Inflammation and oxidative stress contribute to liver injury. Amla (Emblica officinalis Gaertn.) is rich in vitamin C, gallic acid, flavonoids, and tannins, which may protect against hepatoxicity-induced liver injury. We elucidated the effects of supplementary Amla (100 mg/kg of body weight) on N-nitrosodiethylamine-induced injury by evaluating reactive oxygen species (ROS) responses in the liver and bile, the degree of accumulated leukocytes and Kupffer cell infiltration, 3-nitrotyrosine and 4-hydroxynonenal stains, apoptosis and autophagy, plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), and γ-glutamyl transpeptidase (γ-GT) levels, and antioxidant/oxidant enzymes in rats. Amla was more potent than vitamin C in scavenging O_2^−·, hydrogen peroxide, and nitric oxide. N-Nitrosodiethylamine increased ROS production in liver and bile, hepatic Kupffer cell and leukocyte infiltration, 3-nitrotyrosine and 4-hydroxynonenal accumulations, apoptosis and autophagy, and plasma ALT, AST, and γ-GT levels in the rats, decreased hepatic manganese superoxide dismutase (MnSOD) and catalase protein expressions, and enhanced inducible nitric oxide synthase (iNOS) and cytochrome P450 2E1 (CYP2E1) protein expressions. Amla significantly preserved MnSOD and catalase expressions and decreased iNOS and CYP2E1 protein expressions in N-nitrosodiethylamine-treated livers. Amla decreased N-nitrosodiethylamine-enhanced hepatic apoptosis and autophagy appearances via down-regulation of the Bax/Bcl-2 ratio and Beclin-1 expression. Thus Amla supplementation counteracts N-nitrosodiethylamine-induced liver injury via its antioxidant, anti-inflammation, anti-apoptosis, and anti-autophagy properties.

Customer Knowledge Management--A Case Study of Taiwan's Plastic Industry
Ho, Yung-Ching,Fu, Hsin-Pin,Niu, Chun-Fa,Chien, Pei-Hsiang The Korean Society for Quality Management 2004 The Asian Journal on Quality Vol.5 No.2
This paper investigates customer knowledge management activities of Taiwan's plastic industries. The results demonstrate that the bulk of customer knowledge comes from data related to customer purchase orders and complaints. Furthermore, marketing, production, and research and development are the main departments that developed and reuse customer knowledge. The benefits derived from knowledge management for enterprises do not vary with the position of the vendor on the business scope. In addition, the benefits derived by customers from knowledge management are directly related to the benefits gained by the five major business functions, while the benefits derived from the customer knowledge management are also directly related to customer satisfaction. Summarizing the above results, an Acquisition-Development-Reuse (ADR) model is proposed and can provide the enterprises with a systematic reference model when the business attempts to construct a customer knowledge management system.

Objective To assess whether carbon monoxide (CO) poisoning increases the incidence of dementia.Methods We searched the Cochrane Library, PubMed, and EMBASE from inception to 14 August 2022. Two authors independently selected studies, assessed the quality of included studies, and extracted data. Any disagreement was resolved by discussion with a third author. Only cohort study with an enough follow-up period was included for systematic reviews and meta-analysis.Results Thirty-three full texts were initially searched, but only three studies met our inclusion criteria, and they were comprised of 134,563 participants who were initially free of dementia. The follow-up period ranged from 9 to 12 years. We found that CO poisoning increased the risk of dementia incidence (adjusted hazard ratio 2.61, 95% confidence interval 1.56 to 4.36, p=0.0003). Subgroup analysis showed that the increased dementia risk was significant in males but not in females, and the highest risk was in young age group, followed by in middle age group, but not in the old one.Conclusion Overall the evidence from prospective cohort studies supported a link between CO exposure and an increased dementia risk, although all the included studies were limited to Taiwanese population.
