The Integration Of Neuro-Linguistic Programming For Optimal Soccer Performance In Portugal

The subject of this article is integrating neuro-linguistic programming (NLP) approaches to improve football play in Portugal. The research aims to determine the integration of neuro-linguistic programming for optimal soccer performance in Portugal. The psychological discipline of NLP, which emphasises the relationship between language, behaviour patterns, and goal achievement, provides practical methods for improving players' mental toughness and all-around on-field performance. The research was based on primary data analysis to determine the data using SPSS software and generate results, including descriptive statistics, correlation coefficient analysis, chi-square analysis and regression analysis. Neuro-linguistic programming is the main independent variable, and optimal soccer performance is the main dependent variable. Using visualization, anchoring, language patterns, goal planning, and stress management strategies, athletes may cultivate a strong mental structure that facilitates optimal abilities. Coaches greatly aid NLP techniques and offer direction and encouragement to enable players to reach their greatest potential. Portuguese football teams can gain a competitive edge by adopting NLP, which promotes a positive culture, efficient communication, and a sense of shared objectives among players. Overall, the research found a positive and significant relationship between them. The possibility of incorporating NLP into football training and performance in Portugal is highlighted in this research, which might help build well-rounded athletes who possess exceptional physical and psychological qualities.

Can the post-ruminal urea release impact liver metabolism, and nutritional status of beef cows at late gestation?

We aimed to evaluate the effects of post-ruminal supply of urea (PRU) on nutritional status, and liver metabolism of pregnant beef cows during late gestation. Twenty-four Brahman dams, pregnant from a single sire, and weighing 545 kg ± 23 kg were confined into individual pens at 174 ± 23 d of gestation, and randomly assigned into one of two dietary treatments up to 270 d of gestation: Control (CON, n = 12), consisting of a basal diet supplemented with conventional urea, where the cows were fed with diets containing 13.5 g conventional urea per kg dry matter; and PRU (PRU, n = 12), consisting of a basal diet supplemented with a urea coated to extensively prevent ruminal degradation while being intestinally digestible, where the cows were fed with diets containing 14,8 g urea protected from ruminal degradation per kg dry matter. Post-ruminal supply of urea reduced the urine levels of 3-methylhistidine (P = 0.02). There were no differences between treatments for dry matter intake (DMI; P = 0.76), total digestible nutrient (TDN) intake (P = 0.30), and in the body composition variables, such as, subcutaneous fat thickness (SFT; P = 0.72), and rib eye area (REA; P = 0.85). In addition, there were no differences between treatments for serum levels of glucose (P = 0.87), and serum levels of glucogenic (P = 0.28), ketogenic (P = 0.72), glucogenic, and ketogenic (P = 0.45) amino acids, neither for urea in urine (P = 0.51) as well as urea serum (P = 0.30). One the other hand, enriched pathways were differentiated related to carbohydrate digestion, and absorption, glycolysis, pyruvate metabolism, oxidative phosphorylation, pentose phosphate pathway, and biosynthesis of amino acids of the exclusively expressed proteins in PRU cows. Shifting urea supply from the rumen to post-ruminal compartments decreases muscle catabolism in cows during late gestation. Our findings indicate that post-ruminal urea supplementation for beef cows at late gestation may improve the energy metabolism to support maternal demands. In addition, the post-ruminal urea release seems to be able to trigger pathways to counterbalance the oxidative stress associated to the increase liver metabolic rate.

Hibiscus acetosella: An Unconventional Alternative Edible Flower Rich in Bioactive Compounds.

The interest in the consumption of edible flowers has increased since they represent a rich source of bioactive compounds, which are significantly beneficial to human health. The objective of this research was to access the bioactive compounds and antioxidant and cytotoxic properties of unconventional alternative edible flowers of Hibiscus acetosella Welw. Ex Hiern. The edible flowers presented pH value of 2.8 ± 0.00, soluble solids content of 3.4 ± 0.0 °Brix, high moisture content of about 91.8 ± 0.3%, carbohydrates (6.9 ± 1.2%), lipids (0.90 ± 0.17%), ashes (0.4 ± 0.0%), and not detectable protein. The evaluation of the scavenging activity of free radicals, such as 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), of the flower extract was better than the results observed for other edible flowers (507.8 ± 2.7 µM TE and 783.9 ± 30.8 µM TE, respectively) as well as the total phenolic composition (TPC) value (568.8 ± 0.8 mg GAE/g). These flowers are rich in organic acids and phenolic compounds, mainly myricetin, and quercetin derivatives, kaempferol, and anthocyanins. The extract showed no cytotoxicity for the cell lineages used, suggesting that the extract has no directly harmful effects to cells. The important bioactive compound identified in this study makes this flower especially relevant in the healthy food area due to its nutraceutical potential without showing cytotoxicity.

