Implicit and explicit learning in reactive and voluntary saccade adaptation.

Saccades can either be elicited automatically by salient peripheral stimuli or can additionally depend on explicit cognitive goals. Similarly, it is thought that motor adaptation is driven by the combination of a more automatic, implicit process and a more explicit, cognitive process. However, the degree to which such implicit and explicit learning contribute to the adaptation of more reactive and voluntary saccades remains elusive. To study this question, we employed a global saccadic adaptation paradigm w...

Fish (53.01 ± 1.0 g) were fed with a basal diet supplemented with 0 gkg (CT), 3 gkg (BS3), 5 gkg-1 (BS5) 7 gkg-1 (BS7) and 10 gkg-1 (BS10) of the probiotic BS for 4 weeks. At the end of the feeding trial, the weight gain, specific growth rate, and fe...

Stimulating brain recovery after stroke using theranostic albumin nanocarriers loaded with nerve growth factor in combination therapy.

For many years, delivering drug molecules across the blood brain barrier has been a major challenge. The neuropeptide nerve growth factor is involved in the regulation of growth and differentiation of cholinergic neurons and holds great potential in the treatment of stroke. However, as with many other compounds, the biomolecule is not able to enter the central nervous system. In the present study, nerve growth factor and ultra-small particles of iron oxide were co-encapsulated into a chemically crosslinked ...


THERAPEUTIC IMPLICATION OF VASCULAR ENDOTHELIAL GROWTH FACTOR RECEPTOR-1 (VEGFR-1) TARGETING IN CANCER CELLS AND TUMOR MICROENVIRONMENT BY COMPETITIVE AND NON-COMPETITIVE INHIBITORS.

The vascular endothelial growth factor receptor-1 (VEGFR-1) is a tyrosine kinase receptor for VEGF-A, VEGF-B, and placental growth factor (PlGF) ligands that is expressed in endothelial, myelomonocytic and tumor cells. VEGF-B and PlGF exclusively bind to VEGFR-1, whereas VEGF-A also binds to VEGFR-2. At variance with VEGFR-2, VEGFR-1 does not play a relevant role in physiological angiogenesis in the adult, while it is important in tumor-associated angiogenesis. VEGFR-1 and PlGF are expressed in a variety of...

Valproic acid inhibits the protective effects of stromal cells against chemotherapy in breast cancer: Insights from proteomics and systems biology.

Interaction between tumor and stromal cells is beginning to be decoded as a contributor to chemotherapy resistance. Here, we aim to take a system-level approach to explore a mechanism by which stromal cells induce chemoresistance in cancer cells and subsequently identify a drug that can inhibit such interaction. Using a proteomic dataset containing quantitative data on secretome of stromal cells, we performed multivariate analyses and found that bone-marrow mesenchymal stem cells (BM-MSCs) play the most pro...

Xylose metabolism in the pig.

It is important to understand if, and to what extent, the pig can utilize xylose as an energy source if xylanase releases free xylose in the small intestine. The experimental objectives were to determine the effects of industry-relevant dietary xylose concentrations and adaptation time on xylose retention efficiency and metabolism, diet digestibility and energy value, nitrogen balance, and hindgut fermentation. Forty-eight pigs were housed in metabolism crates and randomly assigned to one of four treatments...

CINP is a novel cofactor of KLF5 required for its role in the promotion of cell proliferation, survival, and tumor growth.

Krüppel-like factor 5 (KLF5) both suppresses and promotes tumor growth depending on cellular context. The mechanisms underlying tumor promotion could be targetable for therapy. Although a number of transcriptional targets of KLF5 have been identified and implicated in KLF5-mediated tumor growth, how KLF5 regulates these genes remains to be addressed. Here we performed co-immunoprecipitation (co-IP) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) in the TSU-Pr1 bladder cancer cell line, in whi...

Root and shoot variation in relation to potential intermittent drought adaptation of Mesoamerican wild common bean (Phaseolus vulgaris L.).

