Rapid industrialization and urbanization pose pressure on water resources in China. Virtual water trade proves to be an increasingly useful tool in water stress alleviation for water-scarce regions, while bringing opportunities and challenges for less developed water-rich regions. In this study, Yunnan, a typical province in southwest China, was selected as the case study area to explore its potential in socio-economic development in the context of water sustainability. Both input-output analysis and structural decomposition analysis on Yunnan's water footprint for the period of 2002-2012 were performed at not only an aggregated level but also a sectoral level...

California faces significant energy and water infrastructure planning challenges in response to a changing climate. Immediately following the most severe recorded drought, the state experienced one of its wettest water years in recorded history. Despite the recent severe wet weather, much of the state's critical groundwater systems have not recovered from the drought. The recent Sustainable Groundwater Management Act (SGMA) aims to eliminate future depletion risks, but may force California basins to seek alternative water sources by limiting groundwater withdrawals during droughts...

Autoimmune hepatitis (AIH), a serious autoimmune liver disease, can be a lifelong illness, leading to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). So far the mechanisms for disease initiation are largely unknown. Here we report that the amplified non-AIH liver inflammation could promote the initiation of AIH due to the sustained increase of IL-6, IL-12, IL-4, and IL-25 in the liver. The liver injury resulting from virus (adenovirus) or chemicals (CCl4 ) could induce an amplified (stronger/long-lasting) hepatic inflammation by releasing the ligands for TLR2/TLR4...

Andrew Chapman, Yosuke Shigetomi
This study investigates how our lifestyles can cause societal issue including a reduction in social equity due to the consumption of natural resources. Based on a range of household environmental footprints and their application to a quantitative social equity evaluation framework, a methodology is proposed which identifies the creation and origin of public bads within society. This research builds on the methodologies of energy policy sustainability evaluation incorporated with environmentally extended input output analysis in order to critically assess lifestyle-based consumption impacts, and to quantify the allocation of subsequent burdens across generations...

Experimental autoimmune encephalomyelitis (EAE), the most common model for multiple sclerosis, is characterized by inflammatory cell infiltration into the central nervous system and demyelination. Previous studies have demonstrated that administration of some polyphenols may reduce the neurological alterations of EAE. In this work, we show that ellagic acid, a polyphenolic compound, is beneficial in EAE, most likely through stimulation of ceramide biosynthesis within the brain. EAE was induced in Lewis rats by injection of guinea-pig spinal cord tissue along with Freund's complete adjuvant containing Mycobacterium tuberculosis...

Dengue virus (DENV) emerged from the sylvatic environment and colonized urban settings, being sustained in a human-Aedes-human transmission chain, mainly by the bites of females of the anthropophilic species Aedes aegypti. Herein, we sought evidence for fine-tuning in viral codon usage, possibly due to viral adaptation to human transmission. We compared the codon adaptation of DENV serotype 2 (DENV-2) genotypes from urban and sylvatic habitats and tried to correlate the findings with key evolutionary determinants...

Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) can preferentially initiate apoptosis in malignant cells with minimal toxicity to normal cells. Unfortunately, many human cancer cells are refractory to TRAIL-induced apoptosis through many unknown mechanisms. Here, we report that TRAIL resistance can be reversed in human bladder cancer cell lines by treatment with sulforaphane (SFN), a well-known chemopreventive isothiocyanate in various cruciferous vegetables. Combined treatment with SFN and TRAIL (SFN/TRAIL) significantly induced apoptosis concomitant with activation of caspases, loss of mitochondrial membrane potential (MMP), Bid truncation, and induction of death receptor 5...

REVIEW
Pierre Maudens, Olivier Jordan, Eric Allémann
Osteoarthritis (OA) is the most common degenerative disease of the joint. Despite many reports and numerous clinical trials, OA is not entirely understood, and there is no effective treatment available for this disease. To satisfy this unmet medical need, drug delivery systems (DDSs) containing disease-modifying OA drugs (DMOADs) for intra-articular (IA) administration are required to improve the health of OA patients. DDSs should provide controlled and/or sustained drug release, enabling long-term treatment with a reduced number of injections...

