Tomato  (L.ycopersicon esculentum  Mill.) cv. Rio Grande  seedlings were nutritionally conditioned with solutions complete fertilizer N(60% NO3+40% NH4)-P-K (20-20-20) , N(30%NO3+70% NH4)-P-K (15-5-30) , the first two week   N(60% NO3+40% NH4)-P-K (20-20-20) and later two week  N(30%NO3+70% NH4)-P-K...

OBJECTIVE To evaluate the role of memantine (N-methyl-d-aspartate receptor antagonist) pretreatment for the prevention of spinal cord ischemia after infrarenal aortic clamping in a rabbit model. METHODS Thirty New Zealand White rabbits were divided into 5 different groups of 6 rabbits. Groups 60-7 and 60-5 received oral memantine 60 mg once a day for 7 and 5 days, respectively, and groups 30-...

The aim of this study was to determine the effect of autoclave polymerization on the transverse strength of denture base polymers. To this end, 30 rectangular test specimens were fabricated of two heat-polymerized denture base polymers. The test groups were: (I) control, i.e., conventional water bath to polymerize resins by heat at 100 degrees C for 30 minutes; (II) autoclave polymerization at ...

Abstract We examined the activities of serotonin (5-HT) neurons in dorsal raphe nucleus (DRN) and corticotropin-releasing factor (CRF) hypothalamic paraventricular (PVN) during acute treadmill running at different speeds (control, low, high) durations (15, 30, 60 min) male Wistar rats using c-Fos/5-HT or CRF immunohistochemistry. also performed elevated plus maze test (EPM) forced swim (FST) af...

AIM To evaluate the effect of metoclopramide on gastric emptying in coronary artery bypass graft (CABG) surgery patients with early enteral nutrition and to evaluate the effect of metoclopramide on motility of the gallbladder in these patients. METHODS A prospective, randomized, placebo-controlled, double-blind study of 40 patients treated at cardiosurgical intensive care unit after CABG surg...

OBJECTIVES To investigate the effects of 24 weeks of whole-body-vibration (WBV) training on knee-extension strength and speed of movement and on counter-movement jump performance in older women. DESIGN A randomized, controlled trial. SETTING Exercise Physiology and Biomechanics Laboratory, Leuven, Belgium. PARTICIPANTS Eighty-nine postmenopausal women, off hormone replacement therapy, age...

the aim of the present research was to study the effects of regular training and exhaustive exercise on t-pa/pai-1 complex in the blood of forty eight rats. they were divided randomly into control and experimental groups and the subgroups included the primary acute, secondary acute and 8-wk regularly trained (each group 8 rats). endurance training programs (five days a week, speed 15-22 m/min f...

Consider the p–system describing the subsonic flow of a fluid in a pipe with section a = a(x). We prove that the resulting Cauchy problem generates a Lipschitz semigroup, provided the total variation of the initial datum and the oscillation of a are small. An explicit estimate on the bound of the total variation of a is provided, showing that at lower fluid speeds, higher total variations of a ...

OBJECTIVE This study aimed to assess the efficiency of six protocols for cleaning-up tooth enamel after bracket debonding. METHODS A total of 60 premolars were divided into six groups, according to the tools used for clean-up: 12-blade bur at low speed (G12L), 12-blade bur at high speed (G12H), 30-blade bur at low speed (G30L), DU10CO ORTHO polisher (GDU), Renew System (GR) and Diagloss polis...

BACKGROUND Handgrip strength and walking speed predict and influence cognitive function. We aimed to investigate an exercise protocol for improving handgrip strength and walking speed, applied to patients with chronic stroke who had cognitive function disorder. MATERIAL AND METHODS Twenty-nine patients with cognitive function disorder participated in this study, and were randomly divided into o...
