Neuropeptide Y and Stress

The neurobiological aspects of stress and coping skills has been the focus of interest for many researchers. Some of the studies has shown that there is a significant relationship among genetically variables, stress response and life events. Neuropeptide Y is one of the systems regulating the stress response. Under the prolonged or repeated trauma neuropeptide Y is released from the brain's key areas. This system shows different levels of functioning in individuals with different levels of resilience. There is particular interest in the variations of genes that encode stress-sensitive signaling molecules during gene-environment interaction. This condition may contribute to susceptibility of stress or stress resilience. Neuropeptide Y system plays a key role in the adaptation to behavioral stress. The reduced levels of neuropeptide Y have also been observed in treatment-resistant depression and posttraumatic stress disorder. Lower level of neuropeptide Y expression and dysfunctional neuropeptide Y system in response to stress and resulting decreased stress resilience could increase susceptibility to stress-related disorders

Plasma fibrinogen level may predict critical coronary artery stenosis in young adults with myocardial infarction

Background: This study aims to determine the role of hematological variables in determining critical coronary artery stenosis in young adults with myocardial infarction. Methods: This study includes 76 of 1,804 patients who applied to our hospital between January 2001 and December 2005. All were under 35 years old, diagnosed as acute myocardial infarction with clinical and laboratory findings, and had coronary angiography. Study patients were divided into two groups: those having critical coronary artery lesions (group I) and those having normal coronary arteries (group II). Then we compared these groups for age, sex, body mass index, risk factors, plasma protein C, protein S, antithrombine III and fibrinogen. Student t test, the c2 test, Fisher’s exact test and Mann Whitney U test were used. Results: There were no differences between the two groups in terms of hypertension (p = 0.70), smoking (p = 0.50), hyperlipidemia (p = 0.09), body mass index (p = 0.14), family history (p = 0.10), plasma protein C (p = 0.08), protein S (p = 0.35) or antithrombine III (p = 0.60). Plasma fibrinogen levels were significantly higher in group I than in group II (p = 0.001). Conclusions: Our study shows that high plasma fibrinogen levels may be used as a predictor of critical coronary artery lesions in young patients with acute myocardial infarction

Melatonin: General Features and its Role in Psychiatric Disorders

In recent years, there is a growing interest in melatonin all over the world. The main task of protecting the body's biological clock, which set the rhythm of melatonin, involves many biological and physiological processes of the body. Cell renewal, strengthening of the immune system and body temperature regulation are other tasks of melatonin. Melatonin, with its lipophilic property, is the most powerful antioxidant as it can reach all body areas and can easily pass the blood-brain barrier. The fact that individuals with low levels of melatonin have sleep problems lead to the consideration of melatonin as a therapeutic medicine in this field. The detailed researches have shown that melatonin can improve sleep quality without changing the total duration of sleep. Nevertheless, despite high number of researches done, the functions of melatonin have not yet fully understood. Therefore, review of the available information related to melatonin will be guide for researchers in the field

Advertisement scheduling in Bluetooth low energy devices

Bluetooth low energy (BLE) is a new communication protocol which is suitable for wireless devices that must operate with very low energy and/or harvesting ambient energy. In this paper, a novel technique, which provides efficient operation by adapting BLE protocol in accordance with consumable power limitations, is proposed. The essence of this technique lies in the observation that a considerable decrease in power comsumption can be achieved by lengthening advertisement intervals. The scheduling algortihm, which was developed as a result of problem formulation and analysis, maximizes advertisement throughput and minimizes the expected total waste of receiving attempts produced by near wireless receivers while setting advertisement intervals according to energy harvesting rates

A Multi-Flow Production Line for Sorting of Eggs Using Image Processing

In egg production facilities, the classification of eggs is carried out either manually or by using sophisticated systems such as load cells. However, there is a need for the classification of eggs to be carried out with faster and cheaper methods. In the agri-food industry, the use of image processing technology is continuously increasing due to the data processing speed and cost-effective solutions. In this study, an image processing approach was used to classify chicken eggs on an industrial roller conveyor line in real-time. A color camera was used to acquire images in an illumination cabinet on a motorized roller conveyor while eggs are moving on the movement halls. The system successfully operated for the grading of eggs in the industrial multi-flow production line in real-time. There were significant correlations among measured weights of the eggs after image processing. The coefficient of linear correlation (R2) between measured and actual weights was 0.95

Comparison of conservative and surgical treatment methods in patients with meniscopathy

Objective: Arthroscopic surgery is currently a well-known treatment method for meniscal pathologies. This study aims to compare conservative and surgical methods in patients with meniscopathy. Materials and Methods: The retrospective analyses of 68 patients with meniscal tear were included in this study. Patients were divided into two groups: a medical treatment group (MTG) and a surgical treatment group (STG). Diagnosis was perfomed by physical examination and magnetic resonance imaging (MRI). All patients were evaluated before and after treatment with main pain score (MPS), International Knee Documentation Committee (IKDC) score, body mass index (BMI), and Ultrasensitive C-reactive protein (US-CRP). In the MTG group, 31 patients underwent medical treatment with naproxen sodium for three days, ice application, activity modification, and muscle exercises. In the STG group, 37 patients underwent arthroscopic partial menisectomy and naproxen sodium for three days. Parameters characterizing pretreatment and posttreatment states were compared statistically. The MPS, IKDC, BMI, and US-CRP values of both groups were recorded at baseline and three months after treatment. Results: Surgical treatment group (STG): In this group, after three months of treatment, MPS decreased and IKDC scores increased significantly when compared with baseline (P < 0.0001 and P < 0.0001, respectively). The difference for the US-CRP levels and BMI values was not statistically significant (P = 0.1500 and P > 0.1799, respectively). Medical treatment group (MTG): In this group, MPS decreased and BMI increased significantly after three months compared with preoperative scores (P < 0.0001 and P < 0.0001, respectively). However, the difference between average IKDC scores and US-CRP levels was not statistically significant (P = 0.1828 and P > 0.05, respectively). Conclusion: IKDC and pain scores of patients with meniscal tear improved by arthroscopic knee surgery. [Arch Clin Exp Surg 2016; 5(2.000): 78-84

Evaluation of Patients Undergoing Removal of Glass Fragments From Injured Hands A Retrospective Study

WOS: 000292505600006PubMed ID: 21372675The hand is the body part most frequently injured by broken glass. Glass fragments lodged in soft tissues may result in numerous complications, such as infection, delayed healing, persistent pain, and late injury as a result of migration. Between 2005 and 2010, we removed 46 glass particles from the hands of 26 patients. The injuries were caused by the following: car windows broken during motor vehicle accidents in 11 patients (42%); fragments from broken glasses, dishes, or bottles in 9 (35%); the hand passing through glass in 5 (19%); and a fragment from a broken fluorescent lamp in 1 (4%) patient. Despite the efficacy of plain radiographs in detecting glass fragments, these are sometimes not obtained. Given the relatively low cost, accessibility, and efficacy of radiographs, and the adverse consequences of retained foreign bodies, the objections to obtaining radiographs should be few in diagnosing glass-related injuries of the hand
