Published: May 2023

A field study was conducted for assessment five different varieties of pomegranate (Tarnab gulabi, NARC-1, NARC-2, Kandhari and Sultan) under subtropical agro-climatic conditions. The investigation was conducted under RCBD (randomized complete block design) with five treatments and three replications. Various morphological (plant height, leaf area), fruit physical (fruit size, fruit weight, seed%, juice % and peel %) and biochemical (TSS, pH, titratable acidity, ascorbic acid contents, total sugars, reducing sugars and non-reducing sugars, total antioxidants and total phenols) parameters were studied. Findings noted were subjected to variance analysis at 5% probability. Wide morph-biochemical variation was observed for most of the examined traits. Results showed that NARC-I showed highest value for fruit weight (224.07g), juice % (34.33%), non-reducing sugars (4.53%), titratable acidity (1.67%) and total antioxidant contents (4.53 DPPH inhibition %age) in juice. Kandhari had maximum seed % (42.67%), peel % (39.23%) and vitamin C (12.13 mg/100ml) contents. Highest plant height (11.23 feet), leaf area (1031.4mm), juice pH (3.43), TSS (19.20 brix), reducing sugars (11.70%) and total phenols (11.70 µg GAE L-1) was observed in Sultan strain. Based on the outcomes of this investigation, it can be concluded that Sultan performed better in terms of vegetative and fruit physical and bio-chemical attributes under subtropical agro-climatic conditions of Faisalabad.

Over algebraically closed fields of positive characteristic, for simple Lie (super)algebras, and certain Lie (super)algebras close to simple ones, with symmetric root systems (such that for each root, there is minus it of the same multiplicity) and of ranks less than or equal to 8—most needed in an approach to the classification of simple vectorial Lie superalgebras (i.e., Lie superalgebras realized by means of vector fields on a supermanifold),—we list the outer derivations and nontrivial central extensions. When the conjectural answer is clear for the infinite series, it is given for any rank. We also list the outer derivations and nontrivial central extensions of one series of non-symmetric (except when considered in characteristic 2), namely periplectic, Lie superalgebras—the one that preserves the nondegenerate symmetric odd bilinear form, and of the Lie algebras obtained from them by desuperization. We also list the outer derivations and nontrivial central extensions of an analog of the rank 2 exceptional Lie algebra discovered by Shen Guangyu. Several results indigenous to positive characteristic are of particular interest being unlike known theorems for characteristic 0, some results are, moreover, counterintuitive.

Authors: Baviera-Puig Amparo , Baviera Tomás , Escribá-Pérez Carmen , Buitrago-Vera Juan
Published: May 2023

Recently, researchers have developed an interest in the analysis of emotional responses to food. For this reason, the use of implicit (non-verbal) measures to assess consumer response is increasing. In this research, the objective is to find out if there were differences in consumer response (conscious and unconscious) to melon of various origins: Spain, Morocco and Brazil. To do this, we used the biometric measures (Electroencephalography (EEG) and Skin Conductance Response (SCR)) and questionnaires to assess various melon attributes. The results reveal that consumers do not respond differently to fruit from different origins, either consciously or unconsciously.

Published: May 2023

Available information on the typification of the name Ranunculus rionii in the literature is scarce and misleading. Previously claimed type collections indicate Lagger as the collector, but the protologue discusses only the specimens collected by Rion. Original material for the name is identified, the locality of the type collection is specified, Lagger’s way of writing herbarium labels for his type specimens is described, the history of the discovery of R. rionii is reviewed, and the name is lectotypified.

Authors: Sierra-Paycha Célio , Mora Manon , Lelièvre Éva
Published: May 2023

L’armée française entretient un lien historique avec les Outre-mer. Dans un contexte de décolonisation de l’empire colonial français, des tentatives de légitimation de l’armée auprès de la population locale ont vu le jour, par exemple le service militaire adapté (SMA). L’armée est aujourd’hui un vecteur d’opportunités professionnelles d’autant plus important dans les département, régions et collectivités outre-mer (DROM-COM) que le taux d’inactivité y est largement supérieur à celui de l’Hexagone. Parmi l’ensemble des jeunesses d’outre-mer, ce sont les Polynésiens qui sont le plus surreprésentés chez les militaires de métier. Cette spécificité est interrogée ici à l’aide des données de recensement, de l’enquête Feti’i e fenua et d’entretiens qualitatifs. La place de l’armée sur le territoire, le rôle de la famille et les particularités du SMA polynésien sont étudiés.

