Retrospective clinical evaluation of root canal treatment with or without photodynamic therapy for necrotic teeth and teeth subjected to retreatment.

2021

PURPOSE To compare the effect of photodynamic therapy (PDT) as a procedure to complement root canal treatment (RCT), for both primary treatment and retreatment. METHODS This was a retrospective study based on analysis of clinical records. A total of 214 teeth that had undergone RCT on either a primary or retreatment basis, with or without complementary PDT, were evaluated. For 118 teeth that met the previously established inclusion criteria, the time until healing was evaluated. Complementarily, the need for application of calcium hydroxide (CaHy) between visits and the number of visits necessary for completing the treatment were assessed. Data were analyzed using the Mann-Whitney and χ2 te…

Analytical parameters and vital signs in patients subjected to dental extraction.

2017

BACKGROUND: Dental consultation may provoke stress to the patient, especially when a dental surgery is going to be performed, stressful situations can cause a reaction in the sympathetic nervous system that could lead to cardiovascular alterations. Blood pressure and cardiac frequency are used often as an indirect measurement and this parameters combined can serve as good indicators of stress. Objective: Analyze the changes in vital signs and analytical parameters induced by a dental extraction. MATERIAL AND METHODS: 24 healthy patients who required a simple dental extraction underwent to a blood test and motorization of their pre- and post-extraction vital signs before, at 2 and 48 hours a…

Muscle cramping in the marathon: dehydration and electrolyte depletion vs. muscle damage

2020

Martinez-Navarro, I, Montoya-Vieco, A, Collado, E, Hernando, B, Panizo, N, and Hernando, C. Muscle Cramping in the marathon: Dehydration and electrolyte depletion vs. muscle damage. J Strength Cond Res XX(X): 000-000, 2020-Our aim was to compare dehydration variables, serum electrolytes, and muscle damage serum markers between runners who suffered exercise-associated muscle cramps (EAMC) and runners who did not suffer EAMC in a road marathon. We were also interested in analyzing race pacing and training background. Nighty-eight marathoners took part in the study. Subjects were subjected to a cardiopulmonary exercise test. Before and after the race, blood and urine samples were collected and…

Efficient Killing of Human Colon Cancer Stem Cells by γδ T Lymphocytes

2009

Abstract Colon cancer comprises a small population of cancer stem cells (CSC) that is responsible for tumor maintenance and resistant to cancer therapies, possibly allowing for tumor recapitulation once treatment stops. We previously demonstrated that such chemoresistance is mediated by autocrine production of IL-4 through the up-regulation of antiapoptotic proteins. Several innate and adaptive immune effector cells allow for the recognition and destruction of cancer precursors before they constitute the tumor mass. However, cellular immune-based therapies have not been experimented yet in the population of CSCs. Here, we show that the bisphosphonate zoledronate sensitizes colon CSCs to Vγ9…

Frequency of polymorphisms of signal peptide of TGF-beta1 and -1082G/A SNP at the promoter region of Il-10 gene in patients with carotid stenosis

2006

The role of inflammation in atherosclerosis is well recognized. We have evaluated the allele frequencies of the +869T/C and +915G/C polymorphisms (SNPs) at the TGF-beta1 gene and -1082G/A SNP at IL-10 promoter sequence, two well-known immunosuppressive and anti-inflammatory cytokines, in patients with carotid stenosis. Our data suggest a lack of association between these SNPs and the susceptibility to atherosclerosis although other reports have demonstrated this association. These results may be due to the pleiotropic effects of the cytokines and/or differences in haplotype combination that should be investigated to elucidate the role of TGF-beta1 and IL-10 polymorphisms in atherosclerosis.

Terahertz polarization-division multiplexing within a four-wire waveguide

2022

We demonstrate a new metal-wire waveguide topology, namely a four-wire waveguide, which simultaneously acts as a broadband terahertz polarization-division multiplexer and as a novel platform to realize the independent manipulation of polarization-division multiplexed terahertz signals.

Nanoelektromehānisko slēdžu vadības sistēmas izveide

2018

Izmantojot divus elektrodus un nanovadu ir iespējams izveidot nanoelektromehānisku sistēmu kas darbojas kā mehānisks slēdzis. Nanovads ir pievienots pie viena elektroda, pieliekot līdzstrāvu starp abiem elektrodiem rodas elektriskais lauks, kas noliec nanovadu pie otra elektroda. Palielinot spriegumu panāk to, ka elektriskā lauka spēks pārsniedz nanovada elastības spēku un tas nonāk kontaktā. Lai to panāktu starp elektrodiem jābūt salīdzinoši lielam līdzspriegumam, kas pēc nonākšanas kontaktā var sabojāt nanovadu. Tāpēc tiek pieslēgts arī maiņspriegums, kas izraisa nanovada mehāniskas svārstības un palīdz tam nonākt kontaktā. Kamēr šis slēdzis nav nonācis kontaktā, starp nanovadu un elektro…

Sulla natura contabile delle "passività monetarie" nei bilanci bancari

2009

Il saggio riapre la discussione sulla natura contabile delle emissioni monetarie, un tempo oggetto di acceso dibattito ed oggi in parte trascurata. Per far ciò conia la categoria concettuale di "passività monetarie" nella quale far confluire tanto le emissioni di moneta legale sotto forma di banconote, propria esclusivamente degli istituti di emissione, quanto le "emissioni" di moneta fiduciaria sotto forma di depositi liberi in conto corrente, questi propri tanto ancora una volta degli istituti di emissione (la moneta "ad alto potenziale") quanto delle banche ordinarie. Il metodo seguito è in gran parte storiografico, sebbene la ricerca non abbia finalità propriamente storiche quanto, piut…

Overvåking av vitale parametere i sykehus : En sammenligning av manuelle og elektroniske overvåkingssystemer

2018

Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 Adverse events can be avoided by timely recognition of derangements in vital signs. Sørlandet Hospital HF (SSHF) has implemented an Early Warning Score System named "TILT"; 2Early identification of life-threatening conditions”. In 2017 SSHF started a project that tested wireless sensors for continuous monitoring of vital signs on wards. Patients were monitored by sensors and vital signs were also measured by traditional means during the project period. The aim of this study was to examine compliance with the vital signs monitoring protocol, and to examine the benefits of an electronic system. The following quest…
