Morpho-physiological and biochemical characterization of Kinnow (Citrus reticulata) in response to canker pathogens (Xanthomonas axonopodis pv. citri)

Fruits play an important role in human life on our planet, since they supply a variety of essential services. One of the paramount crops in Pakistan is Citrus reticulata (Kinnow), which plays a vital role in the country's economy. The citrus crops are confronted with various challenges such as fungi, bacteria, nematodes, and viruses, all of which have adverse effects on the quality and yield of the fruits. Citrus canker, in particular, stands as the most fatal disease, affecting numerous citrus species worldwide, inflicting devastating consequences. The objective of this study was to evaluate the impact of citrus canker on the morphology, physiology of leaves, and the quality of citrus fruits. The research was conducted in four major citrus-producing tehsils of the Sargodha district. The study found significant differences in morphological and physiological traits between healthy fruits and those infected with citrus canker. Healthy fruits exhibited higher values in fruit weight (FW) of 149.02 g, peel thickness (PT) of 3.76 g, rag weight (RW) of 35.95 g, leaf area (LA) of 22.49 cm2, and juice weight compared to the citrus canker-infected fruits. The significant variations in fruit weight, juice weight, chlorophyll content, vitamin C content were present between healthy and diseased fruits and leaves. A biochemical study revealed that healthy fruits had greater levels of total soluble solids (TSS), TSS-acid ratio, vitamin C, and reducing power (RP), but citrus canker-infected fruits had a higher acidity percentage. The significant decreases in important morphological and physicochemical characteristics, emphasizing the necessity for immediate disease control techniques to safeguard the citrus sector and maintain food security.

Efficacy and safety of hypertonic saline therapy in ambulatory patients with heart failure: The SALT-HF trial.

Combination of hypertonic saline solution (HSS) with intravenous loop diuretics has been suggested to improve diuretic response in patients hospitalized for heart failure (HF). The efficacy and safety of this approach in the ambulatory setting remain unexplored. In this multicentre, double-blind, randomized study, we allocated ambulatory patients with worsening heart failure (WHF) to a 1-h infusion of intravenous furosemide (ivFurosemide)-HSS versus ivFurosemide. The primary endpoint was the volume of diuresis at 3 h. Secondary endpoints included 3-h natriuresis and weight variation, 7-day congestion data, kidney function and electrolytes, and 30-day clinical events. Overall, 167 participants (median age: 81 years, 30.5% female) were randomized across 13 sites between December 2020 and March 2023. There were no differences in 3-h diuresis between treatments (ivFurosemide-HSS: 1099 ml vs. ivFurosemide: 1103 ml, p = 0.963), 3-h natriuresis (∆ +2.642 mEq/L, p = 0.559), or 3-h weight (∆ +0.012 kg, p = 0.920). Patients in the ivFurosemide-HSS arm experienced significant weight decrease at 7 days (Δ -0.586 kg, p = 0.048). There were no between-treatment differences in clinical congestion score, biomarkers, inferior vena cava diameter, or the presence of lung ultrasound B-lines. At 30 days, 26.5% of the patients in the ivFurosemide-HSS group versus 33.3% in the ivFurosemide group experienced WHF (hazard ratio 0.76, p = 0.330). The incidence of death from any cause or HF hospitalization was 6% of patients in the ivFurosemide-HSS group and 8.3% of patients in the ivFurosemide group (hazard ratio 0.69, p = 0.521). The incidence of worsening kidney function or metabolic derangements was not significantly different in the two arms. A single infusion of ivFurosemide-HSS did not improve 3-h diuresis or congestion parameters in patients with ambulatory WHF. This therapy showed an appropriate safety profile.

Application of Open Panicle Traits in Improving the Filling Characteristics at the Base of Indica Rice Panicles.

