Published: February 2022

Pendidikan di Indonesia menjadi salah satu bidang yang terdampak akibat adanya pandemi covid-19. Dengan adanya pembatasan interaksi, Kementerian Pendidikan di Indonesia juga mengeluarkan kebijakan yaitu dengan meliburkan sekolah dan mengganti proses Kegiatan Belajar Mengajar (KBM) dengan menggunakan sistem dalam jaringan (daring), Pembelajaran Jarak Jauh (PJJ) dan Belajar Dari Rumah (BDR). Dengan menggunakan sistem pembelajaran secara daring ini, muncul berbagai masalah yang dihadapi oleh siswa dan guru. Mulai dari faktor ekonomi (siswa tidak memiliki Gadget), sinyal yang buruk, minimnya pengetahuan orang tua dalam digitalisasi pembelajaran dan lain sebagainya. Untuk itu dibutuhkan keratifitas dan inovasi pembelajaran dari seorang guru. Kreativitas adalah fungsi dari tiga komponen utama: keahlian, keterampilan berpikir kreatif, dan motivasi. Keahlian terdiri dari pengetahuan: teknis, prosedural, dan intelektual. Sederhananya, kreativitas menghasilkan orang yang melihat sesuatu secara berbeda.

Aims: Polymethylsilsesquioxane (PMQS) is a silicone derivative that serves as a skin conditioning agent and moisturizer in cosmetics. The objective of this study is to identify the effect of different concentrations PMSQ (0.12, 0.20 and 0.35 wt %) on liquid foundation (LF) and find the optimized composition in vitro.
Study Design: Structural and morphological features of the examined nano/micro-sized samples were investigated by different methods.
Place and Duration of Study: Hacettepe University, Department of Physics Engineering, X-Rays Laboratory, between September 2017 and September 2019.
Methodology: Micro/nano scale structural and morphological properties of samples were investigated by means of a multi-methodological approach based on Small‐ and/or Wide‐Angle X‐ray Scattering (SWAXS), Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM/EDX), Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) Spectroscopy and UV-vis Spectroscopy. The LF (control) and PMSQ-LF films at one-week intervals for 4 weeks, and bovine leather coated samples with LF and PMSQ-LF were also investigated by SWAXS. The effect of PMSQ on biofilm formation activity in E. coli and S. aureus were also examined.
Results: The most significant finding of this study is that even the low concentration of polymer in LF showed differences in nano structure and it was found that a decrease in biofilm formation. Nano formation becomes more pronounced, and the number of agglomerations decreases after 4 weeks. The reason for the study over a 4-week period was the desire to take into account the independent effect of each LF use, as well as the periodic stacking and diffusing effect that will occur in the depths of the skin over time. In the UVA range (320-400 nm) lower transmittance values were found for LF and PMSQ - LF films.
Conclusion: The results suggest that optimum polymer concentration in liquid foundation should be considered as a main step. The smart and systematic use of polymer additives is directly manifested in the nanoscopic structure and can improve the harmful UV rays prevention properties, which are important for health as well as cosmetic effects for beauty purposes.

Determination of radionuclides’ activity concentration in fruits is essential for the protection of human health. Fruits can be radioactive due to the present of naturally occurring radioactive materials (NORMs) and technically enhanced radioactive materials (TENORMs) in the environment. The Assessment of Radionuclide activity concentration in Some Fruits from Niger Delta, Nigeria and its Health Risks were carried out using gamma ray spectroscopy. The study measured the activity concentration of radionuclides in fruits and the results showed that the total activity concentration of 40K, 232Th and 226Ra in fruits were 578.24 Bqkg-1, 263.84 Bqkg-1 and 128.35 Bqkg-1 respectively. The study found out that 40K has the highest value of activity concentration while apricot has the highest value of radionuclide concentration compared to other fruits. The statistical analysis of data was also done using statistical packages. The average estimated AED for Infants, Children and Adults due to the radioactivity in Avocado, Apricot, Guava and Pear were; 829.02 µSvy-1, 565.865 µSvy-1, and 838.725 µSvy-1, 2737.665 µSvy-1, 4361.4875 µSvy-1 and 2497.9025 µSvy-1, 651.20833 µSvy-1, 1202.6767 µSvy-1 and 813.22167 µSvy-1, and 1164.7883 µSvy-1, 1724.2933 µSvy-1 and 1088.8933 µSvy-1 respectively. The estimated AED due to the consumption of various fruits are above the world value. However, the estimated excess lifetime cancer risks for the various fruits are far below the world (WHO) limit. The study concluded that there is no cancer risk associated with the consumption of fruits in the study area and that the fruits that have tap root systems recorded highest value of radionuclides’ activity concentration.

