The 100 cited articles in menstrual health among adolescent girls: A Citation analysis
Authors: Alekhya G. , Sahu Dinesh Prasad , Behera Priyamadhaba 
Published: January 2023

Abstract

Background: Menstrual health is a public health concern where it is still considered taboo, and adolescent girls lack knowledge about menstrual health, access to sanitation facilities, and the affordability of sanitary materials. Every year numerous articles are published; however, only a few of them would be influential in the evolution of a particular field. The number of citations received by an article serves as a quality factor for the impact of the article in a particular field. Citation analysis analyses the relationship between citations received by articles. From the literature search, no citation analysis was conducted on menstrual health. Hence the objective of the study was to identify the articles which received a hundred or more citations and also to identify the leading countries, journals, study designs, and departments conducting research on menstrual health.
Methods: Citation analysis was done with search terms pertaining to adolescent and menstrual health using google scholar as a database in Publish or Perish software. The articles retrieved were exported to Microsoft Excel. Articles that received a hundred and more citations were screened for the type of article, department, and country where the study was conducted, and articles that were books, patents, and non-journal publications were excluded. A descriptive analysis of the hundred and more cited articles was done in Microsoft Excel.
Results:A total of 980 articles pertaining to menstrual health among adolescent girls were retrieved. There were a hundred articles with hundred and more citations pertaining to the menstrual health of adolescent girls. There were five citation classics among the hundred articles with hundred and more citations. Cross-sectional study design, Obstetrics and Gynaecology department, India and USA countries, and PLOS ONE journal, had the most citations in research on menstrual health among adolescent girls. The top ten articles were on menorrhagia, menstrual hygiene practices, Water, Sanitation and hygiene (WASH), stigma on menstruation, and education on menstrual health.
Conclusion: The present citation analysis analyses the top countries, journals, and departments conducting research on menstrual health, and there is an immediate need to strengthen research in lower-income countries and conduct more interventional studies.

Published: January 2023

Abstract
Background: Daily or near-daily cannabis users vary considerably in their daily dosage and use frequency, impacting both experienced effects and adverse consequences. This study identified heavy cannabis user groups according to consumption patterns and factors associated with class membership.
Methods: We conducted a cross-sectional survey of 400 Spanish residents (62.2% male; average age=29.6 years) who had used cannabis ≥3 days/week throughout the past year. Participants were recruited through chain referral and cannabis social clubs. We applied latent class analysis (LCA) to cluster participants according to use intensity. Associations between class membership and socio-demographics, use patterns, motives, supply sources, adverse outcomes, and use of other substances were measured using ANOVA and chi-squared tests. Multinomial regression identified the factors associated with latent class membership.
Results: Three latent classes (moderately heavy: 23%, heavy: 67.5%, very heavy: 9.5%) had average weekly cannabis intakes of 2.3, 5.6, and 18.3 grams, respectively. Age, education, years of use, buying cannabis in a club, Cannabis Abuse Screening Test (CAST) scores, and cocaine use were associated with cannabis use intensity. Very heavy users were older ( X2 =20.44, p<0.01), less educated X2=28.92, p<0.001), and had used cannabis for longer (F=6.80, p=0.001). The prevalence of past-month cocaine use ( X2 =13.90, p<0.05) and CAST scores (F=25.73, p<0.001) increased across the classes. Cannabis was usually obtained from a club by very heavy users ( X2 =24.40, p<0.001).
Conclusions: Heavy cannabis users are heterogenous and present several groups according to frequency and quantity of cannabis consumption. Use intensity is associated with increased cannabis use disorders and dependence.

Authors: Abdulwahid Maan Muataz , KURNAZ Sefer 
Published: January 2023

Abstract
This study proposes a Multiple Input Multiple Output (MIMO) antenna array with three orientations for the transmitter device, as well as a 2-Ray Model for dealing with communications in an outdoor scenario. This orientation would be referred to as the (Horizontal, Vertical and Planar). Line of Sight (LoS) rays and ground-based reflected rays between the Tx and Rx have been incorporated in the proposed 2-Ray model. The research was carried out by using the most relevant software for route propagation-based ray tracing (Wireless InSite software) with the latest version in 2023. Different factors and Tx heights were examined when examining the findings for our study. The affects seen in the three examples were caused by the effects of varied antenna polarization, directivity, and diversity methods. Results obtained can confirm the reliable and optimum MIMO point placement as an array that can achieve the best overall transmission with less losses.

