The objective of this study was to produce particleboards for general purpose use by utilizing stalks of cotton grown in Turkey. Shortage of raw materials in the wood industry resulted in the search for new resources. This is also true for the particleboard industry. It is really necessary to find alternative sources of raw material in order to reduce deforestation. The goal of this study is to investigate the possible contribution to the economy by utilising the cotton stalks in the production of particleboards. It is concluded that the cotton stalks as a cheap raw material compared to woody sources can be used to produce the parti . . .cleboards that can meet with the required standards. Utilization of cotton stalks as a raw material does not only bring solution to the shortage of raw materials in the particleboard industry, but also allows a decrease in deforestation. In this study, water absorption, thickness swelling, bending strength internal bond properties of particleboards produced with cotton stalks at various resin addition levels and density ranges were studied. It was found that the particleboards produced at a 0.60-0.70 g/cm3 density range showed technological properties acceptable to the standards Daha fazlası Daha az

The aim of this study was to investigate the effects of different doses of iron on haematological status of breastfed infants. One hundred and thirteen infants were randomized into four groups at 5 months of age. Iron supplementation was given at doses of 1 mg/kg/day, 2 mg/kg/day, and 2 mg/kg/every other day in the first three study groups, respectively, and the last group received placebo. The hematological values, except hemoglobin, were higher in the group supplemented with iron at a dose of 2 mg/kg/day, and ferritin values were statistically higher in the group supplemented with iron at a dose of 2 mg/kg/every other day than in . . .the group supplemented with iron at a dose of 1 mg/kg/day. We suggest that intermittent iron supplementation is more effective than a daily regimen in equal dosages Daha fazlası Daha az

Purpose: To investigate whether restoration of normal stereo acuity is possible in refractive accommodative esotropia. Methods: Twenty patients with refractive accommodative esotropia were included in the study. The cycloplegic refraction and the best corrected visual acuity of each patient were recorded. The patients were evaluated by the 4-prism-diopter test, Bagolini striated glasses, the Worth 4-dot test, the TNO stereo test, and the stereo fly plate of the Titmus test. Results: Eight patients had orthotropia with normal retinal correspondence and 12 patients had a small deviation with abnormal retinal correspondence. Nine patie . . .nts (8 patients with orthotropia and 1 patient with microtropia) demonstrated a gross level of stereo acuity, whereas the others demonstrated no stereopsis. Conclusion: In patients with refractive accommodative esotropia, the prognosis is not favorable for restoration of normal stereopsis, even if orthotropia is achieved Daha fazlası Daha az

Bu çalışmada, karaağaç (Ulmus campestris Spach.) odunundan hazırlanan deney örneklerine % 25' lik konsantrasyondaki NaOH + H2O2 (I. çözelti) ve NaSiO3 + H2O2 (II. çözelti) grupları ile renk açma işlemi yapılmıştır. Renk açma işleminden sonra poliüretan ve poliester vernik uygulanan yüzeylerde renk açıcı kimyasal maddelerin kırmızı renk tonu oluşumuna etkileri ASTM-D 2244 esaslarına uyularak belirlenmiştir. Sonuç olarak, kırmızı renk tonu en yüksek poliüretan vernik uygulanan naturel örneklerde (19.94), en düşük I. grup (NaOH + H2O2) çözelti ve poliester vernik uygulanan örneklerde (4.26) elde edilmiştir. Buna göre; düşük kırmızı ren . . .k tonu istenen işlemlerde renk açma işleminden sonra odun yüzeylere poliüretan vernik uygulanmamalıdır. Son katta poliüretan vernik uygulanması söz konusu olduğunda, şeffaf renksiz dolgu verniği kullanılması kırmızı renk tonu oluşumunu azaltabilir. In this study, it has been performed the bleaching process with NaOH + H2O2 and NaSiO3 + H2O2 which have 25 % concentration elm wood of red color of tone measuring. It has been carried out to measure the red color of tone according to the procedure of ASTM-D 2244 standards. It has been done the bleaching process for red colour of tone effects on the wood surface covered with polyurethane and polyester varnish of some chemical materials. As a result, it has been obtained the highest red color of tone as naturel samples with polyurethane varnish (19.94), the lowest red color of tone as I. solution (NaOH + H2O2) and polyester (4.26). According to this, polyurethane varnish must not be applied to have bleached surfaces that wishing the less red color of tone of surfaces after the bleching process. If the transparent filler varnish is used, the red color of tone can be reduced, in case of the polyurethane apply on the wood surfaces as a last layer Daha fazlası Daha az

OBJECTIVE: To report a case of rhabdomyolysis possibly due to combination therapy with colchicine and gemfibrozil. CASE SUMMARY: A 40-year-old man with amyloidosis and hepatitis B virus-related chronic liver disease was admitted to the university hospital because of fatigue, lack of appetite, dark brownish urine, and myalgia for 2 weeks. The patient was receiving colchicine and gemfibrozil. Elevations of serum creatine kinase, lactate dehydrogenase, and aspartate aminotransferase concentrations with myalgia were compatible with the diagnosis of rhabdomyolysis. DISCUSSION: To our knowledge, myopathy and rhabdomyolysis due to a combin . . .ation of colchicine and gemfibrozil therapy have not been previously reported. Preexisting mild renal failure, hepatitis B-related chronic liver disease, and amyloidosis may be contributing risk factors for the development of rhabdomyolysis in this patient. An objective causality assessment revealed that the adverse drug event was possible. CONCLUSIONS: Patients receiving combination therapy with colchicine and gemfibrozil, especially those with renal and hepatic dysfunction, should be monitored for rhabdomyolysis, and concomitant colchicine and gemfibrozil therapy should be considered in the differential diagnosis of rhabdomyolysis Daha fazlası Daha az

BACKGROUND: The results of the eight patients who admitted to emergency room with tibial plateau fractures and treated with Ilizarov technique, were retrospective evaluated both clinically and radiologically. METHODS: Seven (87%) men and one (13%) woman ranging in age from 23 to 38, were evaluated. All the cases were between type IV to VI according to Hohl classification preoperatively. Closed indirect reduction by ligamentotaxis was attempted in all fractures, no open technique was performed. RESULTS: Three (38%) cases had open fractures (type I according to Gustilo-Andersen Classification) preoperatively. Six (75%) traffic acciden . . .t and two (25%) falling from a height were detected as etiology. The cases, whose average follow up was 14 (6-28) months, were evaluated according to Iowa knee score scale and seven (87%) cases were good and excellent. Both clinical and radiological solid fusion were obtained in all cases after removing the frame. Although all the cases had minimal to moderate pin tract infection, all were resolved with dressing and oral antibiotherapy without removing the wires. CONCLUSIONS: Closed reduction with Ilizarov technique is appropriate for treatment of plateau tibia fractures with minimal morbidity Daha fazlası Daha az
