In periods from July 2014 to June 2015, the Research Institute for Marine Fisheries collected data about yield from catch landing of the trawl fisheries in Kien Giang province. Total yield was calculated by Stamatopoulos Constantine’s method in 2002. The results indicated that the total yield of trawls in Kien Giang province was about 592.5 thousand tons one year. In which, the pair trawl’s yield was 84%, the otter trawl’s yield was 16%. The yield structure was different between pair trawl and otter trawl. Main yield components of pair trawl were trashfish and anchovy groups; and those of otter trawl were trashfish, mixed fish and mixed shrimp.

The biochemical and mineral composition, nutritional and energy value of Leymus chinensis in the steppe zone of Eastern Transbaikalia, growing in different soil and ecological conditions, due to the lack of data on these indicators, has been studied. For the first time, the content in dry matter of Leymus chinensis crude protein, sugars, crude fat, crude fiber, nitrogen-free extractive substances, feed units and metabolic energy and its mineral composition was studied. The dependence of the accumulation of nutrients on soil-ecological conditions, the duration of the growing season and the phase of plant development, the adaptive adaptation of this species to prolonged aridization, which causes its vegetative reproduction due to a decrease in generative reproduction, has been established. The protein ratio as an indicator of feed digestibility is characterized as broad (1 : 9.9–15). The amount of digestible nutrients varied in a very narrow range (592.5–602.2), as well as the energy content (10937.6–11116.6 kJ) and metabolizable energy in the food (9187.6–9337.9 kJ), which is associated with a short vegetation period of L. chinensis development in the sharply continental climate of the steppe zone of Eastern Transbaikalia. A specific feature of the mineral composition of this cereal was the high amount of S, as well as the K: Na ratio (7–38) at the norm of 3–5.

Abstract The Chociwel region is part of the Szczecin Trough and constitutes the northeastern segment of the extended Szczecin-Gorzów Synclinorium. Lower Jurassic reservoirs of high permeability of up to 1145 mD can discharge geothermal waters with a rate exceeding 250 m3/h and temperatures reach over 90°C in the lowermost part of the reservoirs. These conditions provide an opportunity to generate electricity from heat accumulated in geothermal waters using binary ORC (Organic Rankine Cycle) systems. A numerical model of the natural state and exploitation conditions was created for the Chociwel area with the use of TOUGH2 geothermal simulator (i.e., integral finite-difference method). An analysis of geological and hydrogeothermal data indicates that the best conditions are found to the southeast of the town of Chociwel, where the bottom part of the reservoir reaches 3 km below ground. This would require drilling two new wells, namely one production and one injection. Simulated production with a flow rate of 275 m3/h, a temperature of 89°C at the wellhead, 30°C injection temperature and wells being 1.2 km separated from each other leads to a small temperature drop and moderate requirements for pumping power over a 50 years’ time span. The ORC binary system can produce at maximum 592.5 kW gross power with the R227ea found as the most suitable working fluid. Geothermal brine leaving the ORC system with a temperature c. 53°C can be used for other purposes, namely mushroom growing, balneology, swimming pools, soil warming, de-icing, fish farming and for heat pumps.

Abstract Background: Transforming growth factor-beta 1 (TGF- ß1) is a novel cytokine marker and also one of the therapeutic targets in the treatment of diabetic kidney disease. Both sodium glucose co-transporter 2 inhibitor and dipeptidyl-peptides 4 inhibitor reduce TGF- ß 1 level in animal studies, but whether it is effective in human is unknown. Objective: To evaluate the effects of combinations of empagliflozin/linagliptin, comparing with empagliflozin alone, in patients with type 2 diabetes. Material and Methods: Subjects are randomized to a combination of empagliflozin 10 mg and linagliptin 5 mg (n = 23), or empagliflozin 10 mg (n = 22) as add-on to standard treatment for 12 weeks. The primary end point is changed from baseline in serum TGF- ß1 at 12 weeks. Results: Among the 45 subjects who completed the study, mean change in TGF-ß1 was -928.2 + 1,204.2 pg/mL, and +206.6 + 592.5 pg/mL in the empagliflozin/linagliptin group and empagliflozin group, respectively (p <0.001). Mean change in estimated glomerular filtration rate (eGFR) increased in the empagliflozin /linagliptin group 4.4 + 7.59 mL/min/1.73m2, whereas mean eGFR decreased in empagliflozin group -0.06 + 11.16 mL/min/1.73m2 (p =0.133). Mean change in HbA1c was -1.3 + 0.6% and -0.4 + 0.6% in empagliflozin/linagliptin and empagliflozin group, respectively (p<0.001). Baseline level of eGFR significantly correlated with baseline TGF- ß1 but did not predict response to therapy. Conclusion: Initial combination empagliflozin and linagliptin may delay progression of kidney fibrosis as early as 12 weeks of treatment. Our study supports that this combination had synergistic action not only glycemic control but also beneficial in kidney protection. Keyword: transforming growth factor - ß1, diabetic kidney disease, combination empagliflozin and linagliptin

