BACKGROUND Genome-wide expression data of gene microarrays can be used to infer gene networks. At a cellular level, a gene network provides a picture of the modules in which genes are densely connected, and of the hub genes, which are highly connected with other genes. A gene network is useful to identify the genes involved in the same pathway, in a protein complex or that are co-regulated. In ...

BACKGROUND Dabbing is an emerging method of marijuana ingestion. However, little is known about dabbing owing to limited surveillance data on dabbing. OBJECTIVE The aim of the study was to analyze Google search data to assess the scope and breadth of information seeking on dabbing. METHODS Google Trends data about dabbing and related topics (eg, electronic nicotine delivery system [ENDS], a...

UNLABELLED With the rapid increase of omics data, correlation analysis has become an indispensable tool for inferring meaningful associations from a large number of observations. Pearson correlation coefficient (PCC) and its variants are widely used for such purposes. However, it remains challenging to test whether an observed association is reliable both statistically and biologically. We pres...

The urchin Diadema antillarum Philippi (Echinodermata: Echinoidea) was extremely rare to absent from reefs throughout Jamaica during much of the 1980s and part of the 1990s following a Caribbean wide mortality event. This survey was conducted in 2007 to assess their distribution on the western forereef of Discovery Bay, Jamaica. Mean urchin densities of 3.93 ± 3.4 m -2 (mean ± SD) are the highe...

Laboratory-based simulators afford many advantages for studying physiology and biomechanics; however, they may not perfectly mimic wheelchair propulsion over natural surfaces. The goal of this study was to compare kinetic and temporal parameters between propulsion overground on a tile surface and on a dynamometer. Twenty-four experienced manual wheelchair users propelled at a self-selected spee...

The purpose of this study was to examine the relationships between measurements of lumbar lordosis, pelvic tilt, and abdominal muscle performance during normal standing. In addition, the reliability of the measurements used in this study was examined. Measurements of lumbar lordosis, pelvic tilt, and abdominal muscle performance were taken of 31 healthy adults aged 20 to 33 years. Each measurem...

Objective. This study explores the relationship between depressive symptoms, as measured by the PHQ-9 depression screen and blood glucose levels among patients with diabetes enrolled in Gold Choice, a Medicaid managed care program for individuals with mental illness and/or substance abuse. Methods. The PHQ-9 was mailed to 454 Gold Choice members and a questionnaire was mailed to their physician...

Enzyme profiles of eight Flavobacterium species and one Sphingobacterium species were compared after using a two-dimensional fluorescence technique. Enzyme contents and corresponding activities were rapidly determined for whole-cell preparations after incubation with a mixture of preselected fluorogenic substrates. A two-dimensional fluorescence spectrum of the resulting product mixture, measur...

(i) The number of cases, n, on which the regression is based. (ii) The total number of variables, dependent and independent, in the regression, ðkþ 1Þ. (iii) The number of independent variables in the regression, k. (iv) The means of all kþ 1 variables in the regression, both the independent variables ðx1; x2; . . . ; xkÞ and the dependent variable ðyÞ, which is the ðkþ 1Þth variable: i.e., x1;...

This study evaluated asymmetry of weight bearing on the lower limbs and the association between percentage weight bearing asymmetry (PWBA) and functional ambulation performance in ambulant stroke survivors. Participants were 53 stroke survivors (male = 35, female = 18) aged 40-86 years (mean=58.87; SD=9.21years) with hemiparesis. Weight bearing through the lower limbs in standing was assessed b...
