Purpose: Toxoplasma gondii is an opportunistic parasite infecting all warm-blooded animals including humans. The dense granule antigens (GRAs) play an important role in parasite survival and virulence and in forming the parasitophorous vacuole. Identification of protein characteristics increases our knowledge about them and leads to develop the vaccine and diagnostic studies. Materials and Methods: This paper gave a comprehensive definition of the important aspects of GRA12 protein, including physico-chemical features, a transmembrane domain, subcellular position, secondary and tertiary structure, potential epitopes of B-cells and T-cells, and other important features of this protein using different and reliable bioinformatics methods to determine potential epitopes for designing of a high-efficient vaccine. Results: The findings showed that GRA12 protein had 53 potential post-translational modification sites. Also, only one transmembrane domain was recognized for this protein. The secondary structure of GRA12 protein comprises 35.55% alpha-helix, 19.50% extended strand, and 44.95% random coil. Moreover, several potential B- and T-cell epitopes were identified for GRA12. Based on the results of the Ramachandran plot, 79.26% of amino acid residues were located in favored, 11.85% in allowed and 8.89% in outlier regions. Furthermore, the results of the antigenicity and allergenicity assessment noted that GRA12 is immunogenic and nonallergenic. Conclusion This research provided important basic and conceptual data on GRA12 to develop an effective vaccine against acute and chronic toxoplasmosis for further in vivo investigations. More studies are required on vaccine development using the GRA12 alone or combined with other antigens in the future.

Purpose: Toxoplasmosis, transmitted by Toxoplasma gondii, is a worldwide parasitic disease that affects approximately one-third of the world’s inhabitants. Today, there are no appropriate drugs to deter tissue cysts from developing in infected hosts. So, developing an effective vaccine would be valuable to avoid from toxoplasmosis. Considering the role of microneme antigens such as microneme protein 4 (MIC4) in T. gondii pathogenesis, it can be used as potential candidates for vaccine against T. gondii. Materials and Methods: In this study several bioinformatics methods were used to assess the different aspects of MIC4 protein such as secondary and tertiary structure, physicochemical characteristics, the transmembrane domains, subcellular localization, B-cell, helper-T lymphocyte, cytotoxic-T lymphocyte epitopes, and other notable characteristic of this protein design a suitable vaccine against T. gondii. Results: The studies revealed that MIC4 protein includes 59 potential post-translational modification sites without any transmembrane domains. Moreover, several probable epitopes of Band T-cells were detected for MIC4. The secondary structure comprised 55.69% random coil, 5.86% beta-turn, 19.31% extended strand, and 19.14% alpha helix. According to the Ramachandran plot results, 87.42% of the amino acid residues were located in the favored, 9.44% in allowed, and 3.14% in outlier regions. The protein allergenicity and antigenicity revealed that it was non-allergenic and antigenic. Conclusion This study gives vital basic on MIC4 protein for further research and also established an effective vaccine with different techniques against acute and chronic toxoplasmosis.

Objective: Hypovitaminosis D3 is a significant concern among pregnant women and their newborns because vitamin D3 (Vit-D3) plays a crucial role in embryonic growth, development, and health. This study aimed to evaluate the Vit-D3 status of a group of pregnant Iranian women and its association with newborn Vit-D3 levels, medical and clinical indices after delivery. Methods: A total of 206 pregnant women and their newborns were assessed for Vit-D3 levels and their correlation with gestational age. Mean±standard deviation (SD) or the orders (non-parametric tests) of variables were compared, and correlation estimations were performed to elucidate any differences or associations between groups, with a confidence interval of at least 0.95. Results: The mean±SD of mothers’ age and gestational age were 29.65±6.18 years and 35.59±1.6 weeks, respectively. Neonatal Vit-D3 levels were associated with maternal age. Using a 30 ng/mL cutoff point for serum Vit-D3 levels, 83.5% of pregnant women and 84.7% of newborns had hypovitaminosis D3. The average Vit-D3 levels of mothers and newborns at delivery time were 23.5±8.07 ng/mL and 20.76±9.14 ng/mL, respectively. Newborn Vit-D3 levels were positively correlated with maternal Vit-D3 serum levels (R=0.744; P<0.001) and gestational age (R=0.161; P=0.022). In newborns, head circumference was inversely correlated with bilirubin level (R=-0.302; P<0.001) but directly associated with weight (R=0.640; P<0.001). Conclusion Hypovitaminosis D3 remains a significant challenge for pregnant Iranian women. Maternal Vit-D3 levels provide for the newborn’s needs, particularly in the late stages of pregnancy. Therefore, Vit-D3 supplementation and regular monitoring are essential for pregnant women and their newborns.

