Polarized effects of adenosine on blood–brain barrier integrity: Tightening from the luminal and opening from the abluminal side

British Journal of Pharmacology, Volume 183, Issue 16, Page 4761-4777, August 2026.
Background and Purpose Adenosine as a signalling molecule modifies blood–brain barrier (BBB) tightness in pathological conditions. Our aim was to investigate the direct and polarized effects of adenosine on the BBB using co‐culture and in vivo models. Experimental Approach The expression of adenosine receptors was measured by qRT‐PCR.

Vasculature of the Anterior Abdominal Wall and Surface Anatomy of the Liver and Stomach: Considerations for Minimal Access Surgeries in Neonates

Anatomia
Background: Minimal access surgeries are growing more common in neonatal care, but the risk of accidental injury to abdominal wall blood vessels remains a concern. This risk is increased by limited precise anatomical data specific to neonates. Therefore,

Immunophenotypic assessment of pure embryonal carcinoma and yolk sac tumour suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche

Histopathology, Volume 89, Issue 2, Page 303-311, August 2026.
Immunohistochemical analysis of transcription factors in GCNIS associated with pure EC and YST suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche. In these tumors, reprogramming may occur immediately upon invasion of the stroma or within seminiferous tubules but outside the spermatogonial niche (i.e., in intratubular ...

Can acromegaly be controlled in all cases?

Journal of Neuroendocrinology, Volume 38, Issue 8, August 2026.
Abstract Acromegaly is a rare disease, due in most of the cases to a growth hormone (GH)‐secreting pituitary adenoma (PA), namely neuroendocrine tumour (PitNET). The treatment of patients with acromegaly is multimodal and multi‐step, including surgery, medical therapies, and radiotherapy.

Multiple Rare Vascular Gastrointestinal Variations Present in a 97-Year-Old Female Donor: Clinical Relevance and Surgical Implications

Anatomia
Multiple rare vascular variations were identified in a 97-year-old female donor during the dissection of the gastrointestinal system. An anomalous middle colic artery originated from the celiac trunk alongside the three normal branches.

Auxin‐Dependent Activation of RHD6‐RSL4 Cascade Promotes Root Hair Growth Under Boron Deficiency in Arabidopsis Primary Root Apices

Plant, Cell &Environment, Volume 49, Issue 8, Page 6081-6099, August 2026.
ABSTRACT Plants rapidly adjust their root system architecture to enhance resource uptake and cope with fluctuating soil environments. One such adaptive response is the development of root hairs (RH), which increase the effective root surface area and thereby improve water and nutrient acquisition.

Clinical Anatomy of the Lower Extremity Veins—Topography, Embryology, Anatomical Variability, and Undergraduate Educational Challenges

Anatomia
Veins of the lower extremity can be categorized into three hierarchically ordered groups: the epifascial, the interfascial, and the deep ones. In the past, the interfascial veins, e.g., the great saphenous vein, were categorized as superficial veins. But

Anatomical and Histological Analyses of Rare Pancake Kidney

Anatomia
During anatomical dissection of a female body donor at the Howard University College of Medicine, a rare renal anomaly was discovered. Detailed anatomical and histological analyses on this anomaly were compared to a normal kidney from another donor and ...