Panicle-type structure is an important factor affecting rice yield, and an excellent panicle type has become a key indicator in rice breeding. In this study, the indica rice variety R766, which has an open panicle type, was obtained through natural mutation and hybrid selection. Through analyzing differences in panicle structure, panicle yield, and chemical composition between open panicle rice R766 and conventional panicle rice R2928, we found that the angles of the middle and lower branches in R766 were 186.99% and 135.93% greater than those in R2928, respectively. By comparing the grain-filling characteristics of different panicle positions in the two rice varieties, we found that the grain filling at the middle and lower panicle positions of R2928 was significantly lower, accompanied by an increase in the percentage of empty spikelets. However, in R766, the grain-filling rates in the middle and lower panicle positions were consistent with those in the upper panicle position, with significantly higher rates of grain filling and grain plumpness in the middle and lower panicle positions than in R2928. The empty grain rate at the lower panicle position of R766 was 15.25% lower than that of R2928, and the grain filling was 24.75% higher than that of R2928. Additionally, the variation in the 1000-grain weight of grains at different panicle positions in R766 was relatively small, with decreases of 1.55% and 0.38% in the middle and lower panicle positions, respectively, compared with the upper position, whereas R2928 showed decreases of 5.99% and 7.12% in the 1000-grain weight of grains at the middle and lower panicle positions, respectively, compared with the upper position. The cellulose content in the stems of R766 was 7.51% higher than that of R2928, with no significant difference in the cellulose content in the panicle axis and primary branches compared to R2928. The lignin content of the panicle axis in R766 was 8.03% higher than that in R2928, whereas there was no significant difference between the lignin content of the stems and primary branches. This preliminary study revealed the open panicle characteristics of R766 and the reasons for its high basal grain setting rate. This study provides a reference for promoting this open panicle-type indica rice variety to improve yield and disease resistance in environments with high humidity and low sunlight levels.

Synthesis of new pyrazine-pyrazole-thiazolidin-4-one and pyrazine-triazole-thiazolidin-4-one conjugates, molecular modelling and docking as antimicrobial agents

The ever-increasing incidence of microbial resistance provide a significant peril to the scientific community. Thus, the need for the discovery and development of new antimicrobial agents is becoming critical. An effective approach to address this challenging problem is to generate hybrid molecules by combining two or more pharmacophores covalently linked to a single-molecule platform. Antimicrobial hybrids have been proposed as promising solution to overcome drug resistance and/or presumably having a broader spectrum of activity. This guided us to synthesize a new series of eight final target pyrazine-pyrazole-thiazolidin-4-one and pyrazine-triazole-thiazolidin-4-one hybrids 7, 8a-c, 12, and 13a-c and investigate their biological activities. Characterization of the designed hybrids were performed using IR, 1H NMR, 13C NMR, and mass analyses. The DFT/B3LYP approach revealed that the synthesized hybrids had a non-planar configuration. The nitrobenzylidene derivatives 8c and 13c exhibited the highest polarizability and hyperpolarizability. We examined the antimicrobial activity, DNA gyrase inhibition, molecular docking, and Swiss ADME analysis of different pyrazine-pyrazole-thiazolidin-4-one and pyrazine-triazole-thiazolidin-4-one conjugates. These compounds are effective against a number of bacterial and fungal strains, suggesting possible treatments for certain infections. DNA gyrase inhibition experiments demonstrated that conjugate 13b was more effective than novobiocin. A molecular docking study sheds light on the binding affinities and interactions of these conjugates with target proteins, revealing strong and specific bindings for numerous conjugates. Swiss ADME studies examine important pharmacokinetic parameters and show issues with bioavailability and membrane permeability in the mouth because of variations in molecular weight, lipophilicity, and hydrogen bond interactions. Swiss ADME studies have studied the drug-like qualities of these conjugates, revealing their potential in antibacterial applications.

Variation in body weight, glucose/insulin tolerances, blood lipids and liver enzymes in mice in response to a high-fat-diet from lard

It raises questions about the impact of lard on the health and the differences in individual responses. Therefore, we developed a model of mice fed with high fat (HF) from lard in 130 days. The weight of the mice was measured every two days. Glucose tolerance test and insulin tolerance tests were performed at 70 days and 130 days of experiment. At the end of the study, the fat tissue was collected to check the weight, and a blood sample was collected to check the blood lipids and liver enzymes. Surprisingly, mice responded variously to the HF by being classified into two groups, one group had significantly high gained weight (HG_HF) versus the mice fed a standard diet (STD) (p < 0.001), and another group (LG_HF) has not difference in body weight compared to the STD groups. This phenomenon in body weight is directly reflected by the white fat accumulation, but not by brown fat. Eating HF from lard for a long time can disrupt glucose tolerance and cause dyslipidemia in mice, even in the LG_HF group, but can not disrupt insulin tolerance and cause liver enzyme disorders. In summary, our findings are a wake-up call for many cases where eating HF from lard does not gain weight and not increase the white fat storage, but still has the potential to cause adverse health effects. Further studies are encouraged to understand the molecular mechanisms that causes the body to regulate its weight and responses when eating HF from lard, especially in the LG_HF group.

