Regulatory signaling pathways in hematopoietic stem cell development.

The blood system provides the body with oxygen and nutrients, maintains the homeostasis of the internal environment through material exchange, and keeps the body with immune defense and protection. Hematopoietic stem cells (HSCs), which are pluripotent adult stem cells with self-renewal and differentiation potential, are the origin of mature blood cells in the body. The production, development and maturation processes of HSCs and their derivatives are the so-called 'hematopoiesis', which begins in the early embryonic development and throughout the life course; any abnormality during these processes can cause the occurrence of hematological diseases. Therefore, a deeper understanding of hematopoietic development and its regulation is important to the diagnosis and treatment of blood diseases. In recent years, a series of advances have been made in studying hematopoietic development using mice and zebrafish as animal models. It has been shown that BMP, Notch and Wnt signaling pathways play an important role in the fate determination and generation of HSCs. In this review, we systematically summarize the regulatory roles of these signaling pathways in the hematopoietic process of mice and zebrafish embryos, to improve our understanding on the underlying regulatory network of hematopoietic development and provide guidance for clinical application.

In-hospital process for viral hepatitis C screening and management in China (Draft)

Viral hepatitis C is one of the important causes of liver cirrhosis and hepatocellular carcinoma. There are approximately 10 million cases of chronic hepatitis C virus (HCV) infection in China. However, over 70% of HCV infections of China have not yet been detected. According to the goal of "eliminating viral hepatitis as a public health threat by 2030" of the World Health Organization Viral Hepatitis Strategy, and the fact that medical institutions remain the main places for detecting HCV infections or patients in China at present, we established the " In-hospital process for viral hepatitis C screening and management in China (Draft)", with intention to promote the multidisciplinary collaboration and cooperation among the departments of clinic, laboratory, infection control, management, and etc. in medical institutions, and strengthen consultation and referral of patients with detected HCV antibodies and advance the diagnosis and antiviral treatment of patients with chronic hepatitis C.

Optimization of CUT&Tag product recovery and library construction method.

The emerging cleavage under target and tagment (CUT&Tag) technology uses Tn5 transposase to cleavage near the DNA binding site of target protein and study the generated DNA fragments by the next-generation sequencing. It can quickly identify protein-DNA interactions, which greatly simplifies the experimental process of ChIP-Seq. After CUT&Tag tagment reaction, DNA recovery or other post-processing is required to perform library construction PCR. Different recovery methods have significant impact respectively. By establishing Streptavidin beads recovery CUT&Tag(srCUT&Tag), we can quickly and conveniently complete the product recovery of CUT&Tag. We carried out CUT&Tag assay of H3K4me3, RNA Polymerase II (RNA polymerase II, RNAPII), transcription factor CTCF and HMGA1 in K562 cells with different recovery methods, including ethanol precipitation, fragment separation magnetic beads (SPRI) Magnetic bead recovery, direct PCR method, as well as our srCUT&Tag recovery method. The results show that among the CUT&Tag results of four different targets, the SPRI magnetic bead recovery and our srCUT&Tag methods have higher recovery efficiency than the direct PCR method and ethanol precipitation method. All CUT&Tag results showed that the recovery of SPRI magnetic beads would lose most of the product fragments less than 150 bp. In the recovery of CTCF and HMGA1, direct PCR lost most of the fragments larger than 300 bp and has significant difference from result of other recovery method. This enables srCUT&Tag to provide more real and higher-resolution information than other recovery method. In summary, the newly established srCUT&Tag recovery method can improve the efficiency of CUT&Tag library construction and obtain better data quality compared with the existing CUT&Tag product recovery method, providing a better technical choice for epigenetics research.

Diabetoporosis: Role of nitric oxide.

Diabetoporosis, diabetic-related decreased bone quality and quantity, is one of the leading causes of osteoporotic fractures in subjects with type 2 diabetes (T2D). This is associated with lower trabecular and cortical bone quality, lower bone turnover rates, lower rates of bone healing, and abnormal posttranslational modifications of collagen. Decreased nitric oxide (NO) bioavailability has been reported within the bones of T2D patients and can be considered as one of the primary mechanisms by which diabetoporosis is manifested. NO donors increase trabecular and cortical bone quality, increase the rate of bone formation, accelerate the bone healing process, delay osteoporosis, and decrease osteoporotic fractures in T2D patients, suggesting the potential therapeutic implication of NO-based interventions. NO is produced in the osteoblast and osteoclast cells by three isoforms of NO synthase (NOS) enzymes. In this review, the roles of NO in bone remodeling in the normal and diabetic states are discussed. Also, the favorable effects of low physiological levels of NO produced by endothelial NOS (eNOS) versus detrimental effects of high pathological levels of NO produced by inducible NOS (iNOS) in diabetoporosis are summarized. Available data indicates decreased bone NO bioavailability in T2D and decreased expression of eNOS, and increased expression and activity of iNOS. NO donors can be considered novel therapeutic agents in diabetoporosis.

