Ovarian remnant syndrome in a cat with ovarian tissue in the omentum
Authors: Fontes Gabrielle S. , McCarthy Robert J. 
Published: August 2020

Abstract

CASE DESCRIPTION
A 2-year-old spayed female domestic shorthair cat was evaluated for recurring estrous behavior after ovariohysterectomy and 2 subsequent exploratory laparotomies.

CLINICAL FINDINGS
Physical examination revealed no abnormalities. A serum sample tested positive for anti-Müllerian hormone and had a progesterone concentration consistent with the presence of an ovarian remnant. Results of abdominal ultrasonographic examination suggested presence of a slightly hyperechoic mass caudal to the left kidney.

TREATMENT AND OUTCOME
Exploratory laparotomy was performed when the cat was showing estrous behavior. Tissues at the right and left ovarian pedicles and the uterine stump appeared grossly normal but were excised and submitted for histologic examination. Two small nodules associated with the omentum were removed, and histologic examination results for one of these nodules indicated ovarian tissue with secondary and graafian follicles. Clinical signs of estrus resolved after surgery, and hormonal assay results were within ranges expected for an ovariectomized cat.

CLINICAL RELEVANCE
To the authors’ knowledge, the present case represented the first clinical report of ovarian remnant syndrome in a cat or dog in which persistent ovarian tissue was not found at the site of an ovarian pedicle. Our findings emphasized the importance of exploring the entire abdominal cavity when evaluating a patient for possible ovarian remnant tissue and confirming the excision of ovarian remnant tissue by histologic assessment.

Abstract
The objective of this study was to determine the relationships between intramuscular fat, cholesterol contents and fatty acid composition in the muscles of different animal species. Intramuscular fat, cholesterol and fatty acid composition in 207 muscle samples from 129 animals of different species (pigs, beef cattle, farmed red deer, horses and geese) were determined and analysed. The obtained results indicated unequal relations between intramuscular fat and cholesterol contents and fatty acid proportions in the muscles of different animal species. The increase of intramuscular fat content resulted in higher monounsaturated and lower polyunsaturated fatty acid contents in most muscles of meat producing animals. In all the species higher fatness did not show any increase in cholesterol content and also cholesterol contents were lower as fat increased in m. semimembranosus of pigs and m. pectoralis profundus of horses. The cholesterol content positively correlated with saturated and monounsaturated fatty acids in the longissimus muscle with the lowest fat content found in red deer and beef cattle, whereas the correlations between these measures were negative in m. pectoralis profundus of horses and the breast of goose containing high fat levels. Negative correlations between polyunsaturated fatty acids and cholesterol content were found in the longissimus muscle of red deer and cattle, whereas these correlations in goose breast and horse meat were positive.
Experimental Validation of Equivalent Circuit Modelling of the Piezo-Stripe Harvester Attached to the SFSF Rectangular Plate
Authors: Koszewnik Andrzej 
Published: August 2020

Abstract
Plate-like structures with attached piezo-patch elements are widely used in marine, aerospace and civil infrastructure applications to power small devices with low power demand or used for monitoring of vibration structures. In order to assess the feasibility of an energy harvesting system to generate power output from a harvester, an accurate electromechanical model of the piezo-patch harvester attached to a 2D structure in modal coordinates is required. Taking into account this fact, this study is focused on the analysis of the piezoharvester orientations on the SFSF (Simply Supported-Free-Simply Supported-Free) plate undergoing forced dynamic excitation. The results obtained from the numerical analysis of a smart structure led to determining quasi-optimal piezo-harvester location on the structure, and next, to determining a multi-mode representation of the equivalent circuit model. The experimental set-up carried out on the lab stand properly verified the parameters of the ECM model. Finally, the proposed approach can be used for the structural health monitoring of vibration of some 2D mechanical structures like the front wall of a dishwasher.

