Discharge And Role Of Acetylcholine Pontomesencephalic Neurons In Cortical Activity And Sleep-Wake States Examined By Optogenetics And Juxtacellular Recording In Mice, Youssouf Cisse, Hanieh Toossi, Masaru Ishibashi, Lynda Mainville, Christopher S. Leonard, Antoine Adamantidis, Barbara E. Jones

NYMC Faculty Publications

Acetylcholine (ACh) neurons in the pontomesencephalic tegmentum (PMT) are thought to play an important role in promoting cortical activation with waking (W) and paradoxical sleep [PS; or rapid eye movement (REM)], but have yet to be proven to do so by selective stimulation and simultaneous recording of identified ACh neurons. Here, we employed optogenetics combined with juxtacellular recording and labeling of neurons in transgenic (TG) mice expressing ChR2 in choline acetyltransferase (ChAT)-synthesizing neurons. We established in vitro then in vivo in anesthetized (A) and unanesthetized (UA), head-fixed mice that photostimulation elicited a spike with short latency in neurons which could …

Hypoglycemic, Hypolipidemic And Antioxidant Effects Of Iridoid Glycosides Extracted From: Corni Fructus: Possible Involvement Of The Pi3k-Akt/Pkb Signaling Pathway, Jiefang Kang, Chen Guo, Rodolfo Thome, Ning Yang, Yuan Zhang, Xing Li, Xiaoyan Cao

Department of Neurology Faculty Papers

Iridoid glycosides (CIG) are the major component of Corni fructus. In this work, we researched the antioxidative, hypoglycemic and lowering blood lipids effects of CIG on diabetic mice induced by a high-fat diet (HFD) and streptozotocin (STZ). Furthermore, to investigate the molecular mechanism of action, the phosphorylation and protein expression of phosphoinositide 3-kinase (PI3K) and its downstream proteins, such as insulin receptor (INSR), protein kinase B (Akt/PKB) and glucose transporter 4 (GLUT4) have been detected. The results showed that CIG significantly improved oral glucose tolerance in diabetic mice. Biochemical indices also revealed that CIG had a positive effect on lipid …

Effects Of Light At Night On Laboratory Animals And Research Outcomes, Kathryn M. Emmer, Kathryn L. G. Russart, William H. Walker Ii, Randy J. Nelson, A. Courtney Devries

Clinical and Translational Science Institute

Light has substantial influences on the physiology and behavior of most laboratory animals. As such, lighting conditions within animal rooms are potentially significant, and often underappreciated variables within experiments. Disruption of the light/dark cycle, primarily by exposing animals to light at night (LAN), disturbs biological rhythms and has widespread physiological consequences due to mechanisms such as melatonin suppression, sympathetic stimulation, and altered circadian clock gene expression. Thus, attention to the lighting environment of laboratory animals and maintaining consistency of a light/dark cycle is imperative for study reproducibility. Light intensity as well as wavelength, photoperiod, and timing are all important variables. …

Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes

Electronic Theses and Dissertations

Bacterial uterine infections inflict major losses on the equine breeding industry. These infections usually arise from bacteria introduced at breeding. Micro-currents propelled by ciliated cells between the folds of the uterus and cervix have been proposed as a means by which contaminants are expelled. Previous data have shown possible ciliary micro-currents propelling carbon particles, occasionally rotating, through cervical folds. However, adherence to the epithelium may have interfered with movement of carbon in these studies. Therefore, we tested potentially non-adherent substances to reveal ciliary micro-currents on the equine cervix under high magnification video-endoscopy. We hypothesized that polyethylene green microspheres 1 - …

The Seasonal Variations In Anthropometric And Performance Characteristics Of Elite Intercounty Gaelic Football Players, Richard Kelly, Kieran Collins

Articles

The seasonal variations in anthropometric and performance characteristics of elite inter county gaelic football players. J Strength Cond Res 32(12): 3475-3482, 2018-There is limited research assessing the anthropometric and performance variations in elite Gaelic football. The aim of this study was to assess the anthropometric and performance characteristics of an elite intercounty squad within a season. After ethical approval and informed consent, 26 participants were assessed at the start of preseason (November), after early in-season (January), and midseason (March). Measurements included stature, body mass, sum of 8 skinfold sites (ΣSkf8), estimated body fat percentage (bf%), squat jump (SJ) and countermovement …

Allergen Specific Immunotherapy And The Effect On Allergy Induced Asthma, Cord Tanner Landrum

Physician Assistant Scholarly Project Papers

Allergies are a major public health problem affecting over 300 million people worldwide (Asamoah et. al). An allergic response can occur when a harmless substance, such as tree pollen, is inhaled into the body and mistakenly identified as a harmful substance. Antibodies then bind to the allergen causing a release of chemicals that leads to symptoms such as nasal congestion, runny nose, itchy eyes or skin reactions. For some people, this reaction can also affect the lungs and airways leading to asthma symptoms.
