The Chilean hazelnut (Gevuina avellana Mol., Proteaceae) is a southern South American nut consumed as a snack and included in different preparations of traditional Chilean cuisine. Recently we described the fatty acid profile, oxylipins, phenolic compounds, as well as the antioxidant capacity. The main compounds of the phenolic-enriched extract were only tentatively identified by spectrometric means. In the present work, we describe the isolation and full characterization of a cyclic dipeptide cyclo(Arg-Trp) and other compounds from the phenolic enriched extracts of the G. avellana cotyledons. Compounds were isolated by means of counter-current chromatography and structures were established by spectroscopic and spectrometric methods. This is the first report on small peptides in G. avellana and adds evidence on the possible beneficial effects of this nut in human health.A significant proportion of hypertension (potentially more than 5% in the general population) is due to primary aldosteronism (PA) which carries a worse prognosis when compared with blood pressure-matched essential hypertension. Effective targeted treatments are available which mitigate many of the cardiovascular complications of untreated PA. Despite this, the detection rate of PA in primary care is sub-optimal. In this review, we explore the challenges contributing to the under-diagnosis of PA in the community, including uncertainties regarding its actual prevalence. In order to detect PA early and offer targeted treatment before adverse cardiovascular consequences develop, routine screening for PA at the time of a diagnosis of hypertension would seem desirable. However, this is limited by a lack of studies to establish whether routine screening in primary care is cost-effective. Newer techniques are also being developed which could lessen the complexity of diagnosing PA. Most importantly, a dramatic increase in awareness of PA, as a treatable cause of hypertension, is needed amongst clinicians who manage hypertension.Complications following allogeneic hematopoietic cell transplantation (alloHCT) continue to be a significant challenge that often result in significant morbidity/mortality and increased healthcare utilization and cost. In this study, we analyzed the impact of post-alloHCT complications on healthcare utilization and cost during first year post-transplant. We analyzed data on 240 pediatric patients. Complications analyzed included kidney injury, liver injury, lung injury, viral infections, bacterial infections, fungal infections, and acute graft-versus-host disease (GVHD). Patients were divided into three groups based on the number of complications (0-1, 2-3, and >3). Cost was estimated from charges recorded in the Pediatric Health Information System database and hospital accounting records. Patients with >3 complications had higher healthcare utilization and cost, primarily driven by inpatient hospitalization and intensive care unit admissions. Multivariable analysis of risk factors identified bacteremia ($90,166, SE = 26,636, p  less then  0.001), lung injury ($108,529, SE = 28,196, p  less then  0.001), liver injury ($90,805, SE = 28,660, p = 0.002), and grade II-IV aGVHD ($137,866, SE = 28,472, p  less then  0.001) as associated with significantly increased cost. Our study highlights the significant impact complications have on the overall cost of alloHCT. The identification that complications associated with high morbidity (aGVHD, pulmonary disease) are also associated with the highest financial burden emphasizes the need for future research in these areas to expand management options and improve outcomes for our patients.Nectar is the most common floral reward for flower-visiting flies, bees, bats and birds. Many flowers hide nectar in the floral tube and preclude sensing of nectar by flower-visitors from a distance. Even in those flowers that offer easily accessible nectar, the nectaries are mostly inconspicuous to the human eye and the amount of nectar is sparse. It is widely accepted that many flowers display nectar guides in order to direct flower-visitors towards the nectar. Using false colour photography, covering ultraviolet, blue and green ranges of wavelength, revealed a yet unknown conspicuousness of nectar, nectaries and false nectaries for bees due to concordant reflection in the ultraviolet range of wavelength. iCRT14 purchase Nectars, many nectaries and false nectaries have glossy surfaces and reflect all incident light including UV-light. In most cases, this is not particularly conspicuous to the human eye, but highly visible for UV-sensitive insects, due to the fact that the glossy areas are often positioned in UV-absorbing central flower parts and thus produce a strong UV-signal. The optical contrast produced by the glossiness of small smooth areas in close proximity to nectar holders represents a widespread yet overlooked floral cue that nectarivorous flower-visitors might use to locate the floral nectar.Tahiti lemon juice (Citrus latifolia) (TLJ), as a natural source of flavonoids, has been used as an alternative to anti-inflammatory drugs for the treatment of dysmenorrhea and menstrual excessive bleeding, often associated with an imbalance of the prostaglandins (PG) levels. However, despite the positive effects, the mechanisms that rule menstruation control are still unknown. Therefore, the objectives were to characterize the TLJ and analyze its effect on the production of PGF2α, PGE2 and pro-inflammatory cytokines involved inmenstruation. Flavonoids from TLJ were discriminated by UPLC-DAD-MS/MS (Qq-TOF) and the effects of TLJ were studied in vitro by quantification of the contraction of myoblasts in culture and PGF2α and PGE2 productions. Further, the systemic and menstrual fluid levels of PGF2α, PGE2, IL-1β, TNF-α, IL-6, AK1B1 and AK1C3 enzymes produced by women during the menstrual period were compared after exposition or not to TLJ or meloxicam. The results showed that TLJ induces an increase in the contraction of myoblasts and the PGF2α supernatant level. Regarding in vivo analysis, a higher concentration of PGF2α and an unaltered PGE2 level was also found in the menstrual blood of women treated with TLJ, in contrast with a lower level of PGE2 and PGF2α observed in the meloxicam group. Concerning cytokines, only menstrual TNF-α levels decrease after treatment with TLJ or meloxicam. In conclusion, TLJ may favor the control of menstruation events via a PGF2α mediated muscle contractile response.
