Kale is a group of diverse Brassicaceae species that are nutritious leafy greens consumed for their abundance of vitamins and micronutrients. Typified by their curly, serrated and/or wavy leaves, kale varieties have been primarily defined based on their leaf morphology and geographic origin, despite having complex genetic backgrounds. Kale is a very promising crop for vertical farming due to its high nutritional content; however, being a non-model organism, foundational, systems-level analyses of kale are lacking. Previous studies in kale have shown that time-of-day harvesting can affect its nutritional composition. Therefore, to gain a systems-level diel understanding of kale across its wide-ranging and diverse genetic landscape, we selected nine publicly available and commercially grown kale cultivars for growth under near-sunlight LED light conditions ideal for vertical farming. We then analyzed changes in morphology, growth and nutrition using a combination of plant phenotyping, proteomics and metabolomics. As the diel molecular activities of plants drive their daily growth and development, ultimately determining their productivity as a crop, we harvested kale leaf tissue at both end-of-day (ED) and end-of-night (EN) time-points for all molecular analyses. Our results reveal that diel proteome and metabolome signatures divide the selected kale cultivars into two groups defined by their amino acid and sugar content, along with significant proteome differences involving carbon and nitrogen metabolism, mRNA splicing, protein translation and light harvesting. Together, our multi-cultivar, multi-omic analysis provides new insights into the molecular underpinnings of the diel growth and development landscape of kale, advancing our fundamental understanding of this nutritious leafy green super-food for horticulture/vertical farming applications., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Scandola, Mehta, Castillo, Boyce and Uhrig.)

Plants are able to sense changes in their light environments, such as the onset of day and night, as well as anticipate these changes in order to adapt and survive. Central to this ability is the plant circadian clock, a molecular circuit that precisely orchestrates plant cell processes over the course of a day. REVEILLE (RVE) proteins are recently discovered members of the plant circadian circuitry that activate the evening complex and PSEUDO-RESPONSE REGULATOR genes to maintain regular circadian oscillation. The RVE8 protein and its two homologs, RVE 4 and 6 in Arabidopsis (Arabidopsis thaliana), have been shown to limit the length of the circadian period, with rve 4 6 8 triple-knockout plants possessing an elongated period along with increased leaf surface area, biomass, cell size, and delayed flowering relative to wild-type Col-0 plants. Here, using a multi-omics approach consisting of phenomics, transcriptomics, proteomics, and metabolomics we draw new connections between RVE8-like proteins and a number of core plant cell processes. In particular, we reveal that loss of RVE8-like proteins results in altered carbohydrate, organic acid, and lipid metabolism, including a starch excess phenotype at dawn. We further demonstrate that rve 4 6 8 plants have lower levels of 20S proteasome subunits and possess significantly reduced proteasome activity, potentially explaining the increase in cell-size observed in RVE8-like mutants. Overall, this robust, multi-omic dataset provides substantial insight into the far-reaching impact RVE8-like proteins have on the diel plant cell environment., (© American Society of Plant Biologists 2022.

Hildegard of Bingen (1098-1179AD) is one of the most relevant figures of the Middle Ages. She wrote two medical books, Physica (Natural history) and Causae et curae (Causes and remedies). Our aim was to provide a comprehensive account of Hildegard of Bingen's conception of epilepsy, of the remedies proposed to treat it, and of the medical and physiological theories behind their use. We searched Hildegard of Bingen's entire body of writings to identify any possible reference to epilepsy or epileptic seizures. We reported the identified passages referring to epilepsy and discussed their content in light of medieval medical and physiological theories. Most references to epilepsy were found in Physica and Causae et curae. The suggested remedies against epilepsy range from herbal preparations to animal remedies and jewel therapy. Hildegard's conception of epilepsy gives the impression of an original revisitation of the traditional theory of humors, and carries strong moral connotations. Hildegard of Bingen's conception of epilepsy appears strongly rooted in medieval thinking and less in physiological theories. However, it differs in many respects to the traditional medieval beliefs and is a further proof of her unique personality. As living testimony of the past, Hildegard's writings enable us to shed a fascinating light on the beliefs concerning epilepsy in the middle ages., (Copyright © 2017 Elsevier Inc.

Respiration is a vital, complex function, fundamentally automatic that can be modulated by will. The aim of the original method submitted is the progressive rehabilitation of the patient to strain, by a gradual reduction of respiratory frequency at the progressive increase in expiration phases and the execution of a growing effort in strict relation to the execution of the method itself. The patient learns to beat out the rhythm of his respiration based upon the strokes of the metronome, calibrated at 60 strokes a minute. The most evident documentation of the efficacy of our method of voluntary regularization of the respiratory act is in the evaluation of the effort capacity of each patient, before and after the method. The data are referred to the distance covered by cyclette, in standard conditions. The examined clinical parametres comprehend: cardiac frequency, respiratory frequency, maximal pause and arterial pressure. The laboratory parametres examined include the value of the arterial astrup: pH, pCO2, HCO3-, total CO2, pO2, excess basis. The scarcity of clinical survey examined during our research does not permit the formulation of any conclusive considerations, which would lead to a critical revision of the whole field of the physiology of respiration. For this reason, it is more prudent to establish the modifications of various parametres collected, until a more certain and wider confirmation is available.
