Computational Screening of Covalent Organic Frameworks for Hydrogen Storage
Authors: GÜLÇAY Ezgi , ERUCAR FİNDİKCİ İlknur
Published: November 2019

Covalent Organic
Frameworks (COFs) have been considered as promising materials for gas storage
applications due to their highly porous structures and tunable characteristics.
In this work, high-throughput molecular simulations were performed to screen
the recent Computation-Ready Experimental COF Database (CoRE-COF) for H2
storage a first time in the literature. Predictions for H2 uptakes
were first compared with the experimental data of several COFs. Motivated from
the good agreement between simulations and experiments, we performed Grand Canonical
Monte Carlo (GCMC) simulations to compute volumetric H2 uptakes of
296 COFs at various temperatures and pressures and identified the best
candidates which exhibit a superior performance for H2 storage. COFs
outperformed several well-known MOFs such as HKUST-1, NU-125, NU-1000 series,
NOTT-112 and UiO-67 at 100bar/77K adsorption and 5bar/160K desorption
conditions. We also examined the
effect of Feynman-Hibbs correction on simulated H2 isotherms and H2
working capacities of COFs to consider quantum effects at low temperatures.
Results showed that the Feynman-Hibbs corrections do not affect the ranking of materials based on H2
working capacities, but slightly affect the predictions of H2 adsorption
isotherms. We
finally examined the structure-performance relations and showed that density
and porosity are highly correlated with the volumetric H2 working
capacities of COFs. Results of this study will be highly
useful in guiding future research and focusing experimental efforts on the
best COF adsorbents identified in this study.

James in his epistle teaches the readers to ask God for wisdom when experiencing difficulties or trials. God as the source of wisdom generously gives wisdom to anyone who asks in faith. Wisdom from pure God bears the character of a holy and gentle God. Believers need to realize that they need wisdom so they have to ask for wisdom by truly believing and depending on God. Wisdom from God is evident in the way of believers’s life on how they act, behave and assess problems, understand God's plan, and take the right action. The results of God's wisdom for the lives of believers are the sanctified life, kindness, peace and blessing.
Hubungan Self-Esteem terhadap Level Kecemasan pada Mahasiswa Pogram Studi Pendidikan Agama Kristen [The Connection Between Self-esteem and the Anxiety Level in Christian Religious Studies Students]
Authors: Suparman Suparman
Published: November 2019

Levels of anxiety and self-esteem often affect students’ lives, even causing students to fail, unable to fulfil the academic requirements of lectures, and undergo the entire educational process. As a matter of fact, in general, students are not aware of this reality. Therefore, this study aims to find whether there is a relationship between the level of self-esteem and anxiety levels in Christian Religion Education students at UPH. In order to find the relationship between self-esteem and anxiety levels, this research is conducted in quantitative methods and the type of research is correlational. The sample is collecting between January and June 2019. As the results, students who classified as low self-esteem is 55% meanwhile 54% of students who have high levels of anxiety. The correlation between the two is -0.6. The negative correlation results indicate that the lower level of self-esteem will make the level of anxiety higher. The results of this study can be used to determine interventions, either through coaching, personal counselling, or through group therapy.
Preparation for Grace in Puritanism: An Evaluation from the Perspective of Reformed Anthropology
Authors: Thamrindinata Hendra
Published: November 2019

The Puritans’ doctrine on the preparation for grace, whose substance was an effort to find and to ascertain the true marks of conversion in a Christian through several preparatory steps which began with conviction or awakening, proceeded to humiliation caused by a sense of terror of God’s condemnation, and finally arrived into regeneration, introduced in the writings of such first Puritans as William Perkins (1558-1602) and William Ames (1576-1633), has much been debated by scholars. It was accused as teaching salvation by works, a denial of faith and assurance, and a divergence from Reformed teaching of human's total depravity. This paper, on the other hand, suggesting anthropology as theological presupposition behind this Puritan’s preparatory doctrine, through a historical-theological analysis and elaboration of the post-fall anthropology of Calvin as the most influential theologian in England during Elizabethan era will argue that this doctrine was fit well within Reformed system of believe.

Published: November 2019

Purpose of the study. To study lipid metabolism in chronic hepatitis C and to assess its impact on the formation of insulin resistance, steatosis and progression of liver fibrosis.

