Q: Context: To determine the role of herpes simplex virus-1 (HSV-1) glycoprotein K(gK) in corneal infection, neuroinvasion, and virus latency in trigeminal ganglia of mice.', 'The recombinant virus HSV-1 (McKrae) Delta gK (MKDelta gK) carrying a deletion of the gK gene was constructed by insertional/deletion mutagenesis and replaced by a gene cassette constitutively expressing the enhanced green fluorescence protein. The gK deletion of the MKDelta gK virus was rescued to produce the wild-type-like virus MKgK. Balb/c mice were infected ocularly with either virus, and the infection pattern in the eye, clinical disease progression, and establishment of viral latency was monitored.', 'Mice infected with the MKDelta gK strain produced in a gK complementing cell line did not exhibit clinical signs when compared with mice infected with the MKgK virus. Direct visualization of infected eyes revealed that the MKDelta gK virus was unable to spread in mouse corneas, while the MKgK rescued virus spread efficiently. Nineteen of 20 scarified and 5/12 unscarified mice infected with the MKgK virus produced infectious virus after coculture with permissive cells, while 0/20 scarified and 0/12 unscarified mice infected with the MKDelta gK virus produced infectious virus. HSV DNA was detected in trigeminal ganglia by PCR in 19/20 scarified and 9/12 unscarified mice inoculated with MKgK, while HSV DNA was detected in the trigeminal ganglia of 3/20 scarified and 0/12 unscarified mice inoculated with MKDelta gK.
Answer: The results show that HSV-1 gK is essential for efficient replication and spread in the corneal epithelium and trigeminal ganglia neuroinvasion in MKDelta gK inoculated mice.

Q: Context: To study the role of peroperative transrectal ultrasonography (peTRUS) for the dissection of the bladder neck during robot-assisted laparoscopic prostatectomy (RALP).', 'Integrated peTRUS in the da Vinci S system (Intuitive Surgical, Sunnyvale, CA, USA) was used for bladder neck identification and dissection in the initial 80 patients with clinically localized prostate cancer operated by two urologists. The clinical and pathological results were compared with the initial 80 patients who had RALP with no peTRUS. The location of positive margins was recorded.', "The operative duration, blood loss, hospital stay, catheter dependency, clinical and pathological T-stage and Gleason sum score were no different between the groups. The prostate-specific antigen level at time of diagnosis was slightly higher for patients in the peTRUS group. Basal surgical margins (bladder neck and basal areas of both prostate lobes) were positive for tumour in 9.1% and 2.3% of patients treated without and with peTRUS, respectively (P = 0.001). Although the use of peTRUS improved the basal margin rate in the initial 30 patients in each group, it did not in the last 30 in each group, when the urologist's experience apparently improved. In a multivariate analysis the use of peTRUS and pathological T-stage were the best predictors of basal margin status. Pad use at 6 months after surgery was similar for both groups.
Answer: peTRUS during RALP decreased the positive surgical margin rate at the base of the prostate during the initial experience of RALP.

A: Does peroperative transrectal ultrasonography-guided bladder neck dissection ease the learning of robot-assisted laparoscopic prostatectomy?

Q: Context: The proteasome is the proteolytically active core of the ubiquitin-proteasome system, which regulates vital processes and which can cause various diseases when it malfunctions. Therefore, the proteasome has become an attractive target for pharmaceutical interventions. Inhibition of the cardiac proteasome by specific proteasome inhibitors has been shown to attenuate cardiac hypertrophy and ischaemia reperfusion injury of the heart. We have resolved the cardiac proteasome into its subtypes and have addressed the key question of how proteasome inhibitors affect single cardiac proteasomal subtypes.', 'The 20S proteasome from rat heart was dissected into three different subpopulations (groups I-III), each comprising 4-7 different subtypes. The major group (group II) comprises standard proteasome subtypes; the two minor subpopulations (groups I and III) contain intermediate proteasome subtypes. All subtypes exhibit chymotrypsin-, trypsin-, and caspase-like activity but to different degrees. We have tested the effect of two common proteasome inhibitors on the chymotrypsin-like activity of all subtypes: 20-30 nmol/L MG132 caused 50% inhibition of all subtypes from groups I and II, whereas 100 nmol/L was necessary to affect group III subtypes to the same extent. However, another inhibitor, bortezomib (VELCADE), already used clinically, inhibited 50% of the activity of group III proteasome subtypes even below 20 nmol/L, a concentration showing almost no effect on group I and II proteasome subtypes. The caspase-like activity of group II proteasome subtypes was not affected by MG132 and was inhibited by bortezomib only at concentrations above 100 nmol/L.
Answer: These data show that different inhibitors have differential inhibitory effects on the various cardiac proteasome subtypes. Different cardiac subtypes are inhibited by the same dose of proteasome inhibitor to a different extent.

A:
Do multiple cardiac proteasome subtypes differ in their susceptibility to proteasome inhibitors?
