Published: June 2022

AIM: To determine the group of patients with trigeminal neuralgia for whom the balloon microcompression is the optimal treatment modality. To evaluate the effectiveness of balloon microcompression in the treatment of patients with trigeminal neuralgia.

MATERIALS AND METHODS: The study included 52 patients (18 men and 34 women) with trigeminal neuralgia who were operated with the use of balloon microcompression in neurosurgical department of the Samara Regional Clinical Hospital named after V.D. Seredavin over the period from February 2012 to June 2017. The evaluation of effectiveness was carried by Visual Analogue Scale, Macnub scale, the dose tapering of anti-epileptic medicines was also taken into account.
RESULTS: In postoperative period the decrease in pain syndrome was noticed by 48 patients (92.3%) from 90 10 to 30 10 points by Visual Analogue Scale. According to Macnub scale 29 patients (55.7%) estimated the level of treatment as good. 19 patients (36.5%) had negative emotional response due to the hypoesthesia, so the result was estimated as satisfactory. 39 patients (75%) managed to decrease the dosage of Finlepsin from 1000-1200 mg to 300-400 mg. Among them there were 8 patients (15%) who subsequently discontinued taking Finlepsin.
CONCLUSIONS: Balloon microcompression of Gasserian ganglion is a destructive-symptomatic method that must be considered the main modality only in patients with idiopathic trigeminal neuralgia or with contraindications for operative treatment. Balloon microcompression of Gasserian ganglion is a minimally destructive treatment mode, which allows to increase the effectiveness of treatment due to the alleviation of pain paroxysm in the area of trigeminal innervation and the decrease in dosage of anti-epileptic medicine.

BACKGROUND: The favorable outcome after the restoration of bone loss in the jaws depends on many factors. Thus, one of the key factors is the data on the mechanical and biophysical characteristics of the used bone implants, ignorance of which often jeopardizes the successful treatment of dental patients.

AIM: To carry out a comparative experimental analysis of the stress-strain state of a digital model of a reconstructive lyophilized allogeneic bone implant with a change in its design characteristics.
MATERIALS AND METHODS: To determine the biomechanical indicators of integrity preservation, the analysis of the stress-strain state of mathematical models of a reconstructive cylindrical implant and a reconstructive implant made of lyophilized allogenic material was carried out under equal conditions using the finite element method.
RESULTS: As a result of the analysis of the stress-strain state of digital 3D models of reconstructive bone implants of two types, stress distributions according to von Mises (equivalent stresses) caused by the action of given loads were obtained. During the study, data on the margin of safety of reconstructive implants were obtained.
CONCLUSIONS: The capabilities of modern computer software make it possible to expand the possibilities of bone augmentation of the alveolar bone tissue of the jaws with simultaneous dental implantation, allowing analytically to find the optimal parameters of the used materials, to choose the magnitude and direction of force during their installation, and also to predict their behavior in the postoperative period.

AIM: The purpose of this work is to develop and use the method for the quantitative determination of Aloe vera leaves (Aloe vera L. ex Webb) using UV spectrophotometry.

MATERIALS AND METHODS: Since the method of quantitative determination of Aloe vera leaves in the State Pharmacopoeia of the Russian Federation XIV edition is not available, it was developed at the Department of Pharmaceutical Economics and Management, Pharmaceutical Technology and Pharmacognozy of Orenburg State Medical University. According to this method the optimal conditions for the extraction of anthracene derivatives in aloe vera leaves are the following: extractant was 96% ethyl alcohol); the ratio of raw material and extractant was 1:10; extraction time was the extraction in a boiling water bath for 30 minutes and 15 minutes in an ultrasonic bath. The registration of the spectra was performed with the use of Unico 2800 spectrophotometer in the wavelength range of 190-700 nm in cuvettes with the layer thickness of 10 mm, Vilitec VBS ultrasonic bath. The UV spectra of water-alcohol and alkali-ammonia solutions of Aloe vera leaves were investigated.
RESULTS AND DISCUSSION: The quantification of the of anthracene derivatives (calculated on barbaloin) in Aloe vera leaves was carried out with the use of methodology that determines anthracene derivatives directly in the test solution without acid hydrolysis and oxidation of anthraglycosides. The developed method of quantitative analysis allowed to determine the content of the total anthracene derivatives in terms of barbaloin in fresh leaves of aloe vera, the content ranged from 3.0-5.0% (calculated on dry-air plant material).
CONCLUSIONS: It was found that the content of the total anthracene derivatives in Aloe vera leaves calculated on barbaloin is 3.33%.

Erosion is the most dangerous phenomenon of environmental and economic threat to arable land. By FAO. 35 % of Tunisian land are threatened by water erosion and varies regionally. Quantification and estimation of soil loss by water erosion is now essential to install the best management practices. In our study, we used a continuous physical based simulation version of a hydrological and water erosion model ANSWERS-2000. The aim of this study is to investigate the introduction of land use parameters extracted by MODIS image. This study is focused on El Azire watershed, is characterized by a moderate Mediterranean climate and a high spatial heterogeneity of soil and land use proprieties. Describing, monitoring, and predicting land-use and land-cover change in the watershed is a difficult process. However, the usefulness of MODIS image with their daily temporal resolution and spatial resolutions of 250 m and 500 m can make utilization of continuous physical-based models easier for great scale watersheds. A sensitivity analysis was conducted on each application such that the variability in erosion map output and can be assessed and incorporated into the interpretation of results with an acceptable level of confidence.

