Viral hepatitides are considered a major health problem worldwide. There are only a few studies relevant to the epidemiology of these types of infection in the normal healthy population. In this ...study, we aimed to determine the seroprevalence of hepatitis B and hepatitis C as well as the frequency of isolated anti-HBc IgG positivity among a normal healthy population in a northern province of Turkey.
This study was conducted in 70 areas (12 urban and 58 rural) in the province of Tokat, which is in the Black Sea region of Turkey, with about 530,000 inhabitants 18 years and older. All urban regions and some rural regions selected by a cluster sampling method were included in the study. The study population of 1,095 subjects (541 male and 554 female; urban 555 and rural 540) was selected by a random sampling method among 530,000 individuals. All individuals were tested for HBsAg, anti- HBs, anti-HBc IgG, anti-HCV, and alanine aminotransferase.
The mean age of all participants was 41.4+/-17 years (range, 18-95). HBsAg, anti-HBs, anti-HBc IgG only, isole and anti-HCV were detected in 60 (5.5%), 250 (22.8%), 132 (12.1%), and 23 (2.1%) individuals of the 1,095 total participants, respectively. We did not find statistically significant differences between hepatitis B and C markers for men versus women or those living in rural versus urban areas. The rate of HBsAg positivity in individuals with a history of marriage to close relatives was higher.
We found that the seroprevalences of hepatitis B and C in a northern province of Turkey are similar to the averages reported in other studies that were conducted in a different region of our country. The history of marriage to close relatives was associated with hepatitis B.
Our purpose was to investigate the effects of ischemia-reperfusion injury on traumatized lungs.
Twenty-four Wistar rats were used in the study. Rats were randomly divided into 4 groups. In the ...control group (group 1), only anesthesia and ventilation were used. In group 2, only lung ischemia-reperfusion injury was instituted. In group 3, only blunt chest trauma was instituted. And in group 4, lung ischemia reperfusion injury, consisting of 24 hours after the constitution of blunt chest trauma, was used. Lung damage and systemic inflammation parameters were evaluated.
All parameters (alveolar degeneration grades, alveolar macrophage and lymphocyte counts, antioxidant enzyme activities, cytokine levels, and bronchoalveolar lavage fluid albumin level) were higher in all groups than they were in the control group (P < .05). Only tissue malondialdehyde, tissue interleukin-8, and serum glutathione peroxidase levels were significantly higher in the lung ischemia-reperfusion group than they were in the trauma group (P < .05). The trauma + ischemia reperfusion group showed no significant difference when compared with the only ischemia-reperfusion or only trauma groups in any parameters (P > .05).
The findings showed that lung trauma does not aggravate the deleterious effects of lung ischemia-reperfusion injury.
BACKGROUND AND OBJECTIVEWe studied the long-term efficacy of pulsed radiofrequency treatment (PRF) on the saphenous nerve in 115 patients with chronic knee pain.MATERIALS AND METHODS115 patients with ...chronic knee pain were investigated in a period of 22~months retrospectively. All patients had pulsed radiofrequency to the saphenous nerve. The mean age was 59 (range, 51-67). All patients were accessed with the visual analog scale (VAS) and WOMAC score pain at rest, pain on movement, and pain in flexion at 10th day, 3rd and 6th~months post procedure.RESULTSAll patients showed improvement in their VAS scores as well as in their WOMAC scores after ten day, three month, and 6 months (p=0.001). No side effects were reported.CONCLUSIONPRF application to the saphenous nerve for eight minutes showed remarkable amount of patient satisfaction. Application of PRF for the second time could be recommended if it shows some benefit after the sixth month. But none of our patients needed a second application of PRF after six months period.
In recent years, the studies on the roles of caffeic acid phenethyl ester (CAPE) in several disease models and cell cultures are tremendously growing. It is such a great molecule that was used by ...ancient times to ameliorate some diseases and nowadays, it is used by modern medicine to test the effectiveness. In this mini-review article, the protection capability of CAPE, as a liposoluble antioxidant and a potent nuclear factor kappa B inhibitor, on oxidative and non-oxidative ovary, and testis damages has been summarized. In view of our laboratory findings/experience and those reported in the hitherto literature, we suggest that CAPE possesses protective effects for pathologies of the reproductive organs induced by untoward effects of harmful molecules such as free oxygen radicals, pesticides, methotrexate, and MK-801 (dizocilpine).
The cosine similarity measure is widely used in big data analysis to compare vectors. In this article a new set of vector similarity measures are proposed. New vector similarity measures are based on ...a multiplication-free operator which requires only additions and sign operations. A vector `product' using the multiplication-free operator is also defined. The new vector product induces the ℓ1-norm. As a result, new cosine measure-like similarity measures are normalized by the ℓ1-norms of the vectors. They can be computed using the MapReduce framework. Simulation examples are presented.
Designing a CAN BUS based measurement system for forklift simulator Aydogmus, Huseyin Ulvi; Akbas, Ahmet; Delibasoglu, Ibrahim
2013 The International Conference on Technological Advances in Electrical, Electronics and Computer Engineering (TAEECE)
Conference Proceeding
In this study, CAN-Bus based measurement system has been designed for forklift simulator. A Simple CAN-Bus network with multiple nodes has been modelled by software simulator for testing the CAN ...frame timing parameters. Two types of CAN based MCU modules have been designed according to their functions to provide the system scalability and portability. Embedded software for CAN based modules is designed to transmit CAN messages periodically with the same periods that tested in the software simulator. The real hardware units of forklift such as steering mechanism, pedals, levers, gear, gauges, switches have been modified with sensors and connected to the CAN based digital and analog input/output modules. Test results have shown that the CAN network communication with designed CAN based analog and digital input/output modules is stable for forklift simulator, achieved the goal of this design.
Aim: Neurotoxicity is the next common side effect of cisplatin
(CDDP)-based chemotherapeutics following nephrotoxicity. We
investigated the effect of CDDP on some brain metabolic enzyme
activities ...such as hexokinase (HK), glucose-6-phosphate dehydrogenase
(G6PD), lactate dehydrogenase (LDH), and malate dehydrogenase (MDH) in
an experimental model of CDDP toxicity, and examined the protective
role of Caffeic acid phenethyl ester (CAPE), a phenolic antioxidant
derived from the honeybee propolis, on the enzyme activities mentioned
above. Methods: Female Wistar albino rats were divided into three
groups: sham operation group (n:6), CDDP group (n:9), and CAPE + CDDP
group (n:8). All the chemicals used were applied intraperitoneally. HK,
G6PD, LDH, and MDH activities were determined spectrophotometrically in
the brain supernatant at the end of the surgical procedures. Results:
There were decreased G6PD activities and increased MDH activities in
CDDP group compared to control group (p<0.05, p<0.05). LDH
activities were increased in CAPE+CDDP group compared to CDDP group
(p<0.001). Conclusion: These results provide a new point of view on
the glucose metabolizing enzymes of brain tissue affected from CDDP and
the protective effects of CAPE on these enzymes.
