Motor coordination and academic performance in primary school students

Objective: There is interest in studying the relationship between cognition and motor skills for decades. However, there are few studies that provide scientific evidence on the relationship between motor coordination and academic performance. Therefore, a descriptive cross-sectional study was conducted with 163 Spanish schoolchildren aged 6-9 years. Motor coordination was measured with the GRAMI-2 Test. Academic performance was obtained through the average grades of the subjects of language, mathematics, natural science, social science, English and artistic. The variables were calculated: motor coordination index and overall academic performance. The results obtained showed that schoolchildren with a better motor coordination index had higher marks in language, mathematics, natural science and English (p between <.01 and <.05). Dividing the sample according to the global academic performance, those with a good academic performance showed a better coordination performance in lateral jumps (p = .021) and a better motor coordination index (p = .008). These results indicate the existence of a positive relationship between motor coordination and academic performance, which may be this bidirectional link. This study could have practical implications to be taken into account by physical education teachers, such as, the increase in opportunities for physical activity during school and after school hours through the development of programs based on coordinative exercise, and especially oriented towards those less competent at the motor level

Not all autoantibodies are clinically relevant. Classic and novel autoantibodies in Sjögren's syndrome : A critical review

Sjögren's syndrome (SjS) is a heterogeneous systemic disease. The abnormal responses to La/SSB and Ro/SSA of both B-cells and T-cells are implicated as well as others, in the destruction of the epithelium of the exocrine glands, whose tissue characteristically shows a peri-epithelial lymphocytic infiltration that can vary from sicca syndrome to systemic disease and lymphoma. Despite the appearance of new autoantibodies, anti-Ro/SSA is still the only autoantibody included in the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria and is used extensively as a traditional biomarker in clinical practice. The study and findings of new autoantibodies in SjS has risen in the previous decade, with a central role given to diagnosis and elucidating new aspects of SjS physiopathology, while raising the opportunity to establish clinical phenotypes with the goal of predicting long-term complications. In this paper, we critically review the classic and the novel autoantibodies in SjS, analyzing the methods employed for detection, the pathogenic role and the wide spectrum of clinical phenotypes

1D and 2D neutral particle patterning by dielectrophoretic forces on z-cut Fe:LiNbO3 crystals

1D and 2D patterning of uncharged micro- and nanoparticles via dielectrophoretic forces on photovoltaic z-cut Fe:LiNbO3 have been investigated for the first time. The technique has been successfully applied with dielectric micro-particles of CaCO3 (diameter d = 1-3 μm) and metal nanoparticles of Al (d = 70 nm). At difference with previous experiments in x- and y-cut, the obtained patterns locally reproduce the light distribution with high fidelity. A simple model is provided to analyse the trapping process. The results show the remarkably good capabilities of this geometry for high quality 2D light-induced dielectrophoretic patterning overcoming the important limitations presented by previous configurations

Predictors of Global Non-Motor Symptoms Burden Progression in Parkinson's Disease. Results from the COPPADIS Cohort at 2-Year Follow-Up

Malaltia de Parkinson; Símptomes no motors; ProgressióEnfermedad de Parkinson; Sintomas no motores; ProgresiónParkinson’s disease; Non-motor symptoms; ProgressionBackground and Objective: Non-motor symptoms (NMS) progress in different ways between Parkinson’s disease (PD) patients. The aim of the present study was to (1) analyze the change in global NMS burden in a PD cohort after a 2-year follow-up, (2) to compare the changes with a control group, and (3) to identify predictors of global NMS burden progression in the PD group. Material and Methods: PD patients and controls, recruited from 35 centers of Spain from the COPPADIS cohort from January 2016 to November 2017, were followed-up with after 2 years. The Non-Motor Symptoms Scale (NMSS) was administered at baseline (V0) and at 24 months ± 1 month (V2). Linear regression models were used for determining predictive factors of global NMS burden progression (NMSS total score change from V0 to V2 as dependent variable). Results: After the 2-year follow-up, the mean NMS burden (NMSS total score) significantly increased in PD patients by 18.8% (from 45.08 ± 37.62 to 53.55 ± 42.28; p < 0.0001; N = 501; 60.2% males, mean age 62.59 ± 8.91) compared to no change observed in controls (from 14.74 ± 18.72 to 14.65 ± 21.82; p = 0.428; N = 122; 49.5% males, mean age 60.99 ± 8.32) (p < 0.0001). NMSS total score at baseline (β = −0.52), change from V0 to V2 in PDSS (Parkinson’s Disease Sleep Scale) (β = −0.34), and change from V0 to V2 in NPI (Neuropsychiatric Inventory) (β = 0.25) provided the highest contributions to the model (adjusted R-squared 0.41; Durbin-Watson test = 1.865). Conclusions: Global NMS burden demonstrates short-term progression in PD patients but not in controls and identifies worsening sleep problems and neuropsychiatric symptoms as significant independent predictors of this NMS progression.This research was funded by Fundación Española de Ayuda a la Investigación en Parkinson y otras Enfermedades Neuro-degenerativa

I Can See You: Temporal Variation in Ant Aggressiveness Towards Herbivores under Continuous Provision of High- or Low-quality Food Sources

To reduce herbivory, plants bearing extrafloral nectaries interact with ants and attract them by providing food. As plant bodyguards, ants respond to the resource provision and, using their antennae, detect chemical messages from the host plants that help them to locate herbivores. Ants can also use their vision to explore the environment; however, information is lacking on how interactions between visual signs and the availability of extrafloral nectar affect ant aggressiveness near resources. We addressed the following question in this study: does the ants’ ability to visualize potential herbivores enhance their aggression under a constant provision of a high-quality food source? Using an experimental approach within the semiarid intertropical region of Tehuacan-Cuicatlán (Mexico), we manipulated the availability of food sources by constantly offering artificial nectaries on the shrub Prosopis laevigata (Fabaceae). Over two time periods (day and night), we tested how the presence of a high-quality food source affected ant aggressiveness to herbivores. Therefore, we offered dummy caterpillars and counted the number of marks left by enemy attacks. Overall the attack rate was extremely high: 84.25% of the dummy caterpillars were injured. Ants were responsible for 86.22% of the marks left by enemies, and their aggression increased during the day, especially towards caterpillars in trees with high-quality food sources. During the night, ants probably rely mostly on their antennae to detect potential herbivores; therefore, their ability to detect dummy caterpillars was greater during the day. We show that, besides nectar quality and availability, visualizing herbivores may enhance ant aggressiveness.

