CELLULAR AND MOLECULAR MECHANISMS OF MUSCLE REGENERATION
Authors: Qaisar Rizwan
Published: August 2022

BACKGROUND: Muscle injuries are a common manifestation of exercise and non-mechanical factors such as drugs, genetic defects, and systemic diseases. Despite their clinical importance, the cellular and molecular mechanisms of muscle injury and repair are poorly understood, which hamper development of effective clinical interventions. OBJECTIVE: This review is an attempt to recognize basic principles of skeletal muscle regeneration process. METHODS: A thorough systematic review of articles on muscle injury and repair processes was conducted using three reliable search engines for biomedical literature as ScienceDirect, Scopus and PubMed. REVIEW: Following injury, rapid activation and differentiation of satellite cells is major cellular repair process. At the molecular levels, activation of dysferlin and MG53 proteins help in building the ‘’repair cap’’ at injury site to initiate repair process. This event is followed by secretion of muscle myokines and subsequent infiltration of macrophages into muscle fibers, which remove cellular debris and activate other repair proteins and satellite cells. This review elaborates cellular and molecular mechanisms regulating these events following muscle injury. Effective therapeutic interventions to counter muscle injury-related atrophy remain elusive. Conclusion: Altogether, this review proposes cellular and molecular targets to accelerate muscle regeneration process following mechanical and non-mechanical injuries. Further investigations are required to elucidate the pathways dictating muscle regeneration process following injury.

OBJECTIVE: To explore the demographic differences on caregiver burden, hopelessness, and psychological distress among caregivers of psychiatric patients. METHODS: This descriptive cross-sectional study was conducted in Pakistan Institute of Medical Sciences Islamabad and Nishtar Hospital Multan, Pakistan in eight months from 10th April 2019 to 20th November 2019. Purposive sampling technique was used to include 240 caregivers of different age of Psychiatric patients (with different duration of illness and type of illness) which were assessed on Burden Scale for Family Caregivers, Kessler Psychological Distress Scale and Beck Hopelessness Scale. RESULTS: Out of 240 participants, 124 (51.6%) were females and 116 (48.3%) were males, ranging in age from 18 to 45 years. Results disclosed that age group 36-45 years showed significant mean difference on psychological distress and age group 18-35 years showed significant difference on hopelessness at p<0.01. While, caregivers dealing with patients who have illness for more than 20 years have significant mean difference on psychological distress and hopelessness at p<0.05. Caregivers dealing with patients who have less than 5 years of illness have significant mean difference on caregiver burden at p<0.001, and caregivers of patients with schizophrenia have significant mean difference with substance abuse, mood disorder and mental retardation on psychological distress and hopelessness at p<0.05. CONCLUSION: Older adults have higher psychological distress while, young adults have higher level of hopelessness. Caregivers of prolonged mental illness have higher psychological distress and caregiver burden. Caregivers of schizophrenic patients have higher level of psychological distress and hopelessness.
PANCYTOPENIA: A RARE PRESENTATION OF SYPHILIS
Authors: Badshah Aliena , Husain Syed Osama , Khattak Zoia Ehsan
Published: August 2022

INTRODUCTION: Syphilis is caused by spirochete Treponema pallidum. A common mode of transmission is via sexual contact and mainly targeting high-risk populations such as those with Human Immunodeficiency Virus and men who have sex with men (MSM). It has a wide range of presentations based on the four main overlapping clinical stages. Due to the lack of vaccines to prevent syphilis, prompt diagnosis and management of infected persons are warranted to reduce disease burden and its clinical effects.  CASE PRESENTATION: We present an unorthodox case of pancytopenia in a 55-year-old male patient who developed chronic progressive weakness, generalized body aches, and intermittent fever. His blood tests revealed pancytopenia and bone marrow biopsy revealed caseous necrosis. Since the patient had a positive history of MSM, syphilis serology was sent, which turned out to be positive. The patient responded to intravenous benzylpenicillin and oral doxycycline. CONCLUSION: Of note, not every pancytopenia in the elderly is due to malignancy, bone marrow aplasia or acute viral / parasitic insult; other uncommon causes also exist. Syphilis should be kept among the differentials of pancytopenia when more common causes have been excluded. A good sexual history is pertinent to reaching the correct diagnosis in such cases.

