Evaluation of different bermudagrass germplasm at physiological and molecular level under shade along longitudinal and latitudinal gradients.

Responses of turfgrass to shade vary in individual species, and the degree and quality of low light; therefore, the selection of low light tolerant cultivars of turfgrass is important and beneficial for turf management rather than other practices. The stolons of thirteen bermudagrass genotypes were planted with two treatments and three replications of each treatment to establish for one month in the Yangzhou University Jiangsu China greenhouse. The established plants were transferred outside of the greenhouse, and 50% shading was applied to them with a black net. After 30 days of stress treatment, the morpho-physiological and biochemical analyses were performed. The expression of genes such as HEMA, HY5, PIF4, and Cu/ZnSOD was assessed. Cynodon dactylon is a C4, and perennial that grows as lawn grass and is used as forage. Based on different indicator measurements, the most shade-tolerant germplasm was L01 and L06 along the longitudes and L09 and L10 along the latitudes. At the same time, L02 and L08 were more susceptible, respectively. However, germplasm showed greater tolerance in higher latitudes while longitudinal plants showed less stress response. The current study aimed (1) to screen out the most shade-tolerant Cynodon dactylon genotype among 13 along longitudinal and latitudinal gradients in China. (2) to examine morpho-physiological indicators of different bermudagrassgenotypes; (3) to evaluate if and how differences in various indicators of bermudagrass correlated with geographic region. This study will significantly advance the use of Cynodon germplasm in breeding, genomics, management, nomenclature, and phylogeographical study. It will decisively define whether natural selection and migration can drive evolutionary responses for populations to adapt to their new environments effectively.

Assessment of the changes in growth, photosynthetic traits and gene expression in Cynodon dactylon against drought stress.

Drought stress considered a key restrictive factor for a warm-season bermudagrass growth during summers in China. Genotypic variation against drought stress exists among bermudagrass (Cynodon sp.), but the selection of highly drought-tolerant germplasm is important for its growth in limited water regions and for future breeding. Our study aimed to investigate the most tolerant bermudagrass germplasm among thirteen, along latitude and longitudinal gradient under a well-watered and drought stress condition. Current study included high drought-resistant germplasm, "Tianshui" and "Linxiang", and drought-sensitive cultivars; "Zhengzhou" and "Cixian" under drought treatments along longitude and latitudinal gradients, respectively. Under water deficit conditions, the tolerant genotypes showed over-expression of a dehydrin gene cdDHN4, antioxidant genes Cu/ZnSOD and APX which leads to higher antioxidant activities to scavenge the excessive reactive oxygen species and minimizing the membrane damage. It helps in maintenance of cell membrane permeability and osmotic adjustment by producing organic osmolytes. Proline an osmolyte has the ability to keep osmotic water potential and water use efficiency high via stomatal conductance and maintain transpiration rate. It leads to optimum CO2 assimilation rate, high chlorophyll contents for photosynthesis and elongation of leaf mesophyll, palisade and thick spongy cells. Consequently, it results in elongation of leaf length, stolon and internode length; plant height and deep rooting system. The CdDHN4 gene highly expressed in "Tianshui" and "Youxian", Cu/ZnSOD gene in "Tianshui" and "Linxiang" and APX gene in "Shanxian" and "Linxiang". The genotypes "Zhongshan" and "Xiaochang" showed no gene expression under water deficit conditions. Our results indicate that turfgrass show morphological modifications firstly when subjected to drought stress; however the gene expression is directly associated and crucial for drought tolerance in bermudagrass. Hence, current research has provided excellent germplasm of drought tolerant bermudagrass for physiological and molecular study and future breeding.

Temporal analogs of electromagnetically induced transparency, induced absorption, and Fano resonance.

We describe the occurrence of electromagnetically induced transparency (EIT), electromagnetically induced absorption (EIA), and Fano resonance due to time-controlled discontinuities in the refractive index of a medium, which leads to the formation of a double-cavity system inside a temporal photonic crystal. The temporal resonances partly resemble the optical resonances arising in conventional microcavities, since the amplified temporal EIA displays distinct spectral characteristics. Although an amplified EIT does not occur, a strongly amplified EIA affects the behavior of EIT as well. Besides modifying the temporal resonances via coupled-cavity interactions, we reveal refractive index-controlled temporal resonances. This computational study paves the way to probe the temporally driven coherent phenomena of EIT and EIA with potential applications such as slow-light, amplified fast-light, amplified ultranarrow bandwidth optical filters, and multicavity systems.

