Carbonaceous Catalyst Activated Persulfate for Degradation of Antibiotic Pollutants in Water
Authors: Zhong Chen Kai
Published: March 2023

In recent years, the frequent use of antibiotics has led to the continuous release of antibiotics into the water environment, which not only poses a potential threat to public health, but also contributes to the generation and spread of antibiotic resistance. In addition, due to the high environmental persistence and low biodegradability of antibiotics, it is difficult to be effectively degraded by traditional water treatment processes. Therefore, it is urgent to develop clean and efficient treatment technologies. Advanced oxidation processes (AOPs), which can effectively remove refractory organic pollutants from water, has become a promising water treatment technology. In this regard, persulfate (PS)-based AOPs (PS-AOPs) has attracted extensive attention of researchers. In this system, PS can be activated by energy and catalysts to produce highly oxidizing active species, and achieve efficient degradation of antibiotics. Due to its rich surface functional groups, high specific surface area and high adsorption properties, researches on the activation of PS by carbonaceous materials have been reported continuously. In this paper, the research progress of carbon nanotubes, graphene, biological carbon, active carbon and hetero-atom doped carbon materials as catalysts to activate PS and degrade antibiotics is reviewed. In addition, the structure and properties of different carbon materials and the activation mechanism of free radical and non-free radical mediated by carbon materials were introduced, and the effects of PS dosage, catalyst dosage, temperature and pH on the degradation of antibiotics were discussed. Finally, this paper points out the important development direction in the future, that is, the development of environmental protection, high efficiency, low cost carbon materials and further research on the actual wastewater treatment performance.

Authors: Fadehan Gabriel , Olasoji Yekeen O. , Adedeji Kazeem Bolade
Published: March 2023

In this paper, a microstrip line-fed rectangular-shaped ultra-wideband (UWB) antenna offering triple-band notch characteristics is proposed. The notching was done primarily to provide rejection for Wi-Max (3.3-3.7 GHz), WLAN2 (5.15-5.825 GHz), and ITU (8.025-8.4 GHz) through the combination of slots and a modified electromagnetic band gap (M-EBG). The antenna was simulated using HFSS and CST modelling tools. The antenna was able to notch three frequencies from narrow band communication systems (Wi-Max, WLAN2, and ITU), causing interference within the UWB band. The gain of the system over the operating frequency, the current distributions, and the impedance covered were studied to assess the effectiveness of the antenna. The proposed antenna is simple and compact, with a total antenna size of 19 mm by 24 mm and a wide bandwidth (3.2 to 12.5 GHz). Satisfactory results have been obtained when its performance was analyzed. A stable radiation characteristic is observed with a radiation efficiency of 94% when operating at a UWB resonant frequency of 6.85 GHz with a total gain between -10 dB and 5 dB within the range of the frequency band of 3.2 to 12.3 GHz.

Authors: Karuna Agrawal , Lata Shahani , Pradeep Bhatnagar
Published: March 2023

Objective:

To investigate the protective role of pumpkin seed ethanolic extract against escitalopram-induced reproductive toxicity in male mice.

Methods:

Swiss albino male mice were randomly divided into five groups with six mice in each group. Group I received normal water orally, Group II, III, IV and V received escitalopram oxalate (10 mg/kg), pumpkin seed extract (300 mg/kg) plus escitalopram oxalate (10 mg/kg), escitalopram oxalate (20 mg/kg), and pumpkin seed extract (300 mg/kg) plus escitalopram oxalate (20 mg/kg), respectively. All test doses were continuously administered orally once daily per animal body weight for 30 days and 60 days. Body weight and sexual organ weight were evaluated on day 31 and 61. Effects of pumpkin seed extract on sperm parameters, biochemical parameters and histology of testis were also investigated.

Results:

Escitalopram 10 or 20 mg/kg caused reproductive toxicity in male mice after 30 and 60 days of treatment. However, simultaneous administration of escitalopram oxalate (10 or 20 mg/kg) with pumpkin seed extract (300 mg/kg) attenuated escitalopram-induced testicular toxicity. Significant increase in the body weight and relative organ weight was observed. Sperm count, sperm motility and viability significantly increased (P<0.05). The histopathological alterations caused by escitalopram was also ameliorated.