ETHNOPHARMACOLOGICAL RELEVANCE: The dried rhizomes of Paris polyphylla var. yunnanensis are widely used in traditional Chinese medicine (TCM) as hemostatic, antitumor, and antimicrobial agents. More than 70 Chinese patent medicines are based on P. polyphylla var. yunnanensis rhizomes. Steroidal saponins are considered as the main active ingredients of these rhizomes. However, wild populations of P. polyphylla var. yunnanensis are greatly threatened due to the illegal wild harvest and over-utilization of the rhizomes...

Neuronal-glial relationships play a critical role in the maintenance of central nervous system architecture and neuronal specification. A deeper understanding of these relationships can elucidate cellular cross-talk capable of sustaining proper development of neural tissues. In the cerebellum, cerebellar granule neuron precursors (CGNPs) proliferate in response to Purkinje neuron-derived Sonic hedgehog (Shh) before ultimately exiting the cell cycle and migrating radially along Bergmann glial fibers. However, the function of Bergmann glia in CGNP proliferation remains not well defined...

Despite a variety of therapies for advanced metastatic colorectal cancer being available, the outcomes in this malignancy remain sub-optimal. Immunotherapy has been slow to impact the management of this patient group. Checkpoint inhibitors, such as nivolumab, have had disappointing results when used broadly. However, for the subset of patients with microsatellite unstable colorectal cancer the use of checkpoint inhibitors such as nivolumab appears to be transformative, and will provide a new therapeutic option for patient with advanced disease...

Releasing greenhouse gases into the atmosphere because of widespread use of fossil fuels by humankind has resulted in raising the earth's temperature during the past few decades. Known as global warming, increasing the earth's temperature may in turn endanger civilization on the earth by starting a cycle of environmental changes including climate change and sea level rise. Therefore, replacing fossil fuels with more sustainable energy resources has been considered as one of the main strategies to tackle the global warming crisis...

Urban agriculture is making an increasing contribution to food security in large cities around the world. The potential contribution of biodiversity to ecological intensification in urban agricultural systems has not been investigated. We present monitoring data collected from rice fields in 34 community farms in mega-urban Shanghai, China, from 2001 to 2015, and show that the presence of a border crop of soybeans and neighboring crops (maize, eggplant and Chinese cabbage), both without weed control, increased invertebrate predator abundance, decreased the abundance of pests and dependence on insecticides, and increased grain yield and economic profits...

Many important contexts requiring teamwork, including health care, space exploration, national defense, and scientific discovery, present important challenges that cannot be addressed by a single team working independently. Instead, the complex goals these contexts present often require effectively coordinated efforts of multiple specialized teams working together as a multiteam system (MTS). For almost 2 decades, researchers have endeavored to understand the novelties and nuances for teamwork and collaboration that ensue when teams operate together as "component teams" in these interdependent systems...

AIM: Inflammation is a process that underlies sight-threatening ocular surface diseases, and gene supplementation with the plasmid that encodes for p-IL10 will allow the sustained de novo synthesis of the cytokine to occur in corneal cells, and provide a long-term anti-inflammatory effect. This work describes the development of solid lipid nanoparticle systems for the delivery of p-IL10 to transfect the cornea. RESULTS: In vitro, vectors showed suitable features as nonviral vectors (size, ζ-potential, DNA binding, protection and release), and they were able to enter and transfect human corneal epithelial cells...

In Zambia, chronic malnutrition still is one of the most common problem among children. To fight against malnutrition, the easiest short-term solution could be to combine specific types of food with affordable local plants. A large variety of natural food resources grow in Zambia, such as Moringa oleifera (MO), whose leaves are known for their health benefits, but are not consumed much by local populations. We analysed Zambian MO powder obtained from dried leaves and found that it contains large amounts of protein, minerals and vitamins, such as iron, calcium and carotenoids...

Prostate tumors make metabolic adaptations to ensure adequate energy and amplify cell cycle regulators such as centrosomes to sustain their proliferative capacity. It is not known whether cancer associated fibroblasts (CAFs) undergo metabolic re-programming. We postulated that CAFs augment lipid storage and amplify centrosomal or non-centrosomal microtubule organizing centers (MTOCs) through a pigment epithelium-derived factor (PEDF)-dependent lipid-MTOC signaling axis. Primary normal human prostate fibroblasts (NFs) and CAFs were evaluated for lipid content, triacylglycerol-regulating proteins, MTOC number and distribution...
