Structures of the SEp22 dodecamer, a Dps-like protein from Salmonella enterica subsp. enterica serovar Enteritidis
The crystal structure of SEp22, a DNA-binding protein from starved cells from Salmonella enterica subsp. enterica serovar Enteritidis, has been determined in two forms: the native state at 1.25 Ă
resolution and an iron-soaked form at 1.30 Ă
resolution. The SEp22 protomers form a dodecameric shell with 23 symmetry and a single iron ion per protomer was found at the ferroxidase centre in the iron-soaked form. Along the threefold axes of the 23 symmetry, hydrophilic Asp channels that consist of Asp146 were found. Iron ions may flow into the cavity of the dodecameric shell through the Asp channels

The Utility of Post-Void Residual Volume versus Sphincter Electromyography to Distinguish between Multiple System Atrophy and Parkinson's Disease.
To determine the ability of sphincter electromyography (EMG) and post-void residual urine volume (PVR) during a free-flow study and a pressure-flow study (PFS) for distinguishing multiple system atrophy (MSA) from Parkinson's disease (PD).We retrospectively reviewed 241 case records; both urodynamic study and sphincter EMG were performed in patients with MSA (n = 147) and PD (n = 94).There was a statistically significant difference (p < 0.01) in the mean PVR during the free-flow study (113.1 ± 7.5 mL in MSA and 40.4 ± 3.8 mL in PD), mean PVR during PFS (230.1 ± 12.6 mL in MSA and 71.7 ± 6.6 mL in PD), and mean duration of MUP for sphincter EMG (9.3 ± 0.1 ms in MSA and 7.7 ± 0.1 ms in PD). The area under the curve used for differentiating MSA from PD was 0.79 and 0.73 for PVR during PFS and the free-flow study, respectively. There was a mean duration of 0.69 ms for the sphincter EMG.The present results suggested that PVR was more appropriate than sphincter EMG for differentiating MSA from PD
Urinary Dysfunction in Progressive Supranuclear Palsy Compared with Other Parkinsonian Disorders.
BACKGROUND:Autonomic urinary dysfunction affects patients with progressive supranuclear palsy (PSP); however, the severity and prevalence of urinary dysfunctions in these patients compared with those observed in patients with Parkinson's disease (PD) and multiple system atrophy (MSA) are unknown. OBJECTIVE:We compared urinary dysfunction characteristics in patients with PSP, PD, and MSA. PATIENTS AND METHODS:Forty-seven patients who satisfied the probable or possible criteria of the National Institute for Neurological Diseases and Stroke and Society for PSP were assessed using the urinary symptoms questionnaire and the urodynamic study at Chiba and Toho Universities (n = 26 and 21, respectively). The results were compared with those of patients with PD and MSA (n = 218 and 193, respectively). RESULTS:The mean disease duration of PSP and the mean age were 2.97 ± 0.26 and 71.4 ± 0.88 years, respectively. The mini-mental state examination and frontal assessment battery scores were 22.6 ± 0.70 and 10.7 ± 0.49, respectively. Urinary storage and voiding symptoms were observed in 57% and 56% of patients with PSP, respectively. Detrusor overactivity in the urodynamic study was detected in 81% of patients with PSP, which was slightly more than that found in patients with PD (69%) and MSA (67%); however, this was not statistically significant. Postvoid residual volume in patients with PSP was significantly more than that in patients with PD (P < 0.01), but was equivalent to that in patients with MSA. CONCLUSIONS:The present study demonstrated that patients with PSP experienced various urinary dysfunctions. Urinary storage dysfunction in patients with PSP was not different from that in patients with PD or MSA, whereas urinary voiding dysfunction in patients with PSP was milder than that in patients with MSA and more severe than that in patients with PD. These features should be taken into account for the differentiation of PSP from PD and MSA
Systemic administration of the antisense oligonucleotide NSâ089/NCNPâ02 for skipping of exon 44 in patients with Duchenne muscular dystrophy: Study protocol for a phase I/II clinical trial
Abstract Aim The purpose of this study is to evaluate the safety and pharmacokinetics of the novel morpholino oligomer NSâ089/NCNPâ02 which can induce exon 44 skipping, in patients with DMD. Additionally, we aimed to identify markers predictive of therapeutic efficacy and determine the optimal dosing for future studies. Methods This is an openâlabel, doseâescalation, twoâcenter phase I/II trial in ambulant patients with DMD, presence of an outâofâframe deletion, and a mutation amenable to exon 44 skipping. Part 1 is a stepwise doseâfinding stage (4âweeks) during which NSâ089/NCNPâ02 will be administered intravenously at four dose levels once weekly (1.62, 10, 40, and 80âmg/kg); Part 2 is a 24âweek evaluation period based on the dosages determined during Part 1. The primary (safety) endpoints are the results of physical examinations, vital signs, 12âlead electrocardiogram and echocardiography tests, and adverse event reporting. Secondary endpoints include expression of dystrophin protein, motor function assessment, exon 44 skipping efficiency, plasma and urinary NSâ089/NCNPâ02 concentrations, and changes in blood creatine kinase levels. Discussion Exonâskipping therapy using ASOs shows promise in selected patients, and this firstâinâhuman study is expected to provide critical information for subsequent clinical development of NSâ089/NCNPâ02
