FIRST RECORD OF THE NEMATODA PARASITES FROM THE FAMILY ANISAKIDAE ON THE Euthynnus alletteratus (Rafinesque, 1810) CAUGHT IN THE MARINE WATERS OF LATTAKIA – SYRIA
No full textThe E. alletteratus is one of the most desirable fish for consumption in general, because of its high nutritional value, Moreover, is one of the richest fish in protein. Severe infection with pathogens, especially parasites, can cause various functional disorders and this affects the quality of its meat.
The A. simplex is one of the most clinically important parasites in human health, the disease in humans manifests nonspecifically, however the consumption of raw or semi-raw seafood is crucial information to link the presence of the parasite with the disease.
Therefore, the identification of parasites that parasitize on E. alletteratus is of great importance, as we found (during current research) the parasite Anisakis simplex (Rud, 1809) on the outer surface of the digestive system of one of them.
The present study was considered as the first report of anisakid larvae from E. alletteratus in the Syrian water
First Record of the Rhadinorhynchus trachuri (Acanthocephala, Rhadinorhynchidae) Parasite on the Auxis rochei from the Marine Waters of Lattakia, Syria
No full textThe aim of this research was to deal with identification of the types of endoparasites observed in the fish species A. rochei caught in the marine waters of Lattakia, the site of infection and prevalence of the parasites found during the current study to be protected from the damages of this parasite. They research was carried out in Department of Zoology, Faculty of Sciences, Latakia University between October 2021 and September 2023. during the research, 263 live specimens of A. rochei were collected; they were taken from the commercial fishermen from Ras Al Basit – Lattakia. All specimens were transferred fresh to laboratory of Hydrobiology in Faculty of Science at Latakia University. Eleven fish were infected by parasites. Fish were dissected and then their body cavities and internal organs were examined. Some parasites were observed inside intestines of some fish; these parasites were collected, counted, processed, examined and saved, and classified according to criteria applied in similar studies. Infection prevalence (%) and mean intensity follow the recommendations of (Bush et al., 1997). In the result, 11 out of 263 examined specimens of A. rochei were infected with 27 parasites found in their intestines. The infection prevalence was 4.18% and its density was 2.45 parasite/ fish. Morphological features (body, eggs, and hooks) of Rhadinorhynchus trachuri agreed with study of Amin (2020). Worms collected were mature females with an orange color, body composed of proboscis, neck and trunk. trunk elongated, sub-cylindrical, somewhat swollen anteriorly, a spinose, and covered with transverse striated cuticle. Proboscis is cylindrical, stout, claviform, densely armed with 12 alternating rows of strongly re-curved 23–25 hooks. In conclusion, the result of this study showed the presence of the parasite R. trachuri inside the intestines of the A. rochei fish that inhabiting the marine waters of the Syria coast of Lattakia. This is the first record of infection of A. rochei fish by R. trachuri in Mediterranean Sea generally and Syrian marine waters especially. In our knowledge, this article will contribute to the ichthyhelminthological studies of marine fish in Syria
Calcineurin inhibitor-induced pain syndrome (CIPS) affects the hips in a renal transplant recipient: A case report
No full textCalcineurin inhibitor-induced pain syndrome is a rare but debilitating complication of organ transplantation. This case report describes a man in his forties who developed bilateral hip pain, an atypical presentation of calcineurin inhibitor-induced pain syndrome, after undergoing renal transplantation. Initially, avascular necrosis was suspected as a potential cause of pain. The initial radiographs revealed no abnormalities. However, high trough levels of calcineurins and subsequent magnetic resonance imaging of the hip revealed bilateral symmetric bone marrow edema, which was consistent with calcineurin inhibitor-induced pain syndrome.Adjustments made to the immunosuppressive regimen and multidisciplinary management resulted in an improvement in the patient's symptoms. This case report emphasizes the importance of adopting a comprehensive approach to post-transplantation pain management. Moreover, this report emphasizes the importance of considering the diagnosis of calcineurin inhibitor-induced pain syndrome while investigating and managing post-transplantation patients presenting with hip pain. Clinicians need a high index of suspicion for calcineurin inhibitor-induced pain syndrome, thereby contributing to enhanced post-transplantation care and outcomes while improving the quality of life of transplant recipients experiencing musculoskeletal pain
Proturječja u prikazu revolucije u ranim romanima Josepha Rotha
No full textResearch on the work of the Austrian author Joseph Roth (1894–1939) indicates great differences in political attitudes in different stages of his literary career. While at the beginning Roth is labelled a socialist, an ardent advocate of the proletariat, towards the end of his life he develops completely opposing political views, nostalgically evoking the failed Habsburg Empire as the ideal social order, thus becoming synonymous with the notion of “the Habsburg myth in Austrian literature” (Magris 1966). The article challenges the thesis that the mentioned political attitudes are completely contradictory and mutually irreconcilable by analyzing Roth’s perspective on Austro-Marxism and the representation of the revolution in his first three novels (The Spider’s Web, 1923; Hotel Savoy, 1924; Rebellion, 1924) in order to determine whether the inclination to socialism earlier works can be related to criticism of modernity dominant in the later ones
Modelling W/O/W double emulsions preparation in static mixers: accounting for the shear-thinning behaviour of the dispersed phase
No full textInternational audienceThe dispersion of a shear-thinning non-Newtonian fluid using in-line mixers to prepare double emulsions is investigated experimentally and numerically in this study. A two-step method is adopted for the preparation of double emulsions, comprising in a first step the preparation of a reverse water-in-oil (W/O) emulsion using a high-shear rotor-stator device. This inner emulsion is dispersed in a second step into an outer aqueous phase by continuous parallel pumping of both phases through a set of static mixers. The second preparation step is modelled using a population balance equation (PBE) accounting for droplet breakage inside the mixers. Since the inner emulsion behaves as a shear-thinning fluid, the breakage efficiency depends on the local shear rate. Using classical turbulent breakage kernels is therefore inappropriate, hence there is a need for a kernel accounting for the shear-thinning character of the dispersed phase. To tackle this issue, single-phase CFD simulations of the fluid flow through the mixers are carried out showing a high shear rate magnitude near the walls of the pipe and the mixer crossbars. To avoid CFD-PBE direct coupling, the probability density function (PDF) of the shear rate is extracted from the CFD simulations. This PDF is then used to develop a volume-averaged PBE, where a classical Ostwald-de Waele model is employed to relate the apparent viscosity of the inner emulsion to the shear rate. Different experimental parameters influencing the quality of the dispersion are investigated, including the fraction of the inner emulsion phase, the oil viscosity and the inner and outer aqueous phase viscosities. In the different cases, the model captures the transient evolution of the droplet size distribution of the W/O/W double emulsions at the outlet of the mixers while the computational time remains very low

No full textWe report for the first time the presence of frigate tuna Auxis thazard (Lacepède, 1800) off the Syrian marine waters in the eastern Mediterranean Sea. A specimen of A. thazard was caught in Purse seine nets in the fishery for bullet tuna A. rochei (Risso, 1810) in Ras al-Bassit in March 2022
