A Novel Ensemble Framework for Multi-Classification of Brain Tumors Using Magnetic Resonance Imaging.

Brain tumors can have fatal consequences, affecting many body functions. For this reason, it is essential to detect brain tumor types accurately and at an early stage to start the appropriate treatment process. Although convolutional neural networks (CNNs) are widely used in disease detection from medical images, they face the problem of overfitting in the training phase on limited labeled and insufficiently diverse datasets.

Comparison of the effects of fluoxetine and venlafaxine on bone healing in a rat calvarial defect model.

Objective: The purpose of this study was to compare the effects of the selective serotonin reuptake inhibitor (SSRI) fluoxetine and the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine on bone defect healing.

Materials And Methods: Wistar rats were randomly divided into three groups of eight animals each. The first received 0.

The potential clinical relevance of anatomical structures and variations of the maxillary sinus for planned sinus floor elevation procedures: A retrospective cone beam computed tomography study.

Background: Complications arising from sinus floor elevation (SFE) with lateral approach surgery can be avoided by means of maxillary sinus examination in the preoperative period.

Purpose: To investigate anatomical variations in the maxillary sinus by making use of cone beam computed tomography (CBCT) in terms of SFE with a lateral approach.

Materials And Methods: Two hundred twenty eight maxillary sinuses in 114 patients were included.

Local treatment of chronic osteomyelitis with surgical debridement and tigecycline-impregnated calcium hydroxyapatite: an experimental study.

Objective: The aim of this study was to determine the efficacy of tigecycline-impregnated hydroxyapatite in the local treatment of chronic osteomyelitis experimentally induced in rat tibias with methicillin-resistant Staphylococcus aureus.

Study Design: Monocortical defects were established in the left tibias of 32 adult Wistar albino rats. Five rats were randomly selected and injected intramedullarly with saline solution (group 1), whereas chronic osteomyelitis was induced in other rats by intramedullary injection of S.

The use of 808-nm light therapy to treat experimental chronic osteomyelitis induced in rats by methicillin-resistant Staphylococcus aureus.

Background Data: In vivo and in vitro studies have reported that laser energy in differing wavelengths and irradiation regimes has a potential bactericidal effect on Staphylococcus aureus.

Objective: The purpose of this study was to investigate whether a light wavelength of 808  nm in varying doses has an effect on chronic osteomyelitis induced experimentally in the rat tibia.

Methods: Intramedullary cavities were surgically created in the left tibias of 39 adult Wistar albino rats.

Effect of tadalafil on renal resistivity and pulsatility index in partial ureteral obstruction.

Introduction: To investigate the effect of tadalafil on Resistivity Index (RI) and Pulsatility Index (PI) in partial unilateral ureteral obstruction (PUUO).

Methods: Twelve New Zealand rabbits were assigned into two groups. Baseline renal Doppler ultrasonography (USG) was performed in all rabbits.

Evaluation of free radical formation associated with diagnostic ultrasound.

Our objective was to evaluate kidney antioxidant status in rats subjected to an ultrasound examination. Thirty rats were divided into five groups for injection of saline (S) or anesthetic (A), and application of ultrasound using different modes, B mode, pulsed wave Doppler, and continuous wave Doppler, under anesthesia. Ultrasound was performed on days 1, 3, and 5 relative to the initiation of the experiment.
