Characterization of the SSAT1 gene and its expression profiling in various tissues and follicles in geese
Authors: Jiang Dongmei , Chen Ziyu , Yi Zhixin , Kang Bo 
Published: May 2018

Abstract
Spermidine/spermine N1-acetyltransferase (SSAT ) is a catabolic regulator of polyamines, ubiquitous molecules essential for cell proliferation and differentiation. In this study, the molecular characterization of the SSAT1 gene of the Sichuan white goose was analyzed, as well as its expression profiles in various follicles and tissues. The open reading frame of the SSAT1 cDNA (GenBank No. KM925008) is 516 bp in length and encodes a 171-amino acid protein with a putative molecular weight of 20 kDa. The predicted SSAT1 protein is highly conserved with those of other species, especially Gallus gallus. SSAT1 mRNA was ubiquitously expressed in all the examined tissues. The highest level of SSAT1 mRNA expression was found in the pineal gland (P<0.05), and was 12-fold greater than in the heart. The level of SSAT1 mRNA expression was relatively lower in preovulatory follicles, while it was higher in postovulatory follicles (POFs), particularly in POF1. Furthermore, as postovulatory follicles degenerated, SSAT1 expression gradually decreased. Our findings suggest that SSAT1 might play important roles in mediating the physiological function of the pineal gland and regulating the regression of POFs.

Abstract
The goal of the present study was to investigate the olfactory attractiveness of air-dried insects used as aromas to dogs. The trial consisted of 35 adult dogs (20 males, 15 females) aged between 12 months and 7 years (mean = 3.6), varied in terms of breed, kept as companion animals. The dogs had free olfactory access to selected unprocessed dried insects, i.e., mealworm (Tenebrio molitor), Turkestan cockroach (Shelfordella lateralis), black soldier fly (Hermetia illucens), and tropical house cricket (Gryllodes sigillatus), as well as commercial dried and pelleted dog feed, which was used as a control treatment. Samples (100 g) were located separately in non transparent closed boxes with 5 perforations in the cover (7 mm each) to improve the intensity of the aromas without direct contact with the tested samples. The box was recorded as chosen when the dog showed interest in it for more than 15 seconds continuously per each attempt (3 attempts per dog). The presented study shows that the selected insect species were chosen as frequently as the control group (P=0.03). However, in terms of preferences by dog gender, Tenebrio molitor was favored more often by males than by females, which preferred Shelfordella lateralis. The current preliminary data suggest that the olfactory features of the selected insect species may be attractive to dogs.
Colonization of hardwood and pine wood chips by mites (Acari), with particular reference to oribatid mites (Oribatida)
Authors: Klimek Andrzej , Chachaj Bogusław 
Published: May 2018

Abstract
The study was conducted in the years 2011–2012, in a forest nursery in Białe Błota (Bydgoszcz Forest District). The experiment was established in a 20 m wide belt of trees within a 110 years old stand growing on mixed fresh coniferous forest site. Litter bags containing hardwood and pine wood chips were placed on mineral soil of microplots and covered with a 5 cm layer of litter. The pattern of chips colonization differed between mites belonging to different orders. Predatory Mesostigmata colonized hardwood chips gradually but they were present in high numbers in pine chips from the beginning of the study. Abundance of Actinedida fluctuated within the two-year study cycle. Contrary to that, oribatid mites, which were a predominant mite type, colonized both types of chips gradually, while preferring the pine ones. At the end of the study, the structure of mite communities and mite abundance in pine chips were more similar to forest soil than in hardwood chips. The experiment demonstrated that pine chips provided most oribatid mites with more favorable living conditions than hardwood chips, as they were colonized at a quicker rate and by a greater number of species. The most abundant oribatid mite in both substrates was a eurytopic Tectocepheus velatus that showed no clear preferences towards either of the substrates. Majority of oribatid mites, e.g. Oppiella nova, Metabelba pulverulenta, Oribatula tibialis, Chamobates schuetzi, Galumna lanceata, preferred pine chips. The only species with clear preference for hardwood chips was Eniochthonius minutissimus. A comparison of usefulness of hardwood and pine wood chips in revitalization of degraded soils based on bioindication approach indicated higher suitability of pine chips that are also more available in Polish forests.
Flow cytometry – a modern method for exploring genome size and nuclear DNA synthesis in horticultural and medicinal plant species
Authors: Sliwinska Elwira 
Published: May 2018

