Age- and Sex-Related Volumetric Density Differences in Trabecular and Cortical Bone of the Proximal Femur in Healthy Population.

Background: There are age- and sex-related increases in the prevalence of osteoporosis. Bone densitometry based on dual energy X-ray absorptiometry (DXA) is the gold standard for the assessment of bone mineral density (BMD). Three-dimensional (3D) analysis of the proximal femur (3D-DXA) allows discrimination between cortical and trabecular compartments, and it has shown a good correlation with computed tomography.

'Becoming and being online EFL teachers': Teachers' professional identity in online pedagogy.

Teaching online may require teachers to shift to and display a professional identity different from the ones they held in face-to-face classroom teaching. Drawing upon the concept of teacher professional identity (TPI) and employing narrative inquiry as a method, the present study examines how two English as a foreign language (EFL) teachers display their professional identity through reflexivity as they shift experiences of being and becoming online teachers. It also explored how such identity is developed among EFL teachers in Thailand throughout their online teaching experience.

TikTok for language teachers: Affordances of TikTok on teachers' identity and emotional vulnerability.

This qualitative study examines how five secondary school TESOL teachers in Thailand use TikTok to express their emotions and shape their professional identities.

Findings indicate that TikTok helps teachers manage work-related stress and allows them to present authentic selves, facilitating deeper connections with students.

Esophageal tumors: The keys to diagnosis by pneumo-computed tomography.

Objective: To review and describe the most characteristic radiological findings of the most frequent esophageal tumor lesions, with emphasis on the esophago-gastric distention technique pneumo-computed tomography performed in our institution. To know the main advantage of this distension technique.

Conclusion: Malignant tumor lesions (predominantly squamous cell carcinoma in the mid esophagus and adenocarcinoma in the distal esophagus) present as asymmetric wall thickening, mucosal irregularity, or mass extending into adjacent organs with lymph node involvement.
