The study investigated the difference in performance of termiticides using concrete slab test installed in open field and under roof overhang.  Soil treated with cypermethrin and chlorpyrifos under roof overhang showed lower percentage of termite penetration compared to those in open field in each year of evaluation.  However, in both conditions termites were already able to penetrate treated plots during the first year of trial.  The high percentage of plots attacked by termites could be attributed to several environmental factors such as presence of a wider diversity of termite species, moisture, temperature, soil properties, microbial communities, etc. common in tropical climates.  The results from these two modes of installation could affect protocol used for field trial and the granting of registration or performance warranty to candidate termiticides in tropical countries.

Vegetative grafting has been proposed as a technique for managing diseases in tomatoes under open-field conditions. Over 2 successive years, we investigated the use of grafting under open-field fresh tomato production and found a serious limitation with current grafting techniques, which resulted in recurring rootstock shoot regrowth (“suckering”) from the rootstock cotyledons when left intact. Left unchecked, the regrowth of tomato rootstocks can envelop the experimental scions, which can impact the growth of field-grown tomatoes. In the Fall of 2007, the cultivars Multifort, Aloha, and TX-301 with ‘FL-47’ scions were grafted by a commercial propagator. These grafted plants were planted in a field experiment and after a time period, the number of rootstock suckers was counted and removed. This process was repeated over five time periods. In 2008, we grafted all of the plants below the rootstock cotyledons. During five different time periods spanning 57 d, bud regrowth from the rootstock occurred in all studied rootstocks in 2007. The difference in the 2 years was dramatic. In the first year, the number of plants with rootstock regrowth was as high as 84.6% in some of the plots for ‘Multifort’, 30.7% for ‘Aloha’, and 15.4% for ‘TX-301’. In the second year, with a different grafting technique, no regrowth from the rootstocks was observed. Even when the rootstock regrowth was removed in 2007, the rootstock sprout growth would reappear from the rootstock. The statistical interaction of the percentage of plants with rootstock regrowth for all recorded dates in 2007 was significant for ‘Multifort’ (Tukey-Fischer P ≤ 0.05) but not ‘Aloha’ or ‘TX-301’. Although the study also contained fumigation treatments, no interaction of soil treatments on root sprouting was observed. Since adopting this method, rootstock regrowth has not been observed in subsequent field experiments for the past 3 years.

In recent decades, wild sable (Carnivora Mustelidae Martes zibellina) habitats, which are often natural forests, have been squeezed by anthropogenic disturbances such as clear-cutting, tilling and grazing. Sables tend to live in sloped areas with relatively harsh conditions. Here, we determine effects of environmental factors on wild sable gut microbial communities between high and low altitude habitats using Illumina Miseq sequencing of bacterial 16S rRNA genes. Our results showed that despite wild sable gut microbial community diversity being resilient to many environmental factors, community composition was sensitive to altitude. Wild sable gut microbial communities were dominated by Firmicutes (relative abundance 38.23%), followed by Actinobacteria (30.29%), and Proteobacteria (28.15%). Altitude was negatively correlated with the abundance of Firmicutes, suggesting sable likely consume more vegetarian food in lower habitats where plant diversity, temperature and vegetation coverage were greater. In addition, our functional genes prediction and qPCR results demonstrated that energy/fat processing microorganisms and functional genes are enriched with increasing altitude, which likely enhanced metabolic functions and supported wild sables to survive in elevated habitats. Overall, our results improve the knowledge of the ecological impact of habitat change, providing insights into wild animal protection at the mountain area with hash climate conditions.

Abstract Background Undergoing cancer screening is a debatable topic in patients with cognitive impairment. In this study, we aimed to examine the utilization and predictors of breast and colorectal cancer screening among screening eligible, cognitively impaired individuals. Methods We analyzed the 2018 and 2019 National Health Interview Survey data (n = 12,965 and 24,782, respectively) on individuals eligible for breast or colorectal cancer screening. We calculated the percentage of cancer screening eligible individuals who received mammogram or colonoscopy by cognitive impairment status. We used multivariable logistic regression to examine whether having a recent mammogram or colonoscopy differed by cognitive impairment status, adjusting for covariates. Results We observed a significantly lower percentage of mammogram use in the screening eligible, cognitively impaired (mild or severe) versus unimpaired women. Adjusting for the covariates, the cognitively impaired women, mild (odds ratio [OR] = 0.85; p = 0.015) or severe (OR = 0.54; p <  0.001), were less likely to have had a recent mammogram compared to the cognitively unimpaired women. Although statistically non-significant, the percentage of colonoscopy use in the screening eligible, cognitively impaired individuals were slightly higher than that in the cognitively unimpaired individuals. In the regression analysis, we found the cognitively impaired men, mild (OR = 0.79; p <  0.001) or severe (OR = 0.69; p = 0.038), were less likely to have had a recent colonoscopy compared to the cognitively unimpaired men. More studies are needed to examine the multilevel factors that underpin the difference in cancer screening utilization in this vulnerable population. Conclusion Our results highlight the need for additional research to address utilization and effectiveness of cancer screening in individuals with cognitive impairment.

The time of occurrence of 12 neuromuscular patterns of behavior in the development of 2 groups of Negro infants from different socio-economic levels during the first year of life is presented. The Negro infants from the clinic showed acceleration over the Negro infants from private practice in their development from the 8th to the 35th week of life, after which time, the development of the 2 groups was essentially the same. The Negro infants as a group showed acceleration in their development when compared with a group of white infants studied in a similar manner by Aldrich except in 2 patterns, "smiling" and "vocalization." A marked similarity was noted during the first 30 weeks of life in the development of the white and Negro infants from private practice whose socio-economic backgrounds were substantially similar. The differences and similarities observed in the neuromuscular behavior in the 3 groups studied may be attributed mainly to environmental factors. The observed acceleration in the Negro infants is apparently an expression of greater permissiveness in daily care as practiced by the mothers or mother substitutes in the lower socio-economic classes.

