Authors: Chandel Abhishish , Shankar Vijay , Kumar Navsal
Published: June 2023

Accurate hydraulic conductivity (K) estimation of porous media is crucial in hydrological studies. Recently, groundwater investigators have utilized neural computing techniques to indirectly estimate soil sample K instead of time-consuming direct methods. The present study utilizes easily measurable characteristics, i.e., grain size at 10 and 50% finer by weight, porosity, and uniformity coefficient as input variables to examine the efficacy of feed-forward neural network (FFNN), Kohonen self-organizing maps (KSOM), and multiple linear regression (MLR) models in estimating the K of soil samples. Model development and validation used 70 and 30% of datasets, respectively. The determination coefficient (R2), root mean square error (RMSE), and mean bias error (MBE) were used to compare the model performance with the measured K values. The study's outcome indicates that the FFNN and KSOM models better estimate the K value, while the MLR model performs merely satisfactorily. Overall, during validation, the FFNN model correlates better with the measured values having R2, RMSE, and MBE of 0.94, 0.016, and 0.006, whereas the corresponding values for KSOM are 0.91, 0.024, and −0.004, and that for MLR are 0.87, 0.024, and 0.013, respectively. Notably, the FFNN model exhibits superior prediction performance and can be employed in aquifers for precise K estimation.

Attenuation of NLRP3 Inflammasome by Cigarette Smoke is
Correlated with Decreased Defense Response of Oral Epithelial
Cells to Candida albicans
Authors: Huang Fan , Xie Ruiqi , Li Ruowei , Liu Liu , Zhao Maomao , Wang Qiong , Liu Weida , Ye Pei , Wang Wenmei , Wang Xiang
Published: June 2023

Background:

It is well recognized that both smoke and Candida infection are
crucial risk factors for oral mucosal diseases. The nucleotide-binding domain-like
receptor family pyrin domain containing 3 (NLRP3) inflammasome and its downstream
effectors, interleukin (IL)-1β and IL-18, are pivotal to the host defense against Candida
and other pathogens.

Methods:

The present study was designed to explore the effects of cigarette smoke and
C. albicans on the NLRP3 inflammasome and its downstream signal pathway via in vitro
cell model. Oral epithelial cells (Leuk-1 cells) were exposed to cigarette smoke extract
(CSE) for 3 days and/or challenged with C. albicans.

Results:

Microscopically, Leuk-1 cells exerted a defense response to C. albicans by
markedly limiting the formation of germ tubes and microcolonies. CSE clearly eliminated
the defense response of Leuk-1 cells. Functionally, CSE repressed NLRP3
inflammasome, and IL-1β and IL-18 activation induced by C. albicans in Leuk-1 cells.

Conclusion:

Our results suggested that in oral epithelial cells, the NLRP3 inflammasome
might be one of the target pathways by which CSE attenuates innate immunity
and leads to oral disorders.

The accumulation of amyloid-β (Aβ) is the main event related to Alzheimer's disease (AD)
progression. Over the years, several disease-modulating approaches have been reported, but without
clinical success. The amyloid cascade hypothesis evolved and proposed essential targets such as tau
protein aggregation and modulation of β-secretase (β-site amyloid precursor protein cleaving enzyme
1 - BACE-1) and γ-secretase proteases. BACE-1 cuts the amyloid precursor protein (APP) to release
the C99 fragment, giving rise to several Aβ peptide species during the subsequent γ-secretase cleavage.
In this way, BACE-1 has emerged as a clinically validated and attractive target in medicinal
chemistry, as it plays a crucial role in the rate of Aβ generation. In this review, we report the main results
of candidates in clinical trials such as E2609, MK8931, and AZD-3293, in addition to highlighting
the pharmacokinetic and pharmacodynamic-related effects of the inhibitors already reported. The
current status of developing new peptidomimetic, non-peptidomimetic, naturally occurring, and other
class inhibitors are demonstrated, considering their main limitations and lessons learned. The goal is
to provide a broad and complete approach to the subject, exploring new chemical classes and perspectives.
Drug Repurposing for Thioredoxin Interacting Protein Through Molecular Networking, Pharmacophore Modelling, and Molecular Docking Approaches
Authors: Kar Ayushi , Paramasivam Balamurugan , Jayakumar Darshini , Swaroop Akey Krishna , Selvaraj Jubie
Published: June 2023

Background:

Diabetes Mellitus (DM) has emerged as one of the major causes behind global
all-cause mortality between the age group of 20-79 years. Thioredoxin Interacting Protein (TXNIP) is a
naturally occurring protein that primarily acts by binding to TRX protein, thereby inhibiting its ability to
maintain the cellular reduced environment and subsequent oxidative stress, which leads to dysfunctional
insulin production and pancreatic islet beta cell apoptosis.

