“…Three-dimensional (3D) carbon nanotube (CNT)-based macrostructures have recently received extensive attention because the outstanding properties of one- and two-dimensional nanostructures, such as nanotubes and graphene, have not been successfully translated into key engineering applications. − However, experimental realization of a controlled macroscale 3D CNT architecture represents a huge challenge …”

A three-dimensional (3D) nitrogen-doped multiwall carbon nanotube (N-MWCNT) sponge possessing junctions induced by both nitrogen and sulfur was synthesized by chemical vapor deposition (CVD). The formation of "elbow" junctions as well as "welded" junctions, which are attributed to the synergistic effect of the nitrogen dopant and the sulfur promoter, plays a critically important role in the formation of 3D nanotube sponges. To the best of our knowledge, this is the first report showing the synthesis of macroscale 3D N-MWCNT sponges. Most importantly, the diameter of N-MWCNT can be simply controlled by varying the concentration of sulfur, which in turn controls both the sponge's mechanical and its electrical properties. It was experimentally shown that, with increasing diameter of N-MWCNT, the elastic modulus of the sponge increased while the electrical conductivity decreased. The mechanical behaviors of the sponges have also been quantitatively analyzed by employing strain energy function modeling.

“…We included 38 trials from the database search and 9 unpublished studies from trial registries or other methods. Ultimately, 47 RCTs (comprising 7,798 patients) (10–56) performed between 1993 and 2021 were included. Twenty-one types of vasoactive agents were compared in the included trials, including single administration of NE, EP, enoximone (EX), dopexamine (DX), dobutamine (DB), dopamine (DA), levosimendan (LE), vasopressin (VP), TP, SP, phenylephrine (PE), placebo (PA) and other catecholamines (CE), as well as combined therapies including NE plus DB (NE_DB), NE plus DX (NE_DX), NE plus EP (NE_EP), NE plus TP (NE_TP), NE plus VP (NE_VP), TP plus DB (TE_DB), and TP plus CE (TP_CE).…”

Background Septic shock is a distributive shock with decreased systemic vascular resistance and mean arterial pressure (MAP). Septic shock contributes to the most common causes of death in the intensive care unit (ICU). Current guidelines recommend the use of norepinephrine as the first-line vasopressor, while adrenergic agonists and vasopressin analogs are also commonly used by physicians. To date, very few studies have synthetically compared the effects of multiple types of vasoactive medications. The aim of this study is to systemically evaluate the efficacy of vasoactive agents both individually and in combination to treat septic shock. Methods The PubMed, MEDLINE, Embase, Web of Science and Cochrane Central Register for Controlled Trials (CENTRAL) were searched up to May 12, 2022, to identify relevant randomized controlled trials. A network meta-analysis was performed to evaluate the effect of different types of vasopressors. The primary outcome was 28-day all-cause mortality. The secondary outcome was the ICU length of stay. Adverse events are defined as any undesirable outcomes, including myocardial infarction, cardiac arrhythmia, peripheral ischemia or stroke and cerebrovascular events. Findings Thirty-three RCTs comprising 4966 patients and assessing 8 types of vasoactive treatments were included in the network meta-analysis. The surface under the cumulative ranking curve (SUCRA) provided a ranking of vasoactive medications in terms of 28-day all-cause mortality from most effective to least effective: norepinephrine plus dobutamine, epinephrine, vasopressin, terlipressin, norepinephrine, norepinephrine plus vasopressin, dopamine and dobutamine. Dopamine was associated with a significantly shorter ICU stay than norepinephrine, terlipressin and vasopressin, while other vasoactive medications showed no definite difference in ICU length of stay. Regarding adverse events, norepinephrine was associated with the highest incidences of myocardial infarction and peripheral ischemia. Dopamine was associated with the highest incidence of cardiac arrhythmia. Epinephrine and terlipressin were associated with the highest incidences of myocardial infarction and peripheral ischemia. Interpretation The results of this network meta-analysis suggest that norepinephrine plus dobutamine is associated with a lower risk of 28-day mortality in septic shock patients than other vasoactive medications, and the use of dopamine is associated with a higher risk of 28-day mortality due to septic shock than norepinephrine, terlipressin and vasopressin.

“…In 1864 Schiff Hugo firstly reported the condensation reaction of the Primary Amine with active carbonyl compounds such as aldehydes, ketones, which generated a class of compounds with imino (Azomthine group) (-RC= N-), it was called the Schiff base. Synthesis of Schiff base is relatively easy [1][2] by flexible choicing different amine and aldehydes and ketones [3][4] . The structure of the ligand and metal complexes can open up from chain to cyclization , from single to multi-tooth gear.…”
