Published: July 2021

Background
After many years of research on software repositories, the knowledge for building mature, reusable tools that perform data retrieval, storage and basic analytics is readily available. However, there is still room to improvement in the area of reusable tools implementing this knowledge.

Goal
To produce a reusable toolset supporting the most common tasks when retrieving, curating and visualizing data from software repositories, allowing for the easy reproduction of data sets ready for more complex analytics, and sparing the researcher or the analyst of most of the tasks that can be automated.

Method
Use our experience in building tools in this domain to identify a collection of scenarios where a reusable toolset would be convenient, and the main components of such a toolset. Then build those components, and refine them incrementally using the feedback from their use in both commercial, community-based, and academic environments.

Results
GrimoireLab, an efficient toolset composed of five main components, supporting about 30 different kinds of data sources related to software development. It has been tested in many environments, for performing different kinds of studies, and providing different kinds of services. It features a common API for accessing the retrieved data, facilities for relating items from different data sources, semi-structured storage for easing later analysis and reproduction, and basic facilities for visualization, preliminary analysis and drill-down in the data. It is also modular, making it easy to support new kinds of data sources and analysis.

Conclusions
We present a mature toolset, widely tested in the field, that can help to improve the situation in the area of reusable tools for mining software repositories. We show some scenarios where it has already been used. We expect it will help to reduce the effort for doing studies or providing services in this area, leading to advances in reproducibility and comparison of results.

Published: July 2021

Background: Polycystic ovary syndrome (PCOS) is a complex medical condition characterized by elevated androgen levels, menstrual irregularities, and small cysts on one or both ovaries. The prevalence of PCOS is 6 to 10% in women. C-reactive protein (CRP) is an acute-phase protein produced by the hepatic cells and it’s levels increased in inflammation that increases interleukin-6 by macrophages and T cells.
Aims and Objective: A correlative study of role and usefulness of CRP in women with PCOS and its correlation with different biochemical parameters.
Materials and Methods: This was hospital based case-control study carried out among PCOS was conducted in the Department of Obstetrics & Gynaecology, Index Medical College Hospital, Indore. This study was conducted from 1st January 2018 to 31st December 2019. A total of 260 subjects with age group between 15 to 45 years were divided into two group; cases (130) and controls (130).
Results: Among a total of 260 cases, based on clinical and different biochemical parameters, 130 were diagnosis with PCOS and 130 were apparently healthy women. The mean ±SD of various parameters among PCOS cases were; body mass index (BMI) 32.97±8.466, P (<0.001) total cholesterol (TC) 188.42±31.126, P (<0.001), triglyceride (TG) 134.43±50.01, P (<0.001), high density lipoprotein (HDL) 36.29±9.55 TC/HDL ratio, 5.54±1.865 serum CRP, 3.41±0.94 versus BMI 22.87±2.470, P (<0.001), TC155.42±26.333, TG 110.00±42.19, HDL 41.22±10.912, TC/HDL ratio 4.08±1.39, serum CRP 2.25±0.83 P (<0.001) in healthy control.
Conclusion: In this study, the role of inflammation and different biochemical markers were studied among PCOS. It was found that a majority of PCOS patients were obese, having insulin resistance. The levels of CRP as a marker of chronic low grade inflammation were higher in newly diagnosed PCOS as compared to the controls. The CRP values correlated well (statistically significant) with increased in BMI and age.

Ceiba pentandra and Parmotrema perlatum lichen are two illustrious spices. Apart from their benefit as aromas, These are known for various therapeutic activities. Both are well known as appetizers. Decoctions of theses powders are used to relieve cough, anorexia and helminthiasis etc. Though several studies on antimicrobial activities of these two plants are available, studies on resistant microorganisms and anti tubercular activity are very limited. Hence, the author made an attempt to identify the phytochemical constituents present in methanolic and n-hexane extracts of Ceiba pentandra and Parmotrema perlatum using phytochemical tests and GC-MS method then to evaluate antibacterial activity against 5 resistant microorganisms by microtitre broth dilution method using ciprofloxacillin & streptomycin as reference standards. Methanolic extracts of Parmotrema perlatum and Ceiba pentandra had shown a considerable antibacterial activity than n-hexane extracts and exhibited 90% growth inhibition against H37Rv resistant strain of mycobacterium at 80 & 320 micrograms/ml respectively. N-hexane extracts of both species were found to be poorly effective against H37 Rv.

