Heat stress reduces stomatal numbers in Ginkgo biloba: Implications for the stomatal method of palaeo-atmospheric [CO] reconstruction during episodes of global warming.

The stomata of fossil plants are commonly used as proxies to reconstruct palaeo-atmospheric carbon dioxide concentrations (palaeo-[CO]). Stomatal reconstruction of palaeo-[CO] during global greenhouse periods or episodes of global warming, are particularly important to our understanding of the role of CO as a climate system driver. However, the efficacy of the 'stomatal method' for palaeo-[CO] reconstruction depends upon the strength of the inverse relationship between stomatal number and the [CO] in which the leaf developed.

All the clinical questions were discussed by the expert panel in multiple rounds through the Delphi approach and, for each statement, a consensus among the experts was reached.

Nociception level index variations in ICU: curarized vs non-curarized patients - a pilot study.

Purpose: Pain is a major physiological stressor that can worsen critical medical conditions in many ways. Currently, there is no reliable monitoring tool which is available for pain monitoring in the deeply sedated ± curarized critically ill patients. This study aims to assess the effectiveness of the multiparameter nociception index (NOL®) in the critical care setting.

Psychometric properties of the Quiet Ego Scale (iQES) within the Italian cultural context.

Introduction: The quiet ego indicates a more compassionate conception of self-identity that integrates others into the self by lowering the intensity of the ego and enhancing the awareness of the present moment. The Quiet Ego Scale (QES) is a 14-item self-report measure of quiet ego, and it is composed of the following four psychological domains: detached awareness, inclusive identity, perspective taking, and growth. The present study aimed to test the psychometric properties of the Quiet Ego Scale within the Italian cultural context (iQES).

Plant Physiological Analysis to Overcome Limitations to Plant Phenotyping.

Plant physiological status is the interaction between the plant genome and the prevailing growth conditions. Accurate characterization of plant physiology is, therefore, fundamental to effective plant phenotyping studies; particularly those focused on identifying traits associated with improved yield, lower input requirements, and climate resilience. Here, we outline the approaches used to assess plant physiology and how these techniques of direct empirical observations of processes such as photosynthetic CO assimilation, stomatal conductance, photosystem II electron transport, or the effectiveness of protective energy dissipation mechanisms are unsuited to high-throughput phenotyping applications.

Characterization of artisanal saffron ricotta cheese produced in Sicily: Physicochemical, microbiological, sensory, and antioxidant characteristics.

The present study aims to characterize the artisanal saffron ricotta cheese produced from the whey of Piacentinu Ennese protected designation of origin (PDO) cheesemaking, including via technological parameters detected during the production process and by assessment of the main physicochemical, microbial, sensory, and antioxidant characteristics. A survey on the manufacture process of saffron and control ricotta cheese was conducted on 3 farms, located in the production area of the Piacentinu Ennese PDO cheese. pH and temperature followed a specific behavior, characterized by an inverse trend where pH decreased and temperature increased, playing an important role in the production process.

The 'microbiome counterattack': Insights on the soil and root-associated microbiome in diverse chickpea and lentil genotypes after an erratic rainfall event.

Legumes maintain soil fertility thanks to their associated microbiota but are threatened by climate change that causes soil microbial community structural and functional modifications. The core microbiome associated with different chickpea and lentil genotypes was described after an unexpected climatic event. Results showed that chickpea and lentil bulk soil microbiomes varied significantly between two sampling time points, the first immediately after the rainfall and the second 2 weeks later.

Metabolic Background, Not Photosynthetic Physiology, Determines Drought and Drought Recovery Responses in C3 and C2 Moricandias.

Distinct photosynthetic physiologies are found within the genus, both C3-type and C2-type representatives being known. As C2-physiology is an adaptation to drier environments, a study of physiology, biochemistry and transcriptomics was conducted to investigate whether plants with C2-physiology are more tolerant of low water availability and recover better from drought. Our data on (Mmo, C3), (Mav, C2) and (Msu, C2) show that C3 and C2-type are metabolically distinct under all conditions tested (well-watered, severe drought, early drought recovery).

