The effects of non-enzymatic antioxidative compounds such as ascorbic acid, thiamine HCl and β-carotene were investigated on salt stressed maize plants. The maize plants were sprayed with 100 mg L of ascorbic acid, thiamine or β-carotene solutions once a week, up to harvesting of plants. The treatment of NaCl was initiated 25 days after sowing by irrigating the plants with 125 mM NaCl solution....

BACKGROUND Accurate working length determination is a pre-requisite for a successful endodontic treatment. Even with improved systems of working length measurement, different readings may be recorded in different electrolytes present in the canal. The purpose of this in vivo/ex vivo comparative study was to determine the accuracy in measuring the working length of root canal using Direct Digita...

In this study, the expansion and deformation of alkali–silica reaction (ASR)-affected concrete structures under natural environment multiaxial stress state are predicted. The performance ASR model proposed in previous research is quantitatively investigated terms relative humidity, stress, temperature dependencies based on experimental results. simulation results indicate that humidity-dependen...

Pancreatin is a biotechnological product containing an enzyme complex, obtained from porcine pancreas, that is employed in treating pancreatic diseases. Experiments regarding the stability of the pharmaceutical formulation containing pancreatin were performed using standard binary mixtures with 6 excipients in a 1:1 ratio (m/m) and a commercial formulation. To accomplish these goals, samples we...

Salinity is an abiotic stress that reduces the seed germination and productivity of tomatoes. Magnetic treatment has been shown to have a positive effect on germination, seedling growth, various crop species. Therefore, three experiments were conducted evaluate whether treating saline water or seeds with magnetic field can improve tomatoes (Solanum lycopersicum) under salinity stress. To growth...

The aim of the study is to evaluate and compare the efficacy of cetrimide on decalcifying capability of different irrigating solutions. Thirty maxillary central incisor teeth have been collected. The specimens were randomly divided into 6 experimental groups (n=10) according to tested irrigating agents. Irrigating agents consisted in different composition of EDTA and citric acid solutions, addi...

OBJECTIVE To determine the operative advantage in terms of minimizing the complications following conventional phaco surgery with dual infusion through irrigating chopper. METHODS A Randomized Controlled Clinical Trial (RCCT) was conducted in the Ophthalmology Unit-III, Sindh Government Lyari General Hospital and DUHS and Al-Noor Eye Hospital Karachi, from March 2008 to February 2009. A total...

OBJECTIVE Heat stress (HS) triggers oxidative stress and respiratory alkalosis in pigs. The objective of this experiment was to study whether a short-term supranutritional amount of dietary vitamin E (VE) can mitigate oxidative stress and respiratory alkalosis in heat-stressed pigs. METHODS A total of 24 pigs were given either a control diet (17 IU/kg VE) or a high VE (200 IU/kg VE; HiVE) die...
