Anaplastic thyroid carcinoma (ATC) is an extraordinarily aggressive form of thyroid cancer, frequently presenting with locally advanced infiltration or distant metastases at the time of initial diagnosis, thus missing the optimal window for surgical intervention. Consequently, systemic chemotherapy and targeted therapies are vital for improving the prognosis of ATC. However, ATC exhibits significant resistance to conventional treatments, highlighting the need to elucidate the biological mechanisms underlying this drug resistance and identify novel therapeutic targets to overcome it.

Chiral tricyclic 6,5,5-fused rings exhibit structural diversity and possess important biological activities in the synthesis of natural products. However, predicting the possible mechanism and origin of stereoselectivity in these reactions remains a challenge. In this article, we conducted a theoretical investigation into the NHC-catalyzed intramolecular [3 + 2] annulations of ynals to generate tricyclic 6,5,5-fused rings.

Objectives: Hepatitis E virus (HEV) is a global health concern that causes acute hepatitis with severe consequences, particularly in patients with chronic liver disease. Despite the availability of a recombinant hepatitis E vaccine (Hecolin), its safety and immunogenicity in patients with pre-existing liver cirrhosis remain uncertain. This study aimed to assess the safety and immunogenicity of Hecolin in individuals with compensated liver cirrhosis who have chronic hepatitis B (CHB).

Dead algae deposition will change the nutrient transformation on the sediment-water interface. However, the key factors that drive nutrient turnover, particularly the influence of sediment microbiota, remain poorly understood. As a result, this study conducted an 80-day simulated incubation to investigate the effect of different deposition of death algae on microbial communities and functional potentials in sediments.

Proteinaceous wastewater contains various proteins, which can be valorized to biobased volatile fatty acids (VFAs), important substrates for the synthesis of biodegradable plastics, biodiesel, bioelectricity, etc., but the influence of protein type on VFAs has never been documented. It was found that among the five proteinaceous wastewater proteins investigated, ovalbumin and casein produced the most and the least VFAs, respectively.

Monkeypox virus (MPXV) is an important zoonotic pathogenic virus, which poses serious threats to public health. MPXV infection can be prevented by immunization against the variola virus. Because of the safety risks and side effects of vaccination with live vaccinia virus (VACV) strain Tian Tan (VTT), we constructed two gene-deleted VTT recombinants (TTVAC7 and TTVC5).

Background: Multifocality is a distinctive feature of papillary thyroid carcinoma (PTC); however, the biological behavior of PTC and its optimal management strategy remain unclear. The aim of this study was to analyze the clinical features and prognostic differences of multifocal papillary carcinoma and to guide the precise treatment of multifocal papillary carcinoma.

Methods: The medical records of 1,139 patients with PTC who had undergone total or hemi-thyroidectomy between April and October 2013 at the Tianjin Medical University Cancer Institute and Hospital were reviewed.

Enhancing the passivation of heavy metals and increasing organic matter content during the composting of sewage sludge poses significant challenges for maximizing its utilization value. Results indicated that in the control, biochar, microbial agents and microbial agents-loaded biochar (BCLMA) groups, BCLMA addition led to a higher composting temperature, with increases of 17-62% in humic acid, 25-73% in germination index, and 30-35% in organic matter consumption. And the residual fraction of Cu, Zn, Cr and Cd were increased by 30%, 12%, 22% and 17%, respectively.

Antigen uptake, processing, and presentation are crucial for the immune responses of protein-based vaccines. Herein, we introduced a reversible chemical cross-linking strategy to engineer protein antigens, which can be tracelessly removed upon antigen-presenting cell (APC) uptake and cellular reduction. The chemically cross-linked antigen proteins presented significantly enhanced uptake and epitope presentation by APC.

The growth curve is a vital instrument for assessing and forecasting weight and developmental shifts in livestock and poultry, which reflects the changes of bodyweight traits with time and plays a key role in guiding breeding and production approaches. This study performed a genome-wide association study (GWAS) for growth curve parameters generated by nonlinear models which fit original weight-age records, to discover the SNPs and candidate genes correlated with growth traits. Data from 362 Chinese Wenshang Barred Chickens weighed at the age of 0, 2, 4, 6, 8, 10, 12, 14, 16, and 18 weeks were used to fit the Gompertz, Logistic, and von Bertalanffy growth models.

Food allergens are the key triggers of allergic diarrhea, causing damage to the immune-rich ileum. This weakens the mucosal barrier and tight junctions, increases intestinal permeability, and exacerbates allergen exposure, thereby worsening the condition. Sesamin, a natural lignan isolated from sesame seed, has shown potential in regulating immune responses, but its effects on intestinal health remain unclear.

The impact of the living environments on the intestinal microbiota of was studied by analyzing intestinal microbiota diversity, composition, and potential function among wild, domesticated, and cultured groups. The results showed that the fish living in the wild environment exhibited the highest alpha diversity of intestinal microbiota. Intestinal microbial communities in the three groups clustered by living environment, with domesticated and cultured groups showing higher similarity.

Article Synopsis
  • The study investigated the effects of sinomenine hydrochloride (SH) on colitis induced by DSS in mice, focusing on the Notch signaling pathway.
  • Mice were divided into four groups and assessed for disease activity, mucosal injury, and histopathological changes, revealing that SH significantly alleviated colitis symptoms and reduced inflammation markers.
  • Results indicated that SH treatment lowered the expression of key proteins in the Notch signaling pathway and reduced pro-inflammatory cytokines, suggesting that its therapeutic effect is linked to inhibiting Notch pathway overactivation.

Hepatic lipid metabolism dysfunction caused by cyanobacteria bloom-released microcystin-LR (MC-LR) contributes to the development of nonalcoholic fatty liver disease and nonalcoholic steatohepatitis (NASH), thereby severely impacting the health and safety of animals and humans. In this study, the effects and mechanisms of different environmental concentrations of MC-LR (0, 0.1, 1, and 10 μg/L) on fatty liver metabolic disease in zebrafish were investigated using in vivo, in vitro, and in silico models.

Poly(vinylidene fluoride) (PVDF) membranes with highly hydrophilic and antifouling properties are desirable for oily wastewater treatment. Herein, we report (1) a strategy of bulk modification of PVDF by integration of PVDF and a particle-based double-network (PDN) hydrogel, poly-2-acrylamido-2-methylpropanesulfonate/polyacrylamide (PAMPS/PAAm), via a strong PDN and PVDF interpenetrating polymer network (PDN-PVDF IPN) to obtain a PVDF/PDN solution and (2) the subsequent casting of it into a microfiltration membrane via spray-assisted non-solvent-induced phase separation (SANIPS). The IPN structure modulates the surface segregation behavior of the highly hydrophilic and robust PDN hydrogel in the process of SANIPS, endowing the resulting PVDF/PDN membrane with excellent bulk mechanical properties and much enhanced wettability and thereby high oil/water emulsion separation efficiency and antifouling performance.
