Health has become a priority issue on the agenda in relation to Brazilian international technical cooperation in the last decade. This applies to Mozambique which is a strategic partner of Brazil's when one takes into consideration the volume of projects that have been undertaken between the two countries and the available resources on offer. There has been a shift in the foreign policy paradigm which has resulted in a new Brazilian foreign policy posture that promotes bilateral agreements and international cooperation...

Attention Restoration Theory (ART) states that built scenes place greater load on attentional resources than natural scenes. This is explained in terms of "hard" and "soft" fascination of built and natural scenes. Given a lack of direct empirical evidence for this assumption we propose that perceptual saliency of scene content can function as an empirically derived indicator of fascination. Saliency levels were established by measuring speed of scene category detection using a Go/No-Go detection paradigm. Experiment 1 shows that built scenes are more salient than natural scenes...

The relationship between choice and eye movement has gained marked interest. The gaze bias effect, i.e., the tendency to look longer at items that are eventually chosen, has been shown to occur in the first dwell (initial cohesion of fixations for an item). In the two-alternative forced-choice (2AFC) paradigm, participants would look at one of the items first (defined as first look; FL), and they would then move and look at another item (second look; SL). This study investigated how the order in which the chosen items were looked at modulates the first dwell gaze bias effect...

Frailty is a common condition in older age and is a public health concern which requires integrated care and involves different stakeholders. This meta-synthesis focuses on experiences, understanding, and attitudes towards screening, care, intervention and prevention for frailty across frail and healthy older persons, caregivers, health and social care practitioners. Studies published since 2001 were identified through search of electronic databases; 81 eligible papers were identified and read in full, and 45 papers were finally included and synthesized...

The ability to synthesize information across multiple senses is known as multisensory integration and is essential to our understanding of the world around us. Sensory stimuli that occur close in time are likely to be integrated, and the accuracy of this integration is dependent on our ability to precisely discriminate the relative timing of unisensory stimuli (crossmodal temporal acuity). Previous research has shown that multisensory integration is modulated by both bottom-up stimulus features, such as the temporal structure of unisensory stimuli, and top-down processes such as attention...

SHARPIN (Shank-associated RH domain interacting protein) is the main component of the linear ubiquitin chain activation complex (LUBAC). SHARPIN is involved in regulating inflammation and cancer progression. However, whether SHARPIN plays an important role in lung cancer metastasis and the potential underlying mechanism are still unknown. Here, for the first time, we reported that SHARPIN expression is closely related to lung cancer progression. Moreover, SHARPIN plays a central role in controlling lung cancer cell metastasis...

Curcumin is a natural polyphenol and essential curcuminoid derived from the rhizome of the medicinal plant Curcuma longa (L.) is universally acknowledged as "Wonder drug of life". It is a vital consumable and restorative herb, commonly keened for several ailments such as cancer, arthritis, pain, bruises, gastrointestinal quandaries, swelling and much more. Despite its enormous curative potential, the poor aqueous solubility and consequently, minimal systemic bioavailability with rapid degradation are some of the major factors which restrict the utilization of curcumin at medical perspective...

To detect biochemicals with ultrahigh sensitivity, efficiency, reproducibility, and specificity has been the holy grail in the development of nanosensors. In this work, we report an innovative type of photonic-plasmonic hybrid Raman nanosensor integrated with electrokinetic manipulation by rational design, which offers dual mechanisms that enhance the sensitivity for molecule detection directly in solution. For the first time, we integrate large arrays of synthesized plasmonic nanocapsules with densely surface distributed silver (Ag) nanoparticles (NPs) on lithographically patterned photonic crystal slabs via electric-field assembling...

OBJECTIVE: Intracortical brain-machine interfaces (BMIs) are a promising source of prosthesis control signals for individuals with severe motor disabilities. Previous BMI studies have primarily focused on predicting and controlling whole-arm movements; precise control of hand kinematics, however, has not been fully demonstrated. Here, we investigate the continuous decoding of precise finger movements in rhesus macaques. APPROACH: In order to elicit precise and repeatable finger movements, we have developed a novel behavioral task paradigm which requires the subject to acquire virtual fingertip position targets...

Molecule clustering is an important mechanism underlying cellular self-organization. In the cell membrane, a variety of fundamentally different mechanisms drive membrane protein clustering into nanometre-sized assemblies. To date, it is unknown whether this clustering process can be dissected into steps differentially regulated by independent mechanisms. Using clustered syntaxin molecules as an example, we study the influence of a cytoplasmic protein domain on the clustering behaviour. Analysing protein mobility, cluster size and accessibility to myc-epitopes we show that forces acting on the transmembrane segment produce loose-clusters, while cytoplasmic protein interactions mediate a tightly packed state...

