The proper functions of tissues depend on the ability of cells to withstand stress and maintain shape. Central to this process is the cytoskeleton, comprised of three polymeric networks F-actin, microtubules, and intermediate filaments. #link# Intermediate filament proteins are among the most abundant cytoskeletal proteins in cells; yet they remain some of the least understood. Their structure and function deviate from those of their cytoskeletal partners, F-actin and microtubules. Intermediate filament networks show a unique combination of extensibility, flexibility and toughness that confers mechanical resilience to the cell. Vimentin is an intermediate filament protein expressed in mesenchymal cells. This review highlights exciting new results on the physical biology of vimentin intermediate filaments and their role in allowing whole cells and tissues to cope with stress.
Relatively poor survival and differentiation performance of umbilical cord mesenchymal stem cells (ucMSCs) limits its application of transplantation. The purpose of this study was to investigate the combined effect of ucMSCs and tetramethylpyrazine (TMP) on the histological therapy of ischemia stroke.
Using a middle cerebral artery occlusion (MCAO) model, we sought to determine the therapeutic effects of ucMSCs combined with TMP on ischemic stroke in rats. 1 × 10
ucMSCs was intracerebral transplanted after 24 hours and TMP (50 mg/kg) was injected intraperitoneally every day. After 7 days, the brain tissues were subjected to infarct weight measurement and preparation for 2,3,5-triphenyltetrazolium chloride (TTC) staining, HE staining, and immunohistochemical analysis.
The results showed that TMP combined with ucMSCs treatment significantly decreased the neurological deficit score, as well as the cerebral infarct ratio (from 16.33±3.35 to 7.67±1.19%) compared to TMP or ucMSCs treated alone. Moreover, TMP+ucMSCs treatment improved the morphological architecture of the infarct zone, dramatically up-regulated the expression of α-tubulin and nestin, and down-regulated GFAP and IL-1 expression.
These data suggest that ucMSCs combined with TMP are able to exert therapeutic effects following ischemic injury by improving neurogenesis, inhibiting inflammation, and ameliorating histological damage. This may therefore be a promising future treatment for ischemic stroke.

Low-income women using prenatal care have shared concerns as well as unique needs not met by traditional prenatal care. Our objective was to explore user ideas on addressing unmet needs driving unscheduled care utilization and use findings to inform interventions to improve perinatal outcomes.
We performed a secondary analysis of qualitative interviews among purposively sampled, Medicaid-insured pregnant women with varied degrees of unscheduled care utilization. Interviews explored barriers and facilitators of health and ideas for improvement in care delivery, with a focus on the potential role of community health workers and social support. We extracted material on participants' perceived gaps and ideas, used modified grounded theory to develop general and subset themes by study group, and then mapped themes to potential intervention features.
We identified intervention targets in three thematic domains social support, care delivery, and access, noting sub-group differences. Participants with four or more unscheduled visits during pregnancy ("Group 1") wanted individualized help navigating resources, coaching, and peer support, while participants with a first unscheduled care visit after 36 weeks of pregnancy ("Group 2) wanted these services to be optional. Group 1 participants wanted flexible appointments, less wait time, discharge education and improved communication with providers, while Group 2 participants sought stable insurance coverage.
Findings suggest acceptable approaches to improve social support, care delivery, and access via stratified, targeted interventions.
Targeted interventions to improve prenatal care that incorporate user ideas and address unique unmet needs of specific subgroups may improve perinatal outcomes.

