SOX10 commonly stains scar in Mohs sections
Sox10 immunostaining is used for the diagnosis and margin evaluation of melanocytic lesions. Sox10 was initially thought not to stain fibrohistiocytic processes. Consequently, it was believed to reliably distinguish desmoplastic melanoma from scar. However, recent data from formalin sections suggest Sox10 is less specific than previously thought. In this report, we demonstrate that Sox10-stained Mohs sections commonly show strong, fractional staining of scar. When using Sox10 with frozen section immunohistochemistry, Mohs practitioners should recognize the potential of this marker to stain scar to avoid overdiagnosis of desmoplastic melanoma
Sugars as the Optimal Biosynthetic Carbon Substrate of Aqueous Life throughout the Universe
Our previous analysis of the energetics of metabolism showed that both the biosynthesis of amino acids and lipids from sugars, and the fermentation of organic substrates, were energetically driven by electron transfer reactions resulting in carbon redox disproportionation (Weber 1997). Redox disproportionation -- the spontaneous (energetically favorable) direction of carbon group transformation in biosynthesis -- is brought about and driven by the energetically downhill transfer of electron pairs from more oxidized carbon groups (with lower half-cell reduction potentials) to more reduced carbon groups (with higher half-cell reduction potentials). In this report, we compare the redox and kinetic properties of carbon groups in order to evaluate the relative biosynthetic capability of organic substrates, and to identify the optimal biosubstrate. This analysis revealed that sugars (monocarbonyl alditols) are the optimal biosynthetic substrate because they contain the maximum number of biosynthetically useful .high energy electrons/carbon atom , while still containing a single carbonyl group needed to kinetically facilitate their conversion to useful biosynthetic intermediates. This conclusion applies to aqueous life throughout the Universe because it is based on invariant aqueous carbon chemistry -- primarily, the universal reduction potentials of carbon groups
La exploración de las categorizaciones de la tipología de los varones violentos en la pareja: un estudio metodológico
Intimate partner violence (IPV) perpetrators were categorized based on whether they were generally violent (GV) or family only violent (FO) using self-report or arrest records. Classification criteria to assess recidivism in perpetrators of IPV were evaluated herein to determine the incremental validity of using a perpetrator’s criminal history in addition to their self-report information for categorization purposes. The concordance rates for categorizing subtypes of male perpetrators were compared for two methods, namely, self-report versus criminal history data. Categorizations were made based on self-reported history of violence and federal criminal records separately. Between measures consistency was defined as whether or not the self-report categorizations matched federal criminal record categorizations. It was hypothesized that self-report would not be sufficient as the sole method of categorizing male perpetrators, and the use of criminal history data would add to the validity of the categorization system. Self-reports of aggression were higher than criminal records of aggression. Using data sources together may yield the best outcomes for offenders and society. Implications are discussed.Se clasificaron los varones que ejercen violencia en las relaciones de pareja (VP) en función de si eran violentos en general (VG) o solo en el entorno familiar (VF), empleando registros de autoinformes o de arrestos. Se analizaron los criterios de clasificación para evaluar la reincidencia de los infractores de VP con el fin de determinar la validez incremental del uso de los antecedentes penales del infractor, además de la información procedente de su autoinforme para la clasificación. Se compararon los índices de concordancia para categorizar los subtipos de infractores masculinos para dos métodos: los datos procedentes de autoinforme y los de antecedentes penales. La categorización se basó en la historia de violencia autoinformada y en los antecedentes penales por separado. La congruencia entre medidas se definió como la coincidencia o discrepancia de la categorización de autoinforme con la categorización de antecedentes penales. Se planteó la hipótesis de que el autoinforme no bastaba como único método para clasificar a los infractores masculinos y que el uso de datos procedentes de antecedentes penales aumentaba la validez del sistema de categorización. Hubo más autoinformes sobre agresión que antecedentes penales de agresión. El uso conjunto de ambos podría tener mejores resultados, tanto para los delincuentes como para la sociedad. Se discuten las implicaciones de estos resultados.S