Modulation of apoptosis and Inflammasome activation in chondrocytes: co-regulatory role of Chlorogenic acid.

BACKGROUND: The B-cell lymphoma 2 (Bcl-2) protein regulates programmed cell death throughout the disease conditions by upholding apoptotic pathways. However, the mechanism by which it's expressed in chondrocytes still needs to be studied in chondrocyte-related disorders. Additionally, exploring the potential therapeutic role of Chlorogenic acid (CGA) in confluence with Bcl-2 modulation is of significant interest. METHODS: In vivo and in vitro studies were performed according to our previous methodologies. The chondrocytes were cultured in specific growth media under standard conditions after expression verification of different microRNAs through high-throughput sequencing and verification of Bcl-2 involvement in tibial growth plates. The effect of Bcl-2 expression was investigated by transfecting chondrocytes with miR-460a, siRNA, and their negative controls alone or in combination with CGA. The RNA was extracted and subjected to a reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Western blot analysis and immunofluorescence assays were performed to visualize the intracellular localization of Bcl-2 and associated proteins related to apoptotic and inflammasome pathways. Moreover, apoptosis through flow cytometry was also performed to understand the modulation of concerning pathways. RESULTS: The suppression of Bcl-2 induced higher apoptosis and mitochondrial dysfunction, leading to IL-1ß maturation and affecting the inflammasome during chondrocyte proliferation. Conversely, overexpression attenuated the activation, as evidenced by reduced caspase activity and IL-1ß maturation. In parallel, CGA successfully reduced siRNA-induced apoptosis by decreasing Cytochrome C (Cyto C) release from the mitochondria to the cytoplasm, which in turn decreased Caspase-3 and Caspase-7 cleavage with Bcl-2-associated X protein (Bax). Furthermore, siBcl-2 transfection and CGA therapy increased chondrocyte proliferation and survival. The CGA also showed a promising approach to maintaining chondrocyte viability by inhibiting siRNA-induced apoptosis. CONCLUSIONS: Targeting Bcl-2-mediated regulation might be a possible treatment for chondrocyte-related conditions. Moreover, these results add knowledge of the complicated processes underlying chondrocyte function and the pathophysiology of related diseases, highlighting the significance of target specific therapies.

UV-spectrophotometric Optimization of Temperature, pH, Concentration and Time for Eucalyptus Globulus Capped Silver Nanoparticles Synthesis, their Characterization and Evaluation of Biological Applications.

Morphology (size, shape) and structural variations (bonding pattern, crystallography, and atomic arrangements) have significant impacts on the efficacy of the metallic nanoparticles. Fabrication of these metal nanoparticles through green synthesis using plant extracts has increased attention due to their low cost, less hazardous byproducts, and multiple applications. In present study, Eucalyptus globulus extract was used to synthesize silver nanoparticles (AgNPs). Change of color from light brown to reddish brown and UV-visible spectral peak at 423 nm confirmed the formation of AgNPs. The shifting of FTIR spectra peaks indicated the potential role of the functional groups in extract as capping agents. The DLS evaluated the average size and stability of the nanoparticles while the surface morphology, size and the elemental composition of the AgNPs was established by the FESEM and EDX analysis. The SEM images revealed spherical nanoparticles of size ranging from 40-60 nm. Biogenic AgNPs showed better DPPH radical scavenging activity with IC50 (13.44 ± 0.3) as compared to leaves extract with IC50 (10.57 ± 0.2). The synthesized AgNPs showed higher zones of inhibition (ZOI) by well diffusion method against Escherichia coli, Staphylococcus aureus and Klebsiella pneumoniae. Results of present study highlights the potential benefits of Eucalyptus globulus leaves extract-based AgNPs for various biomedical uses.

From port to planet: Assessing NO2 pollution and climate change effects with Sentinel-5p satellite imagery in maritime zones.

