Foreward V1 N1
Authors:   CBE DL, Patron for the International Journal of Cardiodiabetes, of Chelsea Lord Bilimoria
Published: April 2022

It is a great honour to have been asked to write the foreward to the inaugural edition of The International Journal of cardiodiabetes. At such a time with the COVID Pandemic still raging in many parts of the world, one might reasonably ask why at this time we need to have yet another medical journal in addition to the numerous publications that already exist? However, it is precisely the mortality, morbidity, geographical spread, economic effects, social disruption and inequalities which the Pandemic has highlighted that merit an even wider view of the importance of global healthcare. Whilst COVID is a global communicable disease, diabetes mellitus is in many senses a non-communicable equivalent with an ever burgeoning significance.

Cardiomyopathies are defined as “myocardial disorders in which the heart muscle is structurally and functionally abnormal, in the absence of attributable coronary artery disease, hypertension, heart valve or congenital heart disease”. This is an aetiologically and clinically diverse group of conditions, sharing important characteristics such as risk of sudden cardiac death (SCD) and possible heritable nature. Accurate phenotyping is key to the diagnosis and management for both probands and their relatives. Cardiovascular magnetic resonance (CMR) is central in this process, offering comprehensive multi-parametric assessment, enabling not only accurate phenotyping, but also identifying prognostic risk markers. We review the key aspects of CMR technique and the diagnostic and risk stratification applications of CMR in cardiomyopathy.

The study of peristaltic motion is an area of increasing research interest in industrial, biological and engineering interest. In this study, effects of slips on the peristaltic flow and heat transfer of micropolar fluids in an asymmetric channel are investigated analytically. The developed non-linear coupled partial differential equations are converted into non-linear coupled ordinary differential equations using similarity transformation. The ordinary differential equations are solved for the cases when the thermal viscosity parameter is zero and non-zero. Exact solutions are gotten for the cases of linear and non-linear when the thermal viscosity parameter is zero and non-zero, respectively. The obtain results depict that viscous and thermal slips enhances the flow of the bolus as it is being transported through the digestive system. Also, the effect of microrotation helps in reducing the pressure gradient for the flow.
“My Father’s Face”: Judaism, God, and Ritual Practice in Philip Roth’sEveryman,Indignation, andNemesis
Authors: Kessler Samuel J.
Published: April 2022

This article is about the occurrence and centrality of distinctly Jewish ideas and ritual practices in Philip Roth’s Nemesis (2010), Indignation (2008), and Everyman (2006). In these three novels, Roth constructed characters whose existential crises most often come during or when meditating upon moments of Jewish ritual or Jewish theological expression, and what emerges is that the when, where, and how moments in which Roth’s protagonists interact with Judaism are particularly Judaic. When they are practicing Jewish ritual or speaking in Jewish terms, Roth’s characters end up creating meaning through what Stephen Kepnes calls the great theatrical performance of Judaism.
An “Ambiguously Menacing Predicament”: Reading The Plot Against America in the Age of Donald Trump
Authors: Cuny Andy Connolly
Published: April 2022

This article offers a critical reassessment of the ways in which Philip Roth’ s The Plot Against America (2004) has been read in the era of Donald Trump. It questions how efforts to apply a politics of liberal anti-fascism to the text imply Roth’s unquestioned support for the moral and intellectual frameworks of contemporary liberal opposition to Trump. This article explores how Roth’s formal concerns with issues of ambiguity, irony, and contradiction resist the corralling of his fiction to suit any particular ideological aspiration or unquestioned moral perspective, no matter how perceivably liberal and anti-authoritarian in its creedal outlook. Indeed, as this article makes clear, Roth’s concern with the resistance of literary expression to polemical sloganeering is made evident by the ways in which The Plot Against America subjects the cohesive liberal values of its main characters to what Lionel Trilling outlined as the disaggregating impact of novelistic discourse. As this article discusses, Roth’s examination of the limits of liberal subjectivity in The Plot Against America offers an altogether new way of thinking about how the novel may be read in the context of our own troubled times.
Benthic macrofaunal habitat use of the alga Caulerpa prolifera compared to the seagrass Halodule wrightii
Authors: Nelson Walter G , Virnstein Robert W , Barkaszi Mary Jo
Published: April 2022

