Effects Of Hydrogen Peroxide, Temperature And Treatment Time On Degradation Propertiesof Polyethersulfone Ultrafiltration Membrane, Yasi̇n Özay, Erdal Yabalak, Nadi̇r Di̇zge

Turkish Journal of Chemistry

Oxidative cleaning agents such as hydrogen peroxide (H2O2) and sodium hypochlorite (NaClO) used in water and wastewater treatment play an important role in the degradation and rapid aging of the polymeric membranes. In addition, when the temperature is above the maximum operating range of the membrane, it negatively affects the membrane performance. H2O2, which is also known as a green and environmentally friendly strong oxidant because of releasing only water as a by-product, can provide good cleaning efficiency under temperature, but its influence on membrane aging is not fully understood. In this study, the aging of polyethersulfone (PES) ultrafiltration (UF) …

Effects Of Azadirachta Indica Extract On Inhibition Of Glutamate-Induced Neuronal Cell Apoptosis Via Preventing Excessive Mitophagy Activation And Inhibiting Endoplasmic Reticulum Stress In Ht-22 Cells, Kuljira Mongkolpobsin

Chulalongkorn University Theses and Dissertations (Chula ETD)

Neurodegenerative diseases (NDs) are the age-related diseases which represent a major cause of mortality in aging population nowadays. Previous studies have shown that glutamate, the most abundant excitatory neurotransmitter, significantly increases in extracellular fluid of the patient’s brain and is the cause of neurodegeneration in NDs. The increase of extracellular glutamate elevates reactive oxygen species (ROS) accumulation and calcium (Ca2+) which exacerbate mitochondrial function, followed by inducing MAPK pathway and endoplasmic reticulum (ER) stress, respectively. In addition, Ca2+ overload also triggers calpain, a Ca2+ dependent protease, activity which further stimulates Cdk5/p35/p25 signaling leading to neuronal apoptosis. Azadirachta indica A. Juss. …

The Fit-For-Purpose Model: Conceptualizing And Managing Chronic Nonspecific Low Back Pain As An Information Problem, Benedict M. Wand, Aidan G. Cashin, James H. Mcauley, Matthew K. Bagg, Gemma M. Orange, G. Lorimer Moseley

Physiotherapy Papers and Journal Articles

Chronic nonspecific low back pain (CNSLBP) is a complex and multifaceted problem. The following Perspective Piece tries to help make sense of this complexity by describing a model for the development and maintenance of persistent low back pain that integrates modifiable factors across the biopsychosocial spectrum. The Fit-for-Purpose model (FFPM) posits the view that chronic nonspecific low back pain represents a state in which the person in pain holds strong and relatively intransient internal models of an immutably damaged, fragile, and unhealthy back, and information that supports these models is more available and trustworthy than information that counters them. This …
