Arte & jóia: uma análise entre as jóias como objeto de arte e a arte contemporânea

More than seven thousand years of jewelry and track social progress, cultural and religious history of man, which always sought to produce objects to decorate and entice; satisfying their desires, building an art and meanings within their time. It experiencing these possible adornments that jewelry was being developed, each with its own characteristics and peculiarities. Currently, with the technology, trade and the need to search for new creations and concepts in the field jewelry, was prepared and developed those what we call art jewelry. This article specifies the time that they were the jewels of the author and tender and makes an analysis between jewelry as art and contemporary art.

A potencialidade da arte contemporânea ao transcender linguagens favorecendo a vida

Reflection about the contemporary production artistic, the own make artistic and the creative process that involve them it is noted that, comes to the poetic construction the action to greater understanding the being as artist and from the being while humanity. In current procedures that do not prioritize more materials, supports or languages for the production of works, but human being and his complexities, the art is manifested as the essence, need of renovation. From the documentary "Window of the Soul", directed by João Jardim and Walter Carvalho, and from personal creations is studied the transcendence of materiality in hybrids process, actions at resignify the look that investigates and reinterprets. In this exercise, art is justified as experience necessary, metaphors for the life, to teach us to see, fell and restructure us.

Eficácia da imunoterapia no tratamento de pitiose facial em equino

Background: Pythiosis in horses is a proliferative and ulcerative disease that primarily affects the skin and subcutaneous tissue of limbs, thoracic-abdominal region and head. This disease sometimes can also affect limb bones or cause tumoral masses in abdomen. Usually, the cutaneous cases are confused with habronemiasis. The disease is more common in marshy areas, places with formation of slow drainage ponds and aquatic vegetation under high temperatures. The aim of this study was to describe the development of facial lesions in a horse caused by pythiosis in Cuiaba, Mato Grosso, and, additionally to discuss relevant issues regarding the diagnosis, clinical course and response to immunotherapy treatment.Case: One five years old mare of unknown breed, created in property located in the Cerrado region, had a wound on its face difficult to be healed and non-responsive to several treatments based on ivermectin and organophosphate administrated by either topical or systemic via. The animal was assisted on the farm of origin by the veterinary team of the Clinical Medicine sector, of the Veterinary Hospital, Universidade Federal de Mato Grosso (HOVET-UFMT). on the occasion of the visit, which occurred 60 days after onset of signs, the animal showed a circular single large lesion, ulcerative with serous discharge on the right part of its face, between the eyes and nostrils. There were some necrotic foci with sinus, from which kunkers were extracted; a condition compatible with pythiosis. The diagnosis was confirmed by histology, ELISA and PCR.Discussion: Assuming pythiosis from data obtained from the survey and profile of the lesion (secretory aspect, emaciation and presence of sinus and kunkers), immunotherapy treatment was immediately applied. The advanced clinical aspects and the fact that early diagnosis and treatment are essentials to satisfactory therapeutic response were also taken into consideration for starting the treatment. The remission of signs was achieved after five subcutaneous applications with 14 days between each application. From the second application, it was observed clinical improvement and after 60 days of treatment there was almost complete remission of signs. The signs for a satisfactory response in the injury site followed the order of decreasing secretory aspect, decreasing borders, decrease the itching and bringing the edges together with the formation of a thin layer of crust on the surface. Pythiosis cases with lesions on the face and lower abdomen are commonly confused with habronemiasis by macroscopic and widespread similarity between technicians and attendants, and essential support to the diagnosis through laboratory tests, which in turn are still underutilized. In this case, the authors demonstrated the therapeutic efficacy of immunotherapy as an advantage, considering the possibility of applying it in cases of lesions in areas of difficult surgical access, treatment conditions in the field, with low cost and ease of application. Further studies approaching this alternative therapy are necessary, since side effects have been observed in some cases.

