Revolutionizing Free-Space Optics: A Survey of Enabling Technologies, Challenges, Trends, and Prospects of Beyond 5G Free-Space Optical (FSO) Communication Systems.

As the demand for high-speed, low-latency communication continues to grow, free-space optical (FSO) communication has gained prominence as a promising solution for supporting the next generation of wireless networks, especially in the context of the 5G and beyond era. It offers high-speed, low-latency data transmission over long distances without the need for a physical infrastructure. However, the deployment of FSO systems faces significant challenges, such as atmospheric turbulence, weather-induced signal degradation, and alignment issues, all of which can impair performance.

Ellagic Acid Potentiates the Inhibitory Effects of Fluconazole Against .

: Antifungal resistance to azoles, coupled with the increasing prevalence of infections, represents a significant public health challenge and has driven the search for new natural compounds that can act as alternatives or adjuvants to the current antifungals. Ellagic acid (EA) has demonstrated antifungal activity; however, its effects are not fully understood. In this study, we investigated the in vitro anti- activity of EA and its ability to potentiate the effects of fluconazole (FLZ) on : The Minimum Inhibitory Concentration (MIC) of EA was determined by broth microdilution and its interaction with FLZ was assessed using a checkerboard assay.

Association of 30-s Sit-to-Stand Power Test Outcome With Body Balance in Physically Active Older Adults.

Amount of serial sitting and standing movements has been employed in clinical and research settings to assess legs' muscular strength. In this cross-sectional study, we aimed to test the correlation between the 30-s sit-to-stand power test (30STSp) outcome and body balance in older adults. We evaluated physically active male and female (n = 51) individuals with an age range of 60-80 years (M = 69.

The presence of sexed sperm in bovine oviduct epithelial cells alters the protein profile related to stress and immune response.

Although sperm sexing technology has progressed considerably in the last decade, there are still challenges to fully understand the reason for the low fertility of sexed sperm. Thus, we aimed to evaluate the effect of sexed and non-sexed sperm on the proteome of bovine oviduct epithelial cells (BOECs). Semen from six Nellore bulls was used and one ejaculate from each bull was collected and separated into three fractions: non-sexed, sexed for X-sperm and sexed for Y-sperm.

A systematic review and meta-analysis investigating the impact of exercise interventions on heart rate variability in hemodialysis patients.

Patients with chronic kidney disease have a high incidence of cardiovascular diseases, and autonomic dysfunction has a determinant role in the relevant declines. Physical exercise influences heart rate variability and cardiac autonomic modulation. Thus, our objective was to systematically review, with a meta-analysis, the correlation between physical exercise interventions and alterations in cardiac autonomic modulation in hemodialysis patients.
