Flor yeasts confer a wide range of organoleptic properties to Sherry-type wines during a process called "biological aging" that takes place after alcoholic fermentation. These kinds of yeasts adapt to a biological aging condition by forming a biofilm known as "flor velum" and by changing from fermentative to oxidative metabolism. It has been reported that some functions such as increase of cell surface hydrophobicity or changes to lipid metabolism are enhanced when yeasts switch to biofilm lifestyle...

BACKGROUND: Cardiac amyloidosis is an underdiagnosed cause of restrictive cardiomyopathy resulting from the infiltration of the myocardium by amyloid proteins. CASE REPORT: We report the case of an 83-year-old woman who presented with increasing dyspnea and lower-extremity swelling. She reported a medical history of unspecified heart failure. Evaluation in the Emergency Department (ED) revealed evidence of heart failure on physical examination, low-voltage electrocardiogram, chest x-ray study with mild pulmonary edema, and laboratory evaluation with elevated brain natriuretic peptide and troponin...

The increased consumption of tobacco products in recent years has been linked, among other factors, to the presence of added flavors. Although flavors are important in explaining consumption, their effects in the brain have until now been unexplored. In the present study, we investigated how electrophysiology can serve to dissociate the effects of nicotine and flavor. Participants attended 4 sessions (2-by-2 factorial design, with flavor and nicotine as within-subject factors), in each session an oddball task was performed before and after smokeless tobacco consumption...

REVIEW
Mauricio Morais, Michelle T Ma
Antibodies and their derivatives radiolabelled with positron- and gamma-emitting radiometals enable sensitive and quantitative molecular Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) imaging of antibody distribution in vivo. Chelators that are covalently attached to antibodies allow radiolabelling with metallic PET and SPECT radioisotopes. Conventional strategies for chelator-protein conjugation generate heterogeneous mixtures of bioconjugates that can exhibit reduced affinity for their receptor targets, and undesirable biodistribution and pharmacokinetics...

Are mathematical learning difficulties caused by impairment of the abilities that underlie mathematical talent? Or are mathematical difficulties and talent qualitatively different? The main goal of this study was to determine whether mathematical learning difficulties are explained by the same executive functions as mathematical talent. We screened a pool of 2,682 first-year high school students and selected 48 for evaluation, dividing them into three groups: those with mathematical learning difficulties (n = 16), those with typical performance (n = 16), and those with mathematical talent (n = 16)...

Idiopathic Pulmonary Fibrosis (IPF) pathogenesis has been postulated to involve a variety of mechanisms associated with the aging process, including loss of protein homeostasis (proteostasis). Heat shock proteins (Hsp) are cellular chaperones that serve a number of vital maintenance and repair functions, including the regulation of proteostasis. Previously published data have implicated Hsp70 in the development of pulmonary fibrosis in animal models. We sought to identify alterations in Hsp70 expression in IPF lung...

Background: Graft rupture rate, return to sport and persistent rotational instability remain a concern postoperatively following anterior cruciate ligament (ACL) reconstruction. The anterolateral ligament (ALL) has recently been shown to act as a lateral knee stabilizer that helps improve rotational stability. To improve functional and clinical outcomes, a combined ACL reconstruction with an associated ALL reconstruction has been proposed. Purpose: The main purpose of this study was to evaluate the clinical outcomes of the combined ACL and ALL reconstruction...

Approximately 50% of rhesus macaques (RMs) expressing the major histocompatibility complex class I (MHC-I) allele Mamu-B*08 spontaneously control chronic phase viremia after infection with the pathogenic simian immunodeficiency virus (SIV)mac239 clone. CD8+ T-cell responses in these animals are focused on immunodominant Mamu-B*08-restricted SIV epitopes in Vif and Nef, and prophylactic vaccination with these epitopes increases the incidence of elite control in SIVmac239-infected Mamu-B*08+ RMs. Here we evaluated if robust vaccine-elicited CD8+ T-cell responses against Vif and Nef can prevent systemic infection in Mamu-B*08+ RMs following mucosal SIV challenges...