Pitiose cutânea equina de localização atípica tratada topicamente com solução de anfotericina B e DMSO

Background: Cutaneous lesions by Pythium insidiosum infection are commonly observed in horses, especially in those living at flooded environments. Equine pythiosis is characterized by the development of tumoral masses that are frequently located at distal limbs, ventral abdomen, thorax, breast and face. The lesions are usually granulomatous, serosanguineous and ulcerated, most often destroyed by self-mutilation due to the intense pruritus. The proposed treatment includes surgical excision followed by antifungal drugs administration, which can be done systemically or topically. Amphotericin B and dimethyl sulfoxide (DMSO) in association has been successfully used for cutaneous pythiosis topical treatment due to the DMSO property to carry any substance through plasmatic membranes.Case: The present report concerns a 12-year-old mixed breed gelding presenting with self-mutilation of a tumoral mass located at the left flank. The owners reported that the horse had initially presented a small wound that had evolved to a 20-cm in diameter mass in 4 weeks. Tissue samples were collected, processed and stained by the Gomori's methenamine silver (GMS) method. The histopathological analysis revealed Pythium insidiosum hyphae in a granulomatous tissue, especially located at peripheral region, where kunkers were present. Surgical excision of the mass followed by cauterization was indicated as initial treatment, and due to financial reasons, the owners elected only the topical antifungal therapy to control the fungus infection after surgery. Flunixin meglumine was also administrated for five days aiming the control of pain and inflammation. The wound was cleaned with povidone-iodine solution and rinsed with a solution containing, 50 mg, of amphotericin B in 10 mL of sterile water and 10 mL of DMSO. This procedure was carried Out twice a day. The wound healed fast due to an excellent centripetal epithelialization. and the horse was discharged after 64 days showing only 5% of the initial wound area. The owner reported by telephone the complete healing and hair growth 10 days after discharge.Discussion: Despite the atypical location of the tumoral lesion described at the present report, the history and clinical manifestations, especially the intense pruritus, showed similarity with other characteristic reports of equine cutaneous pythiosis. The diagnosis was confirmed by the histopathological examination showing hyphae structures, as described to be evidences of the presence of Pythium insidiosum in the tissue. The surgical procedure was the first step to provide remission of clinical signs, and one day after surgery the pruritus desapeared. After excision of the granulomatous tissue and cauterization, daily topical administration of amphotericin B associated with DMSO was effective in destroying the infectious agent, as observed by the excellent epithelization. A pink granulation tissue grew up providing an ideal surface for epithelial migration and the healing process progressed quickly. Centripetal epithelialization reduced the wound area until 3% of the initial area in 64 days of treatment, when the remaining wound was found almost completely healed and covered with hair. At the present report, the horse presenting pythiosis was only topically treated. The recommended therapy using amphotericin B and DMSO solution was effective, economically viable and low risk, considering that the systemic antifungal therapy usually suggested is expensive and extremely nephrotoxic. The atypical location of the lesion on the left flank shows that any anatomical region can be affected by the fungus, since the conditions for its development were present.

Alterações do padrão ultrassonográfico do parênquima testicular em bovinos jovens da raça Nelore

The ultrasononographic examination of testicles is a noninvasive and rapid method that, allied to clinical examination, can lead to an early diagnostic of testicles disorders. The aim of the present study is to enhance andrologic evaluation and to make public altered ultrasonographic testicular parenchyma pattern in young Nelore bulls. Testes of 114 Nelore bulls from 9 to 15 months old were submitted to ultrasonographic evaluation (Frontal and transverse planes of testes). In this group, 111 animals presented testicular parenchyma with uniform pattern at low echogenicity, and the testicular echogenicity increased in proportion to the animal's age. Three animals, from 9 to 15 months old, presented heterogeneous testicular parenchyma with multiple hyperechoics

