Applying high voltage to an ion-conducting glass at high temperature is equivalent to electrolyse a glass. We observed several morphologies of electro-deposited silver and other conducting ions on dc ...biasing of silver metaphosphate glass. One of the findings is that electro-deposited silver underneath the gold cathode pushed up the cathode.
IgA nephropathy (IgAN) is the most common form of chronic glomerulonephritis with IgA deposits present mainly in the mesangial areas. We performed a 10-year retrospective case-control study of 71 ...patients with IgAN to evaluate the long-term effects and prognostic factors associated with tonsillectomy. Forty-one patients (19 males and 22 females) underwent tonsillectomy (Group A) and 30 patients (13 males and 17 females) did not (Group B). These patients were followed for more than 10 years after renal biopsy. The average age at initial renal biopsy was 29.78 years in Group A and 33.0 years in Group B. The average follow-up period was 13 years and 3 months in Group A, and 12 years and 7 months in Group B. Glomerular damage demonstrated on renal biopsy was more extensive in Group A than in Group B. Prognosis after 10 years of follow-up was compared between the two groups. The clinical remission rate was 24.4% in Group A and 13.3% in Group B, the stable renal function rate was 82.9% in Group A and 70.0% in Group B, and the renal survival rate was 95.1% in Group A and 73.3% in Group B. The renal survival rate in Group A was significantly higher than that in Group B (p <0.05). Although evaluation of renal pathology based on renal biopsy was useful in predicting the long-term effects of tonsillectomy in IgAN patients, the results of tonsillar provocation tests were not.
We investigated the effects of a Chinese herbal medicine, Gosha-jinki-gan (GJG), on the regulation of insulin levels in rats fed a sucrose-rich diet (SRD). Normal Wistar rats in the SRD group were ...fed an SRD for 4 weeks. Increased dietary sucrose did not alter plasma glucose levels but it increased plasma insulin levels at 2 and 4 weeks in the SRD-fed rats relative to control rats that were fed standard chow. GJG treatment significantly suppressed the SRD-induced elevation in plasma insulin levels. These results suggest that GJG improves hyperinsulinemia caused by an SRD.
AIMS
To compare the efficacy of remnant ablation following a single low dose (specific activity of 131I administered, 1074–1110 MBq) vs. a single high dose (mostly 2775–3700 MBq) of 131I in patients ...with differentiated thyroid cancer and to determine whether or not the extent of surgery influences outcome.
METHODS
Nineteen studies have reported the results of low dose 131I ablation. Of these, 11 met our criteria for a comparative analysis. Two additional cohorts of ours were added and these were analysed in two groups based on the extent of surgery (near‐total NT; Woodhouse1 vs. sub‐total ST; Woodhouse2). There were 518 low dose and 449 high dose patients in all.
RESULTS
The average failure of a single low dose was 46 ± 28% (SD). Meta‐analysis revealed a statistically significant advantage for a single high over a single low dose and a pooled reduction in relative risk of failure of the high dose of about 27% (P < 0.01). From this we estimate that for every seven patients treated one more would be ablated given a high rather than a low dose (assuming a low dose failure risk of 50%). Also, a significantly greater proportion of patients are ablated after a single high or low dose, if they underwent near‐total as opposed to sub‐total thyroidectomy (summary relative risk (RR) 1.4; P < 0.05).
CONCLUSION
High dose 131I is more efficient than low dose for remnant ablation particularly after less than total thyroidectomy. Results suggest that patients with differentiated thyroid cancer should routinely have a total thyroidectomy followed by high dose 131I (2775–3700MBq) for ablation of the remnant.
Ktenasite was synthesized by the simple method of mixing ZnO powder with CuSO
4 solution at room temperature. The X-ray diffraction pattern of synthesized ktenasite was very similar to that of ...mineral ktenasite. The lattice parameters were determined as
a=0.559,
b=0.616,
c=2.374
nm and
β=95.63°, which agreed comparatively well with those for mineral ktenasite. The synthesized ktenasite consisted of thin rectangular particles ranging in size from 2 to 4
μm in length. TEM observation suggested the formation of a super lattice structure in the
a-axis direction and significant crystal growth in the
b-axis direction. The intercalation reaction of sodium dodecyl sulfate (NaDS) with ktenasite showed that the intercalation took place accompanied by the expansion of basal spacing from 1.17 to 2.70
nm. The reaction progressed by the SO

− anion exchange mechanism with the dissolution of interlayer Zn(H
2O)
