Exploring lipidomic profiles and their correlation with hormone receptor and HER2 status in breast cancer.

Dysregulated lipid metabolism promotes the progression of various cancer types, including breast cancer. The present study aimed to explore the lipidomic profiles of patients with breast cancer, providing insights into the correlation between lipid compositions and tumor subtypes characterized by hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) status. Briefly, 30 patients with breast cancer were categorized into four groups based on their HR and HER2 status: HR+ no HER2 expression (HER2-0), HR+ HER2-low; HR+ HER2-positive (pos) and HR- HER2-pos.

DCX knockout ferret reveals a neurogenic mechanism in cortical development.

Lissencephaly is a rare brain malformation for which our understanding remains limited due to the absence of suitable animal models that accurately represent human phenotypes. Here, we establish doublecortin (DCX) knockout ferrets as a model that faithfully replicates key features of the disorder. We reveal the critical roles of DCX in neural progenitor cell proliferation and radial glial fiber extension, processes essential for normal cortical development.

Single-cell epigenomics and spatiotemporal transcriptomics reveal human cerebellar development.

Human cerebellar development is orchestrated by molecular regulatory networks to achieve cytoarchitecture and coordinate motor and cognitive functions. Here, we combined single-cell transcriptomics, spatial transcriptomics and single cell chromatin accessibility states to systematically depict an integrative spatiotemporal landscape of human fetal cerebellar development. We revealed that combinations of transcription factors and cis-regulatory elements (CREs) play roles in governing progenitor differentiation and cell fate determination along trajectories in a hierarchical manner, providing a gene expression regulatory map of cell fate and spatial information for these cells.

Cuproptosis: A novel therapeutic target for overcoming cancer drug resistance.

Cuproptosis is a newly identified form of cell death driven by copper. Recently, the role of copper and copper triggered cell death in the pathogenesis of cancers have attracted attentions. Cuproptosis has garnered enormous interest in cancer research communities because of its great potential for cancer therapy.

FBXO38 mediates FGL1 ubiquitination and degradation to enhance cancer immunity and suppress inflammation.

Upregulation of FGL1 helps tumors escape from immune surveillance, and therapeutic antibodies targeting FGL1 have potential as another immune checkpoint inhibitor. However, the underlying mechanism of high FGL1 protein level in cancers is not well defined. Here, we report that FBXO38 interacts with and ubiquitylates FGL1 to negatively regulate its stability and to mediate cancer immune response.

Squamous cell carcinoma of the cystic duct: A case report and literature review.

Rationale: Pure squamous cell carcinoma (SCC) of the gallbladder is a rare malignant biliary tract tumor predominantly found in the body and neck of the gallbladder. However, its occurrence in the cystic duct is even rarer. Given its rarity, no established guidelines or consensus currently exist regarding the treatment of pure SCC of the gallbladder.

Audit to assess the quality of 916 prosthetic prescriptions of removable partial dentures.

Objectives: The objectives of this study were to assess the quality of prosthetic prescriptions of removable partial dentures (RPDs) and to analyze the current situation of the communication and information delivery between clinicians and technicians.

Methods: All RPD prosthetic prescriptions received by a major dental laboratory in 4 weeks were involved in a quality audit, and the prescriptions were divided into three groups in accordance with the grades of clients. The filling of prosthetic prescriptions was recorded.

Digital technology for fluid resin injection to close anterior diastema after orthodontic treatment.

Anterior diastema and tooth defects are common clinical issues in restorative dentistry and are often restored by veneers or crowns based on the results of digital smile design and wax-up. Traditional direct resin restoration for closing a diastema is relatively minimally invasive but is time consuming and laborious, and shape control depends on experience. Digital technology can be used to design and transfer the shape of aesthetic restoration more accurately and quickly; thus, it could close anterior diastema and restore defects easily.

Kidney ion handling genes and their interaction in blood pressure control.

Hypertension affects 30% of adults and is the leading risk factor for cardiovascular disease. Kidney sodium reabsorption plays a vital role in the initial stage and development of essential hypertension. It has been extensively reported that the variants of kidney ion handling genes are associated to blood pressure, and clinical features of hypertension.

A modified kidney-sparing portal vein arterialization model of heterotopic auxiliary liver transplantation increases liver IL-6, TNF-α, and HGF levels and enhances liver regeneration: an animal model.

Background And Aim: The success of partial donor liver transplantation is affected by the implantation site of the donor liver and the vascular reconstruction approach. We investigated the effects of different donor liver implantation sites and vascular reconstruction approaches on liver regeneration using a rat kidney-sparing heterotopic auxiliary liver transplantation model, with portal vein arterialization (PVA).

Methods: Sixty male Sprague-Dawley rats underwent end-to-end anastomosis of the donor liver portal vein and the right renal artery stent (control group), or end-to-side anastomosis of the donor liver portal vein and the left common iliac artery (experimental group).

A digital workflow for layering composite resin restorations by using 3-dimensionally printed templates to replicate the contralateral tooth accurately and rapidly.

This article described a digital workflow for layering composite resin restorations by using a digital software program and 3-dimensionally printed templates. To mimic the appearance of the natural tooth, the computer-aided design was used to copy the shape of the contralateral tooth. Three-dimensionally printed templates to replicate the contralateral tooth accurately and rapidly can help dentists build different layers of dentin and enamel composite resin, achieving layered esthetic outcomes.

Mouse and human share conserved transcriptional programs for interneuron development.

Genetic variation confers susceptibility to neurodevelopmental disorders by affecting the development of specific cell types. Changes in cortical and striatal γ-aminobutyric acid–expressing (GABAergic) neurons are common in autism and schizophrenia. In this study, we used single-cell RNA sequencing to characterize the emergence of cell diversity in the human ganglionic eminences, the transitory structures of the human fetal brain where striatal and cortical GABAergic neurons are generated.

Successful totally laparoscopic right trihepatectomy following conversion therapy for hepatocellular carcinoma: A case report.

Background: About 20%-30% of newly diagnosed hepatocellular carcinoma (HCC) patients are surgically feasible due to a variety of reasons. Active conversion therapy may provide opportunities of surgery for these patients. Nevertheless, the choice of surgical procedure is controversial after successful conversion therapy.

Transcriptomic encoding of sensorimotor transformation in the midbrain.

Sensorimotor transformation, a process that converts sensory stimuli into motor actions, is critical for the brain to initiate behaviors. Although the circuitry involved in sensorimotor transformation has been well delineated, the molecular logic behind this process remains poorly understood. Here, we performed high-throughput and circuit-specific single-cell transcriptomic analyses of neurons in the superior colliculus (SC), a midbrain structure implicated in early sensorimotor transformation.
