The influence of different exposure regimes of low-intensity extremely high-frequency electromagnetic radiation on the growth rate of solid Ehrlich carcinoma in mice has been studied. It was shown that, at an optimum repetition factor of exposure (20 min daily for five consecutive days after the tumor inoculation), there is a clearly pronounced frequency dependence of the antitumor effect. The analysis of experimental data indicates that the mechanisms of antitumor effects of the radiation may be related to the modification of the immune status of the organism. The results obtained show that extremely high-frequency electromagnetic radiation at a proper selection of exposure regimes can result in distinct and stable antitumor effects.

Collaborative management of severe periodontal-endodontic lesion with intense lip sucking: a case report.
BMC Oral Health
January 2025
Qingdao Municipal Hospital, Shandong, 266071, China.
Background: Lip behaviors can lead to maxillofacial developmental disorders such as anterior open bite, posterior crossbite, increased overjet, and a higher risk of developing a Class II malocclusion. However, lip-sucking, a behavior often underreported and overlooked, may adversely affect the periodontal health of permanent teeth in adolescents under extreme conditions if not promptly identified and managed.
Case Presentation: We report a unique case of an 11-year-old boy with a severe periodontal-endodontic lesion on tooth 32, caused by prolonged, high-frequency, and high-intensity lip sucking.

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) categorizes postpartum depression (PPD) as a subtype of Major Depressive Disorder (MDD) with peripartum onset, generally arising within the initial trimester following delivery. This acute psychiatric condition is characterized by feelings of worthlessness, insomnia, extreme anxiety, or maternal neglect. Intranasal oxytocin (OT) and transcranial magnetic stimulation (TMS) have the potential to address impaired social cognition; nonetheless, their neuronal underpinnings, along with their safety and efficacy, are little comprehended.

Low-frequency noise in detection systems significantly affects the performance of ultrasensitive and ultracompact spin-exchange relaxation-free atomic magnetometers. High frequency modulation detection helps effectively suppress the 1/ noise and enhance the signal-to-noise ratio, but conventional modulators are bulky and restrict the development of integrated atomic magnetometer modulation-detection systems. Resonant metasurface-based thin-film lithium-niobate (TFLN) active optics can modulate free-space light within a compact configuration.

Heat extremes become increasingly frequent and severe, posing adverse risks to public health and environment. Previous research on extreme heat mostly used meteorological observations or reanalysis data, which cannot well capture detailed spatial patterns. This study developed a seamless air temperature (T) dataset from remote sensing data to characterize the spatio-temporal variations of heat extremes in the Yangtze River Delta (YRD) from 2001 to 2023.

The tablet diversion strategy, based on in-line near-infrared (NIR) tablet press feed frame measurements, can be a key component of both batch and continuous oral solid dose manufacturing processes. It enables real-time, high-frequency monitoring and control, enhancing process understanding and compliance compared to conventional interval-based sampling methods. Central to this strategy are NIR spectrometers, which serve as PAT systems for in-line blend uniformity monitoring in the feed of the tablet press.