Immunomodulatory activity of trifluoromethyl arylamides derived from the SRPK inhibitor SRPIN340 and their potential use as vaccine adjuvant.

The serine/arginine-rich protein kinases (SRPK) specifically phosphorylate their substrates at RS-rich dipeptides, which are abundantly found in SR splicing factors. SRPK are classically known for their ability to affect the splicing and expression of gene isoforms commonly implicated in cancer and diseases associated with infectious processes. Non-splicing functions have also been attributed to SRPK, which highlight their functional plasticity and relevance as therapeutic targets for pharmacological intervention. In this sense, different SRPK inhibitors have been developed, such as the well-known SRPIN340 and its derivatives, with anticancer and antiviral activities. Here we evaluated the potential immunomodulatory activity of SRPIN340 and three trifluoromethyl arylamide derivatives. In in vitro analysis with RAW 264.7 macrophages and primary splenocytes, all the compounds modulated the expression of immune response mediators and antigen-presentation molecules related to a tendency for M2 macrophage polarization. Immunization experiments were carried out in mice to evaluate their potential as vaccine immunostimulants. When administrated alone, the compounds altered the expression of immune factors at the injection site and did not produce macroscopic or microscopic local reactions. In addition, when prepared as an adjuvant with inactivated EHV-1 antigens, all the compounds increased the anti-EHV-1 neutralizing antibody titers, a change that is consistent with an increased Th2 response. These findings demonstrate that SRPIN340 and its derivatives exhibit a noticeable capacity to modulate innate and adaptative immune cells, disclosing their potential to be used as vaccine adjuvants or in immunotherapies.

The effect of Spondias mombin L. against Strongyloides venezuelensis: An in vitro approach.

Strongyloidiasis is a neglected tropical disease mainly caused by the nematode parasite Strongyloides stercoralis. Current treatment consists in the administration of ivermectin or, alternatively, albendazole (or analogues). Concerns regarding these drugs' irregular cure rates and side effects, raise a need for therapeutic alternatives. In this study, we tested the in vitro effect of Spondias mombin L. ethanolic extract against the laboratory model for strongyloidiasis, Strongyloides venezuelensis. The ethanolic extract was further fractionated and each fraction was also tested. Tested fractions were analyzed through thin layer chromatography and gas chromatography (GC/MS). Our results showed that S. mombin extract and fractions had a better in vitro effect than ivermectin, particularly fraction 4 which showed the better results causing 100% mortality in 4 h after exposure to an extract concentration of 400 µg/mL of RPMI medium and caused 100% mortality 12 h after exposure to an extract concentration of 50 µg/mL. Scanning electron microscopy showed that this fraction caused both wrinkling and peeling of the parasites cuticle, whilst ivermectin only caused wrinkling. GC/MS showed a high percentage of monoaromatic phenolic lipids (3-R phenol and 3-R1 phenol), which were likely responsible for the anti-Strongyloides effect. The use of polyvinylpyrrolidone reduced the efficiency, thus raising a need for alertness when using this excipient. Our results suggest that S. mombin is a potential source of compounds that could be used for stongyloidiasis treatment.

Proteomic Analysis of Liver from Finishing Beef Cattle Supplemented with a Rumen-Protected B-Vitamin Blend and Hydroxy Trace Minerals.

