Novel carbon nanodots (nCD-DBC) and nano zero-valent iron composites (nZVI-DBC) were synthesized using date palm waste-derived biochar (DBC). The synthesized materials were analyzed for chemical and structural composition by using FTIR, SEM, XRD, and TGA, and evaluated for their methylthioninium chloride dye (MB) removal efficiency from contaminated aqueous solutions. pH 7.0 was found optimum for the highest MB removal in sorption batch studies. Kinetics sorption of MB onto the sorbents was best described by pseudo-second-order (R2 = 0.93-0.99) and Elovich models (R2 = 0.86-0.97) implying that sorption was being controlled by chemisorption. Langmuir model predicted maximum sorption capacities for nCD-DBC, nZVI-DBC, and DBC were 1558.66, 1182.90, and 851.67 mg g-1, respectively, which correlated with the results of kinetics sorption. Likewise, nCD-DBC yielded the highest partition coefficient (7067 mL g-1), followed by nZVI-DBC (1460 mL g-1), and DBC (930 mL g-1). Post-sorption XRD, FTIR, and SEM analyses depicted the binding of MB onto the sorbents. It was suggested that electrostatic interactions, π-π electron donor-accepter interactions, degradation, and diffusion were responsible for MB removal by the synthesized materials. Therefore, the nCD-DBC, nZVI-DBC, and DBC can potentially be used for scavenging MB dye from contaminated aqueous solutions.Cardiovascular disease is still the leading cause of mortality worldwide. Vascular endothelial dysfunction is viewed as the initial step of most cardiovascular diseases. Many studies have indicated that periodontal pathogens, especially Porphyromonas gingivalis, are closely correlated with vascular endothelial homeostasis, but the function of P. gingivalis and the underlying mechanisms are still elusive. To illuminate the effects and elucidate the mechanisms of P. gingivalis on endothelial structural integrity, we developed P. gingivalis infection models in vivo and in vitro. Endothelial cell proliferation, differentiation and apoptosis were detected. Here, we showed that P. gingivalis can impair endothelial integrity by inhibiting cell proliferation and inducing endothelial mesenchymal transformation and apoptosis of endothelial cells, which reduce the cell levels and cause the endothelium to lose its ability to repair itself. A mechanistic analysis showed that TLR antagonist or NF-κB signalling inhibitor can largely rescue the damaged integrity of the endothelium caused by P. gingivalis, suggesting that TLR-NF-κB signalling plays a vital role in vascular endothelial homeostasis destroyed by P. gingivalis. https://www.selleckchem.com/products/cobimetinib-gdc-0973-rg7420.html These results suggest a potential intervention method for the prevention and treatment of cardiovascular disease.
To evaluate visual outcome and patient satisfaction following Lentis Comfort intraocular lens (IOL) implantation.
This retrospective case series examined 68 eyes of 41 patients (mean age 72.0 ± 8.1 years) who underwent Lentis Comfort (LS-313 MF15, Oculentis GmbH, Berlin, Germany; Santen, Osaka, Japan) implantations. Patients were evaluated for visual acuity (VA) at several distances (0.3, 0.5 and 5 meters), refractive error, defocus curve and contrast sensitivity, in addition to answering a questionnaire on photic phenomena, visual discomfort and patient satisfaction.
Uncorrected visual acuity was 0.05 ± 0.13 (logMAR) for distance, 0.23 ± 0.17 (logMAR) for intermediate, and 0.52 ± 0.20 (logMAR) for near. Defocus curve showed the binocular visual acuity attained was almost 20/20 within the range of +0.5 D to -1.5 D. Contrast sensitivity was within the normal range. The Lentis Comfort IOL tolerated astigmatism to some extent. Patient age could potentially be related to uncorrected visual acuity. Questionnaire results showed almost all patients were satisfied with Lentis ComfortIOL implantation.
Lentis Comfort IOLs provided better visual function at far and intermediate distances.

Germline
pathogenic (P) variants cause Li-Fraumeni syndrome (LFS), an aggressive multitumor-predisposing condition. Due to the implementation of multigene panel testing,
variants have been detected in individuals without LFS suspicion, for example, patients with colorectal cancer (CRC). We aimed to decipher whether these findings are the result of detecting the background population prevalence or the aetiological basis of CRC.
We analysed
in 473 familial/early-onset CRC cases and evaluated the results together with five additional studies performed in patients with CRC (total n=6200). Control population and LFS data were obtained from Genome Aggregation Database (gnomAD V.2.1.1) and the International Agency for Research on Cancer (IARC)
database, respectively. All variants were reclassified according to the guidelines of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology (ACMG/AMP), following the ClinGen
Expert Panel specifications.
P or likeective follow-up of carriers of germline TP53 P variants in the absence of LFS phenotypes will define how surveillance and clinical management of these individuals should be performed.
Injection of a topical anaesthetic has been proved to be helpful with reducing pain after laparoscopic herniorrhaphy. We aimed to assess the effect of bupivacaine lavage on postoperative pain and compare it with diclofenac suppository. In this randomized clinical trial, 60 patients-scheduled for laparoscopic herniorrhaphy-were enrolled and randomized into three groups of 20 each, including diclofenac suppository, bupivacaine lavage, and normal saline as a placebo.The patients were investigated for postoperative pain scores, vomiting, nausea, morphine request, and duration of hospitalization.
In the bupivacaine group, pain levels in recovery room, 4, 8 and 12h after surgery, were significantly lower than diclofenac group; at time points of 16, 20 and 24h after surgery, difference between two groups was not significant. Regarding vomiting and nausea, at time points of 1 and 3h after surgery, results show no significant difference between the groups. Incident of infection, 1h and 1week after the surgery, wasin patients undergoing laparoscopic herniorrhaphy.

