REVIEW
Marie Carmela M Lapitan, June D Cody, Atefeh Mashayekhi
BACKGROUND: Urinary incontinence is a common and potentially debilitating problem. Stress urinary, incontinence as the most common type of incontinence, imposes significant health and economic burdens on society and the women affected. Open retropubic colposuspension is a surgical treatment which involves lifting the tissues near the bladder neck and proximal urethra in the area behind the anterior pubic bones to correct deficient urethral closure to correct stress urinary incontinence...

Electrospray ionization (ESI) is widely used in liquid chromatography coupled to mass spectrometry (LC-MS) for the analysis of biomolecules. However, the ESI process is still not completely understood and it is often a matter of trial and error to enhance ESI efficiency and hence the response of a given set of compounds. In this work we performed a systematic study of the ESI response of 14 amino acids that were acylated with organic acid anhydrides of increasing chain length and with polyethylene glycol (PEG) changing certain physicochemical properties in a predictable manner...

BACKGROUND: In cardiomyocytes from patients with hypertrophic cardiomyopathy, mechanical dysfunction and arrhythmogenicity are caused by mutation-driven changes in myofilament function combined with excitation-contraction (E-C) coupling abnormalities related to adverse remodeling. Whether myofilament or E-C coupling alterations are more relevant in disease development is unknown. Here, we aim to investigate whether the relative roles of myofilament dysfunction and E-C coupling remodeling in determining the hypertrophic cardiomyopathy phenotype are mutation specific...

Pain is an unwelcome sleep partner. Pain tends to erode sleep quality and alter the sleep restorative process in vulnerable patients. It can contribute to next-day sleepiness and fatigue, affecting cognitive function. Chronic pain and the use of opioid medications can also complicate the management of sleep disorders such as insomnia (difficulty falling and/or staying asleep) and sleep-disordered breathing (sleep apnea). Sleep problems can be related to various types of pain, including sleep headache (hypnic headache, cluster headache, migraine) and morning headache (transient tension type secondary to sleep apnea or to sleep bruxism or tooth grinding) as well as periodic limb movements (leg and arm dysesthesia with pain)...

EDITORIAL
María José Gálvez-Ruiz
In this review classical studies on insoluble liquid monolayers formed by proteins are examined and compared. It has been focused the attention on the information that it is possible to obtain from the π-a isotherms recorded by compression of the monolayers. In recent decades new techniques have developed, mainly microscopy, that provide valuable information on the behavior and structure of fluid films. However, frequently the data are difficult to interpret and require a previous thermodynamic study of them on the basis of the surface tension (or surface pressure) as a function of the molecular area measurement...

BACKGROUND: Headache is a common disorder which may lead to substantial socio-economic loss. Treatment options include self-management strategies, medication and physiotherapy. Physiotherapists need to be able to screen for the presence of migraine and tension-type headache (TTH), so they can adjust their treatment strategies to the type of headache. A quick screening questionnaire to recognize migraine and TTH in the physiotherapy practice is needed. OBJECTIVE: The aim of this study was to create a headache screening questionnaire based on the ICHD-3 beta criteria for migraine and TTH, and to establish its content and criterion validity...

From a microbiological perspective, sourdough is to be considered as a specific and stressful ecosystem, harboring yeasts and lactic acid bacteria (LAB), that is used for the production of baked goods. With respect to the metabolic impact of the sourdough microbiota, acidification (LAB), flavor formation (LAB and yeasts), and leavening (yeasts and heterofermentative LAB species) are most noticeable. Three distinct types of sourdough fermentation processes can be discerned based on the inocula applied, namely backslopped ones (type 1), those initiated with starter cultures (type 2), and those initiated with a starter culture followed by backslopping (type 3)...

This work presents some important issues and topics related to possible extraction of 2-phenylethanol (PEA) from aqueous phase "in situ" during the biosynthesis. It consist of a series of experimental phase equilibrium measurements in binary and ternary systems. Ionic liquids (ILs) are an important new media for imaging and sensing applications because of their solvation property, thermal stability and negligible vapor pressure. However, complex procedures and non-miscibility with water are often required in PEA extraction...

Using molecular dynamics simulations, we study the effects of Mo and S atomic vacancies and different temperatures on the tensile properties of single-walled MoS2 nanotubes through a series of tensile tests. Both armchair and zigzag MoS2 nanotubes under uniaxial tensions show phase transitions. Two types of Mo-S bonds play different roles in this phase transition of MoS2 nanotubes. Moreover, the influences of Mo and S atomic vacancies and temperature on the Young's modulus, ultimate strength and fracture strain of single-walled MoS2 nanotubes are investigated systematically...

Acute O2 sensing is a fundamental property of cells in the peripheral chemoreceptors, e.g. glomus cells in the carotid body (CB) and chromaffin cells in the adrenal medulla (AM), and is necessary for adaptation to hypoxia. These cells contain O2 -sensitive ion channels, which mediate membrane depolarization and transmitter release upon exposure to hypoxia. However, the mechanisms underlying the detection of changes in O2 tension by cells are still poorly understood. Recently, we suggested that CB glomus cells have specific metabolic features that favour the accumulation of reduced quinone and the production of mitochondrial NADH and reactive oxygen species during hypoxia...

The body wall of starfish is composed of magnesium calcite ossicles connected by collagenous tissue and muscles and it exhibits remarkable variability in stiffness, which is attributed to the mechanical mutability of the collagenous component. Using the common European starfish Asterias rubens as an experimental animal, here we have employed a variety of techniques to gain new insights into the structure of the starfish body wall. The structure and organisation of muscular and collagenous components of the body wall were analysed using trichrome staining...