The growing effects of climate change on Malaysia's coastal ecology heighten worries about air pollution, specifically caused by urbanization and industrial activity in the maritime sector. Trucks and vessels are particularly noteworthy for their substantial contribution to gas emissions, including nitrogen dioxide (NO2), which is the primary gas released in port areas. The application of advanced analysis techniques was spurred by the air pollution resulting from the combustion of fossil fuels such as fuel oil, natural gas and gasoline in vessels. The study utilized satellite photos captured by the Tropospheric Monitoring Instrument (TROPOMI) on the Sentinel-5P satellite to evaluate the levels of NO2 gas pollution in Malaysia's port areas and exclusive economic zone. Before the COVID-19 pandemic, unrestricted gas emissions led to persistently high levels of NO2 in the analyzed areas. The temporary cessation of marine industry operations caused by the pandemic, along with the halting of vessels to prevent the spread of COVID-19, resulted in a noticeable decrease in NO2 gas pollution. In light of these favourable advancements, it is imperative to emphasize the need for continuous investigation and collaborative endeavours to further alleviate air contamination in Malaysian port regions, while simultaneously acknowledging the wider consequences of climate change on the coastal ecology. The study underscores the interdependence of air pollution, maritime activities and climate change. It emphasizes the need for comprehensive strategies that tackle both immediate environmental issues and the long-term sustainability and resilience of coastal ecosystems in the context of global climate challenges.

Evaluating climate change impacts on reef environments via multibeam echosounder and Acoustic Doppler Current profiler technology.

Crucial to the Earth's oceans, ocean currents dynamically react to various factors, including rotation, wind patterns, temperature fluctuations, alterations in salinity and the gravitational pull of the moon. Climate change impacts coastal ecosystems, emphasizing the need for understanding these currents. This study explores multibeam echosounder (MBES), specifically R2-Sonic 2020 instrument, offering detailed seabed information. Investigating coral reefs, rocky reefs and artificial reefs aimed to map seafloor currents movement and their climate change responses. MBES data viz. Bathymetry and backscatter were classified and acoustic doppler current profiler (ADCP) ground data were validated using random forest regression. Results indicated high precision in currents speed measurement i.e. coral reefs with 0.96, artificial reefs with 0.94 and rocky reefs with 0.97. Currents direction accuracy was notable in coral reefs with 0.85, slightly lower in rocky reefs with 0.72 and artificial reefs with 0.60. Random forest identified sediment and backscatter as key for speed prediction while direction relies on bathymetry, slope and aspect. The study emphasizes integrating sediment size, backscatter, bathymetry and ADCP data for seafloor current analysis. This multibeam data on sediments and currents support better marine spatial planning and determine biodiversity patterns planning in the reef area.

Optimising Laparoscopic Artificial Insemination in Lohi Sheep: Effects of Timing, Sperm Concentration and Body Condition on Fertility Outcome in Subtropical Climates.

The objective of this study was to determine the optimal timing, sperm concentration, and body condition score (BCS) for laparoscopic artificial insemination (LAI) in the subtropical Lohi sheep breed. In Experiment 1, Lohi ewes (n = 80) were synchronised through progestin-sponges (day 0-day 11), administering PGF2α (d-cloprostenol 75 µg/mL; i.m. @ 75 µg /ewe) on day 09 and eCG (i.m. @ 300 IU/ewe) on day 11. Ewes were divided equally into four groups (n = 20 each) and then LAI was performed at 48 (T48), 60 (T60), 72 (T72) and 96 (T96) hours post-sponge removal using 200 million sperm/insemination. In Experiment 2, ewes (n = 81) were synchronised as in Experiment I. Following synchronisation ewes were divided into four groups, each subjected to LAI employing varying sperm concentrations: 10 (S10; n = 21), 20 (S20; n = 20), 50 (S50; n = 20), or 100 (S100; n = 20) million per insemination. Inseminations were performed within a time window of 48-60 h post-sponge removal, based on the findings from Experiment 1. In both experiments ewes were categorised according to BCS, that is, medium 3 and high > 3. Results of Experiment 1 revealed a quadratic response that ewes inseminated at 60-h post-sponge removal exhibited significantly higher pregnancy and twinning rates (p = 0.02). The results of Experiment 2 revealed that sperm concentration had a quadratic effect, 50 million sperm per insemination resulted in maximal pregnancy rates (p = 0.01). Additionally, ewes with medium BCS (≤ 3) had higher pregnancy rates than high BCS (> 3) ewes. In conclusion, ewes with medium BCS (≤ 3) are ideal candidate for LAI and can be inseminated at 60 h with minimal sperm 50 × 106/dose post-sponge removal to achieve a maximum pregnancy rate.

