Unveiling Interactions between Self-Assembling Peptides and Neuronal Membranes.

The use of self-assembling peptide hydrogels in the treatment of spinal cord and brain injuries, especially when combined with adult neural stem cells, has shown great potential. To advance tissue engineering, it is essential to understand the effect of mechanochemical signaling on cellular differentiation. The elucidation of the molecular interactions at the level of the neuronal membrane still represents a promising area of investigation for many drug delivery and tissue engineering applications.

Land use effects on soil microbiome composition and traits with consequences for soil carbon cycling.

The soil microbiome determines the fate of plant-fixed carbon. The shifts in soil properties caused by land use change leads to modifications in microbiome function, resulting in either loss or gain of soil organic carbon (SOC). Soil pH is the primary factor regulating microbiome characteristics leading to distinct pathways of microbial carbon cycling, but the underlying mechanisms remain understudied.

Bacterial population-level trade-offs between drought tolerance and resource acquisition traits impact decomposition.

Microbes drive fundamental ecosystem processes, such as decomposition. Environmental stressors are known to affect microbes, their fitness, and the ecosystem functions that they perform; yet, understanding the causal mechanisms behind this influence has been difficult. We used leaf litter on soil surface as a model in situ system to assess changes in bacterial genomic traits and decomposition rates for 18 months with drought as a stressor.

Intraoperative Reverse Takotsubo Cardiomyopathy in Liver Transplantation: An Anesthesiologist's Nightmare.

Background: Reverse Takotsubo cardiomyopathy (TTC) is a rare variant of stress cardiomyopathy, characterized by basal akinesia with apical sparing. To our knowledge, this case is the first reported in the literature of intraoperative reverse TTC (rTTC) in liver transplantation.

Case: After a thorough workup, a 19-year-old man, diagnosed with extrahepatic biliary atresia, was taken up for living-related donor liver transplantation.

Opportunities and challenges for microbiomics in ecosystem restoration.

Microbiomics is the science of characterizing microbial community structure, function, and dynamics. It has great potential to advance our understanding of plant-soil-microbe processes and interaction networks which can be applied to improve ecosystem restoration. However, microbiomics may be perceived as complex and the technology is not accessible to all.

Morphoscanner2.0: A new python module for analysis of molecular dynamics simulations.

Molecular dynamics simulations, at different scales, have been exploited for investigating complex mechanisms ruling biologically inspired systems. Nonetheless, with recent advances and unprecedented achievements, the analysis of molecular dynamics simulations requires customized workflows. In 2018, we developed Morphoscanner to retrieve structural relations within self-assembling peptide systems.

studies disclose the underlying link between binding affinity and redox potential in laccase isoforms.

Laccases are copper-containing enzymes belonging to the family of multicopper oxidases (MCOs). All MCOs use molecular oxygen to oxidize a wide range of organic compounds by radical catalysis. One of the key fundamental properties of laccases is having high or low redox potentials depending on the active site organization.

Optimal management of perioperative analgesia regarding immediate and short-term outcomes after liver transplantation - A systematic review, meta-analysis and expert panel recommendations.

Background: Adequate pain control is essential for patients undergoing liver transplantation (LT). Multiple analgesic strategies have been implemented during the perioperative period. There is no consensus on the optimal perioperative analgesia management.

screening of phytochemical compounds and FDA drugs as potential inhibitors for NSP16/10 5' methyl transferase activity.

The recent global pandemic associated with the highly contagious novel coronavirus (SARS-CoV-2) has led to an unpredictable loss of life and economy worldwide, and the discovery of antiviral drugs is an urgent necessity. For the discovery of new drug leads and for the treatment of various diseases, natural products and purified photochemical from medicinal plants are used. The RNA cap was methylated by two S-adenosyl-L-methionine (SAM)-dependent methyltransferases of SARS coronavirus (SARS-CoV-2), catalyzed by NSP16 2'-O-Mtase.

Knowledge hiding in organizational crisis: The moderating role of leadership.