Background: Hookworm is an intestinal parasite of human and is one of the major public health burdens in developing countries, particularly in Sub-Saharan Africa. It is estimated that about 3.5 billion people globally and 450 million people are thought to be ill as a result of such infections, the majority being children.
Aims: The study aimed to determine the prevalence of Hookworm and other intestinal parasitic infection among primary school children
Study Design: This was a cross-sectional, descriptive study
Place and Duration of Study: This study was conducted in among patients attending Usmanu Danfodiyo University, Teaching Hospital, Sokoto, Sokoto state, between March to November, 2017.
Methodology: A total of 224 participants were enrolled for the study. Standard parasitological examination was carried out on stool samples using microscopy followed by formal ether concentration methods
Results: Finding revealed, an overall prevalence of 4.5% out of 224 samples examined recorded for both Hookworm and other intestinal parasitic infection. There was high prevalence rate of Hookworm and other intestinal parasitic infection among males (5.3%) than females (3.6%).29 (12%) were positive for intestinal parasitic infections. Males recorded higher prevalence than the females with 19 (11.9%) and 10 (11.8%) respectively
Conclusion: The total low prevalence rate of Hookworm and other intestinal parasitic infection may be as a result of improved standard of living and awareness of the Hookworm and other intestinal parasites in the study area. The government, non-governmental agencies and private individuals should help in the provision of social amenities to ensure total eradication of these diseases. The teaching of health education in both private schools should be encouraged by the government which will go a long way in reducing prevalence and intensity of Hookworm infections among the study community.

AbstractBeyond the catalytic activity of nanocatalysts, the support with architectural design and explicit boundary could also promote the overall performance through improving the diffusion process, highlighting additional support for the morphology‐dependent activity. To delineate this, herein, a novel mazelike‐reactor framework, namely multi‐voids mesoporous silica sphere (MVmSiO2), is carved through a top‐down approach by endowing core‐shell porosity premade Stöber SiO2 spheres. The precisely‐engineered MVmSiO2 with peripheral one‐dimensional pores in the shell and interconnecting compartmented voids in the core region is simulated to prove combined hierarchical and structural superiority over its analogous counterparts. Supported with CuZn‐based alloys, mazelike MVmSiO2 nanoreactor experimentally demonstrated its expected workability in model gas‐phase CO2 hydrogenation reaction where enhanced CO2 activity, good methanol yield, and more importantly, a prolonged stable performance are realized. While tuning the nanoreactor composition besides morphology optimization could further increase the catalytic performance, it is accentuated that the morphological architecture of support further boosts the reaction performance apart from comprehensive compositional optimization. In addition to the found morphological restraints and size‐confinement effects imposed by MVmSiO2, active sites of catalysts are also investigated by exploring the size difference of the confined CuZn alloy nanoparticles in CO2 hydrogenation employing both in‐situ experimental characterizations and density functional theory calculations.
A Partial Sulfuration Strategy Derived Multi‐Yolk–Shell Structure for Ultra‐Stable K/Na/Li‐ion Storage

Published: July 2021

AbstractMetal sulfides are attractive anodes for alkali metal ion batteries due to the high theoretical capacity, while their practical implementation is hampered by the inherent poor conductivity and vast volume variation during cycles. Approaching rational designed microstructures with good stability and fast charge transfer is of great importance in response to these issues. Herein, a partial sulfuration strategy for the rational construction of multi‐yolk–shell (m‐Y–S) structures, from which multiple Fe1−xS nanoparticles are confined within hollow carbon nanosheet with tunable interior void space is reported. As anode materials, the m‐Y–S Fe1−xS@C composite can display high capacity and excellent rate capability (134, 365, and 447 mA h g−1 for K+, Na+, and Li+ storage at 20 A g−1). Remarkably, it exhibits ultra‐stable potassium storage up to 1200, 6000, and 20 000 cycles under current densities of 0.1, 0.5, and 1 A g−1, which is much superior to previous yolk–shell structures and metal‐sulfide anodes. Based on comprehensive experimental analysis and theoretical calculations, the exceptional performance of m‐Y–S structure can be ascribed to the optimized interior void space for good structure stability, as well as the multiple connection points and conductive carbon layer for superior electron/ion transportation.

