Effects of Occupational Health and Safety on Healthy Lifestyle Behaviors of Workers Employed in a Private Company in Turkey

Background: It has been suggested that inappropriate working conditions and unsafe environments at construction sites, longer working hours, and inadequate workplaces adversely affect the health behaviors of workers. Objective: The aim of this study was to evaluate the effect of occupational health and safety (OHS) practices on healthy lifestyle behaviors of workers employed at a construction site of a private company in Gaziantep, Turkey. Methods: The sampling size of this descriptive study consisted of 400 employees working at the construction site between December 2014 and January 2015. In all, 341 employees still working or participating in the study during the period of this questionnaire study were included in the sampling. Data from the survey were derived from responses to questions regarding sociodemographic characteristics, OHS applications, health state, and working conditions, as well as to the questions in on the Healthy Lifestyle Behaviors Scale (HLBS), under direct surveillance. Findings: Male workers with a mean age of 30.61 ± 8.68 years constituted the study population. Of the workers, 41.9% had a primary school education. The majority received professional and OHS training (65.7% and 79.2%, respectively). Although 83.9% reported using personal protective equipment (PPE), only 2.1% said they had experienced an occupational accident. Total mean score of HLBS scale was 116.91 ± 25.62 points. Workers who had positive thoughts about their jobs demonstrated healthy lifestyle behaviors ('P' = .0001). A positive direct correlation was detected between the training the workers received and the use of PPE ('P' = .0001). In all, 38.1% of the workers reported experiencing work stress at the time of the study. Mean HLBS scores of those experiencing work stress were lower than the scores for workers not experiencing stress ('P' < .05). Conclusion: Receiving OHS and professional training and using of PPE favorably affect healthy lifestyle behaviors

Antimicrobial activity of leaf extracts of Bituminaria sp. genotypes at different growth stages

302-309Plants have secondary metabolites that play a role in defense mechanism are known to have effects on microorganisms. These metabolites and their amounts vary depending upon various factors. Here, we studied the antimicrobial effect of secondary metabolites of Bituminaria sp. genotypes and explored whether this effect changes with different growing stages of the plant. The results show that extracts obtained from 12 B. bituminosa genotypes were not significantly effective on Gram-negative bacteria but highly effective on Gram-positive bacteria and eukaryotic yeast. Of these genotypes, 9 and 12 genotype were more effective than the rest. Observations suggest that the extracts from the plants are more effective during the beginning of flowering stage than the growth and budding stages for the bacteria studied. It could be due to the differences in the nature of the metabolites and their quantity

Mineral contents of chickpea cultivars (Cicer arietinum L.) grown at different locations of Turkey

Mineral deficiency-induced diseases and health problems influence billions of people worldwide. Development of edible legumes with high mineral contents will provide significant contributions in reducing the frequency of such diseases. Among the edible legumes, chickpea has quite high nutritional values and quite low production costs, thus commonly grown and consumed worldwide. This study was conducted to determine mineral (potassium, phosphorus, sulphur, calcium, magnesium, sodium, zinc, iron, boron, manganese, copper) contents of eight different chickpea cultivars (Akçin-91, Azkan, Hisar, Akça, Gökçe, Yaşa-05, Işık-05 and Çakır) grown in two different locations (Afyonkarahisar and Yozgat provinces of Turkey) for two years (2015 and 2016). Experiments were conducted in randomized blocks design with three replications. Among the minerals, potassium was highest (6435.2-8231.7 mg kg-) followed by phosphorus (2573.9-3094.0 mg kg-1) and sulphur (1710.9-2060.7 mg kg-1). Among the minerals, copper was lowest followed by boron and manganese. Considering the average of locations, it was observed that Gökçe, Akçin-91, Azkan and Hisar cultivars were prominent with sulphur content; Akça with boron, sodium and calcium contents; Yaşa-05 and Işık-05 with potassium, phosphorus, magnesium, zinc, iron, magnesium, manganese and copper contents. Çakır cultivar was stable for all minerals. The concentrations of seed P, S, Ca, Mg, B and Mn were significantly affected by locations

Ankaferd Hemostat' In Mcf-7 Meme Kanseri Hücre Hattına Etkisinin Proteomik Analizlerle İncelenmesi

Nowadays, a large number of cancer-related research is being conducted, which is one of the most difficult and deadly diseases to treat. Thanks to one of these studies, proteomics analysis, which is one of the omic techniques, cancer can be examined at the protein level and shed light on new alternatives as well as supporting current clinical studies related to the mechanism of diagnosis, treatment and diagnosis of cancer. In this study, after the MCF-7 breast cancer cell line was treated with Ankaferd Hemostat (ABS; Ankaferd Blood Stopper®) for different periods of time, comparative proteomic studies performed on ABS untreated (control, C group) and ABS treated cells (treated, T group). Thus, the effect of ABS was examined at molecular level after being applied in vitro on MCF-7 breast cancer cell line. In this study, proteins belonging to C and T groups were separated by two-dimensional gel electrophoresis. After ABS were applied, decreasing or increasing amounts of proteins were determined by image analysis studies. As a result of comparison of C and T groups, proteins which were Quantitatively differentiated at least 2-fold were analyzed by matrix assisted laser desorption/ionization, flight time mass spectrometry (MALDI-TOF/TOF-MS) and identified by peptide sequencing studies. The identified proteins were searched with the help of databases and their functions and protein-protein interactions were determined. The biological processes and pathways that ABS has affected on MCF-7 breast cancer cell have been identified with the database of String and KEGG. The obtained proteins were associated with the studies in the literature in order to explain the anticancer activity of ABS at the proteome level.Günümüzde tedavisi en zor olan ve ölümcül hastalıkların başında gelen kanserle ilgili çok sayıda araştırma gerçekleştirilmektedir.
