Global PV Supply Chains: Costs and Energy Savings, GHG Emission Reductions
Authors: Shen Xiao , Liu Jie
Published: May 2023

In the battle against climate change, accelerating clean energy development is crucial. A global supply chain and cooperation in renewable energy technologies are vital for success. However, the increasing trend towards domestic protectionism in the clean energy sector may result in significant cost increases and hinder efforts to tackle climate change. Our study examined the cost savings, energy savings, and greenhouse gas emissions reduction achieved through a globalised solar PV module supply chain compared to a hypothetical scenario where domestic manufacturers supplied an increasing proportion of installed capacities over ten years from 2004 to 2021. We focused on five representative countries: China, the United States, Germany, Japan, and India. Our analysis revealed substantial cumulative savings in these countries, with cost savings totalling US$181 billion (165-179 billion), energy savings reaching 2.26 EJ-eq (1.99-2.56 EJ-eq), and greenhouse gas emissions avoidance amounting to 105 Mt CO2-eq (73-145 Mt CO2-eq). Future projections from 2022 to 2050 under two IEA scenarios indicate continued savings. This analysis highlights a globalised supply chain's significant cost, energy, and emissions benefits. Coordinated policy reforms are needed to facilitate clean energy trade and technology transfer to achieve global environmental goals.
Forecasting the health expenditures in Iran by Using Time Series Analysis as Machine Learning Model in Python
Authors: Hedayati Maryam , Asl Iravan Masoudi
Published: May 2023

Background:
Forecasting the future trend of health expenditures is an important step to achieve universal health coverage (UHC) by 2030. This study aimed to examine the two decades underlying historical trends in Iran’s health expenditures and explore these data as the grounds for forecasting its health expenditures.
Methods:
Iran’s health spending data spanning 2001–2019 were extracted from the National Health Account 2020 database. Total health expenditure, government, prepaid private, and out-of-pocket spending per capita were forecasted for 2020–2030. The Autoregressive integrated moving average (ARIMA) model was used to obtain future projections based on time series analysis. Python programming language has been used for prediction.
Results:
The model of total health expenditure (THE), government health expenditure (GHE), social health expenditure (SHE), prepaid private health expenditure (PPHE), and out-of-pocket health expenditure (OOP) are ARIMA (0,2,2), ARIMA (1,2,3), ARIMA (1,2,2), ARIMA (1,1,2), and ARIMA (1,2,0). According to the simulation results, in 2030, Iran’s THE is expected to reach 16,555,761,416 billion IRR, and the constituent ratios in GHE, SHE, PPHE, and OOP will be 29%, 28%, 11%, and 32%, respectively.
Conclusions:
Forecasting health expenditures is important in ensuring sustainable financing for the health sector, which is a critical aspect of achieving UHC. Our result would help policymakers to make sufficient data available in order to plan the future of resources and estimate the amount of the budget allocated to Healthcare. Iran should take effective measures to control the excessive growth of THE, keep decreasing the OOP percentage, and improve the efficiency and fairness of the use of health funds.

Authors: Roungrid Sittisak , Khwunnak Chadarat , Lertkonsarn Samran
Published: May 2023

The design of the active RC integrator presented in this research utilizes a fully balanced technique and current-tunable frequencies to create the active RC integrator and reliable circuit. The circuit is made up of six npn bipolar junction transistors (BJT), six resistors (R), and a capacitor (C), with the fully balanced technique used to make the circuit structure uncomplicated and symmetrical with signal differencing. This approach results in a low number of internal devices in the circuit, making it an attractive option for integrated circuit (IC) development. One of the key features of the fully balanced current-tunable active RC integrator is its ability to be frequency-tunable with bias current (If). This feature enables the circuit to be used in a variety of applications, including filter circuits, communication signal generators, instrumentation signal generators, and various automatic controls. The fully balanced design also ensures that the circuit is stable and robust, even in the presence of device parameter variations. To evaluate the performance of the active RC integrator, simulations were conducted using Pspice.

