A Cruz-Alcalde, C Sans, S Esplugas
Despite the high toxicity and resistance to conventional water treatments exhibited by methiocarb (MC), there are no reports regarding the degradation of this priority pesticide by means of alternative purification technologies. In this work, the removal of MC by means of ozonation was studied for the first time, employing a multi-reactor methodology and neutral pH conditions. The second-order rate constants of MC reaction with molecular ozone (O3) and formed hydroxyl radicals (OH·) were determined to be 1...

Individuals with newly diagnosed tuberculosis (TB) were screened for diabetes (DM) with fasting plasma glucose (FPG) in Pakistan. A significant decrease in FPG was observed when TB was treated. Of those with newly diagnosed DM, 46% and 62% no longer had hyperglycemia after 3 and 6 months, respectively. Individuals with known DM also showed a significant decrease in fasting plasma levels when treated for TB, but after 3 months none had normoglycemia, and after 6 months 9.2% were normoglycemic. Thus, TB-related DM may abate when the stress terminates, as is the case in gestational DM...

BACKGROUND: The measure of new drug- or vaccine-based approaches for malaria control is based on direct membrane feeding assays (DMFAs) where gametocyte-infected blood samples are offered to mosquitoes through an artificial feeder system. Gametocyte donors are identified by the microscopic detection and quantification of malaria blood stages on blood films prepared using either capillary or venous blood. However, parasites are known to sequester in the microvasculature and this phenomenon may alter accurate detection of parasites in blood films...

BACKGROUND: The trajectory of dyspnea has been reported among patients approaching the end of life. However, patients near death have been dropped from longitudinal studies or excluded altogether because of an inability to self-report; proxy estimates have been reported. It is not known whether dyspnea or respiratory distress remains stable, escalates, or abates as patients reach last days. OBJECTIVE: Determine trajectory of dyspnea (self-reported) and respiratory distress (observed) among patients who were approaching death...

OBJECTIVE: Epidemiological studies have shown that women of reproductive age have much less possibility of developing Parkinson disease (PD) than men. The beneficial effect of estrogen also has been well-described in both culture and animal models of PD. G protein-coupled estrogen receptor (GPER) is a membrane-associated estrogen receptor, and displayed a neuroprotective role in a mouse model of PD. Since GPER is highly expressed in microglia, we speculate that GPER mediates the neuroprotective function of estradiol through suppressing the neuroinflammation of PD...

The increasing climate changes and global warming are leading to colossal agricultural problems such as abatement of food production and quality. As stomatal development is considered to play a key role in crop plant productivity and water-use efficiency, studying stomatal development is useful for understanding the productivity of plant systems for both natural and agricultural systems. Herein, we report the first-in-class synthetic small molecules enhancing the number of stomata in Arabidopsis thaliana that have been discovered by screening of the chemical library and further optimized by the Pd-catalyzed C-H arylation reaction...

The superhydrophobic antibacterial fabrics with intelligent switchable wettability were fabricated by the crosslink reaction among pH-responsive antibacterial copolymer tethered hydroxyl groups, methylol-contained poly(ureaformaldehyde) nanoparticles (PUF NPs) and hexamethylene diisocyanate. It was found that the surface concentration of N+ were heavily influenced by acid solutions, resulting in the rapid wettability conversion from superhydrophobicity/superoleophilicity to superhydrophilicity/underwater superoleophobicity in remarkably short time...

Plasma concentrations of amino acids (AA), in particular branched chain (BCAA), are often found increased in non-alcoholic fatty liver disease (NAFLD). However, if this is due to increased muscular protein catabolism, obesity and/or increased insulin resistance (IR) or impaired tissue metabolism is not known. Thus, we evaluated a) if subjects with NAFLD non-obese (NAFLD-NO), compared to obese (NAFLD-Ob) display altered plasma AA compared to controls (CT); b) if AA concentrations are associated to IR and liver histology...

BACKGROUND: Platelet donors receive 40 mmol or more of IV citrate anion during donation. When plasma ionized calcium ([Ca(2+) ]) falls by ∼20%, half of the donors report symptoms of hypocalcemic toxicity. Citrus juices contain clinically relevant amounts of citrate anion. We asked whether citrus juice can lower [Ca(2+) ] thus potentially contributing to hypocalcemic toxicity. METHOD: Six volunteers were given 20.4 mmol of citrate anion as grapefruit juice or orange juice...

