Question: Context: Hypercholesterolemia is a well-established risk factor for the development of kidney injury. Considering that female sex hormones may play a preventative role in both cardiovascular and renal diseases, the aim of the present study was to evaluate the effects of female sex hormones on hypercholesterolemia-induced renal dysfunction.', "Apolipoprotein E-deficient (ApoE) and C57 control female mice underwent an ovariectomy (OVX) or sham surgery and after 2 months, creatinine clearance, uremia and proteinuria were determined. Renal oxidative stress and lipid deposition were also quantified. Values are presented as meanSEM. Statistical analyses were performed using Two-way ANOVA followed by Tukey's post hoc test.", 'Creatinine clearance (L/min) was similar between C57 (17117) and ApoE (14026) mice underwent sham surgery. OVX resulted in a reduced glomerular filtration rate in both C57 (1128, ~-35%, p<0.05) and ApoE (6110, ~-56%, p<0.05) animals. Plasma levels of urea (mg/dL) were higher in both ApoE groups (Sham: 737; OVX: 738, p<0.05) when compared to C57 animals (Sham: 493; OVX: 604), with no changes among ovariectomized groups. Proteinuria levels (mg/24 h) were similar between C57 (Sham: 25.15.7; OVX: 33.74.7) and ApoE sham animals (26.43.5), however, 24-h urine protein excretion was augmented in ApoE OVX animals (49.65.8, p<0.05). Histological kidney analysis demonstrated that the absence of female sex hormones resulted in increased oxidative stress, which was more severe in ApoE mice (C57 Sham: 9.20.4; C57 OVX: 22.91.0; ApoE Sham: 13.90.7; ApoE OVX: 34.01.4 au x 103, p<0.05). As expected, ApoE mice presented higher lipid deposition, which was not affected by OVX (C57 Sham: 00; C57 OVX: 00; ApoE Sham: 6.81.6; ApoE OVX: 5.20.8% x 10-2, p<0.05). Ovariectomy resulted in a similar reduction in ER- protein expression in the renal cortex (C57: 0.780.04; ApoE: 0.810.04 au, p<0.05) when compared to sham animals (C57:1.000.04; ApoE: 1.030.03 au).\Question: Do endogenous female sex hormones delay the development of renal dysfunction in apolipoprotein E-deficient mice?

Answer: Taken together these data indicate that female sex hormones may delay hypercholesterolemia-induced renal dysfunction and emphasizes the importance of plasma cholesterol control in post-menopausal women.

Question: Context: Hypoxia is associated with human non-small cell lung cancers (NSCLC), which are highly resistant to chemotherapy. The hypoxia inducible factor (HIF) as a transcription factor in response to hypoxia indicates that it could be a novel, tumor-specific target for anticancer therapy. We hypothesized that disruption of HIF pathway through lentiviral vector-mediated HIF-1alpha RNA interference (RNAi) could reverse the hypoxia-induced resistance to chemotherapy.', 'We transfected Human NSCLC cell lines, SPCA1 and A549 with HIF-1alpha specific RNAi lentiviral vectors as well as controls. HIF-1alpha silenced cells [SPCA1/HIF-1alpha(-) and A549/HIF-1alpha(-)] were screened by blasticidin. They were incubated in 19 or 0.5% O2 for 16 h followed by the assessment of chemosensitivity to cisplatin and doxorubicin with MTT and clonogenic assays. Quantitative RT-PCR and Western blot analysis were used to detect the expressions of HIF-1alpha mRNA and protein, respectively. Moreover, flow cytometry was used to monitor the expression of P-glycoprotein.', 'Exposure of SPCA1 and A549 cells to 0.5% O2 significantly increased resistance to cisplatin and doxorubicin, in contrast to cells incubated in normoxia. Transduction of SPCA1 with HIF-1alpha RNAi vector resulted in sequence specific silencing with 87.2 and 84.6% decreases of HIF-1alpha mRNA transcription and 97.3 and 94.8% of protein expressions in normoxia and hypoxia, respectively. Correspondingly, they are 89.2, 89.9% and 97.2, 88.4% decreases in A549 cells. Hypoxia-induced resistance to cisplatin and doxorubicin were reversed in SPCA1/HIF-1alpha(-) and A549/HIF-1alpha(-) cells. There was no significant P-glycoprotein increase induced by hypoxia in NSCLC cells.\Question: Is hypoxia-induced resistance to cisplatin and doxorubicin in non-small cell lung cancer inhibited by silencing of HIF-1alpha gene?

Answer: Our studies demonstrated that hypoxia-induced chemoresistance to cisplatin and doxorubicin in NSCLC cells is through the HIF pathway. MDR1 regulation may not be involved in hypoxia-induced chemoresistance. Combining delivery of HIF-1alpha RNAi lentiviral vector with cisplatin-related chemotherapy regimens may enable us to develop more effective strategy for NSCLC therapy.

Question: Context: The prevalence of interstitial cystitis (IC) in young women, especially in those 18 years old or younger, is not well defined. This case series was performed to investigate IC as a cause of chronic pelvic pain (CPP) in young women.', 'Case series.', 'University medical center.', 'Twenty-eight women with CPP, ages 13 to 25, who underwent concomitant laparoscopy and cystoscopy.', 'All subjects underwent concomitant diagnostic laparoscopy and cystoscopy with hydrodistension for evaluation of CPP. Charts were reviewed to discern preoperative symptoms, operative findings, and postoperative diagnoses.', 'Diagnosis of IC based on symptoms and cystoscopic findings.', 'All 28 women had CPP, 23 (82%) had dysmenorrhea, and 12 of 25 (48%) sexually active subjects had dyspareunia. Twenty-six subjects (93%) had urinary symptoms including frequency (75%), nocturia (32%), urgency (25%), and dysuria (18%). Eleven (39%) subjects were diagnosed with IC and 18 (64%) with endometriosis, including 7 (25%) subjects with both IC and endometriosis. Laparoscopic findings were normal in 6 (21%) subjects. Of the 26 subjects with urinary symptoms, 21 (81%) had findings on laparoscopy or cystoscopy. In this cohort of young women with chronic pelvic pain, urinary frequency and dyspareunia were significantly associated with the diagnosis of IC.\Question: Is interstitial cystitis an etiology of chronic pelvic pain in young women?

Answer:
The results of this study suggest that interstitial cystitis is an etiology of CPP in young women. Evaluation of the bladder as an origin of pelvic pain is warranted in young women with CPP and urinary frequency or dyspareunia.