Materials and methods. The study included 205 patients with chronic hepatitis C (CHC). Conducts research, depending on the genotype C, viral load and body mass index (BMI) of the patients.

Results. CHC patients revealed a combined hyperlipoproteinemia on the background of op-pression synthesis of apolipoproteins A1 and B. Formation of hepatic steatosis was associated with HCV genotype 3 virus-induced viral load at ≥ 6 log10 IU/ml and metabolic in VL < 6 log10 IU/ml. In patients with chronic hepatitis C genotype 1, high viral load leads to inhibition of protein synthesis conveyor ApoA1 and increased synthesis of cholesterol, accompanied by abdominal obesity and the formation of insulin resistance. CHC patients with BMI < 25 kg/m2 viral load ≥ 6 log10 ME/ml was associated with dyslipidemia IV type on D. Fredriskson (1970), hyperglycemia, insulin resistance and diabetes. The advanced stage of liver fi brosis (F ≥ 3 on a scale METAVIR) and non-response to treatment were associated with a decrease in HDL cholesterol below normal. With an increase in viral load > 5 log10 ME/ml signifi cantly increased the risk of lipid and carbohydrate metabolism.

Published: November 2019

Afghanistan witnessed rapid urbanization in recent decades due to the post-war recovery process. When the war ended in 2001 by fall of Taliban regime, most Afghans refugees returned to urban areas of Afghanistan, especially in Kabul city. Moreover, the rapid urbanization, migration from rural areas, and population growth impacted on Kabul city with the manifestation of informal settlement. It is acknowledged that the residents of informal settlements suffer social, spatial, and economic exclusion from the benefit and opportunity of an urban environment. Furthermore, the residents of informal settlements experience disadvantages by geographical marginalization, shortage of basic infrastructure, improper governance framework, vulnerability into the effect of poor environment, and natural disaster. With all the above, the problems of informal settlements are considered challenges for and informal residents. Thus, it is a dire need to tackle and overcome problems of informal settlements. Therefore, this paper aims to identify the most proper approaches to addressing informal settlement problems in District13 of Kabul city. In order to reach this aim, interviews and a questionnaire survey have been conducted with government officials and local inhabitants. And the finding of this paper indicates that through the resident’s preferences, government capacity, and District 13 physical condition there are three approaches which can be implemented and adopted for improvement of informal settlement in District 13 of Kabul city, which is settlement upgrading as the first option, the land readjustment as the second option and urban redevelopment as the last option.

Published: November 2019

Mediterranean catchments are characterized by significant spatial and temporal hydrological variability caused by the interaction of natural as well human-induced abiotic and biotic factors. This study investigates the (non-)linearity rainfall-runoff relationship at multiple temporal scales in representative small Mediterranean catchments (i.e., < 10 km2) to achieve a better understanding of the hydrological response. Rainfall-runoff relationship was evaluated in 44 catchments at annual and event –203 events in 12 of these 44 catchments– scales. A linear rainfall-runoff relation was observed at annual scale with higher scatter in pervious than impervious catchments. Larger scattering was observed at event scale, although pervious lithology and agricultural land use promoted significant rainfall-runoff linear relations in winter and spring. These relationships were particularly analysed during five hydrological years in Es Fangar catchment (3.35 km2; Mallorca, Spain) as a temporal downscaling to assess intra-annual variability in which antecedent wetness conditions played a significant role in runoff generation.

Authors: Leca Cristian-Liviu , Nicolaescu Ioan , Ciotirnae Petrica
Published: November 2019

Wi-Fi fingerprinting positioning systems have been deployed for a long time in location-based services for indoor environments. Combining mobile crowdsensing and Wi-Fi fingerprinting systems could reduce the high cost for collecting the necessary data enabling the deployment of the resulting system for outdoor positioning in areas with dense Wi-Fi coverage. In this paper, we present the results attained in the designing and evaluation of an urban fingerprinting positioning system based on crowdsensed Wi-Fi measurements. We first asses the quality of the collected measurements, highlighting the influence of received signal strength on data collection. We then, evaluate the proposed system by comparing the influence of the crowdsensed fingerprints on the overall positioning accuracy for different scenarios. The evaluation helps gain valuable insight into the design and deployment of urban Wi-Fi positioning systems while also allowing the proposed system to match GPS-like accuracy in similar conditions.
C-S & S-C Monitoring of Time and Cost Variances of Schedule Using Complex Earned Value Method Indicators
Authors: Przywara Daniel , Rak Adam
Published: November 2019

