The effect of high-frequency low-intensity radiation on reproductive function was studied on C57Bl/6 and randombred mice. We revealed a progressive decrease in the number of offspring, prevalence of males over females in all generations, and the appearance of stillbirths. The decrease in the number of offspring was probably related to increased number of homozygotes and decreased number of heterozygotes in the population under the influence of nonthermal radiation.

Animal-based foods such as meat, dairy, and eggs contain abundant essential proteins, vitamins, and minerals that are crucial for human nutrition. Therefore, there is a worldwide growing demand for animal-based products. Since animal-based foods are vital resources of nutrients, it is essential to ensure their microbial safety which may not be ensured by traditional food preservation methods.

Article Synopsis
- This study examined how two levels of low-intensity vibration training (0.6 g and 1.0 g) affected muscle and bone recovery in mice after a muscle injury known as volumetric muscle loss (VML).
- Mice were divided into groups receiving either no treatment or varying levels of vibration training for 15 minutes a day over 8 weeks post-injury.
- Results showed that bone structure improved with vibration training, particularly at the 1.0 g level, while muscle function showed less significant enhancement, suggesting that vibration training may be more beneficial for bone recovery than for muscle after VML.
Transcutaneous neurostimulation parameters for neuropathic radicular pain: Results from a two period crossover randomized trial.

Department of Rheumatology, Saint-Philibert Hospital, Catholic University of Lille, Lomme, France.
Article Synopsis
- This study compares two types of transcutaneous neurostimulation (TENS) for treating chronic radicular pain: conventional high-frequency low-intensity current (c-TENS) vs. mixed current (m-TENS), which combines c-TENS with low-frequency high-intensity current.
- Seventy-four patients with chronic neuropathic pain participated in the trial and received both treatments in a randomized order over a month; the primary outcome measured was pain level using a Visual Analog Scale (VAS).
- Results showed no significant difference in pain relief between c-TENS and m-TENS, with similar tolerance levels for both, indicating that there’s no clear preference for either treatment method in managing chronic neuropathic radicular pain.
Precipitation patterns strongly affect vertical migration and methylation of mercury in legacy contaminated sites.
Water Res

College of Environmental & Resource Science, Zhejiang University, Hangzhou, 310058, China.
Article Synopsis
- Legacy-contaminated sites can leak mercury into the environment, which is harmful to both nature and people.
- When it rains a lot (especially frequently), mercury moves deeper into the soil more than when it rains heavily but less often.
- Rain also helps certain microbes turn mercury into a more toxic form called methylmercury, which can create bigger problems for the environment.
Transcranial Magnetic Stimulation-Induced Plasticity Improving Cognitive Control in Obsessive-Compulsive Disorder, Part II: Task-Based Neural Predictors of Treatment Response.

Background: Repetitive transcranial magnetic stimulation (rTMS) has the potential to increase the clinical effect of exposure with response prevention psychotherapy for obsessive-compulsive disorder (OCD). We investigated the use of task-based functional magnetic resonance imaging for predicting clinical outcomes to different rTMS protocols combined with exposure with response prevention in OCD.
Methods: Sixty-one adults with OCD underwent rTMS and exposure with response prevention and were randomized to different high-frequency rTMS conditions: left dorsolateral prefrontal cortex (n = 19), left presupplementary motor area (n = 23), and control stimulation at the vertex at low intensity (n = 19).