Published: May 2023

The major objective of this scheme is to investigate both the existence and the uniqueness of a solution to an integro-differential equation of the second order that contains the Caputo-Fabrizio fractional derivative and integral, as well as the q-integral of the Riemann-Liouville type. The equation in question is known as the integro-differential equation of the Caputo-Fabrizio fractional derivative and integral. This equation has not been studied before and has great importance in life applications. An investigation is being done into the solution's continued reliance. The Schauder fixed-point theorem is what is used to demonstrate that there is a solution to the equation that is being looked at. In addition, we are able to derive a numerical solution to the problem that has been stated by combining the Simpson's approach with the cubic-b spline method and the finite difference method with the trapezoidal method. We will be making use of the definitions of the fractional derivative and integral provided by Caputo-Fabrizio, as well as the definition of the q-integral of the Riemann-Liouville type. The integral portion of the problem will be handled using trapezoidal and Simpson's methods, while the derivative portion will be solved using cubic-b spline and finite difference methods. After that, the issue will be recast as a series of equations requiring algebraic thinking. By working through this problem together, we are able to find the answer. In conclusion, we present two numerical examples and contrast the outcomes of those examples with the exact solutions to those problems.

Effect of hydroalcoholic leaf extract of Cassia fistula L. on type II collagen-induced arthritis in rats
Authors: Mehta Vineet , Nagu Priyanka , Parashar Arun , Chaudhary Manjusha
Published: May 2023

Objective:

To explore the effect of Cassia fistula on collagen II-induced arthritis in rats.

Methods:

The effect of 250 and 500 mg/kg chloroform and hydroalcoholic extract of Cassia fistula leaf on collagen II-induced arthritis was investigated by evaluating paw volume, arthritis index, spleen index, and biochemical parameters. Histopathological analysis and docking study were also performed.

Results:

A dose-dependent reduction in paw volume, arthritic index, and spleen index was observed following oral administration of the chloroform and hydroalcoholic extracts. Treatment with Cassia fistula extracts reduced tumor necrosis factor-α, interleukin (IL)-1β, IL-6, prostaglandin E2, aspartate aminotransferase, alanine aminotransferase, total leucocyte count, and erythrocyte sedimentation rate while increasing IL-10 level. In addition, Cassia fistula extracts improved joint architecture, and prevented cartilage and bone destruction. Docking analysis demonstrated that the physcion, 1-octacosanol, 5,3',4'-trihydroxy-6-methoxy-7-O-α-L-rhamnopyranosyl-(1,2)-O-β-D-galactopyranoside and scopoletin may be responsible for the anti-arthritic effect of Cassia fistula.

Conclusions:

Cassia fistula suppresses the progression of collagen II-induced arthritis by lowering the inflammatory factors, decreasing paw volume and arthritic index, and alleviating joint architecture. However, further studies are required to confirm the bioactive molecule responsible for the anti-arthritic potential of Cassia fistula.

Published: May 2023

Objective:

To investigate the anti-inflammatory and analgesic effects of Solanum procumbens on complete Freund's adjuvant-induced arthritis rat models.

Methods:

We isolated and identified five compounds in the ethanol-soluble Solanum procumbens extract (SP) with anti-inflammatory effects, including ursolic acid, β-sitosterol, hexadecanoic acid, cis-vaccenic acid, and vanillic acid. Additionally, we investigated the anti-inflammatory effects of SP on rheumatoid arthritis symptoms, including paw volumes, local temperatures, withdrawal latency, and mechanical withdrawal threshold at the hind paw and white blood cell (WBC) number from complete Freund's adjuvant-induced arthritis rat models.