Authors: Sulym Heorgij , Opanasovych Viktor , Slobodian Mykola , Bilash Oksana 
Published: August 2020

Abstract
In the article, the pure bending problem for strip (beam) with straight, perpendicular to its axis crack located in the zone of tensile stresses is investigated on the assumption of narrow plastic strips near crack tips. Using methods of the theory of functions of a complex variable and complex potentials, the problem is reduced to the several linear conjunction problems. The solutions of latter problems are obtained in the class of functions confined in the edges of plastic strips. Formulas for the calculation of their lengths are derived. Expressions for the determination of crack tip opening values are written. Numerical analysis of the problem is performed.
An Exploratory Study on the Accuracy of Parts Printed in FDM Processes from Novel Materials

Published: August 2020

Abstract
The paper describes the experiment of assessing the chosen geometric characteristics of test models with simple geometry, shaped by the FDM (fused deposition modelling) method of different materials. The influence of the material grade and the degree of infill density on the shrinkage affecting their dimensional deviations and selected surface topography parameters of printed parts was examined and compared. Three different types of materials were used to fabricate the test models, namely HDGLASS and NANOCARBON, two new fibre reinforced composites available in the market and, additionally ABS, a popular monoplastic material. An infill density ratio of 10, 50 and 90% was assumed for each material. Three specimens were made on the same printer for each infill density, which allowed to assess the repeatability of the analysed characteristics. From among many possible shapes of models, a cube was chosen as representing the simplest geometry, facilitating the measurements themselves and the interpretation of the results. New fibre-reinforced materials are more attractive in industrial applications than pure plastics (ABS) due to their mechanical properties or appearance. They are characterized by a relatively low melting point and short cooling time, after which they can return to their original geometry; however, there is a lack of detailed data on the geometric accuracy of parts made of used composite materials. The presented work was to explanatorily broaden the knowledge about the properties of composite made parts. The practical purpose of the research was that on the basis of measurements, it would be possible to indicate among the materials used that particular material whose properties and method of application would allow obtaining the best quality surface and would be the most resistant to thermal loads. An attempt was also made to explain the possible causes of the differences in the observed characteristics of the tested materials.

Published: August 2020

Abstract
In this paper, the experimental investigations, constitutive description and numerical modelling of low-cycle fatigue behaviour of P91 steel in non-isothermal conditions are presented. First, experimental tests are performed to recognise different aspects of material behaviour. Then, an appropriate constitutive model is developed within the framework of thermodynamics of irreversible processes with internal state variables. The model describes two phases of cyclic softening, related to plastic mechanisms. An important goal of the presented research is to include thermomechanical coupling in the constitutive modelling. Next, the model parameters are identified based on the available experimental data. Some parametric studies are presented. Finally, numerical simulations are performed, which indicate the significant influence of thermomechanical coupling on the response of the constitutive model in thermomechanical fatigue conditions.

Published: August 2020

Abstract
The aim of this study is to develop the numerical–analytical model of frictional heating in a pad/disc system during braking including the pressure fluctuations, engendered by the pump in an anti-skid braking operation. For this purpose, the problem of motion and the one-dimensional thermal problem of friction for a semi-space/semi-space tribosystem were formulated and solved. Obtained solutions allow to calculate temperature distribution on the contact surface and inside the friction elements. Thermal analysis was performed for a metal–ceramic pad and a cast iron disc during one-time braking including the time-dependent, oscillating pressure. The influence of amplitude of pressure fluctuations on the temperature variations was investigated, especially on the value of maximum temperature achieved during braking.

