Aim. To substantiate the choice of an extractant when obtaining extractions of the overground part of Lespedeza bicolor.
Materials and methods. The study object was the crushed overground part of Lespedeza bicolor. Extraction was carried out with purified water, 40 % and 70 % water-alcohol solution by the method of fine maceration and using a device for ultrasound extraction. Analytical studies were performed by the appropriate identification reactions, by the method of thin-layer chromatography on Silica gel 60 chromatographic plates of the Merk company; spectrophotometric tests were carried out on an Evolution 60s spectrophotometer using reagents meeting the requirements of the State Pharmacopoeia of Ukraine.
Results and discussion. Chemical reactions identified the presence of flavonoid substances, phenols, tannins, and hydrocarbons in aqueous and alcoholic extracts of Lespedeza bicolor. Tannins identified by thin-layer chromatography were structurally similar to pyrogallol, polysaccharides were structurally similar to fructose, most flavonoids were similar to rutin, and most hydroxycinnamic acids were similar to chlorogenic acid. By the spectrophotometric method it was found that extraction with 40 % and 70 % water-alcohol solution contributed to a more complete extraction of flavonoids similar in structure to rutin, and 40 % ethanol gave substances of the polyphenolic structure calculated with reference to gallic acid.
Conclusions. Based on the research results, tannins, flavonoid substances, phenols and hydrocarbons have been identified in aqueous and alcoholic extractions of Lespedeza bicolor. A more complete extraction of polyphenols with 40 % ethanol, and flavonoids with 40 and 70 % ethanol has been experimentally confirmed. It has been experimentally found that in a ratio of 1:7.5, extractions contain more BAS, but their more complete extraction occurs in a ratio of 1:10. The studies have shown the prospects of using an ultrasonic device for the medicinal raw plant material extraction as it makes it possible to intensify the extraction of BAS compared to the maceration method.

Published: April 2024

New trends were introduced in using PhotoVoltaic (PV) energy which are mostly attributable to new laws internationally having a goal to decrease the usage of fossil fuels. The PV systems efficiency is impacted significantly by environmental factors and different faults occurrence. These faults if they were not rapidly identified and fixed may cause dangerous consequences. A lot of methods have been introduced in the literature to detect faults that may occur in a PV system such as using Current-Voltage (I-V) curve measurements, atmospheric models and statistical methods. In this paper, various machine learning techniques in particular supervised learning techniques are used for PV array failure diagnosis. The main target is the identification and categorization of several faults that may occur such as shadowing, degradation, open circuit and short circuit faults that have a great impact on PV systems performance. The results showed the technique’s high ability of fault diagnosis capability. The K-Nearest Neighbor (KNN) technique showed the best fault prediction performance. It achieves prediction accuracy of 99.2% and 99.7% Area Under Curve-Receiver Operating Curve (AUC-ROC) score. This shows its superiority in fault prediction in PV systems over other used methods Decision Tree, Naïve Bayes, and Logistic Regression.

Published: April 2024

Meningkatkan keselamatan pasien terhadap populasi rentan di pelayanan kesehatan merupakan sebuah prioritas. Pasien dengan disabilitas merupakan salah satu populasi yang rentan. Penyandang disabilitas memiliki kebutuhan perawatan kesehatan yang lebih besar dan lebih kompleks dibandingkan dengan pasien yang bukan sebagai penyandang disabilitas. Studi literatur ini bertujuan untuk mengidentifikasi jenis-jenis insiden keselamatan pasien yang dapat terjadi pada pasien penyandang disabilitas. Pencarian artikel dilakukan dengan menggunakan database Pubmed dan Google Scholar dengan kata kunci “patient safety” dan “disability”. Hasil akhir ditemukan 4 artikel yang memenuhi kriteria inklusi. Hasil temuan mengungkapkan bahwa pasien dengan disabilitas mengalami kejadian insiden keselamatan pasien berupa jatuh, kesalahan pengobatan, infeksi, luka bakar, dan kebocoran cairan pada bawah kulit. Berdasarkan analisis menggunakan kerangka kerja Donabedian, temuan mengungkapkan bahwa masih banyaknya masalah yang terjadi pada komponen struktur dan proses sehingga dapat berdampak pada terjadinya insiden seperti pasien jatuh, kesalahan pengobatan, infeksi, cedera tekanan, luka bakar, dan kebocoran cairan pada bawah kulit serta kerusakan fisik, atau penambahan lama hari rawat inap. Kerentanan dan keunikan yang dimiliki oleh pasien dengan disabilitas menyebabkan populasi ini lebih berisiko mengalami insiden keselamatan pasien. Selain itu, isu disabilitas dan keselamatan pasien masih belum menjadi isu utama sehingga kajian terkait disabilitas dan keselamatan pasien masih terbatas.

