The surface roughness of titanium could regulate various cellular functions such as survival and growth. In the context of cell adhesion to materials, cell spreading and cell shape are also closely linked to various cellular functions. Previously, we found that Ti substrate with a 100-nm scale surface roughness reduced cell survival. However, effects of surface roughness on cell shape were not investigated. Herein, we quantified the initial adhesion behavior of osteoblasts on a Ti substrate with ~100 nm scale surfa [...]

Second-generation antipsychotics, have known metabolic side effects; specifically, clozapine is implicated in worsening or causing hyperglycemia, hypercholesterolemia and weight gain. Recently, there has been an increased interest in the safe use of clozapine in patients with diabetes. In March 2018, a 65-year-old female with a diagnosis of schizophrenia was admitted for inpatient hospitalization to a psychiatric hospital in Buffalo, NY for further stabilization after receiving two months of treatment at a comprehe [...]

Agitation is a common manifestation of acute brain injury. When not addressed, agitation can lead to slower recovery rates, including delayed admission to acute rehabilitation programs. Antipsychotics are commonly used to control agitation in acute brain injury in the ICU. However, there is no current consensus on the most "efficacious and safest strategy" for use of antipsychotics in acute TBI. Haloperidol is arguably the commonly used antipsychotic for agitation in ICU setting at present. Interestingly, there are [...]

Vanadium is an element that is widely distributed in Earth’s crust as well as in sea-water and ground-water reservoirs. Therefore, it exerts a great influence on the issues related to life and environment. Vanadium is utilized by several marine organisms. For example, there are vanadate-dependent haloperoxidases in algae and several bacteria, e.g., Azotobacter, use it for nitrogen fixation and bacterial reduction involves the conversion of vanadate to oxidovanadium (IV). The similarity between vanadate and phosphat [...]

Past research suggests that exercise is associated with improved working memory (WM) abilities, and that athletes have better executive functioning and WM skills than non-athletes. However, no studies to date have separated the effects of exercise from the effects of athletic participation when examining WM. This study had three primary goals: (1) to determine whether amateur college athletes have better auditory and visual WM than their non-athlete peers who exercise frequently and whether non-athlete frequent exe [...]

Physical inactivity is the fourth leading risk factor for global mortality and as such, it is critical that physical activity guidelines for health consider equitable access to physical activity opportunities for all, including those aged 65 years and older. The purpose of this study was to examine the intersections of attributes of older people (e.g. income, gender, age, health, physical activity) and attributes of the places they live (e.g. rurality, public transit, sidewalks, parks, community centre) to explain [...]

Most power plants produce electricity by converting a mechanical motion into alternating current (AC). Photovoltaic solar panels convert an electromagnetic flux of light into direct current (DC). In general, electric energy can be harvested from a flux in the environment or from a change of the environment itself. One can produce electricity from mechanical, chemical, thermal, electromagnetic (light), or another physical flux, or from a change of temperature, chemical composition, or a physical field: gravitationa [...]

A relativistic Wigner function for free Discrete Time Quantum Walks (DTQWs) on the square 2D space-time lattice is defined. The transport equation obeyed by the relativistic Wigner function is derived in terms of discrete derivatives and degenerates in the continuum limit into the transport equation obeyed by the Wigner function of 2D Dirac fermions. The first corrections to the continuous equation induced by the discreteness of the lattice are also determined and the similarities with non-quantum relativistic tran [...]

Falls have negative consequences for older adults, but falls can be reduced through interventions that target the reduction of fall risk factors. Cognitive behavioral education programs and therapeutic yoga are two interventions that have independently been used as a means to reduce the risk of falls. The purpose of this study was to determine if adding therapeutic yoga following an education intervention improved well known fall risk factors. Potential participants were recruited through a senior center for a 12-w [...]
