Along with thedevelopment of the starchy endosperm, the nuclei of the cells showed chromatin condensation,the typical feature of programmed cell death (PCD). The nuclei also showed nucleusdeformation, disruption of nuclear envelope, nucleoplasm leaking into the cytoplasm andnucleus disintegration resulting in nuclear residue formation. From the nucleus deformationto the nucleus disintegration, the morphological changes of the nucleus were orderlyprogressive. This indicated that the cell death of starchy endosperm in rice wasprogrammed cell death. Evans Blue staining observation showed that the cell death wasinitially detected in the central part of starchy endosperm in rice, then expandedoutward. The activities of superoxide dismutase (SOD) and catalase (CAT) in rice starchyendosperm both descended continuously as development progressed. The analysis of DNA ofrice starchy endosperm did not show the presence of DNA laddering. The above resultsshowed that the cell death of starchy endosperm in rice was a special form of PCD.展开更多

We find that this model shows different scaling behavior depending on the driving mechanism used. With the noisy driving, the rice-pile model violates the finite-size scaling hypothesis, whereas, with fixed driving, it shows well defined avalanche exponents and displays good finite size scaling behavior for the avalanche size and time duration distributions.展开更多
In this paper, by applying a vector-valued inequality we obtained a decomposition theorem on Herz spaces over locally compact Vilenkin groups with new range 0<q≤1.

Methods: this paper mainly selects patients who received knee arthroscopy anterior cruciate ligament reconstruction in our hospital from January to December 2021 as the research subjects, including 112 cases, divided into control group (56 cases) and experimental group (56 cases). The main method used in the two groups was the conventional treatment concept;the experimental group was mainly treated with the concept of fast recovery surgery. After the clinical treatment, the application value and effect of the concept of fast recovery surgery were evaluated from the Judet and Lysholm scores, postoperative recovery index, satisfaction and infection rate. Results: the Judet and Lysholm scores were compared, and the excellent and good rates were compared between the two groups at 3 months and 6 months after surgery. Among them, the postoperative score of the experimental group was significantly higher than that of the control group, and the difference between the two groups was statistically significant (P<0.05). The recovery from various indicators in the control group and the experimental group, such as: the length of hospital stay in the control group was longer than that in the experimental group;the recovery time of the knee joint range of motion in the control group was relatively longer;the VAS and BI scores in the experimental group were better than those in the control group. Comparing the satisfaction of patients between the two groups, the satisfaction of patients in the experimental group was significantly higher than that in the control group, and the two groups were statistically significant (P<0.05). Comparing the infection rates of the two groups, the infection rate of the control group was 14.29%, and the infection rate of the experimental group was 1.79%, which fully demonstrated that there was a statistically significant difference in the infection rates between the two groups (P<0.05). Conclusion: in the process of patients undergoing knee arthroscopy anterior cruciate ligament reconstruction, the use of fast rehabilitation surgery concept is more effective than traditional treatment, which can effectively speed up the patients rehabilitation process, shorten the patients hospitalization time and recovery time, and improve the patients experience. Satisfactions with clinical treatment improve patients limb function and then obtain higher quality of life.展开更多
