There is increasing experimental evidence that strigolactones, a class of carotenoid-derived sesquiterpenoid hormones, and their downstream signal components play a role in plant resilience to abiotic stress. Strigolactones positively influence plant coping mechanisms in response to abiotic stressors like drought and high salinity. In this study, we examined the effects of rac-GR24 (a synthetic strigolactone analog) and strigolactone inhibitors on the physiological and molecular responses associated with thermotolerance during seed germination and seedling development in Lupinus angustifolius under heat stress. Photosystem I & II functions were also evaluated via Chl a fluorescence transient analysis in heat stressed lupine seedlings. Our results suggest a putative role for GR24 in mediating tolerance to heat stress during seed germination and seedling development albeit these responses appeared independent of D14-mediated signalling. Seeds primed with GR24 had the highest of all germination indices, enhanced proline content and reduced peroxidation of lipids. GR24 also enhanced the activities of enzymes of the antioxidant and glyoxalase systems in lupine seedlings. selleck compound The JIP-test indicated that GR24 conferred resistance to heat stress-induced damage to the oxygen evolution complex while also preventing the inactivation of PSII reaction centres thus ensuring PSII thermotolerance.National clinical quality registries (CQRs) are effective tools for improving the outcomes of patients admitted to the intensive care unit (ICU), and are increasingly important as healthcare needs evolve. A high-quality ICU CQR is built from a foundation of common requirements and challenges. First, performance indicators of the structure, process, or outcomes of patient care should measure what is important. Second, high data quality is essential and can be collected and curated through standardized processes. Third, standardized mortality ratio (SMR) is a cornerstone for benchmarking ICU performance, but application requires a comprehensive understanding of its context and potential pitfalls. Fourth, data collection alone is insufficient. Quality improvement comes from closing the feedback loop by identifying and managing unwarranted practice variation. Fifth, the process of improving healthcare is fundamentally a human enterprise, subject to behavioural change, including those that modify performance. Sixth, ICU CQRs must be dynamic to meet the needs of an evolving healthcare system and stakeholders. Finally, these lessons are far from comprehensive. Sharing perspectives on the development of ICU CQRs can help maximise their value as a powerful platform for informing policy development and improving the outcomes of patients admitted to the ICU.The digitalization of the Intensive Care Unit (ICU) led to an increasing amount of clinical data being collected at the bedside. The term "Big Data" can be used to refer to the analysis of these datasets that collect enormous amount of data of different origin and format. Complexity and variety define the value of Big Data. In fact, the retrospective analysis of these datasets allows to generate new knowledge, with consequent potential improvements in the clinical practice. Despite the promising start of Big Data analysis in medical research, which has seen a rising number of peer-reviewed articles, very limited applications have been used in ICU clinical practice. A close future effort should be done to validate the knowledge extracted from clinical Big Data and implement it in the clinic. In this article, we provide an introduction to Big Data in the ICU, from data collection and data analysis, to the main successful examples of prognostic, predictive and classification models based on ICU data. In addition, we focus on the main challenges that these models face to reach the bedside and effectively improve ICU care.Peach (Prunus persica L.) fruit are highly susceptible to chilling injury during cold storage, resulting in internal flesh browning and a failure to soften normally. We have examined the effect of a postharvest treatment consisting of a brief (30 s) dip in the natural plant hormone jasmonic acid, prior to storage at 4 °C. Jasmonic acid treatment reduced the severity of internal flesh browning and did not inhibit fruit softening over a 35 d storage period. Two major physiological effects of jasmonic acid on the fruit were observed, an increase in ethylene production and a prevention of the decline in soluble sugar content seen in controls. An increased soluble sugar content may have multiple benefits in resisting chilling stress, scavenging reactive oxygen species and acting to stabilize membranes. Our results show that a treatment with jasmonic acid can enhance chilling tolerance of peach fruit by regulating ethylene and sugar metabolism.
Coronavirus disease 2019 (COVID-19) causes a hypercoagulable state. Several autopsy studies have found microthrombi in pulmonary circulation.

In this randomized, open-label, phase II study, we randomized COVID-19 patients requiring mechanical ventilation to receive either therapeutic enoxaparin or the standard anticoagulant thromboprophylaxis. We evaluated the gas exchange over time through the ratio of partial pressure of arterial oxygen (PaO2) to the fraction of inspired oxygen (FiO2) at baseline, 7, and 14days after randomization, the time until successful liberation from mechanical ventilation, and the ventilator-free days.

Ten patients were assigned to the therapeutic enoxaparin and ten patients to prophylactic anticoagulation. There was a statistically significant increase in the PaO2/FiO2 ratio over time in the therapeutic group (163 [95% confidence interval - CI 133-193] at baseline, 209 [95% CI 171-247] after 7days, and 261 [95% CI 230-293] after 14days), p=0.0004. In contrast, we did not observe this improvement over time in the prophylactic group (184 [95% CI 146-222] at baseline, 168 [95% CI 142-195] after 7days, and 195 [95% CI 128-262] after 14days), p=0.487. Patients of the therapeutic group had a higher ratio of successful liberation from mechanical ventilation (hazard ratio 4.0 [95% CI 1.035-15.053]), p=0.031 and more ventilator-free days (15days [interquartile range IQR 6-16] versus 0days [IQR 0-11]), p=0.028 when compared to the prophylactic group.

Therapeutic enoxaparin improves gas exchange and decreases the need for mechanical ventilation in severe COVID-19.
