Long noncoding RNAs and mRNAs profiling in ovary during laying and broodiness in Taihe Black-Bone Silky Fowls (Gallus gallus Domesticus Brisson)
Authors: Tan Yuting , Huang Yunyan , Xu Chunhui , Huang Xuan , Li Shibao , Yin Zhaozheng
Published: April 2024

Background

Broodiness significantly impacts poultry egg production, particularly notable in specific breeds such as the black-boned Silky, characterized by pronounced broodiness. An understanding of the alterations in ovarian signaling is essential for elucidating the mechanisms that influence broodiness. However, comparative research on the characteristics of long non-coding RNAs (lncRNAs) in the ovaries of broody chickens (BC) and high egg-laying chickens (GC) remains scant. In this investigation, we employed RNA sequencing to assess the ovarian transcriptomes, which include both lncRNAs and mRNAs, in eight Taihe Black-Bone Silky Fowls (TBsf), categorized into broody and high egg-laying groups. This study aims to provide a clearer understanding of the genetic underpinnings associated with broodiness and egg production.

Results

We have identified a total of 16,444 mRNAs and 18,756 lncRNAs, of which 349 mRNAs and 651 lncRNAs exhibited significantly different expression (DE) between the BC and GC groups. Furthermore, we have identified the cis-regulated and trans-regulated target genes of differentially abundant lncRNA transcripts and have constructed an lncRNA-mRNA trans-regulated interaction network linked to ovarian follicle development. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation analyses have revealed that DE mRNAs and the target genes of DE lncRNAs are associated with pathways including neuroactive ligand-receptor interaction, CCR6 chemokine receptor binding, G-protein coupled receptor binding, cytokine-cytokine receptor interaction, and ECM-receptor interaction.

Conclusion

Our research presents a comprehensive compilation of lncRNAs and mRNAs linked to ovarian development. Additionally, it establishes a predictive interaction network involving differentially abundant lncRNAs and differentially expressed genes (DEGs) within TBsf. This significantly contributes to our understanding of the intricate interactions between lncRNAs and genes governing brooding behavior.

Published: April 2024

Background

Falling is a major concern for the health of older adults and significantly affects their quality of life. Identifying the various risk factors and the differences between older patients can be challenging. The objective of this study was to identify the risk factors for falls among polymedicated community-dwelling older Lebanese patients following a medication review.

Methods

In this analytical cross-sectional study, we examined the risk factors for falls in 850 patients aged ≥ 65 years who were taking ≥ 5 medications daily. The study involved conducting a medication review over the course of a year in primary care settings and using multivariate logistic regression analysis to analyze the data.

Results

Our results showed that 106 (19.5%) of the 850 included patients had fallen at least once in the three months prior to the medication review. Loss of appetite and functional dependence were identified as the most significant predictors of falls ORa = 3.020, CI [2.074–4.397] and ORa = 2.877, CI [1.787–4.632], respectively. Other risk factors for falls included drowsiness ORa = 2.172, CI [1.499–3.145], and the use of beta-blockers ORa = 1.943, CI [1.339–2.820].

Conclusion

Our study highlights the importance of addressing multiple risk factors for falls among Lebanese older adults and emphasizes the need for customized interventions and ongoing monitoring to prevent falls and improve health outcomes. This study sheds light on a critical issue in the Lebanese older population and provides valuable insight into the complex nature of falls among poly-medicated Lebanese community-dwelling older adults.

Published: April 2024

Background

Transforming growth factor-β (TGF-β) is a cytokine with multiple functions, including cell growth regulation, extracellular matrix production, angiogenesis homeostasis adjustment and et al. TGF-β pathway activation promotes tumor metastasis/progression and mediates epithelial-mesenchymal transmission suppressing immunosurveillance in advanced tumors. GFH018, a small molecule inhibitor blocking TGF-β signal transduction, inhibits the progression and/or metastasis of advanced cancers. This first-in-human study evaluated the safety, tolerability, pharmacokinetics (PK), and efficacy of GFH018 monotherapy in patients with advanced solid tumors.

Methods

This phase I, open-label, multicenter study used a modified 3+3 dose escalation and expansion design. Adult patients with advanced solid tumors failing the standard of care were enrolled. Starting at 5 mg, eight dose levels up to 85 mg were evaluated. Patients received GFH018 BID (14d-on/14d-off) starting on the 4th day after a single dose on cycle 1, day 1. Subsequent cycles were defined as 28 days. The study also explored the safety of 85 mg BID 7d-on/7d-off. Adverse events were graded using NCI criteria for adverse events (NCI-CTCAE v5.0). PK was analyzed using a noncompartmental method. Efficacy was evaluated using RECIST 1.1. Blood samples were collected for biomarker analysis.

