Differential effects of plant and animal fats on obesity-induced dyslipidemia and atherosclerosis in Ldlr-/-.Leiden mice.

Cardiovascular disease (CVD) is closely associated with obesity through risk factors such as dyslipidemia and chronic low-grade inflammation, which may be affected by diet. Dietary fats have been extensively studied in relation to CVD risk, however these studies have not always yielded consistent results, most likely due to lack in control of experimental conditions and confounding factors. Here we studied the effects of different plant and animal fats on dyslipidemia, inflammation, and atherosclerosis. Ldlr-/-.Leiden mice were fed isocaloric energy-dense diets with translational macronutrient composition for 28 weeks. The diets were identical apart from the type of fat they contained: either (1) a mixture of olive and rapeseed oil, (2) sunflower oil, (3) pork fat, (4) beef fat, or (5) milk fat. The fatty acid composition of the diets was determined and effects on circulating lipid and inflammatory risk factors and atherosclerosis were examined, complemented by adipose tissue histology and liver transcriptomics. While visceral fat mass, adipocyte size, and adipose tissue inflammation were not differentially affected by the diets, atherosclerotic lesion load and severity was more pronounced with increasing dietary saturated fatty acid content and decreasing monounsaturated and polyunsaturated fatty acid content, and hence most pronounced with beef and milk fat. These differential effects were accompanied by increases in pro-atherogenic plasma lipids/lipoproteins (e.g., triglycerides, apolipoprotein B), activation of pro-atherogenic cytokine/chemokine signaling pathways in liver, and with circulating pro-atherogenic mediators of inflammation altogether providing a rationale for the differential effects of plant and animal fats.

Clonal relationship, virulence genes, and antimicrobial resistance of Morganella morganii isolated from community-acquired infections and hospitalized patients: a neglected opportunistic pathogen.

Morganella morganii is a bacterium belonging to the normal intestinal microbiota and the environment; however, in immunocompromised individuals, this bacterium can become an opportunistic pathogen, causing a series of diseases, both in hospitals and in the community, being urinary tract infections more prevalent. Therefore, the objective of this study was to evaluate the prevalence, virulence profile, and resistance to antimicrobials and the clonal relationship of isolates of urinary tract infections (UTI) caused by M. morganii, both in the hospital environment and in the community of the municipality of Londrina-PR, in southern Brazil, in order to better understand the mechanisms for the establishment of the disease caused by this bacterium. Our study showed that M. morganii presents a variety of virulence factors in the studied isolates. Hospital strains showed a higher prevalence for the virulence genes zapA, iutA, and fimH, while community strains showed a higher prevalence for the ireA and iutA genes. Hospital isolates showed greater resistance compared to community isolates, as well as a higher prevalence of multidrug-resistant (MDR) and extended-spectrum beta lactamase (ESBL)-producing isolates. Several M. morganii isolates from both sources showed high genetic similarity. The most prevalent plasmid incompatibility groups detected were FIB and I1, regardless of the isolation source. Thus, M. morganii isolates can accumulate virulence factors and antimicrobial resistance, making them a neglected opportunistic pathogen.

Green-Synthesized Silver Nanoparticles in the Prevention of Multidrug-Resistant Proteus mirabilis Infection and Incrustation of Urinary Catheters BioAgNPs Against P. mirabilis Infection.

This study aimed to assess the activity of AgNPs biosynthesized by Fusarium oxysporum (bio-AgNPs) against multidrug-resistant uropathogenic Proteus mirabilis, and to assess the antibacterial activity of catheters coated with bio-AgNPs. Broth microdilution and time-kill kinetics assays were used to determine the antibacterial activity of bio-AgNPs. Catheters were coated with two (2C) and three (3C) bio-AgNPs layers using polydopamine as crosslinker. Catheters were challenged with urine inoculated with P. mirabilis to assess the anti-incrustation activity. MIC was found to be 62.5 µmol l-1, causing total loss of viability after 4 h and bio-AgNPs inhibited biofilm formation by 76.4%. Catheters 2C and 3C avoided incrustation for 13 and 20 days, respectively, and reduced biofilm formation by more than 98%, while the pristine catheter was encrusted on the first day. These results provide evidence for the use of bio-AgNPs as a potential alternative to combat of multidrug-resistant P. mirabilis infections.

