J Pharm Biomed Anal 2019 Apr 8;171:212-217. Epub 2019 Apr 8.

Department of Pharmacy, The First Affiliated Hospital of Harbin Medical University, Harbin, China. Electronic address:

Arsenic trioxide [AsO, arsenite (As) in solution] has been applied successfully for the treatment of acute promyelocytic leukemia (APL). The arsenic speciation analysis of urine is critical to reveal the metabolic mechanism and the relationship between arsenic species and the clinical response. To characterize the arsenic species in urine, a simple and robust HPLC-HG-AFS method was developed and validated to quantify the levels of arsenic species [As and its metabolites, monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), and arsenate (As)] in urine samples from 66 patients with APL.

Carbonic anhydrase activity as a potential biomarker for acute exposure to copper in corals.

Chemosphere 2019 Apr 15;227:598-605. Epub 2019 Apr 15.

Instituto Coral Vivo, Rua dos Coqueiros, Parque Yaya, Santa Cruz Cabrália, BA, 45807-000, Brazil; Instituto de Ciências Biológicas, Universidade Federal do Rio Grande, Av. Itália, Km 8, Rio Grande, RS, 96203-900, Brazil. Electronic address:

Coral reefs are subjected to climate change and are severely impacted by human activities, with copper (Cu) being a relevant physiological stressor for corals at local scale. The ecological relevance of parameters measured at biochemical or cellular level is now considered an extremely important feature in environmental studies, and can be used as early warning signs of environmental degradation. In this context, the effects of acute exposure (96 h) to Cu were assessed on the maximum photochemical efficiency of zooxanthellae (Fv/Fm) and on the activity of key enzymes [carbonic anhydrase (CA) and Ca-ATPase] involved in coral physiology using the scleractinian coral Mussismilia harttii as a biological model.

Expressional regulation of gonadotropin receptor genes and androgen receptor genes in the eel testis.

Gen Comp Endocrinol 2019 Apr 19. Epub 2019 Apr 19.

Department of Zoology, University of Otago, P.O. Box 56, Dunedin 9054, New Zealand.

Receptors for follicle-stimulating hormone (Fshr), luteinizing hormone (Lhcgr1 and Lhcgr2) and androgens (Ara and Arb) transduce the hormonal signals that co-ordinate coordinate spermatogenesis, but the factors that regulate the abundance of these transducers in fish testes remain little-understood. To mend this paucity of information, we first determined changes in transcript abundance for these receptors (fshr, lhcgr1, ara and arb) during spermatogenesis induced by human chorionic gonadotropin (hCG) injection in the eel, Anguilla australis. We related our findings to testicular production of the fish androgen, 11-ketotestosterone (11-KT), and to the levels of the transcripts encoding steroidogenic acute regulatory protein (star) and 11β-hydroxylase (cyp11b), and subsequently evaluated the effects of hCG or 11-KT on mRNA levels of these target genes in vitro.

Secondary Bleeding During Acute Experimental Intracerebral Hemorrhage.

Stroke 2019 May;50(5):1210-1215

From the Neurovascular Research Laboratory, Department of Radiology (F.S., M.B., T.Q., I.T., P.F., C.A.), Massachusetts General Hospital, Harvard Medical School, Charlestown.

Background and Purpose- Mechanisms contributing to acute hematoma growth in intracerebral hemorrhage are not well understood. Neuropathological studies suggest that the initial hematoma may create mass effect that can tear vessels in the vicinity by shearing, causing further bleeding and hematoma growth. Methods- To test this in mice, we simulated initial intracerebral hemorrhage by intrastriatal injection of a liquid polymer that coagulates upon contact with tissue and measured the presence and volume of bleeding secondary to the mass effect using Hemoglobin ELISA 15 minutes after injection.

ERASER.

Stroke 2019 May;50(5):1275-1278

From the Department of Neuroradiology (J.F., M.B., H.K., S.G.), University Hospital Hamburg-Eppendorf, Germany.

