Objective: The study aimed to provide an update on the evaluation, diagnosis, and treatment of onychomycosis. Methods: A PubMed search was completed in Clinical Queries using the key term “onychomycosis”. The search was conducted in May 2019. The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews published within the past 20 years. The search was restricted to English literature. Patents were searched using the key term “onychomycosis” in www.freepatentsonline.com. Results: Onychomycosis is a fungal infection of the nail unit. Approximately 90% of toenail and 75% of fingernail onychomycosis are caused by dermatophytes, notably Trichophyton mentagrophytes and Trichophyton rubrum. Clinical manifestations include discoloration of the nail, subungual hyperkeratosis, onycholysis, and onychauxis. The diagnosis can be confirmed by direct microscopic examination with a potassium hydroxide wet-mount preparation, histopathologic examination of the trimmed affected nail plate with a periodic-acid-Schiff stain, fungal culture, or polymerase chain reaction assays. Laboratory confirmation of onychomycosis before beginning a treatment regimen should be considered. Currently, oral terbinafine is the treatment of choice, followed by oral itraconazole. In general, topical monotherapy can be considered for mild to moderate onychomycosis and is a therapeutic option when oral antifungal agents are contraindicated or cannot be tolerated. Recent patents related to the management of onychomycosis are also discussed. Conclusion: Oral antifungal therapies are effective, but significant adverse effects limit their use.Although topical antifungal therapies have minimal adverse events, they are less effective than oral antifungal therapies, due to poor nail penetration. Therefore, there is a need for exploring more effective and/or alternative treatment modalities for the treatment of onychomycosis which are safer and more effective.","PeriodicalId":13680,"journal":{"name":"Inflammation & allergy drug targets","volume":"66 1","pages":"32 - 45"},"PeriodicalIF":0.0,"publicationDate":"2019-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87507191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NO produced by iNOS has been found to contribute to liver injury. Treatment of primary cultures of rat hepatocytes with the proinflammatory cytokine interleukin (IL)-1β stimulated iNOS expression and NO production. Experiments with this in vitro hepatocyte model of liver injury and with in vivo animal models of liver injury have demonstrated that drugs showing a liver-protective effect in vivo also inhibited the induction of iNOS expression and NO production both in vivo and in vitro. Thus, in this in vitro hepatocyte model, the prevention of iNOS expression and NO production are considered indicators of liver protection.\u0000\u0000\u0000RESULTS/CONCLUSION\u0000This review describes a simple in vitro liver injury model, consisting of IL-1β-stimulated cultured hepatocytes, and methods used to analyze the mechanisms of action of drugs that inhibit iNOS expression.