Water quality monitoring in southern Brazil and the assessment of risk factors related to contamination by coliforms and Escherichia coli.

The potability of water, including underground sources, is constantly affected by human activities. To assess water quality and water security in rural and urban areas of southern Brazil, a quantitative, retrospective analysis of water samples collected monthly by the Brazilian health authorities (19,687 samples from 2013 to 2021) was performed. In rural areas, 5,979 water samples (77.54%) were found to be contaminated by coliform bacteria and 3,431 (44.50%) by Escherichia coli. In addition, 1,616 (20.95%) of the contaminated samples were significantly correlated with rainfall amount. In urban areas, 1,268 (10.95%) of the samples contained coliform bacteria and 293 (2.53%) of these samples contained E. coli, with the factor of rainfall associated with 1,081 samples (9.33%) with bacterial contamination. In terms of physicochemical parameters, turbidity exceeded the national standard (5 uT) in 448 (2.32%) samples and fluoride fell below the required level (0.8 mg/L) in 106 samples (0.54%). The presence of free residual chlorine (0.2-2.0 mg/L) was verified in 846 samples (14.38%) in rural areas and in 10,825 samples (56.13%) in urban areas. These results suggest a strong association between rainfall factors and physicochemical alterations, as well as the risk of greater microbial contamination of water for human consumption.

A High-Fat Western Diet Attenuates Intestinal Changes in Mice with DSS-Induced Low-Grade Inflammation.

BACKGROUND: A Western diet (WD) is associated with increased inflammation in the large intestine, which is often ascribed to the high dietary fat content. Intestinal inflammation in rodents can be induced by oral administration of dextran sodium sulfate (DSS). However, most studies investigating effects of WD and DSS have not used appropriate low-fat diets (LFDs) as control. OBJECTIVES: To compare the effects of a WD with those of an LFD on colon health in a DSS-induced low-grade colonic inflammation mouse model. METHODS: Six-week-old male C57BL/6JRj mice were fed an LFD (fat = 10.3% energy, n = 24) or a WD (fat = 41.2% energy, n = 24) for 15 wk [Experiment 1 (Exp.1)]. Half the mice on each diet (n = 12) then received 1% DSS in water for 6 d with the remainder (n = 12 in each diet) administered water. Disease activity, proinflammatory genes, inflammatory biomarkers, and fecal microbiota (16S rRNA) were assessed (Exp.1). Follow-up experiments (Exp.2 and Exp.3) were performed to investigate whether fat source (milk or lard; Exp.2) affected outcomes and whether a shift from LFD to WD 1 d prior to 1% DSS exposure caused an immediate effect on DSS-induced inflammation (Exp.3). RESULTS: In Exp.1, 1% DSS treatment significantly increased disease score in the LFD group compared with the WD group (2.7 compared with 0.8; P < 0.001). Higher concentrations of fecal lipocalin (11-fold; P < 0.001), proinflammatory gene expression (≤82-fold), and Proteobacteria were observed in LFD-fed mice compared with the WD group. The 2 fat sources in WDs (Exp.2) revealed the same low inflammation in WD+DSS mice compared with LFD+DSS mice. Finally, the switch from LFD to WD just before DSS exposure resulted in reduced colonic inflammation (Exp.3). CONCLUSIONS: Herein, WDs (with milk or lard) protected mice against DSS-induced colonic inflammation compared with LFD-fed mice. Whether fat intake induces protective mechanisms against DSS-mediated inflammation or inhibits establishment of the DSS-induced colitis model is unclear.

Virulence, resistance and clonality of Proteus mirabilis isolated from patients with community-acquired urinary tract infection (CA-UTI) in Brazil.