Preparation and in vitro characterization of graphene oxide impregnated superporous hydrogel beads: an effective approach of gastro-retentive drug delivery system

ABSTRACT The remarkable properties of graphene oxide, a shining dynamo, opened new possibilities for delivering the drug. The present work aims to fabricate a graphene-based porous hydrogel system that fades its side effects and encourages its utilization as a drug carrier. Graphene oxide was impregnated in the polymeric matrix for gastro-retentive drug delivery. Porogen was added to create a superporous structure. The extrusion-dripping technique is used to fabricate low density, super porous, and floating hydrogel beads, which were considered a practical approach to target the drug in a controlled and sustained manner in the stomach. The fabricated graphene oxide impregnates superporous beads were characterized by physicochemical analysis, morphological parameters, PXRD, swelling study, drug-release pattern, and in-vitro floating ability. The homogenous nature of fabricated samples was analyzed by weight and size variation. Micrometric properties were estimated to calculate the density and flow ability of superporous beads. The stability and shelf life of prepared hydrogels were performed by accelerated stability analysis according to ICH guidelines. Doxorubicin was chosen as a model anticancer drug. The pi–pi stacking technique is responsible for a considerable loading of the drug onto graphene oxide (GO). However, the successful preparation of low-density graphene oxide impregnates superporous hydrogel beads shows excellent floating ability, thus making it a promising candidate for stomach targeting.

Photopolymerization of polyvinylethylene glycol oligomers by thiol‐ene click reaction

AbstractFunctional polyvinylethylene glycols (PVEGs) with pendent vinyl groups were synthesized by Pd/B synergistic catalysts and their structures were characterized by 1H NMR and FT‐IR. The photopolymerization of the obtained PVEGs with multifunctional thiols in the presence of a photoinitiator proceeded smoothly via thiol‐ene photo‐click reaction to give a series of crosslinked materials by the variation of the molecular weight of PVEGs and a ratio of thiols and enes. The curing behavior was studied by FT‐IR and the properties of crosslinked materials were characterized by the test of gel content, swelling ratio, and water absorption. The dynamic mechanical analysis, mechanical properties, thermogravimetry, and surface properties of the crosslinked materials were investigated and the performance of coating for the crosslinked film materials was also characterized. The crosslinked film materials can be further functionalized by post‐crosslinking modification through thiol‐ene photo‐click reaction.

Genomic patterns of selection in morphometric traits across diverse Indian cattle breeds.

This study seeks a comprehensive exploration of genome-wide selective processes impacting morphometric traits across diverse cattle breeds, utilizing an array of statistical methods. Morphometric traits, encompassing both qualitative and quantitative variables, play a pivotal role in characterizing and selecting livestock breeds based on their external appearance, size, and physical attributes. While qualitative traits, such as color, horn structure, and coat type, contribute to adaptive features and breed identification, quantitative traits like body weight and conformation measurements bear a closer correlation with production characteristics. This study employs advanced genotyping technologies, including the Illumina BovineSNP50 Bead Chip and next-generation sequencing methods like Reduced Representation sequencing, to identify genomic signatures associated with these traits. We applied four intra-population methods to find evidence of selection, such as Tajima's D, CLR, iHS, and ROH. We found a total of 40 genes under the selection signature, that were associated with morphometric traits in five cattle breeds (Kankrej, Tharparkar, Nelore, Sahiwal, and Gir). Crucial genes such as ADIPDQ, DPP6, INSIG1, SLC35D2 in Kankrej, LPL, ATP6V1B2, CDC14B in Tharparkar, HPSE2, PLAG1 in Nelore, PCSK1, PRKD1 in Sahiwal, and GNAQ, HPCAL1 in Gir were identified in our study. This approach provides valuable insights into the genetic basis of variations in body weight and conformation traits, facilitating informed selection processes and offering a deeper understanding of the evolutionary and domestication processes in diverse cattle breeds.

Quality of medicines for Cardio-Vascular Diseases (CVDs) in the Ethiopian border with Kenya: The case of enalapril maleate and furosemide tablet quality in Borena and Gedeo zones.

