Nuevas Adaptaciones Para la Aplicación del Mindfulness a la Psicosis / New Adaptations in the Application of Mindfulness to Psychosis Spectrum Disorders

El uso clínico del mindfulness adaptado a la psicosis ha sido rechazado por algunos profesionales de la Salud Mental debido a prejuicios y falta de información. Sin embargo, la evidencia actual ha demostrado que las Intervenciones Basadas en Mindfulness (MBI) son seguras y tienen numerosos beneficios en los trastornos del espectro psicótico. Las MBI son adaptables a diferentes contextos y situaciones clínicas, incluido el deterioro cognitivo, y aunque no constituye su objetivo principal, pueden facilitar la reducción de la sintomatología negativa en la psicosis. Las MBI permiten a las personas con psicosis enfrentar las experiencias alucinatorias desde una perspectiva diferente, fomentando la flexibilidad, la regulación emocional y la aceptación. Es importante adaptar las intervenciones a las características de la psicosis, así como distinguir entre los diferentes tipos de prácticas, para aplicarlas de manera diferencial según la sintomatología específica y las características de la persona.(AU)

The clinical use of psychosis-adapted mindfulness has been rejected by some mental health professionals due to biases and lack of information. However, current evidence has demonstrated the safety and numerous benefits of mindfulness-based interventions (MBIs) in psychotic spectrum disorders. MBIs are adaptable to diverse clinical contexts and situations, including cognitive impairment, and although it is not their primary objective, they can facilitate the reduction of negative symptomatology in psychosis. MBIs enable individuals with psychosis toapproach hallucinatory experiences from an alternative perspective, fostering flexibility, emotional regulation, and acceptance. It is crucial to tailor interventions to the characteristics of the psychosis, as well as to differentiate between the various types of practices, in order to apply them differentially depending on the specific symptoms and characteristics of the individual.(AU)

Food Service Kitchen Scraps as a Source of Bioactive Phytochemicals: Disposal Survey, Optimized Extraction, Metabolomic Screening and Chemometric Evaluation.

Untargeted metabolomics is a powerful tool with high resolution and the capability to characterize a wide range of bioactive natural products from fruit and vegetable by-products (FVB). Thus, this approach was applied in the study to evaluate the phenolic compounds (PC) by metabolomic screening in five FVB after optimizing their extraction. The total phenolic content and antioxidant activity analyses were able to select the best extractor (SM) and ultrasonication time (US) for each FVB; methanol was used as a control. Although ultrasonication yielded a lower number of PC identifications (84 PC), the US extract was the most efficient in total ionic abundance (+21% and +29% compared to the total PC and SM extracts, respectively). Ultrasonication also increased the phenolic acid (+38%) and flavonoid classes (+19%) extracted compared to SM, while the multivariate analyses showed the control as the most dissimilar sample. FVB extracted from the same parts of the vegetable/fruit showed similarities and papaya seed presented the most atypical profile. The application of the metabolomics approach increased the knowledge of the bioactive potential of the evaluated residues and possibilities of exploring and valorizing the generated extracts.

Efficacy of the adjuvanted subunit protein COVID-19 vaccine, SCB-2019: a phase 2 and 3 multicentre, double-blind, randomised, placebo-controlled trial.