Migraine as the First Symptom for Setting a Clinical Diagnosis
Authors: Neagoe Mariana-Alis 
Published: August 2020

Abstract
The migraine is among the most frequent complains of the patients requesting a medical consultation. I am presenting hereby the case of a 34-year old patient, who complained of diffuse migraine followed several weeks later by vomiting and seizures. The brain computed tomography (CT) and magnetic resonance imaging (MRI) examinations indicate an intracranial spread located in the left (temporal) hemisphere, which had a mass effect on the ventricular system. When performing the extemporaneous examination, it was found an anaplastic oligodendroglioma. Subtotal resection under microscopic guidance was performed, as well as radiotherapy and chemotherapy after the surgery. When discharged from hospital, the patient was surgically cured and had an improved neurological state. The repeated checkups (clinical and paraclinical) indicated no signs of local relapse. Approximately 8 years after the first surgery, the patient returned for a check-up, in view of investigations and treatment, while complaining of migraine and a nervousness state that was bothering his family. The brain MRI indicated a large tumour relapse located in the left temporal-hippocampal region. The histopathology examination indicated that it was an anaplastic oligodendroglioma relapse. Surgery was performed and the tumour relapse located in the left temporal-hippocampal region was completely ablated. After the surgery, the patient was conscious and had no movement dysfunctions.
Neurosteroids in Cognitive Disorder - From Well-Known Pharmacological Aspects to a Source of Controversy
Authors: Bătrînu Mădălina-Georgiana , Tero-Vescan Amelia 
Published: August 2020

Abstract
The nervous system is not just a target organ for synthetic steroids. It is also controlled in a certain manner by steroids synthesized de novo in the brain, at the level of both neurones and glial cells. The impressive recent number of literature studies, clearly demonstrates the presence of enzymes necessary for syntheses of central neurosteroids and also the mechanism by which they act. Neurosteroids play a considerable part as an endogenous modulator of brain function and behaviour processes, and the decrease of their concentration can be associated with the pathophysiology of different neurological diseases accompanied by cognitive disorders such as depression, anxiety, schizophrenia, Alzheimer disease.

Published: August 2020

Abstract
Charcot foot or Charcot neuropathy is a rare disease found in patients with diabetes mellitus and is characterized by bone damage to the foot leading to deformities, instability, functional impotence and even amputation. The mechanism is still under discussion, without a consensus regarding the pathophysiology of this condition. The treatment is a complex one, non-surgical and surgical, the non-surgical one addressing especially the acute phase of the disease, the surgical one being complex and ranging from osteotomy, debridement, arthrodesis, internal or external fixation or even amputation. A good management of diabetes, of its peripheral complications, an early recognition of the Charcot type foot, prevents the evolution towards this serious condition.

Published: August 2020

Abstract
Primary melanoma of the eyelid is a rare malignant tumour that accounts for <1% of all malignant melanomas and about 1% of malignant tumours of the eyelid. The most common clinical presentation of melanoma is an oval lesion; linear presentation is uncommon. We presented a 79-year-old woman with a several-month history of a rapidly-growing, irregular, linear, pigmented cutaneous lesion on the right lower eyelid, involving the eyelid margin. The lesion measured 2 cm x 0,8 cm x 0,2 cm. Anterior and posterior segments appeared normal in both eyes, without pathological findings on ocular ultrasound examination. After excision biopsy, histopathological examination revealed a nodular melanoma. The case underwent additional investigations for staging and therapy. The current therapeutic strategies in eyelid melanoma include surgical excision, systemic chemotherapy, immunotherapy, targeted therapy or radiotherapy. Despite advanced research methods in the field, the management of eyelid melanoma is still a major challenge.

Abstract
A good outcome of an occlusal appliance requires a well-adapted device, both in terms of occlusal relations and internal fit, which helps achieve patient comfort and compliance. Digital technology had led to the manufacturing of night guards that display a better accuracy and properties of the resin, ease of fabrication in terms of time and materials and the possibility of duplication. This technical report describes the clinical and laboratory steps that need to be followed to produce an occlusal appliance in a fully digital protocol. Intraoral scans were acquired, as well as digital occlusal records. A virtual 3D dental device was designed using a CAD software, which was later manufactured via 3D printing technology. The occlusal appliance displayed a good internal fit and enhanced properties of the resin. Minimal occlusal adjustments were required to secure functional guidance during protrusive and lateral movements of the mandible.