Vitamin B and trace minerals are crucial molecular signals involved in many biological pathways; however, their bioavailability is compromised in high-producing ruminant animals. So far, studies have mainly focused on the effects of these micronutrients on animal performance, but their use in a rumen-protected form and their impact on liver metabolism in finishing beef cattle is poorly known. We used a shotgun proteomic approach combined with biological network analyses to assess the effects of a rumen-protected B-vitamin blend, as well as those of hydroxy trace minerals, on the hepatic proteome. A total of 20 non-castrated Nellore males with 353 ± 43 kg of initial body weight were randomly assigned to one of the following treatments: CTRL-inorganic trace minerals without supplementation of a protected vitamin B blend, or SUP-supplementation of hydroxy trace minerals and a protected vitamin B blend. All animals were fed the same amount of the experimental diet for 106 days, and liver biopsies were performed at the end of the experimental period. Supplemented animals showed 37 up-regulated proteins (p < 0.10), and the enrichment analysis revealed that these proteins were involved in protein folding (p = 0.04), mitochondrial respiratory chain complex I (p = 0.01) and IV (p = 0.01), chaperonin-containing T-complex 2 (p = 0.01), glutathione metabolism (p < 0.01), and other aspects linked to oxidative-stress responses. These results indicate that rumen-protected vitamin B and hydroxy trace mineral supplementation during the finishing phase alters the abundance of proteins associated with the electron transport chain and other oxidation-reduction pathways, boosting the production of reactive oxygen species, which appear to modulate proteins linked to oxidative-damage responses to maintain cellular homeostasis.

Nonalcoholic Wernicke-Korsakoff Syndrome Resulting From Psychosis.

ABSTRACT: Wernicke encephalopathy (WE) results from thiamine deficiency. If undiagnosed or inadequately treated, WE evolves into Korsakoff syndrome (KS). We herein report a case of nonalcoholic Wernicke-Korsakoff syndrome (WKS) that resulted from malnutrition due to psychosis in a 42-years-old male patient. Thiamine deficiency was secondary to severe malnourishment due to poisoning delusions and daily life disorganization in a patient with previously unrecognized schizophrenia. Besides the presence of WE's classic triad of signs, brain magnetic resonance imaging showed also typical thalamic lesions. Furthermore, the patient also presented anterograde and retrograde amnesia, executive dysfunction, and confabulations, compatible with KS being already present. Intravenous treatment with thiamine was given for 37 days. Improvement in cognitive functions and brain imaging alterations was evident. Nevertheless, persistent WKS deficits were present. This case highlights the multiplicity of etiologies of WKS, namely, psychiatric, and its debilitating consequences if not promptly recognized and treated.

Effects of enrofloxacin treatment on the bacterial microbiota of milk from goats with persistent mastitis.

Antibiotic resistance has become a major concern for human and animal health. As fluoroquinolones have been extensively used in human and veterinary medicine, there has also been the rapid emergence and spread of antimicrobial resistance around the world. Here, we analysed the microbiome of goat milk using samples from healthy goats and those diagnosed with persistent mastitis and treated using the antibiotic enrofloxacin with 16S rRNA amplicon sequencing. We selected a group of 11 goats and 22 samples of milk that did not respond clinically to enrofloxacin treatment. Milk samples were evaluated before and after treatment to verify changes of the microbiota; the three first lactating goats were selected from the healthy control group. The milk samples from the healthy control animals presented a larger abundance of different species of bacteria of the Staphylococcus genus, but a smaller number of different genera, which indicated a more specific niche of resident bacteria. The Firmicutes phylum was predominantly different between the studied groups. Samples from before-treatment animals had a higher number of new species than those from the control group, and after being treated again. These microbiota received new bacteria, increasing the differences in bacteria even more in relation to the control group. Genotypes such as Trueperella and Mannheimia, between other genera, had a high abundance in the samples from animals with persistent mastitis. The dysbiosis in this study, with marked evidence of a complex microbiota in activity in cases of the failure of antimicrobial treatment for persistent chronic mastitis, demonstrates a need to improve the accuracy of pathogen identification and increases concern regarding antibiotic treatments in milk production herds.

