OBJECTIVE
Mechanical endovascular thrombectomy (EVT) is an increasingly relied-on treatment for clot retrieval in the context of ischemic strokes, which otherwise are associated with significant morbidity and mortality. Despite several known risks associated with this procedure, there is a high degree of technical heterogeneity across both centers and operators. The most common procedural complications occur at the point of transfemoral access (the common femoral artery), and include access-site hematomas, dissections, and pseudoaneurysms. Other interventional fields have previously popularized the use of ultrasound to enhance the anatomical localization of structures relevant to vascular access and thereby reducing access-site complications. In this study, the authors aimed to describe the ultrasound-guided EVT technique performed at a large, quaternary neurovascular referral center, and to characterize the effects of ultrasound guidance on access-site complications.

METHODS
A retrospective chart review of all patients treated with EVT at a single center between January 2013 and August 2020 was performed. Patients in this cohort were treated using a universal, unique, ultrasound-guided, single-wall puncture technique, which bears several theoretical advantages over the standard technique of arterial puncture via palpation.

RESULTS
There were 479 patients treated with EVT within the study period. Twenty patients in the cohort were identified as having experienced some form of access-site complication. Eight (1.67%) of these patients experienced minor access-site complications, all of which were groin hematomas and none of which were clinically significant, as defined by requiring surgical or interventional management or transfusion. The remaining 12 patients experienced arterial dissection (n = 5), arterial pseudoaneurysm (n = 4), retroperitoneal hematoma (n = 2), or arterial occlusion (n = 1), with only 1.04% (5/479) requiring surgical or interventional management or transfusion.

CONCLUSIONS
The authors found an overall reduction in total access-site complications as well as minor access-site complications in the study cohort compared with previously published randomized controlled trials and observational studies in the recent literature. The findings suggested that there may be a role for routine use of ultrasound-guided puncture techniques in EVT to decrease rates of complications.

Rhododendron luteum Sweet of the Heath family Ericaceae is found on the territory of Ukraine both in the wild and is widely cultivated in botanical gardens, parks, squares. Leaves and inflorescences are used to treat heart disease, rheumatism, gout, and disorders of the nervous system. The literature data on the chemical composition relate to the presence of aminoacids, organic acids, essential oils, phenolic and triterpene compounds, andromedol derivatives.
The aim of the work was to determine the composition and content of fatty and organic acids in the Rhododendron luteum Sweet leaves by gas chromatography-mass spectrometry.
The object of the study was the leaves of Rhododendron luteum Sweet, collected on the territory of the botanical garden of H. S. Skovoroda Kharkiv National Pedagogical University in 2019. Gas chromatography - mass spectrometric study of the component composition and content of fatty and organic acids in the leaves of the studied plant on an Agilent Technologies 6890 chromatograph with a 5973 mass spectrometric detector was carried out.
In Rhododendron luteum Sweet leaves 37 substances were found and identified. Fatty acids were represented by 17 compounds. Among saturated fatty acids, palmitic acid (3 276.2 mg/kg) was prevailed, among monounsaturated – oleic (736.78 mg/kg), among polyunsaturated – linolenic (1 617.65 mg/kg). The smallest amounts contained heneukocylic (46.33 mg/kg), lauric (58.17 mg/kg) and caproic (68.17 mg/kg) acids, which belong to saturated fatty acids. The presence of 20 organic acids in the raw material was also established: citric (8 680.30 mg/kg) and iso-citric (4 106.85 mg/kg) acids dominated in terms of quantitative content; oxalic (1 685.65 mg/kg) and malic (1 310.82 mg/kg) acids were contained in significant amounts. Among the derivatives of hydroxybenzoic acid, the greatest amount was presented by gentisic (187.76 mg/kg) acid, among the derivatives of hydroxycinnamic acids – p-coumaric (312.62 mg/kg).
For the first time, the qualitative composition and quantitative content of fatty and organic acids in Rhododendron luteum Sweet leaves was studied by gas chromatography with a mass spectrometric detector. The obtained results indicate the prospects for further study of raw materials to develop drugs with membrane stabilizing and anti-inflammatory activity.