Planning and implementation of construction projects are difficult processes and are burdened with many risk elements. The budget spread over time, which is developed on the basis of the schedule, presents the expected distribution of costs throughout the duration of the works, which during the implementation of the project is subject to constant changes resulting from time, cost and organizational factors. Managing construction contracts requires managers to be able to analyze on an ongoing basis the variances of production costs - from the values calculated in the offer cost estimate and assumed in the Budgeted Cost of Work Scheduled. The article attempts to analyze the emerging time and cost variances using proprietary C-S and S-C monitoring, based on simple indicators of the EVM method. An example of construction of a multi-family housing development was used to study the variances of planned and incurred costs.
Towards Sustainable Entrepreneurship Holistic Construct
Authors: Konys Agnieszka
Published: November 2019

In the recent years, conducted businesses have been increasingly expected to obtain more sustainable forms, with many added determinants. Indeed, sustainability-related entrepreneurship still faces complex choices among conventional entrepreneurial factors while being urged to consider three main pillars of sustainability. Thus, this work is focused on the development of a sustainability-related entrepreneurship by reflecting the sustainable needs of an entrepreneurship. Due to the fact that it is not clear for the sustainability-related entrepreneurship what the valuable and most influential factors stimming its development are, the detection of the underpinning building blocks that properly adapting within each factor and how these factors correlate with each other become a major motivation of this work. Therefore, this paper aims to conduct an attempt to identify comprehensive set of SE (Sustainable Entrepreneurship) factors providing a structural overview in making insights into the factors/determinants of SE. It assists researchers and entrepreneurs in obtaining clear informative pictures about SE factors. The applied research methodology is based on a systematic literature review which is conducted using the PRISMA methodology, simultaneously ensuring repetitiveness and lack of bias in this process. To retrieve and condense the immense amount of bibliographic information, a bibliometric analysis is adopted to perform in co-occurrence analysis of keywords determining SE factors and detailed different forms of distribution analysis. The expected outcome is to provide the classification schema of applied keywords in sustainable entrepreneurship literature as part of a comprehensive literature review, which is presented in order to uncover, classify and systematize the current research. As a result, a co-word matrix of high frequency keywords of SE factors is also established. It offers a feasible path of investigation for researchers aiming to build a consistent body of knowledge about sustainable entrepreneurship, by providing a conceptualization and systematization that can be applied across the many contexts in which sustainable entrepreneurship is expressed, for example sustainable actions and sustainable development contexts. The present research aims to yield a successful attempt of identifying comprehensive set of SE factors, as well as to establish a co-word matrix of high frequency keywords of SE factors. Providing a macroscopic overview of the main factors of SE in the form of conceptualization of the proposed construct will capture the unique organizational characteristics of sustainable enterprises and facilitate the research into capability building, innovation and competitive advantage in sustainable enterprises. It supports both researchers and entrepreneurs in shaping up and refining future research activities and investments in line with the policy of SE.

Chan and colleagues in their paper titled “Human origins in a southern African palaeo-wetland and first migrations” (https://www.nature.com/articles/s41586-019-1714-1) report 198 novel whole mitochondrial DNA (mtDNA) sequences and infer that ‘anatomically modern humans’ originated in the Makgadikgadi–Okavango palaeo-wetland of southern Africa around 200 thousand years ago. This claim relies on weakly informative data. In addition to flawed logic and questionable assumptions, the authors surprisingly disregard recent evidence and debate on human origins in Africa. As a result, the emphatic and high profile conclusions of the paper are unjustified.
A Robot's Response Acceleration Using the Metric Dimension Problem
Authors: Badr Elsayed , Aloufi Khalid
Published: November 2019

