Tranilast attenuates lipopolysaccharide‑induced lung injury via the CXCR4/JAK2/STAT3 signaling pathway.

Mol Med Rep 2022 Jul 18;26(1). Epub 2022 May 18.

Department of Emergency, The Affiliated Hospital of Medical School of Ningbo University, Ningbo, Zhejiang 315020, P.R. China.

It has been reported that the expression of C‑X‑C motif chemokine receptor 4 (CXCR4) is increased in patients with lung injury, while CXCR4 downregulation can improve sepsis‑induced lung injury. Previous studies have shown that tranilast can inhibit CXCR4 mRNA expression. Therefore, the present study aimed to investigate whether tranilast could protect against lipopolysaccharide (LPS)‑induced lung injury via the CXCR4/Janus kinase 2 (JAK2)/STAT3 signaling pathway.

Efficacy of lipid emulsion therapy in treating cardiotoxicity from diphenhydramine ingestion: a review and analysis of case reports.

Clin Toxicol (Phila) 2022 May 16;60(5):550-558. Epub 2022 Feb 16.

Department of Emergency Medicine, Division of Medical Toxicology, Boston Children's Hospital, Boston, MA, USA.

Introduction: Lipid emulsion therapy (LET) has been most thoroughly studied to reverse local anesthetic systemic toxicity (LAST). Case reports suggest that LET can successfully rescue cardiovascular collapse from bupropion, amitriptyline, and propranolol. The efficacy of LET against refractory hypotension and dysrhythmias from diphenhydramine, a commonly ingested lipophilic cardiotoxic agent, is less well described. Read More

In coastal systems, pollutants as pharmaceutical drugs exert changes from the molecular to the organism level in marine bivalves. Besides pollutants, coastal systems are prone to changes in environmental parameters, as the alteration of salinity values because of Climate Change. Together, these stressors (pharmaceutical drugs and salinity changes) can exert different threats than each stressor acting individually; for example, salinity can change the physical-chemical properties of the drugs and/or the sensitivity of the organisms to them.

The Interaction of Heptakis (2,6-di-O-Methyl)-β-cyclodextrin with Mianserin Hydrochloride and Its Influence on the Drug Toxicity.

Int J Mol Sci 2021 Aug 30;22(17). Epub 2021 Aug 30.

Unit of Biophysical Chemistry, Department of Physical Chemistry, Faculty of Chemistry, University of Lodz, Pomorska 165, 90-236 Lodz, Poland.

One tetracyclic antidepressant, mianserin hydrochloride (MIA), has quite significant side effects on a patients' health. Cyclodextrins, which are most commonly used to reduce the undesirable features of contained drugs within their hydrophobic interior, also have the potential to alter the toxic behavior of the drug. The present paper contains investigations and the characteristics of interaction mechanisms for MIA and the heptakis (2,6-di-O-methyl)-β-cyclodextrin (DM-β-CD) system, and evaluated the effects of the complexation on MIA cytotoxicity.

Increasing Angiogenesis Factors in Hypoxic Diabetic Wound Conditions by siRNA Delivery: Additive Effect of LbL-Gold Nanocarriers and Desloratadine-Induced Lysosomal Escape.

Int J Mol Sci 2021 Aug 26;22(17). Epub 2021 Aug 26.

Laboratory of General Biochemistry and Physical Pharmacy, Faculty of Pharmacy, Ghent University, Ottergemsesteenweg 460, 9000 Ghent, Belgium.

Impaired wound healing in people with diabetes has multifactorial causes, with insufficient neovascularization being one of the most important. Hypoxia-inducible factor-1 (HIF-1) plays a central role in the hypoxia-induced response by activating angiogenesis factors. As its activity is under precise regulatory control of prolyl-hydroxylase domain 2 (PHD-2), downregulation of PHD-2 by small interfering RNA (siRNA) could stabilize HIF-1α and, therefore, upregulate the expression of pro-angiogenic factors as well.

Unintentional cetirizine overdose causing anticholinergic syndrome.

Am J Emerg Med 2022 02 25;52:270.e1-270.e3. Epub 2021 Aug 25.

Cooper University Hospital, Department of Emergency Medicine - 1 Cooper Plaza, Camden, NJ 08103, United States of America; Cooper University Hospital, Department of Toxicology - 1 Cooper Plaza, Camden, NJ 08103, United States of America.

The incidence of anticholinergic syndrome due to second generation antihistamines is infrequently reported. Largely due to their decreased affinity for central nervous system (CNS) receptors, second generation antihistamines are rarely associated with anticholinergic symptoms, though toxicity is still possible particularly when taken in excess. We report a case of a six year old boy who presented with agitation, hallucinations, fixed and dilated pupils, tachycardia, and hyperthermia consistent with anticholinergic toxicity several hours after accidental overdose of a second generation antihistamine, cetirizine.
