Exercise Training Attenuates Ovariectomy-Induced Alterations in Skeletal Muscle Remodeling, Apoptotic Signaling, and Atrophy Signaling in Rat Skeletal Muscle
Get PDFPurpose The effects of aerobic exercise training on soleus muscle morphology, mitochondria-mediated apoptotic signaling, and atrophy/hypertrophy signaling in ovariectomized rat skeletal muscle were investigated. Methods Female Sprague-Dawley rats were divided into control (CON), ovariectomy (OVX), and ovariectomy plus exercise (OVX+EX) groups. After ovarian excision, exercise training was performed using a rat treadmill at 20 m/min, 50 min/day, 5 days/week for 12 weeks. Protein levels of mitochondria-mediated apoptotic signaling and atrophy/hypertrophy signaling in the skeletal muscle (soleus) were examined through western immunoblot analysis. Results The number of myocytes and myocyte cross-sectional area (CSA) were increased and the extramyocyte space was decreased in the OVX group compared to those in the CON group. However, aerobic exercise training significantly increased myocyte CSA and decreased extramyocyte space in the OVX+EX group compared to those in the OVX group. The protein levels of proapoptotic signaling and muscle atrophy signaling were significantly increased, whereas the protein levels of muscle hypertrophy signaling were significantly decreased in the OVX group compared to that in the CON group. Aerobic exercise training significantly decreased the protein levels of proapoptotic signaling and increased the protein level of antiapoptotic protein in the OVX+EX group compared to that in the OVX group. Aerobic exercise training significantly increased the protein levels of hypertrophy signaling and decreased protein levels of atrophy signaling in the OVX+EX group compared to those in the OVX group. Conclusions Treadmill exercise improved estrogen deficiency-induced impairment in skeletal muscle remodeling, mitochondria-mediated apoptotic signaling, and atrophy/hypertrophy signaling in skeletal muscle

COVID-19 Oral History Project: Interview with Monica Valle
Get PDFThe interview discusses how the interviewee adapted and lived through the COVID-19 pandemic. The person who was interviewed was Monica Valle in Edinburg by Carolina Flores in San Antonio for our US History 1302 class. Monica discusses how her life, work, and family life changed and was really affected by COVID-19, from the limited amount of time she got to spend with her family, to the healthcare rules that were taking place at work to help slow the spread
Deep Learning Modalities for Biometric Alteration Detection in 5G Networks-Based Secure Smart Cities
Get PDFSmart cities and their applications have become attractive research fields birthing numerous technologies. Fifth generation (5G) networks are important components of smart cities, where intelligent access control is deployed for identity authentication, online banking, and cyber security. To assure secure transactions and to protect user’s identities against cybersecurity threats, strong authentication techniques should be used. The prevalence of biometrics, such as fingerprints, in authentication and identification makes the need to safeguard them important across different areas of smart applications. Our study presents a system to detect alterations to biometric modalities to discriminate pristine, adulterated, and fake biometrics in 5G-based smart cities. Specifically, we use deep learning models based on convolutional neural networks (CNN) and a hybrid model that combines CNN with convolutional long-short term memory (ConvLSTM) to compute a three-tier probability that a biometric has been tempered. Simulation-based experiments indicate that the alteration detection accuracy matches those recorded in advanced methods with superior performance in terms of detecting central rotation alteration to fingerprints. This makes the proposed system a veritable solution for different biometric authentication applications in secure smart cities
Treatment of Prodcued Water Using Ferrate (VI) and Directional Solvent Extraction
Get PDFOil field fracking operations creates by-product “produced water” that is highly variable in composition and difficult to treat. This study aims to examine two novel treatment processes together in improving the quality of a synthetic, hypersaline produced water, and examines if effluent would be suitable for reuse. Here, we examine the ability of ferrate (VI) to coagulate organic and inorganic compounds to reduce turbidity while the efficacy of diisopropylamine (DIPA) in water extraction from the subsequent hypersaline solutions was also assessed under a variety of temperature ranges. For the final product water that is separated and treated through both processes, various characteristics were examined. Of note, significant reductions in turbidity (95.07% - 97.66% removal) and salinity (94.2% - 99.13% rejection) were observed at a variety of hypersaline concentrations and temperature ranges. Results indicate that this treatment process may show a favorable per-unit treatment cost compared to conventional processes
