Abstract:
AbstractHomonymy and Ambiguity Phonetic in Mahalabiu. Homonymy is a form of wordsthat have different meanings but the pronunciation or spelling is the same andambiguity is the ability to express more than one interpretation. In this case, it isrelated to the ‘mahalabiu discourse’ which tends to have multiple meanings ineveryday language usage. The method used in this research is a descriptivequalitative method. Data collection techniques using interview techniques andrecording techniques. As for the object of research is the indigenous people of theBanjar tribe who live in the Alabio village. In ‘mahalabiu’, there are several formsof homonymy, namely: “maharakan, tarap, Langgar, Pagat, tinjak, maling, haur,dikalang, pusat, nyawa, dan kuitan”. In addition, there is also homonymy which ishomophony and homonymy which is homograph. (1) Homophony is the same soundbut different in writing and meaning, namely: “maharumi (maharu mi), kadada (kadada), dan anakutu (anakku tu)”;and (2) homography in ‘mahalabiu’ occurs as aresult of the unification of vocabulary in phonetic pronunciation, namely“bakicap”. Other than that,in ussing the word mahalabiu on average contains adouble meaning, this occurs due to the use of the word homonymy, while the contextin the conversation is not clear, resulting in inactivity.Key words: homonymy, phonetic ambiguity, mahalabiuAbstrakHomonimi dan Ambiguitas Fonetik dalam Bahasa Mahalabiu. Homonimi adalahbentuk kata yang memiliki makna yang berbeda tetapi pelafalan atau ejaannyasama dan ambiguitas adalah kemampuan mengekspresikan lebih dari satupenafsiran. Dalam hal ini berkaitan dengan mahalabiu yang cenderungmenimbulkan makna ganda dalam pemakaian bahasa sehari-hari. Metode yangdigunakan dalam penelitian ini ialah metode kualitatif yang bersifat deskriptif.Teknik pengumpulan data menggunakan teknik wawancara dan teknik rekaman.Adapun yang menjadi objek penelitian ialah masyarakat asli suku Banjar yangtinggal di desa Alabio. Dalam wacana mahalabiu terdapat beberapa bentukhomonimi, yaitu: “maharakan, tarap, langgar, Pagat, tinjak, maling, haur,dikalang, pusat, nyawa, dan kuitan”. Selain itu, ada pula homonimi yang bersifathomofoni dan homonimi yang bersifat homograf. (1) Homofoni merupakan bunyiyang sama tetapi berbeda tulisan dan maknanya, yaitu: “maharumi (maharu mi),kadada (ka dada), dan anakutu (anakku tu)”; dan (2) homografi dalam mahalabiuterjadi akibat dari penyatuan kosakata dalam pelafalan fonetik, yaitu “bakicap”.Selain itu, dalam pemakaian katamahalabiu rata-rata mengandung makna gandahal ini terjadi dikarenakan pemakaian kata homonimi, sedangkan konteks dalampercakapan tidak jelas sehingga muncul ketaksaan.Kata-kata kunci:homonimi, ambiguitas fonetik, mahalabiu

Abstract:
Homograft cardiac valves have been shown to have several advantages over conventional prosthetic valves. From October 1993 through November 1996, 273 homografts (262 valved and 11 non-valved) were used in various procedures at the All India Institute of Medical Sciences, New Delhi, India. The recommendations of the American Association of Tissue Banks were followed for procurement, harvesting, and storage of the valves. One hundred and ninety-six hearts were procured yielding a total of 439 homograft valves; 192 were pulmonary homografts, 187 were aortic homografts, and 60 were mitral homografts. Eighty-five homografts were used in the Ross procedure, 64 were used in homograft replacement of the aortic valve, 28 were used in replacement of the mitral valve, 85 were used in various operations for heart disease as valved conduits, and 11 homografts were used as either non-valved conduits or for patch repair. One hundred and thirty-five homografts (31%) were discarded for various reasons. Our early experience of valve banking is discussed.

