs h...
