important cut flowers in tropical and sub tropical areas of the world and has the seventh rate of production between all cut flowers of Iran. In order to investigate different effects of storage temperatures (8 weeks at 4 °C, 4 weeks at 4 °C + 4 weeks at 20 °C, 8 weeks at 12 °C, 4 weeks at 12 °C+ 4 weeks at 20 °C and 8 week at 20 °C) and different concentrations of gibberellic acid (0, 150 and ...

A powerlifting athlete ruptured his left tendon of the pectoralis major muscle while attempting to lift 160 kg in a Brazilian bench press championship. The injury seemed to occur in the concentric phase of exercise; however, the more common mechanism of rupture is during the eccentric phase. The tendon was reinserted to the humerus 3 weeks later with screws and washers. The athlete returned to ...

Understanding species responses to global change will help predict shifts in species distributions as well as aid in conservation. Changes in the timing of seasonal activities of organisms over time may be the most responsive and easily observable indicator of environmental changes associated with global climate change. It is unknown how global climate change will affect species distributions a...

Rapeseed (Brassica napus L.) is grown in different geographical regions of the world. It is adapted to different environments by modification of flowering time and requirement for cold. A broad variation exists from very early-flowering spring-type to late-flowering winter cultivars which only flower after exposure to an extended cold period. B. napus is an allopolyploid species which resulted ...

Oxidative stress plays an important role in the development of complications in diabetes mellitus. Antioxidant therapy has been thought to decrease oxidative stress. The objective of the present study was to explore the effects of melatonin (MLT) on oxidative stress in diabetic rat eye and brain tissue by using immunohistochemical methods. Diabetes was induced by streptozotocin, (STZ, 55 mg/kg/...

Since the biological effects of maleic hydrazide (MH) were first described by SCHOENE and HOFFMANN (4), a great many papers have appeared describing the effects of that compound on growth and flowering. NAYLOR (3) sprayed tobacco, maize and cocklebur with various concentrations ranging from .025% to .2%o and obtained either suppression or delay of visible flowering. WHITE and KENNARD (5) delaye...

In this study, 130 uniform ‘Flame Seedless’ grape trees were selected for and subjected to the same cultural practices. The sprayed three times, before flowering, during full bloom, weeks later with following treatments: control (water only), 250, 500, 750 ppm glycine; 50, 100, 150 folic acid (FA); 2%, 4%, 6% leaf moringa aqueous extract (MLAE); their combinations. High-performance liquid chrom...

Male Wistar rats were administered either (a) a high dose regime of 3,4-methylenedioxymethamphetamine (MDMA) (4 x 5 mg/kg, i.p. over 4 h on each of 2 consecutive days), (b) a moderate dose regime of MDMA (1 x 5 mg/kg on each of 2 consecutive days), (c) D-amphetamine (4 x 1 mg/kg over 4 h on each of 2 days), or (d) vehicle injections. The high MDMA dose regime and the amphetamine treatment both ...
