Biodiversity of aquatic organisms in the Mekong Delta, Vietnam.

Background: The Mekong River is the 10 largest river in the world. It is recognised as the most productive river in Southeast Asia and economically essential to the region, with an estimated 60-65 million people living in the lower Mekong Basin. The Mekong Delta within Vietnam is considered a highly vulnerable ecosystem under threat from increasing anthropogenic pressure, such as dam construction and, as a consequence, the Delta is sinking and altering the natural hydrological cycle.

Is African non-annual killifish Fundulopanchax gardneri (Teleostei; Cyprinodontiformes; Nothobranchiidae) true non-annual?

Background: Annual or seasonal killifishes (Cyprinodontiformes: Nothobranchiidae) are unique among fish in their ability to enter into developmental arrests (diapauses: DI, DII, and DIII). They have a short lifespan and their embryos are exceptionally tolerant to a variety of environmental stresses. These traits make them a popular model for studying vertebrate diapause, aging, stress tolerance, genome adaptation, and evolution.

The Effect of Chromosomes on Courtship Behavior in Sibling Species of the Group.

Prezygotic isolation mechanisms, particularly courtship behavior, play a significant role in the formation of reproductive barriers. The action of these mechanisms leads to the coexistence of numerous closely related insect species with specific adaptations in a shared or adjacent territory. The genetic basis of these mechanisms has been studied using closely related Drosophila species, such as the group.

[Evaluation of the effectiveness of the third stage of rehabilitation after a knee joint injury in persons of older age groups by means of physiotherapy exercises.].

The main task in the rehabilitation of athletes with traumatic injuries of the knee joint and surrounding soft tissues is effective and painless recovery at all stages of treatment. The aim of this work is to introduce a set of physical exercises for the treatment and prevention of traumatic injuries of the knee joint in middle-aged and elderly patients at the third stage of rehabilitation treatment (ICD-10: S80-S89). To date, there is no single regulated program for the management of middle-aged and elderly patients at the outpatient stage.

Experimental modeling of selective photodestruction of skin angiodysplasia by laser radiation with a wavelength of 525 nm.

Until now, the problem of effective treatment of skin angiodysplasia remains relevant. To solve it and improve the results of the treatment of this vascular pathology of the skin, photodestruction by laser radiation is considered, which provides a selective effect on the skin with minimal damage to the surrounding tissues. For selective photodestruction in the treatment of angiodysplasia of the skin, one can consider laser radiation with a wavelength of 520 ± 5 nm in the "green" spectral range, located close to the absorption peaks of hemoglobin and oxyhemoglobin chromophores.
