The reciprocal function and regulation of tumor vessels and immune cells offers new therapeutic opportunities in cancer.

Semin Cancer Biol 2018 Jun 20. Epub 2018 Jun 20.

(a)VIB-Center for Cancer Biology, and KU Leuven, Department of Oncology, 3000 Leuven, Belgium; (b)Department of Neurological Surgery, Brain Tumor Research Center, Helen Diller Family Comprehensive Cancer Center, University of California, San Francisco, CA, 94158, USA. Electronic address:

Tumor angiogenesis and escape of immunosurveillance are two cancer hallmarks that are tightly linked and reciprocally regulated by paracrine signaling cues of cell constituents from both compartments. Formation and remodeling of new blood vessels in tumors is abnormal and facilitates immune evasion. In turn, immune cells in the tumor, specifically in context with an acidic and hypoxic environment, can promote neovascularization. Read More

Magnetic resonance imaging of arterial stroke mimics: a pictorial review.

Insights Imaging 2018 Jun 22. Epub 2018 Jun 22.

Department of Diagnostic and Therapeutic Neuroradiology, Hôpital Purpan, Place du Docteur Baylac, TSA 40031, 31059, Toulouse, France.

Acute ischaemic stroke represents the most common cause of new sudden neurological deficit, but other diseases mimicking stroke happen in about one-third of the cases. Magnetic resonance imaging (MRI) is the best technique to identify those 'stroke mimics'. In this article, we propose a diagnostic approach of those stroke mimics on MRI according to an algorithm based on diffusion-weighted imaging (DWI), which can be abnormal or normal, followed by the results of other common additional MRI sequences, such as T2 with gradient recalled echo weighted imaging (T2-GRE) and fluid-attenuated inversion recovery (FLAIR).

Euglycemic diabetic ketoacidosis caused by dapagliflozin: A case report.

Medicine (Baltimore) 2018 Jun;97(25):e11056

Department of Emergency Medicine, Chang Gung Memorial Hospital, Linkou.

Rationale: Diabetic ketoacidosis is a serious and potentially life-threatening acute complication of diabetes mellitus (DM). Euglycemic diabetic ketoacidosis (eDKA) is however challenging to identify in the emergency department (ED) due to absence of marked hyperglycemia, often leading to delayed diagnosis and treatment. eDKA has been recently found to be associated with sodium-glucose cotransporter 2 (SGLT2) inhibitors, one of the newest classes of antidiabetics, though there are very limited reports implicating dapagliflozin as the offending agent in ED patients.

Specific Inhibition of Hepatic Lactate Dehydrogenase Reduces Oxalate Production in Mouse Models of Primary Hyperoxaluria.

Mol Ther 2018 Jun 15. Epub 2018 Jun 15.

Dicerna Pharmaceuticals, Inc., Cambridge, MA 02140, USA. Electronic address:

Primary hyperoxalurias (PHs) are autosomal recessive disorders caused by the overproduction of oxalate leading to calcium oxalate precipitation in the kidney and eventually to end-stage renal disease. One promising strategy to treat PHs is to reduce the hepatic production of oxalate through substrate reduction therapy by inhibiting liver-specific glycolate oxidase (GO), which controls the conversion of glycolate to glyoxylate, the proposed main precursor to oxalate. Alternatively, diminishing the amount of hepatic lactate dehydrogenase (LDH) expression, the proposed key enzyme responsible for converting glyoxylate to oxalate, should directly prevent the accumulation of oxalate in PH patients.

Fatty and hydroxycarboxylic acid receptors: The missing link of immune response and metabolism in cattle.

Vet Immunol Immunopathol 2018 Jul 2;201:77-87. Epub 2018 Jun 2.

Laboratory of Molecular Pharmacology, Institute of Pharmacology, Faculty of Veterinary Science, Universidad Austral de Chile, Valdivia, Chile. Electronic address:

Fatty and hydroxycarboxylic acids are one of the main intermediates of energy metabolism in ruminants and critical in the milk production of cattle. High production demands on a dairy farm can induce nutritional imbalances and metabolism disorders, which have been widely associated with the onset of sterile inflammatory processes and increased susceptibility to infections. The literature suggests that short-chain fatty acids (SCFA), long-chain fatty acids (LCFA) and hydroxycarboxylic acids are relevant modulators of the host innate inflammatory response. Read More

Nutrients 2018 Jun 16;10(6). Epub 2018 Jun 16.

