Question: Type II diabetes in the Goto Kakizaki (GK) rats (derived from Wistar rats) is not associated with the development of obesity, hyperlipidemia, hypertension, or pronounced renal functional changes. The aim of this study was to investigate the effect of superimposed hypertension on renal function and morphology under conditions of hyper- and normoglycemia.', 'The evolution of biochemical and morphologic renal changes was examined in GK and Wistar rats treated with deoxycorticosterone acetate (DOCA) salt over 24 weeks.', 'Blood pressure was increased from 6 weeks on in GK and Wistar rats with no difference in blood pressure levels between both groups (week 24, 183 +/- 14 mm Hg vs. 191 +/- 13 mm Hg, P = NS, vs. 144 +/- 6 mm Hg in normal controls, P < 0.01). A progressive increase in proteinuria was observed in hypertensive GK rats from 12 weeks on (week 24, 168 +/- 62 mg/day vs. 41 +/- 30 mg/day in hypertensive Wistar rats, P = 0.002). Histologic analysis at weeks 15 and 24 showed progressive glomerulosclerosis in hypertensive GK and Wistar rats (week 24, 13 +/- 4% vs. 8 +/- 1%, P = NS) but not in nonhypertensive GK controls. This was associated with evidence of podocyte damage (de novo desmin expression) in hypertensive as compared to nonhypertensive GK rats (week 24, score 1.4 +/- 0.1 vs. 0.8 +/- 0.1, P < 0.001) while no significant increase was observed in hypertensive vs. nonhypertensive Wistar rats. Tubulointerstitial damage was increased in hypertensive GK as compared to hypertensive Wistar rats (week 24, score 1.5 +/- 0.6 vs. 0.6 +/- 0.3, P = 0.01). By immunohistochemistry, this was associated with an up-regulation of tubulointerstitial type IV collagen as well as alpha-smooth muscle actin (alpha-SMA) expression, macrophage infiltration and cell proliferation in hypertensive GK rats.

Question: Human and ovine fetuses demonstrate an enhanced rate of spontaneous and angiotensin II-stimulated swallowing. Angiotensin II and nitric oxide synthase have been localized to thirst centers in the brain. This study was performed to determine whether central nitric oxide contributes to the regulation of angiotensin II-induced fetal swallowing.', 'Six pregnant ewes with near-term singleton fetuses were chronically prepared with fetal vascular and lateral ventricle catheters and electrocorticogram and esophageal electromyogram electrodes. After a 2-hour control period, fetuses were administered serial lateral ventricle injections (1 mL) of angiotensin II (3.2 microg; time, 2 hours) and N omega-nitro-L -arginine methyl ester (3 mg; time, 3 hours) and a repeat angiotensin II injection (3.2 microg; time, 5 hours). All fetuses received an additional control study of lateral ventricle injections of artificial cerebrospinal fluid on a previous day.', 'Angiotensin II injection significantly increased mean +/- SEM fetal swallowing (0.9 +/- 0.1 to 2.7 +/- 0.4 swallows/min). N omega-nitro-L -arginine methyl ester significantly decreased fetal swallowing to below the basal rate (0.4 +/- 0.1 swallows/min), and swallowing did not increase with the second angiotensin II dose (in the presence of nitric oxide blockade).

Question: In uterine cervical cancer, certain oncogenic HPV types are considered as key etiologic factor. But the progression of HPV associated cervical precancerous lesions depends on many other factors such as oncogenes, immune system, anti-viral factors etc. This study is therefore focused on the effect of an important dietary anti-viral factor called All Trans Retinoic Acid (ATRA) on the development of HPV associated cervical cancer as it is found higher in poor socioeconomic people.', 'We analyzed a total population of 130 including control subjects who have no complaints of uterine cervical lesions and the HPV-6/11, 16/18 infected cases of low grade squamous intraepithelial lesions [SIL], high grade squamous intraepithelial lesions [HSIL], and invasive cancers, for serum ATRA level. This study also focused to find out the association of serum ATRA level with the proliferation status in terms of proliferating cell nuclear antigen (PCNA) expression as it is an anti-proliferation agent and with the grades of cervical lesions, using SPSS statistical package.', "The results showed a highly significant negative association for serum ATRA level with different stages of cervical lesions (F = 3.305; P = 0.000) by one-way ANOVA and with intensity of PCNA expression (r = -0.825; P < 0.01) by Pearson's correlation test. A highly significant association was observed for the PCNA expression with the grades of cervical lesions too (F = 37.89; P = 0.000). Further, we found from our data that all the invasive cancer cases were infected with HPV-16/18 and none with HPV-6/11. Hence, we analyzed the association of serum ATRA level with HPV-16/18 infected preinvasive cases in developing invasiveness, by Fisher's Exact Test, using Graph Pad Prism as shown in Table 1. The results show an odds ratio (OR) of 36.93 and a relative risk (RR) of 4.99 with an 95% interval being 2.896 to 8.603, which is significant at the level of P = 0.0001 for the reduced [<0.6 mug/ml] serum ATRA level in developing invasive cancer in HPV-16/18 infected preinvasive cases.
