The Structural And Functional Role Of Photosensing In Rgs-Lov Proteins, Zaynab Jaber

Dissertations, Theses, and Capstone Projects

Light provides organisms with energy and spatiotemporal information. To survive and adapt, organisms have developed the ability to sense light to drive biochemical effects that underlie vision, entrainment of circadian rhythm, stress response, virulence, and many other important molecularly driven responses. Blue-light sensing Light-Oxygen-Voltage (LOV) domains are ubiquitous across multiple kingdoms of life and modulate various physiological events via diverse effector domains. Using a small molecule flavin chromophore, the LOV domain undergoes light-dependent structural changes leading to activation or repression of these catalytic and non-catalytic effectors. In silico analyses of high-throughput genomic sequencing data has led to the marked expansion …

Molecular Dynamics Simulations Of Self-Assemblies In Nature And Nanotechnology, Phu Khanh Tang

Dissertations, Theses, and Capstone Projects

Nature usually divides complex systems into smaller building blocks specializing in a few tasks since one entity cannot achieve everything. Therefore, self-assembly is a robust tool exploited by Nature to build hierarchical systems that accomplish unique functions. The cell membrane distinguishes itself as an example of Nature’s self-assembly, defining and protecting the cell. By mimicking Nature’s designs using synthetically designed self-assemblies, researchers with advanced nanotechnological comprehension can manipulate these synthetic self-assemblies to improve many aspects of modern medicine and materials science. Understanding the competing underlying molecular interactions in self-assembly is always of interest to the academic scientific community and industry. …

Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky

Open Educational Resources

The goal of this preparatory textbook is to give students a chance to become familiar with some terms and some basic concepts they will find later on in the Anatomy and Physiology course, especially during the first few weeks of the course.

Organization and functioning of the human organism are generally presented starting from the simplest building blocks, and then moving into levels of increasing complexity. This textbook follows the same presentation. It begins introducing the concept of homeostasis, then covers the chemical level, and later on a basic introduction to cellular level, organ level, and organ system level. This …

Association Of Fish Oil And Physical Activity On Mobility Disability In Older Adults, Anoop T. Balachandran

Publications and Research

Purpose: This study aimed to examine whether long-term fish oil (FO) supplementation is associated with a lower risk of mobility disability and enhances benefits of physical activity (PA). Methods: A total of 1635 sedentary adults age 70 to 89 yr from the Lifestyle Interventions and Independence for Elders single-blinded randomized,multicenter clinical trial, which compared a structured PA program to a health education program. Primary outcome was incident major mobility disability (MMD), defined by loss of ability to walk 400 m, measured every 6 months for an average of 2.6 yr. Secondary outcomes included persistent mobility disability, Short Physical Performance Battery, …

Bacterial Lps At The Immune Modulating Component In Juzen-Taiho-To, Diego Montenegro

Dissertations, Theses, and Capstone Projects

Juzen-taiho-to (JTT) is an immune-boosting herbal formulation with an ideal balance of safety and efficacy. For example, JTT is clinically used in Japan to stimulate the immunological functions of cancer patients undergoing chemotherapy and radiation. Although the clinical effects of JTT are recognized, the active compounds and mechanism of action are unknown. The studies conducted previously in our laboratory associated several phytosterols and plant glycolipids with the potent immunostimulatory activity of JTT: namely, β-sitosteryl β-D-glucoside (BSSG), glucocerebroside (GluCer), digalactosyldiacylglycerol (DGDG) and monogalactosyldiacylglycerol (MGDG). However, these compounds, when further purified, exhibited little or no immunostimulatory activity. This suggested that the immunostimulatory …

Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella

Dissertations, Theses, and Capstone Projects

In addition to increased intake of sweet solutions by mammals, learning, particularly classically-conditioned “Pavlovian-like” learning, also plays an important role. An orosensory conditioned flavor preference (CFP) can be elicited by pairing one novel flavor (conditioned stimulus, CS+) with a fructose solution and a second novel flavor (CS-) with a saccharin solution. Rats will prefer the CS+ flavor in a subsequent 2-bottle choice test with both flavors mixed in saccharin. Previous pharmacological analyses revealed that systemic administration of dopamine (DA) D1 and D2 as well as NMDA, but not opioid, receptor antagonists eliminated the acquisition (learning) of fructose-CFP. Further, expression of …

Naturally-Derived Molecular Ensembles In Medicine, Materials Science And Evolutionary Biology: An Interdisciplinary Study, Silvio Panettieri

Dissertations, Theses, and Capstone Projects

The first chapter will introduce the work carried out in collaboration with the Govind laboratory at CCNY. Our quest was set forth to investigate the intimate relationship lying between chronic inflammation and tumor development. For at least the last fifteen years much research has been conducted on this topic; yet, the level of complexity arising from exceedingly interwoven biochemical pathways in mammals has resulted in slow advancements in this field. This is why we resorted to a simple yet powerful immunogenetic model organism, the fruit fly Drosophila melanogaster, in combination with the administration of the most common anti-inflammatory drug, …

Human Anatomy And Physiology Preparatory Course: Part 1 Of 4 (Interactive), Carlos Liachovitzky

Open Educational Resources

The overall purpose of these preparatory course set of learning objectives is to help students familiarize with some terms and some basic concepts they will find later in the Human Anatomy and Physiology I course.

These 40+ learning objectives to prepare for Human Anatomy and Physiology can be downloaded and played in a desktop, or laptop (windows exe file).

The entire course has four parts:

• Part 1
• Part 2
• Part 3
• Part 4

Each learning objective is followed by a set of multiple choice question similar to those found later in a Human Anatomy and Physiology course.

The organization and …

Human Anatomy And Physiology Preparatory Course (1st Edition), Carlos Liachovitzky

Open Educational Resources

The overall purpose of this preparatory course textbook is to help students familiarize with some terms and some basic concepts they will find later in the Human Anatomy and Physiology I course.

The organization and functioning of the human organism generally is discussed in terms of different levels of increasing complexity, from the smallest building blocks to the entire body. This Anatomy and Physiology preparatory course covers the foundations on the chemical level, and a basic introduction to cellular level, organ level, and organ system levels. There is also an introduction to homeostasis at the beginning.