Conclusions:

Ethanolic extract of pumpkin seeds (300 mg/kg body weight) protects again reproductive toxicity induced by escitalopram. Therefore, dietary intake of pumpkin seed extract might be useful for male patients who expose to antidepressant drug due to depression.

Authors: Rezaee Delsuz , Bandehpour Mojgan , Kazemi Bahram , Bastaminejad Saiyad , Najafi Sajad , Salehi Mohammad
Published: March 2023

Objective:

To compare the effect of human chorionic gonadotropin (hCG)-producing peripheral blood mononuclear cells (PBMCs) and PBMCs activated by hCG in vitro and expressions of related immune genes in mouse implantation.

Methods:

hCG-producing PBMCs (transfected PBMC) and PBMCs activated by hCG in vitro were introduced into isolated mouse endometrial cells, while cell cultures were divided into four groups: the control, PBMC, transfected, and activated PBMC groups. The expression of studied genes (IL-lβ, IL-6, Lif, and Vegf) was evaluated and blastocyst attachment on the cocultured cells (isolated endometrial cells and PBMC cells) was monitored in all four groups.

Results:

Data showed that expression decreased in the PBMC group compared to the treated PBMC (transfected and activated PBMCs) and increased in transfected PBMC compared to the activated PBMC. Attachment and migration of blastocysts were dramatically enhanced in the transfected PBMC group compared to the activated PBMC group (P<0.05).

Conclusions:

Use of hCG-producing PBMCs (transfected PBMC) has more influence on endometrial receptivity.

Published: March 2023

Introduction:

The problem of infertility is experienced as a crisis or major life stressor with potentially serious negative effects on the couple’s relationship and preparation toward the parenthood. According to Sharlip et
al., it has been estimated that about 15% of couple would have trouble in conception, and at present, 48.5 million couples experience infertility globally. To decrease the stress among parents to be and to promote healthy parenting for bringing out healthy parent–child relationships, an intervention of Parent Education Program was planned and executed. A study was conducted with the aim to assess the effectiveness of parental preparedness package (PPP) on physical health among couple conceived with artificial reproductive techniques (ART).

Materials and Methods:

The study was conducted to evaluate the effectiveness of PPP in fifty couples conceived with ART at Dayanand Medical College and Hospital, Ludhiana. Quantitative approach was used to collect the data of couples by doing pre- and postinterventional assessment of physical health of couple using the Structured Physical Health Assessment Scale. Analysis was done with the help of descriptive and inferential statistics.

Results:

The study revealed that mean score of physical health of couple (both husband and wife) increased significantly after the intervention which infers the effectiveness of PPP (P = 0.001).

Conclusion:

Our study concludes that PPP should be incorporated in the antenatal care protocol in all couples who conceive using ART.

Published: March 2023

Context:

Laparoscopic cholecystectomy (LC) is established as the gold standard for benign gallbladder disease. This study was done for the evaluation of preoperative scoring system given by Randhawa and Pujahari considering various preoperative parameters to predict difficulty in LC.

Aims:

Preoperative prediction of difficult LC using a scoring system considering various preoperative factors in elective/interval LC to predict difficult gallbladder.

Settings and Design:

A prospective study of 120 patients admitted for LC from January 2020 to June 2021 was analyzed.

Subjects and Methods:

All the patients were evaluated on the basis of Randhawa and Pujahari scoring system with the following variables: age >50 years, male sex, body mass index 25.1–27.5 and >27.5 kg/m2, previous abdominal surgery, prior hospitalization for gallstone disease, palpable gallbladder, gallbladder wall thickening, impacted stone, and pericholecystic collection. Each variable had given a score. Based on these findings, the surgical procedure was defined as easy, difficult, and very difficult.

Results:

One hundred and twenty cases satisfying the inclusion criteria were studied comparing different variables and assigned preoperative scoring. A score >5 was considered significant and compared with intraoperative findings. Out of 53 patients having preoperative scores >5, 40 were difficult gallbladders and 13 were easy to operate. Prediction came true in 93.0% of difficult cases and 83.1% of easy cases.