Abstract
Flow cytometry (FCM) has been used for plant DNA content estimation since the 1980s; however, presently, the number of laboratories equipped with flow cytometers has significantly increased and these are used extensively not only for research but also in plant breeding (especially polyploid and hybrid breeding) and seed production and technology to establish seed maturity, quality and advancement of germination. A broad spectrum of horticultural and medicinal species has been analyzed using this technique, and various FCM applications are presented in the present review. The most common application is genome size and ploidy estimation, but FCM is also very convenient for establishing cell cycle activity and endoreduplication intensity in different plant organs and tissues. It can be used to analyze plant material grown in a greenhouse/field as well as in vitro. Due to somaclonal variation, plant material grown in tissue culture is especially unstable in its DNA content and, therefore, FCM analysis is strongly recommended. Horticultural species are often used as internal standards in genome size estimation and as models for cytometrically studied cytotoxic/anticancer/allelopathic effects of different compounds. With the growing interest in genome modification, increased application of FCM is foreseen.

Abstract
Strawberry trees (Arbutus unedo L.) are naturally grown in particular Black Sea and Mediterranean regions of Turkey with great diversity due to continuous seed propagation for centuries. The trees differ in terms of most of the horticultural characteristics. We investigated the phenolic compounds and the biochemical and pomological characteristics of the fruits of eight strawberry tree selections naturally grown in the western part of Turkey. Significant differences were found among the genotypes in terms of their phenolic compounds and their biochemical and pomological characteristics. Among soluble sugars, fructose (11.63 g 100 g−1) was the dominant sugar, followed by glucose (6.10 g 100 g−1) and sucrose (1.44 g 100 g−1) for all the genotypes. Positive correlation was found between fruit weight and soluble sugar content. Malic acid was the major organic acid (0.67-2.33 g 100 g−1), and the second major organic acid in strawberry tree fruits was citric acid (0.25-0.87 g 100 g−1). Vitamin C content was an average of 56.22 g 100 g−1 for the eight genotypes. Among phenolic compounds, gallic acid was dominant (1.62-7.29 mg 100 g−1), followed by chlorogenic acid (1.23-3.14 mg 100 g−1), on an average basis.

Published: May 2018

Abstract
Systems of anaerobic digestion should be used for processing of organic waste. Managing the process of anaerobic recycling of organic waste requires reliable predicting of biogas production. Development of mathematical model of process of organic waste digestion allows determining the rate of biogas output at the two-stage process of anaerobic digestion considering the first stage. Verification of Konto’s model, based on the studied anaerobic processing of organic waste, is implemented. The dependencies of biogas output and its rate from time are set and may be used to predict the process of anaerobic processing of organic waste.

Published: May 2018

Abstract
The casting technology is one of the oldest production technologies in the world but in the recent years metal additive manufacturing also known as metal 3D printing has been evolving with huge steps. Both technologies have capabilities to produce parts with internal holes and at first glance surface roughness is similar for both technologies, which means that for precise dimensions parts have to be machined in places where precise fit is necessary. Benchmark tests have been made to find out if parts which are produced with metal additive manufacturing can be used to replace parts which are produced with casting technology. Most of the comparative tests have been made with GJS-400-15 grade which is one of the most popular cast iron grades. To compare mechanical properties samples have been produced using additive manufacturing and tested for tensile strength, hardness, surface roughness and microstructure and then the results have been compared with the samples produced with casting technology. In addition, both technologies have been compared in terms of the production time and production costs to see if additive manufacturing is competitive with the casting technology. The original paper has been written in the Latvian language as part of the Master Thesis within the framework of the production technology study programme at Riga Technical University.

