Colchicine and SARS-CoV-2 prospects for clinical management of the inflammatory state

At date, research is moving for a direct SARS-CoV-2 antiviral, which will be, probably, the ideal solution to defeat the virus. In the meantime, evidences have shown that effective improvements for health status of infected patients can be found in the decrease or stop of the hyper inflammatory state. Experts have divided the SARS-CoV-2 infection in three phases. In the last one, phase 3, the most severe, the immune system goes an overdrive status and, as consequence, it launches a large-scale assault versus all the tissues. This phenomenon is known as “cytokine storm” and it can lead to a damage of organs and, in some cases to death. Several studies showed that blocking the cytokine storm or acting advance with a prevention of the phenomenon, can be effective; studies are ongoing to evaluate agents that can be able to reduce this hyperinflammatory state, as, for example, IL-6 or IL-1 inhibitors. However, other drugs that are able to block the cytokine cascade can also be considered. In this article is reported the scientific and molecular motivation related to the use of colchicine as monotherapy or in association in all three phases of infection by SARS-CoV-2 modulating the inflammatory state. Colchicine can be considered safe and effective for the treatment and prevention of Cytokine Storm in patients affected by SARS-CoV-2 infection, in particular as a remedy added to other therapeutical agents. In fact, colchicine, probably, provides a bigger benefit to all current agents and its safety profile is superior to the one provided by other drugs, such as corticosteroids and immunosuppressive drugs.
Investigation of underfilling BGAs packages – Thermal fatigue

Reliability of solder joint is one of the most concerns in the electronic packages. The trend of smart electronic devices decreases in size and thickness and demands more and more functionality which has required electronic packages to achieve the higher I/O density within a smaller chip size. Therefore, increased demand for flip chip fine-pitch Ball Grid Arrays (BGA) is inevitable. Fine-pitch BGA pushes the size of solder balls smaller, which has raised more concerns about the reliability of smaller BGA solder balls under mechanical or thermal load. Underfilling BGA has been considered a possible option to enhance the reliability of fine pitch BGA under mechanical vibrations. However, Underfilling BGAs can have an adverse outcome in terms of the thermal effect. Numerically, many researchers have investigated the effect of an underfill layer on the thermal reliability of BGA solder joints by observing accumulative plastic strain during thermal cycling. However, an experimental approach to quantify the amount of plastic strain accumulated after every thermal cycle has not been widely conducted. This work presents a novel experimental procedure to measure the plastic strain of the solder ball under thermal cycling with a two-dimensional digital image correlation (2D DIC) technique. By employing the experimental methodology with the 2D DIC presented in this work, the plastic strain accumulation during thermal cycling has been quantified. The accumulated plastic strain per cycle is one of parameters which helps to assess the impact of an underfilling layer on the thermo-mechanical reliability at second level interconnect.

Genetic characterization based on the D-loop MtDNA and the TSPY genes of the Dwarf Siamang (Hylobates klossii) of Mentawai Island, Indonesia

Hasanah R, Saepuloh U, Perwitasari-Farajallah DP, Sinaga W, Hastuti Y, Sajuthi D. 2020. Genetic characterization based on the D-loop MtDNA and the TSPY genes of the Dwarf Siamang (Hylobates klossii) of Mentawai Island, Indonesia. Biodiversitas 21: 2854-2861. Hylobates klossii is an endemic primate on the Mentawai Island, Indonesia that categorized as endangered species due to fragmentation, illegal hunting, and habitat loss. This study aimed to analyze the genetic characterization of H. klossii based on maternal and paternal lineages. The samples were collected from TSI (Bogor, Indonesia) cage consist of two males and two females (blood and fecal of four individuals) and Siberut Island, Mentawai, West Sumatra, Indonesia from one unknown gender (one individual fecal sample). PCR amplification was carried out on DNA and cDNA samples using specific primers for D-loop mtDNA and TSPY genes. The amplicon was analyzed with MEGA-7. The dimensional structure model of the TSPY protein was determined using I-TASSER and visualized with PyMol. The maternal analysis showed five samples consisted of four haplotypes revealed that Nam-nam and April were identic with 0% genetic distance. It’s revealed that Nam-nam and April were mother and son. The paternal analysis of two H. klossii males revealed that April was the closest relative to H. muelleri (99.56% identity) and Gou-gou to H. klossii (100% identity). Characterization of partial TSPY gene (990 bp) of April and Gou-Gou indicated four amino acids mutation, causing the shift in-amino acid structure position. The results assumed that April was a cross-breeding between H. klossii female and H. muelleri male. This genetic characterization is expected to support the conservation efforts through recommendations for good management in H. klossii preservation.
Joint Modeling of a Longitudinal Measurement and Parametric Survival Data with Application to Primary Biliary Cirrhosis Study

