Effect of fenugreek and flaxseed polysaccharide-based edible coatings on the quality attributes and shelf life of apple fruit during storage.

The present study was designed to explore the potential of fenugreek and flaxseed polysaccharide-based edible coatings to enhance the postharvest storage life of apple fruit. The experimental plan involved the preparation of five different coating formulations, which were subsequently applied to the fruit. The coated fruit was then stored at a temperature of 25 ± 2°C for a duration of 35 days. The effects of these coatings on physicochemical and biochemical attributes (weight loss, firmness, acidity, pH, sugar content, antioxidant activity, microbial growth, and sensory properties) of coated and uncoated samples were evaluated at regular intervals: 0, 7, 14, 21, 28, and 35 days of storage. The experimental results revealed a significant difference (p ≤ .05) in the physicochemical parameters of uncoated and coated apple at different storage times. The coated apple fruits showed significantly (p ≤ .05) lower weight loss, pH, total sugars, total soluble solids, and maximum retention of ascorbic acid, firmness, acidity, and antioxidant contents, leading to enhanced organoleptic properties. The application of edible coatings extended the shelf-life of the apples by inhibiting microbiological spoilage without substantial impact on sensory and nutritional properties. Based on these results, it is concluded that the edible coating formulation labeled T 1 (containing 2.5 g fenugreek polysaccharide and 1.5 g flax polysaccharide) effectively preserved the valuable physicochemical and organoleptic characteristics of the apple fruit throughout the storage period.

Efficacy of a vaginal suppository formulation prepared with Acacia arabica (Lam.) Willd. gum and Cinnamomum camphora (L.) J. Presl. in heavy menstrual bleeding analyzed using a machine learning technique.

Objective: This study aims to determine the efficacy of the Acacia arabica (Lam.) Willd. and Cinnamomum camphora (L.) J. Presl. vaginal suppository in addressing heavy menstrual bleeding (HMB) and their impact on participants' health-related quality of life (HRQoL) analyzed using machine learning algorithms. Method: A total of 62 participants were enrolled in a double-dummy, single-center study. They were randomly assigned to either the suppository group (SG), receiving a formulation prepared with Acacia arabica gum (Gond Babul) and camphor from Cinnamomum camphora (Kafoor) through two vaginal suppositories (each weighing 3,500 mg) for 7 days at bedtime along with oral placebo capsules, or the tranexamic group (TG), receiving oral tranexamic acid (500 mg) twice a day for 5 days and two placebo vaginal suppositories during menstruation at bedtime for three consecutive menstrual cycles. The primary outcome was the pictorial blood loss assessment chart (PBLAC) for HMB, and secondary outcomes included hemoglobin level and SF-36 HRQoL questionnaire scores. Additionally, machine learning algorithms such as k-nearest neighbor (KNN), AdaBoost (AB), naive Bayes (NB), and random forest (RF) classifiers were employed for analysis. Results: In the SG and TG, the mean PBLAC score decreased from 635.322 ± 504.23 to 67.70 ± 22.37 and 512.93 ± 283.57 to 97.96 ± 39.25, respectively, at post-intervention (TF3), demonstrating a statistically significant difference (p < 0.001). A higher percentage of participants in the SG achieved normal menstrual blood loss compared to the TG (93.5% vs 74.2%). The SG showed a considerable improvement in total SF-36 scores (73.56%) compared to the TG (65.65%), with a statistically significant difference (p < 0.001). Additionally, no serious adverse events were reported in either group. Notably, machine learning algorithms, particularly AB and KNN, demonstrated the highest accuracy within cross-validation models for both primary and secondary outcomes. Conclusion: The A. arabica and C. camphora vaginal suppository is effective, cost-effective, and safe in controlling HMB. This botanical vaginal suppository provides a novel and innovative alternative to traditional interventions, demonstrating promise as an effective management approach for HMB.

Early versus standard management of chimeric antigen receptor therapy toxicities and management's impact on safety and efficacy.