III.T2*-weighted gradient-echo sequences count among the most widely used techniques in neuroimaging and offer rich magnitude and phase contrast. The susceptibility effects underlying this contrast scale with B0, making T2*-weighted imaging particularly interesting at high field. High field also benefits baseline sensitivity and thus facilitates high-resolution studies. However, enhanced susceptibility effects and high target resolution come with inherent challenges. Relying on long echo times, T2*-weighted imaging not only benefits from enhanced local susceptibility effects but also suffers from increased field fluctuations due to moving body parts and breathing. High resolution, in turn, renders neuroimaging particularly vulnerable to motion of the head. This work reports the implementation and characterization of a system that aims to jointly address these issues. It is based on the simultaneous operation of two control loops, one for field stabilization and one for motion correction. The key challenge with this approach is that the two loops both operate on the magnetic field in the imaging volume and are thus prone to mutual interference and potential instability. This issue is addressed at the levels of sensing, timing, and control parameters. Performance assessment shows the resulting system to be stable and exhibit adequate loop decoupling, precision, and bandwidth. Simultaneous field and motion control is then demonstrated in examples of T2*-weighted in vivo imaging at 7T.Glucuronoxylomannan (AAPS) from the edible wood ear mushroom Auricularia auricula-judae has been demonstrated to exhibit immunostimulatory properties through its binding to TLR4. However, the mechanisms of immune modulation by AAPS in mammalian cells remains unclear. link2 In the present study, we demonstrated that AAPS induced immunostimulatory effects were regulated by reactive oxygen species, mitogen-activated protein kinases, protein kinase C-α and NF-κB. selleck compound increased the phagocytosis and bactericidal activity of macrophages. In lipopolysaccharide-activated macrophages, AAPS induced endotoxin tolerance like effect characterized by the downregulation of nitric oxide, interleukin-6 and TNF-α via the downregulation of NF-κB activation. Our findings provide firm scientific evidences for the immunoenhancing properties of wood ear mushroom, and the potential of AAPS to be strong candidates for the development of new carbohydrate-based nutraceutical supplements in the management of immunity related disorders in the future.Alzheimer's disease (AD) is one of the most devastating neurodegenerative diseases without effective therapies. Immunotherapies using antibodies to lower assembled Aβ provide a promising approach and have been widely studied. Anti-amyloid antibodies are often selective to amyloid conformation, and the lack of amyloid-antibody structural information limits our understanding of these antibodies' conformation selection. Gantenerumab and crenezumab are two anti-Aβ antibodies that bind multiple forms of Aβ with different Aβ epitope preferences. Here, using molecular dynamic (MD) simulations, we study the binding of these two antibodies to the Aβ1-40 fibril, whose conformation is derived from an AD patient's brain tissue. We find that gantenerumab recognizes the Aβ1-11 monomer fragment only at slightly lower pH than the physiological environment where His6 of Aβ1-11 is protonated. Both gantenerumab and crenezumab bind with integrated Aβ fibril rather than binding to monomers within the fibril. Gantenerumab preferentially binds to the N-terminal region of the Aβ1-40 fibril, and the binding is driven by aromatic interactions. Crenezumab can recognize the N-terminal region, as well as the cross-section of the Aβ1-40 fibril, indicating its multiple binding modes in Aβ fibril recognition. These results demonstrate conformation-dependent interactions of antibody-amyloid recognition.
Describe outcomes among preterm infants diagnosed with single-vessel primary pulmonary vein stenosis (PPVS) initially treated using conservative management (active surveillance with deferral of treatment).
Retrospective cohort study at a single, tertiary-center (2009-2019) among infants <37 weeks' gestation with single-vessel PPVS. Infants were classified into two categories disease progression and disease stabilization. Cardiopulmonary outcomes were examined, and a Kaplan-Meier survival analysis performed.
Twenty infants were included. Compared to infants in the stable group (0/10, 0%), all infants in the progressive group had development of at least severe stenosis or atresia (10/10, 100%; P < 0.01). Severe pulmonary hypertension at diagnosis was increased in the progressive (5/10, 50%) versus the stable group (0/10, 0%; P = 0.03). Survival was lower among infants in the progressive than the stable group (log-rank test, P < 0.01).
Among preterm infants with single-vessel PPVS, risk stratification may be possible, wherein more targeted, individualized therapies could be applied.

To describe risk and risk factors of epilepsy after hospitalization for brain infection in adults in Sweden.
This was a matched retrospective cohort study based on the comprehensive National Patient and Cause of Death Registers. All individuals age >18 without prior epilepsy who received inpatient care in 2000-2010 for a brain infection were included, with 3 age- and sex-matched unexposed controls per exposed individual (n = 12,101 exposed and 36,228 controls). Kaplan-Meier risks of epilepsy after different brain infections were calculated and risk factors identified by Cox regression. Patients were followed until the end of 2017.
The 10-year risk of epilepsy was 5.9% (95% confidence interval [CI] 5.5-6.3) in cases and 1.2% (95% CI 1.0-1.4) in controls 1.7% (95% CI 0.7-2.7) after tick-borne encephalitis, 4.1% (95% CI 3.3-4.9) after bacterial meningitis, 26.0% (95% CI 21.5-30.5) after herpes simplex virus encephalitis, and 30.2% (95% CI 27.1-33.3) after brain abscess. In Cox regression, seizure during the index admission and mechanical ventilation were epilepsy risk factors.
Epilepsy is common after several types of brain infections in adults. The type of infection, its severity, and propensity to cause seizures in the acute phase influence the risk of subsequent epilepsy.
This study provides Class II evidence that in adults, brain infection is associated with an increased risk of subsequent epilepsy.

Elderly, frail patients are often excluded from clinical trials so there is lack of data regarding optimal management when they present with symptomatic coronary artery disease (CAD).
The aim of this observational study was to evaluate an unselected elderly population with CAD for the occurrence of frailty, and its association with quality of life (QoL) and clinical outcomes.
Consecutive patients aged ≥80 years presenting with CAD were prospectively assessed for frailty (Fried frailty phenotype (FFP), Edmonton frailty scale (EFS)), QoL (Short form survey (SF-12)) and comorbidity (Charlson Comorbidity Index (CCI)). Patients were re-assessed at 4 months to determine any change in frailty and QoL status as well as the clinical outcome.
One hundred fifty consecutive patients with symptomatic CAD were recruited in the study. The mean age was 83.7±3.2 years, 99 (66.0%) were men. link3 The clinical presentation was stable angina in 68 (45.3%), the remainder admitted with an acute coronary syndrome including 21 (14.
