Plus and minus single-stranded DNA separately encapsidated in adeno-associated satellite virions.
Based on physical and chemical determinations, the mnolecular weight of the type 4 adeno-satellite virus is 5.4 X 10(6) daltons, and the virion contains 1.4 X 10(6) daltons of DNA. Denaturation and renaturation studies indicate that the viral genome is a single-stranded DNA molecule and that each virion contains either a minus or a plus strand. Upon extraction, the minus and plus strands unite to form double-stranded DNA molecules with no obvious excess of unpaired strands.

Interference between two adeno-associated satellite viruses: a three-component system.
Adenovirus-associated satellite viruses interfere with the replication of their helper adenoviruses. According to a previous report, this interference is not mediated by interferon. A three-component system comprising simian adenovirus SV15 and satellites types 1 and 4 was studied to determine whether satellite viruses also interfere with one another. Satellite type 1 interfered with the replication of type 4 and vice versa. The degree of interference was directly proportional to the dose of interfering satellite. The events leading to mutual satellite interference were operative during the first 12 hr of replication, the period associated with active synthesis of viral deoxyribonucleic acid.

A cloverleaf skull syndrome probably of Beare-Stevenson type associated with Chiari malformation.
A case of cloverleaf skull (CLS) syndrome with Chiari malformation was reported. The patient developed congenital hydrocephalus, upper airway obstruction and breath holding spells. Ventriculo-peritoneal shunt improved the hydrocephalus, but the patient progressively developed apneic episodes in spite of intubation. Brain magnetic resonance imaging (MRI) disclosed severe Chiari malformation. Laminectomy of the cervical vertebrae and craniectomy at the occipital bone were performed to relieve the brain stem compression. Postoperatively, the respiratory symptoms improved slightly, but 8 weeks later the patient suddenly died. Literature survey revealed that this is the second case report of CLS associated with Chiari malformation. It was assumed that the respiratory problems in our patient are ascribable to the Chiari malformation as well as the upper airway obstruction. The patient here reported seems to be a case of Beare-Stevenson cutis gyrata syndrome, in view of an association of multiple characteristic dysmorphic features, in addition to CLS.