Authors: Abdullahi Muhammad , Musa Hamisu 
Published: July 2021

This paper modified an existing 3–point block method for solving stiff initial value problems. The modification leads to the derivation of another 3 – point block method which is suitable for solving stiff initial value problems. The method approximates three solutions values per step and its order is 5. Different sets of formula can be generated from it by varying a parameter ρ ϵ (-1, 1) in the formula. It has been shown that the method is both Zero stable and A–Stable. Some linear and nonlinear stiff problems are solved and the result shows that the method outperformed an existing method and competes with others in terms of accuracy

Authors: Adhidhuto Linus Setyo 
Published: July 2021

Candi Mendut hanya berjarak 27 meter dari jalan raya. Banyaknya kendaraan yang melintas pada jalan tersebut terutama kendaraan berat seperti truk dan bus menimbulkan kekhawatiran akan kelestarian candi tersebut. Getaran yang timbul dari kendaraan tersebut bila mengenai struktur candi dengan frekuensi tertentu dan dalam intensitas yang besar akan berpotensi menimbulkan kerusakan pada candi.
Pengukuran respon getaran dilakukan pada bagian atap dan lantai candi untuk dapat mengetahui apakah getaran yang timbul akibat lalu lintas telah melebihi batas ambang getaran. Pengukuran getaran menggunakan accelerograph yang dapat mengukur getaran dalam 3 arah / triaxial. Untuk dapat mengetahui faktor-faktor yang mempengaruhi besarnya getaran yang timbul maka dilakukan percobaan respon getaran pada tanah dengan variasi kecepatan kendaraan dan berat kendaraan.
Dari pengukuran yang telah dilakukan pada Candi Mendut, ternyata respon getaran yang dihasilkan akibat lalu lintas jalan raya masih di bawah batas ambang getaran. Dari hasil percobaan juga diketahui bahwa kecepatan dan berat kendaraan berbanding lurus dengan besarnya getaran yang ditimbulkan.

Andesite rock is commonly used as a heritage building in Southeast Asia, especially in Indonesia. However, the study on consolidation of andesite rock is still limited. This study aimed to evaluate the application effectiveness of TEOS-based material on the andesite type rock in heritage materials. TEOS was used as a modular system with andesite powder to form mortar. This andesite-TEOS mortar system was applied to conservation techniques, especially for gap and joint filling.
TEOS modular system was successfully applied to the andesite type rock, resulting in chemical and physical properties. The color of the mortar and the compatibility with the original rock color were designed from the rock powder preparation. The excellent repair was obtained by a combination of dot technique gluing using epoxy resin and the TEOS mortar application in the gaps. Furthermore, this technique was successfully applied to the big Buddha Statue Head andesite rock for the emergency intervention of the falling fragment.

PurposeSynchronous peritoneal metastasis (S-PM) is considered a poor prognostic factor for colorectal cancer (CRC) and there is no nomogram to predict the survival of these patients. In this study, we aimed to use a multicenter data to identify the factors associated with S-PM of CRC to construct a nomogram for predicting the overall survival (OS) of these patients.MethodsCRC patients with S-PM from two medical centers were enrolled between September 2007 and June 2017. Multivariate analysis was used to identify independent factors associated with OS for the nomogram to predict the 1-, 2-, and 3-year OS rates in the development group. The concordance index (C-index), calibration plot, relative operating characteristic (ROC) curve with area under the curve (AUC) were calculated to evaluate the performance of the nomogram in both the development and an external validation group.Results277 CRC patients with S-PM in the development group and 68 patients in the validation group were eligible for this study. In multivariate analysis of development group, age, carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 125 (CA125), cytoreductive surgery (CRS), hyperthermic intraperitoneal chemotherapy (HIPEC), and chemotherapy were independent variables for OS, based on which the nomogram was built. The C-index of the nomogram in the development and validation group was 0.701 (95% Cl, 0.666–0.736) and 0.716 (95% Cl, 0.622–0.810); demonstrating good discriminative ability. The calibration plots showed satisfactory consistency between actual observation and nomogram-predicted OS probabilities in the development and external validation group. The nomogram showed good predictive accuracy for 1-, 2-, and 3-year OS rates in both groups with AUC &gt;0.70. An online dynamic webserver was also developed for increasing the ease of the nomogram.ConclusionsWe developed and validated a predictive nomogram with good discriminative and high accuracy to predict the OS in CRC patients with S-PM.
