The Role of Tibial Osteotomy in the Outcome of Meniscus Allograft Transplantation
Authors: Myers Peter , Mahmoud Ahmed , Young Jamie
Published: May 2017

Objectives:

Meniscal allograft transplantation (MAT) is indicated to relieve pain and improve function and hopefully to delay the onset of osteoarthritis in patients with meniscus deficiency. The purpose of this study was to compare the effect of perioperative cartilage status on survivorship and whether this is influenced by a concurrent tibial osteotomy.

Methods:

We reviewed a consecutive series of 45 MATs in 42 patients with a minimum post-surgical time of four years. Patients were divided into two groups using the Outerbridge Cartilage Score (OSC) to group 1 (minimal cartilage damage of grade 0-2) and group 2 (severe cartilage damage of grade 3-4). Pre- and post-operative outcome scores were collected using the Lysholm, Tegner, Oxford Knee Score (OKS) and International Knee Documentation Committee (IKDC) subjective knee form. Survival end points were transplant removal and knee arthroplasty.

Results:

The mean post-surgical follow-up for patients in group 1 (n=14, age 32.0 +/- 9.8) and group 2 (n=31, age 36.2 +/- 10) was 10.6 years (SD +/-3.35) and 7.1 (SD+/-3.34) respectively. There was no significant difference in the mean age between the two groups (p-value 0.221, CI -2.62 to 11). Patients in group 1 demonstrated no failures of the MAT over the time frame evaluated. Group 2 (n=31) had a 74.2% survival of MATs. The clinical outcomes improved in all groups with no significant difference between group 1 and group 2. Those patients in the osteotomy group did not have a statistically significant different survival (Mantel-cox test p-value of 0.922) or clinical outcome.

Conclusion:

Patient with minimal cartilage status have improved MAT survivorship but both groups benefit clinically. Tibial osteotomy, when indicated, does not influence the outcome of MAT.
Creation of an Australian Osteotomy Knee Registry Datasheet Instrument using a Modified Delphi Method
Authors: Vertullo Christopher J.
Published: May 2017

Background:

In 2015, the Australian Knee Society(AKS) agreed to initiate and fund an Australian Knee Osteotomy Registry (AKOR) in 2015 in conjunction with the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR). A concise and robust dataset was required to proceed to AKOR preliminary site trialing.

Study Design:

Modified Delphi consensus building.

Methods:

Seven participants who were orthopaedic surgeons, AKS members and AKOR working group members performed a four round modified Delphi consensus building electronic non-blinded questionnaires using Google Sheets, a cloud-based spreadsheet. Round 1 involved the attribute rating using 0-10 of surgeon assessed utility of 41 initial datasheet instrument questions with 168 stem options. Surgeons could comment on each question or stem, giving comments on their rating and or proposing new variations or additions. Round 1 questions were based on the Swedish HTO Registry dataset with additional questions from surgeon interview. Questions and or stems with a mean utility rating of less than 2 were excluded. Questions and or stems with a mean utility raking of 8 or greater were accepted. Questions and or stem with a mean utility ranking of between 8 and 2 were included in subsequent rounds. Surgeons comments and votes were non-blinded. New or alternative questions or stems could be proposed by any surgeon during the process and voted on in the next round. This process was repeated until dataset consensus was achieved.

Results:

A final dataset of 32 questions was created after 4 rounds. Consensus was reached on the following items; patients demographics, hospital, state, surgeon’s code, date, primary or re-operation, diagnosis at primary procedure, diagnosis at re-operation, type of primary osteotomy, type of re-operation, form of fixation, bone graft, coincidental surgery, approach to correction calculation, pre-operative status of ACL, pre-operative status of PCL, previous knee surgery, preoperative mechanical axis, planned post-operative mechanical axis, preoperative fixed flexion deformity, pre-operative Ahlbäck grading of knee OA. Questions that had a final utility rating less than 10 included; coincidental surgery, approach to correction calculation, pre-operative Ahlbäck grading of knee OA, planned post-operative mechanical axis and preoperative fixed flexion deformity.

