Heterologous expression of the M. abscessus CBASS system confers phage TM4 resistance in M. smegmatis.

Phage therapy for multidrug-resistant Mycobacterium abscessus is constrained by the narrow lytic spectrum of phages due to unknown antiphage mechanisms. Bacteria deploy various defense strategies to prevent phage infection, but few have been comprehensively characterized in mycobacteria. Mycobacteriophage TM4 successfully delivers DNA into M.

Mechanism of lncRNA WARS2-IT1 promoting angiogenesis of glioma through miR-299-3P/VEGFA axis and activating PI3K/AKT signaling pathway.

Unlabelled: Glioma is a common primary intracranial tumor with easy recurrence and poor prognosis. Emerging evidence has highlighted the involvement of LncRNA in glioma proliferation, invasion, migration and angiogenesis, but at present, there is no relevant research on LncRNA WARS2-IT1.

Comparative Evaluation of Resting and Hyperemic Angiography-Derived Index of Microcirculatory Resistance in Chronic Coronary Syndrome.

Background: Angiography-derived index of microcirculatory resistance (IMR) has emerged as a feasible alternative to wire-based IMR, due to the elimination of specialized wire and simplifying of the procedure. However, the differences in diagnostic accuracy between hyperemic and resting angiography with this technology remain underexplored.

Methods: This prospective, multicenter study was conducted to evaluate the feasibility and diagnostic accuracy of x-ray angiography-derived IMR (xaIMR) in patients with chronic coronary syndrome using wire-based functional indices as the reference.

To accurately analyze the geometry changesof the bone graft (BG) in the maxillary sinus (MS), it is essential to perform quantitative analysis. However, automated BG segmentation remains a major challenge due to the complex local appearance, including blurred boundaries, lesion interference, implant and artifact interference, and BG exceeding the MS.

Right Bundle Branch Block on ECG as a Predictor of Sudden Cardiac Arrest Due to Pulmonary Embolism.

BACKGROUND High-risk pulmonary embolism (PE) refers to a subset of massive PE that can lead to sudden cardiac arrest (SCA) or hemodynamic collapse. It is crucial to identify the clues that might precede high-risk PE in resuscitated SCA. The presence of right bundle branch block (RBBB) with a QR pattern in V1 on the electrocardiogram (ECG) has a high positive predictive value for diagnosing cardiac arrest caused by high-risk PE.

Delayed Diagnosis of Constrictive Pericarditis Resulting in Recurrent Heart Failure: A Case Report.

Constrictive pericarditis can lead to compromised diastolic ventricular filling due to pericardial inflammation and fibrosis. A diagnosis of constrictive pericarditis was established by identifying structural and hemodynamic features through echocardiography. We present a case of constrictive pericarditis, which manifested in the form of gradually worsening dyspnea and lower-extremity edema over a 7 years period.

Exploring blood transcriptomic signatures in patients with herpes zoster and postherpetic neuralgia.

Postherpetic neuralgia (PHN) is a common, severe, and hard-to-treat chronic pain condition in clinics. Although PHN is developed from herpes zoster (HZ), the developing mechanism is unknown. A previous study investigated blood metabolomic and proteomic profiling in patients with PHN and HZ.

HS-GC-IMS Analysis of Volatile Organic Compounds in Six Spicy Spices and Their Effects on Ulcerative Colitis.

The volatile organic compounds of six spices, including black pepper, dried ginger, cinnamon, fennel, clove, and zanthoxylum, were analyzed by gas chromatography-ion mobility spectrometry (HS-GC-IMS) combined with principal component analysis (PCA) and Euclidean distance. In further analyses, the effects of volatile oils in six spices on ulcerative colitis were assayed in a zebrafish model induced by 3-nitrobenzenesulfonic acid. A total of 120 kinds of volatile organic compounds were detected and 80 among them were identified, which included 10 common components and 3 to 24 characteristic components belonging to different spices.

A novel approach for large-scale characterization of residential cooking-generated PM with computer vision and low-cost sensors.

Cooking is one of the major sources of indoor particulate matter (PM), which poses significant health risks and is a severe health hazard. Current studies lack an economical and effective analytical framework for quantifying inhalable particles (PM) and fine particulate matter (PM) from residential cooking activities on a large scale under real-world scenarios. This study bridges this gap by employing computer vision (CV) technology and readily available sensors.
