Hyperbaric oxygen (HBO2) therapy is an established intervention for treating chronic diabetic lower extremity ulcers, but the impact of glycemic control on its efficacy has not been determined. The purpose of this study was to evaluate the impact of blood glucose control at initiation of HBO2 treatment on wound healing. Hemoglobin A1c (HbA1c) was measured at start of HBO2 therapy for 22 patients undergoing treatment of chronic lower extremity ulcers at two regional wound care centers. Patients with HbA1c < 7.5% were stratified into a "good glycemic control" group (n = 12, mean HbA1c 6.5 ± 0.8%), and patients with HbA1c ≥ 7.5% were stratified into a "poor glycemic control" group (n = 10, mean HbA1c 8.8 ± 1.4%, p = 0.004 compared to "good glycemic control group"). After 20 HBO2 sessions over 30 days in addition to standard wound care interventions, there was no difference in wound healing between the two glycemic control groups as indicated by reduction from baseline in ulcer surface area, depth, or volume. The diabetic lower extremity wound response to HBO2 therapy is unaffected by glycemic control prior to treatment, and HBO2 treatment should not be delayed for suboptimal blood glucose control.

Mineral recources mining can cause a number of problems, which are fully described and prognosed in the article. The problems consist in the weak base, existing in the slopes, that can lead to the bedding of the slope base. There are two possible methods of calculating of the parametres that can prevent such problem as bedding. These methods are numerical and analytical. The more detailed explanation of these methods has been given in the article. © 2014 IEEE.

Sweet sorghum has been identified as a promising feedstock for biological conversion to fuels as well as other chemicals. The lignocellulosic stalk of sweet sorghum, called sweet sorghum bagasse (SSB) is a potential source of lignocellulosic biofuel. The primary goal of this study was to determine optimal alkali (lime: Ca(OH)2 and lye: NaOH) pretreatment conditions to obtain higher yield of total reducing sugar while reducing the lignin content for biofuel production from SSB. Biomass conversion and lignin removal were simultaneously optimized through four quadratic models analyzed by response surface methodology (RSM). The optimal conditions for lime pretreatment was 1.7% (w/v) lime concentration, 6.0% (w/v) SSB loading, 2.4h pretreatment time with predicted yields of 85.6 total biomass conversion and 35.5% lignin reduction. For lye pretreatment, 2% (w/v) alkali, 6.8% SSB loading and 2.3h duration were the optimal levels with predicted biomass conversion and lignin reduction of 92.9% and 50.0%, respectively. More intensive pretreatment conditions removed higher amounts of hemicelluloses and cellulose. Fourier transform infrared spectroscopy (FTIR) spectrum and scanning electron microscope (SEM) image revealed compositional and microstructural changes caused by the alkali pretreatment. © 2015 Elsevier B.V.

This paper goes for a simple but elaborate measurement of the sensitivity of human health due to the radiation of mobile phone while using it. The possible risks by radio frequency electromagnetic field exposure of the human body are a major concern for the society. If exposure is sufficiently intense, it can cause biological effects. The increasing use of mobile phone in our environment it is one of the reasons why many scientists believe some disease rates are on the rise. It is scientifically proved that the radiations produced by the mobile phones affect especially the brain of human being and it will give them the difficulty to cope up with their systematized daily course of action and soon cause health injury. In this paper, it has been shown that there lies a tangible congruence of the result of statistical analysis based on an extensive survey all over Bangladesh on different level of mobile users with the hazards. © 2005 - 2010 JATIT.