The functional significance of the stomatal size to density relationship: Interaction with atmospheric [CO] and role in plant physiological behaviour.

The limits for stomatal conductance are set by stomatal size (SS) and density (SD). An inverse relationship between SS and SD has been observed in fossil and living plants. This has led to hypotheses proposing that the ratio of SS to SD influences the diffusion pathway for CO and degree of physiological stomatal control.

The evolution of diffusive and biochemical capacities for photosynthesis was predominantly shaped by [CO] with a smaller contribution from [O].

The atmospheric concentration of carbon dioxide ([CO]) and oxygen ([O]) directly influence rates of photosynthesis (P) and photorespiration (R) through the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO). Levels of [CO] and [O] have varied over Earth history affecting rates of both CO uptake and loss, alongside associated transpirative water-loss. The availability of CO has likely acted as a stronger selective pressure than [O] due to the greater specificity of RubisCO for CO.

Morpho-Physiological Classification of Italian Tomato Cultivars ( L.) According to Drought Tolerance during Vegetative and Reproductive Growth.

Irrigation is fundamental for agriculture but, as climate change becomes more persistent, there is a need to conserve water and use it more efficiently. It is therefore crucial to identify cultivars that can tolerate drought. For economically relevant crops, such as tomatoes, this purpose takes on an even more incisive role and local agrobiodiversity is a large genetic reservoir of promising cultivars.

Photoprotective Role of Photosynthetic and Non-Photosynthetic Pigments in : Is Their "Antioxidant" Function Prominent in Leaves Exposed to Severe Summer Drought?

Carotenoids and phenylpropanoids play a dual role of limiting and countering photooxidative stress. We hypothesize that their "antioxidant" function is prominent in plants exposed to summer drought, when climatic conditions exacerbate the light stress. To test this, we conducted a field study on , a Mediterranean evergreen shrub, carrying out daily physiological and biochemical analyses in spring and summer.

Integrating stomatal physiology and morphology: evolution of stomatal control and development of future crops.

Stomata are central players in the hydrological and carbon cycles, regulating the uptake of carbon dioxide (CO) for photosynthesis and transpirative loss of water (HO) between plants and the atmosphere. The necessity to balance water-loss and CO-uptake has played a key role in the evolution of plants, and is increasingly important in a hotter and drier world. The conductance of CO and water vapour across the leaf surface is determined by epidermal and stomatal morphology (the number, size, and spacing of stomatal pores) and stomatal physiology (the regulation of stomatal pore aperture in response to environmental conditions).

Noninvasive Ventilatory Support of Patients with COVID-19 outside the Intensive Care Units (WARd-COVID).

Treatment with noninvasive ventilation (NIV) in coronavirus disease (COVID-19) is frequent. Shortage of intensive care unit (ICU) beds led clinicians to deliver NIV also outside ICUs. Data about the use of NIV in COVID-19 is limited.

[Cognitive-Behavioural group interventions and Multifamily Psychoanalysis group in a Psychiatric Ward].

Aim: This paper aims to study, evaluate and compare the effectiveness of two group interventions within a Psychiatric Intensive Care Unit (PICU). The outcome indicators of the satisfaction of patients and their families with the ward were evaluated with a Satisfaction Questionnaire on the department, and their satisfaction with the groups were evaluated with the Satisfaction Questionnaire for the groups. The two theoretical orientations examined are the cognitive-behavioural therapy, with group cognitive-behavioural intervention in the context of SPDC, and psychoanalysis, with multifamily psychoanalysis groups, according to the model of Jorge García Badaracco.

Life-long individual planning in children with developmental disability: the active role of parents in the Italian experience.

Many young adults with neurodevelopmental disorders experience poor transition outcomes in key areas, including employment, health care, and independent living. Innovative welfare models highlight the importance of involving the local community, and in particular the parents, as important stakeholders capable to generate services and affect local economy. As indicated by the World Health Organization, the availability of person-centered responses, also providing a health budget, appears to be the basis for taking into account person's rights to self-determination.

Seasonal and daily variations in primary and secondary metabolism of three maquis shrubs unveil different adaptive responses to Mediterranean climate.

