Abstract
OBJECTIVE To investigate whether hemivertebra subtype as determined via CT was associated with breed and Cobb angle (a measure of the degree of spinal curvature) in apparently neurologically normal French Bulldogs, English Bulldogs, and Pugs.
ANIMALS Client-owned French Bulldogs (n = 58), English Bulldogs (30), and Pugs (12) with thoracic hemivertebrae that underwent CT for reasons unrelated to spinal disease.
PROCEDURES CT scans of each dog were evaluated, and hemivertebrae were categorized by subtype (ventral aplasia, ventral hypoplasia, lateral aplasia, lateral hypoplasia, ventrolateral aplasia, ventrolateral hypoplasia, ventral and median aplasia, ventral and median hypoplasia, and symmetric hypoplasia). The Cobb angle was measured, and kyphosis was defined as a Cobb angle > 10°. Results were compared among breeds.
RESULTS 243 hemivertebrae were identified in the French Bulldog group, 100 in the English Bulldog group, and 19 in the Pug group. Breed was significantly associated with hemivertebra subtype. Pugs were more likely than French and English Bulldogs to have ventral hypoplasia and less likely to have ventral and median hypoplasia. English Bulldogs were more likely than French Bulldogs to have ventral and median hypoplasia. Compared with other hemivertebra subtypes, ventral hypoplasia was associated with a greater Cobb angle and a higher likelihood of kyphosis. Pugs were more likely than the other 2 breeds to have kyphosis.
CONCLUSIONS AND CLINICAL RELEVANCE Pugs had a different spectrum of hemivertebra subtypes than French and English Bulldogs in this study. Additional research is necessary to evaluate the clinical relevance of this finding.
Path Following Control of Fully Actuated Autonomous Underwater Vehicle Based on LADRC

Published: January 2019

Abstract
This paper presents an active disturbances rejecter controller (ADRC) for position and path following control of a fully actuated autonomous underwater vehicle (AUV). The unmodeled, undesirable dynamics and disturbances reduce the performances of classical controllers and complicate the design of appropriate and efficient controllers. In the proposed approach, the different modeling complexities; such as uncertain parameters, non-linearities, and external disturbances are considered all as a part of disturbance which is estimated in real-time by the extended state observer ESO, and effectively compensated from the control law. The ESO is also able to estimate the position and velocity of the system in real-time, in case where the full state measurement of the AUV is not possible during experiments. Computer simulations demonstrate the high ability of the AUV tracking control based on ADRC, to follow the desired trajectory in the horizontal plane and space with high precision, and showed high robustness and efficiency in rejecting the external and internal disturbances caused by significant changes in parameters of the system, and the added position disturbances.

Abstract

Background
The aim of the study was to evaluate and compare four different external beam radiotherapy techniques of accelerated partial breast irradiation (APBI) considering target coverage, dose to organs at risk and overall plan quality. The investigated techniques were three dimensional conformal radiotherapy (3D-CRT), “step and shoot” (SS) and “sliding window” (SW) intensity-modulated radiotherapy (IMRT), intensity-modulated arc therapy (RA).

Patients and methods
CT scans of 40 APBI patients were selected for the study. The planning objectives were set up according to the international recommendations. Homogeneity, conformity and plan quality indices were calculated from volumetric and dosimetric parameters of target volumes and organs at risk. The total monitor units and feasibility were also investigated.

Results
There were no significant differences in the coverage of the target volume between the techniques. The homogeneity indices of 3D-CRT, SS, SW and RA plans were 0.068, 0.074, 0.058 and 0.081, respectively. The conformation numbers were 0.60, 0.80, 0.82 and 0.89, respectively. The V50% values of the ipsilateral breast for 3D-CRT, SS, SW and RA were 47.5%, 40.2%, 39.9% and 31.6%, respectively. The average V10% and V40% values of ipsilateral lung were 13.1%, 28.1%, 28%, 36% and 2.6%, 1.9%, 1.9%, 3%, respectively. The 3D-CRT technique provided the best heart protection, especially in the low dose region. All contralateral organs received low doses. The SW technique achieved the best plan quality index (PQI).

