PURPOSE The purpose of this study was to assess the ability of quantitative in vivo confocal microscopy (CM) to detect changes in cystine crystal volume in the cystinosisn (Ctns(-/-))mouse cornea following topical cysteamine therapy. METHODS Fifteen Ctns(-/-) mice were sequentially followed using in vivo CM from 3 to 10 months of age. In a second experiment, five mice receiving topical cystea...

BACKGROUND AND OBJECTIVES Clinical management of mineral bone disorder in patients with kidney failure is guided by biochemical targets, in particular parathyroid hormone (PTH) concentration. The biologic variation of PTH and other bone mineral markers was measured in hemodialysis patients to better define their role in management. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Intact PTH, bio...

Background: Use of human embryonic stem cells (hESCs) has been explored for treatment of cortical visual impairment (CVI) in children with cerebral palsy (CP). Objectives: The study evaluated efficacy and safety of hESC therapy in 40 CP children with CVI. Methods: The study had four treatment phases (T1, T2, T3, and T4) separated by gap phases. Patients were evaluated for visual impairment usin...

We analyzed the natural genetic variation between Landsburg erecta (Ler) and Cape Verde Islands (Cvi) accessions by studying 105 recombinant inbred lines to search for players in the regulation of sensitivity to light signals perceived by phytochromes in etiolated seedlings of Arabidopsis. In seedlings grown under hourly pulses of far-red (FR) light, we identified three quantitative trait loci ...

BACKGROUND Nocturnal hypoventilation is associated with chronic ventilatory insufficiency (CVI). Noninvasive mechanical ventilation (NIV) performed overnight relieves symptoms of hypoventilation and improves daytime blood gases in CVI. In order to test whether the efficacy of NIV depends on its being applied during sleep we conducted a prospective case controlled study comparing daytime mechani...

Sugar-induced anthocyanin accumulation has been observed in many plant species. We observed that sucrose (Suc) is the most effective inducer of anthocyanin biosynthesis in Arabidopsis (Arabidopsis thaliana) seedlings. Other sugars and osmotic controls are either less effective or ineffective. Analysis of Suc-induced anthocyanin accumulation in 43 Arabidopsis accessions shows that considerable n...

We aimed to assess the efficacy of Centella asiatica for improvement of the signs and symptoms of chronic venous insufficiency (CVI). We searched 13 electronic databases including the Cochrane Central Register of Controlled Trials for randomised controlled trials assessing the efficacy of Centella asiatica for CVI. Two review authors independently selected studies, assessed the risks of bias of...

Recent studies suggest that cross-talk between salicylic acid (SA)-, jasmonic acid (JA)-, and ethylene-dependent signaling pathways regulates plant responses to both abiotic and biotic stress factors. Earlier studies demonstrated that ozone (O(3)) exposure activates a hypersensitive response (HR)-like cell death pathway in the Arabidopsis ecotype Cvi-0. We now have confirmed the role of SA and ...
