Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional harvest of Achyrocline satureioides (AS) occurs at dawn on Good Friday in some South American countries. Inflorescences are traditionally used as infusions for several disorders, including neuropsychiatric disorders. Pillows and cushions are popularly filled with AS to attenuate the symptoms of depression, anxiety, and sleep disturbances. However, evidence for the potential beneficial effects of AS on human neural cells remains unclear. AIM OF THE STUDY An in vitro model of SH-SY5Y human neural cells was applied to evaluate the effect of AS infusion, prepared as commonly used, on cells exposed to rotenone and to investigate its potential for neuropsychiatric disorders. MATERIALS AND METHODS A hot aqueous extract was obtained from a traditionally prepared AS inflorescence infusion and chemically characterized by high-resolution mass spectrometry and spectrophotometric quantification of total polyphenols, tannins, and flavonoids. The SH-SY5Y cell cultures were treated with AS extract at concentrations of 1, 3, 5, 10, 50, 100, and 300 μL/mL to determine the potential cyto- and genotoxic effects of AS on neural cells using MTT, Neutral Red, and GEMO assays. Apoptosis modulation was assessed using flow cytometry and apoptosis-modulating genes were evaluated by qRT-PCR. The protective effect of AS on the neurotoxicity triggered by rotenone exposure (30 nM) was determined by analyzing cellular viability and oxidative markers such as lipid peroxidation and protein carbonylation, and DNA damage was assessed by micronucleus assay. RESULTS The AS extract, as traditionally prepared, had estimated concentrations of 409.973 ± 31.107 μg/mL, 0.1041 ± 0.0246 mg GAE/mL, and 63.309 ± 3.178 mg QE/mL of total tannins, total polyphenols, and flavonoids, respectively. At concentrations of 30 and 100 μl/mL, AS decreased apoptotic events, whereas the highest concentration (300 μl/mL) increased apoptosis compared to that in the control (p < 0.05). In cells exposed to rotenone, AS treatment induced cell proliferation, reduced DNA damage (as evaluated by micronuclei), and reduced lipid and protein oxidation. CONCLUSIONS The data indicate the non-cytotoxic and beneficial effects of AS extract on human neural cells by reducing cellular mortality and oxidative stress in neural cells triggered by rotenone exposure.

Abstract
Since antiquity, humans have known about plants as a medicinal cure. Recently, plant extracts are attracting more attention as a result of their natural origin and wide range of desirable features. Nanotechnology's progress and innovations enable the production of novel materials with enhanced properties for a broad range of applications. Electrospinning is a cutting-edge, flexible and economical technique that allows the creation of continuous nano- and microfibrous membranes with tunable structure, characteristics and functionalities. Electrospun fibrous materials are used in drug delivery, tissue engineering, wound healing, cosmetics, food packaging, agriculture and other fields due to their useful properties such as a large surface area to volume ratio and high porosity with small pore size. By encapsulating plant extracts in a suitable polymer matrix, electrospinning can increase the medicinal potential of these extracts, thus improving their bioavailability and maintaining the required concentration of bioactive compounds at the target site. Moreover, the created hybrid fibrous materials could possess antimicrobial, antifungal, antitumor, anti-inflammatory and antioxidant properties that make the obtained structures attractive for biomedical and pharmaceutical applications. This review summarizes the known approaches that have been applied to fabricate fibrous materials loaded with diverse plant extracts by electrospinning. Some potential applications of the extract-containing micro- and nanofibers such as wound dressings, drug delivery systems, scaffolds for tissue engineering and active food packaging systems are discussed.

Maternal ingestion of cocoa causes constriction of fetal ductus arteriosus in rats. Sci Rep 2021; 11:9929.

Abstract
Maternal consumption of polyphenol-rich foods has been associated with fetal ductus arteriosus constriction (DAC), but safety of chocolate exposure in fetal life has not been studied. This experimental study tested the hypothesis that maternal cocoa consumption in late pregnancy causes fetal DAC, with possible associated antioxidant effects. Pregnant Wistar rats, at the 21st gestational day, received by orogastric tube cocoa (720 mg/Kg) for 12 h, indomethacin (10 mg/Kg), for 8 h, or only water, before cesaren section. Immediately after withdrawal, every thorax was obtained and tissues were fixed and stained for histological analysis. The ratio of the narrowest part of the pulmonary artery to the fetal ductus inner diameter and increased ductal inner wall thickness characterized ductal constriction. Substances reactive to thiobarbituric acid were quantified. Statistical analysis used ANOVA and Tukey test. Cocoa (n = 33) and indomethacin (n = 7) reduced fetal internal ductus diameter when compared to control (water, n = 25) (p < 0.001) and cocoa alone increased ductus wall thickness (p < 0.001), but no change was noted in enzymes activity. This pharmacological study shows supporting evidences that there is a cause and effect relationship between maternal consumption of cocoa and fetal ductus arteriosus constriction. Habitual widespread use of chocolate during gestation could account for undetected ductus constriction and its potentially severe consequences, such as perinatal pulmonary hypertension, cardiac failure and even death. For this reason, dietary guidance in late pregnancy to avoid high chocolate intake, to prevent fetal ductal constriction, may represent the main translational aspect of this study.