Published: July 2021

AbstractPhysical organ models are the objects that replicate the patient‐specific anatomy and have played important roles in modern medical diagnosis and disease treatment. 3D printing, as a powerful multi‐function manufacturing technology, breaks the limitations of traditional methods and provides a great potential for manufacturing organ models. However, the clinical application of organ model is still in small scale, facing the challenges including high cost, poor mimicking performance and insufficient accuracy. In this review, the mainstream 3D printing technologies are introduced, and the existing manufacturing methods are divided into "directly printing" and "indirectly printing", with an emphasis on choosing suitable techniques and materials. This review also summarizes the ideas to address these challenges and focuses on three points: 1) what are the characteristics and requirements of organ models in different application scenarios, 2) how to choose the suitable 3D printing methods and materials according to different application categories, and 3) how to reduce the cost of organ models and make the process simple and convenient. Moreover, the state‐of‐the‐art in organ models are summarized and the contribution of 3D printed organ models to various surgical procedures is highlighted. Finally, current limitations, evaluation criteria and future perspectives for this emerging area are discussed.
Early developmental impact of sex chromosome trisomies on attention deficit‐hyperactivity disorder symptomology in young children

Published: July 2021

AbstractIndividuals with sex chromosome trisomies ([SCT], XXX, XXY, and XYY)) are at increased risk for neurodevelopmental problems, given that a significant portion of the sex chromosome genes impact brain functioning. An elevated risk for psychopathology has also been described, including attention deficit‐hyperactivity disorder (ADHD). The present study aimed at identifying early markers of ADHD, providing the first investigation of ADHD symptomology in very young children with SCT. The variety, type, and severity of ADHD symptomology in 1–6‐year‐old children with SCT (n = 104) were compared with population‐based controls (n = 101) using the strengths and weaknesses of ADHD symptoms and normal‐behavior (SWAN) parent‐report questionnaire. ADHD symptomology was significantly more prevalent in SCT and already present from toddlerhood on, compared to controls. ADHD inattention symptoms were significantly increased in all karyotypes (XXX, XXY, and XYY), boys with XYY also showed significantly more hyperactivity/impulsivity symptoms than controls. Inattentiveness was more pronounced with increasing age for SCT, in contrast to controls. Within the SCT group, 24% of the children had significantly elevated ADHD symptoms at a clinical level. Already from an early age on, SCT is associated with a risk for ADHD, suggesting that its neurodevelopmental risk lies anchored in early brain maturation. Studying this genetically vulnerable population allows for the prospective study of risk markers to facilitate early and preventive interventions.
Activating Room‐Temperature Phosphorescence of Organic Luminophores via External Heavy‐Atom Effect and Rigidity of Ionic Polymer Matrix**

Published: July 2021

AbstractPure organic room‐temperature phosphorescence (RTP) materials have attracted wide attention for their easy preparation, low toxicity, and applications in various fields like bioimaging and anti‐counterfeiting. Developing phosphorescent systems with more universality and less difficulty in synthesis has long been the pursuit of materials scientists. By employing a polymeric quaternary ammonium salt with an ionic bonding matrix and heavy atoms, commercial fluorescent dyes are directly endowed with phosphorescence emission. In a single amorphous polymer, the external heavy‐atom effect generates excited triplet states and the rigid polymer matrix stabilizes them. This study put forward a new general strategy to design and develop pure organic RTP materials starting from existing library of organic dyes without complicated chemical synthesis.