Conclusions
Good target volume coverage and tolerable dose to the organs at risk are achievable with all four techniques. Taking into account all aspects, we recommend the SW IMRT technique for APBI.

Abstract

Background
Astrocytes maintain central nerve system homeostasis and are relatively resistant to cell death. Dysfunction of cell death mechanisms may underlie glioblastoma genesis and resistance to cancer therapy; therefore more detailed understanding of astrocytic death modalities is needed in order to design effective therapy. The purpose of this study was to determine the effect of VAS2870, a pan-NADPH oxidase inhibitor, on staurosporine-induced cell death in astrocytes.

Materials and methods
Cultured rat astrocytes were treated with staurosporine as activator of cell death. Cell viability, production of reactive oxygen species (ROS), and mitochondrial potential were examined using flow cytometric analysis, while chemiluminescence analysis was performed to assess caspase 3/7 activity and cellular ATP.

Results
We show here for the first time, that VAS2870 is able to prevent staurosporine-induced cell death. Staurosporine exerts its toxic effect through increased generation of ROS, while VAS2870 reduces the level of ROS. Further, VAS2870 partially restores mitochondrial inner membrane potential and level of ATP in staurosporine treated cells.

Conclusions
Staurosporine induces cell death in cultured rat astrocytes through oxidative stress. Generation of ROS, mitochondrial membrane potential and energy level are sensitive to VAS2870, which suggests NADPH oxidases as an important effector of cell death. Consequently, NADPH oxidases activation pathway could be an important target to modulate astrocytic death.

Abstract
Knee osteoarthritis (gonarthrosis) is the most prevalent knee pathology encountered nowadays in the third age population, leading to severe disability and reduced life quality. Secondary gonarthrosis may be caused by a traumatic event, which subjects the knee joint to a transitory highly increased mechanical stress, initiating a rapidly progressive degrading process of the articular cartilage and subjacent bone tissue. TKA is intended to replace all the intra-articular components with artificial parts, in order to relieve pain, compensate for ligament instability, correct deformities, and restore proper joint functionality. Semi-constrained, non-hinged implants are usually used for revision TKA, in knees that already had a primary TKA but sustained complications. Nevertheless, here we reported the case of a 66-year-old female patient diagnosed with posttraumatic gonarthrosis who underwent TKA with a revision total stabilizer implant as primary treatment due to severe joint instability and high grade valgus deviation. The outcome of the surgical procedure was positive, with significant pain relief and increased knee stability. The valgus angle was reduced from 37° to 4° and the KSS score increased from 3 to 87 points. Therefore, revision semi-constrained prosthesis may be used as a primary implant with promising result in severe cases.

Evaluation of xanthine oxidase inhibitory activity and polyphenolic content of sappan extractABSTRACTHyperuricemia is a disease that is characterized by a high uric acid level, in which the number of patients tends to increase every year. This research was intended to evaluate the xanthine oxidase (XO) inhibitory activity and determinate the total polyphenol content of heartwood sappan (Caesalpinia sappan L.) extract. The extract was prepared by macerating the dry powder wood using 70% ethanol at room temperature. The quality of ethanolic extract obtained was evaluated based on BPOM guideline. XO inhibitory power was determined by measuring uric acid produced in the xanthine/XO system in vitro. The polyphenol content of the extract was measured using Folin-Ciocalteu reagent spectrophotometrically. The results showed that the quality of sappan semisolid extract fulfilled the required standard. Sappan extract inhibited XO activity by 98% relative to the positive control, allopurinol, at the final extract concentration of 100 µg/mL. The total polyphenol content was 26% of the crude extract. It could be concluded that sappan ethanolic extract has the potential to be developed as an ingredient for hyperuricemia treatment.Keywords: hyperuricemia, sappan, total polyphenol, xanthine, xanthine oxidase ABSTRAKHiperurisemia adalah penyakit yang dicirikan dengan kadar asam urat tinggi dimana prevalensi penderita cenderung meningkat.

