Ecological Assessment of Roodbest Wetland Using Algal Bioindicators

Soghra Ramzi

The Roodbast Wetland in Babolsar city is a crucial source of agricultural water and supports various living organisms near human settlements. Preserving the quality of this habitat is vital for both natural and human reasons. This study investigates the ecological status of Roodbast Wetland using algae as biological indicators of pollution. Diverse samplings were conducted in different seasons. Pollution levels were assessed using the Palmer index and various biological indicators. The study cataloged 81 genera across 7 phyla of algae. Chlorophyta had the highest species diversity, while Chrysophyta had the fewest. Peak algae proliferation occurred in summer and spring. Chlorophyta and Bacillariophyta were predominant throughout most of the year. In summer, Palmer’s pollution index peaked at stations 3 and 4, with a value of 35. In winter, stations 2, 4, and 5 showed minimal pollution with indices of 6, 9, and 7, respectively. During summer and autumn, all stations recorded Palmer indices exceeding 24. The primary cause of wetland pollution in spring is the influx of sub-branches from Babolrood, carrying village sewage and agricultural runoff. The rise in pollution in summer and autumn is due to elevated water temperatures, reduced rainfall, and increased extraction of lagoon water for rice replanting.

Interdisciplinary perspectives of Biological Anthropology in Iran

koohyar mohsenpour

Biological anthropology, as a branch of anthropology, studies the evidence of evolution, diversity, biological and cultural adaptation that has made us the modern humans we are. The centrality of "human" evolution in anthropology has led to the formation of interdisciplinary, methodological, and conceptual links with other sciences. Apart from the lack of access to topics such as primatology in Iran due to the lack of cultural, geographical, and research context, the study of genetic and physical characteristics of contemporary ethno-cultural and demographic groups, biological evolution, and environmental adaptation have constituted the majority of studies in this field. The lack of sufficient studies on the approaches and goals of biological anthropology and the failure to address the capacities of this science in recent years have led to its conceptual framework being less well known in Iran. Therefore, the present study, while showing the importance of interdisciplinary scientific communities, has attempted to assessment the approaches of biological anthropology in Iran by reviewing 92 articles from related research whose research was conducted in Iran. The selected articles claimed to be conducting anthropological research in terms of title, subject, method, and approach. The present study

Mohabat Nadaf

In this article, a new record of Astragalus suffalcatus Bunge, from section Dissitiflori Bunge of the genus Astragalus, is presented. This species occurs in northeastern Iran, in North Khorasan Province, and has previously been reported from Afghanistan and southwestern Pakistan. A herbarium specimen image, distribution map, conservation status map, and a description of the species are provided.

The effect of plasma water on the anatomical structure of beans (Vicia faba)

Zohreh Jafari

Objective: “Broad bean (Vicia faba) is important in many countries as a source of high protein percentage, amino acid ratios, mineral salts, and calcium. The use of new scientific methods and modified traditional methods such as plasma water have helped a lot to achieve of improved plant growth. This study was conducted to investigate the effect of plasma-activated water on growth and anatomical features of Vicia faba.

Method: After preparation , seeds were first soaked for 24 hours with water that had been activated with plasma for 5 minutes and 20 minutes, and with control water without plasma application. After planting, the pots were watered twice a week for 40 to 50 days. After this period, the anatomical features were examined.

Results: The results showed that in plants treated with vascular bundle dispersion, the growth and development of xylem vessels and the growth of the vegetative apical meristem were greater than in the control And the treated plants entered the reproductive phase faster.

Conclusions: plasma-activated water can increase the growth of faba bean plants by causing changes in anatomical and developmental characteristics.

According to the article results, use of plasma water is recommended to improve the performance of this plant.

Impact of Fraxinus Excelsior Leaf Extract on Post-Thaw Quality Parameters of Mouse (Mus Musculus) Sperm

Mahdi Jafarbeglou

Background: Cryopreservation of sperm is a critical technique in reproductive biology and medicine, allowing for long-term storage and use of genetic material. However, the freezing and thawing process can significantly impact sperm quality, affecting parameters such as motility, viability, and overall fertility potential.
Aim: This study explores the effect of an aqueous-alcoholic extract of Fraxinus excelsior on the quality parameters of sperm in NMRI mice after cryopreservation.
Methods: This study uses a descriptive correlation approach to examine the relationship between variables in sperm motility and cytoplasmic membrane health. Thirty male NMRI mice were divided into five experimental groups: healthy control, solvent control, and Fraxinus excelsior extract. Sperm motility, cytoplasmic membrane health, and oxidative stress levels were measured. Data analysis was performed using SAS 9.4 software, with mean comparisons using Duncan's test at a significance level of 0.05.

Comparison of uric acid serum level and other risk factors in patients with hypertrophic cardiomyopathy with healthy people

mohammadtaghi hedayati

Introduction:Hypertrophic cardiomyopathy(HCM)is a common inherited disease that can lead to acute cardiac complications.Since uric acid level is recognized as a long-term predictor for some cardiac diseases,this study aimed to compare serum uric acid levels and other risk factors between patients with HCM and healthy individuals.
Methods:This cross-sectional study was conducted on100individuals referred to a cardiology clinic.Participants were divided into two groups of50:those diagnosed with hypertrophic cardiomyopathy and non-affected individuals,who were followed for one year.Patients were compared based on age, history of alcohol consumption,myocardial infarction,and measured uric acid levels.
Results:The study found that variables such as age(P<0.001), body mass index(BMI)(P=0.017), history of alcohol consumption(P=0.006),repeat percutaneous coronary intervention (PCI)(P=0.022),myocardial infarction(P=0.041),and cardiac-related death(P=0.003)were significantly associated with HCM patients compared to the control group. Overall, major adverse cardiac events(MACE)were also significantly linked to the case group(P<0.001).However,no significant association was found between uric acid levels and any of the variables.In the long-term analysis,smoking was the only factor that increased the risk of cardiovascular events by nearly27-fold.
Conclusion:The results indicated that age, history of alcohol consumption, and prior myocardial infarction are risk factors associated with HCM.Uric acid levels did not prove to be a predictor of cardiovascular events within one year in patients with hypertrophic cardiomyopathy.