Results:

We have successfully established a complete Freund's adjuvant-induced arthritis rat model at a low dose (1 mg/mL). SP extract significantly reduced paw volumes (P<0.05), prolonged withdrawal latencies (P<0.05), decreased local temperature, and increased the mechanical withdrawal threshold (P<0.05), but only SP extract at the dose of 300 mg/kg significantly decreased WBC numbers.

Conclusions:

SP extract could be a potential medication candidate with anti-inflammatory effects for arthritis, but it requires further investigation into the mechanism of the SP and its effectiveness on other models as well as clinical trials.

Authors: Fathalla Ahmed Mahmoud Fahmy , Abdelazeem Khaled , Kedwany Salma Mohamed , Mohamed Tarek Ahmed , Abdel-Radi Mahmoud , Mostafa Magdi Mohammad , Wasfi Ehab , El-Sebaity Dalia M.
Published: May 2023

Purpose:

To study patient's acceptability and safety of offering a prophylactic early single session of pan-retinal photocoagulation (PRP) for moderate nonproliferative diabetic retinopathy (NPDR) in selected patients.

Settings and Design:

Mixed observational and interventional study.

Patients and Methods:

The observational study included 82 eyes of 68 patients presenting with proliferative diabetic retinopathy (PDR) or its complications and the interventional study included 48 eyes of 48 patients with moderate NPDR who were offered a single session PRP because they were unlikely to comply with the follow-up protocol and were at higher risk of diabetic retinopathy (DR) progression.

Results:

The observational study showed that nearly 51% of patients had no idea about the DR screening protocols, 47.5% of included eyes presented with vitreous hemorrhage, 30.5% with tractional retinal detachment, and 22% with retinal neovascularization. The interventional study showed that minor patients' complaints were reported such as night vision problems, flashes, and peripheral field defects. There was no significant change in the mean preoperative logarithm of the minimum angle of resolution (logMAR) corrected distance visual acuity (CDVA) over time throughout the study (P = 0.951). At the end of follow-up, 89.5% of included eyes showed no loss of any lines of their preoperative logMAR CDVA and 10.5% lost only one line. All eyes remained in the same stage of moderate NPDR with no signs of progression to severe or very severe NPDR or proliferative DR.

Conclusion:

Prophylactic early PRP is an acceptable, safe, and satisfactory procedure for patients with moderate NPDR in low-resource settings.
Comparison of renal artery Doppler parameters of monochorionic diamniotic twin pregnancies with and without twin-to-twin transfusion syndrome
Authors: Zarean Elaheh , Farahbod Farinaz , Khanjani Somayeh , Zanbagh Leila , Tarrahi Mohammad Javad , Veisian Mehrnaz
Published: May 2023

Background:

Monochorionic diamniotic (MCDA) twin pregnancies are considered high-risk for several reasons, especially the risk of twin-to-twin transfusion syndrome (TTTS). Renal artery Doppler (RAD) is reported as a useful tool for predicting oligohydramnios in singleton pregnancies. We aimed to compare the RAD indices between MCDA twins with and without TTTS.

Materials and Methods:

In this case–control study, all pregnant women aged 18–38 years, with gestational age ≥ 18 weeks, who were referred to two Prenatal Clinics, Alzahra and Beheshti Educational Hospitals, affiliated to Isfahan University of Medical Sciences, Isfahan, Iran, October 2020–March 2022 were enrolled; the women with MCDA twin pregnancies complicated by TTTS (case group, n = 12) and without TTTS (control group, n = 24). For each twin, biometric analysis, fetal weight, and Doppler study of fetal arteries, including RAD, middle cerebral artery (MCA), umbilical artery, and ductus venosus were performed. Peak systolic velocity, Pulsatility index (PI), resistance index (RI), and systole/diastole (S/D) were measured for all arteries.

