Nanotechnology is a fast-rising market in catalytic research; however, the production of eco-friendly nanoparticles remains a significant challenge. In this study, silver nanoparticles (AgNPs) were synthesized from the agro-industrial waste of leaves of C. longa, C. aromatica, C. caesia, C. zedoaria, and C. amada at RT after 24 h, which was confirmed with UV-spectrophotometric evaluation between 320-520 nm. SEM revealed cubic and 30-50 nm AgNPs, while band-gap energy was presented as semi-conductors. Synthesized Ag [...]

Pain could be directly related to autonomous imbalance. To date, only one scientific work examining heart rate variability (HRV) and heart rate (HR) as the important parameters of autonomous nervous system (ANS) in the context of clinical routine acupuncture treatments for lumbosacral pain conditions is available in the listed databases. The present study aimed to investigate the short-term effects of HRV and HR, during and after the acupuncture needle stimulation in patients with lower back pain. Eighteen patients [...]

Sleep complaints are common in pediatric patients with central nervous system (CNS) tumors. These problems may result from disruption of normal homeostatic, circadian, neuroendocrine, and cardiorespiratory pathways and vary by tumor location and treatment received. Children with tumors within the hypothalamus and surrounding regions are prone to excessive daytime sleepiness. Sleep-related breathing disorders, especially those involving abnormal control of breathing, may occur in patients with tumors of the brainste [...]

The use of silicone rubber as an implant is limited due to its weak properties. In this study, the impact of various reinforcements, such as TiO2 or SiO2 nanoparticles, carbon, or polypropylene fiber micro reinforcements, on the mechanical, thermal, and viscoelastic properties of silicone rubber composites with RTV-4125 matrix was investigated. The composites were evaluated through several tests, including tensile, compression, FTIR, TGA, DMTA, and water adsorption tests. It was found that the composites' tensi [...]

Qigong is a form of traditional Chinese exercise combining breathing, movement, and meditation to improve fitness for the purpose of preventing disease and prolonging life. We review the clinical efficacy and underlying mechanism of the application of Qigong in the healthcare setting. In addition, we discuss topics such as the impacts on respiratory, cardiovascular function, and immune function, as well as studies of the influences on brain function and mental health. In summary, there is strong evidence of the cli [...]

Additive Manufacturing (AM) is a crucial component of the smart manufacturing industry. In this paper, we propose an automated quality grading system for the fused deposition modeling (FDM) process as one of the major AM processes using a developed real-time deep convolutional neural network (CNN) model. The CNN model is trained offline using the images of the internal and surface defects in the layer-by-layer deposition of materials and tested online by studying the performance of detecting and grading the failure [...]

Hospitals are one of the key contributors of pharmaceutical contaminants of emerging concern to the sewer systems. Hospitals wastewaters contain concentrations of pharmaceutical compounds between 3 and 150, which are higher than urban wastewater streams. However, dedicated treatments of the hospital effluents before discharge to the sewer system are not compulsory. Besides, conventional wastewater treatment plants have not been designed to remove pharmaceutical compounds effectively, and consequently, these micropo [...]

Background: Dementia erodes the quality of life of patients and their caregivers, and the growing dementia population threatens public finance in the health and social services. In addition to formal medical treatments, complementary and alternative medicine is applicable to dementia, in which acupuncture has become an option for prevention, remedy, and rehabilitation. Acupuncture is a traditional Chinese medical method that uses needle penetration at acupoints (specific points throughout the body which will be sti [...]

(1) Background: Lung transplantation is an increasingly utilized treatment for end-stage lung disease. Scarcity of organ donors limiting transplantation underscores the importance of optimal histocompatibility testing approaches to facilitate organ allocation and avoid immunologic rejection. Significant data has emerged over the past decade to define the role of alloantibodies against HLA in the pathogenesis of post-lung transplant complications. (2) Methods: Medical literature from 1996–2016 related to search term [...]

Background: Mild Cognitive Impairment [MCI] is a transition stage between normal aging and dementia. It seems to be useful to treat MCI before the onset of early dementia, though no pharmacological treatment is recommended [1]. These case studies aimed to assess the efficacy of long-term repetitive Transcranial Magnetic Stimulation [rTMS] treatment on cognition, and clinical changes, in elderly MCI patients. Methods: Three patients with MCI were treated by rTMS with different parameters of stimulation, targeting th [...]
