It is generally accepted that the development of cancer in oral mucosa preceded by an identifiable non-invasive precursor lesion. The aim this follow-up study was to estimate rate and time transformation a group patients from southern Taiwan with potentially malignant epithelial lesions.The defined as duration between onset initial diagnosis occurrence confirmed cancer. A total 1458 histological diagnoses various pre-malignant lesions were followed up 1991 2001. average age at 47.5 years....
Erythrocyte aldehyde dehydrogenase activity was determined in 44 chronic alcoholic patients within 18–36 hr after discontinuation of alcohol intake and 20 nonalcoholic controls. The enzyme decreased to 4.98 ± 0.52 mlU/mg protein the alcoholics as compared with a value 8.25 1.29 controls (p < 0.05). level did not correlate significantly daily quantity consumption or degree liver injury reflected elevations serum aspartate aminotransferase.

Abstract Objective To evaluate the effects of changes in prosthetic cup inclination on impingement-free hip abduction, adduction, and internal external rotation after simulated total replacement dogs. Methods For 6 dogs, CT scans region were used to prepare 3-D surface models cementless replacement. each dog, 15 with ranging from −35° 35° 5° increments prepared using computer-aided design software. implant position, motion was evaluated a custom-built computer program for flexion/extension...
ABSTRACT Lugol chromoendoscopy is widely used for screening esophageal squamous cell neoplasms (ESCNs) and evaluating dissection margins during endoscopic submucosal (ESD). However, morphological variations may arise following treatment synchronous cancers. This study aimed to assess the impact of chemotherapy on findings both ESD. From August 2009 March 2024, ESCN patients undergoing ESD were enrolled. analyzed based four criteria: iodine staining, lesion size, margin assessment, pink‐color...
Intra‐oral lipoma is a well‐known entity, but lipomatous tumors including salivary gland tissue containing clustered or peripherally located ducts and acinar cells are uncommon. They newly recognized entity of lipoma, designated sialolipoma. We describe case sialolipoma arising in the floor mouth presenting with apparently normal tissue, as demonstrated by both histologic immunohistochemical findings, 67‐year‐old female. Complete surgical removal tumor preservation sublingual was implemented...
Purpose: The study aimed to propose a new single‐plane fluoroscopy‐to‐CT registration method integrated with intervertebral anticollision constraints for measuring three‐dimensional (3D) kinematics of the spine; and evaluate performance without three variations via an in vitro experiment. Methods: proposed approach, called weighted edge‐matching (WEMAC) method, was based on integration geometrical adjacent vertebrae score (WEMS) that matched digitally reconstructed radiographs CT models...
Measurements of the morphology ankle joint, performed mostly for surgical planning total arthroplasty and collecting data prosthesis design, are often made on planar radiographs, therefore can be very sensitive to positioning joint during imaging. The current study aimed compare morphological measurements using CT-generated 2D images with gold standard values obtained from 3D CT data; determine sensitivity mal-positioning imaging; quantify repeatability under simulated conditions involving...
Accurate measurement of the three-dimensional (3D) motion mandible in vivo is essential for relevant clinical applications. Existing techniques are either limited accuracy or require use transoral devices that interfere with jaw movements. This study aimed to develop further an existing method measuring 3D, mandibular kinematics using single-plane fluoroscopy; determine method; and demonstrate its applicability via measurements on a healthy subject during opening/closing chewing...
Purpose: This study developed and assessed a slice‐to‐volume registration method that integrated three‐dimensional (3D) static MRI volumes of the bones with novel single‐slice, real‐time radial fast low‐angle shot for measuring 3D kinematics knee. Methods: Multislice images (for establishing bone models) 2D knee at five positions, during flexion/extension were acquired from three healthy adults. The poses, thus knee, obtained by registering to reformed slice interpolated models according...
Purposes To propose a new model‐based tracking method for measuring three‐dimensional (3D) dynamic joint kinematics using clinical alternating biplane x‐ray imaging system; and to quantify in vitro its errors ankle knee motions at different motion speeds. Methods A based on component partition interpolation (MCPI) was developed 3D system. Two detectors of the system placed perpendicular each other were operated collect fluoroscopic images targeted during tasks. The CT data also acquired...
Three-dimensional joint kinematics during canine locomotion are commonly measured using skin marker-based stereophotogrammetry technologies. However, marker-related errors caused by the displacement of surface relative to underlying bones (i.e., soft tissue artifacts, STA) may affect accuracy measurements and obscure clinically relevant information. Few studies have assessed STA in limbs kinematic analysis. The magnitudes patterns their influence on analysis remain unclear. Therefore,...
The measurement of mandibular kinematics is critical for studying the function temporomandibular joint (TMJ) and relevant clinical applications. However, none existing methods allows three-dimensional (3D) in vivo motion during dynamic functional movements without artifactual interference. purpose this study was to demonstrate feasibility a newly developed cone-beam computed tomography (CBCT)-based 3D fluoroscopic method differentiating rigid-body TMJ various activities. One healthy...

The contributions each rotational translational components were quantified through experiment-based...
Abstract Knowledge regarding the ligament footprints in canine stifle is essential for biomechanical modeling of joint and patient-specific surgical planning anatomical reconstruction. The present study aimed to establish evaluate deformable shape templates (DSTs) femur tibia with cruciate collateral ligaments embedded noninvasive estimation footprint positions. To this end, a data set computed tomography (CT)-derived surface models were established used build statistical (SSMs). contours...
Abstract Supernumerary teeth are relatively common in the maxillary incisor and molar areas. However, bilateral ectopic, fully erupted supernumerary mesiodentes rare. The present case documents a patient with localized periodontitis of first second molars associated bilaterally located proximity to buccal embrasure space between molars. Combined clinical data suggested that these ectopic predisposed or contributed development periodontitis.
Model-based tracking of the movement tibiofemoral joint via a biplane X-ray imaging system has been commonly used to reproduce its accurate, three-dimensional kinematics. To accommodate approaches existing clinical asynchronous fluoroscopy systems and achieve comparable accuracy, this study proposed an automated model-based interleaved image scheme (MIBFT) by incorporating information adjacent frames. The MIBFT was evaluated with cadaveric conducted on knee specimen. reproduced skeletal...