The results show that a fully current-tunable active RC integrator can be precisely tuned with the active bias to a value consistent with the theoretically calculated value. This demonstrates the efficiency and reliability of the circuit design and simulation method. The Monte Carlo (MC) method was also used to analyze the circuit performance in cases where the resistor (R) and capacitor (C) device had a 10 percent error and the transistor gain (β) was set to an error of 50 percent. The MC analysis showed that the phase shift (degree) and magnitude (dB) of the circuit were stable, and the circuit's performance was not significantly impacted by the device parameter variations. This further demonstrates the robustness and versatility of the fully balanced current-tunable active RC integrator design. Finally, harmonic distortion was evaluated to confirm the performance of the designed and developed fully balanced current-tunable active RC integrator. The results showed low levels of harmonic distortion, which indicates that the circuit is suitable for high-performance applications that require low distortion

Birch juice is a drink made of birch sap of medium-sized wild trees at the springtime. It is popular especially in northern Europe and Asia on territories with occasionally waterlogged permeable soils. However, some of these areas coincide with highest tritium leakage ever recorded (Kyshtym, Chernobyl and Fukushima). Robust analyses on tritium levels (scintillation method) in the birch sap were carried out in location with a constant load of tritiated water between 2003 and 2016. Sampling the birch sap was carried out annually in season (usually from the final week of February to the first-week of April. Sampling of birch sap was usually has been carried out during the period when the daytime air temperature was within +(5–8) °C minimum for 3 days. During this period, began intensive sap flow. Data obtained is put in relation to air temperature and humidity in order to contribute to the understanding basic mechanisms of tritium intake via birch. Findings confirmed that tritium easily penetrates via water into any organism and it can accumulate there for much longer than its half-decay times. It was firstly revealed that it is possible to predict the concentration of this dangerous pollutant in the birch sap based on the temperature and humidity dynamics. And with continuous input of tritium into the environment, the concentration of tritium in free water increases polynomial. The specific tritium activity values due to the gradient of tritium concentration in the atmosphere-plant-ground system of the change in temperature and humidity. For the organization of monitoring and control, the possibility of radioecological safety for the affected areas was determined

By examining the historic settlement of the Balochi people from West Asia to East Africa, this article seeks to study and examine their past immigration patterns, presence and current socio-political situation as a minority Muslim population. The Balochi people are an Indo-European ethnic Sunni Muslim minority population located in a region currently shared and divided by modern Islamic republics of Iran in West Asia and Pakistan in South Asia. The Balochis have formed a significant part of the non-indigenous Muslim population in East Africa since the late 17th century. Yet, there is not much written on them as a distinct Sunni Muslim minority group originating from historic Iran (including parts of South Asia) to Africa. Being part of a larger project, this study will explore the chief reasons behind the immigration of the Balochis to the regions of East Africa and how did their presence affect the local population and vice versa. The hypothesis is that the Balochis were formerly welcomed by the indigenous and non-indigenous population of East Africa and established amicable relationships with them. Using the method of qualitative content analysis combined with historical analysis, this article highlights the reciprocal impacts of the Balochi immigrants and indigenous people of East Africa.

Published: May 2023

Dalam falsafah, istilah “bahasa agama” bertujuan memberikan penjelasan tentang makna ayat dan ungkapan agama. Dalam tradisi intelektual Melayu, bahasa agama lazimnya dirujuk sebagai bahasa dalam teks-teks Islam, yang dikaji di bawah payung pengajian Islam, seperti tafsir al-Quran, ilmu kalam atau ilmu tauhid, usul fikah dan tasawuf. Namun begitu, kepentingan bahasa agama dalam falsafah Melayu seolah-olah diabaikan, baik dalam falsafah agama mahupun falsafah bahasa. Makalah ini membincangkan faktor pengabaian bahasa agama dalam falsafah Melayu dan peningkatan kepentingan bahasa agama dalam falsafah Melayu kontemporari. Data perbincangan ini ialah empat isu bahasa agama yang tercetus ekoran usaha kefalsafahan beberapa pemikir Muslim Melayu untuk menjelaskan makna ayat dan ungkapan agama. Terdapat faktor yang menyumbang kepada pengabaian bahasa agama dalam falsafah Melayu, seperti pesimisme Melayu terhadap falsafah dan peruntukan undang-undang yang memelihara bahasa agama daripada penghujahan falsafah. Kepentingan bahasa agama sebagai cabang falsafah agama dalam falsafah Melayu kontemporari dapat ditingkatkan, bukan hanya dengan mengharmonikan kepentingan falsafah dalam agama dan bahasa, tetapi juga memperbetulkan salah faham tentang falsafah, termasuk memperkasa kursus falsafah sedia ada sebagai kursus teras pada peringkat pengajian tinggi.

