Small scale purification and biophysical characterization of haptoglobin derived from human Cohn fraction IV

Biotechnology Progress, EarlyView.
Abstract Haptoglobin (Hp) is a polymorphic acute phase α‐2 glycoprotein found in plasma that plays a critical role in binding, neutralizing, and removing cell‐free hemoglobin (Hb) from the circulation. Under clinical conditions characterized by high levels of hemolysis, such as in patients with sickle cell disease (SCD), large quantities of cell‐free ...

Evaluation of nucleotide MALDI-TOF-MS for the identification of Mycobacterium species

Frontiers in Cellular and Infection Microbiology
BackgroundThe accurate identification of the Mycobacterium tuberculosis complex (MTBC) and different nontuberculous mycobacteria (NTM) species is crucial for the timely diagnosis of NTM infections and for reducing poor prognoses.

MALDI-TOF-MS spectra of AA-labelled N-linked glycans of F. hepatica NEJTeg before and after exoglycosidase treatments.

, 2016
N-glycans released from NEJTeg using PNG-F were labelled with fluorophore 2-aminobenzoic acid (2-AA). MS spectra of AA-labelled N-glycans were acquired by MALDI-TOF-MS without exoglycosidase treatment (A) and after α-mannosidase (B), β-N ...

Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

Chemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...

Synergistic Molecular Modulation of ππ Stacking for High‐Performance Pitch‐Derived Hard Carbon Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic molecular strategy is demonstrated to disrupt intrinsic ππ stacking in pitch, boosting 6‐fold sulfonation, yielding a hard carbon with 0.371 nm interlayer spacing and maximized closed pores, and achieving a high reversible capacity, remarkable rate capability (205.6 mAh g−1 at 2 A g−1) and cyclic stability.

Duct‐level evaluation of mammary gland health, somatic cell count and bacterial flora in lactating jennies

Equine Veterinary Journal, EarlyView.
Abstract Background Assessing mammary gland health in donkeys is challenging due to the lack of species‐specific diagnostic criteria for subclinical mastitis. Although somatic cell count (SCC) is widely used in dairy ruminants, its diagnostic value in jennies remains unclear.

Thirteen years of environmental surveillance of ESKAPE organisms and Escherichia coli in an equine hospital: Informing infection control

Equine Veterinary Journal, EarlyView.
Abstract Background Bacteria from the ESKAPE group (i.e., Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species) and Escherichia coli are frequently multidrug‐resistant and can be associated with healthcare‐associated infections, an increasing concern for veterinary ...