Abstract:
We review our experience from January 1987 to September 1992 with the surgical treatment of complex congenital malformations requiring an extracardiac homograft-valved conduit. There were 10 patients in the series; 7 pulmonary and 3 aortic homografts were implanted. Ages ranged from 1 month to 26 years (mean 7.9). There were 4 cases of hospital mortality, none related to the homograft itself. The major postoperative complication was low cardiac output syndrome. The 6 survivors have been followed between 3 months and 5 years and no dysfunction of the valved homograft, thromboembolism, or hemolysis have been recorded. All the survivors are symptom-free with a good quality of life. The use of homografts is advised in selected cases of right and left ventricular tract reconstruction for congenital heart disease; homografts are easy to handle and offer several technical advantages over prosthetic tissues.

Abstract:
Background: To evaluate homograft implantation for the urgent treatment of vascular infections on the basis of the course of infection using microbiological findings in perioperatively obtained specimens and during homograft processing. Patients and methods: 85 patients were treated with cryopreserved homografts from 2004-2007. The microbiological findings of the decontamination process of homografts in the tissue bank were evaluated. The perioperative infection profile (microorganisms, CRP, leukocytes, body temperature) of the patients was analysed. Results: Complete microbiological and clinical follow-up for the postoperative course was available for 35 patients, who were treated with homografts from the same tissue bank and finally included into this study. 55 cryopreserved homografts were implanted. 35 / 55 (64 %) homografts were positive for microorganisms before decontamination. 3 / 35 (9 %) homografts remained positive after the decontamination. 33 patients were operated for prosthetic graft infection and 2 for an infiltration of a large vessel from neighbouring malignant disease. The most common infection agent was Staphylococcus aureus. Thirty-day mortality was 20 % (7 / 35). Only in 4 / 35 (11 %) patients were the microorganisms of the intraoperative swabs also detected during the postoperative course. The microorganisms were ORSA, Enterococcus faecium, Enterobacter aerogenes and Burkholderia cepacia. The patient with ORSA infection died on POD 11 from multiple organ failure and all other patients recovered. None of the postoperative swabs showed the homograft predecontamination microorganisms. Interestingly, a significant association (P = 0.003) between C-reactive protein increase two weeks after surgery and donor-recipient ABO mismatch was found. Conclusions: The implantation of homografts following the established decontamination is an alternative urgent therapeutic option in vascular infections with encouraging outcomes. The absence of the predecontamination focus in the postoperative specimens of patients, suggests that the postoperative course and outcomes show no strong relation to potential homograft contamination prior to the decontamination process.

Abstract:
Homograft vascular replacement is almost as old as vascular surgery itself. Gross and Dubost are credited as the first authors who clinically attempted vascular reconstruction using biological tissue of human origin. The advent of synthetic vascular prostheses together with the complexity of logistics in procuring, preserving, and storing vascular homografts made the routine use of vascular homografts impractical. Cryopreservation techniques have strongly influenced the use of biological tissue. The tireless work of a few authors has enabled us to better understand the behavior of homograft tissues in cardiovascular surgery. Homograft replacement of the aortic and pulmonary valves is now a recognized way to treat a number of conditions of the aortic root and the right ventricular outflow tract. Renewed interest in the use of cryopreserved homografts in cardiac surgery has led us to expand our own indications for their use. As our Cryopreservation Unit is fully operative, we also have vascular homografts available for implantation. Here we describe the extended use of vascular homografts in extraanatomic aortic bifurcation bypass in a patient with previous multiple vascular operations. To use the ascending aorta as the inflow source in cardiovascular reconstruction has been previously described; however, it has not been popular among surgeons. Robicsek termed this type of bypass graft “very long” aortic grafts, and we recently had the chance to use fully biological tissue of human origin for this type of reconstruction.

AbstractObjectivesTo evaluate the results of balloon dilatation of stenotic homografts in children, adolescents, and young adults and to identify factors that might influence or predict the effect of the dilatation.BackgroundHomografts are widely used in congenital cardiac surgery; however, the longevity remains a problem mostly because of stenosis in the homograft. The effect of treatment by balloon dilatation is unclear.MethodsIn a retrospective study, the effect of balloon dilatation was determined by the percentage of reduction of the peak systolic pressure gradient over the homograft during catheterisation and the postponement of re-intervention or replacement of the homograft in months. Successful dilatations – defined in this study as a reduction of more than 33% and postponement of more than 18 months – were compared with unsuccessful dilatations in search of factors influencing or predicting the results.ResultsThe mean reduction of the peak systolic pressure gradient was 30% in 40 procedures. Re-intervention or replacement of the homograft was postponed by a mean of 19 months. In all, 14 balloon dilatations (35%) were successful; the mean reduction was 49% and the mean postponement was 34 months. The time since homograft implantation, the presence of calcification, the homograft/balloon ratio, and the pressure applied during dilatation all tended to correlate with outcome, but were not statistically significant.ConclusionsBalloon dilatation is able to reduce the peak systolic pressure gradient over homografts in a subgroup of patients and can be of clinical significance to postpone re-intervention or pulmonary valve replacement.

