Background: To investigate the indications of loop electrosurgical excision procedure (LEEP) and its overtreatment rates for the see and treat and three step strategies in cases of atypical squamous cells of undetermined cytology (ASC-US) and low grade intraepithelial neoplasia (LGSIL) cytology. Materials and Methods: We retrospectively analyzed colposcopy directed biopsy (CDB) and LEEP results of 176 paients with ASC-US or LGSIL cytologies who underwent colposcopic examination. Results: Initial cytologies were ASCUS in 120 women and LGSIL in 56. According to the see and treat approach immediate LEEP was performed for38 women. Among the remaining 138 women, LEEP was performed for 32 whose CDB results revealed CIN2/3 lesions. In the see and treat group the recognition of CIN2/3 was found to be 39.4%. The overtreatment rate was 60% as compared to 25% in the three step group. In CDB group detection of CIN 2 or greater lesions increased with 3 or more biopsies. Conclusions: In patients with ASC-US/LGSIL cytologies CDB should be performed before LEEP to prevent overtreatment, with attention to all suspected areas and more than 2 biopsies taken.

The treatment of dyeing wastewater is not easy because dyes are mainly aromatic, heterocyclic compounds. The most effective technologies and methods to treat dyeing wastewater are costly and involve materials that are difficult to regenerate after use. Therefore, it is necessary to develop cost-effective, eco-friendly technologies to treat dyeing wastewater. The aim of this study was to investigate the removal of sulfur blue 11 (CI 53235) anionic dye using methyl esterified sericite (ME-sericite) adsorbents in an aqueous solution. The results are discussed in terms of the ME-sericite particle size, temperature, pH value and initial sorption rate according to the initial sulfur blue concentration. In addition, we analyzed the adsorption kinetics using a Pseudo-second-order model with the desorption and reusability. The methyl esterification caused a considerable increase in the specific surface area from 4.45 to $17.62m^2/g$. The ME-sericite adsorbents successfully removed > 98% of the sulfur dye in the aqueous solution. For the adsorption of 1 mg of sulfur dye, approximately 4.6 to 6.6 g/L ME-sericite were required. The desorption process was carried out by mixing a NaOH eluent to desorb 90.56% of the sulfur dye with 2 h of contact time. Thus, the ME-sericite is a promising adsorbent to treat dyeing wastewater due to its low dose requirement, high removal efficiency and inexpensive material.

The petrochemical products can cause soil and groundwater contamination during their transportation and the use of the products, and while being contained in underground storage tanks(USTs) throughout the leakage. To treat the contaminated soil, the bioventing method is suitable for the remediation of semi-volatile compounds, such as diesel and kerosene. Biofiltration is one of possible method to treat the off-gas produced in the process of the bioventing. This study is related to the usage, effectiveness of treatment, and feasibility of two types of biofilter system made of ceramic-compost and polymer respectively to treat diesel VOCs at constant retention time of 20 sec. Compost biofilter showed the average removal efficiency of 73 % when the inlet concentration increased to 20 ppmv. Increased the inlet concentration decreased the microbial activities as well as the removal efficiency. On the contrary, the removal efficiency of the polyurethane biofilter was maintained at 88 % at the inlet concentration of 13 ppmv during ten days and was obtained to 80 % at the inlet concentration of 30 ppmv in spite of the drop of the efficiency in the sudden increase of the inlet concentration. At the beginning of the experiment it showed low removal efficiency at low inlet concentration due to the low microbial activity, however, as experiments proceed the removal efficiency could be obtained more than 80% at high inlet concentration.

Ti6Al4V alloy have been mainly used as implant materials. Ti-6Al-4V alloy instead of pure Ti is being widely used as biomaterials has some characteristics such as high fatigue strength, tensile strength. But it has been reported recently that vanadium component expresses cytotoxicity and carcinogenicity and aluminium component is related with dementia of Alzheimer type. In order to overcome their detrimental effects, $\beta$-phase stabilizer Nb was chosen in the present study, in addition Ta and Hf were added to Ti-40wt.%Nb alloy to improve its mechanical properties. This paper was described the influence of heat treatment of Ti-40Nb alloys with 2wt%Ta, 2wt%Hf on the mechanical properties. Specimens of Ti alloys were melted in vacuum arc furnace and homogenized at 1050$^{\circ}C$ for 24 hr. and then were aged after solution heat treat at $\alpha+\beta$ and $\beta$ regions. The mechanical properties of Ti alloys were analysed by hardness test, tensile test, elongation test and SEM test. The results can be summarized as follows: 1. The mechanical properties Ti-40wt.%Nb were improved when 2wt.% Ta and 2wt.%Hf were added. 2. The higher tensile strength value and elongation at solution heat treat was higher than solution heat treat and then were aged.

Background: To evaluate the overtreatment rate with the see and treat approach in the management of women with abnormal cervical cytology. Materials and Methods: A retrospective review of patients with abnormal cervical cytology who underwent S&T at MSMC between January 2008 and December 2012 was conducted. Loop electrosurgical excision procedure (LEEP), histological results, cytology and colposcopic impression were analyzed to evaluate overtreatment rate, cyto-histologic correlation and related factors. Results: Average age of S&T cases was 42 years. Ninety seven percents were referred from affiliated health care providers. The study revealed 83.2% patients had HSIL or higher from cervical cytology. Correlation between HSIL and final histology was relatively low at 75% compared to other studies. Overtreatment rate was 28%. Conclusions: S&T was done in 197 patients in a tertiary care health facility with patient satisfaction. Overtreatment occurred, but the rate can be reduced with appropriate recommendations. HSIL Pap smears should be reexamined before S&T while low grade and lesser colposcopic impression groups should obtain conventional colposcopic approach for patient future reproductive benefit.

The role of surgical intervention in patients with diabetic gastroparesis is unclear. We report a case of a 37-year-old man with a history of recurrent episodes of vomiting and long-standing type 2 diabetes mellitus. Esophagogastroduodenoscopy did not reveal any findings of reflux esophagitis or obstructive lesions. A gastric emptying time scan showed prolonged gastric emptying half-time (344 minutes) indicating delayed gastric emptying. Laboratory tests revealed elevated fasting serum glucose and glycosylated hemoglobin (HbA1c, 12.9%) and normal fasting C-peptide and insulin levels. We performed Roux-en-Y reconstruction after subtotal gastrectomy to treat gastroparesis and improve glycemic control, and the patient showed complete resolution of gastrointestinal symptoms postoperatively. Barium swallow test and gastric emptying time scan performed at follow-up revealed regular progression of barium and normal gastric emptying. Three months postoperatively, his fasting serum glucose level was within normal limits without the administration of insulin or oral antidiabetic drugs with a reduced HbA1c level (6.9%). Long-limb Roux-en-Y reconstruction after subtotal gastrectomy may be useful to treat severe diabetic gastroparesis by improving gastric emptying and glycemic control.
