Temperature has an overriding role compared to photoperiod in regulating the seasonal timing of winter moth egg hatching.

To accurately predict species' phenology under climate change, we need to gain a detailed mechanistic understanding of how different environmental cues interact to produce the seasonal timing response. In the winter moth (Operophtera brumata), seasonal timing of egg hatching is strongly affected by ambient temperature and has been under strong climate change-induced selection over the past 25 years. However, it is unclear whether photoperiod received at the egg stage also influences timing of egg hatching.

Atrial thrombi in elective patients considered for atrial fibrillation rhythm control: Risk factors and prognostic value.

The prognostic value of atrial thrombi (AT) among elective patients with atrial fibrillation (AF) referred for a rhythm control strategy is unclear. In this study, clinical variables were correlated with the presence of AT and long term survival among 205 patients submitted to transesophageal echocardiography before elective AF cardioversion or ablation. Atrial thrombi were present in 7.

Latitudinal Variation in Circadian Rhythmicity in .

Many physiological processes of living organisms show circadian rhythms, governed by an endogenous clock. This clock has a genetic basis and is entrained by external cues, such as light and temperature. Other physiological processes exhibit seasonal rhythms, that are also responsive to light and temperature.

Up to 15-Year Survival of Men and Women after Percutaneous Coronary Intervention Paid by the Brazilian Public Healthcare System in the State of Rio de Janeiro, 1999-2010.

Background: Percutaneous coronary intervention (PCI) is the most frequently used invasive therapy for ischemic heart disease (IHD). Studies able to provide information about PCI's effectiveness should be conducted in a population of real-world patients.

Objectives: To assess the survival rate of IHD patients treated with PCI in the state of Rio de Janeiro (RJ).

Complications after elective percutaneous coronary interventions: A comparison between public and private hospitals.

Objective: Complications after percutaneous coronary interventions (PCI) are associated with significant morbidity and mortality, although institutional discrepancies can occur when public and private hospitals coexist within the healthcare system. The aim of this study was to compare the in-hospital complication rates and mortality in addition to long-term survival following elective PCI in two reference public and private cardiology hospitals in Rio de Janeiro, Brazil.

Methods: From January 1st 2013 to December 31st 2014, a total of 440 procedures were identified in both hospitals (public: 328 vs.

Chronobiology of interspecific interactions in a changing world.

Animals should time activities, such as foraging, migration and reproduction, as well as seasonal physiological adaptation, in a way that maximizes fitness. The fitness outcome of such activities depends largely on their interspecific interactions; the temporal overlap with other species determines when they should be active in order to maximize their encounters with food and to minimize their encounters with predators, competitors and parasites. To cope with the constantly changing, but predictable structure of the environment, organisms have evolved internal biological clocks, which are synchronized mainly by light, the most predictable and reliable environmental cue (but which can be masked by other variables), which enable them to anticipate and prepare for predicted changes in the timing of the species they interact with, on top of responding to them directly.

Troponin I elevation after elective percutaneous coronary interventions: Prevalence and risk factors.

Troponin elevation after coronary angioplasty is a prognostic marker associated with significant morbidity and mortality, although its prevalence varies according to clinical and procedural characteristics. We analyzed the frequency of post-procedural enzyme elevation among 112 elective interventions between 2013 and 2014 in a private hospital in Brazil. Troponin increase was observed in 62.

Troponin I elevation and all-cause mortality after elective percutaneous coronary interventions.

Background/purpose: Although troponin I (TnI) elevation and myocardial injury after percutaneous coronary interventions (PCI) are frequent findings, their prognoses remain controversial. We aimed to determine the association between any or ≥5 times TnI elevation after elective PCI and subsequent one year mortality rates and long term survival.

Methods: Consecutive patients admitted for elective PCI between January 2013 and December 2014 were retrospectively analyzed by chart review in two hospitals in Rio de Janeiro.

QTL analysis of the photoperiodic response and clinal distribution of period alleles in Nasonia vitripennis.

In seasonal environments, organisms synchronize their life cycle with the annual cycle of environmental factors. In many insect species, this includes a diapause response: a timed dormant stage that allows to survive harsh winter conditions. Previously, we have shown that larval diapause in the parasitic wasp Nasonia vitripennis is induced by the mother upon exposure to a threshold number of short photoperiods (named switch point) and diapause response follows a latitudinal cline in natural populations.

The Genome of Winter Moth (Operophtera brumata) Provides a Genomic Perspective on Sexual Dimorphism and Phenology.

The winter moth (Operophtera brumata) belongs to one of the most species-rich families in Lepidoptera, the Geometridae (approximately 23,000 species). This family is of great economic importance as most species are herbivorous and capable of defoliating trees. Genome assembly of the winter moth allows the study of genes and gene families, such as the cytochrome P450 gene family, which is known to be vital in plant secondary metabolite detoxification and host-plant selection.

Cardiovascular mortality among a cohort of hypertensive and normotensives in Rio de Janeiro - Brazil - 1991-2009.

Background: Although there is strong evidence of the benefits of antihypertensive treatment, the high prevalence of this important cardiovascular risk factor and its complications, as well as the low control rates of hypertension observed in many studies justify the investigation of these relationships in population studies. The objective was to investigate the ratio of cardiovascular disease mortality between hypertensives (non-treated, controlled and uncontrolled) and non-hypertensives in a cohort of a population sample of adults living in Ilha do Governador, Rio de Janeiro state, Brazil, who were classified in a survey conducted in 1991 and 1992 and whose death certificates were sought 19 years later.

Methods: A cohort study was performed on probabilistic linkage between data from an epidemiological study of hypertension performed in Ilha do Governador, in Rio de Janeiro, Brazil (1991 to 1992) and data from the Mortality Information System of Rio de Janeiro (1991 to 2009).

Survival and predictive factors of lethality in hemodialysis: D/I polymorphism of the angiotensin I-converting enzyme and of the angiotensinogen M235T genes.

Background: End-stage kidney disease patients continue to have markedly increased cardiovascular disease morbidity and mortality. Analysis of genetic factors connected with the renin-angiotensin system that influences the survival of the patients with end-stage kidney disease supports the ongoing search for improved outcomes.

Objective: To assess survival and its association with the polymorphism of renin-angiotensin system genes: angiotensin I-converting enzyme insertion/deletion and angiotensinogen M235T in patients undergoing hemodialysis.

Socioeconomic aspects of spousal concordance for hypertension, obesity, and smoking in a community of Rio de Janeiro, Brazil.

Objective: The present study aims to evaluate the environmental role in the distribution of hypertension, obesity, and smoking and spousal concordance for the presence/absence of these 3 cardiovascular risk factors.

Methods: A cross-sectional study was conducted in a community in Rio de Janeiro, Brazil. The households were randomly selected.