Yacon production at different planting seasons and growing environments / Produção de yacon em diferentes estações de plantio e ambientes de cultivo

Yacon is a functional food with great potential for horticultural exploitation and its cultivation demands the generation of agronomic information. To address these needs, this study was performed to evaluate the production of yacon planted in different planting seasons under two growing conditions in Brazil. The experiments were conducted in two different locations, one in the mountain region (tropical microclimate at altitude with milder temperatures) and the other in the lowland region (warm tropical microclimate with higher temperatures). At both sites, yacon was planted in four seasons: autumn (April), winter (July), spring (September) and summer (December). At harvest, the tuberous roots were evaluated for leaf area index and the variables of vegetative development and productivity of plants (for total and standard commercial roots). It was concluded that yacon cultivation in mountain conditions (tropical climate with milder temperature) promotes the development and production of yacon. Additionally, planting in the autumn for both growing conditions (mountain or lowland) promotes the development and production of yacon, including increased production of roots of better commercial grade, allowing greater economic profitability. These results indicate that temperature has an influence on the growth and yield of the tuberous roots of yacon, and milder temperatures were more favourable.

A yacon é um alimento funcional com grande potencial para exploração hortícola e seu cultivo exige a geração de informações agronômicas. Para atender a essas necessidades, este estudo foirealizado com o objetivo de avaliar a produção de yacon plantada em diferentes estações de plantio sob duas condições de crescimento no Brasil. Os experimentos foram conduzidos em dois locais diferentes, um em região montanhosa (microclima tropical de altitude com temperaturas mais amenas) e o outro em região de baixada (microclima tropical quente com temperaturas mais elevadas). Em ambos os locais, a yacon foi plantada em quatro estações: outono (abril), inverno (julho), primavera (setembro) e verão (dezembro). Por ocasião da colheita das raízes tuberosas foram avaliados o índice de área foliar e variáveis de desenvolvimento vegetativo e produtividade das plantas (raízes tuberosas totais e por padrão). Concluiu-se que o cultivo de yacon em condições de montanha (clima tropical com temperatura mais suave) promove melhor desenvolvimento e produção de yacon. Além disso, plantar no outono para ambas as condições de crescimento (montanha ou baixada) promove melhor desenvolvimento e produção de yacon, incluindo o aumento da produção de raízes tuberosas de melhor qualidade comercial, permitindo maior rentabilidade econômica. Estes resultados indicam que a temperatura influenciou o crescimento e o rendimento das raízes tuberosas de yacon e as temperaturas mais amenas foram mais favoráveis.

The Perfect Storm: A Case of Non-Uremic Calciphylaxis.

Calciphylaxis is a severe condition associated with chronic kidney disease. We describe a rare case of non-uremic calciphylaxis in a 79-year-old woman with prosthetic aortic and mitral valves, chronic kidney disease and anaemia, who presented with painful skin lesions on her left leg. She was taking warfarin, calcium and iron supplements, and had been recently diagnosed with oligoarthritis and started on prednisolone, all factors associated with calciphylaxis. Despite treatment, the lesions rapidly progressed to large ulceration and sepsis, and pain management was challenging. Calciphylaxis was confirmed following a second skin biopsy but the patient died from septic shock and multi-organ failure. This case highlights the challenges associated with the diagnosis and treatment of calciphylaxis despite a high level of suspicion. LEARNING POINTS: The number of reported cases of calciphylaxis, once considered very rare, is increasing.Physicians should be aware of new information concerning the condition.Treatment includes a low antibiotic threshold, comprehensive pain management and efficient wound care.

The polysaccharide-rich tea of Ximenia americana barks prevents indomethacin-induced gastrointestinal damage via neutrophil inhibition.

ETHNOPHARMACOLOGICAL RELEVANCE: Barks of Ximenia americana are used by the population to treat gastrointestinal inflammatory disorders. Indomethacin is a non-selective non-steroidal anti-inflammatory drug that induces marked gastrointestinal damage. AIMS OF THE STUDIES: To evaluate the gastroprotective activity of total polysaccharides contained in the extract (TPL-Xa) or tea (Tea-Xa) of Ximenia americana barks in the mice gastric damage induced by indomethacin. MATERIALS AND METHODS: TPL-Xa was obtained by a combination of NaOH extraction and ethanol precipitation. Tea-Xa was prepared in distilled water boiled during 5 min. Animals received p.o. 0.9% NaCl (saline - control group), TPL-Xa (1-90 mg/kg) or Tea-Xa 1 h before gastritis induction by indomethacin (20 mg/kg). Mice were sacrificed 7 h after gastritis induction and analyzed for the following parameters: stomach lesions measurement; histological evaluation; myeloperoxidase (MPO) activity; nitrate/nitrite and cytokine levels; leukocyte adhesion and rolling by intravital microscopy. RESULTS: TPL-Xa reduced macroscopic and microscopic damage, MPO activity (59%), leukocyte rolling (86%) and adhesion (84%), nitrite/nitrate ratio (100%) and IL-8 (69%), but increased IL-4 (50%). Tea-Xa (12.8 yield; 39.3% carbohydrate, including 25.8% uronic acid; 4% protein) reduced macroscopic damage (62%) and MPO activity (50%). CONCLUSION: TPL and Tea of Ximenia americana barks ameliorate the gastric injury induced by indomethacin in mice, an effect that was dependent on the reduction of neutrophil infiltration.

