India is still by far the major producer of various fruit crops, but its relative share in the world production has been gradually declining. Alternate bearer fruit cultivars present a serious economic problem to fruit growers. An alternate bearing plant is the one that does not bear a regular crop year-after-year; rather heavy yields are followed by extremely light yield. This complex phenomen...
Over recent decades, shifts toward translational or applied research in many countries have come at the expense of fundamental discovery research. Here we discuss historical importance basic science cardiovascular field, risks its decline and ongoing need for a strong foundation
the cotton bollworm, helicoverpa armigera (hübner), is one of the important polyphagous pests causing serious loss to many economically important crops in iran. the goal of this experiment was to study the age-stage, two-sex life table of h. armigera on different bean cultivars including white kidney bean (cultivars daneshkadeh, pak, and shokufa), red kidney bean (cultivars akhtar, naz, and say...
Cellular oxidation index has emerged as an important determinant in defining the fate of a living cell and its susceptibility to disease. Oxidative stress targets include oxidation of DNA, protein and lipids; causing cellular oncogenesis, chronic diseases and premature senescence. The possibility that dietary intervention via nutrition-enriched food may significantly decrease incidence of diet-...
Conversion of native prairie to agriculture has increased food and bioenergy production but decreased wildlife habitat. However, enrollment of highly erodible cropland in conservation programs has compensated for some grassland loss. In the future, climate change and production of second-generation perennial biofuel crops could further transform agricultural landscapes and increase or decrease ...
Reticular basement membrane (RBM) thickness and airway responses to inhaled methacholine (MCh) were studied in perennial allergic asthma (n = 11), perennial allergic rhinitis (n = 8), seasonal allergic rhinitis (n = 5), and chronic obstructive pulmonary disease (COPD, n = 9). RBM was significantly thicker in asthma (10.1 +/- 3.7 microm) and perennial rhinitis (11.2 +/- 4.2 microm) than in seaso...