Results

Fifty patients were enrolled and received at least one dose of GFH018. No dose-limiting toxicity occurred, and the maximum tolerated dose was not reached. Forty-three patients (86.0%) had at least one treatment-related adverse event (TRAE), and three patients (6.0%) had ≥ G3 TRAEs. The most common TRAEs (any grade/grade ≥3) were AST increased (18%/0%), proteinuria (14%/2%), anemia (14%/2%), and ALT increased (12%/0%). No significant cardiotoxicity or bleeding was observed. GFH018 PK was linear and dose-independent, with a mean half-life of 2.25–8.60 h from 5 – 85 mg. Nine patients (18.0%) achieved stable disease, and one patient with thymic carcinoma achieved tumor shrinkage, with the maximum target lesion decreased by 18.4%. Serum TGF-β1 levels were not associated with clinical responses. The comprehensive recommended dose for Phase II was defined as 85 mg BID 14d-on/14d-off.

Conclusions

GFH018 monotherapy presented a favorable safety profile without cardiac toxicity or bleeding. Modest efficacy warrants further studies, including combination strategies.

Authors: Li Anzhen , Yang Xiaowei , Wang Wei , Huang Wenbin , Ding Hui , Nie Ke , Zhong Tan , Hu Shisi , Yang Zhenduo , Zhong Xingwu
Published: April 2024

Background

This study aimed to compare the visual outcomes of the first operated eyes with those of the second operated eyes following small-incision lenticule extraction (SMILE).

Methods

A total of 202 patients (404 eyes) underwent SMILE using the tear film mark centration method for myopia and myopic astigmatism correction. Baseline characteristics, objective optical quality, decentered displacement, induced corneal aberrations, and modulation transfer function (MTF) values were assessed. Linear regression analyzed the relationship between decentration and visual quality parameters, including corneal aberrations and MTF values.

Results

No significant difference was observed in objective visual quality, efficacy, and safety indexes between the two groups (all P > 0.05). The average decentered displacement for the first and second surgical eyes was 0.278 ± 0.17 mm and 0.315 ± 0.15 mm, respectively (P = 0.002). The horizontal coma in the first surgical eyes were notably lower than in the second (P = 0.000). MTF values at spatial frequencies of 5, 10, 15, and 20 cycles/degree (c/d) were higher in the first surgical eyes compared to the second (all P < 0.05). Linear regression indicated that high-order aberrations (HOAs), root mean square (RMS) coma, spherical aberration, horizontal coma, vertical coma, and eccentric displacement were all linearly correlated. Furthermore, MTF values exhibited a linear relationship with eccentric displacement across these spatial frequencies.

Conclusions

There was no discernible difference in visual acuity, efficacy, or safety between the two operated eyes. Nonetheless, the first operated eyes exhibited reduced decentered displacement and demonstrated superior outcomes in terms of horizontal coma and MTF values compared to the second operated eyes following SMILE. The variations in visual quality parameters were linearly correlated with decentered displacement.

Published: April 2024

Background

Evidence has shown that the risk of transmission of SARS-CoV-2 is much higher in prisons than in the community. The release of the COVID-19 vaccine and the recommendation by WHO to include prisons among priority settings have led to the inclusion of prisons in national COVID-19 vaccination strategies. Evidence on prison health and healthcare services provision is limited and often focuses on a single country or institution due to the multiple challenges of conducting research in prison settings. The present study was done in the framework of the EU-founded project RISE-Vac. It aimed to analyse the best practices and challenges applied in implementing COVID-19 universal vaccination services during the pandemic to support future expansion of routine life course vaccination services for people living in prison (PLP).

Methods

Two online cross-sectional surveys were designed and piloted: survey1 on prison characteristics and (non-COVID-19) immunisation practices; survey2 on the implementation and coverage of COVID-19 vaccination with open-ended questions for thematic analysis. Each RISE-Vac project partner distributed the questionnaire to one or two prisons in their country. Answers were collected from eight European prisons’ directors or medical directors between November 2021-May 2022.

Results

According to our findings, the implementation modalities of COVID-19 vaccination services in the surveyed prisons were effective in improving PLP vaccination coverage. Strategies for optimal management of the vaccination campaign included: periodic time slot for PLP vaccination; new staff recruitment and task shifting; distribution of informational material both to PLP and prison staff. Key challenges included continuity of care after release, immunisation information system, and vaccine hesitancy.

