Sternal-wound infections (SWIs) are rare but consequential healthcare-healthcare-associated infections following coronary artery bypass graft surgery (CABG). The impact of SWIs associated on the cost of health care provision is unknown. The aim of this study was to quantify the burden of CABG-related SWIs across countries with mature health care systems and estimate value-based purchasing (VBP) levels based on the local burden.

A structured literature review identified relevant data for 14 countries (the Netherlands, France, Germany, Austria, the United Kingdom, Canada, Italy, Japan, Spain, the United States, Brazil, Israel, Taiwan, and Thailand). Data, including SWI rates, CABG volume, and length of stay, were used to populate a previously published Markov model that simulates the patient's CABG-care pathway and estimates the economic (US$) and care burden of SWIs for each country. Based on this burden, scenarios for VBP were explored for each country. A feasible cost of intervention per patient for an i a large burden with a median cost of US$13 995 per case and US$900 per CABG procedure. By tackling SWIs, there is potential to simultaneously reduce the burden on health care systems and improve outcomes for patients. Mutually beneficial VBP agreements might be one method to promote uptake of novel methods of SWI prevention.

To describe the diagnostic performance of a deep learning algorithm in discriminating early-stage Fuchs' endothelial corneal dystrophy (FECD) without clinically evident corneal edema from healthy and late-stage FECD eyes using high-definition optical coherence tomography (HD-OCT).

In this observational case-control study, 104 eyes (53 FECD eyes and 51 healthy controls) received HD-OCT imaging (Envisu R2210, Bioptigen, Buffalo Grove, IL, USA) using a 6 mm radial scan pattern centered on the corneal vertex. FECD was clinically categorized into early (without corneal edema) and late-stage (with corneal edema). A total of 18,720 anterior segment optical coherence tomography (AS-OCT) images (9180 healthy; 5400 early-stage FECD; 4140 late-stage FECD) of 104 eyes (81 patients) were used to develop and validate a deep learning classification network to differentiate early-stage FECD eyes from healthy eyes and those with clinical edema. Using 5-fold cross-validation on the dataset containing 11,340 OCT images (63 tool of FECD with very high sensitivity and specificity that can be used to grade FECD severity with high accuracy.

Deep learning algorithm is an accurate autonomous novel diagnostic tool of FECD with very high sensitivity and specificity that can be used to grade FECD severity with high accuracy.

Football has the highest number of nontraumatic fatalities of any sport in the United States.

To compare the incidence of nontraumatic fatalities with that of traumatic fatalities, describe the epidemiology of nontraumatic fatalities in high school (HS) and college football players, and determine the effectiveness of National Collegiate Athletic Association (NCAA) policies to reduce exertional heat stroke (EHS) and exertional sickling (ES) with sickle cell trait (SCT) fatalities in athletes.

Descriptive epidemiology study.

We retrospectively reviewed 20 academic years (1998-2018) of HS and college nontraumatic fatalities in football players using the National Registry of Catastrophic Sports Injuries (NRCSI). EHS and ES with SCT fatality rates were compared before and after the implementation of the NCAA football out-of-season model (bylaw 17.10.2.4 [2003]) and NCAA Division I SCT screening (bylaw 17.1.5.1 [2010]), respectively. Additionally, we compiled incidence trends for HS and college traumatic anuction in the risk of traumatic fatalities. Current HS and college nontraumatic fatality rates are significantly higher than rates of traumatic fatalities. The 2003 NCAA out-of-season model has failed to significantly reduce EHS fatalities. The 2010 NCAA SCT screening bylaw has effectively prevented ES with SCT fatalities in NCAA Division I football.

TGF-β isoforms play crucial roles in diverse cellular processes. Therefore, targeting and inhibiting TGF-β signaling pathway provides a potential therapeutic opportunity. TGF-β isoforms bind and bring the receptors (TβRII and TβRI) together to form a signaling complex in an ordered manner.

Herein, an antagonistic variant of TGF-β (AnTβ) has been designed and prepared to inhibit the formation of signaling complex and consequently its signaling pathway. This TGF-β homodimeric variant contains intact TβRII binding sites and blocked TβRI binding sites by substituting three peptide segments. So, AnTβ could only bind to TβRII, but prevent binding and recruitment of TβRI to form a signaling complex.

A reliable model of AnTβ was built and refined using molecular dynamics (MD) simulation, followed by investigating the interactions of AnTβ with the receptors using in silico docking studies. After expression of disulfide-linked AnTβ in a SHuffle strain and purification of the protein using affinity chromatography, its biological activity was evaluated using Mink lung epithelial cells (Mvl Lu).

No meaningful significant changes in AnTβ structure were observed when compared with the native protein. Based on the docking analysis, AnTβ binds to TβRII similar to TGF-β and its binding to TβRI was diminished considerably which was consistent with our design purpose. Cell-based bioassay indicated that AnTβ could modulate TGF-β-induced cell growth inhibition.