Published: February 2022

Background and Aims: Spontaneous bacterial peritonitis (SBP) is defined as a bacterial infection of the ascitic fluid (AF) that arises in individuals without an intra-abdominal source of infection that is surgically curable. SBP is a unique complication in cases with cirrhosis-linked ascites, and it can be so subtle that it is only reported by chance when paracentesis is done. SBP is handled with any of a variety of cephalosporins, such as cefotaxime or quinolones, such as Gemifloxacin. The aim was comparing the effect of oral Gemifloxacin versus intravenous cefotaxime in 60 individuals with cirrhosis who had SBP.
Patients and Methods: The randomized controlled research involved 60 cirrhotic ascitic individuals suffering from SBP admitted to Tropical Medicine Department, Tanta University Hospital. Two groups of patients were investigated: group I included 30 cirrhotic ascitic patient suffering from SBP treated with IV cefotaxime 2gm|8 hours for 7 days and group II included 30 cirrhotic ascetic patient suffering from SBP and treated with oral Gemifloxacin 320 mg once daily for 7 days.
Results: No substantial difference was noted among both groups regarding age, sex, or symptoms, or in laboratory tests such as hemoglobin, total leukocytic count, platelet, serum bilirubin, ALT, AST, albumin, prothrombin activity, INR, creatinine, urea, sodium, and potassium. Also, the outcome was comparable in both groups as regarding the number of treated patients (p=0.781); 20 (66.67%) cases were cured in group I and 21 (70%) cases were cured in group II and in AF analysis after treatment. By using gram stain, gram –ve organism were the predominant in group I 23 (76.7%) and group II 24 (80%) while gram +ve was detected in 7 (23.3%) and 6 (20%) in group I and II respectively. Furthermore, no substantial difference was noted among both groups regarding treatment response based on culture prior to treatment.
Conclusions: Our research is the first to focus on Gemifloxacin use in the management of SBP rather than in the prevention of SBP. Since these agents' relative effectiveness is identical, cost should be the deciding factor. In conclusion, our findings indicate that cefotaxime or Gemifloxacin can be used as a first-line therapy.

Authors: Dhok Harsha , Beg Sana 
Published: February 2022

Introduction: The WHO (World Health Organization) declared COVID-19, a worldwide pandemic caused by a novel variant of the corona virus 2019-nCoV, as a worldwide pandemic in 2020. As a preventative step, the Indian government imposed a countrywide lockout for 21 days, restricting people's movement. During the shutdown, a study was devised and completed to analyze the impact on eye care and patient care in India. Methods: Through various social media platforms, an online survey was sent to the practice of Indian ophthalmologists. We arranged and analyzed all of the validated responses.
Summary: The poll received responses from 1260 ophthalmologists. 61.5 percent of respondents worked in a private clinic, whereas 14.8 percent worked in an eye institute. Due to the lockdown of those who were still evaluating patients at the time of the poll, 72.5 percent of respondents did not perceive any patients, and 82.9 percent (287/347) were only looking at emergency cases, based on their own clinical judgement. The percentage of ophthalmologists who were still examining patients in eye facilities, municipal and government hospitals (49.8%) was significantly higher (p0.0001) than in private clinics. Other procedures that were still being performed included intravitral injections, in addition to causes such as trauma, retinal detachment, and endophthalmities (81.8 percent) (9.1 percent) and cataract surgery (5.9%). Since the lockdown began, around 77.5 percent of respondents have begun telephone, e-mail, video call, or social media application counseling. Furthermore, 59.1% said that when examining patients, ophthalmologists were at a larger risk of getting COVID-19 than other disciplines. When asked when they would resume practice when once restrictions were relaxed 57.8% of respondents said they were unsure when they would resume elective surgery In addition, 62.8% percent said they were unsure of the preferred screening strategy or precautionary approach before beginning surgery and were awaiting guidelines.
Conclusion: According to our research, most ophthalmologists in India were unable to assess patients during the COVID-19 lockdown, and many of them had to undergo elective surgery. 27.5 percent of those who responded to the emergency room were ophthalmologists. To aid patients, ophthalmologists had shifted to telephonic guidance or other forms of telemedicine. Whether the COVID-19 reduced regulations, most responding ophthalmologists were unsure when and how to resume operations. Regulatory agencies should be aware of this and give appropriate guidelines.

Authors: Gheni Aqeel Ismael , Hasan Ayad H. 
Published: February 2022

Aims: The widespread usage of commercially accessible antibacterial agents has resulted in the emergence of multidrug-resistant bacterial pathogens worldwide. Streptomycetes produce a variety of antibacterial secondary metabolites and the study, as a result, will look into the antibacterial potential of Streptomyces coelicolor against some pathogenic bacteria.
Place and Duration of Study: The study was based at the department of Medical Microbiology, Science and Health research center, Faculty of science and health, Koya University. between April, 2019 and December, 2020.
Methodology: The Streptomyces coelicolor strains in this study were verified phenotypically via tryptone soya agar in addition to their genotype using three different sets of primers. Afterwards, Thin Layer Chromatography (TLC) was utilised to purify actinorhodin from the crude extract of S. coelicolor secondary metabolites. The antibacterial activities of the actinorhodin and the crude extract have further been tested against standard strains of Staphylococcus aureus (ATCC 25923), Streptococcus pyogenes (ATCC 19165), Escherichia coli (ATCC 25218), and Salmonella typhi (ATCC 14028). Disc diffusion and minimum inhibitory concentration (MIC) techniques were both used to serve this purpose.
Results: A significant activity of the organic solvent extract was observed against Staphylococcus aureus and Streptococcus pyogenes using the disc diffusion method with diameter zone inhibition of (9-20 mm) and (11-23 mm), respectively. Actinorhodin, on the other hand, showed a reasonable wider effect against them with diameter zone inhibition of (10-24 mm) against S. aureus and (10-27 mm) against S. pyogenes. Comparatively, the MIC test showed akin results by inhibiting S. aureus and S. pyogenes at a MIC value of 16 µg/ml using crude extract. Whereas actinorhodin expressed greater inhibitory activities against S. aureus, S. pyogenes and S. typhi with MICs of (8, 16 and 32 µg/ml), respectively.
Conclusion: The capability of suggested actinorhodin from the L646 strain to inhibit Staphylococcus aureus and Streptococcus pyogenes growth with a MIC value of 8 g/ml was a remarkable finding obtained by studying Streptomyces coelicolor secondary metabolites.