Objective:

By inhibiting the levels of TXNIP, a search for new molecules was carried out by employing
an in-silico approach.

Methods:

Molecular networking study was carried out using Cytoscape, wherein previously FDAapproved
drugs were screened to check their ability to interact with TXNIP. This provided 14 drug molecules,
which along with 11 previously obtained drug molecules that inhibit TXNIP, were subjected to
pharmacophore generation. A pharmacophore was generated using the PharmaGist web server, which
when visualised showed two hydrogen bond acceptors and one aromatic ring. Based on the generated
pharmacophore model, we carried out virtual screening using ZINCPharmer. A total of 116 HITs were
generated based on this pharmacophore model. We then subjected the 116 molecules to Molecular Docking
against TXNIP (PDB: 4GEI) by using PyRx and the standard molecules, metformin and rosiglitazone.

Results:

Compared to the standard, we found 10 molecules that had a better binding affinity towards
TXNIP. These 10 molecules were further taken for ADMET studies. From this, all 10 compounds showed
good significant ADMET properties.

Conclusion:

From the preliminary studies, these 10 molecules showed good activity in the reversal of
diabetes mellitus by reducing the levels of TXNIP.

Authors: Regai Imen , Bose Meruna , Hazari Animesh , Kandakueti Praveen Kumar
Published: June 2023

Background:

Diabetic peripheral neuropathy (DPN) is the most common complication of diabetes mellitus. Among all complications of DPN, diabetic foot (DF) can cause a myriad of symptoms and impact the quality of life. This study aimed to review the prevalence of DPN and DF in the Middle East and North Africa (MENA) region based on the publications available. This systematic review can be a cornerstone for further research and it summarizes the literature published on the prevalence of DPN and DF for the last two decades in the MENA region.

Methodology:

The databases, PubMed, ResearchGate, Scopus, Web of Science, Science Direct, CINAHL, and Cochrane were searched using relevant keywords for the study. Full articles in English since 2000, including keywords “Prevalence”, “Diabetic peripheral neuropathy”, “Diabetic foot”, and “MENA region” were reviewed in two phases. All authors screened the titles and abstracts of the articles individually, which was followed by a screening of full texts. A consensus was made among all the authors for the final selection of the articles based on the eligibility criteria.

Results:

Ten selected articles on the prevalence of DPN were reviewed in the first phase of the study, which reported varying prevalence rates among the different countries of the MENA region ranging from 9% to 61%. In the second phase, only two articles on DF prevalence were shortlisted. They reported the prevalence of DF as 4.6% and 18.1% in Jordan and Sudan, respectively.

Conclusion:

The prevalence of DPN in the MENA region is varied within a short period of time and the reported prevalence of DF is limited. This study projects a strong need of establishing early screening strategies for DPN and DF to prevent further complications and decrease healthcare burden.
PENYEARAH 1 FASA DENGAN FAKTOR DAYA MENDEKATI 1 DAN THD MINIMUM PADA SISTEM TENAGA LISTRIK DENGAN KONTROL ARUS RAMP COMPARISON CURRENT CONTROL
Authors: Nazif Hazlif
Published: June 2023

