To determine the influence of a 17-day exposure to real and simulated spaceflight (SF) on cardiorespiratory function during exercise, four male crewmembers of the STS-78 space shuttle flight and eight male volunteers were studied before, during, and after the 17-day mission and 17 days of -6 degrees head-down-tilt bed rest (BR), respectively. Measurements of oxygen uptake, pulmonary ventilation...

<p>This article presents Michael Sandel’s concept on the tyranny of meritocracy and reimagining solidarity its<br />relevance in Indonesia. Meritocracy is a kind ideology that believes those who are successful deserve to<br />breathe their success to heart’s content, while for fail, there no one blame but themselves.<br />Sandel’s view this logic makes undermines togethe...

The atmospheric budget of methyl bromide (CH(3)Br), an ozone-depleting gas, is highly uncertain, because it has complex sources and sinks. Although oceans, biomass burning, and industrial production are identified as the major sources, the fraction of CH(3)Br that is contributed by each source is not well known. A mass-balance approach that exploits differences in the carbon isotopic signature ...

Brassinosteroids are essential hormones for plant growth and development. Genetic studies have identified key components of the BR signaling pathway, including the cell-surface receptor kinases that perceive BR, an intracellular kinase and a phosphatase, and nuclear transcription factors. Subsequent biochemical studies have revealed many details about signaling events from BR perception at the ...

Bromine is ubiquitously present in animals as ionic bromide (Br(-)) yet has no known essential function. Herein, we demonstrate that Br(-) is a required cofactor for peroxidasin-catalyzed formation of sulfilimine crosslinks, a posttranslational modification essential for tissue development and architecture found within the collagen IV scaffold of basement membranes (BMs). Bromide, converted to ...

In the title compound, [MnBr(C(10)H(9)N(3))(2)(H(2)O)]Br, the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)BrO octa-hedral environment defined by four N atoms of two chelating di-2-pyridyl-amine (dpa) ligands, one Br(-) anion and one O atom of a water ligand. As a result of the different trans effects of Br, N and O atoms, the Mn-N bond trans to the Br atom is slightly long...

In the title compound, C(8)H(12)Br(4), the cyclo-hexane ring exhibits a chair conformation. The C-Br distances range from 1.964 (6) to 1.985 (5) Å and the C-C distances range from 1.496 (6) to 1.543 (7) Å. Short inter-molecular Br⋯Br contacts [3.467 (4) Å] occur in the crystal.

In the title compound, C(14)H(12)Br(2), the Br atoms lie on opposite sides of their ring plane. The biphenyl inter-planar angle is 53.52 (8)°. The packing is characterized by several H⋯Br contacts to each Br atom, but at long distances of 3.07-3.43 Å.

In the pyramidal-shaped mol-ecule of the title compound, C(10)H(12)Br(4), the four terminal Br-C bond distances are nearly identical, ranging from 1.964 (4) to 1.974 (4) Å. The Br⋯Br distance of 3.6553 (7) Å indicates van der Waals contacts between mol-ecules in the crystal structure.
