Argon plasma coagulation in the treatment of post-radiotherapy rectal bleeding
2012
Introduction: Chronic radiation proctitis is often associated to radiotherapy for treatment of pelvic cancer. The most common side effect of this pathological condition is rectal bleeding but despite the great number of clinical approaches and techniques that have been employed no consensus for the management of it is available. Although prospective randomized trials about hemorrhagic radiation proctitis are still lacking, endoscopic approach delivering an Argon Plasma Coagulation (APC) seems to be a successful and available option. Patients and Methods: Sixteen patients suffering from post-radiotherapy rectal bleeding were followed. In the nine cases presenting a rectum ulcerative colitis …
Evaluation of the anti-inflammatory and analgesic action of hydrogel in thyroid orbitopathy.
2011
Purpose: To evaluate the analgesic efficacy of applying on the eyelid surface sterile hydrogel dressings containing substances such as pineapple extract which has anti-inflammatory and antioedema properties, and 18 beta-glycyrrhetinic acid. Design: Randomized prospective clinical trial. Methods: 50 patients (16 males and 34 females) affected with thyroid-associated orbitopathy in acute phase equally distributed in two groups. The level of patient satisfaction of the treatment was measured by answering a questionnaire before and after the treatment phase. Results: While 24 patients of study group reported an reduction in the pain only 2 of control group did. In the study group questionnaire’…
A national multicentre study on severe paediatric recurrent idiopathic pericarditis treated with IL-1 blockers: appropriateness of the standard of ca…
2020
Recurrent pericarditis (RP) is a rare cause of morbidity in children. Non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoids and colchicine are the standard of care in adults. Recently, anakinra has been proven to be effective in patients with steroid-dependence and colchicine resistance.
Dihydroisocoumarins, Naphthalenes, and Further Polyketides from Aloe vera and A. plicatilis: Isolation, Identification and Their 5-LOX/COX-1 Inhibiti…
2021
The present study aims at the isolation and identification of diverse phenolic polyketides from Aloe vera (L.) Burm.f. and Aloe plicatilis (L.) Miller and includes their 5-LOX/COX-1 inhibiting potency. After initial Sephadex-LH20 gel filtration and combined silica gel 60- and RP18-CC, three dihydroisocoumarins (nonaketides), four 5-methyl-8-C-glucosylchromones (heptaketides) from A. vera, and two hexaketide-naphthalenes from A. plicatilis have been isolated by means of HSCCC. The structures of all polyketides were elucidated by ESI-MS and 2D 1H/13C-NMR (HMQC, HMBC) techniques. The analytical/preparative separation of 3R-feralolide, 3′-O-β-d-glucopyranosyl- and the new 6-O-β-d-glucopyranosyl…
Strategies to Target ADAM17 in Disease: From Its Discovery to the iRhom Revolution
2021
For decades, disintegrin and metalloproteinase 17 (ADAM17) has been the object of deep investigation. Since its discovery as the tumor necrosis factor convertase, it has been considered a major drug target, especially in the context of inflammatory diseases and cancer. Nevertheless, the development of drugs targeting ADAM17 has been harder than expected. This has generally been due to its multifunctionality, with over 80 different transmembrane proteins other than tumor necrosis factor α (TNF) being released by ADAM17, and its structural similarity to other metalloproteinases. This review provides an overview of the different roles of ADAM17 in disease and the effects of its ablation in a n…
Phytochemical composition, anti-inflammatory and antitumour activities of four Teucrium essential oils from Greece
2009
Abstract The essential oils of four Teucrium species were studied and 150 components, in all, were identified. All oils were rich in sesquiterpenes (50.1–55.8%). Spathulenol and δ-cadinene were the main compounds of Teucrium brevifolium oil; caryophyllene and 4-vinyl guaiacol predominated in Teucrium flavum . Carvacrol and caryophyllene oxide predominated in Teucrium montbretii ssp. heliotropiifolium , while carvacrol and caryophyllene were the most abundant components in Teucrium polium ssp. capitatum . The oil which most effectively inhibited LPS-induced NO production in macrophage cell line RAW 264.7 was that from T. brevifolium (IC 50 = 7.1 μg/ml), followed by T. montbretii ssp. heliot…
Design of an Herbal Preparation Composed by a Combination of Ruscus aculeatus L. and Vitis vinifera L. Extracts, Magnolol and Diosmetin to Address Ch…
2023
Chronic venous disease (CVD) is an often underestimated inflammatory pathological condition that can have a serious impact on quality of life. Many therapies have been proposed to deal with CVD, but unfortunately the symptoms recur with increasing frequency and intensity as soon as treatments are stopped. Previous studies have shown that the common inflammatory transcription factor AP-1 (activator protein-1) and nuclear factor kappa-activated B-cell light chain enhancer (NF-kB) play key roles in the initiation and progression of this vascular dysfunction. The aim of this research was to develop a herbal product that acts simultaneously on different aspects of CVD-related inflammation. Based…
Cyclo-oxygenase isoenzymes. How recent findings affect thinking about nonsteroidal anti-inflammatory drugs
1997
International audience; The discovery of at least 2 cyclo-oxygenase (COX) isoenzymes, referred to as COX-1 and COX-2, has updated our knowledge of nonsteroidal anti-inflammatory drugs (NSAIDs). This has lead investigators to reconsider what can be awaited from this class of drugs. The 2 COX isoenzymes share structural and enzymatic similarities, but are specifically regulated at the molecular level and may be distinguished apart in their functions, although some physiological overlap between them does occur. The major goal in developing selective COX inhibitors is to improve NSAID tolerability. Classic NSAIDs preferentially inhibit COX-1 in vitro, but it appears hazardous to judge their gas…
Antioxidative effects of cactus pear (Opuntia ficus indica, L. Mill.) fruits from Sicily and bioavailability of betalain components in healthy humans
2009
Aerobic life is characterised by a steady formation of pro-oxidants, which is approximately balanced by antioxidant defense systems. When cell’s capacity to protect itself fails, oxidative stress occurs. Because of bioactive components vegetables are now considered helpful in preventing chronic pathologies in which oxidative damage is an important etiologic factor. Cactus pear (Opuntia ficus-indica) fruit contains substantial amounts of vitamin C, biothiols, and taurine, and redox-active betalain pigments. It has been shown that a short-term supplementation (500 g fruit pulp daily, 2 wk) positively affected the body’s redox balance, decreased lipid oxidation, and improved antioxidant status…
Topical Anti-Inflammatory Lignans from Haplophyllum hispanicum Haplophyllum hispanicum
1996
The present paper reports the results of the methanol extract of Haplophyllum hispanicum Spach on single or repeated local 12-O-tetradecanoylphorbol acetate (TPA) administration and in the oxazolone-induced contact-delayed hypersensitivity mouse ear edemas. Two topical anti-inflammatory aryl naphthalide lignans were isolated from the active fractions of the methanol extract. They were identified by spectroscopic methods, including 13C NMR and heteronuclear multiple bond correlation (HMBC), as diphyllin acetyl apioside and tuberculatin. The former was the most active on acute TPA edema with a ID50 of 0.27 μmol/ear
