Equine herpesvirus type 1 (EHV-1) UL11 is a 74-amino-acid tegument protein encoded by ORF51 of the EHV-1 genome. EHV-1 UL11 was previously reported by other researchers using the RacL22 and RacH strains to be nonessential for viral replication in cultured cells. Here, we constructed UL11 mutant viruses including a UL11 null mutant and three C-terminal truncated mutants, for further characterization of EHV-1 UL11 using bacterial artificial chromosome (BAC) technology based on the neuropathogenic strain Ab4p...

BACKGROUND: Accurate assessment of kidney function is clinically important, but estimates of glomerular filtration rate (GFR) by regression are imprecise. METHODS: We hypothesized that ensemble learning could improve precision. A total of 1419 participants were enrolled, with 1002 in the development dataset and 417 in the external validation dataset. GFR was independently estimated from age, sex and serum creatinine using an artificial neural network (ANN), support vector machine (SVM), regression, and ensemble learning...

The multifunctional Eya1 protein plays important roles during the development of cranial sensory organs and ganglia, kidneys, hypaxial muscles and several other organs in vertebrates. Eya1 is encoded by a complex locus with candidate cis-regulatory elements distributed over a 329 kbp wide genomic region in Xenopus. Consequently, very little is currently known about how expression of Eya1 is controlled by upstream regulators. Here we use a library of Xenopus tropicalis genomic sequences in bacterial artificial chromosomes (BAC) to analyze the genomic region surrounding the Eya1 locus for enhancer activity...

BACKGROUND: The use of artificial colloids has declined in critical care, whereas they are still used in perioperative medicine. Little is known about the nephrotoxic potential in noncritically ill patients during routine surgery. The objective of this trial was to evaluate the influences of albumin 5% and balanced hydroxyethyl starch 6% (130/0.4) on renal function and kidney injury. METHODS: One-hundred urologic patients undergoing elective cystectomy were randomly assigned for this prospective, single-blinded, controlled study with two parallel groups to receive either albumin 5% or balanced hydroxyethyl starch 6% (130/0...

Aspartame is one of the most popular artificial sweeteners over the world. Although its consumption is considered to be safe in acceptable daily intake ranges which were set by the United States Food and Drugs Administration and other regulatory agencies, there are lots of controversies regarding its safety nowadays. Some of the recent experimental and epidemiological studies showed that consumption of aspartame may causes some adverse health effects including obesity, metabolic syndrome, and alteration in gut microbiota...

In this study, all genetic female(XX)broods of Japanese flounder were produced artificially by mating the females with sex-reversed males. The proliferation and migration of primordial germ cells (PGCs), formation of ovary and oogenesis were described in detail. After hatching, around 20 individual PGCs migrated from the lateral to the dorsal of trunk region. At 15 days post hatching (dph), a part of PGCs were covered by a single layer somatic cells and formed the genital ridge. By 22 dph, the elongated gonadal primordia appeared under the ventral kidney, where the PGCs were totally enclosed by somatic cells...

The use of uranium and to a minor extent plutonium as fuel for nuclear energy production or as components in military applications is under increasing public pressure. Uranium is weakly radioactive in its natural isotopy but its chemical toxicity, combined with its large scale industrial utilization, makes it a source of concern in terms of health impact for workers and possibly the general population. Plutonium is an artificial element that exhibits both chemical and radiological toxicities. So far, uranium (under its form uranyl, U(vi)) or plutonium (as Pu(iv)) decorporation or protecting strategies based on molecular design have been of limited efficiency to remove the actinide once incorporated after human exposure...

Kidney transplantation is the treatment of choice for patients with end-stage renal disease (ESRD). Prediction of the transplant survival is of paramount importance. The objective of this study was to develop a model for predicting survival in kidney transplant recipients. In a cross-sectional study, 717 patients with ESRD admitted to Nemazee Hospital during 2008-2012 for renal transplantation were studied and the transplant survival was predicted for 5 years. The multilayer perceptron of artificial neural networks (MLP-ANN), logistic regression (LR), Support Vector Machine (SVM), and evaluation tools were used to verify the determinant models of the predictions and determine the independent predictors...