Conclusions

To the best of our knowledge, this is the first study describing the implementation of COVID-19 vaccination services in European prisons, suggesting that the expansion of vaccination provision in prison is possible. There is no unique solution that will fit every country but commonalities likely to be important in the design and implementation of future vaccination campaigns targeting PLP emerged. Increased availability of vaccination services in prison is not only possible, but feasible and highly desirable, and can contribute to the reduction of health inequalities.
Evidence-based interventions for identifying candidate quality indicators to assess quality of care in diabetic foot clinics: a scoping review
Authors: Lusendi Flora Mbela , Vanherwegen An-Sofie , Doggen Kris , Nobels Frank , Matricali Giovanni Arnoldo
Published: April 2024

Background

Foot ulcers in people with diabetes are a serious complication requiring a complex management and have a high societal impact. Quality monitoring systems to optimize diabetic foot care exist, but a formal and more evidence-based approach to develop quality indicators (QIs) is lacking. We aimed to identify a set of candidate indicators for diabetic foot care by adopting an evidence-based methodology.

Methods

A systematic search was conducted across four academic databases: PubMed, Embase CINAHL and Cochrane Library. Studies that reported evidence-based interventions related to organization or delivery of diabetic foot care were searched. Data from the eligible studies were summarized and used to formulate process and structure indicators. The evidence for each candidate QI was described in a methodical and transparent manner. The review process was reported according to the “Preferred Reported Items for Systematic reviews and Meta-Analysis” (PRISMA) statements and its extension for scoping reviews.

Results

In total, 981 full-text articles were screened, and 322 clinical studies were used to formulate 42 candidate QIs.

Conclusions

An evidence-based approach could be used to select candidate indicators for diabetic foot ulcer care, relating to the following domains: wound healing interventions, peripheral artery disease, offloading, secondary prevention, and interventions related to organization of care. In a further step, the feasibility of the identified set of indicators will be assessed by a multidisciplinary panel of diabetic foot care stakeholders.
Modified technique of Hepatojejunostomy for biliary tract reconstruction after resection of tumors affecting the perihilar region: a case series
Authors: Kuang Yi , Ji Ran , Yuan Tao , Liu Menggang
Published: April 2024

Backgrounds

Radical resection is the most effective treatment for perihilar tumors. Biliary tract reconstruction after resection is one of the key steps in this surgery. Mucosa-to-mucosa cholangiojejunostomy is traditionally performed, in which the bile ducts at the resection margin are separately anastomosed to the jejunum. However, this approach is associated with long operative time and high risk of postoperative complications. The present study presents a modified technique of hepatojejunostomy and its outcomes.

Methods

The data of patients who underwent hepatojejunostomy using the modified technique at the Department of Hepatobiliary Surgery, Daping Hospital, Army Medical University, Chongqing, China, from January 2016 to December 2021, were retrospectively analyzed.

Results

A total of 13 patients with perihilar tumors underwent R0 resection and bilioenteric reconstruction using the modified hepatojejunostomy technique during the study period. During the operation, the alignment of the bile duct stumps was improved, the posterior wall of the anastomosis was reinforced, internal stents were placed in the smaller bile ducts, external stents were placed in the larger bile ducts, and hepatojejunostomy was performed using 4 − 0 prolene. No serious postoperative complications, such as death or bile leakage, occurred during the hospitalization. Furthermore, there were no cases of biliary stricture or cholangitis after the six-month follow-up period.

Conclusion

The modified hepatojejunostomy technique is a safe and effective technique of biliary reconstruction after the resection of perihilar tumors. This can be easily performed for difficult cases with multiple bile ducts that require reconstruction after resection.
Two-year clinical and radiographic evaluation of ACTIVA BioACTIVE versus Compomer (Dyract® eXtra) in the restoration of class-2 cavities of primary molars: a non-inferior split-mouth randomised clinical trial
Authors: Banon Reda , Vandenbulcke Jeroen , Van Acker Jakob , Martens Luc , De Coster Peter , Rajasekharan Sivaprakash
Published: April 2024

Objectives

The trial aimed to compare the clinical performance and radiographic success of ACTIVA BioACTIVE versus Compomer in restoring class-II cavities of primary molars.

Materials and methods

A non-inferior split-mouth design was considered. A pre-calculated sample size of 96 molars (48 per group) with class-2 cavities of twenty-one children whose ages ranged from 5 to 10 years were randomly included in the trial. Pre-operative Plaque Index (PI), DMFT/dmft scores and the time required to fill the cavity were recorded. Over 24 months, the teeth were clinically evaluated every six months and radiographically every 12 months by two calibrated and blinded evaluators using the United States public health service (USPHS)-Ryge criteria. The two-sided 95% confidence interval (CI) for the difference in success rate was considered to assess non-inferiority, and the margin was set at -18%. The linear mixed model and Firth’s logistic regression model were used for data analysis (P < 0.05).