Hypertension (HTN), a cardiovascular disease (CV), is a major public health challenge. Therefore, the quality of drugs used to treat it has become a major concern. Enalapril and furosemide are among the drugs prescribed to manage hypertension. Hence, this study is aimed at evaluating the quality of different brands of enalapril and furosemide tablets available in the Gedeo and Borena zones, southern Ethiopia. Thirteen generic brands of enalapril maleate (5 mg) and furosemide (40 mg) tablets were evaluated for visual defects, in vitro dissolution test, weight variations, friability, hardness, and disintegration tests. The analysis of active pharmaceutical ingredient (API) content was performed by high performance liquid chromatography (HPLC). Out of 55 samples, 7 (12.73%) failed to comply with the criteria for visual inspection; otherwise, all samples passed the identification test. Except for one brand of each of enalapril maleate and furosemide, all passed the dissolution test. The assay value showed that all enalapril maleate samples were within the limits of United States Pharmacopoeia (USP), 2020. Additionally, except for two batches, all furosemide samples were within the USP and British Pharmacopoeia (BP), 2020 standards. Out of 55 samples, 8% (2/25) and 6.67% (2/30) of enalapril maleate and furosemide tablets failed the uniformity of dosage units test per the USP-2020, respectively. All samples passed the disintegration test, and selected furosemide samples passed the microbial limit tests. However, 36% (9/25) and 20% (6/30) of enalapril maleate and furosemide samples failed to pass hardness test. Generally, from the total samples, 50.91% (28/55) were substandard (did not meet the specifications failing any one or more parameters assessed). The studied drugs circulating in the market did not meet some of the needed quality specifications. This could have brought a risk of reduced efficacy due to the distribution of poor quality medicines in the area.

Teneligliptin hydrobromide hydrate mouth dissolving strip: Formulation and evaluation

Oral route is considered as one of the most convenient route for administration of various pharmaceutical dosage form like tablet, capsule, syrup, suspension and emulsion. Fast Dissolving Drug Delivery systems have developed various fast disintegrating preparations like Oral disintegrating film, ODF. Oral disintegrating film is the solid oral drug delivery system, in which water soluble polymer involve to disintegrate film into mouth fastly. Oral disintegrating film is superior as compare to orally disintegrating tablet as the cost of production is low. The present research was undertaken to develop oral disintegrating film of tteneligliptin hydrobromide hydrate to have rapid onset of action. of tteneligliptin hydrobromide hydrate which is an anti-diabetic. The mechanism action of Teneligliptin is to increase incretin levels (GLP-1 and GIP), which inhibit glucagon release, which in turn increases insulin secretion, decreases gastric emptying, and decreases blood glucose levels.The concept of formulating fast disintegrating film Teneligliptin containing offers a suitable and practical approach in serving desired objective of faster disintegration and dissolution characteristics with increased bioavailability. ODF of Teneligliptin were prepared by solvent casting method and evaluated physicochemical parameters like thickness, weight variation, moisture content, folding endurance, drug content, etc. All the formulations of Teneligliptin ODF displayed optimum folding endurance, which indicates the formulation prepared can withstand handling and transportation. From the results obtained, it was concluded that the formulation of oral disintegrating film has better physical chemical properties with good disintegration property.

Treatment-emergent symptoms during short-term ketamine administration in treatment-resistant bipolar depression: A retrospective cross-sectional descriptive study

Symptoms that emerge during pharmacological treatment of bipolar depression are frequently observed, underscoring the necessity for comprehensive treatment monitoring. This observational study sought to observe the correlation of eight intravenous ketamine infusions with treatment-emergent depressive symptoms in treatment-resistant bipolar depression patients who maintained their baseline psychotropic and chronic somatic treatments. Depressive symptoms were evaluated using the Inventory of Depressive Symptomatology Self-Report 30 (IDS-SR30). Treatment-emergent symptoms TES were defined as symptoms absent at baseline but present at the conclusion of the study. The most common TES included decreased appetite, increased weight, hypersomnia, and diurnal mood variation. Conversely, feelings of sadness, altered perceptions of the future, decreased interest in sex, and physical discomfort were absent in all patients. Notably, 13.6 % of patients reported thoughts of death or suicide. Larger-scale studies, integrating clinician-rated and patient-reported outcome measures, are essential to deepen our understanding of treatment-emergent symptoms. Establishing regulatory or professional definitions for treatment-emergent symptoms is warranted to improve the robustness of future research endeavors.

