Crystal growth and characterization of MgB2: Relation between structure and superconducting properties [PDF]
, 2002 We discuss the important aspects of synthesis and crystal growth of MgB2 under high pressure (P) and temperature (T) in Mg-B-N system, including the optimisation of P-T conditions for reproducible crystal growth, the role of liquid phases in this process, the temperature dependence of crystal size and the effect of growing instabilities on single ...

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins
FEBS Open Bio, EarlyView.With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

FEBS Open Bio, EarlyView.Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.

MicroRNA regulatory mechanisms on Citrus sinensis leaves to magnesium-deficiency
Frontiers in Plant Science, 2016 Magnesium (Mg)-deficiency, which affects crop productivity and quality, widespreadly exists in many agricultural crops, including citrus. However, very limited data are available on Mg-deficiency-responsive microRNAs (miRNAs) in higher plants.

The impact of magnesium deficiency on photosynthesis and photoprotection in Spinacia oleracea
Plant Stress, 2021 Limited magnesium (Mg) supply adversely affects photosynthesis. This is particularly related to the high demand for Mg of key enzymes in the chloroplast, such as the photosystems, the ATP synthase and ribulose-1,5-bisphosphate carboxylase/oxygenase ...

PND-Net: Plant Nutrition Deficiency and Disease Classification using Graph Convolutional Network [PDF]
Scientific Reports, Nature Portfolio, 2024Crop yield production could be enhanced for agricultural growth if various plant nutrition deficiencies, and diseases are identified and detected at early stages. The deep learning methods have proven its superior performances in the automated detection of plant diseases and nutrition deficiencies from visual symptoms in leaves. This article proposes a

Relationship of cognitive decline with glucocerebrosidase activity and amyloid‐beta 42 in DLB and PD
Annals of Clinical and Translational Neurology, EarlyView.Abstract Objective Dementia with Lewy bodies (DLB) and Parkinson's disease (PD) share clinical, pathological, and genetic risk factors, including GBA1 and APOEε4 mutations. Biomarkers associated with the pathways of these mutations, such as glucocerebrosidase enzyme (GCase) activity and amyloid‐beta 42 (Aβ42) levels, may hold potential as predictive ...