Results

After 24 months, 86 teeth (43 per group) were evaluated. The mean PI score was 1.1(± 0.9), while DMFT/dmft was 0.35 (± 0.74) and 6.55 (± 2.25) respectively. The clinical and radiographic success rate of Dyract vs. ACTIVA was 95.3% and 88.3% vs. 93% and 86%, respectively. The two-sided 95% CI for the difference in success rate (-2.3%) was − 3.2 to 1.3% and didn’t reach the predetermined margin of -18% which had been anticipated as the non-inferiority margin. Clinically, ACTIVA had a significantly better colour match (P = 0.002) but worse marginal discolouration (P = 0.0143). There were no significant differences regarding other clinical or radiographic criteria (P > 0.05). ACTIVA took significantly less placement time than Dyract, with a mean difference of 2.37 (± 0.63) minutes (P < 0.001).

Conclusion

The performance of ACTIVA was not inferior to Dyract and both materials had a comparable high clinical and radiographic performance in children with high-caries experience. ACTIVA had a significantly better colour match but more marginal discolouration. It took significantly less time to be placed in the oral cavity.

Determinants of respectful maternity care among women who gave childbirth in Southern Ethiopia
Authors: Utalo Dawit , Israel Eskinder , Lenjebo Tsegaye Lolaso , Aynalem Amdehiwot , Darebo Tadele Dana
Published: April 2024

Background

Having a good provision of respectful maternity care (RMC) to a woman who gives childbirth is a crucial component of maternal health care to result in positive maternal and neonatal outcomes. Disrespect and lack of women-centered care in birth discourage a woman from seeking healthcare during childbirth contributing to poor healthcare-seeking behaviour and dissatisfaction with the maternity service. The current study aimed to assess key determinants of RMC during childbirth at selected public health facilities of the Gofa zone, Southern Ethiopia.

Methods

A cross-sectional study design was conducted from March to April 2021 among 390 women who gave birth in eight randomly selected public health facilities of Gofa zone, Southern Ethiopia. The level of RMC was measured using structured exit interview items. A structured-interviewer-administered questionnaire was used to collect data and then entered into Epi-data version 4.6 and exported to SPSS version 25 for further analysis. Bivariate and multivariate logistic regression analyses were used to identify determinants of RMC among women.

Results

A total of 390 women responded to the exit interview making a response rate of 100%. The mean (± SD) age of the 390 women was 27.9 (± 4.85) years. The overall prevalence of women who received RMC was 40.5%, 95% CI (36-45%). Two hundred and ninety-seven (76.2%; n = 297/390) women had antenatal care (ANC) attendance in the index pregnancy. A woman who had planned pregnancy (AOR = 1.72, CI: 1.04, 2.85), planned to deliver in a health facility (AOR = 1.68, CI: 1.00, 2.81), presence of familial support (AOR = 2.04, CI: 1.20, 3.48), and had information about service availability (AOR = 4.44, CI: 2.09, 9.42) were associated with RMC among women.

Conclusion

The provision of respectful maternity care in the study area was low when compared with local studies. Planned pregnancy, plan to deliver in a health facility, family support, and presence of information about service availability were factors associated with RMC among women. More attention should be given to training and supportive supervision of health care professionals on respectful maternity care and its standards to increase service uptake and make service more women-centred.

Published: April 2024

Introduction

Understanding of the needs of people with stroke at hospital discharge and in the first six-months is limited. This study aim was to profile and document the needs of people with stroke at hospital discharge to home and thereafter.

Methods

A prospective cohort study recruiting individuals with stroke, from three hospitals, who transitioned home, either directly, through rehabilitation, or with early supported discharge teams. Their outcomes (global-health, cognition, function, quality of life, needs) were described using validated questionnaires and a needs survey, at 7–10 days, and at 3-, and 6-months, post-discharge.

Results

72 patients were available at hospital discharge; mean age 70 (SD 13); 61% female; median NIHSS score of 4 (IQR 0–20). 62 (86%), 54 (75%), and 45 (63%) individuals were available respectively at each data collection time-point. Perceived disability was considerable at hospital discharge (51% with mRS ≥ 3), and while it improved at 3-months, it increased thereafter (35% with mRS ≥ 3 at 6-months). Mean physical health and social functioning were “fair” at hospital discharge and ongoing; while HR-QOL, although improved over time, remained impaired at 6-months (0.69+/-0.28). At 6-months cognitive impairment was present in 40%. Unmet needs included involvement in transition planning and care decisions, with ongoing rehabilitation, information, and support needs. The median number of unmet needs at discharge to home was four (range:1–9), and three (range:1–7) at 6-months.

Conclusion

Stroke community reintegration is challenging for people with stroke and their families, with high levels of unmet need. Profiling outcomes and unmet needs for people with stroke at hospital-to-home transition and onwards are crucial for shaping the development of effective support interventions to be delivered at this juncture.

