ABSTRACT Background and Aims Human papillomavirus (HPV) vaccines have been available in China for only 8 years, and routine HPV testing is not recommended prior to vaccination. Therefore, evaluation of HPV vaccine effectiveness and the impact of pre‐vaccination HPV infection status on vaccine protective effect in Chinese women is warranted. Methods From June 2022 to June 2023, women aged 18 to 50 years without a history of cervical or uterine excision were recruited from three medical institutions. Baseline characteristics were compared between vaccinated and unvaccinated participants, with in

IntroductionThe field of poetry learning is currently facing significant challenges, primarily due to a lack of motivation and interest among students. This has resulted in educators encountering difficulties in identifying suitable educational alternatives. To address the latter issue, immersive learning has emerged as a potential solution, as it has been demonstrated to enhance motivation and learning outcomes in a multitude of fields.MethodsIn light of the aforementioned considerations, this field study seeks to examine the potential of virtual reality (VR) tools in enhancing the memorizati

Introduction: Osseo-integrated dental implants were traditionally load-free for up to six months while they healed. Patients usually feel dissatisfied with the long loading times. Several studies have been conducted to improve osseointegration, decrease loading time, and increase patient satisfaction.Objectives: This study aimed to evaluate and compare both clinically and radiographically the effect of hyaluronic acid (HA) versus Titanium-Platelet Rich Fibrin (T-PRF) in enhancing osseointegration around anterior maxillary dental implants.

METHODS: FDG PET images of 1839 male patients undergoing imaging for non-prostate and non-urinary bladder malignancy indications were retrospectively reviewed for the presence of incidental prostatic FDG uptake. Prostatic volume, calcification and the presence and pattern of FDG uptake were evaluated. Further follow-up prostatic evaluation results were comparatively assessed. RESULTS: Incidental prostatic FDG uptake was detected in 41 out of 1839 patients(2.2

Background: Dextromethorphan, the D-isomer of the codeine analog levorphanol, is a weak, noncompetitive N-Methyl-D-Aspartate (NMDA) receptor antagonist. It has been suggested that NMDA receptor antagonists induce preemptive analgesia when administered before tissue injury occurs, thus decreasing the subsequent sensation of pain. Materials and Methods: The study was conducted in the Dr. Ali Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran, between February 2005 and December 2006.

Sleep duration, quality, and rest-activity pattern-a measure for inferring circadian rhythm-are influenced by multiple factors including access to electricity. Recent findings suggest that the safety and comfort afforded by technology may improve sleep but negatively impact rest-activity stability. According to the circadian entrainment hypothesis, increased access to electric lighting should lead to weaker and less uniform circadian rhythms, measured by stability of rest-activity patterns. Here, we investigate sleep in a Maya community in Guatemala who are in a transitional stage of industria

Noisy galvanic vestibular stimulation (nGVS) has been shown to enhance postural stability during stimulation, and the enhancing effect has been observed to persist for several hours post-stimulation. However, these effects were observed without proper control (sham condition) and the possibility of experimental bias has not been ruled out. The lasting effect of nGVS on postural stability therefore remains in doubt. We investigated the lasting effect of nGVS on postural stability using a control (sham) condition to confirm or infirm the possibility of experimental bias. 28 participants received
