Authors: Chen Ying-Yi , Lin Kuan-Hsun , Kuo Yen-Shou , Tsai Yuan-Ming , Huang Hsu-Kai , Huang Tsai-Wang
Published: October 2023

Objectives

Tyrosine kinase inhibitors (TKIs) are the primary therapeutic option for patients with advanced-stage epidermal growth factor receptor-mutant (EGFR-m) lung adenocarcinoma. However, the role of EGFR-TKIs in advanced-stage lung cancer is uncertain regardless of therapeutic methods. This study investigated the outcome of the impact of epidermal growth factor receptor (EGFR)-TKI in patients with advanced lung adenocarcinoma treated with various therapeutic strategies.

Methods

This retrospective analysis used cancer registry data from 1159 patients with lung cancer treated between January 2015 and December 2017 at Tri-Service General Hospital. Only patients with lung adenocarcinoma stages 3B and four were selected for the study. All lung adenocarcinoma patients with ever TKI treatment had an EGFR mutation.

Results

Three-hundred sixty-two patients with advanced lung adenocarcinoma with complete medical records were enrolled. According to personalized therapeutic processes, they were divided into nine groups: only TKI treatment, only chemotherapy (CT), TKI with lung cancer salvage surgery, TKI with CT, TKI with radiotherapy (RT), CT with lung cancer salvage surgery, CT with RT, TKI with CT, and lung cancer salvage surgery. A multivariate Cox regression analysis showed TKI with lung cancer salvage surgery (HR: 4.675, p = 0.005) is the only good prognostic treatment. The poor predictors for overall survival were only CT (HR: 0.336, p = 0.048) and TKI with CT (HR: 0.359, p = 0.023). Kaplan–Meier survival analysis showed a statistical significance in an average overall survival (OS) of ever TKI treatment and never TKI treatment (33.24 vs. 17.64 months, p < 0.001). Furthermore, TKI usage duration was statistically increased in TKI with lung cancer salvage surgery (40.4 ± 20.7 vs 14.96 ± 13.13 months, p < 0.001). The survival rate (p = 0.033) and OS (p < 0.001) in lung cancer salvage surgery were statistically better than the group of TKI without surgery.

Conclusion

The best therapeutic strategy for advanced lung adenocarcinoma is TKI with lung cancer salvage surgery, according to significantly longer OS and better survival. It also prolonged TKI usage. Mutated EGFR lung adenocarcinoma patients with ever TKI treatment had significantly better survival than with other treatments. Regardless of the combination of other treatments, EGFR mutation with TKI therapy is recommended as a positive prognostic factor for patients with lung adenocarcinoma.

Published: October 2023

Background

Genetic variants of outer dynein arm docking complex subunit 2 (ODAD2) have been reported to be closely associated with primary ciliary dyskinesia and colorectal cancer in previous studies, but the association of genetic variants of ODAD2 with hepatocellular carcinoma (HCC) has not been reported.

Methods

We enrolled 80 healthy subjects and 468 Guangxi hepatitis B virus (HBV)-related HCC patients in this study. A case–control study method was used to explore the association of different ODAD2-rs7893462 genotypes with hepatocarcinogenesis. A comprehensive survival analysis was used to explore the association of rs7893462 with the prognosis of HBV-related HCC in Guangxi.

Results

Through a case–control study, we observed that patients carrying the G allele of rs7893462 had a markedly increased susceptibility to hepatocarcinogenesis (odds ratio = 1.712, 95% confidence interval = 1.032–2.839, P = 0.037). We found that there were significant prognosis differences among three different genotypes of rs7893462. Nomogram analysis suggested that the contribution of rs7893462 polymorphisms to the prognosis of HBV-related HCC was second only to the BCLC stage. Stratified survival analysis suggested that the AG genotype of rs7893462 was an independent prognostic risk factor for HBV-related HCC. Joint effect survival analysis also observed that the AG genotype of rs7893462 combined with clinical parameters could significantly identify HBV-related HCC patients with different prognostic outcomes more accurately, and the AG genotype was also observed to be independent of clinical factors in HBV-related HCC survival.

Conclusion

The ODAD2-rs7893462 polymorphisms can be used as an independent prognostic indicator of HBV-related HCC overall survival and are significantly associated with susceptibility to hepatocarcinogenesis.
Identify GADD45G as a potential target of 4-methoxydalbergione in treatment of liver cancer: bioinformatics analysis and in vivo experiment
Authors: Zeng Li-Ping , Qin Yu-Qi , Lu Xiao-Min , Feng Zhen-Bo , Fang Xian-Lei
Published: October 2023

Background

The growth arrest and DNA damage-inducible gene gamma (GADD45G), an important member of GADD45 family, has been connected to the development of certain human cancers. Our previous studies have confirmed that GADD45G expression could be upregulated by 4-methoxydalbergione (4MOD) in liver cancer cells, but its potential pathological role in hepatocellular carcinoma (HCC) has not been fully understood. This study aimed to determine potential role of GADD45G in HCC, and the effects of 4-methoxydalbergione (4MOD) on the regulation of GADD45G expression in vivo were also analyzed.

