The first article of a two-article series presents pervaporation (PV) of volatile aroma compounds from fruit juice hydrolates (plum, apple, blackcurrant and cherry). The purpose of this research was to evaluate the effectiveness of fruit juice hydrolates separation on a laboratory scale (inert gas flow pervaporation system) and semi-technical (vacuum pervaporation system) by means of pervaporation. To create precise matrices for hydrolates before and after pervaporation for each of the separated systems, solid phase microextraction (SPME) technique and the gas chromatography-mass spectrometry (GC-MS) was applied...

For decades, fungi have been a source of U.S. Food and Drug Administration-approved natural products such as penicillin, cyclosporine, and the statins. Recent breakthroughs in DNA sequencing suggest that millions of fungal species exist on Earth, with each genome encoding pathways capable of generating as many as dozens of natural products. However, the majority of encoded molecules are difficult or impossible to access because the organisms are uncultivable or the genes are transcriptionally silent. To overcome this bottleneck in natural product discovery, we developed the HEx (Heterologous EXpression) synthetic biology platform for rapid, scalable expression of fungal biosynthetic genes and their encoded metabolites in Saccharomyces cerevisiae ...

Yue Wang, Cherry Gregory, Mark A Minor
Molded silicone rubbers are common in manufacturing of soft robotic parts, but they are often prone to tears, punctures, and tensile failures when strained. In this article, we present a fabric compositing method for improving the mechanical properties of soft robotic parts by creating a fabric/rubber composite that increases the strength and durability of the molded rubber. Comprehensive ASTM material tests evaluating the strength, tear resistance, and puncture resistance are conducted on multiple composites embedded with different fabrics, including polyester, nylon, silk, cotton, rayon, and several blended fabrics...

Pathogenic Acanthamoeba species often cause infection known as Acanthamoeba keratitis among people who use contact lenses. It is a type of infection that can result in corneal ulceration, visual loss or even blindness, if not treated. There are various therapeutic options available in the treatment of Acanthamoeba infections but they are usually tough treatments with limited efficacy. For instance, hydrogen peroxide (H2 O2 ) is a commonly used contact lens disinfectant which is effective against Acanthamoeba but it is toxic to the cornea...

Brent A Hackett, Sara Cherry
Flaviviruses enter host cells through the process of clathrin-mediated endocytosis, and the spectrum of host factors required for this process are incompletely understood. Here we found that lymphocyte antigen 6 locus E (LY6E) promotes the internalization of multiple flaviviruses, including West Nile virus, Zika virus, and dengue virus. Perhaps surprisingly, LY6E is dispensable for the internalization of the endogenous cargo transferrin, which is also dependent on clathrin-mediated endocytosis for uptake. Since viruses are substantially larger than transferrin, we reasoned that LY6E may be required for uptake of larger cargoes and tested this using transferrin-coated beads of similar size as flaviviruses...

OBJECTIVE: Dementia represents a major risk factor for medical complications and has been linked to higher rates of complication after surgery. Given the systemic nature of vascular disease, medical comorbidities significantly increase cost and complications after vascular surgery. We hypothesize that the presence of dementia is an independent predictor of increased postoperative complications and higher health care costs after vascular surgery. METHODS: The Vascular Quality Initiative database was queried for all patients undergoing vascular surgery at a single academic medical center from 2012 to 2017...

The influence of process parameters on the extraction of anthocyanins from the edible portion of fresh, sweet cherry were investigated. The optimal extraction time and temperature were determined as 90 min and 37 °C, respectively. A solvent/solid ratio of 10 mL/g using 100% acidified solvent resulted in the greatest anthocyanin yield. No significant difference was observed between the use of methanol or ethanol as the extraction solvent. Ultra Performance Liquid Chromatography-MS analysis of the extract identified four anthocyanins, with cyanidin-3-rutinoside and peonidin-3-rutinoside accounting for over 95% of the anthocyanin content, while cyanidin-3-glucoside and pelargonidin-3-rutinoside accounted for the remaining 5%...

BACKGROUND AND AIM: Acute upper gastrointestinal bleeding (UGIB) in cirrhosis is associated with significant morbidity and mortality and can be classified as acute variceal bleeding (AVB) or non-variceal bleeding (NVB). Differences in mortality, hospital length of stay (LOS) and 30-day readmission have yet to be determined. As such, we aimed to evaluate differences in these clinical outcomes in cirrhotic patients admitted with UGIB. METHODS: This retrospective study included all cirrhotic patients hospitalized for UGIB who underwent upper endoscopy from July 2014 to July 2016...
