ABSTRACT During recent decades, different formulas have been developed to estimate longshore sediment transport rates through calibration using a wide variety of datasets, applicable for a range of particular wave and beach conditions. The equations that have shown the best capability to predict Bulk Longshore Sediment Transport Rate (BLSTR) are the formulas derived by CERC and by Kamphuis. In the present study, the five process parameters as used in the Kamphuis formula are accepted. The CERC formula includes only two of the five process parameters used in Kamphuis’ formula. A renewed optimization to derive the power of the five Kamphuis’ process parameters using an extensive dataset by Bayram was performed by Mil-Homens. In addition to this valuable effort, our contribution introduces two innovations. Firstly, the power coefficients of the five Kamphuis process parameters are optimized using a broad range of meta-heuristic algorithms. Secondly, the optimization is not based on the Bayram dataset as carefully collected and reviewed from published manuscripts but on a methodologically more homogeneous Iranian dataset acquired for port design and port management purposes. Independently from the results by Mil-Homens derived from the Bayram dataset, our study confirms these findings based on a totally different dataset. Specifically, the weaker impact of wave period and the stronger impact of the median grain diameter are in accordance with each other. The latter finding provides a stronger support for the mutual cancellation of the impact of slope and grain diameter in BLSTR, lending explanatory support to the CERC formula once beach slope and grain size are not known.

SUMMARY: Honey is a natural antioxidant that its protective effects have been proven against ischemia-reperfusion (IR) injury. The aim of this study was to evaluate the ameliorative effect of Persian Honey, Apis mellifera meda skorikov, on gastrocnemius muscle IR injury. Eighty adult male Sprague-Dawley rats weighing 250-300 g were used. They were divided into ten groups (N=8 per group). The ischemia was conducted with a silk suture 6-0 using the slipknot technique. All groups were rendered in ischemic for 3 h, and reperfused for various times of 3 days (3-day reperfusion), 7 days (7-day reperfusion), 14 days (14-day reperfusion), and 28 days (28-day reperfusion). Half of the groups had experimental honey (5 %) treatment immediately after ischemia. After reperfusion, the rats, based on the grouping, were killed with high doses of anesthetic, and the gastrocnemius muscles were removed and fixed. After the tissue processing, the evaluation of edema and mast cells infiltration was performed with hematoxylin-eosin and toluidine blue staining, respectively. TNF-α was detected with immunohistochemistry method. The amount of TNF-α as an index of acute inflammatory except the 3rd day significantly decreased on the other day of reperfusion (7th, 147th and 287th days). The mast cells infiltration was significantly decreased on 77th and 147th days. The tissue edema was decreased significantly in honey administrated group in the comparison with placebo groups. Honey administration can reduce damage caused by ischemia-reperfusion in the rat gastrocnemius muscle.

RESUMEN: La miel es un antioxidante natural; sus efectos protectores han sido probados contra la lesión por isquemiareperfusión (IR). El objetivo de este estudio fue evaluar el efecto de mejora de la miel persa Apis mellifera meda skorikov, en la lesión por IR del músculo gastrocnemio. Se utilizaron 80 ratas Sprague-Dawley macho adultas con un peso entre 250 y 300 g divididas en diez grupos (N = 8 por grupo). La isquemia se realizó con una sutura de seda 6-0 utilizando la técnica slipknot permaneciendo isquémicos durante 3 h. La reperfusión se realizó durante varios tiempos de 3 días, 7 días (reperfusión de 7 días), 14 días (reperfusión de 14 días) y 28 días (28 días reperfusión). La mitad de los grupos recibió tratamiento experimental con miel (5 %) inmediatamente después de la isquemia. Después de la reperfusión, las ratas, fueron sacrificadas con altas dosis de anestésico, y los músculos gastrocnemios fueron removidos y fijados. Después de procesar el tejido, se realizó la evaluación del edema y la infiltración de mastocitos se realizó con tinción de hematoxilina-eosina y azul de toluidina, respectivamente. TNF-α se detectó con el método de inmunohistoquímica. La cantidad de TNF-α como índice de inflamación inflamatoria aguda, excepto en el tercer día, disminuyó significativamente al día siguiente de la reperfusión (7, 14 y 28 días). La infiltración de mastocitos disminuyó significativamente a los 7 y 14 días. El edema tisular disminuyó significativamente en el grupo administrado con miel en comparación con los grupos placebo. El tratamiento con miel puede reducir el daño causado por la isquemia-reperfusión en el músculo gastrocnemio de la rata.

Abstract Background: Cardiovascular disease is a major health concern around the world. Objective: To assess the outcomes and feasibility of a pharmacy-based cardiovascular screening in an urban referral community pharmacy in Iran. Methods: A cross sectional study was conducted in a referral community pharmacy. Subjects aged between 30-75 years without previous diagnose of cardiovascular disease or diabetes were screened. Measurement of all major cardiovascular risk factors, exercise habits, medical conditions, medications, and family history were investigated. Framingham risk score was calculated and high risk individuals were given a clinical summary sheet signed by a clinical pharmacist and were encouraged to follow up with their physician. Subjects were contacted one month after the recruitment period and their adherence to the follow up recommendation was recorded. Results: Data from 287 participants were analyzed and 146 were referred due to at least one abnormal laboratory test. The results showed 26 patients with cardiovascular disease risk greater than 20%, 32 high systolic blood pressure, 22 high diastolic blood pressures, 50 high total cholesterol levels, 108 low HDL-C levels, and 22 abnormal blood glucose levels. Approximately half of the individuals who received a follow up recommendation had made an appointment with their physician. Overall, 15.9% of the individuals received medications and 15.9% received appropriate advice for risk factor modification. Moreover, 7.5% were under evaluation by a physician. Conclusion: A screening program in a community pharmacy has the potential to identify patients with elevated cardiovascular risk factor. A plan for increased patient adherence to follow up recommendations is required.
