Megalopta is able to discriminate between differently oriented dorsal black striped patterns, or an "artificial canopy" of black circles, and to use this information to locate its nest entrance. These results suggest that the local foliage patterns created by the canopy against the brighter sky could potentially provide the bee with reliable landmark information for navigation during foraging and homing at night.

In this present study, the authors evaluated the predictive factors for adverse maternal-fetal outcomes in pregnancies of women with cystic fibrosis (CF). Patients were followed up by a referral center for adults in southern Brazil.

This is a retrospective cohort study that used data from electronic medical records regarding pregnancies of women diagnosed with CF.

The study included 39 pregnancies related to 20 different women. The main adverse outcomes were high prevalence rates of premature birth (38.5%) and maternal respiratory exacerbation (84.6%). Lower body mass index (BMI) values (<20.8) and younger ages of CF diagnosis increased the risk of premature birth. The presence of methicillin-resistant and absence of methicillin-sensitive Staphylococcus aureus, as well as a younger age of diagnosis, increased the risk of maternal respiratory exacerbation during pregnancy.

Conception in women with CF is often associated with maternal and fetal complications. Continuous monitoring by a multidisciplinary team should emphasize appropriate nutritional status, investigation of bacterial colonization, and immediate attention to respiratory exacerbations.

To analyze gastroschisis annual incidence, mortality rates, and trends in the Brazilian state of Rio Grande do Sul from the year 2000 to the year 2017.

Population-based study with the analysis of the temporal trend of gastroschisis annual incidence and mortality rates. Data were obtained from the Live Birth Information System and the Mortality Information System, with the analysis performed by polynomial regression modeling.

There were 2,612,532 live births, 705 hospitalizations, and 233 deaths due to gastroschisis. selleck products The annual incidence of gastroschisis was 2.69 per 10,000 live births. The annual incidence rate increased by 85% in the total period (p=0.003), and mortality was 33% in the 2000-2017 period. Maternal age < 25 years was a risk factor for gastroschisis (p < 0.001). Children were more likely to be born weighing < 2,500 g (p < 0.001) and with a gestational age < 37 weeks (p < 0.001). The annual incidence trend was to increase, and the mortality trend was to decrease.

Similar to what has been described in several regions/countries, there was a trend showing an 85% increase in the annual incidence of gastroschisis (p=0.003) and the mortality was 33% with a trend of decreasing (p=0.002).

Although users of health-care services are important in providing input into decisions about research, the voices of people in prison are absent regarding research into their health. In this Health Policy paper, we present priorities for research into the health of people in prison according to people in prison themselves. By use of a deliberative research approach, citizens' juries were conducted in six prisons (three men's and three women's prisons) in Australia. Participants were selected following submissions of expression of interest forms that were distributed within the prisons. Prerecorded information by experts in the health of incarcerated people was shown to participants. Participants deliberated for up to 4 h before agreeing on five research priorities. All citizens' juries endorsed mental health as a number one research priority. Prison health-care services, alcohol and other drug use, education, and infectious diseases were identified as research priorities by most citizens' juries. Focal points within priorities included serious mental illness; grief and trauma; medication management; health-care service access, quality, and resources; drug withdrawal and peer support; prison-based needle and syringe programmes; and health and life skills education. If endeavours in research priority setting are to consider health equity goals, the views of our most health affected citizens need to be included.Molecular glues and proteolysis targeting chimeras (PROTACs) have emerged as small-molecule tools that selectively induce the degradation of a chosen protein and have shown therapeutic promise. Recently, several approaches employing light as an additional stimulus to control induced protein degradation have been reported. Here, we analyze the principles guiding the design of such systems, provide a survey of the literature published to date, and discuss opportunities for further development. Light-responsive degraders enable the precise temporal and spatial control of protein levels, making them useful research tools but also potential candidates for human precision medicine.A central quest in neuroscience is to gain a holistic understanding of all cell types in the brain. In this issue of Cell, Yao et al. establish a molecular architectural view of cell types across the entire adult mouse isocortex and hippocampal formation and reveal surprising similarities of cell types in these two brain regions.In this issue of Cell, Cui et al. demonstrate a previously unknown capacity for neutrophils to selectively kill cancer cells. How this killing is effected unfolds as a story of classical biochemistry, novel cell biology, and innate and adaptive immunity.