Negeri-negeri Melayu sering dilihat oleh sarjana pentadbir kolonial tidak mempunyai suatu sistem politik yang sistematik sebelum kedatangan Barat manakala aspek undang-undangnya pula dilihat kejam dan dianggap tidak perlu diberi perhatian serius oleh pembaca. Walhal kewujudan undang-undang tradisional seperti Undang-undang Kedah yang telah disusun sekurang-kurangnya sejak kurun ke-17 membuktikan sebaliknya. Artikel ini bertujuan meneliti idea dan pemikiran pemerintah Kedah tentang perancangan pembangunan ekonomi seperti yang terpancar dalam teks Undang-undang Kedah naskhah Ku Din Ku Meh (1893). Kajian ini menggunakan kaedah kualitatif yang melibatkan analisis terhadap fasal-fasal yang terkandung dalam teks tersebut bagi mengenal pasti idea, konsep dan pemikiran tentang pentadbiran negeri khususnya yang berkait dengan ekonomi. Berdasarkan kajian terhadap teks Undang-undang Kedah naskhah Ku Din Ku Meh ini didapati bahawa Kedah telah pun mempunyai satu sistem perundangan yang tersusun demi memanfaatkan transisi ekonomi yang dilaluinya sejak kurun ke-13 hingga kurun ke-17 yang akhirnya membolehkan Kedah beralih daripada sebuah kerajaan pelabuhan kepada agraria atau pertanian.

It is crucial to measure the heart rate of a person since it is one of the most significant physiological parameters and a key indication of peoples physiological states. The costly and intricate sensor and sensor system applications are frequently used in heart rate monitoring. Research that has advanced over the past ten years has focused increasingly on noncontact technologies that are easy to use, inexpensive, and pleasant. The majority of noncontact based systems are still suitable for lab settings in offline situations, but they need to advance significantly before they can be used in real-time applications. The camera on a laptop computer is used in this study to demonstrate a real-time HR monitoring technique. By variations in face skin tone brought on by the blood circulation, the heart rate is measured. The color channels of video recordings have been subjected to three distinct signal the processing techniques, including the Fast Fourier Transform (FFT), Independent Component Analysis (ICA), and the Principal Component Analysis (PCA), and the blood volume pulse (BVP) is recovered from the face areas.

Fat embolism (FE) is defined as the presence of fat globules within the circulation [1]. Fat embolism is extremely common after trauma and occurs, to a variable extent, in the majority of patients suffering long bone or pelvic fractures [2]. In the majority of patients, fat emboli appear to have minimal physiological effects and most patients display no signs or symptoms. Fat embolism syndrome (FES) is a rare but potentially fatal consequence of FE resulting in a spectrum of end organ damage. Fat embolism syndrome was originally described by the symptomatic triad of respiratory distress, neurological impairment, and petechial rash [1]. Although first reported in humansby Zenker in 1862,the pathophysiology of FES remains incompletely understood. Despite an accumulating body of literature describing the occurrence of FES, there remains significant clinical uncertainty regarding its diagnosis, prevention, and management.

Background: Many molecular investigations have identified that the methylation status of the O-6-methylguanine-DNA methyl transferase (MGMT) gene promoter in patients with high grade glioma is associated with a improved prognosis and survival when treated with temozolamide (TMZ). Aims and Objective: The aim of the study was to find out the distribution of methylation status and imaging characteristics in patients with High Grade Gliomas. Method: The study included forty consecutive patients who presented with neurological symptoms and were subsequently diagnosed as having a primary brain tumour on conventional MRI scan. MR-perfusion imaging was performed to determine the grade of the tumor which was subsequently compared with histopathological grade of the tumor after brain biopsy. The biopsy or surgical specimens were further analysed for determining the MGMT promoter methylation status using Methylation-specific PCR (MSP). Results: The mean age of patients was 50.3 years in the methylated group and 49.1 years in the unmethylated group (p value = 0.671). Out of 40 patients, 18 had methylated MGMT promoters while 22 had unmethylated MGMT promoters. We found that ring-like enhancement was seen more frequently in the unmethylated tumours (72.7%) than in methylated ones (61.1%). The presence of T2 heterogeneous signal intensity was seen more in the methylated group (77.8%) than unmethylated group (68.2%). Severe necrosis (affecting >50% of the tumour) was seen more in the methylated tumours (61.1%) than in the unmethylated tumours (40.09%). However, these differences were found to be statistically insignificant. Conclusion: The distribution and imaging characteristics may provide some information about methylation of high-grade gliomas but a multicentric large data maybe required to reach a consensus about its reliability when biopsy of the methylation status of the tumour is not available.