Although longitudinal and survival data are collected in the same study, they are usually analyzed separately. Measurement errors and missing data problems arise because of separate analysis of these two data. Therefore, joint model should be used instead of separate analysis. The standard joint model frequently used in the literature is obtained by combining the linear mixed effect model of longitudinal data and Cox regression model with survival data. Nevertheless, to use the Cox regression model for survival data, the assumption of proportional hazards must be provided. Parametric survival sub-models should be used instead of the Cox regression model for the survival sub-model of the JM where the assumption is not provided. In this article, parametric joint modeling of longitudinal data and survival data that do not provide the assumption of proportional hazards are investigated. For the survival data, the model with Exponential, Weibull, Log-normal, Log-logistic, and Gamma accelerated failure time models and the linear mixed effect model are combined with random effects and the models were applied in primary biliary cirrhosis data set obtained from Mayo Clinic. After determining the best parametric joint model according to Akaike and Bayesian information criterions, the best available model was compared with standard joint model and of separate analysis of survival data and longitudinal data. As a result, in the studies where longitudinal and survival data are obtained together, it is seen that the parametric joint model gives more better results than the standard joint model when the proportional hazard assumption is not provided.
21st Century Adoptive Families: A Longitudinal Study of Children Raised in Gay Father, Lesbian Mother and Heterosexual Parent Families

Findings are presented of a UK longitudinal study of adoptive families. At Phase 1, 41 gay father families, 40 lesbian mother families and 49 heterosexual parent families were visited when the children were aged between 3 and 9 years. At Phase 2, the response rate was 85%, with 33 gay father families, 35 lesbian mother families and 43 heterosexual parent families participating when the children were aged between 10 and 14 years. Standardized interview, observational, and questionnaire measures of parental mental health, parent-child relationships, and child psychological functioning were administered to parents, children, and teachers. Few differences were observed in parent mental health, the quality of parent-child relationships or in child psychological functioning. Where differences were identified, these reflected more positive functioning in gay father families compared to heterosexual parent families. In all family types, child adjustment problems significantly increased from Phase 1 (when the mean age of the children was 6 years) to Phase 2 (when the mean age of the children was 12 years). Moreover, a high proportion of children displayed adjustment problems at Phase 2: 31.6% scored above the cut-off for psychiatric disorder on the Strengths and Difficulties Questionnaire, a standardised questionnaire of children’s externalising and internalising problems, and 74.5% were rated by a psychiatrist as having some level of psychiatric concern. Though it is important to note that children generally displayed mixed attachment patterns (i.e. a combination of secure and insecure strategies), the dominant strategy for the majority of the sample (40.2%) was insecure-dismissing. Despite the high levels of adjustment problems and attachment insecurity, the children reported high levels of happiness and connectedness.

Teachers’ Empowerment, Self-Regulation and being Istiqamahas Key Features of Job Performance in Non-Formal Education Setting

Non-formal education is predicted to be the future backbone in supporting the literacy in highly populated country (Ololube, 2012). Indonesia as one of the E-9 countries have acknowledged the needs to strengthen the non-formal education as an important element in enhancing the education index. Both government and non-government organization have participated actively in establishing the non-formal education to be more accessible and convenience. The fundamental issue is that the teacher quality in education is still below expectation (Baswedan, 2014). Moreover, non-formal education has encountered dilemma in creating optimum performance of their teacher due to its non-profit nature. Nevertheless, it is evidenced that they still manage to deliver their jobs adequately. Therefore, this paper will investigate the determining factors of such unique setting. This study’s instruments are the psychological empowerment scale used by Spreitzer (1995), The Self-Regulation Questionnaire (SRQ) (Brown, Miller, & Lawendowski, 1999), Islamic work ethic scaling (Ali, 1988) and the questionnaire teachers’ job performance self-rating questionnaire (TJPSQ) were utilized as a measurement of teachers’ job performance. The result of the study indicates that empowerment and istiqamah have significantly influenced to teachers’ job performance, while self-regulations have no significant effect on Job performance.
Trading financial assets with actor critic using Kronecker-factored trust region (ACKTR)

Financial assets are a type of source of income for the retired. There are problems regarding decisions in managing financial assets. One way to manage financial portfolios is by using reinforcement learning. Reinforcement learning is a machine learning method that uses rewards and punishments as feedback for various learning agents to maximize cumulative rewards. This method requires a Markov Decision Process (MDP) environment to describe the problem to the learning agent. We will use Actor Critic using Kronecker-Factored Trust Region (ACKTR), which reduces the amount of sampling needed for learning. ACKTR excels in sample reduction by using Kronecker-Factored Approximated Curvature (K-FAC) and trust region in approximating the natural gradient for an agent’s learning. In this research, we use an MDP that describes personal retirement portfolio with securities, before implementing ACKTR and analyzing it. MDP used in this research is constructed as model-free MDP and total reward (cumulative reward) is influenced by discount rate and action. Results of this implementation shows that lower discount rates are superior to higher discount rates in average of cumulative rewards, and higher discount rates lead to riskier agents.
Optimal Switching of Micro-grid Distributed Management based on Equilibrium Models

