This paper explores a way of deploying the classical algorithm named genetic algorithm (GA) with the memristor. The memristor is a type of circuit device with both characteristics of storage and computing, which provides the similarity between electronic devices and biological components, such as neurons, and the structure of the memristor-based array is similar to that of chromosomes in genetics. Besides, it provides the similarity to the image gray-value matrix that can be applied to image restoration with GA. Thus, memristor-based GA is proposed and the experiment about image restoration using memristor-based GA is carried out in this paper. And parameters, such as the size of initial population and the number of iterations, are also set different values in the experiment, which demonstrates the feasibility of implementing GA with memristors.1

Heterocyclic amines (HCAs) have potential carcinogenic and mutagenic activity and are generated in cooked protein‐rich foods. Adding proanthocyanidins (PAs) to these foods before frying is an effective way to reduce HCAs. In this study, polymeric PAs (PPA) and ultrasound‐assisted acid‐catalyzed/catechin nucleophilic depolymerized PAs (UAPA, a type of oligomeric PA) were prepared from Chinese quince fruits (CQF). Different levels of PPA and UAPA (0.05%, 0.1%, and 0.15%) were added to chicken meatballs and tofu; then these foods were fried, and the content of HCAs in them after frying was investigated. The results showed that PPA and, particularly, UAPA significantly inhibited the formation of HCAs in fried meatballs and tofu, and this inhibition was dose‐dependent. The inhibition of HCAs by both PPA and UAPA was stronger in the chicken meatballs than in fried tofu. The level of total HCAs was significantly reduced by 57.84% (from 11.93 to 5.03 ng/g) after treatment of meatballs with 0.15% UAPA, with inhibition rates of 78.94%, 50.37%, and 17.81% for norharman, harman, and 2‐amino‐1‐methyl‐6‐phenylimidazo[4,5‐b]pyridine (PhIP), respectively. Of note, there was a negative correlation between water, lipid, protein, creatine, and glucose content and HCA content in the crust, interior, and whole (crust‐plus‐interior) measurements of all fried samples. Interestingly, PPA and UAPA were found more effective in inhibiting HCAs in the exterior crust than in the interior of the fried chicken meatballs. These results provide evidence that further studies on the reduction of the formation of harmful HCAs in fried foods by adding CQF PAs could be valuable to the fried food industry. Practical Application: Chinese quince proanthocyanidins treatments significantly inhibited the generation of heterocyclic amines (HCAs) in chicken meatballs and tofu when deep‐fried. These results suggest that Chinese quince proanthocyanidins can be used as natural food additive for reducing HCAs in fried foods, laying the foundation for using Chinese quince fruit proanthocyanidins for HCA inhibition in the food industry.

Objective: To assess the effects of platelet and fibrinogen on progressive ovarian cancer., Methods: The platelet counts and fibrinogen levels were measured in 180 initially treated ovarian cancer patients within 2 weeks before and 1 week after operation and 6 months after chemotherapy. The results were compared with those of 40 patients with epithelial ovarian neoplasms., Results: The platelet counts and fibrinogen levels were significantly higher in ovarian cancer patients than in patients with epithelial ovarian neoplasms (P < 0.05), significantly higher in late stage than in early stage (P < 0.05), and significantly lower after operation than before operation (P < 0.05). The platelet counts and fibrinogen levels were also significantly lower 6 months after operation in patients who responded well to the therapies than the levels before operation (P < 0.05); however, such difference did not exist between patients who were refractory to the therapies 6 months after treatment and the post-operation levels (P > 0.05)., Conclusions: Platelet and fibrinogen may be closely correlated with progressive ovarian cancer. Monitoring platelet counts and fibrinogen levels are instrumental for the early diagnosis of cancer and metastasis.
