TRPS1 expression in breast angiosarcoma.

Angiosarcoma (AS) of the breast, a rare mesenchymal neoplasm, exhibits distinct forms based on etiological and genetic features. While cases with typical clinical presentation and morphology allow for a straightforward diagnosis, challenges arise when clinical data are scarce, diagnostic material is limited, or morphological characteristics overlap with other tumors, including undifferentiated carcinomas. The trichorhinophalangeal syndrome protein 1 (TRPS1), once regarded as highly specific for breast carcinomas, now faces doubts regarding its reliability.

Comparative analysis of EZH2, p16 and p53 expression in uterine carcinosarcomas.

The role of p16 and p53 immunohistochemistry in the diagnosis of rare and aggressive uterine carcinosarcoma (UCS) has been well established. However, enhancer of zeste homolog 2 (EZH2), a histone methyltransferase and a member of the polycomb group family is a relatively new biomarker, with limited published data on its significance in this tumor type. The goal of this study was to examine EZH2 expression in UCS and its components, in correlation with morphological features, and p16 and p53 staining patterns.

A systems biological analysis of the ATF4-GADD34-CHOP regulatory triangle upon endoplasmic reticulum stress.

Endoplasmic reticulum (ER) stress-dependent accumulation of incorrectly folded proteins leads to activation of the unfolded protein response. The role of the unfolded protein response (UPR) is to avoid cell damage and restore the homeostatic state by autophagy; however, excessive ER stress results in apoptosis. Here we investigated the ER stress-dependent feedback loops inside one of the UPR branches by focusing on PERK-induced ATF4 and its two targets, called CHOP and GADD34.

[Diagnostic difficulties and therapeutic options of a giant chest paraganglioma].

Paragangliomas are mostly benign tumors originating from the sympathetic or parasympathetic ganglions, but malignant forms are also known. They are in the region of the head and neck, in the glomus caroticum, intra-abdominally as well as in the thorax. The investigation of the 39-year-old male patient began due to extremely high blood pressure, night sweats and a 10 kg weight loss.

This study aims to test computer-aided diagnosis (CAD) for thyroid nodules in clinical ultrasonography (US) practice with a focus towards identifying thyroid entities associated with CAD system misdiagnoses. Two-hundred patients referred to thyroid US were prospectively enrolled. An experienced radiologist evaluated the thyroid nodules and saved axial images for further offline blinded analysis using a commercially available CAD system.

Interprofessional team-based learning (TBL): how do students engage?

Background: Although challenging to integrate within university curricula, evidence suggests that interprofessional education (IPE) positively impacts communication and teamwork skills in the workplace. The nature of Team-based learning (TBL) lends itself to interprofessional education, with the capacity to foster a culture of collaboration among health professional students. Our study was designed to pilot an interprofessional 'back pain' TBL module for physiotherapy and medical students, and to explore their experience of the TBL process, using the conceptual framework of 'knowledge reconsolidation' to discuss our finding.

Histology, 12p status, and IMP3 expression separate subtypes in testicular teratomas.

Introduction: Two types of testicular teratomas are distinguished by the current WHO classification. Prepubertal-type teratomas are benign, while postpubertal-type teratomas are considered malignant with metastatic potential, and are associated with germ cell neoplasia in situ. Prepubertal-type cases have been reported in the adult testis potentially causing confusion and overtreatment.