The abundance and species composition of the macrofauna inhabiting adjacent beds of the seagrass Halodule wrightii and the attached macroalga Caulerpa prolifera were compared seasonally from eight sites sampled within the Indian River Lagoon, Florida during 1987–1988. At each site, sampling employed a benthic corer, an epifaunal sampler, a dipnet, and fish traps to examine utilization patterns of different components of the fauna. Abundance of animals in both habitats was both high and similar. Epifaunal invertebrate densities averaged over 16,000 m−2 from H. wrightii and over 20,300 m−2 from C. prolifera. Despite a few species-compositional differences, there was no consistent difference in either the abundance or number of species of the macrofauna of C. prolifera versus H. wrightii for any sampling method except fish traps. Fish were significantly more abundant, but not more species rich, in H. wrightii. We conclude that C. prolifera offers habitat for many small invertebrates comparable to that of seagrass, making C. prolifera beds a valuable biological resource. While C. prolifera habitat may not support all the ecosystem services of seagrass beds and is not currently protected in Florida, it as a potential vegetated habitat refugium and may warrant management and protection practices similar to those for seagrass beds.

Authors: Singgih Purnomo  , Rayhan Gunaningrat
Published: April 2022

The Indonesia Career Center Network (ICCN) survey in 2017 showed that 87 percent of Indonesian students chose study programs at universities that did not match their interests. One of the impacts of choosing a study program that is not in my interest is the possibility of delays in completing the education period on time and not maximizing the pursuit of the best results. Seeing these empirical conditions, this study aims to explain whether internal factors or external factors more significantly influence student interest when choosing a study program in higher education. Internal factors are represented by self-motivation, ideals, and desires. Meanwhile, external factors are represented by the image of the university, family support, and previous school support. This research was conducted at Universitas Duta Bangsa Surakarta with a sample of 339 students from various study programs selected at random. Data were collected using a digital questionnaire. The Likert scale became a data measuring tool and was analyzed using the Structural Equation Model (SEM). The results of the analysis show that internal factors have more influence on student interest when choosing a study program at the university level.

Published: April 2022

Abstract– This study aims to produce a single-phase synchronous generator with an AC-DC-AC system using an EGS002 driver board that produces a pure sine wave of 50 Hz. This synchronous device system first converts alternating current (AC) to direct current (DC) to facilitate the generator synchronization process, then converts it back into alternating current (AC). The EGS002 driver board uses IC EG8010 as a control chip and IR2113S as a driver chip that produces square waves with two frequencies: low frequency 50 Hz and high frequency ± 1 KHz. The EGS002 driver board generates a square wave, then amplified by a full-bridge IGBT. This synchronous device uses a series of inductors with a capacitor as a lowpass filter which converts both square waves into a pure sine wave of 50 Hz.

Treatment of gingival recession

Published: April 2022

This case report describes about treatment of gingival recession. Introduction: The increasing esthetic demands from patients has required that clinicians sharpen their skills and adopt newer and more novel techniques to satisfy these demands. In periodontal therapy, periodontal plastic surgery poses a substantial challenge to the clinician, both because it is technique sensitive and also because it includes a wide array of procedures and their variations. Conventional plastic procedures have provided satisfactory results in the treatment of gingival recession but there is, presently, a greater need for more advanced procedures that cause less surgical morbidity as also provide improved results. Minimally invasive surgery has been harnessed in periodontics for this purpose and has been extensively used in multiple indications, including root coverage. Novel-Vestibular Incision   Supra-periosteal Tunnel Access (N-VISTA) applies the principles of minimally invasive surgery to provide satisfactory results in root coverage. Very less literature is available about the success of N-Vista Surgery in Mandibular arch. Case presentation: A 23-year-old female patient presented with localised Miller Class I/II buccal recession defects on mandibular anterior teeth.

Investigations into the oral health of the elderly leave little doubt that disease and dysfunction galore, though there is some disagreement about how clinical findings translate into treatment needs. The disabled and the institutionalised appear to be the most vulnerable, whereas dentists appear to be uninterested in providing services outside the scope of traditional dental practice. As a result, the oral health concerns of the elderly, particularly those relating to prosthodontic treatment, remain largely unaddressed.

These disfigurements can be congenital deformities such as cleft lip, cleft palate or acquired deformities such as accidental injuries. The rehabilitation needed is more because of patient’s psychological and emotional demands rather than their physical deficits. The purpose of this article is to give a piece of in-depth knowledge and discussed the various maxillofacial materials and their recent advances. Although the current clinical scenario concerning the field of a maxillofacial prosthesis is promising, improvement in material and techniques to be expected in the future to have better results.

