Li Professor of Biomedical Sciences Florenz Plassmann Dean, College of Arts and Sciences 3 ABSTRACT LU, QIPING, Ph.D., May 2020, Molecular and Cellular Biology Investigation of the Zinc-Mitophagy Signaling in Hypoxic Cells Director of Dissertation: Yang V. Li Zinc is one of the most essential trace elements in the body. The concentration of intracellular free zinc is strictly regulated. The abnormal zinc concentration has been implicated in numerous clinical manifestations including ischemic stroke. Zinc homeostasis is achieved by proteins and organelles which sequester zinc or release zinc. Mitochondria are the power plants of the cell, the proper function of mitochondria is crucial for cellular metabolisms and physiological activities, their quality and quantity are regulated by mitophagy through selectively removing damaged mitochondria. Emerging evidence over the past decade has shown that zinc affects mitochondria in response to ischemia. It is progressively clear that zinc-mitochondrial interactions occur in and contribute to ischemic injury. Among the pathological effects of zinc accumulation on mitochondria, zinc induced release and accumulation of ROS draws special interest. ROS is a major cause of mitochondrial damage and initiates mitophagy.

  • An Approach to the Influence of Particle Size Distribution of Leuco Vat Dye Converted by a Reducing Agent
    Fibers and Polymers 2006, Vol.7, No.2, 164-168 An Approach to the Influence of Particle Size Distribution of Leuco Vat Dye Converted by a Reducing Agent Woo Sub Shim*, Jung Jin Lee1, and Renzo Shamey Fiber and Polymer Science Program, North Carolina State University, Raleigh, NC 27695-8301, USA 1Department of Textile Engineering, Dankook University, Seoul 140-714, Korea (Received January 25, 2006; Revised March 23, 2006; Accepted April 2, 2006) Abstract: Three vat dyes have been applied to regular viscose rayon and their dyeing and wash fastness properties were eval- uated. Particle size determination was undertaken to obtain information about the size of dye particles converted by a reduc- ing agent, to see if dye particle size has an affect on dyeing properties of regular viscose rayon. It is observed that viscose rayon exhibits more dyeability with reducing agent concentrations between 5-7.5 g/l. Also, we found that the vat dyeing sys- tem is greatly affected by the particle size of the vat dye converted to leuco form by a reducing agent. Keywords: Particle size, Particle size distribution, Reducing agent, Viscose rayon, Vat dye, Dyeing properties, Wash fastness Introduction (Na2S2O4). The name “hydro” is commonly used for sodium hydrosulfite in the dyehouse. Reduction is done in the presence Vat dyes are used to dye cellulosic fibers in relatively dull of sodium hydroxide (NaOH) which is usually called caustic. shades requiring good fastness. They are insoluble in water The quantities of caustic and hydro required depend on how and cannot be used directly for dyeing cellulosic fibers.

  • Reduction Clearing of Simulated Disperse Dyed PLA Fabrics and Their Tensile Properties
    Indian Journal of Fibre & Textile Research Vol. 38, March 2013, pp. 22-28 Reduction clearing of simulated disperse dyed PLA fabrics and their tensile properties Gulzar A Baiga University College of Textile Engineering, B.Z.U 60800 Multan, Punjab, Pakistan Received 18 October 2011; revised received and accepted 19 March 2012 Polylactic acid (PLA) knitted fabric has been subjected to various textile wet processes, viz. scouring, bleaching and simulated disperse dyeing. Reduction clearing (RC) has been performed at various process conditions such as concentrations of sodium dithionite and sodium carbonate, bath temperature and process time and a full factorial experiment is designed. The results show that the pretreatment processes and RC parameters have pronounced effects on tensile properties of PLA yarns. Statistical analysis of variance is performed which show significant differences at a confidence interval of 99%. Attenuated total reflectance infrared spectroscopy of the PLA fabric is carried out to investigate chemical changes on fibre surface. Scanning electron microscopy reveals that the bleaching causes the formation of slits in the fibres. Since bleached fibres are already porous, the strength of PLA yarns is further decreased during simulated disperse dyeing and reduction clearing processes.

  • Luminol Synthesis
    Luminol Synthesis Objective To develop organic lab techniques and synthesize luminol (5-amino-2,3-dihydro-1,4- phthalazinedione). Background Luminol is a popular star on a variety of crime scene investigation programs. Luminol luminesces when exposed to blood, and it is often used to find traces of blood at a crime scene. However, once you understand that luminol emits a photon after its oxidized, you realize that the heme in hemoglobin is simply catalyzing the oxidation of luminol. Thus, blood is not necessary; luminol will luminesce in the presence of any oxidizing agent (like bleach) or in the presence of O2 and a catalyst. NH2 O NH2 O NH2 O * – OH O2 NH N O + N2 eq 1 NH N O O O O The excited molecule produced in equation one relaxes to its ground state by releasing a photon. NH2 O * NH2 O O O + hν eq 2 O O O O To make luminol, we will follow the synthesis drawn in Scheme 1.

Heat the test tube over a microburner until the solid dissolves. Add 0.8 mL of triethylene glycol to the test tube. Clamp the test tube to a ring stand, insert a thermometer into the test tube (use a two holed rubber stopper, one hole for the thermometer and the other to make certain that the system is not sealed), and connect the side arm to a vacuum source.
