Hemodynamic Response to Three Types of Urban Spaces before and after Lockdown during the COVID-19 Pandemic.

(1) Background: Prolonged lockdowns with stay-at-home orders have been introduced in many countries since the outbreak of the COVID-19 pandemic. They have caused a drastic change in the everyday lives of people living in urbanized areas, and are considered to contribute to a modified perception of the public space. As research related to the impact of COVID-19 restrictions on mental health and well-being emerges, the associated longitudinal changes of brain hemodynamics in healthy adults remain largely unknown.

[Mild hemophilia A diagnosed at the onset of acute epidural hematoma after lumbar epidural block].

The patient was a 36-year-old man who had been aware of a mild bleeding tendency since childhood, but did not show any history of severe bleeding. After lumbar epidural block was performed for pain caused by lumbar disc herniation, the patient developed paraplegia due to an acute epidural hematoma, and rectovesical disorder. He was admitted to our hospital, and wide fenestration and hematoma evacuation were performed.

Hemophagocytic syndrome associated with severe adenoviral pneumonia: usefulness of real-time polymerase chain reaction for diagnosis.

In infection-associated hemophagocytic syndrome (HPS) the causative pathogen is often undetected, except in cases of herpes virus infections. We describe a 12-year-old girl with life-threatening pneumonia with HPS caused by an adenovirus. She was admitted with complaints of persistent fever and systemic petechiae/purpura.

Genetic characterisation of adenovirus type 8 isolated in Hiroshima city over a 15 year period.

Aims: To investigate the genetic differences among the strains of adenovirus type 8 (Ad8) circulating in Hiroshima city, Japan, and to study their circulation pattern.

Methods: One hundred and twenty nine strains of adenovirus type 8 (Ad8) were isolated in Hiroshima City over a 15 year period (1983-97) from patients with keratoconjunctivitis, and analysed with six restriction enzymes-BamHI, HindIII, PstI, SacI, SalI, and SmaI-to investigate possible relations among the isolates and their genetic variability. Seven hypervariable regions of the hexon gene that carry the type specific epitope were also sequenced to investigate the variation among the genome types.

Characterization of VP4 and VP7 of a murine rotavirus (YR-1) isolated in Japan.

Nucleotide and deduced amino acid sequences of the outer capsid proteins VP4 and VP7 of a murine rotavirus strain (YR-1) isolated in Japan were determined. Comparisons of the VP7 amino acid sequence of YR-1 with other murine rotavirus strains (EB, EW, EC, EL and EHP) (1) showed that YR-1 was highly homologous to EB, EW, EC, EL and EHP. Moreover, YR-1 was more closely related to strains representing G3 than to any other G type.