Abstract
Aim: To assess the clinical results after osteosynthesis with locked intramedullary nail in metastasis of the long bones. Material and methods. We designed a prospective study in which we included all the patients with metastasis of the long bones admitted and surgically treated in our department between 2013 and 2015. Data for 64 were available at the final check-up. Our cohort totalized a number of 69 fractures (2 long bones required surgical treatment in 5 patients). The mean follow-up for survivors was 37 months (limits: 18-49 months). The primary tumor was known in 51 patients (79,69%). For the remaining 13 cases (20,31%), the primary tumor was not known and the pathological fracture was the first sign of the malignant disease. In the last group, the tumor could be identified by imagistic methods in 6 cases, while in other 3 cases, a biopsy and histological examination (which were performed in all the remaining 7 cases) determined the source organ. Clinical and radiological check-ups were performed at every 3 months in the first year and at every 6 months after that. Results. Pain amelioration and mobilization of the involved limb were achieved in all the cases. In 3 patients, the osteosynthesis could not compensate the progressive bone loss and the permanent use of an external orthosis was mandatory. The survival rate was 82,81% at 6 months and 67,19% at 12 months. Conclusions. All patients could be mobilized. Two thirds of the patients will survive more than a year. The goals of osteosynthesis are the same, regardless the location of the fracture and implant used: pain amelioration, stability for immediate full weight bearing, durability for patient’s life expectancy.

Published: May 2018

Abstract
Introduction. Giant cell tumors of soft tissue (GCTs) have a relatively low incidence and their low prognosis is reserved to local relapses and distant metastases. This type of pathology usually affects adults and the elderly and it is localized in the extremities, most frequently in the thigh. Materials and methods. GCT is a relatively low aggressive tumor; approximately 85% of the patients survive at least 5 years after diagnosis. The risk factors for low prognosis are old age, metastases at the time of diagnosis, local relapse. We conducted this study in the University Emergency Hospital, Bucharest for a period of 3 years, between 01.01.2015 and 01.01.2018, which included 20 patients with ages between 22 and 83 years, of whom 9 were women and 11 were men. Results. Excision with safety margins was performed for all patients. During surgery, tissue samples from 6 different areas were sent for extemporaneous examination. After excision, the histopathological examination was performed and the diagnosis of GCT was established. Localized forms were described in 16 cases; diffuse forms were identified in 4 cases and loco-regional recurrences in 3 cases. Pre or postoperative adjuvant treatment was not applied in any of the cases. Conclusions. GCT is a rare, potentially malignant pathology, in which case evolution is unfavorable. From the clinical and imaging point of view, it is difficult to establish this diagnosis due to the large variety of pathologies it can be mistaken for, making biopsy an essential step within the diagnostic algorithm. Election treatment is represented by local excision with safety margins.

Published: May 2018

Abstract
Purpose. The periprosthetic fractures are a more and more often encountered type of pathology, in which the main problem is the indication for surgery. The most important thing is the choice of the best therapeutic option in order to get a solid fixation of the fracture and, in the end, to allow an early patient’s mobilization. Materials and method. 38 cases of periprosthetic fractures have been treated in the Orthopedics and Traumatology Department of University Emergency Hospital in Bucharest, between 2010 and 2016. International Vancouver classification was used for all cases. The osteosynthesis saving the femoral stem was preferred in 22 cases, as its stability was not affected. Stem revision was performed in 16 cases, as this was unstable due to the fracture. Acetabular component was also revised in 4 cases, as the PE insert presented severe wear. The patients were aged 52 to 84 years old and sex ratio M/ F = 13/ 25. Osteosynthesis was performed using Dall-Miles plates and molded plates, with braided cables or wire cerclage. Long stems, uncemented with or without distal locking, were used in 16 cases. Results. Postoperatively, the bone repair was efficient regarding the stability in most of the cases. The patients’ mobilization was early in most of the cases, except for the very old patients with associated comorbidities and limited biological resources. Conclusions. An appropriate surgical indication, adapted on each type of peri-implant fracture, leads to a good result, with early mobilization and the best consolidation of the fracture.

