Background: True exfoliation of the lens capsule is rare, and its occurrence with pseudoexfoliation in the same eye is very unusual.
Case Report: An 81-year-old female presented with bilateral cataracts and a history of working with ceramics in her home kiln. Slit-lamp examination revealed pseudoexfoliation. She underwent intracapsular cataract extraction and sector iridectomy in both eyes. Light and electron microscopy of the lenses revealed a central area of splitting of the anterior lens capsule into a thin anterior and a thicker posterior layer, and deposits pseudoexfoliation material on the anterior lens capsule, on the iris pigment epithelium, and in the iris stroma.
Conclusions: We interpret our findings as representing a combination of true exfoliation and pseudoexfoliation, but we did not observe any signs that might indicate a correlation or a common pathogenesis of the two conditions. Although they may occur in one eye, true exfoliation of the lens capsule and pseudoexfoliation are two unrelated distinct entities.

Introduction: Beta-thalassemia major is a blood disorder caused by impaired synthesis of hemoglobin beta chain. Oral manifestations of beta-thalassemia major in pregnancy have rarely been reported.
Objective: This study aimed to describe a case of oral manifestations in a pregnant woman with beta-thalassemia major for multidisciplinary management.

Article Synopsis
- The study addresses the challenge of inconsistent labeling in medical images, which affects diagnosis using deep learning models, particularly for oral exfoliative cytology.
- Researchers developed a convolutional neural network (CNN) by using annotations from multiple oral pathologists, processing six whole-slide images into 14,535 labeled tiles.
- The probabilistic model outperformed other approaches, achieving the highest classification performance and accuracy, suggesting that this method could enhance the reliability of AI in capturing diverse medical diagnoses.

Heterostructures (HSs) formed by the transition-metal dichalcogenide materials have shown great promise in next-generation (opto)electronic applications. An artificially twisted HS allows us to manipulate the optical and electronic properties. In this work, we introduce the understanding of the energy transfer (ET) process governed by the dipolar interaction in a twisted molybdenum diselenide (MoSe) homobilayer any charge-blocking interlayer.