Objective: To study the role of USG Doppler, CT renal angiography in evaluation of iatrogenic renal vascular injuries and to assess the effectiveness & safety of endovascular intervention of Iatrogenic Renal Vascular Injuries (IRVIs). Materials and methods: A total of 23 patients with IRVIs were initially evaluated with USG Doppler followed by CT angiography and DSA was performed in 20 patients. Four out of 23 patients showed spontaneous resolution as confirmed by preprocedural USG Doppler. Endovascular embolization of IRVIs was performed using micro coils in 19 patients. Technical success was confirmed at the end of the procedure by a renal angiogram. The patients were followed up for a period of 6 months to assess the clinical success. Results: The most common cause of IRVI in our study was PCNL seen in 16(70%) patients followed by Partial Nephrectomy and PCN. All patients presented to us within 10-14 days of the etiological event with hematuria flank pain or drop in hematocrit. USG was able to detect IRVIs in the form of RAPs in 17(74%) and perirenal/intrarenal hematoma in 2(7%) cases. CT angiography was able to detect IRVIs in all the patients, however, additional aneurysms in two patients were not detected which were later seen on DSA renal angiography. Embolization was performed for 21 aneurysms in 19 patients using micro coils and showed 100 % technical and clinical success. Conclusion: USG Doppler and CT angiography play a very important role in diagnosis of iatrogenic renal vascular injuries. Endovascular embolization is an effective and safe method for management of injuries.

Retinitis pigmentosa (RP) is a group of hereditary illnesses characterized by a slow loss of retinal photoreceptors, which impairs a long-term vision. It is among the most prevalent forms of hereditary retinal dystrophy and has a sizable cost impact on both the individuals affected and the community as a whole. The typical symptoms of this disorder include nyctalopia, loss of the concentric visual field, and finally loss of the bilateral central vision.The primary effect is a progressive loss of vision. One of the main causes of vision loss and blindness in persons under 60, it affects roughly 1.5 million people globally. There is presently no known cure for RP, and the only approved gene therapy, voretigeneneparvovec, is only given to a tiny subset of patients with known RPE65 mutations. Retinoids, vitamin A supplements, sun protection, visual aids, and medical and surgical treatments to treat ocular comorbidities are now the only available therapies, however these merely serve to halt the diseases progression. Given the limited therapeutic landscape, it is vital to develop fresh, personalized therapy modalities that focus on degeneration of the retina. Although the variety of the gene mutations involved makes it difficult to identify a target treatment for RP, new fundamental research indicates an improvement towards comprehending the causes of retinal degeneration. Discovering novel molecular treatments that can specifically target specific receptors or signaling pathways lays the foundation for more effective medication development. The most recent advancements in potential RP treatments are highlighted in this article, with an emphasis on preclinical stage foundational research on molecular targets, which will form the basis for subsequent drug development. We will discuss the alterations that take place to the molecular pathways connected to the growth of RP, with a focus on the ER stress and apoptotic pathways, redox balance maintenance, and genomic stability. Subsequently proceed over the treatment modalities being looked at, like gene and cell therapy, as well as the most recent studies that are discovering new potential drug targets for RP.

In recent years, there has been an increase in worry about the presence of false news on the internet. Real and false news have becoming harder to identify as social media and other online platforms have rapidly replaced print media as many peoples major news sources. Techniques for natural language processing (NLP) have been developed to help identify and categorize bogus news in attempt to solve this problem. Examining the language used in news items is one method of spotting false information. Large datasets of news stories may be used to train NLP models to find linguistic patterns that are suggestive of false news. For instance, false news stories may employ dramatic or exaggerated language, or they may not cite reliable sources to back up their assertions. NLP models may be trained to recognize these patterns and spot news stories that are probably fraudulent by utilizing machine learning methods. One other method for spotting false news is to examine the social environment in which news pieces are circulated. The sharing and consumption of news stories by users is extensively documented by social media companies. NLP algorithms can spot stories that are probably false by looking for trends in social media activity. A sign that a news story is phony can be, for instance, if it is being shared quickly by a lot of bot accounts. Having access to good training data is crucial for developing an NLP-based false news detector. Real and false news stories should also be included in this data, along with information on how the pieces were shared and read on social media. Researchers may create algorithms that can precisely distinguish between real and false news stories by training NLP models on this data. Overall, the development of NLP algorithms for false news identification is a crucial milestone in the fight against the spread of untruth on the internet. We can create tools that assist individuals identify between true and false news and, in turn, foster a more informed and involved society by utilizing the power of machine learning and natural language processing.
KEY THEMES AND TRENDS IN RESEARCH ON BLACK GIRL LEADERSHIP: SYSTEMATIC REVIEW
Authors: S. Hurt Carletta , Reddick Nia
Published: May 2023