Background and Purpose- Using a novel study design with virtual comparators based on predictive modeling, we investigated whether next-generation mechanical thrombectomy devices improve outcomes in patients with ischemic stroke. We hypothesized that this new study design shows that a next-generation mechanical thrombectomy system is superior to intravenous tPA (tissue-type plasminogen activator) therapy (IVT) alone. Methods- ERASER (Eric Acute Stroke Recanalization) was an investigator-initiated, prospective, multicenter, single-arm (virtual 2-arm) study that evaluated the effectiveness of a new recanalization device together with a specific intermediate catheter (Embolus Retriever with Interlinked Cages/SOFIA, Microvention) in stroke patients with internal carotid artery or middle cerebral artery occlusions.

Acute Stroke With Large Ischemic Core Treated by Thrombectomy.

Stroke 2019 May;50(5):1164-1171

Department of Neurology, Foch Hospital, Versailles Saint-Quentin en Yvelines University, Suresnes, France (B.L.).

Background and Purpose- Acute stroke patients with a large ischemic core may still benefit from mechanical thrombectomy (MT), but the predictors of clinical outcome are not well known after MT. We investigated the clinical and imaging factors associated with good outcome and mortality at 90 days in acute stroke patients with a large baseline ischemic core treated with MT. Methods- Data from the multicentric prospective ETIS (Endovascular Treatment in Ischemic Stroke) registry of consecutive acute ischemic stroke patients treated with MT from January 1, 2012, to August 31, 2016, were retrospectively analyzed.

Arteriopathy Influences Pediatric Ischemic Stroke Presentation, but Sickle Cell Disease Influences Stroke Management.

Stroke 2019 May;50(5):1089-1094

Departments of Pediatrics, Neurology and Neurotherapeutics, University of Texas Southwestern Medical Center at Dallas and Children's Health Dallas (M.M.D.).

Background and Purpose- Sickle cell disease (SCD) and arteriopathy are pediatric stroke risk factors that are not mutually exclusive. The relative contributions of sickled red blood cells and arteriopathy to stroke risk are unknown, resulting in unclear guidelines for primary and secondary stroke prevention when both risk factors are present. We hypothesized that despite similarities in clinical presentation and radiographic appearance of arteriopathies, stroke evaluation and management differ in children with SCD compared with those without SCD.

Differential response of human blood leukocytes to brushite, monetite, and calcium polyphosphate biomaterials.

J Biomed Mater Res B Appl Biomater 2019 Apr 22. Epub 2019 Apr 22.

Faculty of Dentistry, University of Toronto, Toronto, Ontario, Canada.

Calcium phosphate-based biomaterials are extensively used for bone replacement and regeneration in orthopedic, dental, and maxillofacial surgical applications. The injury induced by surgical implantation of bone replacement graft materials initiates a cascade of host responses, starting with blood-biomaterial contact, protein adsorption on the material surface, blood coagulation, and leukocyte responses. During the initial acute inflammatory response, polymorphonuclear neutrophils (PMNs) and monocytes, abundant circulating leukocytes of the myeloid lineage, are recruited to the site of inflammation.

Melatonin Stabilizes Rupture-Prone Vulnerable Plaques via Regulating Macrophage Polarization in a Nuclear Circadian Receptor RORα-Dependent Manner.

J Pineal Res 2019 Apr 22:e12581. Epub 2019 Apr 22.

State Key Laboratory for Oncogenes and Related Genes, Division of Cardiology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai Cancer Institute, Shanghai, China.

Rupture of vulnerable plaques is the main trigger of acute cardio-cerebral vascular events, but mechanisms responsible for transforming a stable atherosclerotic into a vulnerable plaque remain largely unknown. Melatonin, an indoleamine hormone secreted by the pineal gland, plays pleiotropic roles in the cardiovascular system; however, the effect of melatonin on vulnerable plaque rupture and its underlying mechanisms remain unknown. Here, we generated a rupture-prone vulnerable carotid plaque model induced by endogenous renovascular hypertension combined with low shear stress in hypercholesterolemic ApoE mice. Read More
