High-resolution crystal structure of the double nitrate hydrate [La(NO3)6]2[Ni(H2O)6]3 · 6H2O
This study introduces bis[hexakis(nitrato- κ 2O,O ′ )lanthanum(III)] tris[hexaaquanickel(II)] hexahydrate, [La(NO3)6]2[Ni(H2O)6]3 · 6H2O, with a structure refined in the hexagonal space group R\overline{3}. The salt comprises [La(NO3)6]3 − icosahedra and [Ni(H2O)6]2+ octahedra, thus forming an intricate network of interpenetrating honeycomb lattices arranged in layers. This arrangement is stabilized through strong hydrogen bonds. Two successive layers are connected via the second [Ni(H2O)6]2+ octahedra, forming sheets which are stacked perpendicular to the c axis and held in the crystal by van der Waals forces. The s...

High-pressure intrusion of double salt aqueous solution in pure silica chabazite: searching for cation selectivity
Heterogeneous lyophobic systems (HLSs), i.e. systems composed of a nanoporous solid and a non-wetting liquid, have attracted much attention as promising candidates for innovative mechanical energy storage and dissipation devices. In this work, a new HLS based on a pure silica chabazite (Si-CHA) and a ternary electrolyte solution (KCl + CaCl2) is studied from porosimetric and crystallographic points of view. The combined approach of this study has been fundamental in unravelling the properties of the system. The porosimetric experiments allowed the determination of the energetic behaviour, while high-pressure in sit...

Preeclamptic heart failure — perioperative concerns and management: a narrative review
This article reviews the current evidence base regarding preeclamptic heart failure and its pathophysiology, types, and clinical features. We also describe the medical and anesthetic management of these patients during the peripartum period. Heart failure due to preeclampsia can present as either systolic or diastolic dysfunction. The management strategies of systolic heart failure include dietary salt restriction, diuresis, and cautious use of beta-blockers and vasodilators. Diuretics are the mainstay in the treatment of diastolic heart failure. In the absence of obstetric indications, vaginal delivery is the safest mode ...

Instigation of neurosporaxanthin from < em > Rhodococcus ruber < /em > O16N isolated from Gulf of Khambhat
We present the maiden study on the production of neurosporaxanthin, a carotenoid, from marine Rhodococcus ruber O16N. Analysing various physical parameters including carbon source, agitation speed, temperature, salt and pH, we found that agitation adversely affects biomass and carotenoid production. Isolate O16N grew well, when medium was supplemented with mannitol or sorbitol, CaCl2, at pH 6 and best carotenoid production was observed when sorbitol or fructose and CaCl2 was supplemented in media at pH 7 at 37 °C in static condition with the maximum carotenoid yield of 1097 mg/L, whopping 18-fold more as compared to nutri...

Enhancing the stability and therapeutic potential of the antimicrobial peptide Feleucin-K3 against Multidrug-Resistant a. Baumannii through rational utilization of a D-amino acid substitution strategy
Biochem Pharmacol. 2024 May 7:116269. doi: 10.1016/j.bcp.2024.116269. Online ahead of print.ABSTRACTAntimicrobial peptides (AMPs), which have a low probability of developing resistance, are considered the most promising antimicrobial agents for combating antibiotic resistance. Feleucin-K3 is an amphiphilic cationic AMP that exhibits broad-spectrum antimicrobial activity. In our previous research, the first phenylalanine residue was identified as the critical position affecting its biological activity. Here, a series of Feleucin-K3 analogs containing hydrophobic D-amino acids were developed, leveraging the low sensitivity o...

asery
1-(3-aryl)-3-(dimethylamino)prop-2-en-1-one (enaminones) derivatives and the diazonium salt of para-chloroaniline were used to synthesize several novel disperse azo dyes with high yield and the use of an environmentally friendly approach. At 100 and 130 &deg;C, we dyed polyester fabrics using the new synthesized disperse dyes. At various temperatures, the dyed fabrics&rsquo; color intensity was assessed. The results we obtained showed that dyeing utilizing a high temperature method at 130 &deg;C was enhanced than dyeing utilizing a low temperature method at 100 &deg;C. Reusing dye ...
