STAC3 as a poor prognostic biomarker in renal clear cell carcinoma: relationship with immune infiltration.

Calcium ions (Ca) are crucial in tumorigenesis and progression, with their elevated levels indicating a negative prognosis in Kidney Renal Clear Cell Carcinoma (KIRC). The influence of genes regulating calcium ions on the survival outcomes of KIRC patients and their interaction with the tumor's immune microenvironment is yet to be fully understood. This study analyzed gene expression data from KIRC tumor and adjacent non-tumor tissues using the TCGA-KIRC dataset to pinpoint genes that are differentially expressed in KIRC.

Comparative study of disease progression for heart failure with different etiologies via time-ordered network analysis.

Objectives: Heart failure (HF), the primary end-stage manifestation of multiple cardiovascular diseases, has become a global epidemic with high morbidity and mortality. However, the mechanisms underlying the pathogenesis of HF with different etiologies have yet to be fully elucidated.

Methods: In this study, we developed a novel method to determine the dysregulated lncRNA-mRNA regulation pairs (LMRPs) in the different causes that lead to HF.

TOP2A inhibition reverses drug resistance of hepatocellular carcinoma to regorafenib.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death attributed to high frequency of metastasis and multiple drug resistance. We aim to examine the underlying molecular mechanism and to seek potential strategies to reverse primary/acquired resistance to regorafenib. Topoisomerase IIα (TOP2A) is critical for tumorigenesis and carcinogenesis.

A rare presentation of lung squamous cell carcinoma metastasis to the distal phalanx of the little finger: a case report.

Sangerbox: A comprehensive, interaction-friendly clinical bioinformatics analysis platform.

In recent decades, with the continuous development of high-throughput sequencing technology, data volume in medical research has increased, at the same time, almost all clinical researchers have their own independent omics data, which provided a better condition for data mining and a deeper understanding of gene functions. However, for these large amounts of data, many common and cutting-edge effective bioinformatics research methods still cannot be widely used. This has encouraged the establishment of many analytical platforms, a portion of databases or platforms were designed to solve the special analysis needs of users, for instance, MG RAST, IMG/M, Qiita, BIGSdb, and TRAPR were developed for specific omics research, and some databases or servers provide solutions for special problems solutions.

LncRNA NR2F2-AS1 induces epithelial-mesenchymal transition of non-small cell lung cancer by modulating BVR/ATF-2 pathway via regulating miR-545-5p/c-Met axis.

Background: Proteasome activator γ (REG γ) expression was found to be upregulated and to play critical roles in several cancers. However, the effect of REG γ on osteosarcoma (OS) remains unclear. The objective of the present study was to explore the clinical significance of REG γ and its function in regulating the progression of OS.

Probiotics alleviate cognitive dysfunction associated with neuroinflammation in cardiac surgery.

Neuroinflammation plays a key role in the progression and pathogenesis of postoperative cognitive dysfunction, but it does not always occur in the local response to primary injury. In this study, we revealed that probiotics alleviate cognitive dysfunction associated with neuroinflammation in cardiac surgery. Rats were administered a probiotic or placebo once a day by gavage for 2 weeks until the day of surgery.

Pentoxifylline inhibits pulmonary inflammation induced by infrarenal aorticcross-clamping dependent of adenosine receptor A2A.

Infrarenal aortic cross-clamping (IAC) is commonly used during infrarenal vascular operations. Prolonged IAC causes ischemia-reperfusion injury to local tissues, resulting in the release of inflammatory cytokines and acute lung injury (ALI). Pentoxifylline (PTX) is a clinically used drug for chronic occlusive arterial diseases and exerts protective effects against ALI induced by various factors in experimental models.

Survey and coping strategies for job stress of new nurses in pharmacy intravenous admixture service: a pilot study.

A questionnaire survey referring to the revised stressor scale was carried out on 52 new nurses of PIAS in four hospitals in Harbin. The average stress score for all participants was 2.

Downregulation of SUMF2 gene in ovalbumin-induced rat model of allergic inflammation.

Sulfate-modifying factor 2 (SUMF2), a member of the formylglycine-generating enzyme family, was earlier found to play a role in the regulation of interleukin (IL)-13 expression and secretion in airway smooth muscle cells. IL-13 is a T helper 2 cytokine that plays important roles in the pathogenesis of asthma. However, there is little evidence of the potential role of SUMF2 in the cellular inflammatory responses in asthma.

Comparison of the efficacy of recombinant human brain natriuretic peptide with saline hydration in preventing contrast-induced nephropathy in patients undergoing coronary angiography with or without concomitant percutaneous coronary intervention.

The incidence of contrast-induced nephropathy has an increasing trend as a result of increased use of contrast media during coronary interventional procedures. Contrast-induced nephropathy is one of the major causes for hospital acquired renal failure after coronary interventional procedures. In this study, a total of 126 enrolled patients undergoing elective coronary angiography and/or percutaneous coronary intervention were randomly divided into two groups to investigate the efficacy of recombinant human brain natriuretic peptide in preventing contrast-induced nephropathy in patients undergoing elective coronary angiography and/or percutaneous coronary intervention.

RNA-seq analysis of glycosylation related gene expression in STZ-induced diabetic rat kidney inner medulla.

Unlabelled: The UT-A1 urea transporter is crucial to the kidney's ability to generate concentrated urine. Native UT-A1 from kidney inner medulla (IM) is a heavily glycosylated protein with two glycosylation forms of 97 and 117 kDa. In diabetes, UT-A1 protein abundance, particularly the 117 kD isoform, is significantly increased corresponding to an increased urea permeability in perfused IM collecting ducts, which plays an important role in preventing the osmotic diuresis caused by glucosuria.
