The Roles of Mating, Age, and Diet in Starvation Resistance in Bactrocera oleae (Olive Fruit Fly).

The olive fruit fly (Bactrocera oleae (Rossi) (Diptera: Tephritidae)), although a pest of major economic importance for the olive industry, has not been sufficiently studied with respect to the factors affecting its survival resistance to food deprivation. In the present study, we examined the effect of the interaction between mating status (virgin/mated), age class (11-20/21-30/31-40/41-50), and diet quality (protein plus sugar or only sugar) on starvation resistance in B. oleae under constant laboratory conditions. We conducted a total of 16 treatments (2 × 4 × 2 = 16) for each gender. Our results showed that starvation resistance in B. oleae did not differ significantly between females and males. The main conclusions of our study regarding mating status, age, and diet indicated that mated adults showed much less starvation resistance compared to virgins, younger adults endured longer, and the adults fed a restricted diet endured longer than those fed a full diet. A three-way interaction between mating status, diet, and age class was also identified and was the same for both genders. The interaction between mating status, age class, and diet also had a significant influence on starvation resistance in both sexes.

Could energy equilibrium and greenhouse gas emissions in agroecosystems play a key role in crop replacement? A case study in orange and kiwi orchards.

The development of agriculture is linked to energy resources. Consequently, energy analysis in agroecosystems could be a useful tool for monitoring some measures in the agricultural sector to mitigate greenhouse gas emissions. The objectives of this study were to (a) evaluate differences of energy indices in orange and kiwi orchards, and (b) point out whether inputs, outputs, efficiency, productivity, and carbon footprint can play a key role in crop replacement. Proportional stratified random sampling was used to select 26 orchards (10 oranges, 16 kiwis) from the Prefecture of Arta, western Greece, during 2015 and 2016. Univariate statistical methods were combined with multivariate ones. Nitrogen, Mg, Zn, herbicides, insecticides, fungicides, renewable energy inputs, fruit production, total outputs, and energy efficiency and productivity were statistically significantly high in the orange orchards. Phosphorus, Ca, irrigation, machinery, total inputs, intensity, non-renewable energy consumption, and carbon footprint were statistically significantly high in the kiwi orchards. The most important energy inputs for both fruit crops were fertilizers, fuels, irrigation, machinery, and herbicides. The orange orchards seem to be more friendly to the environment than the kiwi orchards by having low total energy inputs 32,210.3 MJ ha-1, intensity 1.4, consumption of non-renewable energy 0.7 MJ kg-1 and CO2 equivalent/fruit production 0.08 kg kg-1, and high energy outputs 105,120.0 MJ ha-1 and fruit production 53,648.0 kg ha-1. The findings of the present study show a relation between climate change and the production of farming systems, which can be a tool for decision makers. The correlation of the abovementioned parameters ensure higher profits and could help in achieving the best possible sustainable management of the agricultural ecosystems.

Short-Term Impact of Non-Surgical and Surgical Periodontal Therapy on Oral Health-Related Quality of Life in a Greek Population-A Prospective Cohort Study.

While periodontitis deteriorates patients' quality of life, non-surgical periodontal treatment seems to offer an improvement. The purpose of the present study was to evaluate the impact of non-surgical and surgical periodontal treatment on the oral health-related quality of life (OHRQoL) utilizing patient-centered assessments and surrogate clinical measurements in Greek adults. Eighty-three individuals with chronic periodontitis were enrolled in the study. Assessment of OHRQoL with the use of the Oral Health Impact Profile (OHIP-14) questionnaire in conjunction with clinical measurements of pocket probing depth (PPD), plaque index (PI) and bleeding on probing (BOP) were performed at baseline (t0), after non-surgical therapy (t1) and after periodontal surgery (t2). A statistically significant reduction of OHIP-14 score was recorded at t1 and t2 examination compared to baseline (p < 0.001) and a statistically significant improvement in all clinical parameter at all time points was recorded (p < 0.05). No correlation between the clinical parameters and the total score of OHIP-14 was recorded at any time point. Non-surgical periodontal treatment seemed to improve OHRQoL in terms of OHIP-14 scores, whilst supplementary surgical periodontal therapy did not offer any additional benefit. No correlation was found between patients' perception of quality of life expressed by OHIP-14 score and the surrogate clinical parameters.

An efficient framework for conducting systematic literature reviews in agricultural sciences.

Systematic review has generally been accepted as an effective, more complete, repeatable, and less biased type literature review that can successfully lead to evidence-based conclusions. This study attempts to develop a framework for systematic review with guidelines on how to conduct an effective systematic review for agricultural research. Systematic reviews require more time and effort but they can be used to conduct a comprehensive literature review, identifying potentially eligible articles on primary agricultural research and answering certain focused questions. A systematic review is also conducted as an example to examine whether systematic reviews are used in agricultural sciences. It was found that in the last two decades about a third (N = 29 out of 89 or 32.5%) of the eligible studies, classified as reviews related to agricultural research, are available as free full-text from publisher, while only eighteen of them were finally eligible to be included in this systematic review.

A systematic review and meta-analysis of abdominal compartment syndrome after endovascular repair of ruptured abdominal aortic aneurysms.

OBJECTIVE: Limited data exist regarding the development of abdominal compartment syndrome (ACS) after endovascular repair of ruptured abdominal aortic aneurysms (RAAAs). We aimed to record the incidence, management, and outcome of this complication. METHODS: A systematic review and meta-analysis of the English language literature was undertaken through June 2012. Articles reporting data on outcome after endovascular repair of RAAAs were identified, and information regarding ACS was sought. RESULTS: Included were 39 eligible studies reporting 1134 patients. The pooled perioperative mortality was 21% (95% confidence interval [CI], 18%-24%). A total of 109 cases of ACS were recorded. There was significant within-study heterogeneity (Cochran Q = 94.1; P < .0001), and the pooled ACS rate was 8% (95% CI, 5.6%-10.8%). Only six studies accurately defined ACS, and four focused specifically on ACS. When the meta-analysis was repeated after including only studies with a definition and those focusing on ACS, the pooled rate increased to 17% (95% CI, 10%-26%) and 21% (95% CI, 13%-30%), respectively. A random-effects meta-regression analysis investigating the effect of ACS and other risk factors on mortality revealed a significant linear correlation between hemodynamic instability and death (r = 0.303) and a nonlinear (second degree polynomial) association between bifurcated endograft approach and death (R(2) = 0.348; P = .0027). However, no statistically significant association could be found between ACS and death. A further meta-regression analysis failed to identify any statistically significant predictors of ACS. Treatment included open decompression in 86 patients, percutaneous drainage in 18 (catheter only in five, combined with tissue plasminogen activator infusion in 13), and conservative measures in five. Data on outcome of ACS were only available for 76 patients; 35 of these died, for a mortality rate of 47%. CONCLUSIONS: The pooled ACS rate was calculated at 8%, but this figure may be >20% with improved awareness and vigilant monitoring. Although no statistically significant association could be found between ACS and death, almost half the patients who developed ACS after endovascular repair of RAAAs were likely to die.
