Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina (open access)

Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina

This article explores swimming stamina in fish. Mature adult zebrafish (Danio rerio) were subjected to a swimming performance test and then bred within performance groups to discover if enhanced swimming stamina in offspring appears only in juveniles/adults, or if these traits appear as early as larvae.

A novel benzimidazole derivative, MBIC inhibits tumor growth and promotes apoptosis via activation of ROS-dependent JNK signaling pathway in hepatocellular carcinoma (open access)

A novel benzimidazole derivative, MBIC inhibits tumor growth and promotes apoptosis via activation of ROS-dependent JNK signaling pathway in hepatocellular carcinoma

This study further explores a prior screening program carried out using MTT assay that identified a series of novel benzimidazole derivatives, among which Methyl 2-(5-fluoro-2-hydroxyphenyl)-1H-benzo[d]imidazole-5-carboxylate (MBIC) showed highest anticancer efficacy compared to that of chemotherapeutic agent, cisplatin. In this article, the authors find that MBIC inhibited cell viability in different hepatocellular carcinoma (HCC) cell lines without exerting significant cytotoxic effects on normal liver cells. The results of this study demonstrate that MBIC may inhibit cell proliferation via ROS-mediated activation of the JNK signaling cascade in HCC cells.

Badly approximable points on self-affine sponges and the lower Assouad dimension (open access)

Badly approximable points on self-affine sponges and the lower Assouad dimension

This article highlights a connection between Diophantine approximation and the lower Assouad dimension by using information about the latter to show that the Hausdorff dimension of the set of badly approximable points that lie in certain non-conformal fractals, known as self-affine sponges, is bounded below by the dynamical dimension of these fractals. The results, which are the first to advance beyond the conformal setting, encompass both the case of Sierpiński sponges/carpets (also known as Bedford–McMullen sponges/carpets) and the case of Barański carpets.