Conclusion:

The final AKOR dataset requires pragmatic validation prior to nation-wide implementation. Questions with low final attribute rating may not be included in the final instrument after validatation.
Results of medial patella stabilization surgery at 11-14 years, with realignment surgery according to an algorithmic approach
Authors: Paterson Roger , Balasubramaniam Pradeep
Published: May 2017

Objectives:

To report long term outcomes of patella stabilization surgery, and describe an algorithmic approach to realignment and other ancillary surgery

Methods: Retrospective observational series

All 49 consecutive cases of medial retinacular plication, usually with Medial Patello-Femoral Ligament (MPFL) reconstruction using a redundant local graft, for patella instability, by a single surgeon from 2001 to 2005 were sent a questionnaire, and followed up by phone. Realignment and other surgery was included as indicated by the senior author’s algorithmic criteria. Nine patients were not contactable, and four chose not to participate, leaving 29 patients with 35 operated knees who are the subject of this study.

Results:

Tegner-Lysholm scores were 77% excellent or good (mean 90 +/− 10, 61-100). Kujala scores were: mean 90 +/− 13, 34-100. The re-dislocation rate was 11% (4 knees, 2 of 9 after plication without MPFL reconstruction). Five knees had further surgery (3 revisions, 1 loose body, 1 arthrofibrosis). The worst results were in those who first came to surgery before skeletal maturity, with 6 of those 10 having fair or poor final outcomes. Only two others had fair or poor results.

Conclusion:

Chondral damage at a young age was the key factor contributing to poor results. At minimum 11 year follow-up, the re-dislocation rate after MPFL reconstruction, (plus re-alignment as indicated), was 2 of 26 (8%). A redundant local graft, with zero donor site morbidity, is adequate for reconstruction of the MPFL, which is more reliable than plication alone, even when the MPFL is felt to have a sound femoral attachment.
Injury Prevention at North Queensland Cowboys 2012 - 2015
Authors: Maguire John
Published: May 2017

Objectives:

Review injury rates at North Queensland Cowboys and compare this to the league in general and finishing position.

Methods:

Injury statistics and surveillance body. Review shoulder and knee injury statistics from 2012 – 2016. Comparisons to rest of the competition and finishing position for the various seasons.

Results:

It has long been thought that to win premierships, injury rates are important. In 2012 North Queensland Cowboys finished in eight position. The injury rates at this time were high. 2011 signify high injury rates which led us to introduce prevention strategies for knee and shoulder injury based on FIFA 11+ format. There has been a significant decline in injury rates such that by 2015 we had the least injuries in the competition. This corresponds to finishing the season as premiers. During this period the only significant knee injuries occurred in players that were new to our system.

Conclusion:

The injury prevention strategies have worked well at our club. Significantly reducing our serious injury rates.
Comparison of Outcomes between Hamstring Autograft and Synthetic (LARS) ACL Reconstructions
Authors: Woods K.R. , McGrath T.M. , Waddington G. , Scarvell J.M. , Ball N. , Adams R. , Creer R. , Smith D.
Published: May 2017

Objectives:

This study compared the short term (24 month) clinical outcomes in a prospective, comparative case series of participant selected hamstring autograft and synthetic (LARS) ACL reconstructions.

Methods:

64 ACL reconstructed participants (32 hamstring,32 LARS), completed a “goal-oriented” rehabilitation protocol. They were assessed for joint laxity (KT1000), clinical outcome (IKDC Knee Examination) and activity (Tegner Activity Scale-TAS) pre-operatively and at 12,16,20 and 24 weeks, and at 12 and 24 months post-operatively.

