Branch retinal artery occlusion in a patient with COVID-19 infection: A case report.

We report here, a case of branch retinal artery occlusion (BRAO) in the left eye of a 76-year-old man that involved three arteries which was considered to be related to a COVID-19 infection due to high levels of blood cytokines and coagulation factors. Although the patient had hypertension and atherosclerosis, his hypertension had been well controlled for the past five years by regular antihypertensive medication. Twenty-five days after starting treatment with anti-inflammatory, anticoagulant and conservative therapy, the patient's biomarkers of inflammation and coagulation returned to normal and his vision improved.

Associations between dietary iron intake from different sources and non-alcoholic fatty liver disease in adults.

Microglia lactylation in relation to central nervous system diseases.

The development of neurodegenerative diseases is closely related to the disruption of central nervous system homeostasis. Microglia, as innate immune cells, play important roles in the maintenance of central nervous system homeostasis, injury response, and neurodegenerative diseases. Lactate has been considered a metabolic waste product, but recent studies are revealing ever more of the physiological functions of lactate.

Columbianadin suppresses glioblastoma progression by inhibiting the PI3K-Akt signaling pathway.

Glioblastoma (GBM) is the most common malignant glioma among brain tumors with low survival rate and high recurrence rate. Columbianadin (CBN) has pharmacological properties such as anti-inflammatory, analgesic, thrombogenesis-inhibiting and anti-tumor effects. However, it remains unknown that the effect of CBN on GBM cells and its underlying molecular mechanisms.

Tenacissoside H repressed the progression of glioblastoma by inhibiting the PI3K/Akt/mTOR signaling pathway.

This study aimed to evaluate the clinical value of serum glutathione peroxidase 4 in nontraumatic osteonecrosis of the femoral head. This retrospective study analyzed serum glutathione peroxidase 4 levels and clinical data of 80 patients with nontraumatic osteonecrosis of the femoral head and 80 healthy controls between August 2021 and May 2022.

Dual targeting agent Thiotert inhibits the progression of glioblastoma by inducing ER stress-dependent autophagy.

Glioblastoma (GBM) is the most aggressive and lethal type of tumor in the central nervous system, characterized by a high incidence and poor prognosis. Thiotert, as a novel dual targeting agent, has potential inhibitory effects on various tumors. Here, we found that Thiotert effectively inhibited the proliferation of GBM cells by inducing G2/M cell cycle arrest and suppressed the migratory ability in vitro.

[Clinical characteristics and prognosis in 12 children with SARS-CoV-2 Omicron variant infection-associated acute necrotizing encephalopathy].

Objectives: To study the clinical characteristics and prognosis of SARS-CoV-2 Omicron variant infection-associated acute necrotizing encephalopathy (ANE) in children

Methods: A retrospective analysis was conducted on the medical data of 12 children with SARS-CoV-2 Omicron variant infection-associated ANE who were admitted to the Pediatric Intensive Care Unit, Qingdao Women and Children's Hospital from December 18 to 29, 2022. The children were divided into two groups based on outcomes: death group (7 cases) and survival group (5 cases). The clinical manifestations and auxiliary examination results were compared between the two groups.

Temporal artery biopsy for suspected giant cell arteritis: A mini review.

Giant cell arteritis (GCA) is a granulomatous inflammation involving medium and large vessels that can lead to serious clinical manifestations associated with tissue ischemia. Temporal artery biopsy (TAB) is currently the gold standard method for the diagnosis of GCA, with a specificity of 100% and a sensitivity of 77%. However, the false-negative rate for TAB ranges from 9% to 61%.

Identification and detection of microplastic particles in marine environment by using improved faster R-CNN model.

Microplastics refer to plastic particles measuring less than 5 mm, which has led to serious environmental problem and the detection of these tiny particles is crucial for understanding the corresponding distribution and impact on the marine environment. In this paper, an improved faster region-based convolutional neural network (R-CNN) model was developed for the identification and detection of microplastic particles. In the proposed model, the residual network-50 (ResNet-50) is employed as the backbone with the replacement of the traditional one to enhance the feature extraction capability and the feature pyramid networks (FPN) module is introduced together for solving the multi-scale target detection.
