Characterization of locomotor response to psychostimulants in the parthenogenetic marbled crayfish (Procambarus fallax forma virginalis): A promising model for studying the neural and molecular mechanisms of drug addiction.

Behav Brain Res 2018 Dec 11. Epub 2018 Dec 11.

J.P. Scott Center for Neuroscience, Mind & Behavior, and Department of Biological Sciences, Bowling Green State University, Bowling Green, OH 43403, USA.

Although scientific research using mammalian models has made great strides in uncovering the enigmatic neural and molecular mechanisms orchestrating the state of drug addiction, a complete understanding has thus far eluded researchers. The complexity of the task has led to the use of invertebrate model systems to complement the research of drug-induced reward in mammalian systems. Invertebrates, such as crayfish, offer excellent model systems to help reveal the underlying mechanisms of drug addiction as they retain the ancestral neural reward circuit that is evolutionarily conserved across taxa, and they possess relatively few, large neurons, laid out in an accessible, modularly organized nervous system.

Dimethyl fumarate ameliorates acetaminophen-induced hepatic injury in mice dependent of Nrf-2/HO-1 pathway.

Life Sci 2018 Dec 11. Epub 2018 Dec 11.

Department of Biochemistry, Faculty of Pharmacy, Mansoura University, Mansoura 35516, Egypt. Electronic address:

Drug-induced liver toxicity is the most frequent cause of acute liver failure worldwide. Hepatotoxicity caused by acetaminophen (ACT) overdose is mediated by its metabolic product promoting oxidative stress and activation of inflammatory mediators. Nuclear factor erythroid-related factor-2 (Nrf-2) induces the release of cytoprotective enzymes in response to electrophilic or oxidative stress and is considered a promising therapeutic target.

Eosinophilia associated with dobutamine allergy causes eosinophilic endomyocarditis confirmed by serial endomyocardial biopsies.

J Cardiol Cases 2012 Dec 19;6(6):e179-e182. Epub 2012 Sep 19.

Department of Cardiovascular Medicine, Heart Failure Division, National Cerebral and Cardiovascular Center, 5-7-1 Fujishiro-dai, Suita 565-8565, Japan.

We report a case of eosinophilic endomyocarditis caused by eosinophilia due to dobutamine allergy and successfully treated by a short-term and medium-dose steroid administration. Serial endomyocardial biopsies were useful for early diagnosis and evaluation of the effect of the treatment. Eosinophilic endomyocarditis due to dobutamine allergy is a rare entity; however, because of the high utilization rate of dobutamine in patients with low output heart failure, it is important to recognize that additional deterioration of cardiac function caused by eosinophilic endomyocarditis makes prognosis poor and early intervention is necessary.

Strategy for monitoring decompensated heart failure treated by an oral vasopressin antagonist with special reference to the role of serum chloride: A case report.

J Cardiol Cases 2016 Dec 9;14(6):185-188. Epub 2016 Sep 9.

Division of Internal Medicine and Pharmacy, Nishida Hospital, Oita, Japan.

Compared with conventional diuretic therapy, monitoring decompensated heart failure (HF) under treatment with a vasopressin antagonist is problematic because (1) use of this medication usually allows the patient free water intake to prevent drug-induced hypernatremia and (2) this medication often induces only minimal changes in the hemodynamics and blood concentration. In a 68-year-old female HF patient, use of tolvaptan did not induce much change in the urine output, presumably because of the low water intake due to a lack of thirst, but she did achieve a profound weight loss. Both the changes in chloride and sodium were negatively correlated with changes in the hemoglobin and serum creatinine, and positively correlated with changes in the mean red blood cell volume, but changes in the serum chloride were better correlated with each variable than were changes in the serum sodium.

Drug-Induced Expression-Based Computational Repurposing of Small Molecules Affecting Transcription Factor Activity.

Methods Mol Biol 2019 ;1903:179-184

Department of Physiology and Biophysics, Institute for Computational Biomedicine, Weill Cornell Medicine, New York, NY, USA.

Inhibition of oncogenes and reactivation of tumor suppressors are well-established goals in anticancer drug development. Unfortunately many oncogenes and tumor suppressors are not classically druggable, in that they lack a targetable enzymatic activity and associated binding pockets that small molecule drugs can be directed to. This is especially relevant for transcription factors, which have long been thought to be undruggable. Read More

Lysosomotropic drugs activate TFEB via lysosomal membrane fluidization and consequent inhibition of mTORC1 activity.

