Electrochemical determination of the antipsychotic medication clozapine by a carbon paste electrode modified with a nanostructure prepared from titania nanoparticles and copper oxide

A nanostructure was prepared from titania nanoparticles and copper oxide (TiO2NP@CuO) and used to modify a carbon paste electrode (CPE). The modified CPE is shown to enable sensitive voltammetric determination of the drug clozapine (CLZ). The sensor was characterized by various techniques and some key parameters were optimized. Under the optimum conditions and at a working potential of 0.6 V (vs. Ag/AgCl), the modified CPE has two linear response ranges, one from 30 pmol L�1 to 4 nmol L�1 of CLZ, the other from 4 nmol L�1 to 10 μmol L�1. The detection limit is as low as 9 pM. The transfer coefficient (α) and catalytic rate constant (kcat) were calculated and the reliability of the sensor was estimated for CLZ sensing in real samples where it gave satisfactory results.

Effects of the Dietary Approaches to Stop Hypertension (DASH) Eating Plan on Cardiovascular Risks Among Type 2 Diabetic Patients: A randomized crossover clinical trial

Objective: To determine the effects of the Dietary Approaches to Stop Hypertension (DASH) eating pattern on cardiometabolic risks in type 2 diabetic patients. Research design and methods: A randomized crossover clinical trial was undertaken in 31 type 2 diabetic patients. For 8 weeks, participants were randomly assigned to a control diet or the DASH eating pattern. Results: After following the DASH eating pattern, body weight (P = 0.007) and waist circumference (P = 0.002) reduced significantly. Fasting blood glucose levels and A1C decreased after adoption of the DASH diet (−29.4 ± 6.3 mg/dl; P = 0.04 and −1.7 ± 0.1%; P = 0.04, respectively). After the DASH diet, the mean change for HDL cholesterol levels was higher (4.3 ± 0.9 mg/dl; P = 0.001) and LDL cholesterol was reduced (−17.2 ± 3.5 mg/dl; P = 0.02). Additionally, DASH had beneficial effects on systolic (−13.6 ± 3.5 vs. −3.1 ± 2.7 mmHg; P = 0.02) and diastolic blood pressure (−9.5 ± 2.6 vs. −0.7 ± 3.3 mmHg; P = 0.04). Conclusions: Among diabetic patients, the DASH diet had beneficial effects on cardiometabolic risks

"Helicobacter Pylori Attachment To 7 Mamalian Cell Lines "

Background and Aim: Helicobacter pylori is the etiologic agent of chronic –active gastritis, gastroduodenal ulcers in humans, and a co-factor in the occurrence of gastric cancer and mucosa-associated lymphoid tumors, Adhesion of H.pylori to the gastric mucosa is a critical and also initial step in the pathogenesis of the disease. Bacterial adhesion inhibitory agents provide a novel pharmacologic approach to the management of infectious diseases. Materials and Methods: 22 H. pylori strains, isolated from the antral biopsies of 49 patients with dyspepsia, gastritis, gastric ulcer, duodenal ulcer,…were assayed by ELISA (UPR)to investigate the diversity of attachment to 7 mamalian cell lines. Results: The concentration of H.pylori and cell suspention ,the condition and temperature, can alter the attachment rate.Best bacterial concentration was equal to 1 Mc farland,and for cell suspension was 5*10 cells/ml.90 minutes in 37C incubation period result in maximum attachment. H.pylori can attach to all 7 cell lines, there are no significant differences between 22 H.pylori strains in attachment to cells. The attachment pattern of H.pylori to the cells showed significant reduction respectly from HepII, HeLa, SW742, AGS,HT29/219, HT29 to Caco-2.Maximum attachment were seen to HepII, HeLa and SW742 cells, and among these HepII was the best cells for this purpose. Conclusion: Our studies suggest that Hep II, HeLa and SW742 cells could serve as a suitable in-vitro model for the study of H.pylori adhesions, attachment, inhibition of attachment and detachment assays and among these Hep II cell is prefer recommended

