A new species of Pomatoschistus (Teleostei: Gobiidae) from Southern Anatolia

Pomatoschistus anatoliae sp. n. is described from estuary of Göksu River on the Mediterranean coast of the Anatolia. It is distinguished from its congeners by the suborbital papilla pattern, meristic, and ecological features. DNA barcoding based on COI sequences revealed that there is a high nucleotide sequence divergence to the nearest neighbour. Kimura’s two parameter distances between P. anatoliae sp. n. and other species of Pomatoschistus and Knipowitchia have found to be at least 5.1%.

Exo‐ and surface proteomes of the probiotic bacterium Lactobacillus acidophilus NCFM

Lactobacillus acidophilus NCFM is a well‐known probiotic bacterium extensively studied for its beneficial health effects. Exoproteome (proteins exported into culture medium) and surface proteome (proteins attached to S‐layer) of this probiotic were identified by using 2DE followed by MALDI TOF MS to find proteins potentially involved in bacteria–host interactions. The exo‐ and surface proteomes included 43 and 39 different proteins from 72 and 49 successfully identified spots, respectively. Twenty‐two proteins were shared between the two proteomes; both contained the major surface layer protein that participates in host interaction as well as several well‐known and putative moonlighting proteins. The exoproteome contained nine classically‐secreted (containing a signal sequence) and ten nonclassically‐secreted proteins, while the surface proteome contained four classically‐secreted and eight nonclassically secreted proteins. Identification of exo‐ and surface proteomes contributes describing potential protein‐mediated probiotic–host interactions.     

Auxin, Gibberellin, Cytokinin and Abscisic Acid Production in Some Bacteria

Summary In this study, auxin (indole-3-acetic acid), gibberellin, cytokinin (zeatin) and abscisic acid production were investigated in the culture medium of the bacteria Proteus mirabilis, P. vulgaris, Klebsiella pneumoniae, Bacillus megaterium, B. cereus, Escherichia coli. To determine the levels of these plant growth regulators, high performance liquid chromatography (HPLC) technique was used. Our findings show that the bacteria used in this study synthesized the plant growth regulators, auxin, gibberellin, cytokinin and abscisic acid.

Synthesis and biological evaluation of aminomethyl and alkoxymethyl derivatives as carbonic anhydrase,acetylcholinesterase and butyrylcholinesterase inhibitors

Compounds containing nitrogen and sulfur atoms can be widely used in various fields such as industry, medicine, biotechnology and chemical technology. Therefore, the reactions of aminomethylation and alkoxymethylation of mercaptobenzothiazole, mercaptobenzoxazole and 2-aminothiazole were developed. Additionally, the alkoxymethyl derivatives of mercaptobenzoxazole and 2-aminothiazole were synthesized by a reaction with hemiformals, which are prepared by the reaction of alcohols and formaldehyde. In this study, the inhibitory effects of these molecules were investigated against acetylcholinesterase (AChE), butyrylcholinesterase (BChE) enzymes and carbonic anhydrase I, and II isoenzymes (hCA I and II). Both hCA isoenzymes were significantly inhibited by the recently synthesized molecules, with K_i values in the range of 58–157?nM for hCA I, and 81–215?nM for hCA II. Additionally, the K_i parameters of these molecules for BChE and AChE were calculated in the ranges 23–88 and 18–78?nM, respectively.

Caligus solea n. sp. (Copepoda: Caligidae) parasitic on the common sole Solea solea (Linnaeus) from the north-eastern Mediterranean off the Turkish coast

A new species of caligid copepod, Caligus solea n. sp., is described from the common sole Solea solea (Linnaeus) caught off the north-eastern Mediterranean coast of Turkey. Both sexes of the parasite were collected from all over the upper body surface of its host. The new species belongs to the macarovi-group of species as established by Boxshall & Gurney (Bull Br Mus (Nat Hist) (Zool), 39:161–178, 1980), with which it shares the following four characters: (i) leg 4 with two-segmented exopod, distal segment carrying three apical spines but no lateral spine; (ii) distal exopodal segment of leg 1 with three plumose setae posteriorly plus four distal margin elements, spine 1 naked, spines 2 and 3 with accessory process and spine 4 about twice length of the others; (iii) females with one-segmented abdomen while males with two-segmented abdomen; (iv) male maxilliped with myxal process opposing the tip of the subchela. However, the new species differs from its congeners within the macarovi-group in the number of sensillae on each papilla on and around the postantennal process, and also in the absence of serrations along the distal margin of the maxilla. This is the twenty-eighth species of Caligus to be reported from the Mediterranean Sea.     

Comparison of novel and familiar commercial kits for detection of C-reactive protein levels

In this study, randomized patient sera were used to simultaneously evaluate an automated C-reactive protein (CRP) assay and a commercial semi-automated microCRP assay with respect to correlation, linearity, and accuracy. Patient specimens were analyzed; two independent assay runs were performed on i-CHROMA (Boditech Med Inc., Korea) and IMMAGE 800 (Beckman Coulter Inc., USA) analyzers to estimate the between- and within-run precision. All systems were calibrated, and quality-control materials were analyzed according to the manufacturer’s instructions. The results using the control materials were within the respective manufacturers’ specified limits. The comparison studies were designed using the CLSI EP9-2A guidelines. The mean serum CRP concentrations were 123.2 ± 123.5 mg/L (95 % confidence of interval (CI) 97.9–148.3) using the CRP assay and 130.1 ± 109.3 mg/L (95 % CI 107.9–152.4) using the microCRP assay. The variance values were σ = 15,252.6 and 11,935.8 for the CRP and microCRP assays, respectively. The concordance correlation coefficient value was calculated as 0.8314 (95 % CI 0.7594–0.8833). There was a significant correlation between the CRP and microCRP assays: r = 0.8392 and 95 % CI 0.7675–0.8902 (p < 0.0001). The CRP and microCRP detection methods were well correlated. The i-CHROMA has many advantages over the IMMAGE 800 with respect to space required, analysis time, and system setup/application costs in a laboratory. It may be an attractive instrument for small and intermediate medical centers.     

Electronic Excited States of the CP29 Antenna Complex of Green Plants: A Model Based on Exciton Calculations

We have suggested a model for the electronic excited states of the minorplant antenna, CP29, by incorporating a considerable part of the currentinformation offered by structure determination, site-directed mutagenesis,and spectroscopy in the modeling.We have assumed that the electronic excited states of the complex havebeen decided by the chlorophyll-chlorophyll (Chl) and Chl-proteininteractions and have modeled the Coulombic interaction between a pairof Chls in the point-dipole approximation and the Chl-protein interactionsare treated as empirical fit parameters.We have suggested the Q_y dipole moment orientations and the siteenergies for all the chlorophylls in the complex through a simultaneoussimulation of the absorption and linear dichroism spectra.The assignments proposed have been discussed to yield a satisfactoryreproduction of all prominent features of the absorption, linear and circulardichroism spectra as well as the key spectral and temporal characteristics ofthe energy transfer processes among the chlorophylls.The orientations and the spectral assignments obtained by relatively simpleexciton calculations have been necessary to provide a good point ofdeparture for more detailed treatments of structure-function relationship inCP29. Moreover, it has been discussed that the CP29 model suggested canguide the studies for a better understanding of the structure-functionrelationship in the major plant antenna, LHCII.
