Assessment from the candica group associated with powdered cocoa bean fermentation through 2 areas throughout Colombia.
Flexible fiber supercapacitors are promising candidate for power supply of wearable electronics. Fabrication of high-performance fibers is in progress yet challenging. The currently available graphene fibers made from wet-spinning or electro-deposition technologies are far away from practical applications due to their unsatisfactory capacitance. Here we report a facile alternately dipping (AD) method to coat graphene on wire-like substrates. The excellent mechanical properties of the substrate with greatly diverse choices can be carried over to the fiber supercapacitors. Under such guideline, the graphene fiber with a titanium core made by our AD method (ADTi@RGO) shows an ultra-high specific capacitance of up to 1,722.1 mF cm-2, which is ∼1,000 times that of wet-spinning- and electro-deposition-fabricated neat graphene fibers and presents the highest specific capacitance to date. With excellent mechanical properties and striking electrochemical performances, the ADTi@RGO-based supercapacitors light the path to the next-generation technologies for wearable devices.From ontogenesis to homeostasis, the phenotypes of complex organisms are shaped by the bidirectional interactions between the host organisms and their associated microbiota. Current technology can reveal many such interactions by combining multi-omic data from both hosts and microbes. However, exploring the full extent of these interactions requires careful consideration of study design for the efficient generation and optimal integration of data derived from (meta)genomics, (meta)transcriptomics, (meta)proteomics, and (meta)metabolomics. In this perspective, we introduce the holo-omic approach that incorporates multi-omic data from both host and microbiota domains to untangle the interplay between the two. We revisit the recent literature on biomolecular host-microbe interactions and discuss the implementation and current limitations of the holo-omic approach. We anticipate that the application of this approach can contribute to opening new research avenues and discoveries in biomedicine, biotechnology, agricultural and aquacultural sciences, nature conservation, as well as basic ecological and evolutionary research.The American lobster (Homarus americanus) is one of the most iconic and economically valuable fishery species in the Northwestern Atlantic. Surface ocean temperatures are rapidly increasing across much of the species' range, raising concern about resiliency in the face of environmental change. Warmer temperatures accelerate rates of larval development and enhance survival to the postlarval stage, but the potential costs at the molecular level have rarely been addressed. We explored how exposure to current summer temperatures (16 °C) or temperature regimes mimicking projected moderate or extreme warming scenarios (18 °C and 22 °C, respectively) for the Gulf of Maine during development influences the postlarval lobster transcriptome. After de novo assembling the transcriptome, we identified 2542 differentially expressed (DE; adjusted p less then 0.05) transcripts in postlarvae exposed to 16 °C vs. 22 °C, and 422 DE transcripts in postlarvae reared at 16 °C vs. 18 °C. Lobsters reared at 16 °C significantly over-expressed transcripts related to cuticle formation and the immune response up to 14.4- and 8.5-fold respectively, relative to those reared at both 18 °C and 22 °C. In contrast, the expression of transcripts affiliated with metabolism increased up to 7.1-fold as treatment temperature increased. These results suggest that lobsters exposed to projected warming scenarios during development experience a shift in the transcriptome that reflects a potential trade-off between maintaining immune defenses and sustaining increased physiological rates under a warming environment. #link# This could have major implications for post-settlement survival through increased risk of mortality due to disease and/or starvation if energetic demands cannot be met.Heteroplasmy in patients affected with Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-like episodes (MELAS) offers a chance to harvest specific cells which might have a very low or no mutation load of the mitochondrial DNA. Here we demonstrate establishment of induced pluripotent stem cells (iPSC) cell lines (with normal mitochondrial DNA copies), from unaffected tissues of a male patient with MELAS harbouring m.3243A > G mutations. This platform allowed us to compare specific pathway differences between the cells of the affected tissues of the patients and their isogenic counterparts derived from iPSCs, which do not harbour the mutations.Duchenne muscular dystrophy (DMD) is a severe and rapidly progressive hereditary muscular disease with X-linked recessive inheritance, occurring mainly in males. A complete loss of dystrophin resulted from out-of-frame deletion mutations in the DMD gene leads to Duchenne muscular dystrophy. G418 induced pluripotent stem cells (iPSCs) are a suitable cell model to study muscle development and disease mechanisms underlying muscular dystrophy and to screen novel compounds with potential therapeutic effects. We generated iPSCs from a DMD patient using non-integrating episomal plasmid vectors. The obtained iPSC lines showed ESC-like morphology, expression pluripotency markers, displayed a normal karyotype and possessed trilineage differentiation potential.OCT4 and NANOG are core transcription factor genes in self-renewal, differentiation, and reprogramming. Here, we generated an OCT4-EGFP, NANOG-tdTomato dual reporter hiPSC line, KKUi001-A, on the basis of human induced pluripotent stem cells using CRISPR/Cas9 technology. EGFP and tdTomato reporter were inserted into before the stop codon of OCT4 and NANOG, respectively. Simultaneous expression of EGFP and tdTomato was observed when expression of OCT4 and NANOG was changed during differentiation and reprogramming. KKUi001-A hiPSC line will be a useful tool to find initial time point of OCT4 and NANOG expression during reprogramming process and to screen small molecules that promote reprogramming.Leigh syndrome is a rare multi-organ system disorder that affects less than 1 in 5000 births. In cases where clinical heterogeneity makes some presentations difficult to categorize as Leigh syndrome, but are highly suggestive, those are referred to as Leigh-like syndrome. It may present with delay after birth and can be slightly milder than classic Leigh. We have created an iPSC line for the novel variants in the ECHS1 gene that was reported in our patient. This cellular model is being used to determine prospective treatment opportunities for the patient.
