Titanium dioxide nanoparticles - physicochemical characterization and cytotoxic risk.

Titanium dioxide (TiO) nanoparticles (NPs) are incorporated into numerous consumer products yet data as to potential adverse health effects remains inconclusive. In this paper we physically characterize 16 nanoforms of TiO from different manufacturers of different size, crystalline structure and with surface chemistry. Physical measurements of the particles were performed and compared with those provided by manufacturers revealing several discrepancies.

Acute beneficial effects of a functional energy shot on cognitive performance and mood states during cognitively demanding task performance: a randomized, double-blind, placebo-controlled, crossover trial.

Introduction: Functional beverages are increasingly popular but it is important to validate their purported effects through research. The aim of the current study was to investigate the effects of a new functional energy shot on cognitive performance and mood states in healthy adults, with a focus on measuring mental energy enhancement and attenuation of negative effects associated with extended performance of mentally demanding tasks.

Methods: This study was a randomized, double-blind, placebo-controlled, crossover trial.

A Simplified Model of Adenine-Induced Chronic Kidney Disease Using SKH1 Mice.

Commonly used adenine-induced chronic kidney disease (CKD) murine models often employ C57BL/6 mice; however, this strain has inherent limitations due to its natural resistance to developing key pathological features of CKD, such as tubulointerstitial fibrosis and inflammation. There have been attempts to overcome these barriers by using multiple concentrations of adenine-supplemented diets or by performing prolonged experiments up to 20 weeks. Here, we demonstrate that SKH1 Elite mice develop clinically relevant CKD phenotypes (e.

Position statement on the diagnosis and management of acute leukaemia and aggressive lymphomas in pregnancy.

Haematological malignancies affect 12·5 in 100 000 pregnancies. Over the past two decades, the number of haematological malignancies in pregnancy has substantially increased. Life-threatening haematological malignancies in pregnancy, such as acute leukaemia and aggressive lymphomas, pose a unique therapeutic challenge: clinicians must consider both maternal and fetal wellbeing, aiming to deliver optimal curative therapy for the patient and a successful pregnancy outcome.
