Preface
(Karger, 2017-04)In spite of the increased attention devoted to the literature and by health ministries, overweight and obesity prevalence continues to increase worldwide [1] . A systematic analysis performed in 2013 referred to the global ... -
Improving diabetes care at primary care level with a multistrategic approach: results of the DIAPREM programme
(Springer, 2017-06)To present results, 1 year postimplementation at primary care level, of an integrated diabetes care programme including systemic changes, education, registry (clinical, metabolic, and therapeutic indicators), and disease ... -
Predictive value of galectin-1 in the development and progression of HIV-associated lymphoma
(Lippincott Williams, 2017-10-23)At AHIV-1 infection, the binding of the viral envelopeproteins to CD4þ is essential for viral transmission, andthis process is facilitated by interaction with the highlyconserved host lectin, galectin-1 (Gal-1) [1?3]. ... -
A mucin-like peptide from Fasciola hepatica instructs dendritic cells with parasite specific Th1-polarizing activity
(Nature Publishing Group, 2017-01-12)Fasciolosis is a trematode zoonosis of interest in public health and cattle production. We report here the immunostimulatory effect of a 66 mer mucin-like peptide from Fasciola hepatica (Fhmuc), which synergizes with ... -
AKT1 and AKT2 isoforms play distinct roles during breast cancer progression through the regulation of specific downstream proteins
(Nature Publishing Group, 2017-03)The purpose of this study was to elucidate the mechanisms associated with the specific effects of AKT1 and AKT2 isoforms in breast cancer progression. We modulated the abundance of specific AKT isoforms in IBH-6 and T47D ... -
ERα and GnRH co-localize in the hypothalamic neurons of the South American plains vizcacha, Lagostomus maximus (Rodentia, Caviomorpha)
(Springer, 2017-06)Gonadotropin-releasing hormone (GnRH) is the key regulator of the hypothalamic-pituitary-gonadal axis. Estradiol (E2) affects GnRH synthesis and delivery. Hypothalamic estrogen receptors (ER) modulate GnRH expression acting ... -
Potential biomarkers with plasma cortisol, brain-derived neurotrophic factor and nitrites in patients with acute ischemic stroke
(Bentham Science Publishers, 2017-12)Acute Ischemic Stroke (AIS) represents an economic challenge for health systems all over the globe. Changes of neuroactive steroids have been found in different neurological diseases. We have previously demonstrated that ... -
An intact acrosome is required for the chemotactic response to progesterone in mouse spermatozoa
(Wiley-liss, Div John Wiley & Sons Inc, 2017-04)Mammalian sperm become fertilization-competent in the oviduct, during a process known as capacitation that involves the acquisition of the ability to exocytose the acrosome but also the chemotactic responses—both of which ... -
Gene expression regulation by heat-shock proteins: the cardinal roles of HSF1 and Hsp90
(Portland Press, 2017-02)The ability to permit gene expression is managed by a set of relatively well known regulatory mechanisms. Nonetheless, such property can also be acquired during the life span as a consequence of environmental stimuli. ... -
Study of the effect of ulipristal acetate on human sperm ability to interact with tubal tissue and cumulus-oocyte-complexes
(Elsevier Science Inc, 2017-06)Ulispristal acetate (UPA) is a selective progesterone receptor modulator widely used for emergency contraception (EC). The described main mechanism of action is by inhibiting or delaying ovulation; however, the postovulatory ... -
Distribution, spatial interaction and niche analysis in three species of European moles (genus Talpa, Soricomorpha: Mammalia) in Italy
(Wiley Blackwell Publishing, Inc, 2017-12)We investigated the spatial relationships among three phylogenetically related and ecologically convergent moles in Italy: Talpa europaea, Talpa romana and Talpa caeca. The spatial niche of each species was described through ... -
Power conditioning system coupled with a flow battery for wind energy applications: Modelling and control design
(Institution of Engineering and Technology, 2017-06)Wind generation (WG) is the most widespread renewable energy resource in the world. However, this implementation inevitably leads to an increase in the problems caused by WG, e.g. frequency oscillations, power fluctuations ... -
Assessing degradation of power transformer solid insulation considering thermal stress and moisture variation
(Elsevier Science Sa, 2017-10)This paper presents a novel method for estimating the degradation of solid insulation in power transformers, considering thermal ageing and paper moisture dynamics. Current ageing models are based on both, experimental ... -
Energy Storage and Power Electronics Technologies: A Strong Combination to Empower the Transformation to the Smart Grid
(Institute of Electrical and Electronics Engineers, 2017-11)The electric power industry is facing unprecedented transformations and challenges with the implementation of the smart grids. This new grid paradigm has arisen to build a flexible electric power system that better coordinates ... -
Effects of atrazine on ovarian growth, in the estuarine crab Neohelice granulata
(Elsevier Science Inc, 2017-02)Atrazine, a herbicide that is intensively used in Argentina, was assayed to evaluate the alteration of reproduction in a wild species of crustaceans. Adult females of the estuarine crab Neohelice granulata were exposed to ... -
Male reproductive traits of the marine snail Buccinanops deformis (King, 1832), (Gastropoda: Nassariidae): Size and age at maturity and sperm morphology
