Erythrocyte potassium polymorphism in 14 Spanish goat breeds

Summary. The existence of polymorphism for erythrocyte potassium (Ke) is confirmed in certain Spanish breeds of goat. A statistical boundary is established between two caprine populations: low (LK) and high (HK) red cell potassium, the dividing line being set at 45 m-equiv/l of Ke. Both types are shown to be controlled genetically by an autosomal locus with two alleles K ^L and K ^h, being K ^L dominant over K ^h. The gene frequencies of K ^L and K ^h are determined in 14 native Spanish breeds of goat.     

Genetic relationships between seven Spanish native breeds of cattle

Summary. Ten genetic markers were studied in seven Spanish native cattle breeds, using a total of 725 animals. Of the ten, two were found to be monomorphic in all seven breeds. The genetic relationships of the seven breeds are estimated by three different genetic-statistical methods (genetic distances, main coordinate analysis and cluster analysis), which indicate three clearly distinct groups of populations: one where the Cárdena Andaluza and Alistana Sanabresa are very closely related, one comprising Sayaguesa, Morucha, Asturiana de los Valles and Asturiana de la Montaña cattle, and a third, genetically distant from the other two, comprising only Blanca Cacereña. The dendrogram drawn from the genetic distances matrix would seem to imply that the seven breeds are descended from different ancestors.     

The prevalence and correlates of DSM-IV disorders in the Iraq Mental Health Survey (IMHS)

Data on the prevalence and correlates of anxiety, mood, behavioral, and substance disorders are presented from a 2007-8 national survey of the Iraq population, the Iraq Mental Health Survey (IMHS). The IMHS was carried out by the Iraq Ministry of Health in collaboration with the Iraq Ministry of Planning and the World Health Organization (WHO) World Mental Health (WMH) Survey Initiative. Interviews were administered to a probability sample of Iraqi household residents by trained lay interviewers. The WHO Composite International Diagnostic interview (CIDI) was used to assess DSM-IV disorders. The response rate was 95.2%. The estimated lifetime prevalence of any disorder was 18.8%. Cohort analysis documented significantly increasing lifetime prevalence of most disorders across generations. This was most pronounced for panic disorder and post-traumatic stress disorder, with lifetime-to-date prevalence 5.4-5.3 times as high at comparable ages in the youngest (ages 18-34) as oldest (ages 65+) cohorts. Anxiety disorders were the most common class of disorders (13.8%) and major depressive disorder (MDD) the most common disorder (7.2%). Twelve-month prevalence of any disorder was 13.6%, with 42.1% of cases classified mild, 36.0% moderate, and 21.9% serious. The disorders most often classified serious were bipolar disorder (76.9%) and substance-related disorders (54.9%). Socio-demographic correlates were generally consistent with international epidemiological surveys, with the two exceptions of no significant gender differences in mood disorders and positive correlations of anxiety and mood disorders with education. Only 2.2% of IMHS respondents reported receiving treatment for emotional problems in the 12 months before interview, including 23.7% of those with serious, 9.2% with moderate, and 5.3% with mild disorders and 0.9% of other respondents. Most healthcare treatment, which was roughly equally distributed between the general medical and specialty sectors, was of low intensity. Further analyses of barriers to seeking treatment are needed to inform government efforts to expand the detection and treatment of mental disorders     

Effects of heptapeptide of the tuftsin group with nootropic components of action and piracetam on formation of escape reaction in normal conditions and in conflict situation

In this work we have compared the effect of Tuftsin Group synthetic heptapeptide (TP-1) and Piracetam on learning of avoidance response and its restoring after disturbance provoked by unexpected changes of previously established cause-effect relations in experimental environment. We have pointed out that both of the drugs improve learning but the dynamics is different, namely: Piracetam causes the greatest improvement on the 1st day, meanwhile the Heptapeptide--on the 4th day. Both of them preclude from disturbing avoidance response and this protective action of peptide is more effective.
