The organization of the prefrontal cortex can hold important clues to understanding its functioning. The Cebus apella present cerebral particularities and behavioral and cognitive flexibility, possessing abilities that demonstrate an overlap with those of big primates. Objectives: To provide evidence of correlations between anatomical particularities of the brain areas analyzed and some cogniti...

Human herpesvirus-6 (HHV-6) is a major cause of limbic encephalitis with a dismal prognosis after allogeneic hematopoietic stem cell transplantation (SCT). Because our previous trial of preemptive therapy with foscarnet sodium (phosphonoformic acid; PFA) failed to prevent HHV-6 encephalitis, we conducted a prospective study to examine the safety of prophylactic PFA administration and elucidate ...

Introduction: La Commission Régionale de Certification de l’Eradication de la poliomyélite pour l’Afrique(CRCA) en session à Brazzaville du 8 au 10 octobre 2007 avait déclaré la Mauritanie « libérée de la poliomyélite ». Objectif: Décrire l’épidémiologie des PFA (Paralysies flasques aigues) et évaluer les indicateurs de performance du système de surveillance pour la période de 2008 à 2012 ayant...

BACKGROUND Dysvascular partial foot amputation (PFA) is a common sequel to advanced peripheral vascular disease. Helping inform difficult discussions between patients and practitioners about the level of PFA, or the decision to have a transtibial amputation (TTA) as an alternative, requires an understanding of the current research evidence on a wide range of topics including wound healing, ream...

Abstract Funding Acknowledgements Type of funding sources: None. Background A multipolar pulsed-field ablation (PFA) catheter has recently been introduced and showed favorable data in terms safety procedural efficiency pulmonary vein isolation (PVI) for atrial fibrillation (AF). Long-term outcome comparison to other modalities however is lacking. Purpose To compare one-year recurrence patients ...

Use of humic acid has great significance to improve soil quality and crop yield in loess hilly gully areas. In the present study, potassium humate (PH) fulvic (PFA) were used as amendments control project area Yan'an City, Shaanxi Province. A pot culture experiment was conducted evaluate influence two types (PH PFA) on growth characteristics ryegrass area. Results showed that application consid...

Food is acquired (obtained by foraging) and frequently stored (hoarded) across animal taxa, including humans, but the physiological mechanisms underlying these behaviors are virtually unknown. We found that peptides that stimulate food intake in rats stimulate food foraging and/or hoarding more than intake in Siberian hamsters. Neuropeptide Y (NPY) is a potent orexigenic peptide that increases ...

A Σ21 truth for λ is a pair 〈Q,ψ〉 so that Q ⊆ Hλ, ψ is a first order formula with one free variable, and there exists B ⊆ H λ+ such that (H λ+ ;∈, B) |= ψ[Q]. A cardinal λ is Σ21 indescribable just in case that for every Σ 2 1 truth 〈Q,ψ〉 for λ, there exists λ̄ < λ so that λ̄ is a cardinal and 〈Q ∩ Hλ̄, ψ〉 is a Σ 2 1 truth for λ̄. More generally, an interval of cardinals [κ, λ] with κ ≤ λ is Σ21 in...

In this paper, an analytical framework is presented for device detection in impulse radio (IR) ultra-wide bandwidth (UWB) system and its performance analysis carried out. The Neyman–Pearson (NP) criteria employed device-free detection. Different from the frequency-based approaches, proposed method utilizes time domain concepts. characteristic function (CF) utilized to measure moments of presenc...

The increased application of catheter ablation to treat cardiac arrhythmias has contributed continued exploration safe and effective tissue tools in the field electrophysiology. Pulsed (PFA), a novel recently developed non-thermal energy-based technique, uses trains microsecond duration high-amplitude pulses ablate target cells. Several preclinical clinical studies have demonstrated that PFA is...
