Krüppel-like factor 6 (KLF6) requires its amino terminal domain to promote villous trophoblast cell fusion.

Introduction: Villous cytotrophoblast (vCTB) cells fuse to generate and maintain the syncytiotrophoblast layer required for placental development and function. Krüppel-like factor 6 (KLF6) is a ubiquitous transcription factor with an N-terminal acidic transactivation domain and a C-terminal zinc finger DNA-binding domain. KLF6 is highly expressed in placenta, and it is required for proper placental development.

Inbreeding in a dioecious plant has sex- and population origin-specific effects on its interactions with pollinators.

We study the effects of inbreeding in a dioecious plant on its interaction with pollinating insects and test whether the magnitude of such effects is shaped by plant individual sex and the evolutionary histories of plant populations. We recorded spatial, scent, colour, and rewarding flower traits as well as pollinator visitation rates in experimentally inbred and outbred, male and female plants from European and North American populations differing in their evolutionary histories. We found that inbreeding specifically impairs spatial flower traits and floral scent.

Extracorporeal CO removal and renal replacement therapy in acute severe respiratory failure in COVID-19 pneumonia: Case report.

The COVID-19 pandemic significates an enormous number of patients with pneumonia that get complicated with severe acute respiratory distress syndrome (ARDS), some of them with refractory hypercapnia and hypoxemia that need mechanical ventilation (MV). Those patients who are not candidate to extracorporeal membrane oxygenation (ECMO), the extracorporeal removal of CO (ECCO R) can allow ultra protective MV to limit the transpulmonary pressures and avoid ventilatory induced lung injury (VILI). We report a first case of prolonged ECCO R support in 38 year male with severe COVID-19 pneumonia refractory to conventional support.

Butterflies visit more frequently, but bees are better pollinators: the importance of mouthpart dimensions in effective pollen removal and deposition.

Pollination studies often use visitation frequency of potential pollinators as an indicator of their importance, but this is only one component and may not reflect actual pollen transfer rates. In this study, we determine the most effective pollinator group of Angadenia berteroi, a tropical perennial subshrub with large yellow flowers that set few fruits. We determined visitation frequency and pollen transfer effectiveness of the four most common groups of visitors (long- and short-tongued bees, and skipper and non-skipper butterflies).

A pillared metal-organic framework incorporated with 1,2,3-triazole moieties exhibiting remarkable enhancement of CO2 uptake.

The replacement of the pillar ligand, 4,4'-bipyridine, in the prototypal pillared MOF, MOF-508, with the custom-designed ligand, 4,4'-(2H-1,2,3-triazole-2,4-diyl)dipyridine, affords a porous metal-triazolate framework, MTAF-3, which demonstrates remarkable enhancement of CO(2) uptake capacity by a factor of ~3 compared to the parent MOF-508.

Porous double-walled metal triazolate framework based upon a bifunctional ligand and a pentanuclear zinc cluster exhibiting selective CO2 uptake.

The self-assembly of a custom-designed bifunctional ligand featuring both 1,2,3-triazolate and carboxylate donor groups with a pentanuclear zinc cluster generated in situ affords a double-walled metal triazolate framework (MTAF) material, MTAF-1 (Zn(5)(μ(3)-O)(2)(C(9)N(3)H(5)O(2))(5)(H(+))(4)(H(2)O)(17)(C(3)H(7)NO)(10)), which exhibits a surface area of 2300 m(2)/g and demonstrates interesting selective CO(2) uptake performances.

[Isolation of environmental mycobacteria from soils of Córdoba city Argentina].

The interest for the research on enviromental mycobacteria has risen over the last decades, in part, due to a significant incidence rate rise. Reports from all over the world address the soil as the major source for human contamination. In Argentina two documents report the prevalence of atypical mycobacteriosis at Córdoba (1997), and the isolation of enviromental mycobacteria from soils of the Province of La Pampa (1999) respectively.