Results:

The donors of the case group had a lower mean MCA S/D (4.48 ± 1.89) than the control group (6.48 ± 1.97) (P = 0.01) and higher mean umbilical parameters, including PI, RI, and S/D (P < 0.05). The recipients of the case group had a lower mean renal PI than the control (P = 0.008) and lower mean MCA PI, RI, and S/D (P < 0.05). The donor group had a higher mean umbilical RI and S/D than the recipient twin, while the mean fetal weight of the recipient group was higher (P < 0.05).

Conclusion:

Comparing the RAD parameters between the twins with and without TTTS in the present study did not identify significant results, which rejected the primary hypothesis. Among all RAD parameters, the only significant difference observed in the present study was the lower RAD PI in RT, which cannot suggest this measurement as a valuable tool for the prediction of TTTS in MCDA twins. Therefore, the results of the present study failed to show the additional value of RAD, compared with the conventional Doppler examination of fetal arteries. Further studies are required to prove this conclusion.

Authors: Duan Xueyu , Liao Binbin , Liu Xiaobo , Chen Ruixiang
Published: May 2023

Background:

Currently, the anticancer effects of metformin on different types of lung cancer have been frequently studied. However, the relationship between metformin and prognosis in nondiabetic patients with lung cancer remains controversial. To systematically evaluate the efficacy of metformin adjunctive therapy as the treatment for nondiabetic patients with advanced non-small cell lung cancer (NSCLC) to provide an evidence-based reference for clinical medication.

Materials and Methods:

The literatures related to Phase II or III randomized controlled trials (RCTs) of metformin adjunctive therapy in nondiabetic patients with advanced NSCLC, including EMBASE, PubMed, the Cochrane Library, and Scopus database, were retrieved by computer, and the search time ranged from January 2017 to August 2022. The risk of bias assessment tool recommended by Cochrane Systematic Evaluator Manual 5.1.0 was used to evaluate the quality of the RCTs included. Rev Man 5.3 software and STATA15.0 were used for meta-analysis.

Results:

A total of 8 studies were included (925 patients). Meta-analysis results showed that there were no significant differences in progression-free survival (PFS) (hazard ratio [HR] = 0.95, 95% confidence interval [CI]: 0.66–1.36, P = 0.77), overall survival (OS) (HR = 0.89, 95% CI: 0.61–1.30, P = 0.55, n =7), objective response rate (ORR) (odds ratio [OR] = 1.37, 95% CI: 0.76-2.46, P = 0.30), and 1-year PFS rate (OR = 0.87, 95% CI: 0.39-1.94, P = 0.73, n = 3). Sensitivity analysis showed that PFS and OS indexes were stable.

Conclusion:

Metformin adjunctive therapy can improve the DCR of nondiabetic patients with advanced NSCLC. In addition, the patients cannot obtain a prolonged PFS, OS, 1-year PFS rate, and higher ORR rate.
Age and tectonic significance of the Benton pluton, Eel River area, west-central New Brunswick, Canada
Authors: Fyffe Leslie R. , Ludman Allan , McFarlane Christopher
Published: May 2023

The Benton pluton, located in the Eel River area of west-central New Brunswick, Canada, consists of two components—the Caldwell Brook quartz monzonite and Dugan Road monzogranite. Field relations suggest that the two are essentially coeval, the Dugan Road being slightly younger. The Benton pluton intrudes Cambrian to Early Ordovician sedimentary rocks of the Woodstock Group and overlying Early to Middle Ordovician calc-alkaline rhyolitic, andesitic, dacitic, and basaltic rocks of the lower Meductic Group. A new U–Pb (LA-ICP-MS) zircon age of 467 ± 2. Ma indicates that the Dugan Road monzogranite component of the Benton pluton was emplaced during the Middle Ordovician (late Dapingian to early Darriwilian). The Dugan Road monzogranite is ca. 7 million years younger than the nearby arc-related Connell Mountain tonalite and Gibson granodiorite, and ca. 13 million years younger than arc- related volcanic rocks of the Porten Road Formation, the oldest unit of the Meductic Group. The Benton pluton is interpreted to have been emplaced in an active extensional arc setting, coinciding with a shift in the focus of subduction-related volcanism from the Eel River area of New Brunswick to the Greenfield area of adjacent Maine, USA.

