Advances in cardiac ultrasound speckle tracking technology for assessing left ventricular systolic function after adjuvant radiotherapy following breast-conserving surgery for breast cancer.

Breast-conserving surgery is a widely used treatment for breast cancer, often followed by adjuvant therapy such as adjuvant paclitaxel and trastuzumab (APT). While APT effectively reduces local recurrence and distant metastasis, it may also impair left ventricular systolic function. Speckle tracking imaging (STI) is a noninvasive ultrasound technique that quantitatively evaluates overall cardiac function.

TLR3 polymorphisms are associated with the severity of hand, foot, and mouth disease caused by enterovirus A71 in a Chinese children population.

Hand, foot, and mouth disease (HFMD) caused by enterovirus A71 (EV-A71) is a contagious viral disease, and toll-like receptors (TLRs) play essential roles in resisting the pathogen. The aim of this study was to assess the potential relationship between several TLRs polymorphisms and the HFMD severity in a Chinese children population. A total of 328 Chinese children with HFMD were included in the present study.

Geranylgeranyl Transferase-I Knockout Inhibits Oxidative Injury of Vascular Smooth Muscle Cells and Attenuates Diabetes-Accelerated Atherosclerosis.

The proliferation of vascular smooth muscle cells (VSMCs) induced by oxidative injury is one of the main features in diabetes-accelerated atherosclerosis. Geranylgeranyl transferase-I (GGTase-I) is an essential enzyme mediating posttranslational modification, especially the geranylgeranylation of small GTPase, Rac1. Our previous studies found that GGTase-I played an important role in diabetes-accelerated atherosclerosis.

The perplexity of catheter-directed thrombolysis for deep venous thrombosis: the approaches play an important role.

The recent adjunctive catheter-directed thrombolysis (ATTRACT) trial rose a controversy about the treatment effect of catheter-directed thrombolysis (CDT) in deep venous thrombosis (DVT). In fact, most studies including the ATTRACT trial did not perform subgroup analysis of catheterization approaches. Different approaches would confound the conclusions.

MicroRNA‑125a‑mediated regulation of the mevalonate signaling pathway contributes to high glucose‑induced proliferation and migration of vascular smooth muscle cells.

Hyperglycemia contributes to the excessive proliferation and migration of vascular smooth muscle cells (VSMC), which are closely associated with atherosclerosis. MicroRNAs (miRNAs/miRs) constitute a novel class of gene regulators, which have important roles in various pathological conditions. The aim of the present study was to identify miRNAs involved in the high glucose (HG)‑induced VSMC phenotype switch, and to investigate the underlying mechanism.

Effect of Moringa oleifera supplementation on productive performance, colostrum composition and serum biochemical indexes of sow.

Moringa oleifera has been considered as a potential functional feed or food, since it contains multiple components beneficial to animal and human. However, little is known about the effects of Moringa oleifera supplementation on productive performances in sows. In the current study, the results showed that dietary Moringa oleifera significantly decreased the farrowing length and the number of stillborn (p < .

Modified unilateral video-assisted thoracoscopic extended thymectomy for myasthenia gravis using 5-mm incisions: A case report.

Rationale: Myasthenia gravis (MG) is the most common cause of acquired neuromuscular junction disorder. Thymectomy has been established as an effective therapy for MG, as it attenuates the natural course of the disease and may result in complete remission.

Patient Concerns: We report the case of a 22-year-old female with a 6-year history of MG presented with bilateral ptosis, diplopia, and intermittent dysphagia.

Relationship between CaSRs and LPS-injured cardiomyocytes.

Objective: Calcium-sensing receptors (CaSRs) regulate systemic calcium homeostasis. Intracellular calcium concentration changes are initiating factors of endoplasmic reticulum stress and cell autophagy. Recent research has revealed that CaSRs play an important role in myocardial ischemia/reperfusion injury and other cardiovascular diseases.

MiRNA-mRNA crosstalk in laryngeal squamous cell carcinoma based on the TCGA database.

Background: The functional characterization of non-coding microRNAs (miRNAs) has been shown to be associated with the pathophysiology of the disease, but it is still a challenging task to elucidate the pathogenesis of microRNAs and disease. In addition, the understanding of the role of miRNAs in the development of LSCC still needs further exploration.

Materials And Methods: In this study, to identify miRNAs that play a key role in LSCC, we analyzed miRNA and mRNA sequence data from 162 LSCC samples from the TCGA database, and screened specific miRNAs and mRNAs by differential gene expression analysis.

Completely thoracoscopic right upper lobectomy and mediastinal lymph node dissection.

Video-assisted thoracoscopic surgery (VATS) has been constantly used in the diagnosis and treatment of intrathoracic disease. The focus of VATS is primarily concerned with the completeness of mediastinal lymph node dissection for lung cancer and the safety of surgery. Here we discuss the feasibility of VATS right upper lobectomy and systematic lymph node dissection, for a 60-year-old woman who was admitted for tumor of the right upper lobe, and describe this treatment method and the major indications.

The effects of endovenous radiofrequency ablation on coagulation and the vein wall in an experimental canine model.

Endovenous radiofrequency ablation (RFA) has been introduced as a less invasive alternative to traditional surgery for varicose veins, but vein thrombosis after RFA remains a concern. This study investigated the influence of endovenous RFA on coagulable states of canine blood, and changes in the vein wall and lumen. Eight canines underwent RFA of the iliac-femoral vein.
