Freeze injuries in olives are responsible for the ‘frostbitten olives’ sensory defect that is sometimes detected in virgin olive oil. This defect is becoming one of the most common negative ...attributes today because climate change has modified weather patterns. The temperature changes can take place abruptly, with rapid freeze–thaw cycles, or gradually. These changes produce significant alterations in the quality of the oils. This study analyzed the volatile composition of virgin olive oils characterized with ‘frostbitten olives’ defect. The volatile information allowed grouping these oils into two types characterized with two different profiles. One of them is characterized by ‘soapy’ and ‘strawberry-like’ perceptions and the presence of two volatile compounds (ethyl 2-methyl butanoate and ethyl propanoate). The second profile is characterized by ‘wood’ and ‘humidity’ descriptors and a high concentration of two volatiles (pentanal and octanal). These results on volatiles explain the existence of two sensory profiles associated with the ‘frostbitten olives’ defect.
Air pollution has been linked to adverse neonatal outcomes, mainly in the case of prolonged exposures. This study focuses on the short-term effects on maternal health.
We conducted a retrospective ...ecological time-series study in the Madrid Region covering the period 2013–2018. The independent variables were mean daily concentrations of tropospheric ozone (O3), particulate matter (PM10/PM2.5) and nitrogen dioxide (NO2), as well as noise levels. The dependent variables were daily emergency hospital admissions due to complications in pregnancy, childbirth and the puerperium. Poisson generalised linear regression models were fitted to quantify the relative and attributable risks, controlling for trend, seasonality, the autoregressive nature of the series, and a number of meteorological factors.
There were 318 069 emergency hospital admissions due to obstetric complications across the 2191 days of study. Of this total: 13 164 (95%CI: 9930–16 398) admissions were attributable to exposure to O3, the only pollutant to show a statistically significant (p < 0.05) association with admissions due to hypertensive disorders; and 10 575 (95%CI: 3573–17 566) admissions were attributable to daytime noise levels, while admissions due to hyperemesis gravidarum and vomiting were related to exposure to night noise. Other pollutants which also displayed statistically significant associations were: NO2 concentrations, with admissions due to vomiting and preterm labour; PM10 concentrations, with premature rupture of membranes: and PM2.5 concentrations, with total complications.
Exposure to a range of air pollutants, and ozone in particular, is associated with a higher number of emergency hospital admissions due to gestational complications. Hence, surveillance of environmental effects on maternal health should be intensified, and plans and strategies to minimise these should be drawn up.
•O3 and noise are associated with emergency hospital admissions for gestational complications.•4.1% (95%CI: 3.1–5.2) of the hospital admissions were attributable to O3.•3.3% (95%CI: 1.1–5.5) of the hospital admissions were attributable to noise.
Cyclin D1 promotes cell cycle progression during G1 phase, a key event in G1‐S transition. The protein is encoded by gene CCND1, located in chromosomal band 11q13. Cyclin D1 plays key roles in cell ...biology, including cell proliferation and growth regulation, mitochondrial activity modulation, DNA repair, and cell migration control. CCND1 gene and its protein cyclin D1 are frequently altered by different molecular mechanisms, including amplification, chromosomal translocations, mutations, and activation of the pathways involved in cyclin D1 expression, alterations which appear to be essential in the development of human cancers, including oral carcinoma. This is the first published review of the specific features of cyclin D1 overexpression in oral oncogenesis. Starting with the physiological regulation of cyclin D1, there is an evaluation of its functions, overexpression mechanisms, and the implications of the oncogenic activation of CCND1/cyclin D1 in oral squamous cell carcinoma. The potential diagnostic and prognostic value of cyclin D1 is reviewed. The influence of CCND1/cyclin D1 on tumor size and clinical stage is reported, and an update is provided on the utilization of cyclin D1 as therapeutic target and on the combination of cyclin D1 inhibitors with cytotoxic agents. Future research lines in this field are also proposed.
Introduction
The incidence of suicide is much higher in people with mental health disorders, estimating that up to 9 out of 10 people who commit suicide suffer from at least one of them. For this ...reason, suicide is considered by many authors as the most serious complication of psychiatric disorders. The literature and the experience of clinicians support the potential usefulness of specific measures and programs aimed at its prevention.
Objectives
Congruently, throughout the last decade, consecutive strategic mental health plans in the Autonomous Community of Madrid, Spain, have included suicide prevention plans among their priorities, setting the objective of reducing suicidal behavior in the population of Madrid by implementing practical measures in the healthcare system.
Methods
In the presented work we aim to summarize the multidisciplinary therapeutic process in the context of this program and the results obtained during its years of experience.
Results
Retiro Community Mental Health Treatment Center launched a specific program in 2013 to meet these objectives. This initiative, that received the name PRISURE (Spanish acronym for Suicide Risk Prevention Program in Retiro), is an outpatient intervention program for immediate care, as the first appointment is scheduled within a week after referral. Intensive, comprehensive and multidisciplinary care is provided for patients with moderate to severe suicide risk.
Conclusions
All professional categories that work in the Community Mental Health Treatment Center actively participate. In parallel with clinical performance, these professionals also carry out coordination tasks with other entities that are dedicated to suicide prevention, as well as with patients’ and families’ associations.

