The studies were conducted on 2–3-months-old males of mice weighing 20–24 g. Оur work was to study the functional state of the organs of the immune system of C57Bl/6 mice after introduction of allogeneic MSCs of adipose tissue origin. Obtaining and cultivating of MSCs were carried out in a sterile laminar box with compliance of conditions of asepsis and antiseptics. C57Bl/6 mice adipose tissue cultured in a CO2 incubator at 37 °C and 5% CO2 in DMEM with 10–15% of fetal bovine serum, 1% of antibiotic-antimycotic solution (Sigma-Aldrich, USA). The following groups of animals were formed: 1 group – intact (control group); 2 group – animals, to whom 0.5 ml of 0.9% NaCl solution (placebo) were injected into the caudal vein; 3 group – animals, to whom were injected 104 of allogeneic MSCs from adipose tissue in 0.5 ml of phosphate buffer solution into the caudal vein. The weight index, content of lymphoid cells of thymus and spleen in C57Bl/6 mice investigated after the introduction of MSCs on 7, 18 and 25 days. To assess the content of lymphocytes in lymphoid organs, the latter were weighed. Whole thymus and 50 mg of spleen were triturated and filtered through the kapron tissue. After that, the tissue homogenate was applied to the gradient of ficoll-urografin (density 1.077) in a ratio of 3:2. The test tubes were centrifuged at a rate of 1500 rpm for 30-40 minutes. After centrifugation the layer of lymphocytes which was above the gradient was collected by a Pasteur pipette and washed twice with an arbitrary amount of Hanks' solution by centrifugation at a rate of 1500 for 10 minutes. 1 ml of Hanks's solution was added to lymphocytes after washing. Lymphocytes were counted in the Goryaev chamber. Calculation of the cells of lymphoid organs was performed on 1 mg of tissue. The administration of allogenic adipose derived mesenchymal stem cells affects on the central and peripheral organs of the immune system. Administration of allogenic adipose derived mesenchymal stem cells cause a significant increase in the content of lymphoid cells in the thymus at 7, 18 and 25 days by 71, 57 and 53% respectively (P < 0.05) compared to the control. Weight index of the thymus directly correlates with the content of lymphoid cells and its value was r = 0.57, P < 0.01 on 7 day and 18 day r = 0.50, P < 0.05. Quantity lymphoid cells in the spleen significant increase at the 7 and 18 days of the immune response by 33 and 19%, respectively (P < 0.01, P < 0.05) compared to the control under administration of allogenic adipose derived mesenchymal stem cells. On the 25th day of experience, the content of lymphoid cells in spleen and spleen index values return to normal. Weight index of the spleen directly correlates with the content of lymphoid cells – r = 0.91–0.94 (P < 0.001).

In other words, the quality of municipal drainage works directly relates to the development of urban processes and the quality of life of urban residents. Therefore, it is very important to ensure the quality of the municipal drainage project. This article briefly discusses the construction technology and quality control of municipal drainage engineering. Seeking for critical technologies in the construction of municipal drainage projects to provide a strong guarantee for the development of cities and people’s lives.
A participation model based on community forum as a reproductive health knowledge transaction space to increase male participation in vasectomy
Authors: Duadji Noverman , Tresiana Novita 
Published: June 2018

The first background of this research is the low participation of male vasectomy KB due to lack of information and low male contraceptive services. The second background of this research is Friedmann’s (2011) idea of citizen forum as transaction space which becomes communication media in the form of equal dialogue.This study aims to analyse the causes of low participation in the vasectomy method of family planning (KB) in South Lampung Regency; analyse the grassroots organisations in the community as the support system for a potential increase in the society’s participation in vasectomy as a part of family planning (KB); and develop a model of vasectomy to increase the participation in South Lampung Regency. This study utilised primary and secondary data which were collected and analysed using qualitative-descriptive method. The research was conducted in nine villages in South Lampung Regency. The findings showed that the major failure for participation in the vasectomy method of family planning (KB) was caused by a lack of a representative knowledge transaction space in family planning (KB) and reproductive health. On the other hand, the existing active societal-institutional support system can be utilised as the space for knowledge transaction. A solution to enhance a social participation model through community forums is urgently needed.

