University faculty on student motivation to use medical education apps and barriers to their usage.

Objective: University teachers, who primarily provide guidance and advice to their students, can play a significant role in educational process transformation. As there is no particular e-learning framework, it is important to understand the factors and variables that may impact both its effective usage and further successful implementation. The current study aims to outline the influence of university faculty, and possible barriers preventing medical students from using apps for learning purposes.

Medical application usage traits by students in Greece.

Objective: Medical applications ("apps") can offer innovative educational capabilities, facilitating the acquisition of learning objectives and enhancing decision making. The present study aims at demonstrating the usage characteristics and relevant perceptions among students in seven medical schools in Greece.

Materials And Methods: A descriptive cross-sectional study was conducted through an online survey.

Towards ambient temperature-stable vaccines: the identification of thermally stabilizing liquid formulations for measles virus using an innovative high-throughput infectivity assay.

As a result of thermal instability, some live attenuated viral (LAV) vaccines lose substantial potency from the time of manufacture to the point of administration. Developing regions lacking extensive, reliable refrigeration ("cold-chain") infrastructure are particularly vulnerable to vaccine failure, which in turn increases the burden of disease. Development of a robust, infectivity-based high throughput screening process for identifying thermostable vaccine formulations offers significant promise for vaccine development across a wide variety of LAV products.

Sertoli cell proliferation in the fetal and neonatal rat testis: a continuous phenomenon?

Sertoli cell population kinetics, as evidenced by semi-quantitative immunolabeling for proliferating cell nuclear antigen (PCNA) and Ki-67, in developing Wistar rat male gonads of embryos and neonates [14.5 days post conception (dpc)-7 days post partum (dpp)], was investigated. Throughout the examined period a gradual increase of immunolabeled Sertoli cell number, associated with intense mitotic activity, was observed.

Evaluation of immunohistochemical markers of germ cells' proliferation in the developing rat testis: a comparative study.

Germ cells' proliferation during testicular organogenesis in Wistar rat embryos and neonates [14.5, 18.5, 20.

Combination of automated high throughput platforms, flow cytometry, and hierarchical clustering to detect cell state.

Background: This study examined whether hierarchical clustering could be used to detect cell states induced by treatment combinations that were generated through automation and high-throughput (HT) technology. Data-mining techniques were used to analyze the large experimental data sets to determine whether nonlinear, non-obvious responses could be extracted from the data.

Methods: Unary, binary, and ternary combinations of pharmacological factors (examples of stimuli) were used to induce differentiation of HL-60 cells using a HT automated approach.

Calmodulin-dependent protein kinase IV regulates hematopoietic stem cell maintenance.

The hematopoietic stem cell (HSC) gives rise to all mature, terminally differentiated cells of the blood. Here we show that calmodulin-dependent protein kinase IV (CaMKIV) is present in c-Kit+ ScaI+ Lin(-/low) hematopoietic progenitor cells (KLS cells) and that its absence results in hematopoietic failure, characterized by a diminished KLS cell population and by an inability of these cells to reconstitute blood cells upon serial transplantation. KLS cell failure in the absence of CaMKIV is correlated with increased apoptosis and proliferation of these cells in vivo and in vitro.

Helicobacter pylori in liquid culture: evaluation of growth rates and ultrastructure.

This study investigated the growth of Helicobacter (H.) pylori in Brucella broth supplemented with either IsoVitaleX (1% vol/vol), hemin (.01% wt.

Immunogenicity and safety of recombinant Helicobacter pylori urease in a nonhuman primate.

Groups of squirrel monkeys (Saimiri spp.), predetermined to be free of Helicobacter infections in the gastric mucosa, were immunized orally with 0.5-4.

An optimal design problem in rhythmometry.

A trigonometric regression model is assumed for a problem involving circadian rhythm exhibited by peak expiratory flow. Experimental designs are sought with a view to estimating a particular nonlinear function of the parameters. Both optimal and nonoptimal, but more practicable, designs are derived and their relative efficiencies are established.
