Introduction of species outside their native distribution ranges, followed by population establishment and becoming an invasive element, has been a common task and a controversial issue in the last century. The topmouth gudgeon Pseudorasbora parva is a gobionid fish native to southeast Asia, with a high dispersion potential, which succeeded in spreading out in many countries of Eurasia and north Africa including Iran during the almost 50 years. In this study, we are addressing the following research questions: (1) how do fish morphology differ in different water bodies by applying traditional, and geometric morphometric methods? (2) does morphology of P. parva show previous molecular-phylogenetic research based on mtDNA? Results revealed that traditional morphometric characters do not demonstrate a high phenotypic variation among 20 populations of P. parva collected from nine basins/river drainages. The cluster analysis of Euclidean distances among groups of P. parva populations (nine basins/river drainages) revealed segregation of three populations (Harirood, Esfahan and Mashkid basins). Based on the genetic background and colonisation history of P. parva using the mitochondrial DNA control region (806 bp) and a cytochrome c oxidase subunit I barcode database (615 bp), presence of three matrilineal haplotypes belonging to two distinct lineages; (1) a widespread lineage with a common haplotype found throughout the country and one exclusive haplotype confined to the Mashkid basin, whose origin can be traced back to a single introduction of a small number of propagules from Japan, and (2) a Chinese lineage represented by a single haplotype found in the Shafarood River of the Caspian Sea basin but also translocated to central Iran. This genetic clustering is somehow in correspondence to the dendrogram derived from the cluster analysis of geometric-morphometrics of P. parva populations and might be due to habitat-induced or genetically induced changes (e.g., fish origin), or it may arise due to the combination of both.

Myocardial infarction (MI) is the necrosis of myocardial tissue caused by a decrease in blood oxygen supply caused by a critical blockage of the coronary arteries by embolus or thrombus. MI with ST-segment elevation (STEMI) is associated with complete occlusive in the coronary artery resulting in the death of myocardial tissue, and is the worst form of ACS. This study aimed to compare the biochemical markers of myocardial infarction patients with and without ST elevation, which is an essential step for the proper management of patients. Based on the result, in STEMI complication patients with diabetes show a highly significant increase in AST, LDH, CK-MB and Troponin compared to NSTEMI patients. While patients without diabetes, show highly increase in AST and troponin compared to NSTEMI patients. In disease groups with (ACS) complication, in the case of STEMI, diabetes patients show a significant increase in all biomarkers except Vitamin D and Mg compared to the patients without diabetes. In the case of NSTEMI, diabetes patients show a significant increase in FBS, HbA1C, CK-MB, Troponin, urea, and creatinine compared to the patients without diabetes. The study showed a significant difference in biomarkers between patients having MI with and without diabetes according to forms of acute coronary syndrome STEMI compared to NSTEMI.

In the study, nitrogen oxides were prepared from an organic source (meat), nitric acid, the resulting steam and the containers of nitrate ions were projected onto four types of soil (Loam, Silt), which were placed inside the photo reactor by various acidic, base and neutron media, after which the mixture was irradiated within the reactor for an hour. Measurements of nitrate and nitrite concentrations generated after every 15 minutes were performed by the Multi-Direct-Photometer. The absorption and maximum wavelength were measured by UV and visible detecting the oxide formed during the time limit set for the water solution sample to be drawn from all types of soil studied. The results showed that nitrite and nitrite concentrations correspond to the absorption at all times, and the soil that absorbs nitrogen oxides the most is Silt. Therefore, various types of measurements and the proportions of the elements and compounds present in the soil before and after irradiation were studied. Emphasis was placed on the study of PH and EC electrical conductivity, where it was concluded that the values of electrical conduction increase as the concentration of nitrates and nitrites increases. As for PH values, it was found that silt, before irradiation are base-medial, and because of their influence on the acidic mean, which is the highest absorption ratio, after irradiation they were converted to a neutral medium or near acid, Loam soil get the opposite from a type of acid, and because they are affected by the post-irradiation to the base metal.

Cystic echinococcosis (CE) has been defined as an illness that results from the larval Echinococcus granulosus stage. Treating cystic echinococcosis is fundamentally dependent upon using Albendazole that may typically result in negative side effects, which is why, more sufficient options of treatment being necessary. The re-purposing of the drugs has been considered as a beneficial method to advance the drug development. In vitro proto-scolicidal effect of the piperine and curcumin have been assessed in E. granulosus and expression of calmodulin (CaM) genes, both of them were linked to the cellular signaling activities. Based on the results, curcumin and piperine’s have dose-dependent proto-scolicidal effects to achieve the optimal efficacy that the isolated piperine 20mg/k and 2g/k curcumin showed significant anthelminthic activity compared to the standard anthelminthic drug enhancing the bioavailability of curcumin. Calmodulin, as a dynamic Ca 2+ sensor, mediates various activities of the cellular signaling from E. granulosus will be possibly involved in a significant biological function.

Most pathogenic bacteria have the acquisition of antibiotic resistance. Therefore, continuous research to find a new antibiotic against pathogens is an urgent task to avoid the rapid spreading of diseases. The direction is to create nanomaterials instead of common antibiotics to inhibition some bacteria high effectively. The purpose of this study was to functionalize the gold nanoparticles (AuNPs) with nisin (N) and applied to a group of pathogenic bacteria to evaluate the effectiveness of them in killing the isolated bacteria, including Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium, Bacillus subtilis, Staphylococcus aureus . The TEM study revealed the grain size of AuNPs ranging 1-14nm, whereas the grain size of AuNPs-N ranging 1-120nm. Also, we were measured the XRD of AuNPs and AuNPs-N to find out their structural properties. In addition to the evaluation of biologically active substances by FTIR system. The results through the biological activity showed that the nisin functionalized gold nanoparticles (AuNPs-N) exhibited perfect inhibitory activity against all the isolated bacteria.

