Abstract
Hepcidins, a group of antimicrobial peptides (AMPs), play a key role in the innate immune system of fishes and act against different pathogens. In this study, antimicrobial and immune-inflammatory activity of a synthetic EC-hepcidin1, previously identified from orange-spotted grouper, were evaluated. EC-hepcidin1 showed weak activity against the zoonotic fish pathogen Streptococcus iniae (MIC 100 μg mL-1 and MBC 150 μg mL-1). To study the effect of AMPs in general, and EC-hepcidin1 in particular, a primary cell culture (SC) from the fin tissue of the Caspian Trout (Salmo trutta caspius) was established. The neutral Red method on SC cells revealed that EC-hepcidin1 has no or very low cytotoxic properties. Treatment of cells with either EC-hepcidin1 (150 μg mL-1) or fish pathogen Streptococcus iniae (MOI = 10) and a mixture of both resulted in the up-regulation of gene expression of MHC-UBA, IL-6, and TNFα indicating the modulatory function on inflammatory processes. These findings indicate that EC-hepcidin1 might act as a candidate for modulation of the innate immune system in S. iniae-based infection.

Abstract
BACKGROUND Self-harm-related death is one of the most unfortunate, tragic, and regrettable types of death owing to injuries with a variety of socio-economic and cultural causes. The study aimed to determine the trend in the mortality of self-harm by sex and age at national and provincial levels in Iran over a period of 26 years. METHODS The Iran Death Registration System (DRS), cemetery databanks in Tehran and Esfahan, and the national population and housing censuses of Iran were used for this study. Using a growth model, the population was estimated in the age groups. Incompleteness, misalignment, and misclassification in the DRS were all considered and addressed accordingly. We used a spatio-temporal and Gaussian process regression model to estimate mortality rates in children and adults. RESULTS Over the study period, 67,670 deaths were estimated owing to self-harm across the country. The overall age-standardized mortality rate decreased from 4.32 per 100,000 (95% unit interface (UI): 3.25-5.75) to 2.78 (2.15-3.59) per 100,000 between 1990 and 2015, a reduction of approximately 35.65%. The M/F ratio was 2.03:1 with an annual percent change of -2.38% and -1.37% for women and men, respectively. The annual self-harm mortality rate was higher among individuals aged 15-24 years, as well as it was more in men during the study period. CONCLUSION Mortality from self-harm has declined over the study period in Iran. Higher rates in men and in population aged 15-24 years, with considerable variation by province, were the distinguishing features of self-harm. Iran needs to improve monitoring through a comprehensive multisectoral strategy; and most importantly, provide timely, effective and low-cost preventive interventions.

Abstract
OBJECTIVES Comprehensive and up-to-date data on fatal injury trends are critical to identify challenges and plan priority setting. This study provides a comprehensive assessment of poisoning mortality trends across Iran. STUDY DESIGN The data were gathered from various resources, including death registration systems, cemetery databases of Tehran and Esfahan, the Demographic and Health Survey of 2000, and three rounds of national population and housing censuses. METHODS After addressing incompleteness for child and adult death data separately and using a spatio-temporal model and Gaussian process regression, the level and trend of child and adult mortality were estimated. For estimating cause-specific mortality, the cause fraction was calculated and applied to the level and trend of death. RESULTS From 1990 to 2015, 40,586 deaths due to poisoning were estimated across the country. The poisoning-related age-standardized death rate per 100,000 was estimated to have changed from 3.08 (95% uncertainty interval [UI]: 2.32-4.11) in 1990 to 0.96 (95% UI: 0.73-1.25) in 2015, and the male/female ratio was 1.35 during 25 years of study with an annual percentage change of -5.4% and -4.0% for women and men, respectively. The annual mortality rate was higher among children younger than 5 years and the elderly population (≥70 years) in the study period. CONCLUSIONS This study showed that mortality from poisoning declined in Iran over the period from 1990 to 2015 and varied by province. Understanding the reasons for the differences of poisoning mortality by province will help in developing and implementing measures to reduce this burden in Iran.

Abstract
BACKGROUND A relatively young man (43 years old) was found to have a cataract after receiving prednisone before each of 35 neutrophil (PMN) donations over several years. Because corticosteroids are known to induce posterior subcapsular cataracts (PSCs), additional repeat PMN donors were examined ophthalmologically. STUDY DESIGN AND METHODS A controlled, blinded study was performed in 11 PMN donors who received prednisone with or without G-CSF before 17 to 46 leukapheresis donations over an average of 8.5 years. Control subjects were nine plateletpheresis donors of comparable age and donation experience, but they had never donated PMNs. A complete eye examination was performed by an ophthalmologist who was unaware of the donor's status (PMN vs. platelet). RESULTS Mild PSCs were found in 36 percent (4/11) of PMN donors versus 0 of 9 platelet donors (p = 0.068). Five of the 22 PMN donor eyes involved versus 0 of the 18 platelet donor eyes involved exhibited PSCs (p = 0.040). Cortical and nuclear cataracts were found similarly in both groups of donors (82% PMN vs. 56% platelet donors; p = 0.217); this indicated that lifestyle factors, independent of corticosteroids, that might predispose to cataract formation probably were comparable. CONCLUSION Corticosteroids given before PMN donations by leukapheresis might increase the risk of PSCs. Because of widespread renewed interest in PMN transfusions, this potential risk factor--if confirmed by studies of additional PMN donors--is of great international importance. Other centers are urged to perform ophthalmologic examinations on repeat PMN donors to clarify this issue.