Abstract:
AbstractHomografts have long been used for right ventricular outflow tract (RVOT) reconstruction. Tissue banks struggle to meet the clinical demand of tissue, with insufficient donor availability and strict recommendations on tissue quality with high proportions of discards. This study analyzes the long-term outcome of patients receiving a homograft with small fenestrations of the cusps or other structural changes, to evaluate if minor impairment of the homograft affects the durability. Homograft characteristics and patient outcome were described. Follow-up was maximum 24 years. Structural changes of the homografts were analyzed in relation to patient outcome, using univariable and multivariable Cox proportional hazard regression. Between 1995 and 2018, 468 patients received 535 homografts in the RVOT in Lund. Median recipient age was 13 years. There were 137 (26.9%) reinterventions. Freedom from reintervention was 75.8% (95% CI 71.3–79.7%) at 10 years and 57.4% (95% CI 50.0–64.0%) at 20 years. Small fenestrations of the cusps, fibrosis of the cusps and minor atheromatosis of the vessel did not show any statistically significant impact on long-term outcome, hazard ratio = 0.46 (95% CI 0.11–1.87, p = 0.276) and hazard ratio = 0.80 (95% CI 0.25–2.56, p = 0.704). Minor structural changes of the homografts seem to be acceptable without affecting the long-term durability.

The excision of an infected aortobifemoral Dacron graft 9 years after implantation and bilateral axillofemoral Dacron bypass reconstruction led to reinfection of the extra-anatomic bypass grafts. A new aorto-bifemoral reconstruction was performed using cryopreserved homografts delivered by the European Homograft Bank in Brussels and both axillo-femoral prostheses were removed. No signs of infection and no alterations of the homografts can be detected 3 years later.

Abstract:
Objective Surgical management of aortic valve infective endocarditis (IE) with cryopreserved homograft has been associated with lower risk of recurrent IE, but there is equipoise with regard to the optimal prosthesis. This systematic review and meta-analysis were performed to compare outcomes between homograft and conventional prosthesis for aortic valve IE. Methods We searched MEDLINE database to September 2017 for studies comparing homograft versus conventional prosthesis. The main outcomes were all-cause mortality, recurrent IE, and reoperation. Results There were 18 included comparative observational studies with 2232 patients (median follow up = 5 [interquartile range: 2–7] years, 30% prosthetic valve endocarditis); four studies were adjusted for baseline differences. There were no differences in perioperative mortality or stroke despite a greater proportion of staphylococcal endocarditis, abscess, and root replacements but less multivalve involvement in the homograft group. Long-term outcomes of all-cause mortality [incidence rate ratio (IRR) = 1.03, 95% confidence interval (CI) = 0.81–1.31, P = 0.83, for unmatched, and IRR = 0.82, 95% CI = 0.36–1.84, P = 0.63, for matched studies], recurrent endocarditis (IRR = 1.01, 95% CI = 0.53–1.93, P = 0.96, for unmatched, and IRR = 1.04, 95% CI = 0.49–2.19, P = 0.92, for matched studies), and reoperation (IRR = 1.60, 95% CI = 0.80–3.21, P = 0.18, for unmatched, and IRR = 3.17, 95% CI = 0.52–19.44, P = 0.21, for matched studies) were not different comparing homograft versus conventional prosthesis. There was a significantly increased need for reoperation with homograft versus mechanical prosthetic valves, but this comparison was based on limited data. Conclusions Homografts and conventional prostheses offer similar survival and freedom from recurrent endocarditis and reoperation for aortic valve IE. Homografts may be associated with greater risk of reoperation compared with mechanical valves.

