Background: Findings of epidemiologic studies on the relationship between fruit and vegetable consumption and prostate cancer (PCa) risk have been inconclusive. We therefore examined the association between intake of fruits and vegetables and PCa risk in Iran. Materials and Methods: In this hospital based, case-control study, a total of 50 patients with PCa and 100 controls underwent face-to-face interviews. Regression analysis was used to examine the relation between fruit and vegetable intake and PCa risk. Results: A protective independent effect was observed for the highest tertile of total fruit and vegetable (OR: 0.33, CI: 0.04-0.30, p value<0.001), total fruit (OR: 0.30, CI: 0.06-0.4, p value=0.03) and total vegetable (OR: 0.31, CI: 0.02-0.21, p value<0.001) consumption. Within the group of fruits, a significant inverse association was observed for apple and pomegranate (p trends were 0.01 and 0.016, respectively). In the vegetable group, a significant inverse association was observed for tomatoes (p trend<0.001) and cabbage (p trend=0.021). Conclusions: The results of the present study suggested that fruits and vegetable intake might be negatively associated with PCa risk.

Background: Prostate cancer is the most frequently occurring cancer among males in economically developed countries. Among the several risk factors that have been suggested, only age, ethnicity, diabetes, and family history of prostate cancer are well-established and primary prevention of this disease is limited. Prior studies had shown that dietary intake could be modified to reduce cancer risk. We conducted a hospital-based, casecontrol study to examine the association between dietary patterns and prostate cancer risk in Iran. Materials and Methods: A total of fifty patients with prostate cancer and a hundred controls underwent face-to-face interviews. Factor analysis was used to determine the dietary patterns. Multivariate logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Results: We defined two major dietary patterns in this population: 'western diet'(high in sweets and desserts, organ meat, snacks, tea and coffee, French fries, salt, carbonated drinks, red or processed meat) and 'healthy diet' (high in legumes, fish, dairy products, fruits and fruit juice, vegetables, boiled potatoes, whole cereal and egg). Both Healthy and western pattern scores were divided into two categories (based on medians). Higher scores on Healthy pattern was marginally significantly related to decreased risk of prostate cancer (above median vs below median, OR =0.4, 95%CI=0.2-1.0). An increased risk of prostate cancer was observed with the higher scores on the Western pattern (above median vs below median, OR=4.0, 95%CI=1.5-11.0). Conclusions: The results of this study suggested that diet might be associated with prostate cancer among Iranian males.

A general nonlinear system can be identified as a piecewise affine system by approximating a nonlinear function using a piecewise affine one with arbitrary accuracy. In this paper, the problem of identifying discrete-time hybrid systems in the piecewise affine form where the discrete state depends on continuous state with a hysteresis function is addressed. The first step of the proposed identification method is the estimation of the local parameter vectors for small neighborhood of each measured data point. Then the local parameter vectors are clustered. Finally, the threshold levels of the hysteresis function which defines the discrete state are estimated.

A single chamber microbial electrolysis cell (MEC) was constructed to treat olive oil mill wastewater(OOMW) biologically and produce hydrogen simultaneously. To characterize the optimal MEC condition, the MECwas fed with synthetic wastewater (SW) having a phenol concentration of 250mg l1. Therefore, the influence of differentapplied voltages and cathode materials was explored and the optimum condition for MEC was determined, whichwas when the stainless steel cathode was implemented and the external voltage of 0.6 V was supplied. Chemical oxygendemand (COD) removal of 62% and current density of 362 mA m2 were obtained for OOMW treatment, whileCOD removal of 73% and the current density of 274.4mA m2 were attained for SW treatment in this MEC at 0.6 V. Hydrogen production rate was 0.045m3 H2 m3d1 for SW and 0.053m3 H2 m3d1 for OOMW. Furthermore, the coulombicefficiency and cathodic hydrogen recovery were 23% and 81%, respectively. Finally, MEC performance in termsof electrical current generation, wastewater treatment and hydrogen production was compared to some similar reportedstudies.

In this study, rheological and thermal decomposition behavior of AISI 4605 MIM feedstock investigated using capillaryand thermogravimetric analysis. For this purpose and in order to find the critical solids loading, the feedstock was preparedby compounding AISI 4605 micro powder (~ 4 μm) with an adopted multi-component wax-based binder system at variouspowder loadings (53–61 vol%). After preparing the feedstock with optimal solids loading, fundamental rheological characteristicsof homogenized feedstock, including flow behavior index (n), flow activation energy (E), and general moldabilityindex (αstv) were studied. Furthermore, thermal analysis of feedstock, including apparent debinding activation energy andmaster decomposition curve was investigated. The results showed that critical solids loading of feedstock is around 58 vol%. The flow behavior index of developed feedstock was acceptable, since it came out to be less than one. Also, flow activationenergy which shows the sensitivity of material to temperature changes, came out to be 70.406 kJ/mol. Using these two parameters,general moldability index was calculated to be 2.3147E−06. Finally, the master decomposition curve of feedstock wasconstructed based on calculated apparent debinding activation energy and verified using decomposition curves at differentheating rates of 2, 5 and 10 °C/min.
Semi-active control of smart building-MR damper systems using novel TSK-Inv and max-min algorithms

Two novel semi-active control methods for a seismically excited nonlinear benchmark building equipped with magnetorheological dampers are presented and evaluated in this paper. While a primary controller is designed to estimate the optimal control force of a magnetorheological (MR) damper, the required voltage input for the damper to produce such desired control force is achieved using two different methods. The first technique uses an optimal compact Takagi-Sugeno-Kang (TSK) fuzzy inverse model of MR damper to predict the required voltage to actuate the MR dampers (TSKFInv). The other voltage regulator introduced here works based on the maximum and minimum capacities of MR damper at each time-step (MaxMin). Both semi-active algorithms developed here, use acceleration feedback only. The results demonstrate that both TSKFInv and MaxMin algorithms are quite effective in seismic response reduction for wide range of motions from moderate to severe seismic events, compared with the passive systems and performs better than original and Modified clipped optimal controller systems, known as COC and MCOC.

Background: Migraine headaches have been associated with sensory hyperactivity and anomalies in social/emotional responses. The main objective of this study was to evaluate the potential involvement of orexin 1 receptors (Orx1R) within the basolateral amygdala (BLA) in the modulation of pain and psychosocial dysfunction in a nitroglycerin (NTG)-induced rat model of migraine. Methods: Adult male Wistar rats were injected with NTG (5 mg/kg, intraperitoneal) every second day over nine days to induce migraine. The experiments were done in the following six groups (6 rats per group): untreated control, NTG, NTG plus vehicle, and NTG groups that were post-treated with intra-BLA microinjection of Orx1R antagonist SB-334867 (10, 20, and 40 nM). Thermal hyperalgesia was assessed using the hot plate and tail-flick tests. Moreover, the elevated plus maze (EPM) and open field (OF) tests were used to assess anxiety-like behaviors. The animals’ sociability was evaluated using the three-chamber social task. The NTG-induced photophobia was assessed using a light-dark box. Results: We observed no change in NTG-induced thermal hyperalgesia following administration of SB-334867 (10, 20, and 40 nM). However, SB-334867 (20 and 40 nM) aggravated the NTG-induced anxiogenic responses in both the EPM and OF tasks. The NTG-induced social impairment was overpowered by SB-334867 at all doses. Time spent in the dark chamber of light-dark box was significantly increased in rats treated with SB-334867 (20 and 40 nM/rat). Conclusions: The findings suggest a role for Orx1R within the BLA in control comorbid affective complaints with migraine in rats.