Methods

Publicly available data and in-house immunohistochemistry (IHC) experiments were utilized to explore the expression profiles and clinical significance of GADD45G in HCC samples. Functional enrichment analysis based on GADD45G co-expression genes was used to excavate the molecular mechanism of GADD45G in HCC. We also conducted in vivo experiment on BALB/c nude mice to excavate the inhibitory effect of 4MOD on HCC and to evaluate the differences in the expression of GADD45G in xenograft tissues between the 4MOD-treated and untreated groups.

Results

GADD45G displayed significant low expression in HCC tissues. Downregulated expression of GADD45G was positively correlated with some high risk factors in HCC patients and predicted worse prognosis of HCC patients. There was a close association of GADD45G mRNA expression and immune cells, including neutrophils, NK cells, CD8 T cells, and macrophages. Co-expressed genes of GADD45G were involved in several pathways including cell cycle, carbon metabolism, and peroxisome. 4MOD could significantly suppress the growth of HCC in vivo, and this inhibitory effect was dependent on the upregulation of GADD45G expression.

Conclusion

GADD45G expression can be used as a new clinical biomarker for HCC and GADD45G may be a potential target for the anti-cancer effect of 4MOD in liver cancer.
Issues in the surgical management of skin squamous cell cancers in albinos—experience of two surgical oncology units in Burkina Faso
Authors: Zongo Nayi , Djiguemde Adeline R. , Yameogo Parateyandé Bonaventure , Bagué Abdoul Halim , Ka Sidy , Traoré Bangaly , Pascal Niamba , Dem Ahmadou
Published: October 2023

Background and objectives

Skin cancers in albinos are frequent in sunny countries. The surgeon plays a crucial role in their treatment. The objective was to describe the challenges of surgical management of skin cancer in albinos.

Methods

Retrospective, descriptive, and multicenter study on skin cancer surgery in albinos performed over the past 14 years in Ouagadougou. We were interested in surgery indications, techniques, and results. Survival was assessed using the Kaplan–Meier method. Comparisons of proportions were made by Student’s t-test.

Results

The cancers were multiple synchronous in 41.3%. We identified 46 albinos with 71 skin cancers. Surgery was performed in 93%. Lesions were located on the back, upper limbs, and head and face in 40.9%, 30.3%, and 16.7%, respectively. Precancerous lesions were treated concomitantly in 23.6%. The surgery consisted of a lumpectomy. Direct suturing and mobilization of flaps allowed skin coverage in 17.9% and 34.3%, respectively. Lymph node dissection was associated with the limbs in 73.1% of localizations. The average number of lymph nodes removed was 11, with extremes of 7 and 14. Node invasion was noted in 16 out of 19 cases. The resection margins were invaded in 7.5% and required surgical revision. Recurrences were noted in 8.9% of cases. Overall 2-year survival rate was 55.8%.

Conclusions

Surgery must meet the triple challenge of treating single or multiple synchronous cancers, precancerous lesions, and allowing good healing. Early diagnosis would reduce the rate of secondary healing and improve survival. The absence of extemporaneous histology and the large size of the tumors associated with the delay in diagnosis meant that surgery, whenever possible, was limited to wide and deep resection, to ensure healthy margins.
The serum lipid profiles in immune thrombocytopenia: Mendelian randomization analysis and a retrospective study
Authors: Xu Pengcheng , Han Shouqing , Hou Ming , Zhao Yajing , Xu Miao
Published: October 2023

Background

Immune thrombocytopenia (ITP) is an autoimmune hemorrhagic disease characterized by increased platelet destruction and impaired thrombopoiesis. The changes in platelet indices depend on the morphology and volume of platelets. Serum lipids have been found to affect platelet formation and activity in certain diseases, thus inducing the corresponding variation of platelet indices.

Methods

Mendelian randomization (MR) analysis was performed based on databases. The clinical data from 457 ITP patients were retrospectively collected and analyzed, including platelet indices, serum lipids, hemorrhages and therapeutic responses.

Results

MR analysis showed low high-density-lipoprotein-cholesterol (HDL-C), low apolipoprotein A-1, high triglyceride (TG) and high apolipoprotein B (ApoB) caused high platelet distribution width (PDW); high low-density-lipoprotein-cholesterol (LDL-C) increased mean platelet volume (MPV). In ITP, there were positive correlations between platelet count with TG, PDW with HDL-C and ApoB, and plateletcrit with TG and non-esterified fatty acid, and the correlation had gender differences. Bleeding scores were negatively correlated with cholesterol and LDL-C. LDL-C and homocysteine were risk factors for therapeutic responses.