Quality by design-based development and in vitro evaluation of dual release tablet of etoricoxib and thiocolchicoside: A novel chronotherapeutic approach for arthritis pain management

The traditional drug delivery system is not much effective when treating chronopathological diseases like arthritis. Consequently, there is a gap in the market for a delivery system that can provide an explicit treatment following the chronopharmacology of this disorder. The present study is based on the objective to develop Eudragit coated dual release bilayer tablet designed by the quality by design (QbD) and based on the chronotherapeutic approach. The dual release tablet contained an immediate release layer of etoricoxib and a sustained release layer of thiocolchicoside. The quality target product profile (QTTP) of the formulation was established along with critical quality attributes (CQA). The optimization of the dual release layer was done using a three-level, three-factor Box-Behnken design. A total of thirteen formulations of etoricoxib (ET1-ET13) and thiocolchicoside (TH1-TH13) were developed based on the design composition of etoricoxib, sodium starch glycolate and sodium bicarbonate for the immediate release (IR) layer and thiocolchicoside, HPMC E5 LV and magnesium stearate for the sustained release (SR) layer respectively. The developed dual release layers were compressed to form a bilayer tablet. The bilayer tablets were further coated with pH-dependent polymer Eudragit S-100 to avoid drug release in upper GIT. The initial characterization and drug-excipient interaction studies were performed initially using infra-red (IR) spectroscopy and X-ray diffraction studies (XRD). Formulations showing good micrometric properties, disintegration and drug release were selected for final compression of bilayer tablets. Formulation ET13 showed the fastest drug release (88%) at 15minutes and quick disintegration time (21s). The sustained release thiocolchicoside tablet layer (TH1-TH13) had a hardness that varied from 4.01 to 4.45kg/cm2. Formulation TH12 had the highest hardness, whereas TH6 showed the lowest hardness. The sustained release layer showing 97.63% of drug release after 8hours was selected for the compression to bilayer tablet. The developed dual layer tablets were investigated for quality parameters like hardness, percentage friability, weight variation, disintegration and dissolution. A high level of patient compliance is ensured through the current design as the patient does not need to get out of bed at night to take the medication.

Integrating Plastic Waste into Concrete: Sustainable Solutions for the Environment.

Plastic waste management has received significant attention in recent decades due to the urgent global environmental crisis caused by plastic pollution. The versatile and durable nature of plastic has led to its widespread usage across various sectors. However, its nonbiodegradable nature contributes to unsustainable production practices, leading to extensive landfill usage and posing threats to marine ecosystems and the food chain. To address these environmental concerns, numerous challenges have been recently addressed through investigating alternative approaches for disposing of plastic waste, with the construction sector emerging as a promising option. Incorporating plastic waste materials into concrete not only offers economic benefits but also provides a valid alternative to conventional disposal methods. This paper presents the results of different experimental studies, some of them available in the literature and others new, discussing the feasibility of integrating plastic waste into concrete and its impact on mechanical properties. The influence of different sizes, natures, treatments, and percentages of plastic waste in the concrete mixtures is dealt with in order to provide further data for helping to understand the nonunivocal results in the literature, under the conviction that only further observations can help to understand the mechanics of concrete with plastic aggregates. The experimental investigation highlighted that one parameter that is better than others and can be considered to compare different experimental investigations is the variation in weight (due to the effective volume of plastics in the mix), determining a sort of increasing of porosity that degrades the mechanical characteristics. However, this seems inconsistent in some cases. Therefore, the need for further research is highlighted to refine production methods and optimize mix designs.

Across two continents: The genomic basis of environmental adaptation in house mice (Mus musculus domesticus) from the Americas.

Replicated clines across environmental gradients can be strong evidence of adaptation. House mice (Mus musculus domesticus) were introduced to the Americas by European colonizers and are now widely distributed from Tierra del Fuego to Alaska. Multiple aspects of climate, such as temperature, vary predictably across latitude in the Americas. Past studies of North American populations across latitudinal gradients provided evidence of environmental adaptation in traits related to body size, metabolism, and behavior and identified candidate genes using selection scans. Here, we investigate genomic signals of environmental adaptation on a second continent, South America, and ask whether there is evidence of parallel adaptation across multiple latitudinal transects in the Americas. We first identified loci across the genome showing signatures of selection related to climatic variation in mice sampled across a latitudinal transect in South America, accounting for neutral population structure. Consistent with previous results, most candidate SNPs were in putatively regulatory regions. Genes that contained the most extreme outliers relate to traits such as body weight or size, metabolism, immunity, fat, eye function, and the cardiovascular system. We then compared these results with the results of analyses of published data from two transects in North America. While most candidate genes were unique to individual transects, we found significant overlap among candidate genes identified independently in the three transects. These genes are diverse, with functions relating to metabolism, immunity, cardiac function, and circadian rhythm, among others. We also found parallel shifts in allele frequency in candidate genes across latitudinal gradients. Finally, combining data from all three transects, we identified several genes associated with variation in body weight. Overall, our results provide strong evidence of shared responses to selection and identify genes that likely underlie recent environmental adaptation in house mice across North and South America.

