“…These oscillating behaviors have been reported for a number of different NP in different media [36,52]. Sizes (as Feret diameters) of agglomerates measured by DLS were larger (10-50 times) than those evaluated by DIA as it was previously reported by other authors [53], who found similar differences when characterizing TiO 2 spheres NP, Al 2 O 3 NP, and SiO 2 NP suspended in FBS media. This difference was attributed by these authors to the electrical charged layer formed around the particles considered for the DIA experiments.…”

“…Interactions between components of media and the NP influenced the affinity and adhesion of such components on the NP thus promoting or preventing the formation of agglomerates with different morphologies, sizes, and . A number of works have been published in which the importance of evaluating the interactions of various media-NP such as fetal bovine serum-TiO 2 [53], TiO 2 -cell culture media [23], blood [67], and bronchioalveolar fluids [14] is stressed that form layers of proteins around NP named protein corona [54]. A number of studies have been carried out regarding TiO 2 effects in different in vivo and in vitro systems and it is noteworthy that different morphologies, sizes, and charge (as ) of the TiO 2 agglomerates and primary particles cause a number of biological changes when they are internalized into cells.…”

Titanium dioxide nanoparticles (TiO2NP) are possible carcinogenic materials (2B-IARC) and their toxicity depends on shape, size, and electrical charge of primary NP and on the system formed by NP media. The aim of this work was to characterize agglomerates of three TiO2NP by evaluating their morphometry, stability, and zeta potential (ζ) in liquid media and their changes with time. Sizes of agglomerates by dynamic light scattering (DLS) resulted to be 10–50 times larger than those obtained by digital image analysis (DIA) given the charged zone around particles. Fractal dimension (FD) was highest for agglomerates of spheres and belts in F12K, and in E171 in FBS media. E171 and belts increased FD with time. At time zero, using water as dispersant FD was larger for agglomerates of spheres than for of E171. Belts suspended in water had the smallest values of circularity (Ci) which was approximately unchanged with time. All dispersions hadζvalues around −30 mV at physiological pH (7.4) and dispersions of NP in water and FBS showed maximum stability (Turbiscan Lab analysis). Results help in understanding the complex NP geometry-size-stability relationships when performingin vivoandin vitroenvironmental-toxicity works and help in supporting decisions on the usage of TiO2NP.

“…Conversely, CaDIV14 was clustered with DIVARICATA -like genes that have been characterized for their participation in the flower development [ 39 ]. Since CaDIV14 did not show an expression in flower tissue, but it did exhibit the characteristic expression pattern for capsaicinoid biosynthetic genes, it is likely that this gene could be associated with the blister (capsaicin deposit) development process, which has been linked to the capsaicinoid accumulation [ 68 , 69 ].…”

The MYB transcription factor family is very large and functionally diverse in plants, however, only a few members of this family have been reported and characterized in chili pepper (Capsicum spp.). In the present study, we performed genome-wide analyses of the MYB family in Capsicum annuum, including phylogenetic relationships, conserved domain, gene structure organization, motif protein arrangement, chromosome distribution, chemical properties predictions, RNA-seq expression, and RT-qPCR expression assays. A total of 235 non-redundant MYB proteins were identified from C. annuum, including R2R3-MYB, 3R-MYB, atypical MYB, and MYB-related subclasses. The sequence analysis of CaMYBs compared with other plant MYB proteins revealed gene conservation, but also potential specialized genes. Tissue-specific expression profiles showed that CaMYB genes were differentially expressed, suggesting that they are functionally divergent. Furthermore, the integration of our data allowed us to propose strong CaMYBs candidates to be regulating phenylpropanoid, lignin, capsaicinoid, carotenoid, and vitamin C biosynthesis, providing new insights into the role of MYB transcription factors in secondary metabolism. This study adds valuable knowledge about the functions of CaMYB genes in various processes in the Capsicum genus.

“…At 44 dpa, stage of ripeness near to senescence, the ampullas collapsed. Ampulla formation and tissue morphological changes constitute an indicator of capsaicin production (Bhandari et al., 2016; Sánchez‐Segura et al., 2015). Bosland, Coon, and Cooke (2019) captured images using stereo‐fluorescence microscope from the pericarp of the superhot chili pepper cultivars.…”

“…Peppers have many nutraceutical benefits due to their content of phytochemicals, which is influenced by genotype, stage of maturity, and environmental, growing, and postharvest conditions (Bosland, 1996; Sánchez‐Segura et al., 2015). These fruits have considerable amounts of vitamins, phenolic compounds, and carotenoids, among other useful components.…”

Hot pepper (Capsicum annuum) fruits, usually termed as chili, have been used since ancient times as food vegetables, flavoring ingredients, natural colorants, and in traditional medicines. Nowadays, a wide variation of sweet and pungent peppers are consumed worldwide in a large variety of forms. Interestingly, the most important hot pepper at the global level in commercial terms is C. annuum with a high number of varieties. This review compares C. annuum to other Capsicum species for plant agronomic traits, biochemical composition, the content of capsaicin and capsaicinoids and their nutraceutical and medical potentialities, and the effects of processing on quality and key components of the fruit, among other aspects. Chili contains important levels of pigments (i.e., chlorophyll, anthocyanin, and lutein) with potential health benefits; it also contains additional outstanding health-promoting chemical compounds, such as vitamins, minerals, flavonoids, carotenoids, and capsaicinoids, in general. And capsaicin, the major active compound responsible for the pungent taste of these species has been proven to have a positive role in health. We report here on how dietary chili and capsaicinoids consumption, especially capsaicin, are involved in body weight reduction and their potential antiobesity effects, in urinary disorders, as well as antioxidants, antimicrobial, anticancer, and analgesic capacity. Selected characteristics of processing for the fruit preservation on its quality and content of these compounds are described as well. However, additional clinical research on the mechanism of action and efficacy of frequent capsaicinoid consumption on human health is needed.
