BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life threatening condition resulting from excessive ovarian stimulation. Reported incidence of moderate to severe OHSS ranges from 0.6% to 5% of in vitro fertilization (IVF) cycles. The factors contributing to OHSS have not been completely explained. The release of vasoactive substances secreted by the ovaries under human chorionic gonadotrophin (hCG) stimulation may play a key role in triggering this syndrome...

BACKGROUND: Post-dural puncture headache (PDPH) is a relatively common complication of lumbar punctures for spinal anesthesia or neurologic diagnosis. For many years, a high number of drugs has been evaluated to treat PDPH, yet there is a minority to prevent this complication. The lateral decubitus position instead of sitting position during lumbar puncture has become an interesting approach because of its feasibility and patient satisfaction. OBJECTIVES: In this meta-analysis we hypothesized that lateral decubitus position is an effective manner to prophylactically reduce the incidence of PDPH...

BACKGROUND: Spinal cord stimulation (SCS) has been successfully used to treat chronic intractable pain for over 40 years. Successful clinical application of SCS is presumed to be generally dependent on maximizing paresthesia-pain overlap; critical to achieving this is positioning of the stimulation field at the physiologic midline. Recently, the necessity of paresthesia for achieving effective relief in SCS has been challenged by the introduction of 10 kHz paresthesia-free stimulation...

BACKGROUND: Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) have sufficient scientific support for their use as tissue protectors. Preliminary studies suggest that their angiotensin-II type 2 receptor (AT2R)-blocking properties have a beneficial profile in the treatment of neuropathic pain. OBJECTIVES: The purpose of the current study was to quantify the extent of the somatosensory effects of ACEI and ARB in cancer patients with chemotherapy-induced peripheral neuropathy...

This paper proposes a regional competitive governance and management of response and recovery from disasters. It presents problems experienced in major disasters, analyzes the failures, and suggests how a competitive system that relies on private and volunteer regional leaders, personnel, and capital can improve preparation, response and recovery efforts over the existing government system. A Public Choice approach is adopted to explain why government often fails, and how regional governance may be socially more efficient than the existing federal- state-local funded and managed disaster system...

OBJECTIVES: Perampanel, a selective, noncompetitive AMPA receptor antagonist, is indicated as adjunctive therapy for the treatment of partial seizures with or without secondarily generalized seizures and primary generalized tonic-clonic seizures in patients with epilepsy aged 12years and older. In vitro studies and Phase I trials indicate that perampanel is metabolized almost exclusively by CYP3A, with an elimination half-life (t1/2) averaging approximately 105h. Understanding of pharmacokinetic (PK) interactions-enzyme inhibition or induction-and anticipating their occurrence are important for management of patients with epilepsy...

Chain event graphs are a graphical representation of a statistical model derived from event trees, previously applied to cohort studies but not to case-control studies. We apply the chain event graph framework to a Yorkshire case-control study of childhood type I diabetes, to examine four exposure variables associated with the mother, three of which are fully observed (her school-leaving-age, amniocenteses during pregnancy and delivery type) and one with missing values (her rhesus factor), while incorporating previous type I diabetes knowledge...

The intrinsic stochasticity of gene expression can give rise to large fluctuations and rare events that drive phenotypic variation in a population of genetically identical cells. Characterizing the fluctuations that give rise to such rare events motivates the analysis of large deviations in stochastic models of gene expression. Recent developments in non-equilibrium statistical mechanics have led to a framework for analyzing Markovian processes conditioned on rare events and for representing such processes by conditioning-free driven Markovian processes...

G protein-coupled receptor (GPCR) association is an emerging paradigm with far reaching implications in the regulation of signalling pathways and therapeutic interventions. Recent super resolution microscopy studies have revealed that receptor dimer steady state exhibits sub-second dynamics. In particular the GPCRs, muscarinic acetylcholine receptor M1 (M1MR) and formyl peptide receptor (FPR), have been demonstrated to exhibit a fast association/dissociation kinetics, independent of ligand binding. In this work, we have developed a spatial kinetic Monte Carlo model to investigate receptor homo-dimerisation at a single receptor resolution...

Bacteria communicate with one another using chemical signal molecules called autoinducers, and the most prevalent autoinducers used by Gram-negative bacteria are N-acylated homoserine lactones (AHLs). However, AHLs are hardly detected in Shewanella baltica, the specific spoilage organism of Pseudosciaena crocea. In this study, we applied ultra-high-performance liquid chromatography coupled to triple quadrupole tandem mass spectrometry (UHPLC-QqQ-MS/MS) to determine AHLs. This method enabled the quantification of up to 11 AHLs within 5...

Improved data visualization will be a significant tool to enhance cluster analysis. In this paper, an information-theoretic-based method for cluster visualization using self-organizing maps (SOMs) is presented. The information-theoretic visualization (IT-vis) has the same structure as the unified distance matrix, but instead of depicting Euclidean distances between adjacent neurons, it displays the similarity between the distributions associated with adjacent neurons. Each SOM neuron has an associated subset of the data set whose cardinality controls the granularity of the IT-vis and with which the first- and second-order statistics are computed and used to estimate their probability density functions...

Bing Su, Xiaoqing Ding, Changsong Liu, Hao Wang, Ying Wu
Feature space transformation (FST) techniques have been widely studied for dimensionality reduction in vector-based feature space. However, these techniques are inapplicable to sequence data because the features in the same sequence are not independent. In this paper, we propose a method called max-min inter-sequence distance analysis (MMSDA) to transform features in sequences into a low-dimensional subspace such that different sequence classes are holistically separated. To utilize the temporal dependencies, MMSDA first aligns features in sequences from the same class to an adapted number of temporal states and then constructs the sequence class separability based on the statistics of these ordered states...

BACKGROUND: Many of the world's population have hearing loss in one ear; current statistics indicate that up to 10% of the population may be affected. Although the detrimental impact of bilateral hearing loss, hearing aids, and cochlear implants upon music appreciation is well recognized, studies on the influence of single-sided deafness (SSD) are sparse. PURPOSE: We sought to investigate whether a single-sided hearing loss can cause problems with music appreciation, despite normal hearing in the other ear...
