Structures of power and inequality shape day-to-day life for individuals who are poor, imposing waiting in multiple forms and for a variety of services, including for healthcare (Andaya, 2018a; Auyero, 2012; Strathmann and Hay, 2009). Constraints, such as the age requirements for Medicare, losing employer-provided health insurance, or the bureaucracy involved in filing for disability often require people to wait to follow recommendations for medical treatments. In 2016-2017, we conducted 52 narrative interviews in St. Louis, a city with significant racial and economic health inequities and without Medicaid expansion. We interviewed people with one or more chronic illnesses for which they were prescribed medication and who identified as having difficulties affording their prescriptions. Throughout the interviews, participants frequently recounted 1) experiences of waiting for care, along with other services, and 2) the range of strategies they utilized to manage the waiting. In this article, we develop the concept of active waiting to describe both the lived experiences of waiting for care and the responses that people devise to navigate, shorten, or otherwise endure waiting. Waiting is structured into healthcare and other social services at various scales in ways that reinforce feelings of marginalization, and also that require work on the part of those who wait. While much medical and public health research focuses on issues of diagnostic or treatment delay, we conclude that this conceptualization of active waiting provides a far more productive frame for accurately understanding the emotional and physical experiences of individuals who are disproportionately poor and made to wait for their care. Only with such understanding can we hope to build more just and compassionate social systems.Despite mounting evidence for the role of inflammation in Major Depressive Disorder (MDD), in vivo preclinical investigations of inflammation-induced negative affect using whole brain imaging modalities are scarce, precluding a valid model within which to evaluate pharmacological interventions. Here we used an E. coli lipopolysaccharide (LPS)-based model of inflammation-induced depressive signs in rats to explore brain changes using multimodal neuroimaging methods. During the acute phase of the LPS response (2 h post injection), prior to the emergence of a task-quantifiable depressive phenotype, striatal glutamine levels and splenial, retrosplenial, and peri-callosal hippocampal cortex volumes were greater than at baseline. LPS-induced depressive behaviors observed at 24 h, however, occurred concurrently with lower than control levels of striatal glutamine and a reversibility of volume expansion (i.e., shrinkage of splenial, retrosplenial, and peri-callosal hippocampal cortex to baseline volumes). In both striatum and hippocampus at 24 h, mRNA expression in LPS relative to control animals demonstrated alterations in enzymes and transporters regulating glutamine homeostasis. Collectively, the observed behavioral, in vivo structural and metabolic, and mRNA expression alterations suggest a critical role for astrocytic regulation of inflammation-induced depressive behaviors.Current techniques for Gram-typing and for diagnosing a pathogen at the early infection stage rely on Gram stains, cultures, Enzyme linked immunosorbent assay (ELISA), polymerase chain reaction (PCR), and gene microarrays, which are labor-intensive and time-consuming approaches. In addition, a delayed or imprecise diagnosis of clinical pathogenic bacteria leads to a life-threatening emergency or overuse of antibiotics and a high-rate occurrence of antimicrobial-resistance microbes. Herein, we report high-performance antibiotics (as bioprobes) conjugated graphene micropattern field-effect transistors (ABX-GMFETs) to facilitate on-site Gram-typing and help in the detection of the presence or absence of Gram-negative and -positive bacteria in the samples. The ABX-GMFET platform, which consists of recognition probes and GM transistors conjugated with novel interfacing chemical compounds, was integrated into the microfluidics to minimize the required human intervention and facilitate automation. The mechanism of binding of ABX-GMFET was based on a charge or chemical moiety interaction between the bioprobes and target bacteria. Subsequently, ABX-GMFETs exhibited unprecedented high sensitivity with a limit of detection (LOD) of 100 CFU/mL (1-9 CFU/mL), real-time target specificity.
The aim of the study was to determine whether corticospinal excitability and inhibition of the tibialis anterior during single-leg standing differs among individuals with chronic ankle instability (CAI), lateral ankle sprain copers, and healthy controls.

Twenty-three participants with CAI, 23 lateral ankle sprain copers, and 24 healthy control participants volunteered. Active motor threshold (AMT), normalized motor-evoked potential (MEP), and cortical silent period (CSP) were evaluated by transcranial magnetic stimulation while participants performed a single-leg standing task.

Participants with CAI had significantly longer CSP at 100% of AMT and lower normalized MEP at 120% of AMT compared to lateral ankle sprain copers (CSP
p = 0.003; MEP
p = 0.044) and controls (CSP
p = 0.041; MEP
p = 0.006).

This investigation demonstrated altered corticospinal excitability and inhibition of the tibialis anterior during single-leg standing in participants with CAI. Further research is needed to examine the effects of corticospinal maladaptations to motor control of the tibial anterior on postural control performance in those with CAI.

