Evolutionary ecology of opsin gene sequence, expression and repertoire.

Linking molecular evolution to biological function is a long-standing challenge in evolutionary biology. Some of the best examples of this involve opsins, the genes that encode the molecular basis of light reception. In this issue of Molecular Ecology, three studies examine opsin gene sequence, expression and repertoire to determine how natural selection has shaped the visual system. First, Escobar-Camacho et al. () use opsin repertoire and expression in three Amazonian cichlid species to show that a shift in sensitivity towards longer wavelengths is coincident with the long-wavelength-dominated Amazon basin. Second, Stieb et al. () explore opsin sequence and expression in reef-dwelling damselfish and find that UV- and long-wavelength vision are both important, but likely for different ecological functions. Lastly, Suvorov et al. () study an expansive opsin repertoire in the insect order Odonata and find evidence that copy number expansion is consistent with the permanent heterozygote model of gene duplication. Together these studies emphasize the utility of opsin genes for studying both the local adaptation of sensory systems and, more generally, gene family evolution

Species identification of a suspected bone found in blood sausage

The case of an identification for a small bone found in a blood sausage is described. The similitude with a rodent bone leads the consumer to demand the government organism responsible of food quality control. Bone and blood sausage DNA analysis was performed in order to determinate the origin species and the possibility of food contamination and/or adulteration. DNA sequence analysis confirmed the pig origin of both samples with an identity higher than 98%.Fil: Posik, Diego Manuel. Consejo Nacional de Investigaciones Científicas y Técnicas.

Francis F. Maury, M.D. (1840 to 1879): an often forgotten pioneer in early American surgery.

Francis F. Maury (Fig. 1) was born on August 9, 1840, in Danville, Kentucky, where he was raised on a farm by his mother and father. His father was an Episcopal clergyman of Huguenot descent, whose forefathers had fled from France to escape religious persecution. After receiving a Bachelor of Arts degree from Center College in the summer of 1860, he entered medical school at the University of Virginia. After one full term, he matriculated to Philadelphia’s Jefferson Medical College and completed his medical education as a private student under the direction of Dr. Samuel D. Gross.1, 2 He obtained his Doctorate of Medicine in March of 1862 at the age of only 21 years. Such were his talents as a medical student that he was appointed resident physician at the Philadelphia Hospital one month before his graduation. Although he spent only one year there, he developed a reputation as a tireless, devoted, and charming surgeon. In April 1863, Maury was assigned to duty at the South Street General Hospital to serve as acting assistant surgeon in the U.S. Army for two years. In October 1863, he was appointed assistant professor to Dr. Gross and six months later became chief of Dr. Gross’ surgical clinic at Jefferson Medical College. In November 1865, at the age of only 25 years, he returned to the Philadelphia Hospital, where he was appointed one of the chief surgeons on the retirement of Dr. Gross from that institution. In April of 1866, Maury founded the Summer Course on Venereal and Cutaneous Diseases in the Jefferson Medical College, where he taught until his death.1 Although Maury did not consider himself a dermatologist, his expertise in this emerging field was widely recognized

Rapport présenté à la Commission internationale de standardisation du matériel sanitaire, sur les expériences faites dans l'armée suisse avec le Vioforme et les objects de pansement au Vioforme. Etudes sur la durabilité et les méthodes d'appréciation du matériel de pansement au Vioforme

En 1888 existaient déjà, dans le matériel sanitaire de l'armée suisse, des cartouches de pansement avec compresses antiseptiques pour les premiers soins aux blessures. Le principal antiseptique alors en usage, en même temps que l'acide borique et le phénol, était le Iodoforme, employé dès 1881 en chirurgie par Mosetig. Les compresses étaient en gaze iodoformée à 10 %. C'est surtout à l'influence de Kocher que l'on doit, dès lors, l'emploi dans l'armée suisse des compresses antiseptiques pour le premier pansement des plaies. A son point de vue, le matériel venant en contact avec les blessures doit avoir une action désinfectante prolongée; sinon le pansement, bientôt imprégné par le sang et le liquide sécrété par la plaie, devient un véritable milieu de culture pour les microorganismes. Conrad Brunner s'est prononcé dans le même sens, et a démontré par de nombreuses recherches que l'infection des plaies pouvait être enrayée d'une manière efficace grâce aux antiseptiques en poudre.

Graduate Recital, Cello

My M.M. thesis demonstrates a variety of performance literature on the cello, ranging historically from Baroque to Contemporary. The first half of the recital explores the versatility of the cello as a solo instrument, beginning with J. S. Bach\u27s Suite No. 6 in D Major for unaccompanied cello, BWV 1012. I end the first half with a contrasting solo piece that I composed in memory of a recently departed family member. The second half of the recital focuses on the cello as a collaborative instrument with the Kodaly Duo for violin and cello, op. 7
