María A Rossin, Pablo N De Francesco, Juan T Timi
Dactylogyridae is overwhelmingly the most abundant and diverse taxon among monogeneans in continental waters of South America. Their small body size requires considerable sampling effort and training for collecting and identifying the worms from the gills, skin, nasal cavities, and other microhabitats. Indeed, diagnostic characteristics as sclerites and male copulatory complex are generally less than 100-μm long and are essential for taxonomic description and identification of species. Here, a combination of simple and routine methods for three-dimensional morphological studies on hard structures is proposed for dactylogirids: SDS treatment for clarification of specimens and enzymatic digestion with proteinase K for freeing sclerotized structures, followed by laser confocal microscopy...

A new anisidine possessing benzothiaozle-based chemosensor (1) has been designed and synthesized. The chemosensor 1 was designed to provide hard base environment for ratiometric detection of comparatively less studied Al(3+) ions. In CH3CN, the fluorescence spectra of chemosensor 1 red shifted from 368 to 430 nm with addition of Al(3+) and Hg(2+) ions; while Cu(2+) ions caused quenching of emission intensity of 1. These differential changes observed with Al(3+) and Cu(2+) ions addition enabled chemosensor 1 to construct "NOR" and "TRANSFER" logic gates...

The palatine aponeurosis is a thin, fibrous lamella comprising the extended tendons of the tensor veli palatini muscles, attached to the posterior border and inferior surface of the palatine bone. In dentistry, the relationship between the "vibrating line" and the border of the hard and soft palate has long been discussed. However, to our knowledge, there has been no discussion of the relationship between the palatine aponeurosis and the vibrating line(s). Twenty sides from ten fresh frozen White cadaveric heads (seven males and three females) whose mean age at death was 79 years) were used in this study...

In this paper, the carbon-doped boron nitride nanoplate (C-BNNP) was prepared by pyrolyzing the precursor under N2 and served as an excellent adsorbent for removal of Rhodamine B (RhB). The structure and composition of C-BNNP were characterized and its adsorption behavior for RhB was investigated. Compared with boron nitride nanoplate (BNNP) which was synthesized under NH3, C-BNNP displayed an enhancement of the adsorption capacity for RhB (833mg/g). The adsorption activity was comprehensibly studied by kinetics, isotherm and thermodynamics...

Semiconducting polymers with specific absorption are useful in various applications, including organic optoelectronics, optical imaging, and nanomedicine. However, the optical absorption of a semiconducting polymer with a determined structure is hardly tunable when compared with that of inorganic semiconductors. In this work, we show that the optical absorption of polymer nanoparticles from one conjugated backbone can be effectively tuned through judicious design of the particle morphology and the persistence length of polymers...

Chinese Pharmacopoeia provides nine pesticide Maximum Residual Limits(MRLs) of traditional Chinese medicines(TCMs), The number of pesticides used in production are far more than those listed in pharmacopoeia. The lack of the standards make it's hard to reflect the real situation of pesticide residues in TCMs correctly. The paper is aimed to analyze the data of pesticide residues in TCMs from 7 089 items in 140 reports, and judging the exceedance rate of pesticides in TCMs using the MRLs of European pharmacopoeia,which is widely accepted in many countries...

BACKGROUND: SPECT Myocardial perfusion imaging (MPI) is associated with a relatively high radiation burden and decreasing image quality in heavy patients. Patient-specific low-activity protocols (PLAPs) are suggested but follow-up data is lacking. Our aim was to compare the use of a standard fixed-activity protocol (FAP) with a PLAP in cadmium zinc telluride (CZT)-SPECT MPI. METHODS: We retrospectively included 1255 consecutive patients who underwent CZT-SPECT stress-optional rest MPI...