Consider a robot that is navigating in a space modeled by a graph, and that wants to know its current location. It can send a signal to determine how far it is from each landmark among a set of fixed landmarks. We study the problem of computing the minimum required number of landmarks, and where they should be placed so that the robot can always determine its location. Since the problem is an NP-complete problem, the robot's responses to the actions are slow. To accelerate this response, we can use the parallel version of this problem. In this work, we introduce a new parallel implementation for determining the metric dimension of a given graph. We run the proposed algorithm on a symmetric multi-processing (SMP) cluster using C programming language and the Message Passing Interface (MPI) library. Finally, we run our implementation on four categories of graphs (the tracks in which the robot moves): a cycle graph Cn, a path graph Pn, a triangular snake graph and a ladder graph Ln. Preliminary computational results indicate that the metric dimension problem is an NP-complete problem and prove the ability of the proposed algorithm to achieve a speedup of 6 for 8 processors.
On the Active Adsorption of Chromium(III) from Alkaline Solutions Using Multi-Walled Carbon Nanotubes
Authors: Alguacil Francisco J. , López Félix A.
Published: November 2019

The present investigation deals with the adsorption of chromium(III) from alkaline media using multi-walled carbon nanotubes. The adsorption of Cr(III) has been studied under various experimental conditions: stirring speed of the aqueous solution, initial metal and adsorbent concentrations, NaOH concentration in the aqueous solution, and temperature. The rate law indicated that chromium adsorption is well represented by the particle diffusion model, whereas the adsorption process fits to the pseudo-second order kinetic model within an exothermic character. Equilibrium data fit to the Langmuir type-2 equilibrium isotherm in an spontaneous process. Chromium(III) can be eluted from metal-loaded nanotubes using acidic solutions, from which fine chromium(III) oxide pigment can be ultimately yielded.
A Novel Application of Electroactive Polyimide Doped with Gold Nanoparticles: As a Chemiresistor Sensor for Hydrogen Sulfide Gas
Authors: Padua Lee Marvin G. , Yeh Jui-Ming , Santiago Karen S.
Published: November 2019

This research paper presents a new application of electroactive polyimide doped with gold nanoparticles (PI/AuNPs) as a chemiresistor sensor for detecting hydrogen sulfide gas. The synthesis of PI/AuNPs was done in a simple 3-step process of polymerization using the as prepared amine-capped aniline trimer (ACAT), followed by imidization, and doping. Spectral analyses via FTIR, LC-MS and 1H-NMR confirmed the formation of amine-capped aniline trimer with a MW of 288 g mol-1. Comparison of ACAT, BSAA, and PI FTIR spectra showed successful polymerization of the last, while XRD validated the incorporation of metal nanoparticles onto the polymer matrix showing characteristic diffraction peaks corresponding to gold. Furthermore, TEM, and FE-SEM revealed the presence of well-dispersed Au nanoparticles with an average diameter of about 60nm. The electroactive PI/AuNPs-based sensor showed a sensitivity of 0.29% ppm-1 H2S at a linear concentration range of 50 to 300 ppm H2S (r = 0.9777). The theoretical limit of detection was found at 0.142 ppm or 142 ppb H2S gas. The sensor provided a stable response reading at an average response time of 43±5 seconds, which was easily recovered after an average time of 99±5 seconds. The sensor response was highly repeatable and reversible with RSD values of 8.88%, and 8.60%, respectively. Compared with the performance of the conventional conducting polyaniline also doped with gold nanoparticles (PANI/AuNPs), the fabricated electroactive PI/AuNPs exhibited improved sensing performance making it a potential candidate in monitoring H2S in the environment and for work-related safety.

Contraception is a way to prevent the fusion of mature egg cell and sperm during the intercourse, so the fertilization will not occur. Some contraceptive methods in small animals have been evolved. This research aimed to determine the effects of kapok seed (Ceiba pentandra Gaertn) extract as contraception agent to the quality of spermatozoain domestic cats. The animals were divided into four group with each group consisted of six male cats. Group I, II, III was designated as the treatment groups and IV as the control group. The cats were given the emulsion of kapok seeds extract orally with concentration of 0,1%  b/v, 0,71 mg/kg BB, 0,36 mg/kg BB and 0,21 mg/kg BB doses. This study used Randomized Complete Random Design (RAL) design from sperm quality data and used ANOVA statistic test. The result showed that the concentration of sperm decreased in the treatment groups compared with the control group. Statistically, the sperm concentration decreased significantly (P < 0,05) between the control group and treatment groups. The average motility in low and medium doses was above 40% while it was below than 40% in the high doses group. Based on the results, the granting of kapok seed extract inhibited the viability of spermatozoa of cats with significant results (P < 0,05). Sperm abnormalities in this study was obtained from the control group with percentage average of 1 % , while it was significantly increased in the treatment groups marked by abnormalities in the shape of the head and tail of the spermatozoa. These results suggested that kapok seed extract can be used as one of the contraceptive agents in domestic cat (Felis domestica) because it can decrease the sperm quality significantly.

