Antidepressant-like effect of essential oil of Lavandula angustifolia Mill and Citrus bigaradia Duh with forced swimming test in reserpinized mice Balb/C.

Background: Levandula angustifolia and Citrus aurantium essential oils possess phenolic compounds and in Iranian traditional medicine are commonly used as sedative. The aim of this study was to evaluate the antidepressant activities of Levandula angustifolia and Citrus bigaradia in adult reserpinized mice. Methods: In this experimental study, mice were divided into 10 groups of 8 mice each, including: Group 1, control group received normal saline. Group 2, was treated reserpine (5 mg/kg, IP). Group 3, 4, 5 and 6 were treated with reserpine (5 mg/kg, IP) and four Citrus aurantium different doses (25, 50, 100, 200 mg/kg). Group 7, 8 and 9 were treated with reserpine (5 mg/kg, IP) and three Levandula angustifolia doses (25, 50, 100 mg/kg). Group 10 was treated with reserpine (5 mg/kg, IP) and imipramine (15 mg/kg). In all groups the forced swimming test was done and the level of malondialdehyde (MDA) in brain tissue was measured to estimate the oxidative stress status. Data were analyzed by one-way ANOVA and Tukey post hoc test. Results: Levandula angustifolia, Citrus aurantium and imipramine in reserpinized mice caused the mice to spend less time in the forced swimming test, compared to the control group (p<0.01). Also Citrus aurantium with dose of 50 and 100 mg/kg and Lavandula angustifolia with dose of 25 and 50 mg/kg in reserpinized mice reduced immobility time and levels of MDA compared the control group (p<0.01). Conclusion: Lavander and Citrus aurantium essential oils have considerable antidepressant activity which might be attributed to their antioxidant effects

The Moral Advice of ‘Minooye Kherad’ and its Effect on Ferdowsi’s Shahnameh

‘Minooye Kherad’ is one of the most significant letters of advice in the Middle Persian Period and the Pahlavi literature, including the books of Behdinan. This rather short book is full of the wise and beautiful religious and practical advice in diverse fields. Shahnameh, the master piece of Ferdowsi is the essence and protector of the ancient Persian culture. The research focuses on whether the book ‘Minooye Kherad’ has influenced the contents of Shahnameh or not. It also studies whether Ferdowsi has been inspired by this book or not. The descriptive-analytic methodology is based on studying the books, articles and analyzing different data. The result of this research indicated that Shahnameh has been influenced by this short book in the concepts related to moral advice. The great role of wisdom in Shahnameh emerges from the culture of Ancient Persia. And the book ‘Minooye Kherad’ has had a significant role in transferring this valuable characteristic. Ferdowsi is not the creator of these moral concepts, but he has added to the richness of these moral concepts by the help of his literal and artistic talents and has offered them to his audiences in his Masterpiece‘Shahnameh’

Molecular Genotyping of the Human Cystic Echinococcosis in Mazandaran Province, North of Iran

Background: The larval stage of the tapeworm (cestode) Echinococcus granulosus is the etiological agent of hydatidosis or cystic echinococcosis, which is the zoonotic parasitic disease causing morbidity and mortality in both humans and livestock. Due to a lack of accurate data on the human isolates of E. granulosus in Mazandaran Province, northern Iran, the current study aimed to survey the population genetic pattern of cystic echinococcosis isolated from humans by sequencing the mitochondrial genes of NADH dehydrogenase subunit 1 (nad1). Methods: Overall, 47 formalin fixed paraffin-embedded tissue (FFPT) blocks were collected from patients' files in various pathology departments of Mazandaran Province in Iran from 2003 to 2015. PCR was performed to amplify a 398bp DNA fragment of mitochondrial nad1. PCR products were sequenced by Bioneer Corporation (South Korea), and the resulting data were analyzed via relevant software to determine the genotypes. Results: The nad1 gene was successfully amplified on 10 from all of the E. granulosus isolates. Overall, 66.6% and 33.3% of the isolates in the studied area displayed the G1 and G2-G3 genotypes, respectively. Conclusion: This study may provide the foundation for further studies in revealing the regional transmission patterns and also in designing adequate control procedures

Phylogeography, Genetic Diversity and Population Structure of Echinococcus granulosus Sensu Stricto Inferred by Mitochondrial DNA Markers between Southeast of Iran and Pakistan

Background: Current study was designed to provide a better insight into the circulating genotypes, genetic diversity, and population structure of Echinococcus 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 cox1 and nad1 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 (nad1: Hd: 0.485) to high hap- lotype diversity (cox1: Hd: 0.867) of E. granulosus s.s. (G1/G3) and low nucleotide diver- sity. The negative value of Tajima’s D and Fu’s Fs test displayed deviation from neutrali- ty indicating a recent population expansion. A parsimonious network of the haplotypes of cox1 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 (Fst) indicated that E. granulosus s.s. populations are genetically moderate differen- tiated 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 Echinococcus 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 evolution- ary paradigms of E. granulosus in southeastern borders of Iran and is effective in control- ling of hydatidosis

Carnivores as Important Reservoirs of Intestinal Helminthic Infections in Mazandaran Province, Northern Iran

