TL;DR: Brief and efficient programs for using SPSS and SAS to conduct parallel analyses and the MAP test are described.
Abstract: Popular statistical software packages do not have the proper procedures for determining the number of components in factor and principal components analyses. Parallel analysis and Velicer's minimum average partial (MAP) test are validated procedures, recommended widely by statisticians. However, many researchers continue to use alternative, simpler, but flawed procedures, such as the eigenvalues-greater-than-one rule. Use of the proper procedures might be increased if these procedures could be conducted within familiar software environments. This paper describes brief and efficient programs for using SPSS and SAS to conduct parallel analyses and the MAP test.

TL;DR: It is shown that H2S is physiologically generated by cystathionine γ-lyase (CSE) and that genetic deletion of this enzyme in mice markedly reduces H 2S levels in the serum, heart, aorta, and other tissues.
Abstract: Studies of nitric oxide over the past two decades have highlighted the fundamental importance of gaseous signaling molecules in biology and medicine The physiological role of other gases such as carbon monoxide and hydrogen sulfide (H2S) is now receiving increasing attention Here we show that H2S is physiologically generated by cystathionine γ-lyase (CSE) and that genetic deletion of this enzyme in mice markedly reduces H2S levels in the serum, heart, aorta, and other tissues Mutant mice lacking CSE display pronounced hypertension and diminished endothelium-dependent vasorelaxation CSE is physiologically activated by calcium-calmodulin, which is a mechanism for H2S formation in response to vascular activation These findings provide direct evidence that H2S is a physiologic vasodilator and regulator of blood pressure

TL;DR: The first public product of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) is its Conceptual Framework as discussed by the authors, which will underpin all IPBES functions and provide structure and comparability to the syntheses that will produce at different spatial scales, on different themes, and in different regions.

TL;DR: The important life-supporting role of hydrogen sulfide (H(2)S) has evolved from bacteria to plants, invertebrates, vertebrate, vertebrates, and finally to mammals, but over the centuries it had only been known for its toxicity and environmental hazard.
Abstract: The important life-supporting role of hydrogen sulfide (H2S) has evolved from bacteria to plants, invertebrates, vertebrates, and finally to mammals. Over the centuries, however, H2S had only been known for its toxicity and environmental hazard. Physiological importance of H2S has been appreciated for about a decade. It started by the discovery of endogenous H2S production in mammalian cells and gained momentum by typifying this gasotransmitter with a variety of physiological functions. The H2S-catalyzing enzymes are differentially expressed in cardiovascular, neuronal, immune, renal, respiratory, gastrointestinal, reproductive, liver, and endocrine systems and affect the functions of these systems through the production of H2S. The physiological functions of H2S are mediated by different molecular targets, such as different ion channels and signaling proteins. Alternations of H2S metabolism lead to an array of pathological disturbances in the form of hypertension, atherosclerosis, heart failure, diabetes...