The optimal nutritional support in Acute Kidney Injury (AKI) still remains an open issue. The present study was aimed at evaluating the validity of conventional predictive formulas for the calculation of both energy expenditure and protein needs in critically ill patients with AKI. A prospective, multicenter, observational study was conducted on adult patients hospitalized with AKI in three different intensive care units (ICU). Nutrient needs were estimated by different methods: the Guidelines of the European Society of Parenteral and Enteral Nutrition (ESPEN) for both calories and proteins, the Harris-Benedict equation, the Penn-State and Faisy-Fagon equations for energy...

The invention of dialysis has been a phenomenal advance in the treatment of kidney failure. The introduction of artificial kidneys in clinical care remains one of the most successful lifesaving interventions in modern medicine. Its glory, however, has been tempered by poor long-term outcomes and a negative qualitative impact on the lives of patients who suffer from an extremely complex, burdensome, and restricted life on dialysis. There remains a huge gap in patient well-being and outcomes between artificial kidney treatments and kidney transplantation...

Vitamin D, the sunshine vitamin is important for health. Those with fat malabsorption disorders malabsorb vitamin D and thus must rely on cutaneous production of vitamin D3. Vitamin D3 is generated secondary to exposure to ultraviolet B (UVB) radiation (whether from the sun or from an artificial source). Light emitting diodes (LEDs) have been developed to emit ultraviolet radiation. Little is known about the efficiency of UVB emitting LEDs tuned to different wavelengths for producing vitamin D3 in human skin...

BACKGROUND: Food products containing non-nutritive sweeteners (NNSs) instead of sugar have become increasingly popular in the last decades. Their appeal is obviously related to their calorie-free sweet taste. However, with the dramatic increase in their consumption, it is reasonable and timely to evaluate their potential health benefits and, more importantly, potential adverse effects. The main aim of this scoping review was to map the evidence about health outcomes possibly associated with regular NNS consumption by examining the extent, range, and nature of research activity in this area...

The proper formation of synapses-specialized unitary structures formed between two neurons-is critical to mediating information flow in the brain. Synaptic cell adhesion molecules (CAMs) are thought to participate in the initiation of the synapse formation process. However, in vivo functional analysis demonstrates that most well known synaptic CAMs regulate synaptic maturation and plasticity rather than synapse formation, suggesting that either CAMs work synergistically in the process of forming synapses or more CAMs remain to be found...

Dipstick urinalysis is an informative, quick, cost-effective and non-invasive diagnostic tool that is useful in clinical practice for the diagnosis of urinary tract infections (UTIs), kidney diseases, and diabetes. We used dipstick urinalysis as a hands-on microbiology laboratory exercise to reinforce student learning about UTIs with a particular focus on cystitis, which is a common bacterial infection. To avoid exposure to potentially contaminated human urine samples, we prepared artificial urine using easily acquired and affordable ingredients, which allowed less-experienced students to perform urinalysis without the risk of exposure to pathogenic organisms and ensured reliable availability of the urine samples...

Tooth formation during embryogenesis is controlled through a complex interplay between mechanical and chemical cues. We have previously shown that physical cell compaction of dental mesenchyme cells during mesenchymal condensation is responsible for triggering odontogenic differentiation during embryogenesis, and that expression of Collagen VI stabilizes this induction. In addition, we have shown that synthetic polymer scaffolds that artificially induce cell compaction can induce embryonic mandible mesenchymal cells to initiate tooth differentiation both in vitro and in vivo...

We report the development and validation of two quantitative PCR (qPCR) assays to detect Nanophyetus salmincola DNA in water samples and in fish and snail tissues. Analytical and diagnostic validation demonstrated good sensitivity, specificity, and repeatability of both qPCR assays. The N. salmincola DNA copy number in kidney tissue was significantly correlated with metacercaria counts based on microscopy. Extraction methods were optimized for the sensitive qPCR detection of N. salmincola DNA in settled water samples...
