Prospective validation of podoplanin expression as a diagnostic biomarker of acute promyelocytic leukemia

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Acute promyelocytic leukemia (APL) is a medical emergency that needs immediate diagnosis and treatment. Podoplanin, a transmembrane glycoprotein that binds CLEC‐2 on platelets, was recently demonstrated to be abnormally expressed in leukemic blasts in APL, as opposed to other forms of AML, in a study using thawed primary cells.

University Exams and Psychosocial Stress: Effects on Cortisol Rhythmicity in Students

Clinical Endocrinology, EarlyView.
ABSTRACT Background University exams are recognised as naturalistic stressors that may elicit psychosocial and physiological responses in students. This pilot study investigated the short‐ and long‐term effects of exam‐related stress on hypothalamic–pituitary–adrenal (HPA) axis activity, focusing on cortisol production and rhythmicity.

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...
