Expanding the scope of methyl xanthate esters - From Barton-McCombie reaction auxiliary to versatile protective group

The methyl xanthate ester is presented as a versatile protective group for alcohols. Hydroxyl groups can easily be transformed into methyl xanthate esters by several methods and are commonly used as an auxiliary in the Barton-McCombie reaction. We show that these methyl xanthate esters can readily and chemoselectively be cleaved under mild conditions by the action of diethylenetriamine using micro

Teaching Assembly by Demonstration Using Advanced Human Robot Interaction and a Knowledge Integration Framework

Conventional industrial robots are heavily dependent on hard automation that requires pre-specified fixtures and time-consuming (re)programming performed by experienced operators. In this work, teaching by human-only demonstration is used for reducing required time and expertise to setup a robotized assembly station. This is achieved by the proposed framework enhancing the robotic system with adva

Design for resource-limited societies : Informational behaviour of designers

There is a sharp contrast between High Resource Settings (HRSs), commonly seen in developed countries and Low Resource Settings (LRSs), typically found in the marginalised sections of societies around the world. Product design for LRSs is crucial to satisfy unmet or under-served needs of the people living in LRSs. Supporting designers to develop successful products for LRSs demands developing an i

Improved molecular recognition of Carbonic Anhydrase IX by polypeptide conjugation to acetazolamide

The small molecule inhibitor acetazolamide (AZM) was conjugated to a set of designed polypeptides and the resulting conjugates were evaluated for their affinity to Human Carbonic Anhydrase II (HCA II) using surface plasmon resonance. The dissociation constant of the AZM-HCA II complex was 38. nM and that of the AZM conjugated polypeptide (4-C10L17-AZM) to HCA II was found to be 4. nM, an affinity

4-Hydroxy-N -[3,5-bis(trifluoromethyl)phenyl]-1,2,5-thiadiazole-3-carboxamide: A novel inhibitor of the canonical NF-κB cascade

The NF-κB signaling pathway is a validated oncological target. Here, we applied scaffold hopping to IMD-0354, a presumed IKKβ inhibitor, and identified 4-hydroxy-N-[3,5-bis(trifluoromethyl)phenyl]-1,2,5-thiadiazole-3-carboxamide (4) as a nM-inhibitor of the NF-κB pathway. However, both 4 and IMD-0354, being potent inhibitors of the canonical NF-κB pathway, were found to be inactive in human IKKβ e

Numerical analysis of radiative heat transfer in an inhomogeneous and non-isothermal combustion system considering H2O/CO2/CO and soot

Purpose - H2O, CO2 and CO are three main species in combustion systems which have high volume fractions. In addition, soot has strong absorption in the infrared band. Thus, H2O, CO2, CO and soot may take important roles in radiative heat transfer. To provide calculations with high accuracy, all of the participating media should be considered non-gray media. Thus, the purpose of this paper is to st

Sustainable management of cassava processing waste for promoting rural development

Cassava is the third-most important food source in the tropics after rice and maize. Cassava is the staple food for about half a billion people in the World. It is a tropical crop grown mainly in Africa, Asia, and South America. It can be cultivated on arid and semiarid land where other crops do not thrive. During the processing of cassava into chips, flour or starch, enormous amount of wastes are

IAP-Based Cell Sorting Results in Homogeneous Transplantable Dopaminergic Precursor Cells Derived from Human Pluripotent Stem Cells

Human pluripotent stem cell (hPSC)-derived mesencephalic dopaminergic (mesDA) neurons can relieve motor deficits in animal models of Parkinson's disease (PD). Clinical translation of differentiation protocols requires standardization of production procedures, and surface-marker-based cell sorting is considered instrumental for reproducible generation of defined cell products. Here, we demonstrate

Optimum design of distributed energy hubs using hybrid surrogate models (HSM)

The energy hub concept is gradually getting popular due to its capability to integrate renewable energy technologies into the energy grid with a minimum impact. Designing distributed energy hubs is a challenging task due to the coupling of optimum dispatch and energy system sizing problems. Operation of the system needs to be considered for 8760 time steps and energy system sizing optimization can

Mitochondria chaperone GRP75 moonlighting as a cell cycle controller to derail endocytosis provides an opportunity for nanomicrosphere intracellular delivery

Understanding how cancer cells regulate endocytosis during the cell cycle could lead us to capitalize this event pharmacologically. Although certain endocytosis pathways are attenuated during mitosis, the endocytosis shift and regulation during the cell cycle have not been well clarified. The conventional concept of glucose-regulated proteins (GRPs) as protein folding chaperones was updated by dis

Asthma referrals : A key component of asthma management that needs to be addressed

Heterogeneity of asthma and difficulty in achieving optimal control are the major challenges in the management of asthma. To help attain the best possible clinical outcomes in patients with asthma, several guidelines provide recommendations for patients who will require a referral to a specialist. Such referrals can help in clearing the uncertainty from the initial diagnosis, provide tailored trea

Adjustable mini-sling compared with conventional mid-urethral slings in women with urinary incontinence. A randomized controlled trial

Introduction: The primary aim of this study was to compare the objective and subjective outcomes and short-term complication rates of an adjustable single-incision mini-sling (SIMS) vs. standard mid-urethral slings (SMUS). The secondary aim was to report pain perception and complications at the one-year follow up. Material and methods: The study was designed as a multicenter prospective randomized

Parenting and parenting support in Germany and Sweden: Convergence and persistent dissimilarities

Parenting support constitutes a long-established part of both the Swedish and the German portfolio of public social services. It originated in the 1920s in Germany, the 1930s in Sweden. Support measures and underlying philosophies have steadily changed in both countries, thereafter. The 1990s saw a new ‘turn to parenting’ and also new measures in Sweden and Germany. In this article, we ask how par„Parenting“ und „Parenting Support“ in Deutschland und Schweden. Konvergenz und fortdauernde Unterschiede.

Fluorescence microscopy of nanochannel-confined DNA

Stretching of DNA in nanoscale confinement allows for several important studies. The genetic contents of the DNA can be visualized on the single DNA molecule level and both the polymer physics of confined DNA and also DNA/protein and other DNA/DNA-binding molecule interactions can be explored. This chapter describes the basic steps to fabricate the nanostructures, perform the experiments and analy

New Social Risk Policies for German and Swedish Families

Until very recently, Germany belonged to the ‘familialist’ group of welfare states, which offered cash rather than services to married couples and families. Sweden, in contrast, belonged to the ‘non-familialist’ counterpart, fostering gender equality in employment and family care via public services and extended reconciliation measures for decades. During the 2000s, however, Germany eventually enaAbstractUntil very recently, Germany belonged to the ‘familialist’ group of welfare states, which offered cash rather than services to married couples and families.

Increased CXCL8 expression is negatively correlated with the overall survival of patients with ER-negative breast cancer

Background: C-X-C motif chemokine ligand 8 (CXCL8) is a multi-functional chemokine and has important roles during tumor formation and development. It was previously reported that increased CXCL8 protein levels occurred in certain patients. Materials and Methods: In the present study, we examined levels of CXCL8 mRNA in breast cancer tissues and analyzed its levels in correlation to patients' clini