Conclusions

Serum lipids, especially cholesterol were tightly correlated with platelet indices, hemorrhage and therapeutic effects in ITP patients. These results provide clinical references for the management of serum lipids, and highlight the necessity to further explore the relationship between lipids and pathogenesis of ITP.

Authors: Yusoff Hanizah Mohd , Ahmad Hanis , Ismail Halim , Reffin Naiemy , Chan David , Kusnin Faridah , Bahari Nazaruddin , Baharudin Hafiz , Aris Azila , Shen Huam Zhe , Rahman Maisarah Abdul
Published: October 2023

Violence against healthcare workers recently became a growing public health concern and has been intensively investigated, particularly in the tertiary setting. Nevertheless, little is known of workplace violence against healthcare workers in the primary setting. Given the nature of primary healthcare, which delivers essential healthcare services to the community, many primary healthcare workers are vulnerable to violent events. Since the Alma-Ata Declaration of 1978, the number of epidemiological studies on workplace violence against primary healthcare workers has increased globally. Nevertheless, a comprehensive review summarising the significant results from previous studies has not been published. Thus, this systematic review was conducted to collect and analyse recent evidence from previous workplace violence studies in primary healthcare settings. Eligible articles published in 2013–2023 were searched from the Web of Science, Scopus, and PubMed literature databases. Of 23 included studies, 16 were quantitative, four were qualitative, and three were mixed method. The extracted information was analysed and grouped into four main themes: prevalence and typology, predisposing factors, implications, and coping mechanisms or preventive measures. The prevalence of violence ranged from 45.6% to 90%. The most commonly reported form of violence was verbal abuse (46.9–90.3%), while the least commonly reported was sexual assault (2–17%). Most primary healthcare workers were at higher risk of patient- and family-perpetrated violence (Type II). Three sub-themes of predisposing factors were identified: individual factors (victims’ and perpetrators’ characteristics), community or geographical factors, and workplace factors. There were considerable negative consequences of violence on both the victims and organisations. Under-reporting remained the key issue, which was mainly due to the negative perception of the effectiveness of existing workplace policies for managing violence. Workplace violence is a complex issue that indicates a need for more serious consideration of a resolution on par with that in other healthcare settings. Several research gaps and limitations require additional rigorous analytical and interventional research. Information pertaining to violent events must be comprehensively collected to delineate the complete scope of the issue and formulate prevention strategies based on potentially modifiable risk factors to minimise the negative implications caused by workplace violence.
A single-center study of clinical features of pediatric Sjögren’s syndrome
Authors: Hou Ling , Wang Ningning , Zhao Chengguang , Wang Xiuli , Du Yue
Published: October 2023

Objective

Sjögren’s syndrome (SS) is a rare disease with unclear diagnostic criteria among the children and adolescents. The purpose of this study is to describe the clinical features of pediatric Sjögren’s syndrome and validate with Japanese diagnostic guidelines criteria of 2018.

Methods

We conducted a retrospective analysis of the clinical data of a cohort of 54 patients with pediatric Sjögren’s syndrome admitted to our hospital over a total of 10 years from September 2013 to September 2022.

Results

The ratio of females to males was 49:5 among the 54 children (34 cases of primary SS and 20 cases of secondary SS), the average age of onset of symptoms for the first time was 9.9 years, and the average age at diagnosis was 10.2 years. In terms of subjective symptoms, 7 cases (13.0%) presented with dry mouth and 5 cases (9.3%) reported dry eyes. The positive rates were 9.3% for Schirmer I test, 70.4% for salivary gland function test, and 55.6% for salivary gland ultrasonography. The positive rates were 94.4% for Anti-Ro/SSA antibodies, 66.7% for Anti-La/SSB antibodies, 88.9% for ANA, 59.3% for RF, and the elevation rate of IgG was 63.0%. Among the EULAR Sjögren’s syndrome disease activity index (ESSDAI) domains, the biological, constitutional, glandular, cutaneous, and lymphadenopathy domains were most involved. Treatment consisted of glucocorticoids in 88.9% of the patients in our study and hydroxychloroquine in 92.6%. As per the Japanese version of the clinical practice guidance for Sjögren’s Syndrome in pediatric patients (2018), 5 cases were identified as Definite SS, 35 cases as Probable SS, and 14 cases as Possible SS. With respect to primary and secondary SS, there was essentially no significant difference between the groups in any of the above aspects.

