PURPOSE To determine the effect of ranibizumab on visual acuity (VA) following a 3-year treatment period for patients diagnosed with wet age-related macular degeneration. To establish whether baseline VA and injection frequency influence visual outcomes. PATIENTS AND METHODS Retrospective review of 70 patients (76 eyes) treated with 0.5 mg intravitreal ranibizumab for 3 consecutive months, an...

BACKGROUND This pilot study compared a monophasic hyaluronic acid dermal filler with a biphasic filler for the correction of nasolabial folds. METHODS Participant- and assessor-blinded, randomized clinical trial involving participants with moderate to severe nasolabial folds. Split-face design comparing a monophase hyaluronic acid (HA) filler (mono-HA) with a biphasic HA filler (bi-HA). Injec...

In view of the problem that water cut rises quickly in conglomerate reservoirs with high cut, based on variation law reservoir injection and liquid production characteristics, a method for determining maximum scale is established by using engineering field statistics.Considering capacity at well end, end injecting-production ratio limit to keep formation energy, determine energy sufficient.This...

AIM To report on clinical outcome and complications of intravitreal injection of crystalline cortisone in patients undergoing pars plana vitrectomy for treatment of proliferative vitreoretinopathy. METHODS The study included all 16 patients who underwent pars plana vitrectomy for treatment of proliferative vitreoretinopathy, who received an intravitreal injection of 10-20 mg crystalline triam...

Wrong-route or -patient medication errors due to human mistakes have been considered difficult to resolve in clinical settings. In this study, we suggest a safety injection system that can help to prevent an injection when a mismatch exists between the drug and route or patient. For this, we prepared two distinct adapters with key and keyhole patterns specifically assigned to a pair of drug and...

BACKGROUND The interest of low molecular weight heparins (LMWH) regarding bleeding risk is controversial in renal failure patients. In haemodialysis patients, there are very few data on the pharmacokinetics of LMWH after the end of the session. The aim of the study was to evaluate the duration of anticoagulation after bolus administration of the LMWH enoxaparin at the start of haemodialysis. ...

This study aims to evaluate the safety and efficacy of intravitreal bevacizumab (IVB) at the end of vitrectomy in prevention of rebleeding in patients with diabetic vitreous hemorrhage. Methods: This is a retrospective interventional study comprised of 30 eyes from 30 patients who underwent 23 G pars plana vitrectomy for diabetic vitreous hemorrhage (VH). IVB (1.25 mg/0.05 ml) was injected at t...

The aim of the current study is to evaluate the effects of inhibitors or solvents on asphaltene precipitation under reservoir conditions. To this end, the interaction between live oil and solvent, and its side effects on precipitated/dissolved asphaltene were predicted via Miller’s entropy modified polymer solution theory under reservoir conditions. Then, the adjustable parameters of the model ...

Warpage and shrinkage control are important factors in proving the quality of thin-wall parts in injection modeling process. In the present paper, grey relational analysis was used in order to optimize these two parameters in manufacturing plastic bush of articulated garden tractor. The material used in the plastic bush is Derlin 500. The input parameters in the process were selected according ...
