Research on endangered British butterflies has found that butterfly populations in small refuges evolve to allocate more mass to the thorax (flight muscle) and less to the abdomen than populations in large refuges. The observed change in mass allocation affects two morphological features relevant to flight: the flight muscle ratio (FMR) and the position of center of body mass (cmbody). The author tested whether a decrease in FMR or a change in cmbody reduced the ability to disperse by experimentally weight-loading Neotropical Anartia fatima butterflies. In one treatment group, FMR was decreased but cmbody was not altered, whereas in the second group FMR was decreased and cmbody was repositioned further posterior. In one mark–release–recapture (MRR) experiment, butterflies dispersed relatively slowly, and treatment groups did not differ significantly. In a replicate experiment, butterflies dispersed more quickly, and control butterflies dispersed more rapidly than either treatment group. Differences in dispersal were consistent with a causal relationship between FMR and movement. A more posterior cmbody had little effect on dispersal beyond that due to the change in FMR. These results support the hypothesis that an increase in mass allocation to the thorax in small, dispersed refugia is due to selection on the ability to disperse.

Randomized controlled trials of the effects of the dietary supplement Efacal® (Scotia Pharmaceuticals Plc, Guildford, Surrey, UK) v. Ca only on total body bone mineral density (BMD) and markers of bone turnover were conducted in healthy pre- and postmenopausal women separately. Total daily dose for 12 months for the Efacal® groups was: Ca 1·0 g, evening primrose oil 4·0 g and marine fish oil 440 mg; and for the control groups was: Ca 1·0 g. Reported compliance was better than 90 % in both age groups. For the forty-three premenopausal women (age range 25–40 years), initial mean total body BMD values were similar for Efacal® and control groups and both groups showed highly significant mean increases of about 1 %; however, there were no significant between-group differences for the changes in BMD or markers of bone turnover. For the forty-two postmenopausal women (age range 50–65 years), initial mean total body BMD values were again well-matched across treatment groups. Both Efacal® and control groups showed highly significant decreases in total body BMD of about 1 %, but again there were no significant between-group differences in total body BMD or markers of bone turnover. Possible confounding variables such as initial total body BMD were explored but had no effect on the outcome in either age group. Nail quality improved in both age groups and in both Efacal® and control groups. Again, there was no significant difference between treatment groups. No evidence was found to support a beneficial effect of Efacal® on BMD in these women.

The high losses in shrimp production due to mortality caused by Vibrio opportunistic pathogens still constitute a significant challenge in the shrimp industry. Synbiotic feed supplementation appears to be a promising control strategy to maintain healthy shrimp stock. In this study, the effects of synbiotic-containing prebiotic seaweeds Kappaphycus alvarezii and Spirulina sp. as well as probiotic Halomonas alkaliphila were evaluated on the survival, growth, and vibriosis of Litopenaeus vannamei during the post-larval stage. Five different feeds were tested: commercial feed, prebiotics K. alvarezii and Spirulina sp.-supplemented feed, and synbiotic-supplemented feed using K. alvarezii, Spirulina sp. and probiotic H. alkaliphila with different concentrations of 108, 109, and 1010 CFU.kg−1. Following 14 days after the feeding test, the highest shrimp survival (91.46 ± 0.05%) was obtained in the treatment group fed with synbiotic-supplemented feed containing 0.375% K. alvarezii, 0.125% Spirulina sp., and H. alkaliphila at 109 CFU.kg−1 (p < 0.05). A 7-day challenge test against opportunistic bacteria Vibrio harveyii was then performed using three treatment groups: (1) synbiotic, containing 0.375% K. alvarezii, 0.125% Spirulina sp., and H. alkaliphila at 109 CFU.kg−1; (2) prebiotic, with 0.375% K. alvarezii, 0.125% Spirulina sp.; and (3) control, using commercial feed. The highest shrimp survival of (79.9 ± 0.05%) was found in the synbiotic treatment group, followed by the prebiotic and control treatment groups (p < 0.05). Overall results suggested that synbiotic-supplemented feed containing 0.375% K. alvarezii, 0.125% Spirulina sp., and H. alkaliphila at 109 CFU.kg−1 significantly improved shrimp survival even when challenged with V. harveyii. Thus, this synbiotic can be potentially applied as an alternative biocontrol strategy against vibriosis in intensive shrimp post-larval culture.

