Functional leaf traits indicate phylogenetic signals in forests across an elevational gradient in the central Himalaya.

J Plant Res 2021 Apr 9. Epub 2021 Apr 9.

Global Ecology Unit, CSIC, CREAF-CSIC-UAB, Bellaterra, Catalonia, 08913, Spain.

Traits are the primary attributes that distinguish a species niche. Species and higher taxa are part of a structured phylogeny, and variation in plant traits depends on lineage as well as on environmental conditions. Therefore, it is crucial to investigate linkages between taxonomic identity, shared ancestry, and environment for understanding the variation in leaf traits. Read More

Stem Cell Res Ther 2021 Apr 6;12(1):225. Epub 2021 Apr 6.

National & Local Joint Engineering Research Center of Biodiagnosis and Biotherapy, Precision Medicine Institute, The Second Affiliated Hospital of Xi'an Jiaotong University, No.157 Xiwu Road, Xi'an, 710004, China.

Background: Premature exfoliation of the deciduous teeth is a common manifestation in childhood patients with hypophosphatasia (HPP), which is an autosomal inherited disease caused by ALPL mutations. Dysplasia of the cementum, dentin, and alveolar bone has been proposed to be the main reasons for the exfoliation of teeth, while the extraordinarily complex intracellular mechanisms remain elusive. Dental pulp stem cells (DPSCs) have been demonstrated to successfully regenerate functional pulp-dentin-like tissue. Read More

Exploring a Chemotactic Role for EVs from Progenitor Cell Populations of Human Exfoliated Deciduous Teeth for Promoting Migration of Naïve BMSCs in Bone Repair Process.

Stem Cells Int 2021 17;2021:6681771. Epub 2021 Mar 17.

Department of Oral and Biomedical Sciences, School of Dentistry, College of Biomedical and Life Sciences, Cardiff University, Cardiff, UK.

Mobilization of naïve bone marrow mesenchymal stromal cells (BMSCs) is crucial to desired bone regeneration in both orthopedic and dental contexts. In such conditions, mesenchymal progenitor cell populations from human exfoliated deciduous teeth (SHEDs) present advantageous multipotent properties with easy accessibility which makes them a good candidate in both bone and periodontal tissue regeneration. Extracellular vesicles (EVs) are a functional membranous structure which could participate in multiple cell interactions and imitate the biological functions of their parenting cells largely.

Impact of non-restorative cavity control on proximal carious lesions of anterior primary teeth on the tooth survival and patient-centered outcomes (CEPECO 2): study protocol for a non-inferiority randomized clinical trial.

BMC Oral Health 2021 Mar 31;21(1):167. Epub 2021 Mar 31.

Graduate Program in Dentistry, Ibirapuera University, Av. Interlagos 1329, São Paulo, SP, 04661-100, Brazil.

Background: Studies have questioned the necessity of restoring cavitated carious lesion on primary teeth, once the control of biofilm is the most important factor to arrest these lesions. This randomized clinical trial aimed to compare the survival of teeth treated with a non-restorative cavity control (NRCC) compared to resin composite restorations (RCR) on proximal carious lesion in anterior primary teeth, as well as the impact of these treatments on patient-centered outcomes.

Methods: A randomized clinical trial with two parallels arms (1:1) will be conducted. Read More

Primary tissues may affect estimates of cavitation resistance in ferns.

New Phytol 2021 Mar 31. Epub 2021 Mar 31.

Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA, 95060, USA.

Different methods of measuring cavitation resistance in fern petioles lead to variable results, particularly with respect to the P metric. We hypothesized that the fern dictyostele structure affects air entry into the xylem, and thus impacts the shape of the vulnerability curve. Our study examined this variation by comparing vulnerability curves constructed on petioles collected from evergreen and deciduous ferns in the field, with curves generated using the standard centrifuge, air injection and bench-top dehydration methods.

Increasing shrub damage by invertebrate herbivores in the warming and drying tundra of West Greenland.

Oecologia 2021 Mar 31. Epub 2021 Mar 31.

Ecology, Evolution, Ecosystems and Society Graduate Program, Dartmouth College, Hanover, NH, USA.

Rapid warming is predicted to increase insect herbivory across the tundra biome, yet how this will impact the community and ecosystem dynamics remains poorly understood. Increasing background invertebrate herbivory could impede Arctic greening, by serving as a top-down control on tundra vegetation. Many tundra ecosystems are also susceptible to severe insect herbivory outbreaks which can have lasting effects on vegetation communities. Read More
