The enrollment of Black patients in cancer clinical trials continues to trend far below the true prevalence of disease in Black patients in the United States, limiting the generalizability of trial results. A potentially overlooked contributor to the underenrollment of Black patients may be the increasing enrollment of cancer trials in countries outside the United States. However, the impact of the globalization of cancer clinical trials on recruitment of racial minority patients has been understudied.
In this study, race and accrual location data for all cancer drugs approved by the US Food and Drug Administration (FDA) between 2015 and 2018 were analyzed. A disparity score was calculated for each approval, a metric comparing Black enrollment in clinical trials with the estimated burden of disease in Black patients.
Of 49 global clinical trials supporting 35 FDA drug approvals with race data available, Black patients accounted for 2.5% of enrollment (range, 0%-10%), with a median disparity score of 0.1f further exacerbating existing racial disparities in cancer clinical trial representation and ultimately the generalizability of trial results.
Cadmium uptake by cacao plants can affect plant growth, consumer health and commercialisation. To develop mitigation strategies, it is essential to identify the soil characteristics that could influence this absorption. To determine the relationships between cadmium absorption and the soil characteristics of cacao areas, the responses at concentrations of 0, 2, 5, 10 and 20 μg g
of cadmium in three soils of these areas and an andisol were evaluated, using 120-day-old seedlings of four cultivars of Theobroma cacao L.
In the present study, several relationships were found between chemical and physical soil characteristics and available cadmium, such as real and bulk densities, as well as contents of iron, sand, magnesium, potassium, sodium and copper. Additionally, moderate to strong correlations between potassium (r
= -0.56) and real density (r
= 0.42), with foliar cadmium, were found. Moreover, a differential deleterious effect on cacao growth in variables such as biomass was corroborated in cadmiumrrelation between potassium with foliar cadmium indicated that potassium could be significant in cadmium uptake mitigation strategies. The high correlation between available cadmium and foliar cadmium indicates that the quantification methodology developed using ethylenediaminetetraacetic acid extractant may be a useful diagnostic tool. © 2021 Society of Chemical Industry.The present study aimed to explore the impact of onion (Allium cepa Linnaeus) extract on testicular damage induced by dexamethasone. Forty male Wistar rats were divided into four groups (control, dexamethasone, onion extract and dexamethasone group treated with onion extract). Testosterone levels, antioxidant parameters and the expression of caspase-3 and IL-1β, IL-12, IL-10 genes, as well as histopathological examination and immunohistochemical studies of Bcl2 and caspase-9 expression, were examined. Dexamethasone was found to decrease GSH, total antioxidant activity and testosterone levels, meanwhile treatment with onion extract normalised these levels. MDA was increased in dexamethasone group but appeared normal in the treated group. Dexamethasone was shown to downregulate IL-10 and IL-2 gene expression. Conversely, IL-1β and caspase-3 gene expression were upregulated by dexamethasone and normalised in the treated group. Histopathological analysis found that dexamethasone caused atrophy to the seminiferous tubules and degeneration to spermatocytes, and immunohistochemical analysis showed overexpression of caspase-9 and inhibited the expression of Bcl-2 in dexamethasone group. These effects were normalised in the onion extract treated group. In conclusion, onion extract have a preventative effect against dexamethasone-induced testicular damage in rats; therefore, its use in complementary therapy is recommended.Nucleotide-binding domain and leucine-rich repeat receptor (NLR)-mediated inflammasome activation is important in host response to microbes, danger-associated molecular patterns (DAMPs) and metabolic disease. Some NLRs have been shown to interact with distinct cell metabolic pathways and cause negative regulation, tumorigenesis and autoimmune disorders, interacting with multiple innate immune receptors to modulate disease. NLR activation is therefore crucial in host response and in the regulation of metabolic pathways that can trigger a wide range of immunometabolic diseases or syndromes. However, the exact mode by which some of the less well-studied NLR inflammasomes are activated, interact with other metabolites and immune receptors, and the role they play in the progression of metabolic diseases is still not fully elucidated. In this study, we review up-to-date evidence regarding NLR function in metabolic pathways and the interplay with other immune receptors involved in GPCR signalling, gut microbiota and the complement system, in order to gain a better understanding of its link to disease processes.Kelp was first recorded for the remote warm-temperate Azores archipelago (central North Atlantic) in 1971, when a few Laminaria specimens were collected on the Formigas Bank at depths beyond conventional SCUBA diving reach. A shortage of technical means and projects targeting mesophotic environments has since kept this offshore marine protected area as the single known kelp occurrence site. Here, we present new kelp records collected on previously unexplored mesophotic reefs using remote imaging systems, open- and closed-circuit SCUBA diving, and fisheries bycatch information. The new data extend the known distribution range of kelp in the Azores 350 km to the west and 25 km to the southwest, henceforth including several island shelves in the eastern and central Azores. Selleck TKI-258 In addition to the previously recorded Laminaria ochroleuca, kelp specimens with a morphology akin to Phyllariopsis brevipes subsp. brevipes are also reported. For the first time, seabed imagery is used to document the depth-wise diversity of the Azores kelp beds and their associated biota.Selleck TKI-258