Authors: Rustinsyah Rustinsyah 
Published: June 2018

The existence of a cement company in a rural area may influence the local people, including women who are not employed by the company. This study aims at presenting the case of women empowerment in a Ring-1 area of a cement company in Indonesia. The research used qualitative approach. The results show that the company’s existence with its CSR programs have helped empowering rural women in social, educational, religious, organizational, and economic aspects. The social aspect is shown in the health programs. The educational aspect can be seen in the provision of scholarships for formal education and non-formal training. The religious aspect is actualized in the form of incentives for religion teachers and religious festivals. The organizational aspect is shown in the involvement of women in PKM management. Finally, the economic aspect includes: a) the construction of village road infrastructure as compensation of taxes derived from the company; b) the inclusion of workers from outside the village encourages the emergence of food stalls, grocery stalls, gasoline kiosks, and boarding houses; and c) the development of traditional markets. This study confirms that the company’s existence has encouraged rural women to improve their livelihoods and help alleviate their families from poverty.

There is growing interest in conducting public health research using data from social media. In particular, Twitter “infoveillance” has demonstrated utility across health contexts. However, rigorous and reproducible methodologies for using Twitter data in public health are not yet well articulated, particularly those related to content analysis, which is a highly popular approach. In 2014, we gathered an interdisciplinary team of health science researchers, computer scientists, and methodologists to begin implementing an open-source framework for real-time infoveillance of Twitter health messages (RITHM). Through this process, we documented common challenges and novel solutions to inform future work in real-time Twitter data collection and subsequent human coding. The RITHM framework allows researchers and practitioners to use well-planned and reproducible processes in retrieving, storing, filtering, subsampling, and formatting data for health topics of interest. Further considerations for human coding of Twitter data include coder selection and training, data representation, codebook development and refinement, and monitoring coding accuracy and productivity. We illustrate methodological considerations through practical examples from formative work related to hookah tobacco smoking, and we reference essential methods literature related to understanding and using Twitter data.

Published: June 2018

Incarceration is considerably more prevalent among sexual and gender minority persons (SGM) than among the general population. Once behind bars, they are at the greatest risk for health-related harms. Although a growing number of studies have assessed health disparities produced by mass incarceration, scholars are yet to systematically assess the health consequences of incarceration on the basis of sexual orientation and gender identity. We invite public health scholars to study the effects of incarceration on health in the SGM population and provide a roadmap to aid these research efforts. First, we document the disproportionate presence of SGM persons in jails and prisons. Second, we note health-related risks that are the most salient for this population. Third, we recommend examining heterogeneity in the effects of incarceration by teasing out distinct risks for groups defined by sexual orientation, gender identity, and race/ethnicity. Fourth, we note methodological challenges with respect to measurement and assessing causality. Finally, we discuss the importance of health care access and quality and the need to study health during incarceration and afterward.

Core Ideas
Intercropping cowpea with grain sorghum dramatically decreased sorghum grain yield.
Clover green manure only increased sorghum grain yield 1 out of 3 yr.
Fertilizer effects likely masked by mineralized organic matter from plowing of perennial pasture.
Crop residue decomposition was mostly unaffected by treatments.
Crop residue decomposition was largely driven by residue C/N ratios.
Legumes fix N, reduce fertilizer inputs for primary crops, and contribute C to soil organic matter (SOM), which benefits soil productivity and sustainability. Objectives of this study were to (i) maintain grain sorghum [Sorghum bicolor (L.) Moench] yields while decreasing N fertilizer requirements and build SOM using a temperate legume cover crop and tropical legume intercrop; (ii) quantify soil water usage between legume treatments and N fertilizer rates; and (iii) evaluate treatment effects on residue decomposition of each crop. In Overton, TX, crimson clover (Trifolium incarnatum L.) and cowpea [Vigna unguiculata L. (Walp)] were used as green manure and an intercrop, respectively, with grain sorghum. Four N fertilizer rates of 0, 45, 90, and 135 kg ha−1 were randomly assigned within a four replicate split‐split plot design on a Lilbert loamy fine sand. From 2010 through 2012, intercropped cowpea decreased sorghum grain yield between 77 and 93% compared to monocropped sorghum. Clover green manure increased sorghum grain yield 21% over winter fallow in 2012, but not significantly (P = 0.22). After 3 yr, soil organic C (12.4 g kg−1) and soil N (1.1 g kg−1) were 18% (P = 0.01) and 21% (P = 0.01) higher, respectively, for clover green manure compared to fallow at 0 to 15‐cm depth. Crop residue decomposition was relatively stable across years and only intercropping showed small increases in decomposition of grain sorghum residue. Overall, clover green manure proved to be a more sustainable choice than intercropping cowpea from both a yield and soil perspective.

