Cochlear implants operate within a bony channel of the cochlea, bathed in a fluid known as the perilymph. The perilymph is a complex fluid containing ions and proteins, which are known to actively interact with metallic electrodes. To improve our understanding of how cochlear implant performance varies in preclinical in vivo studies in comparison to human trials and patient outcomes, the protein composition (or perilymph proteome) is needed. Samples of perilymph were gathered from feline and guinea pig subjects and analyzed using liquid chromatography with tandem mass spectrometry (LC-MS/MS) to produce proteomes and compare against the recently published human proteome...

India's Kumbh Mela remains the world's largest and longest mass gathering. The 2013 event, where participants undertook a ritual bath, hosted over 70 million Hindu pilgrims during 55 days on a 1936 hectare flood plain at the confluence of the Yamuna and Ganga Rivers. On the holiest bathing days, the population surged. Unlike other religious, cultural, and sports mass gatherings, the Kumbh Mela's administration cannot estimate or limit the participant number. The event created serious and uncommon public health challenges: initiating crowd safety measures where population density and mobility directly contact flowing bodies of water; providing water, sanitation, and hygiene to a population that frequently defecates in the open; and establishing disease surveillance and resource use measures within a temporary health delivery system...

Chimney swifts (Chaetura pelagica) are highly manoeuvrable birds notable for roosting overnight in chimneys, in groups of hundreds or thousands of birds, before and during their autumn migration. At dusk, birds gather in large numbers from surrounding areas near a roost site. The whole flock then employs an orderly, but dynamic, circling approach pattern before rapidly entering a small aperture en masse We recorded the three-dimensional trajectories of ≈1 800 individual birds during a 30 min period encompassing flock formation, circling, and landing, and used these trajectories to test several hypotheses relating to flock or group behaviour...

The gas-phase structural modifications induced by the oxidation of methionine of two peptides of reverse sequence, methionine-valine (Met-Val) and valine-methionine (Val-Met), have been studied by mass-selected infrared multiple photon dissociation (IRMPD) spectroscopy in the 800-2000 cm-1 fingerprint range at the Centre Laser Infrarouge d'Orsay (CLIO) free electron laser facility. Oxidation has been achieved by •OH radicals generated by γ-radiolysis. IRMPD spectra were interpreted by static and harmonic DFT calculations and Born-Oppenheimer molecular dynamics simulations, employed to take into account all anharmonic and finite temperature effects...

The regulation of lipid synthesis in oil seeds is still not fully understood. Oilseed rape is the third most productive vegetable oil crop on the global market. Therefore, increasing our understanding of lipid accumulation in oilseed rape seeds is of great economic, as well as intellectual, importance. Matrix-assisted laser/desorption ionisation - mass spectrometry imaging (MALDI-MSI) is a technique that allows the mapping of metabolites directly onto intact biological tissues, giving a spatial context to metabolism...

Improvements in genome sequencing technology increased the availability of full genomes and transcriptomes of many organisms. However, the major benefit of massive parallel sequencing is to better understand the organization and function of genes which then lead to understanding of phenotypes. In order to interpret genomic data with automated gene annotation studies, several tools are currently available. Even though the accuracy of computational gene annotation is increasing, a combination of multiple lines of experimental evidences should be gathered...

OBJECTIVE Advanced microsurgical techniques contribute to reduced morbidity and improved surgical management of meningiomas arising within the cerebellopontine angle (CPA). However, the goal of surgery has evolved to preserve the quality of the patient's life, even if it means leaving residual tumor. Concurrently, Gamma Knife radiosurgery (GKRS) has become an acceptable and effective treatment modality for newly diagnosed, recurrent, or progressive meningiomas of the CPA. The authors review their institutional experience with CPA meningiomas treated with GKRS, surgery, or a combination of surgery and GKRS...

Synthetic physiological fluids are currently used as a first in vitro bioactivity assessment for bone grafts. Our understanding about the interactions taking place at the fluid-implant interface has evolved remarkably during the last decade, and does not comply with the traditional International Organization for Standardization/final draft International Standard 23317 protocol in purely inorganic simulated body fluid. The advances in our knowledge point to the need of a true paradigm shift toward testing physiological fluids with enhanced biomimicry and a better understanding of the materials' structure-dissolution behavior...

