Bisphenol S (BPS) has attracted much attention as an emerging hazardous contaminant due to its endocrine disruption and oncogenic effects. Although white-rot fungi have remarkable bioremediation capabilities for some bisphenols, little is known about their performance in BPS degradation. In this study, the newly discovered Phlebia acerina S-LWZ20190614-6 exhibited high capacity to degrade BPS.

Accumulating evidence indicates that long noncoding RNAs (lncRNAs) play important roles in molecular and cellular biology. Although many algorithms have been developed to reveal their associations with complex diseases by using downstream targets, the upstream (epi)genetic regulatory information has not been sufficiently leveraged to predict the function of lncRNAs in various biological processes. Therefore, we present FunlncModel, a machine learning-based interpretable computational framework, which aims to screen out functional lncRNAs by integrating a large number of (epi)genetic features and functional genomic features from their upstream/downstream multi-omic regulatory networks.

Background: Growing evidence suggests that direct oral anticoagulants (DOACs) may be suitable for cerebral venous thrombosis (CVT). The optimal strategy regarding lead-in parenteral anticoagulation (PA) prior to DOAC is unknown.

Methods: In this post hoc analysis of the retrospective ACTION-CVT study, we compared patients treated with DOACs as part of routine care: those given "very early" DOAC (no PA), "early" (<5 days PA) and "delayed" (5-21 days PA).

, a macrofungal species in the , , is known to enhance the nutritional and bioactive properties of rice through co-fermentation; however, its own secondary metabolites are not well understood. In this study, an integrative analysis of transcriptome and metabolome data revealed that the accumulation of steroids, steroid derivatives, and triterpenoids in peaks during the mid-growth stage, while the genes associated with these metabolites show higher expression levels from the early to mid-growth stages. Weighted gene co-expression network analysis identified several modules containing candidate genes involved in the synthesis of steroids, steroid derivatives, and triterpenoids.

Clinical Problem: Identification, work-up and treatment approach of isolated cortical venous thrombosis (ICVT) in the absence of traditional risk factors.

Case Presentation: A 66-year-old previously well male presenting with two episodes of left-sided spreading sensory symptoms, found to be secondary to ICVT from extrinsic compression by an arachnoid cyst.

Key Teaching Points: Early identification of structural abnormalities causing extrinsic venous compression and ICVT or cerebral venous sinus thrombosis (CVST) is important for alternative treatment options and to avoid unnecessary testing.

Gut flora is considered to modulate lipid transport from the intestine into the bloodstream, and thus may potentially participate in the development of GDM. Although previous studies have shown that the intestinal microbiota influences lipid transport and metabolism in GDM, the precise mechanisms remain elusive. To address this, we used a high-fat diet (HFD)-induced GDM mouse model and conducted 16s rRNA sequencing and fecal metabolomics to assess gut microbial community shifts and associated metabolite changes.

Chronic kidney disease (CKD) is a major public health problem worldwide. When CKD patients progress to the stage of kidney failure, kidney replacement therapy (KRT) or conservative treatment (palliative or non-dialysis treatment) will be needed. The risk prediction models of chronic kidney failure have been developed in recent years.

Background: Unlike other causes of stroke, symptoms in cerebral venous thrombosis (CVT) can be nonspecific at onset with gradual worsening over time. To explore potential opportunities for earlier diagnosis, we analyzed healthcare interactions in the week prior to hospitalization for patients admitted with incident CVT in British Columbia (BC).

Methods: We constructed a population-based cohort (2000-2017) using linked patient-level administrative data to identify patients aged ≥18 diagnosed with CVT in BC.

Article Synopsis
  • The study aimed to provide updated data on cerebral venous thrombosis (CVT) incidence and trends in the U.S. from 2016-2020, assess the impact of COVID-19, and identify factors predicting in-hospital mortality.
  • The incidence of CVT rose significantly from 24.34 to 33.63 per million people per year, while the all-cause in-hospital mortality rate remained stable at 4.9%.
  • Predictors of higher in-hospital mortality included factors like increased age, atrial fibrillation, and infection, with no significant differences in CVT cases or outcomes during the first wave of the COVID-19 pandemic compared to the same period in 2019.

Wood-inhabiting fungi have important economic values as well as playing a major ecological role in forest ecosystem cycles. The Dabie Mountains, at the junction of Henan, Hubei, and Anhui Provinces, Central China, provide an ideal climate and favorable niches for the speciation and diversification of various forms of life including fungi. We studied the species diversity and community phylogenetics of wood-inhabiting basidiomycetous fungi that revealed 175 wood-inhabiting basidiomycetous species, of which 20 represented unidentified species, based on morphological and phylogenetic analyses of 575 specimens collected from ten sampling sites.