OBJECTIVE: To identify the topics difficult to understand in learning Anatomy and to investigate the reasons of difficulty and their possible solutions. METHODS: This descriptive observational study was conducted at Army Medical College, Rawalpindi, Pakistan from April to November 2019. Open ended and validated questionnaires were filled by 205 undergraduate medical students at the end of their academic year to ensure that complete course of anatomy including gross anatomy, histology and embryology were covered by students. Students were asked to specify the problem area, the subtopics, give the reasons for topics being difficult and mention possible solutions they think will help them in better understanding of these difficult areas. The problems having 5 or less number of responses were not included in the analysis. RESULTS: Embryology, histology & neuroanatomy were perceived as the most difficult areas by 89%, 62% & 61% of students respectively. Constraint of time (41% for gross anatomy & 26% for embryology), high difficulty level (35% for embryology & 29% for gross anatomy) and difficulty in differentiation of slides (34% for histology) were the main reasons for problems in understanding the topics. Use of more 3-D aids (61%) & revision classes along with written tests (39%) were commonest possible solutions for perceived difficulties by students. CONCLUSION: Embryology has been perceived as the most difficult topic of anatomy by the students of second year MBBS followed by gross anatomy and Histology. Time constrain was suggested as main reason and Use of 3-D aids as main solution for difficulties.

Published: August 2022

OBJECTIVES: To ascertain the temporal trends for the prevalence of diabetes, pre-diabetes and its associated selected risk factors among adults in rural areas of Baluchistan. METHODS:  This observational study used the data from three health surveys conducted in the rural areas of Baluchistan, a province of Pakistan in the years 2001-02, 2009-10, and 2016-17. Non-pregnant adults aged ≥20years and permanent residents of Pakistan were included. A well-trained team included doctors, health visitors, lab technicians, and volunteers who were involved in all surveys. Fasting plasma glucose samples were used for the diagnosis of diabetes as per World Health Organization criteria. The ethical approval of all the surveys was obtained and written informed consent was taken from all the participants. RESULTS:    A total of 2515, 1377, and 358 participants were included in the years 2002-03, 2009-10, 2016-17, respectively. The weighted prevalence of diabetes was 4.2%, 7.8%, and 31.9 % in respective survey years, along with the overall percent point change of diabetes up to 27% (P-value<0.0001). Moreover, rapid prevalence increases from the year 2002 – 2017 were also observed in hypertension (3.7% to 32.7%), obesity (15.7% to 88.1%), and dyslipidemia (82.2% to 95.3%), respectively (P-value<0.0001). However, multivariable logistic regression found a significant association between diabetes, pre-diabetes, hypertension, obesity, and dyslipidemia (P-value<0.05). CONCLUSION:       The most significant rise in prevalence of diabetes, prediabetes, hypertension in the young population, and dyslipidemia, obesity, and central obesity in all age groups need urgent, targeted socially acceptable but complex interventions to prevent poor CVD outcomes.
Photoluminescence wavelength from stacking fault with complicated structure in 4H-SiC epitaxial layer
Authors: Suo Hiromasa , Yamashita Tamotsu , Eto Kazuma , Miyasaka Akira , Osawa Hiroshi , Kato Tomohisa , Okumura Hajime
Published: August 2022

We investigated the photoluminescence wavelength emitted at room temperature from novel stacking faults with a complicated stacking sequence in the epitaxial layer on p-type 4H-SiC substrate. From analysis of photoluminescence imaging and synchrotron X-ray topography, we consider that these complicated stacking faults originate from p-type substrates. We investigated the relationship between photoluminescence energy and stacking sequence of various stacking faults, and confirmed that the maximum number of layers in complicated stacking faults determines the photoluminescence emission energy. This relationship, which was previously only reported for 3C-type stacking faults, follows simple quantum-well theory. We extended this theory to stacking faults with complex structures, focusing on the maximum number of layers.