Schistosoma mansoni: In vivo evaluation of Phyllanthus amarus hexanic and ethanolic extracts.

Human schistosomiasis is an important neglected tropical disease caused by blood flukes of the genus Schistosoma and is responsible for more than 280,000 deaths annually. Treatment for this disease relies currently on a single drug, praziquantel (PZQ). Concerns regarding PZQ resistance and insensitivity of juvenile schistosomes have increased the interest in resorting to medicinal plants for alternative drug therapies. This study aimed to perform an in vivo schistosomicidal activity evaluation of crude hexanic (HE) and ethanolic (EE) extracts obtained from Phyllanthus amarus in mice infected with Schistosoma mansoni (BH strain). Mice were treated orally with a single dose of 100 or 250 mg/kg, on two different infection periods, 30 and 45 days post-infection (dpi). Parameters such as worm recovery, faecal egg count, intestinal tissue egg count and liver histopathology were evaluated. Treatment against young adult (30 dpi) and adult (45 dpi) worms were more effective compared to the control group treated with PZQ. At a concentration of 250 mg/kg (30 dpi) EE showed a 54.4% female reduction and a 61.2% total worm reduction whilst at a concentration of 100 mg/kg (45 dpi) HE showed a 40.6% female worm reduction and a 45.3% total worm reduction. Histopathological examination showed a granuloma decrease in both number and size for groups treated with 250 mg/kg of HE (45 dpi) or EE (30 or 45 dpi). From these results, it can be concluded that both hexanic and ethanolic extracts have antischistosomal activities, however, act differently according to the parasites age. The schistosomicidal activity results in groups treated 30 days post infection is extremely important since praziquantel does not show activity against the juvenile forms of Schistosoma.

Anti-helminthic activity of Momordica charantia L. against Fasciola hepatica eggs after twelve days of incubation in vitro.

Fasciolosis, a parasitic disease caused by the trematode Fasciola hepatica underreported is expanding both in human and animal population, throughout the world. The constant use of synthetic drugs to treat this condition has led to the natural selection of resistant strains of the parasite. Hence, there is a growing focus on the potential anti-helminthic properties of medicinal plants and phytopharmaceuticals. The current study assessed the potential anti-fasciolicide action of Momordica charantia leaf extracts and fractions on the eggs of F. hepatica parasites. The lyophilized crude extract (CE) of M. charantia leaves and its sub-fractions, obtained from liquid-liquid partitioning with organic solvents, were analysed by High Performance Liquid Chromatography (HPLC), suspended in 1% DMSO and used in in vitro tests. Quadruplicates of 50F. hepatica eggs were incubated at 23°C with M. charantia leaf CE in different concentrations. After 12days no larvae were formed in eggs incubated with CE concentrations above 12.5mg/mL. Eggs incubated with CE sub-fractions at concentrations of 1000, 100, 10, 1, 0.1, 0.01µg/mL affected embryonic development, with n-butanol presenting the strongest inhibition of miracidia formation. In contrast, on the 12th day, 90% of the miracidia hatched in the control experiments using 0.03% DMSO whereas embryogenesis was completely abolished with any concentration of albendazole sulphoxide ABZ(SO). Chemical analysis of the CE and sub-fractions revealed a prominent presence of flavonoids. HPLC-MS confirmed Quercetin to be one of the main flavonoids present in the CE and the n-butanol subfraction. This is the first study to analyse the potential anti-fasciolicide action of M. charantia leaf CE and subfractions.