Работа посвящена исследованию некоторых спектральных свойств оператора Штурма-Лиувилля на полуоси $\mathbb{R}_+$ с растущим на бесконечности комплексным потенциалом. Вместо известных условий В. Б. Лидского об ограниченности снизу вещественной части или полуограниченности мнимой части потенциала предполагается, что область значений потенциала не пересекается с некоторым малым углом, содержащим отрицательную вещественную полуось. При некоторых дополнительных условиях на потенциал типа гладкости и регулярности роста на бесконечности показано, что числовая область оператора заполняет всю комплексную плоскость, спектр дискретен, существует некоторый сектор, свободный от спектра, и любой луч из этого сектора является лучом наилучшего убывания резольвенты. Основываясь на этих фактах, установлена базисность системы корневых векторов для суммирования методом Абеля-Лидского.

Intervention Design of High-Intensity Interval Training in Individuals With Spinal Cord Injury: Narrative Review and Future Perspectives
Authors: Veith Daniel D. , Linde Margaux B. , Wiggins Chad C. , Zhao Kristin D. , Garlanger Kristin L.
Published: May 2023

Background

Individuals with spinal cord injury (SCI) have lower levels of physical activity compared to the nondisabled population. Exercise guidelines recommend moderate or vigorous exercise to improve cardiovascular health and reduce cardiometabolic risk factors in persons with SCI. High-intensity interval training (HIIT) is a popular exercise choice and encompasses brief periods of vigorous exercise paired with intermittent periods of recovery.

Objectives

This review describes the available literature on HIIT for individuals with SCI, including differences in protocol design and suggested areas of further investigation.

Methods

Our institution’s library system performed the comprehensive search. The primary keywords and phrases used to search included spinal cord injury, high-intensity interval training, tetraplegia, paraplegia, and several other related terms.

Results

Initially 62 records were screened, and 36 were deemed outside the scope of this review. Twenty-six studies published between 2001 and 2021 fulfilled the eligibility criteria and were divided among two researchers for review and analysis. All records required persons with SCI and a standardized HIIT intervention. Study design varied widely with respect to mode of exercise, prescribed intensity, duration of performance intervals, and session duration. This variability necessitates further investigation into the specifics of a HIIT prescription and the associated outcomes for persons with SCI.

Conclusion

Standardization of HIIT protocols may lead to more robust conclusions regarding its effects on cardiorespiratory fitness as well as mitigation of cardiometabolic risk factors. Meta-analyses will eventually be needed on proper dosing and session parameters to improve cardiorespiratory fitness and cardiometabolic risk factors.

Published: May 2023

This study aims to predict the movement of Bank Syariah Indonesia shares (BRIS.JK) prices using the Conditional Restricted Boltzmann Machine (CRBM) method. Prediction is needed in conducting share transactions, because the increase or decrease in share price movements is very difficult to predict. The CRBM method is a machine learning algorithm used to model the probability distribution of data associated with variables and inputs. CRBM is a type of Restricted Boltzman Machine (RBM) that consists of two layers, namely the input layer and the hidden layer. CRBM is a type of Boltzmann machine model equipped with a conditioned unit that is used to perform analysis and learning on data that has conditional properties. In this research, the first step is to divide several research scenarios. Then conduct CRBM tests to get prediction results. The data used is daily close data. Based on the research that has been done, it is obtained that the best prediction accuracy is in July - August with MAPE below 5%.

The Tribute of Pope John Paul II to the Holy Brothers Cyril and Methodius: the causes defended by the Holy Father during his pontificate
Authors: Rogozenski Victor
Published: May 2023