Optimal switching has been proposed as a tool to improve the utility of the electricity grid among researchers in the electricity industry. In fact, according to Kirchhoff's rules, the restriction of the transmission of power from one path entails restrictions on the power passing through the corresponding parallel paths. Thus, in some operating conditions, opening a transmission line reduces the parallel paths and constraints imposed and, consequently, improves the network operating conditions. The effects of micro switching on market power in the power system are discussed first. To this end, the competition boundary problem has been developed to consider micro-switching. In this problem, the application of linear-integer models obtained on test networks shows that micro-switching can affect market power in a power system. This effect is further enhanced by the increase in HHI. Also, this effect is even greater at high load levels. This indicates the undesirable effect of micro-grid switching on market power if used without regard to market power. The following is a model for optimizing the micro-network periodic switching as a tool for system deployment to reduce the periodic cost of network deployment considering the market power of the actors. The results show that the optimal periodic switching of the microprocessor can reduce the operating costs of the whole period by considering the market power of the actors. Also, it reduces the market power of the actors compared to the case of micro-grid switching.
Solvent extraction of cobalt from laterite-ammoniacal leach liquors

The Bureau of Mines is developing a method to recover Ni, Co, and Cu from laterites containing less than 1.2% Ni and 0.25% Co. The method consists of the following basic unit operations: (1) reduction roasting, (2) leaching, (3) solvent extraction, and (4) electrowinning. The method reflects three Bureau of Mines objectives: (1) recovery of critical minerals that are domestically in short supply from low-grade domestic laterites, (2) lower processing energy requirements, and (3) solution recycling. This report deals with the extraction of cobalt and the preparation of a suitable cobalt electrolyte by solvent extraction from liquor produced by this method. Nickel and copper are coextracted with LIX64N from an ammoniacal ammonium sulfate leach liquor containing about 1.00 g/1 Ni, 0.30 g/1 Co, 0.03 g/1 Cu, and 0.02 g/1 Zn. Cobalt (III) in the nickel-copper barren raffinate is reduced to cobalt (II) with cobalt metal. Reduction of cobalt (III) to cobalt (II) greatly aids subsequent extraction. Commercially available XI-51 extracts about 94% of the cobalt from the treated raffinate in one stage in a laboratory mixer-settler continuous circuit. Ammonia loaded on the solvent is removed in two washing steps. About 94% of the cobalt then is stripped from the XI-51 more » in one stage with spent cobalt electrolyte containing about 77 g/1 Co and 18 g/1 sulfuric acid (H/sub 2/SO/sub 4/). Electrolytes containing less H/sub 2/SO/sub 4/ also may be used. Preliminary data indicate that coextracted zinc may be removed from pregnant cobalt electrolyte containing 3 g/1 or less H/sub 2/SO/sub 4/ with di-(2 ethylhexyl) phosphoric acid (D2EHPA). « less
1257-P: Impact of Parental Smoking on Adipokine Profiles and Cardiometabolic Risk Factors in Chinese Children: The Beijing Child and Adolescent Metabolic Syndrome Cohort Study

Exposure to secondhand smoke has relatively recently been recognized to be an important modifiable risk factor for obesity and cardiovascular disease, along with unhealthy diet, sedentary lifestyle and insufficient sleep. The mechanism(s) by which passive smoking imparts this risk and the tissues involved still require elucidation. We aimed to evaluate the association between parental smoking exposure (PSE), secretion of adipokines and cardiometabolic risk in Chinese children. A total of 3150 children (6-18ys) from the Beijing Child and Adolescent Metabolic Syndrome (MetS) study with data on PSE and potential confounders (pubertal stage, physical activity, diet and socioeconomic factors plus family history) were included. Six adipokines related to insulin resistance and MetS (leptin, adiponectin, retinol binding protein 4 (RBP4), fibroblast growth factor 21 (FGF-21), resistin and osteonectin) were measured. Of those children studied, nearly 65% reported PSE, defined as smoking in either parent. After adjusting for covariates, including pubertal stage, lifestyle factors, and family history, PSE was independently associated with increases of 39.2% in leptin and 3.9% in RBP-4 and decreases of 11.4% in FGF-21 and 4.6% in adiponectin levels (P Disclosure M.
