This study endeavored to test two hypotheses: (i) Hyalorbilia oviparasitica and related species (H. oviparasitica clade) will be detected in sugar beet fields in California’s Imperial Valley and (ii) the population densities of these fungi will increase in the presence of their nematode host (Heterodera schachtii) and a host plant of this nematode. The H. oviparasitica clade includes potent hyperparasites of sedentary stages of plant-parasitic nematodes, which have the ability to substantially suppress the population densities of several endoparasitic nematode species. In this study, 21 of 25 Imperial Valley soils cropped to sugar beets harbored members of the H. oviparasitica clade. The population densities of these fungi increased, on average, approximately 10,000-fold in the presence of H. schachtii and its host Swiss Chard over one nematode generation. An rRNA ITS sequence analysis showed that members of the H. oviparasitica clade were the dominant group of fungi associated with H. schachtii females derived from these soils. These results provide evidence supporting the hypotheses. [Formula: see text] Copyright © 2020 The Author(s).

We studied the effect of some mineral waters and some of their constituents on the apical uptake of 14C-butyrate (14C-BT) and 3H-O-methyl-D-glucose (3H-OMG) by Caco-2 cells. Uptake of 14C-BT increased after a 20-minute exposure to 1 % (v/v) distilled water, and, compared to distilled water, it was decreased by Pedras Salgadas® 1 % (v/v) and Melgaço® 5 % (v/v), and increased by Vidago® 5 % (v/v). Moreover, it increased after a 48-hour exposure to Vidago® or Melgaço® waters (5 % (v/v)). Also, uptake of 14C-BT was reduced after a 20-minute exposure to MgCl2, MgSO4, or CaCl2. Uptake of 3H-OMG was reduced after a 20-minute exposure to Melgaço® water [1 % (v/v)], when compared to distilled water. Also, a 48-hour exposure to Pedras Salgadas® or Melgaço® water (5 % (v/v)) increased and decreased uptake, respectively. Finally, uptake of 3H-OMG decreased after a 20-minute exposure to MgSO4 or NaF. In conclusion, uptake of 14C-BT and 3H-OMG by Caco-2 cells is differently modulated by distinct mineral waters.

On November 5, 2016, hundreds of people convened at the historical landmark of Chicano Park in Barrio Logan, San Diego, to celebrate the life of one of the community’s most revered elders, Ramón “Chunky” Moroyoqui Sánchez. Nuestro querido maestro falleció el día 28 de octubre de 2016. Sánchez, endearingly known as Chunky, was synonymous with Barrio Logan, Chicano Park, Chicano/a music, and San Diego in general. In this city, an auditorium is named in his honor. His image is incorporated in murals. The Chicano comedy troupe Culture Clash developed a vignette about Chunky, and upon his passing the San Diego Chargers’ website featured him in a blog post that included a photo of him with players and cheerleaders. Chunky was also well known beyond the Imperial Valley. The music of Los Alacranes Mojados (the group he started with his brother, Ricardo Sánchez) continues to be embraced in Mexicano/a and Chicano/a communities throughout California and the Southwest. The news of Sánchez’s passing reverberated throughout California like the violent ripples of a pond into which a boulder has been dropped. Ese vato will be missed.