BACKGROUND: A range of safe and effective vaccines against SARS CoV 2 are needed to address the COVID 19 pandemic. We aimed to assess the safety and efficacy of the COVID-19 vaccine SCB-2019. METHODS: This ongoing phase 2 and 3 double-blind, placebo-controlled trial was done in adults aged 18 years and older who were in good health or with a stable chronic health condition, at 31 sites in five countries (Belgium, Brazil, Colombia, Philippines, and South Africa). The participants were randomly assigned 1:1 using a centralised internet randomisation system to receive two 0·5 mL intramuscular doses of SCB-2019 (30 µg, adjuvanted with 1·50 mg CpG-1018 and 0·75 mg alum) or placebo (0·9% sodium chloride for injection supplied in 10 mL ampoules) 21 days apart. All study staff and participants were masked, but vaccine administrators were not. Primary endpoints were vaccine efficacy, measured by RT-PCR-confirmed COVID-19 of any severity with onset from 14 days after the second dose in baseline SARS-CoV-2 seronegative participants (the per-protocol population), and the safety and solicited local and systemic adverse events in the phase 2 subset. This study is registered on EudraCT (2020-004272-17) and ClinicalTrials.gov (NCT04672395). FINDINGS: 30 174 participants were enrolled from March 24, 2021, until the cutoff date of Aug 10, 2021, of whom 30 128 received their first assigned vaccine (n=15 064) or a placebo injection (n=15 064). The per-protocol population consisted of 12 355 baseline SARS-CoV-2-naive participants (6251 vaccinees and 6104 placebo recipients). Most exclusions (13 389 [44·4%]) were because of seropositivity at baseline. There were 207 confirmed per-protocol cases of COVID-19 at 14 days after the second dose, 52 vaccinees versus 155 placebo recipients, and an overall vaccine efficacy against any severity COVID-19 of 67·2% (95·72% CI 54·3-76·8), 83·7% (97·86% CI 55·9-95·4) against moderate-to-severe COVID-19, and 100% (97·86% CI 25·3-100·0) against severe COVID-19. All COVID-19 cases were due to virus variants; vaccine efficacy against any severity COVID-19 due to the three predominant variants was 78·7% (95% CI 57·3-90·4) for delta, 91·8% (44·9-99·8) for gamma, and 58·6% (13·3-81·5) for mu. No safety issues emerged in the follow-up period for the efficacy analysis (median of 82 days [IQR 63-103]). The vaccine elicited higher rates of mainly mild-to-moderate injection site pain than the placebo after the first (35·7% [287 of 803] vs 10·3% [81 of 786]) and second (26·9% [189 of 702] vs 7·4% [52 of 699]) doses, but the rates of other solicited local and systemic adverse events were similar between the groups. INTERPRETATION: Two doses of SCB-2019 vaccine plus CpG and alum provides notable protection against the entire severity spectrum of COVID-19 caused by circulating SAR-CoV-2 viruses, including the predominating delta variant.

Structural, enzymatic and pharmacological profiles of AplTX-II - A basic sPLA2 (D49) isolated from the Agkistrodon piscivorus leucostoma snake venom.

A basic sPLA2 (D49) from the venom of snake Agkistrodon piscivorus leucostoma (AplTX-II) was isolated, purified and characterized. We determined the enzymatic and pharmacological profiles of this toxin. AplTX-II was isolated with a high level of purity through reverse phase chromatography and molecular exclusion. The enzyme showed pI 9.48 and molecular weight of 14,003 Da. The enzymatic activity of the AplTX-II depended on Ca2+ pH and temperature. The comparison of the primary structure with other sPLA2s revealed that AplTX-II presented all the structural reasons expected for a basic sPLA2s. Additionally, we have resolved its structure with the docked synthetic substrate NOBA (4-nitro-3-octanoyloxy benzoic acid) by homology modeling, and performed MD simulations with explicit solvent. Structural similarities were found between the enzyme's modeled structure and other snake sPLA2 X-Ray structures, available in the PDB database. NOBA and active-site water molecules spontaneously adopted stable positions and established interactions in full agreement with the reaction mechanism, proposed for the physiological substrate, suggesting that NOBA hydrolysis is an excellent model to study phospholipid hydrolysis.

Transposon based activation tagging in diploid strawberry and monoploid derivatives of potato.

KEY MESSAGE: Diploid strawberry and potato transformed with a transposon tagging construct exhibited either global (strawberry) or local transposition (potato). An activation tagged, compact-sized strawberry mutant overexpressed the gene adjacent to Ds. As major fruit and vegetable crops, respectively, strawberry and potato are among the first horticultural crops with draft genome sequences. To study gene function, we examined transposon-tagged mutant strategies in model populations for both species, Fragaria vesca and Solanum tuberosum Group Phureja, using the same Activation/Dissociation (Ac/Ds) construct. Early somatic transposition during tissue culture occurred at a frequency of 18.5% in strawberry but not in potato transformants. Green fluorescent protein under a monocot promoter was a more reliable selectable marker in strawberry compared to potato. BASTA (gluphosinate herbicide) resistance served as an effective selectable marker for both species (80 and 85% reliable in strawberry and potato, respectively), although the effective concentration differed (0.5% for strawberry and 0.03% for potato). Transposons preferentially reinserted within genes (exons and introns) in both species. Real-time quantitative PCR revealed enhanced gene expression (670 and 298-fold expression compared to wild type in petiole and leaf tissue, respectively) for an activation tagged strawberry mutant with Ds inserted about 0.6 kb upstream from a gene coding for an epidermis-specific secreted glycoprotein EP1. Our data also suggested that endopolyploid (diploid) cells occurring in leaf explants of monoploid potato were the favored targets of T-DNA integration during transformation. Mutants obtained in these studies provide a useful resource for future genetic studies.
