Multimodality Imaging in the Diagnosis and Staging of Gestational Choriocarcinoma.

Choriocarcinoma is an uncommon, highly invasive malignancy arising from the placental trophoblastic tissue. Though staging is clinical, imaging has significant role in the diagnosis, staging, prognostic risk scoring, and management of choriocarcinomas. The purpose of this article is to review the role of multimodality imaging in the diagnosis, staging, and management of choriocarcinomas in correlation with clinicopathologic findings.

Comparing new tools of artificial intelligence to the authentic intelligence of our global health students.

Introduction: The transformative feature of Artificial Intelligence (AI) is the massive capacity for interpreting and transforming unstructured data into a coherent and meaningful context. In general, the potential that AI will alter traditional approaches to student research and its evaluation appears to be significant. With regard to research in global health, it is important for students and research experts to assess strengths and limitations of GenAI within this space.

Development and validation of the premenstrual dysphoric disorder scale in Indian females.

Background: Premenstrual dysphoric disorder is a mood disorder that has been recognized in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5) as a subcategory of depressive disorders. The disorder has a high prevalence rate, and yet no uniform measure is standardized on the Indian population.

Aim: This study aimed to develop a scale to assess premenstrual dysphoric disorder that can be used for screening and for clinical use and that is standardized on the Indian population.

Phase-matched five-wave mixing in zinc oxide microwire.

High-order wave mixing in solid-state platforms gather increasing importance due to the development of advanced lasers and integrated photonic circuit for both classical and quantum information. However, the high-order wave mixing is generally inefficient in solids under weak pump. Here, we observed the presence of phase matching of five-wave mixing (5WM) propagating in a zinc oxide (ZnO) microwire.

Apoptotic signaling by TNFR1 is inhibited by the α2-6 sialylation, but not α2-3 sialylation, of the TNFR1 N-glycans.

The TNF-TNFR1 signaling pathway plays a pivotal role in regulating the balance between cell survival and cell death. Upon binding to TNF, plasma membrane-localized TNFR1 initiates survival signaling, whereas TNFR1 internalization promotes caspase-mediated apoptosis. We previously reported that the α2-6 sialylation of TNFR1 by the tumor-associated sialyltransferase ST6GAL1 diverts signaling toward survival by inhibiting TNFR1 internalization.
