Víctor Martín Zelaya, Paula Virginia Fernández, Andrea Susana Vega, Anita Ida Mantese, Ana Ailén Federico, Marina Ciancia
Young shoots of Phyllostachys aurea showed glucuronoarabinoxylans (GAX) as the major hemicellulosic components, being extracted in major amounts with 1M KOH (ratio Xyl:Ara:GlcA, 100:67:8), but also with water, showing a broad structural variability. Mixed linkage glucans were also present, but in minor amounts, mostly concentrated in the 4M KOH extracts, while pectin polymers were very scarce. Arabinogalactan proteins were an important part of water extracts, determined by the presence of the typical arabinogalactan structures (3- and 6-linked Gal p; terminal and 5-linked Ara f), in addition to small amounts of hydroxyproline (2-3% of total protein) and positive reaction to Yariv's reagent...

The Qinling subspecies of giant panda (Ailuropoda melanoleuca qinlingensis), is highly endangered; fewer than 350 individuals still inhabit Qinling Mountains. Previous research revealed captive pandas were exposed to bromine, so we hypothesized that captive pandas were exposed to and affected by polybrominated diphenyl ethers (PBDEs). To test this hypothesis, we tested blood and feces of captive and wild pandas, their drinking water, food (bamboo leaves) from SWARC (Shaanxi Wild Animal Research Center)and FNNR (Foping National Nature Reserve) and supplemental feedstuff given to captive panda at SWARC...

5-Hydroxymethylfurfural (HMF) has been identified as a promising biomass-derived platform chemical. In this study, one pot production of HMF was studied in ionic liquid (IL) under probe sonication technique. Compared with the conventional heating technique, the use of probe ultrasonic irradiation reduced the reaction time from hours to minutes. Glucose, cellulose and local bamboo, treated with ultrasonic, produced HMF in the yields of 43%, 31% and 13% respectively, within less than 10min. The influence of various parameters such as acoustic power, reaction time, catalysts and glucose loading were studied...

Dwarf bamboo-dominated forests are often subjected to temporary periods of drought due to rising air temperature and decreasing rainfall. Nevertheless, the relationship among CO2 assimilation, photoprotective pathways and metabolism of reactive oxygen species (ROS) remains unexplored in bamboo species. Changes in leaf gas exchange, chlorophyll fluorescence, energy partitioning, antioxidative system and compounds related to ROS metabolism in Fargesia rufa plants subjected to drought and subsequent rewatering were analyzed...

Seasickness and its triggers, symptoms, and preventive measures were well known in antiquity. This chapter is based on an analysis of descriptions of motion sickness, in particular seasickness, in ancient Greek, Roman, and Chinese literature. A systematic search was made from the Greek period beginning with Homer in 800 BC to the late Roman period and ending with Aetios Amidenos in 600 AD, as well as in the Chinese medical classics dating from around 300 AD. Major aspects are the following: body movements caused by waves were identified in all cultures as the critical stimuli...

29 Moso bamboo VQ proteins were genome-wide identified for the first time, and bioinformatics analysis was performed to investigate phylogenetic relationships and evolutionary divergence. The qRT-PCR data show that PeVQ genes response to different stress treatments. Accumulating evidence suggests that VQ motif-containing proteins in rice (Oryza sativa), Arabidopsis (Arabidopsis thaliana), and maize (Zea mays) play fundamental roles in response to various biotic and abiotic stresses. However, little is known about the functions of VQ family proteins in Moso bamboo (Phyllostachys edulis)...

In this work, unconventional carbon-based materials were investigated for use in electrochemiluminescence (ECL) working electrodes. Precursors such as bamboo, pistachio shells, kevlar(®) fibers and camphor were differently treated and used as working electrodes in ECL experiments. After a proper process they were assembled as electrodes and tested in an electrochemical cell. Comparison among them and with a commercial glassy carbon electrode (GCE) shows a very good response for all of them thus demonstrating their potential use as disposable low-cost electrodes for early detection electrochemical analysis...

Aiming for the complete utilization of bamboo biomass, an integrated process which combines ethanol production with the recovery of silica and lignin was proposed. To reduce chemical charge required for the fractionation of silica and lignin from bamboo and improve the digestibility of the obtained substrate, a sequentially two-stage pretreatment process of autohydrolysis and alkaline extraction was carried out. From the view of enhancing enzymatic hydrolysis and recovery of silica and lignin, a two-stage treatment of autohydrolysis at 180°C for 90min followed by alkaline extraction at 100°C with 6% NaOH (based on pretreated chips) for 120min was optimized...

