Urinary Estrogen Metabolites and Self-Reported Infertility in Women Infected wi...

Schistosomiasis is a neglected tropical disease, endemic in 76 countries, that afflicts more than 240 million people. The impact of schistosomiasis on infertility may be underestimated according to recent literature. Extracts of Schistosoma haematobium include estrogen-like metabolites termed catechol-estrogens that down regulate estrogen receptors alpha and beta in estrogen responsive cells. In addition, schis...

Fatigue behaviour of AA6082-T6 MIG welded butt joints improved by friction stir...

Friction Stir Processing (FSP) was based on the principles of Friction Stir Welding (FSW), a solid-state joining process originally developed for aluminium alloys. It is an emerging metalworking technique which can provide localized modification and control of microstructures in near-surface layers of processed metallic components. In this research, FSP appears as an alternative to traditional methods for fatig...

Hypovitaminosis D in Patients Admitted to an Internal Medicine Ward

Introduction: Hypovitaminosis D (hypoD) is a vitamin deficiency that has been rising in the developed countries, due not only to inappropriate eating habits, but also because of lower sun exposure and lack of exercise. Objective: To determine the prevalence of vitamin D deficiency and to analyze associated factors, in patients admitted to an Internal medicine Ward. Methods: Cross-sectional study which included ...

Deficit irrigation in Mediterranean vineyards - a tool to increase water use ef...

IHC - IS Viti&Climate: Effect of Climate Change on Production and Quality of Grapevines and their Products, 28 th, 2012 ; Water is increasingly scarce in Mediterranean Europe and irrigated agriculture is one of the largest and most inefficient users of this natural resource. Ecological topics such as the “water foot print” have become more relevant for the academy, consumers, governments and food industry. The...

Digital ulcers in systemic sclerosis: use of endotheline antagonists.

Systemic sclerosis (SSc) is a systemic disease, characterized by fibrosis and vasculopathy, with variable internal organ involvement. Skin is very often involved, namely digital ulcers (DU), seldom treatment resistant, responsible for important functional limitation. The DU can evolve from sclerodactily with superficial ulcers, isquemic lesions, deep necrosis, gangrene, loss of tissue, and consequently, to fing...

Undifferentiated osteoclastic-type giant cell carcinoma.

Initially described 40 years ago (Rosai), the undifferentiated osteoclastic-type giant cell carcinoma (IOGCC) is a variant of ductal adenocarcinoma and accounts for less than 1% of exocrine pancreatic tumors. Its extreme rarity, with consequent existence of few reports and clinical experience, leads to the arousal of doubts with regard to its histogenesis, types of approach and therapeutical attitudes. It is im...

Deficit irrigation in Mediterranean environment. What lessons have we learnt fr...

Libro de Actas - X Simposium Hispano Português de Relaciones Hidricas, 2010 ; Deficit irrigation techniques, implying that water is supplied at levels below full crop evapotranspiration throughout the growing season or in specific phenological stages, such as regulated deficit irrigation (RDI) or partial root drying (PRD), emerged as potential strategies to increase water savings with marginal decreases of yie...

Grapevine under deficit irrigation: hints from physiological and molecular data

Background - A large proportion of vineyards are located in regions with seasonal drought (e.g. Mediterraneantype climates) where soil and atmospheric water deficits, together with high temperatures, exert large constraints on yield and quality. The increasing demand for vineyard irrigation requires an improvement in the efficiency of water use. Deficit irrigation has emerged as a potential strategy to allow c...
