The influence of a tomato food matrix on the bioavailability and plasma kinetics of oral gamma-aminobutyric acid (GABA) and its precursor glutamate in healthy men.

Food & Function, 2022
Gamma-aminobutyric acid (GABA) and its precursor glutamate play signaling roles in a range of tissues. Both function as neurotransmitters in the central nervous system, but they also modulate pancreatic and immune functioning, for example.

A Matrix Integral Solution to [P,Q]=P and Matrix Laplace Transforms [PDF]

, 1996
In this paper we solve the following problems: (i) find two differential operators P and Q satisfying [P,Q]=P, where P flows according to the KP hierarchy \partial P/\partial t_n = [(P^{n/p})_+,P], with p := \ord P\ge 2; (ii) find a matrix integral ...

On Complex Gamma-Function Integrals [PDF]

Symmetry, Integrability and Geometry: Methods and Applications, 2019
It was observed recently that relations between matrix elements of certain operators in the ${\rm SL}(2,\mathbb R)$ spin chain models take the form of multidimensional integrals derived by R.A. Gustafson.

Some Relations on the _rR_s(P,Q,z) Matrix Function

Axioms, 2023
In this paper, we derive some classical and fractional properties of the rRs matrix function by using the Hilfer fractional operator. The theory of special matrix functions is the theory of those matrices that correspond to special matrix functions such ...

Expected Values of Scalar-Valued Functions of a Complex Wishart Matrix

Mathematics, 2023
The complex Wishart distribution has ample applications in science and engineering. In this paper, we give explicit expressions for E(tr(Wh))g(tr(Wj))i and E(tr(W−h))g(tr(W−j))i, respectively, for particular values of g, h, i, j, g+h+i+j≤5, where W ...

Gamma-glutamyl carboxylase mutations differentially affect the biological function of vitamin K-dependent proteins.

Blood, 2020
Gamma-glutamyl carboxylase (GGCX) is an integral membrane protein that catalyzes posttranslational carboxylation of a number of vitamin K-dependent (VKD) proteins involved in a wide variety of physiological processes, including blood coagulation ...