BACKGROUND: Cytokine release syndrome (CRS) and immune effector cell-associated neurologic syndrome (ICANS) are well-documented toxicities of CAR T-cell therapy. To mitigate excessive toxicity, our center has formulated treatment protocols (early vs. standard) for timely management of CRS and ICANS with tocilizumab and/or corticosteroids. METHODS: This retrospective, single-center analysis included patients treated with CAR T-cell therapy. The goal was to describe the association of two management protocols with toxicity and efficacy outcomes. RESULTS: Fifty-five percent of the 40 patients assigned to early management, out of which 5% and 9% developed grade 3+ CRS and ICANS, respectively. Seventy-seven percent and 41% of these patients received tocilizumab and corticosteroids, respectively. Forty-five percent of patients were stratified as standard management, out of which 0% and 11% developed grade 3+ CRS and ICANS, respectively. Seventeen percent and 28% of these patients received tocilizumab and corticosteroids, respectively. The day +90 overall response rate (ORR) for all patients was 63%, with an ORR of 89% for those managed per early management versus 50% for those managed per standard protocol. CONCLUSION: Early use of tocilizumab and corticosteroids is effective in preventing excessive CAR-T-related toxicities with no negative impact on efficacy.

Assessing the impact of discordant antibiotic treatment on adverse outcomes in community-onset UTI: a retrospective cohort study.

OBJECTIVES: To investigate the risk of adverse outcomes following discordant antibiotic treatment (urinary organism resistant) for culture-confirmed community-onset lower urinary tract infection (UTI). METHODS: Cohort study using routinely collected linked primary care, secondary care and microbiology data from patients with culture-confirmed community-onset lower UTI (COLUTI). Antibiotic treatment within ±3 days was considered concordant if the urinary organism was sensitive and discordant if resistant.The primary outcome was the proportion of patients experiencing urinary infection-related hospital admission (UHA) within 30 days. Secondary outcomes were the proportion of patients experiencing reconsultation within 30 days, and the odds of UHA and reconsultation following discordant treatment, adjusting for sex, age, risk factors for complicated UTI, previous antibiotic treatment, recurrent UTI and comorbidities. RESULTS: A total of 11 963 UTI episodes in 8324 patients were included, and 1686 episodes (14.1%, 95% CI 13.5%-14.7%) were discordant. UHA occurred in 212/10 277 concordant episodes (2.1%, 95% CI 1.8%-2.4%) and 88/1686 discordant episodes (5.2%, 95% CI 4.2%-6.4%). Reconsultation occurred in 3961 concordant (38.5%, 95% CI 37.6%-39.5%) and 1472 discordant episodes (87.3%, 95% CI 85.6%-88.8%). Discordant treatment compared with concordant was associated with increased odds of UHA (adjusted OR 2.31, 95% CI 1.77-3.0, P < 0.001) and reconsultation (adjusted OR 11.25, 95% CI 9.66-13.11, P < 0.001) on multivariable analysis. Chronic kidney disease and diabetes mellitus were also independently associated with increased odds of UHA. CONCLUSIONS: One in seven COLUTI episodes in primary care were treated with discordant antibiotics. In higher risk patients requiring urine culture, empirical antibiotic choice optimization could meaningfully reduce adverse outcomes.

Tunable polymeric micelles for taxane and corticosteroid co-delivery.

Nanomedicine holds promise for potentiating drug combination therapies. Increasing (pre)clinical evidence is available exemplifying the value of co-formulating and co-delivering different drugs in modular nanocarriers. Taxanes like paclitaxel (PTX) are widely used anticancer agents, and commonly combined with corticosteroids like dexamethasone (DEX), which besides for suppressing inflammation and infusion reactions, are increasingly explored for modulating the tumor microenvironment towards enhanced nano-chemotherapy delivery and efficacy. We here set out to develop a size- and release rate-tunable polymeric micelle platform for co-delivery of taxanes and corticosteroids. We synthesized amphiphilic mPEG-b-p(HPMAm-Bz) block copolymers of various molecular weights and used them to prepare PTX and DEX single- and double-loaded micelles of different sizes. Both drugs could be efficiently co-encapsulated, and systematic comparison between single- and co-loaded formulations demonstrated comparable physicochemical properties, encapsulation efficiencies, and release profiles. Larger micelles showed slower drug release, and DEX release was always faster than PTX. The versatility of the platform was exemplified by co-encapsulating two additional taxane-corticosteroid combinations, demonstrating that drug hydrophobicity and molecular weight are key properties that strongly contribute to drug retention in micelles. Altogether, our work shows that mPEG-b-p(HPMAm-Bz) polymeric micelles serve as a tunable and versatile nanoparticle platform for controlled co-delivery of taxanes and corticosteroids, thereby paving the way for using these micelles as a modular carrier for multidrug nanomedicine.

