Background: Current study was designed to provide a better insight into the circulating genotypes, genetic diversity, and population structure of spp. between southeast of Iran and Pakistan
Methods: From Jun 2020 to Dec 2020, 46 hydatid cysts were taken from human (n: 6), camel (n: 10), goat (n: 10), cattle (n: 10) and sheep (n: 10) in various cities of Sistan and Baluchestan Province of Iran, located at the neighborhood of Pakistan. DNA samples were extracted, amplified, and subjected to sequence analysis of and genes.
Results: The phylogeny inferred by the Maximum Likelihood algorithm indicated that G1 genotype (n: 19), G3 genotype (n: 14) and G6 genotype (n: 13) assigned into their specific clades. The diversity indices showed a moderate (: Hd: 0.485) to high haplotype diversity ( Hd: 0.867) of s.s. (G1/G3) and low nucleotide diversity. The negative value of Tajima's and Fu's Fs test displayed deviation from neutrality indicating a recent population expansion. A parsimonious network of the haplotypes of displayed star-like features in the overall population containing IR9/PAK1/G1, IR2/PAK2/G3 and IR18/G6 as the most common haplotypes. A pairwise fixation index (st) indicated that s.s. populations are genetically moderate differentiated between southeast of Iran and Pakistan. The extension of haplotypes PAK18/G1 (sheep) and PAK26/G1 (cattle) toward Iranian haplogroup revealed that there is dawn of flow due to a transfer of alleles between mentioned populations through transport of livestock or their domestication.
Conclusion: The current findings strengthen our knowledge concerning the evolutionary paradigms of in southeastern borders of Iran and is effective in controlling of hydatidosis.

Life satisfaction around the world: Measurement invariance of the Satisfaction With Life Scale (SWLS) across 65 nations, 40 languages, gender identities, and age groups.

The Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset-with data collected between 2020 and 2022 -to assess measurement invariance of the SWLS across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). All participants completed the SWLS under largely uniform conditions.

Background: Drowning is a serious and neglected public health threat, and prevention of drowning has a multisectoral nature and requires multidimensional research. Therefore, this study aimed to evaluate the spatio-temporal variation in fatal unintentional drowning rates among the Iranian population from 2005 to 2022.
Methods: In this repeated cross-sectional study, registry data were extracted from legal medicine organisations during 2005-2022.

is a parasite prevalent in the temperate regions of the vast Palearctic realm, including Iran. In this study, we investigated infection in road-killed animals and carcasses in northern and northeastern Iran by artificial digestion. We assessed species identification and intraspecific genetic diversity using the markers 5S ribosomal DNA intergenic spacer (5S rDNA), internal transcribed spacer I (ITS1), and cytochrome oxidase subunit I ().

Background: The Anopheles culicifacies complex is one of the most important malaria vectors in Southeast Asia and Southeastern Iran. Although the sibling species within this complex are morphologically indistinguishable, they differ significantly in their disease transmission potential, blood-feeding behaviour, and other biological traits. Cytogenetic and chromosomal studies have identified five sibling species within this complex: A, B, C, D, and E.
