Abstract: The western margin of the Caribbean Plate is a typical example where oceanic and continental terranes have amalgamated by subduction, collision, and strike-slip processes. The boundaries between these blocks, as well as their tectonostratigraphic records, are generally covered by younger deposits and dense tropical vegetation, which may hamper reconstructing the accretionary evolution of the convergent margin. In that context, the study of overlap sedimentary assemblages represents an important tool to constrain the accretion timing of terranes. In northern Central America, the geology of the suture zone between the Chortis Block and the exotic Siuna Intraoceanic Arc indicates that the two terranes were assembled together during a Hauterivian arc-continent collision (ca. 134-131 Ma). The exotic origin of the intraoceanic arc is based on the nature of metamorphic blocks within and the kinematics of the Siuna Serpentinite Mélange. The short duration of the collision event is suggested by coeval exhumation of the Siuna Serpentinite Mélange and Chortis-derived coarse sedimentation (El Amparo Formation) along the suture zone, rapidly followed by onset of pelagic sedimentation (Rio Matis Formation). Although the collision appears to have been short-lived and preserved only in the suture zone, post-collisional extension affected intra- to back-arc settings of the Chortis Block and led to the formation of kilometer-thick extensional basins. We envisage that the convergent margin inboard of SW Mexico-represented by the fringing Guerrero Intraoceanic Arc and the Mixteca continental terrane-underwent similar post-collisional extension, whereas the western margin of the proto-Caribbean oceanic realm experienced onset of WSW-dipping subduction beneath the accreted Siuna Intraoceanic Arc.

Abstract: In order to increase its territorial knowledge, as well to increase the quality of decision making in what concerns territorial management, Lousada municipal authority started several efforts in order to create one of the first Portuguese geologic maps at the 1:25000 scale. Not only a simple representation of Lousada's geodiversity was produced, but also geoheritage was pinpointed and characterized. The support disclosed here is currently one of the bases of work of several projects of protection and environmental improvement in progress in Lousada.

Abstract: Assessing population responses to climate‐related environmental change is key to understanding the adaptive potential of the species as a whole. Coralline algae are critical components of marine shallow water ecosystems where they function as important ecosystem engineers. Populations of the calcifying algae Corallina officinalis from the centre (southern UK) and periphery (northern Spain) of the North Atlantic species natural distribution were selected to test for functional differentiation in thermal stress response. Physiological measurements of calcification, photosynthesis, respiration, growth rates, oxygen and calcification evolution curves were performed using closed cell respirometry methods. Species identity was genetically confirmed via DNA barcoding. Through a common garden approach, we identified distinct vulnerability to thermal stress of central and peripheral populations. Southern populations showed a decrease in photosynthetic rate under environmental conditions of central locations and central populations showed a decline in calcification rates under southern conditions. This shows that the two processes of calcification and photosynthesis are not as tightly coupled as previously assumed. How the species as whole will react to future climatic changes will be determined by the interplay of local environmental conditions and these distinct population adaptive traits.

Abstract: Current study was aimed to develop a novel mucoadhesive thiolated cyclodextrin (CD) without ionizable groups and an intact ring backbone for drug delivery. Thiolated β-CD was prepared through bromine substitution of its hydroxyl groups followed by replacement to thiol groups using thiourea. The thiolated β-CD was characterized in vitro via dissolution studies, cytotoxicity studies, mucoadhesion studies on freshly excised porcine intestinal mucosa, and inclusion complex formation with miconazole nitrate. Thiolated β-CDs namely β-CD-SH600 and β-CD-SH1200 displayed 558.66 ± 78 and 1163.45 ± 96 µmol thiol groups per gram of polymer, respectively. Stability constant (Kc) of 190 M-1 confirmed the inclusion complex formation of miconazole nitrate with β-CD-SH. Inclusion complexes of β-CD-SH600 and β-CD-SH1200 resulted in 157 and 257-fold increased solubility of miconazole nitrate, respectively. In addition, more than 80 % of thiol groups were stable even after 6 hours at pH 5. Both β-CD-SH showed on at least 1.3-folds improved solubility in water. In contrast to cationic thiolated cyclodextrins of the first generation, both thiomers showed no significant cytotoxicity. The mucoadhesive properties of the new thiolated CDs were 39.73- and 46.37-fold improved, respectively. These results indicate that β-CD-SH might provide a new favorable tool for delivery of poorly soluble drugs providing a prolonged residence time on mucosal surfaces.