An increased understanding of fisheries target species population dynamics is a key requirement for successful management. Age, growth, and mortality of Indian mackerel, Rastrelliger kanagurta were estimated based on samples collected from commercial purse seine fishery in the Egyptian Red Sea between October 2019 and September 2020. The age estimates were based on two readers to increase the accuracy of results. The age estimates, in the period of study, were observed at a maximum age for both sexes at 4 years old and the most sampled occurrences in the second years (2 years old). The von Bertalanffy growth function was estimated for males at L ∞= 343.83 -0.447 (t+0.474) ; for females at L ∞= 367.37 -0.357 (t+0.767) and combined at L ∞= 353.78 -0.406 (t+0.595) . The mortality rate was determined at 1.35, 1.32 and 1.37 year -1 and exploitation ratio at 0.417, 0.511 and 0.492 year -1 for males, females and combined receptively. The length at first maturity (L 50 ) was estimated at 206.9, 208.26 and 207.48 mm for males, females and combined receptively. The updated estimates of these biological parameters, by this study, indicate that R. kanagurta population is more vulnerable to fisheries exploitation than before.

The present study was aimed to investigate sexual dimorphism in morphometric and meristic characters of three carangid species Carangoides ferdau , Carangoides malabaricus, and Gnathanodon speciosus from the Red Sea, Egypt. The basic statistics of the morphometric indices (relative to SL or HL) of the three carangid species considered sexual dimorphism in C. ferdau , C. malabaricus, and G. speciosus regarding some indices that are size-free and valid as a discriminating tool between males and females of the examined species. The type of size allometry of males and females of the three studied species was estimated according to the bivariate concept. No sexual dimorphism was observed in the meristics characters. Additional features should be investigated to determine sexual dimorphism to facilitate the identification for conservatory purposes and correct management.

This study was conducted to assess the species composition , abundance and metrological data influencing fish species diversity based on catch data from landing site of the Sunye Lake. The finding represented that 25 species belonging to 13 families. Cypriniformes was highest composition in community. Both diversity and evenness were low and only a few species were dominated. Low diversity value (H) and highest dominance index values (1-D) were associated with lower diversity estimates for this community. Major dominant species Oreochromis niloticus was the most widely distributed species with a 100% occurrence occurring in the lake. Highest occurrence was recorded during summer. Seasonal abundance of commonly captured species were O. niloticus, Amblypharyngodon atkinsonii, Puntius sophore, Parambassis ranga and Notopterus notopterus . In this community O. niloticus was recorded in the late monsoon and winter whereas A. atkinsonii and P. sophore were recorded in greater abundance during the early monsoon and summer. Finding results indicated that no significant (P<0.05) difference in diversity pattern among the seasons. According to metrological data, we observed similar seasonal pattern trends during two years study. However, productivity was different and their percentage of contribution also differs from each other seasonally. Percent similarity indicated that winter and summer were most similar season in terms of species richness. Seasonal difference in relative abundance indicated that late monsoon and winter were most dissimilarity.

In this study the sagitta morphology of seven species of Gobiidae including three species of the genera Neogobius and four Ponticola , inhabiting the southern part of the Caspian Sea was described and analysed. The goal was to investigate the usefulness and efficiency of sagitta for species identification. The morphological analysis was based on four shape indices, roundness (4S/πOL 2 ), rectangularity (S/OL×OW), ellipticity (OL-OW/OL+OW), and aspect ratio (OL/OW). The results indicated that otolith morphology and morphometry can be used as diagnostic characters distinguishing the Caspian Sea gobies. While the overall shape of otoliths differentiated the genera, the differences in the shape of the dorsal rim and development of posterior dorsal and anterior ventral lobes were particularly important for inter-specific distinction. The discriminant analysis could separate the specimens of genus Ponticola and Neogobius with 61% and 82% classification successes, respectively, proves that otolith shape indices were a more efficient tool for discrimination of otoliths in Neogobius than Ponticola species. Cluster analysis based on otoliths shape indices showed two main clusters, one cluster contains Neogobius species with higher roundness values, possessed more rounded shaped otoliths and the other includes Ponticola species with spindle and elongated shaped otoliths, except P. bathybius , recognized P. bathybius and Neogobius melanostomus as more similar taxa. These results were consistent with the phylogeny of these species proposed by recent molecular studies and indicated that otolith characteristics are partly genetically encoded and therefore have phylogenetic signals. The current research revealed a high degree of morphological variability of otolith shape in different species and confirmed its usefulness in Gobiidae taxonomy and phylogeny.
{"title":"Characteristics of sagittae morphology in seven goby species from the Caspian Sea","authors":"Parisa Davoodi","doi":"10.22034/IJI.V8I3.538","DOIUrl":"https://doi.org/10.22034/IJI.V8I3.538","url":null,"abstract":"In this study the sagitta morphology of seven species of Gobiidae including three species of the genera Neogobius and four Ponticola , inhabiting the southern part of the Caspian Sea was described and analysed. The goal was to investigate the usefulness and efficiency of sagitta for species identification. The morphological analysis was based on four shape indices, roundness (4S/πOL 2 ), rectangularity (S/OL×OW), ellipticity (OL-OW/OL+OW), and aspect ratio (OL/OW). The results indicated that otolith morphology and morphometry can be used as diagnostic characters distinguishing the Caspian Sea gobies.
