Objectives: To explore differentiated instruction within a calculus curriculum. For college students to learn concentration, motivation and the impact of academic achievement; explore the attitudes and ideas of students on differentiated instruction within a calculus curriculum; build up the diversity of mathematics education within varied educational settings. Participants: Sample data were collected from freshman students of the Army Academy: total sample = 60, experimental and control group each had 30. Methods: Quasi-experimental design. Study tested whether differentiated instruction would enhance calculus instruction, compared with a traditional teaching method. Results: As hypothesized, results showed a significant difference in calculus achievement between experimental and control groups. Conclusions: Results supported the effectiveness of differentiated instruction on calculus curriculum. Finally, depending on the research results, the researcher provided practical suggestions for the educational research.

Local anesthetics are commonly used in various clinical settings for both prevention and symptom relief. Numerous clinical studies have demonstrated that intra-articular injections of local anesthetics achieve high success rates in orthopedic practices. However, several widely used local anesthetics, including bupivacaine, lidocaine, and ropivacaine, have been shown to exhibit toxicity to chondrocytes, with the underlying mechanisms of chondrotoxicity remaining poorly understood. In this study, we aimed to investigate the cytotoxic effects of local anesthetics, specifically focusing on the consequences of a single intra-articular injection in human chondrocyte cells. Our results reveal that lidocaine, levobupivacaine, bupivacaine, and ropivacaine induced cell death, characterized by the induction of apoptosis and the suppression of cellular proliferation. These effects were mediated through mechanisms involving oxidative stress, mitochondrial dysfunction, and autophagy pathways. We found that the toxic effects of local anesthetics were concentration-dependent, with lidocaine exhibiting the lowest cytotoxicity among the tested agents in TC28a cells. Notably, bupivacaine and levobupivacaine displayed significant cytotoxic effects related to apoptosis, cellular proliferation, reactive oxygen species generation, mitochondrial membrane potential depolarization, and autophagy in human chondrocyte cells. Our findings not only support existing clinical studies but also highlight potential targets for developing protective agents to mitigate serious side effects associated with their use in orthopedic practices.

Tons of broiler livers are produced yearly in Taiwan but always considered waste. Our team has successfully patented and characterized a chicken‐liver hydrolysate (CLH) with several biofunctions. Chronic alcohol consumption causes hepatosteatosis or even hepatitis, cirrhosis, and cancers. This study was to investigate the hepatoprotection of CLH‐based supplement (GBHP01™) against chronic alcohol consumption. Results showed that GBHP01™ could reduce (p <.05) enlarged liver size, lipid accumulation/steatosis scores, and higher serum AST, ALT, γ‐GT, triglyceride, and cholesterol levels induced by an alcoholic liquid diet. GBHP01™ reduced liver inflammation and apoptosis in alcoholic liquid‐diet‐fed mice via decreasing TBARS, interleukin‐6, interleukin‐1β, and tumor necrosis factor‐α levels, increasing reduced GSH/TEAC levels and activities of SOD, CAT and GPx, as well as downregulating CYP2E1, BAX/BCL2, Cleaved CASPASE‐9/Total CASPASE‐9 and Active CASPASE‐3/Pro‐CASPASE‐3 (p <.05). Furthermore, GBHP01™ elevated hepatic alcohol metabolism (ADH and ALDH activities) (p <.05). In conclusion, this study prove the hepatoprotection of GBHP01™ against alcohol consumption.
