Inequalities in access to health care: an exploration of the cascade of care for in-transit migrants and asylum seekers, and the general population in Mexico.

Background: All over the world, migrants experience inequalities in access to health care. While this issue has been amply explored among immigrants and refugees in high-income countries, there is a dart of information on the situation of in-transit migrants and asylum seekers (IMAS) in low- or middle-income countries. Since these are the main recipient countries for this population, it is important to document inequalities in access to care in this context, especially for countries such as Mexico, in which IMAS are entitled to health care in par with the general population.

Selective social tolerance drives differentiated relationships among wild female chimpanzees.

Strong, affiliative bonds often function to facilitate social competition through cooperative defence of resources, but the benefits of social bonds may be low when direct competition is less intense or less beneficial. In such cases, one possible outcome is that relationships are weak and undifferentiated. Alternatively, negotiating stable, selectively tolerant relationships may be a strategy to mitigate the costs and risks of sharing space when direct competition is undesirable.

Friends and foes: symbiotic and algicidal bacterial influence on blooms.

Harmful Algal Blooms (HABs) of the toxigenic dinoflagellate (KB) are pivotal in structuring the ecosystem of the Gulf of Mexico (GoM), decimating coastal ecology, local economies, and human health. Bacterial communities associated with toxigenic phytoplankton species play an important role in influencing toxin production in the laboratory, supplying essential factors to phytoplankton and even killing blooming species. However, our knowledge of the prevalence of these mechanisms during HAB events is limited, especially for KB blooms.

Fusion of polymer-coated liposomes and centrifugally spun microfibers as hybrid materials to enhance sustained release.

Liposomes are employed for the delivery of molecular cargo in several classes of systems. For instance, the embedding of loaded liposomes in polymeric fibrous scaffolds has enabled the creation of hybrid materials that mimic biological membranes. Liposomes with unmodified surfaces have been predominantly integrated into fibers, which leads to instabilities due to interfacial incompatibility.

Tailoring Nickel Oxide Thin Films: Comparative Study of Oxidizing Agents in Thermal and Plasma-Enhanced Atomic Layer Deposition.

Thermal atomic layer deposition (TALD) and plasma atomic layer deposition (PALD) were used for producing thin NiO films from nickel(II) acetylacetonate Ni(acac), employing different oxidizing agents (deionized water HO, ozone O, and molecular oxygen O). The films were deposited at 300 °C (TALD) and 220 °C (PALD) over glass substrates; their physical and chemical properties were considerably influenced by the choice of oxidizing agents. In particular, ALD(HO) samples had a low growth per cycle (GPC) and a high concentration of defects.

Effects of Mixed Metal Oxide Catalysts on the Synthesis of Cyclic Carbonates from Epoxides under Atmospheric CO Pressure.

One use of CO as a starting material in organic transformations is in the synthesis of cyclic carbonates and polycarbonates. Due to the low reactivity of CO, this transformation must be carried out in the presence of an efficient catalyst. Although several catalytic systems have been developed in the past decade, reducing the CO pressure at which the reaction is carried out remains one of the main challenges of the process.