Authors: Takyu Sodai , Shibuya Kengo , Nishikido Fumihiko , Tashima Hideaki , Takahashi Miwako , Yamaya Taiga
Published: August 2022

Positronium (Ps) is generated before electron–positron annihilation in positron emission tomography (PET). As the Ps lifetime reflects the surrounding electron density, we aimed at its use for an innovative PET imaging. Here, as our first step, we demonstrated two-dimensional Ps lifetime imaging of certified reference materials using a pair of time-of-flight PET detectors. The imaged and calculated Ps lifetimes were very close to those of the reference materials, but the error values were larger than those of the reference materials. The results suggested that the accuracy of PET imaging with the ortho-positronium lifetime could be verified by those materials.
Seroprevalence of Leptospirosis in Suspected High-Risk Sudanese Patients; A Pilot Exploratory Study
Authors: Abdelrahim Nada Abdelghani , Ibrahim Mohammed Wisal Mustafa
Published: August 2022

The extent of leptospirosis is unknown in Sudan, and it might be mistaken for other more common febrile infectious diseases. Leptospirosis might also be associated with renal diseases that are common in Sudan. We intended to explore the existence of human leptospirosis in suspected high-risk patients in Khartoum, Sudan, via sero-screening random febrile patients and those undergoing renal dialysis. This pilot exploratory study was conducted over six months, from April to September 2013. Four hospitals were selected conveniently following a non-random sampling approach. One hundred nineteen febrile patients (with or without definitive diagnosis) and patients under renal dialysis were included, and their serum specimens and clinical and demographic data were collected. Sera were screened qualitatively for the existence of anti-leptospiral IgM antibodies using a rapid lateral flow immune-sorbent assay. Ethical clearance and official permissions were obtained. Of the 119 patients, 57 (47.9%) had end-stage renal disease. They were under dialysis at Renal Dialysis Unit in Asbab Charity Hospital in Bahri, 47 (39.5%) were febrile with unknown origin attending the Tropical Medicine Hospital in Omdurman, and 15 (12.6%) were febrile and were diagnosed as having malaria or typhoid and attended Yastabshiron Medical Centre and Bashauer Teaching Hospital. The prevalence of anti-leptospiral IgM antibodies among all 119 screened patients was 7%. The prevalence among the 57 with the end-stage renal disease was 9%, and among the 47 with a fever of unknown origin was 6%. The prevalence among the 15 with a fever of known origin (diagnosed as malaria or typhoid) was 0%. Almost all positive patients had recurring episodes of fever, were in close contact with livestock, were farmers, and had an untreated natural source for drinking water. Human leptospirosis does exist in this targeted population. It is probably a common febrile condition and can be easily considered one of the major causes of chronic kidney disease affecting people in Sudan. A national sero-screening for leptospirosis among those living in high-risk geographical areas and those at occupational risk is highly recommended.

Published: August 2022

Children with cancer can have a severe disease when infected with respiratory viruses. In this study, we aimed to understand the clinical course and outcomes of SARS-CoV-2 infection in children with cancer. Data evaluated about laboratory-confirmed SARS-CoV-2 infections in sixty-three children (<18 years) with cancer between 01.06.2020 - 01.08.2021 were retrospectively reviewed. Data for demographics, oncological diagnosis, clinical course, and cancer therapy details were collected. Primary outcomes were disease severity and modification to cancer-directed therapy. The median (range) age was 7.6 ± 5.3 (0-18) years, and the most common underlying diagnosis was leukemia (74.6%). The most common symptom was fever (67.7%), and most patients had symptoms (70%). The mild disease was most common (60.3%). During Covid-19 infection, disease severity increased 23 times (p=0.003) in those with fever and 4.083 (p=0.045) in those with neutropenia. It was observed that the severity of the disease increased 2.589 times as CRP increased (p<0.001). However, few patients (9.5%) were admitted to the intensive care unit. Five patients died, but none of the deaths could be attributed to Covid-19 alone. Most patients did not experience chemotherapy treatment interruption (57%). When interruption did occur, this duration was 13.9±14.3 (1.0-60.0) days. In this cohort of pediatric oncology patients, nearly 43% of patients who had Covid-19 were their chemotherapy interrupted. Future studies will only reveal the final effect of the pandemic on childhood cancer.

Authors: Deka Prabir , Despande R A
Published: August 2022

Domperidone is a prokinetic drug used for diabetic gastro paresis, hiccoughs, and vomiting. As it has preferential action on the D2 receptors of the
upper gastrointestinal tract hence neurological side effects, and hyperprolactinemia are rarely reported. It is not known to cross the blood brain
barrier and hence, neurological side effects are rare. Stomach cramps, diarrhea, constipation, mastalgia are the rarer side effects which have been
observed. We would like to report a case of domperidone induced galactorrhea in a young female who presented with galactorrhea and breast
abscess along with pituitary microadenoma.

