The Involvement of the Psychologist's Family in the Establishment of a Public Image of the Profession.

Psychologists of late have been turning increasing attention to the problem of defining their profession (Amer. Psychologist, 1958, 13, 645-652; 1959, 14, 523-524) and outlining a public image (see record 2005-08103-001). The present writer applauds these efforts from the midst of the semantic battlefield upon which the psychologist's family finds itself when communicating with the public.

Significance of inhalation and perfusion scintigraphy for the diagnosis of pulmonary embolism (author's transl)

Inhalation and perfusion scintigrams, general radiological examination of the thorax and an EKG were done on 43 patients with clinically suspected pulmonary embolism. In 11 cases, the clinical diagnosis could be confirmed on the basis of the scintigraphic examination. In the remaining 32 patients, an embolich event could be excluded by pulmonary scintigram, radiological examination and later the clinical course. A synopsis of clinical observations, X-ray and scintigraphy, therefore, permitted a basically reliable diagnosis of pulmonary embolism; selective pulmonary angiography should be used only in exceptional cases.     

Estimated neutron dose to embryo and foetus during commercial flight

A study has been carried out to assess the radiation exposure from cosmic-ray neutrons to the embryo and foetus of pregnant aircrew and air travellers in consideration of the radiation exposure from cosmic-ray neutrons to the embryo and foetus. A Monte Carlo analysis was performed to determine the equivalent dose from neutrons to the brain and body of an embryo at 8 weeks and to the foetus at the 3, 6 and 9 month periods. Neutron fluence-to-absorbed dose conversion coefficients for the foetal brain and for the entire foetal body (isotropic irradiation geometry) have been determined at the four developmental stages. The equivalent dose rate to the foetus during commercial flights has been further evaluated considering the fluence-to-absorbed dose conversion coefficients, a neutron spectrum measured at an altitude of 11.3 km and an ICRP-92 radiation-weighting factor for neutrons. This study indicates that the foetus can exceed the annual dose limit of 1 mSv for the general public after, for example, 15 round trips on commercial trans-Atlantic flights.     

Native state kinetic stabilization as a strategy to ameliorate protein misfolding diseases: a focus on the transthyretin amyloidoses

Small molecule-mediated protein stabilization inside or outside of the cell is a promising strategy to treat protein misfolding/misassembly diseases. Herein we focus on the transthyretin (TTR) amyloidoses and demonstrate that preferential ligand binding to and stabilization of the native state over the dissociative transition state raises the kinetic barrier of dissociation (rate-limiting for amyloidogenesis), slowing and in many cases preventing TTR amyloid fibril formation. Since T119M-TTR subunit incorporation into tetramers otherwise composed of disease-associated subunits also imparts kinetic stability on the tetramer and ameliorates amyloidosis in humans, it is likely that small molecule-mediated native state kinetic stabilization will also alleviate TTR amyloidoses.     

Vascular injuries associated with dislocation of the knee

Two hundred and forty-five knee dislocations were analyzed including forty-one new cases. The high incidence of injuries to the popliteal artery that accompanies this lesion (32 per cent) was confirmed, and it was re-emphasized that vascular repair must be completed within six or at the most eight hours from the time of injury to avoid amputation. Of the patients not treated within that time period, 86 per cent had an amputation and two-thirds of the remaining 14 per cent had ischemic changes.
