Objective: The goal of this study is to determine the risk of exposure to Legionella pneumophila in hotel golf courses located in the province of Malaga (Spain).
Method: Spray irrigation systems were analyzed as sources for spreading the Legionella bacterium. Spanish legislation requires that irrigation systems be monitored for their water quality as well as for reasons related to health and hygiene. Based on an observational study and non-parametric tests (Goodman-Kruskal Tau and uncertainty coefficient), this study states the regulatory enforcement among the systems and contributed to announce Legionella prevention. The quality criteria for recycled water, waste water treatment plant and well water were analyzed in relationship to the hotels' categories.
Results: Deficiencies were found in the preventive maintenance of irrigation systems, but no relationship exists between the type of water and the risk detected.
Conclusions: The study suggests that aerosolized water used in golf course watering systems could pose risk to the population by exposing them to Legionella.

Background: Heavy metal contamination, particularly from lead (Pb), poses a significant threat to plant agriculture worldwide, adversely affecting growth, physiological functions, and yield. Signalling molecules such as calcium and salicylic acid are known to mitigate various stresses in plants, prompting this study to explore their interaction with Pb stress in wheat.
Methods: A pot experiment was conducted in which wheat grains were primed with either distilled water, 5 mM calcium (Ca), or 0.

Background: Loss of bipolar electrograms immediately after pulsed field ablation (PFA) makes lesion durability assessment challenging.
Objective: The aim of this trial (NCT06700226) was to evaluate a novel ablation system that can optically predict lesion durability by detecting structural changes in the tissue during ablation.
Methods: Patients with paroxysmal atrial fibrillation underwent pulmonary vein isolation (PVI) using PFA (AblaView®, MedLumics).

Rice-crab co-culture is an environmentally friendly agricultural and aquaculture technology with high economic and ecological value. In order to clarify the structure and function of soil and water microbial communities in the rice-crab symbiosis system, the standard rice-crab field with a ring groove was used as the research object. High-throughput sequencing was performed with rice field water samples to analyze the species and abundance differences of soil bacteria and fungi.

This work explores an intelligent field irrigation warning system based on the Enhanced Genetic Algorithm-Backpropagation Neural Network (EGA-BPNN) model in the context of smart agriculture. To achieve this, irrigation flow prediction in agricultural fields is chosen as the research topic. Firstly, the BPNN principles are studied, revealing issues such as sensitivity to initial values, susceptibility to local optima, and sample dependency.

The blood-brain barrier (BBB) is a highly selective, semipermeable barrier critical for maintaining brain homeostasis. The BBB regulates the transport of essential nutrients, hormones, and signaling molecules between the bloodstream and the central nervous system (CNS), while simultaneously protecting the brain from potentially harmful substances and pathogens. This selective permeability ensures that the brain is nourished and shielded from toxins.