Studying radon concentration in drinking water resources in Zarand city (Iran) and its villages

The concentration of dissolved radon gas was measured using the RAD7 device in drinking water sources in Zarand city and its villages. The mount of radon in drinking water sources was in the range of 5.16�14.4 BqL�1. The effective dose in all cases was less than the recommended maximum dose of 100 μSvY�1 by the WHO. Very poor linear relationship was found between the depth of wells and the radon concentration of the samples. © 2020, Akadémiai Kiadó, Budapest, Hungary

Effects of Flexibility Exercise and Supplement Vitamin B6 on Primary Dysmenorrhea in Female Non-Athletes

Background & aim: Primary dysmenorrhea or painful menses in women's medicine is one of the most common complaints that are associated with physical and psychological symptoms. The aim of this investigation was to study the effects of an eight week flexibility exercise and use of vitamin B6 on physical and psychological symptoms of primary dysmenorrhea in non-athlete females. Methods: In this clinical trial study, 60 non-athlete females, were randomly divided into 4 groups control, exercise, vitamins and exercise plus vitamin. They engaged in an 8-week exercise program that includes flexibility training, stretching the abdominal muscles, lower back, hamstrings and pelvis and hip stretches. Eight movements, each movement with 3 times repetition and each repetition lasting 10 seconds during 4 days per week was performed. The vitamins group used 2 tablets of 40 miligaram B6 vitamin daily during the 8 week program starting 2 weeks before menstruation to 3 days after menstruation. In the exercise with vitamin group, during the 8 weeks of flexibility traininig program females used from 2 weeks before menstruation to 3 days after menstruation 2 tablets of 40 miligaram B6 vitamin daily. The control group had no intervention. Before and after eight weeks, participants completed the menstrual disorders’ questionnaire. Data were analyzed. Results: Significant decreases in average of physical symptoms(exercise from 28/4 to 6/7,vitamin from 25 to 9/35,training with vitamin from 27/66 to 4/40) and psychological symptoms (exercise 25/86 to 5/93,vitamin 24/99 to 3/53,training whith vitamin 27/73 to 3/36) was observed. But physical and psychological symptoms in post-test of exercise group with vitamin had a significant decrease as compared wih other groups (p≤0/05). Conculusion: 8 weeks of flexibility and vitamin B6 usage may reduce the physical and psychological symptoms of dysmenorrhea.

The Epidemiologic, Clinical and Laboratory Findings of Patients with Guillain Barre´ Syndrome in Southern Iran Since 2007 to 2012

Background ;Objective: Guillain Barre´ syndrome is an autoimmune neuropathy which is considered to be the most acute areflexic paralysis with albuminocytologic dissociation.1 Areflexia or hyporeflexia, pain in limbs, autonomic dysfunction, progressive bilateral and symmetric weakness of limbs, numbness and paresthesia are described as the clinical features of GBS.Nevertheless, with having less prognosis, the treatment is usually effective. Most patients diagnosed with GBS were previously infected with CMV or C.jejuni. Subtypes of the disease are either Axonal or Demyelinating. Due to increase use of Guillain Barre´ in south of Iran, the present study has done a retrospective study on the epidemiology of Guillain Barre in the south part of Iran.Materials & Methods: We performed our retrospective study in Namazi hospital in Shiraz, Iran. Medical records were analyzed using computer and were presented through percentages.Results: 214 patients were studied in which 119(55.6%) of them were men and 95 (44.4%) of them were women. 15 % of the participants had respiratory disturbance and 5.1% of them had histories of common cold and 1.4 of them were vaccinated before the study. Moreover, six people had died but 208 patients were treated and healed either by prescribed dosage of IVIg (69.2%) or plasmapheresis (24.3%) and one patient was also seen who had HIV virus.Conclusion: This study provides more details on the epidemiology of GBS in Shiraz, and south of Iran. Our study also revealed the difference in pattern of GBS in Iran and other countries. however, there is still a need for further clarification of the issues
