Article Abstract
Covering: January 2000 to July 2018 gem-Dimethylcyclobutanes are a common motif found in a multitude of natural products, and thus these structures have captivated synthetic chemists for years. However, until the turn of the century, most synthetic efforts relied upon the use of widely available terpenes, such as pinene or caryophyllene, that already contain the gem-dimethylcyclobutane motif. This approach limits the scope of molecules that can be accessed readily. This review highlights recent syntheses in which the gem-dimethylcyclobutane is assembled via de novo approaches. An outlook on the future of this research area is also provided.
Brucellosis remains an endemic disease in livestock populations in Rwanda, but the prevalence of the disease varies by geographic region. The common use of informal milk marketing channels represents a health hazard to humans when milk from Brucella-infected cows from one or more households is mixed with milk from other households for human consumption. In Rwanda, knowledge about the burden of brucellosis in livestock and factors associated with farmers' choice of milk marketing channels is very limited.

Ice formation from water vapor is a common phenomenon with significant implications for both natural ice formation and industrial processes. However, there remains controversy over how deposition frequency and substrate temperature affect the structural forms of deposition products and their formation processes. In this study, we employed molecular dynamics simulations to investigate the deposition process of water vapor onto a cold Au(001) substrate at different temperatures and deposition frequencies.

Industrial biotechnology employs cells for producing valuable products and serving as biocatalysts sustainably, addressing resource, energy, and environmental issues. is a preferred host for creating microbial chassis cells and producing industrial enzymes and functional nutritional products. In this study, a dual-module T7 integration expression system in was established.
In the present investigation, 13% ± 0.84 of the extracted and purified phycocyanin from Phormidium versicolor was obtained, with a purity of 0.69 following dialysis.
Spasmodic dysphonia (SD) is now generally considered to be a task-specific focal dystonia. For the first time, we wanted to explore the relationship between SD and dystonia from a combined neurological and phoniatric perspective. For this, we studied 115 patients with non-psychogenic SD by a combined neurological and phoniatric evaluation.
