Purpose: To compare the effects of three common refractive surgeries on corneal biomechanics.
Methods: Two hundred seven patients who had refractive surgery were included in this study, of whom 65 received transepithelial photorefractive keratectomy (tPRK), 73 received femtosecond laser-assisted laser in situ keratomileusis (FSLASIK), and 69 received small incision lenticule extraction (SMILE). Each patient had biomechanical measurements using the Corvis ST (Oculus Optikgeräte GmbH) preoperatively and at 3 and 6 months postoperatively.
Cannabis is the most prevalent abused substance after alcohol, and its consumption severely harms human health and thus adversely impacts society. The identification and quantification of cannabis in urine play important roles in practical forensics. Excitation-emission matrix (EEM) fluorescence spectroscopy coupled with parallel factor (PARAFAC) analysis was developed to identify and quantify the four main ingredients of cannabis in urine samples.

The proposed structure involves two specialized arc discharge techniques. First, an oversaturated discharge fusion process creates a micro-arc spherical area on the fiber end face to form the first link type.

Methods: In this prospective cohort study, a total of 6,797 participants aged over 40 years based on NHANES 2005-2008 were analyzed. The severity of retinopathy was classified into 4 grades-no retinopathy, mild non-proliferative retinopathy (NPR), moderate to severe NPR, and proliferative retinopathy (PR).
Alzheimer's disease (AD) is a progressive neurodegenerative disorder without effective treatment. Accumulating evidence demonstrates the production and deposition of amyloid-β peptides (Aβ) in the pathological mechanism of this disease. In our study, we investigated the effect of an ozone intraperitoneal injection on AD pathology in APP/PS1 transgenic mouse model.

Prostate cancer (PCa) is the second leading cause of cancer death among men worldwide. About 70% of PCa patients were diagnosed at later stage, and metastasis has been observed. Additionally, the cure rate of PCa closely relies on the early diagnosis with biomarkers.

Study Design: Retrospective comparative study.
Settings: The study was conducted at a pain center of a university hospital.
Background: Electroacupuncture (EA) has been proved to be effective in treating certain neuropathic pain conditions. The mechanisms of pain relief by EA are not fully understood. There have been sporadic reports of damage in the peripheral nervous system (PNS) and regions of the central nervous system (CNS) at the ultrastructural level following peripheral nerve injury.