Division of Nephrology and Hypertension, Department of Medicine, Mayo Clinic, School of Medicine, Rochester, MN 55905, USA.

The popular modern diet, characterized by an excess of animal protein and salt but insufficient in fruits, vegetables and water, is a poor fit for human physiological and homeostatic regulatory systems. Sustained net acid and sodium retention, coupled with an insufficient intake of cardiovascular protective potassium-rich foods and hydration in the modern diet can give rise to debilitating chronic organ dysfunction and ultimately, mortality. This holds true, especially in our aging population who are already facing inevitable decline in organ functional reserve. Read More

Diagnosis and Treatment of Metabolic Acidosis in Patients with Chronic Kidney Disease - Position Statement of the Working Group of the Polish Society of Nephrology.

Kidney Blood Press Res 2018 Jun 7;43(3):959-969. Epub 2018 Jun 7.

Department of Nephrology, Transplantation and Internal Medicine, Medical University of Silesia, Katowice, Poland.

Metabolic acidosis is commonly found in patients with chronic kidney disease (CKD), and its causes are: impaired ammonia excretion, reduced tubular bicarbonate reabsorption and insufficient renal bicarbonate production in relation to the amount of acids synthesised by the body and ingested with food. As the consequence, numerous metabolic abnormalities develop, which may lead to dysfunction of several organs. In observational studies, it has been found that CKD patients with metabolic acidosis are characterised by faster progression of kidney disease towards end stage kidney failure, and by increased mortality.

H NMR metabolomics of microbial metabolites in the four MW agricultural biogas plant reactors: A case study of inhibition mirroring the acute rumen acidosis symptoms.

J Environ Manage 2018 Sep 9;222:428-435. Epub 2018 Jun 9.

Faculty of Civil and Geodetic Engineering, Hajdrihova 28, SI-1000, Ljubljana, Slovenia; Department of Animal Science, Biotechnical Faculty, University of Ljubljana, Ljubljana, Slovenia; Center for Clinical Neurophysiology, Faculty of Medicine, University of Ljubljana, Ljubljana, Slovenia. Electronic address:

In this study, nuclear magnetic resonance (H NMR) spectroscopic profiling was used to provide a more comprehensive view of microbial metabolites associated with poor reactor performance in a full-scale 4 MW mesophilic agricultural biogas plant under fully operational and also under inhibited conditions. Multivariate analyses were used to assess the significance of differences between reactors whereas artificial neural networks (ANN) were used to identify the key metabolites responsible for inhibition and their network of interaction. Based on the results of nm-MDS ordination the subsamples of each reactor were similar, but not identical, despite homogenization of the full-scale reactors before sampling. Read More

Improvement of 2-Vessel Occlusion Cerebral Ischaemia/Reperfusion-Induced Corticostriatal Electrolyte and Redox Imbalance, Lactic Acidosis and Modified Acetylcholinesterase Activity by Kolaviron Correlates with Reduction in Neurobehavioural Deficits.

Ann Neurosci 2018 Apr 23;25(1):53-62. Epub 2017 Nov 23.

Biochemical Pharmacology and Toxicology Laboratories, Department of Biochemistry, The Federal University of Technology, Akure, Nigeria.

Background: Disruption of electrolyte, redox and neurochemical homeostasis alongside cellular energy crisis is a hallmark of cerebral ischaemia and reperfusion injury.

Purpose: This study investigated the effect of kolaviron (KV) on cortical and striatal cation imbalance, oxidative stress and neurochemical disturbances as well as neurobehavioural deficits in animals subjected to bilateral common carotid artery occlusion (BCCAO)-induced ischaemia/reperfusion injury.

Methods: KV was administered at a dose of 100 or 200 mg/kg to male Wistar rats 1 h before a 30 min BCCAO/4 h reperfusion (I/R). Read More