Efecto de la aplicación intrauterina de ozono sobre la migración de neutrófilos y la endometritis subclínica en ganado lechero

The objective was to determine whether an ozonized saline solution (O3SS) increases endometrial polymorphonuclear neutrophils (PMNN) (Exp 1) and to challenge the preventive effect of O3SS on subclinical endometritis (SCE) (Exp 2). In Exp 1, 38 primiparous Holstein cows were used. Cows with (WHM) and no history of postpartum metritis (NHM) were included; they were then divided into control (CTRL, saline solution) or O3SS (6.7 ± 0.3 ppm) subgroups. At 55 d postpartum, 50 ml of CTRL or O3SS was applied intrauterinely and at 48 h, the quantity of PMNN was recorded by endometrial cytology. In Exp 2, 26 primiparous NHM Holstein cows were used. The cows were randomly distributed in CTRL or O3SS. Two doses of 50 ml were administered with an interval of 7 d (first application 11.3 ± 0.4 d postpartum). At d 30 postpartum, SCE (≥6 % PMNN) was diagnosed. WHM cows had higher numbers of endometrial PMNN compared to NHM cows (13.9 ± 6.2 vs 1.0 ± 0.46, P0.05) and the NHM-CTRL and NHM-O3SS groups (0.1 ± 0.1 and 1.8 ± 4.8, P>0.05) were not different. A statistical trend (P=0.09) of lower percentage of SCE was observed in the CTRL group compared to O3SS (15.4 and 46.2 %, respectively). In conclusion, transcervical O3SS does not increase the number of endometrial PMNN and preventive treatment with O3SS applied to NHM cows did not decrease SCE. The results suggest a possible anti-inflammatory effect of the ionized saline solution treatment.El objetivo fue determinar si una solución salina ozonizada (SSO3) incrementa los neutrófilos polimorfonucleares (NPMN) endometriales (Exp 1) y desafiar el efecto preventivo de SSO3 sobre la endometritis subclínica (ESC) (Exp 2). En el Exp 1 se utilizaron 38 vacas Holstein primíparas. Se incluyeron vacas con (CAM) y sin antecedentes de metritis postparto (SAM); posteriormente se repartieron en subgrupos control (CTRL, solución salina) o SSO3 (6.7 ± 0.3 ppm). A los 55 días postparto se aplicó 50 ml de CTRL o SSO3 intrauterinamente y a las 48 h se registró la cantidad de NPMN por citología endometrial. En el Exp 2 se utilizaron 26 vacas Holstein primíparas SAM. Las vacas se repartieron aleatoriamente en CTRL o SSO3. Se administraron dos dosis de 50 ml con intervalo de 7 días (primera aplicación 11.3 ± 0.4 días postparto). Al día 30 postparto se diagnosticó ESC (≥6% NPMN). Las vacas CAM tuvieron mayor número de NPMN endometriales comparado con vacas SAM (13.9 ± 6.2 vs 1.0±0.46, P0.05) y SAM-CTRL y SAM-SSO3 (0.1 ± 0.1 y 1.8 ± 4.8, P>0.05) no fueron diferentes. Se observó una tendencia estadística (P=0.09) de menor porcentaje de ESC en grupo CTRL comparado con SSO3 (15.4 y 46.2 %, respectivamente). En conclusión, la SSO3 por vía transcervical no incrementa el número de NPMN endometriales y el tratamiento preventivo con SSO3 aplicado a vacas SAM no disminuyó la ESC. Los resultados sugieren un posible efecto antiinflamatorio del tratamiento solución salina ionizada

Yield, sensory and proximate analysis of Dormitator latifrons fillets prepared with different cooking methods

Objective: To evaluate the effect of four cooking methods (steaming, griddling, baking or pan-frying) on the carcass and fillet yield and on the degree of sensory acceptance and proximate composition of fillets from Dormitator latifrons. Design/methods/approach: Whole and gutted fish, and the fillets cut from them, were weighed to determine yield. The fillets were cooked by steaming, griddling, baking or pan-frying according local traditional methods. The organoleptic characteristics (color, odor, general appearance, taste, texture, and juiciness) were evaluated using a 5-point hedonic scale. The proximate analysis was done on raw and cooked fish samples. Results: The average weight of the fish was 446.0 ± 63.4 g, with a carcass yield of 83.0% and a fillet yield of 18.7%. The organoleptic characteristics did not show significant differences, with all treatments obtaining average scores above 4 (like) in the hedonic scale. Regarding the proximate composition, the protein and ash content of the fish fillets increased with most of the cooking methods. The highest lipid content was obtained with the frying method. Limitations/implications: The evaluation of nutritional quality was done at the proximate level only¸ since it was considered that the protein nutritional quality (fillet protein), would not be modified substantially. Findings/conclusions: All four cooking methods were associated with a high level of acceptance and good nutritional quality, although the increase in lipid content of fried fish could have a detrimental effect on consumer health, in the case of a high level of consumption.
