Analysis of ADVIA Myeloperoxidase Cytogram LUC Angle Does Not Distinguish Acute Myeloid Leukemia From Acute Lymphoblastic Leukemia or Lymphoblastic Lymphoma in Dogs

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Background Acute myeloid leukemia (AML) is difficult to distinguish from lymphoblastic leukemia or lymphoma (LL) on morphologic features alone. Therapeutic approaches for AML versus LL differ, and immediate therapy is often needed due to patient illness and rapid disease progression.

Organocatalytic asymmetric Friedel-Crafts alkylation/cascade reactions of naphthols and nitroolefins

, 2007
The asymmetric Michael-type Friedet-Crafts reaction of naphthols and nitroolefins promoted by bifunctional thiourea-tertiary amine organocatalysts (up to 95% ee) was investigated; on simply extending the reaction time further cascade reactions could ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

GMP‐compliant production, validation and dosimetry of clinical grade [18F]3‐(3‐fluoropropyl)‐2‐phenyl‐2,3‐dihydrobenzo[d]thiazole ([18F]FPBT) for oxidative stress PET imaging

British Journal of Pharmacology, Volume 183, Issue 20, Page 6028-6045, October 2026.
Background and Purpose Oxidative stress plays a critical role in the pathophysiology of various diseases, yet current methods for its non‐invasive detection remain limited. This study aimed to systematically validate a superoxide‐selective PET tracer, [18F]FPBT, for the early diagnosis and therapeutic monitoring of oxidative stress‐related conditions ...