The Effect of Culture Container and Carbon Source Concentration on In Vitro Shoot Propagation of Atlantic PotatoABSTRACTPotato is a food commodity that has the potential to support food diversification in Indonesia. There is an increasing demand for Atlantic potatoes as the raw material for processed potato products. The demand, which has not been met by the increased production, has been the cause of the ongoing potato import activities in Indonesia. The limitation of producing quality Atlantic potato seeds economically is one of the obstacles to increasing the production of Atlantic potatoes in Indonesia. The aim of this research was to study the effect of various table sugar concentrations as the carbon source and the type of the culture containers used for Atlantic potato shoot multiplication in vitro. The propagation was carried out in bioreactors and culture bottles with MS liquid medium + coconut water at a concentration of 150 mL/L medium, and 3 concentration levels of table sugar, namely 0; 7.5; and 15 g/L medium. The use of bioreactor significantly increased the height of the Atlantic potato plantlets. The use of bioreactor combined with table sugar addition decreased hyperhydricity level. The highest number of shoots, leaves, and roots were found at the table sugar concentration of 15 g/L medium in both containers.Keywords: bioreactor, micropropagation, shoot culture, Solanum tuberosum, sucrose ABSTRAKKentang merupakan komoditas pangan yang berpotensi mendukung program diversifikasi pangan di Indonesia.

Impact of Slicing and Moulding Techniques on the Floatability of the Fish Feed Fermented by Rhizopus sp.ABSTRACTThe use of Rhizopus sp. mycelium as biocoating, biostabilizing, and biofloating agent in the production of floating fish feed through solid fermentation had already been studied as a much simpler alternative to mechanical extrusion. The fermented fish feed, however, had poor floatability in aerated water, probably due to structural damage during the size reduction process of the feed. Thus, this study used alternative size-reducing methods, namely slicing and moulding, to improve the floatability of the fermented feed. Other physical characteristics were also measured and compared to those of commercial sinking and floating fish feeds. Results showed that both the moulded and the sliced fermented-feeds had lower density as well as higher water stability, absorption capacity, floatability, and durability compared to those of the commercial sinking feed used as the fermentation substrate. The hydrophobicity of all the feeds tested were similar, however. The floatability of the fermented feeds obtained in this study was much higher than those of the previous studies. Keywords: floatability, floating feed, sinking feed, water absorption, water stabilityABSTRAKPenggunaan miselium Rhizopus sp. sebagai pelapis permukaan, penstabil, dan pengapung hayati dalam pembuatan pakan ikan apung melalui fermentasi padat telah diteliti sebagai alternatif yang jauh lebih sederhana dibandingkan dengan metode ekstrusi mesin. Namun, pakan ikan fermentasi ini memiliki daya apung yang buruk dalam air bergelembung udara, yang mungkin disebabkan kerusakan struktural selama proses pengecilan ukuran pakan. Karenanya, penelitian ini menggunakan metode lain untuk mengecilkan ukuran, yakni pencetakan dan pengirisan, dalam rangka meningkatkan daya apung pakan yang difermentasi. Karakteristik fisik lainnya juga diukur dan dibandingkan dengan pakan ikan tenggelam dan terapung komersial. Hasil menunjukkan bahwa proses fermentasi serta metode pengecilan dimensi yang digunakan menghasilkan pakan yang memiliki massa jenis lebih rendah, serta stabilitas air, daya serap air, daya apung, serta ketahanan benturan lebih tinggi dibandingkan dengan pakan tenggelam komersial yang digunakan sebagai substrat fermentasi. Namun, nilai hidrofobisitas semua pakan yang diuji adalah sama. Daya apung pakan fermentasi dalam penelitian ini jauh lebih tinggi daripada penelitian sebelumnya.Kata Kunci: daya apung, daya serap air, stabilitas dalam air, pakan apung, pakan tenggelam