Our analysis suggests that the antagonistic potency of AnTβ can be used as an anti-TGFβ signaling factor in the future perspectives.

Many problems of combinatorial optimization, which are solvable only in exponential time, are known to be Non-Deterministic Polynomial hard (NP-hard). With the advent of parallel machines, new opportunities have been emerged to develop the effective solutions for NP-hard problems. However, solving these problems in polynomial time needs massive parallel machines and is not applicable up to now.

DNA (Deoxyribonucleic acid) computing provides a fantastic method to solve NP-hard problems in polynomial time. Accordingly, one of the famous NP-hard problems is assignment problem, which is designed to find the best assignment of n jobs to n persons in a way that it could maximize the profit or minimize the cost.

Applying bio molecular operations of Adelman Lipton model, a novel parallel DNA algorithm have been proposed for solving the assignment problem.

The proposed algorithm can solve the problem in time complexity, and just O(n

) initial DNA strand in comparison with nn initial sequence, which is used by the other methods.

In this article, using DNA computing, we proposed a parallel DNA algorithm to solve the assignment problem in linear time.

Cysteine proteases of the liver fluke, Fasciola hepatica, participate in catabolism of proteins, migration of the fluke through host tissues and combat host immune system.

In this study, we evaluated proteolytic activity of F. hepatica recombinant cathepsin L1 (rCL1) against gelatin and collagen as common substrates.

The coding sequences of F. hepatica CL1 were cloned and expressed in E. coli, in our previous study. The rCL1 was purified by nickel affinity chromatography with a HisTrap Column. The protein concentrations of the purified fractions were determined by Bradford assay. Rat collagen type-1 was treated with distinct amounts of rCL1 at 37 °C, overnight, and the byproduct was analyzed by SDS-PAGE. Furthermore, we used bovine skin gelatin as zymography substrate to evaluate the gelatinolytic activity of the purified rCL1.

Recombinant CL1 was capable to digest intact type-1 collagen within 24 h and the gelatinlytic activity of rCL1 was visible at approximately 37 kDa region, with optimal activity at acidified conditions (pH 4).

Findings provide a possible mechanism by which a major secretory molecule of F. hepatica could be involved in parasite survival as well as its pathogenesis.

Phenol is an aromatic pollutant in industrial wastes that in combination with salts is highly toxic for all forms of life. Phenol elimination is the foremost challenge to meet the goal of pollutant-free environment.

The present study was carried out to isolate phenol degrading bacteria which can degrade phenol under saline conditions and to identify the isolated strains using 16S rRNA gene sequence analysis.

Sediment samples were collected from Rawal Lake, Islamabad, Pakistan and enriched in mineral salt medium (MSM) containing phenol (150 mg.L

). Isolated strains were identified on the basis of 16S rRNA gene sequence analysis. Growth of strains were tested at different pH, NaCl concentrations and temperature using Tryptic Soy Agar (TSA). Tolerance to phenol (0-750 mg.L

) was checked at 5% NaCl and phenol degrading experiment was performed at 4% NaCl, pH 7 and 30 oC. In both, phenol tolerance and degradation study, phenol was used a sole source of carbon and energy.

Thirteen bacterial strains were isolated after enrichment among which, NIGAB-1 was found capable of degrading phenol in saline conditions. This strain was identified as

sp. NIGAB-1 on the basis of 16S rRNA gene sequence analysis and the closest match was

with 99.71% sequence identity. The

sp. NIGAB-1 exhibited best growth at 30 oC at pH 7 with 10% NaCl. The optimum phenol concentration for growth was recorded as 300 mg.L

. This strain degraded 300 mg.L-1 of phenol at 4% NaCl in 120 hours with the average degradation rate of 2.63 mg.L

.h.

These findings suggest that this strain could be efficient in phenol degradation at adverse environmental conditions and helpful in remediation of phenol where the salt concentration is high.

Clear cell renal cell carcinoma (ccRCC) represents approximately 70% of RCC,as the most frequent histological subtype of RCC. MiR-138-5p, a tumor-related microRNA (miRNA), has been reported to be implicated in the diverse types of human malignancies, but its role in ccRCCremains unclear.

The study was designed to investigate the functional behaviors and regulatory mechanisms of miR-138-5p in ccRCC.

Quantitative real-time PCR and western blotting analyses were performed to determine the expression of miR-138-5p and TMEM40 in ccRCC tissues. Pearson's correlation coefficient was utilized to evaluate the correlation between miR-138-5p and TMEM40 expression. The function of miR-138-5p and TMEM40 in the cell proliferation, migration and invasion of ccRCC cells (786-O and ACHN) was assessed by CCK-8, colony formation, wound healing and transwell assay, respectively. A luciferase reporter assay was performed to confirm the direct binding of miR-138-5p to the target gene TMEM40.

We found the expression of miR-138-5p was significantly down-regulated, while TMEM40 was remarkably up-regulated in ccRCC tissues.
