We review the use of numerical and computational models to explore deep brain stimulation for Parkinson’s disease (DBS PD). It is a review for the modeler and those interested in PD DBS modelling methods and their value. The main model categories of active fiber, mean field, driving force, and volume of tissue activated are described as well as many modelling techniques. We give the basic requirements for a DBS PD model and current theories of DBS mechanism of action, PD etiology, and movement selection. The emphas [...]

Homeopathy is often attacked with claims of not being evidence-based or for the implausible nature of its major principles of dilution/potentization and/or the similars (“similia similibus curentur”). However, these statements have already been falsified on the experimental ground, besides being incorrect on an epistemological level. Here we provide an updated appraisal of the scientific approach to the principle of Similars and homeopathy, focusing on laboratory models. After a brief historical introdu [...]

Flavonoids are phytochemicals (polyphenols) of plant origin. They can trap free oxygen radicals generated by mitochondria and other electronic transport chains, thereby inhibiting inflammatory and carcinogenic changes in vivo and in vitro. Why the body requires these compounds for the well-being of the organism and the maintenance of human health remains unclear. However, a deficit of flavonoids could lead to molecular malfunctions in cells, organelles, and macromolecules. This manuscript describes the occurrence a [...]

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 [...]

Hypnosis is a modified state of consciousness widely used to decrease pain perception in research protocols and clinical practice. In recent decades, hypnosis has been increasingly proposed to patients to re-engage their resources and capacities to modulate pain and emotional distress and to improve their treatment and recovery of well-being. Neuroimaging research helps clinicians to understand better how hypnosis works in terms of brain modulation. Hypnotic suggestions dramatically influence the self and environme [...]

In this study, we synthesized Pt-Rh nanowires (NWs) through chemical reduction of metallic precursors using formic acid at room temperature, excluding the use of surfactants, templates, or stabilizing agents. These NWs were supported on two substrates: carbon (Vulcan XC-72R) and carbon modified with tin oxide (SnO2) via the sol-gel method (10 wt.% SnO2). We explored the electroactivity of Pt/SnO2/C, Pt-Rh/C, Pt-Rh/SnO2(commercial)/C (commercial SnO2), and Pt-Rh/SnO2/C NWs toward electrochemical oxidation of ethanol [...]

Infection with parvovirus B19 is common, with up to 55% of adults showing seropositive evidence of prior infection. Clinical disease can occur due to acute infection, chronic persistent viremia, rarely secondary infection, or possibly viral reactivation of latent virus. The clinical presentation of primary infection depends on age, the presence of a hematologic condition, and immune status. We report a renal transplant recipient who developed transfusion dependent anemia refractory to erythropoietin that responded [...]

The use of the dry reforming of methane (DRM) to convert the two principal greenhouse gases, methane and carbon dioxide, to syngas (a mixture of H2 and CO) has attracted increasing attention in recent years. However, the DRM reaction suffers from the twin disadvantages of carbon deposition and sintering, so a highly efficient and robust catalyst with superior anti-deactivation properties is required. One way to meet this need is to incorporate active metals into crystalline oxides, such as perovskite. In this paper [...]

Ellagic acid (EA) is a polyphenol found in grapes, pomegranates, walnuts, etc. exhibits anti-cancer properties. The current study was conducted to understand the radiosensitizing role of EA on HeLa cells. Monotherapy of EA and radiation was initially studied on HeLa cells. The addition of EA before the radiation treatment subsequently made DNA more susceptible to damage thereby developing DNA beaks, which are known to be lethal for cell survival. This was evaluated by performing comet and γ-foci formation ass [...]

Infections are a common cause of morbidity and mortality in solid organ transplantation (SOT) recipients. Procalcitonin (PCT) has garnered attention as an inflammatory marker that has been shown to be a valuable marker for early identification of systemic bacterial infection. However, interpretation of PCTs value in the different types of infections, transplanted organs, and post-operative courses can be challenging. We review the role of PCT in the management of infections in SOT recipients. First, the PCT level c [...]

This paper aims to introduce a relatively novel approach for Hypnosis to treat Depersonalization-derealization Disorder (DPRD). Depersonalization is conceptualized as a disrupted interoceptive process disorder. Based on this conceptualization, Hypnotic intervention is tailored to counter the flawed process. It is exemplified by a case of a young man suffering from depersonalization disorder who couldn't bear looking at himself in the mirror. The hypnotic intervention used in this case is then explained by predictiv [...]

Many studies have demonstrated that HLA-DR, HLA-DQ and HLA-DP matching at the eplet level reduces allograft rejection and improves transplant outcome. Such studies have examined the eplet effect for the individual class II loci, but until now little attention has been given to so-called interlocus class II eplets shared between HLA-DR, HLA-DQ and/or HLA-DP alleles. This report summarizes current information about antibody-verified interlocus class II eplets. It describes a structural modeling method to determine po [...]
