Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Molecular and Electrochemical Impedance Spectroscopic Characterization of the Carbopol Based Bigel and Its Application in Iontophoretic Delivery of Antimicrobials

International Journal of Electrochemical Science, 2014
The current study describes development and characterization of carbopol based bigels for the iontophoretic delivery of antimicrobials. The bigels were prepared by mixing carbopol aquagel and sorbitan monostearate (SMS)-sesame oil based oleogels.

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Integrating satellite radar vegetation indices and environmental descriptors with visible-infrared soil spectroscopy improved organic carbon prediction in soils of semi-arid Brazil

Geoderma
Soil Organic Carbon (SOC) is a paramount soil attribute for climate regulation, soil fertility, and agricultural productivity. The global demand for SOC testing came in response to expanding soil management practices aimed at ensuring soil health.

Determination of Some Soil Properties with Near-infrared Reflectance Spectroscopy

Journal of Agricultural Sciences, 2012
At the modern soil classification system, it is necessary to determine the soil parameters, which cannot be identified in situ, under the laboratory conditions. The obtained data can be validated and interpreted by soil formation hypotheses.
