Isabella Karlsson, Lorena Ndreu, Alessandro Quaranta, Gunnar Thorsén
A method we previously developed has been applied to the determination of the glycosylation pattern of specific proteins in biological samples. Six proteins (alpha-1-antitrypsin, transferrin, haptoglobin, C1 inhibitor, alpha-1 acid glycoprotein, and immunoglobulin G) were studied in serum samples from five individuals and cerebrospinal fluid (CSF) samples from three individuals, to investigate the expected normal distribution of glycosylation patterns and to assess whether this methodology can be used to discriminate between samples from different individuals...

Almost 6 million people died in Poland during the Nazi occupation and about 570 thousand during the Soviet occupation. But the end of the war was not the end of the trauma. Historians estimate that at least 30 thousand people were killed during the Stalinist regime in Poland. In 2012 the Institute of National Remembrance started to search for hidden burials of victims of communism. Many exhumations were carried out under the project. One of them took place in Białystok, eastern Poland. According to information gathered by local historians, a detention centre in the heart of city was the place of secret burials of victims of the communist regime...

In forensic entomology practice, species identification is a prerequisite for any further analysis of collected material. Although morphology-based taxonomy may be hindered by a range of factors, these are not obstacles for a molecular identification approach, so-called DNA barcoding. The Fanniidae are a dipteran family that is attracted to and breeds in decomposing animal carrion and dead human bodies. However, morphological identification of fanniids, both at adult and immature stages, is considered to be difficult, particularly for non-experts...

Oxidative stress is considered a central pathophysiological event in cardiovascular disease, including hypertension. Early age reduction in renal mass is associated with hypertension and oxidative stress in later life, which is aggravated by increased salt intake. The aim of the present study was to examine if renal sympathetic denervation can exert blood pressure lowering effects in uninephrectomized (UNX) rats (3-week old) fed with high salt (HS, 4%; w/w) diet for 4 weeks. Moreover, we investigated if renal denervation is associated with changes in NADPH and xanthine oxidase-derived reactive oxygen species...

Long Jiang, Youli Qiu, Yu Li
The ultraviolet spectra and electron transition information of 209 polybrominated diphenyl ethers (PBDEs) in gas were first calculated via time-dependent density functional theory using Gaussian 09 software. The main and second-order interactional effects of substituent characteristics on the photodegradation of PBDEs were then analysed using a full factorial experimental design. Solvent effects were considered to research the effect and promotion mechanism of solvent molecules on the photodegradation of PBDEs compared with that in gas...

The next generation of ionic liquids must be synthetized taking into account structures that guarantee the suitable properties for a defined application as well as ecological data. Thus, searching of the right methodologies to know, quickly and efficiently, the ecological effects of these compounds is a preliminary task. The effects of two imidazolium based ionic liquids with different anions, 1-butyl-3-methylimidazolium tetrafluoroborate, [C4C1Im][BF4], and 1-propyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [C3C1Im][NTf2], on seedling emergence of six tree species and on the microbial behaviour of two soils were determined in this work...

REVIEW
Amy S McKee, Philippa Marrack
Adjuvants have been deliberately added to vaccines since the 1920's when alum was discovered to boost antibody responses, leading to better protection. The first adjuvants were discovered by accident and were used in the safer but less immunogenic subunit vaccines, supposedly by providing an antigen depot to extend antigen presentation. Since that time, much has been discovered about how these adjuvants impact cells at the tissue site to activate innate immune responses, mobilize dendritic cells and drive adaptive immunity...

The asthma treatment and control might be associated with significant burden on family and community' thus exploring other therapeutic plans could be desirable. The aim of this study was to investigate the effect of salt space on clinical findings and peak expiratory flow rate among children with asthma. In this randomized crossover trial, 34 patients aged 6-14 years old with mild to moderate asthma were selected and randomly divided into two groups. The first group went through a period of salt therapy by staying in the salt room for one hour, three times a week for 3 consecutive weeks and then was under observation for three weeks...

A new method is reported for fabrication of polymeric micro- and nanoparticles from an intermediate patterned surface originated by dewetting of a polymeric thin film. Poly (d, l-lactide-co-glycolide) or PLGA, a biocompatible polymer is used to develop a thin film over a clean glass substrate which dewets spontaneously in the micro-/nano-patterned surface of size range 50nm to 3.5µm. Since another water-soluble polymer, poly vinyl alcohol (PVA) is coated on the same glass substrate before PLGA thin film formation, developed micro-/nano-patterns are easily extracted in water in the form of micro- and nanoparticle mixture of size range 50nm to 3...

Numerous physiological and pathological mechanisms can cause elevated or lowered body core temperatures. Deviations from the physiological level of about 37°C can influence temperature based death time estimations. However, it has not been investigated by means of thermodynamics, to which extent hypo- and hyperthermia bias death time estimates. Using numerical simulation, the present study investigates the errors inherent in temperature based death time estimation in case of elevated or lowered body core temperatures before death...

We present, within Kohn-Sham Density Functional Theory calculations, a quantitative method to identify and assess the partitioning of a large quantum mechanical system into fragments. We then show how within this framework simple generalizations of other well-known population analyses can be used to extract, from first principles, reliable electrostatic multipoles for the identified fragments. Our approach reduces arbitrariness in the fragmentation procedure, and enables the possibility to assess, quantitatively, whether the corresponding fragment multipoles can be interpreted as observable quantities associated to a system's moiety...

For the first time, the scattering light of noble nanoparticles was applied for the simultaneous detection of dual cancer biomarkers. Two nanoprobes with dual scattering light colors were used for the simultaneous imaging of alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA) based on the sandwich-type immunoassay. Since AFP can combine anti-AFP-modified gold nanoparticles which have green scattering light under dark-field microscopic imaging (iDFM) technique while CEA can conjugate anti-CEA-immobilized silver nanoparticles which have blue scattering light, the simultaneous determination of AFP and CEA can be achieved by separately counting the number of green and blue light spots in iDFM technique...

REVIEW
Rachael J Oakenfull, Seth J Davis
The circadian clock provides essential timing information to ensure optimal growth to prevailing external environmental conditions. A major time-setting mechanism (zeitgeber) in clock synchronisation is light. Differing light wavelengths, intensities and photoperiodic duration are processed for the clock-setting mechanism. Many studies on light-input pathways to the clock have focused on Arabidopsis thaliana. Photoreceptors are specific chromic proteins that detect light signals and transmit this information to the central circadian oscillator through a number of different signalling mechanisms...

OBJECTIVE: We hypothesized that self-knowledge and goal-perseverance are mutually reinforcing because of the roles of self-knowledge in directing goal pursuit, and of goal pursuit in structuring the self-concept. METHOD: To test this hypothesis, we used a daily diary design with 97 college-aged participants for 40 days to assess whether daily self-concept clarity and grit predict one another's next day levels. Data were analyzed using multilevel cross-lagged panel modeling...