Effects of Steviol Glycosides on Growth Performance, Ruminal Fermentation and Microbial Diversity of Hu Sheep.

The experiment was conducted to investigate the potential effects of steviol glycosides on growth performance, rumen fermentation processes, and microbial diversity in Hu sheep. A single-factor design was used for the trial. Twenty healthy weaned Hu lambs, possessing comparable body weights averaging 18.31 ± 1.24 kg, were randomly allocated into two distinct groups: the control group (CON) and the experimental group (STE), with each comprising 10 lambs. The CON was fed the basal diet, and the STE was supplemented with 0.07% steviol glycosides based on the basal diet. During the experimental period, variations in body weight and feed intake were closely monitored and recorded. After feeding for 90 d, blood was collected to determine blood biochemical indices, and rumen fluid samples were gathered for an in-depth analysis of rumen fermentation parameters and microbial diversity. The outcomes revealed no statistically significant differences in growth performance or serum biochemical indices between the two groups (p > 0.05). Rumen pH in STE and CON was within the normal range. The rumen ammonia nitrogen (NH3-N) and acetic acid (AA) content of STE decreased significantly compared with CON (p < 0.05). No significant variations were observed in the levels of other volatile fatty acids (VFAs) between the two groups (p > 0.05). The rumen microbial OTUs count, as well as the Shannon, Simpson, Chao1, and Ace indices, were notably lower in the STE group compared to the CON group (p < 0.05). Additionally, at the phylum level, the relative abundance of Firmicutes, Bacteroidetes, and Proteobacteria collectively accounted for over 97% of the total phylum composition. In comparison to the CON group, the STE group exhibited an increase in the relative abundance of Proteobacteria (p < 0.05), accompanied by a significant reduction in the relative abundance of Patescibacteria and Desulfobacteria (p < 0.05). At the genus level, there was a notable increase in the relative abundance of Prevotella_7 and Succinivibrionaceae_UCG_001 in the STE group, whereas the relative abundance of Rikenellaceae_RC9_gut_group significantly decreased (p < 0.05). According to the correlation analysis between rumen microflora and VFAs, the relative abundance of Succinivibrionaceae_UCG_001 displayed a significant negative correlation with AA (p < 0.05), whereas Lactobacillus exhibited a notable positive correlation with isobutyric acid (IBA) (p < 0.05). In summary, steviol glycosides had no significant effect on the production performance and blood biochemical indexes of Hu sheep. Steviol glycosides can improve rumen fermentation parameters and rumen microflora structure of Hu sheep and have a certain effect on rumen microbial diversity and composition.

Anti-Microbial, Thermal, Mechanical, and Gas Barrier Properties of Linear Low-Density Polyethylene Extrusion Blow-Molded Bottles.

Microbial contamination can occur on the surfaces of blow-molded bottles, necessitating the development and application of effective anti-microbial treatments to mitigate the hazards associated with microbial growth. In this study, new methods of incorporating anti-microbial particles into linear low-density polyethylene (LLDPE) extrusion blow-molded bottles were developed. The anti-microbial particles were thermally embossed on the external surface of the bottle through two particle deposition approaches (spray and powder) over the mold cavity. The produced bottles were studied for their thermal, mechanical, gas barrier, and anti-microbial properties. Both deposition approaches indicated a significant enhancement in anti-microbial activity, as well as barrier properties, while maintaining thermal and mechanical performance. Considering both the effect of anti-microbial agents and variations in tensile bar weight and thickness, the statistical analysis of the mechanical properties showed that applying the anti-microbial agents had no significant influence on the tensile properties of the blow-molded bottles. The external fixation of the particles over the surface of the bottles would result in optimum anti-microbial activity, making it a cost-effective solution compared to conventional compounding processing.
