Gladys Barragan-Jason, Cristina M Atance
Patience in children has usually been studied using delay of gratification paradigms. However, another important aspect of patience that has not been well documented is the ability to adjust one's behavior while waiting without an explicit reward as a motivator (e.g., sitting in the doctor's waiting room). To examine this aspect of patience, video-recordings of sixty-one 3- and 4-year olds waiting for two separate 3-min periods were examined and coded for children's spontaneous behaviors. We found that 4-year olds displayed more patient (i...

BACKGROUND: Among the 3 approved oral P2Y12 inhibitors for the treatment for patients with acute coronary syndrome (ACS), ticagrelor, but not prasugrel or clopidogrel, has been associated with off-target properties, such as improved endothelial-dependent vasomotion and increased adenosine plasma levels. METHODS: The HI-TECH study (NCT02587260) is a multinational, randomized, open-label, crossover study with a Latin squares design, conducted at 5 European sites, in which patients free from recurrent ischemic or bleeding events ≥30 days after a qualifying ACS were allocated to sequentially receive a 30 ± 5-day treatment with prasugrel, clopidogrel, and ticagrelor in random order...

BACKGROUND: The 2012 London declaration which committed to "sustaining, expanding and extending drug access programmes to ensure the necessary supply of drugs and other interventions to help control soil-transmitted helminths (STH) by 2020" has seen many countries in Africa roll out mass drug administration (MDA) especially among school age children. In Kenya, however, during the National school-based deworming exercise, pre-school aged children (PSAC) have to access treatment at primary schools as the pre-school teachers are not trained to carry out deworming...

Vegetable oil based hybrid films were developed thanks to a novel solvent- and heating-free method at the air-water interface using silylated castor oil cross-linked via a sol-gel reaction. To understand the mechanism of the hybrid film formation, the reaction kinetics was studied in detail by using complementary techniques: rheology, thermogravimetric analysis, and infrared spectroscopy. The mechanical properties of the final films were investigated using nano-indentation, whereas their structure was studied using a combination of wide-angle X-ray scattering, electron diffraction, and atomic force microscopy...

Individuals with serious mental illness (SMI) experience significant comorbid chronic pain (CP). Little is known about CP management in psychiatric inpatient settings. To address this gap in clinical practice, the authors developed CP management group psychotherapy for adult inpatients with SMI. In this report, the authors highlight (1) the theoretical underpinnings of and execution of the psychotherapy group, (2) the characteristics of participants in the pilot phase of the group, and (3) outcomes of group participants...

The 18-mer anionic peptide GK-1 has been successfully employed to improve the immunogenicity and protective response induced by the influenza vaccine and exhibited some degree of protection against experimental murine melanoma. In this study, a sensitive and quantitative reversed-phase HPLC method was developed to study GK-1 stability under different pH, temperature and storage time. The analysis was carried out on a Sunfire C18 column with mobile phase of acetonitrile-water containing 0.02% TFA. The detection was performed on an UV/Vis Detector at 220nm...

Yannick Glady, Robert M French, Jean-Pierre Thibaut
Children's improved performance with age in analogy tasks has been explained by an increase in semantic knowledge of the items and the relations between them or by the development of an increased ability to inhibit irrelevant information. We tested the so-called "unbalanced attentional focus hypothesis" that claims that a failure to choose the "analogical" match can be the result of a difficulty to focus on all the relevant information available. Previous eye-tracking research has suggested, in analogies of the A:B::C:D format, that 5-6 year-olds organize their search around the C item...

Zoonotic diseases will maintain a high level of public policy attention in the coming decades. From the spectre of a global pandemic to anxieties over agricultural change, urbanization, social inequality and threats to natural ecosystems, effectively preparing and responding to endemic and emerging diseases will require technological, institutional and social innovation. Much current discussion emphasizes the need for a 'One Health' approach: bridging disciplines and sectors to tackle these complex dynamics...