Results:

KT 1000 results did not differ significantly between the 2 treatment groups at 24 months. Differences were noted in joint laxity measurements between the 2 groups at varying time points. The LARS group had immediate stability of the joint at 12 weeks followed by a gradual increase in laxity over the follow-up period, while the hamstring group showed an increase in laxity up to 16-20 weeks, followed by a gradual decrease over the follow-up period. The LARS group had significantly higher TAS scores in the early post-operative period, but there was no significant difference between the 2 groups at 12 months and beyond. At 24 months, 32 of the hamstring group and 30 of the LARS group achieved IKDC Scores “A” or “B”. There were 5 reported graft failures (15.6%) in the LARS group between 7 and 22 months post-op, and none in the hamstring group.

Conclusion:

ACL reconstruction using synthetic (LARS) grafts produced earlier return of some activities compared to autograft reconstructions, but this difference was no longer evident by 12 months post-op. When the substantially differing failure rates are taken into consideration, this early benefit does not appear to justify their use in place of autografts for ACL reconstruction.

Authors: Robinson Mr Tony , Robertson Ms Tracy
Published: May 2017

Objectives:

This paper will look at the incidence of Total Knee Replacement in patients over the age of 50 years over an 8 year period. All patients had a symptomatic medial meniscal tear and moderate bi-compartmental osteo-arthritis.

Hypothesis:

Incidence of Total Knee Replacement in these patients increases with age and length of follow up.

Methods:

A total of 411 patients met this criteria with 357 contactable by telephone. Patients were asked regarding Total Knee Replacement and other surgical intervention.

Results:

Of the total of 357 patients contacted, 78 (22%) patients were referred for Total Knee Replacements over this 8 year period.

Conclusion:

The incidence of Total Knee Replacement correlates with age but not with follow up.

Improving End-of-Life Care: Palliative Care Embedded in an Oncology Clinic Specializing in Targeted and Immune-Based Therapies
Authors: Einstein David J. , DeSanto-Madeya Susan , Gregas Matthew , Lynch Jessica , McDermott David F. , Buss Mary K.
Published: May 2017

Purpose:

Patients with advanced cancer benefit from early involvement of palliative care. The ideal method of palliative care integration remains to be determined, as does its effectiveness for patients treated with targeted and immune-based therapies.

Materials and Methods:

We studied the impact of an embedded palliative care team that saw patients in an academic oncology clinic specializing in targeted and immune-based therapies. Patients seen on a specific day accessed the embedded model, on the basis of automatic criteria; patients seen other days could be referred to a separate palliative care clinic (usual care). We abstracted data from the medical records of 114 patients who died during the 3 years after this model’s implementation.

Results:

Compared with usual care (n = 88), patients with access to the embedded model (n = 26) encountered palliative care as outpatients more often ( P = .003) and earlier (mean, 231 v 109 days before death; P < .001). Hospice enrollment rates were similar ( P = .303), but duration was doubled (mean, 57 v 25 days; P = .006), and enrollment > 7 days before death—a core Quality Oncology Practice Initiative metric—was higher in the embedded model (odds ratio, 5.60; P = .034). Place of death ( P = .505) and end-of-life chemotherapy (odds ratio, 0.361; P = .204) did not differ between the two arms.

Conclusion:

A model of embedded and automatically triggered palliative care among patients treated exclusively with targeted and immune-based therapies was associated with significant improvements in use and timing of palliative care and hospice, compared with usual practice.
Handling Knowledge: Holy Bodies in the Middle English Mystery Plays
Authors: Cushman H. M.
Published: May 2017

The representations of the midwife Salome and the Apostle Thomas in the N-Town and Chester plays complicate the relationship between two modes of knowledge: “clergie” or male clerical learning, on the one hand, and knowledge derived from sensory experience on the other. The plays expose clerical learning's dependence on and proximity to lay experiential knowledge. In doing so, they resist the dichotomies that structure other accounts of these figures and demonstrate how theological knowledge does not rest exclusively in any one set of hands. Knowledge, instead, is made manifest at the point of contact between clerical learning and physical experience. The drama empowers its nonclerical audience to test and “assay” in the form of dramatic “experiments” the theological knowledge that structures their religious lives, and thus invigorates the audience's investment in that knowledge.
Living with a leaky skin: upregulation of ion transport proteins during sloughing
Authors: Wu Nicholas C. , Cramp Rebecca L. , Franklin Craig E.
Published: May 2017

