Autism spectrum disorder (ASD) is a mental condition, present from early childhood, characterized by great difficulty in communicating and forming relationships with others and using language. In the last four decades many studies have shown that immune responses in different regions of brain play an important role in ASD pathogenicity. A conservative estimate based on the research suggests tha...
We present experimental data providing evidence for the formation of transient ($\sim 20~\mu$s) plasmas that are simultaneously weakly magnetized (i.e., Hall magnetization parameter $\omega \tau > 1$) and dominated by thermal pressure ratio thermal-to-magnetic $\beta 1$). Particle collisional mean free paths an appreciable fraction overall system size. These formed via head-on merging two launc...
We previously identified and characterized a novel tumor growth inhibitor and a fatty acid-binding protein in human mammary gland and named it the mammary-derived growth inhibitor-related gene (MRG). Here, the effects of MRG on mammary gland differentiation and its interaction with omega-3 polyunsaturated fatty acids (omega-3 PUFAs) on growth inhibition were investigated. MRG protein expression...
A new member of the cytochrome P450 (CYP) 4A subfamily (CYP4A21) was recently cloned by PCR from pig liver [Lundell, Hansson, and Wikvall (2001) J. Biol. Chem. 276, 9606-9612]. This enzyme does not catalyse omega- or (omega-1)-hydroxylation of lauric acid, the model substrate for CYP4A enzymes. Instead, CYP4A21 participates in bile acid biosynthesis in the pig. Extensive studies, primarily cond...
Let $ a_0 (omega), a_1 (omega), a_2 (omega), dots, a_n (omega)$ be a sequence of independent random variables defined on a fixed probability space $(Omega, Pr, A)$. There are many known results for the expected number of real zeros of a polynomial $ a_0 (omega) psi_0(x)+ a_1 (omega)psi_1 (x)+, a_2 (omega)psi_2 (x)+...
The aim of this study was to investigate whether the omega-3 fatty acids help to improve erectile function in an atherosclerosis-induced erectile dysfunction rat model. A total of 20 male Sprague-Dawley rats at age 8 weeks were divided into three groups: Control group (n = 6, untreated sham operated rats), Pathologic group (n = 7, untreated rats with chronic pelvic ischemia [CPI]), and Treatmen...
After dissociation of the E. coli recBc DNase (ATP-dependent DNase) with concentrated NaCl, two subunit proteins were isolated by ion exchange chromatography. Combination and subsequent incubation of the subunits resulted in the appearance of the original DNase. The subunit proteins, designated alpha and beta, have s(20,omega) of 4.1 S and 8.1 S, respectively. The alpha subunit possesses neithe...
In the present paper we study a conformally flat generalized Ricci recurrent perfect fluid spacetime with constant scalar as solution of modified $F(R)$-gravity theory. We show that Robertson-Walker is Recurrent if and only it symmetric. The type matter shown to have EoS $\omega=-1$. Some energy conditions are analyzed couple popular toy models $F(R)$-gravity, like $F(R)= R+\alpha R^m $ where $...
Topological electronic transitions from omega- to alpha-phase and alpha- beta-phase that occur with an increase in the concentration of substitution atoms solid solutions titanium iron group metals are considered. It is found due difference potentials Hubbard repulsion atoms, as well temperature Bose excitations, spin charge fluctuations electron density topological alpha phase. Accounting for ...
Molecular evolution has always been a subject of discussions, and researchers are interested in understanding how proteins with similar scaffolds can catalyze different reactions. In the superfamily of serine penicillin-recognizing enzymes, D-alanyl-D-alanine peptidases and beta-lactamases are phylogenetically linked but feature large differences of reactivity towards their respective substrate...