Abstract: The purpose of this article is to reveal the respect that Pope John Paul II repeatedly paid to the work of the Holy Brothers Equal to the Apostles – Cyril and Methodius, during his long pontificate. It presents the most important information about the life of Karol Wojtyla before his election as pope in 1978 – birth, childhood, education and his life path as a Catholic priest. The most important issues touched upon in the article are the proclamation of the Thessalonica Brothers as patrons of Europe in 1980, the encyclical dedicated to them issued five years later, the annual meetings of the Pope John Paul II with the Bulgarian delegations on the occasion of 24th May – the day of the sainted brothers Cyril and Methodius and the day of the Bulgarian alphabet, enlightenment and education, and Slavic writing. An important point representing the attitude of the Holy Father towards Bulgaria is the visit to our country organized between May 23rd and 26th, 2002. Thus, the Pope showed his respect for the work of Cyril and Methodius precisely on the Day of Slavic Literature and Culture. It marks the dialogue that John Paul led and the Eastern Orthodox Church during his 27-year pontificate.
The Coin Magistrate ΚΥΡΣΑ and the Cult of Isis, Sarapis and Anubis in Odessos – New Epigraphic and Numismatic Data
Authors: Bekov Vladimir
Published: May 2023

Abstract: The subject of the present article is a newly discovered dedicatory inscription of Isis, Sarapis and Anubis (Обр. 1), made by the society of their venerable believers. Some of these admirers are also connected with the coinage – the coin magistrate ΚΥΡΣΑ was the father of one of the initiates – ΗΡΩΝΥΜΟ. Thanks to the parallel between the epigraphic data and the coins, the newly discovered inscription can be dated to the second half of the 2nd c. BC. From the research it can be concluded that somewhere in the outlines of Odessos during the Hellenistic era, maybe in the sacred territory around the today’s oldest active Christian temple in Varna – “The Assumption of the Holy Virgin” Church, or around the place of the newly discovered inscriptions (18 Tsar Ivan Shishman Str.), existed a temple of Isis, Sarapis and Anubis (№ 4 on Карта 1). Moreover, it is very likely that the upright statue of the Great God of Odessos was erected there in the 3rd–2nd centuries BC, and from its creation to be associated with Pluto/Sarapis, because the statue first appears on the Odessos tetradrachms of their own type (Cat. № 6–7, c. 168–167 BC). The new epigraphic and numismatic data confirm the opinion that the Thracians occupied very important positions in Odessos and perhaps had a leading role from the middle of the 2nd century BC until the capture of the city by Rome.

The Araguaia River is an important Brazilian watercourse that covers several states of the country and has a large extension. It is characterized by a vast aquatic biodiversity, with a variety of habitats that are home to diverse terrestrial and aquatic species. However, the environment faces environmental challenges such as shore degradation, mining, dam construction and overfishing. This study aimed to identify the freshwater bivalves of the Araguaia River, based on specimens deposited in the zoological collection of the Biology Laboratory of the SESI School of Araguaína, State of Tocantins. And so, the results obtained revealed the presence of 13 species of freshwater bivalves, distributed in three families. Such results were possible from the collection of 1071 valves, corresponding to approximately 530 animals. Among the species found, Eupera simoni, Anodontites trapesialis, Lamproscapha ensiformis and Leila esula stand out. However, some valves could not be identified to the specific level due to conservation conditions or lack of pertinent literature.

Understanding how aquatic organisms behave in their natural habitat is an essential activity and one of the techniques that contribute to this understanding is morphometry, which studies the relationship between shape and body growth of fish. With this, this work aims to analyze the morphometric characteristics for two species of fish being, Bryconops giacopinii and Geophagus proximus, in order to support future studies on the dynamics of growth of these species in the Praquiquara river microbasin. The collection of biological material took place between July 2017 and June 2018, from the access to Fazenda Escola de Castanhal - UFRA, using a 2 m throw net with a 1.5cm mesh and gill nets of 15, 25 and 30m in length and 1.6 m high, the caugth fish were identified, measured and weighed in terms of morphometric characters, then the data were processed from a linear regression and the weight-length data were logarithmized to adjust the regression. The data were analyzed using the R software. The results showed that the variables presented correlation that were within the scale of moderate to strong positive (r > 0.50) for both species and that the allometry (b = 3) for the relationships were negative, with the exception of the weight-length relationship of the G. proximus species that presented an isometric growth. Therefore, the microbasin can comprise the feeding area for the studied species, as well as the area of refuge and protection.
