Spermatogenesis is the most important stage in male fertility. In the present study, many factors affecting spermatogenesis were evaluated in seminal plasma and homogenates of sperms from fertile and infertile males. The levels of some heavy metals, malondialdehyde (MDA) and reduced glutathione (GSH) as well as superoxide dismutase (SOD) activity were measured in both seminal plasma and homogenate supernatant of sperm from fertile and infertile males. Two hundred and sixteen human semen samples

Nanosized magnesium ferrite MgFe2O4 was synthesized using sol-gel auto combustion method as a burnt powder calcined at different temperatures (350, 500, 650, 800 and 950 C˚). These powders were pressed into a disk shape compact, and sintered at 1100 C˚ for 3 hours. The X-ray diffraction patterns of the ferrite powders showed the formation of spinal cubic structure, whereas the crystallite size increased with increasing calcined temperatures from 29 to 42 nm. The absorption bands of the FTIR spec

Use of dyes is increasing day by day due to its multiple applications in different industries. The result is dye contaminated rich colored water, which not only produces aesthetically unpleasing effect but also creates serious environmental concerns. In present study, competent algae were isolated from wastewater streams and were tested for their efficiency to remove color from the dye contaminated wastewater. It was observed that three strains were capable of removing color from the wastewater.

In this work, highly selective molecularly imprinted polymers (MIPs) of propranolol on the internal surface of hollow fiber were prepared. The resulting MIP coated MNP were used as dispersive solid phase micro extraction (SPME) fiber coupled with HPLC-UV for the selective extraction and detection of propranolol. Encouraging result was obtained. Method was evaluated and enrichment factors, relative standard deviations and linearity ranged for propranolol 918.8, 2.9% and 25-3000 ng.ml-1 were obtai

One of the main indicators determining the potential of a nation is the health of its younger generation. The present study was conducted in a kindergarten in Karaganda, Kazakhstan. 139 children (their age ranged from 4 years to 5 years and 5 months) were the participants of this study who were divided into two groups of children with neurosis and a group of healthy children. The results indicated that the lack of essential metals in children with neuroses explained one of the mechanisms of the

New azo and diazo dye was synthesized by coupling reaction of dizonium salt of P-amino acetophenone, P-phenylene diamine with phenolic derived. The products were characterized by FTIR and 1H NMR; they were identical to literature. A1, A2, A4, A5, B2 and B3 were used dyes in dying process which were applied on wool, cotton and sawdust. We note that there are variations in the hues of the dyed fabrics which is resulted from the modifications in the coupling components. All the dyes gave color chan

Aims: The purpose of this study was to evaluate the effectiveness of Acceptance and Commitment-Based Therapy (ACBT) on anger, anxiety and hostility in heart surgery patients. Materials and Methods: The present study was quasi-experimental (pre-test, post-test) with experimental and control groups. A follow-up test was conducted two months after the post-test. The statistical population consisted of all patients referring to Vali-e-Asr Hospital in Ghaemshahr during January-February 2017 having a

In this study, the effect of TiO2 nanoparticles (NP) was evaluated on the essential oil of rosemary plant (Rosmarinus officinalis). The experimental treatment included spraying seven doses of TiO2 NPs (0 (control), 20, 40, 60, 100, 200, and 400 ppm) on the rosemary leaf. The results indicated that the use of TiO2 NPs significantly affected the quantity of rosemary essential oil. The peak area for most of the compounds increased with the application of TiO2 NPs. However, at high concentrations of

Background: Moringa has been the most spread and extensive species in the world, which makes this tree important in the economic field because of having nutritional and medical properties. Various kinds of fresh fruit juice, especially orange (Citrus sinensis) juice has been very desirable for the consumers because of its delicious flavor, however, its shelf life is less than 3 days at 4±1°C. Objective: to evaluate the sensorial, physicochemical and microbiological properties of the M

Introduction and Objectives: Today, a large number of people visit the dental clinics with anxiety and this is significantly increasing. It seems that the origin of this anxiety is the negative experience of people in the past which is the most important reason for the emergence of this fear and anxiety from dentistry. Therefore, in this study, the reduction in anxiety was compared through medication and giving awareness and relaxation to patients visiting the dental clinic. Method: In this stud

This study was conducted to evaluate okra pods’ quality to reduce the pesticides’ residues of indoxacarb, fenarimol, acetamiprid and chlorfenapyr by using different processes such as water washing, boiling, steaming and chemical solution for 3, 5 and 7 min. After that, the treated okras were cooked. Chemical analyses were done in okra pods raw okras after different processes. The mineral contents were determined in okra pod as raw materials. Peroxidase, color, percent of penetration
