Article Synopsis
  • Multivariate time series anomaly detection is crucial in fields like IT, finance, and medicine, but existing models struggle with capturing complex, multi-scale patterns, leading to lower accuracy in detecting anomalies.
  • To tackle this challenge, the MFAM-AD model combines convolutional neural networks (CNNs) and bi-directional long short-term memory (Bi-LSTM) to improve detection by integrating temporal dependencies and multi-scale features effectively.
  • Experimental results show that MFAM-AD outperforms or closely matches state-of-the-art models, achieving higher F1 scores on several datasets, which confirms its effectiveness for real-world anomaly detection applications.

Wheat is the most widely grown crop in the world, and its yield is closely related to global food security. The number of ears is important for wheat breeding and yield estimation. Therefore, automated wheat ear counting techniques are essential for breeding high-yield varieties and increasing grain yield.

Plant disease, a huge burden, can cause yield loss of up to 100% and thus reduce food security. Actually, smart diagnosing diseases with plant phenomics is crucial for recovering the most yield loss, which usually requires sufficient image information. Hence, phenomics is being pursued as an independent discipline to enable the development of high-throughput phenotyping for plant disease.

To evaluate the correlation of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV) with parameters related to gout activity. The general data of the patients and healthy controls (HCs), including complete blood count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum uric acid (SUA), and the presence of tophi were retrospectively analyzed. NLR, MPV, and PLR were calculated in patients with intercritical gout and gout flares.

Background: Chronic obstructive pulmonary disease (COPD) is a disease that causes obstructed airways and abnormal inflammatory responses in the lungs. Early growth response 3 (EGR3) has been revealed to play a vital role in the regulation of the inflammatory response in certain diseases. We aimed to explore the role of EGR3 and its upstream mechanism in COPD.

The aberrant expression of microRNA is an important regulator in the tumorigenesis of non-small cell lung cancer. In this study, we found that miR-499a-5p was notably downregulated in non-small cell lung cancer tissues and cell lines. Decreased miR-499a-5p expression was associated with larger tumor size and higher TNM stage.

Drug resistance is an obstacle in the chemotherapeutic treatment of lung cancers. In the present study, the effects of high-mobility group box 1 (HMGB1) protein in chemotherapeutic resistance and the relationships between HMGB1 and chemotherapy drug-induced cell apoptosis or necrosis were clarified. We used cisplatin-sensitive A549 cells and cisplatin-resistant A549/DDP cells as cell models with IC50 of 11.

Objectives: To develop an intermittent hypoxia/reoxygenation (IH/ROX) rabbit carotid artery model and then investigate the inflammation status of rabbit carotid artery endothelium after IH exposure and its relationship with leptin.

Materials And Methods: After anesthetization, rabbit's right common carotid artery was cleared of surrounding tissue with anatomic microscope, cannulated to its distal part and the proximal part was ligated. Preparations were challenged by changing the PO(2) of the gas mixture equilibrating the perfusate.

Objective: To explore the inflammatory reactions, endothelin level and carotid sinus nerve (CSN) afferent activity of carotid body (CB) after intermittent hypoxia/reoxygenation (IH/ROX) exposure of various frequencies in rabbits.

Methods: Forty-nine male adult New Zealand white rabbits (2.5-3.