Cadmium (Cd) belongs to heavy metal with high anthropogenic pollutant and non-essential to physiological funtion. Regular intake of consuming Cd leads to physiological disorders in poultry animal as well as humans as one who consume it. The aim of this study was to analyze the profile of Cd content in environmental samples (poultry feed and water) and it correlated with the degree of contamination in broiler tissues. In this study, 30 samples of feeds and water samples along with 60 samples of liver and muscle have been examined. The results showed that the feed was indicated to Cd between 0.009-0.202 mg / kg and in the water between 0.0068-0.0096 mg / l. Cd in the livers and muscles was then positively contaminated by Cd between 0.438-0.565 mg / kg and the levels was significantly different (p <0.05) among organs. A strong positive correlation was found between Cd and water levels in liver (r = 0.896). In contrast, a weaker positive correlation (r = 0.596) was found in the water and muscle. In conclusion, Cd contamination in feed and water correlated positively with the increasing amount of the cadmium level in organs.

Published: November 2019

Abstract This study was conducted to improve the quality of oocytes in old-female rats by using pregnant mare serum gonadotrophin (PMSG). Female rats at productive age were used as a control.  The experimental rats were injected with 4 doses of PMSG i.e., 0, 2.5, 5.0, and 10 IU PMSG. After 2 weeks of acclimation to the experimantal condition, the experimental rats were injected with PGF2α at a dose of 25µg/g BW two times with 2 days interval to synchronize estrous cycle. PMSG injections were conducted at the same time with the second PGF2α injection.  After PMSG injection, the experimental rats were divided into two groups rats, i.e., rats without mating for masurement of oocyte qualities and rats mated for measurement of offspring qualities.  Therefore, 16 experimental rats from each age group were sacrifized for maeasurement of oocyte qualities.  The other 16 experimental rats for each age group were mated for measurement of offspring qualities. Parameters measured were hematological profile, uterine and ovarian weights, the qualities of oocytes, the qualities of the offsspring born by using swimming test and rat maze test. The collected data were analyzed by analysis of variance (ANOVA) and continued with Duncan test with a 95% confidence level. The data were analyzed using SSPS. The results showed that the improvement in the quality of oocytes in old female rats using the PMSG hormone in this study showed an increase in the quality of oocytes in old and productive age rats. The highest number of oocyte quality was found in rats of productive age (3.25) and significantly different (P< 0.05) from the other oocyte qualities. The quality of offspring born to old age and productive age rats injected with PMSG were improved.  It was concluded that the improvement of oocyte quality by using PMSG also improves offspring qualities.

A large rich gas condensate field in The Sultanate of Oman has been studied. 30 gas wells were drilled in the field producing 3 MMm3/d of gas and 450 m3/d of condensate from the Barik formation. Water production is negligible. A redevelopment study was initiated with value drivers focused on maximizing the gas and condensate development.

New wide azimuth seismic (WAZ) was interpreted and integrated with new petrophysical realizations and geological concepts. This has resulted in a 20% drop in both the GIIP and the CIIP. Earlier wells results and cores when fully re-evaluated support this conclusion. Petrophysical reinterpretation combined with production testing (PLTs) and sampling (MDTs) showed two potential contact scenarios. The field can either be interpreted as having one GWC or it can be interpreted as having an oil rim with a GOC and an OWC. Both of these interpretations result in very different predictions regarding volumetric recoveries, future well locations, and number of wells to be drilled.

Static and dynamic models based on these two broad realizations were then generated that capture all the known uncertainties.

For the Gas development value driver, a depletion case scenario was studied. For the condensate development value driver, a study of IOR and EOR methods was initiated covering water injection and water alternating gas, nitrogen injection, huff and buff, produced gas injection, and CO2 injection.