Conclusions

Patients with pediatric SS presented with a wide spectrum of clinical features, a low prevalence of reported symptoms of dry mouth and dry eyes, and various clinical manifestations with multi-system involvement. These are similar to other pediatric study cohorts in terms of epidemiology, auxiliary investigation results, disease activity scores, and treatment. The coincidence between our study and the Japanese version of the clinical practice guidance for Sjögren’s Syndrome in pediatric patients (2018) is good for the diagnosis of pediatric SS.

Published: October 2023

The mosquito-borne flaviviruses West Nile virus (WNV) and Usutu virus (USUV) pose a significant threat to the health of humans and animals. Both viruses co-circulate in numerous European countries including Germany. Due to their overlapping host and vector ranges, there is a high risk of co-infections. However, it is largely unknown if WNV and USUV interact and how this might influence their epidemiology. Therefore, in-vitro infection experiments in mammalian (Vero B4), goose (GN-R) and mosquito cell lines (C6/36, CT) were performed to investigate potential effects of co-infections in vectors and vertebrate hosts. The growth kinetics of German and other European WNV and USUV strains were determined and compared. Subsequently, simultaneous co-infections were performed with selected WNV and USUV strains. The results show that the growth of USUV was suppressed by WNV in all cell lines. This effect was independent of the virus lineage but depended on the set WNV titre. The replication of WNV also decreased in co-infection scenarios on vertebrate cells. Overall, co-infections might lead to a decreased growth of USUV in mosquitoes and of both viruses in vertebrate hosts. These interactions can strongly affect the epidemiology of USUV and WNV in areas where they co-circulate.
Neocortex neurogenesis and maturation in the African greater cane rat
Authors: Mustapha Oluwaseun , Grochow Thomas , Olopade James , Fietz Simone A.
Published: October 2023

Background

Neocortex development has been extensively studied in altricial rodents such as mouse and rat. Identification of alternative animal models along the “altricial-precocial” spectrum in order to better model and understand neocortex development is warranted. The Greater cane rat (GCR, Thyronomys swinderianus) is an indigenous precocial African rodent. Although basic aspects of brain development in the GCR have been documented, detailed information on neocortex development including the occurrence and abundance of the distinct types of neural progenitor cells (NPCs) in the GCR are lacking.

Methods

GCR embryos and fetuses were obtained from timed pregnant dams between gestation days 50–140 and their neocortex was analyzed by immunofluorescence staining using characteristic marker proteins for NPCs, neurons and glia cells. Data were compared with existing data on closely related precocial and altricial species, i.e. guinea pig and dwarf rabbit.

Results

The primary sequence of neuro- and gliogenesis, and neuronal maturation is preserved in the prenatal GCR neocortex. We show that the GCR exhibits a relatively long period of cortical neurogenesis of 70 days. The subventricular zone becomes the major NPC pool during mid-end stages of neurogenesis with Pax6 + NPCs constituting the major basal progenitor subtype in the GCR neocortex. Whereas dendrite formation in the GCR cortical plate appears to initiate immediately after the onset of neurogenesis, major aspects of axon formation and maturation, and astrogenesis do not begin until mid-neurogenesis. Similar to the guinea pig, the GCR neocortex exhibits a high maturation status, containing neurons with well-developed dendrites and myelinated axons and astrocytes at birth, thus providing further evidence for the notion that a great proportion of neocortex growth and maturation in precocial mammals occurs before birth.

Conclusions

Together, this work has deepened our understanding of neocortex development of the GCR, of the timing and the cellular differences that regulate brain growth and development within the altricial–precocial spectrum and its suitability as a research model for neurodevelopmental studies. The timelines of brain development provided by this study may serve as empirical reference data and foundation in future studies in order to model and better understand neurodevelopment and associated alterations.
Assessment of subclinical left ventricular myocardial systolic dysfunction in type 2 diabetes mellitus patients with or without hypertension by global and segmental myocardial work
Authors: Li Guang-An , Huang Jun , Sheng Xiao , Fan Li
Published: October 2023

Objective

The research was aimed to evaluate the subclinical left ventricular (LV) myocardial systolic dysfunction in T2DM patients with or without hypertension (HT) by global and segmental myocardial work (MW).

Methods

A total of 120 T2DM patients (including 60 T2DM patients with HT) and 70 sex- and age- matched normal controls were included. The global and segmental variables of work index (WI), constrictive work (CW), waste work (WW), work efficiency (WE), and CW/WW were analysed by non-invasive pressure-strain loop. Receiver operating characteristic (ROC) analysis was performed for detection the subclinical LV systolic dysfunction in T2DM patients with and without HT.

Results

The global work index (GWI), global CW (GCW), global WE (GWE), and GCW/global WW (GWW) of T2DM and T2DM patients with HT were significantly lower than normal controls (p < 0.05). The WI, CW, WE, and CW/WW of the LV anterior wall in T2DM and T2DM patients with HT were significantly lower when compared with those of the normal controls (p < 0.05). ROC analysis showed that the value of area under the curve (AUC) in combined GWI, GCW, GWE, and GCW/GWW was significantly higher than the AUCs of the individual indices (p < 0.05).