Urinary tract infections (UTIs) are among the most common human infections, both in hospitals and in communities. Proteus mirabilis is known to cause community-acquired urinary tract infection (CA-UTI) and is an important causative agent of nosocomial UTIs. The pathogenesis of this species is related to its ability to manifest virulence factors, such as biofilms, adhesion molecules, urease, proteases, siderophores, and toxins. In this study, we investigated the virulence, sensitivity to antimicrobials, and clonal relationship of 183 strains isolated from the urine of CA-UTI patients in Londrina, Paraná State, Brazil. A total of 100% of the strains were positive for hpmA, ptA, zapA, mrpA, pmfA, ireA, and atfA virulence genes. The ucaA gene was positive in 81.4% of the cases. The strains showed high rates of sensitivity to the evaluated antimicrobials, and only one was ESBL-positive. All the tested bacteria showed the capacity to form biofilms: 73.2% had a very strong intensity, while 25.7% had a strong intensity, and 1.1% had a moderate intensity. Regarding clonality, 40 clonal clusters were found among the microorganisms tested. Our results showed that strains of P. mirabilis isolated from CA-UTI patients have several virulence factors. Although the urinary clinical isolates studied showed high sensitivity to antimicrobials, the strains showed a strong capacity to form biofilms, making antibiotic therapy difficult. In addition, it was observed that there were clones of P. mirabilis circulating in the city of Londrina.

Proteus mirabilis from community-acquired urinary tract infections (UTI-CA) shares genetic similarity and virulence factors with isolates from chicken, beef and pork meat.

Proteus mirabilis is an opportunistic pathogen associated with a variety of infections in humans, especially those in the urinary tract. The isolation of this pathogen in foods of animal origin such as meat is poorly documented and should not be neglected, in view of the zoonotic risk that this can pose to human health. Thus, the objective of this study was to evaluate the prevalence, virulence profile, and similarity between P. mirabilis strains isolated from chicken, beef, and pork meat and those causing community-acquired urinary tract infections (UTI-CA), in order to better understand the role of this bacterium as a zoonotic pathogen. P. mirabilis was isolated from the three types of meat and was found to be more prevalent in chicken. All isolates exhibited several genotypic and phenotypic virulence characteristics, such as adhesion capacity in HEp-2 cell culture, biofilm formation, cytotoxicity in Vero cells and genes that express fimbriae (mrpA, pmfA, ucaA, atfA), hemolysin (hpmA), proteases (zapA and ptA) and siderophore receptor (ireA). UTI-CA strains showed a higher prevalence of ucaA and ireA genes, whereas those from the chicken meat had a higher prevalence of the atfA gene compared with the isolates from the beef and pork meat. It was observed that chicken meat and UTI-CA strains mainly formed very strong biofilms, whereas strains isolated from beef and pork formed more weak and moderate biofilms. Several strains from meat showed close genetic similarity to those from UTI-CA and had the same virulence profiles. Thus, meats may be an important source of the dissemination of P. mirabilis responsible for causing UTIs in the community.

Intrahemispheric EEG: A New Perspective for Quantitative EEG Assessment in Poststroke Individuals.

The ratio between slower and faster frequencies of brain activity may change after stroke. However, few studies have used quantitative electroencephalography (qEEG) index of ratios between slower and faster frequencies such as the delta/alpha ratio (DAR) and the power ratio index (PRI; delta + theta/alpha + beta) for investigating the difference between the affected and unaffected hemisphere poststroke. Here, we proposed a new perspective for analyzing DAR and PRI within each hemisphere and investigated the motor impairment-related interhemispheric frequency oscillations. Forty-seven poststroke subjects and twelve healthy controls were included in the study. Severity of upper limb motor impairment was classified according to the Fugl-Meyer assessment in mild/moderate (n = 25) and severe (n = 22). The qEEG indexes (PRI and DAR) were computed for each hemisphere (intrahemispheric index) and for both hemispheres (cerebral index). Considering the cerebral index (DAR and PRI), our results showed a slowing in brain activity in poststroke patients when compared to healthy controls. Only the intrahemispheric PRI index was able to find significant interhemispheric differences of frequency oscillations. Despite being unable to detect interhemispheric differences, the DAR index seems to be more sensitive to detect motor impairment-related frequency oscillations. The intrahemispheric PRI index may provide insights into therapeutic approaches for interhemispheric asymmetry after stroke.

Interhemispheric asymmetry of the motor cortex excitability in stroke: relationship with sensory-motor impairment and injury chronicity.