Wells and surface development concepts were also assessed for each of the development scenarios and the best option was then used in the economics evaluation.

In this study, a detailed finite element analysis methodology of a 180 m deck cargo/launch barge B42 for 32,000 MT topside load is described and results are presented. Using Finite Element Method (FEM) for large welded steel structures such as a deck cargo/launch barge has been quite challenging in past because the engineer had to observe the balance between solution accuracy and numerical efficiency. However, recent improvements in solver algorithms in FEM packages and increasing core processor numbers in computers enable engineers to include a lot more details to their FE model so that accurate stiffness and mass of the structure can be simulated. In this study, the entire barge is modelled in ANSYS Software using shell elements including longitudinal beams, stiffeners, flanges, base plates, skid tracks and outriggers.

Two most critical load cases were analyzed; the first is the maximum hogging condition which occurs in the topside loadout sequence where the topside is entirely on barge deck towards stern. The second load being the maximum sagging case where the topside is at the final location on the deck of barge for transportation.

Results of the detailed FE analysis confirmed the structural integrity of the barge showing all the stresses and displacements are below allowable limits for all load cases. Two main advantages were observed through detailed modelling of the entire barge. Firstly, a faster preprocessing time is as compared to shell-beam models. Secondly, increasing the mesh density in critical locations in global FE model will be equivalent to a sub-model in this case. Thus, eliminating the need for analyzing any detail separately.

Objective: To evaluate the visual outcomes of Contoura Vision with automatic eye tracking system in eyes with myopia and myopic astigmatism.
Methods: In this prospective study, 40 consecutive patients (80 eyes) with moderate myopia and irregular astigmatism were included from January to August 2018 at Liuzhou Worker’s Hospital. Subjects were randomly divided into an experimental group (40 eyes) that underwent Contoura Vision FS-LASIK and a control group (40 eyes) that underwent wavefront-optimized FS-LASIK. Target refractions of all subjects were plano. Visual outcomes and astigmatic vector analysis were evaluated and compared between preoperatively and 3 months post-operatively.
Results: The preoperative spherical and cylindrical refractive errors were similar in both groups (P>0.05). At 3 months postoperatively, cumulative uncorrected distance visual acuity (UDVA) was 20/16, 20/20, or 20/25 in 30 %, 95%, 100 % of patients in the experimental group, respectively. The experimental group was better than the control group in predictability of astigmatism correction at 3 months after operation. In the experimental group, 80% of eyes had deviation of astigmatic axis within 15° and 35% of eyes had deviation of astigmatic axis within 5°, both were better than those in the control group. The number of eyes with residual astigmatism within 0.5D were higher in the experimental group (60%, 24 eyes) than the control group (50%, 20 eyes). Compared with the preoperative, C7 significantly reduced to 0.056±0.030 in the experimental group at 3 months after the procedure (P<0.05), and were significantly lower than those in the control group (P<0.05).
Conclusion: Contoura Vision with automatic eye tracking system was safe and effective for the correction of myopia and myopic astigmatism.

ABSTRACT
Background
Safety-net health systems are an important source of healthcare for underserved or vulnerable individuals, but definitions of safety-net institutions are largely based on patient characteristics. Some definitions may not accurately identify such institutions. Therefore, we aimed to describe the characteristics of urban safety-net patients in Texas and compare the distribution of morbidities between safety-net and general population patients.
Methods
We used hospital claims data from the Dallas-Fort Worth Hospital Council Foundation to create a cross-sectional cohort. Eligible patients were aged ≥18 years and Tarrant County residents in 2018. Patients were divided into two groups for comparison. The first group represented patients with hospital claims from JPS Health Network (i.e. safety-net population). The second group represented all patients with hospital claims in Tarrant County (i.e. general population). We estimated frequencies of patient characteristics. In addition, we estimated overall and payor-stratified standardized morbidity ratios (SMRs) adjusted for age, gender, and race/ethnicity to compare the prevalence of common chronic diseases between safety-net patients and patients in the general population.
Results
Our study population comprised 459,827 patients, of whom 74,323 (16%) were safety-net patients. Patients aged ≥65 years comprised 23% of the general population and 11% of the safety-net population. Non-Hispanic Whites comprised 52% of the general population and 29% of safety-net patients. A larger proportion of safety-net patients were uninsured compared with general population patients (safety-net: 54%; general population: 25%), but Medicaid distribution was less discrepant (safety-net: 9%; general population: 7%). Medicare was the primary payor for 24% of general population patients and 14% of safety-net patients. Safety-net patients had relative excesses of mental health and chronic conditions ranging between 5% and 230% for all selected conditions except dementia/Alzheimer’s. The patterns for payor-stratified SMRs were consistent with the overall results.
Conclusions
We observed considerable sociodemographic diversity and a high burden of mental health and chronic conditions among safety-net patients, which may support understanding the healthcare needs of safety-net populations. Our findings raise questions about definitions of safety-net institutions based on Medicaid distribution alone and the transportability of findings from studies in which safety-net populations are unrepresented.

