Reactions of [RuCp*Cl2]2 with dibenzoylmethane and triethylamine, in either dichloromethane or toluene, produced the complexes [RuCl(η(6)-C5Me4CH2)(PhCOCCOPh)] (1) and [RuCl3(η(6)-C5Me4CH2)][RuCp*(C6H5CH3)] (2) respectively under mild conditions. Both compounds 1 and 2 are examples of an unusual tetramethylfulvene-ruthenium structure, obtained by deprotonation of the pentamethylcyclopentadienyl ligand, and were characterised by single-crystal X-ray diffraction.

Macrophages remove apoptotic cells via phagocytosis, also known as efferocytosis, during inflammation to maintain tissue homeostasis. This process is accompanied by various metabolic changes in macrophages including the production of lipid metabolites by fatty acid oxygenases. Among these, highly reactive metabolites, called lipid-derived electrophiles (LDEs), modify cysteines and other nucleophilic amino acids in intracellular proteins.

Visceral adipose tissue, a type of abdominal adipose tissue, is highly involved in lipolysis. Because increased visceral adiposity is strongly associated with the metabolic complications related with obesity, such as type 2 diabetes and cardiovascular disease, there is a need for precise, targeted, personalized and site-specific measures clinically. Existing studies showed that ectopic fat accumulation may be characterized differently among different populations due to complex genetic architecture and non-genetic or epigenetic components, ie, Asians have more and Africans have less visceral fat vs Europeans.

Gaucher disease (GD) is a rare lysosomal disorder characterized by the accumulation of glycosphingolipids in macrophages resulting from glucocerebrosidase (GCase) deficiency. The accumulation of toxic substrates, which causes the hallmark symptoms of GD, is dependent on the extent of enzyme dysfunction. Accordingly, three distinct subtypes have been recognized, with type 1 GD (GD1) as the common and milder form, while types 2 (GD2) and 3 (GD3) are categorized as neuronopathic and severe.

Glucansucrase Dsr_Wcp3a from a Weissella confusa strain discovered in fermented maize (pozol) was produced in E. coli BL21 resulting in three truncated forms of the native enzyme. An important modification of specificity is observed, as the truncated enzymes synthesize low molecular weight dextran from sucrose, probably due to the absence of domains IV and V, compared to the native enzyme which produces high molecular weight dextran.