OBJECTIVE: To compare the interhemispheric asymmetry of the motor cortex excitability of chronic stroke patients with healthy and to observe if the magnitude of this asymmetry is associated to sensory-motor impairment and stroke chronicity. METHODS: This cross-sectional study was performed with chronic stroke and aged and sex-matched healthy individuals. The interhemispheric asymmetry index was calculated by the difference of rest motor threshold (rMT) of the brain hemispheres. The rMT was assessed by transcranial magnetic stimulation over the cortical representation of the first dorsal interosseous muscle. To investigate the relationship of the asymmetry with sensory-motor impairment and injury chronicity, the stroke patients were grouped according to the level of sensory-motor impairment (mild/moderate, moderate/severe, and severe) and different chronicity stages (> 3-12, 13-24, 25-60, and > 60 months since stroke). RESULTS: Fifty-six chronic stroke and twenty-six healthy were included. We found higher interhemispheric asymmetry in stroke patients (mean, 27.1 ± 20.9) compared to healthy (mean, 4.9 ± 4.7). The asymmetry was higher in patients with moderate/severe (mean, 35.4 ± 20.4) and severe (mean, 32.9 ± 22.7) impairment. No difference was found between patients with mild/moderate impairment (mean, 15.5 ± 12.5) and healthy. There were no differences of the interhemispheric asymmetry between patients with different times since stroke (> 3-12, mean, 32 ± 18.1; > 13-24, mean, 20.7 ± 16.2; > 25-60, mean, 29.6 ± 18.1; > 60 months, mean, 25.9 ± 17.5). CONCLUSION: Stroke patients showed higher interhemispheric asymmetry of the motor cortex excitability when compared to healthy, and the magnitude of this asymmetry seems to be correlated with the severity of sensory-motor impairment, but not with stroke chronicity. SIGNIFICANCE: Higher interhemispheric asymmetry was found in stroke patients with greatest sensory-motor impairment.

Molecular and phenotypic characterization of diarrheagenic Escherichia coli isolated from groundwater in rural areas in southern Brazil.

Water-borne diseases like diarrheagenic Escherichia coli (DEC)-induced gastroenteritis are major public health problems in developing countries. In this study, the microbiological quality of water from mines and shallow wells was analyzed for human consumption. Genotypic and phenotypic characterization of DEC strains was performed. A total of 210 water samples was analyzed, of which 153 (72.9%) contained total coliforms and 96 (45.7%) E. coli. Of the E. coli isolates, 27 (28.1%) contained DEC genes. The DEC isolates included 48.1% Shiga toxin-producing E. coli (STEC), 29.6% enteroaggregative E. coli (EAEC), 14.9% enteropathogenic E. coli (EPEC), 3.7% enterotoxigenic E. coli (ETEC), and 3.7% enteroinvasive E. coli (EIEC). All the STECs had cytotoxic effects on Vero cells and 14.8% of the DEC isolates were resistant to at least one of the antibiotics tested. All DEC formed biofilms and 92.6% adhered to HEp-2 cells with a prevalence of aggregative adhesion (74%). We identified 25 different serotypes. One EPEC isolate was serotype O44037:H7, reported for the first time in Brazil. Phylogenetically, 63% of the strains belonged to group B1. The analyzed waters were potential reservoirs for DEC and could act as a source for infection of humans. Preventive measures are needed to avoid such contamination.

Sialometric and Sialochemical Changes in Morbidly Obese Patients before and after Bariatric Surgery.

