    In insects, cuticular hydrocarbon (CHC) profile is involved in many important biological functions and may vary in different conditions. Among fruit fly species, Drosophila subobscura is one of the most frequently used in genetic, ecological and evolutionary research, because of its rich chromosomal polymorphism, specific behavioral repertoires and habitat preferences. In this work, we identified and quantified cuticular chemoprofile of D. subobscura. Using gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS), 25 chemical compounds were found in males and 23 compounds were found in females. Further, ANOVA confirmed significant sexual dimorphism in cuticular chemoprofile amounts. Knowledge of cuticular chemistry could contribute to further research in D. subobscura, starting from behavioral, up to ecological, since this species is recognized as an important model system for the study and monitoring of global climate changes. © 2018, Pakistan Agricultural Scientists Forum.

    The politics of performance: transnationalism and its limits in former Yugoslav popular music, 1999–2004

    Get PDF
    This paper examines transnational relations between the Yugoslav successor states from the point of view of popular music, and demonstrates how transnational musical figures (such as Djordje Balaševi?, Mom?ilo Bajagi?-Bajaga and Ceca Ražnatovi?) are interpreted as symbolic reference points in national ethnopolitical discourse in the process of identity construction. Another symbolic function is served by Serbian turbofolk artists, who in Croatia serve as a cultural resource to distance oneself from a musical genre associated by many urban Croats with the ruralization (and Herzegovinization) of Croatian city space. In addition, value judgements associated with both Serbian and Croatian newly composed folk music provide an insight into the transnational negotiation of conflicting identities in the ex-Yugoslav context. Ultimately the paper shows how the ethnonational boundaries established by nationalizing ideologies created separate cultural spaces which themselves have been transnationalized after Yugoslavia's disintegration

    Structured headache services as the solution to the ill-health burden of headache: 1. Rationale and description

    Get PDF
    In countries where headache services exist at all, their focus is usually on specialist (tertiary) care. This is clinically and economically inappropriate: most headache disorders can effectively and more efficiently (and at lower cost) be treated in educationally supported primary care. At the same time, compartmentalizing divisions between primary, secondary and tertiary care in many health-care systems create multiple inefficiencies, confronting patients attempting to navigate these levels (the “patient journey”) with perplexing obstacles. High demand for headache care, estimated here in a needs-assessment exercise, is the biggest of the challenges to reform. It is also the principal reason why reform is necessary. The structured headache services model presented here by experts from all world regions on behalf of the Global Campaign against Headache is the suggested health-care solution to headache. It develops and refines previous proposals, responding to the challenge of high demand by basing headache services in primary care, with two supporting arguments. First, only primary care can deliver headache services equitably to the large numbers of people needing it. Second, with educational supports, they can do so effectively to most of these people. The model calls for vertical integration between care levels (primary, secondary and tertiary), and protection of the more advanced levels for the minority of patients who need them. At the same time, it is amenable to horizontal integration with other care services. It is adaptable according to the broader national or regional health services in which headache services should be embedded. It is, according to evidence and argument presented, an efficient and cost-effective model, but these are claims to be tested in formal economic analyses

    Among the many antibiotics that treat infections of the respiratory system, the most common and with a large role are penicillins, cephalosporins, and macrolides. Acute otitis media is rapidly formed otitis media, with the duration of the inflammatory process to 3 weeks. As a rule, there is a nasal-pharyngeal route, and causes are viruses, bacteria and / or a viral / bacterial coinfection. To determine the effectiveness of amoxicillin, amoxicillin with clavulanate, ceftriaxone and azithromycin in children aged 0 to 14 years, depending on the number of repeat episodes. 120 patients with acute inflammation of the middle ear, treated in the cabinet of Otorhinolaryngology of Health Center of Gracanica. Diagnosis of the patients was placed and confirmed on the basis of physical examination, laboratory and microbiological analysis and tympanometry findings. 120 children aged 0-14 years. 52 (43.33%) male and 68 (56.67%) female. In 37 (30.83%) an episode of OMA, in 41 (34.86%) two episodes, in 29 (24.16%) three, in 13 (10.83%) cases more than three episodes in the past year. In 23 (19.16%) two epizide acute inflammation shorter than two months, in 11 (9.16%) children 3 episodes in 6 months, and in 13 (10.83%) children four episodes OMA for a period of one year . Causes: Streptococcus pneumoniae (37.64%), Haemophilus inphluenzae (14.11%), Moraxella catarrhalis (12.94%) and Pseudomonas (12.94%), Staphylococcus aureus (4.70%), Escherichia coli (4.70%) and Streptococcus pyogenes (3.52%). Amoxicillin (90 mg / kg bw) and amoxicillin + clavulanate (90 mg / kg bw), azithromycin (5-10 mg / kg bw), ceftriaxone (50mg / kg). Based on our research, we came to the data that is generally consistent with the WHO recommendations for the treatment of OMA in children

    Properties of wool textile products are partly governed by morphological composition and chemical structure of the surface of wool fibre. Both chemical structure and morphological composition are most frequently changed by some chemical treatments aimed to achieve specific effects (anti-felting effect, handle improvement, increased wettability, improved dyeing or printing ability etc.). Enzymatic treatment is now frequently used in order to achieve specific effects on wool surface because of lower environmental impact, especially if it is compared with conventional chemical agents (e.g. sodium salt of dichloroisocyanuric acid, NaDCC). Assessment of quantitative and qualitative changes of wool fibre is of particular importance for the right choice and optimisation of process parameters. In the present work, the changes of wool structure after enzymatic treatment are confirmed by SEM microscopy, FTIR/ATR spectrometry and corresponding physico-chemical methods (urea-bisulphite solubility. alkaline solubility, wetting time, weight loss and Herbig's reaction). The efficiency of the wool enzymatic treatment was compared with the efficiency of NaDCC treatment

    Abstract. Floating islands represent residue of peat which swam out on surface of water after flooding former Vlasina peat-bog. These islands are refuges of plant and animal species characteristic from peat-bog habitats. These specific habitats destroyed to a great extent with exploitation of peat for different human needs and survival of many plant and animal species endangered

    Soccer vs. running training effects in young adult men: which programme is more effective in improvement of body composition? Randomized controlled trial

    The aims of this study were: 1) To determine the effects of a 12-week recreational soccer training programme and continuous endurance running on body composition of young adult men and 2) to determine which of these two programmes was more effective concerning body composition. Sixty-four participants completed the randomized controlled trial and were randomly assigned to one of three groups: a soccer training group (SOC; n=20), a running group (RUN; n=21) or a control group performing no physical training (CON; n=23). Training programmes for SOC and RUN lasted 12-week with 3 training sessions per week. Soccer sessions consisted of 60 min ordinary five-a-side, six-a-side or seven-a-side matches on a 30-45 m wide and 45-60 m long plastic grass pitch. Running sessions consisted of 60 min of continuous moderate intensity running at the same average heart rate as in SOC (~80% HRmax). All participants, regardless of group assignment, were tested for each of the following dependent variables: body weight, body height, body mass index, percent body fat, body fat mass, fat-free mass and total body water. In the SOC and RUN groups there was a significant decrease (p<0.05) in body composition parameters from pre- to post-training values for all measures with the exception of fat-free mass and total body water. Body mass index, percent body fat and body fat mass did not differ between groups at baseline, but by week 12 were significantly lower (p<0.05) in the SOC and RUN groups compared to CON. To conclude, recreational soccer training provides at least the same changes in body composition parameters as continuous running in young adult men when the training intensity is well matched
