Abstract

 

The Red sea has specific unique different features capturing rich biodiversity and aquatic species. The most important geographical and biological values focused on coral reef ecosystems. The shallow regions, as well as the island of Farasan and the tiny islands scattered around it, provide a suitable area for the coral reef distribution and nurture many endemic creatures. This review relied on coral reef association and classification. It dealt with the Red Sea problem and nature with relation to coral reef properties and its impacts. It focused on coral reef threats with future view for economical tourism based on role of coral reefs besides ways for coral reefs conservation. It comprised notes on coral predation, bleaching and diseases. The major hurdle to the coral reefs of this region, resulting in wider areas of coral bleaching, is the rise in temperature due to the global warming phenomenon. This work emphasizes the extent and diversity of red sea corals’ natural and anthropogenic issues faced by the coral ecosystems based on published research and technical reports with scoring reviewed data accompanied with tables and figures. Bar and pie graphs were used to analyze the coral reef data to interpret the actual status for all types presented in different countries. At the end of this investigation, conclusion and prediction of coral reefs status besides recommendations for sustainable development applied on utilization of coral reefs were performed.

Abstract

 

Lipid-polymer hybrid nanoparticles (LPHNPs) are innovative composite structures featuring a core-shell design, with a polymeric nanoparticle core surrounded by PEGylated lipid layers. This architecture combines liposome circulation with nanoparticle strength, offering a promising solution for multidrug-resistant cancers. The current study aimed to develop an integrated platform that leverages these advantageous characteristics. To achieve this, Tamoxifen-loaded nanoparticles were formulated using emulsion solvent evaporation technique with PLGA poly (lactic-co-glycolic) acid polymer, while Doxycycline-containing liposomes were developed through a film hydration method. These two components were then combined to fabricate LPHNPs. A range of physicochemical and structural analyses, including dynamic light scattering (DLS), laser diffraction analysis (LDA), and scanning electron microscopy (SEM), were performed. Cellular cytotoxicity was quantitatively assessed using the MTT assay, and biocompatibility was evaluated through in vivo acute toxicity tests on female albino mice. The average hydrodynamic sizes of Tamoxifen and Doxycycline formulations were 198.80 ± 2.10 nm and 100.5 ± 1.29 nm, respectively. After coating Tamoxifen nanoparticles with Doxycycline liposomes, resultant LPHNPs exhibited a diameter of 200.4 ± 2.51 nm and a zeta potential of 4.45 ± 2.51 mV. Notably, LPHNPs demonstrated a significant increase in cytotoxicity (p < 0.001) and showed reduced in vivo toxicity compared to free drugs, with no discernible toxicity observed in histopathology of vital organs, confirming their safety and efficacy.

Abstract

 

Tacca (Tacca leontopetaloides (L.) Kuntze) is a tuberous plant commonly growing in coastal areas, both in open and shaded areas. This study aimed to identify the agronomical characteristics and metabolite content of Tacca growing under various levels of natural shading. The research was conducted in the southern coastal area of Garut Regency (West of Java-Indonesia) by observing the plant growth and production, and metabolite content of Tacca tubers under conditions of natural full sunlight (0% shade/FL), moderate shade (40% shade/MS), and heavy shade (75% shades/HS) in three different locations as replications. Three mature plants (±7 months old) in each shade level and replication were randomly selected as observed samples. The result presented that Tacca’s growth increased with the increasing shading levels. Nonetheless, tuber production showed the highest value under MS, which increased by 76.64% and 35.20% compared to FL and HS, respectively. Fourteen metabolites were detected in Tacca tuber grown in MS and FL, while only eight metabolites were detected in HS. The highest concentration of the metabolites obtained in MS were 8 metabolites (57%) and followed by FL and HS with 3 (21%) and 1 metabolite (7%), respectively. Moderately shaded areas have great potential to be used as cultivation land to produce high-quality Tacca tubers.

Abstract

Vibrating sample magnetometry (VSM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) were used to characterize iron oxide nanoparticles (IONPs) synthesized via co-precipitation. TEM showed that the synthesized NPs had an average size of 13.8 nm and exhibited a saturation magnetization of 50.26 emu/gm, while XRD confirmed their crystallinity. This study assessed the toxicological impacts of IONPs on hematology, serum biochemistry, genotoxicity, and the histoarchitecture ailments in different visceral organs (liver, kidneys, spleen, brain, and heart of rabbits (Oryctolagus cuniculus). A total of 16 healthy adult rabbits without infections were randomly assigned to two groups (A and B). Group A was the control whereas group B received 0.5 mg/kg bw of IONP dose once for 10 days via marginal ear vein. Visceral tissues and blood were obtained from each rabbit on days 5 and 10 of trial. The results showed a significant reduction in antioxidant enzymes and an increase in oxidative stress. The hematological profile indicated lower values of red blood cell counts, hematocrit, lymphocyte, and monocyte while significantly higher values of total white blood cell counts and neutrophil (%) in IONPs-treated rabbits. Serum biomarkers of the liver, kidneys, and heart exhibited escalated concentrations in IONPs-treated rabbits. Histopathological examination revealed notable tissue alterations like necrosis of hepatocyte, congestion, and bile duct hyperplasia in the liver, neuronal degeneration, necrosis, and microgliosis in the brain, tubular degeneration, necrosis, and congestion in the kidneys and disorganization of cardiac myofibers and edema in cardiac tissue. A significantly increased DNA damage was assessed in multiple visceral organs of treated rabbits. In conclusion, our findings demonstrate that exposure to IONPs induces toxic effects in multiple visceral organs including the kidneys, liver, spleen, heart, and brain in rabbits.

