Influence of Thickener and Mineral Supplementation of Bleaching Gels on Enamel Demineralization

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study evaluated the effect of the type of thickener and mineral supplementation of bleaching gels on enamel demineralization. Materials and Methods Enamel specimens were divided into five groups according to the type of thickener: CA‐Carbopol, AE‐Aerosil 200, PO‐Poloxamer 407, GG‐Guar gum, and HEC‐Hydroxyethyl cellulose.

The Pathology and Blood Biochemistry of Juvenile Lates calcarifer on Diets Contaminated With Mycotoxins, Histamines and Rancid Fats—A Case Study

Journal of Fish Diseases, EarlyView.
ABSTRACT Mycotoxins, originating from contaminated raw materials or suboptimal feed storage, are a growing concern in tropical aquaculture. Common fungi such as Aspergillus spp. and Fusarium spp. produce mycotoxins including aflatoxin, fumonisin, deoxynivalenol and zearalenone. High doses or prolonged exposure (weeks) to low doses of these mycotoxins (<

Genome‐Wide Analysis of DtxR and HrrA Regulons Reveals Novel Targets and a High Level of Interconnectivity Between Iron and Heme Regulatory Networks in Corynebacterium glutamicum

Molecular Microbiology, EarlyView.
Iron is essential for life, yet excessive levels can quickly lead to cellular damage via oxidative stress, underscoring the need for global regulators of iron and heme homeostasis. In this study, we present a genome‐wide analysis of the binding patterns of DtxR and HrrA in Corynebacterium glutamicum.

Molecular changes in agroinfiltrated leaves of Nicotiana benthamiana expressing suppressor of silencing P19 and coronavirus‐like particles

Plant Biotechnology Journal, EarlyView.
Summary The production of coronavirus disease 2019 vaccines can be achieved by transient expression of the spike (S) protein of severe acute respiratory syndrome coronavirus 2 in agroinfiltrated leaves of Nicotiana benthamiana. Relying on bacterial vector Agrobacterium tumefaciens, this process is favoured by co‐expression of viral silencing suppressor

OsDUF2488 acts synergistically with OsPrx1.1, regulates ROS metabolism and promotes dehydration tolerance in rice

Plant Biotechnology Journal, EarlyView.
Summary Stress‐mediated regulation of energy metabolism and its relation to plant adaptation remain largely unknown. Mitochondrial redox potential is greatly influenced by stress‐induced reactive oxygen species (ROS); therefore, we mapped the dehydration‐induced alterations in the mitochondrial proteome of a resilient rice cultivar, Rasi, generating a ...