Experience of an Anatomic Femoral Stem in a United Kingdom Center - Excellent Survivorship and Negligible Periprosthetic Fracture Rates at Mean 12 Years Following Primary Total Hip Arthroplasty.

BACKGROUND: As the clinical burden of periprosthetic fractures (PPFs) continues to increase, it has been suggested that the use of anatomical femoral stems may help reduce PPF risk. The primary aim of this study was to determine the survivorship and PPF rate of an anatomical femoral stem in a single center at minimum 10-year follow-up. METHODS: A total of 1,000 consecutive total hip arthroplasties (THAs) performed using an anatomical femoral stem were identified from a prospectively collected arthroplasty database. Patient radiographs were reviewed finally at a mean of 12 years (range, 10 to 16 years) following surgery to identify any revision surgery, dislocations or PPFs. Mean patient age at surgery was 69 years (range, 24 to 93). There were 634 women (63%). Osteoarthritis was the operative indication in 946 patients (95%). RESULTS: All-cause THA survivorship was 99.1% (95% confidence interval (CI), 99.0-99.3%) at 10 years and 97.9% (CI, 97.8 - 98.0%) at 15 years. Stem survivorship at 10 years was 99.6% (CI, 99.5-99.7%) and at 15 years was 98.2% (CI, 98.1-98.3%). The 15-year stem survival for aseptic loosening was 100% with no cases of significant lysis found (lucent line >2mm). Implant survivorship was not significantly impacted by patient sex (P = .65), body mass index (P = .49), deprivation level (P = .284), operative indication (P = .33), or American Society of Anesthesiologists class (P = .374). There were 3 PPFs identified (0.3%) at mean 12-year follow-up and 15 dislocations (1.5%). CONCLUSION: This anatomical femoral stem demonstrated excellent survivorship and negligible PPF rates at mean 12-year follow-up following primary THA.

Glyphosate in the environment: interactions and fate in complex soil and water settings, and (phyto) remediation strategies.

Glyphosate (Gly) and its formulations are broad-spectrum herbicides globally used for pre- and post-emergent weed control. Glyphosate has been applied to terrestrial and aquatic ecosystems. Critics have claimed that Gly-treated plants have altered mineral nutrition and increased susceptibility to plant pathogens because of Gly ability to chelate divalent metal cations. Still, the complete resistance of Gly indicates that chelation of metal cations does not play a role in herbicidal efficacy or have a substantial impact on mineral nutrition. Due to its extensive and inadequate use, this herbicide has been frequently detected in soil (2 mg kg-1, European Union) and in stream water (328 µg L-1, USA), mostly in surface (7.6 µg L-1, USA) and groundwater (2.5 µg L-1, Denmark). International Agency for Research on Cancer (IARC) already classified Gly as a category 2 A carcinogen in 2016. Therefore, it is necessary to find the best degradation techniques to remediate soil and aquatic environments polluted with Gly. This review elucidates the effects of Gly on humans, soil microbiota, plants, algae, and water. This review develops deeper insight toward the advances in Gly biodegradation using microbial communities. This review provides a thorough understanding of Gly interaction with mineral elements and its limitations by interfering with the plants biochemical and morphological attributes.

Risk factors for femoral stem fracture following total hip arthroplasty: a systematic review and meta analysis.

BACKGROUND: Femoral stem fracture following total hip arthroplasty (THA) is an infrequent but nevertheless devastating complication, with an increasing worldwide prevalence as demand for primary THA continues to increase. The aim of this study was to perform a systematic review and meta-analysis of risk factors for femoral stem fracture to help identify at risk patients. METHODS: A systematic search was conducted on EMBASE, MEDLINE and AMED to identify relevant studies. Data regarding study design, source, population, intervention, and outcomes was collated. Data extraction was performed on a custom form generated using Cochrane recommended methodology and analysis of risk factors performed including odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: A total of 15 studies reporting a total of 402 stem fractures in 49 723 THAs were identified. The median time from index procedure to stem fracture was 68 months (IQR 42.5-118) whilst mean age at index surgery was 61.8 years (SD 6.9). Male gender (OR = 3.27, 95% CI = 2.59-4.13, p < 0.001), patient weight above 80 kg (OR = 3.55, 95% CI = 2.88-4.37, p < 0.001), age under 63 years (OR = 1.22, 95% CI = 1.01-1.49, p < 0.001), varus stem alignment (OR = 5.77, 95% CI = 3.83-8.7, p < 0.001), use of modular implants (OR = 1.95, 95% CI = 1.56-2.44, p < 0.01) and undergoing revision arthroplasty (OR = 3.33, 95% CI = 2.70-4.1, p < 0.001) were significant risk factors for prosthetic stem fracture. A risk window of 15 years post-surgery was identified. CONCLUSIONS: This review concludes that patient weight, younger age, male sex, varus stem alignment, revision arthroplasty and use of modular stems are significant risk factors for femoral stem fracture. Modifying these risk factors where possible may help reduce incidence of femoral stem fracture in at risk patients.

