Development of a Colloidal Gold Immunochromatographic Assay Strip Using a Monoclonal Antibody for the Rapid Detection of Ofloxacin.

The livestock industry uses ofloxacin, an antibiotic, to prevent several animal diseases; however, the overdose of ofloxacin used in animal farming treatments may appear in food products and cause some adverse human health effects. Hence, there is an immediate need to develop a method suitable for on site large-scale detection of ofloxacin residues in animal-derived foods. This study aimed to prepare a monoclonal antibody with high sensitivity and affinity for ofloxacin by re-synthesizing the ofloxacin hapten and synthesizing the corresponding complete antigen.

Association of corneal endothelial cell morphology with neurodegeneration in mild cognitive impairment and dementia.

Introduction: Corneal confocal microscopy (CCM) detects neurodegeneration in mild cognitive impairment (MCI) and dementia and identifies subjects with MCI who develop dementia.

Kappa-carrageenan and xylooligosaccharide effect on water mobility and structural changes in silver carp proteins during frozen storage.

Background: The cryoprotective effect of xylooligosaccharide (XO) and kappa-carrageenan (KC) mixture on silver carp proteins in fluctuated frozen storage from 4 to -18 °C was analyzed. Positive control as a conventional cryoprotectant mixture of sucrose (4%) and sorbitol (4%), KC (3%) and XO/KC (3%) treatments were incorporated in silver carp surimi and myofibrillar proteins to analyze the water mobility and its influence on structural attributes.

Results: The temperature fluctuation significantly increased the structural alteration in samples with no treatments due to oxidative changes, protein denaturation and recrystallization.

Sustained corneal nerve loss predicts the development of diabetic neuropathy in type 2 diabetes.
