Macrophages derived from monocyte precursors undergo specific polarization processes which are influenced by the local tissue environment: classically-activated (M1) macrophages, with a pro-inflammatory activity and a role of effector cells in Th1 cellular immune responses, and alternatively-activated (M2) macrophages, with anti-inflammatory functions and involved in immunosuppression and tissue repair. At least three different subsets of M2 macrophages, namely M2a, M2b and M2c, are characterized in the literature based on their eliciting signals.

We propose a stochastic model in evolutionary game theory where individuals (or subpopulations) can mutate changing their strategies randomly (but rarely) and explore the external environment. This environment affects the selective pressure by modifying the payoff arising from the interactions between strategies. We derive a Fokker-Planck integro-differential equation and provide Monte Carlo simulations for the Hawks vs Doves game. In particular we show that, in some cases, taking into account the external environment favors the persistence of the low-fitness strategy.

Integral estimates for weak solutions to a class of Dirichlet problems for nonlinear, fully anisotropic, elliptic equations with a zero order term are obtained by symmetrization techniques. The anisotropy of the principal part of the operator is governed by a general n-dimensional Young function of the gradient which is not necessarily of polynomial type and need not satisfy the $\Delta_2$-condition.

We are concerned with a priori estimates, in rearrangement form, for weak solutions to fully anisotropic, nonlinear elliptic equations with lower-order terms whose prototype is \begin{equation*} \left\{ \begin{array} [c]{lll} -\hbox{\rm div} \; (a(x, u, \nabla u)) + b(u)=f(x) & \qquad\hbox{\rm in\ } \Omega \\ u=0 & \qquad\text{on}\;\partial\Omega. \end{array} \right. \end{equation*} Here, $\Omega$ is an open bounded set in $\mathbb{R}^{N}$, with $N\geq2$, $a(x, \eta, \xi)$ is a Carath\'{e}odory function fulfilling \begin{equation*} a(x,\eta,\xi)\cdot\xi\geq\Phi\left( \xi\right) \qq

Purpose: We studied microRNAs as potential biomarkers for Pompe disease. Methods: We analyzed microRNA expression by small RNA-seq in tissues from the disease murine model at two different ages (3 and 9 months), and in plasma from Pompe patients. Results: In the mouse model we found 211 microRNAs that were differentially expressed in gastrocnemii and 66 in heart, with a different pattern of expression at different ages. In a preliminary analysis in plasma from six patients 55 microRNAs were differentially expressed.

Background & Aims: Acute liver failure is a rapidly progressive deterioration of hepatic function resulting in high mortality and morbidity. Metabolic enzymes can translocate to the nucleus to regulate histone acetylation and gene expression. Methods: Levels and activities of pyruvate dehydrogenase complex (PDHC) and lactate dehydrogenase (LDH) were evaluated in nuclear fractions of livers of mice exposed to various hepatotoxins including CD95-antibody, ?-amanitin, and acetaminophen.

E-commerce is a sector in continual growth in all countries and, in particular, the increase in B2C (Business to Consumer) e-commerce market has important effects on last-mile deliveries in city areas. The delivery of a parcel to a consumer's address involves not only high costs for both couriers (extended car routes) and consumers (high prices) and also greater environmental pollution. The growing demand for deliveries in urban areas involves increases in traffic and congestion problems and, consequently, environmental issues.

During the seismic cycle, in nature and as well as in lab samples, the crack density of rocks varies substantially, as stressed rocks approach a critical state and eventually fail (Vasseur et al, 2017; Nur, 1972; Gupta, 1973) . At Earth scales, small periodical stress variations such as seasonal loading/unloading and tides (Johnson_etal_2017) are constantly being superimposed on the tectonic loading stress of crustal rocks, inducing periodic changes in crack porosity, pore-fluid pressure, and saturation, that should leave a signature on crustal attenuation.