Conclusions

MW can non-invasively and accurately evaluate subclinical global and segmental LV myocardial systolic dysfunction in T2DM patients with and without HT. Regulating total cholesterol levels and controlling blood pressure in T2DM patients with and without HT might reduce the impairment of LV myocardial systolic function.
Development of multi-target dsRNAs targeting PcNLP gene family to suppress Phytophthora capsici infection in Nicotiana benthamiana
Authors: Park Minsu , Kweon Yujin , Eom Jihyun , Oh Minsun , Shin Chanseok
Published: October 2023

Phytophthora capsici, which causes diseases in solanaceous crops, secretes necrosis and ethylene-inducing peptide 1-like proteins (NLPs) that induce plant defense responses and leaf necrosis. In this study, we used RNA interference (RNAi) technique, a proven strategy for crop protection and gene regulation in plants, to suppress P. capsici infection through the inhibition of PcNLPs. In the RNAi mechanism, Dicer processes double-stranded RNA (dsRNA) into smaller entities known as small interfering RNAs (siRNAs). These siRNAs subsequently integrate into the RNA-induced silencing complex to form sequence-specific base pairing with complementary regions of the target mRNA. This interaction effectively initiates the degradation process of the target mRNA. We designed and synthesized dsRNAs targeting the “AIMY” and “GHRHDWE” conserved motifs of PcNLP gene family, which are predicted to be key elements for the expression of NLPs and pathogen infection. After infiltration of dsRNAs targeting the motifs and inoculation with P. capsici, we confirmed a significant suppression of P. capsici infection and downregulation of the PcNLP gene family. These findings imply that the dsRNA-mediated RNAi technique holds potential for mitigating a wide range of pathogens, while simultaneously suppressing the expression of a particular gene family using dsRNA targeting functional conserved motifs in the gene family.

Published: October 2023

Background

Binge-eating disorder (BED) is the most common eating disorder phenotype and is linked to several negative health outcomes. Yet, little is known about the social epidemiology of BED, particularly in early adolescence. The objective of this study was to examine the associations between sociodemographic characteristics and BED and binge-eating behaviors in a large, national cohort of 10–14-year-old adolescents in the United States (U.S.)

Methods

We conducted a cross-sectional analysis of two-year follow-up data from the Adolescent Brain Cognitive Development (ABCD) Study (2018 − 2020) that included 10,197 early adolescents (10 − 14 years, mean 12 years) in the U.S. Multivariable logistic regression models were used to assess the associations between sociodemographic characteristics and BED and binge-eating behaviors, defined based on the Kiddie Schedule for Affective Disorders and Schizophrenia.

Results

In this early adolescent sample (48.8% female, 54.0% White, 19.8% Latino/Hispanic, 16.1% Black, 5.4% Asian, 3.2% Native American, 1.5% Other), the prevalence of BED and binge-eating behaviors were 1.0% and 6.3%, respectively. Identifying as gay or bisexual (compared to heterosexual; adjusted odds ratio [AOR]: 2.25, 95% CI 1.01–5.01) and having a household income of less than $75,000 (AOR: 2.05, 95% CI: 1.21–3.46) were associated with greater odds of BED. Being male (AOR: 1.28, 95% CI: 1.06–1.55), of Native American (AOR: 1.60, 95% CI: 1.01–2.55) descent, having a household income less than $75,000 (AOR: 1.34, 95% CI: 1.08–1.65), or identifying as gay or bisexual (AOR for ‘Yes’ Response: 1.95, 95% CI: 1.31–2.91 and AOR for ‘Maybe’ Response: 1.81, 95% CI: 1.19–2.76) were all associated with higher odds of binge-eating behaviors.

Conclusion

Several sociodemographic variables showed significant associations with binge-eating behaviors, which can inform targeted screening, prevention, and education campaigns for BED among early adolescents.

Published: October 2023

Background

Ethyl formate (EF) is naturally occurring volatile compound used as quarantine fumigant for pest control. Recently, conversion of uses of EF was tried from quarantine to agricultural field due to its promising efficacy. However, there is a lack of studies on the residue pattern on crops and soil and the phytotoxic mechanism of EF in greenhouse environment. This study aimed to evaluate the efficacy, residue analysis, and phytotoxicity of EF fumigation in controlling Myzus persicae and Thrips palmi, on cucurbit crops and establish an optimized fumigation strategy for use in greenhouses.