Background: Intestinal parasites are the most common causes of gastrointestinal disease in canine. Stray dogs and wild candies can represent potential reservoirs of enteropathogens to other hosts. Therefore, present study determined the prevalence of intestinal parasites in canine in Mazandaran Province, northern, Iran. Methods: Overall, 58 small intestinal samples of animals (42 stray dogs and 16 jackals) were collected from Oct 2012 to Dec 2013. The intestine contents were studied to detect and identify helminth infections. Then, the helminths were collected and their morphological traits were identified. Results: Overall among infected stray dogs and jackals, 11 species were found. Three species of nematodes, seven species of cestodes and one trematode were observed. The prevalence of gastrointestinal helminths of stray dogs and jackals were 59.5% and 50%, respectively. Among registered zoonotic helminths A. caninum was the predominant parasite both stray dogs and jackals. Interestingly, Spirometra spp. was reported in these animals. Moreover, A. caninum showed a higher percentage rate in center region of province. Conclusion: There are the clear risks of zoonotic helminths parasites infection in this region. Therefore, understanding the epidemiology of zoonotic parasite infection is useful for health care access both domestic animals and humans health

Aetiology of livestock fetal mortality in Mazandaran province, Iran

In the farming industry, the productivity of livestock herds depends on the fertility efficiency of animals. The accurate diagnosis of a broad range of aetiological agents causing fetal death is often difficult. Our aim was to assess the prevalence rates of Toxoplasma gondii, Neospora caninum, and Brucella spp. infections in ruminant abortion using bacteriological culture and molecular techniques in Mazandaran Province, northern Iran. Samples were collected from 70 aborted sheep, goat, and cattle fetuses between September 2014 and December 2015. Necropsy was performed on all the received samples, and brain tissue and abomasal content were obtained from the aborted fetuses. Protozoan infections were detected by specific polymerase chain reaction (PCR) and bacterial agents using bacteriological examinations and PCR assay. Infectious pathogens were detected in 22 out of 70 (31.4%) examined fetuses. Moreover, T. gondii, N. caninum, and B. melitensis were verified in 13 (18.6%), four (5.7%), and two (2.85%) samples, respectively. Our results showed that infection with the mentioned pathogenic agents may lead to fetal mortality, which can be a major cause of economic loss. The listed pathogens could be considered important etiological agents of fetal loss in Mazandaran Province, for which appropriate control measures such as vaccination and biosecurity can be implemented to prevent infection and reduce reproductive loss in livestock farms

The global burden of adolescent and young adult cancer in 2019 : a systematic analysis for the Global Burden of Disease Study 2019

Background In estimating the global burden of cancer, adolescents and young adults with cancer are often overlooked, despite being a distinct subgroup with unique epidemiology, clinical care needs, and societal impact. Comprehensive estimates of the global cancer burden in adolescents and young adults (aged 15-39 years) are lacking. To address this gap, we analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, with a focus on the outcome of disability-adjusted life-years (DALYs), to inform global cancer control measures in adolescents and young adults. Methods Using the GBD 2019 methodology, international mortality data were collected from vital registration systems, verbal autopsies, and population-based cancer registry inputs modelled with mortality-to-incidence ratios (MIRs). Incidence was computed with mortality estimates and corresponding MIRs. Prevalence estimates were calculated using modelled survival and multiplied by disability weights to obtain years lived with disability (YLDs). Years of life lost (YLLs) were calculated as age-specific cancer deaths multiplied by the standard life expectancy at the age of death. The main outcome was DALYs (the sum of YLLs and YLDs). Estimates were presented globally and by Socio-demographic Index (SDI) quintiles (countries ranked and divided into five equal SDI groups), and all estimates were presented with corresponding 95% uncertainty intervals (UIs). For this analysis, we used the age range of 15-39 years to define adolescents and young adults. Findings There were 1.19 million (95% UI 1.11-1.28) incident cancer cases and 396 000 (370 000-425 000) deaths due to cancer among people aged 15-39 years worldwide in 2019. The highest age-standardised incidence rates occurred in high SDI (59.6 [54.5-65.7] per 100 000 person-years) and high-middle SDI countries (53.2 [48.8-57.9] per 100 000 person-years), while the highest age-standardised mortality rates were in low-middle SDI (14.2 [12.9-15.6] per 100 000 person-years) and middle SDI (13.6 [12.6-14.8] per 100 000 person-years) countries. In 2019, adolescent and young adult cancers contributed 23.5 million (21.9-25.2) DALYs to the global burden of disease, of which 2.7% (1.9-3.6) came from YLDs and 97.3% (96.4-98.1) from YLLs. Cancer was the fourth leading cause of death and tenth leading cause of DALYs in adolescents and young adults globally. Interpretation Adolescent and young adult cancers contributed substantially to the overall adolescent and young adult disease burden globally in 2019. These results provide new insights into the distribution and magnitude of the adolescent and young adult cancer burden around the world. With notable differences observed across SDI settings, these estimates can inform global and country-level cancer control efforts. Copyright (C) 2021 The Author(s).
