Cell surface CD11c as a neutrophil aging marker molecule

FEBS Open Bio, EarlyView.
Cell surface CD11chi neutrophils were more aged and had better phagocytic function than CD11c−/lo neutrophils. Transcriptomic analysis of CD11chi neutrophils and CD11c−/lo neutrophils in pediatric population showed that the most difference was seen in infants.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

FEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

The C‐terminal truncated splicing variant of NK1R negatively modulates substance P‐stimulated NK1R signaling

FEBS Open Bio, EarlyView.
The neurokinin 1 receptor exists as full‐length (NK1L) and C‐terminally truncated (NK1S) splice variants. We show that NK1S heterodimerizes with NK1L, impairing Gαq coupling and Ca2+ mobilization while enhancing β‐arrestin1 recruitment. NK1S suppresses substance P‐driven gene expression and cell migration, revealing NK1S as an endogenous biased ...

Rendering plant leaves faithfully

ACM SIGGRAPH 2003 Sketches & Applications, 2003
The light passes through these cells into the spongy layer of the leaf. The elliptical cells, which are interspersed with intercellular air spaces, cause internal scattering of the incident radiation and thereby distribute the light within the leaf. This process is important for an optimal absorption of the light by the leaf’s mesophyll.

From plant physiology to pharmacology: fusicoccin leaves the leaves

Planta, 2018
This review highlights 50 years of research on the fungal diterpene fusicoccin, during which the molecule went from a tool in plant physiology research to a pharmacological agent in treating animal diseases. Fusicoccin is a phytotoxic glycosylated diterpene produced by the fungus Phomopsis amygdali, a pathogen of almond and peach plants.

Plant leaves icephobicity

Journal of Coatings Technology and Research, 2017
Ice adhesion and accumulation are well known to cause serious problems for different structures such as wind turbines, power transmission and distribution systems, and aircraft. Development of coatings that can resist icing can solve many challenges in various areas of industry.

Estimation of plant species by classifying plants and leaves in combination

Journal of Field Robotics, 2017
AbstractInformation on which weed species are present within agricultural fields is a prerequisite when using robots for site‐specific weed management. This study proposes a method of improving robustness in shape‐based classifying of seedlings toward natural shape variations within each plant species.

Fluorescence emission spectra of plant leaves and plant constituents

Radiation and Environmental Biophysics, 1991
The UV-B radiation (e.g. 337 nm) induced blue fluorescence (BF) and red chlorophyll fluorescence spectra (RF) of green leaves from plants with different leaf structure were determined and the possible nature and candidates of the blue fluorescence emission investigated.

Statistical shape models of plant leaves

2013 IEEE International Conference on Image Processing, 2013
The shapes of plant leaves are of great importance to plant biologists and botanists, as they can help in distinguishing plant species, measuring their health, analyzing their growth patterns, and understanding relations between various species. We propose a statistical model that uses the Squared Root Velocity Function representation and a Riemannian ...

Biophotonic in situ sensor for plant leaves

Applied Optics, 2010
Knowledge of the water concentration of plants can be helpful in several environmental and agricultural domains. There are many methods for the determination of water content in plant leaves; however, most of them give a relative moisture level or an analytical measure after a previous calibration procedure. Even for other biochemical compounds such as