Amphibian skin is a multifunctional organ providing protection from the external environment and facilitating the physiological exchange of gases, water and salts with the environment. In order to maintain these functions, the outer layer of skin is regularly replaced in a process called sloughing. During sloughing, the outermost layer of the skin is removed in its entirety, which has the potential to interfere with skin permeability and ion transport, disrupting homeostasis. In this study, we measured, in vivo, the effects of sloughing on the cutaneous efflux of ions in toads Rhinella marina kept in freshwater conditions. We also measured transepithelial potential, cutaneous resistance, active ion transport and the distribution, abundance and gene expression of the key ion transport proteins sodium–potassium ATPase (NKA) and epithelial sodium channel (ENaC) during sloughing. We hypothesised that the increase in transepithelial efflux of ions during sloughing is a consequence of increased permeability and/or a reduction in the abundance or expression of cutaneous ion transport proteins, resulting in disruption of internal ion homeostasis. There was a significant increase in sodium and chloride efflux during sloughing in R. marina. However, although in vitro skin resistance decreased after sloughing, active sodium transport increased commensurate with an increase in NKA and ENaC protein abundance in the skin. These changes in skin function associated with sloughing did not affect the maintenance of internal electrolyte homeostasis. These results suggest that during sloughing, amphibians actively maintain internal homeostasis by increasing cutaneous rates of ion uptake.
High Performance Anode for Direct Cellulosic Biomass Fuel Cells Operating at Intermediate Temperatures
Authors: Hibino Takashi , Kobayashi Kazuyo , Lv Peiling , Nagao Masahiro , Teranishi Shinya
Published: May 2017

Cellulosic biomass resources have considerable potential as a renewable energy source that can be used for the cogeneration of electricity and heat. The utilization of these resources generally requires three major systematic processes: gasification, gas processing, and gas utilization. If a power generator could operate using wood resources directly as fuels, then this system could be significantly simplified, thereby reducing initial equipment cost and enhancing application flexibility. An intermediate-temperature fuel cell could possibly realize such an operation; however, the fuel-cell characteristics, especially the catalytic activity of the Pt/C anode, are not sufficient at present. In this study, we attempted to improve the anode activity by alloying Pt with other metals, followed by optimization of the alloy in terms of its atomic ratio and content. The resulting PtFe/C anode yielded higher power densities (37–42 mW cm−2) and energy densities (125–169 Wh kg−1) at 250 °C for fuels composed of cypress, tissue paper, and cotton, compared to those obtained using the Pt/C anode, despite its smaller Pt loading.
Case Report: Severe allergic reaction to Physiomesh® after laparoscopic ventral hernia repair
Authors: Mortensen Laura Quitzau , Bisgaard Thue , Hansen Tine Plato , Rosenberg Jacob
Published: May 2017

Due to a relative high rate of recurrence compared with other meshes for laparoscopic ventral hernia repair, Physiomesh® was recalled in 2016. This case report describes one of two reported cases of allergic reaction after insertion of Physiomesh®. The patient was a 50-year-old male who had a laparoscopic operation for ventral hernia with insertion of Physiomesh® as an intraperitoneal onlay procedure. Two months later, the patient was admitted with intense epigastric pain, and CT scan showed signs of ileus. Emergency surgery was performed revealing severe allergic signs in the abdomen and retroperitoneum. The mesh was removed. The postoperative course was complicated; the patient had multiple admissions with incomplete ileus, as well as recurrence of the ventral hernia. An open sublay hernia repair using a monofilament polyester mesh was subsequently performed with good effect. This case report illustrates a rare complication with mesh insertion. This adverse event adds to the risk of complications following implantation of mesh to reinforce a hernia repair. The allergic reaction was not suspected until during operation. Therefore, this report also illustrates the importance of surgeons’ clinical assessment and ability to take relevant action, which in this case consisted of mesh removal and retrieving tissue samples for histology.
The use of high-frequency ventilation during general anaesthesia: an update
Authors: Galmén Karolina , Harbut Piotr , Freedman Jacob , Jakobsson Jan G.
Published: May 2017

