Abstract:
Background & Aim: Optimization of the differentiation medium through using autologous factors such as PRP is of great consideration, but due to the complex, variable and undefined composition of PRP on one hand and lack of control over the absolute regulatory mechanisms in in vitro conditions or disrupted and different mechanisms in diseased tissue microenvironments in in vivo conditions on the other hand, it is complicated and rather unpredictable to get the desired effects of PRP making it inevitable to monitor the possible pathologic or undesired differentiation pathways and therapeutic effects of PRP. Therefore, in this study the probable potential of PRP on inducing calcification, inflammation and angiogenesis in chondrogenically differentiated cells was investigated.
Methods: The expressions of chondrogenic, inflammatory, osteogenic and angiogenic markers from TGF or PRP-treated cells during chondrogenic differentiation of human adipose-derived stem cells (ADSCs) was evaluated. Expressions of Collagen II (Col II), Aggrecan, Sox9 and Runx2 were quantified using q-RT PCR. Expression of Col II and X was investigated by immunocytochemistry as well. Glycosaminoglycans (GAGs) production was also determined by GAG assay. Possible angiogenic/inflammatory potential was determined by quantitatively measuring the secreted VEGF, TNF and phosphorylated VEGFR2 via ELISA. In addition, the calcification of the construct was monitored by measuring ALP activity and calcium deposition.
Results: Our data showed that PRP positively induced chondrogenesis; meanwhile the secretion of angiogenic and inflammatory markers was decreased. VEGFR2 phosphorylation and ALP activity had a decreasing trend, ut tissue mineralization was enhanced upon treating with PRP.
Conclusions: Although reduction in inflammatory/angiogenic potential of the chondrogenically differentiated constructs highlights the superior effectiveness of PRP in comparison to TGF for chondrogenic differentiation, yet further improvement of the PRP-based chondrogenic differentiation media is required to inhibit the production of angiogenic/inflammatory markers, calcification and the release of synthesized GAG out of the construct.

Title: Effect of green manure crops treatments on the soil conditions and corn yield production
Biography:
Abstract:
This study was conducted to find optimum mixed sowing ratio of green manure crops to improve the chemical soil condition as well as to increase the crop yield potential which will foster the utilization of green manure crops in the upland field in view of environment friendly agriculture. According to the study, the mixed ratio, 50:50, of hairy vetch and green barley showed highest nitrogen production yield, 17. 2kg per 10a, in the soil due to the relatively higher organic nitrogen supply from the hairy vetch plant as well as nitrogen fixation from the air rather than other mixed ratio. Otherwise, other soil chemical conditions, such as pH, EC, Av. P2O3 and exchangeable cations, showed different results depending on the mixed sowing ratio of green manure crops. In case of pH, the mixed ratio, 100:0, treatment showed to increase to 7.0 from 6.0 of control (chemical fertilizer treatment). Available P2O3 amount showed highest at the mixed ratio, 100:0, treatment as 453 mg/kg. We also conducted the experiment to compare the effect of the mixed sowing treatment of green manure crops on the production of corn cultivated as a succeeding plant of green manure crops. The mixed ratio, 50:50, of hairy vetch and green barley treatment showed highest yield potential of corn as 153 kg per 10a in seed weight which is due to the relatively higher organic nitrogen supply from the hairy vetch plant as well as nitrogen fixation from the air rather than other mixed ratio. In the mixed sowing treatment of hairy vetch 100 and barley 0 ratio, the corn production showed 148 kg per 10a which is 5 kg lower than that of hairy vetch 50 and barley 50 ratio, but showed statistically no difference between those two treatment Therefore, we found that green manure crops, such as hairy vetch, green barley and rye were very effective crops to improve the soil fertility and gave the positive effect to the crop cultivation and, in turn, increased the yield potential.

Title: An FPGAâ€based chaos synchronisation classifier for estimation of peripheral vascular occlusion using photoplethysmography
Biography:
Abstract:
This study proposes a method for the estimation of peripheral vascular occlusion (PVO) in diabetic foot using a sprott chaos synchronisation (SCS) classifier with the wolf pack search (WPS) algorithm. The longterm presence of elevated blood sugar levels commonly results in peripheral neuropathy, peripheral vascular disease, nephropathy, and retinopathy in patients with Type 2 diabetes mellitus. Patients with PVO disease have decreased walking capability and life quality in diabetes mellitus and poor peripheral circulation of PVO causes morbidity like infection and amputation of the legs or feet of diabetics. This progressively vascular occlusion is often ignored by the patients and primary care physicians in early stage. Therefore, a reliable method of diagnostic assistance is crucial for early diagnosis and monitoring of PVO and prevention of amputation. Photoplethysmography (PPG) is a non-invasive technique for detecting blood volume changes in peripheral vascular bed. Literature indicates that the pulse transit time increases and waveform shape changes increase in PPG of the vascular occlusion. PPG pulses of feet gradually become asynchronous due to the different speed of deteriorating patency and collateral circulation in the peripheral arteries. We utilized synchronizing chaotification to compare the bilateral similarity and asymmetry of PPG signals, and applied SCS to estimate three degrees of PVO. Among 30 subjects tested, this classification technique could recognize various butterfly motion patterns representing severities successfully including normal condition, lower-degree disease, and higher-degree disease. The proposed method has potential for providing diagnostic assistance for PVO of diabetics and other high-risk populations, with efficiency and higher accuracy.
