    Abstract The effect of wrist deviation on grip and pinch strength was evaluated in 12 normal right-handed adults. Wrist positions of neutral, maximal ulnar (average, 41 degrees), and maximal radial deviation (average, 26 degrees) were held in short-arm casts while grip and key and tip pinch were measured. Wrist position was neutral with respect to flexion and extension. A highly significant effect of wrist deviation on grip strength was found (p < 0.0001). The effect on pinch strength was not statistically significant. Wrist deviation deformities arise in several clinical situations, such as radial clubhand and malunions of the distal radius. A loss of grip strength was found in radial deviation in this study. This would support 1 of the premises for surgical correction of such deviation by centralization or osteotomy.

    Abstract We describe here a method for optimizing the use of polychromatic flow cytometry (with up to 17 fluorochromes simultaneously) in surface and intracellular staining of human T lymphocytes. We will highlight and discuss how to procedurally optimize key steps in the experimental process before an intracellular cytokine staining assay protocol is finalized. These include but are not limited to the titration of monoclonal antibodies, use of a dead-cell discriminator and 'dump' channel, selection of a cytokine secretion inhibitor, selection of fixation and permeabilization reagents, and inclusion of compensation controls. Building on this basic protocol, we then establish a polychromatic assay designed to detect five separate functions of T lymphocytes (production of three cytokines and one chemokine, and degranulation) while simultaneously identifying multiple surface markers on the responding cells.

    Abstract Background: Recent consensus guidelines recommend pregabalin as a first-tier treatment for painful diabetic peripheral neuropathy (DPN). We evaluated the efficacy of pregabalin 600 mg/d (300 mg dosed BID) versus placebo for relieving DPN-associated neuropathic pain, and assessed its safety using objective measures of nerve conduction (NC).
    Methods: In this randomized, double-blind, placebo-controlled trial, the primary efficacy measure was endpoint mean pain score (MPS) from daily pain diaries (11-point scale). NC velocity and sensory and motor amplitudes were assessed at baseline, endpoint, and end of follow-up (2 weeks post-treatment). At each timepoint, the median-motor, median-sensory, ulnar-sensory, and peroneal-motor nerves were evaluated. Secondary efficacy measures included weekly MPS and proportion of responders (patients achieving >or=50% reduction in MPS from baseline to endpoint). After 1-weeks' dosage escalation, pregabalin-treated patients received 300 mg BID for 12 weeks.
    Results: Eighty-two patients received pregabalin and 85 placebo. Mean durations were 10 years for diabetes and approximately 5 years for painful DPN. Pregabalin-treated patients had lower MPS than controls (mean difference, -1.28; p <.001). For all four nerves, 95% CIs for median differences in amplitude and velocity from baseline to endpoint and baseline to follow-up included 0 (ie, no significant difference vs. placebo). Significant pain improvement among pregabalin-treated patients was evident at week 1 and sustained at every weekly timepoint. More pregabalin-treated patients (49%) than controls (23%) were responders (p <.001).
    Conclusion: Pregabalin 600 mg/d (300 mg BID) effectively reduced pain, was well tolerated, and had no statistically significant or clinically meaningful effect on NC in patients with painful DPN.

    Abstract Quantum dots (QD) are fluorescent nanocrystals that are highly useful in imaging and flow cytometric analyses. During routine use of monoclonal antibody conjugates of QD, we have occasionally seen partial or total loss of fluorescence when using certain lots of fixative solutions. We hypothesized that a low level contamination with heavy metal cations was responsible, since low level metal contaminants are not uncommon in formalin solutions. By titrating known concentrations of heavy metal cations into staining solutions, we found that millimolar concentrations of ferrous and zinc ions, and as low as 50 nanomolar cupric ions, completely eliminated QD fluorescence. By mass spectroscopic quantification of metals in commercial fixative solutions previously shown to perform poorly or well with regard to QD fluorescence, we confirmed that the presence of copper in solution was correlated with poor performance. Notably, prior addition of EDTA to chelate the divalent cations in these solutions prevented the inhibition of QD fluorescence. Finally, the copper-induced loss of QD fluorescence is irreversible: cells labeled with QD are highly fluorescent and can be rendered nonfluorescent by the addition of cupric sulfate, even after washing extensively. Indeed, these cells can then be successfully stained with other QD reagents, providing a method for immunofluorescence restaining of cells without contaminating fluorescence from the first stain.

