Chronic A1 and A2b adenosine receptor blockade improves diabetes and attenuates renal and cardiac histopathology in animals with the metabolic syndrome

Chronic A1 and A2b adenosine receptor blockade improves diabetes and attenuates renal and cardiac histopathology in animals with the metabolic syndrome
Few therapies are known to enhance diastolic function. Systemic administration of natriuretlc peptldes (NP) improves diastolic function. However, this may be due to effects on load, rather than a direct myocardlal action. We generated mice with acar-disc-specific (a-MHC promoter) gain-of-function mutation (GoF, HCAT E974A) in the natriuretic peptide A receptor (NPRA) resulting in myocyte-specific constitutive NPRA activation. We hypothesized that ... Read more

Lesional and circulating levels of interleukin‐17 and 25‐ hydroxycholecalciferol in active acne vulgaris: Correlation to disease severity

Lesional and circulating levels of interleukin‐17 and 25‐ hydroxycholecalciferol in active acne vulgaris: Correlation to disease severity
bjectives: The immunological aspects of inflammatory acne are still incompletely understood, so this study aimed to investigate the possible role of IL‐17 and 25 hydroxycholecalciferol (25(OH)D3) in the disease pathogenesis and progression. Materials and Methods: Across‐sectional study has been conducted on 135 patients with active acne vulgaris of various severities and 150 matched controls. ELISA assays of serum and tissue ...

Trabeculectomy with collagen matrix implantation versus trabeculectomy with mitomycin C application for the treatment of primary congenital glaucoma

2018-09-20 13:06:31 Keywords Mitomycin C, Ologen implants, ,
Trabeculectomy with collagen matrix implantation versus trabeculectomy with mitomycin C application for the treatment of primary congenital glaucoma
PURPOSE To compare the results in terms of the efficacy and safety of collagen matrix implant [Ologen (OLO) implant] versus mitomycin C (MMC) in trabeculectomy for the surgical treatment of primary congenital glaucoma. MATERIALS AND METHODS Twenty eyes of 15 patients with primary congenital glaucoma were divided into two groups. The first group (MMC group) included 10 eyes that were ... Read more

Analysis of 2-year corneal cross-linking results in keratoconus patients
PURPOSE To analyze the results of 2 years of corneal collagen cross-linking (CXL) for the treatment of keratoconus and to detect the efficiency of this procedure. DESIGN This was a retrospective noncomparative study. PATIENTS AND METHODS A total of 58 eyes of 40 keratoconus patients were subjected to CXL. Epithelium-off CXL was the only procedure performed for all cases. The ... Read more

Evaluation of the therapeutic effect of corneal collagen cross-linking in the treatment of resistant corneal ulcer
PURPOSE The aim of this study was to evaluate the therapeutic results of corneal collagen cross-linking (CXL) in terms of safety and efficacy in the treatment of resistant corneal ulcer. DESIGN This study was designed as a noncomparative prospective clinical trial. PATIENTS AND METHODS Five eyes of five patients with resistant corneal ulcers that failed to heal after maximal topical ... Read more

Comparison of epithelium-off and transepithelial corneal collagen cross-linking for treatment of keratoconus

2018-09-20 13:13:57 Keywords cross-linking, epithelium-off, ,
Comparison of epithelium-off and transepithelial corneal collagen cross-linking for treatment of keratoconus
PURPOSE The aim of the study was to assess the safety and efficacy of epithelium-off corneal cross-linking (conventional cross-linking) versus epithelium-on cross-linking (epithelium-on cross-linking) in the treatment of keratoconus. PATIENTS AND METHODS This study was a nonrandomized comparative trial. Forty-three eyes of 35 patients were included in this study. All eyes were subjected to the preoperative and postoperative measures including ... Read more

Optimal allocation of renewable dg sources in distribution networks considering load growth
The annual increasing of load demand in electrical distribution networks leads to line congestion, decreasing the bus voltages below the acceptable limits and increasing the active and reactive power losses. However, renewable distributed generation (DG) has received increasing attention due to that growing in load demand. This paper presents a hybrid method based on moth-flame optimization (MFO) algorithm with loss ... Read more
