Analogues of 1D-Myo-inositol 1,2,6-trisphosphate. Preparation of carboxymethyl and 2-hydroxyethyl phosphate derivatives

Acylation of 1D-myo-inositol 1,2,6-trisphosphate (α-trinositol) followed by alkylation of the phosphate groups with benzyl bromoacetate or 2-benzyloxyethyl iodide and deprotection provides a route to analogues with modified phosphate groups. The modifications made alter steric and ionisation properties but the possibility to participate in hydrogen bonding and ionic interaction is retained.

Application of the arbuzov reaction for the synthesis of phosphonate analogues of myo-inositol 1,2-bis- and 1,2,6-trisphosphates and methyl α-D-mannopyranoside 2,3,4-trisphosphate

The reaction of perbenzylated (±)-myo-inositol 1,2-bis- and 1,2,6-tris-phosphites with benzyl bromoacetate, followed by catalytic (Pd/C) hydrogenolysis affords (±)-myo-inositol 1,2-bis- and 1,2,6-tris(carboxymethylphosphonate). The same procedure is used for the synthesis methyl α-D-mannopyranoside 2,3,4-tris(carboxymethylphosphonate).

Synthesis of α-trinositol related analogues. Structure-activity (analgesic and anti-inflammatory) relationships

α-Trinositol analogues, including methyl ethers, deoxy, oxa and aza derivatives were prepared. The parent compound possesses weak analgesic and anti-inflammatory properties. Removal of the non-phosphorylated hydroxyls generates a compound devoid of analgesic activity but which retains the anti-inflammatory property of the parent compound. The protection of these hydroxyls as methyl ethers lends to

Facilitating an encounter with a new sexuality discourse : The role of civic communicators in building sexual health literacy among newly arrived migrants

Language and different sexual health discourses constitute barriers to the uptake of information on sexual and reproductive health and rights among migrants. Challenges remain with regards to the design and implementation of culturally appropriate programmes and interventions. This study explored the role of civic communicators in increasing access to sexual health information among migrants reset

Benzylidene protected bis-MPA : A convenient dendrimer building block

Benzylidene protected bis-MPA, 2,2-bis(hydroxymethyl)propanoic acid, was synthesised and evaluated as building block in the construction of dendrimers. It was found that the anhydride of benzylidene protected bis-MPA reacts with neopentylic alcohols to give high yields of acylated products. Purification is facilitated by the crystalline nature of most ester products. Deprotection by hydrogenolysis

A novel processing aid for polymer extrusion : Rheology and processing of polyethylene and hyperbranched polymer blends

The use of hyperbranched polymers (HBPs) as a processing aid for linear low density polyethylene (LLDPE) was investigated. Various generation (or pseudo-generation) HBPs were used which had either 16 carbon atom alkanes or a mixture of 20/22 carbon atom alkanes on the end groups. In addition, the degree of end group substitution was studied. Blends of up to 10% HBP content were mixed via extrusion

Material affordances in circular products and business model development : for a relational understanding of human and material agency

This paper uses the notion of material affordances to show that a focus on how people engage with materials helps understanding how organizations transit toward sustainability. Material affordances refer to the enablements and constraints afforded by materials to someone engaging with an environment for a particular purpose. Based on a qualitative study of a company's efforts at becoming circular,

Understanding sexual health literacy, gender egalitarian perspectives, and access to SRHR-care among migrants in Sweden

Improving access to SRHR-information and care among refugees and migrants remain a central issue. Countries with strong integration policies have significant reductions in the inequities in sexual and reproductive health outcomes. Securing access to SRHR is linked to the extent to which gender equality is fulfilled, including equal rights for men and women to learn the language and participate in

Integration Impossible? Ethnic Nationalism and Refugee Integration in Bulgaria

In the past several years many Western European countries have introduced stricter entry regimes both for third-country nationals, as well as for asylum-seekers and refugees. More recently, since the mixed migratory influx of 2015, the figure of the foreigner has become more and more visible on a national level sparking debates on the future of the European Union (EU), European and national identi

Hyperglycaemia-associated Caspase-3 predicts diabetes and coronary artery disease events

BACKGROUND: Apoptosis is central in both diabetes and atherosclerosis, linked to pancreatic beta cell death and plaque progression. Circulating Caspase-3 has also been associated with diabetes and coronary calcium score. Here, we explored if soluble Caspase-3 (sCaspase-3) is associated with cardio-metabolic risk factors and predicts incidence of diabetes and coronary artery disease (CAD).METHODS:

Unruly voices: exploring employee voice in the context of ethical resistance

Despite the growing interest in employee voice, real opportunities for co-workers to challenge the status quo are limited (Kenny et al., 2020; Wilkinson et al., 2018; de Maria, 2008). This conceptual paper explores the unruly dimension of employee voice in connection to whistleblowing and protest as modes of ethical resistance (de Maria, 2008). It partly follows recent attempts inorganisation stud

Bifidobacterium species associated with breastfeeding produce aromatic lactic acids in the infant gut

Breastfeeding profoundly shapes the infant gut microbiota, which is critical for early life immune development, and the gut microbiota can impact host physiology in various ways, such as through the production of metabolites. However, few breastmilk-dependent microbial metabolites mediating host–microbiota interactions are currently known. Here, we demonstrate that breastmilk-promoted Bifidobacter

"To be seen" - older adults and their relatives' care experiences given by a geriatric mobile team (GerMoT)

BACKGROUND: The proportion of older people in the population has increased globally and has thus become a challenge in health and social care. There is good evidence that care based on comprehensive geriatric assessment (CGA) is superior to the usual care found in acute hospital settings; however, the evidence is scarcer in community-dwelling older people. This study is a secondary outcome of a ra
