this experiment was conducted to study the effects of single and combined application of organic, biological and chemical fertilizers on qualitative and quantitative characteristics of vegetative part of coriander, (coriandrum sativum l.). the experiment was carried out as split plot in time based on complete randomized block design with three replications and 12 treatments at research station,...

in order to study the effect of plant density and sowing date on ear economic yield and sugar content in sweet corn (zea mays l. cv. saccarata), a field experiment was conducted at tarbiat modarres university (tehran west) in 2004. the experiment was carried out using split plots based on randomized complete block design of 4 replications. four levels of sowing date (may 22th, june 10th, july 1...

Calcium channels of the P/Q subtype mediate transmitter release at the neuromuscular junction and at many central synapses, such as the calyx of Held. Transgenic mice in which alpha1A channels are ablated provide a powerful tool with which to test compensatory mechanisms at the synapse and to explore mechanisms of presynaptic regulation associated with expression of P/Q channels. Using the caly...

OBJECTIVE We aimed to investigate the effect of pelvicaliceal anatomical differences on the etiology of lower caliceal stones. MATERIALS AND METHODS Records of adult patients between January 1996 and December 2005 with solitary lower caliceal stone were reviewed. After exclusion of patients with hydronephrosis, major renal anatomic anomalies, non-calcium stones, history of recurrent stone dis...

The localization and density of voltage-gated Ca(2+) channels at active zones are essential for the amount and kinetics of transmitter release at synapses. RIM proteins are scaffolding proteins at the active zone that bind to several other presynaptic proteins, including voltage-gated Ca(2+) channel α-subunits. The long isoforms of RIM proteins, which contain NH2-terminal Rab3- and Munc13-inter...

Introduction: Physalis alkekengi (Solanaceae) is a rich source of various antioxidants. There are some reports that show P. alkekengi has been used for treatment of a wide range of diseases including gout and inflammation. Xanthine oxidase plays a crucial role in gout. Many natural compounds such as various flavonoids have been reported to have inhibitory effect on xanthine oxidase. Metho...

The attractiveness of a plant to pollinators is dependent on both the number of flowers produced and the size of the petals. However, limiting resources often result in a size/number trade-off, whereby the plant can make either more flowers or larger flowers, but not both. If developmental genes underlying sepal and petal identity (some of which overlap) also influence size, then this shared ge...