Fossil-calibrated molecular clock data enable reconstruction of steps leading to differentiated multicellularity and anisogamy in the Volvocine algae
Authors: Lindsey Charles Ross , Knoll Andrew H. , Herron Matthew D. , Rosenzweig Frank
Published: April 2024

Background

Throughout its nearly four-billion-year history, life has undergone evolutionary transitions in which simpler subunits have become integrated to form a more complex whole. Many of these transitions opened the door to innovations that resulted in increased biodiversity and/or organismal efficiency. The evolution of multicellularity from unicellular forms represents one such transition, one that paved the way for cellular differentiation, including differentiation of male and female gametes. A useful model for studying the evolution of multicellularity and cellular differentiation is the volvocine algae, a clade of freshwater green algae whose members range from unicellular to colonial, from undifferentiated to completely differentiated, and whose gamete types can be isogamous, anisogamous, or oogamous. To better understand how multicellularity, differentiation, and gametes evolved in this group, we used comparative genomics and fossil data to establish a geologically calibrated roadmap of when these innovations occurred.

Results

Our ancestral-state reconstructions, show that multicellularity arose independently twice in the volvocine algae. Our chronograms indicate multicellularity evolved during the Carboniferous-Triassic periods in Goniaceae + Volvocaceae, and possibly as early as the Cretaceous in Tetrabaenaceae. Using divergence time estimates we inferred when, and in what order, specific developmental changes occurred that led to differentiated multicellularity and oogamy. We find that in the volvocine algae the temporal sequence of developmental changes leading to differentiated multicellularity is much as proposed by David Kirk, and that multicellularity is correlated with the acquisition of anisogamy and oogamy. Lastly, morphological, molecular, and divergence time data suggest the possibility of cryptic species in Tetrabaenaceae.

Conclusions

Large molecular datasets and robust phylogenetic methods are bringing the evolutionary history of the volvocine algae more sharply into focus. Mounting evidence suggests that extant species in this group are the result of two independent origins of multicellularity and multiple independent origins of cell differentiation. Also, the origin of the Tetrabaenaceae-Goniaceae-Volvocaceae clade may be much older than previously thought. Finally, the possibility of cryptic species in the Tetrabaenaceae provides an exciting opportunity to study the recent divergence of lineages adapted to live in very different thermal environments.
Association of circulating biomarkers with illness severity measures differentiates myalgic encephalomyelitis/chronic fatigue syndrome and post-COVID-19 condition: a prospective pilot cohort study
Authors: Domingo Joan Carles , Battistini Federica , Cordobilla Begoña , Zaragozá Maria Cleofé , Sanmartin-Sentañes Ramón , Alegre-Martin Jose , Cambras Trinitat , Castro-Marrero Jesus
Published: April 2024

Background

Accumulating evidence suggests that autonomic dysfunction and persistent systemic inflammation are common clinical features in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID. However, there is limited knowledge regarding their potential association with circulating biomarkers and illness severity in these conditions.

Methods

This single-site, prospective, cross-sectional, pilot cohort study aimed to distinguish between the two patient populations by using self-reported outcome measures and circulating biomarkers of endothelial function and systemic inflammation status. Thirty-one individuals with ME/CFS, 23 individuals with long COVID, and 31 matched sedentary healthy controls were included. All study participants underwent non-invasive cardiovascular hemodynamic challenge testing (10 min NASA lean test) for assessment of orthostatic intolerance. Regression analysis was used to examine associations between outcome measures and circulating biomarkers in the study participants. Classification across groups was based on principal component and discriminant analyses.

Results

Four ME/CFS patients (13%), 1 with long COVID (4%), and 1 healthy control (3%) presented postural orthostatic tachycardia syndrome (POTS) using the 10-min NASA lean test. Compared with matched healthy controls, ME/CFS and long COVID subjects showed higher levels of ET-1 (p < 0.05) and VCAM-1 (p < 0.001), and lower levels of nitrites (NOx assessed as NO2- + NO3-) (p < 0.01). ME/CFS patients also showed higher levels of serpin E1 (PAI-1) and E-selectin than did both long COVID and matched control subjects (p < 0.01 in all cases). Long COVID patients had lower TSP-1 levels than did ME/CFS patients and matched sedentary healthy controls (p < 0.001). As for inflammation biomarkers, both long COVID and ME/CFS subjects had higher levels of TNF-α than did matched healthy controls (p < 0.01 in both comparisons). Compared with controls, ME/CFS patients had higher levels of IL-1β (p < 0.001), IL-4 (p < 0.001), IL-6 (p < 0.01), IL-10 (p < 0.001), IP-10 (p < 0.05), and leptin (p < 0.001). Principal component analysis supported differentiation between groups based on self-reported outcome measures and biomarkers of endothelial function and inflammatory status in the study population.