Cell Death Dis 2018 Dec 13;9(12):1191. Epub 2018 Dec 13.

The Fred Wyszkowski Cancer Research Laboratory, Technion-Israel Institute of Technology, Haifa, Israel.

Transcription factor EB (TFEB) is a master transcriptional regulator playing a key role in lysosomal biogenesis, autophagy and lysosomal exocytosis. TFEB activity is inhibited following its phosphorylation by mammalian target of rapamycin complex 1 (mTORC1) on the surface of the lysosome. Phosphorylated TFEB is bound by 14-3-3 proteins, resulting in its cytoplasmic retention in an inactive state. Read More

Biomarkers of drug-induced kidney toxicity.

Ther Drug Monit 2018 Dec 10. Epub 2018 Dec 10.

Division of Renal Diseases and Hypertension, University of Colorado at Denver, Aurora, CO.

Blood urea nitrogen (BUN) and serum creatinine are imperfect markers of kidney function because they are influenced by many renal and non-renal factors independent of kidney function. A biomarker that is released directly into the blood or urine by the kidney in response to injury may be a better early marker of drug-induced kidney toxicity than BUN and serum creatinine. Urine albumin and urine protein, as well as urinary markers kidney injury molecule-1 (KIM-1), β2-microglobulin (B2M), cystatin C, clusterin, and trefoil factor-3 (TFF-3) have been accepted by the Food and Drug Administration (FDA) and European Medicines Agency as highly sensitive and specific urinary biomarkers to monitor drug-induced kidney injury in preclinical studies and on a case-by-case basis in clinical trials.

Purpose: To determine if drug-induced peroxisome proliferator-activated receptor α (PPARα) signal pathway modulation affects refractive development and myopia in guinea pigs.

Methods: Pigmented guinea pigs were randomly divided into normal vision (unoccluded) and form deprivation myopia (FDM) groups. Each group received daily peribulbar injections of either a vehicle or (1) PPARα agonist, GW7647, clofibrate, or bezafibrate or (2) PPARα antagonist, GW6471, for 4 weeks. Read More

Loss of ARHGEF1 causes a human primary antibody deficiency.

J Clin Invest 2018 Dec 6. Epub 2018 Dec 6.

ARHGEF1 is a RhoA-specific guanine nucleotide exchange factor expressed in hematopoietic cells. We used whole-exome sequencing to identify compound heterozygous mutations in ARHGEF1, resulting in the loss of ARHGEF1 protein expression in two primary-antibody-deficient siblings presenting with recurrent severe respiratory tract infections and bronchiectasis. Both ARHGEF1-deficient patients showed an abnormal B cell immunophenotype, with a deficiency in marginal-zone and memory B cells and an increased frequency of transitional B cells. Read More

Combined effect of GABA and GLP-1 receptor agonist on cytokine-induced apoptosis in pancreatic β-cell lines and isolated human islets.

J Diabetes 2018 Dec 5. Epub 2018 Dec 5.

Division of Endocrinology and Metabolism, Keenan Research Centre for Biomedical Science, St. Michael's Hospital, Toronto, Ontario, Canada.

Background: Gamma-aminobutyric acid (GABA) or glucagon-like peptide-1 (GLP-1) treatment can preserve pancreatic β-cell mass and prevent diabetes. Recently, we reported that the combination of GABA and sitagliptin (a dipeptidyl peptidase-4 inhibitor that increases endogenous GLP-1) was more effective than either agent alone in reducing drug-induced β-cell damage and promoting β-cell regeneration in mice. However, in human islets, it remains unclear whether GABA and GLP-1 exert similar effects. Read More

Co-existence of Rolandic and 3 Hz Spike-Wave Discharges on EEG in Children with Epilepsy.

Can J Neurol Sci 2018 Dec 3:1-7. Epub 2018 Dec 3.

1Department of Pediatrics, Division of Neurology,BC Children's Hospital,Vancouver, British Columbia,Canada.

Objective: Benign epilepsy of childhood with central temporal spikes (BECTS) and absence epilepsy are common epilepsy syndromes in children with similar age of onset and favorable prognosis. However, the co-existence of the electrocardiogram (EEG) findings of rolandic spike and 3 Hz generalized spike-wave (GSW) discharges is extremely rare, with few cases reported in the literature. Our objective was to characterize the EEG findings of these syndromes in children in our center and review the electro-clinical features. Read More