AIM: To evaluate the sialometric and sialochemical changes in morbidly obese patients before and after bariatric surgery. MATERIALS AND METHODS: A total of 74 participants were divided into three groups paired by sex and age: (a) Experimental 1 (E1)-morbid obesity (n = 40)-according to the Fobi-Capella technique, corresponding to the individuals with a body mass index (BMI) of greater than 40 kg/m2 prior to bariatric surgery; (b) Experimental 2 (E2)-the same individuals after surgery; and (c) control (C) (n = 34)-individuals with a BMI of nearly 23 kg/m2. The measure of salivary flow was carried out by collecting stimulated saliva. The pH was evaluated using the pocket pH meter, while the salivary buffer capacity (SBC) was determined by the titration method. Analyses of the salivary concentration of total proteins (TPs), amylase activity, urea, calcium (Ca++), and glucose were evaluated using the calorimetric method. RESULTS: Group E1, as compared with group C, presented the highest pH levels (p = 0.03), amylase activity (p = 0.00), and calcium (p = 0.00). The opposite was observed for glucose (p = 0.00), TP (p = 0.04), and urea (p = 0.04). Group E2, as compared with group C, revealed higher levels of amylase (p = 0.00) and calcium (p = 0.00). The opposite was observed for SBC (p = 0.01), PT (p = 0.00), and glucose (p = 0.00). Group E1, as compared with group E2, presented higher values of SBC (p = 0.00) and urea (p = 0.00). The lowest values were found for calcium and urea (p = 0.03). CONCLUSION: Both weight gain and bariatric surgery are risk factors for the oral condition, causing change in some important salivary components, such as TP, amylase, calcium, and glucose. CLINICAL SIGNIFICANCE: This article is a valuable addition to the scientific literature, due to its novelty. There are no papers that show salivary alterations related to bariatric surgeries.

Cerebellar Transcranial Direct Current Stimulation (ctDCS) Impairs Balance Control in Healthy Individuals.

The cerebellum plays an important role in the planning, initiation and stability of movements, as well as in postural control and balance. Modulation of neural regions underlying balance control may be a potential alternative to treat balance impairments in cerebellar patients. Transcranial direct current stimulation (tDCS) is a noninvasive and safe tool capable to modulate cerebellar activity. We aim to investigate the effects of cerebellar tDCS (ctDCS) on postural balance in healthy individuals. Fifteen healthy and right-handed subjects were submitted to three sessions of ctDCS (anodal, cathodal and sham), separated by at least 48 h. In each session, tests of static (right and left Athlete Single Leg tests) and dynamic balance (Limits of Stability test) were performed using the Biodex Balance System before and immediately after the ctDCS. The results revealed that cathodal ctDCS impaired static balance of healthy individuals, reflected in higher scores on overall stability index when compared to baseline for right (p = 0.034) and left (p = 0.01) Athlete Single Leg test. In addition, we found significant impairment for left Athlete Single Leg test in comparison to sham stimulation (p = 0.04). As far as we know, this is the first study that points changes on balance control after ctDCS in healthy individuals. This finding raises insights to further investigation about cerebellar modulation for neurological patients.

Efficacy of Noninvasive Brain Stimulation on Pain Control in Migraine Patients: A Systematic Review and Meta-Analysis.

OBJECTIVE: To evaluate the efficacy of noninvasive brain stimulation (NIBS) on pain control in migraine patients. BACKGROUND: Recent studies have used NIBS as an abortive and prophylactic treatment for migraine; however, its efficacy regarding meaningful clinical effects remains to be critically analyzed. DESIGN: Systematic review of controlled clinical trials. METHODS: Searches were conducted in six databases: MEDLINE (via PubMed), LILACS (via BIREME), CINAHL (via EBSCO), Scopus (via EBSCO), Web of Science, and CENTRAL. Two independent authors searched for randomized controlled clinical trials published through until January 2016 that involved the use of transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) in migraineurs. Studies which met the eligibility criteria were assessed and methodological quality was examined using the Cochrane tool for assessing risk of bias. Information about pain intensity (primary outcome), migraine attacks, painkiller intake, and adverse effects were extracted. RESULTS: Eight studies were included in the quantitative analysis with 153 migraine patients that received NIBS and 143 sham NIBS. In overall meta-analysis, we did not find significant results for pain intensity (SMD: -0.61; CI: -1.35 to 0.13; P = .11), for migraine attacks (SMD: -0.44; 95%; CI: -1.15 to 0.26; P = .22), and for painkiller intake (SMD: -0.57; 95% CI: -1.21 to 0.07; P = .08). However, subgroup analysis considering only tDCS effects have demonstrated a decrease for pain intensity (SMD: -0.91; 95% CI: -1.79 to -0.03; P = .04), migraine attacks (SMD: -0.75; 95% CI: -1.25 to -0.24; P = .004), and painkiller intake (SMD: -0.64; 95% CI: -1.21 to -0.07; P = .03). Subgroup analysis for TMS did not reveal significant effects for any outcome. CONCLUSION: Low or very low quality of evidence suggests that our primary outcome evaluation failed to find support for the superiority of NIBS over sham treatment. Although, subgroup analysis reveals that tDCS have moderate to high effects and could be a promising nonpharmacological alternative to pain control, mainly for painkiller intake reduction. However, there is a need for larger controlled trials with methodological rigor, which could increase the power of result inference.

