Microbiota has an important role in developing shrimp aquaculture and disease control. In the present study, pirA and pirB genes were amplified by PCR to confirm AHPND and non-AHPND in shrimp hepatopancreas; samples were sequenced using the MiSeq platform targeting the V3-V4 16S ribosomal (rRNA) hypervariable regions. Results demonstrated a diverse microbiota in the non-AHPND group, mainly composed of phyla Proteobacteria, Firmicutes, and Actinobacteria. Furthermore, Proteobacteria was the dominant phyla in the hepatopancreas infected with AHPND, while Firmicutes tended to decrease. Vibrio was the most abundant at the genus level, prevailing in some genera like Corynebacterium, Weissella, Lactobacillus, Photobacterium, and Geobacillus.

To characterize the geographic distribution of dengue and to evaluate the spatial autocorrelation with social and climatic determinants at the census-tract level in two medium sized cities in northwestern Mexico. Methods. In this work we apply spatial analysis ecological tools, such as the Moran’s Index and the Local Indicator of Spatial Association (LISA) method, to examine global and local spatial correlation between incidence of dengue, and socioeconomic and climatic factors at the census tract-level. For the analysis of the spatial clustering, the Getis-Ord method was used to find statistically significant hot spots in each city. Results. Overall, a global spatial autocorrelation could not be identified, although local clusters of a high dengue incidence, soil surface temperature ≤ 31 °C and high degree of social marginalization coincide. Discussion. We found that at the census-tract level in urban settings, socially disadvantaged populations showed higher clusters of dengue when compared to areas with better socioeconomic conditions. In the two study sites, a similar spatial pattern was observed when considering public health conditions and its aggregation with physical attributes using spatial analysis techniques, supporting the application of this technique for a better understanding about the dengue distribution in urban areas.","PeriodicalId":8876,"journal":{"name":"Biotecnia","volume":"208 4","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138981295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The regression model to explain the IP from the IS was significant and predictive for six species, being positive for Adelia virgata, Amaratus palmeri, Haematoxilon brasiletto, Lippia palmeri and Prosopis sp., and negative for Bursera microphyla.

Roselle calyxes were found to be a rich source of diverse polyphenols, including delphinidin sambubioside, caffeoylquinic acids, hibiscus acid, and citric acid as major components. Importantly, we extracted a significant proportion of these bioactive compounds during the decoction process, resulting in a polyphenol-rich beverage. The used calyces (decoction by-product) retained from 23 % to 140 % of the extractable polyphenols and organic acids found in roselle calyxes. Additionally, due to the leaching of hydrophobic components like soluble dietary fiber and extractable polyphenols and organic acids, the roselle by-product was enriched with non-extractable constituents attached to dietary fiber (126 % - 272 %).

Por lo anterior, en este trabajo se planteó analizar el efecto de las etapas del protocolo de crioconservación sobre la viabilidad y regeneración de embriones cigóticos de vid. La viabilidad del tejido (V) y la regeneración de plántulas (RP), mostraron que la PVS2 ejerce protección a los embriones (V:85%, RP:60%), mientras que la exposición combinada a la solución PVS2 y nitrógeno líquido (NL) ocasionó diminución de la viabilidad y regeneración (V:68%; RP: 2%). Un efecto más drástico se observó cuando el tejido fue expuesto a PVS2+NL y recalentamiento (RC) (V:68%; RP:0%).