This systematic review is critical as it sheds light on a neglected area of research: the experiences of Black girls in leadership positions. While there is a growing body of literature on leadership and gender, race, and ethnicity, the experiences of Black girls in leadership roles have received less attention. This study addresses this gap in the literature by conducting a comprehensive analysis of research on Black girl leadership from 2000 to 2020.The problem that this systematic review address is the longstanding neglect of the experiences of Black girls in leadership positions. Despite the growing attention to issues of diversity and inclusion in leadership, the experiences of Black girls have been consistently overlooked and understudied.A systematic search was conducted in ERIC (Education Resources Information Center), Scopus and Google Scholar for articles published from 2000 to December 2020. The reference lists of the included studies were also searched to retrieve possible additional studies.The systematic review analyzed 9 articles and found six main themes in Black girl leadership: mentoring, oppression, intersectionality, underrepresentation, support networks, and the role of race. Each theme provided valuable insights into the experiences, challenges, and potentials of Black girls in leadership roles.The findings of this systematic review have important implications for researchers, policymakers, and educators working to promote equity and inclusion in leadership. Policymakers and educators can use this information to develop targeted interventions and programs to support Black girls in leadership positions.

One-Way ANOVA was used to analyze Likert-style data and explore the perceptions of completing a human resource capital management course. A thematic qualitative analysis was also used to identify and analyze themes within qualitative data. The findings revealed that respondents shared the same desire to complete a human capital management course, principals with varying degrees of experience perceived their masters degree in educational leadership as preparing them for the post of principal in the same way, and principals must believe they have the relevant knowledge and skillsto help them perceive that they are operating as efficient and effective human capital managers.
Performance assessment of bias correction methods using observed and regional climate model data in different watersheds, Ethiopia
Authors: Daniel Habtamu
Published: May 2023

Bias correction methods are used to compensate for any tendency to overestimate or underestimate the downscaled variables. Rainfall, maximum, and minimum temperatures are the key climate variables where the socioeconomic activities of the regions are principally based on rain-fed agriculture. This paper compares the performance of regional climate models (RCMs) and bias correction methods in Gelana and Deme watersheds in Ethiopia during the base period of 1988–2019. Observed data obtained from the Ethiopian National Meteorological Agency were used for performance evaluation of the RCM outputs. The performance of the three selected RCMs and four bias correction methods were evaluated by using four statistical indicators: Pearson correlation coefficient (R), root mean square error, Nash–Sutcliffe efficiency, and percent bias. The results show that the RACMO22T and HIRHAM5 models performed better than the RCA4 model in reproducing daily precipitation, and maximum and minimum temperatures in the Deme and Gelana watersheds. Similarly, the empirical quantile mapping method for precipitation and maximum temperature bias correction, and the distribution mapping method for minimum temperature bias correction, were well performed and preferable to adjust the climate variables of the future periods in these watersheds. Moreover, all RCMs performed better in the Deme watershed than in the Gelana watershed.

Esse artigo aborda a necessidade de promover a acessibilidade espacial a partir da relação entre o wayfinding e a sinalização dos espaços, e objetiva correlacionar esses na promoção da acessibilidade espacial. Para tanto, foi realizado um levantamento teórico-referencial que serviu como base para o desenvolvimento do estudo. A partir da revisão de literatura foi possível identificar os principais autores relacionados aos conceitos e adotou-se como estrutura metodológica, um esquema comparativo entre os conceitos estudados e os pilares da acessibilidade. Destaca-se a necessidade de discutir a temática de acessibilidade além das normativas existentes e sua relevância para a orientação das pessoas, considerando suas especificidades. Como resultado, o artigo evidencia a importância de se estruturar um sistema de wayfinding e de exploração das informações por ele proporcionadas, a fim de promover autonomia, segurança e conforto para todas as pessoas, independentemente de suas condições.
SETD1A-mediated Methylation of H3K4me3 Inhibits Ferroptosis in
Non-small Cell Lung Cancer by Regulating the WTAPP1/WTAP Axis
Authors: Wang Dao , Zu Yukun , Sun Wei , Fan Xiaowu
Published: May 2023

Introduction:

SETD1A is upregulated in non-small cell lung cancer (NSCLC)
tissues. This study investigated the molecular mechanism of the SETD1A/WTAPP1/WTAP
axis in NSCLC.