Published: January 2023

Abstract
Selective laser melting (SLM) is a prevalent additive manufacturing (AM) technique for the fabrication of metallic components. A modified GTN (Gurson-Tvergaard-Needleman) model was developed, based on the understanding of the SLM process and SLM-manufactured parts, in order to characterize void growth and void shear mechanism to predict the ductile fracture behavior of SLM-fabricated Ti6Al4V alloys under uniaxial stress states. The effect of the number of hidden layers and neurons, as a basic parameter of an artificial neural network (ANN), on predicting parameter relation accuracy was investigated. In this study resulted due to the complex relation among GTN fracture parameters and fracture displacement, defining more hidden layers in ANN improves the accuracy of predicting the damage and fracture behavior of SLM-fabricated Ti6Al4V alloys under uniaxial stress states; however, forecasting maximum force is achieved accurately by fewer hidden layers in comparison with fracture displacement needing to higher layers to predict precisely. Furthermore, the system R 2 -value reaches higher accuracy more than 0.99 for both maximum force and fracture displacement based on selected hidden layers and neurons.

Published: January 2023

Im Rheinland fallen zwei frühblühende Capsella-Sippen auf. Die zuerst blühende Sippe, Capsella I genannt, würde man als Teil einer weit gefassten C. bursa-pastoris ansehen. Etwas später blüht C. rubella, eine bisher vermutlich weitgehend übersehene Art des Rheinlandes. Taxonomie und Merkmalsbewertung bei Capsella werden diskutiert.
Mitteldeutschland endemische Unterart des Bromus secalinus (Poaceae)
Authors: Scholz Hildemar , Thiel Hjalmar 
Published: January 2023

Bromus secalinus, früher sehr häufig in Getreidefeldern, aber im letzten Jahrhundert durch Bekämpfungsmaßnahmen immer seltener geworden, ist derzeit mit geänderter Landbaupraxis wieder in Ausbreitung begriffen und umfasst heute zwei morphologisch definierte Unterarten. B. secalinus subsp. infestus wird als neu für die Wissenschaft beschrieben und ist vermutlich ein Neo-Endemit der Flora Mitteldeutschlands. Seine Herkunft und Evolution wird diskutiert (a) nach der neodarwinistischen Selektionstheorie und (b) nach der neogoldschmidtschen Saltationstheorie.
Erstnachweis von Dryopteris affinis s. str. (Dryopteridaceae, Pteridophyta) für Nordrhein-Westfalen
Authors: Bennert Herbert Wilfried , Neikes Norbert , Gausmann Peter , Jäger Wolfgang , Lubienski Marcus , Viane Ronald 
Published: January 2023

