REVIEW
Vibha Sinha, Kannan Pakshirajan, Rakhi Chaturvedi
In the current industrial scenario, chromium (Cr) as a metal is of great importance, but poses a major threat to the environment. Phytoremediation provides an environmentally sustainable, ecofriendly, cost effective approach for environmental cleanup of Cr. This review presents the current status of phytoremediation research with particular emphasis on cleanup of Cr contaminated soil and water systems. It gives a detailed account of the work done by different authors on the Cr bioavailability, uptake pathway, toxicity and storage in plants following the phytoextraction mechanism...

Vernal ponds, also referred to as vernal pools, provide critical ecosystem services and habitat for a variety of threatened and endangered species. However, they are vulnerable parts of the landscapes that are often poorly understood and understudied. Land use and management practices, as well as climate change are thought to be a contribution to the global amphibian decline. However, more research is needed to understand the extent of these impacts. Here, we present methodology for characterizing a vernal pond's morphology and detail a monitoring station that can be used to collect water quantity and quality data over the duration of a vernal pond's hydroperiod...

BACKGROUND: Dried blood spots (DBS) are a convenient tool to enable diagnostic testing for viral diseases due to transport, handling and logistical advantages over conventional venous blood sampling. A better understanding of the performance of serological testing for hepatitis C (HCV) and hepatitis B virus (HBV) from DBS is important to enable more widespread use of this sampling approach in resource limited settings, and to inform the 2017 World Health Organization (WHO) guidance on testing for HBV/HCV...

BACKGROUND: The detection and quantification of hepatitis B (HBV) DNA and hepatitis C (HCV) RNA in whole blood collected on dried blood spots (DBS) may facilitate access to diagnosis and treatment of HBV and HCV infection in resource-poor settings. We evaluated the diagnostic performance of DBS compared to venous blood samples for detection and quantification of HBV-DNA and HCV-RNA in two systematic reviews and meta-analyses on the diagnostic accuracy of HBV DNA and HCV RNA from DBS compared to venous blood samples...

Liver ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and a key obstacle to expanding the donor pool in orthotopic liver transplantation (OLT). Although graft autophagy is essential for resistance against hepatic IRI, its significance in clinical OLT remains unknown. Despite recent data identifying heme oxygenase-1 (HO-1) as a putative autophagy inducer, its role in OLT and interactions with Sirtuin-1 (SIRT1), a key autophagy regulator, have not been studied. We aimed to examine HO-1 mediated autophagy induction in human OLT and in a murine OLT model with extended (20h) cold storage, as well as to analyze the requirement for SIRT1 in autophagy regulation by HO-1...

In the UK, hospitals with annual platelet use of less than 500 pools, like our institution, usually do not store platelets on-site and these are only ordered from the national blood service (NBS) when a transfusion is required. In 2016, we piloted routine on-site storage of one pool of A RhD negative PLT. Data were collected retrospectively on units of PLTs ordered from NBS, units transfused to patients, wastage, requirements for emergency deliveries from NBS and overall cost. These were compared to corresponding data from the four preceding years (2012-2015)...

The biogeochemistry of iodine in temperate coastal ecosystems is largely mediated by macroalgae, which act as a major biological sink and source of iodine. Their capacity to accumulate, retain and release iodine has been associated with abiotic and biotic stressors, but quantitative information is limited. We evaluated the seasonal iodine retention capacity of eleven macroalgal species belonging to different systematic groups, collected from two sites in Ireland. Iodine accumulation and retention were then further quantified in Fucus vesiculosus and Laminaria digitata in relation to I(-) concentrations in seawater and temperature...

Hydrogen sulfide (H2S) can increase during abiotic storage of wines, and potential latent sources of H2S are still under investigation. We demonstrate that elemental sulfur (S(0)) residues on grapes can not only produce H2S during fermentation, but also form precursors capable of generating additional H2S after three months bottle storage. H2S could be released from S(0)-derived precursors by addition of a reducing agent (TCEP), but not by addition of strong brine, and the size of the TCEP-releasable pool varied among yeast strain...

STUDY QUESTION: Do nuclear proteins in the germinal vesicle (GV) contribute to oocyte competence acquisition during folliculogenesis? SUMMARY ANSWER: Proteomic analysis of GVs identified candidate proteins for oocyte competence acquisition, including a key RNA processing protein - heterogeneous nuclear ribonucleoprotein A2/B1 (hnRNPA2B1). WHAT IS KNOWN ALREADY: The domestic cat GV, which is physiologically similar to the human GV, gains the intrinsic ability to resume meiosis and support early embryo development during the pre-antral-to-antral follicle transition...

