Tobacco Etch Virus (TEV) protease is used in the purification of recombinant proteins, but its use is often hampered by solubility issues. Here, we report a short, 12-residue solubility enhancing peptide (SEP) tag attached at the C-terminus of TEV (TEV-C9R). We assessed the effects of the C9R tag on the biophysical and biochemical characteristics of TEV. The yield of HPLC purified TEV-C9R expressed in E. coli grown in 200 mL LB or TB media was between 10 and 13 mg, which was up to 6.5 times higher than the yield of the untagged TEV...

More than 50% of Chinese mangroves were lost between 1950 and 2000 to habitat destruction, prompting an urge for conservation. To assess the importance of the protected Maowei Gulf mangrove estuary for fish population assemblage in the Beibu Gulf (China), we studied species composition and abundance of juvenile fish (including larvae) from July 2012 to June 2013. A total of 11 691 specimens were collected, which belonged to 24 species and 15 families. Six perciform species constituted 93% of the total sample...

A passive treatment system (PTS), including two parallel vertical flow bioreactors (VFBR), was constructed in 2008 for the treatment of unabated net-alkaline ferruginous mine drainage in the Tar Creek Superfund Site in northeastern Oklahoma. Water quality data collected since the PTS began operation indicate significant removal of trace metals in the VFBR. Results of a sequential extraction procedure (SEP) performed on substrate samples showed that the majority of Cd, Co, Fe, Ni, Pb, and Zn were retained in the refractory organic/sulfide fraction...

Chronic subdural hematoma (cSDH) is a common condition that disproportionately affects older patients. Given the greater risks of general anesthesia in this population, interest has turned towards less invasive surgical approaches such as the subdural evacuating port system (SEPS; Medtronic, Inc., Minneapolis, MN). There is a relative dearth of information about the outcomes following this procedure. Here, we present our institution's experience with SEPS and analyze factors associated with the outcomes. Using a prospectively maintained institutional database, we retrospectively identified all patients who presented with cSDH and received first line therapy with SEPS...

Building upon evidence linking socio-economic position (SEP) in childhood and adulthood with health-related behaviours (HRB) in adulthood, we examined how pre-adolescent SEP predicted membership of three HRB clusters: "Risky", "Moderate Smokers" and "Mainstream" (the latter pattern consisting of more beneficial HRBs), that were detected in our previous work. Data were taken from two British cohorts (born in 1958 and 1970) in pre-adolescence (age 11 and 10, respectively) and adulthood (age 33 and 34). SEP constructs in pre-adolescence and adulthood were derived through Confirmatory Factor Analysis...

BACKGROUND: Plantar toe ulcers are a challenging surgical problem. There are several methods for reconstruction, but no attention has been given to the preservation of sensation. This report proposes a method to provide protective sensation for the reconstructed area. PATIENTS AND METHODS: The ulcers of seven patients ranged from 2 × 3 to 7 × 3 cm with defects of the plantar first toe and distal metatarsus, including four burns, a trauma, a diabetic ulcer, and a neuropathy injury reconstructed with a distal reverse instep sensory island (DRISI) flap...

BACKGROUND: Winter pea (Pisum sativum L.) grows well in a wide geographic region both as a forage and cover crop. Understanding the quality constituents of this crop is important for both end uses; however, analysis of quality constituents by conventional wet chemistry methods is laborious, slow, and costly. Near Infrared Reflectance Spectroscopy (NIRS) is a precise, accurate, rapid, and cheap alternative to using wet chemistry to estimate quality constituents. We developed and validated NIRS calibration models for constituent analysis of this crop...

BACKGROUND: The risk of falls in people with Multiple Sclerosis (MS) is much greater than that of the general population due to impaired coordination, gait, sensation, muscle tone, strength, and cognition. These MS related falls hamper the day to day living of these individuals and are one of the prime factors aggravating the disease related morbidity. The fear of falling itself may make these individuals more dependent and hinder their professional and leisurely activities. Hence, the significance of identifying individuals who are at risk of falling and instituting preventive counter-measures cannot be overemphasized...

This study aimed to qualify the transfer of Vibrio parahaemolyticus during the shrimp peeling process via gloves under 3 different scenarios. The 1st 2 scenarios provided quantitative information for the probability distribution of bacterial transfer rates from (i) contaminated shrimp (6 log CFU/g) to non-contaminated gloves (Scenario 1) and (ii) contaminated gloves (6 log CFU/per pair) to non-contaminated shrimp (Scenario 2). In Scenario 3, bacterial transfer from contaminated shrimp to non-contaminated shrimp in the shrimp peeling process via gloves was investigated to develop a predictive model for describing the successive bacterial transfer...

OBJECTIVE: Socioeconomic position (SEP) is associated with cerebrovascular health and brain function, particularly in prefrontal cortex (PFC) and medial temporal lobe regions that exhibit plasticity across the lifecourse. However, it is unknown if SEP associates with resting cerebral blood flow (CBF), an indicator of baseline brain function, in these regions in midlife, and if the association is (1) Period-specific, with independent associations for childhood and adulthood SEP, or driven by lifecourse SEP; and (2) Explained by a persistent disparity, widening disparity, or the leveling of disparities with age...

Millions of uninsured Americans do not sign up for available coverage despite job loss or other factors that would make them eligible for special enrollment periods (SEPs). Such periods let people enroll in nongroup insurance outside the usual open enrollment period for Marketplace coverage. Concerned that risk adjustment results in underpayment for the health risks associated with SEP enrollees, carriers rarely market their products to consumers eligible for SEPs, and many do not pay agents and brokers to enroll such consumers...

Synthesis of proteins with noncanonical amino acids (ncAAs) enables the creation of protein-based biomaterials with diverse new chemical properties that may be attractive for material science. Current methods for large-scale production of ncAA-containing proteins, frequently carried out in Escherichia coli, involve the use of orthogonal aminoacyl-tRNA synthetases (o-aaRSs) and tRNAs (o-tRNAs). Although o-tRNAs are designed to be orthogonal to endogenous aaRSs, their orthogonality to the components of the E...

Despite the wide recognition of the inverse association between socioeconomic position (SEP) and suicidal behaviors, its underlying process and potential mediators are little known. This study investigated the pathway from SEP to suicide attempts with attention to potential mediators.From the Korean Health and Nutrition Examination Survey 2007-2013, which is a nationwide cross-sectional survey of the health and nutritional status, a total of 34,565 participants (≥30 years) were included in the analysis. To unfold the pathways linking SEP to suicide attempts, the direct and indirect effects of 3 SEP measures (educational attainment, household income, and occupational group) and 3 mediators (physical illness, mental health problems, and problematic drinking) were differentiated using structured equation model (SEM)...

Research on graphic health warnings (GHWs) indicates that beyond changing cognitions about the health effects of smoking, GHWs evoke emotional reactions that can influence quit-related outcomes. Emotions can be classified based on valence (positive or negative) and arousal (calm or excited). However, although considerable research has examined the differential effectiveness of positive versus negative GHW-evoked emotions, research investigating the role of arousal activation in quit-related behaviors is scarce...