Maquis species play a central role in the maintenance of coastal ecosystems thanks to anatomical, physiological and biochemical features evolved to cope with severe stress conditions. Because the seasonal and daily dynamics of physiological and biochemical traits of maquis species are not fully addressed, we performed a field study on three coexisting Mediterranean shrubs ( L. and L.

A Comparison of the Variable J and Carbon-Isotopic Composition of Sugars Methods to Assess Mesophyll Conductance from the Leaf to the Canopy Scale in Drought-Stressed Cherry.

Conductance of CO across the mesophyll () frequently constrains photosynthesis () but cannot be measured directly. We examined of cherry ( L) subjected to severe drought using the variable method and carbon-isotopic composition (C) of sugars from the centre of the leaf, the leaf petiole sap, and sap from the largest branch. Depending upon the location of the plant from which sugars are sampled, may be estimated over scales ranging from a portion of the leaf to a canopy of leaves.

Dynamic changes in ABA content in water-stressed Populus nigra: effects on carbon fixation and soluble carbohydrates.

Background And Aims: Hydraulic and chemical signals operate in tandem to regulate systemic plant responses to drought. Transport of abscisic acid (ABA) through the xylem and phloem from the root to shoot has been suggested to serve as the main signal of water deficit. There is evidence that ABA and its ABA-glycosyl-ester (ABA-GE) are also formed in leaves and stems through the chloroplastic 2-C-methylerythritol-5-phosphate (MEP) pathway.

The effect of summer drought on the yield of Arundo donax is reduced by the retention of photosynthetic capacity and leaf growth later in the growing season.

Background And Aims: The development of Arundo donax as a biomass crop for use on drought-prone marginal lands in areas with warm to hot climates is constrained by the lack of variation within this species. We investigated the effect of morphological and physiological variation on growth and tolerance to drought under field conditions in three ecotypes of A. donax collected from habitats representing a climate gradient: a pre-desert in Morocco, a semi-arid Mediterranean climate in southern Italy and a warm sub-humid region of central Italy.

The Impact of Heat Stress and Water Deficit on the Photosynthetic and Stomatal Physiology of Olive ( L.)-A Case Study of the 2017 Heat Wave.

Heat waves are predicted to increase in frequency and duration in many regions as global temperatures rise. These transient increases in temperature above normal average values will have pronounced impacts upon the photosynthetic and stomatal physiology of plants. During the summer of 2017, much of the Mediterranean experienced a severe heat wave.

Design and characterization of crotamine-functionalized gold nanoparticles.

This paper describes the development of a facile and environmentally friendly strategy for supporting crotamine on gold nanoparticles (GNPs). Our approach was based on the covalent binding interaction between the cell penetrating peptide crotamine, which is a snake venom polypeptide with preference to penetrate dividing cells, and a polyethylene glycol (PEG) ligand, which is a nontoxic, water-soluble and easily obtainable commercial polymer. Crotamine was derivatized with ortho-pyridyldisulfide-polyethyleneglycol-N-hydroxysuccinimide (OPSS-PEG-SVA) cross-linker to produce OPSS-PEG-crotamine as the surface modifier of GNP.

Dissecting the role of isoprene and stress-related hormones (ABA and ethylene) in Populus nigra exposed to unequal root zone water stress.

Isoprene is synthesized through the 2-C-methylerythritol-5-phosphate (MEP) pathway that also produces abscisic acid (ABA). Increases in foliar free ABA concentration during drought induce stomatal closure and may also alter ethylene biosynthesis. We hypothesized a role of isoprene biosynthesis in protecting plants challenged by increasing water deficit, by influencing ABA production and ethylene evolution.

Moderate Drought Stress Induces Increased Foliar Dimethylsulphoniopropionate (DMSP) Concentration and Isoprene Emission in Two Contrasting Ecotypes of .

The function of dimethylsulphoniopropionate (DMSP) in plants is unclear. It has been proposed as an antioxidant, osmolyte and overflow for excess energy under stress conditions. The formation of DMSP is part of the methionine (MET) pathway that is involved in plant stress responses.
