“…[36] The redox potential for the H 2 VO 4 − /VO 2+ redox couple is −0.34 V at pH = 7. [37] According to the redox potentials of redox couples in the electron transport chain (Table 1), the +5 valent vanadate (H 2 VO 4 − ) tends to be reduced to the +4 valent VO 2+ (vanadyl) by the nicotinamide adenine dinucleotide phosphate/reduced nicotinamide adenine dinucleotide phosphate (NADP + /NADPH), nicotinamide adenine dinucleotide/reduced nicotinamide adenine dinucleotide (NAD + /NADH), flavin adenine dinucleotide/ reduced flavin adenine dinucleotide (FAD 2+ /FADH 2 ), and flavin mononucleotide/reduced flavin mononucleotide (FMN 2+ / FMNH 2 ) redox couples, [38] according to the following equation: [39] Based on the above analysis, by destructive extraction of electrons from the mitochondrial membrane, the bioreduction of vanadate tends to interrupt the electron transport chain and impair mitochondrial function. Mitochondria are the major source of ROS in most mammalian cell types, and they convert 1-2% of systemically consumed oxygen to ROS under normal conditions, accounting for the production of 60-80% of H 2 O 2 in cells.…”

A biomaterials surface enabling the induction of tumor cell death is particularly desirable for implantable biomedical devices that directly contact tumor tissues. However, this specific antitumor feature is rarely found. Consequently, an antitumor‐cell nanocoating comprised of vanadium dioxide (VO 2 ) prepared by customized reactive magnetron sputtering has been proposed, and its antitumor‐growth capability has been demonstrated using human cholangiocarcinoma cells. The results reveal that the VO 2 nanocoating is able to interrupt the mitochondrial electron transport chain and then elevate the intracellular reactive oxygen species levels, leading to the collapse of the mitochondrial membrane potential and the destruction of cell redox homeostasis. Indeed, this chain reaction can effectively trigger oxidative damage in the cholangiocarcinoma cells. Additionally, this study has provided new insights into designing a tumor‐cell‐inhibited biomaterial surface, which is modulated by the mechanism of mitochondria‐targeting tumor cell death.

“…Te Lower Mekong Delta accounts for as high as 80% of the locals' annual animal protein intake, which is worth around 3 billion USD/year for the productive wetland fshery industry [28]. Te fshery industry in Vietnam accounts for 32% of the annual fsh catch in the Mekong River, reaching an annual volume of 840,000 tons [29]. Tus, regardless of the challenge of the landslides, the fshermen were continuously building houses beside the easily afected riverbanks.…”

This article considers and adds empirical nuances to the recent conceptualization of pro-poor water management. Using the concept of pro-poor hydraulic governmentality along the Vietnam-Cambodia border of Thường Phước commune, we argue that water management is linked to local rural livelihoods in a complex and dynamic pro-poor mechanism. While certain policies organize local populations according to cost-effectiveness ignoring local customs, the practicalities of dealing with such constraints are much more ambivalent. This article demonstrates the structural pro-poor complexity among sand excavation, riverbank landslides, water management, local livelihoods, and populace resettlement. The government’s resettlement plans and the perceptions of residents of these plans are intertwined with a wider political, economic, social, and cultural significance in the context of strong institutional power in Vietnam. Limitations and future research agenda are also indicated in the discussion and conclusion section.

“…Earlier studies have discussed the effect of hydrodynamic and hydro‐morphology factors on the fish dynamics in the Lancang River (Yi et al, 2014; Zhang et al, 2019). The upper Lancang River has a high degree of fish diversity and a large number of fish species (Baran et al, 2012; Li et al, 2019; Valbo‐Jorgensen et al, 2009). However, the commissioned dams have altered the habitat, communities and assemblages of fish in the upper Lancang River basin (Zhang et al, 2018).…”

Dam construction and operation can result in serious disturbances to the downstream flow regime and fluvial process, river morphology and the river's ecological condition worldwide. To understand the effects of discharge and sedimentation on fish habitats and ecosystems, an ecohydraulic approach was applied to one of the mega hydropower schemes in the downstream Lancang River (Tibet). The approach comprised a dam operation module with high flow and sediment transport and the application of a dynamic fish habitat model for assessing habitat fragmentation of two targeted fish species: Schizothorax prenanti (S. prenanti) and Schizothorax davidi (S. davidi). The hydrodynamics of the river system and the assessed fish habitat show a significant impact of dam construction and operation on the downstream riverine ecosystem, in which fish habitats were found rapidly deteriorated with the destruction of feeding and reproductive grounds. To improve fish habitat after dam construction, the sediment supplement was applied to the river and shown to be a useful restoration strategy, which recovers the habitat fragmentation of target fish. Our model not only is useful to predict dam operation impacts on the Lancang River's ecological status but also shows great potential in mitigating hydropower‐induced environmental impacts and developing river conservation guidelines worldwide.
