Chronic medical illness : the counselor\u27s role

In the next few decades, the number of chronically medically ill individuals in the United States will increase dramatically. To implement necessary interventions to improve their care, the United States health care system must make changes in the approaches used for these individuals. Counselors can play a critical role in these changes. By incorporating counselors in the care of individuals with chronic medical illnesses, the health care system will be better able to provide interventions that aid in effectively coping with the illnesses and the many psychosocial ramifications of the illnesses

Analysis of rodent remains from the Las Vueltas 1 archaeological site, Tierra del Fuego, Argentina

Diversas especies de roedores se encuentran con frecuencia en los sitios arqueológicos del norte de Tierra del Fuego. Sin embargo, discriminar las vías de incorporación en los contextos arqueofaunísticos y su potencialidad resulta una tarea ardua. La identificación de aquellos restos que ingresaron por acción antrópica o por agentes naturales resulta necesaria para poder inferir el rol que tuvieron en la subsistencia humana. En este trabajo se estudian los restos de roedores del sitio arqueológico Las Vueltas 1 (Isla Grande de Tierra del Fuego, Argentina), donde representan el segundo taxón más abundante en la muestra. Se identificaron un total de 2191 elementos esqueletarios; 1488 corresponden al caviomorfo Ctenomys magellanicus y 703 a representantes de la familia Cricetidae, con al menos 4 especies. La interpretación tafonómica efectuada sugiere un origen múltiple; buena parte del material parece haber ingresado por la acción acumuladora de aves rapaces y cánidos y también por incorporación natural a través de muerte en madrigueras. No obstante y aunque en menor grado, hay evidencias de consumo y descarte antrópico en C. magellanicus.It is frequent to find the remains of several rodent species among the many archaeological sites of Northern Tierra del Fuego. However, the taphonomic interpretation of rodents is a complex issue, given that it is necessary to identify if these were incorporated into the archaeological assemblages through anthropic or natural action or agents. Yet, the identification of those assemblages that accumulated through human action or due to natural agents is an important issue given that only then we can infer the role that rodents had in human subsistence. In this article, we study rodent remains recovered from the archaeological site of Las Vueltas 1 (Isla Grande de Tierra del Fuego, Argentina); here rodents represented the second most common taxon present in the assemblage. A total of 2191 skeletal elements were recorded; 1488 remains belonged to the caviomorph, Ctenomys magellanicus, while 703 specimens belonged to at least four Cricetidae species. From a taphonomic perspective, a large number of the remains would have entered the archaeological assemblage through actions by raptors, carnivores, and as a result of natural death in burrows. Nevertheless, although to a lesser extent, there is also evidence of human consump- tion and discard of C. magellanicus.Fil: Santiago, Fernando Carlos.

Detection of an intergalactic meteor particle with the 6-m telescope

On July 28, 2006 the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences recorded the spectrum of a faint meteor. We confidently identify the lines of FeI and MgI, OI, NI and molecular-nitrogen N_2 bands. The entry velocity of the meteor body into the Earth's atmosphere estimated from radial velocity is equal to 300 km/s. The body was several tens of a millimeter in size, like chondrules in carbon chondrites. The radiant of the meteor trajectory coincides with the sky position of the apex of the motion of the Solar system toward the centroid of the Local Group of galaxies. Observations of faint sporadic meteors with FAVOR TV CCD camera confirmed the radiant at a higher than 96% confidence level. We conclude that this meteor particle is likely to be of extragalactic origin. The following important questions remain open: (1) How metal-rich dust particles came to be in the extragalactic space? (2) Why are the sizes of extragalactic particles larger by two orders of magnitude (and their masses greater by six orders of magnitude) than common interstellar dust grains in our Galaxy? (3) If extragalactic dust surrounds galaxies in the form of dust (or gas-and-dust) aureoles, can such formations now be observed using other observational techniques (IR observations aboard Spitzer satellite, etc.)? (4) If inhomogeneous extragalactic dust medium with the parameters mentioned above actually exists, does it show up in the form of irregularities on the cosmic microwave background (WMAP etc.)?Comment: 9 pages, 6 EPS figure

Estudio comparativo del postoperatorio con utilización de iodoformo

En un grupo de 100 pacientes concurrentes a la Cátedra de Cirugía "A" de la UNLP se practicaron exodoncias complicadas en molares y premolares a 50 pacientes se les incorporo yodoformo y al resto no. Luego de realizar la avulsión de las piezas se llego a la conclusión de que las complicaciones postoperatorias de tipo infecciosas eran nulas en los casos donde se administró yodoformo.Facultad de Odontologí

Ancient genomes in South Patagonia reveal population movements associated with technological shifts and geography

Archaeological research documents major technological shifts among people who have lived in the southern tip of South America (South Patagonia) during the last thirteen millennia, including the development of marine-based economies and changes in tools and raw materials. It has been proposed that movements of people spreading culture and technology propelled some of these shifts, but these hypotheses have not been tested with ancient DNA. Here we report genome-wide data from 20 ancient individuals, and co-analyze it with previously reported data. We reveal that immigration does not explain the appearance of marine adaptations in South Patagonia. We describe partial genetic continuity since ~6600 BP and two later gene flows correlated with technological changes: one between 4700–2000 BP that affected primarily marine-based groups, and a later one impacting all <2000 BP groups. From ~2200–1200 BP, mixture among neighbors resulted in a cline correlated to geographic ordering along the coast.Fil: Nakatsuka, Nathan. Harvard Medical School; Estados UnidosFil: Luisi, Pierre.

Motor Decline in Clinically Presymptomatic Spinocerebellar Ataxia Type 2 Gene Carriers

BACKGROUND: Motor deficits are a critical component of the clinical characteristics of patients with spinocerebellar ataxia type 2. However, there is no current information on the preclinical manifestation of those motor deficits in presymptomatic gene carriers. To further understand and characterize the onset of the clinical manifestation in this disease, we tested presymptomatic spinocerebellar ataxia type 2 gene carriers, and volunteers, in a task that evaluates their motor performance and their motor learning capabilities. METHODS AND FINDINGS: 28 presymptomatic spinocerebellar ataxia type 2 gene carriers and an equal number of control volunteers matched for age and gender participated in the study. Both groups were tested in a prism adaptation task known to be sensible to both motor performance and visuomotor learning deficits. Our results clearly show that although motor learning capabilities are intact, motor performance deficits are present even years before the clinical manifestation of the disease start. CONCLUSIONS: The results show a clear deficit in motor performance that can be detected years before the clinical onset of the disease. This motor performance deficit appears before any motor learning or clinical manifestations of the disease. These observations identify the performance coefficient as an objective and quantitative physiological biomarker that could be useful to assess the efficiency of different therapeutic agents