Epithelial-to-mesenchymal transition (EMT) plays an important role in CRC migration, and transforming growth factor-β (TGF-β) works as a dominating cytokine in CRC EMT process. Here, we originally identified RUNX1 as an important factor among TGF-β induced EMT in CRC. We found that RUNX1 was overexpressed with the treatment of TGF-β, accompanied with enhanced cancer cell migration and EMT which was characterized by up-graded N-Cadherin levels. Vice versa, knockdown of RUNX1 attenuated the migration ability of TGF-β induced CRC cells. In addition, decreased expression of N-Cadherin suggested that EMT was also attenuated after knocking down RUNX1. Similar decrease was observed in EMT regulator snail family transcriptional repressor 1 (SNAI1). And the knockdown effect of RUNX1 cannot be reversed by the addition of TGF-β. Moreover, we observed that RUNX1 expression was higher in CRC tumor tissues than in normal epithelial tissues. The enhanced expression was detected in cancer cell nucleus. These results revealed RUNX1 could regulate colorectal cancer migration via TGF-β signaling pathway, and RUNX1 might serve as a potential target for preventing CRC metastasis.The rise of antibiotic failure poses a severe threat to global health. There is growing concern that this failure is not solely driven by stable antibiotic resistance but also by a subpopulation of transiently non-growing, antibiotic tolerant bacteria. These 'persisters' have been proposed to seed relapsing infections, an important clinical outcome of treatment failure - although definitive evidence for this direct link remains elusive. Recent advances in the field have revealed the complex nature of intra-host persisters which drive their high adaptability through biosynthetic activity. These features of persisters contribute to evolution of antimicrobial resistance and modulation of host immune responses, despite clinically efficacious treatment.Volatile thiols are very strong-smelling molecules that can impact the aroma of numerous beverages. Several thiols and thiol precursors have been reported previously in different plants used as raw material for beverages, some of which are fermented. We focused on thiols in beverages and their release mechanisms from precursors during processing. Volatile thiols in beverages can be classified aslow molecular weight volatile thiols (e.g. H2S, methanethiol) which impact the smell negatively, and volatile thiols with higher boiling points that contribute positively to the aroma profile. read more The first part of this review is devoted to volatile thiols, without considering small malodorous molecules. The second part deals with thiol precursors and the different release mechanisms induced by processing (e.g. extraction, roasting or fermentation) and by the growing methods (e.g. viticulture), which can impact on amounts of thiols and their precursors.The epitopes of the major allergen of pine nut, Pin p 1, were analyzed using a peptide library and sera from patients with clinical allergy to pine nut in order to deepen into the allergenic characteristics of Pin p 1. Analyses of epitope similarities and epitopes location in a 3D-model were also performed. Results showed that three main regions of Pin p 1 containing 5 epitopes were recognized by patient sera IgE. The epitopes of Pin p 1 had important similarities with epitopes of allergenic 2S albumins from peanut (Ara h 2 and 6) and Brazil nut (Ber e 1). The epitopes of Pin p 1 were found in α-helices and coils in the 3D protein structure. Interestingly, all epitopes were found to be well-exposed in the protein surface, which suggests facile access for IgE-binding to the structure of Pin p 1 which is known to be highly resistant.This study present the effects of different pre-treatment maceration techniques (microwave, thermo-maceration, and enzymatic treatment) on the content of phenolic compounds (by UPLC-PDA) and their redox potential by cyclic voltammetry (CV), antioxidant capacity (ABTS radical cation decolorization assay and FRAP as Ferric Reducing Ability of Plasma), and other basic chemical properties of red wine made from cv. Dornfelder. The pre-treatment maceration technique significantly (p less then 0.05) affected the content of total phenolics in Dornfelder must (freshly crushed grapes), with particularly high amounts in the must pre-treated by microwaves (4344.0 mg/100 mL), and the lowest in the must pre-treatment by thermo-maceration (2979.8 mg/100 mL). A positive correlation was found between the content of total phenolics and antioxidant activity (R = 0.69 and 0.52 by ABTS and FRAP assay, respectively) and individual groups of polyphenols (for ABTS assay with anthocyanins, flavonols, flavan-3-ols, respectively R = 0.60, 0.64 and 0.66, while for FRAP method only for anthocyanins R = 0.79). The highest antioxidant activity was also determined for the variant with microwave pre-treatment (must 3.31 mM and 3.05 mM Trolox/100 mL for ABTS and FRAP assay, respectively). Following the fermentation and maturation, the amount of polyphenols decreased. No thermal pre-treatment maceration methods gave lighter or redder must. After winemaking process all the samples were characterized by less red and more yellow shade.