References 109The cardiac cell is a complex biological system where various processes interact to generate electrical excitation (the action potential, AP) and contraction. During AP generation, membrane ion channels interact nonlinearly with dynamically changing ionic concentrations and varying transmembrane voltage, and are subject to regulatory processes. In recent years, a large body of knowledge has accumulated on the molecular structure of cardiac ion channels, their function, and their modification by genetic mutations that are associated with cardiac arrhythmias and sudden death. However, ion channels are typically studied in isolation (in expression systems or isolated membrane patches), away from the physiological environment of the cell where they interact to generate the AP. A major challenge remains the integration of ion-channel properties into the functioning, complex and highly interactive cell system, with the objective to relate molecular-level processes and their modification by disease to whole-cell function and clinical phenotype. In this article we describe how computational biology can be used to achieve such integration. We explain how mathematical (Markov) models of ion-channel kinetics are incorporated into integrated models of cardiac cells to compute the AP. We provide examples of mathematical (computer) simulations of physiological and pathological phenomena, including AP adaptation to changes in heart rate, genetic mutations in SCN5A and HERG genes that are associated with fatal cardiac arrhythmias, and effects of the CaMKII regulatory pathway and β-adrenergic cascade on the cell electrophysiological function.

Freshwater planarian flatworms have always fascinated scientists with their ability to regenerate missing body pieces and to maintain tissue homeostasis. This developmental plasticity is due to a population of pluripotent adult stem cells, also called neoblasts. Using the planarian model organism Schmidtea mediterranea, we aim to understand the mechanisms controlling regeneration and neoblast homeostasis. Stem cell studies from other organisms showed that pluripotency can be controlled by epigenetic mechanisms, such as DNA methylation and histone modifications, by affecting gene expression. In S. mediterranea, the gene encoding a Methyl-CpG Binding Domain (MBD) protein ortholog, Smed-mbd213, was identified. Smed-mbd213 is homologous to the vertebrate MBD2 and MBD3, with the latter being found to affect embryonic stem cell differentiation in mammals. In S. mediterranea Smed-mbd213 is expressed in neoblasts, and its knockdown by RNA interference (RNA i) affected both regeneration and tissue homeostasis. Amputated Smed-mbd213(RNAi} animals formed blastema but failed to correctly regenerate the missing structures such as the brain, photoreceptors and the pharynx, and intact Smedmbd213( RNAi) animals gradually regressed tissue. Using markers for neoblasts and their early and late progeny cells on Smed-mbd213(RNAi) intact and regenerating animals, we found that Smed-mbd213 is not required for stem sell maintenance or the formation of some subpopulations of early progeny cells, which in fact accumulated. Smed-mbd213 is actually required for the formation of late progeny cells, representing the first evidence of a neoblast gene that is required for the differentiation of late but not early progeny cells. In addition, Smed-MBD2/3 is the first invertebrate member of the MBD protein family found to be required for stem cell differentiation similar to the mammalian MBD3. In the search for DNA methylation components in S. mediterranea genome, a DNA methyl transferase candidate gene, Smed-Dnmt2, was found, but knockdown experiments did not show any vital role of this gene in the regeneration process. Also, we did not fmd evidence for cytosine methylation in S. mediterranea genome. This means that neoblast ( pluripotency is not controlled by this epigenetic modification and that Smed-MBD2/3 functions independently of cytosine methylation. Finally, to determine more players in the neoblast differentiation process, we analysed the transcriptome of Smed-mbd213(RNAi) animals and performed an RNAi screen on a group of selected transcripts, We found a novel gene called myst-related that is expected to expresses a chromatin modifying protein. Its knockdown by RNAi gave a similar but more severe phenotype than that of Smed-mbd213, affecting tissue differentiation during regeneration and homeostasis. Whether Smed-mbd213 and myst-related function in the same or different pathways, our study presents new effectors of neoblast differentiation that possibly act by modifying the chromatin architecture. ii

Arenicola marina (lugworms) are intertidal marine polychaete worms. Ecologically lugworms are responsible for increasing the permeability of the sand, sediment oxygenation and speeding up carbon cycling via the breakdown of buried organic matter. The worms themselves contain polyunsaturated fatty acids that are commercially important in the aquaculture of fin and shellfish. There is, however, some debate over the principal carbon source for the worms themselves. The aim was to investigate the bacterial dynamics in a polychaete worm growth mesocosm and determine the potential contribution of polyunsaturated fatty acid biosynthesis by bacteria to the nutrition of Arenicola marina.

