Severe COVID-19 developed preferentially in patients with underlying compromised immunity and was not associated with initial virus levels. Higher SARS-CoV-2 RNA levels in severe cases were apparently a result of impaired immune control associated with dysregulation of inflammation.
We tested polyplexes of a diblock polymer containing a pH-responsive, endosomolytic core (dimethylaminoethyl methacrylate and butyl methacrylate; DB) and a zwitterionic Poly (methacryloyloxyethyl phosphorylcholine) (PMPC) corona for the delivery of plasmid DNA (pDNA) to glioblastoma cells.

We studied the physicochemical characteristics of the DNA polyplexes such as particle hydrodynamic diameter and surface potential. Cytocompatibility of free PMPC-DB polymer and pDNA polyplexes with U-87MG and U-138MG glioma cell lines were evaluated using the ATP assay. The transfection activity of luciferase pDNA polyplexes was measured using a standard luciferase assay. Anti-proliferative, apoptotic, and cell migration inhibitory activities of PMPC-DB/Interferon-beta (IFN-β1) pDNA polyplexes were examined using ATP assay, flow cytometry, and wound closure assay, respectively.

PMPC-DB copolymer condensed pDNA into nanosized polyplexes. DNA polyplexes showed particle diameters ranging from ca. 100-150nm with narrow polydispersity indices and near electroneutral zeta potential values. PMPC-DB/Luciferase pDNA polyplexes were safe and showed an 18-fold increase in luciferase expression compared to the gold standard PEI polyplexes in U-87MG cells. PMPC-DB/IFN-β1 polyplexes induced apoptosis, demonstrated anti-proliferative effects, and retarded cell migration in glioblastoma cells.

The results described herein should guide the future optimization of PMPC-DB/DNA delivery systems for in vivo studies.

Interestingly, opioid withdrawal alone can produce symptoms similar to those of PTSD. Despite this association, the neural mechanisms underlying the relationship of opioid abuse, withdrawal, and PTSD is poorly understood. Our laboratory has investigated the neurobiological underpinnings of stress-enhanced fear learning (SEFL), an animal model of PTSD-like symptoms. We have previously shown that, in SEFL, a severe footshock induces an increase in dorsal hippocampal (DH) interleukin-1β (IL-1β), and subsequent fear learning is blocked by DH IL-1 receptor antagonism (IL-1RA). Given that opioids and stress engage similar neuroimmune mechanisms, the present experiments investigate whether the same mechanisms drive heroin withdrawal to induce a PTSD-like phenotype. First, we tested the effect of a chronic escalating heroin dose and withdrawal regimen on fear learning and found it produces enhanced future fear learning. Heroin withdrawal also induces a time-dependent, region-specific increase in IL-1β and glial fibrillary acidic protein (GFAP) immunoreactivity within the dentate gyrus of the DH. IL-1β was significantly colocalized with GFAP, indicating astrocytes may be involved in increased IL-1β. Moreover, intra-DH infusions of IL-1RA 0, 24, and 48 h into heroin withdrawal prevents the development of enhanced fear learning but does not alter withdrawal-induced weight loss. Collectively, our data suggests heroin withdrawal is sufficient to produce enhanced fear learning, astrocytes may play a role in heroin withdrawal-induced IL-1β, and DH IL-1 signaling during withdrawal mediates the development of heroin withdrawal-enhanced fear learning.
Information regarding the use of lung ultrasound (LUS) in patients with Coronavirus disease 2019 (COVID-19) is quickly accumulating, but its use for risk stratification and outcome prediction has yet to be described. We performed the first systematic and comprehensive LUS evaluation of consecutive patients hospitalized with COVID-19 infection, in order to describe LUS findings and their association with clinical course and outcome.

Between 21/03/2020 and 04/05/2020, 120 consecutive patients admitted to the Tel Aviv Medical Center due to COVID-19, underwent complete LUS within 24h of admission. A second exam was performed in case of clinical deterioration. LUS score of 0 (best)-36 (worst) was assigned to each patient. LUS findings were compared with clinical data.

The median baseline total LUS score was 15, IQR [7-20]. CHR2797 Baseline LUS score was 0-18 in 80 (67%) patients, and 19-36 in 40 (33%) patients. The majority had patchy pleural thickening (n = 100; 83%), or patchy subpleural consolidations (n = 93; 78mortality. link2 Routine use of LUS may guide patients' management strategies, as well as resource allocation in case of surge capacity.
Hospitalized patients with COVID-19, at all clinical grades, present with pathological LUS findings. Baseline LUS score strongly correlates with the eventual need for invasive mechanical ventilation and is a strong predictor of mortality. Routine use of LUS may guide patients' management strategies, as well as resource allocation in case of surge capacity.
Delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (SAH) has been identified as an independent predictor of poor outcome in numerous studies.

To investigate the potential protective role of inhalational anesthetics against angiographic vasospasm, DCI, and neurologic outcome in SAH patients.