Abstract:
The use of homografts in ossiculoplasty has been well documented in the literature. In the early 1980s, nonossicular homograft otic capsule bone was used as a prosthetic material in stapedectomy. We began using homograft femur as a prosthetic material in the early 1990s. In this article, we report the results of a retrospective study of the use of homograft femur prostheses. A series of 300 stapedectomies was performed between Aug. 24, 1992, and Jan. 20, 2000. Total footplate removal with preservation of the posterior crus was our procedure of choice. However, in 116 of these cases, the posterior crus could not be used, and a homograft femur prosthesis was substituted. For these prostheses, all homograft femurs were obtained from the American Red Cross. All prostheses were prepared in the bone laboratory and stored in the bone bank until needed. After an adequate period of follow-up, we tabulated our results. We found that in 89 of 113 cases (78.8%) available for follow-up, the air-bone gap was completely closed. In addition, the air-bone gap was closed to within 5 dB in 11 patients (9.7%) and closed to within 10 dB in five patients (4.4%). In all, 105 of the 113 homograft femur prosthetic procedures (92.9%) resulted in a successful outcome.

Abstract:
Medfödda hjärtfel drabbar ca 1% av alla barn. Vid vissa typer av hjärtfel saknas adekvat förbindelse mellan höger kammare och lungartären, antingen pga stenosering, obstruktion eller total avsaknad. Dessa hjärtfel krävs operation i form av rekonstruktion av förbindelsen (RVOT). För rekonstruktionen används vanligen mänskliga hjärtklaffar, så kallade homograft. Homograft används fördelaktigt pga dess goda hemodynamiska prestanda samt att mottagaren besparas behandling med blodförtunnande mediciner. Syftet med projektet var att genomföra en hållbarhetsstudie av homograft som bevarats i antibiotikalösning över tid, tidsintervall upp till två månader. Vilket besvaras utifrån hur homograftet cell- och vävnadsstruktur påverkas av antibiotikalösningen, och om det skiljer sig mellan aorta- och pulmonaliskärl samt om och hur homograftets mottaglighet för histologisk infärgning påverkas av antibiotikalösningen över tid? Studien omfattade kärlmaterial från både aorta- och pulmonaliskärl från 20 donerade homograft, där samtliga donatorer är upp till 65 år och har samtyckt till att homograften används till studien. Kärlmaterialet processas morfologiskt och färgas in med histofärgerna Azan, Erytrosin-Saffran samt Van Gieson Elastin för att visualisera kärlväggens cell- och vävnadsstrukturer. Resultat av studien påvisar att homograften påverkas negativt av antibiotikalösningen över tid med avseende på cell- och vävnadsstruktur. Det går även att påvisa adekvata skillnader i hur aorta- och pulmonaliskärlen påverkas. Däremot påvisades ingen signifikant antbiotikapåverkan med avseende på homograftets mottaglighet för histofärgningarna.

Abstract:
Micrografting was used to study the restoration of symplasmic transport at the graft union and to examine the long-distance transport of macromolecules between scion and rootstock. New techniques were established, such as correlative imaging and single-cell analysis in microfluidic devices, to study graft development both in vivo and in vitro. Imaging of Arabidopsis homografts showed that a symplasmic domain develops in the callus stele whose function may be to contain the spread of auxin into the surrounding ground tissue. It was demonstrated, also, that recent reports of organelle transfer at the graft union cannot be explained by the formation of secondary plasmodesmata (PD) at the graft interface. While fused calli did not exchange organelles in vitro, large aggregates of the SIEVE-ELEMENT OCCLUSION RELATED protein fused to YFP (SEOR-YFP; 112 kDa) were unloaded from mature sieve tubes into living cells of the graft partner in vivo, suggesting that vascular remodelling may be a prerequisite for the exchange of organelles at the graft interface. Fusion proteins expressing organelle-targeting signals were found to translocate across the graft junction, unloading into cell files adjacent to the root protophloem. The phloem mobility of a given fusion protein was assessed using bioinformatic and statistical analysis of publicly available data. The size of a protein and its relative abundance in CCs both emerged as defining factors for subsequent phloem transport. The recipient tissue for phloem-unloaded macromolecules was identified as the phloem-pole pericycle (PPP). This cell layer is required to remove macromolecules from the terminus of the protophloem. Induced callose deposition at the PD that connect protophloem SEs to the PPP caused a restriction in unloading and a subsequent arrest in root growth. A non-cell autonomous protein of CC origin, NaKR1-1, is proposed to affect the unloading of macromolecules either by increasing the size exclusion limit (SEL) of PD within the PPP or by enabling a build-up in pressure at the protophloem terminus, due to SUC2 activity, thus allowing phloem unloading.