Conclusions

Our findings revealed that combining biomarkers of endothelial dysfunction and inflammation with outcome measures differentiate ME/CFS and Long COVID using robust discriminant analysis of principal components. Further research is needed to provide a more comprehensive characterization of these underlying pathomechanisms, which could be promising targets for therapeutic and preventive strategies in these conditions.
Isolation and genetic characteristics of Novel H4N1 Avian Influenza viruses in ChongQing, China
Authors: He Jinyue , Deng Jing , Wen Xianxian , Yan Mengyuan , Liu Yang , Zhou Yunqiu , Du XuBin , Yang Han , Peng Xiaobin
Published: April 2024

Background

Avian influenza viruses (AIVs) constitute significant zoonotic pathogens encompassing a broad spectrum of subtypes. Notably, the H4 subtype of AIVs has a pronounced ability to shift hosts. The escalating prevalence of the H4 subtype heightens the concern for its zoonotic potential, signaling an urgent need for vigilance.

Methods

During the period from December 2021 to November 2023, we collected AIV-related environmental samples and assessed them using a comprehensive protocol that included nucleic acid testing, gene sequencing, isolation culture, and resequencing.

Results

In this study, a total of 934 environmental samples were assessed, revealing a remarkably high detection rate (43.66%, 289/662) of AIV in the live poultry market. Notably, the H4N1 subtype AIV (cs2301) was isolated from the live poultry market and its complete genome sequence was successfully determined. Subsequent analysis revealed that cs2301, resulting from a reassortment event between wild and domesticated waterfowl, exhibits multiple mutations and demonstrates potential for host transfer.

Conclusions

Our research once again demonstrates the significant role of wild and domesticated waterfowl in the reassortment process of avian influenza virus, enriching the research on the H4 subtype of AIV, and emphasizing the importance of proactive monitoring the environment related to avian influenza virus.
Pfp-fm: an accelerated FM-index
Authors: Hong Aaron , Oliva Marco , Köppl Dominik , Bannai Hideo , Boucher Christina , Gagie Travis
Published: April 2024

FM-indexes are crucial data structures in DNA alignment, but searching with them usually takes at least one random access per character in the query pattern. Ferragina and Fischer [1] observed in 2007 that word-based indexes often use fewer random accesses than character-based indexes, and thus support faster searches. Since DNA lacks natural word-boundaries, however, it is necessary to parse it somehow before applying word-based FM-indexing. In 2022, Deng et al. [2] proposed parsing genomic data by induced suffix sorting, and showed that the resulting word-based FM-indexes support faster counting queries than standard FM-indexes when patterns are a few thousand characters or longer. In this paper we show that using prefix-free parsing—which takes parameters that let us tune the average length of the phrases—instead of induced suffix sorting, gives a significant speedup for patterns of only a few hundred characters. We implement our method and demonstrate it is between 3 and 18 times faster than competing methods on queries to GRCh38, and is consistently faster on queries made to 25,000, 50,000 and 100,000 SARS-CoV-2 genomes. Hence, it seems our method accelerates the performance of count over all state-of-the-art methods with a moderate increase in the memory. The source code for $$\texttt {PFP-FM}$$

Anopheles sacharovi in Italy: first record of the historical malaria vector after over 50 years
Authors: Raele Donato Antonio , Severini Francesco , Toma Luciano , Menegon Michela , Boccolini Daniela , Tortorella Giovanni , Di Luca Marco , Cafiero Maria Assunta
Published: April 2024

Background

Anopheles sacharovi, a member of the Anopheles maculipennis complex, was a historical malaria vector in Italy, no longer found since the last report at the end of 1960s. In September 2022, within the Surveillance Project for the residual anophelism, a single specimen of An. maculipennis sensu lato collected in Lecce municipality (Apulia region) was molecularly identified as An. sacharovi. This record led to implement a targeted entomological survey in September 2023.

Methods

Investigation was conducted in the areas around the first discovery, focusing on animal farms, riding stables and potential breeding sites. Adult and immature mosquitoes were collected, using active search or traps, in several natural and rural sites. Mosquitoes belonging to An. maculipennis complex were identified morphologically and molecularly by a home-made routine quantitative polymerase chain reaction (qPCR) assay, developed specifically for the rapid identification of An. labranchiae, and, when necessary, by amplification and sequencing of the ITS-2 molecular marker.

Results

Out of the 11 sites investigated, 6 were positive for Anopheles presence. All 20 An. maculipennis s.l. (7 adults, 10 larvae and 3 pupae) collected in the areas were identified as An. sacharovi by ITS-2 sequencing.

Conclusions

The discovery of An. sacharovi, considered to have disappeared from Italy for over 50 years, has a strong health relevance and impact, highlighting an increase in the receptivity of the southern areas. As imported malaria cases in European countries are reported every year, the risk of Plasmodium introduction by gametocyte carriers among travellers from endemic countries should be taken into greater consideration. Our findings allow rethinking and building new models for the prediction and expansion of introduced malaria. Furthermore, to prevent the risk of reintroduction of the disease, the need to strengthen the surveillance of residual anophelism throughout the South should be considered.

