However, ophthalmic preparations also have some limitations, one of which is the rapid elimination of the drug, that reducing the effectiveness of the drug. Accordingly, an alternative delivery approach can be applied to overcome this issue. Additionally, as one of critical steps in the formulation development, analyitical methods that allow the quantification of metronidazole in ex vivo corneal permeation and deposition should also be developed. Here, we report a validated high-performance liquid chromatography method (HPLC-UV) according to ICH guidelines for the measurements of metronidazole concentrations following formulation of thermosensitive ocular in situ gel and its administration in ex vivo porcine corneas. The development of extraction techniques and optimization of HPLC conditions were optimized using analytical quality by design. Xselect™ CSHTM C18 HPLC column (Water, 3.0 × 150 mm, particle size 3.5 m) was used to separate all analytes by isocratic elution with mobile phases of acetate buffer and acetonitrile with LLOQ value of 0.08 μg/mL. The resulting method proved to be selective, precise, and accurate and was succefully applied to determine ocular kinetic profiles of metronidazole from thermosensitive ocular in situ gel in ex vivo porcine corneas, showing that this approach was able to improve the concentration of metronidazole in the corneal tissues. We, therefore, suggested that HPLC-UV approach developed in this study has the potential to be used in drug release evaluation, therapeutic drug control research, ocular kinetics, and toxicological evaluation.

Therefore, researchers strive towards researching and experiments to solve some of the wireless communication system issues. This paper aims to provide wireless communication services using a tethered balloon that can be allocated to provide Internet services to two main applications; 1) remote regions; 2) short-term large-scale events. In order to design our system, this paper presents a helium balloon, smart 5G antenna, and telecommunication payload as the main parts, as well as a suitable propagation model that is modelled with careful consideration of elevation angle to deliver the best possible wireless services. Results infer that the proposed configuration not only could enhance internet connectivity but also empower the internet of things (IoT) and 5G technology in a cost-effective manner with a significant coverage footprint.

Limbah kulit buah nangka diduga juga mengandung metabolit sekunder yang dapat dimanfaatkan sebagai senyawa sumber antioksidan. Penelitian ini bertujuan untuk mengetahui jenis-jenis senyawa yang terdapat pada ekstrak kulit buah dan mengukur aktivitas antioksidannya terhadap ABTS. Golongan senyawa diuji dengan menggunakan pereaksi untuk mengetahui kandungan kimia dalam ekstrak kulit buah nangka berupa antara lain flavonoid, alkaloid, tanin/fenolik, saponin, terpenoid. Profil KLT yang diperoleh menggunakan densitometer menunjukkan nilai Rf 0.27 dan 0.40 kemungkinan merupakan senyawa flavonoid sedangkan pada Rf 0.9 dideteksi positif untuk senyawa terpenoid. Uji aktivitas antioksidan terhadap hasil fraksinasi esktrak kulit buah nangka menujukkan bahwa fraksi 3 menghasilkan nilai IC50 yang paling besar di antara fraksi-fraksi k...

Along with this, the study also attempts to identify the class of compounds present in the various extract of G. hombroniana by the active fraction. The bark extract of G. hombroniana was prepared by the multilevel maceration method by using three solvents including n-hexane, ethyl acetate, and 96% ethanol. Results of study suggested that n-hexane (HSE), ethyl acetate (EASE) and ethanol 96% extract (ESE) have antioxidant activity with IC50 value of 423 ± 16.72 μg/mL, 284.89 ± 2.7μg/mL, and 10.49 ± 0.19 μg/mL in DPPH assay, while these extracts showed IC50 value of 560.92 ± 48.86 μg/mL, 430.18 ± 16.65 μg/mL, and 13.92 ± 0.57 μg/mL respectively in ABTS assay. Further, fractionated using vacuum column chromatography revealed the presence of five fractions viz., A, B, C, D, and E. Among these, fractions D showed the highest antioxidant activity with a...

Limbah kulit buah nangka diduga juga mengandung metabolit sekunder yang dapat dimanfaatkan sebagai senyawa sumber antioksidan. Penelitian ini bertujuan untuk mengetahui jenis-jenis senyawa yang terdapat pada ekstrak kulit buah dan mengukur aktivitas antioksidannya terhadap ABTS. Golongan senyawa diuji dengan menggunakan pereaksi untuk mengetahui kandungan kimia dalam ekstrak kulit buah nangka berupa antara lain flavonoid, alkaloid, tanin/fenolik, saponin, terpenoid. Profil KLT yang diperoleh menggunakan densitometer menunjukkan nilai Rf 0.27 dan 0.40 kemungkinan merupakan senyawa flavonoid sedangkan pada Rf 0.9 dideteksi positif untuk senyawa terpenoid. Uji aktivitas antioksidan terhadap hasil fraksinasi esktrak kulit buah nangka menujukkan bahwa fraksi 3 menghasilkan nilai IC50 yang paling besar di antara fraksi-fraksi k...
