Genome-wide expression profiling identifies deregulated miRNAs in malignant astrocytoma

open access: yes, 2010
Malignant astrocytoma includes anaplastic astrocytoma (grade III) and glioblastoma (grade IV). Among them, glioblastoma is the most common primary brain tumor with dismal responses to all therapeutic modalities.

Capturing Heterogeneous Time‐Variation in Covariate Effects in Non‐Proportional Hazard Regression Models

open access: yesBiometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT A central focus in survival analysis is examining how covariates affect survival time. These covariate effects are often found to be either time‐varying, heterogeneous—such as being specific to patients, treatments, or subgroups—or exhibit both characteristics simultaneously. While the standard model, the Cox proportional hazards model, allows

Variations in Human Trigeminal and Facial Nerve Branches and Foramina Identified by Dissection and Microcomputed Tomography

open access: yesClinical Anatomy, Volume 39, Issue 7, Page 738-746, October 2026.
ABSTRACT The aim of this study was to identify branches of the trigeminal and facial nerves (FNs) relevant to surgical incisions and injections and the scalp block techniques in the frontotemporal region, and to determine their relationships with superficial vascular structures and bony landmarks.

Establishment of Salivary Gland Tumors Arising in Salivary Gland‐Specific EWSR1::ATF1 Transgenic Mice

open access: yesHead &Neck, Volume 48, Issue 10, Page 2733-2744, October 2026.
ABSTRACT Background Salivary gland carcinomas are uncommon malignancies with various histological subtypes harboring fusion genes. The EWSR1::ATF1 fusion gene, resulting from a translocation between chromosomes 12 and 22, is frequently observed in hyalinizing clear cell carcinoma (HCCC). However, the role of this fusion gene in HCCC oncogenesis remains

Pilomyxoid astrocytoma showing malignant transformation in adult male

open access: yes, 2017
Pilomyxoid astrocytomas are type of tumors rarely seen in the central nervous system as a variant of pilocytic astrocytoma. They are often localized in hypothalamic-chiasmatic area and seen in early childhood.

Cancer Risk in Marfan Syndrome: A Swedish Population‐Based Cohort Study

open access: yesInternational Journal of Cancer, Volume 159, Issue 7, Page 1707-1714, 1 October 2026.
The cancer risk in Marfan syndrome, an autosomal dominant connective tissue disorder, largely remains to be explored. In this population‐based matched cohort study of 1544 Swedish patients, the overall cancer risk in adults with Marfan syndrome showed no significant increase, except for the risk of endocrine tumours with a nearly threefold increase ...