BACKGROUND: Self-care of diabetes is an essential part for controlling the disease and improvement of quality of life in type 2 diabetes mellitus (T2DM) patients. This study aimed to analyze the associated factors of quality of life in patients with T2DM in order to design effective interventions. METHODS: This cross-sectional study was conducted on 120 T2DM patients referred to health centers of Chaldoran, West Azerbaijan Province, Iran. The quality of life's questionnaires from World Health Organization and the self-care behaviors' questionnaires were used for data collection. RESULTS: The mean age of patients was 46.30% and 53.30% of them were male. Among demographic variables, gender (P=0.002), age groups (P=0.007), and household monthly income (P=0.009) were significantly associated with total quality of life. Also, self-care nutrition (odds ratio [OR], 1.47; P=0.001), self-management of blood glucose control (OR, 1.29; P=0.002), and self-medication behavior (OR, 1.18; P=0.030) were identified as factors significantly associated with quality of life. CONCLUSION: Self-care behaviors were significantly associated with quality of life; among them, the greatest influence was observed in self-care nutrition behavior. According to the findings of this study, appropriate interventions on self-care behaviors about nutrition can improve the quality of life for T2DM patients.

Objective To examine the prevalence and clinical manifestations of cutaneous leishmaniasis (CL) in Iran. Methods This study was conducted in Iran between 2011 and 2013. Sampling, preparing, developing, and fixing of suspicious skin lesions were completed in healthcare centers in 31 Iranian provinces as well as in the Academic Reference Laboratory and the National Reference Laboratory. The information was then analyzed at the Ministry of Health's Information Management Center of Contagious Diseases. Results Over a three-year period, the number of people identified with CL was 56 546. The highest incidence was reported in 2011 (27.5 per 100 000). Wet CL accounted for 43.7% of cases while 43.3% resulted from sporotrichoid leishmaniasis. The results showed that there was a higher incidence of CL due to Leishmania major (50.2%) than to Leishmania tropica. The results of this study found that the highest incidence of CL had happened respectively in Ilam, Fars and, Khorasan Razavi Provinces between 2011 and 2013. Conclusions Although the incidence of the disease is declining, CL is still a public health concern and disease control protocols need to be established. Therefore, further studies are needed to identify the vectors, reservoirs, and disease species as well as to develop appropriate disease control strategies.

Objectives To aim to determine the status and epidemiological aspects of malaria in Iran in favour of gaining a better understanding of the national control of malaria. Methods This epidemiological study examined the status of malaria from 2011 to 2014 in Iran. Data were collected from the Ministry of Health's protocol for controlling and eliminating malaria, which is currently in use. This malaria information reporting system is automated in all Iranian provinces and cities, and all information is submitted online to the center for communicable disease control in the Ministry of Health. Information about malaria is available for researchers to evaluate. Results The incidence rates decreased from 2011 to 2014. There were 4.76, 2.12, 1.80, and 1.59 per 100 000 people, respectively from 2011 to 2014. During the four-year period (2011–2014), the highest numbers of cases occurred in those aged 16–25 years, by age, and in men, by sex. Most of the cases were workers and located in rural areas. An average 52.58% of cases were Iranian. The highest incidence rates from 2011 to 2014 were located in Sistan and Baluchestan province. There were 89.94, 43.9, 38.3, and 30.66 per 100 000 people. The highest numbers of malaria cases were recorded in the cities Sarbaz, Nickshahr, and Chabahar in Sistan and Baluchestan province and Bandar Abbas, Bandar Jask, and Bandar Lengeh in Hormozgan province. During the four-year period, 57.05% of cases were caused by imported factors. The majority of cases were related to the trophozoite lifecycle of parasites. Regarding surveillance, there was inactive care in the majority of cases. Vivax malaria was the most prevalent. Conclusions Despite the recently declining trend in reported cases, the expansion of local transmission, especially in areas with cross-border travel, is very worrying. Improved malaria control interventions can be effective for elimination of malaria in Iran; these can include programs to control border travel and focused interventions for high incidence areas and high-risk groups such as rural residents, men, workers, and people <35 years old.