What factors influence patient autonomy in healthcare decision-making? A systematic review of studies from the Global South.

BACKGROUND: The principle of respect for autonomy (PRA) is a central tenet of bioethics. In the quest for a global bioethics, it is pertinent to ask whether this principle can be applied as it is to cultures and societies that are devoid of the Western sociopolitical historical pressures that led to its emergence. Relational autonomists have argued for a more inclusive approach to patient autonomy which takes into account factors such as interdependency and social relations. However, at the outset of any relational approach, it is necessary to identify underlying factors that influence patient autonomy in non-Western cultures. OBJECTIVE: To conduct a review of the literature to uncover the mechanisms through which social, cultural, and religious factors influence and impact the application of the PRA in healthcare decision-making in non-Western cultures and societies. METHODS: We conducted a systematic review through a comprehensive search of three major electronic databases of biomedical sciences. Returned citations were imported to Covidence, full texts were assessed for eligibility, included articles were thoroughly reviewed and data was synthesized. PRISMA guidelines were followed. RESULTS: Our search retrieved 590 non-duplicate results, 50 of which were included after screening and full-text eligibility checks. The included studies were predominantly qualitative in nature, with few quantitative, mixed-methods, and review studies included. Our synthesis of data identified nine key factors that influenced patients' autonomous decision-making through cultural, social, religious, or intersectional pathways. CONCLUSION: Two main conclusions emerge from this review. Firstly, there is a notable dearth of bioethical research examining the influence of diverse factors on patients' inclination towards different conceptions of autonomy. Secondly, the analysis of prevalent collectivist cultures and deference of autonomy adds value to the solution-oriented relational autonomy debate. This raises questions regarding how decision-making can be truly autonomous in the presence of such large-scale factors, warranting further attention.

Available literature highlights the pharmaceutical potential of oleuropein against various diseases such as obesity, diabetes, cardiovascular complications, neurodegenerative diseases, cancer, inflammation, microbial infections, and oxidation. This review will benefit the scientific community as it narrates comprehensive literature regarding absorption, metabolism, bioavailability, extraction techniques, and nutraceutical perspectives associated with oleuropein.

Prime editing: A potential treatment option for ß-thalassemia.

The potential to therapeutically alter the genome is one of the remarkable scientific developments in recent years. Genome editing technologies have provided an opportunity to precisely alter genomic sequence(s) in eukaryotic cells as a treatment option for various genetic disorders. These technologies allow the correction of harmful mutations in patients by precise nucleotide editing. Genome editing technologies such as CRISPR (clustered regularly interspaced short palindromic repeat) and base editors have greatly contributed to the practical applications of gene editing. However, these technologies have certain limitations, including imperfect editing, undesirable mutations, off-target effects, and lack of potential to simultaneously edit multiple loci. Recently, prime editing (PE) has emerged as a new gene editing technology with the potential to overcome the above-mentioned limitations. Interestingly, PE not only has higher specificity but also does not require double-strand breaks. In addition, a minimum possibility of potential off-target mutant sites makes PE a preferred choice for therapeutic gene editing. Furthermore, PE has the potential to introduce insertion and deletions of all 12 single-base mutations at target sequences. Considering its potential, PE has been applied as a treatment option for genetic diseases including hemoglobinopathies. ß-Thalassemia, for example, one of the most significant blood disorders characterized by reduced levels of functional hemoglobin, could potentially be treated using PE. Therapeutic reactivation of the γ-globin gene in adult ß-thalassemia patients through PE technology is considered a promising therapeutic strategy. The current review aims to briefly discuss the genome editing strategies and potential applications of PE for the treatment of ß-thalassemia. In addition, the review will also focus on challenges associated with the use of PE.