ABSTRACT:The use of electronic equipment used is increasing in the world of industry, offices, households and transportation. However, this electronic equipment produces a low power factor value and high Total Harmonic Distortion (THD) because in electronic equipment, there are electronic components that are non-linear (diodes, capacitors, transformers and toroids). Therefore, a ramp comparison current control is needed for the boost converter in the electric power system to improve the low power factor and reduce the high THD in the electric power system. The comparison results show that the rectifier without a boost converter produces a power factor value of 0.2252 and THD 268%. This means that the input current waveform is not nearly sinusoidal. Meanwhile, the rectifier with a boost converter using ramp comparison current control produces a power factor value of 0.9207 and a THD of 4%. This means that the input current waveform is nearly sinusoidal. Rectifier with boost converter controlled ramp comparison current control which is better than rectifier without boost converter.ABSTRAK:Pemanfaatan peralatan elektronik yang dipergunakan semakin meningkat dalam dunia industri, perkantoran, rumah tangga dan transportasi. Namun peralatan elektronik ini menghasilkan nilai faktor daya yang rendah dan Total Harmonic Distortion (THD) tinggi karena di dalam peralatan elektronik, terdapat komponen-komponen elektronik yang bersifat non linear (dioda, kapasitor, trafo dan toroida). Oleh karena itu diperlukan kontrol arus ramp comparison current control sebagai konverter boost pada sistem tenaga listrik untuk memperbaiki faktor daya yang rendah dan menurunkan THD yang tinggi pada sistem tenaga listrik. Hasil perbandingan menunjukkan bahwa penyearah tanpa konverter boost menghasilkan nilai faktor daya 0.2252 dan THD 268 %. Hal ini berarti bentuk gelombang arus input tidak mendekati sinusiodal.  Sedangkan penyearah dengan konverter boost menggunakan kontrol arus ramp comparison current control menghasilkan nilai faktor daya 0.9207 dan THD 4 %. Hal ini berarti bentuk gelombang arus input mendekati sinusiodal. Penyearah dengan konverter boost yang dikendalikan kontrol arus ramp comparison current control lebih baik daripada penyearah tanpa konverter boost.

Age Advocacy in the Social Media Age: Strategies to Achieve Peak Engagement on Twitter (Preprint)
Authors: Ng Reuben , Indran Nicole , Liu Luyao
Published: June 2023

BACKGROUND

Ageism has long manifested itself as one of the most pervasive yet least acknowledged forms of prejudice. However, the issue has slowly been gaining some long overdue recognition in public discourse. Over the last decade, many organizations aimed at serving the needs and interests of older adults have turned to social media platforms such as Twitter to improve the visibility of age-related issues. However, notwithstanding their growing presence and participation online, minimal attention has been paid to the use of social media among age advocacy groups. To achieve policy change, age advocacy organizations must first be able to mobilize audiences.

OBJECTIVE

Our study elucidates features of tweets that are associated with time to peak engagement.

METHODS

We collated 204,905 tweets spanning 12 years and from 53 organizations. Engagement score of each tweet was calculated through established metrics (e.g., summing up of likes, retweets, etc). We ran Cox models with tweet features as predictors, and ‘time-to-peak-engagement’ as the outcome. ‘Peak engagement’ (event) refers to engagement scores above the 75th percentile, and ‘time’—months/tweet to reach peak engagement.

RESULTS

As hypothesized, tweet features associated with peak engagement are inclusion of three/more hashtags (p < .001), visual elements—e.g., photos increased a tweet’s ability to reach peak engagement by over 4 times (p < .001); quote tweets increased engagement by 3 times (p < .001), compared to regular tweets, controlling for account-level covariates. Conversely, tweets from organizations with higher tweet volume were 40% less likely to reach peak engagement (p < .001), suggesting the value of selective tweeting.

CONCLUSIONS

Social media is an important catalyst for policy action. In enabling timely dissemination of ideas among users, social media has the potential to reach users on a global scale and at an exponential speed. Having delineated the strategies for peak engagement on Twitter, our study provides an invaluable resource for age advocacy organizations in their important movement to combat ageism.
Leveraging mHealth Technologies for Public Health (Preprint)
Authors: Velmovitsky Pedro Elkind , Kirolos Merna , Alencar Paulo , Leatherdale Scott , Cowan Donald , Morita Plinio Pelegrini
Published: June 2023

UNSTRUCTURED

Traditional public health surveillance efforts are generally based on self-reported data. Although well validated, these methods may nevertheless be subjected to limitations such as biases, delays, and costs or logistical challenges. An alternative is the use of smart technologies (eg, smartphones and smartwatches) to complement self-report indicators. Having embedded sensors that provide zero-effort, passive, and continuous monitoring of health variables, these devices generate data that could be leveraged for cases in which the data are related to the same self-report metric of interest. However, some challenges must be considered when discussing the use of mobile health technologies for public health to ensure digital health equity, privacy, and best practices. This paper provides, through a review of major Canadian surveys and mobile health studies, an overview of research involving mobile data for public health, including a mapping of variables currently collected by public health surveys that could be complemented with self-report, challenges to technology adoption, and considerations on digital health equity, with a specific focus on the Canadian context. Population characteristics from major smart technology brands—Apple, Fitbit, and Samsung—and demographic barriers to the use of technology are provided. We conclude with public health implications and present our view that public health agencies and researchers should leverage mobile health data while being mindful of the current barriers and limitations to device use and access. In this manner, data ecosystems that leverage personal smart devices for public health can be put in place as appropriate, as we move toward a future in which barriers to technology adoption are decreasing.