Neuerdings werden fünf Sippen des Dryopteris-affinis-Komplexes in Mitteleuropa als eigenständige Arten bewertet, wovon vier auch in Nordrhein-Westfalen (NRW) vorkommen. Dazu gehören die triploide D. bor­reri, die offenbar die mit Abstand häufigste Art repräsentiert, und zwei weitere triploide Arten, D. pseudodisjuncta und D. lacunosa. Letztere wurde erst vor kurzem neu beschrieben und ist in NRW bislang nur von einem Fundpunkt bekannt. Mit Hilfe der Flow-Cytometrie gelang es nun, eine auf Grund der kleinen Sporen verdächtig erscheinende Pflanze aus dem Schwalm-Nette-Gebiet als diploide D. affinis s. str. zu identifizieren. Die anfängliche Vermutung, diese Art sei auf Tiefland-Vorkommen im deutlich atlantisch getönten äußersten Nordwesten von NRW beschränkt, haben sich als unzutreffend erwiesen; die Art konnte nachfolgend auch mehrfach im Süderbergland gefunden werden. Ebenfalls mit Hilfe der Flow-Cytometrie wurden eine Reihe von Vorkommen von D. borreri bestätigt sowie tetra- und pentaploide Hybriden (D. ×complexa und D. ×critica) nachgewiesen, die durch Bastardbildung mit D. filix-mas entstehen. Während Vorkommen der pentaploiden D. ×critica bereits seit längerer Zeit aus NRW bekannt sind, handelt es sich bei denjenigen von D. ×complexa ebenfalls um Erstnachweise. Das nordrhein-westfälische Areal dieser Sippen wird in drei Fundortkarten dargestellt (für den D.-affinis-Komplex insgesamt sowie für cytologisch bzw. flow-cytometrisch bestätigte Vorkommen der beiden Arten D. affinis s. str. und D. borreri sowie der beiden Hybriden D. ×complexa und D. ×critica). Aus einer mit der räumlichen Verteilung der Jahresniederschläge kombinierten Verbreitungskarte wird die enge Bindung an niederschlagreichere Lagen (zumeist mehr als 800 mm) deutlich. Dies und weitere standortökologische Besonderheiten weisen darauf hin, dass die Sippen des D.-affinis-Komplexes in größerem Maße von der Wasserversorgung abhängig sind als D. filix-mas. Zwar repräsentieren die D.-affinis-Sippen offenbar typische Waldfarne und zeigen eine Präferenz für bodensaure Buchenwald-Gesellschaften, vor allem D. affinis s. str. kommt aber auffallend häufig an anthropogen überformten Sekundärstandorten vor, so an Weg- und Grabenböschungen, in Abgrabungen sowie an einem künstlichen Steilhang und in einem Steinbruch.
Festuca tomanii sp. nov., ein Dünen-Schwingel des nördlichen Oberrhein-, des mittleren Main- und des böhmischen Elbetal
Authors: Korneck Dieter , Gregor Thomas 
Published: January 2023

Auf basenreichen Sanden des nördlichen Oberrhein-, mittleren Main- und böhmischen Elbetales wachsende, blaugrün bereifte tetraploide Schwingel, die bisher meist als Festuca duvalii angesprochen wurden, werden als F. tomanii neu beschrieben. von F. duvalii unterscheidet sich F. tomanii durch (1) pergamentartige Scheiden der Grundblätter, von denen die Spreiten frühzeitig abfallen (F. duvalii: Scheiden der Grundblätter nicht pergamentartig, Spreiten lange erhalten bleibend), (2) dickere Blätter (0,8–1,1 mm vs. 0,6–0,9 mm) mit mehr Leitbündeln (9–11 vs. 7) sowie (3) durch einen ± geschlossenen Sklerenchymring (F. duvalii: Sklerenchym überwiegend in drei Bündeln). Die Bestände von F. tomanii sind stark rückläufig; die meisten Populationen finden sich an Reliktstandorten. F. tomanii ist ein typischer Bestandteil des Jurineo cyanoidis-Koelerietum glaucae (Koelerion glaucae).
Stellaria-media-Gruppe in Mitteleuropa – Chromosomenzählungen und Anmerkungen zu den Differentialmerkmalen
Authors: Hügin Gerold , Dersch Gunther , Gregor Thomas 
Published: January 2023

Aus der Stellaria-media-Gruppe wurden Chromosomenzahlen aus Mitteleuropa (Deutschland, Frankreich, Schweiz) ermittelt: S. apetala (2n = 22), S. media (2n = 40, 2n = 80), S. neglecta (2n = 22). Ergänzend erfolgte eine flowzytometrische Untersuchung. Wegen großer genetischer und standörtlicher Variabilität der S. media kann vor allem die Unterscheidung von S. neglecta schwierig sein. Bei der Bestimmung ist immer auf den gesamten Merkmalskomplex zu achten, insbesondere auf Samengröße und Staubblattanzahl. Näher eingegangen wird auf das meist überbewertete Merkmal "Samenhöcker" und das bisher nur wenig beachtete Merkmal "Samenmasse" (Hundertkornmasse).

