Medium-chain fatty acids (MCFA) are important biofuel precursors. Carbon monoxide (CO) is a sustainable electron and carbon donor for fatty acid elongation, since it is metabolized to MCFA precursors, it is toxic to most methanogens, and it is a waste product generated in the gasification of waste biomass. The main objective of this work was to determine if the inhibition of methanogenesis through the continuous addition of CO would lead to increased acetate or MCFA production during fermentation of ethanol...

Several studies suggest an important role of Interleukin-27 in the development of atherosclerosis. The aim of this study was to establish whether the IL-27p28 gene polymorphisms are associated with premature coronary artery disease and/or other cardiovascular risk factors. Four IL-27p28 gene polymorphisms were selected and genotyped in 1162 premature coronary artery disease cases and 1107 controls. rs26528 T and rs40837 A alleles were significantly associated with a lower risk of premature coronary artery disease under different inheritance models (Pdominant = 0...

Carnauba wax is extracted from the leaves of the Copernicia prunífera and contains approximately 80% of esters in its composition. The purpose of the present study was evaluate the hypolipidemic effect of p-methoxycinnamic diesters (PCO-C) extracted from Copernicia prunífera in a model of acute and chronic dyslipidemia in mice. The levels of total cholesterol and triglycerides were significantly reduced plasma levels in PCO-C at the dose of 100mg/kg in a model of acute and chronic dyslipidemia. Histological studies showed that PCO-C has no hepatotoxic effect and reduces hepatic steatosis in animals that consumed hyperlipidemic ration...

Ocean acidification is the increase in seawater pCO 2 due to the uptake of atmospheric anthropogenic CO 2, with the largest changes predicted to occur in the Arctic seas. For some marine organisms, this change in pCO 2, and associated decrease in pH, represents a climate change-related stressor. In this study, we investigated the gene expression patterns of nauplii of the Arctic copepod Calanus glacialis cultured at low pH levels. We have previously shown that organismal-level performance (development, growth, respiration) of C...

The primary objective of any Biopharmaceutical Product Changeover (PCO) program is to employ control strategies before, during, and after the manufacturing process, as well as from the beginning of the lifecycle approach for the equipment and validation, which will minimize the opportunity for cross- contamination when switching between products. Evaluation of the need for an Elastomer Change Out (ECO) should be considered as a segment of an overall changeover assessment. Lifecycle systems (e.g. Preventive Maintenance (PM), Cleanability Coupon Testing, Good Engineering Practices, etc...

Respiratory parameters such as flow or rate have complex effects onto exhalation of volatile substances and can hamper clinical interpretation of breath biomarkers. We investigated effects of progressively applied upper-airway resistances onto exhalation of volatile organic compounds (VOCs) in healthy humans. We performed real-time mass-spectrometric determination of breath volatiles in 50 subjects with parallel non-invasive hemodynamic monitoring, breath-resolved spirometry and capnometry during controlled tidal breathing (12 breaths/min)...

The reactions of the phosphaethynolate anion ([PCO](-) ) with a range of boranes were explored. BPh3 and [PCO](-) form a dimeric anion featuring P-B bonds and is prone to dissociation at room temperature. The more Lewis acidic borane B(C6 F5 )3 yields a less symmetric dimer of [PCO](-) with P-B and P-O bonds. Less sterically demanding HB(C6 F5 )2 and H2 B(C6 F5 ) boranes form a third isomer with [PCO](-) featuring both boranes bound to the same phosphorus atom. Despite the unexpected thermodynamic preference for P-coordination, computational data illustrate that electronic and steric features impact the binding modes of the resulting dianionic dimers...

The stress defence-cascade is mostly not biphasic as Cannon thought, the sympathicotonic stress response is preceded by a vagotonic phase called freeze response. Alteration of the carbon dioxide level plays an important role during defence-cascade as its changes interfere with stress hormones, e.g. with catecholamines, thus affecting the degree of arousal. In case of humans, learned behaviour dominates instead of instinctive, so the fight-or-flight often lags; the consequence can be persistent hypocapnia or hypercapnia...

Previous studies demonstrated that depression is more prevalent in women with polycystic ovary syndrome (PCOS). In this study, we aimed to determine whether amitriptyline (AMT), an antidepressant drug, plays a role in preventing PCOS. The results showed that AMT modified ovarian morphology improved the ovarian functions and estrus cycle in estradiol valerate (EV)-induced polycystic ovary (PCO). AMT restored the levels of estradiol (E2), testosterone (T) and progesterone (P4) to normal, and elevated the level of luteinizing hormone (LH) in EV-induced PCO...

Cases involving polycystic ovaries (PCOs) with adnexal torsion in a natural cycle without ovulation induction are rare, and no reports of such cases have described asynchronous bilateral adnexal torsion. Here, we report a case of PCO syndrome (PCOS) with asynchronous bilateral adnexal torsion in a natural cycle. The patient was a 37-year-old woman with a history of 2 gravidas 1 para. Her primary complaint was left lower abdominal pain. Ultrasonography and MRI identified multiple uterine myomas occupying the pelvis and the left ovary, with oedematous swelling that had moved ventrally to the uterus...

The epithelial-mesenchymal transition (EMT) process plays a pivotal role in the pathogenesis of posterior capsular opacification because of remnant lens epithelial cell proliferation, migration, and transformation after cataract surgery. The latter, we hypothesize, may result in posterior capsule wrinkling and opacification because of a profound change in the lens growth environment via a 1000-fold reduction of extracellular glutathione (GSH) levels. To test this hypothesis, we investigated the EMT process in cell culture and GSH biosynthesis deficiency mouse models...
