Molecular characterization of wheat dwarf virus isolates from Serbia based on complete genome sequences.

Introduction: Wheat dwarf virus (WDV), the species of the genus in the family , is a cereal virus commonly detected in several European, African and Asian countries that causes economic losses.

Methods: In the spring of 2019, a severe outbreak of wheat dwarfing and yellowing was observed in many winter wheat crops across Serbia. A total of 161 samples were tested for the presence of WDV and other common wheat viruses using double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA).

Complex Hippocampal Response to Thermal Skin Injury and Protocols with Hyperbaric Oxygen Therapy and Extract in Rats.

The aim of this study was to evaluate the alterations of the hippocampal function that may be related to anxiogenic response to thermal skin injury, including the morpho-functional alterations, and the effects of hyperbaric oxygen (HBO) and (FU) extract in the treatment of anxiety-like behavior that coincides with thermal skin injury. A rat thermal skin injury experimental model was performed on 2-month-old male rats. The evaluated therapeutic protocols included HBO and/or antioxidant supplementation.

Therapeutic approach to emotional reactions accompanied with thermal skin injury - from basic to epidemiological research.

In this editorial, we discuss the status of a therapeutic approach to emotional reactions accompanying thermal skin injuries. Burns are considered a major health problem, as well as an economic and social problem, with potentially devastating and life-changing consequences. They affect a wide range of patients with different damage mechanisms, varied depths, and localizations of the burns.

Numerical Investigation into In-Plane Crushing of Tube-Reinforced Damaged 5052 Aerospace Grade Aluminum Alloy Honeycomb Panels.

This paper aims to investigate the crashworthiness performance degradation of a damaged 5052 aluminum honeycomb panels under in-plane uniaxial quasi-static compression and the possibility of improving it using reinforcement tubes. The in-plane crushing behaviors and energy absorption capacities of the intact, damaged, and tube-reinforced damaged panels with different damage sizes in both X and X directions are numerically simulated by using the nonlinear FE method Abaqus/Explicit, and the crashworthiness performances are compared with each other. The validation of finite element model involves comparing the obtained simulation results with theoretical and experimental ones.
