Dental bur detection system based on asymmetric double convolution and adaptive feature fusion.
Sci Rep
December 2024
School of Mechanical Engineering, Shaanxi University of Technology, Hanzhong, 723001, China.
This study aims to improve the detection of dental burs, which are often undetected due to their minuscule size, slender profile, and substantial manufacturing output. The present study introduces You Only Look Once-Dental bur (YOLO-DB), an innovative deep learning-driven methodology for the accurate detection and counting of dental burs. A Lightweight Asymmetric Dual Convolution module (LADC) was devised to diminish the detrimental effects of extraneous features on the model's precision, thereby enhancing the feature extraction network.

Purpose: An analytical method was developed for determining ropivacaine and its main metabolite, 3-hydroxyropivacaine in biomedical samples using gas chromatography-tandem mass spectrometry (GC-MS/MS). Then, this established method was applied to investigate the distribution of ropivacaine and its metabolite in human fluids and solid tissues obtained from an authentic case ropivacaine involved.
Methods: The fluid sample was added acetonitrile, and solid tissue was homogenized using a freezer mill and then added into acetonitrile.
Magnification in preclinical procedures: effect on muscle activity and angular deviations of the neck and trunk.

Department of Social Dentistry, School of Dentistry of Araraquara, Universidade Estadual Paulista, Araraquara, São Paulo, Brazil.
Objectives: This study aimed to assess the effects of different magnification systems on the angular deviations of the neck and trunk and the muscle activities of the upper back and neck during preclinical cavity preparation.
Methods: This was an experimental laboratory study, with the angular deviations from the neutral positions of the neck and trunk and the activities of the bilateral upper back (the descending and ascending trapezius) and neck (sternocleidomastoid) muscles as the dependent variables. The independent variables were the different magnification systems used (Simple, Galilean, and Keplerian loupes, with direct vision as the control) and prepared teeth (teeth 16, 26, 36, and 46).
Gut Microbiota: Potential Therapeutic Target for Sickle Cell Disease Pain and Complications.
Anemia
March 2024
Department of Agricultural Biotechnology, National Biotechnology Development Agency, Abuja, Nigeria.
Aim: Sickle cell disease has witnessed a 41.4% surge from 2000 to 2021, significantly affecting morbidity and mortality rates, particularly in children from regions with elevated under-5 mortality rates. Gut microbiota dysbiosis is increasingly recognised in SCD, exacerbating complications, particularly chronic pain, marked by significant alterations of proinflammatory bacteria abundance.

Article Synopsis
- The study investigates the effectiveness of Cerabone® biomaterial and Photobiomodulation (PBM) for enhancing bone growth in the maxillary sinus.
- Eight participants underwent surgery where their maxillary sinuses were filled with Cerabone®, with some receiving additional PBM treatment to assess its effects on bone formation.
- Results showed both groups had new bone formation, but the PBM group exhibited significantly more advanced bone maturation and higher levels of osteocalcin, indicating improved healing compared to the control group.*
