Quantification of vitamin D and 25-hydroxyvitamin D in food - The impact of eluent additives and labelled internal standards on matrix effects in LC-MS/MS analysis.

Food Chem 2021 Mar 13;357:129588. Epub 2021 Mar 13.

National Food Institute, Technical University of Denmark, Research Group for Bioactives - Analysis and Application, Kemitorvet, 2800 Kgs. Lyngby, Denmark. Electronic address:

Deuterated vitamin D standards are used commonly as internal standards in LC-MS/MS analysis of vitamin D and 25-hydroxyvitamin D in food. However, the use of various eluent additives, such as methylamine, formic acid and ammonium formate, also contributes to matrix effects and the performance of analysis by affecting accuracy and robustness. For the first time, continuous post-column infusion experiments of isotopically labelled vitamin D-[d] were performed to evaluate ion-suppression in a wide variety of food (salmon, cheese, pork fat, pork meat, and egg yolk).

Subvisible Particles in Solutions of Remicade in Intravenous Saline Activate Immune System Pathways in In Vitro Human Cell Systems.

J Pharm Sci 2021 Apr 14. Epub 2021 Apr 14.

Department of Pharmaceutical Sciences, University of Colorado, Anschutz Medical Campus, Aurora, Colorado, 80045. Electronic address:

Among patients that receive Remicade® therapy, more than 20% have adverse infusion related reactions and approximately 50% have immunogenic responses. Upon characterization of initial Remicade®-IV solution we observed a high concentration of subvisible particles that could inadvertently be delivered to patients. This solution was processed through the IV infusion system, mimicking the typical clinical administration setup - either with or without an in-line filter connected to the IV line. Read More

Neuroprotective and antioxidative effects of pioglitazone in brain tissue adjacent to the ischemic core are mediated by PI3K/Akt and Nrf2/ARE pathways.

J Mol Med (Berl) 2021 Apr 16. Epub 2021 Apr 16.

Institute of Experimental and Clinical Pharmacology, Faculty of Medicine, University Hospital of Schleswig-Holstein, Campus Kiel, Arnold Heller Strasse 3, 24105, Kiel, Germany.

The present study elucidates the neuroprotective mechanisms of the PPARγ (peroxisome proliferator-activated receptor γ) agonist pioglitazone in survival of ischemic neurons following middle cerebral artery occlusion with reperfusion (MCAO). Intracerebroventricular infusion of pioglitazone over 5 days before and 24 or 48 h after MCAO alleviated neurological impairments, inhibited apoptosis 24 h, and activated the PI3K/Akt pathway along with increased phosphorylation of Akt (ser473) and GSK-3β (ser9) in the peri-infarct cortical areas 48 h after MCAO. In primary cortical neurons, pioglitazone suppressed the glutamate-induced release of lactate dehydrogenase by a PPARγ-dependent mechanism. Read More

Effects of once-yearly zoledronic acid on bone density and incident vertebral fractures in nonmetastatic castration-sensitive prostate cancer patients with osteoporosis.

BMC Cancer 2021 Apr 17;21(1):422. Epub 2021 Apr 17.

Department of Palliative Medicine, Juntendo University Graduate School of Medicine, 2-1-1 Hongo, Bunkyo-ku, Tokyo, 113-8421, Japan.

Background: Androgen deprivation therapy (ADT) is the effective treating prostate cancer but is often accompanied by cancer treatment-induced bone loss (CTIBL), which impairs the patient's quality of life. In patients with nonmetastatic castration-sensitive prostate cancer (M0CSPC) who already have osteoporosis before starting ADT, appropriate bone-modifying agent intervention must be performed in parallel, as the patient has a high risk of future fracture. However, little is known about therapeutic interventions aimed at preventing the progression of CTIBL and new fractures. Read More

Authors:
Matt Shirley

Drugs 2021 Apr 16. Epub 2021 Apr 16.

Springer Nature, Mairangi Bay, Private Bag 65901, Auckland, 0754, New Zealand.

Casimersen (Amondys 45™) is an antisense oligonucleotide of the phosphorodiamidate morpholino oligomer subclass developed by Sarepta Therapeutics for the treatment of Duchenne muscular dystrophy (DMD) in patients who have a mutation in the DMD gene that is amenable to exon 45 skipping. Administered by intravenous infusion, casimersen is designed to bind to exon 45 of the DMD gene pre-mRNA, resulting in skipping of this exon during mRNA processing, intended to allow for production of an internally truncated but functional dystrophin protein in patients with DMD. Casimersen received its first approval on 25 February 2021, in the USA, for the treatment of DMD in patients who have a confirmed mutation of the DMD gene that is amenable to exon 45 skipping.

Pinocembrin attenuates hemorrhagic transformation after delayed t-PA treatment in thromboembolic stroke rats by regulating endogenous metabolites.

Acta Pharmacol Sin 2021 Apr 15. Epub 2021 Apr 15.

Beijing Key Laboratory of Drug Targets Identification and Drug Screening, Centre for Pharmaceutical Screening, Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, 100050, China.

Hemorrhagic transformation (HT) is a common serious complication of stroke after thrombolysis treatment, which limits the clinical use of tissue plasminogen activator (t-PA). Since early diagnosis and treatment for HT is important to improve the prognosis of stroke patients, it is urgent to discover the potential biomarkers and therapeutic drugs. Recent evidence shows that pinocembrin, a natural flavonoid compound, exerts anti-cerebral ischemia effect and expands the time window of t-PA. Read More

Randomized Trial of Interleukin-6 Receptor Inhibition in Patients With Acute ST-Segment Elevation Myocardial Infarction.

J Am Coll Cardiol 2021 Apr;77(15):1845-1855

Department of Cardiology, Oslo University Hospital Rikshospitalet, Oslo, Norway; K. G. Jebsen Cardiac Research Centre and Centre for Heart Failure Research, University of Oslo, Oslo, Norway; Faculty of Medicine, Institute of Clinical Medicine, University of Oslo, Oslo, Norway.

Background: Prompt myocardial revascularization with percutaneous coronary intervention (PCI) reduces infarct size and improves outcomes in patients with ST-segment elevation myocardial infarction (STEMI). However, as much as 50% of the loss of viable myocardium may be attributed to the reperfusion injury and the associated inflammatory response.
