Realizing the importance of corporate governance, many governments have embarked upon various initiatives. In Malaysia, the recently introduced Green Book program aims to strengthen the corporate governance among the government-linked companies （GLCs）, in view of their significant contributions to the national socio-economic development. The Green Book initiative, launched in 2005, contains, among other things, a provision to create a high-performing board. Performance of GLCs, therefore, is likely to scale better heights with the modification of the constitution of the boards. The present paper aims to examine the association between the selected corporate governance attributes and performance of GLCs in 2010, approximately five years since the implementation of the transformation program. The regression analysis reveals that none of the selected corporate governance indicators has significantly impacted the performance of GLCs. The findings serve as a wake-up call to the authorities to appraise the effectiveness of the transformation program in enhancing the performance of GLCs.

Recent clinical research has demonstrated that berry fruits can prevent age-related neurodegenerative diseases and improve motor and cognitive functions. The berry fruits are also capable of modulating signaling pathways involved in inflammation, cell survival, neurotransmission and enhancing neuroplasticity. The neuroprotective effects of berry fruits on neurodegenerative diseases are related to phytochemicals such as anthocyanin, caffeic acid, catechin, quercetin, kaempferol and tannin. In this review, we made an attempt to clearly describe the beneficial effects of various types of berries as promising neuroprotective agents.
