Published: December 2019

<p>Microfinance is one of the key aspects that help the development of MSME, and it also applies globally. In many previous studies, there are no coherence about the impact of microfinance towards the development of MSME. We investigate the impact of microfinance to the development of MSME in Indonesia. Panel regression is the method that is utilized in this present study because the current data is in panel form which came from 32 provinces in Indonesia with the range of 2012-2014. Results indicated that there are two variables which are the number of microloans, HDI that significantly influence the development of MSME, microloans and HDI are negatively affected. The conclusion reflected the public views of Indonesian regarding entrepreneurship &amp; MSME development. Entrepreneurship is viewed poorly by the public, society values working in cooperations are more valuable.The results of the research also indicated boundaries such as regulations, and views that obstructed the development of MSME in Indonesia. </p>

Authors: Et al. Ali 
Published: December 2019

Peroxidase is a class of oxidation-reduction reaction enzyme that is useful for accelerating many oxidative reactions that protect cells from the harmful effects of free radicals. Peroxidase is found in many common sources like plants, animals and microbes and have extensive uses in numerous industries such as industrial, medical and food processing. In this study, P. aeruginosa was harvested to utilize and study its peroxidases. P. aeruginosa was isolated from a burn patient, and the isolate was verified as P. aeruginosa using staining techniques, biochemical assay, morphological, and a sensitivity test. The gram stain and biochemical test result show rod pink gram-negative bacteria, and ensure that the isolate was that of P. aeruginosa. Optimization for bacterial growth were done by used more than pH (5,7,9) and temperatures (32,35,37°C), and it was found that the best growth conditions were at pH 5.5, producing (4.5x108cells), and a temperature of 37°C, with (5.25x108cells) being produced. Intracellular enzymes were extracted by ultra-sonication that used frequencies of ultrasound 30 kHz for 20 min in 4 °C, and was centrifuged at 13000×g for 5min. The supernatant was then re-used as a crude enzymatic extract and the cell pellet was discarded. Purification of peroxidase was accomplished by using salt precipitation, dialysis, gel filtrations and ion exchange chromatographic techniques. The result shows that gel filtration has optimal specific activity and purification fold at (61 U/ml), purification fold 6 times and then the improvement enzyme was applied as H2O2 scavenging activity antioxidant by used three concentration of enzyme (10,40,60 µg/ml), and show higher scavenging activity at 60 µg/ml, which reached to 45% scavenging activity. The enzyme was also used as anticancer agent, which was verified by using three concentration of enzyme (10,15,20 µg/ml) which show a significant kill for Mcf-7cells at (15µg/ml), with cytotoxicity activity reaching (45%).

Authors: Et al. Nabeel 
Published: December 2019

The thermodynamic constanting of “crude and partially purified” Paraxonase(PON) was evaluated in the sera of “healthy and ectopic” pregnant women in order to characterize the reaction of PON with diethyl para-nitro phenyl phosphate as substrate.This study was performed on (17) women with ectopic pregnancy (EP) whose age between (25-55) years and (25) normal pregnant women with a mean age of (25 -55) years as a control group . Samples were collected from the Medical City, AL-Yarmook and Fatema AL-Zahraa hospitals during the period from Sep.2011 to April 2012.The study included the evaluation of “paraxonase activity, specific activity and total protein” in the (crude and partially purified) sera of EP patients & healthy subjects. The results demonstrated that there was significant decline (p≤0.05) in the activity and specific activity of PON and significant increase (p≤0.05) in the protein concentration. The study also included the evaluation of the energetic parameters: the Gibb`s free energy (ΔG) enthalpy change (ΔH), heat of activation,(ΔH*), entropy change(ΔS), temperature coefficient (Q10) and activation energy (Ea) with respect to human PON. The results indicated that there was a dramatic increase in each of the thermodynamic parameters (ΔG,Ea,ΔH,ΔS,ΔH*,Pz,Q10) for purified PON compared with enzyme in crude sera. The results indicated also that there was a dramatic increase in each of the thermodynamic parameters (ΔG, Ea, ΔH,ΔS,ΔH*,Pz,Q10) for purified PON compared with enzyme in crude sera which indicated that the purified PON suffered from the lack metals or substances that help enzyme to over come energy barrier, at the same time the purified PON(the freedom enzyme) had the greatest chance to collide and create of the favorable orientation with substrate.

Abstract
Background Insomnia is a common sleep disorder for adults with depression with major impact on the quality of life. Previous trials suggest that music listening may be helpful in the treatment of sleep disturbances in healthy populations including students and elderly. In addition, small studies with clinical populations of traumatized refugees, adults with chronic insomnia and adults with depression insomnia add to the evidence base. However, the impact of music listening in the treatment of depression related insomnia is not well documented. Objective To examine the efficacy of music listening on sleep quality, symptoms of depression and quality of life in adults with depression related insomnia. Method A single center randomized controlled trial (RCT) in a two arm parallel group design is conducted and reported according to the Consort guidelines. The trial consists of an experimental group and a standard care control group. Both groups receive standard treatment for depression following Danish guidelines in an outpatient unit in psychiatry. The experimental group listen to music minimum 30 minutes at bedtime in four weeks. Discussion This study will provide information on the efficacy of music intervention as a non-pharmacological intervention in the treatment of depression related insomnia. This study will provide novel knowledge concerning music medicine as an evidence based treatment of depression in psychiatry. Trial Registration: Clinicaltrials.gov. ID NCT03676491, registered on 19th of September 2018. Keywords: Music, insomnia, depression, sleep

Published: December 2019

Abstract
Background Retinitis pigmentosa (RP) is the most common cause of blindness in retinal disease. Long-lasting ocular administration is an effective therapy to delay the progression of RP. And hydrogel sustained release system may be an available and stable drug carrier in the treatment of RP.Method Hydrogel sustained release system was constructed as a drug carrier of recombinant human erythropoietin (rhEPO). We administered retinal degenerative (rd) mice (Pdeb rd1 / Pdeb rd1 ) via subconjunctival or retrobulbar injection at postnatal 2 weeks (PN-2w), examined the mice and tested the factors of retina at two weeks after injection. Electroretinogram (ERG) was used to examine retinal function at PN-4w, western blot and q-PCR were used to test the expression of Bax, Bcl-2, iNOS and VEGFa of retina.Result Photoreceptor apoptosis were alleviated in all rhEPO administrated groups. The retinal blood supply was improved in injection groups. Compared with placebo and blank control groups, rhEPO treatment could enhance the retinal function and delay the progression of disease. Although there was no significant difference between rhEPO hydrogel and rhEPO treated group, photoreceptor apoptosis in rhEPO hydrogel group was less than that in rhEPO group, and the retinal function was better in rhEPO hydrogel group. Moreover, different routes of administration might have little effect on treatment in this research.Conclusion Early intervention can effectively control the progression of the disease. Anti-apoptosis,neuroprotection and erythropoietin of rhEPO could be useful in the treatment of RP. Hydrogel as a long-lasting drug sustained release system was stable and available, and might become a potential drug carrier in the future.
