A Conceptual Model for Detecting Small-Scale Forest Disturbances Based on Ecosystem Morphological Traits

Publication Type: Academic Journal

Source(s): Remote Sensing, Vol 14, Iss 933, p 933 (2022)

Abstract: Current LiDAR-based methods for detecting forest change use a host of statistically selected variables which typically lack a biological link with the characteristics of the ecosystem. Consensus of the literature indicates that many authors use LiDAR t...

The impact of body mass index on adaptive immune cells in the human bone marrow

Publication Type: Academic Journal

Source(s): Immunity & Ageing, Vol 17, Iss 1, Pp 1-11 (2020)

Abstract: Abstract Background Obesity has been associated with chronic inflammation and oxidative stress. Both conditions play a determinant role in the pathogenesis of age-related diseases, such as immunosenescence. Adipose tissue can modulate the function of t...

Basic Steps to Promote Biorefinery Value Chains in Forestry in Italy

Publication Type: Academic Journal

Source(s): Sustainability, Vol 13, Iss 11731, p 11731 (2021)

Abstract: Biorefineries are an important pillar to conduct the transition toward a circular bioeconomy. Forestry value chains produce wood biomass from harvesting and processing residues that have potential to be used in biorefineries, but currently, these resid...

HIV-Specific T Cells Can Be Generated against Non-escaped T Cell Epitopes with a GMP-Compliant Manufacturing Platform

Publication Type: Academic Journal

Source(s): Molecular Therapy: Methods & Clinical Development, Vol 16, Iss , Pp 11-20 (2020)

Abstract: Although anti-retroviral therapy (ART) is successful in suppressing HIV-1 replication, HIV latently infected reservoirs are not eliminated, representing a major hurdle in efforts to eradicate the virus. Current strategies to eradicate HIV involve two s...

Peripheral antibody concentrations are associated with highly differentiated T cells and inflammatory processes in the human bone marrow

Publication Type: Academic Journal

Source(s): Immunity & Ageing, Vol 16, Iss 1, Pp 1-10 (2019)

Abstract: Abstract Background Antigen-experienced immune cells migrate back to the bone marrow (BM), where they are maintained in BM survival niches for an extended period. The composition of T cell subpopulations in the BM changes with age, leading to an accumu...

Post-drought decline of the Amazon carbon sink

Publication Type: Academic Journal

Source(s): Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)

Abstract: Forests of the Amazon Basin have experienced frequent and severe droughts in recent years with significant impacts on their carbon cycling. Here, using satellite LiDAR samples from 2003 to 2008, the authors show the long-term legacy of these droughts w...

Fire Effects on Understory Forest Regeneration in Southern Amazonia

Publication Type: Academic Journal

Source(s): Frontiers in Forests and Global Change, Vol 3 (2020)

Abstract: Fire in tropical forests increases tree mortality, degrades forest structure, and reduces carbon stocks. Currently, there are large gaps in understanding how fire affects understory forest structure and composition, interactions with fire recurrence, a...

Long-term maintenance of diphtheria-specific antibodies after booster vaccination is hampered by latent infection with Cytomegalovirus

Publication Type: Academic Journal

Source(s): Immunity & Ageing, Vol 14, Iss 1, Pp 1-5 (2017)

Abstract: Abstract Many currently used vaccines are less immunogenic in the elderly compared to young adults. The impact of latent infection with Cytomegalovirus (CMV) on vaccine-induced antibody responses has been discussed controversially. We have demonstrated...

Concentric and Eccentric Endurance Exercise Reverse Hallmarks of T-Cell Senescence in Pre-diabetic Subjects

Publication Type: Academic Journal

Source(s): Frontiers in Physiology, Vol 10 (2019)

Abstract: The peripheral T-cell pool undergoes a striking age associated remodeling which is accelerated by progressive insulin resistance. Exercise training is known to delay several aspects of T-cell senescence. The purpose of the current study was to investig...

CD8+HLADR+ Regulatory T Cells Change With Aging: They Increase in Number, but Lose Checkpoint Inhibitory Molecules and Suppressive Function

Publication Type: Academic Journal

Source(s): Frontiers in Immunology, Vol 9 (2018)

Abstract: CD4+ regulatory T cells have been intensively studied during aging, but little is still known about age-related changes of other regulatory T cell subsets. It was, therefore, the goal of the present study to analyze CD8+human leukocyte antigen–antigen ...
