Abstract (sommario):
Rho-associated kinases (ROCKs), the immediate downstream targets of RhoA, are ubiquitously expressed serine-threonine protein kinases that are involved in diverse cellular functions, including smooth muscle contraction, actin cytoskeleton organization, cell adhesion and motility, and gene expression. Recent studies have shown that ROCKs may play a pivotal role in cardiovascular diseases such as vasospastic angina, ischemic stroke, and heart failure. Indeed, inhibition of ROCKs by statins or other selective inhibitors leads to the upregulation and activation of endothelial nitric oxide synthase

Abstract (sommario):
Cell-to-cell contact mediated by cell adhesion is fundamental to the compaction process that ensures blastocyst quality during embryonic development. In this study, we first showed that Rho-associated coiled-coil protein kinases (ROCK1 and ROCK2) were expressed both in porcine oocytes and IVF preimplantation embryos, playing different roles in oocytes maturation and embryo development. The amount of mRNA encoding ROCK1 and the protein concentration clearly increased between the eight-cell and morula stages, but decreased significantly when blastocysts were formed. Conversely, ROCK2 was more ab

Abstract (sommario):
Abstract RhoBTB1 is an atypical Rho GTPase with two BTB domains in addition to its Rho domain. Although most Rho GTPases regulate actin cytoskeletal dynamics, RhoBTB1 is not known to affect cell shape or motility. We report that RhoBTB1 depletion increases prostate cancer cell invasion and induces elongation in Matrigel, a phenotype similar to that induced by depletion of ROCK1 and ROCK2. We demonstrate that RhoBTB1 associates with ROCK1 and ROCK2 and its association with ROCK1 is via its Rho domain. The Rho domain binds to the coiled-coil region of ROCK1 close to its kinase domain.

Abstract (sommario):
Rho kinases (ROCK1 and ROCK2) function downstream of the small GTPase RhoA to drive actomyosin cytoskeletal remodeling. It has often been believed that ROCK1 and ROCK2 may be functionally redundant, as they share a highly conserved kinase domain. However, in this study, we report differential functional effects for these ROCKs at the epithelial zonula adherens (ZA). Using specific siRNA, we found that ROCK1 depletion disrupted cadherin organization at the ZA, accompanied by loss of F-actin and NMIIA, whereas ROCK2 knockdown had no significant effect. Further, ROCK1, but not ROCK2, was necessar

Abstract (sommario):
Moosebar–Gates sandstones are predominantly litharenites, with some feldspathic litharenites. Both the light- and heavy-mineral suites indicate a mixed source characterized by clastic and carbonate sedimentary rocks, acidic to intermediate plutonic and volcanic igneous rocks, and metamorphic rocks. The sediment sources all fall within a recycled orogenic provenance grouping. Histograms showing stratigraphic variation of mineral content do not indicate any significant progressive unroofing of more deeply buried source rocks.The source area was very extensive regionally and extended well into th

Abstract (sommario):
Abstract Reservoir is the trapped location of hydrocarbons with diverse physical rock properties or high heterogeneity. The characteristics of rock heterogeneity significantly influence the rock’s ability to flow fluids, especially hydrocarbons contained within the reservoir rock. Several methods have been developed to classify the heterogeneity of reservoir rocks, such as the Amaful, Wibowo and Permadi methods, among others. These methods are developed based on experiments using sandstone rocks, although in some studies, they are also frequently employed in categorizing carbonate reservoir ro

Minerals and rocks are important natural resources that are formed over a long period of geological history. Spectroscopy is the basis of the identification and characterisation of rocks and minerals via proximal sensing in the field or remote sensing systems with multi- and hyper-spectral capabilities. However, spectral data is scattered around different institutions worldwide and stored in various formats, resulting in poor data usability and an unnecessary waste of time and information.

Abstract (sommario):
Humanity's relationship with rocks is a long-standing one. Belk (1995, p.2) describes archaeological evidence of early assemblages of rocks found in Cro-Magnon caves that would not be out of place in contemporary rock-collections. Historically, apart from being used as material for tools and buildings. rocks were also used for magical, pharmaceutical and decorative purposes. During the Renaissance and Enlightenment, the practice of collecting rocks became associated with the sense of discovery and the colonial expansion of western European civilization across world, and with advances in mining

However, due to the characteristic limitations of grout, such as poor dispersion and bonding properties prompt the need for alternative grouting technologies in rock engineering. Furthermore, understanding how grout materials seal fractures and react to in-situ stress is currently insufficient. In this work, we explored the potential of epoxy-based material as a grout for fractured sandstone rocks and assessed its potential in modifying the overall rock strength. The epoxy-based