The local interference of cytokine signaling mediated by siRNA-loaded nanoparticles might be a promising new therapeutic approach to dampen inflammation during pulmonary diseases. For the local therapeutic treatment of pulmonary inflammation, we produced multi-shell nanoparticles consisting of a calcium phosphate core, coated with siRNAs directed against pro-inflammatory mediators, encapsulated into poly(lactic-co-glycolic acid), and coated with a final outer layer of polyethylenimine. Nasal instillation of nanoparticles loaded with a mixture of siRNAs directed against different cytokines to mice suffering from TH1 cell-mediated lung inflammation, or of siRNA directed against NS-1 in an influenza infection model led to a significant reduction of target gene expression which was accompanied by distinct amelioration of lung inflammation in both models...

Source apportionment studies of particulate matter are common and have been performed either as source region analyses using air mass back trajectories or by source type using source apportionment techniques. By combining the two approaches, it is possible to estimate the relative importance of emitters in different regions. PM2.5 samples were collected in Gothenburg between September 2008 and September 2009. The mean daily PM2.5 level was 6.1 μg m(-3) (range 0.79-30.91 μg m(-3)). Elemental analyses were done using Energy dispersive X-ray fluorescence (EDXRF) spectroscopy...

Droplet microfluidics can form and process millions of picoliter droplets with speed and ease, allowing the execution of huge numbers of biological reactions for high-throughput studies. However, at the conclusion of most experiments, the emulsions must be broken to recover and analyze their contents. This is usually achieved with demulsifiers, like perfluorooctanol and chloroform, which can interfere with downstream reactions and harm cells. Here, we describe a simple approach to rapidly and efficiently break microfluidic emulsions, which requires no chemicals...

The ocular side-effects of bisphosphonates have the potential to escalate with their widespread use. We report a patient of osteoporosis who was treated with zoledronic acid infusion. He developed ocular pain, redness, watering, photophobia and swelling of both the eyes. He was diagnosed with acute anterior uveitis and conjunctivitis and treated with topical 1% prednisolone acetate and 1% atropine sulphate. The signs of inflammation abated by one week and the steroids were tapered over the next six weeks. There were no further recurrences...

β-Dicyanovinyl substituted porphyrinogen (OxP-MN) was synthesized and utilized as a novel multifunctional sensor for the detection of biologically and environmentally important analytes. OxP-MN (1) acts as a selective and reversible probe for rapid colorimetric detection of picric acid (PA) among other nitroaromatics by switching between two porphyrinoid states. This system displayed a higher β2 value of 1.7 × 10(8) M(-2) and was able to detect PA down to 1.12 ppm (4.99 μM). β-Dicyanovinyl substituted porphyrinogen (OxP-MN) reported here contains a porphyrinogen anion binding site and a dicyanovinyl group as a cyanide-dependent reactive subunit...

Chlorination is essential to the safety of reclaimed water; however, this process leads to concern regarding the formation of disinfection byproducts (DBPs) and toxicity. This study reviewed the formation and control strategies for DBPs and toxicity in reclaimed water during chlorination. Both regulated and emerging DBPs have been frequently detected in reclaimed water during chlorination at a higher level than those in drinking water, indicating they pose a greater risk to humans. Luminescent bacteria and Daphnia magna acute toxicity, anti-estrogenic activity and cytotoxicity generally increased after chlorination because of the formation of DBPs...

Following Europe and North America, East Asia has become a global hotspot of acid deposition, with very high deposition of both sulfur (S) and nitrogen (N) occurring in large areas in southwest and southeast China. Great efforts have been made in reducing national emission of sulfur dioxide (SO2) since 2006 in China. However, the total emission of nitrogen oxides (NOx) continued to increase until 2011. To evaluate the effects of SO2 and NOx emission abatement on acid deposition and acidification of soil and water, we monitored the chemical composition of throughfall, soil water, and streamwater from 2001 to 2013 in a small, forested catchment near Chongqing city in Southwestern China...

Engineering an efficient biomolecular circuit often requires time-consuming iterations of optimization. Cell-free protein expression systems allow rapid testing of biocircuits in vitro, speeding the design-build-test cycle of synthetic biology. In this paper, we combine this with droplet microfluidics to densely scan a transcription-translation biocircuit space. Our system assays millions of parameter combinations per hour, providing a detailed map of function. The ability to comprehensively map biocircuit parameter spaces allows accurate modeling to predict circuit function and identify optimal circuits and conditions...

Dysfunction in neurotransmission mediated by neurotransmitters causes various neurological disorders. Therefore, receptors and reuptake transporters of neurotransmitters have been focused on as a therapeutic target in neurological disorders. These membrane proteins have high affinity for a specific neurotransmitter and are highly expressed on synaptic membranes. In contrast, xenobiotic transporters have relatively lower affinity for neurotransmitters but widely recognize various organic cations and/or anions and are also expressed in brain neurons...