A Single-pass Noise Covariance Estimation Algorithm in Multiple-model Adaptive Kalman Filtering for Non-stationary Systems
Authors: Kim Hee-Seung , Bienkowski Adam , Pattipati Krishna
Published: August 2022

Estimation of unknown noise covariances in a Kalman filter is a problem of significant practical interest in a wide array of applications. This paper presents a single-pass stochastic gradient descent (SGD) algorithm for noise covariance estimation for use in adaptive Kalman filters applied to non-stationary systems where the noise covariances can occasionally jump up or down by an unknown magnitude. Unlike our previous batch method or our multi-pass decision-directed algorithm, the proposed streaming algorithm reads measurement data exactly once and has similar root mean square error (RMSE). The computational efficiency of the new algorithm stems from its one-pass nature, recursive fading memory estimation of the sample cross-correlations of the innovations, and the RMSprop accelerated SGD algorithm. The comparative evaluation of the proposed method on a number of test cases demonstrates its computational efficiency and accuracy.

Published: August 2022

 Non-Fungible Tokens (NFTs) do hold the promise of providing Web3 with the opportunity for self-sovereignty of users’ physical assets. In this paper, we propose a generic NFT architecture for Web3. The architecture supports the rapid development of the upper application environment and automated value mapping of the underlying physical asset environment. To connect these two environments, a generic connecter has been designed to provide flexible storage for mapping data management, and to support universal cross-chain transactions. With these features, the values of heterogeneous physical assets can coexist in a unified Web3 world, and rich value transfer services can be developed on demand. This paper discusses the background of the proposed architecture, the open problems and our initial solution, as well as our design principles and advantages, and finally validates this novel NFT architecture. 
Balanced Spanning Tree Protocol in Hierarchical NextGen Ethernet Networks
Authors: MIRJALILY GHASEM
Published: August 2022

Creation and maintenance of the spanning tree forwarding topology is an essential task in Ethernet networks. In standard Ethernet networks, Spanning Tree Protocol (STP) is responsible to do this task. In STP, some links will be disabled to provide a minimum-cost spanning tree. However, the constructed tree may be unbalanced. STP does not provide any mechanism for load balancing, results in unbalanced distribution of the traffic load and this may lead to congestion. In this paper, a new protocol named Balanced Spanning Tree Protocol (BASTP) is proposed to provide a balanced spanning tree in hierarchical topologies for using in next generation (NextGen) wired networks. Simulation results show that BASTP provides better load balancing and therefore better performance in comparison to the standard STP.

Published: August 2022

Long Range (LoRa) is one of the most promising and widespread chirp spread spectrum (CSS)-based physical (PHY) layer technique for low-power wide-area networks (LPWANs). Using different spreading factors, LoRa can attain different spectral/energy efficiencies, and can target multitude of Internet-of-Thing (IoT) applications. However, one of the limiting factors for LoRa is the low bit rate. Little to no effort has been made in order to improve the achievable rate of LoRa, until recently, when a number of CSS-based PHY layer LoRa alternative are proposed for LPWANs. In this survey, for the first time, we present a comprehensive waveform design of these CSS-based schemes that have been proposed between 2019 to 2022. In total, fifteen alternatives to LoRa are compared. Other survey articles related to LoRa mostly tackle different issues, such as LoRa networking, LoRa deployment in massive IoT networks, and LoRa architectures, etc. This survey, on the other hand, comprehensively elucidates the waveform design of LoRa alternatives. The CSS schemes studied in this survey are divided into single chirp, multiple chirp, and index modulation based on the multiplexing pattern of the chirps. Complete transceiver architecture of these CSS schemes is studied, and performance is evaluated in terms of energy efficiency (EE), spectral efficiency (SE), bit-error rate (BER) performance in additive white Gaussian noise, BER in the presence of phase and frequency offsets. It has been observed that the EE, SE and robustness against the offsets is primarily linked to transmit symbol frame structure. The  public versions of  the MATLAB codes for the CSS schemes studied in this survey shall be provided to promote reproducible research.
Role of Collaborative Resource Sharing in Supply Chain Recovery During Disruptions: A Systematic Literature Review
Authors: Mustapha Saidi , Ali Agha Mouhamad Shaker , Masood Tariq
Published: August 2022

