Beauveria bassiana is a critical entomopathogenic fungus for pest biocontrol, whose efficiency depends on fungal development and stress resistance. Unlike its revealed location in plasma membrane patches in other organisms, B. bassiana Sur7 specifically localized in vacuoles. This vacuolar Sur7 was previously demonstrated to affect stress tolerance, hyphal development and virulence. There, however, remain more mechanistic details to be explored. In this study, transcriptomics and metabolomics were applied to investigate the mechanism of vacuolar Sur7. Analyses of transcriptomics and metabolomics displayed many differentially expressed genes and abundant metabolites in response to Sur7 loss, respectively. Together with genes associated with vacuolar biofunction (including transportation and hydrolysis), the altered metabolites contributed to cell wall construction and stress resistance. Particularly, an N-acetylglucosamine-associated Brg1/Nrg1 pathway was enriched and partially affected by Sur7. Absence of Sur7 changed the expression level of Brg1/Nrg1 pathway-related transcript factors, which interfered with downstream phenotype of sporulation. In addition, Sur7 was involved in the accumulation of sphingoid bases, which may affect sphingolipid-related signaling pathway. Although experimental evidence is further required, our studies provide a preliminary framework for future exploring the regulatory mechanism of Sur7, and give a new version of metabolic agency connecting Sur7 and downstream signaling pathway.

Superior vena cava (SVC) occlusion in dialysis patients is a serious complication that can cause SVC syndrome and vascular access dysfunction. While endovascular therapy has advanced to become the first line of treatment, open surgical treatment may still be needed occasionally. However, no long term outcome data has been previously reported.

We performed a retrospective review of 5 dialysis patients treated with bypass graft to the right atrium from 2012 to 2014. Four patients had severe dysfunction of their upper arm dialysis access as well as superior vena cava syndrome, and one patient with a femoral tunneled dialysis catheter (TDC) had SVC occlusion. None of the patients were candidates for lower extremity access creation or peritoneal dialysis (PD). Three patients underwent a left brachiocephalic-right atrial bypass and 2 underwent a bypass from the cephalic fistula to the right atrium.

All procedures were technically successful and maintained function of the arteriovenous fistulas or allowed creassful in maintaining function of already existing vascular access or new ones. Long term secondary patency can be achieved but requires strict follow up and a proactive endovascular strategy to treat lesions in the access and or the bypass graft.

The novel acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic imposed a national lockdown at the beginning of 2020. People faced social distancing, being forced to stay at home. Peripheral arterial disease (PAD) typically influences life habits and psycho-social relationship. It is now questionable how PAD can be affected by changes in lifestyle imposed by the Sars-CoV-19 Pandemic. This study's main objective is to evaluate how the limitations of social behavior set by Sars-CoV-19 Pandemic impact the perception and evolution of the disease in a group of patients with a diagnosed PAD.

The changes in the in the perception and the evolution of the PAD were evaluated by comparing results of a modified VascuQol-6 quality of life (QoL) survey referring to the time frame defined "No-Sars-CoV-2 period" (from July to December 2019) with results referring to the time frame defined "Sars-CoV-2 period" (from January to June 2020). An overall score (range 4-60) was calculated, and a comparison between the t1). The ROC curve built to analyze the relation between Delta-score and the need for revascularization identifies a cut-off > 8.5 (Area Under the Curve 0.5436; CI 95% 0.4252 to 0.6620) with a sensitivity and specificity respectively of 52.6% (CI 95% 37.26-67.52%) and 65.6% (CI 95% 53.40-76.08%).

Patients with PAD were significantly hit by all the restrictions and the social limitations imposed to reduce the Sars-CoV-19 virus diffusion. Our study confirms that the perception and the evolution of PAD were significantly affected during the "Sars-CoV-2 period".

Acute aortic thrombosis and floating aortailiac thrombus are infrequent clinical conditions with high morbidity and mortality rates. It was observed that; SARS-CoV-2 coronavirus disease (Covid-19) caused a hyperinflammation and hyperimmune state and these conditions can result in a hypercoagulation and eventually thrombotic events might occur.

Here we presented two covid-19 positive patients with rare aortic thrombotic events.

