Groundwater qanat potential mapping using frequency ratio and Shannon’s entropy models in the Moghan watershed, Iran

The purpose of current study is to produce groundwater qanat potential map using frequency ratio (FR) and Shannon's entropy (SE) models in the Moghan watershed, Khorasan Razavi Province, Iran. The qanat is basically a horizontal, interconnected series of underground tunnels that accumulate and deliver groundwater from a mountainous source district, along a water- bearing formation (aquifer), and t

No increased risk of short-term complications after radical cystectomy for muscle-invasive bladder cancer among patients treated with preoperative chemotherapy : a nation-wide register-based study

Purpose: Preoperative chemotherapy is underused in conjunction with radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) due to concerns for complications and delay of surgery. Prospective data on short-term complications from population-based settings with frequent use of preoperative chemotherapy and standardised reporting of complications is lacking. Methods: We identified 1,340 pa

Calcein release assay as a method for monitoring serum complement activity during monoclonal antibody therapy in patients with B-cell malignancies

Monoclonal antibodies ofatumumab (anti-CD20) and alemtuzumab (anti-CD52) which are approved for usage in patients with chronic lymphocytic leukemia (CLL), efficiently activate the classical complement pathway. However complement is an exhaustible component and high doses of its activators may deplete complement-dependent cytotoxicity (CDC) potential, thus reducing the effect of repeated mAb dosing

Inflammatory bowel disease promotes venous thrombosis earlier in life

Background: Patients with inflammatory bowel disease (IBD) may be at increased risk of having venous thromboembolism. Methods: Medical records from 1253 IBD patients attending hospital care during the years 1987-97 were studied. These patients were recruited from a population of 340,000 inhabitants. Patients with verified venous thrombosis were characterized clinically, and blood samples were exam

Mortality patterns in long-term survivors of childhood or adolescent central nervous system tumour in Sweden

PURPOSE: A growing number of young patients with central nervous system (CNS) tumour survived for more than five years. However, these long-term survivors might be at risk of multiple late effects thus leading to a higher risk of late mortality. We aimed to explore the risk of late mortality and the pattern of mortality among long-term survivors of childhood or adolescent CNS tumour.METHODS: We id

Influence of Injection Strategies on Engine Efficiency for a Methanol PPC Engine

Partially premixed combustion (PPC) is one of several advanced combustion concepts for the conventional diesel engine. PPC uses a separation between end of fuel injection and start of combustion, also called ignition dwell, to increase the mixing of fuel and oxidizer. This has been shown to be beneficial for simultaneously reducing harmful emissions and fuel consumption. The ignition dwell can be

Large Eddy Simulation of an Ignition Front in a Heavy Duty Partially Premixed Combustion Engine

In partially premixed combustion engines high octane number fuels are injected into the cylinder during the late part of the compression cycle, giving the fuel and oxidizer enough time to mix into a desirable stratified mixture. If ignited by auto-ignition such a gas composition can react in a combustion mode dominated by ignition wave propagation. 3D-CFD modeling of such a combustion mode is chal

Exploring the visual world of fossilized and modern fungus gnat eyes (Diptera : Keroplatidae) with X-ray microtomography

Animal eyes typically possess specialized regions for guiding different behavioural tasks within their specific visual habitat. These specializations, and evolutionary changes to them, can be crucial for understanding an animal's ecology. Here, we explore how the visual systems of some of the smallest flying insects, fungus gnats, have adapted to different types of forest habitat over time (approx

The effect of temperature and moisture on lag phase length of bacterial growth in soil after substrate addition

Microorganisms in soil are commonly limited by available substrate, and removing the limitation will increase activity and growth, with predictable dynamics in growth. The initial phase with a lag period (λ) will usually be followed by exponential growth (also called log phase, with growth rate μ). These two growth phases may be differently affected by environmental conditions, like temperature an

Polypoidal Choroidal Vasculopathy Associate With Diminished Regulatory T Cells That Are Polarized Into a T Helper 2-Like Phenotype

Purpose: To investigate possible roles of T helper (Th) cells, regulatory T cells (Tregs), and the recently mapped Th-like Tregs in patients with polypoidal choroidal vasculopathy (PCV). Methods: In this prospective case-control study, we obtained fresh venous blood from patients with PCV (n = 24), age-matched healthy controls (n = 32), and patients with neovascular AMD (n = 45). All participants

Somatic late effects in 5-year survivors of neuroblastoma : a population-based cohort study within the Adult Life after Childhood Cancer in Scandinavia study

Because of the rarity of neuroblastoma and poor survival until the 1990s, information on late effects in neuroblastoma survivors is sparse. We comprehensively reviewed the long-term risk for somatic disease in neuroblastoma survivors. We identified 721 5-year survivors of neuroblastoma in Nordic population-based cancer registries and identified late effects in national hospital registries covering

Biomarkers of Exposure to Pyrimethanil After Controlled Human Experiments

Pyrimethanil (PYM) is a fungicide used pre- and post-harvest on many crops. It has a low acute toxicity but is of toxicological concern because of its antiandrogenic properties. The aim of the current work was to investigate some metabolism and estimate elimination kinetics of PYM in humans after experimental oral and dermal exposure. A liquid chromatography triple quadrupole mass spectrometry (LC

A New SITA Perimetric Threshold Testing Algorithm : Construction and a Multicenter Clinical Study

Purpose: To describe a new time-saving threshold visual field–testing strategy—Swedish Interactive Thresholding Algorithm (SITA) Faster, which is intended to replace SITA Fast—and to report on a clinical evaluation of this new strategy. Design: Description and validity analysis for modifications applied to SITA Fast. Methods: Five centers tested 1 eye of each of 126 glaucoma and glaucoma suspect p

Acute Stroke Care in Dementia : A Cohort Study from the Swedish Dementia and Stroke Registries

METHODS: Retrospective analysis of prospectively collected data 2010-2014 from the Swedish national dementia registry (SveDem) and the Swedish national stroke registry (Riksstroke). Patients with dementia who suffered an acute ischemic stroke (AIS) (n = 1,356) were compared with matched non-dementia AIS patients (n = 6,755). Outcomes included length of stay in a stroke unit, total length of hospit

The impact of parenthood on risk of registration for alcohol use disorder in married individuals : A Swedish population-based analysis

BackgroundAlthough being married with children is associated with a reduced rate of alcohol use disorder (AUD), is this finding independent of a marital effect, different in mothers and fathers and potentially causal in effect.MethodsUsing Cox proportional hazards, we examined, in 1 252 237 married individuals, the association between a resident younger and older child and risk for AUD registratio

NANC neurotransmission in lamina propria of the rabbit urethra : regulation by different subsets of calcium channels

Electrical field stimulation (EFS) of the rabbit urethral lamina propria elicited a frequency‐dependent non‐adrenergic, non‐cholinergic (NANC) relaxation, which was abolished by NΩ–nitro‐L‐arginine (l‐NOARG). Ω‐Conotoxin GVIA, a selective blocker of N‐type voltage‐operated calcium channels (VOCCs), and Ω‐conotoxin MVIIC (blocker of N‐ and Q‐type VOCCs) inhibited the NANC relaxation, and the inhibi