Surgical treatment of gynaecomastia in a Saanen goat

Background: Gynaecomastia in male goats is characterized by abnormal development of the mammary gland. Enlarged udder may be observed cranially to the scrotum, which can occasionally reach the size of the testicles. The udder may carry functional glands and impair the animal's reproductive performance and welfare. The case of a successful surgical treatment of gynaecomastia in a high reproductive performance Saanen buck-goat is reported in the present study.Material, Methods & Results: The animal was admitted presenting significant augmentation of the mammary glands, which was clinically diagnosed as gynaecomastia. The male goat owned optimal phenotypic characteristics for the Saanen breed, which had been producing high performance descendents. The mammary glands had been impairing the goat's locomotion and sexual performance. Manual milking resulted in great amount of milk secretion. The animal presented anorexia and impaired sexual performance. After clinical and laboratorial evaluation, the animal was submitted to radical mastectomy. An elliptic skin incision was performed around each mammary gland. Subcuticular blunt dissection was accomplished to isolate the mammarian tissue from the abdominal muscular layer and the spermatic chord. The excised mass was sampled for histological assessment. Subcuticular layer and skin closure was carried in a routine fashion. Hygienization of the surgical wound was performed with 2,5% PVP-I solution for ten days. Additionally, an association of penicillin G benzathine and streptomycin, and fluxinin meglumine were also given. The surgical procedure was successfully accomplished without any peroperative complication. The excised mass was sampled for anatomic/histological assessment. Macroscopically, the left mammary gland presented 22 cm in length, 12 cm wide and 26 cm in diameter. The right gland presented 16 cm in length, 7 cm wide and 13,5 cm in diameter. The microscopic assessment revealed hyperplasia of the glandular ducts. No abnormalities resembling malignant mammary neoplasms or degeneration were observed. At the end of the treatment, the animal was completely recovered. The animal convalesced satisfactorily and surgical wound healed completely within the first 10 days post-op. The goat was not culled and returned to normal reproductive activity. Within 12 months of follow-up, the animal was able to produce high milk yield performance progenies.Discussion: This case report presented relevant aspects of the surgical management of gynaecomastia, especially to veterinary practitioners dealing with milk goats. Gynaecomastia is not as common as other reproductive disorders in domestic animals. In opposition to the findings of the present study, other trials revealed that gynaecomastia usually does not affect fertility, libido, ejaculate parameters and sexual performance of goats. However, it is important to consider that neoplasic disorders such as mammary adenocarcinoma may be present, even though these are rare complications. Last but not least, the decision making on mastectomy in the present study was crucial in order to reestablish the animal's welfare and its functionality in the farms reproduction program.

Efeito da idade sobre as principais características andrológicas de touros Brangus- Efeito da idade sobre as principais características andrológicas de touros BrangusIbagé criados extensivamente no estado do Mato Grosso do Sul - Brasil Ibagé criados extensivamente no estado do Mato Grosso do Sul - Brasil

Background: Bull fertility is extremely important for beef cattle production systems and has a multiplier impact on the economical and zootechnical indexes of the herd. Bulls raised in tropical conditions may present varied seminal characteristics due to, among other causes, different management practices and quality of pastures. Another factor that influences the semen characteristics is the age of the sire. The reproductive potential of bull evaluated through the andrological exam aims to ensure the semen quality and to improve the herd reproductive efficiency. The aim of this study was to evaluate the main semen parameters of Brangus-Ibage bulls extensively reared in eastern Mato Grosso do Sul state and to verify the effect of age on the andrological characteristics analyzed. It was also evaluated the correlation between age, scrotal circumference, and physical and morphological sperm characteristics produced by the Brangus bulls.Materials, Methods & Results: The study took place in the month of July 2010, during the routine andrological examination of 168 synthetic Brangus-Ibage bulls (5/8 Angus x 3/8 Nelore), belonging to the same property. For data analysis the animals were divided by age groups: animals younger than 4 years (Age I), animals between 4 and 8 years of age (Age II), and animals between 8 and 15 years of age (Age III). In another analysis, the animals were grouped according to the sperm motility pattern obtained from the semen collection: sperm motility lower than 40% (Motility I), sperm motility between 40 and 70% (Motility II) and sperm motility between 70 and 90% (Motility III). The results of the present study demonstrated an effect of age (P < 0.05) on the following androgical characteristics: scrotal circumference, ejaculate volume, sperm vigor, major defects, minor defects and total defects. It was also observed that the animals with higher sperm motility presented higher (P < 0.05) scrotal circumference, and lower (P < 0.05) percentages of major and total defects. Among the andrological characteristics evaluated in the present work, it was observed positive correlations between age and scrotal circumference (R =0.299; P =0.000), age and volume of ejaculate (R =0.161; P =0.037), age and major defects (R =0.188; P =0.015), sperm motility and scrotal circumference (R =0.245; P =0.001), sperm motility and sperm vigor (R =0.483; P =0.000), and between major defects and total defects (R =0.946; P =0.000). Also, negative correlations were observed between sperm motility and total defects (R =-0.372; P =0.000), sperm vigor and major defects (R =-0.498; P =0.000), and sperm vigor and total defects (R =-0.432; P =0.000).Discussion: Based on the results of this study it was concluded that the Brangus-Ibage bulls utilized for natural breeding in eastern Mato Grosso do Sul, Brazil, presented satisfactory semen quality taking into account the quality of the pastures where the animals were located. In addition, the scrotal circumference, the ejaculate volume, the sperm vigor, and the percentage of morphological characteristics were influenced by the age of the bulls. Therefore, considering the production system and the environmental conditions, the animals with age between 4 and 8 years were superior regarding the sperm parameters evaluated.

