In summary, this study investigated the effect of chitosan (CS) in the morphological, chemical, and physical aspects of PLA-based membranes incorporating chitosan obtained by electrospinning process, their adsorption behavior in multielement aqueous systems containing Cr, Cu, Zn, Mn , Ni, and Cd in pH 4, and the possible removal mechanism on the composite electrospun membrane's surface.

Fungi associated with orange juice production and assessment of adhesion ability and resistance to sanitizers.

Orange juice is widely consumed worldwide due to its sensory and nutritional characteristics. This beverage is susceptible to contamination by acidic-tolerant microorganisms due to its low pH, especially filamentous fungi and yeasts. To minimize fungal spoilage, companies usually submit juice to thermal treatments; sanitizers are also applied on surfaces to maintain the microbiological quality.

Venom proteomics and Duvernoy's venom gland histology of Pseudoboa neuwiedii (Neuwied's false boa; Dipsadidae, Pseudoboini).

The venom of Colombian specimens of the rear-fanged snake Pseudoboa neuwiedii contains proteolytic and phospholipase A (PLA) activities, but is devoid of esterases. Mass spectrometric analysis of electrophoretic bands indicated that this venom contains C-type lectins (CTL), cysteine-rich secretory proteins (CRiSP), PLA, snake venom metalloproteinases (SVMP), and snake venom matrix metalloproteinases (svMMP). In this investigation, we extended our characterization of P.

Plasma miRNAs Correlate with Structural Brain and Cardiac Damage in Friedreich's Ataxia.

Friedreich's Ataxia (FRDA) is the most common autosomal recessive ataxia worldwide and is caused by biallelic unstable intronic GAA expansions at FXN. With its limited therapy and the recent approval of the first disease-modifying agent for FRDA, the search for biological markers is urgently needed to assist and ease the development of therapies. MiRNAs have emerged as promising biomarkers in various medical fields such as oncology, cardiology, epilepsy and neurology as well.

Parasite-Driven host manipulation: The case of trematodes in Neotropical tadpoles.

Parasites can impact tadpole survival in both lethal and sublethal ways. Sublethal effects include alterations in morphology and behavior, reduced competitive ability, and increased vulnerability to predation, while lethal effects result in direct mortality. These impacts can have significant consequences at both individual and population levels, especially given that amphibians host various parasites and pathogens, which may contribute to population declines.

Leak detection and localization in water distribution systems via multilayer networks.

The continuous increase of water distribution networks (WDNs) in size and complexity poses significant management challenges, including a high risk of failures. Due to the intrinsic interconnected feature of water flow, including losses, this study proposes a methodology based on graph correlation and multilayer network analysis for leak detection and localization in WDNs with multiple components (infrastructure, control devices, hydraulic sensors). The detection process involves correlating monitored data to create a temporal graph and classify vertices.

Infliximab monitoring in Crohn's disease: a neural network approach for evaluating disease activity and immunogenicity.

Background: The treatment for Crohn's disease (CD) has increasingly required the use of biological agents. Safe and affordable tests have led to the active implementation of therapeutic drug monitoring (TDM) in clinical practice, which, although not yet widely available across all health services, has been proven effective.

Objective: To analyze serum infliximab (IFX) and antidrug antibody (ADA) levels in CD patients, compare two tests, as well as construct a prediction of neural network using a combination of clinical, epidemiological, and laboratory variables.

Effect of high hydrostatic pressure on the physicochemical characteristics of low sodium mortadella containing a high level of mechanically deboned poultry chicken meat.

The aim of this study was to evaluate the effect of HHP (100 and 200 MPa) on low-sodium mortadella produced with high content of mechanically deboned poultry meat (MDPM). Seven treatments were produced: FC (2.

Patterns of cognitive decline across different multiple sclerosis clinical courses.

Background: It is still unclear whether patients with progressive MS (PMS) present a distinct pattern of cognitive impairment (CI) and different trajectories of cognitive and clinical decline compared to patients with relapsing-remitting MS (RRMS) with similar age. In addition, the role of reserve (cognitive and cerebral) in cognitive decline in the different forms of MS is not fully understood, and some studies suggest that its effects reduce in the progressive forms.

Objective: To assess the trajectories of cognitive decline in RRMS and PMS patients with similar age, also evaluating the predictive power of baseline clinical and MRI features on cognitive outcomes at follow-up.

The resolvin D2 and omega-3 polyunsaturated fatty acid as a new possible therapeutic approach for inflammatory bowel diseases.

Inflammatory bowel diseases (IBD) are idiopathic disorders characterized by chronic gastrointestinal inflammation. Given conventional therapies' adverse effects and clinical failures, novel approaches are being investigated. Recent studies have highlighted the role of specialized pro-resolving lipid mediators (SPMs) in the active resolution of chronic inflammation.

The complete genome sequence of " Liberibacter asiaticus" strain 9PA and the characterization of field strains in the Brazilian citriculture.

Unlabelled: " Liberibacter asiaticus" (CLas) is associated with citrus huanglongbing, a severe disease with global importance that affects citrus production in Brazil. This study reports the first complete genome of a Brazilian strain of CLas. The genomic structure comparison of strain 9PA with those of 13 complete CLas genomes revealed 9,091 mismatches and 992 gaps/insertions, highlighting eight locally colinear blocks, among which six are in the prophage region.

NOD2 protects against allergic lung inflammation in obese female mice.

Obesity is associated with compartmentalized changes in immune responses that can be protective or pathogenic. It has been proposed that obesity-related changes in the microbiota influence allergic lung inflammation. We hypothesized that sensors of the bacterial cell wall influenced allergenic lung inflammation during obesity.

Selective blockade of cannabinoid receptors influences motoneuron survival and glial responses after neonatal axotomy.

Sciatic nerve crush in neonatal rats leads to an extensive death of motor and sensory neurons, serving as a platform to develop new neuroprotective approaches. The endocannabinoid system plays important neuromodulatory roles and has been involved in neurodevelopment and neuroprotection. The present work investigated the role of the cannabinoid receptors CB1 and CB2 in the neuroprotective response after neonatal axotomy.

Disruption of exploratory behavior and olfactory memory in cockroaches exposed to sublethal doses of the neonicotinoid Thiamethoxam.

Neonicotinoid insecticides (NNI) are agonists of insect nicotinic acetylcholine receptors (nAChR) that induce non-elucidate mechanisms of abnormal behavior in insects. In this work, we investigated the effects of sublethal doses of the neonicotinoid thiamethoxam (TMX) on neurochemical and physiological parameters in cockroaches. Sublethal doses of TMX (0.

NEK10 kinase ablation affects mitochondrial morphology, function and protein phosphorylation status.

Background: NEK10, a serine/threonine/tyrosine kinase belonging to the NEK (NIMA-related kinases) family, has been associated with diverse cellular processes. However, no specific target pathways have been identified. Our previous work knocking down NEK10 in HeLa cells suggested a functional association with mitochondria, as we observed altered mitochondrial morphology, mitochondrial oxygen consumption, mtDNA integrity, and reactive oxygen species levels.

Management of C2 fractures following multiple classifications, a narrative review.

Introduction: Classifications are helpful for surgeons as they can be a resource for decision-making, often providing the individual indicators that may deem a case necessary for surgery. However, when there are multiple classifications, the decision-making might be compromised. That is the case with C2 fractures.