Aim: Aim of the study is evaluate the efficacy of HBSS, Green tea extract and Aloe Vera gel as storage media in maintaining the viability of periodontal ligament cell. Material and Method: Fifty- five human teeth with closed apices and with apparently normal periodontium were extracted as atraumatically as possible for orthodontic reasons were collected for study. Teeth were randomly divided into positive control group, negative control group, three experimental group. Teeth in experimental groups were dried for 30 minutes (including time taken for curetting coronal PDL cells), followed by a 45-minute immersion in one of the three storage solution groups. The teeth in positive control group after extraction was immediately treated with collagenase. The teeth in negative control group were bench- dried for 8 hours, with no follow- up storage solution time, and then placed in the collagenase. Result: HBSS is the best medium for the maintaining the viability of the PDL Cells.But easier availability and cost effectiveness, GTE and Aloe Vera Gel can be advocated as a viable storage medium. Conclusion: It can be concluded that GTE and Aloe Vera Gel can be advocated as a viable storage medium.

Backgrounds: Since December 2019, when the coronavirus 2019 (Covid-19) first appeared in Wuhan and quickly spread throughout China, data on the clinical characteristics of the infected patients have been needed (Guan et al. 2020). Diabetes mellitus (DM) is a metabolic alteration characterized by chronic hyperglycemia. DM is considered one of the most common comorbidities in COVID-19 patients (Conget 2002). Aim: To identify the clinical variance between Covid-19 patients with and without DM (type II). Methods: The study contain 132 patients divided into four groups, there was 66 patients of them infected by COVID-19 with or without diabetic. The study was started from September 2021 to February 2022. Results: The results of the study appeared elevation the values of the most parameters measured for patients with/without diabetic such as D-dimer, ALT, AST, Blood Glucose, and Ferritin. But no change in Bilirubin and Alkaline phosphate (ALP). Conclusion: The COVID-19 patients with DM (type II) may be have the highest risk factors, which can increase the mortality, elevate the inflammation markers and affect the life enzymes (ALT, AST).

Background: Age & Gender determination is a crucial part of forensic researches & investigations. Mandibular parameters, condyle and ramus, in particular have been proved to show a high sexual dimorphism with respect to the development growth patterns and rates. Panoramic radiographs are often used in daily routine dental practices to assess mandibular and maxillary essential structures. The present study is conducted to assess the variations seen in measurements of gonial angle and bigonial width of mandible with age and gender. Materials & Methods: Study Comprises randomly selected 200 OPG (100 male, 100 Female) dentate age range from 11 to 80 years from Oral Medicine & Radiology Department. Any defect, anomaly were ruled out. Sample was divided into seven age groups. Bigonial angle and Gonial Angle were digitally measured. The collected data from the subjects were analysed using the SPSS version 25. Independent t-test, Paired t-test, one-way ANOVA and Discriminant analysis were used for comparison. Parameters were studied according to gender, side and different age groups. Results: Females have significantly larger value of gonial angle than males, but lower bigonial width. (p-value=0.00) Males have low value of gonial angle, but longer bigonial width than female (p-value=0.00).

Background: Green tea is a natural product, commonly used by women for multiple purposes. Epigallocatechin gallate (EGCG), the major catechin in green tea, exhibits several useful biological effects, including anti-inflammatory, antiproliferative, and antioxidant effects. A study conducted by the US Department of Agriculture reported that green tea has potent anticancer effects against a wide range of human cancer cells. Green tea’s polyphenols are considered responsible for these positive effects, and most notably EGCG has been shown to inhibit key pathways of tumor growth. Objective: Aim of the work was to study the effects of epigallocatechin gallate (EGCG), an extract of green tea on human leiomyoma and quality of life in women with symptomatic uterine fibroids. Patients and methods: A Prospective, sealed envelopes, randomized control trial was conducted including 75 reproductive-age women with symptomatic uterine fibroids (UF) were recruited for this study. All subjects had at least one fibroid lesion ≥ 2 cm³, as confirmed by transvaginal ultrasonography. The subjects had been randomized by SNOSE (Sequentially Numbered Opaque Sealed Envelopes); to oral daily treatment with either 900 mg of green tea extract or only symptomatic treatment for 4 months. The duration of study was about 3 years.