The objective of this study was to determine whether common bacterial catfish pathogens could attach and colonize surfaces commonly found in aquaculture facilities. In addition, we evaluated the role of calcium in biofilm formation. Attachment to polystyrene plates was used to quantify biofilm formation by five bacterial pathogens (i.e., Flavobacterium columnare, Aeromonas hydrophila, Edwardsiella ictaluri, E. tarda, and E. piscicida). Flavobacterium columnare and A. hydrophila formed thick biofilms that were enhanced by calcium supplementation...

BACKGROUND: Radiographic severity of ankylosing spondylitis (AS) shows such great variance that some patients never develop syndesmophytes throughout the entire disease span, whereas some develop bamboo spine relatively early. OBJECTIVE: To study the association between ERAP1, IL23R and PTGER4 single nucleotide polymorphisms (SNPs) and radiographic severity in AS patients. METHODS: rs27044 and rs30187 (ERAP1), rs11209032 (IL23R) and rs10440635 (PTGER4) SNPs were genotyped in 235 AS patients fulfilling the modified New York criteria...

Most endangered plant species in a fragmented forest behave as a unique source population, with a high dependence on frugivorous birds for recruitment and persistence. In this study, we combined field data of dispersal behavior of birds and GIS information of patch attributes to estimate how frugivorous birds could affect the effective dispersal pattern of Chinese yew (Taxus chinensis) in a fragmented and disturbed forest. Nine bird species were observed to visit T. chinensis trees, with Urocissa erythrorhyncha, Zoothera dauma and Picus canus being the most common dispersers...

Systemic diseases can affect the larynx. The most common laryngeal involvements, although often unknown, consist in inflammatory laryngitis, laryngeal ulcers, cricoarytenoid arthritis, recurrent laryngeal nerve paresis and subglottic stenosis. The clinical case we report is more uncommon, but representative of autoimmune diseases : vocal folds bamboo nodes in a young female patient, age 34, suffering from active rheumatoid arthritis. In the present article, we detail the current knowledge of this pathology and later discuss different laryngeal involvements of systemic diseases by lesion type et their management...

Low water solubility, extensive metabolism, and drug resistance are the existing unavoidable disadvantages of the insoluble drug curcumin in biomedical applications. Herein, we employed d-α-tocopherol polyethylene glycol 1000 succinate (TPGS)-functionalized near-infrared (NIR)-triggered photothermal mesoporous nanocarriers with bamboo charcoal nanoparticles (TPGS-BCNPs) to load and deliver curcumin for improving its bioavailability. This system could considerably increase the accumulation of curcumin in cancer cells for enhanced curcumin bioavailability via simultaneously promoting the cellular internalization of the as-synthesized composite (TPGS-BCNPs@curcumin) by the size effect of NPs and considerably triggering controlled curcumin release from TPGS-BCNPs@curcumin by NIR stimulation and reducing efflux of curcumin by the P-glycoprotein (P-gp) inhibition of TPGS, so as to enhance the therapeutic effect of curcumin and realize a better chemo-photothermal synergetic therapy in vitro and in vivo...

BACKGROUND: Myanmar has the heaviest burden of malaria in the Greater Mekong Sub-region. Asymptomatic Plasmodium spp. infections are common in this region and may represent an important reservoir of transmission that must be targeted for malaria elimination. METHODS: A mass blood survey was conducted among 485 individuals from six villages in Kayah State, an area of endemic but low transmission malaria in eastern Myanmar. Malaria infection was screened by rapid diagnostic test (RDT), light microscopy and real-time polymerase chain reaction (PCR), and its association with demographic factors was explored...

Developing high-performance non-precious metal cata¬lysts (NPMCs) for the oxygen reduction reaction (ORR) is of critical importance for sustainable energy conversion. We report a novel NPMC consisting of iron carbide (Fe3C) nanoparticles encapsulated in N-doped bamboo-like carbon nanotubes (b-NCNTs), synthesized by a new metal-organic framework (MOF)-templated assembly approach. The electrocatalyst exhibits excellent ORR activity in 0.1 M KOH (0.89 V at -1 mA cm-2) and in 0.5 M H2SO4 (0.73 V at -1 mA cm-2) with a hydrogen peroxide yield of below 1% in both electrolytes...
