Importantly, we performed a screening of modified nucleosides capable of inducing autophagy and found that 1-methylguanosine (m1G) was sufficient to induce LC3-II levels. Pathophysiologically, defective export of modified nucleosides drastically induced Zika virus replication in an autophagy-dependent manner. In addition, we also found that pharmacological inhibition of ENTs by dilazep significantly induced Zika virus replication. Collectively, our findings highlight RNA-derived modified nucleosides as important signaling modulators that activate autophagy response and indicate that defective export of these modified nucleoside can have profound consequences for pathophysiology.
Frozen embryo transfer (FET) is associated with a higher risk of hypertensive disorders in pregnancy. The objective of the present study is to evaluate the effect of different protocols of endometrial preparation on the risk of these disorders.

We conducted a retrospective cohort study on 594 singleton pregnancies achieved by embryo transfer of single frozen-thawed blastocysts. Women with preexisting risk factors for hypertensive disorders were excluded. selleck chemical Women were divided into two groups according to the endometrial preparation protocol either natural cycle (
 = 495) or programming cycle with hormonal replacement therapy (
 = 97). The primary outcome was the frequency of hypertensive disorders in pregnancy specifically, gestational hypertension and preeclampsia.

No differences emerged between women following the natural cycle and those following the programming cycle in the frequency of gestational hypertension (5
4%) and preeclampsia (1.1
1.2%). No impact emerged also after multivariate analyses.

Women receiving hormonal replacement therapy have the same risk of gestational hypertension and preeclampsia as women following natural cycles when considering low-risk singleton pregnancies.

However, the molecular activities of Atg8 on the phagophore membranes as the physiologically functional lipidated form remain enigmatic. In our recent study, we unveiled the hidden physicochemical activity of lipidated Atg8 toward the membrane. Structural analysis revealed that lipidated Atg8 adopts a preferred orientation on the membrane, contacting the membrane using aromatic residues and at the same time exposing cargo binding pockets to the solvent, enabling this small protein to perturb and transform membranes while recognizing autophagic cargos. The membrane perturbation activity was shown to be essential for efficient autophagosome biogenesis, yet questions on the mechanistic roles of Atg8 remain open.Cytokinesis is the final stage of the cell cycle which separates cellular constituents to produce two daughter cells. Using the fission yeast Schizosaccharomyces pombe we have investigated the role of various classes of proteins involved in this process. Central to these is anillin/Mid1p which forms a ring-like structure at the cell equator that predicts the site of cell separation through septation in fission yeast. Here we demonstrate a direct physical interaction between Mid1p and the endosomal sorting complex required for transport (ESCRT)-associated protein Vps4p, a genetic interaction of the mid1 and vps4 genes essential for cell viability, and a requirement of Vps4p for the correct cellular localization of Mid1p. Furthermore, we show that Mid1p is phosphorylated by aurora kinase, a genetic interaction of the mid1 and the aurora kinase ark1 genes is essential for cell viability, and that Ark1p is also required for the correct cellular localization of Mid1p. We mapped the sites of phosphorylation of Mid1p by human aurora A and the polo kinase Plk1 and assessed their importance in fission yeast by mutational analysis. Such analysis revealed serine residues S332, S523 and S531 to be required for Mid1p function and its interaction with Vps4p, Ark1p and Plo1p. Combined these data suggest a physical interaction between Mid1p and Vps4p important for cytokinesis, and identify phosphorylation of Mid1p by aurora and polo kinases as being significant for this process.Prostate cancer is one of the most common cancer for men worldwide with advanced forms showing supernumerary or clustered centrosomes. Hematological and neurological expressed 1 (HN1) also known as Jupiter Microtubule Associated Homolog 1 (JPT1) belongs to a small poorly understood family of genes that are evolutionarily conserved across vertebrate species. The co-expression network of HN1 from the TCGA PRAD dataset indicates the putative role of HN1 in centrosome-related processes in the context of prostate cancer. HN1 expression is low in normal RWPE-1 cells as compared to cancerous androgen-responsive LNCaP and androgen insensitive PC-3 cells. HN1 overexpression resulted in differential response for cell proliferation and cell cycle changes in RWPE-1, LNCaP, and PC-3 cells. Since HN1 overexpression increased the proliferation rate in PC-3 cells, these cells were used for functional characterization of HN1 in advanced prostate carcinogenesis. Furthermore, alterations in HN expression led to an increase in abnormal to normal nuclei ratio and increased chromosomal aberrations in PC-3 cells. We observed the co-localization of HN1 with γ-tubulin foci in prostate cancer cells, further validated by immunoprecipitation. HN1 was observed as physically associated with γ-tubulin and its depletion led to increased γ-tubulin foci and disruption in microtubule spindle assembly. Higher HN1 expression was correlated with prostate cancer as compared to normal tissues. The restoration of HN1 expression after silencing suggested that it has a role in centrosome clustering, implicating a potential role of HN1 in cell division as well as in prostate carcinogenesis warranting further studies.
Carbapenemase-producing
(CPE) infections have been occasionally described in patients with coronavirus disease-19 (COVID-19). We assess the clinical features and outcome of these infections.

In this retrospective single-centre, case-control study, we included 54 patients with CPE infection 30 case-patients (COVID-19) and 24 controls (non-COVID-19), collected between March and May 2020. We compared the epidemiological, clinical features, and outcome between cases and controls.

