This study investigated the properties of polyelectrolyte complexes (PECs) fabricated by using ε-polylysine (EPL) and N,O-carboxymethyl chitosan (NOCC) and their potential applications in raw pork. The phase behaviors of PECs in aqueous solutions are characterized by the ζ-potential, mean radius and turbidimetric measurements. Stable colloidal and soluble PEC systems can be fabricated by carefully adjusting the mass ratio of NOCC to EPL. The minimum inhibitory concentration (MIC) assay showed that the colloidal and soluble PECs could maintain the antimicrobial activity of EPL in a laboratory medium...

ETHNOPHARMACOLOGICAL RELEVANCE: Salvia divinorum Epling et Játiva-M (SD, Lamiaceae) is a medicinal plant traditionally used in hallucinogenic ethnopharmacological practices and for its analgesic and antinflammatory properties. Its active compounds include diterpenes known as salvinorins which act as potent κ opioid receptor agonists. AIM OF THE STUDY: Given its effects in acute animal models of pain, as well as its antinflammatory attributes, we decided to investigate the analgesic effects of an SD extract in neuropathic (sciatic loose nerve ligature) and inflammatory (intra plantar carrageenan) pain models in rats...

Importance: Preeclampsia affects approximately 4% of pregnancies in the United States. It is the second leading cause of maternal mortality worldwide and may lead to serious maternal complications, including stroke, eclampsia, and organ failure. Adverse perinatal outcomes for the fetus and newborn include intrauterine growth restriction, low birth weight, and stillbirth. Many of the complications associated with preeclampsia lead to early induction of labor or cesarean delivery and subsequent preterm birth...

Myelofibrosis (MF) is a bone marrow disorder characterized by clonal myeloproliferation, aberrant cytokine production, extramedullary hematopoiesis, and bone marrow fibrosis. Although somatic mutations in JAK2, MPL, and CALR have been identified in the pathogenesis of these diseases, inhibitors of the Jak2 pathway have not demonstrated efficacy in ameliorating MF in patients. TGF-β family members are profibrotic cytokines and we observed significant TGF-β1 isoform overexpression in a large cohort of primary MF patient samples...

For storm drainages inappropriately connected with sewage, wet weather discharge is a major factor that adversely affects receiving waters. A study of the wet weather influences of rainfall-discharge variables on storm drainages connected with sewage was conducted in the downtown Shanghai area (374 ha). Two indicators, event mean concentration (EMC) and event pollutant load per unit area (EPL), were used to describe the pollution discharge during 20 rain events. The study showed that the total rainfall and discharge volume were important factors that affect the EMCs and EPLs of the chemical oxygen demand, total phosphorus, and especially those of NH4(+)-N...

BACKGROUND: Women have strong preferences for their choice of early pregnancy loss (EPL) management. However, current practice patterns suggest that some women may not be offered counseling about the full range of management options. To develop a foundation for quality counseling about EPL treatment, we elicited patients' perspectives regarding their preferences and values for communication during this decision-making process. METHODS: Twenty-one individual interviews were conducted with women who recently experienced EPL...

Importance: Celiac disease is caused by an immune response in persons who are genetically susceptible to dietary gluten, a protein complex found in wheat, rye, and barley. Ingestion of gluten by persons with celiac disease causes immune-mediated inflammatory damage to the small intestine. Objective: To issue a new US Preventive Services Task Force (USPSTF) recommendation on screening for celiac disease. Evidence Review: The USPSTF reviewed the evidence on the accuracy of screening in asymptomatic adults, adolescents, and children; the potential benefits and harms of screening vs not screening and targeted vs universal screening; and the benefits and harms of treatment of screen-detected celiac disease...

Research continues to provide evidence that people are poor multi-taskers. Cognitive resource theory is a common explanation for the inability to efficiently perform multiple tasks at the same time. This theory proposes that one's limited supply of cognitive resources can be utilized faster than it is replenished, which results in a performance decline, particularly when these limited resources must be allocated among multiple tasks. Researchers have proposed both domain-specific, for example, spatial versus verbal processing resources, and domain general cognitive resources...

The U.S. Preventive Services Task Force (USPSTF) summarizes the principles and considerations that guide development of its recommendations for diverse U.S. populations. It uses these principles through each step in the evidence-based guideline process: developing the research plan, conducting the evidence review, developing the recommendation, and communicating to guideline users. Three recent recommendations provide examples of how the USPSTF has used these principles: the 2015 recommendation on screening for abnormal blood glucose and type 2 diabetes; the 2016 recommendation on screening for breast cancer; and the recommendation on screening for prostate cancer, which is currently in progress...

Site-specific functionalization of nanobodies after introducing bioorthogonal groups offers the possibility to biofunctionalize surfaces with a uniformly oriented layer of nanobodies. In this paper, expressed protein ligation (EPL) was used for site-specific alkynation of the model nanobody NbBcII10. In contrast to EPL constructs, which are typically expressed in the cytoplasm, nanobodies are expressed in the periplasm where its oxidizing environment ensures a correct folding and disulfide bond formation. Different pathways were explored to express the EPL constructs in the periplasm but simultaneously, the effect of cytoplasmic expression on the functionality of NbBcII10 was also evaluated...

Otoacoustic emissions (OAEs) provide an acoustic fingerprint of the inner ear, and changes in this fingerprint may indicate changes in cochlear function arising from efferent modulation, aging, noise trauma, and/or exposure to harmful agents. However, the reproducibility and diagnostic power of OAE measurements is compromised by the variable acoustics of the ear canal, in particular, by multiple reflections and the emergence of standing waves at relevant frequencies. Even when stimulus levels are controlled using methods that circumvent standing-wave problems (e...