Conclusions:

From this study, we can conclude that the preoperative scoring system is statistically reliable to predict difficulty in LC in the majority of the cases (area under receiver operator characteristics = 0.935).

Authors: Agarwal Sandhita , Agarwal Sonahita
Published: March 2023

Purpose:

The assessment of bone age has applications in a wide variety of fields: from orthodontics to immigration. The traditional non-automated methods are time-consuming and subject to inter- and intra-observer variability. This is the first study of its kind done on the Indian population. In this study, we analyse different pre-processing techniques and architectures to determine the degree of maturation (i.e. cervical vertebral maturation [CVM]) from cephalometric radiographs using machine learning algorithms.

Methods:

Cephalometric radiographs—labelled with the correct CVM stage using Baccetti et al. method—from 383 individuals aged between 10 and 36 years were used in the study. Data expansion and in-place data augmentation were used to handle high data imbalances. Different pre-processing techniques like Sobel filters and canny edge detectors were employed. Several deep learning convolutional neural network (CNN) architectures along with numerous pre-trained models like ResNet-50 and VGG-19 were analysed for their efficacy on the dataset.

Results:

Models with 6 and 8 convolutional layers trained on 64 × 64–size grayscale images trained the fastest and achieved the highest accuracy of 94%. Pre-trained ResNet-50 with the first 49 layers frozen and VGG-19 with 10 layers frozen to training had remarkable performances on the dataset with accuracies of 91% and 89%, respectively.

Conclusions:

Custom deep CNN models with 6–8 layers on 64 × 64–sized greyscale images were successfully used to achieve high accuracies to classify the majority classes. This study is a launchpad in the development of an automated method for bone age assessment from lateral cephalograms for clinical purposes.

Authors: Patil Nishant B , Bhat Sushma N , Christopher Janisha J , Abhane Rameshwari V , Bagal Uttam R , Nagare Gajanan D
Published: March 2023

Recording of peripheral pulse serves as a very important and essential non-invasive tool used widely by doctors for the diagnosis of various diseases. The morphology of pulse is seen to vary as a function of time in a given individual and also from individual to individual. There are many variations in morphological patterns of peripheral pulse in different disease conditions, which lead to difficulty in accurate diagnosis. The peripheral pulse waveforms are extracted from radial arteries as time series data using a peripheral pulse analyzer which is designed on the principle of impedance plethysmography. It was first introduced by Nyober in the mid-nineteen hundreds and ameliorated further by Kubicek. It involves the recording of the instantaneous blood volume by the measurement of electrical impedance as a function of time. Therefore, the study of peripheral pulse morphology has gained much attention in the past few years among researchers. Physiological variability is one of the recent investigations added during the last two decades for the objective assessment of autonomic function and the assessment of prognosis in severe sicknesses namely myocardial infarction, diabetic neuropathy, etc. In addition to heart rate variability studied worldwide, few researchers have studied blood pressure variability and peripheral blood flow variability. In this computer era, artificial intelligence and machine learning techniques have become more important day-by-day, and different types of algorithms were used for the identification of hidden patterns from plethysmographic observations on the radial pulse such as support vector machine as well as crisp and fuzzy clustering. Eight patterns were classified with a yield of 80%–90% and helped with the diagnosis of disorders such as myocardial infarction, pulmonary tuberculosis, coronary artery disorders, cirrhosis of the liver, and bronchial asthma. This paper briefly describes the use of machine learning techniques for the classification of peripheral pulse morphologies.

Authors: Diengdoh Ibanlumlin , Ali Arif
Published: March 2023

Backgrounds:

College years are characterized by transitioning from pre-adult to adulthood, a period of turmoil, adjusting to the new condition, separation from parental supervision, independence, and countering new things throughout everyday life. Depression and health-risk behaviors, including alcohol, tobacco, and illicit drug, are often found in college students, particularly during their first year.

Aim:

To study the prevalence and predictors of depression among college-going youth of Meghalaya, India.