This is a study on the diversity of entomopathogenic nematodes (EPN) in Chile and the bionomics of a new EPN species, Steinernema australe. Surveys for EPN were carried out in six regions of Chile, representing some of the principal habitats of the country and including desert, sub-polar, montane and rainforest habitats, by collecting approximately 1400 soil samples. Live-baiting of the samples revealed 101 isolates, 94 of which were Steinernema and seven were Heterorhabditis. Morphological and molecular characterisation revealed one species of Heterorhabditis, designated as Heterorhabditis sp. 1 and three species of Steinernema, viz., S. feltiae and two previously undescribed species, S. australe and S. unicornum. Heterorhabditis sp. 1 was only found in the northern half of the country, the majority of Steinernema were found in the southern half. The most southerly survey, Patagonia and Tierra del Fuego, had the highest proportion of positive soil samples at 18.3%, made up of S. feltiae and S. unicornum; surveys in the Atacama Desert had the lowest return (1-2%), consisting only of Heterorhabditis sp. 1. There were indications of molecular and geographical intraspecific variation in S. feltiae and S. unicornum. The incidence of the four species and a summary of habitat characteristics are provided, as well as taxonomic descriptions of S. australe, S. unicornum and Heterorhabditis sp. 1. Profiling of S. australe revealed a fast life- cycle, with new infective juveniles (IJ) observed after 6 days at 20°C and significant infection at cool, humid conditions. Five days at ea -1°C had no effect on IJ survival, but subsequent infectivity was reduced, a possible chilling-injury. Steinernema australe infected a wide range of insect pests, appearing most effective against Lepidoptera. No nictating or jumping behaviour was observed. Xenorhabdus sp. and Paenibacillus sp. of bacteria were recovered from S. australe.

Two full length AQP genes (LrAQP-A and LrAQP-G) were isolated from the earthworm Lumbricus rubellus by RACE-PCR.  Sequence analysis revealed a number of unusual residues in the critical aqueous pore region in both AQPs, including a substitution in the first canonical NPA box from an alanine residue to a glycine in LrAQP-G. This unusual NPG motif was also identified in AQP genes isolated from a further 6 annelids studied suggesting that although the NPG motif is unique amongst Animalia studied to date, it is common within the annelids.  In addition to this substitution, LrAQP-G contains an insertion of 10 amino acids in its first extracellular loop and putative phosphorylation sites in the intracellular C terminus.  LrAQP-A also contained unusual pore substitutions and putative phosphorylation sites at the C terminus.  Phylogenetic analysis suggests LrAQP-A is more closely related to other invertebrate AQPs whereas LrAQP-G clusters on a branch of its own. Both AQPs were present in all tissues examined, including the major osmoregulatory tissues; integument, nephridia and gut.  qPCR revealed that LrAQP-A transcripts are more abundant than LrAQP-G in the integument, reproductive organs, calciferous glands and nephridia.  In situ hybridisation revealed both transcripts to be largely co-localised in discrete cell types in the outer epidermal cells of the bodywall, the coleomic surface of the gut and in the endothelia of the nephridia. Functional characterisation in oocyte swelling assays revealed that LrAQP-A facilitates the mercury-sensitive transport of water at similar rates to human AQP-5.  The rate of water transport was increased significantly by lowering the pH of bathing media.  LrAQP-G also facilitated water transport but at rates ~50% less than LrAQP-A and was mercury and pH insensitive.  Neither AQP transported glycerol or urea but interestingly LrAQP-A is permeable to NH3 in a pH-dependent manner. Both LrAQP-A and LrAQP-G showed partial loss of function after PKC-mediated phosphorylation. In environmental stress experiments the expression of both genes was modulated significantly.  In worms exposed to wet soil both the integument and nephridia gene expression of LrAQP-A was reduced.  In hyposmotic saline, LrAQP-G was downregulated in the integument.  In hyperosmotic saline LrAQP-G was again downregulated in the integument but was upregulated in the gut. LrAQP-A and LrAQP-G are intimately involved with water transport in L. rubellus.  In addition they seem to be modulated in the short and long term dependent on osmotic conditions.