Colon cancer is one of the most common cancer worldwide and has a poor prognosis. Through the analysis of transcriptome and clinical data of colon cancer, immune gene-set signature was identified by single sample enrichment analysis (ssGSEA) scoring to predict patient survival and discover new therapeutic targets.
To study the role of immune gene-set signature in colon cancer.
First, RNASeq and clinical follow-up information were downloaded from The Cancer Genome Atlas (TCGA). Immune gene-related gene sets were collected from ImmPort database. Genes and immunological pathways related to prognosis were screened in the training set and integrated for feature selection using random forest. Immune gene-related prognosis model was verified in the entire TCGA test set and GEO validation set and compared with immune cells scores and matrix score.
1650 prognostic genes and 13 immunological pathways were identified. These genes and pathways are closely related to the development of tumors. 13-immune gene-set signature was established, which is an independent prognostic factor for patients with colon cancer. Risk stratification of samples could be carried out in the training set, test set and external validation set. The AUC of five-year survival in the training set and validation set is greater than 0.6. Immunosuppression occurs in high-risk samples. Compared with published models, Riskscore has better prediction effect.
This study constructed 13-immune gene-set signature as a new prognostic marker to predict the survival of patients with colon cancer, and provided new diagnostic/prognostic biomarkers and therapeutic targets for colon cancer.

Don roots have been widely used in folk medicine for treating inflammatory conditions. However, few studies have elucidated compounds that justify their traditional use. This study was conducted to characterize the phytochemical profile and evaluate the in vitro antioxidant capacity, and in vivo anti-inflammatory activity of extracts obtained from B. uniflora roots by comparing an herbal remedy (HR) with the crude hydroalcoholic extract (CHE). In the phytochemical analysis, scopoletin was identified as the marker compound. In quantitative analyses, CHE showed better results than HR. Furthermore, CHE had an effective anti-inflammatory activity. Animals treated with CHE (200 mg/kg) showed an 89.1% and a 73.8% reduction in edema volume after 1 hour of edema induction compared with those treated with negative control and positive control (indomethacin), respectively. These results show that B. uniflora root extracts have promising antioxidant and anti-inflammatory activities, thus corroborating their application in ethnomedicine.The commensal microbiota is a recognized enhancer of arterial thrombus growth. While several studies have demonstrated the prothrombotic role of the gut microbiota, the molecular mechanisms promoting arterial thrombus growth are still under debate. Here, we demonstrate that germ-free (GF) mice, which from birth lack colonization with a gut microbiota, show diminished static deposition of washed platelets to type I collagen compared with their conventionally raised (CONV-R) counterparts. Flow cytometry experiments revealed that platelets from GF mice show diminished activation of the integrin αIIbβ3 (glycoprotein IIbIIIa) when activated by the platelet agonist adenosine diphosphate (ADP). Furthermore, washed platelets from Toll-like receptor-2 (Tlr2)-deficient mice likewise showed impaired static deposition to the subendothelial matrix component type I collagen compared with wild-type (WT) controls, a process that was unaffected by GPIbα-blockade but influenced by von Willebrand factor (VWF) plasma levels. Collectively, our results indicate that microbiota-triggered steady-state activation of innate immune pathways via TLR2 enhances platelet deposition to subendothelial matrix molecules. Our results link host colonization status with the ADP-triggered activation of integrin αIIbβ3, a pathway promoting platelet deposition to the growing thrombus.Papain-like proteases (PLpro) of coronaviruses (CoVs) support viral reproduction and suppress the immune response of the host, which makes CoV PLpro perspective pharmaceutical targets. Their inhibition could both prevent viral replication and boost the immune system of the host, leading to the speedy recovery of the patient. Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the third CoV outbreak in the last 20 years. Frequent mutations of the viral genome likely lead to the emergence of more CoVs. Inhibitors for CoV PLpro can be broad-spectrum and can diminish present and prevent future CoV outbreaks as PLpro from different CoVs have conservative structures. Several inhibitors have been developed to withstand SARS-CoV and Middle East respiratory syndrome CoV (MERS-CoV). This review summarizes the structural features of CoV PLpro, the inhibitors that have been identified over the last 20 years, and the compounds that have the potential to become novel effective therapeutics against CoVs in the near future.
