In this study, an alternative approach was proposed where excess seawater would be added only during inoculation (DD) rather than daily addition (FD). Growth and metabolite contents of Tetraselmis sp. weren't affected for daily increase of 2% NaCl salinity. Tetraselmis sp. was then cultured in DD and FD pond. In DD pond, initial culture depth was 23.5cm and its depth reduced as no water was added; for FD pond, everyday sterilized seawater was added to maintain 20cm depth. DD pond had higher biomass productivity compared to FD pond, until DD pond was deeper than FD pond; metabolite content and FAME profile of Tetraselmis sp. were also similar in both cultures. Therefore, considering the simplicity in operation, halo tolerant microalgae can be grown in DD pond method.

Small glaciers situated in high mountainous areas are experiencing notable declines, characterized by unprecedented rates of ice loss in recent years. This study investigates the recent changes in surface elevation and mass loss occurring between 2010 and 2023 within the Alamkouh Glacier over three subperiods, one of the biggest glaciers in Iran and the Middle East. These assessments are derived from a combination of high-resolution LiDAR data in 2010 (with a spatial resolution of 20 cm) and multi-temporal surveys conducted using unmanned aerial vehicles (UAVs) in 2018, 2020, and 2023 (with spatial resolutions varied from 10 to 20 cm).

Delivering surgical services in low- and middle-income countries often requires adaptability and ingenuity due to resource limitations. This case report describes how a visiting surgical team in a Pacific Island nation overcame the absence of a diathermy foot pedal during a transurethral resection of the prostate by collaborating with both on-site and remote biomedical engineers. The team modified a handheld pencil diathermy to mimic foot pedal functionality.

Aims: Cardiogenic shock remains a significant cause of mortality despite multiple advancements in medical interventions. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides crucial circulatory support but also increases left ventricular (LV) after-load, potentially worsening outcomes. Effective LV unloading strategies can enhance patient survival during VA-ECMO treatment.

This study investigated the efficacy of two microalgae treatment systems (Chlorella vulgaris monoculture and a Chlorella vulgaris-S395-2-Clonostachys rosea symbiotic system) in treating aquaculture wastewater, under varying concentrations of synthetic strigolactone analog (GR24). By exposing the systems to four GR24 doses (0, 10, 10, and 10 M), we examined the impact on biomass growth, photosynthesis, and wastewater treatment. Elevated GR24 concentrations bolstered metabolism and photosynthesis in the systems, fostering rapid symbiont growth and enhanced treatment efficiency.

Pharmaceutical contaminants reaching natural aquatic ecosystems can affect fish behaviour, modifying activity patterns, foraging behaviour and antipredator responses. While laboratory-based studies can offer key insights, assessing the ecological relevance of these findings requires field-based approaches. Therefore, we examined the effects of oxazepam, a widely prescribed anxiolytic drug, on the behaviour of a cyprinid fish (the common roach, ) in the wild, combining slow-release exposure implants with continuous tracking via acoustic telemetry.
