wheat is grown on 6.2 million hectares under different agr-climate conditions in iran. of 6.2 million hectares irrigated wheat, khazar warm humid climate regions (gorgan, mazandaran and moghan) with 350 thousand hectares are the most important wheat growing areas of the country. productive and rich lands, high rainfalls and favorable temperature and light in these regions provide good condition...

Phospholipid vesicles, also known as liposomes, were examined for their ability to act as a drug carrier to the brain. 9-Amino-1,2,3,4-tetrahydroacridine (THA), a centrally acting acetylcholinesterase inhibitor, was used as a model drug. THA was encapsulated in dehydration-rehydration vesicles (DRV) composed of egg yolk phosphatidylcholine, cholesterol and dipalmitoyl-phosphatidic acid (molar r...

in order to study the response of new sugar beet hybrids and cultivars to curly top disease in the field conditions, an experiment was carried out in a randomized complete block design with four replications and sixteen treatments in 2007 in fasa. each plot included a hybrid or cultivar planted in three rows with eight meter length and 50cm between- row spacing. after weeding and first thinning...

CONTEXT The two-incision approach to total hip arthroplasty (THA) has received increasing attention in recent years. However, the benefits of this procedure have been debated. OBJECTIVES To evaluate the two-incision THA technique compared to the standard anterolateral THA approach in a community hospital setting. METHODS A retrospective review of records from patients who had THA at Memoria...

ions and is widely used to determine the activity and concentration of hydrogen ions. Metal ion-selective electrodes, such as potassium ions and calcium ions, are also commercially available. Drug ion selective electrodes are prepared and are used to determine the concentrations of drug ions. Other applications of drug ion electrodes include studies of protein binding of drug ions, mechanisms o...

INTRODUCTION Although total hip arthroplasty (THA) is superior to bipolar hemiarthroplasty (BHA) for displaced femoral neck fracture in terms of hip pain, function and reoperation rate, THA has a higher rate of dislocation. The direct anterior approach (DAA) and a dual mobility cup (DMC) are associated with lower rates of dislocation. The aim of this study was to investigate the outcomes of THA...

Abstract In these lectures, starting with a review of secondand coherent-state path-integral quantization, we will formulate a quantum field theory of bosonic matter and will study its thermodynamics and correlation functions. We will explore the transition to Bose-Einstein condensation (BEC) of noninteracting bosons. Including interactions, we will study the properties of a superfluid and a ph...


 Tha?bit b. Qurra (d. 288/901), a Sabian of H?arra?n, and his descendants remained in their ancestral religion for six generations. Why did they persist despite pressure to convert? This article argues that religious self-identification as could be distinct advantage Baghdad’s elite circles. It focuses on Tha?bit’s great-grandson Abu?

In animal the plasma cholesterol-lowering activity of 2,4,6-trihydroxyacetophenone (THA) is due to enhanced cholesterol 7alpha-hydroxylase (CYP7A1) activity. We have examined the effect of THA on CYP7A1 activity and mRNA level in HepG2 cells. THA stimulated CYP7A1 activity in a concentration- and time-dependent manner. After exposure for 24 h, 1 muM THA induced CYP7A1 activity 160+/-8% and mRNA...

Phloracetophenone (2,4,6-trihydroxyacetophenone, THA) is a potent choleretic in the bile fistula rat, although the mechanism is unknown. In the present study, we examined how THA enhances bile secretion. Stepwise infusions of THA (1-4 micromol/min) in the isolated perfused rat liver resulted in an immediate and dose-dependent increase in bile flow (BF), which reached saturation. The increase in...
