4. Regulatory Assessment of Premarket Approval of Medical Devices in US and EU
, Divya Teja Bandla
The demand for medical devices globally has raised the attention of government regulatory bodies to ensure the safety and effectiveness of these products. Developed markets, such as the United States and European Union, have set up well-established regulatory systems for medical devices, which have consistently been amended to accommodate the changing requirements of safety and the trend of globalization. The way in which devices are regulated in the European Union is very different from that of United States, especially in terms of the clinical data required for premarket approval. This has introduced significant differences in time-to-market approval for both United States and European Union, particularly in the case of high-risk Class III and Class IIb implantable devices. Systems for approving new medical devices must provide pathways to market important innovations besides ensuring that patients are adequately protected. To achieve these goals, the United States and the European Union use a combination of premarket testing and postmarket vigilance but with some marked contrasts in their approaches. Features of both environments require reform, as well as continuing research to assess policy changes which will benefit device manufacturers to develop devices which can be marketed both in US and EU simultaneously.

Nattokinase or subtilisin NAT (EC 22.214.171.124) is one of the most remarkable enzymes produced by Bacillus subtilis
sp. Natto, which posses direct fibrinolytic activity. The aim of this study is in silico
analysis of Nattokinase structure and function. The three-dimensional structure of serine protease Nattokinase from Bacillus subtilis sp. natto
was determined using homology modeling performed by Geno3D2 Web Server and refined by ModRefiner. The obtained models were validated via programs such as RAMPAGE, ERRAT, 3D Match and verify 3D for consistency; moreover, functional analysis performed by PFP from Kihara Bioinformatics laboratory. RAMPAGE analysis showed that 96.7% of the residues are located in the favored region, 3.0% in allowed region and 0.4% in outlier region of the Ramachandran plot. The verify 3D value of 0.73 indicates that the environmental sketch of the model is fine. SOPMA and PSIPRED were exploited for computation of the secondary structural properties of serine protease Nattokinase. Active site determination via AADS suggested that this enzyme can be applied as a potent enzyme for cardiovascular therapy. However, these results should be more confirmed by wet lab researches for designing the more active enzyme for better functions on its fibrinolysis activity.

Hapsari R N, Asmaningsih N, Padolo E, Yulistiani
Background The use of high dose and long-term prednisone as glucocorticoid in steroid-sensitive nephrotic syndrome patients can cause the suppressive effect on endogenous steroid production, namely HPA axis suppression which is characterized by the decrease of ACTH levels. This can decrease cortisol levels so can affect metabolism process, immune response, and brain function. Objective To analyze ACTH levels in the induction and alternating phase, and to relate with the patient’s condition both clinical and laboratory data. Methods ACTH levels were measured before and after induction phase and four weeks after alternating phase at 08.00-09.30 a.m. Results 15 patients consisted of 9 boys and 6 girls showed there were no significant differences between ACTH levels in each phase. ACTH levels were increased 23.6% from 22.2 ± 13.1 pg/mL to 27.4 ± 23.0 pg/mL during the induction phase (p>0.05) and alternating phase also showed that ACTH levels were increased 1.7% from 27.4 ± 23.0 pg/mL to 27.9 ± 22.2 pg/mL (p>0.05). The clinical manifestation of HPA axis suppression such as hypoglycemia, hypotension, weight loss, appetite loss, and acute dehydration were not found in the patients. Weakness, fatigue, nausea, vomiting, and abdominal pain were found only 7% after the induction phase. Conclusion HPA axis suppression did not occur after the high dose and long-term prednisone therapy in the induction and alternating phase which showed ACTH levels average in normal range. It was also supported by the absence of clinical and laboratory data that showed signs of HPA axis suppression.

Due to the ever increasing pressure on cultivated land the importance of intercropping in farming practices has been recognized. This study was performed to evaluate the effect of intercropping ryegrass (Lolium multiflorum
with fenugreek (Trigonella foenum-graecum
L.). For this purpose, a field experiment was arranged based on randomized complete block design with three replications at the experimental farm of faculty of agriculture Cairo University at Giza, Egypt during two seasons of 2015 and 2016. The experimental treatments were planting patterns (sole crop of rye or fenugreek and intercropping ratios of 1 rye: 1 fenugreek, 2 rye: 1 fenugreek and 1 rye: 2 fenugreek). Results showed that intercropping system had positive effects on ryegrass yield. Moreover, the planting ratio of 2 rye: 1 fenugreek gave the maximum values of ryegrass fresh and dry yield in both cuts compared with the other treatments of the sole crop and the other intercropping ratios in the first and second season, respectively. The application of sole crop had the highest fenugreek fresh and dry yield and seed yield too in both seasons compared with other treatments, respectively. While, the maximum significant levels of chemical contents (oil and protein percentage) of fenugreek seeds were found with the sole fenugreek crop and the intercropping ratio of 1 rye: 2fenugreek, respectively as compared with the other treatments but the differences between the fenugreek sole crop and the other studied intercropping system in the percentage of trigoniline were insignificant in both seasons, respectively. The maximum significant values of competitive ratio (CR) and aggresivity (A) for rye grass crop was found in the pattern ratio of 1rye: 2 fenugreek in both seasons, respectively. While the same situation was recorded with fenugreek crop in the pattern ratio of 2 rye: 1 fenugreek in both seasons, respectively. The highest total land equivalent ratio (LER) (3.08 and 2.98 for the first and second seasons, respectively) was obtained by sowing the crops in the intercrop ratio of 2 rye: 1 fenugreek and the lowest total LER (2.57and 2.48 in both seasons, respectively) was obtained by using the intercrop ratio of 1 rye: 1 fenugreek. In addition, all intercropping treatments in both seasons, respectively gave values of LER for rye grass or fenugreek or both of them more than one. These findings suggest that intercropping of fenugreek and ryegrass increased the total productivity per unit area.

Preeclampsia/eclampsia (PEE) was the main cause of death in pregnancy. However, until now, this disease has no adequate medical prevention for lack of its basic molecular pathomechanism. In recent years, there are growing number of study has concern trophoblast apoptosis as important trigger. Thropoblast apoptosis has been shown in many report lead to trophoblast failure to invade into endometrial tissue. Invasion failure of trophoblast was characterized with high expression of IL-17 in its tissue. Spirulina arthrospira
plant or also called blue-green algae has been consumed since by the Aztec tribe. Several studies have proven that this plant have the immunomodulation properties stimulate various immune functions such as production of cytokines, chemokines and other anti-inflammatory mediators. Its active bioactive Phycocyanin (PC) has been shown have an effect as anti-inflammatory and antioxidant. Previous study has been shown that this substance has beneficial effect in preeclampsia inhibition in rat models via its inflammatory reducing effect However, there are lack of information concerning its role in trophoblast IL-17. Hence, this study is conduct to reveal its role in IL-17 expression in trophoblast in preeclampsia. Methods. This research used animal models with PE/E pregnant rat. PE/E induced by IL-6 intravein at dose 5 ng/100 g/day body weight. Animals divided in 6 groups of treatment with two groups control and four groups of PC treatment in different dose. After decapitated, uterus tissue processed to view its IL-17 expression using immunofluoresnce Result. This study has proven IL-17 reducing effect of PC in preeclampsia model of pregnant rats induced by IL -6. PC has reducing IL-17 expression significantly in trophoblast tissue of pregnant rats models induced by IL-6 at dose of 40 ng/100 kg weight. Conclusion. This study confirm that PC has a protective effect on pregnant rats preeclampsia through its inhibiton of trophoblast IL-17.
