The temporomandibular joint (TMJ) is one of the most underdiagnosed and undertreated conditions of juvenile idiopathic arthritis (JIA) because its involvement is often asymptomatic and the joint is ...difficult to examine.
The aim of this study was to investigate clinical as well as magnetic resonance imaging findings of temporomandibular joint inflammation among juvenile idiopathic arthritis patients and to detect the correlation between them, moreover with different disease parameters.
Forty patients with JIA and 10 apparently healthy control subjects underwent clinical and post contrast magnetic resonance imaging (MRI) examinations for TMJs. MRI findings were scored. Clinical and laboratory disease parameters were recorded.
The clinical symptoms and signs of TMJ arthritis were detected in 35% and 62.5% of JIA cases, respectively. While TMJ disease was observed in 80% of patients using contrast enhanced MRI. The mean total MRI score was significantly higher in patients with active disease compared to those without activity. Patients with systemic and polyarticular JIA showed significant increase in the mean of synovial enhancement, effusion and total MRI scores compared to those with the oligoarticular type. MRI abnormalities revealed significant association with clinical signs of TMJ examination but not with symptoms. Synovial enhancement score showed significant positive correlation with disease activity score and C-reactive protein as a marker of inflammation. A significant positive correlation was found between total MRI score and disease activity, functional and pain scores in patients with JIA.
TMJ arthritis is common among patients with JIA, therefore; examination of the TMJ is mandatory during the follow up of patients. Clinical signs of TMJ arthritis can be used as filter for MRI examination TMJ is an important joint which may be considered during categorizing JIA patients in different subtypes.
With the rapid increase in digital technologies, most fields of study include recognition of human activity and intention recognition, which are essential in smart environments. In this study, we ...equipped the activity recognition system with the ability to recognize intentions by affecting the pace of movement of individuals in the representation of images. Using this technology in various environments such as elevators and automatic doors will lead to identifying those who intend to pass the automatic door from those who are passing by. This system, if applied in elevators and automatic doors, will save energy and increase efficiency. For this study, data preparation is applied to combine the spatial and temporal features with the help of digital image processing principles. Nevertheless, unlike previous studies, only one AlexNet neural network is used instead of two-stream convolutional neural networks. Our embedded system was implemented with an accuracy of 98.78% on our intention recognition dataset. We also examined our data representation approach on other datasets, including HMDB-51, KTH, and Weizmann, and obtained accuracy of 78.48%, 97.95%, and 100%, respectively. The image recognition and neural network models were simulated and implemented using Xilinx simulators for the Xilinx ZCU102 board. The operating frequency of this embedded system is 333 MHz, and it works in real-time with 120 frames per second (fps).
Bakterije mliječne kiseline (BMK) igraju vrlo važnu ulogu kao prirodni biokonzervansi u hrani. Prema tome, istražen je inhibicijski učinak Lactobacillus rhamnosus (L. rhamnosus) prema 4 vrste ...Yarrowia kvasaca i plijesni: Penicillium expansum (P. expansum), Saccharomyces cerevisiae (S. cerevisiae), Aspergillus niger (A. niger), Kluyveromyces lactis (K. lactis). Zatim je P. expansum odabran kao najvažniji kontaminant iz roda plijesni u jogurtu kako bi se istražila upotreba L. rhamnosus za selektivno smanjenje kvarenja jogurta uzrokovanog navedenim sojem plijesni. Također je određivan učinak ove biozaštitne kulture na broj starter bakterija i neke karakteristike jogurta. L. rhamnosus (106 cfu/mL) inokuliran je u mlijeko zajedno s jogurtnom starter kulturom pri čemu su proizvedena četiri uzorka T0 (L. rhamnosus = 0, P. expansum = 0), T1 (L. rhamnosus = 106 cfu/mL, P. expansum = 0), T2 (L. rhamnosus = 0, P. expansum = 105 cfu). /mL); T3 (L. rhamnosus = 106 cfu/mL, P. expansum = 105 cfu/mL). U svim uzorcima je određivana pH vrijednost, viskoznost, sinereza, mikrobiološki parametri tj. preživljavanje Streptococcus thermophilus, Lactobacillus bulgaricus i P. expansum, te ukupna prihvatljivost. L. rhamnosus je inhibiraio preživljavanje P. expansum (p<0,05), ali ga nije mogao u potpunosti kontrolirati. L. rhamnosus je u uzorku T3 pokazao jak inhibicijski učinak od prvog dana do kraja skladištenja. Nadalje, tijekom skladištenja preživljavanje sojeva jogurtne starter kulture u uzorcima probiotičkog jogurta bilo je veće od kontrolnog (p<0,05). T3 je imao niži pH, viskoznost i ukupni rezultat prihvatljivosti u usporedbi s kontrolnim uzorkom, a sinereza mu je bila viša (p<0,05). Općenito, dodavanje 106 cfu/mL L. rhamnosus nije u potpunosti inhibiralo rast soja P. expansum (105 CFU/mL) tijekom perioda skladištenja jogurta.
