In an exploratory effort to find a new way to make high-performance composites used in ballistic protective applications, matrix-free Spectra® fiber-reinforced polymeric composites are produced via a novel processing method called high-temperature high-pressure sintering. Mechanical testing at ambient and elevated temperatures proves that the fibers can maintain their properties after processing. The characteristics and properties of the final products vary with different processing conditions. Their microstructure and morphology were investigated using SEM and WAXD. Their mechanical properties, including interlayer adhesion, rigidity, and ballistic performance, were measured and compared with those of the conventional composites. The sintering mechanism is proposed and verified. Spectra cloth is capable of being shaped to produce complex double curvatures by a thermoforming process, using a simple hemispherical mold. Success in different molding sequences and procedures shows the versatility in manufacturing. The theoretical background for the thermoformability is explained in terms of molecular interaction, microstructure, and morphology. Selective thermomechanical properties of the molded structures were measured. By combining the knowledge and information from the aforementioned studies, the process-structure-property relationship is established, which gives in-depth and better understanding of this unique high-temperature high-pressure sintering process for consolidating Spectra cloth. © 2005 Wiley Periodicals, Inc.

The association between methionine intake and cognitive function is inconclusive. We aimed to assess the association between methionine intake and cognitive function in Chinese adults and to explore the interaction between methionine and lead intake. Data from 4852 adults aged ≥55 years from the China Health and Nutrition Survey were used. Cognitive function was measured in 1997, 2000, 2004, and 2006. A 3-day, 24-hour recall was used to assess methionine and lead intake from different protein sources. Multivariable mixed linear regression was used in the analyses. Total methionine intake was positively correlated with cognition. There was a significant interaction between animal methionine and lead intakes. In subgroup analyses, across the quartiles of animal methionine intake, the regression coefficients (95% CI) for global cognition were 0.00, 0.57 (0.17 to 0.98), 1.18 (0.73 to 1.62), and 1.80 (1.31 to 2.29), respectively, while they were 0.00, −0.73 (−1.12 to −0.34), −0.83 (−1.26 to −0.41), and −1.72 (−2.22 to −1.22) across the quartiles of plant methionine intake, respectivelyThe association between animal methionine intake and cognition was stronger among adults with a low lead intake. In conclusion, animal methionine and plant methionine intake were positively and inversely associated with cognition, respectively. Lead intake modified the association between animal methionine intake and cognition.

Background: Recurrence of postoperative adhesions is one of the most important factors for poor reproductive outcomes after hysteroscopic surgery, particularly in cases diagnosed with severe intrauterine adhesions (IUAs), where the recurrence rate is significantly higher. This study aims to explore the effectiveness of the electrical muscle stimulation combined with ultrasound acupuncture therapy in preventing the recurrence of IUAs and improving reproductive outcomes after operative hysteroscopy. Methods: This study is a single-center, randomized controlled trial. A total of 210 patients with IUAs will be randomly assigned into 2 groups according to the ratio of 1:1, as the treatment group and the control group. Participants will receive the electrical muscle stimulation combined with ultrasound acupuncture therapy and oral hormone supplementation or receive oral hormone supplementation only. The primary outcome was the clinical response rate. There were 3 menstrual cycles of treatment and 3 menstrual cycles of follow-up in this study. Ethics and Dissemination: This study protocol was approved by the Ethics Committee of the Reproductive Hospital of Guangxi Zhuang Autonomous Region (approval number: KY-LL-2022-06). This trial will be conducted in accordance with the principles of the Declaration of Helsinki as well as Good Clinical Practice. Study results will be disseminated at academic presentations and publications in peer-reviewed journals.

Female pelvic floor dysfunction (FPFD) is a series of conditions caused by the displacement or dysfunction of the patient's pelvic organs due to defects, injuries, and deterioration of the pelvic floor supportive structures, with stress urinary incontinence and pelvic organ prolapse being the most common. The mechanism of pelvic floor dysfunction is complex and not yet fully understood, and is often related to one or more functional abnormalities of muscles, connective tissues, fascia, nerves and blood vessels. Specialized clinicians are often unable to cover the comprehensive medical professional information of various specialties such as gynecology and obstetrics, urology, anus and intestines, imaging, etc., and the systematic and comprehensive diagnosis and treatment of the disease will be limited. The application of artificial intelligence concepts in the medical field not only improves the diagnostic efficiency of physicians, but also provides reference and basis for the development of comprehensive treatment programs. This article follows and draws on the diagnosis and treatment process of pelvic floor dysfunction recommended in various guidelines, incorporates physical therapy techniques into the conventional non-surgical treatment of pelvic floor dysfunction, provides guidance for the diagnosis and treatment of pelvic floor dysfunction, and briefly introduces the clinical application and value of pelvic floor intelligent diagnosis and treatment in pelvic floor dysfunction.

The endometrium is an important part of the uterus. The human endometrium is a complex and dynamic tissue that goes through phases of growth and regression during any menstrual cycle. A thin endometrium might be relevant to a lower rate of implantation as well as a higher rate of miscarriage. Several treatments have been developed for thin endometrium, such as granulocyte colony-stimulating factor, stem cell therapy, acupuncture and physical therapy, among others. These approaches have been shown to have effects on the endometrium related to reducing the area of fibrosis, increasing the number of glands, promoting angiogenesis, increasing endometrial thickness, improving tissue structure, and increasing pregnancy rates. This review summarizes the key role of these treatments in repairing thin endometrium and improving clinical pregnancy rates

Background:Recurrence of postoperative adhesions is one of the most important factors for poor reproductive outcomes after hysteroscopic surgery, particularly in cases diagnosed with severe intrauterine adhesions (IUAs), where the recurrence rate is significantly higher. This study aims to explore the effectiveness of the electrical muscle stimulation combined with ultrasound acupuncture (ULTRA-EMS) therapy in preventing the recurrence of IUAs and improving reproductive outcomes after operative hysteroscopy.Methods:This study is a single-center, randomized controlled trial. A total of 210 patients with intrauterine adhesions will be randomly assigned into two groups according to the ratio of 1:1, as the treatment group and the control group. Participants will receive the ULTRA-EMS therapy and oral hormone supplementation or receive oral hormone supplementation only. The primary outcome was the clinical response rate. There were three menstrual cycles of treatment and three menstrual cycles of follow-up in this study.Ethics and Dissemination: This study protocol was approved by the Ethics Committee of the Reproductive Hospital of Guangxi Zhuang Autonomous Region (approval number: KY-LL-2022-06).
