Comparative evaluation of calretinin immunohistochemical expression in calcifying odontogenic cyst and ameloblastoma.
BMC Oral Health

Oral Health Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran.
Background: Calretinin is a 29 kilodalton (KDa) calcium-binding protein that is expressed in normal and tumoral tissues. The expression of calretinin has been shown in the dental epithelium during odontogenesis and in different odontogenic cysts and tumors such as ameloblastoma. Since the epithelium of calcifying odontogenic cyst (COC) is similar to ameloblastoma and in both lesions, an arrangement of loose cells similar to stellate reticulum is seen, we aimed to investigate the comparative expression of calretinin in COC and ameloblastoma.

BMC Med Educ
January 2025
University of Minnesota Medical School, 420 Delaware Street SE, Mayo Building, Minneapolis, MN, 55455, USA.
Background: A common practice in assessment development, fundamental for fairness and consequently the validity of test score interpretations and uses, is to ascertain whether test items function equally across test-taker groups. Accordingly, we conducted differential item functioning (DIF) analysis, a psychometric procedure for detecting potential item bias, for three preclinical medical school foundational courses based on students' sex and race.
Methods: The sample included 520, 519, and 344 medical students for anatomy, histology, and physiology, respectively, collected from 2018 to 2020.
The enlarged perivascular spaces in the hippocampus is associated with memory function in patients with type 2 diabetes mellitus.

Department of MRI, Shaanxi Provincial People's Hospital, Xi'an, China.
Early detection of cognitive dysfunction in patients with type 2 diabetes mellitus (T2DM) is important for preventive measures due to the lack of effective treatments. The purpose of this study is to investigate the relationship between enlarged perivascular space in the hippocampus (H-EPVS) and cognitive performance in patients with T2DM, and to determine whether it can serve as an imaging marker for cognitive dysfunction. 66 T2DM patients with cognitive impairment (T2DM-CI) and 71 T2DM patients with normal cognitive function (T2DM-NC) underwent cranial MRI scans and comprehensive neuropsychological assessments.

Gait Posture

Groupe de Recherche sur les Affections Neuromusculosquelettiques, Université du Québec à Trois-Rivières, Canada; Department of Human Kinetics, Université du Québec à Trois-Rivières, Canada; Center for Interdisciplinary Research in Rehabilitation and Social Integration (Cirris), Quebec, QC, Canada.
Background: Foot orthoses (FOs) are commonly prescribed to reduce pain and improve function in individuals with musculoskeletal disorders, including those with chronic metatarsalgia (CM). Reducing the mechanical overload under the metatarsal heads during locomotion is the central point of the treatment for CM. Medially wedged FOs (MWFOs) with a metatarsal pad could further reduce pressure loading under the metatarsal heads and modify foot and ankle biomechanics compared to standard FOs (SFOs).

Introduction: Anxiety is a prevalent psychological issue among cancer patients, significantly affecting their quality of life and potentially influencing treatment outcomes. This study aims to investigate the prevalence and associated factors of anxiety among cancer patients at the University of Gondar Comprehensive Specialized Hospital in Northwest Ethiopia.
Methods: A cross-sectional study design was used, involving 384 cancer patients, selected by systematic random sampling technique, from the oncology ward.
