Paspalum urvillei and Setaria parviflora are two plant species naturally adapted to iron-rich environments such as around iron mines wastes. The aim of our work was to characterize how these two species cope with these extreme conditions by comparing them with related model species, Oryza sativa and Setaria viridis, that appeared to be much less tolerant to Fe excess. Both Paspalum urvillei and Setaria parviflora were able to limit the amount of Fe accumulated within roots and shoots, compared to the less tolerant species. Perls/DAB staining of Fe in root cross sections indicated that Paspalum urvillei and Setaria parviflora responded through the build-up of the iron plaque (IP), suggesting a role of this structure in the limitation of Fe uptake. Synchrotron μXRF analyses showed the presence of phosphorus, calcium, silicon and sulfur on IP of Paspalum urvillei roots and μXANES analyses identified Fe oxyhydroxide (ferrihydrite) as the main Fe form. Once within roots, high concentrations of Fe were localized in the cell walls and vacuoles of Paspalum urvillei, Setaria parviflora and O. sativa whereas Setaria viridis accumulated Fe in ferritins. The Fe forms translocated to the shoots of Setaria parviflora were identified as tri-iron complexes with citrate and malate. In leaves, all species accumulated Fe in the vacuoles of bundle sheath cells and as ferritin complexes in plastids. TAK-243 purchase Taken together, our results strongly suggest that Paspalum urvillei and Setaria parviflora set up mechanisms of Fe exclusion in roots and shoots to limit the toxicity induced by Fe excess. Drought is one of the major constraints for soybean production in Brazil. In this study we investigated the physiological traits of two soybean parental genotypes under progressive soil drying and rewetting. The plants were evaluated under full irrigation (control) conditions and under water deficit imposed by suspending irrigation until the plants reached predawn leaf water potentials (Ψam) of -1.0 MPa (moderate) and -1.5 MPa (severe). Physiological analyses showed that these genotypes exhibit different responses to water deficit. The Embrapa 48 genotype reached moderate and severe water potential two days after the BR16 genotype and was able to maintain higher levels of A, ETR and ΦPSII even under deficit conditions. This result was not related to changes in gs, 13C isotopic composition and presence of a more efficient antioxidant system. In addition, Fv/Fm values did not decrease in Embrapa 48 genotype in relation to irrigated condition showing that stress was not causing photochemical inhibition of photosynthesis. The greater reduction in the relative growth of the shoots, with concomitant greater growth of the root system under drought, indicates that the tolerant genotype is able to preferentially allocated carbon to the roots, presenting less damage to photosynthesis. Therefore, the physiological responses revealed that the tolerant genotype postponed leaf dehydration by a mechanism involving a more efficient use and translocation of water from root to shoot to maintain cell homeostasis and photosynthetic metabolism under stress. Seed germination and early seedling development are two critical phases in plant lifecycle that largely determine crop yield. Phytohormones play an essential role in governing these developmental processes; of these, ethylene (ET; C2H4), the smallest gaseous hormone, plays a major role via crosstalk with other hormones. Typically, the mechanism of hormone (for instance, auxin, cytokinins, ET, and gibberellins) action is determined by cellular context, revealing either synergistic or antagonistic relations. Significant progress has been made, so far, on unveiling ET crosstalk with other hormones and environmental signals, such as light. In particular, stimulatory and inhibitory effects of ET on hypocotyl growth in light and dark, respectively, and its interaction with other hormones provide an ideal model to study the growth-regulatory pathways. In this review, we aim at exploring the mechanisms of multifarious phenomena that occur via ET crosstalk during the germination of seeds (overcoming dormancy), and all through the development of seedlings. Understanding the remarkably complex mechanism of ET crosstalk that emerges from the interaction between hormones and other molecular players to modulate plant growth, remains a challenge in plant developmental biology. Ground glass attenuation (GGA) of the lungs is a common finding of post-mortem computed tomography (PMCT) that is associated with pulmonary congestion and edema due to cardiac failure during the agonal period, or due to post-mortem hypostasis. However, hypo-attenuation of the lung is an atypical finding of PMCT, and is usually a consequence of hypovolemic states before death or postmortem body posture after death. Previous studies have shown a few differential diagnoses, such as hypothermia, massive hemorrhage, asphyxiation by hanging, and dehydration, for hypo-attenuation of the lung. This report presents the case of a woman who died suddenly because of an asthma attack. Our PMCT analysis demonstrated hypoattenuation of the lung in this case. We suggest fatal asthma as a differential diagnosis for the appearance of hypo-attenuation of lungs on PMCT. BACKGROUND Continuity models of midwifery care are rare in Sweden, despite its well-known positive effects. The aim was to describe pregnancy and birth outcome in women participating in a continuity of care project in a rural area of Sweden. METHOD A register-based study of 266 women recruited to the project and a control group of 125 women from the same catchment area. Midwives provided antenatal care and were on-call 7 a.m. to 11 p.m. for birth. Data were collected from the antenatal and birth records. Crude and adjusted odds ratios with 95% confidence intervals were calculated between women in the project and the control group. RESULTS There were more primiparous women and highly educated women recruited to the project, and fewer foreign-born and single women, compared to the control group. Women in the project met more midwives and were less likely to have a pregnancy complication. During intrapartum care, women recruited to the project were less likely to need labour augmentation and less likely to have an instrumental vaginal birth and elective caesarean section.