In Bosnia and Herzegovina, cardiovascular disease accounts for nearly 50% of deaths. Cardiovascular health of resettled Bosnian-Americans has not been well-characterized. Our study aimed to quantify cardiovascular risk in Bosnian-Americans in St. Louis, the largest non-European center of resettlement. Seven community screenings focused on Bosnian-Americans were held. Cardiovascular risk was calculated to stratify individuals into low (<10%), moderate (10-20%), and high (>20%) risk. Those with self-reported coronary heart disease (CHD) or risk equivalent were considered high-risk...

Allergy cases are increasing worldwide. Currently allergies are treated after their appearance in patients. However, now there is effort to make a preventive vaccine against allergies. The rationale is to target patient populations that are already sensitized to allergens but have yet to develop severe forms of the allergic disease, or who are susceptible to allergy development but have not yet developed them. Subcutaneous injections and the sublingual route have been used as the primary mode of preventive vaccine delivery...

REVIEW
Ha Seong Kim, Thomas G Mason
We review advances that have been made in the rheology of concentrated emulsions and nanoemulsions, which can serve as model soft materials that have highly tunable viscoelastic properties at droplet volume fractions near and above the glass transition and jamming point. As revealed by experiments, simulations, and theoretical models, interfacial and positional structures of droplets can depend on the applied flow history and osmotic pressure that an emulsion has experienced, thereby influencing its key rheological properties such as viscoelastic moduli, yield stress and strain, and flow behavior...

Different weight ratios of alginate/gum arabic (GA) solutions were prepared to serve as the wall material of liquid-core hydrogel beads (LHB) that were formulated to protect the total phenolic compounds (TP) of radish by-product juice from degradation during storage and release in simulated gastrointestinal fluid. The diameter of LHB ranged from 4.63 to 5.66mm with a sphericity lower than 0.05. LHB formulated with 25% GA (AGB0.25) exhibited the highest hardness (26.63N), and those formulated with 50% GA (AGB0...

Characterizing the complex spatial and temporal interactions among cells in a biological system (i.e. bacterial colony, microbiome, tissue, etc.) remains a challenge. Metabolic cooperativity in these systems can arise due to the subtle interplay between microenvironmental conditions and the cells' regulatory machinery, often involving cascades of intra- and extracellular signalling molecules. In the simplest of cases, as demonstrated in a recent study of the model organism Escherichia coli, metabolic cross-feeding can arise in monoclonal colonies of bacteria driven merely by spatial heterogeneity in the availability of growth substrates; namely, acetate, glucose and oxygen...

Characteristics of mosquito larval habitats are important in determining whether they can survive and successfully complete their developmental stages. Therefore, data on the ecological factors affecting mosquito density and abundance especially the physicochemical properties of water of their breeding sites, can possibly be helpful in implementing larval management programs. Mosquito larvae were collected using a standard 350 ml dipper from fixed habitats including: artificial pool, river edge, creek and etc, in 30 villages of 16 counties from May-December 2014...

Pulse-wave elastography (SWE) that is one of the mostly used methods in the recent years holds important place in assessment of liver fibrosis. However there is no exact information on the results of liver elastography in healthy pregnant women in the world literature. The aim of the study was to investigate theSWE parameters of liver elastography in practically healthy pregnant women. The subject of the research was 50 practically healthy pregnant women within 18-45 years old (mean age 27.7±0.7). The pregnant women with genital and extragenital diseases were not included to the research...

A new air stable Fe(III) spin crossover (SCO) complex has been synthesized. The compound undergoes abrupt SCO near room temperature with T1/2 (↓) = 244 K and T1/2 (↑) = 278 K. Structural studies of the complex in the high spin and low spin state show that the strong cooperativity and thus the wide hysteresis is driven by an unprecedented anionic conformational change.

Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. Clinically, this cancer is characterized by the presence of severe primary hyperparathyroidism. Diagnosis is based on histological examination but is not always easy. Surgery is the treatment of choice. We report the case of a 59-year old woman with a personal history of arterial hypertension and of recurrent renal lithiasis, presenting with diffuse bone pain associated with asthenia. Neck examination showed hard basi-cervical swelling with nonpalpable lower edge...
