In some places with hard winters, the heat from sunlight and stored in the soil may not be enough to heat the greenhouse. In such a situation, the additional heat needed must be provided by heating systems. The purpose of this study is to evaluate the effectiveness of the heating system in a glass greenhouse with side air vents and mechanical fans in both night and day periods. In this study, seven different greenhouse designs have been investigated in two periods, day and night. In the daily period, by changing the pressure of the fans, tried to obtain the best condition for providing the appropriate temperature in the greenhouse. Also, in this period, the effect of sunlight on the flow field and temperature changes inside the hall were also investigated. In the night period, the amount of temperature changes by opening and closing the side valves and changing the temperature of the hall floor has been studied. The results of the research show that a greenhouse with a pressure difference of 100 pascal during the day and a greenhouse with a floor temperature of 323.15 K and side vents closed at night have more suitable conditions for growing plants in the off-season.

The aim of this study was to investigate the feasibility of producing a pastilles based on dates puree and concentrated whey and optimizing its formulation. In order to optimize the production conditions of pastilles based dates and concentrated whey,response- surface methodology was used.In this study,the conditions of production of pastilles product(concentration of xanthan gum (0.1-0.5%)and agar(0.3-0.9%) as well as concentration of whey(5-15%)were optimized to achieve maximum protein and total acceptability and total color index.According to the results of the statistical analysis of the data,a linear model for moisture, water activity, pH and total color index and a quadratic model for total acceptability were selected.The results showed that the concentration of whey had a significant effect on all responses.Increased concentration of whey had a positive effect on moisture of the samples and had a reverse effect on water activity,pH and total color index.The overall acceptability index did not show a steady trend,with a 10% increase in concentrated whey increasing and then decreasing.As the xanthan gum and agar gum content increased, the moisture content of the samples increased,but water activity decreased.The overall acceptability index also showed the highest value in average percentages for the two gums(as was the case for whey).The optimum operating conditions obtained for the jelly production process included xanthan gum concentration of 0.36% (w / w),agar gum concentration of 0.46% (w / w) and concentrated whey 13.92% (w / w).The predicted responses under these conditions were 36.62% moisture content, 0.66% water activity, 3.25 pH, 1.17 protein content,overall acceptability score of 6.56 and total color index of 45.94%.After the evaluation,it was found that the actual results were very close to the model estimates,indicating accurate model prediction.

Cataract is one of the most common ocular diseases caused by various causes including congenital, resulting from trauma, drug or radiation, diabetes, or aging. Diabetes type 2, as a common metabolic disorder, is one of the main reasons for cataracts. we aimed to study nutritional counseling's status on the correction of glucose and urea and creatinine patterns and blood pressure of patients undergoing cataract surgery and reducing the pre-operative hospitalization time.

In this study, 60 women with type 2 diabetes and 39 male participantsaged 25 to 65 (aged 25 to 65) were randomly assignedinto two groups (control without diet and nutritional counseling). The target group (presentation of diabetic diet and nutrition counseling) went under investigation two weeks before cataract surgery. Blood sampling proceeded from the arm vein in a sitting way one day before and afterthe diet (12 hours of fasting).

Fasting blood glucose, body weight, waist circumference, urea, creatinine, blood pressure, and hospitalization period were significantly decreased after surgery (p≤0.05).

The results showed that receiving nutrition counseling and diet before cataract surgery can improve fasting blood glucose, 2-hour blood glucose, body weight, urea, creatinine, blood pressure, and thus hospitalization and recovery be reduced after surgery.

Discovering the association between genetic variations of metabolizing enzymes with idiopathic diseases such as ulcerative colitis (UC) may not only be an auxiliary agent in diagnosis but also could be an effective pharmacotherapy for inflammatory bowel disease (IBD). The aim of the present case-control study was to determine the association of cytochrome P450 2D6 (CYP2D6 *4), N-acteyltransferase-2 (NAT2*7) and multidrug resistance 1 (MDR1) 3435 C/T genotypes with UC susceptibility and thiopurine methyltransferase (TPMT) enzyme activity. TPMT activity was measured by high performance liquid chromatography (HPLC) and genotypes for the 3 mentioned polymorphisms were determined in 215 unrelated UC patients and 212 unrelated healthy controls by polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP) in a Kurdish population from Iran. CYP2D6*4 A allele, NAT2*7 A and MDR1 3435 C/T alleles act synergistically to increase the risk of UC by 3.49 times. The frequency of the A allele of CYP2D6*4 was significantly higher in UC patients (12.6%) compared to control subjects (8.5%, P = 0.046) that significantly increased the risk of UC by 1.56-fold (P = 0.047). The frequencies of NAT2*7 genotypes and alleles were similar in both studied groups. The most important outcome of this study is that for the first time we demonstrated the simultaneous presence of TMDR1, A CYP2D6*4 and A NAT2*7 alleles robustly increased the risk of developing UC by 3.49-fold. The current study suggests that CYP2D6*4 and MDR1 3435 C/T gene polymorphisms may be risk factors for UC susceptibility.