    Abstract We examined the anatomic and biomechanical adequacy of the central quadriceps tendon as an alternative graft source for anterior cruciate ligament reconstruction. Morphometry was performed on 15 preserved and 6 fresh-frozen specimens. Biomechanical testing was performed on the six fresh-frozen specimens. We initially used a triple suture through the tendon construction, and then clamping directly on the tendon. Morphometry yielded the following measurements: length, 6.1 +/- 1.0 cm; width, 2.7 cm (range, 2.1 to 3.7); and thickness, 7 mm (range, 6.4 to 7.8). The thickness was 1.8 times that of the patellar tendon. Biomechanical testing showed that suture failure occurred at 692 +/- 181 N, and tendon failure occurred at 1075 +/- 449 N. The load to tendon failure was 1.36 times that of a comparable-width patellar tendon graft, although the difference was not statistically significant. The failure mode was primarily through partial or complete tendinous avulsion, with only one specimen failing at midsubstance. These findings show the central quadriceps graft is of sufficient size and strength to be used for anterior cruciate ligament reconstruction.

    Abstract 1. Global improvement data from five double-blind clinical trials of gabapentin as add-on therapy in patients with epilepsy were reviewed to assess the effects of gabapentin on mood. 2. One hundred and ninety-four (46%) of 423 gabapentin-treated patients reported improvements in general well-being as compared with 79 (29%) of the 271 placebo-treated patients. 3. Findings support anecdotal reports of improved affective status among patients taking gabapentin and suggest that the study of gabapentin in psychiatric populations may be warranted.

    Abstract Motivation: Cell populations are never truly homogeneous; individual cells exist in biochemical states that define functional differences between them. New technology based on microfluidic arrays combined with multiplexed quantitative polymerase chain reactions now enables high-throughput single-cell gene expression measurement, allowing assessment of cellular heterogeneity. However, few analytic tools have been developed specifically for the statistical and analytical challenges of single-cell quantitative polymerase chain reactions data.
    Results: We present a statistical framework for the exploration, quality control and analysis of single-cell gene expression data from microfluidic arrays. We assess accuracy and within-sample heterogeneity of single-cell expression and develop quality control criteria to filter unreliable cell measurements. We propose a statistical model accounting for the fact that genes at the single-cell level can be on (and a continuous expression measure is recorded) or dichotomously off (and the recorded expression is zero). Based on this model, we derive a combined likelihood ratio test for differential expression that incorporates both the discrete and continuous components. Using an experiment that examines treatment-specific changes in expression, we show that this combined test is more powerful than either the continuous or dichotomous component in isolation, or a t-test on the zero-inflated data. Although developed for measurements from a specific platform (Fluidigm), these tools are generalizable to other multi-parametric measures over large numbers of events.
    Availability: All results presented here were obtained using the SingleCellAssay R package available on GitHub (http://github.com/RGLab/SingleCellAssay).

    Abstract Amine-reactive dyes, also known as LIVE/DEAD fixable dead cell stains, are a class of viability dyes suitable for identifying dead cells in samples that will be fixed. These dyes cross the cell membranes of dead cells, and react with free amines in the cytoplasm. Live cells exclude these dyes because their cell membranes are intact, and free dye is washed away after staining. Notably, the reaction is irreversible; therefore, when cells are fixed and permeabilized (as with intracellular staining procedures), the bound dye remains associated with the dead cells (unlike other viability dyes). Since amine-reactive dyes are fluorescent when excited by lasers, dead cells can be identified by flow cytometry. This unit describes procedures, troubleshooting, and outcomes for using the two most commonly used amine-reactive dyes, ViViD and Aqua Blue.

    Abstract Highly multiplexed, single-cell technologies reveal important heterogeneity within cell populations. Recently, technologies to simultaneously measure expression of 96 (or more) genes from a single cell have been developed for immunologic monitoring. Here, we report a rigorous, optimized, quantitative methodology for using this technology. Specifically: we describe a unique primer/probe qualification method necessary for quantitative results; we show that primers do not compete in highly multiplexed amplifications; we define the limit of detection for this assay as a single mRNA transcript; and, we show that the technical reproducibility of the system is very high. We illustrate two disparate applications of the platform: a "bulk" approach that measures expression patterns from 100 cells at a time in high throughput to define gene signatures, and a single-cell approach to define the coordinate expression patterns of multiple genes and reveal unique subsets of cells.
