Abstract
Background and Aim: specific and scientific study in the field of malaria in Iran commenced simultaneouoly with establishing the Instituted of Malariology in Tehran University. Subsequently the Institute was changed to school of Public Health and Institute of Public Health. Research which this new situation resulted in increasing studies and researches in the field of malaria based on three main items as entomology and vector control, parasitology and epidemiology. Historical study of malaria prepares a worthy opportunity to remind the pioneers and those who dedicated their life for combating malaria. In this study the situation of published papers, prepared theses by Iranian researchers and specific training and fresher training courses in the filed of malaria parasitology during the last fifty years were considered.
Materials and Methods: This study was conducted as a retrospective study based on the collecting all available data from internal and external electronic sources, papers, books, reports, theses. Moreover, some interviews were made with relevant knowledgeable individuals, in the field of malaria parasitology in Iran.
Results: In this study 143 papers in the field of malaria parasitology were collected in Persian and English languages. Thirty five MSPH, MPH, PhD these and forty four specific courses were recorded as well.
Conclusion: The collected data indicating the correct comprehension of Iranian researchers from importance of malaria infection and its parasitology in Iran. The facts also show that specific training and retraining of malaria microscopy played considerable role in the control of malaria in Iran.

Abstract
Background and Aim: Availability of preliminary data on fauna and distribution of forensically important insects in a region is very important. Considering absence of such data in the north of Iran, this was study was undertaken with the aim of finding the fauna of insects on rabbit carcasses as an animal model in Babol, a city in the north of Iran.
Materials and Methods: This study was conducted in three areas, that is, urban, semi-urban and rural, in summer and autumn in 2014. Using Schoenly traps, samples were collected once daily until the decomposition of the rabbit carcasses was complete.
Results: A total of 1978 adult flies from 17 species were identified. The main fly families included Calliphoridae, Sarcophagidae, Muscidae and Fanniidae. On the whole, the families with the highest and lowest numbers were Muscidae and Phoridae, respectively. Some families of minor medical importance, such as Anthomyiidae, Sepsidae, Phoridae and Stratiomyidae, were collected in small numbers. The Sarcophaga melanura was introduced in Iran for the first time.
Conclusion: The main finding of this study is identification of some of the most important flies and other anthropoda, which can be very helpful and useful in forensic investigations – finding time and place of death. Classification of the data on species based on their ecosystems is another important finding emphasized in this study, something of practical importance in scene of crime investigations.

Abstract
Background and Aims: Ticks are external parasites that can be vectors of several disease agents. This survey was carried out to determine distribution and biological diversity of hard tick species in Maraveh Tapeh County, Golestan Province, Iran in spring 2016.
Materials and methods: In 10 selected villages in the study area, about 29 cattle, 99 sheep, 62 goats and 11 camels were inspected for tick infestation. The ticks isolated were preserved in a solution of 70% alcohol and identified. The Margalef, Shannon-Wiener, Simpson and Evenness indices were used to measure the biodiversity.
Results: A total of 476 ticks were collected. Two hard tick genera (Hyalomma and Rhipicephalus) and twelve species were identified including Hyalomma anatolicum, Hy. scupense, Hy. aegyptium, Hy. marginatum, Hy. dromedarii, Hy. rufipes, Hy. asiaticum, Hy. excavatum, Hy. detritum, Rhipicephalus turanicus, R. bursa and R. sanguineus. Further analysis of the data showed that R. sanguineus and Hy. asiaticum were the most abundant species in the whole area and plateau areas, respectively, while R. sanguineus was most abundant in both hillside and mountainous areas. Based on the Margalef index, the species diversity was higher in foothill areas and it was lower in the goat host than other hosts, while based on the Shannon-Wiener index, the species diversity was higher in plateau areas and in the sheep host it was less than in other hosts.
Conclusion: Ticks population dynamic studies and calculating their biodiversity indices are helpful in understanding the situation of vectors and the future situation of vector-borne diseases.

Abstract
Background and Aim: The Trabecular Bone Score (TBS) is a novel tool for assessing bone microarchitecture and identifying individuals at risk for osteoporotic fractures. This study aimed to evaluate the association between Single Nucleotide Polymorphisms (SNPs) of the SOST gene and TBS in Iranian postmenopausal women.
Materials and Methods: This study included 1/071 postmenopausal women from the Bushehr Elderly Health (BEH) Cohort study. Relationship between Seven independent SNPs in the SOST gene located on chromosome 17q21.31 were investigated with TBS L1–L4. Associations were tested using generalized linear models under additive, dominant, and recessive genetic models. A genetic score was also calculated by summing the weighted number of risk alleles based on the regression coefficients of the SNPs.
Results: After adjustment for age and Body Mass Index (BMI), SNP rs2023794-C showed a statistically significant association with TBS in the additive model (β = 0/ 03, P = 4/7×10⁻⁵, PFDR = 0/0003) and the dominant model (β = 0/033, P = 2/5×10⁻⁵, PFDR = 0/0003). Furthermore, higher genetic scores were positively associated with increased TBS values.
Conclusion: Our findings highlight the potential role of SOST gene variants and derived genetic score in predicting bone quality in postmenopausal women. These genes could aid in identifying individuals at higher risk of poor bone quality and in developing personalized osteoporosis prevention strategies.
