Purpose We report here a newborn male infant with striking features consistent with severe Pfeiffer syndrome type II, including cloverleaf skull deformity with pansynostosis, extreme proptosis, upper extremity contractures, broad big toes and thumbs with varus deviation and genetic mutation in the FGFR2 gene. The authors review the ophthalmic complications in Pfeiffer syndrome and discuss the u...
Conventional tRNAs have highly conserved sequences, four-armed cloverleaf secondary structures, and L-shaped tertiary structures. However, metazoan mitochondrial tRNAs contain several exceptional structures. Almost all tRNAs(Ser) for AGY/N codons lack the D-arm. Furthermore, in some nematodes, no four-armed cloverleaf-type tRNAs are present: two tRNAs(Ser) without the D-arm and 20 tRNAs without...
The cortical hierarchy of the human visual system has been shown to be organized around retinal spatial coordinates throughout much of low- and mid-level visual processing. These regions contain visual field maps (VFMs) that each follows the organization of the retina, with neighboring aspects of the visual field processed in neighboring cortical locations. On a larger, macrostructural scale, g...
Osteopathia striata with cranial sclerosis (OSCS) is a rare X-linked dominant genetic disorder resulting mutation in the WTX gene. Clinically, OSCS presents with linear striations in the metaphyseal region of the long bones and pelvis in combination with sclerosis of the cranium and face. A twenty-seven year old G5T1P3A0L2 woman with a history of periand neonatal infant male deaths was referred...
On the basis of sequence alignments and secondary structure comparisons of the first 100 nucleotides of enterovirus and rhinovirus RNAs, chimeric constructs in which this region of poliovirus type 1 Mahoney [PV1(M)] is replaced with that of human rhinovirus type 2 (HRV2) or HRV14 have been engineered. These chimeric constructs contain the internal ribosomal entry site of either poliovirus or en...
We report 0.5′′ resolution imaging of the Cloverleaf quasar in the CO(7-6) line and 1.3mm continuum,, as well as 1′′ resolution imaging in the CO(3-2) line, performed with the IRAM interferometer. The CO(7-6) image is clearly resolved into 4 spots, demonstrating that the CO emission is also gravitationally lensed. We do not find any convincing evidence for a velocity gradient in the maps. As co...
The maturation or A-protein gene of single-stranded RNA phage MS2 is preceded by a 130-nt long untranslated leader. When MS2 RNA folding is at equilibrium, the gene is untranslatable because the leader adopts a well-defined cloverleaf structure in which the Shine-Dalgarno (SD) sequence of the maturation gene is taken up in long-distance base pairing with an upstream complementary sequence (UCS)...
