BACKGROUND Sweet potato often suffers mechanical damage during harvest, handling, and transportation. Infections, water loss, and quality changes of sweet potato caused by mechanical damage pose great financial losses. Wound healing is an effective method to alleviate such problems. In this study, the effects of postharvest treatment with benzothiazole (BTH) on wound healing of sweet potato was investigated. RESULTS Postharvest BTH treatment of sweet potatoes promoted lignin accumulation in wounded tissues, and 100 mg L-1 BTH exhibited better effects than 50 mg L-1 or 150 mg L-1 BTH. The biosynthesis of lignin in wounded tissues significantly decreased the weight loss of sweet potatoes. An increase in respiration intensity after BTH treatment was observed. The total phenolic and flavonoid contents and the activity of phenylalanine ammonia-lyase, peroxidase, and polyphenol oxidase were increased in BTH-treated sweet potatoes. This suggests that BTH increases phenylpropanoid metabolism. https://www.selleckchem.com/products/puromycin-aminonucleoside.html CONCLUSION Postharvest 100 mg L-1 BTH treatment could promote wound healing in mechanically damaged sweet potatoes. The activation of the phenylpropanoid metabolism might be the mechanism of action of BTH in wound healing. © 2020 Society of Chemical Industry. © 2020 Society of Chemical Industry.PURPOSE/OBJECTIVES In response to the growing number of violent acts on college/university campuses in the US, a pilot safety awareness and violence prevention (SAVP) training was developed and collaboratively implemented for first-year dental and pharmacy students at a US academic health center. The study assessed student knowledge of violent behavior, warning signs emphasizing active shooter situations, response strategies when witnessing or experiencing violence, and awareness of available violence prevention resources. METHODS In 2014, a presurvey/postsurvey design was approved by the Institutional Review Board and used to assess knowledge before and after SAVP training by the university police department. As part of the new student orientation, 90% of the dental students and 100% of the pharmacy students simultaneously participated in the training and afterwards completed both number-coded surveys. This resulted in a 96% response rate. Data were analyzed using SAS. RESULTS A comparison of presurvey/postsurvey responses show notable increases on 4 key topics awareness of actions to take if witnessing violent crime (+49%) or encountering active shooter situation (+74%), awareness of violent behavior warning signs (+63%), and knowledge of available violence prevention resources (+86%). CONCLUSIONS Findings from this study demonstrate that integrating SAVP training in new student orientation can increase safety awareness among dental and pharmacy students. SAVP training can augment the uptake of current campus resources given there was an observed increase in knowledge of availability. Collaborating with the university police department is key to this replicable proactive SAVP program for dental and pharmacy students. © 2020 American Dental Education Association.Endometrial cancer is the most common genital cancer in high-resource countries. Treatment is essentially surgical, but the role of lymphadenectomy in the treatment of low-stage and low-grade tumors has not been defined. Although no tumor factors have been validated for use as preoperative prognostic markers of endometrial cancer at yet, human epididymis protein 4 (HE4) has received much interest as a potential diagnostic and prognostic tumor marker. Since 2008, several studies have explored its utility in the management of endometrial cancer HE4 may be a useful preoperative prognostic marker because it is associated with lymphatic metastasis and other unfavorable factors in endometrial cancer. In addition, some studies have explored a HE4 cutoff value to classify patients according to lymph node involvement. HE4 might be beneficial as a serum marker that helps clinicians in the decision-making algorithm for treatment of endometrial cancer, enabling them to perform individualized operations and decrease the adverse effects of unnecessary surgery.

We report a crucial role of the signal adaptor proteins CRK and CRKL in promoting EMT and tumor aggressiveness, as well as resistance against chemotherapy in colorectal and pancreatic carcinoma. Genetic loss of either CRKL or CRK partially counteracted EMT in three independent cancer cell lines. Strikingly, complete loss of the CRK family shifted cells strongly toward the epithelial phenotype. Cells exhibited greatly increased E-cadherin and grew as large, densely packed clusters, completely lacked invasiveness and the ability to undergo EMT induced by cytokines or genetic activation of SRC. Furthermore, CRK family-deficiency significantly reduced cell survival, proliferation and chemoresistance, as well as ERK1/2 phosphorylation and c-MYC protein levels. In accordance, MYC-target gene expression was identified as novel hallmark process positively regulated by CRK family proteins. Mechanistically, CRK proteins were identified as pivotal amplifiers of SRC/FAK signaling at focal adhesions, mediated through a novel positive feedback loop depending on RAP1. Expression of the CRK family and the EMT regulator ZEB1 was significantly correlated in samples from colorectal cancer patients, especially in invasive regions. Further, high expression of CRK family genes was significantly associated with reduced survival in locally advanced colorectal cancer, as well as in pan-cancer datasets from the TCGA project. Thus, CRK family adaptor proteins are promising therapeutic targets to counteract EMT, chemoresistance, metastasis formation and minimal residual disease. As proof of concept, CRK family-mediated oncogenic signaling was successfully inhibited by a peptide-based inhibitor. © 2020 The Authors.