Authors: Patel Priyank , Mehta Darshan , Sharma Neeraj 
Published: January 2023

Abstract
There are different sources of groundwater pollution among them industrial water disposal, seawater ingress, usage of pesticides and fertilizers in agricultural fields, and municipal and residential wastewater disposal. The aim of the study is to assess groundwater vulnerability in terms of quality using the GOD method using the Geographical Investigation System approach for Surat and its surroundings. Groundwater confinement, overlying strata and depth to water table are the three parameters that are used in the assessment of groundwater vulnerability. In this study, all three parameters are given by the conventional weights which are suggested by Foster 1987. Based on the study Mahuva, Mandvi, Umarpada and some parts of the Bardoli talukas lie in very high-vulnerability zones whereas another part of the study area lies in a high-vulnerability zone. Almost 35.98% of the area of the district lies in the higher-vulnerability zone. Depth to the water table and the overlying strata are very important parameters that effectively cause groundwater vulnerability. This study may help in groundwater quality management, and watershed management as well as it is very much useful for the policymakers and local authorities as well as the government.

Published: January 2023

Abstract:
Cancer is still one of the most serious diseases that threaten human life. In the past decades,
nanomaterials have been found to possess excellent advantages, including controlled drug release, easy
modification surface, good biocompatibility, typical optical property, useful chemical ability, and so
on, due to which they have become the rising star in the application for multimodal combined cancer
treatment (MCT). The emerging avenues of photodynamic therapy, photothermal therapy, magnetocaloric
therapy, chemodynamic therapy, immunotherapy, and gene therapy are integrated systematically
and intelligently with the traditional methods, realizing the therapeutic effect in cancer treatment.
However, there are still several challenges in the development of nanomaterials for MCT, such as the
construction of complex systems, deep penetration into solid tumors, effective immune activation at
tumor sites, and so on. This review describes the application of multifunctional nanomaterials in the
field of MCT for tumor, proposing some suggestions and ideas for future development.

Published: January 2023

Abstract:
In the field of Chemistry, it is essential to study molecules with biological activity on chronic
degenerative diseases to design drugs that help to improve the health of people with diseases such as
diabetes, arterial hypertension, rheumatoid arthritis, cancer, among others; and that in turn may have
fewer side effects. Diabetes mellitus is a serious metabolic disorder that affects millions of people
worldwide; due to the illness severe affectations, there is a great interest in improving pharmacological
treatments (hypoglycemic drugs) used in this disease. Nowadays, it has been reported that metallodrugs
and drug-cyclodextrin inclusion compounds have higher therapeutic activity than free drugs,
with fewer side effects. In the present work, we compile, analyze, synthesize and discuss published
information on the hypoglycemic drugs Metformin (C4H11N5), Chlorpropamide (C10H13ClN2O3S) and
Glibenclamide (C23H28ClN3O5S) complexed with metal ions or included in cyclodextrins in aqueous
solution. Nowadays, this type of complex should be widely studied for the treatment of type 2 diabetes
mellitus. Physicochemical and thermodynamic properties, synthesis, mechanism of action, as well as
analytical studies on the interaction of hypoglycemic agents with different complexing agents, are discussed.

Authors: Torres-Herrera Carlos , Silva-Tetlak Mario , Zarate-Vidal Leonardo , Burrows-Rojo Darwig , Vega-Zambrano María Isabel , Gutierrez-Arias Ruvistay 
Published: January 2023

Background:
Heart rate variability (HRV) analysis is a relevant indicator of autonomic nervous system function over the cardiovascular system. The usual way to measure this variability is from the electrocardiogram (ECG).

Objective:
To assess the validity of HRV measurements obtained from a heart rate monitor (HRM) Polar® V800 in critically ill adult subjects.

