An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

open access: yesAdvanced Science, Volume 13, Issue 37, 3 July 2026.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

Kat5 cKO mouse replicates biological domain signatures associated with Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION Alzheimer's disease (AD) can be caused by autosomal‐dominant familial Alzheimer's disease (FAD) mutations in amyloid precursor protein (APP) or presenilin‐1 and 2, which form an enzyme substrate complex. KAT5 binds to the APP intracellular domain.

Cervical Metastasis From Primary Breast Carcinoma: A Case Report and Review of Extragenital Tumors Involving the Uterine Cervix

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Cervical metastases from breast carcinoma should be considered in the differential diagnosis of uterine lesions in patients with prior breast cancer. Re‐biopsy is essential to detect receptor discordance (ER/PR up to 29%) and guide therapy. GCDFP‐15, mammaglobin, and GATA3 confirm mammary origin.

Advanced Uterine Carcinosarcoma With Fatal Suspected Pulmonary Embolism in a Resource‐Limited Setting: A Rare Case Report

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Uterine carcinosarcoma (UCS), also known as malignant mixed Müllerian tumor (MMMT), is a biphasic neoplasm characterized by the presence of carcinomatous (epithelial) and sarcomatous (stromal tissue) elements. It frequently presents at an advanced stage and can mimic primary ovarian carcinoma on clinical and radiological evaluation ...

The Challenge of Determining the Etiology of Encephalopathy in an Elderly Patient

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Encephalopathy is a heterogeneous clinical syndrome with numerous neurological and systemic etiologies. We report the case of a 67‐year‐old man, a chronic ethanol consumer, admitted with a one‐week history of confusional syndrome. Initial laboratory tests revealed severe hypercalcemia, acute kidney injury, mild anemia, and hyperproteinemia ...