Materials and Methods:

A cross-sectional community-based study has been undertaken to find the prevalence of depression, alcohol use, and drug use in college-going youth in Shillong, Meghalaya. A random sampling technique was used for the selection of colleges, and total enumeration was used for the selection of college-going students. A total of 358 respondents were selected for the present study. Permission from the college authority was obtained, and written informed consent was taken from the students. The participants have been explained the purpose of the study and the samples were selected voluntarily. The present study’s data were analyzed and interpreted using Statistical Package for Social Sciences version 20.0. Socio-demographic datasheet, Beck Depression Inventory-II, Hamilton Anxiety Rating Scale, Alcohol Use Disorder Identification Test, and drug abuse screening test were administered.

Results:

In the present study, 40.5% fall under the normal range of depression, while 38.3% had mild mood disturbance, 10.3% had borderline clinical depression, 9.7% had moderate depression, and severe depression was found in 1.1%. Alcohol use, drug use, and gender contribute significantly to the prediction of depression among college-going students (F[5,19.551] = 855.3, P = 0.000) accounting for 21.7% variance.

Conclusion:

Our findings highlight the need for a college mental health program for early identification and screening of substance use and depression in college students.
Dyslipidemia as a risk factor for acute myocardial infarction in postmenopausal women: An observational study
Authors: Som Pradipta , Seth Bikas C , Acharyya Malay
Published: March 2023

Objective:

This study has evaluated risk factors, especially dyslipidemia, for an acute myocardial infarction (AMI) in postmenopausal women.

Materials and Methods:

This was a hospital-based, observational, single-center study among 100 postmenopausal women admitted to the medicine ward with AMI. They were categorized based on lipid profile groups, viz., dyslipidemic group and non-dyslipidemic group. All clinical parameters were studied between the groups.

Results:

Among anthropometric profiles, in the comparison of mean height (cm), weight (kg), body mass index (BMI) (kg/m2), and waist circumference (WC) (cm) for the dyslipidemic group and non-dyslipidemic group, only WC was statistically significant (P < 0.001). Most patients were hospitalized between 6 and 12 h after the onset of symptoms. At the time of hospitalization, most patients from both groups were observed to have diabetes and hypertension with poor control of postprandial blood sugar, glycated hemoglobin, and diastolic blood pressure (DBP) (P < 0.05). The dyslipidemic group’s mean C-reactive protein was higher (P < 0.05). The comparison of mean total cholesterol, triglyceride (TG), low density lipoprotein-cholesterol in mg/dL, and TG: high density lipoprotein was significantly increased (P < 0.001), while high density lipoprotein-cholesterol (mg/dL) was significantly decreased (P < 0.001) in the dyslipidemic group. ST-segment elevation myocardial infarction is standard in both groups. The maximum patient has regional wall motion abnormality in echocardiography after day 3 of admission. Among the dyslipidemic group, ejection fraction was on the lower side, and the predominant complication was in the left ventricular failure (LVF) (P < 0.05).

Conclusion:

WC has a positive association with patients with AMI who have dyslipidemia and can be used as an indicator of the risk of AMI when BMI is normal. WC is a surrogate marker of abdominal fat mass (subcutaneous and intra-abdominal); increased WC is a significant component marker of metabolic syndrome and insulin resistance related to cardiovascular mortality. There was poor glycemic control and blood pressure (mainly DBP) among the dyslipidemic patients. Hypertriglyceridemia is the most common lipid abnormality, followed by hypercholesterolemia among the dyslipidemic group. LVF is the most common complication in dyslipidemic patients.

Objective:

Otomycosis is a common fungal ear infection in tropical and subtropical regions worldwide. This study aimed to perform mycological analysis on fungal debris from the external auditory canals of the patients to study the most common clinical presentation and fungal species distribution in otomycosis.

Materials and Methods:

Patients who met the inclusion criteria for this cross-sectional study were included and evaluated after providing written informed consent. After obtaining a thorough medical history, ear swabs for culture, sensitivity, and potassium hydroxide were provided. Patients with positive culture results were studied between September 2019 and March 2021.

