The ciliary neurotrophic factor induces Stat3 phosphorylation in distinctive cytotypes of organs involved in body metabolism: An immunohistochemical study

Journal of Anatomy, EarlyView.
p‐STAT3‐positive cells in metabolically relevant peripheral organs and tissues from mice administered with recombinant CNTF (0.3 mg/kg). Abstract Administration of ciliary neurotrophic factor (CNTF) reduces food intake and body weight in both humans and experimental animals, where it also ameliorates hyperglycemia, hyperinsulinemia, and dyslipidemia ...

Implant stability quotient and osteogenic process in dental implant sites prepared using piezoelectric technique: A study in minipigs

Journal of Prosthodontics, EarlyView.
Abstract Purpose Few studies have explored the bone response in dental implant sites prepared using a piezoelectric device, indicating moderate effectiveness in enhancing secondary stability and osteogenesis. This study seeks to expand our understanding of the changes in biological, clinical, and radiographic parameters, during the initial phases of ...

π‐Extended COUPY Fluorophores for Targeted Near‐Infrared Fluorescence and Lifetime Imaging in Live Cells

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
π‐Extended COUPY dyes, obtained by vinylogation of coumarin‐based COUPY scaffolds, shift absorption, and emission deep into the NIR region while preserving compactness and synthetic accessibility. These bright, photostable dyes enable live‐cell imaging, FLIM, and site‐specific peptide conjugation, offering a modular platform for targeted bioimaging and

Simultaneous T2, T2*, and R2′ Mapping for Multiple Sclerosis Using Nonlinear Model‐Based Reconstruction of Undersampled Radial RARE‐EPI MRI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1872-1892, October 2026.
ABSTRACT Purpose To demonstrate the synergy of undersampled radial 2in1‐RARE‐EPI acquisition and nonlinear model‐based reconstruction for accelerated and simultaneous T2, T2*, and R2′ mapping in brains of patients with multiple sclerosis (MS). Methods 2in1‐RARE‐EPI combines a RARE module with an EPI module to capture T2 and T2* information.

Possible Contribution of Multiple Sclerosis Pathology to Treatment‐Resistant Schizophrenia: A Case Study

Neuropsychopharmacology Reports, Volume 46, Issue 3, September 2026.
A case of multiple sclerosis detected by brain MRI during evaluation for modified electroconvulsive therapy in the long‐term course of schizophrenia. This case discusses the clinical overlap between multiple sclerosis pathology and treatment‐resistant schizophrenia. ABSTRACT Multiple sclerosis (MS) can present with neurological and psychiatric symptoms

The Neurovascular Niche: A Gathering Venue for Neuroinflammation and Remyelination in Multiple Sclerosis

Acta Physiologica, Volume 242, Issue 9, September 2026.
ABSTRACT In the central nervous system (CNS), the tissue microenvironment is continuously monitored and regulated to secure the unobstructed function of neurons and of their networks. This is a key function of the neurovascular niche (NVN), which is the interface between the cells of the nervous tissue and the cells and the content of blood vessels. It

Incidence of Hepatitis B Virus Reactivation in Patients Treated With Immunosuppressive and Chemotherapeutic Agents

Alimentary Pharmacology &Therapeutics, Volume 64, Issue 5, Page 625-634, September 2026.
HBV reactivation incidence varied across immunosuppressive and chemotherapeutic agents. Clinically meaningful HBV reactivation was also observed in patients receiving corticosteroids and conventional immunosuppressive therapies. ABSTRACT Background Data on the incidence of hepatitis B virus reactivation (HBVr) remain limited. In Japan, patients who are
