The study was conducted to investigate the potential of Parkia biglobosa fruit pulp as substrate for citric acid production by Aspergillus niger. Reducing sugar was estimated by 3,5-dinitrosalicylic acid and citric acid was estimated spectrophotometrically using pyridine-acetic anhydride methods. The studies revealed that production parameters (pH, inoculum size, substrate concentration, incuba...

The DNSA assay has been widely employed for the in vitro detection and quantification of alpha-amylase inhibitory activity. However, conventional method is associated with inconsistencies between protocols requires a large volume samples other reagents that can compromise accurate quantitation. Therefore, study aimed to develop reliable, simple, rapid analytical determining α-amylase developed ...

We studied the fate of Nissl-stained dark neurons (N-DNs) following traumatic brain injury (TBI). N-DNs were investigated in the cerebral neocortex and the hippocampus using a rat lateral Xuid percussion injury model. Nissl stain, acid fuchsin stain and immunohistochemistry with phosphorylated extracellular signal-regulated protein kinase (pERK) antibody were used in order to assess posttraumat...

A novel amino acid ionic liquid (AAIL) with L-ornithine (L-Orn) as anion was successfully synthesized, and subsequently applied as an available chiral ligand coordinated with Zn(II) in a chiral ligand exchange capillary electrophoresis (CLE-CE) system for the enantioseparation of dansyl amino acids (Dns-D,L-AAs). The influence of key parameters, such as buffer pH, concentration ratio of Zn(II) ...

Abstract Two new Zn( ii ) coordination complexes [Zn(L)(dna)(H 2 O)] ( 1 and [Zn(L)(glu)] ·H O (L = 2-(4-fluorophenyl)-1 H -imidazo[4,5- f ][1,10]phenanthroline, dna 3,5-dinitrosalicylic acid, glu glutaric acid) have been hydrothermally synthesized characterized by single crystal X-ray diffraction, elemental analysis, fluorescence spectrum, infrared spectroscopy. For complex , the 2− anion adop...