Published: May 2018

Abstract
Introduction. Due to the non-specific clinical findings and the reduced sensitivity of conventional radiography, soft tissue tumors (STT) were virtually unknown to radiologists until ultrasonography and computerized tomography were introduced. Because of its superior soft tissue contrast, multiplanar imaging capability, Magnetic Resonance Imaging (MRI) is the favored modality for the evaluation of soft tissue tumors. Purpose. MRI detection, characterization, and illustration of soft tissue tumors developed in the musculoskeletal system Material and method. The retrospective study refers to a group of 77 patients with suggestive clinical symptomatology for a soft-expanding process developed in the musculoskeletal system. Patients were examined according to a protocol that included complete clinical examination, two incidents radiographic examination, MRI, histopathological examination. The group consisted of 44 men (57%) and 33 (43%) women, aged between 7 and 80. Results. We presented the spectrum of identified types of tumors based on the MRI semiology elements (homogeneity and intensity of the signal in the native and post-contrast standard sequences, intra or extra compartmental localization, tumor size and shape), segmental location, and incidence relative to the histological type. Conclusions. Through high contrast resolution and the ability to acquire and display multiplanar, MRI is currently investigating choice in the detection and characterization of soft tumor tumors. The multiplanar images (axial, frontal, sagittal and oblique) provide complete data on the actual tumor extension, the appearance of vessels, nerves, bone segments, and adjacent joints to tumor formations, allowing the proper staging and appropriate therapeutic behavior.
A Review of 493 Radiographs of Domestic Dogs and Cats for Neoplasia and Neoplasia Suspicious Signs
Authors: Lescai D. 
Published: May 2018

Abstract
Cats and dogs are routinely diagnosed with different forms of neoplasia. One of the simplest imaging techniques is radiography. This way one can assess neoplastic extent affecting soft and bone tissue. 493 radiographs from 235 dogs and cats have been reviewed. 372 radiographs for 94 dogs, an average of 5.2 images for every dog and 121 radiographs for 48 cats, an average of 2.5 images for each cat were done. 27 relevant or suspect radiographs were done in dogs, for a total of 14 neoplastic subjects, corresponding to 6 relevant or suspect images for a total of 3 neoplastic processes in cats. This is translated into a proportion of 7.25% relevant or suspect radiographs in dogs and 4.95% in cats. It also means that 14.89% of the dogs that require radiographic examination and 2.47% of the cats are suffering or are suspicious for neoplastic disease. 5 out of 14 (35%) dogs had relevant radiographs for bone tissue neoplasia, 1 dog (7%) for muscular neoplasia and 4 dogs (28.5%) were suspicious for digital (mixed soft tissue/ bone tissue) neoplasia. 1 out of 3 cats had relevant images for muscular neoplasia and 2 cats for maxillary/ acetabular neoplasia.

Abstract
Background. Primary bone tumors are rare and affect especially young persons, being at the same time very aggressive and mutilating, often also implicating the disarticulation of the affected hip. That is why it is necessary to find alternatives of treatment, so that these young people to be able to keep their normal functionality and mental comfort. Objectives. The objective of this paper was to be able to offer a surgical treatment alternative to the hip disarticulation in case of malignant tumors of the proximal femur in young patients. Methods. We present the case of a 25-year-old female patient, who was hospitalized in our clinic for pain and functional impairment of the right hip. The clinical and radiological exams established the diagnosis of fracture of pathological bone of the proximal femur and it raised the suspicion of a tumor with malignant characters. We performed arteriography of the right inferior member, which showed a very good vascularized tumor, possibly vascular, localized to the proximal femur, arterially powered by the branches of right profunda femoris artery. We surgically intervened and made an incisional biopsy with anatomopathological exam, which established the diagnosis of osteosarcoma. Then, we practiced the segmental resection of the tumor, preceded by the embolization of the right femoral artery and after that the reconstruction with bipolar cemented modular prosthesis of the right hip. The patient had a favorable evolution, she did neuromotor rehabilitation, and then she presented to the oncologist for the initiation of adjuvant chemotherapy, which she followed conformably to the recommendations.

Abstract
Gestational trophoblastic diseases represent a heterogeneous group of disorders that arise from trophoblastic epithelium. Choriocarcinoma is a highly anaplastic malignancy derived from trophoblastic cells. It is characterized by the secretion of human chorionic gonadotropin and early hematogenous metastasis. Metastatic choriocarcinoma in bones is very rare. Gestational trophoblastic diseases can follow normal pregnancy, ectopic pregnancy, abortions or molar pregnancy. However, the presence of bone metastases in a young woman at reproductive age requires systematic assessment for a primary lesion, for 1-2 years. This paper aims to present the bone sites where these metastases can occur, as well as the review of literature supported by a pictorial essay.