Backgrounds: Asthma is a chronic airway inflammation which is a manifestation of complex interactions between cells and moleculer mediators. The aims asthma management is to reach asthma in controlled state. Providing an additional therapy in these circumstances is necessary to control asthma. Quercetin as an adjunctive therapy in asthma therapy may improve clinical symptoms and lung function. Methods: Experimental clinical trials of pretest of and postest design were conducted on 34 patient’s asthma at Dr. Moewardi Hospital Surakarta in 6 October–10 December 2018. Subject of treatment group (n= 17) was given quercetin 500 mg per day within 28 days, the control group (n=17) received only standar therapy asthma. Decreased airway inflammation was assessed based on the percentage of blood eosinophil and IL-5. Clinical improvement was assessed by ACT score while lung function used FEV1. Results: Quercetin decreased the inflammatory airways in patients with asthma evidenced by significant decrease in plasma IL-5 of treatment groups but no significant differences between treatment and control group, the mean decrease of blood eosinophil in the treatment group was significant. Querectin improved lung function with decrease FEV1 of treatment groups but no significant differences between treatment and control group and there was a clinical improvement with significant ACT score enhancement in the treatment group. Conclusion: The administration of quercetin significantly reduced inflammation based on decreased levels of eosinophils. There are improvement of lung function and clinical symptoms after quercetin.

Abstract The efficacy of flumethrin 1% pour-on (1% w/v, Flumitas) was evaluated against Haematobia exigua on cattle farms in Namakkal district, Tamil Nadu from November 2019 to February 2020. In this study, five farms, which had fly menace, selected randomly were divided as treatment (F1, F2, F3 and F4) and control (Fc) groups. Flies collected from the farms were identified as Haematobia exigua and a mean pre-treatment intensity was 195.56 ± 14.07. In the treatment groups (F1,F2,F3 and F4) flumethrin 1% pour on was applied to the back of cattle at the rate of 1 ml/10 kg body weight and fly intensity was recorded for a period of 2 months. The fly intensity reduced to zero within 30 minutes of application and the same trend continued till 28 DPT in F2 and F3, while it was effective 35 DPT in F1 and F4. A highly significant difference in the mean H. exigua fly counts between control and treatment group (P < 0.0001) was observed.

We developed a metabolomic method to evaluate the effect of pirfenidone on rats with acute paraquat (PQ) poisoning, through the analysis of various tissues (lung, liver, kidney, and heart), by gas chromatography–mass spectrometry (GC-MS). Thirty-eight rats were randomly divided into a control group, an acute PQ (20 mg kg−1) poisoning group, a pirfenidone (20 mg kg−1) treatment group, and a pirfenidone (40 mg kg−1) treatment group. Partial least squares-discriminate analysis (PLS-DA) revealed metabolic alterations in rat tissue samples from the two pirfenidone treatment groups after acute PQ poisoning. The PLS-DA 3D score chart showed that the rats in the acute PQ poisoning group were clearly distinguished from the rats in the control group. Also, the two pirfenidone treatment groups were distinguished from the acute PQ poisoning group and control group. Additionally, the pirfenidone (40 mg kg−1) treatment group was separated farther than the pirfenidone (20 mg kg−1) treatment group from the acute PQ poisoning group. Evaluation of the pathological changes in the rat tissues revealed that treatment with pirfenidone appeared to decrease pulmonary fibrosis in the acute PQ poisoning rats. The results indicate that pirfenidone induced beneficial metabolic alterations in the tissues of rats with acute PQ poisoning. Rats with acute PQ poisoning exhibited a certain reduction in biochemical indicators after treatment with pirfenidone, indicating that pirfenidone could protect liver and kidney function. Accordingly, the developed metabolomic approach proved to be useful to elucidate the effect of pirfenidone in rats of acute PQ poisoning.

Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), has become a key pest for soft fruits and cherries in Europe in less than a decade since the first outbreak in 2007. Although this pest’s passive dispersal ability has been observed over more than 1400 km in 1 year, active spread has not yet been extensively studied. A mark−release−recapture (MRR) method based on protein-marked flies was employed to determine the flight capacity of D. suzukii. Sterile marked flies were released and recaptured in a trap grid at increasing distances from 10 to 250 m from the releasing point to study flight distance during periods ranging from 3 h to 1 week. MRR experiments were replicated in the presence and absence of host fruits to study how they could affect dispersal behavior. The dispersal capacity of the Mediterranean fruit fly, Ceratitis capitata Wiedemann (Diptera: Tephritidae) was also studied under the same conditions. The results showed a low dispersal ability for D. suzukii, with a daily flight distance below 100 m with no predominant wind. The implications on natural dispersion and control methods based on attractants are discussed.

