Aim: We intended to elucidate the relationship between mentalizing capacity and affective states by investigating the mediatory role of emotion dysregulation.

Methods: A sample of nonclinical Iranian adults ( = 445) completed a battery of online self-report measures comprising the Positive and Negative Affect Schedule (PANAS), Mentalization Scale (MentS), and Difficulties in Emotion Regulation Scale (DERS).

Results: Correlational analyses demonstrated that self- and other-related mentalizing were significantly and inversely associated with emotion dysregulation, which in turn was strongly linked with positive and negative affects.

Body mass plays a crucial role in determining the mass-specific energy expenditure during terrestrial locomotion across diverse animal taxa, affecting locomotion patterns. The energy landscape concept offers a framework to explore the relationship between landscape characteristics and energy expenditure, enhancing our understanding of animal movement. Although the energy landscape approach solely considers the topographic obstacles faced by animals, its suitability compared to previous methods for constructing resistance maps and delineating corridors has not been comprehensively examined.

For the conservation of wild species, it is important to understand how landscape change and land management can affect gene flow and movement. Landscape genetic analyses provide a powerful approach to infer effects of various landscape factors on gene flow, thereby informing conservation actions. The Persian squirrel is a keystone species in the woodlands and oak forests of Western Asia, where it has experienced recent habitat loss and fragmentation.

Article Synopsis
  • Genomic surveillance of SARS-CoV-2 is essential for tracking and understanding virus variants, especially in terms of transmissibility and severity; a study in Iran analyzed 330 genomes from the sixth wave of COVID-19 and compared them to previous waves.
  • The sequencing process involved extracting viral RNA from clinical samples and employing advanced sequencing technologies, revealing a shift in prevalent variants over six pandemic waves, from clades like V and L in the first wave to the Omicron variant in the sixth.
  • The findings highlight the importance of genome sequencing for detecting new variants, guiding public health responses, and preparing Iran for monitoring other respiratory diseases beyond COVID-19.

Spearmint essential oil (SEO), one of the economically valuable natural products, has special importance in the food, pharmaceutical, and perfumery industries due to its antifungal, antioxidant, and enzyme inhibitory properties. In this study, we optimized and evaluated the effect of three pre-treatments on the extraction of SEO for quantity and quality: ultrasonic bath (UB), water to material ratio-ultrasonic bath (W/M-UB), and cold plasma-ultrasonic bath (CP-UB). Three experiments were designed using the central composite design (CCD) of response surface methodology (RSM).

Natural mineral licks are ecologically valuable resources to meet the physiological needs of herbivores, particularly in temperate forests. Importantly, licking sites can harbor high anthropogenic risk for conservation-dependent herbivores through higher chance of pathogen spillover from livestock and increased levels of poaching risks. However, to the best of our knowledge, there is no information on the mineral lick use in temperate forests of west Asia and the Caucasus where a few threatened deer species exist.

Due to their high sensitivity, simplicity, portability, self-contained, and low cost, the development of electrochemical biosensors is a beneficial way to diagnose and anticipate many types of cancers. An electrochemical nanocomposite-based aptasensor is fabricated for the determination of miRNA-128 concentration as the acute lymphoblastic leukemia (ALL) biomarker for the first time. The aptamer chains were immobilized on the surface of the glassy carbon electrode (GCE) through gold nanoparticles/magnetite/reduced graphene oxide (AuNPs/FeO/RGO).

Background: Since the first appearance of SARS-CoV-2 in China in December 2019, the world witnessed the emergence of the SARS-CoV-2 outbreak. Due to the high transmissibility rate of the virus, there is an urgent need to design and develop vaccines against SARS-CoV-2 to prevent more cases affected by the virus.

Objective: A computational approach is proposed for vaccine design against the SARS-CoV-2 spike (S) protein, as the key target for neutralizing antibodies, and envelope (E) protein, which contains a conserved sequence feature.

Article Synopsis
  • The study focused on the Caspian green lizard to understand how Pleistocene climate changes affected its genetic structure and phylogenetic relationships.
  • It involved analyzing genetic data from 39 lizards and other related species, identifying two main clades that split during the Pleistocene.
  • The findings suggest that historical climate conditions shaped the lizard's distribution, with specific regions acting as refuges during colder periods, leading to genetic diversity and expansion in warmer times.

Zookeys

August 2019

Department of Entomology, State Museum of Natural History Stuttgart, Rosenstein 1, 70191 Stuttgart, Germany State Museum of Natural History Stuttgart Stuttgart Germany.

Two new species of the mayfly family Oligoneuriidae are described based on larval specimens recently collected in Iran. The first new species, Godunko & Staniczek, , can be distinguished from all its congeners by the presence of pronounced protuberances posteromedially on abdominal terga, highly reduced paracercus, large lamella of gill I, and setation on hind margin of middle and hind femora confined to their basal halves. The second species, Bojková, Godunko, & Staniczek, , remarkably belongs to a mostly Afrotropical genus.
