The genetic association of the methylenetetrahydrofolate reductase gene (MTHFR) 677C>T polymorphism with methotrexate (MTX)-associated toxicity has been evaluated and conflicting results have been reported. The substantial heterogeneity of the studied population was suggested to be a possible explanation because ethnicity, MTX dose, coadministered chemotherapeutic agents, and folinate rescue dosage regimen could alter the MTX toxicity profile. The patient population was homogenized by limiting the cancer type to primary central nervous system lymphoma and chemotherapy protocol to a high-dose MTX monotherapy regimen...

Evidence generated through research studies has guided programmatic actions and fine-tuned strategies for the Global Polio Eradication Initiative (GPEI). However, many gaps still persist in the understanding of a risk-free implementation of the polio endgame. Immediate concerns relate to the introduction of inactivated polio vaccine (IPV) and switch from trivalent oral polio vaccine (tOPV) to bivalent oral polio vaccine (bOPV) in routine immunization schedule. A comprehensive understanding of mucosal immunity in populations and best response options against circulating vaccine derived poliovirus (cVDPV) outbreaks in post tOPV-bOPV switch is essential to mitigate the risks of wild and vaccine-derived poliovirus importations and emergence of cVDPVs in polio-free countries...

Twenty-one, 25-day-old, artificially reared, coccidia-free goslings (Anser cygnoides var. domestica) were inoculated orally with 0.5 × 10(4), 1 × 10(4), or 100 × 10(4) sporulated oocysts of Eimeria anseris and sacrificed at intervals from 24 to 216 h post-inoculation (HPI). Nine uninfected goslings served as negative controls. Parts of the visceral organs from goslings, including the intestines, kidneys, and liver, were fixed, sectioned, and observed microscopically. The results revealed that two generations of meronts occurred in the life cycle of E...

Mucoadhesive drug delivery systems stick to mucosal tissues and prolong the local retention time of drugs. Since the colon is covered by a mucosal layer, mucoadhesive rectal formulations may improve treatment of such diseases as hypertension or colon cancer. Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic inflammation of the colonic mucosa. It is commonly treated with sulfasalazine (SSZ), which is metabolized by the intestinal flora into the therapeutic 5-aminosalicylic acid (5-ASA) and a toxic by-product sulfapyridine (SP)...

Radiotherapy (RT) is the normative therapeutic treatment for primary nasopharyngeal carcinoma (NPC). Single nucleotide polymorphisms (SNPs) of genes in Wnt/β-catenin pathway are correlated to the development, prognosis, and treatment benefit of various cancers. However, it has not been established whether SNPs of Wnt/β-catenin pathway are associated with nasopharyngeal tumorigenesis and the efficacy of RT in NPC patients. Therefore, in this study, we aimed to investigate the nine potentially functional SNPs of four genes in the Wnt/β-catenin pathway and genotyped these in 188 NPC patients treated with RT...

BACKGROUND: Von Willebrand disease (VWD) is not uncommon in Taiwan. In type 2 or type 3 VWD hemorrhagic symptoms are severer and laboratory data relatively more distinctive. De novo mutation and somatic mosaicism of type 2 VWD gene were rarely reported. Therefore clinical, laboratory and genetic studies of only type 2A, 2B and 2M VWD will be presented and issues of de novo mutation and somatic mosaicism will be explored. METHODS: Fifty-four patients belonging to 23 unrelated families from all around the country in whom type 2 VWD exclusive of type 2N has been diagnosed not only by clinical and routine laboratory studies but also by genetic confirmation during 1990-2015 were investigated...

Oral squamous cell carcinoma (OSCC) is extremely rare in patients younger than 20 years of age. We present here a case of OSCC of the maxillary alveolar ridge in an otherwise healthy 8-year-old patient. The clinicohistologic presentation was not typical for mucosal SCC, and the possibility of an intrabony origin from the odontogenic epithelium was considered. The patient was treated with surgical resection, and treatment decisions were made with consideration of the need for eradication of tumor as well as tissue preservation to allow normal growth and development...

Interleukin-17 (IL-17) is a multifaceted cytokine with diverse roles both in immune-protection and also immunopathology. IL-17 has a well-recognized role in immune surveillance at mucosal and barrier surfaces (Miossec & Kolls, 2012, Song et al., 2016) but also has been increasingly implicated as a driver of immunopathology in settings of autoimmunity and chronic inflammation (Gaffen et al., 2014).

By using next-generation sequencing targeted to MitoExome including the entire mtDNA and exons of 1033 genes encoding the mitochondrial proteome, we described here a novel m.11240C>T mutation in the mitochondrial ND4 gene from a patient with Leigh syndrome. High mutant loads of m.11240C>T were detected in blood, urinary epithelium, oral mucosal epithelium cells, and skin fibroblasts of the patient. Decreased mitochondrial complex I activity was found in transmitochondrial cybrids containing the m.11240C>T mutation with biochemical analysis...

Infection-associated inflammatory stress during pregnancy is the most common cause of fetal growth restriction and/or miscarriage. Treatment strategies for protection of at-risk mothers are limited to a narrow range of vaccines, which do not cover the bulk of the common pathogens most frequently encountered. Using mouse models, we demonstrate that oral treatment during pregnancy with a microbial-derived immunomodulator (OM85), currently used clinically for attenuation of infection-associated airway inflammatory symptoms in infants-adults, markedly reduces risk for fetal loss/growth restriction resulting from maternal challenge with bacterial lipopolysaccharide or influenza...

Infection with the parasite Toxoplasma gondii causes serious public health problems and is of great economic importance worldwide. No vaccine is currently available, so the design of efficient vaccine strategies is still a topical question. In this study, we evaluated the immunoprophylactic potential of a T. gondii virulence factor, the rhoptry kinase ROP18, in a mouse model of chronic toxoplasmosis: first using a recombinant protein produced in Schneider insect cells adjuvanted with poly I:C emulsified in Montanide SV71 by a parenteral route or adjuvanted with cholera toxin by the nasal route and second using a DNA plasmid encoding ROP18 adjuvanted with GM-CSF ± IL-12 DNA...

BACKGROUND: Recurrent aphthous stomatitis (RAS) is the most common painful ulcers of oral mucosal which can cause many sufferings. Treatment of RAS often includes administration of corticosteroids, analgesics and regulators of the immune system. However, considering the side effects of these medications, even their topical application must be done with caution. Alum is used in traditional medicine for treatment of oral ulcers without significant side effect. This study sought to assess the effect of topical application of alum on aphthous ulcers...

Anecdotal and scientific evidence suggests that Cannabis use may be beneficial in inflammatory bowel disease (IBD) patients. Here, we have investigated the effect of a standardized Cannabis sativa extract with high content of cannabidiol (CBD), here named CBD BDS for "CBD botanical drug substance," on mucosal inflammation and hypermotility in mouse models of intestinal inflammation. Colitis was induced in mice by intracolonic administration of dinitrobenzenesulfonic acid (DNBS). Motility was evaluated in the experimental model of intestinal hypermotility induced by irritant croton oil...
