[Ab] Resumo:Porcine epidemic diarrhea virus (PEDV) causes severe diarrhea and high fatality of piglets, influencing the swine industry. Japanese horse chestnut (seed of Aesculus turbinata) contains many saponin mixtures, called escins, and has been used for a long time as a traditional medicinal plant. Structure-activity relationship (SAR) studies on escins have revealed that acylations at C-21 and C-22 with angeloyl or tigloyl groups were important for their cytotoxic effects. However, the strong cytotoxicity of escins makes them hard to utilize for other diseases and to develop as nutraceuticals. In this research, we investigated whether escin derivatives 1-7 (including new compounds 2, 3, 5 and 6), without the angeloyl or tigloyl groups and with modified glycosidic linkages by hydrolysis, have PEDV inhibitory effects with less cytotoxicity. Compounds 1-7 had no cytotoxicity at 20µM on VERO cells, while compounds 8-10 showed strong cytotoxicity at similar concentrations on PEDV. Our results suggest that escin derivatives showed strong inhibitory activities on PEDV replication with lowered cytotoxicity. These studies propose a method to utilize Japanese horse chestnut for treating PEDV and to increase the diversity of its bioactive compounds.

[Ab] Resumo:We attempted to evaluate the contents and distribution of antioxidants in the whole seeds, seed shells, and peeled seeds of the Japanese horse chestnut. The seed shells exhibited the highest antioxidant activities due to the presence of highly polymeric proanthocyanidins as we have reported recently. On the other hand, the peeled seeds predominantly contained flavonols such as quercetin and kaempferol at a high level of 66.7% of total polyphenols, also contributing to the predominant antioxidant activities. The instrumental analysis of the extract from the whole seeds revealed the identification of eight flavonol O-glycosides, including six compounds with quercetin and two species with kaempferol as aglycones. The isolated species exhibited different antioxidant activities depending on the types of aglycones, glycosides, and acylated moieties. The results indicate that the peeled seeds are a good source of flavonol O-glycosides serving as antioxidants to be used for food additives and dietary supplements.

[Ti] Título:Small genomes and large seeds: chromosome numbers, genome size and seed mass in diploid Aesculus species (Sapindaceae).

[Ab] Resumo:Background and Aims: Aesculus L. (horse chestnut, buckeye) is a genus of 12-19 extant woody species native to the temperate Northern Hemisphere. This genus is known for unusually large seeds among angiosperms. While chromosome counts are available for many Aesculus species, only one has had its genome size measured. The aim of this study is to provide more genome size data and analyse the relationship between genome size and seed mass in this genus. Methods: Chromosome numbers in root tip cuttings were confirmed for four species and reported for the first time for three additional species. Flow cytometric measurements of 2C nuclear DNA values were conducted on eight species, and mean seed mass values were estimated for the same taxa. Key Results: The same chromosome number, 2 n = 40, was determined in all investigated taxa. Original measurements of 2C values for seven Aesculus species (eight taxa), added to just one reliable datum for A. hippocastanum , confirmed the notion that the genome size in this genus with relatively large seeds is surprisingly low, ranging from 0·955 pg 2C -1 in A. parviflora to 1·275 pg 2C -1 in A. glabra var. glabra. Conclusions: The chromosome number of 2 n = 40 seems to be conclusively the universal 2 n number for non-hybrid species in this genus. Aesculus genome sizes are relatively small, not only within its own family, Sapindaceae, but also within woody angiosperms. The genome sizes seem to be distinct and non-overlapping among the four major Aesculus clades. These results provide an extra support for the most recent reconstruction of Aesculus phylogeny. The correlation between the 2C values and seed masses in examined Aesculus species is slightly negative and not significant. However, when the four major clades are treated separately, there is consistent positive association between larger genome size and larger seed mass within individual lineages.

[Ti] Título:Molecular Mechanism for Cellular Response to ß-Escin and Its Therapeutic Implications.

[Ab] Resumo:ß-escin is a mixture of triterpene saponins isolated from the horse chestnut seeds (Aesculus hippocastanum L.). The anti-edematous, anti-inflammatory and venotonic properties of ß-escin have been the most extensively clinically investigated effects of this plant-based drug and randomized controlled trials have proved the efficacy of ß-escin for the treatment of chronic venous insufficiency. However, despite the clinical recognition of the drug its pharmacological mechanism of action still remains largely elusive. To determine the cellular and molecular basis for the therapeutic effectiveness of ß-escin we performed discovery and targeted proteomic analyses and in vitro evaluation of cellular and molecular responses in human endothelial cells under inflammatory conditions. Our results demonstrate that in endothelial cells ß-escin potently induces cholesterol synthesis which is rapidly followed with marked fall in actin cytoskeleton integrity. The concomitant changes in cell functioning result in a significantly diminished responses to TNF-α stimulation. These include reduced migration, alleviated endothelial monolayer permeability, and inhibition of NFκB signal transduction leading to down-expression of TNF-α-induced effector proteins. Moreover, the study provides evidence for novel therapeutic potential of ß-escin beyond the current vascular indications.