The Temperature Role in the Manufacturing of an Electrode for Supercapacitors with Carbon Black and Graphene Oxide

Supercapacitors (SCs) are energy storage devices with a growing interest thanks to their high-power charge and discharge process and long-cycle life. Their main drawback, when compared to more common devices such as batteries, consists in a low energy density. The performances of SCs can however be improved with the coupling of additives to the main active material, which usually is an Activated Carbon. The most common additive is instead Carbon Black (CB), while more recently also Graphene-derived materials have been successfully exploited for this purpose, as the reduced Graphene Oxide (rGO). However, besides raw materials choice, details related to the manufacturing have a leading importance in the attempt to obtain novel active materials with an industrial-ready process which also looks toward the needs of more environmental friendly and economically convenient solutions. In this work, a physical-chemical analysis is performed to show temperature effects on CB, GO and on a CB/GO water-based slurry with helpful results about GO reduction and CB/GO nanocomposite formation.

Production and Comparative Physicochemical Analysis of Vinegar from Locally Grown Fruits in Nigeria and Industrial Produced Vinegar

Vinegar is the product made from the conversion of ethyl alcohol to acetic acid by a genus of bacteria, Acetobacter. The major aim of the work is to produce a vinegar with locally made fruits and compare it with the industrial produced vinegar to ascertain if it can be used to substitute the industrial produced vinegar and to also determine if there are presence of acetic acid bacteria present in the vinegar which can be used as inoculants for future fermentation the sensory attributes were also analysed to determine the consumer acceptability of the vinegar produced. This work involves production of vinegar from locally produced fruits in Nigeria by homemade scale process and then analyzing the vinegar to determine the physicochemical components of the vinegar as well as identifying the acetic acid bacteria present in the vinegar and its sensory attributes. The vinegar produced was analysed for its pH, relative density and titrable acidity and from the result, there was no significant difference in the pH and relative density of the vinegars. The titrable acidity of the industrial produced vinegar is higher than the locally produced vinegars analysed. The microbial isolation of the vinegar for safety assessment gave no growths in the media used for the analysis which means that there are no pathogenic organisms like mould or coliform which can cause diseases to the consumers. The major organism isolated was the Acetobacter spp. although the culture independent methods should be carried out to determine other non culturable organisms present in the vinegar. The sensory evaluation shows that the locally produced was well accepted from the scores on the result presented. Generally, the result of this work shows that indeed vinegar of good quality can be produced locally using locally grown fruits but optimization of the process should be carried out to improve yield.

Low-Contact Co-Design: Considering more flexible spatiotemporal models for the co-design workshop

The recent global experience of COVID-19 has problematized the face-to-face co-design process and forced co-design researchers and practitioners to rethink the process of collaboration that typically takes place in a co-design workshop. This paper considers how we might continue to co-design when physical proximity is not possible. Recognising that technology has long played a role in co-design practice, we argue that to date, the technologically mediated experience of co-design has been largely based on the assumption of replicating the physical and embodied experience of the co-design workshop. Rather than accepting the deficit culture implied through the curtailing of much of the conventional face-to-face activities we associate with co-design, this paper reports on proactive research into novel possibilities for continuing collaborative research work through the concept of ‘low-contact co-design’. A series of proprietary visual models that explore a range of spatiotemporal conditions within which co-design practices can occur are presented. Opportunities for engaging with new communities, and in new processes are highlighted and a spatiotemporal framework for planning co-design processes is presented.

Design for Sustainability Transformations: A Deep Leverage Points Research Agenda for the (Post-)Pandemic Context

This position paper presents a prototype research agenda for design for sustainability transformations (DfST) in the (post-)pandemic context. COVID-19 has made visible vulnerabilities, structural dysfunctions, inequalities and injustices across health, environmental, social, economic, provisional and political systems. In response to the crisis, rapid, adaptive, technological and social innovations have started to emerge across all levels of society, opening up a multiplicity of alternative futures. This is an opportune time to address long-standing and urgent sustainability challenges in ways that move beyond the ineffective and business-as-usual approaches of ecological modernism. The authors used a co-creative process to identify weak signals relevant to sustainability transformations. In alignment with the deep leverage points framework, the identified weak signals are presented under two main headings: first, social structures and institutions; and second, values, goals and worldviews. The deep leverage points form the basis of a research agenda on how DfST could contribute to sustainability transformations right now and in the longer-term.