Hydroxyapatite fortified mango mousse: Formulation, characterization, and sensory data evaluation using fuzzy logic.

In this experimental study, hydroxyapatite (HAp), as a valuable calcium source, was extracted from discarded goat bone; raw and nano-biogenic powders were prepared through calcination and ultra-sonication. Resultant powders were characterized by using various spectroscopy techniques. As per the findings of atomic absorption spectroscopy, raw and nano-biogenic powders depicted 1439.7 ± 0.12 and 3194.8 ± 0.07 ppm calcium content, respectively. The range of particle size of nano-biogenic and raw powders was 47-139 and 183 nm, respectively. X-ray diffraction (XRD) confirmed crystalline behavior whereas laser-induced breakdown spectroscopy (LIBS)-derived Ca/P-ratio endorsed excellence in nano-biogenic 1.76 against 1.63 in raw powder. In vitro bioavailability of calcium in raw and nano-biogenic powder was ∼36% and ∼39%, respectively. Next, the powders were further used to develop calcium-fortified mango mousse with varied formulations. A maximum overrun of 23.31% was found in the case of "Raw-A," whereas a maximum viscosity of 8489.98 mPa s was found in the case of "Nano-A." Sensory data of mango mousse were obtained by fuzzy logic method, and PCA ranked the Nano-B and Nano-A samples the best in terms of overall acceptability. Meanwhile, the consumer responses toward product likeness and/or dislikeness were recorded by the hedonic scale that endorsed Nano-A and Nano-B formulations as the most preferred samples. PRACTICAL APPLICATION: The revolution in the eating habits of consumers from traditional foods to fast food imposes the development of new products having good nutritional values. Different waste biogenic food sources can provide an acceptable powdered form of ingredients for the development of novel food products. In this regard, the development of novel food products using calcium supplements has gained space in the food industry.

Assessment and verification of chemical inactivation of peste des petits ruminants virus by virus isolation following virus capture using Nanotrap magnetic virus particles.

This study reports development and optimization of a new method for the assessment and verification of the inactivation of peste des petits ruminants virus (PPRV) by chemical agents, including Triton X-100 and commercially available viral lysis buffers. Virus inactivation was confirmed by virus isolation (VI) on Vero cells following capture of the potential residual viruses from treated samples using Nanotrap magnetic virus particles (NMVPs). Since chemical agents are cytotoxic, treated PPRV samples could not be used directly for VI on Vero cell monolayers; instead, they were diluted in Eagle's Minimum Essential Medium (EMEM) to neutralize cytotoxicity and then subjected to virus capture using NMVPs. The NMVPs and the captured viruses were then clarified on a magnetic stand, reconstituted in EMEM, and inoculated onto Vero cells that were examined for cytopathic effect (CPE). No CPE was observed on cells inoculated with treated viruses captured by NMVPs; but CPE was observed on cells inoculated with untreated viruses, including those captured by NMVPs. For further verification, the supernatants of the VI cultures (treated or untreated) were subjected to RNA extraction and PPRV-specific real-time RT-PCR (RT-qPCR). The cycle threshold values were undetectable for the supernatants of VI cultures inoculated with NMVPs reconstituted from treated PPRV but detectable for the supernatants of VI cultures inoculated with untreated PPRV or the NMVPs reconstituted from untreated PPRV, indicating complete inactivation of PPRV. This new method of verification of virus inactivation using NMVPs can be applied to other high impact viruses of agricultural or public health importance. IMPORTANCE Research including diagnosis on highly contagious viruses at the molecular level such as PCR and next-generation sequencing requires complete inactivation of the virus to ensure biosafety and biosecurity so that any accidental release of the virus does not compromise the safety of the susceptible population and the environment. In this work, peste des petits ruminants virus (PPRV) was inactivated with chemical agents, and the virus inactivation was confirmed by virus isolation (VI) using Vero cells. Since the chemical agents are cytotoxic, inactivated virus (PPRV) was diluted 1:100 to neutralize cytotoxicity, and the residual viruses (if any) were captured using Nanotrap magnetic virus particles (NMVPs). The NMVPs and the captured viruses were subjected to VI. No CPE was observed, indicating complete inactivation, and the results were further supported by real-time RT-PCR. This new protocol to verify virus inactivation can be applicable to other viruses.

