Efficacy of ceftazidime-avibactam with or without polymyxin for carbapenem-resistant infections after initial treatment with polymyxin.

Although polymyxins are a suboptimal option for difficult-to-treat resistant infections, they are still preferred as the first-line treatment, especially in low- and middle-income countries. This study assesses the efficacy of ceftazidime-avibactam (CAZ-AVI) following polymyxin B failure in patients with carbapenem-resistant (CRKP) infections. We retrospectively reviewed cases of infections caused by CRKP in adults who received CAZ-AVI as salvage therapy.

Identification and Validation of Telomere-Related Gene Signature in Intervertebral Disc Degeneration.

This study investigates the role of telomere-related differentially expressed genes (TRDEGs) in intervertebral disc degeneration (IVDD) through comprehensive bioinformatics analyses. Data were sourced from the Gene Expression Omnibus (GEO) with datasets GSE245147 and GSE124272 used for initial identification and validation, respectively. The GSE245147 dataset comprised transcriptional profiles from nucleus pulposus cells of both degenerated and non-degenerated human nucleus pulposus (NP) tissues.

Development and validation of an interpretable machine learning model for predicting the risk of distant metastasis in papillary thyroid cancer: a multicenter study.

Method: This meta-analysis searched three electronic databases (PubMed, Embase, Cochrane library), including 17 randomized and non-randomized controlled studies published since 2000-2023 that compared the effectiveness and safety of anterior and posterior surgical approaches for the treatment of ossification of the posterior longitudinal ligament.

Molecular mechanisms of MAZ targeting up-regulation of NDUFS3 expression to promote malignant progression in melanoma.

Myc-associated Zinc-finger Protein (MAZ) has been implicated in the malignant progression of various tumors. However, its expression and functional relationship of MAZ in melanoma have not been previously investigated. This study confirms elevated expression of MAZ in melanoma, correlating with poor patient prognosis.

TNFAIP2 promotes HIF1α transcription and breast cancer angiogenesis by activating the Rac1-ERK-AP1 signaling axis.

Angiogenesis is well known to play a critical role in breast cancer. We previously reported that TNFAIP2 activates Rac1 to promote triple-negative breast cancer (TNBC) cell proliferation, migration, and chemoresistance. However, the potential contribution of TNFAIP2 to tumor angiogenesis remains unknown.

A comprehensive genome-based analysis identifies the anti-cancerous role of the anoikis-related gene ADH1A in modulating the pathogenesis of breast cancer.

Breast cancer (BC), a widespread and lethal neoplasm, is irrespective of the subtype of BC. Metastasis remains a crucial determinant for unfavorable outcome. The identification of novel diagnostic markers is instrumental in optimizing the treatment regime for BC.

From dysfunction to healing: advances in mitochondrial therapy for Osteoarthritis.

Osteoarthritis (OA) is a chronic degenerative joint condition characterised by cartilage deterioration and changes in bone morphology, resulting in pain and impaired joint mobility. Investigation into the pathophysiological mechanisms underlying OA has highlighted the significance of mitochondrial dysfunction in its progression. Mitochondria, which are cellular organelles, play a crucial role in regulating energy metabolism, generating reactive oxygen species, and facilitating essential biological processes including apoptosis.

Multimodal neuroimaging-based prediction of Parkinson's disease with mild cognitive impairment using machine learning technique.

This study aimed to identify potential markers that can predict Parkinson's disease with mild cognitive impairment (PDMCI). We retrospectively collected general demographic data, clinically relevant scales, plasma samples, and neuroimaging data (T1-weighted magnetic resonance imaging (MRI) data as well as resting-state functional MRI [Rs-fMRI] data) from 173 individuals. Subsequently, based on the aforementioned multimodal indices, a support vector machine was employed to investigate the machine learning (ML) classification of PD patients with normal cognition (PDNC) and PDMCI.

Characterizing adipocytokine-related signatures for prognosis prediction in prostate cancer.

Background: Prostate cancer (PCa) is a prevalent malignant tumor in males, with a significant incidence of biochemical recurrence (BCR) despite advancements in treatment. Adipose tissue surrounding the prostate, known as periprostatic adipose tissue (PPAT), contributes to PCa invasion through adipocytokine production. However, the relationship between adipocytokine-related genes and PCa prognosis remains understudied.

The Mechanism of TRIM21 Inhibiting the Invasion and Migration of ccRCC by Stabilizing ASS1.

Clear cell renal cell carcinoma (ccRCC) is characterized by its aggressive invasion and metastasis, presenting significant clinical challenges. Gaining insights into the molecular mechanisms underlying its progression is crucial for the development of effective therapeutic strategies. Addressing a critical knowledge gap in understanding ccRCC tumorigenesis, this study aims to elucidate the expression patterns of TRIM21 in ccRCC, unravel its impact on ccRCC patient prognosis, and investigate the regulatory role of TRIM21 in ASS1 expression and urea cycle dysregulation within the context of ccRCC.

Single-cell transcriptome unveils unique transcriptomic signatures of human organ-specific endothelial cells.

The heterogeneity of endothelial cells (ECs) across human tissues remains incompletely inventoried. We constructed an atlas of > 210,000 ECs derived from 38 regions across 24 human tissues. Our analysis reveals significant differences in transcriptome, phenotype, metabolism and transcriptional regulation among ECs from various tissues.

Trem2/Tyrobp Signaling Protects Against Aortic Dissection and Rupture by Inhibiting Macrophage Activation in Mice.

Background: The development of aortic dissection (AD) is closely associated with inflammation. The Trem2 (triggering receptor expressed on myeloid cells 2)/Tyrobp (TYRO protein tyrosine kinase-binding protein) signaling pathway critically regulates innate immunity and has emerged as an important target in cardiovascular diseases; however, its role in AD remains unclear.

Methods: Transcriptome data from human and mouse ADs were used to perform differentially expressed gene-based protein-protein interaction network analyses.

[Strategies for applying noninvasive brain stimulation techniques to treat psychiatric disorders].

With the continuous development of science and technology, medical science, and bioengineering technology, various neuromodulation techniques, such as electrical, magnetic, acoustic, and optical modalities, are rapidly emerging in the therapeutic regime of psychiatric disorders. How to choose the appropriate noninvasive brain stimulation techniques for different psychiatric disorders and their clinical features is becoming a practical dilemma in clinical setting. In this paper, by describing the complex pathogenesis of psychiatric disorders and the limitations of existing therapeutic approaches on psychiatric disorders, combining with the characteristics of different neuromodulation techniques, we propose a new strategy of combined noninvasive brain stimulation to intervene in psychiatric disorders: high-intensity stimulation modulating the whole brain without inducing epilepsy should be as the basic treatment of psychiatric disorders, applying low-intensity stimulation with the advantage of specific targets/brain regions to modulate the residual symptoms or/and single symptom, and for refractory and acute psychiatric disorders, ECT/MECT is preferred for rapid symptom control; different noninvasive brain stimulation techniques can be combined with pharmacological and psychotherapeutic treatments, which will provide a new idea for the future development of this field.

Bone marrow mesenchymal stem cells overexpressing stromal cell- derived factor 1 aid in bone formation in osteoporotic mice.

Background: Osteoporosis is characterized by low systemic bone mineral content and destruction of bone microarchitecture. Promoting bone regeneration and reversing its loss by infusion of exogenous bone marrow mesenchymal stem cells (BMSCs) is a potentially effective treatment for osteoporosis. However, their limited migration to target organs reduces the therapeutic effect of the cells.