[Ab] Resumo:Many insects are reported to damage cultivated chestnut (Castanea sativa Mill.; Fagaceae) in Italy, but the most important pests of chestnut fruits are weevils (Curculio elephas Gyll. and Curculio glandium Marsh.; Curculionidae) and tortricid moths (Pammene and Cydia; Tortricidae) (Pollini, 1998, Speranza, 1999). The larvae of the tortricid pests develop internally, tunnelling in the fruits and eating the endocarp (Rotundo et al. 1991), which significantly reduces nut quality and commercial value. The most damaging tortricid moths in the Italian chestnut industry are Pammene fasciana (Linnaeus) (the early chestnut moth), Cydia fagiglandana (Zeller) (the intermediate chestnut moth), and Cydia splendana (Hübner) (the late chestnut moth) (Pedrazzoli et al. 2012). Pammene castanicola Trematerra & Clausi, 2009 was recently described from chestnut woods near Etna Vulcan, Sicily (Trematerra and Clausi 2009), and it is known only from the vicinity of the type locality. It is similar to Pammene fasciana in morphological and biological features, and it was previously misidentified as P. fasciana. We provide observations on the biology and larval development and present detailed descriptions and illustrations of the mature larva of P. castanicola, with comments on the differences between P. castanicola and P. fasciana.

[Ab] Resumo:PURPOSE: To evaluate the medical and surgical management and treatment of ocular injuries with chestnut burr recorded at the Hospital El Bierzo between 2009 and 2015. METHODS: A prospective study of ocular injuries with chestnut burr was conducted for the period from 2009 to 2015. Patients were detected in the Emergency Department and referred to the Ophthalmology Department for study and medical and surgical treatment. Ten eyes were evaluated in 10 patients. The injuries ranged from ocular contusion without corneal involvement to trauma with corneal perforation caused by spines. One patient with chronic retention of spines in the intrastromal corneal ring was included. RESULTS: Six of the eyes studied had chestnut burr spines in the cornea, one of which was chronically retained in the intrastromal cornea. One case of spine-induced corneal perforation was also studied. Six of the patients required surgery, 2 required removal of the spine using a slit lamp, 2 required outpatient medical treatments, and a wait-and-see approach was taken in 1 patient. All patients progressed favorably, and no surgical complications were recorded. CONCLUSIONS: Proper occupational risk prevention and the use of eye protection glasses are fundamental in avoiding these accidents. Once they have occurred, medical and surgical management must be done early and on an individual basis depending on the severity and location of the injuries, to avoid potentially serious complications.

[Ab] Resumo:Cytokines, such as transforming growth factor (TGF)-ß1, and increased oxidative stress are considered to be responsible for the development of diabetic nephropathy. We hypothesized that Aesculus hippocastanum (AH) seeds may have preventive effects on oxidative stress and TGF-ß-related diabetic nephropathy in streptozotocin (STZ)-induced diabetic nephropathy in rats. Twenty-one male Sprague-Dawley albino rats were divided into three groups (n=7). Except for the control group, they all had diabetic nephropathy induced by an intraperitoneal injection of STZ. While the diabetes group did not receive any medication, the diabetes+AH group was given the medication for 4 weeks. After the experiment, analyses were performed to evaluate the glomerular area, severity of sclerosis, and fibronectin immunoexpression, as well as levels of malondialdehyde (MDA), TGF-ß, blood urea nitrogen (BUN), blood glucose, creatinine, and proteinuria. It was found that glomerular area, severity of sclerosis, fibronectin immunoexpression, and levels of MDA, TGF-ß, BUN, creatinine, and proteinuria were decreased in the diabetes+AH group. It is known that diabetic nephropathy is induced, to a large extent, by hyperglycemia. In the present study, AH extract ameliorated diabetic nephropathy without decrease in blood glucose levels. In the study, AH seeds showed beneficial effects on the functional properties of the kidney and microscopic improvements in diabetic nephropathy.

Repeated small bowel obstruction due to the ingestion of the same food is extremely rare. We present the case of 63-year-old woman who developed small bowel obstruction twice due to the ingestion of chestnuts without the formation of phytobezoars. This is the first reported case of repeated small bowel obstruction caused by chestnut ingestion. Careful interviews are necessary to determine the meal history of elderly patients and psychiatric patients.

[Ab] Resumo:Hippocastaneae is a well-supported clade in Sapindaceae that comprises 15+ species; 12+ in Aesculus, two in Billia, and one in Handeliodendron Rehder. The monophyly of Aesculus and Billia were widely assumed, but a recent molecular phylogenetic study of Sapindanceae used seven species of Aesculus and one each of Billia and Handeliodendron and showed that Billia and Handeliodendron were nested within Aesculus. Here, we tested the hypothesis that Aesculus and Billia are mutually monophyletic using phylogenetic analyses of seven molecular markers and 31 accessions of Hippocastaneae representing 14 species. We performed phylogenetic analyses using a dataset of concatenated genes as well as with coalescent method for constructing a species tree from individual gene trees. The analysis of seven concatenated markers and the species tree strongly supported the mutual monophyly of Aesculus and Billia. We also recovered support for the traditional arrangement of genera within Hippocastaneae: Aesculus and Billia comprising a clade that is sister to Handeliodendron. However, the relationships among the genera remain incompletely resolved.

[Ab] Resumo:Recalcitrant seeds are typical of some tropical and subtropical trees. Their post-shedding life activity proceeds in humid air and wet litter. They are desiccation sensitive and, for this reason, have a short life span and need some special procedures for cryopreservation. This review is devoted to the post-shedding life strategy of recalcitrant seeds, which includes the maintenance of high hydration status, metabolic readiness and ability to rapidly germinate before desiccation-induced damage exerts a lethal effect. The main physiological aspects of recalcitrant seeds are considered starting from mature seeds, followed during dormancy if occurs and resulting in germination. The collected data embrace the metabolic processes in embryonic axes and whole seeds. The up-to-date results are integrated covering the main metabolic processes, namely water status and transport, protein and carbohydrate metabolism, antioxidant defense, axis-cotyledon relations, hormonal control and germination. Among the representatives of various taxa, the seeds of which exhibit recalcitrance, attention was given to horse chestnut seeds as one of most studied recalcitrants.