The COVID-19 pandemic has caused organizational crises leading to shutdowns, mergers, downsizing or restructuring to minimize survival costs. In such organizational crises, employees tend to experience a loss or lack of resources, and they are more likely to engage in knowledge hiding to maintain their resources and competitive advantage. Knowledge hiding has often caused significant adverse consequences, and the research on knowledge hiding is limited.

A Comparison of Reproductive Hormones and Biochemical Parameters in Hypothyroid and Euthyroid Postmenopausal Women.

Background: Menopause and hypothyroidism, both individually, affect the reproductive hormone profile as well as body metabolism which is reflected in the form of a deranged biochemical profile. It will be interesting to observe the effects on both these profiles, when menopause is associated with hypothyroidism.

Methods: This study was conducted on 30 postmenopausal women with newly diagnosed primary hypothyroidism and 30 euthyroid menopausal females as controls.

Drought and plant litter chemistry alter microbial gene expression and metabolite production.

Drought represents a significant stress to microorganisms and is known to reduce microbial activity and organic matter decomposition in Mediterranean ecosystems. However, we lack a detailed understanding of the drought stress response of microbial decomposers. Here we present metatranscriptomic and metabolomic data on the physiological response of in situ microbial communities on plant litter to long-term drought in Californian grass and shrub ecosystems.

Liver transplantation and COVID-19 (Coronavirus) infection: guidelines of the liver transplant Society of India (LTSI).

The Liver Transplant Society of India (LTSI) has come up with guidelines for transplant centres across the country to deal with liver transplantation during this evolving pandemic of COVID-19 infection. The guidelines are applicable to both deceased donor as well as living donor liver transplants. In view of the rapidly changing situation of COVID-19 infection in India and worldwide, these guidelines will need to be updated according to the emerging data.

Bio-sensing of organophosphorus pesticides: A review.

Organophosphorus (OP) pesticides have been used widely as agricultural and household pest control agents for almost five decades and persist in our water resources, fruits, vegetables and processed food as health and environmental hazardous compounds. Thus, detection of these harmful OP pesticides at an ease with high sensitivity and selectivity is the need of hour. Bio-sensing technology meet these requirements and has been employed at a large scale for detection.

Land use driven change in soil pH affects microbial carbon cycling processes.

Soil microorganisms act as gatekeepers for soil-atmosphere carbon exchange by balancing the accumulation and release of soil organic matter. However, poor understanding of the mechanisms responsible hinders the development of effective land management strategies to enhance soil carbon storage. Here we empirically test the link between microbial ecophysiological traits and topsoil carbon content across geographically distributed soils and land use contrasts.

Bacterial Physiological Adaptations to Contrasting Edaphic Conditions Identified Using Landscape Scale Metagenomics.

Environmental factors relating to soil pH are important regulators of bacterial taxonomic biodiversity, yet it remains unclear if such drivers affect community functional potential. To address this, we applied whole-genome metagenomics to eight geographically distributed soils at opposing ends of a landscape soil pH gradient (where "low-pH" is ~pH 4.3 and "high-pH" is ~pH 8.

Soil Fungal:Bacterial Ratios Are Linked to Altered Carbon Cycling.

Despite several lines of observational evidence, there is a lack of consensus on whether higher fungal:bacterial (F:B) ratios directly cause higher soil carbon (C) storage. We employed RNA sequencing, protein profiling and isotope tracer techniques to evaluate whether differing F:B ratios are associated with differences in C storage. A mesocosm (13)C labeled foliar litter decomposition experiment was performed in two soils that were similar in their physico-chemical properties but differed in microbial community structure, specifically their F:B ratio (determined by PLFA analyses, RNA sequencing and protein profiling; all three corroborating each other).

Balancing cognitive diversity and mutual understanding in multidisciplinary teams.

Background: Interprofessional health care teams are increasingly utilized in health care organizations. Although there is support for their capacity to solve complex problems, there is also evidence that such teams are not always successful. In an effort to understand the capacity of interprofessional teams to innovate successfully, we investigate the role of cognitive diversity to establish whether and how knowledge differences lead to innovation.
