Enhancing Cataract Surgery Outcomes: Optimal Use Of Pre- And Post-Operative Eye Drops, Keith Skolnick M.D., Anu Valiaveedu

Mako: NSU Undergraduate Student Journal

Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Preventive Effects Of Quercetin On The Leaky Gut By Suppression Of Il-1beta-Induced Transcription Factors Involved In An Inflammatory Pathway In Colonic Epithelial Cells, Wannaporn Chayalak, Sumpun Thammacharoen, Chatsri Deachapunya, Sutthasinee Poonyachoti

The Thai Journal of Veterinary Medicine

Flavonol quercetin (Q), found in vegetables and fruits, demonstrates the most potent anti-inflammatory effect. The preventive effect and cellular mechanisms of Q (Q1, Q10, and Q100 µM) on IL-1β induced leaky gut via the signaling molecules of inflammatory pathway, NF-κB p65-iκB/or p38/ERK1/2/MLCK/phospho(p)-MLC were investigated in Caco-2 cells. The cytotoxic effect of Q was initially determined by MTT assay. Transepithelial electrical resistance (TER) and apical-to-basolateral fluorescein isothiocyanate-labeled dextran (FD-4) flux were used to determine paracellular permeability. The protein expression of signaling molecules was examined by Western blot analysis, and their target MLCK mRNA expression was determined using real-time PCR. All Q …

Affective Temperaments And Personality Traits In Couple Well-Being, Carmela Mento, Chiara La Barbiera, Maria Catena Silvestri, Maria Rosaria Anna Muscatello, Clemente Cedro, Antonio Bruno, Gianluca Pandolfo, Fiammetta Iannuzzo, Clara Lombardo

Journal of Mind and Medical Sciences

Background. The objective of this study is to establish the link between affective temperament traits and maladaptive personality traits, to verify whether the potential presence of elements related to emotional, affective and dysfunctional relational functioning can affect the couple satisfaction, modifying the well-being or discomfort condition. Materials and Methods. A data collection questionnaire was developed to investigate the factors associated with dysfunctional emotional, affective, and relational modes of functioning. The sample consisted of 473 subjects. Data were collected including the TEMPS-A questionnaire, The Dirty Dozen Italian Assessment and the Relationship Assessment Scale (RAS). Results. The findings of this study showed …

Effects Of Equine Interaction On Mutual Autonomic Nervous System Responses And Interoception In A Learning Program For Older Adults, Ann L. Baldwin, Lisa Walters, Barbara K. Rector, Ann C. Alden

People and Animals: The International Journal of Research and Practice

Equine-assisted learning (EAL) may improve the health of older adults, but scientific data are sparse. This study investigated whether people aged 55 and older show increased heart rate variability (HRV) during EAL and awareness of bodily sensations that are overall pleasant. Subjects (n = 24) participated in mindful grooming during which they slowed their breathing and brushed a horse while noticing sensations in their body and watching the horse’s reactions. The subject’s and horse’s HRV were recorded simultaneously before, during, and after mindful grooming. For control, the same subjects performed mindful grooming with a plush simulation horse. During exit …

Expression And Localization Of The 14-3-3 (Ywha) Protein Family Within Mammals, Neha Kumrah, Santanu De

Mako: NSU Undergraduate Student Journal

The 14-3-3 (YWHA) are a family of homologous, acidic, and highly conserved proteins expressed abundantly and ubiquitously in a wide array of organisms ranging from plants to animals, including humans, which regulate important cellular events. Within mammals, seven isoforms of 14-3-3 exist: β, γ, ε, ζ, η, τ, and σ (stratifin), each of which is encoded by a unique gene. Studies have shown similar expression patterns among mammalian species. The 14-3-3 proteins are commonly expressed and have proven to play critical roles in proper cellular localization, function, and homeostatic regulation. Numerous researchers have investigated the expression and localization patterns of …

A Comparison Of Lung Function Values Among A Scuba Diver Population And In Comparison To A Non-Diver Population, Gabriel C. Hutson, Jeremy D. Rentsch, Erin M. Eaton

Journal of the South Carolina Academy of Science

The purpose of this study was to investigate possible correlations between lung function values (PEF, IRV, ERV, and FVC) among a diver population, as well as in comparison to a non-diver population. Independent variables for both populations were biological sex, age, and weekly physical activity. Independent variables for the diver population were dive tenure, number of logged dives, certification level, and gas mixture used. A spirometry test was conducted to collect lung function values of both populations. Data from this study suggest a statistically significant relationship between diver and non-diver sex and FVC, diver age and ERV, diver sex and …

Effects Of A Form Of Equine-Facilitated Learning On Heart Rate Variability, Immune Function, And Self-Esteem In Older Adults, Ann L. Baldwin, Barbara K. Rector, Ann C. Alden

People and Animals: The International Journal of Research and Practice

Equine-facilitated learning (EFL) helps people access their immediate sensations and feelings because horses, as prey animals, are continually aware of their environment and provide instant feedback to human behaviors and emotions. We hypothesize that during EFL, older people become more aware of their bodily sensations and emotions, leading to increased heart rate variability (HRV), improved self-esteem (Rosenberg scale), and improved immune function. Twenty-four subjects (age > 55) participated in a single 15-minute EFL activity, Con Su Permiso, during which they focused on their bodily sensations and the responses of the horse as they moved toward and around the horse. Subjects …

Thermoregulatory Adaptations Following Sprint Interval Training, Jonathan E. Wingo, Charlie P. Katica, Svetlana Nepocatych, Andrew T. Del Pozzi, Greg A. Ryan

Journal of Human Performance in Extreme Environments

Traditional endurance training typically involves weeks of long-duration (60–90 min) exercise performed at a moderate to vigorous intensity. An alternative paradigm, sprint interval training, is characterized by multiple bouts of short-duration, high-intensity exercise. Similar fitness benefits from the two paradigms have been demonstrated, but whether sprint interval training—like traditional endurance training—induces heat acclimation remains unclear.

Purpose

To test the hypothesis that sprint interval training performed over six sessions results in measureable thermoregulatory and cardiovascular adaptations consistent with heat acclimation.

Methods

Seven untrained men [mean ± SD, 13 ± 5% body fat, 22 ± 3 y, 3.1 ± 0.3 L/min peak …

Space Operations In The Suborbital Space Flight Simulator And Mission Control Center: Lessons Learned With Xcor Lynx, Pedro Llanos, Christopher Nguyen, David Williams, Kim O. Chambers, Erik Seedhouse, Robert Davidson

Journal of Aviation/Aerospace Education & Research

This study was conducted to better understand the performance of the XCOR Lynx vehicle. Because the Lynx development was halted, the best knowledge of vehicle dynamics can only be found through simulator flights. X-Plane 10 was chosen for its robust applications and accurate portrayal of dynamics on a vehicle in flight. The Suborbital Space Flight Simulator (SSFS) and Mission Control Center (MCC) were brought to the Applied Aviation Sciences department in fall 2015 at Embry-Riddle Aeronautical University, Daytona Beach campus. This academic and research tool is a department asset capable of providing multiple fields of data about suborbital simulated flights. …
