Application Of A Balance Training Program In A Patient With Charcot Marie Tooth Disease: A Case Report

Charcot Marie Tooth Disease (CMT) is the most common progressive inherited neurological disease. Proteins in the myelin sheath of both motor and sensory nerves become damaged, resulting in muscle atrophy and reduced sensation. Patients experience difficulty with gait, balance, and independence with ADLs. The RUSK Modified Romberg Program (MRP) is a balance program used for patients with neurological pathologies. There is minimal research on the effectiveness of the RUSK MRP in patients with CMT. The purpose of this case report was to determine the effectiveness of the RUSK MRP in order to improve balance and reduce risk of falls in a patient with CMT.https://dune.une.edu/pt_studcrposter/1057/thumbnail.jp

Holography and holomorphy in quantum field theories and gravity

This Ph.D. thesis deals with the application of complex analysis and holographic methods to study both the perturbative and the non-perturbative regimes of Quantum Field Theories and Gravity. Although Gravity does not admit a full quantum picture, its classical description is fine at tree level and it becomes useful for studying strongly coupled gauge theories through the gauge/gravity correspondence. We first study a generalization of the BCFW on-shell recursion relation, which allows us to characterize the tree-level scattering amplitudes of theories of massless particles in a fashion completely detached from the usual Feynman representation. This permits proposing a novel approach to the construction of theories which, despite being only valid at tree level and just for theories of massless particles, returns in a very simple manner some powerful facts, well-known from the traditional Lagrangian analysis. Then we focus on obtaining several new supergravity solutions dual to supersymmetric gauge theories with fundamental matter (flavor) in the Veneziano limit. These solutions must incorporate the backreaction of an infinite number of flavor branes. We choose to smear these branes in order to find analytical solutions. We find fully regular solutions describing the strongly coupled dynamics of flavor in the ABJM theory and in a SQCD-like theory. For the former, the solution has an AdS factor, and many checks can be done confirming that the supergravity solution is a faithful dual. For the latter, some checks can also be done, and more interestingly, phenomenological applications that might be relevant for Beyond-the-Standard-Model Physics can be found. Finally, we illustrate other uses of the gauge/gravity correspondence by finding supergravity solutions dual to theories exhibiting a Kutasov duality and SQCD-like theories in two and three dimensions

Reactive Oxygen Species at High Altitude (Hypobaric Hypoxia) on the Cardiovascular System

Reactive oxygen species (ROSs) play important physiological and physiopathological roles in the cardiovascular system. An imbalance between ROS and antioxidants, termed oxidative stress, can contribute to endothelial dysfunction and cardiovascular remodeling. ROSs have been demonstrated to be increased and to regulate the following main pulmonary vasculature changes that occur at high altitude (hypobaric hypoxia): hypoxic pulmonary vasoconstriction (HPV), pulmonary hypertension, right ventricular hypertrophy (RVH), and ultimately, cardiac failure. Thus, ROS increases are a public health concern for the increasing number of people living or working at high altitudes. ROSs trigger the activation of different metabolic signaling pathways that alter the activity of redox-sensitive transcription factors and translational signals. Consequently, we provide a comprehensive review of the literature on the main factors, sources, and mechanisms of action of ROS and their effects on the cardiovascular system under hypobaric hypoxic conditions. Although ROS generation is a normal physiological activity, under hypobaric hypoxia (high altitude) conditions, ROS levels are elevated. The principal sources of ROS are nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-4 (NOX4) in the vascular system and NOX2 in cardiac tissue. Thus, the information presented in this review provides a broad view of the relationship between ROS and hypoxia

A reexamination of the effective fine structure constant of graphene, as measured in graphite

We present a refined and improved study of the influence of screening on the effective fine structure constant of graphene, $\alpha^*$, as measured in graphite using inelastic x-ray scattering. This follow-up to our previous study [J. P. Reed, et al., Science 330, 805 (2010)] was carried out with two times better energy resolution, five times better momentum resolution, and improved experimental setup with lower background. We compare our results to RPA calculations and evaluate the relative importance of interlayer hopping, excitonic corrections, and screening from high energy excitations involving the $\sigma$ bands. We find that the static, limiting value of $\alpha^*$ falls in the range 0.25 to 0.35, which is higher than our previous result of 0.14, but still below the value expected from RPA. We show the reduced value is not a consequence of interlayer hopping effects, which were ignored in our previous analysis, but of a combination of excitonic effects in the $\pi \rightarrow \pi^*$ particle-hole continuum, and background screening from the $\sigma$-bonded electrons. We find that $\sigma$-band screening is extremely strong at distances of the order of a few nm, and should be highly effective at screening out short-distance, Hubbard-like interactions in graphene, as well as other carbon allotropes.Comment: 23 pages, 5 figure

Seasonal phenology of the major insect pests of quinoa (Chenopodium quinoa willd.) and their natural enemies in a traditional zone and two new production zones of Peru

Over the last decade, the sown area of quinoa (Chenopodium quinoa Willd.) has been increasingly expanding in Peru, and new production fields have emerged, stretching from the Andes to coastal areas. The fields at low altitudes have the potential to produce higher yields than those in the highlands. This study investigated the occurrence of insect pests and the natural enemies of quinoa in a traditional production zone, San Lorenzo (in the Andes), and in two new zones at lower altitudes, La Molina (on the coast) and Majes (in the "Maritime Yunga" ecoregion), by plant sampling and pitfall trapping. Our data indicated that the pest pressure in quinoa was higher at lower elevations than in the highlands. The major insect pest infesting quinoa at high densities in San Lorenzo was Eurysacca melanocampta; in La Molina, the major pests were E. melanocampta, Macrosiphum euphorbiae and Liriomyza huidobrensis; and in Majes, Frankliniella occidentalis was the most abundant pest. The natural enemy complex played an important role in controlling M. euphorbiae and L. huidobrensis by preventing pest resurgence. The findings of this study may assist quinoa producers (from the Andes and from regions at lower altitudes) in establishing better farming practices in the framework of integrated pest management