Various forms of high-frequency ventilation (HFV) have been described. HFV is broadly defined as artificial ventilation of the lungs with sub-deadspace tidal volumes delivered using supra-physiological frequencies. HFV has been used in anaesthesia and intensive care for special procedures and conditions since the 1960s. Clinical interest in the use and the technical evolution of HFV has developed over time. There is a renewed interest in HFV for avoiding parenchymal movement during stereotactic tumour ablation. The present paper aims to give an overview of the fundamental physiology, technical aspects, and clinical challenges of HFV in ablation procedures during general anaesthesia, where HFV is used to minimise the movements of the ablation target.
Recent advances in microbial fermentation for dairy and health
Authors: Hill Daragh , Sugrue Ivan , Arendt Elke , Hill Colin , Stanton Catherine , Ross R Paul
Published: May 2017

Microbial fermentation has been used historically for the preservation of foods, the health benefits of which have since come to light. Early dairy fermentations depended on the spontaneous activity of the indigenous microbiota of the milk. Modern fermentations rely on defined starter cultures with desirable characteristics to ensure consistency and commercial viability. The selection of defined starters depends on specific phenotypes that benefit the product by guaranteeing shelf life and ensuring safety, texture, and flavour. Lactic acid bacteria can produce a number of bioactive metabolites during fermentation, such as bacteriocins, biogenic amines, exopolysaccharides, and proteolytically released peptides, among others. Prebiotics are added to food fermentations to improve the performance of probiotics. It has also been found that prebiotics fermented in the gut can have benefits that go beyond helping probiotic growth. Studies are now looking at how the fermentation of prebiotics such as fructo-oligosaccharides can help in the prevention of diseases such as osteoporosis, obesity, and colorectal cancer. The potential to prevent or even treat disease through the fermentation of food is a medically and commercially attractive goal and is showing increasing promise. However, the stringent regulation of probiotics is beginning to detrimentally affect the field and limit their application.

Published: May 2017

High dimensional mass and flow cytometry (HDCyto) experiments have become a method of choice for high throughput interrogation and characterization of cell populations.Here, we present an R-based pipeline for differential analyses of HDCyto data, largely based on Bioconductor packages. We computationally define cell populations using FlowSOM clustering, and facilitate an optional but reproducible strategy for manual merging of algorithm-generated clusters. Our workflow offers different analysis paths, including association of cell type abundance with a phenotype or changes in signaling markers within specific subpopulations, or differential analyses of aggregated signals. Importantly, the differential analyses we show are based on regression frameworks where the HDCyto data is the response; thus, we are able to model arbitrary experimental designs, such as those with batch effects, paired designs and so on. In particular, we apply generalized linear mixed models to analyses of cell population abundance or cell-population-specific analyses of signaling markers, allowing overdispersion in cell count or aggregated signals across samples to be appropriately modeled. To support the formal statistical analyses, we encourage exploratory data analysis at every step, including quality control (e.g. multi-dimensional scaling plots), reporting of clustering results (dimensionality reduction, heatmaps with dendrograms) and differential analyses (e.g. plots of aggregated signals).
Nanoparticle-based drug delivery systems: What can they really do in vivo?
Authors: Wang Yi-Feng , Liu Lu , Xue Xue , Liang Xing-Jie
Published: May 2017