Published: April 2024

The present study was accomplished to scrutinize the efficiency of Nano silicon (NSi) as a foliar spray on (Coriander sativum) plants under water stress conditions during 2021/2022 season. Coriander plants were subjected to three water levels (100, 70 and 30% of field capacity). Plant leaves were sprayed with NSi in three different concentrations (3, 5 and 10 ppm) 14 days after germination. The results revealed that Coriander plants growth was significantly decreased under water stress, while NSi treatment showed a significantly enhanced plant growth (length and number of leaves per plant). Regarding biochemical constituents activity, total of alkaloids, phenol, flavonoids and fatty acids increased under water stress. Also, nutrient elements (P & Mg and Na) increased. Plant hormones such as gibberellic acid (GA3) and ascorbic acid (vitamin C) significantly decreased under both 70% and 30% FC, while abscise acid (ABA) increased. In the interim, the three different concentrations of NSi significantly improved carbohydrates concentration and adjustment of osmotic stress. Application of NSi at different concentrations significantly improved nutrients contents (N, P, K, Mg, Ca, Fe, Zn, Mn) mainly under moderate and severe water stress (70%, 30% FC). Generally, the profound concentration of NSi tested during the experiment was 5 ppm for ameliorating water stress. The present investigation showed that the application of NSi might be a promising method to enhance the plant growth, biochemical ingredients and crop productivity of Coriander plants grown under water stress conditions.

The anticipated timeline for muscle strength as well as return to running and sports are some of the most common inquiries by patients undergoing anterior cruciate ligament reconstruction. Despite the popularity of this procedure, the answers to these inquiries are not well described in the literature. The purpose of this study was to evaluate the range of quadriceps strength percentage and function benchmarks at various points after anterior cruciate ligament reconstruction surgery based on sex, age, and graft. Design Observational Cohort Study Methods Patients who underwent anterior cruciate ligament reconstruction (ACLR) were evaluated at various points after their surgery with handheld dynamometer assessments. Additional hop and balance testing was performed and patients were evaluated for clearance for running and sport via a physical therapist directed functional movement assessment (FMA). The progression of quadriceps symmetry throughout the postoperative period was examined with multi-level models, estimates of time to reach 70%, 80%, and 90% quadriceps symmetry were obtained from the fitted model. Results A total of 164 patients were evaluated. Patients either received bone-tendon-bone (BTB) autograft (n=118) or BTB allograft (n=46) for their ACL graft. Average age was 31.1 years-of-age (SD: 13.6). Males undergoing ACLR using BTB autograft (n=53) were able to achieve 80% quadriceps symmetry earlier than females (n=65) (5.7 months vs 7.1 months), were cleared to return to run sooner (5.6 months vs 6.8 months) and passed an FMA exam earlier (8.5 months vs 10 months). Males undergoing ACLR with allograft (n=13) were able to achieve 80% quadriceps symmetry earlier than females (n=33) (3.9 months vs 5.4 months) and were cleared to run sooner (4.5 months vs 5.8 months). Conclusion Patients undergoing BTB autograft obtain 80% quadriceps symmetry at an average of 5.7 months for males and 7.1 months for females. Individuals under the age of 25 obtain their quadriceps symmetry faster and are cleared to return to running faster than individuals over 25. Male sex is associated with decreased amount of time to obtain clearance for running and for full activity. Male sex is associated with decreased amount of time to regain quadriceps symmetry however this was not significant. Level of Evidence 4 (Case series)

Published: April 2024

Background Static balance is often impaired in patients after ankle sprains. The ability to identify static balance impairments is dependent on an effective balance assessment tool. The Sway Balance Mobile Application (SWAY App) (Sway Medical, Tulsa, OK) uses a smart phone or tablet to assess postural sway during a modified Balance Error Scoring System (mBESS) assessment and shows promise as an accessible method to quantify changes in static balance after injury. Purpose The primary purposes of this study were to determine the ability to differentiate between those with ankle sprain versus controls (construct validity) and ability to detect change over time (responsiveness) of a mBESS assessment using a mobile device application to evaluate static balance after an acute ankle sprain. Study Design Case-control study. Methods Twenty-two military academy Cadets with an acute ankle sprain and 20 healthy Cadets were enrolled in the study. All participants completed an assessment measuring self-reported function, ankle dorsiflexion range of motion (via the weightbearing lunge), dynamic balance, and static balance. Static balance measured with the mBESS using the SWAY App was validated against laboratory-based measures. Cadets with ankle sprains completed their assessment twice: once within two weeks of injury (baseline) and again after four weeks of rehabilitation that included balance training. Independent and paired t-tests were utilized to analyze differences over time and between groups. Effect sizes were calculated and relationships explored using Pearson’s correlation coefficients. Results The mBESS scores measured by the SWAY App were lower in participants with acute ankle sprains than healthy Cadets (t = 3.15, p = 0.004). Injured participants improved their mBESS score measured by SWAY at four weeks following their initial assessments (t = 3.31, p = 0.004; Baseline: 74.2 +/- 16.1, 4-weeks: 82.7 +/- 9.5). The mBESS measured by the SWAY App demonstrated moderate to good correlation with a laboratory measure of static balance (r = -0.59, p < 0.001). Conclusion The mBESS assessed with a mobile device application is a valid and responsive clinical tool for evaluating static balance. The tool demonstrated construct (known groups) validity detecting balance differences between a healthy and injured group, concurrent validity demonstrating moderate to good correlation with established laboratory measures, and responsiveness to changes in static balance in military Cadets during recovery from an acute ankle sprain.