Urea + NBPT and PCU provided significantly higher mean yields and net returns than conventional urea.
Urea + NBPT and PCU provided significantly lower yields and net returns than ammonium nitrate.
Urea + NBPT and PCU offer greater potential to improve net returns than urea + MICP.
This study determined the effects of enhanced efficiency (EE) urea fertilizers relative to ammonium nitrate (AN) on no‐tillage (NT) corn (Zea mays L.) yields and net returns (NRs) in Tennessee. Corn yields were from experiments conducted at two N fertilization rates of 123 and 168 kg ha−1 with four replications in a split‐plot design from 2013 through 2015 at three locations in middle (Springfield) and west Tennessee (Milan and Jackson). ANOVA analyses were used to identify differences in EE urea treatment yields and NRs. Breakeven and sensitivity analysis was used to compare yield and identify the threshold of positive NR of EE urea fertilizers relative to AN for a given premium price over conventional urea. Results indicated that urea + 20% or 26.7% N‐(n‐butyl)‐thiophosphoric triamide (NBPT) and polymer‐coated urea (PCU) provided significantly higher mean yields (2.0 Mg ha−1 more on average) and NRs ($283 ha−1 more) than conventional urea. Notwithstanding, these EE urea fertilizers had lower yields and produced lower benefits than AN in the course of this study. On the other hand, mean yield (8.7 Mg ha−1) and NR ($1012 ha−1) for urea + maleic–itaconic acid copolymer (MICP) were not significantly different from conventional urea (8.3 Mg ha−1 and $959 ha−1). In general, N fertilizer sources behaved similarly among N rates and locations. Given the growing reliance on urea fertilizer in NT corn production in Tennessee, urea + NBPT and PCU offer the greatest potential to improve expected NRs relative to conventional urea.
Corn Era Hybrid Macronutrient and Dry Matter Accumulation in Plant Components

Published: June 2018

Core Ideas
We compared 1960 and 2000 era hybrid DM and macronutrient partitioning.
Similar DM, N, P, and K accumulation patterns occurred for 1960 and 2000 era hybrids.
Nutrient concentrations (g kg−1) were lower for 2000 than 1960 era hybrids.
Plant component N, P, and K contents (kg ha−1) were greatest for 2000 era hybrids.
Greater modern hybrid nutrient uptake was mainly due to greater DM and yield.
As corn (Zea mays L.) hybrids change over time, and with increased use of different plant components for feed, bedding, and energy production, it is important to know macronutrient distribution within plants and how nutrient concentration and accumulation varies during plant development. This field study was conducted in 2007 and 2008 to evaluate dry matter (DM) biomass, macronutrient concentration, and macronutrient content in corn plant fractions (stalk, leaf, tassel, ear shoot, cob, and grain) across developmental stages with two hybrids from 1960 and 2000 eras. Concentrations of N, P, and K were generally lower in all plant fractions for the 2000 compared to 1960 era hybrids, except P concentration in stalks and grain and K concentration in leaves and ear shoots. In contrast, N, P, and K content was consistently higher in 2000 era hybrids for whole plants, leaves, and grain; a reflection of greater DM production. Nitrogen, P, K, and DM content in tassels was lower for 2000 than 1960 era hybrids. From the 1960s to 2000s, hybrid development brought about an increase in plant biomass and grain yield resulting in greater total nutrient content. However, macronutrient concentrations in vegetative plant fractions and grain decreased, thus moderating increase in plant total and grain nutrient content. This research shows the importance for analysis of newer hybrid vegetative and grain biomass on an ongoing basis to provide reliable estimates of macronutrient uptake patterns and removal with harvest of specific vegetative material and grain.
Cover Crops and Water Quality
Authors: Blanco‐Canqui Humberto 
Published: June 2018

