Invertase (EC.3.2.1.26) catalyzes the hydrolysis of sucrose to an equimolar mixture of D-glucose and D-fructose which is of interest for various industrial applications. In this research, Saccharomyces cerevisiae invertase gene (SUC2) was optimized based on Pichia pastoris codon preference. The synthetic gene was introduced into the methylotrophic yeast Pichia pastoris under the control of the inducible AOX1 promoter. High level of the extracellular recombinant invertase (R-inv) production was achieved via methanol induction for 4 days and purified by His-Tag affinity chromatography which appeared to be a mixture of glycosylated proteins with various sizes of 85-95 kDa on SDS-PAGE...

Stripe rust caused by Puccinia striiformis f. sp. tritici is most important and devastating disease of wheat worldwide, which affects the grain yields, quality and nutrition. To elucidate, the genetic basis of resistance, a mapping population of recombinant inbred lines was developed from a cross between resistant Cappelle-Desprez and susceptible cultivar PBW343 using single-seed descent. Variety PBW343 had been one of the most popular cultivars of North Western Plains Zone, for more than a decade, before succumbing to the stripe rust...

Even though next-generation sequencing (NGS) has become an invaluable tool in molecular biology, several laboratories with NGS facilities lack trained Bioinformaticians for data analysis. Here, focusing on the variant detection application of NGS analysis, we have developed a fully automated pipeline, namely Variant Discovery and Annotation Tool-Graphical User Interface (VDAP-GUI), which detects and annotates single nucleotide polymorphisms and insertions/deletions from raw sequence reads. VDAP-GUI consolidates several proven methods in each step such as quality control, trimming, mapping, variant detection and annotation...

Keratinocyte carcinoma (KC) is the most common malignancy in the U.S. Because KC affects many people but has a low mortality rate, it is important to consider the impact of KC on skin-related quality of life (QoL). We aimed to determine if KCs, actinic keratoses (AKs), and several demographic and health-related factors were associated with skin- related QoL in those at high risk for KC. We used data from a double-blind, placebo- controlled trial in which 932 veterans with multiple prior KCs were randomized to apply topical 5-fluorouracil (5-FU) or vehicle control cream to the face/ears...

Systemic lupus erythematous is a multi-organ autoimmune disease in which the patient has "lost" self- tolerance and developed immune-complexes containing self-antigen that cause disease through tissue inflammation and multi-organ damage. Patients often have unpredictable flares in symptoms with poorly identified triggers. However, it has been suggested in other literature that exogenous exposures, including ingested beef, cigarette smoke, UV radiation, metal-complexing agents, and infections can contribute to exacerbations and improvements in SLE symptoms...

Advanced percutaneous and surgical procedures in structural and congenital heart disease require precise pre-procedural planning and continuous quality control. Although current imaging modalities and post-processing software assists with peri-procedural guidance, their capabilities for spatial conceptualization remain limited in two- and three-dimensional representations. In contrast, 3D printing offers not only improved visualization for procedural planning, but provides substantial information on the accuracy of surgical reconstruction and device implantations...

Study Objectives: Obstructive sleep apnea (OSA) is a common sleep disorder. Actually, literature lacks studies examining sleep, cognition, and Alzheimer's Disease (AD) cerebrospinal-fluid biomarkers in OSA patients. Therefore, we firstly studied cognitive performances, polysomnographic sleep, and CSF β-amyloid, tau proteins and lactate levels in patients affected by subjective cognitive impairment (SCI) divided in three groups: OSA patients (showing an Apnea-Hypopnea Index - AHI ≥15/h), controls (showing an AHI<15/h), and patients treating OSA by continuous positive airway pressure (CPAP)...

Exercise improves cognitive function in older adults, but the underlying mechanism is largely unknown. Both lysosomal degradation and mitochondrial quality control decline with age. We hypothesized that exercise ameliorates age-related cognitive decline through the improvement of mitochondrial quality control in aged hippocampus, and this effect is associated with lysosomal proteolysis. Sixteen to eighteen-month old male Sprague Dawley rats underwent swim exercise training for 10 weeks. The exercise regimen prevented cognitive decline in aged rats, reduced oxidative stress, and rejuvenated mitochondria in the aged hippocampus...

Background: Rapid diagnostic tests (RDTs) are an important tool for malaria diagnosis, with most utilising antibodies against histidine-rich protein 2 (PfHRP2). Reports of Plasmodium falciparum lacking this protein are increasing, creating a problem for diagnosis of falciparum malaria in locations without quality microscopy. Methods: An agent-based stochastic simulation model of P.falciparum transmission was used to investigate the selective pressure exerted on parasite populations by use of RDTs for diagnosis of symptomatic cases...

OBJECTIVES: There is growing evidence for increased levels of pain and reduced health-related quality of life in survivors of critical illness. Recent studies showed marked small nerve fiber pathology in critically ill patients, which may contribute to chronic pain states and reduced physical recovery after ICU discharge. Primary objective of this study was the comparison of somatosensory functions between survivors of critical illness 6 months after ICU discharge and controls. In post hoc analyses, we aimed to identify associations between small fiber deficits, pain, health-related quality of life, and clinical data...

BACKGROUND: Recently, the total prostate-specific antigen (PSA) assay used in a laboratory had a positive bias of 0.03 μg/L, which went undetected. Consequently, a number of post-prostatectomy patients with previously undetectable PSA concentrations (defined as <0.03 μg/L in that laboratory) were being reported as having detectable PSA, which suggested poorer prognosis according to clinical guidelines. METHODS: Through numerical simulations, we explored (1) how a small bias may evade the detection of routine quality control (QC) procedures with specific reference to the concentration of the QC material, (2) whether the use of 'average of normals' approach may detect such a small bias, and (3) describe the use of moving sum of number of patient results with detectable PSA as an adjunct QC procedure...