The Impact

Abstract Background: Despite the increasing number of studies on gardening and health, evidence of health benefits of community gardening is limited by cross-sectional design. The “JArDinS” quasi-experimental study aimed to assess the impact of community garden participation on the adoption of more sustainable lifestyles in French adults. Methods: Individuals starting gardening in community gardens in Montpellier (France) in 2018 (N=66) were compared to pairwise matched individuals with no experience in community gardening (N=66). Monthly household food supplies, physical activity measured by accelerometers and questionnaires on physical, mental and social well-being, sensitivity to food waste, and connection with nature were used to explore sustainability of lifestyles in social/health, environmental and economic dimensions. Data were collected at baseline (t0) and 12 months later (t1). Linear mixed models were used to determine the independent effect of community gardening on investigated lifestyles components. In-depth interviews were conducted at t1 with 15 gardeners to better understand changes that may have occurred in gardeners’ lives during the first year of gardening.Results: At t0, gardeners had lower education level, lower BMI and reported lower percentage of meals consumed outside of the home in total household meals compared to non-gardeners (p<0.05). At t1, the mean weight of fruit and vegetables harvested from the garden was 19.5g/d/p. Participating in the community garden had no significant impact on any of the social/health, environmental and economic lifestyle components investigated. Qualitative interviews suggested the existence of pre-established health and environmental consciousness in some gardeners and revealed several barriers to the participation such as lack of time, lack of gardening knowledge, difficulty of gardening, health problems and conflicts with other gardeners. Conclusions: Using a longitudinal design allowing causality assessment, no impact was observed of the first year of community gardening on lifestyle sustainability. The pre-established sensitivity to sustainability and the various barriers encountered by new gardeners might explain the absence of community gardening impact. Further rigorous longitudinal studies are needed to determine whether or not community gardening is a relevant public health tool.Trial registration: The study was registered at clinicaltrials.gov as NCT03694782. Date of registration: 3rd October 2018, retrospectively registered.

&lt;p&gt;Soil microbial communities perform vital ecosystem functions, such as the decomposition of organic matter to provide plant nutrition. However, despite the functional importance of soil microorganisms, attribution of ecosystem function to particular constituents of the microbial community has been impeded by a lack of information linking microbial function to community composition and structure. Here, we propose a function-first framework to predict how microbial communities influence ecosystem functions.&lt;/p&gt;&lt;p&gt;We first view the microbial community associated with a specific function as a whole, and describe the dependence of microbial functions on environmental factors (e.g. the intrinsic temperature dependence of bacterial growth rates). This step defines the aggregate functional response curve of the community. Second, the contribution of the whole community to ecosystem function can be predicted, by combining the functional response curve with current environmental conditions. Functional response curves can then be linked with taxonomic data in order to identify sets of &amp;#8220;biomarker&amp;#8221; taxa that signal how microbial communities regulate ecosystem functions. Ultimately, such indicator taxa may be used as a diagnostic tool, enabling predictions of ecosystem function from community composition.&lt;/p&gt;&lt;p&gt;In this presentation, we provide three examples to illustrate the proposed framework, whereby the dependence of bacterial growth on environmental factors, including temperature, pH and salinity, is defined as the functional response curve used to interlink soil bacterial community structure and function. Applying this framework will make it possible to predict ecosystem functions directly from microbial community composition.&lt;/p&gt;

The purpose of conducting this research is to examine the difference NGain scores between students who learn vocabulary with Blindfold Game and students who learn vocabulary without Blindfold Game at the first year students of SMP Negeri 13 Kendari. The samples of this research are the first grade four (VII-4) and the first grade three (VII-3) which consists of 27 students for each class. This research is conducted in comparison research design that consists of experimental class (VII-4) and controll class (VII-3). The data of this research are collected by giving pre-test and post-test in two classes (VII-4 & VII-3). The result shows that there is an improvement of the students’ vocabulary achievement. Independent samples t-test shows that, there is a significant difference in the Ngain scores for experimental class ( M = 60.08,  SD = 9.36 ) and controll class ( M = 20.41, SD = 14.56 ), t (52) = 11.904, p (0.000) < 0.05. Therefore, it can be concluded that the value of Sig (2 tailed) is lower than the significance α value (0.000 < 0.05). In other words, alternative hypothesis (H1) is accepted and the null hypothesis (H0) is rejected. It means that the Blindfold game can enrich students’ vocabulary achievement for Junior High School Student.

Background: amyotrophic lateral sclerosis (ALS) is a motor neuron degenerative disease with high mortality and few therapies. One of these is riluzole, inspite of uncertainty effectiveness. Objective: the aim of this study was to evaluate the survival rate associated with the use of this medication in the treatment of ALS. Methods: The study was based on a narrative review of the scientific articles that used randomized controled trials with riluzole for ALS. We selected articles published in english during the period of January 1th, 2000 to December 31th, 2020. The MeSH terms “amyotrophic lateral sclerosis” or “motor neuron disease” and “riluzole” or “rilutek” were used in Pubmed and Lilacs databases. Studies that used only patients with advanced stage ALS were excluded. The t-Student test between sample means was applied to determine the significance of the difference between the survival time (years) of the riluzole and placebo treatment, for a 95% confidence level. Results: through the search, four articles were obtained (Table 1). Conclusion: Data analysis showed that riluzole is only effective in the first year. From the second onward, it does not exceed the results of the placebo.
