Abstract Robusta beans have a bitter taste, sour and high caffeine content. coffee contains 2.2 percent caffeine, while Arabica 1.2 caffeine. The level in the can be lowered through decaffeinated process. Optimal extraction from requires heating via However, temperatures long times reduce flavor due to degradation of flavor-forming compounds, resulting with weak flavor. This research aimed enha...

Citrulline is a non-protein amino acid that acts as metabolic intermediate in the urea cycle and arginine synthesis. It present some foods, although its name derives from watermelon (Citrullus vulgaris), which it was first identified. Under normal conditions, exists zwitterion aqueous solutions since carboxylic amine groups can act Lewis donors to chelate metal cations. In addition, possesses a...

One of the key features of major histocompatibility complex (MHC) genes is the frequent occurrence of trans-species polymorphism, that is 'the passage of allelic lineages from ancestral to descendant species' (Klein et al. 2007). Selectively maintained ancestral polymorphism may, however, be hard to distinguish from introgression of MHC alleles between hybridizing species (Fig. 1). In this issu...

BACKGROUND & OBJECTIVES Leishmaniasis is a major public health problem, and the alarming spread of parasite resistance underlines the importance of discovering new therapeutic products. The present study aims to investigate the in vitro antileishmanial activity and cytotoxicity of the ethanolic extract of Berberis vulgaris fruits and chloroform extract of Nigella sativa seeds against Leishmania...

In the present study, dormancy and germination requirements were investigated in seeds of Citrullus colocynthis (L.). Seeds were subjected to 10 pretreatments in the present study.  These pretreatments included hot water (100° C) followed by the seeds placed between double layered filter paper moistened with 5 ml of distilled water and kept at 28 - 30 °C, sulphuric acid (98% v/v), for 30 min fo...

The objective of the present work was to evaluate the effect of exogenously applied cadmium on the physiological response of green algae Chlorella vulgaris. The study investigated the long-term effect (18 days) of cadmium on the levels of algae biomass, assimilation pigment composition, soluble protein, oxidative status (production of hydrogen peroxide and superoxide anion), antioxidant enzymes...

Se estudió el efecto de los niveles 20, 40 y 60 centibares (cb) potencial hídrico del agua en suelo (ψ) al momento riego, tres etapas fenológicas: vegetativa (V), floración (FL) fructificación (FR), sobre rendimiento cultivo sandía (Citrullus vulgaris Schrad) la Chontalpa, Tabasco, durante ciclo primavera verano 1998. El experimento se estableció campo empleando un diseño experimental San Crist...

The use of engineered nanomaterials has increased as a result of their positive impact on many sectors of the economy, including agriculture. Silver nanoparticles (AgNPs) are now used to enhance seed germination, plant growth, and photosynthetic quantum efficiency and as antimicrobial agents to control plant diseases. In this study, we examined the effect of AgNP dosage on the seed germination ...