Results

The results showed that EF was more effective against M. persicae than against T. palmi. Residue analysis indicated that EF rapidly decomposed and was not retained after 30 min in leaves and 2 h in soil after fumigation, suggesting the potential for residue-free pest control. Phytotoxicity test revealed that watermelon was the most sensitive crop to EF, and H2O2 accumulation was observed above a concentration of 7.5 g/m3. A strategy to reduce phytotoxicity with sodium bicarbonate during fumigation showed promising results in reducing phytotoxic effects on the crops. The optimized EF fumigation with 6 g/m3 was applied in a greenhouse, resulting in 100% and 40% mortality of M. persicae and T. palmi, respectively, with no notable phytotoxicity and EF residue in the treated crops and soil.

Conclusion

This study demonstrates that optimized EF fumigation can be an environmentally sustainable method for controlling pests in greenhouses, paving the way for improved pest management practices and sustainable agriculture. Further research is needed to validate these findings and explore the potential of EF fumigation for other crops and pests.

Authors: Lê Khan , Heshmati Niusha , Mathur Sanjay
Published: October 2023

Light emitting diodes (LEDs) have become part of numerous electrical and electronic systems such as lighting, displays, status indicator lamps and wearable electronics. Owing to their excellent optoelectronic properties and deposition via simple solution process, metal halide perovskites possess unique potential for developing halide perovskite-based LEDs (PeLEDs) with superior photoluminescence efficiencies leading to external quantum efficiencies beyond 20% for PeLEDS. However, the limited durability, high operative voltages, and challenges of scale-up are persisting barriers in achieving required technology readiness levels. To build up the existing knowledge and raise the device performance this review provides a state-of-the-art study on the properties, film and device fabrication, efficiency, and stability of PeLEDs. In terms of commercialization, PeLEDs need to overcome materials and device challenges including stability, ion migration, phase segregation, and joule heating, which are discussed in this review. We hope, discussions about the strategies to overcome the stability issues and enhancement the materials intrinsic properties towards development more stable and efficient optoelectronic devices can pave the way for scalability and cost-effective production of PeLEDs.

Multifaceted functions of Drp1 in hypoxia/ischemia-induced mitochondrial quality imbalance: from regulatory mechanism to targeted therapeutic strategy
Authors: Hao Shuai , Huang He , Ma Rui-Yan , Zeng Xue , Duan Chen-Yang
Published: October 2023

Hypoxic-ischemic injury is a common pathological dysfunction in clinical settings. Mitochondria are sensitive organelles that are readily damaged following ischemia and hypoxia. Dynamin-related protein 1 (Drp1) regulates mitochondrial quality and cellular functions via its oligomeric changes and multiple modifications, which plays a role in mediating the induction of multiple organ damage during hypoxic-ischemic injury. However, there is active controversy and gaps in knowledge regarding the modification, protein interaction, and functions of Drp1, which both hinder and promote development of Drp1 as a novel therapeutic target. Here, we summarize recent findings on the oligomeric changes, modification types, and protein interactions of Drp1 in various hypoxic-ischemic diseases, as well as the Drp1-mediated regulation of mitochondrial quality and cell functions following ischemia and hypoxia. Additionally, potential clinical translation prospects for targeting Drp1 are discussed. This review provides new ideas and targets for proactive interventions on multiple organ damage induced by various hypoxic-ischemic diseases.

Published: October 2023

Background

Hyperlipidemia and oxidative stress is recognized as risk factor for several diseases such as COVID-19. The aim of this study was to evaluate the effect of oral administration of Mucuna milks on body weight gain, blood lipid levels and redox status in rat model fed high fat diet.

Methods

Mucuna milks were produced from two varieties of Mucuna seeds. Three controls (I, II, III) made of normal rats fed with standard diet, rats fed with high fat diet and rats fed with high fat diet submitted to oral administration of atorvastatin (10 mg/kg/day). In addition, four test groups (IV, V, VI, VII) made with rats fed high fat diet and received oral administration of 20 mL of vegetable milk per day (10 mL at morning and 10 mL at afternoon).

Results

Results confirmed that rats on the high fat diet only showed an increasing of about 224% of their initial body weight, abdominal fat and a significant (p < 0.05) increases of lipid peroxidation (MDA) in liver and heart after five weeks. However, oral administration of Mucuna milk inhibit weight gain by about 66% and abdominal fat (54.53–55.60%). The reduction of LDL, VLDL, Triglycerides and Total cholesterol was remarkable in groups of rat treated with vegetable milk, about 67% reduction for dehulled Mucuna milks (DCM, DVM) and 69% reduction for whole Mucuna milks (WCM, WVM). Hyperlipidemic group rats had higher ASAT (134.17 UI/L) and ALAT (101.72 UI/L) levels, but Mucuna milks improved the ASAT and ALAT levels in rats. The reduction of MDA (70 − 50%) was related to phenolic content of Mucuna milks. significant and negative correlations was observed between catalase and MDA (r= -0.86; p = 0.05); MDA and SOD (r = − 0.60; p = 0.05).