However, apart from certain specific vaccine strains and complications (such as the swine flu vaccine and Guillain-Barré syndrome in 1976, thrombocytopenia and the Measles-Mumps-Rubella vaccine), this role has not been established. In spite of this, many isolated cases or series of cases of arthritis, vasculitis, and central or peripheral nervous system symptoms following vaccination have been reported. These cases tend to be very infrequent and usually only the shortterm outcomes are described. This paper will examine the arguments for and against the relationship between vaccines and AID, bearing in mind that no association between the two has been clearly identified up to now. The role of adjuvants in vaccines has been described by other teams and in a more general syndrome (Autoimmune/Autoinflammatory Syndrome Induced by Adjuvants). Thus, cases of AID triggered by vaccines are highly rare and raise questions about the interaction between vaccines and/or their adjuvants and the genetic context of autoimmune disease. These observations should therefore not undermine the benefits of vaccination.","PeriodicalId":13680,"journal":{"name":"Inflammation & allergy drug targets","volume":"21 1","pages":"94-8"},"PeriodicalIF":0.0,"publicationDate":"2015-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78764198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have previously described a significant diminution in the GABAergic regulation of glutamate release from synaptosomes of EAE rats isolated during the acute stage of the disease. In order to explore the possible metabolic pathways responsible for this alteration, in this work we evaluate the direct effect of different GABAergic agonists on the glutamate release and concomitant synapsin I phosphorylation in synaptosomes from the frontal cortex of control and EAE animals. The results show that GABA as well as the GABA receptor agonists Muscimol (GABAA agonist) and Baclofen (GABAB agonist) caused a decrease in glutamate release in control rats paralleled by a similar reduction in synapsin I phosphorylation. Meanwhile synaptosomes from EAE animals are responsive only to Baclofen with respect to nontreated EAE synaptosomes, since glutamate release from the synaptosomes treated with Muscimol was similar to that observed in EAE rat synaptosomes which was already reduced as consequence of the disease. In the case of the benzodiazepines Diazepam and Clonazepam (GABAA allosteric agonists), both of them induced a reduction in glutamate release in synaptosomes from the CFA rats, effect that was only observed in synaptosomes of EAE rats treated with Clonazepam. In all cases both benzodiazepines showed a higher effect on synapsin I phosphorylation than in glutamate release. These results indicate that the extent of GABAergic modulation of presynaptic terminals depends on the type of agonist employed and this regulation is altered in the frontal cortex during the acute phase of EAE with respect to control animals.","PeriodicalId":13680,"journal":{"name":"Inflammation & allergy drug targets","volume":"4 6 1","pages":"105-10"},"PeriodicalIF":0.0,"publicationDate":"2015-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84262853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five isolated flavonoids were investigated for their antiinflammatory and antimicrobial activities. Eriodictyol demonstrated maximum anti-inflammatory activity (53.09%) at 30.0 mg/kg dose on 6(th) h and similarly, it inhibited the CFA-induced arthritis swelling (41.84%) with 30.0 mg/kg dose on 8(th) day respectively. As per disc diffusion and microdilution methods used for antimicrobial activity determination, the pinocembrin was found to be most active against Staphylococcus aureus (IZ=27±0.7 mm, 08 μg/ml dose) and Candida albicans (IZ=17±0.9 mm; 12 μg/ml dose). These investigated results revealed that the eriodictyol and pinocembrin showed significant anti-inflammatory and antimicrobial activities.

A few studies have now indicated that some patients might tolerate mercaptopurine (6-MP) for azathioprine. In this paper, we review the literature, and reappraise our own data against the published figures. The data which form the basis for this study span over all visit reports that were released between January 2008 and December 2011 in a primary care Hospital, in Turin, Italy. For the aim of this study we searched our own database and the MedLine using the key-words \"azathioprine\", \"mercaptopurine\", \"thiopurine\", \"inflammatory bowel disease\", \"Crohn's disease\", \"ulcerative colitis\". We retrieved 85 azathioprine prescriptions for 42 UC, 37 CD, and 6 miscellaneous patients. There were 10 episodes of gastric intolerance to azathioprine, which were switched to 6-MP: 6 out of 10 (60%) responded and tolerated the switch drug in a median follow-up of 66 months. Female gender prevailed (p=0.038) in the azathioprine intolerant subset.

Our results show that H2S is produced by the activity of CSE in these cells. To investigate the role of common signalling pathway in biosynthesis of CSE in human primary macrophages, specific inhibitors were used to block NF-κB, ERK, p38 and JNK. Inhibition of NF-κB, ERK significantly reduced levels of CSE gene and protein expression in these cells but inhibition of JNK and p38 did not have an inhibitory effect on the expression of CSE gene in macrophages. Inhibition of NF-κB and ERK prevented the effect of LPS on H2S synthesizing activity in human primary macrophages.

Uranium is able to damage the DNA by generation of free radicals and acting as a catalyst in the Fenton reactions causing oxidative stress. In fact, reproductive system contains high amount of polyunsaturated fatty acids, and therefore it is highly vulnerable to reactive oxygen species (ROS) and sensitive to uranium toxicity. Toxic effects of uranium are generally reported through different mechanisms of action including inflammation, degeneration of testis, vacuolization of Leydig cells, spermatocytes necrosis, and oocyte dysmorphism.