Heat stress is one of the major abiotic stresses affecting the growth, sporulation, colonization and survival of Trichoderma viride. This study aimed to gain a better insight into the underlying mechanism governing the heat stress response of T. viride Tv-1511. We analysed the transcriptomic changes of Tv-1511 under normal and heat stress conditions using RNA sequencing. We observed that Tv-1511 regulates the biosynthesis of secondary metabolites through a complex network of signalling pathways. Additionally, it significantly activates the anti-oxidant defence system, heat shock proteins and stress-response-related transcription factors in response to heat stress. TvHSP70 was identified as a key gene, and transgenic Tv-1511 overexpressing TvHSP70 (TvHSP70-OE) was generated. We conducted an integrated morphological, physiological and molecular analyses of the TvHSP70-OE and wild-type strains. We observed that TvHSP70 over-expression significantly triggered the growth, anti-oxidant capacity, anti-fungal activity and growth-promoting ability of Tv-1511. Regarding anti-oxidant capacity, TvHSP70 primarily up-regulated genes involved in enzymatic and non-enzymatic anti-oxidant systems. In terms of anti-fungal activity, TvHSP70 primarily activated genes involved in the synthesis of enediyne, anti-fungal and aminoglycoside antibiotics. This study provides a comparative analysis of the functional significance and molecular mechanisms of HSP70 in Trichoderma. These findings provide a valuable foundation for further analyses.

Introduction

Antimicrobial resistance (AMR) is a pressing global health concern, particularly pronounced in low-resource settings. In Ethiopia, the escalating prevalence of carbapenem-resistant Pseudomonas aeruginosa (P. aeruginosa) poses a substantial threat to public health.

Methods

A comprehensive search of databases, including PubMed, Scopus, Embase, Hinari, and Google Scholar, identified relevant studies. Inclusion criteria encompassed observational studies reporting the prevalence of meropenem-resistant P. aeruginosa in Ethiopia. Quality assessment utilized JBI checklists. A random-effects meta-analysis pooled data on study characteristics and prevalence estimates, with subsequent subgroup and sensitivity analyses. Publication bias was assessed graphically and statistically.

Results

Out of 433 studies, nineteen, comprising a total sample of 11,131, met inclusion criteria. The pooled prevalence of meropenem-resistant P. aeruginosa was 15% (95% CI: 10–21%). Significant heterogeneity (I2 = 83.6%) was observed, with the number of P. aeruginosa isolates identified as the primary source of heterogeneity (p = 0.127). Subgroup analysis by infection source revealed a higher prevalence in hospital-acquired infections (28%, 95% CI: 10, 46) compared to community settings (6%, 95% CI: 2, 11). Geographic based subgroup analysis indicated the highest prevalence in the Amhara region (23%, 95% CI: 8, 38), followed by Addis Ababa (21%, 95% CI: 11, 32), and lower prevalence in the Oromia region (7%, 95% CI: 4, 19). Wound samples exhibited the highest resistance (25%, 95% CI: 25, 78), while sputum samples showed the lowest prevalence. Publication bias, identified through funnel plot examination and Egger’s regression test (p < 0.001), execution of trim and fill analysis resulted in an adjusted pooled prevalence of (3.7%, 95% CI: 2.3, 9.6).

Conclusion

The noteworthy prevalence of meropenem resistance among P. aeruginosa isolates in Ethiopia, particularly in healthcare settings, underscores the urgency of implementing strict infection control practices and antibiotic stewardship. Further research is imperative to address and mitigate the challenges posed by antimicrobial resistance in the country.
Drivers of perceived discrimination among older adults in India: an intersectional analysis
Authors: Chakraborty Jayantika , Kundu Sampurna
Published: April 2024

Discrimination is harmful action taken against individuals or groups to protect customary relations of power and privilege. Older adults are particularly vulnerable to experiences of discrimination that adversely affect their quality of life. We use data from the Longitudinal Ageing Study of India (LASI; Wave 1; 2017–2018) to examine different contextual forces that shape the experiences of discrimination in older adults in India, specifically gender, caste, and economic condition. We used the theory of intersectionality to hypothesize that economic condition, caste, and gender combine uniquely to engender perceived discrimination in older adults. We first used a concentration index to determine the sample’s pre-existing inequality levels. The concentration curve evidenced a disproportionate concentration of discrimination among people with low income. Next, we used a three-way ANCOVA to examine the effects of caste, gender, and economic condition on individuals’ experiences of discrimination. A significant interaction effect of caste, gender, and economic condition [F(1, 30,394) = 8.91 p = 0.003] evidenced the compounding effects of inequalities on experiences of discrimination. Finally, we ran a moderation model to test the ameliorating effects of education on experiences of discrimination experienced by marginalized castes. The model was significant (β= -0.192; p < 0.001), thereby supporting the proposition that increased education level can lead to an increased sense of belonging and perceptions of equal treatment, which relate negatively to perceived discrimination. Results are discussed considering intersectionality in peoples’ struggles and resilience in India.