: 250 Background: Testicular germ cell tumor survivors (TGCTSs) contend with treatment side effects for decades after cure, and many have metabolic syndrome (MTS), a modifiable cardiometabolic risk factor. Because reliably predicting MTS could prompt interventionreducing risk, we analyzed clinical data and body composition in computed tomography (CT) scans to identify associations. METHODS: In a retrospective review of 196 TGCTSs treated at a single institution from 1970 to 2007, we collected patient (pt) demographics, clinical data, body fat composition measures, and evidence from CT scans from baseline through posttreatment...

BACKGROUND: Taxi driving seems to be a strenuous occupation. There was evidence-based paucity of literature on health assessment of taxi drivers. Meanwhile taxi drivers of South Africa were burdened by communicable and non-communicable diseases including high-level exposure to injuries and criminal attacks. Health assessment of this cohort group enables mitigation to engage in appropriation of relevant interventions related to the occupational needs of taxi drivers. OBJECTIVES: The objective of the study was to conduct health assessment of taxi drivers in the city of Tshwane to identify health risk factors...

INTRODUCTION: Through the introduction of advanced analytical techniques and improved throughput, the scope of dried blood spot testing utilising mass spectrometric methods, has broadly expanded. Clinicians and researchers have become very enthusiastic about the potential applications of dried blood spot based mass spectrometric applications. Analysts on the other hand face challenges of sensitivity, reproducibility and overall accuracy of dried blood spot quantification. In this review, we aim to bring together these two facets to discuss the advantages and current challenges of non-newborn screening applications of dried blood spot quantification by mass spectrometry...

: Introduction Comprehensive studies on the relationship between patient demographics and subsequent treatment and disposition at a single mass-gathering event are lacking. The Sydney Royal Easter Show (SRES; Sydney Olympic Park, New South Wales, Australia) is an annual, 14-day, agricultural mass-gathering event occurring around the Easter weekend, attracting more than 800,000 patrons per year. In this study, patient records from the SRES were analyzed to examine relationships between weather, crowd size, day of week, and demographics on treatment and disposition...

BACKGROUND: Obesity and gastroesophageal reflux disease (GERD) are major health problems showing an inconstant relationship in the literature. Therefore, anthropometric parameters which are predictive and can simply be assessed at first patient presentation may lead to a better patient selection for ambulatory reflux monitoring. We aimed to examine the association of body mass index (BMI) and waist to hip ratio (WHR) with gastroesophageal reflux activity during 24 hour-pH-impedance monitoring...

Older observations, which were based solely on light microscopy, suggested that the main stages of oogenesis such as yolk uptake, take place outside the ovary, i.e. in the body or the ovisac cavity in some groups of clitellate annelids. Such extraovarian oogenesis was observed in naidines (Naidinae). Because there are no current data about the ovary organization and the course of oogenesis in Naidinae, we analyzed female gametogenesis in three common representatives of this taxon - Stylaria lacustris, Chaetogaster diaphanus and Ripistes parasita - using light, fluorescent and transmission electron microscopy...

BACKGROUND: More than 90% of the elementary school students in the world and most of the Iranian students use backpacks. Heavy school bags, failure to apply ergonomics standards in student's backpacks, and also mismatch between anthropometrics dimensions and schoolbag size are important issues for children's health. OBJECTIVE: The purpose of this study was to gather baseline information on the average weight carried by female primary students. It also aimed to evaluate ergonomics standards for student backpacks...

Organ transplantation is a lifesaving treatment for patients with end-stage organ failure. Despite the advanced medical science and technology, shortage of organs had led to a growing gap between the demand for organs and the number of donors. With a limited number of studies on the subject and based on those findings, the public knowledge and attitudes must be assessed to understand more clearly that why many people are opposing donating their organs in Saudi Arabia. The objective of our study was to assess the knowledge and attitude of the adult population toward organ donation in Saudi Arabia...
