Publication date: Available online 19 October 2019Source: Biological ControlAuthor(s): Qiya Yang, Junwei Diao, Dhanasekaran Solairaj, Ngolong Ngea Guillaume Legrand, Hongyin ZhangAbstractThe present study investigated the effect of ascorbic acid (Vitamin C, VC) at 250μg/mL in the enhancement of biocontrol efficacy of Pichia caribbica against blue mold decay caused by Penicillium expansum on apples. Compared to the performance of the yeast without treatment, P. caribbica induced by 250 μg/mL of VC potentially enhanced biocontrol activity against P. expansum and high growth rate on the apple surface when stored at 20°C and 4°C. The mechanisms underlying this improvement in biocontrol efficiency were probed by investigating the protein expression profile and transcriptome characterization of P. caribbica induced by VC. From the proteomics results, 46 proteins were identified as differentially expressed proteins (DEPs), among them 18 proteins were up-regulated and 28 proteins were significantly down-regulated. These up-regulated DEPs including glyceraldehyde-3-phosphate dehydrogenase and alcohol dehydrogenase were associated with the glucose metabolism. From the transcriptomic analysis, 292 genes were found to be differentially expressed genes (DEGs), among them 137 genes were up-regulated and 155 genes were down-regulated. These up-regulated genes were involved in pyruvate metabolism, amino sugar and nucleotide sugar metabolism. These molecular studies suggest that...

ConclusionWithin the limitations of the study, GBR with or without autogenous block graft may be an effective approach in augmenting horizontally deficient mandibular or maxillary ridges, before the placement of dental implants. However, more complications may be seen with the use of an autogenous block graft related to the donor sites.

While recreational marijuana is legal in 11 states as of November 2019, more states gravitating toward legalizing the recreational use of the substance, and 33 states allowing medical marijuana, there’s apparently no stopping this trend. Cannabis, in the form of marijuana, hemp, and cannabidiol (CBD)  is being used for pain relief, to alleviate stress, cope with anxiety, and a number of other mental health disorders and addictions. Yet, there’s a dearth of clinical studies that have been conducted on the overall effects on a user’s health. Clearly, as Crain’s Detroit Business points out, more ...

The exhaustible character of the fossil resources linked to the increase of plastic residues in the environment encourages an intensive research on biorenewable and biodegradable polymers to synthesize new materials. Taking into account this current scenario, this work searches for new green routes to elaborate physical hydrogels...

The influence of catalyst preparation conditions on the synthesis of NiOx(OH)y was studied. A series of batch experiments were carried out to verify the effective conversion...
