Turkish Journal of Medical Sciences

Plasma low density lipoprotein (LDL) had 3 subtypes according to its separation by polyacrylamide gradient gel electrophoresis. Of these, the small, dense (Sd) LDL particles have been accepted as an emerging cardiovascular risk factor. This study was conducted to assess the LDL subtypes in a group of patients undergoing coronary angiography. Materials and methods: The study involved 56 patients—36 of whom had at least 1 vessel stenosed (stenosis group)—and 20 patients who had no stenosis (non-stenosis group). LDL subtypes were determined according to their migration pattern after non-denaturing gradient gel electrophoresis. Total cholesterol, LDL and high density lipoprotein (HDL), and …

Turkish Journal of Medical Sciences

Hyperhomocysteinemia was induced in rabbits using methionine. Ocular blood flow changes were examined by color Doppler ultrasonography (CDU). Materials and methods: Fifty New Zealand rabbits were divided into 5 groups. Groups 1-4 received one of the following chemicals: methionine only, methionine plus vitamin B6, methionine plus vitamin B12, or methionine plus folic acid. Controls received no chemicals. Serum homocysteine levels were measured on treatment days 1 and 60. Orbital vessels were examined by CDU on day 60. Results: In the 4 study groups, homocysteine levels were significantly elevated on day 60 compared to the levels on day 1 (P < 0.05). Elevations of homocysteine levels in group 1 were greater than those of groups 2 and 4 on day 60 (P < 0.05). When results of ocular blood flow changes were compared, no statistically significant difference was found based on flow velocities in the ophthalmic artery. Measurements from the ciliary artery revealed a statistically significant decrease in flow velocity in the study groups (P < 0.05). Conclusion: Using CDU, we found that flow velocities in the ciliary artery were decreased. This condition is attributed to atherosclerotic and thromboembolic alterations of the ocular vessels due to hyperhomocysteinemia.

A Practical Calculation Method For Predetermination Of Amount And Duration Of Expander Application, Önder Tan Jan 2011

A Practical Calculation Method For Predetermination Of Amount And Duration Of Expander Application, Önder Tan

Turkish Journal of Medical Sciences

Expander application has become one of the methods most commonly used in reconstructive surgery by virtue of its many advantages. Determination of the amount and duration of expansion completely depends on a surgeon's experience and clinical estimation. Interestingly, no quantitative method has been described in the literature. In an attempt to address this issue, I developed a practical calculation method for expander cases. I use this technique daily during the expansion process to decide whether or not to complete the procedure. By means of this practical method, I believe that expanders can be optimally and more effectively utilized in reconstructive …

Materials and methods: We made various extracts of Um. These extracts in varying concentrations were added to an A549 NSCLC cell culture, alone or with gemcitabine and/or cisplatin. Growth inhibition was tested by the MTT assay and an Annexin V-FITC apoptosis detection kit Results: The onion Um extract (1 µg/mL) was more cytotoxic than cisplatin (1 µg/mL), gemcitabine (1 nm/mL), and leaf Um extract (1 µg/mL) with P < 0.001, P = 0.097, and P < 0.001, respectively. The efficacy of Um extract was further improved by the addition of an antioxidant cocktail to an IC_{50} value of 0.02 µg/mL. Conclusion: Um extract has been shown for the first time to be a strong candidate for drug development in solid tumors. Our studies continue to further define the specific antitumor compound(s) in this extract.

To investigate the effect of leptin treatment on circulating inflammatory cytokines and on tissue damage in experimental rat model of gram-negative sepsis. Materials and methods: Adult male Wistar rats, 28 in total, were randomly divided into 4 groups (n = 7): sham, leptin, sepsis, and sepsis group treated with leptin (sepsis+leptin). Sepsis was induced by intraperitoneal (ip) injection of 2 × 10^{10} CFU of Escherichia coli ATCC 25922. Leptin and sepsis+leptin groups received a single dose ip 0.1 mg/kg leptin, while sham group received 1 mL of ip saline. Rats were sacrificed 24 h after the induction of sepsis. Blood …

The purpose of this study was comparison of the glutamate dehydrogenase (gdh) and triose phosphate isomerase (tpi) genes for detection and genetic characterization of Giardia lamblia (G. lamblia) in human stool by polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (RFLP). Our assay was specific and distinguished between G. lamblia assemblages A and B. Materials and methods: Among the 325 stool samples obtained from patients with acute gastroenteritis hospitalized in the Pediatric Hospital and infected humans referred to the Tabriz Reference Laboratory (TRL), 34 Giardia-positive stool samples were identified by conventional techniques. Two assays-PCR and PCR-RFLP-targeting the tpi and …