The COVID-19 crisis has attracted attention worldwide to the supply chain disruptions and resilience. Several supply chain risk management approaches have been revisited or reapplied such as collaborative resource sharing. This study aimed to investigate the current academic state of art and advances in using collaborative resources sharing as a reactive method to facilitate supply chain recovery in the presence of disruptive events. More specifically we considered the role of different collaborative resource sharing strategies that organizations can adopt to support supply chain functionalities during times of disruption. We conducted a systematic literature review (SLR) to analyze academic articles that were published online from 2000 to 2022. In order to analyze the literature, we adopted a combination of text-mining, automatic and manual categorization of selected articles, and exploratory analyses such as cluster analysis and relational indicators. We also consider the machine learning classification algorithm i.e. agglomerative hierarchical clustering for the categorization of clusters. The findings show that, for disruptive risks, collaborative sharing of labour and material resources are effective for the recovery of supply chains. More so, labour resources tend to contribute more to the recovery of supply chains. Whilst information resources and a mix of information and material resources are highly important in reducing the impact of COVID-19 disruptive supply chain risk. In conclusion, collaborating on the three resources, namely labour, material, and information resources can be an effective post-disruption recovery strategy for supply chains. 
Robustness Properties of Local Maximum Synchrosqueezing Transform
Authors: Zhang Ran
Published: August 2022

The development of the synchrosqueezing techniques has been a very active research area in recent years. The synchrosqueezing transform (SST) is a powerful tool for time-frequency analysis of multicomponent nonstationary signals. The local maximum synchrosqueezing transform (LMSST) was recently introduced as a variant of SST. It directly uses the local maximum to reassign the time-frequency coefficient in order to obtain an energy-concentrated representation. However the theoretical foundation of LMSST is yet to be properly established. In this paper, we study the linear-chirp model based LMSST with the objective of obtaining its error bounds of mode separation/retrieval under noise-free and noisy conditions. Our theorems demonstrate the applicability of LMSST mathematically. Numerical experiments including synthetic and real-world signals are provided to illustrate the general theory.
A Constant Common Mode Voltage Single-Phase Five-Level Transformerless PV Inverter Considering the Effect of Switch Device Junction Capacitance

Published: August 2022

Constant common mode voltage (CCMV) is critical in Solar Photovoltaic (SPV) systems. Maintaining CCMV further eliminates the transitions in the voltage across the parasitic capacitance of the PV panel, making it a low-frequency output voltage waveform. This further reduces the leakage and common mode current in the SPV systems. This paper presents a five-level switched capacitor PV inverter configuration that maintains the CCMV with low-frequency terminal voltage while considering the effect of switch device junction capacitance (SDJC). Thus, the proposed configuration eliminates the transitions in the common mode and terminal voltage due to the SDJC. The two switched capacitors employed in the proposed configuration are charged and discharged within each switching period, supporting the self-charge balance feature apart from low voltage and RMS current rating, reducing its size and value. Further, the proposed system effectively utilizes the PV source as switch capacitors, and the dc-bus buffer capacitor across the PV source comes in parallel in each switching period. The proposed configuration can also operate at lower modulation indices generating three levels with CCMV. A new mathematical analysis considering SDJC is given for the derivation of expression for terminal voltage and CMV, which is further verified using simulation and experimental results 
GridTool: An Open-Source Tool to Convert Grid Data

Published: August 2022

This paper introduces the open-source GridTool software available at GitHub. It is an easy-to-use tool to convert and simplify electricity grid data from the OpenStreetMap-project for the use in energy simulation models. The main advantages of the newly developed tool are its flexibility, customizability and its heuristic approach for identifying grid nodes. Instead of the lengthy and predominantly manual process of converting and implementing electricity grid data from transmission and distribution system operators, the GridTool shortens that task to seconds. During this process the OpenStreetMap data gets reduced to the essential things that are needed in energy simulation models for load flow purposes, with optional plots that help to tweak the most important settings. To our knowledge there is no other open-source tool, that works out-of-the-box that does this task and is as easy-to-use, only needs one program to run (MATLAB) and uses a heuristic approach.