In the past few decades, there has been explosive growth in the construction of nanoparticle-based drug delivery systems (NDDSs), namely nanomedicines, owing to their unique properties compared with traditional drug formulations. However, because of a variety of challenges, few nanomedicines are on sale in the market or undergoing clinical trial at present. Thus, it is essential to look back and re-evaluate what these NDDSs can really do in vivo, why nanomedicines are regarded as potential candidates for next-generation drugs, and what the future of nanomedicine is. Here, we focus mainly on the properties of NDDSs that extend blood circulation, enhance penetration into deep tumor tissue, enable controllable release of the payload into the cytoplasm, and overcome multi-drug resistance. We further discuss how to promote the translation of nanomedicines into reality. This review may help to identify the functions of NDDSs that are really necessary before they are designed and to reduce the gap between basic research and clinical application.
RNA substrate length as an indicator of exosome interactions in vivo
Authors: Delan-Forino Clémentine , Schneider Claudia , Tollervey David
Published: May 2017

Background: The exosome complex plays key roles in RNA processing and degradation in Eukaryotes and Archaea. Outstanding structural studies identified multiple pathways for RNA substrates into the exosome in vitro, but identifying the pathway followed by individual RNA species in vivo remains challenging.

Methods: We attempted to address this question using RNase protection. In vivo RNA-protein crosslinking (CRAC) was applied to the exosome component Rrp44/Dis3, which has both endonuclease and exonuclease activity. During CRAC, the exosome was purified under native conditions and subjected to RNase digestion, prior to protein denaturation and cDNA cloning. The resulting high-throughput sequence reads were stratified by length of the cDNA sequence. This should reflect RNA fragment lengths, and therefore the RNA region that was protected by exosome binding. We anticipated major read lengths of ~30nt and ~10nt, reflecting the “central channel” and “direct access” routes to the Rrp44 exonuclease active site observed in vitro.

Results: Unexpectedly, no clear peak was observed at 30nt, whereas a broad peak was seen around 20nt. The expected ~10nt peak was seen, and showed strong elevation in strains lacking exonuclease activity. Unexpectedly, this peak was suppressed by point mutations in the Rrp44 endonuclease active site. This indicates that the short fragments are degraded by the exonuclease activity of Rrp44, but also suggests that at least some may be generated by endonuclease activity.

Conclusions: The absence of 30nt protected fragments may reflect obligatory binding of cofactors at the entrance to the exosome central channel in vivo. The presence of ~20nt fragments apparently indicates an access route not yet reported from in vitro studies. Confident mapping of 10nt reads is challenging, but they are clearly derived from a subset of exosome targets. In particular, pre-rRNA species, which are major exosome targets, are strongly disfavored for the generation of short reads.

Numerical modeling of cathode-directed streamers branching in strong electric fields
Authors: Белогловский  , Beloglovskiy Andrey , Федорова  , Fedorova A.
Published: May 2017

A research of conditions of the branching of positive streamer in air in a strong electric field by the use a three-dimensional numerical model is presented. This model is based on the assumption that the development of large electron avalanches in the strong field in front of the streamer head leads to branching. Tendency for branching has been observed, if the ratio of the diameters of the streamer heads to the distance between them is not greater than 0.55. If this ratio is more than 0,55, merger of originally formed streamer heads has been observed, and then only one streamer develops in the discharge gap.