Results:

Among 103 cases observed for 18 months in the Department of ENT, Rajarajeswari Medical College, and Hospital, Bengaluru, India, we found that males (56.31%) were more affected than females (43.68%). Itching (67.96%) was the most primary and common symptom that was observed, followed by pain (20.38%), and the most common predisposing factor was the usage of earbuds (26.21%) followed by water in the ear (23.3%) and oil in the ear (16.50%). Unilateral infection was most common (96%), and the left ear was most affected (64.07%). Aspergillus niger was the most common fungal isolate (60.19%), and otomycosis was very common in postmonsoon (October–December) (58.25%).

Conclusion:

The most frequent fungal isolates in otomycosis are from the Aspergillus and Candida species. The left ear was typically affected by otomycosis, which frequently had a unilateral predominance. The most common clinical symptoms were itching and pain.

Authors: Sinha Soni , Raj Nikhil , Dobhal Shipra , Das Anupam , Agarwal Jyotsna
Published: March 2023

Background:

Achromobacter spp. is a rare nosocomial pathogen known to cause many serious infections like bloodstream infection, osteomyelitis, meningitis, urinary tract infections, corneal ulceration, peritonitis, and endocarditis.

Materials and Methods:

In this study, we retrospectively analyzed all the bacteriological sample records from the bacteriology database from January 2021 to December 2021 to determine the prevalence of Achromobacter spp.

Result:

Nine patients with Achromobacter xylosoxidans causing bacterial infection were identified, from whom five blood samples, two pus, one respiratory sample, one central venous pressure (CVP), and one cerebrospinal fluid were found positive for Achromobacter spp., among whom one was a 6-year-old patient having the same organism from two different body sites—CVP line and cerebrospinal fluid. Five patients had coinfection with another organism, whereas acute kidney injury was the most common comorbidity.

Conclusion:

In our single-center experience, approximately 50% of the cases with Achromobacter denitrificans bacteremia suffered from chronic kidney disease and had a history of antibiotic therapy, hospitalization, and the presence of devices. Active research on rising trends of Achromobacter spp. needs to be promoted.
A Qualitative Study of the Knowledge, Experiences, Perceived Roles, Cultural Barriers, and Skills of Community Pharmacists Dealing with Saudi Patients with Asthma
Authors: Alzayer Reem
Published: March 2023

Background:

In Saudi Arabia, asthma is one of the most common chronic respiratory diseases. Previous studies have identified that asthma management can be influenced by patients’ cultural beliefs and levels of asthma education. Therefore, community pharmacists should have good knowledge of both asthma and Saudi cultural beliefs to be able to effectively educate Saudi patients.

Objective:

The purpose of this study was to explore Saudi community pharmacists’ knowledge, experiences, and perspectives on providing care for Saudi patients with asthma.

Materials and Methods:

A qualitative method was employed to conduct semistructured interviews in the Eastern Province of Saudi Arabia. Community pharmacists were interviewed on the phone using an interview guide, and participants were recruited purposively. Verbatim transcripts of interviews were then thematically analyzed.

Results:

Analysis of 22 interviews resulted in five emergent themes: (1) lack of asthma knowledge among community pharmacists; (2) cultural and religious issues; (3) counseling issues; (4) patient medication issues and navigating the healthcare system; and (5) the need for asthma recourse and training. The findings indicate that community pharmacists have unsatisfactory levels of asthma knowledge and lack access to asthma guidelines in Saudi Arabia. It was also evident that the asthma management of Saudi patients was influenced by patients’ cultural and religious beliefs, which pharmacists needed to consider during patient counseling.

Conclusions:

Due to the lack of knowledge about asthma among our participants, there is an urgent need for asthma training. Furthermore, pharmacists should consider the impact of cultural issues on Saudi asthma patients to achieve better clinical outcomes.

Published: March 2023

In this paper, we recount our research on undergraduate mathematics students learning to use programming for mathematics investigation projects. More precisely, we focus on how a particular theoretical perspective (the Instrumental Approach) helps us better understand this student activity. Pulling data from students' and instructors' experiences in a sequence of courses (offered since 2001), our results expose, at the micro and macro levels, how the student activity is organized (through stable 'ways of doing'), and highlights the complexity of this activity (as an intertwined web of 'ways of doing' involving a combination of both mathematics and programming competencies). We end with concrete recommendations to instructors.