Abstract:
Clinical transplantation continues to rely on the use of non-specific immunosuppressive therapy, which reduces the incidence of graft rejection but also carries with it undesirable side effects such as infection and malignancy. A preferable option would be to induce operational graft tolerance without the need for such non-specific therapy, for example by harnessing natural mechanisms. In recent years there has been much progress in the characterisation of CD4<sup>+</sup> cells that possess suppressive or regulatory properties in experimental systems; particular attention has been focussed upon CD4<sup>+</sup> cells expressing CD25, the α subunit of the IL-2 receptor, which have been shown to possess regulatory capacity both in vitro and in vivo in autoimmune disease and transplantation models. The aim of this study was to examine the potential role of CD4<sup>+</sup>CD25<sup>+</sup> regulatory T cells (Treg) in the induction phase of tolerance in a transplantation model. Pre-treatment of mice with fully allogeneic blood administered under the cover of anti-CD4 antibody is shown to lead to the generation of CD4<sup>+</sup>CD25<sup>+</sup> cells capable of preventing the rejection of donor type, but not third party, skin allografts mediated by CD4<sup>+</sup>CD45RB<sup>high</sup> cells in secondary recipients. In addition to their suppressive properties in vivo, these CD4<sup>+</sup>CD25<sup>+</sup> cells also display the ability to regulate the proliferation of target T cell populations in vitro. Generation of CD4<sup>+</sup>CD25<sup>+</sup> Treg by the pre-treatment protocol is not reliant upon an intrathymic selection process nor upon the expansion of a pre-existing CD4<sup>+</sup>CD25<sup>+</sup> Treg population, but can occur through the conversion of peripheral CD4<sup>+</sup>CD25<sup>-</sup> cells to a regulatory phenotype. Although the regulatory function of the CD4<sup>+</sup>CD25<sup>+</sup> cells generated by pre-treatment is donor strain-specific in vivo, this specificity can be overcome by activating the cells before their regulatory capacity is tested. Moreover, CD4<sup>+</sup>CD25<sup>+</sup> cells generated by pre-treatment with a non-cellular protein antigen completely unrelated to the graft can also regulate skin allograft rejection provided that these Treg are first activated. It is hoped that the principles defined by these findings identify a strategy that may be applicable in clinical transplantation and in the therapy of autoimmune disease.

Abstract:
Este artigo aborda os problemas da estimação da homografia e da servovisão rápidas baseadas em intensidade dos pixels. Inicializações clássicas das respectivas otimizações não lineares de tempo real dependem de correlações de imagens ou assumem pequenos deslocamentos entre elas. Um novo observador linear da homografia é proposto e aplicado neste trabalho para inicializar aquela otimização sem nenhuma dessas dependências. Para servovisão, outro novo observador linear é então derivado do primeiro e aplicado para desacoplar diagonalmente a dinâmica do erro de controle. Uma dinâmica diagonal pode reduzir drasticamente os tempos de resposta e melhorar o desempenho do sistema. Ambos observadores propostos não são baseados em linearizações e são analisados usando a teoria de Lyapunov. Resultados com um braço robótico de 6 GdL confirmam experimentalmente a eficácia da abordagem de estimação da homografia e servovisão de alta velocidade baseadas em intensidade.

Abstract:
Although existing valve prostheses generally have resulted in enhanced survival and quality of life, they have serious drawbacks that limit their long-term efficacy. These include thrombo-embolic complications requiring lifelong anticoagulation in case of mechanical valves, limited durability due to calcification and structural failure in case of bioprostheses and structural deterioration and shortage of donor material when using a homograft. In addition, the inability to grow restricts the application of currently available prostheses in pediatric patients. Heart valve tissue engineering (TE) is a promising alternative to create living valves that may have the capacity to grow and remodel. The traditional TE approach requires the growth of tissue on a scaffold in a bioreactor before implantation (1).
