Moroccan and French honeys from different geographical areas were classified and characterized by applying a voltammetric electronic tongue (VE-tongue) coupled to analytical methods. The studied parameters include color intensity, free lactonic and total acidity, proteins, phenols, hydroxymethylfurfural content (HMF), sucrose, reducing and total sugars. The geographical classification of different honeys was developed through three-pattern recognition techniques: principal component analysis (PCA), support vector machines (SVMs) and hierarchical cluster analysis (HCA)...

INTRODUCTION: Cancer of the oral cavity (Oral cancer) is the 11th most common malignancy in the world. Despite the general global trend of a slight decrease in the incidence of oral cancer, tongue cancer incidence is increasing. The incidence and mortality caused by this tumor show variability according to the geographic location in which it is diagnosed. However, in the last decade an increase was observed in the percentage of young patients, especially patients with tongue cancer. The main risk factors of head and neck cancer worldwide are smoking and alcohol, as well as DNA oncogenic viruses and habits, such as betel nut...

Sarcoidosis is a multisystem granulomatous disease which frequently affects young adults. Because of its rarity, the exact incidence and prevalence of childhood sarcoidosis is not known. It mostly affects children of older age group i.e., 13-15 years. Early onset sarcoidosis (<5 years) is characterized by a triad of arthritis, uveitis and rash. Late onset sarcoidosis present with a multisystem disease similar to adults, with frequent pulmonary infiltrations and lymphadenopathy. Herein, we report a case of early-onset childhood sarcoidosis in a four-year-old female along with uncommon clinical features like cutaneous ulceration, onycholysis and geographical tongue and its rarity in the literature...

Background and Aims: The outbreeding floral polymorphism heterostyly frequently breaks down, resulting in the evolution of self-fertilization as a result of homostyle formation. Here, the loss of floral polymorphism in distylous Primula oreodoxa, a sub-alpine species restricted to western Sichuan, China, was examined by investigating the ecological correlates and genetic consequences of mating system transitions. Several key questions were addressed. (1) What are the frequencies, geographical distribution and reproductive characteristics of floral morphs in distylous and homostylous populations? (2) Does increased elevation influence pollinator service and the likelihood of inbreeding in populations? (3) How often has homostyly originated and what are the consequences of the breakdown of distyly for the amounts and distribution of genetic diversity in populations? Methods: Fourteen populations throughout the range of P...

Psoriasis is a chronic inflammatory immune-mediated disorder associated and often coexisting with many other immune-related clinical conditions including those affecting the gastrointestinal tract. Data obtained from the reviewed literature suggest an association between psoriasis and pathologies of the oral cavity, both psoriasis-specific lesions, as well as non-specific, such as geographic tongue or fissured tongue. These findings show the importance of thorough examination of oral mucosa in psoriatic patients...

Geographic tongue (GT) is an oral mucosal lesion that affects the tongue. The association between GT and the bacterial colonization profiles of the tongue is not clear. Lingual swabs were collected from lesion sites and healthy sites of 35 patients with GT (19 males and 16 females; Mage = 54.3 ± 16.1 years) and 22 controls (12 males and 10 females; Mage = 56.3 ± 15.8 years). Bacterial DNA was extracted and sequenced by next-generation sequencing. At the phylum level, Fusobacteria were significantly less abundant, while Spirochaetes were significantly more abundant in GT patients compared to controls...

Conservation biology can profit greatly from incorporating a phylogenetic perspective into analyses of patterns and drivers of species extinction risk. We applied such an approach to analyse patterns of bumblebee (Bombus) decline. We assembled a database representing approximately 43% of the circa 260 globally known species, which included species extinction risk assessments following the International Union fo Conservation of Nature Red List categories and criteria, and information on species traits presumably associated with bumblebee decline...

Head and neck squamous cell carcinoma (HNSCC) is typically regarded as a disease of elderly people. However, increasing numbers of patients worldwide with HNSCC at younger age (defined as <45 years old) have been reported in recent years. To assess geographical variations and trends worldwide in incidence of oral and oropharyngeal cancer in young patients, a systematic review was conducted in PubMed and Google scholar databases from 1975 to June 2016. Seventy-eight studies were selected for further study...

BACKGROUND: Adolescence is a period of transition to adulthood. Little is known about oral mucosal lesions (OMLs) in teenagers, in which the emergence of new habits, unfamiliar to children, could affect the type of lesions. The aim of this study was to evaluate the distribution of oral mucosal lesions (OMLs) in a wide sample of adolescents. METHODS: A retrospective cross-sectional study was carried out examining all medical records of adolescents (aged 13-18 years) treated at the Dental Clinic of the University of Brescia (Italy) in the period from 2008 to 2014...

"Geographic atrophy" is a concise term that has been firmly established for the description of the end-stage manifestation of nonexudative age-related macular degeneration (AMD). "Geographic lesions" resembling sharply demarcated continents on a map have been originally described in the German literature in 1854 (landkartenartiger/inselförmiger Zungenfratt) for a manifestation later called "geographic tongue" in English. In 1970, Gass was the first to describe "geographic areas of atrophy" in "senile macular choroidal degeneration...

Geographic tongue (GT) is a benign inflammatory disorder of unknown etiology. Epidemiology and histopathology in previous studies found that generalized pustular psoriasis (GPP) is a factor associated with GT, but the molecular mechanism remains obscure. To investigate the mechanism of GT, with and without GPP, three cohorts were recruited to conduct genotyping of IL36RN, which is the causative gene of GPP. In a family spanning three generations and diagnosed with only GT ("GT alone"), GT was caused by the c...

In this study we developed a genome-based method for detecting Staphylococcus aureus subtypes from metagenome shotgun sequence data. We used a binomial mixture model and the coverage counts at >100,000 known S. aureus SNP (single nucleotide polymorphism) sites derived from prior comparative genomic analysis to estimate the proportion of 40 subtypes in metagenome samples. We were able to obtain >87% sensitivity and >94% specificity at 0.025X coverage for S. aureus. We found that 321 and 149 metagenome samples from the Human Microbiome Project and metaSUB analysis of the New York City subway, respectively, contained S...
