Despite the improved safety-profile of direct oral anticoagulants (DOACs), bleeding complications remain an important side effect of anticoagulant treatment. Although anticoagulant-specific antidotes are available, an universal anticoagulant reversal agent in case of life-threatening bleeding or emergency surgery is not yet available. Ciraparantag, a synthetic small molecule that inactivates heparins and DOAC, is a promising new reversal agent that has been investigated in phase 2 trials. In this short review we provide an overview of the preclinical and clinical evidence of ciraparantag, and compare strengths and weaknesses of ciraparantag and the currently available anticoagulant reversal strategies.Fast photochemical oxidation of proteins (FPOP) is a hydroxyl radical footprinting approach whereby radicals, produced by UV laser photolysis of hydrogen peroxide, induce oxidation of amino acid side-chains. Mass Spectrometry (MS) is employed to locate and quantify the resulting irreversible, covalent oxidations to use as a surrogate for side-chain solvent accessibility. Modulation of oxidation levels under different conditions allows for the characterisation of protein conformation, dynamics and binding epitopes. FPOP has been applied to structurally diverse and biopharmaceutically relevant systems from small, monomeric aggregation-prone proteins to proteome-wide analysis of whole organisms. This review evaluates the current state of FPOP, the progress needed to address data analysis bottlenecks, particularly for residue-level analysis, and highlights significant developments of the FPOP platform that have enabled its versatility and complementarity to other structural biology techniques.

We aimed to compare the efficacy of δ-tocotrienol with α-tocopherol in the treatment of patients with non-alcoholic fatty liver disease (NAFLD).

Thisstudy wasa double-blinded, active-controlled trial. The patients with NAFLD were randomly assigned to receive either δ-tocotrienol 300mg or α-tocopherol 268mg twice daily for 48 weeks.

The primary endpoints were change from baseline in fatty liver index (FLI), liver-to-spleen attenuation ratio (L/S ratio), and homeostaticmodel assessment for insulin resistance (HOMA-IR) at 48 weeks. Key secondary endpoints were change in markers of inflammation, oxidative stress, and hepatocyte apoptosis. Clinical assessment, biochemical analysis, and computed tomography scan of the liver were conducted at baseline, 24 and 48 weeks.

A total of 100 patients (δ-tocotrienol=50, α-tocopherol=50) were randomized and included in the intention to treat analysis. Compared with baseline, there was a significant improvement (p<.001) in FLI, L/S ratio, HOMA-IR, and serum malondiaweight, inflammation, and apoptosis associated with NAFLD.

Rats were exposed to different concentrations of PM2.5 to investigate the mechanism of short-term exposure-induced lung inflammation. The regulation of PI3K-Akt and DNA methyltransferase 3b (DNMT3b) was assessed by using a PI3K inhibitor and a DNA methyltransferase inhibitor. We found that PM2.5 could decrease interferon-γ (IFN-γ) levels and increase interleukin 4 (IL-4), IL-5 and IL-13 levels in bronchoalveolar lavage fluid (BALF) to promote eosinophil infiltration and eventually lead to allergic pulmonary inflammation. Moreover, the CpG island methylation rate of the IFN-γ promoter and the protein expression of DNMT3b, PI3K and p-Akt were increased in lung tissues after PM2.5 exposure. Both inhibitors reversed the CpG island hypermethylation of IFN-γ. In conclusion, in PM2.5-induced lung injury, the activated PI3K-Akt pathway, via an increase in DNMT3b expression, is involved in CpG hypermethylation of the IFN-γ gene promoter.

This study aimed to investigate the current situation regarding fertility intentions, parenting attitudes, and fear of childbirth among college students in mainland China and the factors related to these variables.

A cross-sectional study SETTING Colleges across China PARTICIPANTS Five hundred and eighty-three college students attending regular institutions of higher education MAIN OUTCOME MEASURES Fertility intentions and fear of childbirth were measured using the Swedish Fertility Awareness Questionnaire and the Childbirth Fear Prior to Pregnancy scale.

Only 38.8% of participants expressed their willingness to have children, and there was a significant difference between male and female students (P < .02). Males regarded having children as more important (P < .01), and females were more concerned about the negative effects of becoming parents, including difficulties in the labor market, having less freedom, and having less money. When deciding whether to have children, factors such as work, economics, and childcare were more important to females. Students who did not want children had higher levels of fear of childbirth than those who wanted children or were unsure (P < .02).

The fertility intentions of college students were not optimistic. In addition to the 2-child Chinese fertility policy, interventions aimed at reducing the cost of raising children, eliminating gender inequality in the workplace, and normalizing childcare institutions might help alleviate conflict between work and childrearing.

It is observed that circular RNA (circRNA) PTTG1 interacting protein (circPTTG1IP) level is notably up-regulated in rheumatoid arthritis (RA) patients by previous study. However, its precise role and working mechanism in RA pathology remain to be clarified.

Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blot assay were carried out to examine RNA and protein expression. Cell proliferation was analyzed by colony formation assay and 5-Ethynyl-2'-deoxyuridine (EdU) assay. Cell motility was assessed by transwell assays and wound healing assay. Flow cytometry (FCM) analysis was performed to assess cell apoptosis rate. Dual-luciferase reporter, RNA immunoprecipitation (RIP), and RNA-pull down assays were conducted to confirm the interaction between microRNA-431-5p (miR-431-5p) and circPTTG1IP or follistatin like 1 (FSTL1). CircPTTG1IP expression was up-regulated in the synovial tissues of RA patients and RA patients-derived fibroblast-like synoviocytes (RA-FLS). CircPTTG1IP absence suppressed the proliferation, migration, and invasion and induced the apoptosis of RA-FLS. CircPTTG1IP negatively regulated the expression of miR-431-5p by directly binding to it in RA-FLS. CircPTTG1IP interference-mediated effects in RA-FLS were largely counteracted by the silence of miR-431-5p. Divarasib clinical trial miR-431-5p directly interacted with the 3' untranslated region (3'UTR) of FSTL1. FSTL1 overexpression largely overturned miR-431-5p accumulation-mediated effects in RA-FLS. CircPTTG1IP positively regulated FSTL1 expression by sponging miR-431-5p in RA-FLS.

CircPTTG1IP absence suppressed RA progression through mediating miR-431-5p/FSTL1 signaling cascade.

Clostridium perfringens (C.perfringens), is a spore-forming and toxin-producing pathogenic Gram-positive rod-shaped bacterium with immense public health/zoonotic concern. Rodents are well-known reservoirs and vectors for a large number of zoonoses and strong links have been recognized between synanthropic rodents and foodborne disease outbreaks throughout the world. To date, no study has been conducted for studying the prevalence of C.perfringens in rodents and shrews. In this study, we investigated faecal samples from free-living rodents and shrews trapped in Meghalaya, a North-eastern hill state of India for the presence of virulent and antimicrobial-resistant C.perfringens.

A total of 122 animals comprising six species of rodents and one species of shrews were trapped Mus musculus (n=15), Mus booduga (n=7), Rattus rattus (n=9), Rattus norvegicus (n=3), Bandicota indica (n=30), Bandicota bengalensis (n=32) and Suncus murinus (n=26). The faecal swabs were collected and processed for the isolation of C.pelence of C.perfringens and its virulence profile and antimicrobial resistance in free-living rodents and shrews. The rodents and shrews can potentially contaminate the food and environment and can infect humans and livestock with multi-drug resistant/virulent Type A and Type C C.perfringens.

Globally, this is the first study to report the prevalence of C. perfringens and its virulence profile and antimicrobial resistance in free-living rodents and shrews. The rodents and shrews can potentially contaminate the food and environment and can infect humans and livestock with multi-drug resistant/virulent Type A and Type C C. perfringens.

Detailed data on clinical characteristics in children with the omicron strain of SARS-COV-2 are limited.

We conducted a retrospective observational study of children with COVID-19 at the National Center for Child Health and Development to evaluate the clinical manifestations during and before the emergence of the omicron variant. Only symptomatic patients without underlying diseases were included. Participants were divided into two temporal groups the "omicron era" (1/2022-2/2022) and the "pre-omicron era," where the delta variant predominated (7/2021-11/2021). The patients were subclassified into an older vaccine-eligible group (aged 12-17 years), a younger vaccine-eligible group (aged 5-11 years), and a vaccine-ineligible group (aged 0-4 years).

We compared 113 patients in the omicron era with 106 in the pre-omicron era. Most patients in both eras had non-severe disease, and no patients required mechanical ventilation or died. Among patients aged 0-4 years, sore throat and hoarseness were more common during the omicron era than the pre-omicron era (11.1% vs. 0.0% and 11.1% vs. 1.5%, respectively). Croup syndrome was diagnosed in all patients with hoarseness. Among patients aged 5-11 years, vomiting was more frequent during the omicron era (47.2%) than during the pre-omicron era (21.7%). Cough and rhinorrhea were less common during the omicron era in patients aged 0-4 and 5-11 years, respectively, than during the pre-omicron era.

In children with COVID-19, clinical manifestations differed between the omicron and pre-omicron eras. In the Omicron era, croup syndrome was more frequent in vaccine-ineligible children.

Failures have been reported across the cancer care continuum in patients with hepatocellular carcinoma (HCC); however, the impact of treatment delays on outcomes has not been well-characterized. We described the prevalence of treatment delays in a racially and ethnically diverse cohort of patients and its association with overall survival.

Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified patients diagnosed with HCC between 2001 and 2015. We performed multivariable logistic regression analysis to identify factors associated with treatment delay (ie, receipt of HCC-directed therapy >3 months after diagnosis). Cox proportional hazards regression analysis with a 5-month landmark was used to characterize the association between treatment delay and overall survival, accounting for immortal time bias.

Of 8450 patients with treatment within 12 months of HCC diagnosis, 1205 (14.3%) experienced treatment delays. The proportion with treatment delays ranged from 6.8% of patients undergoing surgical resection to 21.
