2 homologs in other crops can offer promising leads to develop plant with better root biomass and architecture and improved agronomics traits, like better water and mineral absorption, salinity and drought tolerance potential.The K+, Na+/H+ antiporter LeNHX2 and the regulatory kinase SlSOS2 are important determinants of salt tolerance in tomato plants and their fruit production ability. In this work, we have analyzed the effects of LeNHX2 and SlSOS2 co-overexpression on fruit production, quality in tomato plants (Solanum lycopersicum L. cv. MicroTom), and analyzed physiological parameters related to salt tolerance. Plants overexpressing LeNHX2, SlSOS2 or both were grown in greenhouse. They were treated with 125 mM NaCl or left untreated and their salt tolerance was analyzed in terms of plant biomass and fruit yield. Under NaCl cultivation conditions, transgenic tomato plants overexpressing either SlSOS2 or LeNHX2 or both grew better and showed a higher biomass compared to their wild-type plants. Proline, glucose and protein content in leaves as well as pH and total soluble solid (TSS) in fruits were analyzed. Our results indicate that salinity tolerance of transgenic lines is associated with an increased proline, glucose and protein content in leaves of plants grown either with or without NaCl. Salt treatment significantly reduced yield, pH and TSS in fruits of WT plants but increased yield, pH and TSS in fruits of transgenic plants, especially those overexpressing both LeNHX2 and SlSOS2. All these results indicate that the co-overexpression of LeNHX2 and SlSOS2 improve yield and fruit quality of tomato grown under saline conditions.The natural capacity of plants to endure salt stress is largely regulated by multifaceted structural and physio-biochemical modulations. Salt toxicity endurance mechanism of six ecotypes of Typha domingensis Pers. was evaluated by analyzing photosynthesis, ionic homeostasis, and stomatal physiology under different levels of salinity (0, 100, 200 and 300 mM NaCl). Typha populations were collected across different areas of Punjab, an eastern province in Pakistan. All studied attributes among ecotypes presented differential changes as compared to control. Different salt treatments not only affected gas exchange attributes but also shown significant modifications in stomatal anatomical changes. As compared to control, net photosynthetic rate, transpiration rate, total chlorophyll contents and carotenoids were increased by 111%, 64%, 103% and 171% respectively, in Sahianwala ecotype among all other ecotypes. see more Similarly, maximum water use efficiency (WUE), sub stomatal CO2 concentration, sodium (Na+) and chloride (Cilable at 10.1007/s12298-021-00963-x.Grime's competition-stress-ruderal (CSR) theory is widely used to study plant species' responses to multiple environmental factors. We compared two models to allocate CSR types the global "StrateFy" model (Pierce et al. Funct Ecol, 31444-457, 2017) and a locally developed morpho-physiological model (Novakovskiy et al. Int J Ecol, p e1323614, 2016). The "StrateFy" model is based on three morphological leaf traits leaf area (LA), leaf dry matter content (LDMC) and specific leaf area (SLA). The morpho-physiological model additionally uses plant height (PH), leaf dry weight (LDW), photosynthetic capacity (PN) and respiration rate (RD), leaf nitrogen, and carbon concentration (LNC, LCC). We applied both models to 74 plant species, the traits of which were measured at mountain (Northern Urals) and plane (Komi Republic, Russia) landscapes of European Northeast. The comparison of the calculated C, S, and R scores showed two groups of species with large and unidirectional differences. The first group consists of specito allocate CSR strategies for a large number of species.

The online version contains supplementary material available at 10.1007/s12298-021-00973-9.Dr. Om Prakash Yadava, CEO and Chief Cardiac Surgeon, National Heart Institute, New Delhi, India, and Editor-in-Chief, Indian Journal of Thoracic and Cardiovascular Surgery, in conversation with Prof. Jai Raman, Professor, Cardiothoracic Surgery at Austin and St. Vincent's Hospitals, Melbourne, Australia, and Oregon Health and Science University, Portland, USA, explore an innovative new concept of supporting and resuscitating the heart on Veno Arterial ECMO before high-risk cardiac surgery in a sick patient.The role of extracorporeal membrane oxygenation (ECMO) is expanding as surgeons look at its utility beyond rescue treatment and have started adopting it for high-risk procedures to provide temporary airway and hemodynamic stabilization. ECMO needs to be deliberated in all patients with mediastinal masses who have compromised airways as well as in those with compression of heart and great vessels. There is a dearth of literature highlighting the definitive role of ECMO in patients with mediastinal masses. This article reviews the available adult literature and highlights the possible situations where the use of ECMO would be supportive in the management of patients with mediastinal masses.

The aim of this review is to discuss the role of extracorporeal membrane oxygenation (ECMO) in cardiogenic shock and its use to bridge patients to heart transplantation.

Consideration of published literature reveals indications for ECMO in cardiogenic shock and tools for patient selection, adequate evidence of its efficacy, its advantages when compared with other temporary mechanical circulatory support devices and details of its use as a bridge to decision, bridge to recovery, bridge to bridge (durable ventricular assist device) and bridge to heart transplant.

ECMO is invaluable in treating patients with medically refractory profound cardiogenic shock and allows for cardiac recovery or planning for permanent heart replacement treatments.

ECMO is invaluable in treating patients with medically refractory profound cardiogenic shock and allows for cardiac recovery or planning for permanent heart replacement treatments.The use of extracorporeal membrane oxygenation (ECMO) is expanding rapidly, and as more centres streamline their management policies, the bioethics literature on ECMO has been highlighting the ethical challenges of using an expensive, resource-intensive technology including its eligibility, duration of support, cost-effectiveness and societal repercussions. The absence of high-quality studies on long-term outcomes of ECMO survivors leads to multiple ethical problems involving patient autonomy, beneficence and clinical wisdom pertaining to its initiation, maintenance and termination. This article reviews some of the ethical challenges that affect decision-making during ECMO therapy and suggests an ethical framework that may help the treating team deal with such conundrums, when the patient does not recover despite being on ECMO.
