The magnetic resonance imaging (MRI) of the rat brain after the epilepsy seizures has been performed. As a first step, the model of the kainic acid (KA) induced seizures has been conducted to examine the possibilities of magnetic resonance imaging system kept in disposition. Seven Wistar albino rats, weighing about 300 g, were used in this study. We administered six of them with intraperitoneal injection of 10 mg/kg of KA. The control animal received corresponding volume of the saline. Every animal was examined under systemic anaesthesia induced by an intraperitoneal injection of thiopental sodium approximately 15 minutes before scanning. Diffusion-weighted imaging (DWI) has been used to acquire the coronary scans of the rat brain. The progress of hyper intense signal at the cerebral cortex and amygdale has been observed. Marked asymmetry of the signal intensity between hemispheres has been discovered. Subsequently the experimental model of audiogenic epilepsy will be conducted.

Comparative evaluation of left atrial size in healthy cats measured by two-dimensional echocardiography and cardiovascular MRI.
J Feline Med Surg
January 2025
College of Veterinary Medicine, China Agricultural University, Beijing, China.
Objectives: This study aimed to assess left atrial (LA) size in healthy cats using cardiovascular MRI (cMRI) and to compare this with LA size assessed by two-dimensional echocardiography. The hypothesis was that cMRI would accurately determine LA size in domestic cats.
Methods: A prospective comparative study was performed.
A child with Chronic Nonbacterial Osteomyelitis and celiac disease: accidental association or two different aspects of the same condition?
Ital J Pediatr

Department of Pediatrics, IRCCS Policlinico San Matteo Foundation, Viale Golgi 19, Pavia, 27100, Italy.
Background: Chronic Nonbacterial Osteomyelitis (CNO) is a rare auto-inflammatory disease that mainly affects children, and manifests with single or multiple painful bone lesions. Due to the lack of specific laboratory markers, CNO diagnosis is a matter of exclusion from different conditions, first and foremost bacterial osteomyelitis and malignancies. Whole Body Magnetic Resonance (WBMR) and bone biopsy are the gold standard for the diagnosis.

Arthritis Res Ther

Rheumazentrum Ruhrgebiet Herne, Ruhr University Bochum, Herne, Germany.
Background: Optical spectral transmission (OST) is a modern diagnostic method capable of quantifying inflammation in the finger and wrist joints of arthritis patients by assessing the blood-specific absorption of light transmitted through a tissue. The diagnostic performance of this modality has not been adequately examined and data regarding OST associations with magnetic resonance imaging (MRI) are limited. Aim of this study was therefore to investigate the performance of OST in assessing joint inflammation as compared to MRI in patients with inflammatory arthritis (IA).

Department of Orthopaedics and Traumatology, Taipei Veterans General Hospital, Taipei, Taiwan.
Purpose: This study aimed to assess the clinical and radiographic healing rates of the arthroscopic all-inside wrapping repair technique for lateral meniscus bucket-handle tears (LMBHTs).
Methods: This retrospective study examined patients diagnosed with LMBHTs who underwent all-inside wrapping repair with or without anterior cruciate reconstruction between 2012 and 2021. Patients with previous knee surgeries, multiligamentous knee injuries, or advanced osteoarthritis were excluded.
Multiomics unravels the complexity of male obesity: a prospective observational study.
J Transl Med
January 2025
Department of Endocrinology, Diabetology and Metabolism, Lausanne University Hospital, Avenue de la Sallaz 8, CH-1011, Lausanne, Switzerland.
Background: Obesity is associated with varying degrees of metabolic dysfunction. In this study, we aimed to discover markers of the severity of metabolic impairment in men with obesity via a multiomics approach.
Methods: Thirty-two morbidly men with obesity who were candidates for Roux-en-Y gastric bypass (RYGB) surgery were prospectively followed.