Authors: Liu Junjie , Qiao Xi , Xiao Yi , Deng Zhuofan , Cui Ji , Wu Mingdong , Zhang Haolong , Ran Kun , Luo Hailong , Tang Bo
Published: June 2023

BACKGROUND

Operating surgeons can experience work-related physical and mental health impairments that may contribute to chronic muscle damage, burnout, and even withdrawal. However, camera-holder assistants in laparoscopic surgery may also experience similar issues, which are often ignored.

OBJECTIVE

We assessed the difference in physical and mental health impairments between operating surgeons and camera-holder assistants.

METHODS

A one-year survey of operating surgeons and camera-holder assistants evaluated the occurrence of muscle pain, fatigue, verbal scolding, and task load (i.e., mental, physical, perceptual, and anxiety) during laparoscopic surgery for benign diseases.

RESULTS

Among 2184 laparoscopic operations (69.16% of the total operations), 81% (operating surgeons) and 78% (camera-holder assistants) reported experiencing muscle pain/discomfort during the procedure. The anatomic regions were mainly concentrated in the shoulders and upper limbs (operating surgeons) and in the lower back and shoulders (camera-holder assistants). The VAS scores for operating surgeons and camera-holder assistants were 2.8 and 2.4, respectively, P<0.001. Additionally, 73.2% (operating surgeons) and 61% (camera-holder assistants) reported that muscle pain persisted postoperatively. Intraoperative fatigue was reported by 41.7% (operating surgeons) and 51.7% (camera-holder assistants). More than half (55.2%) of camera-holder assistants reported being verbally scolded by operating surgeons during the operation, and 64.6% of them believed that the scolding was mentally stressful. The reason for the scolding was mainly due to the poor coordination of laparoscope movement. After weighted scoring, the physical health impairment score of laparoscopic surgery for operating surgeons and camera-holder assistants was 2.7 vs. 1.6 (P<0.001), and the mental health impairment score was 3.4 vs. 3.2 (P<0.001).

CONCLUSIONS

The physical and mental health impairments experienced by camera-holder assistants during laparoscopic procedures, while less severe than those experienced by operating surgeons, should not be ignored.
Brain-computer interfaces: barriers and opportunities to widespread clinical adoption (Preprint)
Authors: Neves Diogo , Sá Juliana , Calado Maria do Rosário , Martins Henrique
Published: June 2023

BACKGROUND

Brain-computer Interface (BCI) is an emerging neurotechnology with potential applications primarily for neurological disorders. There is a rising interest in the clinical use of BCI to improve quality of care.
Despite their therapeutic potential, BCI use is still mostly limited to research stages and its translation into mainstream clinical applications and widespread adoption is lagging.

OBJECTIVE

This study revises the current potential clinical applications of BCIs in humans, attempts to understand barriers and opportunities to wider clinical adoption of this radical innovation in neurological-related care and draws its health policy and management implications.

METHODS

The methodology followed a two-step approach which included a systematic review of potential clinical applications of BCIs and a qualitative study, using focus group method, to understand and integrate professionals’ experiences, perceptions, thoughts and feelings on the wide clinical adoption of BCIs.
The systematic review aimed to review potential relevant clinical applications of BCIs and included 25 studies, published from 2017 to 2021. The qualitative study included 3 focus groups with a total of 22 participants from medical, engineering and management fields.

RESULTS

Clinical evidence of BCI applications included predominantly neurorehabilitation with non-invasive devices and the control of assistive devices with invasive BCIs (e.g., upper limb rehabilitation in stroke patients or control of spelling systems in LIS patients).
Several barriers to wider clinical adoption of BCIs were identified, mostly these were technological barriers like materials biocompatibility and insulation, miniaturization, wireless interfaces and batteries, advanced signal processing and recalibration. Nowadays, with the current pace of technological development, these technological barriers seem addressable in the near future. However, to achieve mainstream clinical applicability, BCIs will have to deal with systemic barriers to innovation in healthcare ecosystem.
A comprehensive and multidisciplinary approach will be needed to integrate and adopt BCIs in clinical contexts.

CONCLUSIONS

The successful integration of BCIs into clinical practice requires a multifaceted approach that addresses various barriers. This includes ensuring the clinical relevance of BCIs, securing funding and addressing potential negative impacts. It is essential to engage with end-users to understand their needs and perspectives and to work collaboratively across private and public institutions to create opportunities for the widespread use of BCIs. The involvement of medical doctors and the development of clinical guidelines will also be crucial for the adoption of BCIs. Ultimately, a concerted effort to engage with a wide range of stakeholders and to foster confidence and support for these devices will pave the way for progress in healthcare contexts.