Dispersion characteristics of surface magnetostatic wave with dissipation
Authors: Герус  , Gerus Sergey , Анненков  , Annenkov A.
Published: May 2017

It is shown that the dispersion characteristics of spin surface waves with dissipation unlike undamped waves have the wave number maximum value at which there is a reversal in the dispersion curve of wavenumber downward. This forms the upper branch of the dispersion curve with the inverse dispersion and high attenuation, which gives rise to ambiguous depending on the frequency of the wave vector. Lower primary dispersion branch corresponds to waves with a direct dispersion, attenuation is proportional to the small parameter of dissipation. However, near the wave number maximum value the attenuation coefficient of the waves sharply increases. Some angular and frequency limits of the of surface wave propagation are changed as well.
Energy characteristics of spin waves with noncollinear group and phase velocities in an infinite ferrite medium
Authors: Локк  , Lokk Edvin
Published: May 2017

Group velocity vector orientation ψ versus wave vector orientation  ´ is calculated for spin waves propagating in an infinite ferrite medium magnetized to saturation by uniform magnetic field H0. It is found that dependence ψ( ´) can have both extremum points and inflection points, in which derivative dψ/d is equal to zero. It means, that superdirected spin wave beams can arise in this medium. In the plane, containing vector H0, the angular width of such beams is not change during propagation and in the perpendicular plane the angular width of these beams, as in the isotropic media, is equal to λ/D.

Published: May 2017

Application of the method of collocations to solve the boundary integral equation for the density of the double layer at a piecewise constant approximation is incorrect, since in this case the boundary condition for the vector of the magnetic field is not executed. Proposed in this paper, a discrete-field model does not contain the collocation points, and the boundary conditions are an integral manner.

Electro-physical properties of polyvinylidenefluoride copolymers (F-2M, F-42, SKF-32brands) were investigated. Such materials can be used as matrix media for producing the composites with multiferroicity properties and controlled dispersion. By using high-voltage polarization method it is shown that polymers F-2M, F-42 have expressed ferroelectric properties and Synthetic FPM SKF-32 is a highly polar dielectric. It is endorsed by studying structural properties with methods of differential scanning calorimetry and X-ray diffractometry, which show the presence of a large degree of crystallinity in the test based on samples F-2M and F-42.

Currently on the way are R&D works targeted to expand operational frequencies of microwave devices, including frequency selective ones. The expansion occurs both at low and at high end of the frequency range. Due to the microwave communication systems trend of increasing transmitted data flow rate and volume, as well as for precise object resolution by the vision systems, one needs to shift microwave device operational frequencies to the mm-wave range.
Operational frequencies of mm-wave range microwave devices are defined by crystallographic magnetic anisotropy field and magnetic activity of the ferrite material (4πМS/ΔH), related with saturation magnetization and ferromagnetic resonance (FMR) line width. For creation of mm-wave range frequency selective devices are needed the ferrite resonators made of materials with high crystallographic magnetic anisotropy field values, as well as high saturation magnetization and narrow FMR line width. R&D works undertaken in the institute show that such materials can be created on the basis of ferrites with hexagonal structure. As a starting point for the development of the material was taken barium hexaferrite with M-type structure
(BaFe12O19). Single crystals with composition BaFe12-xAlxO19 and BaFe12-xScxO19 were received from a solution in melt. By this way one may create materials with anisotropy field values from 5 to 50 kÖe, saturation magnetization from 3900 to 4700 Gauss, narrow FMR line width, and Curie temperature from 370° to 445° С.
The dependencies of crystallographic magnetic anisotropy field and saturation magnetization vs diamagnetic dilution and temperature are investigated, as well as FMR line width vs temperature, density and orientation of the growing grains.

The method of radiation-thermal sintering (RTS) in the fast electron beam by accelerator ILU-6 obtained samples of barium hexaferrite BaFe12O19 and substituted barium hexaferrite BaFe9,5Al2,5O19 (with additions of Ni, Ti, Mn). The research synthesized samples was carried out by X-ray structural analysis and X-ray phase analysis. It is found that both compounds besides the main phase samples (BaFe12O19 and BaFe9,5Al2,5O19, respectively), is also present phase BaFe2O4. With increasing sintering temperature from 1100°C to 1300°C phase barium monoferrite intensity decreases or disappears completely, and at a temperature of 1400°C this phase is fixed again (its intensity continues to increase). The possibility of practical use of the results.
