La transversalidad de los trastornos del comportamiento alimentario: un reto para los cuidados de salud
2004
Los trastornos de la conducta alimentaria son una causa importante de morbilidad física y psicosocial en jóvenes adolescentes y en mujeres adultas jóvenes y, aunque en distinto grado, afectan a personas tanto de países desarrollados como de países en vías de desarrollo. En este trabajo se expone como ejemplo la situación España y Perú. Se trata de un problema de origen multicausal que es transversal a condiciones socioeconómicas y clase social y en la actualidad, es la teoría del factor sociocultural la que mejor soporta la interpretación de los datos disponibles. En este contexto, el rol y la responsabilidad que compete a Enfermería y a otros profesionales de la salud tiene grandes dimensi…
Highly selective fluorescence detection of hydrogen sulfide by using an anthracene-functionalized cyclam-CuII complex
2013
An anthracene-functionalised cyclam-copper(II) complex for the detection of HS- in aqueous environments has been prepared. This probe displays poor fluorescence but can selectively and sensitively detect HS- anions in water over other anions, biothiols and common oxidants such as H2O2 through remarkably enhanced emission. This turn-on response in the presence of the HS- anion is ascribed to a demetallation reaction that inhibits emission quenching observed in the initial complex as a result of the presence of the paramagnetic Cu2+ centre. Moreover, real-time fluorescence imaging measurements confirm that probe [Cu(1)](2+) can be easily used to detect intracellular HS- at micromolar concentr…
Selective Antimicrobial Effects of Curcumin@Halloysite Nanoformulation: A Caenorhabditis elegans Study
2019
Alterations in the normal gastrointestinal microbial community caused by unhealthy diet, environmental factors, and antibiotic overuse may severely affect human health and well-being. Novel antimicrobial drug formulations targeting pathogenic microflora while not affecting or even supporting symbiotic microflora are urgently needed. Here we report fabrication of a novel antimicrobial nanocontainer based on halloysite nanotubes loaded with curcumin and protected with a dextrin outer layer (HNTs+Curc/DX) and its effective use to suppress the overgrowth of pathogenic bacteria in Caenorhabditis elegans nematodes. Nanocontainers have been obtained using vacuum-facilitated loading of hydrophobic …
Mullarian-inhibiting substance reflects ovarian findings in women with polycystic ovary syndrome better than does inhibin-B
2005
Objective: To investigate Müllerian-inhibiting substance (MIS) levels in women with polycystic ovary syndrome (PCOS), as well as relationships to ovarian morphology, levels of inhibin B, and other reproductive hormones. Design: Prospective clinical study. Setting: Academic endocrinology centers in Palermo, Italy and New York. Patient(s): Forty-six women with PCOS, recruited on the basis of the classic criteria of chronic anovulation and hyperandrogenism, and 25 age-matched ovulatory controls. Intervention(s): Fasting blood was obtained in all subjects in the early follicular phase (days 5–6) after spontaneous or induced menses (in PCOS), and transvaginal ultrasounds were performed. Main Out…
A promising new ELISA diagnostic test for cattle babesiosis based on Babesia bigemina Apical Membrane Antigen-1.
2016
Babesiosis due to Babesia bigemina is a relevant tick‑borne disease, affecting cattle worldwide. Many surface proteins of the pathogen including the Apical Membrane Antigen 1 (AMA‑1) ‑ have been analysed for vaccine and diagnostic purposes. This study focused on B. bigemina AMA‑1 and on its use for the assessment of diagnostic tests. After bioinformatic analyses, AMA‑1 codifying region was amplified and cloned into an expression vector used to induce protein synthesis in Escherichia coli cells. AMA‑1 was purified by affinity chromatography and used to set up the best condition for an ELISA protocol. Bovine field sera positive to B. bigemina were used to evaluate the presence of anti‑AMA‑1 a…
Peritoneal Cavity is a Route for Gut-Derived Microbial Signals to Promote Autoimmunity in Non-Obese Diabetic Mice
2015
Macrophages play a crucial role in innate immune reactions, and peritoneal macrophages (PMs) guard the sterility of this compartment mainly against microbial threat from the gut. Type 1 diabetes (T1D) is an autoimmune disease in which gut microbiota and gut immune system appear to contribute to disease pathogenesis. We have recently reported elevated free radical production and increased permeability of gut epithelium in non-obese diabetic (NOD) mice. Impaired barrier function could lead to bacterial leakage to the peritoneal cavity. To explore the consequences of impaired gut barrier function on extra-intestinal immune regulation, we characterized peritoneal lavage cells from young newly w…
Toxicological and bioactivity evaluation of blackcurrant press cake, sea buckthorn leaves and bark from Scots pine and Norway spruce extracts under a…
2021
Aqueous extracts from blackcurrant press cake (BC), Norway spruce bark (NS), Scots pine bark (SP), and sea buckthorn leaves (SB) were obtained using maceration and pressurized hot water and tested for their bioactivities. Maceration provided the extraction of higher dry matter contents, including total phenolics (TPC), anthocyanins, and condensed tannins, which also impacted higher antioxidant activity. NS and SB extracts presented the highest mean values of TPC and antioxidant activity. Individually, NS extract presented high contents of proanthocyanidins, resveratrol, and some phenolic acids. In contrast, SB contained a high concentration of ellagitannins, ellagic acid, and quercetin, exp…
Projekts: SIA "HANG IT UP" dibināšana
2017
Maģistra darba mērķis ir izstrādāt finansiāli izdevīgu projektu izveidojot jaunu uzņēmumu vai arī attīstot jau strādājoša uzņēmuma darbību. Darba autors ir izvēlējies projekta izstrādes ietvaros dibināt uzņēmumu SIA “HANG IT UP”, kurš nodarbotos ar garderobes un mantu glabāšanas biznesu. Projekta ideja ir izveidot produktu, kas palīdzētu attīstīt garderobju un mantu glabātuvju nozari. Ierastās garderobes pilda tikai un vienīgi vienu funkcija – saņemt no klientiem virsdrēbes un vēlāk tās atgriezt atpakaļ, bet no šīs vienkāršās funkcijas ir iespējams iegūt arī papildus pievienotu vērtību. Īstenojot projekta ideju, tiktu izveidota aplikācija, kura tiktu izmantota ierasto garderobes numuriņu vi…

2018
ABSTRACTAn earlier method for obtaining indefinite integrals of special function from the second-order linear equations which define them has been reformulated in terms of Riccati equations, which ...
Best approximation and variational inequality problems involving a simulation function
2016
We prove the existence of a g-best proximity point for a pair of mappings, by using suitable hypotheses on a metric space. Moreover, we establish some convergence results for a variational inequality problem, by using the variational characterization of metric projections in a real Hilbert space. Our results are applicable to classical problems of optimization theory.