Core Ideas
Cover crops increase time to runoff start and reduce runoff sediment loss.
Grass cover crops can be effective at reducing nutrient leaching.
Cover crops may have limited effect on reducing losses of soluble nutrients.
Use of cover crops may reduce the amount of herbicide used by suppressing weeds.
Reducing runoff sediment and nutrient loss as well as nutrient leaching from croplands is a high priority to mitigate nonpoint‐source pollution (NPSP) of water sources, maintain soil fertility, and improve overall soil and water quality. Adoption of cover crops (CCs) can be a reemerging strategy to address these concerns. This article reviews the state‐of‐knowledge of CC impacts on water quality parameters, discusses factors that affect CC impacts, and identifies research areas. The review indicates that CCs increase time to runoff start by 10 to 40 min, and reduce both runoff volume by 10 to 98% and sediment loss by 22 to 100%. The few studies indicate that CC effects on total and dissolved nutrients in runoff are not generally significant. Grass CCs such as rye (Secale cereale L.) can reduce nitrate leaching between 18 and 95%. Cover crop effectiveness can be in this order: nitrate leaching ≥ sediment > runoff > dissolved nutrients in runoff, indicating that CCs are highly effective at reducing nutrient leaching but can have limited effects on reducing transport of dissolved nutrients. More measured and modeled data evaluating CC effects on water quality under different CC management factors including planting and termination dates, CC species, CC mixtures or single species, and tillage systems are needed. Additionally, specific data on CC belowground biomass and their relations with soil erodibility are scanty. In conclusion, CCs can reduce runoff, sediment loss, and nitrate leaching, but may have smaller effects on reducing dissolved nutrients in runoff.

Chloramphenicol (CAP) is a broad‐spectrum antibiotic widely used in animal farming and aquaculture industries. Despite its ban in many countries around the world, it is still used in several developing countries, with harmful effects on the surrounding aquatic environment. In this study, an electrooxidation process using a Ti/PbO2 anode was used to investigate the degradation of CAP in both synthetic solution and real aquaculture wastewater. A central composite design was used to determine the optimum conditions for CAP removal. Current intensity and treatment time had the most impact on the CAP removal. These two factors accounted for ∼90% of CAP removal. The optimum conditions found in this study were current intensity of 0.65 A, treatment time of 34 min, and CAP initial concentration of 0.5 mg L−1. Under these conditions, 98.7% of CAP removal was achieved with an energy consumption of 4.65 kW h−1 m−3. The antibiotic was not present in the aquaculture wastewater, which received 0.5 mg L−1 of CAP and was treated (by electrooxidation) under the optimum conditions. A complete removal of CAP was obtained after 34 min of treatment. According to these results, electrooxidation presents an option for the removal of antibiotics, secondary compounds, and other organic and inorganic compounds from solution.Core Ideas

Abstract
A rapid increase in the risk of urban flooding in recent years has urged the research community to enrich approaches to deal with urban flooding problems. The state-of-the-art approach consists of coupling one-dimensional (1D) and two-dimensional (2D) hydrodynamic models. However, at present such coupled 1D/2D models are mostly commercial and complex to build and run. The present study has proposed a new simple approach for modeling urban flooding by coupling Storm Water Management Model (SWMM) and LISFLOOD-FP, two widely used freewares with relatively simple components. The coupled model was firstly applied to the Shiqiao Creek District in Dongguan City, South China, and verified against four major historical floods. The testing results demonstrate the capability of the coupled model in predicting urban flooding. The successful coupling of SWMM and LISFLOOD-FP offers another simple, practical approach for urban flooding estimation, which can be readily used by non-expert users or those who do not have access to commercial modules.

A sífilis é uma doença crônica causada pela bactéria Treponema pallidum, geralmente adquirida por contato sexual com outro indivíduo infectado. As gestantes fazem parte de um grupo epidemiológico importante, uma vez que não só são portadoras de sífilis, como também podem gerar crianças com sífilis congênita através da disseminação hematogênica transplacentária. Este estudo teve como objetivo realizar um levantamento epidemiológico da incidência de sífilis congênita no município de Vassouras, no estado do Rio de Janeiro e no Brasil. O levantamento foi realizado a partir dos informes epidemiológicos do município de Vassouras, RJ, do estado do Rio de Janeiro e do Brasil, nos últimos 15 anos. Os resultados mostraram que o município de Vassouras revelou uma taxa de incidência de sífilis congênita compreendida entre 2 e 4,4 casos/1000 nascidos vivos, em 5 anos alternados e inferiores as observadas aos índices do Brasil e do Rio de Janeiro, apresentando inclusive incidência zero em dez anos dos quinze anos analisados. Devido a sua importância, este estudo epidemiológico poderá contribuir com a qualidade dos serviços de Atenção Básica a Saúde da Mulher no município de Vassouras, RJ.