Materials and Methods:
A prospective, repeated measures, observational study was conducted in two in the Chilean intensive care units. Twenty-one different HRV variables were simultaneously assessed using a Polar® V800 HRM and an ECG Mortara® H3 Holter device. The data was collect-ed from the clinical record and physical examinations. The evaluations were conducted for 10 minutes at a time and simultaneously, during which the subjects had to remain supine and at rest. The sampling frequency was 1000 Hz, providing a temporal resolution of 1 millisecond for each RR period.

Results:
Thirty adult subjects were included with an average age of 33.63 ± 8.91 years. When com-paring both HRV assessment methods, only 3 variables showed statistically significant differences (p ≤ 0.05). As well, the correlations showed 4 strong and 17 near-perfect associations, which were positive and statistically significant (p ≤ 0.001). In addition, intraclass correlation coefficients (be-tween 0.744 and 1) and bias determined using the Bland-Altman method found both methods to be concordant.

Conclusions:
The Polar® V800 monitor is a valid tool for assessing HRV in critically ill adult sub-jects.

amide Compounds
Authors: Huang Yanmin , Peng Zining , Liu Chang , Pang Chunling , Chen Sijing , Gan Chunfang , Liu Zhiping , Cui Jianguo 
Published: January 2023

Background:
The structure modification of steroids is commonly used to change the biological
activity of steroids in medicinal chemistry. In recent years, it has been found that some derivatives
derived from the structural modification of cholesterol display good inhibitory activity against
tumor cell proliferation in vitro.

Methods:
Using cholesterol as the starting material, different types of B-norcholesterol-6-amide
derivatives were synthesized by the reaction of 6-carboxyl-B-norcholesterol with different alkyl
amines or 6-amino-B-norcholesterol with different acyl chlorides. The inhibitory activity of compounds
on the proliferation of tumor cell lines was investigated by the MTT method.

Results:
The results showed that the B-norcholesterol-6-amide compounds displayed distinct cytotoxicity
against Sk-Ov-3 cells but caused no obvious damage against HEK-293T cells. Additionally,
the steroidal amide derivatives formed from 6-amino-B-norcholesterol showed stronger cytotoxicity
than those produced from 6-carboxyl-B-norcholesterol. Specially, compounds with chloroalkyl structure
displayed significant inhibitory activity against all tumor cells tested. Among them, compounds
19-21 showed cytotoxicity like 2-methoxyestradiol as a positive control, and the IC50 value of compound
20 on HeLa cells was 3.9 μM.

Conclusion:
After introducing chloroalkyl acyl groups into 6-position of 6-amino-B-norcholesterol,
the cytotoxicity of resulting B-norcholesterol-6-amide compounds can be greatly enhanced.

Authors: Amthaghri Smail , Amssayef Ayoub , Slaoui Miloudia , Eddouks Mohamed 
Published: January 2023

Aims:
The study aimed to investigate the effect of Euphorbia cheiradenia on blood
pressure.

Background:
Euphorbia cheiradenia is a medicinal plant with several medicinal properties.

Objective:
This study aimed to study the vasorelaxant and antihypertensive capacity of the aqueous
extract of Euphorbia cheiradenia (E. cheiradenia), and to evaluate its effect on angiotensinconverting
enzyme 2 (ACE2).

Methods:
The antihypertensive ability of aerial parts of the aqueous extract of E. cheiradenia
(AEEC) was investigated in L-NAME-induced hypertensive rats, and its vasorelaxant effect was
performed on the isolated thoracic rat aorta. In addition, the possible inhibitory effect of AEEC on
ACE2 was also studied.

Results:
AEEC lowered blood pressure parameters in hypertensive rats. The study of the vasorelaxant
activity revealed that AEEC partially relaxed the aortic rings through activation of the
KATP channel and inhibition of the β-adrenergic pathway. Whereas pretreatment of aortic rings
with nifedipine, indomethacin, L-NAME, and methylene blue did not attenuate AEEC-induced
vasorelaxation. However, AEEC did not affect ACE2 in isolated rat aortas.

Conclusion:
The study showed that aqueous E. cheiradenia extract exhibits significant antihypertensive
activity in hypertensive rats.
