Tissue injury results in the release of inflammatory mediators, including a cascade of nociceptive substances, which contribute to development of hyperalgesia. In addition, during this process endogenous analgesic substances are also peripherally released with the aim of controlling the hyperalgesia. Thus, the present study aimed to investigate whether inflammatory mediators TNF-α, IL-1β, CXCL1, norepinephrine (NE) and prostaglandin E2 (PGE2) may be involved in the deflagration of peripheral endogenous modulation of inflammatory pain by activation of the opioid system. Thus, male Swiss mice and the paw withdrawal test were used. All substances were injected by the intraplantar route. Carrageenan, TNF-α, CXCL-1, IL1-β, NE and PGE2 induced hyperalgesia. Selectives μ (clocinamox), δ (naltrindole) and κ (norbinaltorphimine, nor-BNI) and non-selective (naloxone) opioid receptor antagonists potentiated the hyperalgesia induced by carrageenan, TNF-α, CXCL-1 and IL1-β. In contrast, when the enzyme N-aminopeptidase involved in the degradation of endogenous opioid peptides was inhibited by bestatin, the hyperalgesia was significantly reduced. In addition, the western blotting assay indicated that the expression of the opioid δ receptor was increased after intraplantar injection of carrageenan. The data obtained in this work corroborate the hypothesis that TNF-α, CXCL-1 and IL-β cause, in addition to hyperalgesia, the release of endogenous substances such as opioid peptides, which in turn exert endogenous control over peripheral inflammatory pain.The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which emerged in December 2019 and caused the coronavirus disease 2019 (COVID-19) pandemic, took the world by surprise with an unprecedented public health emergency. MT-802 purchase Since this pandemic began, extraordinary efforts have been made by scientists to understand the pathogenesis of COVID-19, and to fight the infection by providing various preventive, diagnostic and treatment opportunities based on either novel hypotheses or past experiences. Despite all the achievements, COVID-19 continues to be an accelerating health threat with no specifically approved vaccine or therapy. This review highlights the recent advances in COVID-19 infection, with a particular emphasis on nanomedicine applications that can help in the development of effective vaccines or therapeutics against COVID-19. A novel future perspective has been proposed in this review based on utilizing polymersome nano-objects for effectively suppressing the cytokine storm, which may reduce the severity of COVID-19 infection.
Calcium accumulation and fibrotic activities are principal mechanisms for calcific aortic valve disease (CAVD). Active complement products are observed in human stenotic aortic valves. Runt-related transcription factor 2 (Runx-2) is involved in tissue calcification. We hypothesized that complement up-regulate Runx-2 to induce pro-fibrogenic change in human aortic valve interstitial cells (AVICs).

AVICs were isolated from 6 normal and 6 CAVD donor valves. Cells were treated with complement cocktails. Pro-fibrogenic activities and associated signaling molecules were analyzed by Western blot assay and collagen staining.

Complement time and dose dependently enhanced pro-fibrogenic activities in AVICs, and complement exposure also induced total collagen deposition in AVICs. Complement induced pro-fibrogenic responses were associated with increased Runx-2 expression and phosphorylation of ERK1/2. Genetic silencing of Runx-2 decreased both MMP-9 and collagen I levels. Pharmacological inhibition of ERK1/2 decreased complement mediated MMP-9, collagen I and Runx-2 expression as well as total collagen deposition in human AVICs. Further, treating AVICs with heat-deactivated complement resulted in reduced MMP-9, collagen I and Runx-2 levels compared to active complement treatment.

Complement induced pro-fibrogenic activities in AVICs by activation of ERK1/2 mediated Runx-2 signaling pathways. This study demonstrates a potential role for complement-mediated CAVD pathogenesis, establishing a possible therapeutic target to limit CAVD progression.

Electrical Storm is a life-threatening condition that affects up to 20% of patients with ICDs. In this small retrospective study, we report our results with left video-assisted thoracoscopic sympathectomy/ganglionectomy (VATSG) to treat refractory electrical storm in low ejection fraction patients who were not candidates for catheter ablations (CA).

We identified 12 patients who presented with electrical storm and underwent a total of 14 video assisted thoracoscopic sympathectomy/ganglionectomy, including three patients on venoarterial extracorporeal membrane oxygenation (VA ECMO). We reviewed demographic data, survival to discharge, number of cardioversions (before and after VATSG), need for readmissions, and need for right-sided procedures.

In the 30 days prior to a left VATSG the mean number of shocks was 22.67 for all patients. For the patients who survived to discharge the mean was 3.55 since surgery with a median of zero shocks after a median follow up of 358 days. Six patients have not experienced any further cardioversions since their last VATSG and five have never been readmitted for VT. Two patients had staged bilateral procedures due to recurrences and of those, one never required any further cardioversions.

Limited left VATSG is an appropriate and effective initial treatment for ES patients who are not candidates for CA, including patients on VA ECMO for hemodynamic support.

We created an estimation model for hypothermic circulatory arrest time and analyzed the risk factors for major adverse outcomes in total arch replacement.

This study involved 272 patients who underwent total arch replacement. The estimation model for hypothermic circulatory arrest time was established using multiple linear regression analysis, and the predicted hypothermic circulatory arrest time from this model was analyzed to detect risk factors.

Atrial fibrillation, rupture, malperfusion, saccular aneurysm, cardiopulmonary bypass time, and hypothermic circulatory arrest time were identified as independent risk factors associated with major adverse outcomes. The estimation model for hypothermic circulatory arrest time was established as follows hypothermic circulatory arrest time = 99.3 - 0.19 × age + 0.65 × body mass index + 6.19 × previous cardiac operation + 11.7 × acute dissection + 8.9 × rupture + 0.19 × aortic angulation + 0.15 × length to the distal anastomosis site - 6.17 × total arch replacement surgeon case volume - 3.