Abstract
Persian sturgeon, Acipenser persicus Borodin, has been the most significant proportion of Iranian commercial sturgeon catches in the Caspian Sea over in the last three decades. This endemic species has suffered continuous population declines from the impact of anthropogenic factors. The present study filled in information gaps on underlying population biology parameters, evaluated the population status, and determined the vulnerability risk of the stock extinction of Persian sturgeon in the south Caspian basin of Iran.

= -3.4 years. Sexual maturity of 50% for males and females was FL = 127.2 cm and 137.5 cm, respectively. The long-term age composition data showed 35 age groups, and the ages of 14–18 years comprised 80% of the total catch. Natural mortality was 0.123 years−1, and fishing mortality ranged between 0.104 and 0.331 years −1. The total biomass trend decreased and collapsed from 6,071.3 tons in 1990–91 to 144.1 tons in 2014–15. Although >93% of the catch included maturing specimens, the Persian sturgeon stock is now critically endangered because of several anthropogenic factors.

Published: August 2020

Abstract
The occurrence of runt sturgeon in stocks reared in recirculating aquatic systems is highly undesirable for both production and fish welfare. The aim of this study was to describe the anatomopathological and histopathological changes accompanying the phenomenon of runt sturgeon reared in fully controlled recirculating aquatic conditions. These individuals were characterized by emaciation and cachexia. Histopathological analysis indicated severe chronic non-purulent inflammation of the gastrointestinal tract and exfoliation of enterocytes into the lumen, accompanied by chronic, non-purulent pancreatitis. All pathological findings were probably the result of malnutrition, which further escalated into the disorders observed.

Published: August 2020

AbstractThe goal of the current study was to characterize developmental-induced changes of the metabolic and antioxidant responses in the skeletal muscles of the anadromous sea trout (Salmo truttaL.) from the Baltic Sea and its catchment area rivers. Activities of the metabolic enzymes, i.e., lactate dehydrogenase, succinate dehydrogenase, alanine and aspartate aminotransferases, their ratios representing aerobic, anaerobic, and amino acid metabolisms, the level of the metabolites (pyruvate and lactate), the activities of several key antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase, and reductase), and a marker of lipid peroxidation (2-Thiobarbituric acid reactive substances, TBARS) were evaluated. The current study revealed the impact of the sex and different developmental stages of the sea trout (parr, smolts, spawners, adults, and kelts) on the effective formation of adaptive oxygen-dependent mechanisms. A stable developmental-related tendency toward increased lipid peroxidation in muscle tissues was observed. Glutathione peroxidase in muscle tissues played a leading role in the different stages of trout development. A switch of the muscle cytosolic redox potential from the aerobic pathway to anaerobic glycolysis was observed. These results indicated that energy-related cellular components and metabolic enzymes could compensate for adaptive mechanisms without any serious damage to muscle tissues. The differences in the enzyme activities were associated with the reorganization of the energy-related metabolic pathways (anaerobic and aerobic pathways) during spawning. This process was one of the adaptation mechanisms of this fish.

Abstract
The aim of this paper was to report on an examination of the digestive organs in the deep-water fish Phycis blennoides (Brünnich) from Algerian coastal waters. A total of 1,019 specimens (5.7–62.7 cm in total length) obtained from commercial fisheries were examined between December 2013 and May 2017. The anatomical study was conducted using morphometric measurements of different sections of the digestive tract of P. blennoides. The histological features of the digestive tract were examined in the esophagus, stomach, intestine, and pyloric cecum. They were compatible with carnivorous feeding behavior and confirmed by a low intestinal quotient (IQ = 0.72 ± 0.13). The histopathological assessment highlighted the hepatic steatosis and parasitic infestation in its intestine from Anisakis simplex, which also occurs in Algerian coastal waters. According to our knowledge, this paper reports for the first time the morphohistological analysis of the digestive tract of a Phycidae species in Africa and provides the first histopathological assessment of the digestive organs of the greater forkbeard in the southwestern Mediterranean Sea.