Wild crop relatives have been potentially subjected to stresses on an evolutionary time scale prior to domestication. Among these stresses, drought is one of the main factors limiting crop productivity and its impact is likely to increase under current scenarios of global climate change. We sought to determine to what extent wild common bean (Phaseolus vulgaris) exhibited adaptation to drought stress, whether this potential adaptation is dependent on the climatic conditions of the location of origin of indi...

Characterization of mouse pericardial fat: regulation by PAPP-A.

Although implicated in cardiovascular disease, little is known about the fat surrounding the heart. In humans, epicardial fat is the visceral fat depot of the heart, which directly contacts the myocardium. This strategically placed fat depot is thought to produce bioactive molecules that could affect cardiac function. A major limitation in understanding the biology of epicardial fat is its restricted access in humans and its seeming absence in commonly-used experimental animal models. Although laboratory mi...

Differential transcriptional profile through cell cycle progression in Arabidopsis cultures under simulated microgravity.

Plant cell proliferation is affected by microgravity during spaceflight, but involved molecular mechanisms, key for space agronomy goals, remain unclear. To investigate transcriptomic changes in cell cycle phases caused by simulated microgravity, an Arabidopsis immobilized synchronous suspension culture was incubated in a Random Positioning Machine. After simulation, a transcriptomic analysis was performed with two subpopulations of cells (G2/M and G1 phases enriched) and an asynchronous culture sample. Dif...

Consumption of Mediterranean versus Western Diet Leads to Distinct Mammary Gland Microbiome Populations.

Recent identification of a mammary gland-specific microbiome led to studies investigating bacteria populations in breast cancer. Malignant breast tumors have lower Lactobacillus abundance compared with benign lesions, implicating Lactobacillus as a negative regulator of breast cancer. Diet is a main determinant of gut microbial diversity. Whether diet affects breast microbiome populations is unknown. In a non-human primate model, we found that consumption of a Western or Mediterranean diet modulated mamm...

Shared molecular targets confer resistance over short and long evolutionary timescales.

Pre-existing and de novo genetic variants can both drive adaptation to environmental changes, but their relative contributions and interplay remain poorly understood. Here we investigated the evolutionary dynamics in drug-treated yeast populations with different levels of pre-existing variation by experimental evolution coupled with time-resolved sequencing and phenotyping. We found a doubling of pre-existing variation alone boosts the adaptation by 64.1% and 51.5% in hydroxyurea and rapamycin respectively....

Mucosal immune parameters, immune and antioxidant defence related genes expression and growth performance of zebrafish (Danio rerio) fed on Gracilaria gracilis powder.

In the present study zebrafish (Danio rerio) has been used as model organism to establish the effects of dietary supplementation of Gracilaria gracilis powder (GP) on mucosal and innate immune parameters, antioxidant enzymes, and growth. In order to establish these features, zebrafish were fed for eight weeks with experimental diets containing different levels of Red algae, 0.25, 0.5 and 1% of GP; also, a group was fed with control diet. At the end of the experimental period the antioxidant superoxide dismu...

In-Host Adaptation of Salmonella enterica Serotype Dublin during Prosthetic Hip Joint Infection.

Genome degradation has been central to the adaptation of Salmonella enterica serotypes to their hosts throughout evolution. We witnessed the patho-adaptation of a strain of Salmonella Dublin (a cattle-adapted serotype) to a human host during the course of a recurrent prosthetic hip joint infection evolving over several years.

Lower soluble Klotho and higher fibroblast growth factor 23 serum levels are associated with episodes of atrial fibrillation.

The proarrhythmic effect of fibroblast growth factor 23 (FGF23) was observed in patients with end stage kidney disease (ESKD). However, there is no data on the role of FGF23 and soluble Klotho (sKlotho) in the pathogenesis of atrial fibrillation (AF) beyond ESKD. The aim of the study was to assess the peripheral vein and left atrial (LA) serum levels of FGF23 and sKlotho along with calcium-phosphates parameters in patients with AF undergoing percutaneous radiofrequency pulmonary vein isolation (PVI).

Trafficking of Adhesion and Growth Factor Receptors and Their Effector Kinases.