Optimization, fractional characterization, and antioxidant potential of exopolysaccharides from Levilactobacillus brevis NCCP 963 isolated from "kanji".

A novel exopolysaccharide (EPS) was obtained from Levilactobacillus brevis NCCP 963 isolated from a black carrot drink named "kanji". The culture conditions for maximum EPS yield were explored by the Plackett-Burman (PB) design and response surface methodology (RSM) along with the fractional characterization and antioxidant potential of EPSs. The PB design screened out five significant factors, namely, glucose, sucrose, tryptone, CaCl2, and di-potassium phosphate out of eleven independent factors. The RSM indicated glucose and CaCl2 as significant factors in EPS production and a maximum EPS production of 968.89 mg L-1 was obtained at optimized levels of 10.56% glucose, 9.23% sucrose, 0.75% tryptone, 0.446% CaCl2, and 0.385% K2HPO4. A R2 value above 93% indicates higher variability, depicting the validity of the model. The obtained EPS has a molecular weight of 5.48 × 104 Da and is a homopolysaccharide in nature with glucose monosaccharides. FT-IR analysis showed significant band stretching of C-H, O-H, C-O and C-C and indicated the ß-glucan nature of EPSs. The comprehensive antioxidant investigation showed significant in vitro DPPH, ABTS, hydroxyl, and superoxide scavenging capacity with EC50 values of 1.56, 0.31, 2.1, and 6.7 mg mL-1 respectively. Curd formation from the resulting strain prevented syneresis.

Hospital admission after primary care consultation for community-onset lower urinary tract infection: a cohort study of risks and predictors using linked data.

BACKGROUND: Urinary tract infections (UTIs) are a common indication for antibiotic prescriptions, reductions in which would reduce antimicrobial resistance (AMR). Risk stratification of patients allows reductions to be made safely. AIM: To identify risk factors for hospital admission following UTI, to inform targeted antibiotic stewardship. DESIGN AND SETTING: Retrospective cohort study of East London primary care patients. METHOD: Hospital admission outcomes following primary care consultation for UTI were analysed using linked data from primary care, secondary care, and microbiology, from 1 April 2012 to 31 March 2017. The outcomes analysed were urinary infection-related hospital admission (UHA) and all-cause hospital admission (AHA) within 30 days of UTI in primary care. Odds ratios between specific variables (demographic characteristics, prior antibiotic exposure, and comorbidities) and the outcomes were predicted using generalised estimating equations, and fitted to a final multivariable model including all variables with a P-value <0.1 on univariable analysis. RESULTS: Of the 169 524 episodes of UTI, UHA occurred in 1336 cases (0.8%, 95% confidence interval [CI] = 0.7 to 0.8) and AHA in 6516 cases (3.8%, 95% CI = 3.8 to 3.9). On multivariable analysis, increased odds of UHA were seen in patients aged 55-74 years (adjusted odds ratio [AOR] 1.49) and ≥75 years (AOR 3.24), relative to adults aged 16-34 years. Increased odds of UHA were also associated with chronic kidney disease (CKD; AOR 1.55), urinary catheters (AOR 2.01), prior antibiotics (AOR 1.38 for ≥3 courses), recurrent UTI (AOR 1.33), faecal incontinence (FI; AOR 1.47), and diabetes mellitus (DM; AOR 1.37). CONCLUSION: Urinary infection-related hospital admission after primary care consultation for community-onset lower UTI was rare; however, increased odds for UHA were observed for some patient groups. Efforts to reduce antibiotic prescribing for suspected UTI should focus on patients aged <55 years without risk factors for complicated UTI, recurrent UTI, DM, or FI.

