Fatigue Life Prediction of CFRP-FBG Sensor-Reinforced RC Beams Enabled by LSTM-Based Deep Learning.

Amidst the escalating demand for high-precision structural health monitoring in large-scale engineering applications, carbon fiber-reinforced polymer fiber Bragg grating (CFRP-FBG) sensors have emerged as a pivotal technology for fatigue life evaluation, owing to their exceptional sensitivity and intrinsic immunity to electromagnetic interference. A time-series predictive architecture based on long short-term memory (LSTM) networks is developed in this work to facilitate intelligent fatigue life assessment of structures subjected to complex cyclic loading by capturing and modeling critical spectral characteristics of CFRP-FBG sensors, specifically the side-mode suppression ratio and main-lobe peak-to-valley ratio. To enhance model robustness and generalization, Principal Component Analysis (PCA) was employed to isolate the most salient spectral features, followed by data preprocessing via normalization and model optimization through the integration of the Adam optimizer and Dropout regularization strategy.

Preliminary study on the correlation between thyroid magnetic resonance parameters and radiation dose after radiotherapy for nasopharyngeal carcinoma.

Background: Hypothyroidism is a common sequela after radiotherapy for nasopharyngeal carcinoma (NPC). Magnetic resonance imaging (MRI) has gained prominence in thyroid imaging, leveraging its non-ionizing radiation, high spatial resolution, multiparameter and multidirectional imaging. Few previous studies have investigated the evaluation of radiation-induced thyroid injury by MRI.

Dapagliflozin improves diabetic kidney disease by inhibiting ferroptosis through β-hydroxybutyrate production.

Background: Diabetic kidney disease (DKD) is the leading cause of end-stage renal disease. Sodium-glucose cotransporter protein 2 inhibitors (SGLT2i) are antihyperglycemic agents that provide additional renal-protective effects in patients with DKD, independent of their glucose-lowering effects. However, the underlying mechanism remains unclear.

Metabolic Dysfunction in Idiopathic Intracranial Hypertension: Current Theories and Updates.

Idiopathic intracranial hypertension (IIH) is a disease characterized by increased intracranial pressure (ICP) without identifiable secondary causes. While the increased ICP is a critical diagnostic feature, the underlying pathophysiological mechanisms remain unclear. Previous theories have suggested cerebrospinal fluid (CSF) overproduction, impaired reabsorption, or circulatory obstruction as potential causes.

Association of serum Metrnl levels and high-density lipoprotein cholesterol in patients with type 2 diabetes mellitus: a cross-sectional study.

Purpose: Meteorin-like (Metrnl) is a novel adipokine which is highly expressed in adipose tissue and has a beneficial effect on glucose and lipid metabolism. High density lipoprotein cholesterol (HDL-C) is well recognized to be inversely associated with cardiovascular events. However, the relationship between serum Metrnl levels and HDL-C in the type 2 diabetes mellitus (T2DM) remains unclear.

Durability Properties of Steel Textiles and Bonding Properties at the Interface of Steel Textiles with Reinforced Mortar-Reinforced Concrete Systems.

Aging and deterioration of building structures have been persistent concerns in the field of engineering. To address these challenges while supporting modern green and sustainable development goals, this study introduces an innovative reinforcement system that employs steel textiles as the primary reinforcing material. The steel textiles were engineered by optimizing the compatibility between steel fibers and a hot melt adhesive (HMA).

Progress and recognition of idiopathic intracranial hypertension: A narrative review.

Background: Idiopathic intracranial hypertension (IIH) mainly affects obese young women, causing elevated intracranial pressure, headaches, and papilledema, risking vision loss and severe headaches. Despite weight loss as the primary treatment, the underlying mechanisms remain unclear. Recent research explores novel therapeutic targets.

Correlation between cerebral neurotransmitters levels by proton magnetic resonance spectroscopy and HbA1c in patients with type 2 diabetes.

Background: Cognitive dysfunction is the main manifestation of central neuropathy. Although cognitive impairments tend to be overlooked in patients with diabetes mellitus (DM), there is a growing body of evidence linking DM to cognitive dysfunction. Hyperglycemia is closely related to neurological abnormalities, while often disregarded in clinical practice.

Epidemiology, pathogenesis, and management of Coronavirus disease 2019-associated stroke.

The Coronavirus disease 2019 (COVID-19) epidemic has triggered a huge impact on healthcare, socioeconomics, and other aspects of the world over the past three years. An increasing number of studies have identified a complex relationship between COVID-19 and stroke, although active measures are being implemented to prevent disease transmission. Severe COVID-19 may be associated with an increased risk of stroke and increase the rates of disability and mortality, posing a serious challenge to acute stroke diagnosis, treatment, and care.

Cortical vein involvement and its influence in a cohort of adolescents with cerebral venous thrombosis.

Background And Purpose: Cortical vein thrombosis (CVT) is a rare form of cerebral venous sinus thrombosis (CVST) in adolescent patients that has received little attention. We aimed to analyze the clinical and radiological features of adolescents with CVST and investigate the effects of CVT involvement.

Methods: Patients aged ≥ 10 to ≤ 18 years and diagnosed with CVST were identified at Xuanwu Hospital, Capital Medical University between January 2015 and August 2022 and divided into two groups according to the presence or absence of cortical vein involvement.

Monitoring the Effects of Hemicellulase on the Different Proofing Stages of Wheat Aleurone-Rich Bread Dough and Bread Quality.

This study investigated the effects of a hemicellulase dosage (20, 40, and 60 mg kg of flour) on the bread quality and rheological properties of wheat aleurone-rich flour. The results showed that hemicellulase could soften dough and improve extensibility. At the optimum hemicellulase dosage (40 mg kg of flour), the bread specific volume increased by 40.

HuR promotes breast cancer cell proliferation and survival via binding to CDK3 mRNA.

HuR, a ubiquitously expressed RNA-binding protein, stabilizes mRNA and regulates its translation. HuR expression was increased at all stages of breast cancer and correlated with poor clinical outcome. However, the detailed mechanisms remain unclear.