Cell adhesion to macromolecules in the microenvironment is essential for the development and maintenance of tissues, and its dysregulation can lead to a range of disease states, including inflammation, fibrosis, and cancer. The biomechanical and biochemical mechanisms that mediate cell adhesion rely on signaling by a range of effector proteins, including kinases and associated scaffolding proteins. The intracellular trafficking of these must be tightly controlled in space and time to enable effective cell a...

Tissue Factor facilitates wound healing in human airway epithelial cells.

Tissue factor (TF) canonically functions as the initiator of the coagulation cascade. TF levels are increased in inflamed airways and appear to be important for tumor growth and metastasis. We hypothesized that airway epithelia release TF as part of a wound repair program.

Effects of oral zinc supplementation on zinc status and catch-up growth during the first 2 years of life in children with non-organic failure to thrive born preterm and at term.

We aimed to analyze the effect of oral zinc supplementation on serum insulin-like growth factor-1 (IGF-1) levels and catch-up growth in infants with non-organic failure to thrive (NOFTT) who were born preterm as compared to those born at term.

LRIG2 promotes the proliferation and cell cycle progression of glioblastoma cells in vitro and in vivo through enhancing PDGFRβ signaling.

The leucine‑rich repeats and immunoglobulin‑like domains (LRIG) gene family, comprising LRIG1, 2 and 3, encodes integral membrane proteins. It has been well established that LRIG1 negatively regulates multiple growth factor signaling pathways and is considered to be a tumor suppressor; however, the biological functions of LRIG2 remain largely unexplored. It was previously demonstrated that LRIG2 positively regulates epidermal growth factor receptor (EGFR) signaling, the most common aberrant receptor ty...

Distal tubule basolateral potassium channels: cellular and molecular mechanisms of regulation.

Multiple clinical and translational evidence support benefits of high potassium diet; however, there many uncertainties underlying the molecular and cellular mechanisms determining effects of dietary potassium. Kir4.1 and Kir5.1 proteins form a functional heteromer (Kir4.1/Kir5.1), which is the primary inwardly rectifying potassium channel on the basolateral membrane of both distal convoluted tubule (DCT) and the collecting duct principal cells. The purpose of this mini-review is to summarize latest advance...

Influence of the antiretroviral therapy on the growth pattern of children and adolescents living with HIV/AIDS.

Weight and height growth impairment is one of the most frequent manifestations in HIV-infected children and may be the first sign of disease, being considered a marker of disease progression and an independent risk factor for death. The aim of this review is to evaluate the influence of antiretroviral therapy on the growth pattern of children and adolescents living with HIV/AIDS.

The Neurobiology of Reduced Autobiographical Memory Specificity.

There has been a recent growth in investigations into the neural mechanisms underlying the problems recalling specific autobiographical events that are a core feature of emotional disorders. In this review we provide the first synthesis of this literature, taking into account brain as well as cognitive mechanisms. We suggest that these problems are driven by idiosyncratic activation in areas of the brain associated with assigning salience and self-relevance to emotional memories. Other areas associated with...

Mediterranean diet and platelet-activating factor; a systematic review.

Platelet-activating factor (PAF) is a glycerylether lipid and one of the most potent endogenous mediators of inflammation. Through its binding to a well-characterized receptor it initiates a plethora of cellular pro-inflammatory actions participating by this way to the pathology of most chronic diseases, including cardiovascular and renal diseases, CNS decline and cancer. Among the variety of prudent dietary patterns, Mediterranean Diet (MD) is the dietary pattern with the strongest evidence for its ability...

Body height in pediatric IBD: a structural equation model analysis.

Linear growth restriction is a unique feature of pediatric inflammatory bowel diseases (IBD) and reduced insulin-like growth factor (IGF-1) is a major determinant of short stature. We aimed to assess factors influencing somatic height in children suffering from IBD.

Growth Hormone Deficiency in the Transition Age.

Growth hormone (GH) is essential not only for normal growth during childhood, but also for the acquisition of bone mass and muscle strength in both sexes. This process is completed after the achievement of adult height in the phase of transition from adolescence to adulthood. Adolescents with childhood onset GH deficiency (GHD) show reduction of bone mineral density, decrease in lean body mass, increase in fat mass, and deterioration of the lipid profile. For this reason, continuation of GH replacement ther...