Two patients underwent emergent diagnostic tests including computerized tomographic angiography. Total aortic thrombosis just below the renal arising point was evaluated in one patient, and aortic floating thrombus was evaluated in other patient. But despite initial medical therapies, the clinical conditions of the cases worsened and both patients died while on medical therapy before planned surgical intervention applied.

Covid-19 is not only the disease of lungs and inflammatory system also the disease of coagulation and vascular system. Aortic thrombosis is rare and must be kept in mind in Covid-19 patients with peripheral circulation impairment.

Crescendo transient ischemic attack is an accepted indication for urgent carotid endarterectomy. COVID-19 is associated with severe thromboembolic complications. We report the case of a 61-year-old man who developed, 2 weeks after the diagnosis of COVID-19, crescendo transient ischemic attack, complicating a large intraluminal floating thrombus within the right common carotid artery. A carotid thromboendarterectomy under local anesthesia, with patch closure was immediately performed without complications. We conducted a literature review to identify cases of common carotid artery thrombus related to COVID-19. Carotid free-floating thrombus in the common carotid artery is exceptional. However, since the beginning of the COVID-19 pandemic, 15 cases have been published.Clostridioides (C.) difficile is clinically highly relevant and produces several AB-type protein toxins, which are the causative agents for C. difficile-associated diarrhea and pseudomembranous colitis. Treatment with antibiotics can lead to C. difficile overgrowth in the gut of patients due to the disturbed microbiota. C. difficile releases large Rho/Ras-GTPase glucosylating toxins TcdA and TcdB, which are considered as the major virulence factors for C. difficile-associated diseases. In addition to TcdA and TcdB, C. difficile strains isolated from severe cases of colitis produce a third toxin called CDT. CDT is a member of the family of clostridial binary actin ADP-ribosylating toxins and consists of two separate protein components. The B-component, CDTb, binds to the receptor and forms a complex with and facilitates transport and translocation of the enzymatically active A-component, CDTa, into the cytosol of target cells by forming trans-membrane pores through which CDTa translocates. In the cytosol, CDTa ADP-ribosylates G-actin causing depolymerization of the actin cytoskeleton and, eventually, cell death. TED-347 In the present study, we report that CDTb exhibits a cytotoxic effect in the absence of CDTa. We show that CDTb causes cell rounding and impairs cell viability and the epithelial integrity of CaCo-2 monolayers in the absence of CDTa. CDTb-induced cell rounding depended on the presence of LSR, the specific cellular receptor of CDT. The isolated receptor-binding domain of CDTb was not sufficient to cause cell rounding. CDTb-induced cell rounding was inhibited by enzymatically inactive CDTa or a pore-blocker, implying that CDTb pores in cytoplasmic membranes contribute to cytotoxicity.

In the United States, Black women are 3 to 4 times more likely to die from childbirth and have a 2-fold greater risk of maternal morbidity than their White counterparts. This disparity is theorized to be related to differences in access to healthcare or socioeconomic status. Military service members and their dependents are a diverse community and have equal access to healthcare and similar socioeconomic statuses.

This study hypothesized that universal access to healthcare, as seen in the military healthcare system, leads to similar rates of maternal morbidity regardless of race or ethnic background.

A retrospective cohort study included data from the inaugural National Perinatal Information Center special report comparing indicators of severe maternal morbidity by race. National Perinatal Information Center data from participating military treatment facilities in the Department of Defense performing more than 1000 deliveries annually from April 1, 2018, to March 31, 2019, were included. Using this convare system do not explain the healthcare disparities seen regarding maternal morbidity encountered by Black women having children in the United States. This study identifies healthcare disparities in severe maternal morbidity among active duty service members and their families. Further studies to assess causes such as systemic racism (including implicit and explicit medical biases) and physiological factors are warranted.

These changes in expression are controlled by transcription factors that gain access to discrete cis-regulatory elements in the genome, allowing them to activate gene expression. Although nucleosomes present barriers to transcription factor occupancy, pioneer transcription factors have unique properties that allow them to bind DNA in the context of nucleosomes, define cis-regulatory elements, and facilitate the subsequent binding of additional factors that determine gene expression. In this capacity, pioneer factors act at the top of gene-regulatory networks to control developmental transitions. Developmental context also influences pioneer factor binding and activity. Here we discuss the interplay between pioneer factors and development, their role in driving developmental transitions, and the influence of the cellular environment on pioneer factor binding and activity.