Conclusion

This study suggests that treatment with Mucuna milks have anti-hyperlipidemia properties and increased the activity of antioxidant enzymes.

Published: October 2023

Parkinson’s disease (PD) is a neurodegenerative disorder with motor deficits due to nigrostriatal dopamine depletion and with the non-motor/premotor symptoms (NMS) such as anxiety, cognitive dysfunction, depression, hyposmia, and sleep disorders. NMS is presented in at least one-fifth of the patients with PD. With the histological information being investigated, stem cells are shown to provide neurotrophic supports and cellular replacement in the damaging brain areas under PD conditions. Pathological change of progressive PD includes degeneration and loss of dopaminergic neurons in the substantia nigra of the midbrain. The current stem cell beneficial effect addresses dopamine boost for the striatal neurons and gliovascular mechanisms as competing for validated PD drug targets. In addition, there are clinical interventions for improving the patient’s NMS and targeting their autonomic dysfunction, dementia, mood disorders, or sleep problems. In our and many others’ research using brain injury models, multipotent mesenchymal stromal cells demonstrate an additional and unique ability to alleviate depressive-like behaviors, independent of an accelerated motor recovery. Intranasal delivery of the stem cells is discussed for it is extensively tested in rodent animal models of neurological and psychiatric disorders. In this review, we attempt to discuss the repairing potentials of transplanted cells into parkinsonism pathological regions of motor deficits and focus on preventive and treatment effects. From new approaches in the PD biological therapy, it is believed that it can as well benefit patients against PD-NMS.

The aim of the project was to develop a patient-specific stereotactic system that allows simultaneous and thus time-saving treatment of both cerebral hemispheres and that contains all spatial axes and can be used as a disposable product. Furthermore, the goal was to reduce the size and weight of the stereotactic system compared to conventional systems to keep the strain on the patient, who is awake during the operation, to a minimum. In addition, the currently mandatory computed tomography should be avoided in order not to expose the patient to harmful X-ray radiation as well as to eliminate errors in the fusion of CT and MRI data.

3D printing best meets the requirements in terms of size and weight: on the one hand, the use of plastic has considerable potential for weight reduction. On the other hand, the free choice of the individual components offers the possibility to optimize the size and shape of the stereotactic system and to adapt it to the individual circumstances while maintaining the same precision. The all-in-one stereotactic system was produced by means of the Multi Jet Fusion process. As a result, the components are highly precise, stable in use, lightweight and sterilizable. The number of individual components and interfaces, which in their interaction are potential sources of error, was significantly reduced. In addition, on-site manufacturing leads to faster availability of the system.

Within the project, a patient-specific stereotaxy system was developed, printed, and assembled, which enables the execution of deep brain stimulation via only three bone anchors located on the skull. Pre-developed MRI markers, which can be screwed directly onto the bone anchors via the sleeves, eliminate the need for a CT scan completely. The fusion of the data, which is no longer required, suggests an improvement in target accuracy.

Background

The corpus callosum (CC) is a key brain structure. In children with neurodevelopmental delay, we compared standard qualitative radiological assessments with an automatic quantitative tool.

Methods

We prospectively enrolled 73 children (46 males, 63.0%) with neurodevelopmental delay at single university hospital between September 2020 and September 2022. All of them underwent 1.5-T brain magnetic resonance imaging (MRI) including a magnetization-prepared 2 rapid acquisition gradient echoes − MP2RAGE sequence. Two radiologists blindly reviewed the images to classify qualitatively the CC into normal, hypoplasic, hyperplasic, and/or dysgenetic classes. An automatic tool (QuantiFIRE) was used to provide brain volumetry and T1 relaxometry automatically as well as deviations of those parameters compared with a healthy age-matched cohort. The MRI reference standard for CC volumetry was based on the Garel et al. study. Cohen κ statistics was used for interrater agreement. The radiologists and QuantiFIRE’s diagnostic accuracy were compared with the reference standard using the Delong test.

Results

The CC was normal in 42 cases (57.5%), hypoplastic in 20 cases (27.4%), and hypertrophic in 11 cases (15.1%). T1 relaxometry values were abnormal in 26 children (35.6%); either abnormally high (18 cases, 24.6%) or low (8 cases, 11.0%). The interrater Cohen κ coefficient was 0.91. The diagnostic accuracy of the QuantiFIRE prototype was higher than that of the radiologists for hypoplastic and normal CC (p = 0.003 for both subgroups, Delong test).

Conclusions

An automated volumetric and relaxometric assessment can assist the evaluation of brain structure such as the CC, particularly in the case of subtle abnormalities.