Dans cet article, nous présentons notre recherche sur les étudiants de premier cycle en mathématiques apprenant à utiliser la programmation pour des projets d'investigation en mathématiques. Plus précisément, nous nous concentrons sur la façon dont une certaine perspective théorique (l'Approche instrumentale) nous aide à mieux comprendre cette activité de l’étudiant. S’appuyant sur des données des expériences d’étudiants et d’instructeurs dans une séquence de cours (offerts depuis 2001), nos résultats décrivent comment l'activité de l’étudiant est organisée (par le biais de «façons de faire» stables), et met en évidence la complexité de cette activité (comme un réseau entrelacé de « manières de faire » impliquant une combinaison de compétences en mathématiques et en programmation). Nous terminons par quelques recommandations concrètes pour les instructeurs.

De mujeres artesanas a la potencia feminista. Análisis de experiencias de mujeres mapuches en su participación de políticas estatales
Authors: Sabatella Maria Emilia , Sánchez Iudicello Suzette
Published: March 2023

Este trabajo tiene como objetivo analizar la participación de las mujeres mapuche en el marco de la implementación de dos proyectos financiados por políticas estatales. En primer lugar, el proyecto Xopun Bawehtuwun, de recuperación de memorias en torno al uso de las hierbas y la elaboración de preparados medicinales mapuche llevado adelante por la organización Epu Bafkeh de Los Toldos, provincia de Buenos Aires, Argentina. En segundo lugar, la experiencia de transmisión de la práctica del hilado y tejido a telar mapuche de las mujeres artesanas tejedoras de la Cooperativa Artesanal Zuem Mapuche, que nuclea a diferentes comunidades mapuche situadas en la línea sur y la zona andina de la provincia de Río Negro, Argentina. Durante la participación de estos proyectos, las mujeres actualizaron memorias colectivamente y produjeron alianzas que les permitieron discutir las lógicas de subordinación estatal y patriarcal que las atraviesan. En el desarrollo de nuestro trabajo, interpretamos a estas alianzas y a su potencial político como excesos de las políticas estatales. La particularidad de estos excesos es que, a la luz de las experiencias analizadas, desafían los condicionamientos y los estereotipos desde los cuales estas mismas políticas se formulan e implementan.

The aim of this research was to examine the influence of partial and total replacement of pork backfat with two quite different (in terms of sensory properties) plant oils (grapeseed and pumpkinseed oil) on instrumental colour and texture of frankfurters. The influence on colour was more pronounced when pumpkinseed oil emulsion was used as backfat replacer ­– these frankfurters were less red and more yellow than control and frankfurters with grapeseed oil emulsion. The effect was more pronounced with the increase of backfat replacement degree. No significant influence on instrumental texture parameters was observed.

Food-grade siloxanes are inert and therefore do not emit dangerous substances. Due to these properties, it is completely harmless, unlike technical silicone. FTIR spectroscopy was used to confirm the assumed mechanism of the crosslinking reaction of siloxane. The addition of highly active silicon (IV) oxide leads to an increase in hardness and tensile strength and affects the final properties of the cross-linked materials. The analysis of the thermal properties of the synthesized siloxane materials and their nanocomposites with the addition of hydrophilic and hydrophobic particles of silicon (IV) oxide was performed using a DSC device, which showed that the increase in the proportion of nanofillers significantly affects the values of the melting temperatures of silicone elastomer materials.

Tree Morus species are growing in Serbia, Morus alba, Morus nigra and Morus rubra. Morus leaves are used in traditional medicine, and after collecting them, drying is most practiced method for preservation. Hydrodistillation of 2 fresh and 2 dryed for one month samples of Morus alba and nigraleaves was done by using the original Clevenger-type apparatus. The composition of essential oils was determined by GC-MS aparathus. The yields of essential oils obtained by hydrodistillation were 0.0011 and 0.0012% from the dried plant material (MNL-2 and MAL-2, respectively) and 0.0080% (w/w) from both samples of fresh leaves (MNL-1 and MAL-1). The predominant constituent in all essential oils was trans-phytol. Only the essential oil obtained from dried M. alba leaves contained the chemical compound bovolid (8.1%). Based on results, bovolid can be used as indicator for evaluating the age of white mulberry leaves.
