Beta Glucan: Health Benefits in Obesity and Metabolic Syndrome

Despite the lack of international agreement regarding the definition and classification of fiber, there is established evidence on the role of dietary fibers in obesity and metabolic syndrome. Beta glucan (β-glucan) is a soluble fiber readily available from oat and barley grains that has been gaining interest due to its multiple functional and bioactive properties. Its beneficial role in insulin resistance, dyslipidemia, hypertension, and obesity is being continuously documented. The fermentability of β-glucans and their ability to form highly viscous solutions in the human gut may constitute the basis of their health benefits. Consequently, the applicability of β-glucan as a food ingredient is being widely considered with the dual purposes of increasing the fiber content of food products and enhancing their health properties. Therefore, this paper explores the role of β-glucans in the prevention and treatment of characteristics of the metabolic syndrome, their underlying mechanisms of action, and their potential in food applications

Case Report on Leiomyosarcoma of the Vulva: A Rare Pathology

Leiomyosarcoma (LMS) of the vulva is rare. However it is the most common histologic subtype of vulvar sarcoma, accounting for approximately 1% of all vulvar malignancies. [1-8] Whether genetics and epigenetics play a role in pathogenesis is unclear. [1] The tumor is slow-growing with non-specific symptoms, has high metastatic potential, and follows a bimodal age distribution. [1-8] Diagnosis and prognosis are based upon immunohistochemical expression and criteria from early literature. [1,3,5-7] The most common therapeutic approach involves radical vulvectomy with lymph node resection. The value of adjuvant chemotherapy and radiation remains unknown. [1,3,5-8] Our case describes a 46-year-old Caucasian G2P2 female with LMS of the left labia

Superhydrophobic lab-on-chip measures secretome protonation state and provides a personalized risk assessment of sporadic tumour

Secretome of primary cultures is an accessible source of biological markers compared to more complex and less decipherable mixtures such as serum or plasma. The protonation state (PS) of secretome reflects the metabolism of cells and can be used for cancer early detection. Here, we demonstrate a superhydrophobic organic electrochemical device that measures PS in a drop of secretome derived from liquid biopsies. Using data from the sensor and principal component analysis (PCA), we developed algorithms able to efficiently discriminate tumour patients from non-tumour patients. We then validated the results using mass spectrometry and biochemical analysis of samples. For the 36 patients across three independent cohorts, the method identified tumour patients with high sensitivity and identification as high as 100% (no false positives) with declared subjects at-risk, for sporadic cancer onset, by intermediate values of PS. This assay could impact on cancer risk management, individual’s diagnosis and/or help clarify risk in healthy populations

ACTA OTORHINOLARYNGOLOGICA ITALICA

Presentiamo un caso di posizionamento di impianto cocleare in un uomo di 50 anni che, dopo aver subito tre anni prima un intervento per via retrosigmoidea per un neurinoma dellacustico in stadio 1, è stato colpito da ipoacusia improvvisa ipsilaterale sviluppando un intenso acufene. Dopo lattivazione dellimpianto lacufene è sceso da un grado 4 ad un grado 2 secondo il THI. Sono migliorate le capacità di localizzazione. Lascolto nel rumore (S/R + 7 dB) con il segnale proveniente dal lato operato è migliorato da 38 a 100%. Abbiamo inoltre verificato un significativo incremento dei punteggi relativi a spazialità e linguaggio del questionario Speech, spatial and qualities of sounds. In conclusione limpianto cocleare è una soluzione praticabile ed efficace in caso di insorgenza di ipoacusia ritardata dopo chirurgia conservativa del neurinoma dellacustico

Design and hygiene issues in sports facilities. A pilot study which investigates fitness centres by using a multidisciplinary tool

Introduction. In recent years there has been a considerable increase in general public\u27s awareness of the benefits of physical activity on health, and the number of people becoming physically active has risen. Being gyms the main indoor environment for practicing physical activity, the growth of their attendance has increased the importance of these places.Methods. A multidisciplinary team has developed an assessment tool for hygiene and safety of these areas that evaluates different components (location, dimension, maintenance, etc.). Each section consists of a series of questions that evaluators and facility managers must answer.Discussion. The tool was tested on a sample of case studies analyzing several critical issues that might affect the quality of spaces and users’ health.Conclusions. The observed critical points will allow the future implementation of the instrument. Several design and management considerations also were highlighted, in order to improve the hygiene and health aspects of gyms.Keywords. Design and Management strategies; Fitness centers; Evaluation tool; Indoor Environment; Multidisciplinary approach

Temperature-dependent development, cold tolerance, and potential distribution of cricotopus lebetis (Diptera: Chironomidae), a tip miner of hydrilla verticillata (Hydrocharitaceae)

© The Author 2014. Published by Oxford University Press on behalf of the Entomological Society of America. A chironomid midge, Cricotopus lebetis (Sublette) (Diptera: Chironomidae), was discovered attacking the apical meristems of Hydrilla verticillata (L.f. Royle) in Crystal River, Citrus Co., Florida in 1992. The larvae mine the stems of H. verticillata and cause basal branching and stunting of the plant. Temperature-dependent development, cold tolerance, and the potential distribution of the midge were investigated. The results of the temperature-dependent development study showed that optimal temperatures for larval development were between 20 and 30°C, and these data were used to construct a map of the potential number of generations per year of C. lebetis in Florida. Data from the cold tolerance study, in conjunction with historical weather data, were used to generate a predicted distribution of C. lebetis in the United States. A distribution was also predicted using an ecological niche modeling approach by characterizing the climate at locations where C. lebetis is known to occur and then finding other locations with similar climate. The distributions predicted using the two modeling approaches were not significantly different and suggested that much of the southeastern United States was climatically suitable for C. lebetis