OBJECTIVE: To assess the control of cLDL in diabetic patients, to measure the impact on such control of inertia with lipid-lowering agents and to explore factors that allow for predicting this inertia. METHODS: Study of historical cohorts of diabetic patients. The proportion of patients who achieved the target cLDL levels was estimated. Therapeutic inertia was considered when the dose of the lipid-lowering agents was not adjusted, or a lipid-lowering agent was not changed or added in patients with initial cLDL outside the target...

Plant protein kinases form redundant signaling pathways to perceive microbial pathogens and activate immunity. Bacterial pathogens repress cellular immune responses by secreting effectors, some of which bind and inhibit multiple host kinases. To understand how broadly bacterial effectors may bind protein kinases and the function of these kinase interactors, we first tested kinase-effector (K-E) interactions using the Pseudomonas syringae pv. tomato-tomato pathosystem. We tested interactions between five individual effectors (HopAI1, AvrPto, HopA1, HopM1, and HopAF1) and 279 tomato kinases in tomato cells...

Garnet-structured Li7 La3 Zr2 O12 is a promising solid electrolyte for next-generation solid-state Li batteries. However, sufficiently fast Li-ion mobility required for battery applications only emerges at high temperatures, upon a phase transition to cubic structure. A well-known strategy to stabilize the cubic phase at room temperature relies on aliovalent substitution; in particular, the substitution of Li+ by Al3+ and Ga3+ ions. Yet, despite having the same formal charge, Ga3+ substitution yields higher conductivities (10-3 S/cm) than Al3+ (10-4 S/cm)...

The capsalid monogenean Neobenedenia melleni is known as a lethal pathogen for captured marine teleost ornamental fish, if left untreated. This study reports the occurrence of N. melleni parasitizing four species of ornamental reef fish imported into Brazil and maintained in quarantine: Arabian angelfish (Pomacanthus asfur ), yellowbar angelfish (Pomacanthus maculosus), regal angelfish (Pygoplites diacanthus), and bluecheek butterflyfish (Chaetodon semilarvatus). Ten days after the beginning of quarantine, some fish showed behavioral alterations, such as irritability, and corneal opacity, which were rapidly diagnosed to be caused by monogenean parasites by body surface scraping...

This paper aims at proposing validated principles to underpin clinical management as a means to transform healthcare for integrated healthcare systems. The starting point was the conception of clinical management based on structuring elements that do not separate management, care and education. The authors' proposal was submitted to specialists so that a consensus could be reached. At the end of the process, the following principles of clinical management were presented: (1) Focus on health needs and comprehensive care, (2) Quality and safety in healthcare, (3) Articulation and legitimation of different health practices and types of knowledge to face health problems, (4) Power sharing and co-accountability among managers, health professionals and citizens in healthcare production; (5) Education of people and organizations; (6) Focus on outcomes that add value to health and life; (7) Transparency and accountability regarding collective interests...

BACKGROUND: Diastasis of the rectus abdominis muscles (DMRA) is frequent and may be associated with abdominal wall hernias. For patients with redudant skin, dermolipectomy and plication of the diastasis is the most commonly used procedure. However, there is a significant group of patients who do not require skin resection or do not want large incisions. AIM: To describe a "new" technique (subcutaneous onlay laparoscopic approach - SCOLA) for the correction of ventral hernias combined with the DMRA plication and to report the initial results of a case series...

Asthma and allergy affect hundreds of millions of people from childhood to old age. In most of them, the inflammatory process of respiratory allergies involves the participation of type 2 cytokines, derived from T helper-2 (Th2)-cell, and Group 2 Innate Lymphoid (ILC2) Cells. An efficient memory Th2 cell response is dependent on IL-13 produced by ILC2s, causing allergic lung inflammation and elevated serum levels of immunoglobulin E. ILC2 cells are derived from common lymphoid progenitors and their growing depends on the transcription factor RORA...
