External morphology and growth patterns of larvae and juveniles of Bryconops gracilis (Characiformes, Iguanodectidae) from Amazon basin.

During early development, fishes undergo significant changes that influence external morphology and the functioning of internal organs and systems. This often results in gradual variation of the morphological traits of individuals across developmental stages. The investigation of larval and juvenile fish development and growth patterns has pertinent implications for the systematic and ecological elucidation of species.

"I Got Laughed at for the Shuffle Noise I Make": Parkinson's Disease and Stigma.

People with Parkinson's disease (PD) are at risk for stigma. The stigma theory suggests four stigma types: public stigma, self-stigma, stigma by association, and structural stigma. The purposes of this study were to understand how people with PD and caregivers perceived and experienced stigma, review the literature and scan social media for evidence of stigma and PD, and examine the interrelationships between stigma types.

Dynamic Covalent Optical Chirality Sensing with a Sterically Encumbered Aminoborane.

A sterically encumbered aminoborane sensor is introduced and used for quantitative stereochemical analysis of monoalcohols, diols and amino alcohols. The small-molecule probe exhibits a rigid ortho-substituted arene scaffold with a proximate boron binding site and a triarylamine circular dichroism (CD) reporter unit which proved to be crucial for the observed chiroptical signal induction. Coordination of the chiral target molecule produces strong Cotton effects and UV changes that are readily correlated to its absolute configuration, enantiomeric composition and concentration to achieve comprehensive stereochemical analysis within a 5 % absolute error margin.

Optical Detection of Stereoselective Interactions with DNA-Wrapped Single-Wall Carbon Nanotubes.

DNA-wrapped carbon nanotubes have been explored increasingly as sensitive near-infrared fluorescence probes for biomolecules. However, notably missing in previous studies is an inquiry on stereoselective interactions between DNA-wrapped carbon nanotubes and biomolecules. Here, enantiopure (+) and (-)(6,5), and (-)(8,3) as well as achiral (11,0) carbon nanotubes wrapped with specific resolving DNA sequences are used to demonstrate their stereoselective detection of amino acid enantiomers.

Microglial Metamorphosis in Three Dimensions in Virus Limbic Encephalitis: An Unbiased Pictorial Representation Based on a Stereological Sampling Approach of Surveillant and Reactive Microglia.

Microglia influence pathological progression in neurological diseases, reacting to insults by expressing multiple morphofunctional phenotypes. However, the complete morphological spectrum of reactive microglia, as revealed by three-dimensional microscopic reconstruction, has not been detailed in virus limbic encephalitis. Here, using an anatomical series of brain sections, we expanded on an earlier Piry arbovirus encephalitis study to include CA1/CA2 and assessed the morphological response of homeostatic and reactive microglia at eight days post-infection.

Microglial Morphology Across Distantly Related Species: Phylogenetic, Environmental and Age Influences on Microglia Reactivity and Surveillance States.

Microglial immunosurveillance of the brain parenchyma to detect local perturbations in homeostasis, in all species, results in the adoption of a spectrum of morphological changes that reflect functional adaptations. Here, we review the contribution of these changes in microglia morphology in distantly related species, in homeostatic and non-homeostatic conditions, with three principal goals (1): to review the phylogenetic influences on the morphological diversity of microglia during homeostasis (2); to explore the impact of homeostatic perturbations (Dengue virus challenge) in distantly related species ( and ) as a proxy for the differential immune response in small and large brains; and (3) to examine the influences of environmental enrichment and aging on the plasticity of the microglial morphological response following an immunological challenge (neurotropic arbovirus infection). Our findings reveal that the differences in microglia morphology across distantly related species under homeostatic condition cannot be attributed to the phylogenetic origin of the species.

Optical Terpene and Terpenoid Sensing: Chiral Recognition, Determination of Enantiomeric Composition and Total Concentration Analysis with Late Transition Metal Complexes.

Quantitative chirality sensing of terpenes and terpenoids exhibiting a single double bond as the only functional group, such as α-pinene, β-pinene and camphene, or two alkene moieties like limonene, valencene, and β-caryophyllene is among the most difficult molecular recognition tasks. In this work, a fast chiroptical sensing method that accomplishes determination of the enantiomeric excess and overall amount of a large variety of terpenes and terpenoids using readily available phosphine derived late transition metal complexes is presented. The terpene coordination is complete within 10 min and coincides with spontaneous induction of strong CD signals at long wavelengths and distinct UV changes which together allow accurate and concentration quantification.

Effectiveness of Two Dietary Approaches on the Quality of Life and Gastrointestinal Symptoms of Individuals with Irritable Bowel Syndrome.

To evaluate the effectiveness of a low FODMAP (fermentable oligosaccharides, monosaccharaides, disaccharides and polyols) diet in the relief of symptoms and an improvement of the quality of life in individuals with irritable bowel syndrome in comparison to a standard diet according to the British Dietetic Association's guidelines. A non-randomized clinical trial of adult patients with IBS was compared two diet interventions. An assessment of symptoms, quality of life, and nutritional status was performed before and after the four-week mark of intervention.

Tandem Use of Optical Sensing and Machine Learning for the Determination of Absolute Configuration, Enantiomeric and Diastereomeric Ratios, and Concentration of Chiral Samples.

We have developed an optical method for accurate concentration, er, and dr analysis of amino alcohols based on a simple mix-and-measure workflow that is fully adaptable to multiwell plate technology and microscale analysis. The conversion of the four aminoindanol stereoisomers with salicylaldehyde to the corresponding Schiff base allows analysis of the dr based on a change in the UV maximum at 420 nm that is very different for the homo- and heterochiral diastereomers and of the concentration of the sample using a hypsochromic shift of another absorption band around 340 nm that is independent of the analyte stereochemistry. Subsequent in situ formation of Cu assemblies in the absence and presence of base enables quantification of the er values for each diastereomeric pair by CD analysis.

Upregulation of p53 through induction of MDM2 degradation: Anthraquinone analogs.

In a previous study, a novel anthraquinone analog BW-AQ-101 was identified as a potent inducer of MDM2 degradation, leading to upregulation of p53 and apoptosis in cell culture studies. In animal models of acute lymphocytic leukemia, treatment with BW-AQ-101 led to complete disease remission. In this study, we systematically investigated the effect of substitution patterns of the core anthraquinone scaffold.

Intervention with a combined physical exercise training to reduce oxidative stress of women over 40 years of age.

Exercise training has been shown to be one of the most important lifestyle factor for improving functional performance and health status. Nevertheless, and although some evidence exists about the effects of aerobic training on oxidative stress, there is scarce information concerning the effects of combined exercise training (aerobic and strength training) in oxidative stress. Considering this, the aim of this study was to verify the effects of a combined exercise training in oxidative stress parameters of women over 40 years of age.