Published: June 2022

The biological proprieties of mucilaginous polysaccharides (PSc) extracted from Tossa jute leaves (Corchorus olitorius L.) using an ethanol precipitation method were studied. The results showed that PSc had higher total polyphenols and flavonoids and greater antioxidant activities. At 1.5 mg/ml PSc, the antioxidant activities were about 90% against 1,1-diphenyl-2-picryl hydrazyl radical (DPPH•) and 78% against lipid peroxidation. The PSc with a FRAP assay at the same concentration showed an effective protection against hydroxyl radicals and DNA breakage. Furthermore, the extracted PSc had a wide spectrum of antibacterial activities against all bacteria tested (Gram+ and Gram-). The overall data suggested that this natural PSc may be used as a competitive antioxidant and antimicrobial additive in food and in medicinal preparations.

Abstract
Post–severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (coronavirus disease 2019 [COVID-19]) conditions are referred to by a wide range of names, including long COVID, post-acute COVID-19, long-term effects of COVID, post-acute COVID syndrome, chronic COVID, long-haul COVID, late sequelae, and others, as well as the research term, post-acute sequelae of SARS-CoV-2 infection (PASC). Symptoms may include difficulty thinking or concentrating, fatigue, depression, anxiety, and other complaints. The results of studies are clouded by self-reports, lack of objective cognitive data, misattribution, and ill-defined psychological issues. Prospective cohort studies with objective assessment are needed to clarify the impact of COVID-19. While we do not dismiss the presence of long COVID or chronic COVID-19 symptoms lasting beyond a typically expected viral respiratory-transmitted syndrome, neither do we uncritically accept such a syndrome in all those who were diagnosed as having COVID-19, especially in those whose initial presentation was asymptomatic or mild. Evaluators must be astute and perform unbiased, thorough assessments and focus on objective findings while carefully assessing the potential for confounding or alternate conditions.

Algebraic graph theory, Lyapunov stability and fixed‐time theory are used to prove the fixed‐time bipartite consensus. In order to reduce control cost, an adaptive control protocol is further designed and discussed. Finally, the feasibility of the developed control methods are verified by numerical simulations.
A Programmable Electrochemical Y‐Shaped DNA Scaffold Sensor for the Single‐Step Detection of Antibodies and Proteins in Untreated Biological Fluids

Published: June 2022

AbstractProteins and antibodies are key biomarkers for diagnosing and monitoring specific medical conditions. Currently, gold standard techniques used for their quantification require laborious multi‐step procedures, involving high costs and slow response times. It is possible to overcome these limitations by exploiting the chemistry and programmability of DNA to design a reagentless electrochemical sensing platform. Specifically, three DNA single strands are engineered that can self‐assemble into a Y‐shaped DNA nanostructure that resembles one of the IgGs. In order to convert this DNA nanostructure into a responsive DNA‐scaffold bioreceptor, it is modified including two recognition elements, two redox tag molecules, and a thiol group. In the absence of the target, the scaffold receptor can efficiently collide with the electrode surface and generate a strong electrochemical signal. The presence of the target induces its bivalent binding, which produces steric hindrance interactions that limit the receptor's collisional activity. In its bound state, the redox tags can therefore approach the surface at a slower rate, leading to a signal decrease that is quantitatively related to the target concentration. The Y‐shape DNA scaffold sensor can detect nanomolar concentrations of antibodies and proteins in <15 min with a single‐step procedure directly in untreated biological fluids.

AbstractAlthough significant progress is achieved for the synthesis of noble metal‐based nanocrystals (NCs), the construction of nanostructures with switchable dimensionality is not reported yet. Herein, a facile and general approach for the synthesis of multimetallic (PtCuPb and PtAgPb) NCs with dimensional‐switching properties by manipulating the reduction rate involved in the growth of 2D nanosheets (2D‐NS) and 1D nanowires (1D‐NW) is presented. At a slow reduction rate, PtCuPb and PtAgPb NCs grow to form 2D‐NS, in contrast, at a fast reduction rate, dimensionality alteration occurs to form 1D‐NW. This 2D‐NS to 1D‐NW transition generates compressive surface strain in PtCuPb‐NW with unique intermetallic core, active surface composition and exposes facet to boost oxygen reduction reaction (ORR). In PtCuPb‐NW, compressive strain shifting the d‐band electronic structure of platinum and weakening chemisorption of oxygenated species are shown. In detail, PtCuPb‐NW/C exhibits superior specific and mass activities (4.91 mA cm−2 and 2.65 A mgPt−1) for ORR that are ≈19 and ≈15 times higher than the commercial Pt/C. The observations made and chemical principles unveiled in this effort indicate that a general approach exists for dimensional‐switching and show a new class of Pt‐based electrocatalysts with enhanced performance for fuel cells.