Relevance statement

Automated brain MRI segmentation combined with statistical comparison to normal volume and T1 relaxometry values can be a useful diagnostic support tool for radiologists.

Key points

• Corpus callosum abnormality detection is challenging but clinically relevant.

• Automated quantitative volumetric analysis had a higher diagnostic accuracy than that of visual appreciation of radiologists.

• Quantitative T1 relaxometric analysis might help characterizing corpus callosum better.

Placental perfusion imaging on 3Tesla magnetic resonance imaging using pseudo-continuous arterial spin labelling: an initial experience
Authors: Chandrasekhar Priyanka , Rangasami Rajeswaran , Andrew Chitra , Paarthipan N.
Published: October 2023

Background

During pregnancy, the placenta plays an important role in the development of the fetus by supplying it with oxygen and nutrition, eliminating waste, and acting as an immunological barrier. Pseudo-continuous arterial spin labelling (pCASL) MRI was recently shown to be a promising sequence for measuring perfusion in the placenta. The aim was to obtain the perfusion measurements of the placenta in normal pregnancies using 3 Tesla MRI from 19 to 38 weeks of gestational age.

Results

This was a cohort observational study. One hundred and sixty (160) singleton pregnancies from 19 to 38 weeks of gestational age were included. A 3D pCASL sequence was performed in the axial plane for placental blood flow (PBF). Data post-processing was performed on a workstation using Ready View software for 3D ASL with automated generation of quantitative placental pattern-based morphometry (PBM). The mean values of placental perfusion were extracted by averaging the data obtained. A significant positive correlation was observed between the PBF and increasing GA using Karl Pearson’s coefficient of correlation values (r-value 0.77, p-value < 0.001), respectively. Average PBF values from 19 to 38 weeks were (89.4 ± 13.5 to 155.3 ± 2.8 ml/100 g/min). According to our intra-class correlation coefficient (ICC), inter-observer reproducibility of placental blood flow shows good agreement between observers (0.98).

Conclusions

Normal PBF values using ASL in 3 T MRI from 19 to 38 weeks of gestational age were provided. Statistical analysis revealed a significant positive correlation between gestational age and placental blood flow. In the future, it may help to identify placental perfusion abnormalities like placental insufficiency, preeclampsia, and fetal growth restriction (FGR).
Case series of intraorbital colobomatous cysts with anophthalmos/microphthalmos spectrum: a rare diagnostic conundrum simplified
Authors: Ranga Anju , Yadav Renu , Bansal Neha , Gupta Jyoti , Bhayana Aanchal
Published: October 2023

Background

Anophthalmos/microphthalmos spectrum is a rare congenital eye disorder and concurrence of a cystic intraorbital lesion is even rarer. Every so often it presents as a diagnostic enigma for the clinician as well as radiologist. The occurrence of anomaly is linked with early intraembryonic insult and is closely linked with neuroectodermal development of the eyeball. There is a wide range of differential diagnoses for the intraaorbital cysts associated with microphthalmos cases ranging from colobomas to teratomas. The radiological findings in the coloboma gamut are poorly understood with a paucity of the literature regarding the same. Early and correct diagnosis is imperative for the proper management of the patient.

Case presentation

We present the radiological findings in three patients presenting at different ages with a basic approach pattern.

Conclusions

Knowledge of the radiological findings in cases of intraorbital colobomatous cysts and associations along with their embryological basis would help in making the correct diagnosis ensuing timely and accurate patient management.

Full degree-of-freedom polarization hologram by freeform exposure and inkjet printing

Published: October 2023

Since the invention of holography by Dennis Gabor, the fabrication of holograms has mainly relied on direct recording of wavefront by engraving the intensity fringes of interfering electric fields into the holographic material. The degree-of-freedom (DoF) is often limited, especially for its usage as a holographic optical element in imaging or display systems, as what is recorded is what to use. In this work, based on the emerging self-assembled photo-aligned liquid crystal, a polarization hologram with full DoF for local manipulation of optical structure is demonstrated. The ability to record an arbitrary wavefront (in-plane DoF) is achieved by freeform surface exposure, while the local adjustment of deposited liquid crystal (out-of-plane DoF) is realized by inkjet printing. The methodology for designing and fabricating such a hologram is exemplified by building a full-color retinal scanning display without color crosstalk. Here, the arbitrary wavefront modulation capability helps to eliminate the aberrations caused by mismatched exposure and display wavelengths. The local liquid crystal adjustment ability enables the suppression of crosstalk by variation of chiral pitch and film thickness to tune the peak and valley of Bragg diffraction band. The demonstrated method is expected to greatly impact the fields of advanced imaging and display, such as augmented reality and virtual reality, that require optics with an ultrathin form factor and high degrees of design freedom simultaneously.
