CHEMICAL COMPOSITION FOR RAINWATER COLLECTIONS IN DIFFERENT REGIONS AT QUNEITRA PROVINCE [PDF]

open access: yesJournal of Agricultural Chemistry and Biotechnology, 2012
Chemical compounds concentrations in rain water collections are derived from two main sources: aerosols blown by wind and carried through rain storms, and organic and inorganic matters dissolved along water courses and in water catchments.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Light penetration into fresh water [PDF]

open access: yesJournal of Experimental Biology, 1933
ABSTRACT Potassium-on-copper vacuum photo-electric cells, in conjunction with a thermionic potentiometer and Unipivot galvanometer, have been found to be satisfactory for measuring sub-aqueous light intensities. Some characteristic results indicate that the light intensity at the limit of sub-aqueous vegetation may be much

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Nutrient inputs in mesocosms of an oligotrophic lake fail to sustain an algal bloom

open access: yesEcosphere
Harmful algal blooms (HABs) rapidly change and threaten aquatic ecosystems. HABs in oligotrophic lakes are becoming more commonly observed, despite the long‐held paradigm that algal blooms cannot happen in low‐nutrient systems.
