Background: Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial glands and stroma surrounded by dense fibrous tissue. Whereas, normal eutopic endometrium shows scarless tissue repair during menstrual cycles, which suggests that the endometriotic tissues have distinct mechanisms of fibrogenesis. During the development of en...

for a finite field $mathbb{f}_q$, the bivariate skew polynomial ring $mathbb{f}_q[x,y;rho,theta]$ has been used to study codes cite{xh}. in this paper, we give some characterizations of the ring $r[x,y;rho,theta]$, where $r$ is a commutative ring. we investigate 2-d skew $(lambda_1,lambda_2)$-constacyclic codes in the ring $r[x,y;rho,theta]/langle x^l-lambda_1,y^s-lambda_2rangle_{mathit{l}}.$ a...

The objective of research was to determine the relationship between business entrepreneurship and local economic development in farmers provinces Virú Chepén. Methodoly basic, quantitative approach, non-experimental design, comparative causal level. Sample size 70 from province results suggest a high positive correlation (rho=0.770 rho=0.811) significant (p 0.05) dimensions production, sociocul...

Noncentral indefinite quadratic expressions in possibly non- singular normal vectors are represented in terms of the difference of two positive definite quadratic forms and an independently distributed linear combination of standard normal random variables. This result also ap- plies to quadratic forms in singular normal vectors for which no general representation is currently available. The ...

the p75 pan-neurotrophin receptor (p75ntr) plays a pivotal role in linking the immune system with the nervous system. p75ntr is required for the development of several characteristic features of allergic asthma. also p75ntr upregulated by reactive schwann cells after peripheral nerve injury. moreover p75ntr and rhoa play a critical role in the regulation of apoptosis. to determine whether the d...

BACKGROUND The Rho GTPases-Rho, Rac, and Cdc42-regulate the dynamics of F-actin (filamentous actin) and myosin-2 with considerable subcellular precision. Consistent with this ability, active Rho and Cdc42 occupy mutually exclusive zones during single-cell wound repair and asymmetric cytokinesis, suggesting the existence of mechanisms for local crosstalk, but how local Rho GTPase crosstalk is co...