Abstract

 

The Shisham (Dalbergia sissoo) population is threatened by the fungal pathogens causing dieback disease. Research over the past decade has shown the involvement of multiple fungal pathogens in causing the dieback disease. Here we reported the RAPD-PCR-based genetic diversity in three potential fungal pathogens including Botrydiplodia theobromae, Fusarium solani, and F. oxysporum isolated from diseased plants across the Punjab province in Pakistan. Twenty fungal isolates of three major fungal species were isolated from dieback-infected trees from eight districts in Punjab Pakistan to investigate the genetic diversity with a set of fifteen RAPD markers of OPB, OPK, and OPL series.  Consequently, fifteen markers produced 166 loci with an average of 55.33 loci per population. Of these, 76.31% loci were polymorphic highlighting the presence of abundant genetic diversity in pathogens. Moreover, OPK-06 primer showed a higher PIC value of 0.416 along with higher heterozygosity contents of 0.49. However, population structure analysis of each fungal strain grouped similar and dissimilar ones based on their amplification into the same and different clusters respectively. The isolates of B. theobromae of the Ayub Agriculture Research Institute (AARI) and Attock district showed higher genetic distance (0.6812) and were found in different clusters. Similarly, isolates of F. solani from UAF formed a different group which further highlighted its degree of polymorphism. Moreover, the UAF isolate displayed a maximum of 0.6432 genetic distance from the AARI isolate. Conversely, the isolates of F. oxysporum were grouped into two main groups highlighting the limited genetic diversity. Further, isolates from UAF also exhibited a maximum of 0.7372 genetic distance from AARI. Consistent results of UAF and AARI isolates of F. oxysporum and F. solani are suitable grounds for further genetic studies.

Abstract

 

Cryptococcus neoformans is an opportunistic fungal pathogen, especially affecting individuals with weakened immune systems. Laccase enzymes are pivotal in its pathogenicity, making them promising targets for therapeutic intervention. This study aims to identify and characterize potent laccase inhibitors against C. neoformans using advanced in-silico analysis. The laccase protein (UniProt ID: Q55P57) was retrieved via AlphaFold and validated with ProCheck. Pharmacophore-based virtual screening (PBVS) identified 19 potential inhibitors, which were docked using CB-Dock2. The top six compound’s pharmacokinetic properties were assessed using SwissADME, PKCSM, and StopTox. Bioactivity was predicted via SwissTargetPrediction. Density Functional Theory (DFT) calculations were conducted using Gauss view 5.0.8. The validated 3D structure of the target protein Q55P57 demonstrated high quality, with 86.5% of residues in favored regions. The molecular docking revealed that L-11 exhibited the highest binding affinity (-13.2 kcal/mol), forming crucial interactions within the active site. L-11 displayed favorable physicochemical properties, including high lipophilicity and good Caco2 permeability, positioning it as a strong candidate for therapeutic development. Toxicity predictions indicated non-toxicity for acute inhalation and oral exposure, while bioactivity analysis highlighted its broad target interactions. DFT analysis demonstrated L-11’s enhanced reactivity due to its high dipole moment and low HOMO-LUMO energy gap. The identification of L-11  (8-[4-[9,9-Dimethyl-7-(2,3,4,5,6,7,8,9,10-nonahydroxypyren-1-yl)fluoren-2-yl]phenyl]pyrene-1,2,3,4,5,6,7,9,10-nonol) as a potent inhibitor of C. neoformans laccase represents a novel approach to antifungal drug discovery, marking a significant step to combat fungal infections and a way forward to perform in-vitro and in-vivo studies and ultimately its clinical application.

Abstract

 

Dioecious plants, like Date palm (Phoenix dactylifera) and Jojoba (Simmondsia chinensis), are a type of plant that do not have sexual identification in the same way that animals or humans do. Sexual identification in plants typically involves determining the sex of individual plants within a dioecious species. Date palms and jojoba are dioecious, with male and female trees, and their sexual identification is important in agriculture for proper pollination, but until now it doesn’t involve methods like RPA (Recombinase Polymerase Amplification) or CRISPR. We successfully developed a CRISPR/Cas12a-based fluorescence test for the sexual identification of date palm and jojoba as models for dioecious, with RPA and CRISPR-Cas12a, which could be used as a simple, accurate, and fast detection method in agricultural fields due to its advantages of high-sensitivity. This investigation uses our proprietary technology to detect sub-kilobase non-repetitive genomic loci, CRISPR-FISH. In this study, we designed 16 different sgRNAs using full-length Human SRY as the substitute target in date palm and jojoba, given the extremely high homology between Human SRY and Date Palm SRY gene. These sgRNAs were labeled them 3 Atto565 dyes per sgRNA to visualize them at a single-cell level. Fluorescence in situ hybridization (FISH) has been employed as a potent and practical method for directly identifying certain DNA segments inside the genome. In this method, plant chromosomes are physically mapped using ribosomal DNA genes (45S and 5S rDNA) as markers to examine genomic organization. The initial result for SRY staining in a substitute cell line, the Human A549 cell, a male cell line containing a single copy of SRY was promising albeit with high background staining. Prominent dots (red) in the nuclei region were observed, but with high background staining in both nuclei and cytosol. This refined technique is perfect for quickly localizing tiny DNA segments and single-copy genes. Additionally, PRINS is a quicker and less expensive option than FISH. Furthermore, the successful application of the assay for Sexual identification of some Dioecious plant samples highlighted its potential for rapid and accurate sex detection in agricultural settings. In summary, this RPA-CRISPR/Cas12a diagnostic method offers a potentially valuable technological solution and management for Dioecious plant sex-determination at very early stage.