Methods:

Ferroptosis is a unique cell death mode driven by iron-reliant phospholipid peroxidation,
which is regulated by multiple cellular metabolic pathways, including REDOX
homeostasis, iron metabolism, mitochondrial activity and metabolism of amino
acids, lipids and sugars. Thus, the levels of ferroptosis markers (MDA, SOD, GSH) were
measured in vitro, and NSCLC cell behaviors were assessed. SETD1A-mediated
H3K4me3 methylation was analyzed. SETD1A-exerted effects on ferroptosis and tumor
growth in vivo were verified in nude mouse models.

Results:

SETD1A was highly expressed in NSCLC cells. Silencing SETD1A suppressed
NSCLC cell proliferation and migration, inhibited MDA, and enhanced GPX4, SOD, and
GSH levels. SETD1A elevated WTAP expression through WTAPP1 upregulation by mediating
H3K4me3 methylation in the WTAPP1 promoter region. WTAPP1 overexpression
partly averted the promotional effect of silencing SETD1A on NSCLC cell ferroptosis.
WTAP interference abrogated the inhibitory effects of WTAPP1 on NSCLC cell ferroptosis.
Silencing SETD1A facilitated ferroptosis and accelerated tumor growth in nude
mice through the WTAPP1/WTAP axis.

Conclusion:

SETD1A amplified WTAP expression through WTAPP1 upregulation by
mediating H3K4me3 modification in the WTAPP1 promoter region, thus promoting NSCLC
cell proliferation and migration and inhibiting ferroptosis.
Local Anesthetics, Clinical Uses, and Toxicity: Recognition and Management
Authors: Ozbay Sedat , Ayan Mustafa , Karcioglu Ozgur
Published: May 2023

Local anesthetic (LA) compounds decrease the permeability of the ion channels to sodium, which in
turn, reduces the rate of depolarization. These agents (a.k.a. -caines) are also used to depress mucosal sensations,
e.g., gag reflex in the form of topical anesthetics. Overdose of LA can lead to local anesthetic systemic
toxicity (LAST), which is the precursor of potentially lethal consequences on clinical grounds. There is a wide
array of possible presentations of LAST, from mild findings, such as temporary hypertensive events, to serious
conditions, including refractory cardiac dysfunction, dysrhythmias and prearrest situations. Lidocaine, prilocaine,
mepivacaine, ropivacaine, and bupivacaine are among the most commonly used members of the family.
The agents’ dosages should be adjusted in children, elderly and fragile individuals and those with organ failures,
as the metabolism of the compounds will be impaired. The ideal body weight, along with hepatic and renal
functional reserves, will have an impact on elimination kinetics. Systemic absorption is an untoward consequence
of LA administration which deserves every means of prevention. Intravenous lipid emulsion is an important
life-saving treatment in severe, life-threatening cases. This narrative review article is designed to cover the
clinical uses of LA in children, recognition, and management of untoward effects of the agents, with special emphasis
on the LAST.
High-throughput Second-generation Sequencing Technology Assisted
Diagnosis of Familial Partial Lipodystrophy (Type 2 Kobberling-Dunnigan
Syndrome): A Case Report
Authors: Deng Mingling , Chen Wen , Qi Yan
Published: May 2023

Background:

Whole exome sequencing (WES) provides support for clinical diagnosis
and treatment of genetically related diseases based on specific probe capture and high-throughput
second-generation sequencing technology. Familial partial lipodystrophy 2 (FPLD2; OMIM #
151660) or type 2 Köbberling-Dunnigan syndrome with insulin resistance syndrome is uncommon
in mainland China and elsewhere.

Aims:

We report the case in order to have a further understanding of FPLD2 or type 2 Kobberling-
Dunnigan syndrome) with the assistance of WES and improve the clinical and genetic understanding
and diagnosis of this disease.