Efeitos da tricostatina A sobre a acetilação de histonas, proliferação celular e diferenciação de células tronco embrionárias murinas

Background: Embryonic stem cells are cells derived from early-stage embryos that are characterized by pluripotency and self-renewal capacity. The in vitro cultured murine embryonic stem cells can indefinitely propagate in an undifferentiated state in the presence of leukemia inhibitory factor (LIF). However, when stimulated, these cells can differentiate into cell lines derived from all three embryonic germ layers. The trichostatin A (TSA) is an epigenetic modifier agent and several studies have used the TSA to stimulate cellular differentiation. However, most of these studies only assessed one TSA concentration. Therefore, this study aimed to evaluate the effects of different TSA concentrations on histone hyperacetylation during in vitro cell differentiation of murine pluripotent embryonic stem cells, cultured with or without LIF, in the quest of to standardize their application on early cultures of embryonic stem cells.Materials, Methods & Results: Undifferentiated murine embryonic stem cells were plated in the presence of different TSA concentrations (0 nM, 15 nm, 50 nM and 100 nM) in the presence or absence of LIF. Thus, the treatments were evaluated in undifferentiated embryonic stem cells cultured in the presence of LIF (Control group: 0 nM LIF(+); Group 15 nM LIF+; Group 50 nM LIF+ and Group 100 nM LIF+), and in embryonic stem cells cultured in the absence of LIF (Control group: 0 nM LIF; Group 15 nM LIF(-); Group 50 nM LIF(-) and Group 100 nM LIF-). Treatment with TSA was performed for 24 h. After that the medium was replaced with fresh medium without TSA. Samples were collected at 0, 12, 24, 36 and 48 h after the beginning of the experiment. Three replicates were performed in each experimental group. The relative amount of Histone H3 lysine 9 acetylation was analyzed in all groups, as well as the cell proliferation in the embryonic stem cells cultured in the presence of LIF. In the control group (0 nM), the absence of LIF resulted in higher levels (P < 0.05) of H3lys9ac compared to the cultures supplemented with LIF. In the embryonic stem cells cultured in the presence of LIF, the 50 nM and 100 nM treatments resulted in higher levels (P < 0.05) of H3lys9ac when compared with 0 nM and 15 nM treatments. Evaluating the Hoechst area in the 0 nM group, it was observed that the number of cells increased (P < 0.05) according to the time of culture. Treatment with 15 nM also reflected a similar distribution, but the Hoechst area in 15 nM group was lower (P < 0.05) at 24 and 48h when compared to the observed in the control group. In the 100 nM treatment, was observed that the area of Hoechst was lower (P < 0.05) to that obtained in the control group at 12, 24 and 48h. In addition, it was observed that treatment with TSA induces greater cellular differentiation when compared to control groups in stem cells cultured in the presence of LIF as well as in the absence of LIF.Discussion: In the present study it was observed that TSA treatment increased the levels of histone acetylation in murine embryonic stem cells at a 50 nM concentration, making it possible to reduce the concentration recommended in the literature (100 nM). In addtion, it was concluded that the lower TSA concentrations utilized (15 nm and 50 nM) was less harmful to cellular proliferation than the 100 nM TSA concentration.
