Pharmacological interventions for the prevention of bleeding in people undergoing elective hip or knee surgery: a systematic review and network meta‐analysis [PDF]

open access: yes, 2019
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To determine the relative efficacy of pharmacological interventions for preventing blood loss in elective primary or revision hip or knee replacement, and to identify

Indigenous amino acids in primitive CR meteorites [PDF]

open access: yesarXiv, 2008
CR meteorites are among the most primitive meteorites. In this paper, we report the first measurements of amino acids in Antarctic CR meteorites, two of which show the highest amino acid concentrations ever found in a chondrite. EET92042, GRA95229 and GRO95577 were analyzed for their amino acid content using high performance liquid chromatography with ...

Attempts to Green the Synthesis of Liquid Crystals [PDF]

open access: yes, 2015
This study presents several green approaches to the synthesis of liquid crystals. In the research, three types of reactions (esterification, Suzuki cross-coupling and amidation) have been considered.

Amino acid metabolism conflicts with protein diversity [PDF]

open access: yesarXiv, 2014
The twenty protein coding amino acids are found in proteomes with different relative abundances. The most abundant amino acid, leucine, is nearly an order of magnitude more prevalent than the least abundant amino acid, cysteine. Amino acid metabolic costs differ similarly, constraining their incorporation into proteins.

Miniaturised control of acidity in multiplexed microreactors [PDF]

open access: yesarXiv, 2019
The control of acidity influences the structural assembly of biopolymers that are essential for a wide range of applications. Its miniaturization can increase the speed and the possibilities of combinatorial throughput for their manipulation, similarly to the way that the miniaturization of transistors allows the high throughput of logical operations ...
