BACKGROUND AND OBJECTIVES Concern for block-related injury and liability has dissuaded many anesthesiologists from using regional anesthesia for eye and extremity surgery, despite many studies demonstrating the benefits of regional over general anesthesia. To determine injury patterns and liability associated with eye and peripheral nerve blocks, we re-examined the American Society of Anesthesi...

Glaucoma management aims to preserve patients' quality of life by halting progressive visual loss. Intraocular pressure reduction is the pivotal strategy: we establish a "target" pressure based on extent of visual damage, threat to visual performance, risk profile for further damage, pre-treatment pressure levels, family history and a patient's life expectancy. Once an acceptable treatment regi...

The DNA is cells is continuously exposed to reactive oxygen species resulting in toxic and mutagenic DNA damage. Although the repair of oxidative DNA damage occurs primarily through the base excision repair (BER) pathway, the nucleotide excision repair (NER) pathway processes some of the same lesions. In addition, damage tolerance mechanisms, such as recombination and translesion synthesis, ena...

In pursuit of p-type doping, we have implanted GaN with Mg ions at 200 and 500 keV with the substrate temperature maintained at −150 cold or +300 °C hot during ion irradiation. The samples have been annealed at 1000 °C postion implantation. The radiation damage peak position and its profile , the dopant distribution, and the damage stability during annealing were all shown to be dependent upon ...

Impaired oxidant/antioxidant status in hypertension results in increased oxidative stress. This may cause genomic instability, damage membrane proteins and lipid peroxidation in hypertensive individuals. Aim: The aim of this study was to assess genomic instability (DNA damage) and lipid peroxidation in treated hypertensive patients belonging to a population sub-group. Materials and Methods: A c...

The tendency to reduce crude protein (CP) levels in pig diets to increase protein efficiency may increase the occurrence of damaging behaviours such as ear and tail biting, particularly for pigs kept under suboptimal health conditions. We studied, in a 2×2×2 factorial design, 576 tail-docked growing-finishing entire male pigs in 64 pens, subjected to low (LSC) vs. high sanitary conditions (HSC)...

The International Roughness Index (IRI)'s survey is a longitudinal profile to determine of road. purpose this provide an overview road conditions and input in optimizing the maintenance rehabilitation existing roads city Palangka Raya. data used for analysis IRI’s from surveys on several that represent Raya City with RoadLabPro application car. results showed Beruk Angis had average IRI value 9...

Orifice spillways might be affected by cavitation if the profile of the inlet structure includes a relevant curvature. At one of the world’s largest dams, such damages were observed on the profiled slab. To limit their progression, an adapted operation regime of the gates had to be defined using physical model tests. The risk estimation was based on dynamic pressure and velocity measurements, i...

background: liver cirrhosis is an end-stage condition fornumerous chronic liver diseases. limited data exists on the epidemiology,natural history and complications of liver cirrhosis in ahvaz, iran. in a cross-sectional study we have retrospectively evaluated 165 patients from september 1, 1999 until september 1, 2008. materials and methods: patients with evidence of cirrhosis of the liver seen...