After Institutional Review Board approval, data were collected retrospectively for SAH patients who received general anesthesia for aneurysm repair between January 1st, 2010 and May 31st, 2018. Primary outcomes were angiographic vasospasm, DCI, and neurologic outcome as measured by modified Rankin scale at hospital discharge. Univariate and logistic regression analysis were performed to identify independent predictors of these outcomes.

The cohort included 390 SAH patients with an average age of 56±15(mean±SD). Multivariate logistic regression analysis identified inhalational anesthetic only technique, Hunt-Hess grade, age, anterior circulation aneurysm and average intraoperative mean blood prive effect against DCI. When coupled with similar results from preclinical studies, our data suggest further investigation into the impact of inhalational anesthetic conditioning on SAH patients, including elucidating the most effective dosing regimen, defining the therapeutic window, determining whether a similar protective effect against early brain injury, and on long-term neurological outcome exists.
Tripartite motif-containing (TRIM)21 is reported to be associated with the regulation of immune response in gut mucosa. Here we studied the underlying mechanisms of TRIM21 in the pathogenesis of colitis-associated cancer (CAC).

We analyzed TRIM21 expression in tumor tissues from patients with colorectal cancer (CRC) and ulcerative colitis (UC)-associated cancer by immunohistochemistry and real-time polymerase chain reaction and established a CAC model in TRIM21-∕- and wild type mice by azoxymethane (AOM) and dextran sodium sulfate (DSS). Associated gene expression of tumor cell proliferation, adhesion, tissue remodeling and angiogenesis, and inflammatory cytokines were examined in normal colon and CAC by immunohistochemistry and real-time polymerase chain reaction.

Expression of TRIM21 was found to be decreased in tumor tissues from patients with CRC and UC-associated cancer than that in controls, and TRIM21-∕- deficiency promoted AOM/DSS-induced CAC, characterized by more weight loss and multiple, larg1 may serve as a novel therapeutic target for CAC therapy.
Mucosal healing has been associated with long-term response to therapy for Crohn disease (CD). However, little is known about the significance of terminal ileum (TI) transmural thickness in predicting clinical outcomes.

In this retrospective observational cohort study, we examined the association of an index ultrasonographic assessment of TI thickness during the maintenance phase and the subsequent clinical outcome of CD in a cohort of patients treated with infliximab (IFX). Treatment failure was defined as treatment discontinuation because of lack of efficacy, a need for dose escalation, or surgery. Clinical response was defined as treatment continuation in the absence of any of the aforementioned failure criteria.

Sixty patients with CD receiving IFX therapy were included in the study. The patients were followed for a median of 16 months (5-24 months) after an index intestinal ultrasound. Thirty-eight patients (63.3%) maintained response to the therapy and 22 patients (36.6%) failed the treatment, with a mean follow up of 10.5 months (6.5-17 months) vs 9.25 months (1-10.25 months), respectively. On univariate analysis, the only variables differing between treatment response and failure were a TI thickness of 2.8 vs 5 mm (P < 0.0001) and an IFX trough level of 6.6 vs 3.9 µg/mL (P = 0.008).On multivariable analysis, only a small bowel thickness of ≥4 mm was associated with the risk of treatment failure (odds ratio, 2.9; 95% CI, 1.49-5.55; P = 0.002).

Our findings suggest that transmural thickness of ≥4 mm can predict subsequent treatment failure in patients with CD treated using IFX, indicating transmural thickness <4 mm as a potential novel valuable therapeutic target.

This exotic armored scale insect reduces host plant health and function, and often requires insecticide use, which poses risks to nontarget organisms. While the use of Ilex (Aquifoliales Aquifoliaceae) and Camellia (Ericales Theaceae) spp. as landscape ornamentals for aesthetic function is firmly established, we have a poor understanding of species-level susceptibility to F. theae. Additionally, two species, Ilex vomitoria Ait. and Camellia sinensis (L.) O. Kuntze are emerging tisane- and tea-producing commodities in the region, respectively. We propose that these consumable plants may be well-suited alternatives to their traditionally used ornamental congeners in residential landscapes where they may provide enhanced ecosystem services. However, the potential impact of key pests, like F. theae, on these species should be evaluated to anticipate pest pressure that may undermine or offset benefits. link3 In this study, we examine six species within the known host range of tea scale, comparing nonnative I. cornuta Lindl. 'Dwarf Burford,' C. japonica L., C. sasanqua Thunb., and C. sinensis, along with native I. opaca Ait. and I. vomitoria. We found that plant species show a wide range of susceptibility to F. theae and associated damage, with the two native Ilex species and tea-producing C. sinensis displaying the least susceptibility. By reducing the impact of a key pest and considering other ecosystem service traits, these results may help guide more sustainable plant selection decisions where the goal is to integrate native and edible plants into residential landscapes.