CPE infection was more frequent in COVID-19 patients than in controls (1.1
0.5%,
 = .005). COVID-19 patients were younger, had a lower frequency of underlying diseases (
 = .01), and a lower median Charlson score (
 = .002). Predisposing factors such as antimicrobial use, mechanical ventilation, or ICU admission, were more frequent in COVID-19 patients (
 < .05). There were 73 episodes of infection (42 cases and 31 controls) that were more frequently hospital-acquired and diagnosed at the ICU in COVID-19 patients (
 < .001). Urinary tract was the most common source of infection (47.9%), followed by pneumonia (23.3%). The frequency of severe sepsis or shock (
 = .01) as well as the median SOFA score (
 = .04) was higher in cases than in controls.
(80.8%),
(11%) and
(4.1%) were the most common bacteria in both groups (KPC 56.2%, OXA-48 26% and VIM 17.8%). Overall 30-d mortality rate of COVID-19 patients and controls was 30 and 16.7%, respectively (
 = .25).

COVID-19 patients have an increased risk of CPE infections, which usually present as severe, nosocomial infections, appearing in critically-ill patients and associated with a high mortality.

This systematic review and meta-analysis aimed to analyse how the pandemic impacted the system-of-care of out-of-hospital cardiac arrest.Methods We searched PubMed and Embase up to May 31, 2021, for studies comparing out-of-hospital cardiac arrests that occurred during the COVID-19 pandemic versus a non-pandemic period. Survival at hospital discharge or at 30 days was the primary outcome.Results We included 24 studies for a total of 75,952 patients. Out-of-hospital cardiac arrests during COVID-19 pandemic had lower survival (19 studies; 603/11,666 [5.2%] vs. 1320/17,174 [7.7%]; OR =0.54; 95% CI, 0.44-0.65; P = 0.001) and return of spontaneous circulation (4370/24353 [18%] vs. 7401/34510 [21%]; OR =0.64; 95% CI, 0.55-0.75; P  less then  0.001) compared with non-pandemic periods. Ambulance response times (10.1 vs 9.0 minutes, MD =1.01; 95% CI, 0.59-1.42; P  less then  0.001) and non-shockable rhythms (18,242/21,665 [84%] vs. 19,971/24,817 [81%]; OR =1.27; 95% CI, 1.10-1.46; P  less then  0.001) increased. Use of supraglottic airways devices increased (2853/7645 [37%] vs. 2043/17521 [12%]; OR =1.97; 95% CI, 1.42-2.74; P  less then  0.001).Conclusions The COVID-19 pandemic affected the system-of-care of out-of-hospital cardiac arrest, and patients had worse short-term outcomes compared to pre-pandemic periods. Advanced airway management strategy shifted from endotracheal intubation to supraglottic airway devices.Review registration PROSPERO CRD42021250339.Coronary atherosclerosis (CAS) is a major cause of cardiovascular disease. link2 Long non-coding RNAs (lncRNAs) have been implicated as novel biomarkers in coronary artery disease (CAD). APOA1 antisense RNA (APOA1-AS) was proven to show high expression during atherosclerotic development, but no report has uncovered the detailed mechanism of APOA1-AS in CAS. Thus, this paper aims to explore the role of APOA1-AS in CAS. link3 Vascular smooth muscle cells (VSMCs) were treated with oxidized low-density lipoprotein (ox-LDL) to mimic atherosclerosis-like injury. Quantitative real-time PCR (RT-qPCR) and western blot analysis analyzed gene expression. Cell counting kit-8 (CCK-8), wound healing assay, and flow cytometry were implemented to assess the function of APOA1-AS in modulating pathological phenotype of VSMCs. Results demonstrated that APOA1-AS was notably up-regulated in ox-LDL treated VSMCs (ox-LDL-VSMCs). The deficiency of APOA1-AS hindered proliferation and migration and stimulated apoptosis in ox-LDL-VSMCs. Mechanistically, APOA1-AS recruited TATA-box binding protein associated factor 15 (TAF15) protein to stabilized SMAD family member 3 (SMAD3) mRNA and activate the TGF-β/SMAD3 signaling pathway. In conclusion, APOA1-AS contributed to proliferation and migration and repressed apoptosis of VSMCs through TAF15-mediated SMAD3 mRNA stabilization, indicating that APOA1-AS could be a promising target for CAS.Lipid accumulation often leads to lipotoxic injuries to hepatocytes, which can cause nonalcoholic steatohepatitis. The association of inflammation with lipid accumulation in liver tissue has been studied for decades; however, key mechanisms have been identified only recently. In particular, it is still unknown how hepatic inflammation regulates lipid metabolism in hepatocytes. Herein, we found that PA treatment or direct stimulation of STING1 promoted, whereas STING1 deficiency impaired, MTORC1 activation, suggesting that STING1 is involved in PA-induced MTORC1 activation. Mechanistic studies revealed that STING1 interacted with several components of the MTORC1 complex and played an important role in the complex formation of MTORC1 under PA treatment. The involvement of STING1 in MTORC1 activation was dependent on SQSTM1, a key regulator of the MTORC1 pathway. In SQSTM1-deficient cells, the interaction of STING1 with the components of MTORC1 was weak. Furthermore, the impaired activity of MTORC1 via rapamycin treatment or STING1 deficiency decreased the numbers of LDs in cells.