Case Report:

A 30-year-old woman was admitted to the cadre department of our hospital at 14:00
on July 11, 2021, because of hyperglycemia, a rapid heart rate, and excessive sweating during
pregnancy. An oral glucose tolerance test (OGTT) showed that insulin and C-peptide increased
slowly after glucose stimulation, and the peak value was extended backward (Table 1). It was suggested
that the patient had developed insulin antibodies, resulting in insulin resistance. Her clinical
features and familial inheritance were consistent with FPLD2 (type 2 Kobberling-Dunnigan syndrome).
The results of WES indicated that a heterozygous mutation occurred in exon 8 of the
LMNA gene, because the base C at position 1444 was mutated into T during transcription. This mutation
changed the amino acid position 482 of the encoded protein from Arg to Trp. Type 2 Kobberling-
Dunnigan syndrome is associated with an LMNA gene mutation. According to the patient's
clinical manifestations, hypoglycemic and lipid-lowering therapy is recommended.

Conclusion:

WES can assist in the simultaneous clinical investigation or confirmation of FPLD2
and help identify diseases with similar clinical phenotypes. This case demonstrates that familial
partial lipodystrophy is associated with an LMNA gene mutation on chromosome 1q21-22. This is
one of the few cases of familial partial lipodystrophy diagnosed by WES.
Nanocarrier Mediated Intranasal Drug Delivery Systems for the Management
of Parkinsonism: A Review
Authors: Kapoor Archita , Hafeez Abdul , Kushwaha Poonam
Published: May 2023

The transport of drugs to the brain becomes a key concern when treating disorders of the
central nervous system. Parkinsonism is one of the major concerns across the world populations, which
causes difficulty in coordination and balance. However, the blood-brain barrier is a significant barrier to
achieving optimal brain concentration through oral, transdermal, and intravenous routes of administration.
The intranasal route with nanocarrier-based formulations has shown potential for managing Parkinsonism
disorder (PD). Direct delivery to the brain through the intranasal route is possible via the
olfactory and trigeminal pathways using drug-loaded nanotechnology-based drug delivery systems. The
critical analysis of reported works demonstrates dose reduction, brain targeting, safety, effectiveness,
and stability for drug-loaded nanocarriers. The important aspects of intranasal drug delivery, PD details,
and nanocarrier-based intranasal formulations in PD management with a discussion of physicochemical
characteristics, cell line studies, and animal studies are the major topics in this review. Patent reports
and clinical investigations are summarized in the last sections.

Reconstruction
Authors: Kang Hyo-Jin , Lee Jeong Min , Park Sae Jin , Lee Sang Min , Joo Ijin , Yoon Jeong Hee
Published: May 2023

Background:

Whether deep learning-based CT reconstruction could improve lesion conspicuity on abdominal CT when the radiation dose is reduced is controversial.

Objectives:

To determine whether DLIR can provide better image quality and reduce radiation dose in contrast-enhanced abdominal CT compared with the second generation of adaptive statistical iterative reconstruction [ASiR-V].

Aims:

This study aims to determine whether deep-learning image reconstruction [DLIR] can improve image quality.

Methods:

In this retrospective study, a total of 102 patients were included, who underwent abdominal CT using a DLIR-equipped 256-row scanner and routine CT of the same protocol on the same vendor's 64-row scanner within four months. The CT data from the 256-row scanner were reconstructed into ASiR-V with three blending levels [AV30, AV60, and AV100], and DLIR images with three strength levels [DLIR-L, DLIR-M, and DLIR-H]. The routine CT data were reconstructed into AV30, AV60, and AV100. The contrast-to-noise ratio [CNR] of the liver, overall image quality, subjective noise, lesion conspicuity, and plasticity in the portal venous phase [PVP] of ASiR-V from both scanners and DLIR were compared.

Results:

The mean effective radiation dose of PVP of the 256-row scanner was significantly lower than that of the routine CT [6.3±2.0 mSv vs. 2.4±0.6 mSv; p< 0.001]. The mean CNR, image quality, subjective noise, and lesion conspicuity of ASiR-V images of the 256-row scanner were significantly lower than those of ASiR-V images at the same blending factor of routine CT, but significantly improved with DLIR algorithms. DLIR-H showed higher CNR, better image quality, and subjective noise than AV30 from routine CT, whereas plasticity was significantly better for AV30.

Conclusion:

DLIR can be used for improving image quality and reducing radiation dose in abdominal CT, compared with ASIR-V.