Prion diseases are a class of neurodegenerative disorders characterized by the accumulation in the brain of a self-replicating, misfolded isoform (PrPSc) of the cellular prion protein (PrPC), a cell-surface glycoprotein of uncertain function. Emerging evidence suggests that PrPC may passively serve as a substrate for the replication of PrPSc, and actively transduce its toxic effects to neuronal cells. The vast majority of previous drug screening campaigns have only targeted PrPSc replication, with largely unsuccessful results...

Inadequate dose selection for confirmatory trials is currently still one of the most challenging issues in drug development, as illustrated by high rates of late-stage attritions in clinical development and postmarketing commitments required by regulatory institutions. In an effort to shift the current paradigm in dose and regimen selection and highlight the availability and usefulness of well-established and regulatory-acceptable methods, the European Medicines Agency (EMA) in collaboration with the European Federation of Pharmaceutical Industries Association (EFPIA) hosted a multistakeholder workshop on dose finding (London 4-5 December 2014)...

BACKGROUND/PURPOSE: Focus on the hair and hair cuticle is increasing. The hair cuticle is the first layer to be exposed to damage and the area of primary protection. For such reasons, hair product manufacturers consider cuticle protection important. However, previous studies used only visual assessment to examine the cuticle. This study aimed to obtain the changes in cuticles and measure hair roughness using a HIROX microscope. METHODS: A total of 23 female subjects used the same products daily for 4 weeks...

Individuals with autism spectrum disorder (ASD) can have difficulty recognizing emotional expressions. Here, we asked whether the underlying perceptual coding of expression is disrupted. Typical individuals code expression relative to a perceptual (average) norm that is continuously updated by experience. This adaptability of face-coding mechanisms has been linked to performance on various face tasks. We used an adaptation aftereffect paradigm to characterize expression coding in children and adolescents with autism...

Many industrial sectors, from pharmaceuticals to consumer products, are required to provide data on their products to demonstrate their efficacy and that they are safe for patients, consumers and the environment. This period of testing typically requires the use of animal models, the validity of which has been called into question due to the high rates of attrition across many industries. There is increasing recognition of the limitations of animal models and demands for safety and efficacy testing paradigms which embrace the latest technological advances and knowledge of human biology...

Social connection is a fundamental human need, but challenging for individuals with characteristics that are socially stigmatized. Parenting with mental illness presents obstacles, as well as opportunities, for connection. In the present study, we examined connectedness within a personal recovery paradigm for rural mothers with a mental illness. In-depth interviews with 17 mothers with a mental illness, utilizing constructivist grounded theory, resulted in six categories of meaning, including 'yearning for connection', 'connecting intensely', 'encountering rejection and exclusion', 'choosing isolation', 'being known', and 'finding peers/helping others'...

The development of the various themes of Catholic Social Teaching (CST) is based on numerous papal documents and ecclesiastical statements. While this paper provides a summary of a number of these documents, this paper focuses on two themes: the common good and care of the environment, and on three documents authored by Pope John Paul II in 1990, by Pope Benedict XVI in 2010, and by Pope Francis in 2015. By analyzing these documents from an engineer's perspective, the author proposes a model for Socially Responsible Engineering...

Solubility challenge for a poorly water-soluble drug gets further intensified when it is weakly ionic because the most common solubility enhancement technique, salt formation, becomes less feasible. Salt screening for such drugs often concludes with either a difficult to crystalize salt or an unstable salt, leading the scientists to explore other solubility enhancement technique like amorphous solid dispersions which is comparatively costlier, time-consuming and may require use of hazardous organic solvents...

Emergency medical services provide immediate care to patients with various types of needs. When the system is congested, the response to urgent emergency calls can be delayed. To address this issue, we propose a spatial Hypercube approximation model with a cutoff priority queue that estimates performance measures for a system where some servers are reserved exclusively for high priority calls when the system is congested. In the cutoff priority queue, low priority calls are not immediately served-they are either lost or entered into a queue-whenever the number of busy ambulances is equal to or greater than the cutoff...

Diabetic kidney disease (DKD) is one of the primary causes of end-stage renal disease (ESRD). Early diagnosis is very important in preventing the development of DKD. Urinary albumin excretion rate (UAER) and glomerular filtration rate (GFR) are widely accepted as criteria for the diagnosis and clinical grading of DKD, and microalbuminuria has been recommended as the first clinical sign of DKD. The natural history of DKD has been divided into three stages: normoalbuminuria, microalbuminuria, and macroalbuminuria...
