Neuroprotective effects of a novel carnosine-hydrazide derivative on hippocampal CA1 damage after transient cerebral ischemia.

Eur J Med Chem 2018 Nov 28;163:207-214. Epub 2018 Nov 28.

Department of Neurosurgery, Kurume University, School of Medicine, Fukuoka, Japan. Electronic address:

Ischemia-reperfusion injuries produce reactive oxygen species that promote the peroxide lipid oxidation process resulting in the production of an endogenic lipid peroxide, 4-hydroxy-trans-2-nonenal (4-HNE), a highly cytotoxic aldehyde that induces cell death. We synthesized a novel 4-HNE scavenger - a carnosine-hydrazide derivative, l-carnosine hydrazide (CNN) - and examined its neuroprotective effect in a model of transient ischemia. PC-12 cells were pre-incubated with various doses (0-50 mmol/L) of CNN for 30 min, followed by incubation with 4-HNE (250 μM). Read More

Radical carbofluorination of alkenes with arylhydrazines and Selectfluor: Additives, mechanistic pathways and polar effects.

Chemistry 2018 Dec 5. Epub 2018 Dec 5.

Friedrich-Alexander-Universitat Erlangen-Nurnberg, Chemistry and Pharmacy, Schuhstrasse 19, 91052, Erlangen, GERMANY.

Radical carbofluorination reactions starting from arylhydrazines and non-activated alkenes, in which the C-F bond is formed through the use of Selectfluor, can be improved through the addition of anisole. Since direct trapping products could be detected only in trace amounts, anisole does primarily act as a reversible scavenger for the highly reactive ammonium radical dication released from Selectfluor in the C-F bond forming step. As shown for three diverse substitution patterns, the main role of anisole is to prevent, or at least reduce, the undesired addition of the ammonium radical dication to the alkene, which in turn leads to an unfavorable consumption of the arylhydrazine-derived precursors required for carbofluorination.

NAD(P)H quinone oxidoreductase 1 (NQO1) catalyses the two electron reduction of quinones and a wide range of other organic compounds. Its physiological role is believed to be partly the reduction of free radical load in cells and the detoxification of xenobiotics.  It also has non-enzymatic functions stabilising a number of cellular regulators including p53.

Masquelet technique to treat a septic nonunion after nailing of a femoral open fracture.

Injury 2018 Nov 22. Epub 2018 Nov 22.

Orthopaedics and Trauma Unit, Emergency Department, Ospedale Policlinico San Martino, Largo R. Benzi 10-16132, Genoa, Italy.

Septic nonunion is one of the most serious complications after an open fracture because both the infection and the bone defect need to be dealt with. Treatment is always protracted and expensive, and the result is uncertain. In the 1980s, Masquelet first described the technique of the induced membrane and autologous bone grafting to manage critical bone defects. Read More

Sinonasal teratocarcinosarcoma treated with surgery followed by volumetric modulated radiotherapy: a case report with review of literature.

Radiat Oncol J 2018 Dec 7. Epub 2018 Dec 7.

Department of Radiology and Imaging, Rajiv Gandhi Cancer Institute and Research Centre, New Delhi, India.

Surgical excision along with use of postoperative radiotherapy forms an integral management of sinonasal teratocarcinosarcoma (SNTCS). However, given the rarity of the tumor, no standardised guidelines, dose, technique and target delineation exist especially in the era of modern radiation delivery techniques. This is a case of 55-year-old male diagnosed as SNTCS treated with radical ethmoidectomy followed by volumetric modulated radiotherapy, showing good local control and acceptable toxicity profile.

CHU La Pitié-Salpêtrière, Paris, France.

An example of clinical controversy related to EBM. The DCCT study for type 1 diabetes (1993) and UKPDS for type 2 (1998) had demonstrated the benefit of the hypoglycemic treatment with, for 1 point of HbA1c less, 30% less microangiopathy events. The cardiovascular benefit was less obvious, as these studies were performed in patients with primary prevention. Read More

Optimization of Phenolics and Flavonoids Extraction Conditions and Antioxidant Activity of Roasted Yerba-Mate Leaves (Ilex paraguariensis A. St.-Hil., Aquifoliaceae) using Response Surface Methodology.

An Acad Bras Cienc 2014 Jun;86(2):923-934

Departamento de Engenharia de Alimentos, Universidade Estadual de Ponta Grossa, Ponta Grossa, PR, Brasil.

This study focused on maximizing the extraction of total phenolics and flavonoids as well as the antioxidant activity measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay from roasted yerba mate (Ilex paraguariensis) as a function of time (5, 7.5 and 10 min) and temperature of extraction (60, 75 and 90°C). The data were subjected to Response Surface Methodology and the results showed that polynomial equations were significant, did not present lack of fit, and presented adjusted determination coefficients above 98%, proving their suitability for prediction purposes.

Increased plasma levels of the lipoperoxyl radical-derived vitamin E metabolite α-tocopheryl quinone are an early indicator of lipotoxicity in fatty liver subjects.

Free Radic Biol Med 2018 Nov 30. Epub 2018 Nov 30.

Department of Pharmaceutical Science, University of Perugia, Perugia, Italy. Electronic address:

Lipid peroxidation is one of the earliest pathogenic events of non-alcoholic fatty liver disease (NAFLD). In this context, an increased oxidation of the lipoperoxyl radical scavenger α-tocopherol (α-TOH) should occur already in the subclinical phases of the disease to compensate for the increase oxidation of the lipid excess of liver and possibly of other tissues. However, this assumption remains unsupported by direct analytical evidence. Read More

Fabrication of a novel impedimetric biosensor for label free detection of DNA damage induced by doxorubicin.

Int J Biol Macromol 2018 Nov 30. Epub 2018 Nov 30.

Research Center of Oils and Fats, Kermanshah University of Medical Sciences, Kermanshah, Iran. Electronic address:

In this work, a novel impedimetric biosensor has been fabricated for detection of DNA damage induced by doxorubicin (DX). Cytochrome P450 reductase (CPR) is required for electron transfer from nicotinamide adenine dinucleotide phosphate (NADPH) to cytochrome P450 (CP450) which causes DX to undergo a one-electron reduction of the p-quinone residue to form the semiquinone radical resulting in the generation of free hydroxyl radical which causes DNA damage. After modification of bare glassy carbon electrode (GCE) with multiwalled carbon nanotubes (MWCNTs) and chitosan (Ch), CPR and CP450 were co-immobilized onto the surface of Ch/MWCNTs/GCE by cross-linking CPR, CP450 and Ch through addition of glutaraldehyde.