Climate change is causing widespread concerns along the coast, reducing agricultural productivity and destroying livelihoods. A study was conducted in two cyclone-prone districts of Bangladesh, Khulna and Satkhira, with a focus on women, to improve the climate-resilient livelihoods of coastal communities. Participatory rural appraisal techniques were used to collect community perceptions of climate change and variability, as well as adaptation options. A total of 699 participants were involved, where 466 respondents were in the treatment group mostly vulnerable to climate change, and 233 were in the control group similarly matched to the treatment groups. Female respondents were adequately involved in this research and accounted for 63% of the treatment and 60% of the control areas. Climate change was impulsive, according to the findings, and variability has increased over time with no optimistic outlook. The women had an idea about climate change, with 62.7% in the treatment group and 58% in the control group being aware of it. About 55.3% in treatment and 45% in control were willing to take preventative measures against climate change. Natural disasters and difficulty in selling their products impacted agricultural harvests, and as a result, both the treatment and control groups attempted to adapt to the alternative livelihoods in response to climate change. Respondents cited changes in rainfall patterns, cyclones, saline water intrusion, and other factors as causing lower yields and crop damage. To improve the adaptive capacities of their climate-resilient livelihoods, communities adapted to the changing environment by accepting high-yielding salt-tolerant varieties, introducing new technologies, and modifying livelihood options.

BACKGROUND: Post-partum physiological bleeding can cause post-partum mothers to experience anemia; often, post-partum mothers are limited by nutrient and fluid intake to keep the body strong and have ideal body weight. AIM: The aim of the study is to knowing the difference between beet juice and Guava juice on erythrocyte and hematocrit (HTC) levels in post-partum mothers at Darul Imarah Health Center, Darul Imarah District, Aceh Besar District. METHODS: This was a quasi-experimental study with a pre-post test design using a randomized controlled trial. The population of post-partum mothers in the Darul Imarah Health Center, Darul Imarah District, Aceh Besar District. The sample selection is purposive sampling with inclusion and exclusion criteria; the sample is 45 people. RESULTS: The results showed differences in erythrocyte and HTC levels between before and after giving guava and iron (Fe) juices with a p-value of 0.00 <0.05. Beet juice increases the average erythrocytes and HTC levels higher than guava juice. There were significant differences in erythrocyte levels in the guava + Fe, beet + Fe, and control (Fe) treatment groups with a p-value of 0.001 <0.05. the difference in the average difference in erythrocyte levels between the guava and beet treatment groups was 0.03. The treatment group Bit + Fe had a higher mean erythrocyte level different than the guava + the treatment group and the control group (Fe). There was a significant difference in HTC levels in the guava + Fe, beet + Fe, and control (Fe) treatment groups with a p-value of 0.001 <0.05. the difference in the average difference in erythrocyte levels between the guava and beet treatment groups was 0.03. The treatment group Bit + Fe had a higher mean difference in HTC levels than the guava + the treatment group and the control group (Fe). CONCLUSION: There is a significant difference in erythrocytes and HTC levels between before and after giving guava juice and beet juice to post-partum mothers with a p-value of 0.00 <0.05. Beet juice increases the average level of erythrocytes and HTC, which is higher than guava juice in post-partum mothers at the Darul Imarah Health Center.

When assignment to treatment group is made solely on the basis of the value of a covariate, X, effort should be concentrated on estimating the conditional expectations of the dependent variable Y given X in the treatment and control groups. One then averages the difference between these conditional expectations over the distribution of X in the relevant population. There is no need for concern about “other” sources of bias, e.g., unreliability of X, unmeasured background variables. If the conditional expectations are parallel and linear, the proper regression adjustment is the simple covariance adjustment. However, since the quality of the resulting estimates may be sensitive to the adequacy of the underlying model, it is wise to search for nonparallelism and nonlinearity in these conditional expectations. Blocking on the values of X is also appropriate, although the quality of the resulting estimates may be sensitive to the coarseness of the blocking employed. In order for these techniques to be useful in practice, there must be either substantial overlap in the distribution of X in the treatment groups or strong prior information.

Father’s role strongly proved in increasing the success of breastfeeding process, but in realitymany fathers are still not implementing its role in the process of breastfeeding (breastfeeding father’srole) because of father’s education and the assumption of breastfeeding is mother’s responsibilities. Thepurpose of this study was to analyze the effect of the father prenatal education toward breastfeedingfather’s role. This study used post test only control group design. 30 samples were taken by purposivesampling which further divided into control and treatment groups by simple random. Breastfeedingfather’s role was measured by a questionnaire and the data were analyzed by independent t test. Theresults showed breastfeeding father’s role rate and standard deviation in the treatment group was 15.40± 2.558, while in the control group 9.80 ± 4.212. Different test treatment and control group obtained thevalue p = 0,000 which means there was a significant effect of education toward breastfeeding father’srole between the treatment group and the control group. The nurse recommended to educate pregnantwomen prenatal classes which was devoted to the father (husband) as an alternative solution to improvethe success of exclusive breastfeeding program.
