Mitochondrial carbonic anhydrase CA VB: Differences in tissue distribution and pattern of evolution from those of CA VA suggest distinct physiological roles

A cDNA for a second mouse mitochondrial carbonic anhydrase (CA) called CA VB was identified by homology to the previously characterized murine CA V, now called CA VA. The full-length cDNA encodes a 317-aa precursor that contains a 33-aa classical mitochondrial leader sequence. Comparison of products expressed from cDNAs for murine CA VB and CA VA in COS cells revealed that both expressed active CAs that localized in mitochondria, and showed comparable activities in crude extracts and in mitochondria isolated from transfected COS cells. Northern blot analyses of total RNAs from mouse tissues and Western blot analyses of mouse tissue homogenates showed differences in tissue-specific expression between CA VB and CA VA. CA VB was readily detected in most tissues, while CA VA expression was limited to liver, skeletal muscle, and kidney. The human orthologue of murine CA VB was recently reported also. Comparison of the CA domain sequence of human CA VB with that reported here shows that the CA domains of CA VB are much more highly conserved between mouse and human (95% identity) than the CA domains of mouse and human CA VAs (78% identity). Analysis of phylogenetic relationships between these and other available human and mouse CA isozyme sequences revealed that mammalian CA VB evolved much more slowly than CA VA, accepting amino acid substitutions at least 4.5 times more slowly since each evolved from its respective human–mouse ancestral gene around 90 million years ago. Both the differences in tissue distribution and the much greater evolutionary constraints on CA VB sequences suggest that CA VB and CA VA have evolved to assume different physiological roles.

A Meta-Analysis of the Effectiveness of Military and Veterans Affairs (VA) Combat-Related PTSD Programs

A meta-analysis was conducted to examine the effectiveness of 55 treatment outcomes reported by military and Veterans Affairs (VA) treatment centers for combat-related posttraumatic stress disorder (PTSD). The analysis includes 46 tested treatment outcomes derived from 21 psychotherapy studies, and nine tested treatment outcomes derived from seven pharmacotherapy studies, which were obtained through PsychINFO and PsychARTICLES database searches, as well as a reference search. Analysis of all treatment outcomes suggested a statistically significant, and meaningful, decrease in PTSD symptoms between baseline and post-treatment time points, t(54) = 9.27, p < .001, d = 0.35. Additionally, analysis of outcomes between psychotherapy and pharmacotherapy treatments resulted in statistically significant differences in PTSD assessment scores at post-test, indicating a greater degree of change for psychotherapy than for pharmacotherapy.

Annotated record of the detailed examination of Mn deposits from the TRANSINDIK R/V Valdivia (VA 07) cruise stations

The studied material was taken from Central Indian Ocean central, during the "TRANSINDIK" campaign of the R/V Valdivia. The campaign was conducted from 14 December 1973 until 23 January 1974, between Beira (Mozambique) and Singapore via Port Louis (Mauritius). The samples were taken on 14 stations aligned on a profile trending West, following approximately the 15th parallel (south). This profile cuts through the Mascarene plateau Basin. The preliminary study presented in this report was carried out as part of a study into the genesis and diagenesis the ocean deposits of the central and southern areas of the Indian Ocean (Laboratoire de GÈologie du MusÈum d'Histoire Naturelle - R.C.P. 212) and under the CNEXO No. 74/1017 contract. The data collected supplements the results of the OSIRIS campaign (R/V Marion Dufresne - TAAF) concerning relations existing between morphostructure and sedimentation and, more particularly, the nature and age of metalliferous deposits associated with Mn concretions.
