Single‐molecule mechanochemical characterization of E. coli pol III core catalytic activity

Protein Science, Volume 26, Issue 7, Page 1413-1426, July 2017., 2017
Abstract Pol III core is the three‐subunit subassembly of the E. coli replicative DNA polymerase III holoenzyme. It contains the catalytic polymerase subunit α, the 3′ → 5′ proofreading exonuclease ε, and a subunit of unknown function, θ. We employ optical tweezers to characterize pol III core activity on a single DNA substrate.

Influência da heparina sódica na ocorrência de laminite eqüina induzida por sobrecarga de carboidratos Influence of heparin in occurrence of carbohydrate overload-induced equine laminitis

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2008
Avaliou-se a eficiência da infusão intravenosa de heparina sódica (100UI/kg/8h, a partir de 24h após o fornecimento de carboidrato, até completar 48h) no controle da laminite eqüina experimentalmente induzida por sobrecarga de carboidrato (17,6g de amido

Investigation of Luminescence Characteristics of Osmium(II) Complexes in the Presence of Heparin Polyanions

International Journal of Analytical Chemistry, Volume 2013, Issue 1, 2013., 2013
The luminescence characteristics of six osmium carbonyl complexes with phenanthroline (phen) or bipyridine (bpy) and pyridine (py), 4‐phenylpyridine (4‐phpy), or triphenylphosphine (PPh3) complexes in the presence of polyanion heparin were studied in both ethanol and aqueous solutions.

Physiologic Responses to Infrarenal Aortic Cross‐Clamping during Laparoscopic or Conventional Vascular Surgery in Experimental Animal Model: Comparative Study

Anesthesiology Research and Practice, Volume 2008, Issue 1, 2008., 2008
The aim of this study was to compare the hemodynamic and ventilatory effects of prolonged infrarenal aortic cross‐clamping in pigs undergoing either laparotomy or laparoscopy. 18 pigs were used for this study. Infrarenal aortic crossclamping was performed for 60 minutes in groups I (laparotomy, n = 6) and II (laparoscopy, n = 6). Group III (laparoscopy,

Computed Tomography Yield and Predictors of Pulmonary Embolism in Mechanically Ventilated Patients—A Retrospective Study

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 4, April 2026.
ABSTRACT Background The reported prevalence of pulmonary embolism (PE) detected during intensive care varies substantially. Computed tomography pulmonary angiography (CTPA) is the diagnostic reference method, but assessing pre‐test probability and finding distinct indications for CTPA from clinical observations is difficult in mechanically ventilated ...

Comparative Evaluation of Follicular Flushing Frequency and Scraping Time During Ovum Pick‐Up in Mares: Effects on Oocyte Recovery Rate and Technical Considerations

Reproduction in Domestic Animals, Volume 61, Issue 2, February 2026.
ABSTRACT Transvaginal ultrasound‐guided follicular aspiration or ovum pick‐up (OPU) has become the standard technique for oocyte collection in mares for intracytoplasmic sperm injection (ICSI). Although repeated follicular flushes and wall scraping are commonly used to improve oocyte recovery rate (ORR), the relative contribution of each remains ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, Volume 599, Issue 19, Page 2718-2749, October 2025.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...