Physical activity helps to control music performance anxiety.

We evaluated if regular physical activity could influence musical performance anxiety (MPA) in college music students. Levels of MPA, as measured with the Kenny MPA Inventory, and a survey about the physical activity habits were obtained from 87 students of music. The results showed that physically active musicians had lower MPA scores (p<0.05) than non-active ones, independent of gender. We conclude that there is an association between physical activity and minor MPA, and studies with a longitudinal design should be done to explore this important issue.

Trans-spinal magnetic stimulation combined with kinesiotherapy as a new method for enhancing functional recovery in patients with spinal cord injury due to neuromyelitis optica: a case report.

BACKGROUND: Experimental studies have shown that repetitive trans-spinal magnetic stimulation (TsMS) decreases demyelination and enables recovery after spinal cord injury (SCI). However, the usefulness of TsMS in humans with SCI remains unclear. Therefore, the main objective of this study is to evaluate the effects of TsMS combined with kinesiotherapy on SCI symptoms. We describe a protocol treatment with TsMS and kinesiotherapy in a patient with SCI due to neuromyelitis optica (NMO)-associated transverse myelitis. CASE PRESENTATION: A 23-year-old white male with NMO spectrum disorders started symptoms in 2014 and included lumbar pain evolving into a mild loss of strength and sensitivity in both lower limbs. Five months later, the symptoms improved spontaneously, and there were no sensorimotor deficits. Two years later, in 2016, the symptoms recurred with a total loss of strength and sensitivity in both lower limbs. Initially, physiotherapy was provided in 15 sessions with goals of motor-sensory recovery and improving balance and functional mobility. Subsequently, TsMS (10 Hz, 600 pulses, 20-seconds inter-trains interval, at 90% of resting motor threshold of the paravertebral muscle) was applied at the 10th thoracic vertebral spinous process before physiotherapy in 12 sessions. Outcomes were assessed at three time points: prior to physiotherapy alone (T-1), before the first session of TsMS combined with kinesiotherapy (T0), and after 12 sessions of TsMS combined with kinesiotherapy (T1). The patient showed a 25% improvement in walking independence, a 125% improvement in balance, and an 18.8% improvement in functional mobility. The Patient Global Impression of Change Scale assessed the patient's global impression of change as 'much improved'. CONCLUSION: TsMS combined with kinesiotherapy may safely and effectively improve balance, walking independence, and functional mobility of patients with SCI due to NMO-associated transverse myelitis.

Genomic insights into a Proteus mirabilis strain inducing avian cellulitis.

Proteus mirabilis, a microorganism distributed in soil, water, and animals, is clinically known for causing urinary tract infections in humans. However, recent studies have linked it to skin infections in broiler chickens, termed avian cellulitis, which poses a threat to animal welfare. While Avian Pathogenic Escherichia coli (APEC) is the primary cause of avian cellulitis, few cases of P. mirabilis involvement are reported, raising questions about the factors facilitating such occurrences. This study employed a pan-genomic approach to investigate whether unique genes exist in P. mirabilis strains causing avian cellulitis. The genome of LBUEL-A33, a P. mirabilis strain known to cause this infection, was assembled, and compared with other P. mirabilis strains isolated from poultry and other sources. Additionally, in silico serogroup analysis was conducted. Results revealed numerous genes unique to the LBUEL-A33 strain. No function in cellulitis was identified for these genes, and in silico investigation of the virulence potential of LBUEL-A33's exclusive proteins proved inconclusive. These findings support that multiple factors are necessary for P. mirabilis to cause avian cellulitis. Furthermore, this species likely employs its own unique arsenal of virulence factors, as many identified mechanisms are analogous to those of E. coli. While antigenic gene clusters responsible for serogroups were identified, no clear trend was observed, and the gene cluster of LBUEL-A33 did not show homology with any sequenced Proteus serogroups. These results reinforce the understanding that this disease is multifactorial, necessitating further research to unravel the mechanisms and underpin the development of control and prevention strategies.