Scientifically validating the value of rural heritage and exploring construction wisdom has emerged as a significant challenge in the study of rural settlements worldwide. Rural heritage shows significant differences according to the natural environment, history, culture, and socio-economic factors. However, the assessment of the authenticity and effectiveness of heritage values have yet to be quantified due to the difficulty in obtaining evidence directly from samples. By constructing a multi-dimensional model of villages for quantitative analysis, we proposed a multifaceted spatial visibility analysis method based on individual and combined defense structures to empirically study the remains of eight towers in Moluo village, western China. This study demonstrated that towers serve as regional defense structures and are essential for constructing a comprehensive and effective visual defensive system (VDS) in Moluo village, a typical military defense village. The effectiveness and coverage of the towers vary depending on their location, height, type, and other factors. They form a complementary and synergistic relationship, playing a dual mechanism of public and private, local and overall defense. In summary, this method enables the feasible quantification and analysis of the functional value of rural heritage through landscape visual analysis. It provides a new perspective for studying the authenticity of heritage functions.

Background

GAox is a key enzyme involved in GA biosynthesis pathway and plays an important role in regulating various processes in plant life cycle. However, it has not been systematic, studies have been conducted in potato, which is the world's fourth largest food crop.

Methods

In this work, we systematically identified GAox gene family (StGAox) in potato by analyzing the potato genome sequence using a set of bioinformatics approaches, and analyze their physical, chemical properties, distribution on chromosomes, gene structure, conserved motifs, gene duplication events and expression patterns were analyzed.

Results

The results showed that a total of 33 GAox proteins were identified and unevenly distributed on 10 chromosomes. Based on their protein structure and phylogenetic characteristics, these 33 StGAoxes were divided into 5 distinct subclasses. Collinearity analysis revealed that there were 5 pairs of duplicated genes in the StGAox gene family, and all of which evolved under purifying selection. Analysis of RNA-seq data of double haploid (DM) potatoes under different tissues, abiotic stresses and hormone treatments showed that PG0002068, PG0024249 and PG0027963 were higher expressed in leaves, PG009427, PG0026762, PG0009021 and PG0021095 were higher expressed in tubers, PG2003479, PG0024249, PG0005698, and PG0009021were higher expressed in shoots than those of other tissues. In addition, the expression of PG0002068, PG2003479, PG0032156, PG0024249, and PG0021292 were up-regulated under mannitol and drought stress.

Conclusions

Comparative genome-wide analysis of StGAox genes and their expression analyses revealed that members of this family may be involved in tissue-specific developmental and abiotic stress responses.

Background

Brassicas (Brassicaceae) are recognized as excellent sources of nutrients and bioactive compounds. Among these, wild turnip (Brassica rapa L.), holds significant promising nutritional properties owed to its abundant glucosinolates and phenolic compounds. To enhance its potential values, the application of elicitors is crucial and good strategy prompting an enrichment in the concentration of phytochemicals, as well established in other relevant Brassicas, such as broccoli. While the responses triggered by certain elicitors such as salicylic acid, methyl jasmonate, or chitosan are widely documented, little is known about the impact of electrolyzed water, an economically viable elicitor. Through elicitation strategies, the aim of this work was to unravel insights into enhancing the phytochemical content of wild turnip sprouts for potential use as healthy food, comparing with well-studied broccoli as control of the experiments.

Results

Our findings revealed that wild turnip exhibited a notable higher glucosinolate (GSL) contents (487–712 mg 100 g−1 D.W.), than in broccoli sprouts. Furthermore, the use of electrolyzed water (2 vol.) boosted the accumulation of glucosinolates with significant increase up to twofolds the content. Specifically, treatments with salicylic acid (250 μM) and electrolyzed water (2 vol.) favored the significant increase of mainly aliphatic GSL (progoitrin, PRO; gluconapin, GNA; glucobrassicin, GBN). On the other hand, natural antioxidants such as of the characteristic acylated cyanidins present in wild turnip sprouts were not affected by the elicitor treatments, indicative of higher tolerance to oxidative stress in wild turnip.

Conclusions

These observations underlined the potential of using electrolyzed water in wild turnips as elicitor for GSL-enriched food ingredients. Further studies will be necessary to align with the broader goal of evaluating abiotic and biotic factors affecting the phytochemical composition in mature organs not only in germinating seeds and sprouts, for agricultural performance for quality and healthy foods purposes.