The availability of nitrogen (N) is a critical control on the cycling and storage of soil carbon (C). Yet there are conflicting conceptual models to explain how N availability influences decomposition of organic matter by soil microbial communities. Several lines of evidence suggest that N availability limits decomposition: the earliest stages of leaf litter decay are associated with a net import of N from the soil environment, and both observations and models show that high-N organic matter decomposes more rapidly...

Non-structural carbohydrates (NSCs) form a fundamental yet poorly quantified carbon pool in trees. Studies of NSC seasonality in forest trees have seldom measured whole-tree NSC stocks and allocation among organs, and are not representative of all tree functional types. Non-structural carbohydrate research has primarily focussed on broadleaf deciduous and coniferous evergreen trees with distinct growing seasons, while broadleaf evergreen trees remain under-studied despite their different growth phenology. We measured whole-tree NSC allocation and temporal variation in Eucalyptus obliqua L'Hér...

Purpose of review: There is a vast discrepancy between the number of patients waiting for organ transplantation and the available donor organs. Ex vivo machine perfusion (MP) has emerged in an effort to expand the donor pool, by improving organ preservation, providing diagnostic information, and more recently, acting as a platform for organ improvement. This article reviews the current status of MP with a focus on its role in organ preconditioning and therapeutic interventions prior to transplantation...

BACKGROUND: The need for thawed cryoprecipitate is growing. However, according to current guidelines, the shelf-life of pooled thawed cryoprecipitate at room temperature is limited because of possible bacterial contamination and loss of clotting factor activity. Here we assessed microbial growth and retention of clotting activity in cryoprecipitate stored at 4 °C after thawing to see whether its shelf life could be safely extended. MATERIALS AND METHODS: Pooled thawed cryoprecipitate units (n=10) were maintained at room temperature for 6 hours and then placed at 1-6 °C for 18 hours after thawing...

Contents Summary I. II. III. IV. References SUMMARY: Land ecosystems sequester on average about a quarter of anthropogenic CO2 emissions. It has been proposed that nitrogen (N) availability will exert an increasingly limiting effect on plants' ability to store additional carbon (C) under rising CO2 , but these mechanisms are not well understood. Here, we review findings from elevated CO2 experiments using a plant economics framework, highlighting how ecosystem responses to elevated CO2 may depend on the costs and benefits of plant interactions with mycorrhizal fungi and symbiotic N-fixing microbes...

Hermansky-Pudlak syndrome (HPS) - characterized by the distinct clinical phenotypes of both oculocutaneous albinism and mild bleeding diathesis-is caused by mutations in genes that have crucial roles in the assembly of cellular organelles (skin melanosomes, platelet delta [dense] granules, lung lamellar bodies, and cytotoxic T-cell lymphocyte granules). Immunodeficiency, pulmonary fibrosis and granulomatous colitis are associated with some, but not all subtypes of HPS, with varying degrees of clinical severity...

Soil represents the largest terrestrial organic carbon pool. To address global climate change, it is essential to explore the soil organic carbon storage patterns and their controlling factors. We investigated the soil organic carbon density (SOCD) in 48 grassland sites along the Eurasian steppe eastern transect (ESET) region, which covers the Inner Mongolia grassland subregion and Mongolia grasslands subregion. Specifically, we analyzed the SOCD in the top 30 cm soil layer and its relationships with climatic variables, soil texture, grazing intensity and community biomass productivity...

Anthropologists are increasingly required to account for the data on which they base their interpretations and to make it available for public scrutiny and re-analysis. While this may seem straightforward (why not place our data in online repositories?), it is not. Ethnographic 'data' may consist of everything from verbatim transcripts ('hard data') to memories and impressions ('soft data'). Hard data can be archived and re-analysed; soft data cannot. The focus on hard 'objective' data contributes to the delegitimizing of the soft data that are essential for ethnographic understanding, and without which hard data cannot be properly interpreted...

Cation antiporters of the NHX family are widely regarded as determinants of salt tolerance due to their capacity to drive sodium (Na) and sequester it into vacuoles. Recent work shows however that NHX transporters are primarily involved in vacuolar potassium (K) storage. Over-expression of the K/H antiporter AtNHX1 in tomato increases K accumulation into vacuoles and plant sensitivity to K deprivation. Here we show that the appearance of early leaf symptoms of K deficiency was associated with higher concentration of polyamines...

Sulfur assimilation may limit the pool of methionine and cysteine available for incorporation into zeins, the major seed storage proteins in maize. This hypothesis was tested by producing transgenic maize with deregulated sulfate reduction capacity achieved through leaf-specific expression of the Escherichia coli enzyme 3'-phosphoadenosine-5'-phosphosulfate reductase (EcPAPR) that resulted in higher methionine accumulation in seeds. The transgenic kernels have higher expression of the methionine-rich 10-kDa δ-zein and total protein sulfur without reduction of other zeins...