Cyberlindnera jadinii yeast as a functional protein source: Modulation of immunoregulatory pathways in the intestinal proteome of zebrafish (Danio rerio).

Yeasts contain bioactive components that can enhance fish immune robustness and disease resistance. Our study focused on analyzing intestinal immunoregulatory pathways in zebrafish (Danio rerio) using iTRAQ and 2D LC-MS/MS to quantify intestinal proteins. Zebrafish were fed either control diet (C) or diet supplemented with autolyzed Cyberlindnera jadinii (ACJ). KEGG analysis revealed that ACJ yeast diet induced increased abundance of proteins related to arginine and proline metabolism, phagosome, C-lectin receptor signaling, ribosome and PPAR signaling pathways, which can modulate and enhance innate immune responses. ACJ yeast diet also showed decreased abundance of proteins associated with inflammatory pathways, including apoptosis, necroptosis and ferroptosis. These findings indicate boosted innate immune response and control of inflammation-related pathways in zebrafish intestine. Our findings in the well annotated proteome of zebrafish enabled a detailed investigation of intestinal responses and provide insight into health-beneficial effects of yeast species C. jadinii, which is relevant for aquaculture species.

Peritoneal tuberculosis with an atypical presentation. Surgical case report.

INTRODUCTION AND IMPORTANCE: 1-3% of tuberculosis cases are extrapulmonary, which 11-16% are abdominal. In recent years, a progressive increase in the number of peritoneal tuberculosis cases has been observed. Peritoneal tuberculosis accounts for only 1-2% of all cases of peritonitis. Historically it is known as "the great mimicker" since it can resemble a neoplastic, infectious or inflammatory intestinal disease. The most common triad of presentation is fever, weight loss and abdominal pain; ascites is also usually present. For diagnosis, computed tomography is the most sensitive technique and is complemented by elevation of CA 125 and Adenosine deaminase (ADA) but is confirmed by pathology study. Treatment is the same as the pulmonary presentation. CASE PRESENTATION: A 33-year-old man presented with acute complication appendicitis. A limited right hemicolectomy was performed due to the nature of the patient advanced disease. Multiple small tumor resembling peritoneal implant and a granuloma were identified has sampled during the patient's surgical procedure. Pathologic examination revealed peritoneal tuberculosis and medical therapy was initiated. Laboratory assays including CA 125 and adenosine deaminase (ADA) can be useful serum markers to follow during treatment if they are positive. DISCUSSION: The most common presentation of peritoneal tuberculosis is fever, weight loss and abdominal pain. Our patient did not have any of these symptoms, we founded granulomas in surgery of intestinal restitution. METHODS: The work has been reported in line with the SCARE criteria. CONCLUSIONS: This pathology should always be kept in mind as a differential diagnosis when faced with unexpected findings in surgery.

Site-specific effects of mental practice combined with transcranial direct current stimulation on motor learning.

Mental practice can induce significant neural plasticity and result in motor performance improvement if associated with motor imagery tasks. Given the effects of transcranial direct current stimulation (tDCS) on neuroplasticity, the current study tested whether tDCS, using different electrode montages, can increase the neuroplastic effects of mental imagery on motor learning. Eighteen healthy right-handed adults underwent a randomised sham-controlled crossover experiment to receive mental training combined with either sham or active anodal tDCS of the right primary motor cortex (M1), right supplementary motor area, right premotor area, right cerebellum or left dorsolateral prefrontal cortex (DLPFC). Motor performance was assessed by a blinded rater using: non-dominant handwriting time and legibility, and mentally trained task at baseline (pre) and immediately after (post) mental practice combined with tDCS. Active tDCS significantly enhances the motor-imagery-induced improvement in motor function as compared with sham tDCS. There was a specific effect for the site of stimulation such that effects were only observed after M1 and DLPFC stimulation during mental practice. These findings provide new insights into motor imagery training and point out that two cortical targets (M1 and DLPFC) are significantly associated with the neuroplastic effects of mental imagery on motor learning. Further studies should explore a similar paradigm in patients with brain lesions.