Photoconversion of fluorescent proteins by blue and complementary near-infrared light, termed primed conversion (PC), is a mechanism recently discovered for Dendra2. We demonstrate that controlling the conformation of arginine at residue 66 by threonine at residue 69 of fluorescent proteins from Anthozoan families (Dendra2, mMaple, Eos, mKikGR, pcDronpa protein families) represents a general route to facilitate PC. Mutations of alanine 159 or serine 173, which are known to influence chromophore flexibility and allow for reversible photoswitching, prevent PC...

Anetoderma is a rare benign condition of diverse etiology whose characteristic is the diminution or absence of the dermal elastic fibers. Classified as primary and secondary, the latter associated with tumors, inflammatory, and infectious diseases. Although the etiology of the lesions is well described in literature, the pathogenesis is still poorly determined. Anetoderma in syphilis is rare, and occurs even in the most uncommon cutaneous manifestations of the disease, such as the nodular form. In order to better understand the changes that lead to elastolysis, we propose a better correlation with the histopathological findings of the lesions that precede it...

Cell-cell communication is dependent on GJ (gap junction) proteins such as Cx43 (connexin 43). We previously demonstrated the importance of Cx43 function in establishing the enhanced pregnancy vasodilatory phenotype during pregnancy in uterine artery endothelial cells from pregnant (P-UAEC) ewes. Cx43 is regulated by elevating cAMP and PKA (protein kinase A)-dependent Cx43 S365 phosphorylation-associated trafficking and GJ open gating, which is opposed by PKC (protein kinase C)-dependent S368 phosphorylation-mediated GJ turnover and closed gating...

Bovine enzootic haematuria (BEH) is caused by prolonged ingestion of toxic principles of bracken fern, essentially by Pteridium spp. In northwestern Argentina, this disease has a great economic impact ant it is attributed a chronic consumption to Pteridium arachnoideum. This paper describes two endemic areas for enzootic hematuria due to the consumption of Pteris deflexa and Pteris plumula. Two areas where P. deflexa and P. plumula are endemic, but free of Pteridium species, were devised and seven farms were visited...

REVIEW
Gladys O Latunde-Dada
Ferroptosis is a form of regulated cell death that is dependent on iron and reactive oxygen species (ROS) and is characterized by lipid peroxidation. It is morphologically and biochemically distinct and disparate from other processes of cell death. As ferroptosis is induced by inhibition of cysteine uptake or inactivation of the lipid repair enzyme glutathione peroxidase 4 (GPX4), the process is favored by chemical or mutational inhibition of the cystine/glutamate antiporter and culminates in the accumulation of reactive oxygen species (ROS) in the form of lipid hydroperoxides...

Premature mortality due to cardiovascular disease in those with schizophrenia is the largest lifespan disparity in the US and is growing; adults in the US with schizophrenia die, on average, 28 years earlier than those in the general population. The rate of smoking prevalence among individuals with schizophrenia is estimated to be from 64 to 79%. Smokers with schizophrenia have historically been excluded from most large nicotine-dependence treatment studies. However, converging evidence indicates that a majority of smokers with schizophrenia want to quit smoking, and that available pharmacotherapeutic smoking cessation aids are well tolerated by this population of smokers and are effective when combined with behavioral treatment...

Fluorescent dyes are commonly used in the sterile insect technique (SIT) for marking insects for a proper identification after recapture. However, the quality of the mark must be balanced against insect performance, because dyes can negatively affect some parameters of insect performance and reduce their effectiveness in control with the SIT. We determined the visibility and persistence and the effect of dyes on the quality of Anastrepha obliqua (Macquart) and Anastrepha ludens (Loew) (bisexual and genetic sexing strains) by testing four concentrations of a dye (Day-Glo) from 0 to 2...

Rett syndrome (RTT) is an X-linked progressive neurodevelopmental disorder that primarily affects females. Mutations in the MECP2 gene have been attributed as the major genetic cause of RTT. Recently, mutations in CDKL5 and FOXG1 genes have also been suggested to give rise to RTT, although subsequent more extensive studies suggest that diseases resulting from mutations in these two genes should be considered as distinct clinical entities. While the genetic basis for the RTT has been recognized, so far there is no effective cure for the disease and the treatments available are mainly aimed at ameliorating clinical problems associated with the disorder...