Abstract: Nodes are building blocks of telecommunication network which are interconnected by telecommunication links for exchanging messages and data. Broadband Integrated Services Digital Network commonly called as Broadband ISDN or BISDN is a high-speed telecommunication network that carry data, voice and video simultaneously over a single channel. It provides interactive services where there is bidirectional flow of information between one or more subscribers and a service provider or distributive services with unidirectional information flow between service provider and subscriber. Speed of B-ISDN normally ranges from 2 Mbps to 1 Gbps and transmission very much relates to Asynchronous Transfer Mode. To design BISDN services for small scale organization, resource management and organization requirements play an important role. This paper provides a design of network model and implementation of broadband services for a small-scale organization by considering advance technology requirements, the challenges faced during the implementation and total estimation of budget for entire implementation.

A Laboratory Study of Use of Crumb Rubber as Partial Replacement of Fine Aggregate in Concrete
Authors: Soren Amit Kumar
Published: June 2023

Abstract: The aim of this study is to analyse the effect of addition of crumb rubber on the various properties of concrete. The crumb rubber is used as replacement over aggregates in the concrete mix. Crumb rubber is prepared from the scraps of tyres. In this study aggregates are replaced by 0%, 30%, 40%, 60%, 100% crumb rubber. The rubberized concrete is tested for slump and compression strength. It is found that the slump of rubberized concrete increases first but as the amount of rubber is increased the slump starts decreasing. It is observed that initial compression strength of rubberized concrete reduced significantly but the final strength is found to be more than that of ordinary concrete. Waste tyres cause tremendous pressure and ecological issues for the entire tyre industry when accumulated in cultivated land or combusted. Crumb rubber (<5 mm) grinded from waste tyres was introduced to substitute for natural fine aggregate in concrete and effectively solves the consumption challenge. This paper reviews the performance of concrete with crumb rubber as fine aggregate, providing evidence for crumb rubber concrete (CRC) materials design and application. Crumb rubber is characterized with light specific gravity, hydrophobicity and air entrapment in comparison with natural fine aggregate, inducing significant reduction in workability of fresh CRC and exhibiting poor bonding performance with cementitious matrix. By summarizing the compressive/tensile strength, elastic modulus and fracture behaviour of CRC at various rubber content, prediction models of strength reduction factors are proposed. The main reasons for strength deterioration are weak interface transition zone (ITZ) performance and non-uniform distribution of rubber particles. Water/chloride permeability, electrical/carbonation resistance and drying shrinkage of CRC are discussed for durability performance of CRC. Physical/chemical pre-treatments of rubber could alleviate the hydrophobicity and improve the mechanical and durability performance of transition zones between rubber and cement paste. Accordingly, scopes concerning the recycling of crumb rubber and its performance optimization are expected in future studies.

El tequelite chico (Peperomia peltilimba C. DC. ex Trelease) es una planta nativa y silvestre de México, considerada vulnerable a la extinción. El objetivo de este estudio fue documentar el conocimiento y la percepción sobre la conservación y el uso del tequelite chico en la comunidad totonaca de Chipahuatlan, Olintla, en el estado de Puebla (México). Se aplicaron 53 entrevistas semiestructuradas a una muestra representativa de la población; se consideró como universo al número de familias. La entrevista estuvo conformada por las secciones, conocimiento de la especie, conservación, comercialización, usos y beneficios. Se realizaron recorridos en el hábitat natural de la especie para documentar flora y fauna acompañantes. Los resultados indicaron que los tallos y hojas del tequelite chico se utilizan para la elaboración de alimentos tradicionales como mole, caldos, tamales y frijoles hervidos con o sin ajonjolí. La especie se obtiene a través de su hábitat natural y en tianguis locales, aunque algunas familias tienen plantas en sus traspatios. Los conocimientos tradicionales sobre el tequelite chico están relacionados con la flora y la fauna, se aprovechan solo las plantas más desarrolladas y se conservan las que presentan brotes o inflorescencias. Se identificó interés por conservar este recurso debido a su importancia cultural y económica; aunque su valor comercial es bajo, representa un ingreso adicional para las familias que se dedican a su recolección. Estos resultados son una aproximación al conocimiento totonaca y su percepción en torno a la conservación y el aprovechamiento del tequelite chico.