Abstract The main objective of this study is to understand the differences in equilibrium control between normal subjects and those with Down syndrome. A total of 54 subjects participated ...voluntarily, divided into control group and Down syndrome group. The equilibrium of the subjects was tested under two conditions: bipedal support with eyes open and closed. The signals were analyzed in a time and frequency domain. The statistical parameters selected (i.e., RMS distance, mean velocity, mean frequency and sway area) to analyze the behavior of the center of pressures (CoP) are calculated employing the result of the combination of the time series data in both directions (i.e. resultant distance). In order to calculate the frequency bands produced by the displacements of the CoP, a Fast Fourier Transform of the data was performed. The group with Down syndrome showed poorer static equilibrium control than the control group in the time domain. In the frequency domain, we found differences between the groups in the distribution of energy in the frequency bands analyzed. In addition, we observed the existence of an interaction effect of the group and the condition tested ( p < 0.001). These findings show that in the absence of visual information, the control group increases the energy at low frequencies, while the group with Down syndrome decreases it. Additionally, the lower amount of energy observed in this band under the ‘eyes closed’ condition may serve to identify abnormalities in the functioning of the vestibular apparatus of individuals with Down syndrome and/or difficulties experienced by these individuals in extracting relevant information from this route.
This paper provides a brief review of the most significant characteristics of olive oil. Processing, composition, authentication, sensory quality and health benefits are the examined aspects. In all ...these issues, the most recent challenges are described, most of them related to new environmental problems, emerging procedures of adulteration and new chemical features to detect them, and a deep knowledge of the relationship between olive oil consumption and the incidence of some diseases other than cardiovascular malfunction.
Bioactive peptides derived from diverse food proteins have been part of diverse investigations. Whey is a rich source of proteins and components related to biological activity. It is known that ...proteins have effects that promote health benefits. Peptides derived from whey proteins are currently widely studied. These bioactive peptides are amino acid sequences that are encrypted within the first structure of proteins, which required hydrolysis for their release. The hydrolysis could be through in vitro or in vivo enzymatic digestion and using microorganisms in fermented systems. The biological activities associated with bio-peptides include immunomodulatory properties, antibacterial, antihypertensive, antioxidant and opioid, etc. These functions are related to general conditions of health or reduced risk of certain chronic illnesses. To determine the suitability of these peptides/ingredients for applications in food technology, clinical studies are required to evaluate their bioavailability, health claims, and safety of them. This review aimed to describe the biological importance of whey proteins according to the incidence in human health, their role as bioactive peptides source, describing methods, and obtaining technics. In addition, the paper exposes biochemical mechanisms during the activity exerted by biopeptides of whey, and their application trends.
•Individuals reporting childhood trauma are more likely to display suicidal behavior.•Variability in CRH-BP and FKBP5 genes confers susceptibility for suicidal behavior.•Interaction between childhood ...trauma and HPA axis genes variability is not found.
Around 8% of bipolar disorder (BD) patients die by suicide every year, accounting for the highest rate among the psychiatric population. Suicidal behavior (SB) is mediated by an intertwining system of extrinsic and intrinsic factors. Childhood trauma (CT) and gene variants of the stress-management hypothalamic-pituitary-adrenal (HPA) axis have been reported as risk factors for SB. The aim of this study was to elucidate the association of CT and HPA axis genetic variants with SB.
135 BD patients were recruited for clinical assessment of CT and SB by means of the Childhood Trauma Questionnaire (CTQ) and the Columbia Suicide Severity Rating Scale (C-SSRS), respectively. A total of 28 single nucleotide polymorphisms (SNPs) from 8 HPA axis genes (POMC, NR3C2, CRH-BP, NR3C1, FKBP5, CRHR2, CRHR1, and MC2R) were genotyped.
The analyses showed an association of total CTQ score (p = 0.003), emotional abuse (p = 0.001), sexual abuse (p = 0.005) and emotional neglect (p = 0.005) with SB. CRH-BP rs7728378-C carriers (p = 0.004; OR = 3.05), FKBP5 rs3777747-AA (p = 0.039; OR = 0.34) and FKBP5 rs2766533-GG genotypes (p = 0.001; OR = 2.93) were associated with SB although only rs2766533 survived multiple test correction. No gene-environment interaction was found.
The relatively small sample size limits the statistical power to detect smaller environmental and genetic effects. Cross-sectional data collection in psychometric assessments can yield biased data.
The present study characterizes novel SB risk factors and replicates previous findings in BD patients. CT and variability in CRH-BP and FKBP5 genes should be further studied for a better understanding of SB and ultimately help in suicide prevention.
Blood extraction is extremely important for the development of scientific research; however, the existing methods for amphibian´s blood sampling are invasive, mainly leading to the euthanasia of the ...animal. Therefore, less intrusive methods that allow the obtention of multiple samples from the same individual, are needed as an alternative to the common methods available. Hence, the aim of this study was to propose a minimally invasive method for obtaining blood from the hind leg of Xenopus laevis, that allows continuous sampling without compromising the wellbeing of the organisms. With this method, it was possible to extract blood and plasma from adults and juveniles, and the amount of sample was enough to perform biochemical and molecular assays to assess the viability of the blood. The results also revealed that this method is a convenient alternative to obtain blood without affecting the welfare of the experimental organisms, avoiding the cull of the animals, and the samples are viable for their use in follow up studies.