Background Type 2 diabetes (T2D) is a complex metabolic disease and has been proved to involve in the alternation of the gut microbiota. The previous studies primarily focused on the changes in bacteriome while ignoring the phage community composition. The extracellular phages could lyse the host bacteria, and thus influence the microbiota through the positive or negative interactions with bacteria. We investigated the change of extracellular phageome and explored its role in T2D pathogenesis.Results We used a sequencing-based approach to identify the bacteriophage after isolation of VLPs from the fecal samples. We identified 330 phages according to the predicted host bacteria. The phageome characteristics were highly diverse among individuals. In the T2D group, the intestinal phage population is altered and the abundance of 7 identified phages specific to Enterobacteriaceae hosts were found increased markedly. Additionally, the abundance of Enterobacteriaceae bacteria in gut was significantly increased and the systemic LPS elevation was observed in T2D group. Several phage consortia were found to have significant correlations with T2D disease indicators.Conclusions The alteration of bacteriophages predicted to infect Enterobacteriaceae in the gut was observed in this study, which was expected to be a new source of systemic LPS in T2D patients, and may contribute to the pathogenesis of the disease. The data present in this study revealed the similar variation trend in enteric bacteriome and the correlated bacteriophages, which is likely to shed considerable light on overall understanding the interactions between microbiome and metabolic diseases.

Background Traumatic brain injury (TBI) is a major cause of death and disability in young adults worldwide. TBI-induced long-term cognitive deficits represent a growing clinical problem.Stem cell factor (SCF) and granulocyte-colony stimulating factor (G-CSF)play a role in neuroprotection and neuronal plasticity.However, the knowledge concerning reparative efficacy of SCF+G-CSF treatment in post-acute TBI recovery remains incomplete. This study aims to determine the effectsof stem cell factor (SCF) and granulocyte colony-stimulating factor (G-CSF) on post-TBI recovery in young adult mice. The controlled cortical impact model of TBI was used for inducing a severe damage in the motor cortex of the right hemisphere in 8-week-old male C57BL mice. The combination treatment of SCF and G-CSF (SCF+G-CSF) was initiated 3 weeks after induction of TBI. Results Severe TBI led to persistent motor functional deficits (Rota-Rod test) and impaired spatial learning and memory (Morris water maze test). SCF+G-CSF treatment significantly improved the severe TBI-impaired spatial learning and memory at 6 weeks post-treatment.TBI also caused significant increases of Fluoro-Jade C positive degenerating neurons in bilateral frontal cortex, striatum and hippocampus, and significant reductions in MAP2+apical dendrites and overgrowth of SMI312+axons in peri-TBI cavity frontal cortex and in the ipsilateral hippocampal CA1 at 24 weeks post-TBI. SCF+G-CSF treatment significantly reduced TBI-induced neurodegeneration in the contralateral frontal cortex and hippocampal CA1, increased MAP2+apical dendrites in the peri-TBI cavity frontal cortex, and prevented TBI-induced axonal overgrowth in both the peri-TBI cavity frontal cortex and ipsilateral hippocampal CA1. Conclusions These findings reveal a novel pathology of axonal overgrowth after TBI and demonstrate a therapeutic potential of SCF+G-CSF in ameliorating TBI-induced long-term neuronal pathology, neural network malformation, and impairments in spatial learning and memory.
