Field measurement of spray drift from a spray application by UAV.
Pest Manag Sci
January 2025
Silsoe Spray Applications Unit Ltd, Bedford, UK.
Background: To use unmanned aerial vehicles (UAVs) to deliver pesticides, new data are needed to allow regulators to conduct risk assessments. A field trial was conducted to obtain spray drift data relating to ground deposits and airborne spray resulting from a spray application delivered by a small UAV.
Results: A 12 m width area was sprayed with four passes of the UAV and spray deposits were collected within the sprayed area and up to 50 m downwind.
Abnormalities in Blood Parameters in Athletes Taking Anabolic Androgenic Steroidal Agents; an Observational Clinical Study.
Subst Abuse Rehabil
January 2025
Department of Pharmacology and Toxicology, Faculty of Medicine, Umm Al Qura University, Makkah, Saudi Arabia.
Background: Many studies indicate that high and multiple doses of anabolic-androgenic steroids (AAS) for athletic enhancement can result in serious and irreversible adverse effects. A study that includes laboratory blood testing to evaluate the direct effects of AAS agents among users has not been previously undertaken. The purpose of this study was to investigate the adverse effects of the use of AAS by athletes and to determine whether AAS use leads to changes in certain blood parameters.

March 2025
Community Health and Implementation Research Program, RTI International, Research Triangle Park, NC, USA.
Background: In response to the recent and growing shift from injecting heroin to smoking fentanyl, an increasing number of syringe services programs (SSPs) in the United States are distributing safer smoking supplies. There is a lack of research on whether safer smoking supply distribution is associated with increased SSP engagement and naloxone distribution from SSPs. Therefore, we aimed to assess predictors of safer smoking supply distribution by SSPs and estimate associations between safer smoking supply distribution and scale of harm reduction services.

January 2025
Department of Radiation Oncology, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.
Purpose: This study aimed to provide quantitative information for implementing Lattice radiotherapy (LRT) using a medical linear accelerator equipped with the Millennium 120 multi-leaf collimator (MLC). The research systematically evaluated the impact of varying vertex diameters and separations on dose distribution, peak-to-valley dose ratio (PVDR), and normal tissue dose.
Methods: A cylindrical Virtual Water™ phantom was used to create LRT treatments using the Eclipse version 16.
Bisphenol F (BPF) exposure impairs sperm quality and offspring development in male zebrafish.
Toxicol Appl Pharmacol
January 2025
Department of Preventive Medicine, Shantou University Medical College, Shantou 515041, Guangdong, China. Electronic address:
Background: Bisphenol F (BPF), a substitute for bisphenol A (BPA), is widely used in consumer products, increasing the potential for environmental exposure. Our study investigated the reproductive effects of BPF on adult male zebrafish and explored its toxicological mechanisms, as well as its intergenerational effects.
Methods: Adult male zebrafish were exposed to BPF concentrations of 0, 50, 500, 2500, and 5000 nM for 21 days.
