Hugoniot data of plastic foams obtained from laser-driven shocks.

In this paper we present Hugoniot data for plastic foams obtained with laser-driven shocks. Relative equation-of-state data for foams were obtained using Al as a reference material. The diagnostics consisted in the detection of shock breakout from double layer Al/foam targets. The foams [poly(4-methyl-1-pentene) with density 130 > rho > 60 mg/cm3] were produced at the Institute of Laser Engineering of Osaka University. The experiment was performed using the Prague PALS iodine laser working at 0.44 microm wavelength and irradiances up to a few 10(14) W/cm2. Pressures as high as 3.6 Mbar (previously unreached for such low-density materials) where generated in the foams. Samples with four different values of initial density were used, in order to explore a wider region of the phase diagram. Shock acceleration when the shock crosses the Al/foam interface was also measured.

Right aortic arch detected in fetal life.

OBJECTIVE: To evaluate the prenatal distribution, associated conditions and outcome of the different types of right aortic arch (RAA) detected in fetal life. METHODS: This was a retrospective review of all cases of RAA detected prenatally between 1998 and 2005 in two tertiary referral centers. RESULTS: In the study period 71 cases of RAA were detected; 26 (37%) had RAA with aberrant left subclavian artery, 23 (32%) had RAA with mirror-image branching, 20 (28%) had RAA of unknown type and two (3%) had double aortic arch. While 20/26 cases with RAA and aberrant left subclavian artery were isolated findings, all 23 cases with RAA and mirror-image branching were associated with cardiac defects, namely tetralogy of Fallot (43%) or pulmonary atresia with ventricular septal defect (22%). Of the 20 cases with RAA, 19 of unknown type were associated with heterotaxy syndromes and had additional cardiac malformations and ambiguities of the situs. The two cases with DAA were isolated findings. Seven cases in our series (10%) had a microdeletion 22q11 and these were significantly associated with extracardiac malformations. The outcome in our series depended solely on the associated cardiac and extracardiac malformations, with the exception of one infant with isolated DAA, in whom a surgical correction was warranted. CONCLUSIONS: RAA detected in fetal life is associated frequently with other cardiac/non-cardiac malformations, heterotaxy syndromes and microdeletions 22q11. The associated conditions vary depending on the branching type of the brachiocephalic vessels and the presence of extracardiac malformations.

[Congenital hip dysplasia in Ostfold 1990-96].

BACKGROUND: The focus in this paper is on the prevalence, risk factors and treatment of developmental dysplasia of the hip (DDH), before and after introduction of sonographic examination in 1993. MATERIAL AND METHODS: 1,469 (8.2%) infants were followed up because of clinical findings or risk factors (542 with X-ray and 927 with sonographic examination). RESULTS: The overall prevalence of DDH was 1.14%; 0.92% in neonates and 0.22% as late DDH. The prevalence of late DDH ranged from 0.07% to 0.52% (p < 0.01) with peaks in spring and autumn. The following changes occurred when sonography was introduced: Newborn DDH decreased from 1.06 to 0.77% (p < 0.05), late DDH decreased from 0.26 to 0.19% (not significant), and treatment duration decreased from 6.2 months (SD 1.4) to 4.2 months (SD 1.3)(p < 0.01). 56 of 198 infants with clinical findings (28%) were confirmed to have sonographic DDH (p < 0.01). Previous risk factors were confirmed. Mothers of infants with late DDH had higher pre-pregnancy weight, 63 kg (SD 11) vs 58.5 kg (SD 7.8), p < 0.02) and lower weight gain in the last trimester, (4.2 kg (SD 2.2) vs 6.6 kg (SD 2.7; p < 0.001), compared to a reference population. INTERPRETATION: Sonography has reduced treatment rate and duration of DDH.

[A new type of construction of artificial heart valves].

All mechanical valve prosthesis have a moving part that during systole totally or partially obstructs the opening area of the valve. As the result the flow of blood to the left ventricle or to the aorta is restricted. The authors present mechanical valve proSthesis with central opening during diastole and have its function similar to the human valve.

Organ donation from the family of a totally brain-dead donor: professional responsiveness.

Authoritative literature and clinically relevant data related to organ donation from a TBD family member lend support that organ donation is a multifaceted and challenging opportunity. These sources call forth multi-professional responsiveness in clinical practice, education, research, public policy, and ethics as advances in organ procurement and transplantation intensify. In turn, opportunities are rich for professionals to appreciate and to receive in new ways organ donation as a gift on behalf of society.

[Incidence of antibodies against leptospira in the blood of breeding sows].

Within a year, 4438 blood sera of sows coming from 25 farms of the Strakonice district were subjected to serological examination by the reaction of microagglutination lysis (RMAL) with 12 strains of Leptospira. The reaction was positive in 3.22% of all the blood sera. Separate significant titres were demonstrated in the reaction with the Leptospira organisms of four serological groups, including Grippotyphosa, Icterohaemorrhagiae, Hebdomadis and Australis. The reactions with the Leptospira of the Canicola serological group were observed only individually as coagglutination with a simultaneous occurrence of antibodies to Leptospira of the Grippotyphosa serological group. The highest number of reactions 119 (75.8%) was demonstrated in titre 400.