Diverse Repertoire and Relationship of Exopolysaccharide Genes in Cold-Adapted Acinetobacter sp. CUI-P1 Revealed by Comparative Genome Analysis.

This study focused on the exploration of microbial communities inhabiting extreme cold environments, such as the Passu and Pisan glaciers of Pakistan, and their potential utilization in industrial applications. Among the 25 initially screened strains, five were found to be suitable candidates for exopolysaccharide (EPS) production, with strain CUI-P1 displaying the highest yield of 7230.5 mg/L compared to the other four strains. The purified EPS from CUI-P1 was tested for its ability to protect probiotic bacteria and E. coli expressing green fluorescence protein (HriGFP) against extreme cold temperatures, and it exhibited excellent cryoprotectant and emulsification activity, highlighting its potential use in the biotechnological industry. Furthermore, the genome of Acinetobacter sp., CUI-P1 comprised 199 contigs, with a genome size of 10,493,143bp and a G + C content of 42%, and showed 98.197% nucleotide identity to the type genome of Acinetobacter baumannii ATCC 17978. These findings offer promising avenues for the application of EPS as a cryoprotectant, an essential tool in modern biotechnology.

Glomerella fusarioides-catalyzed structural transformation of steroidal drugs mesterolone and methasterone, and anti-inflammatory activity of resulting derivatives.

Transformation of steroidal drug mesterolone (1) with Glomerella fusarioides yielded two new (17α-hydroxy-1α-methyl-5α-androstan-3-one-11α-yl acetate (2) and 15α-hydroxy-1-methyl-5α-androstan-1-en-3,17-dione (3)), and four known derivatives (15α,17ß-dihydroxy-1α-methyl-5α-androstan-3-one (4), 15α-hydroxy-1α-methyl-5α-androstan-3,17-dione (5), 1α-methyl-androsta-4-en-3,17-dione (6) and 15α,17ß-dihydroxy-1-methyl-5α-androstan-1-en-3-one (7). Similarly, G. fusarioides-catalyzed transformation of steroidal drug methasterone (8) afforded four new metabolites, 11α,17ß-dihydroxy-2,17α-dimethylandrosta-1,4-diene-3-one (9), 3a,11α,17ß-trihydroxy-2α,17α-dimethyl-5α-androstane (10), 1ß,3ß,17ß-trihydroxy-2α,17α-dimethyl-5α-androstane (11), and 11α,17ß-dihydroxy-2,17α-dimethylandrosta-1,4-diene-3-one (12). Structures of new derivatives were determined by using 1D-, and 2D-NMR, HREI-MS, and IR spectroscopic data. New derivative 3 was identified as a potent inhibitor of NÈ® production with the IC50 value of 29.9 ± 1.8 µM, in comparison to the standard l-NMMA (IC50 = 128.2 ± 0.8 µM) in vitro. In addition, methasterone (8) (IC50 = 83.6 ± 0.22 µM) also showed a significant activity comparable to new derivative 12 (IC50 = 89.8 ± 1.2 µM). New derivatives 2 (IC50 = 102.7 ± 0.5 µM), 9 (IC50 = 99.6 ± 5.7 µM), 10 (IC50 = 123.5 ± 5.7 µM), and 11 (IC50 = 170.5 ± 5.0 µM) showed a moderate activity. NG-MonomethylL-arginine acetate (IC50 = 128.2 ± 0.8 µM) was used as standared NO⋅- free radicals have an important role in the regulation of immune responses and cellular events. Their overproduction is associated with the pathogenesis of numerous ailments, such as Alzheimer's cardiac disorders, cancer, diabetes, and degenerative diseases. Therefore, inhibition of NÈ® production can help in the treatment of chronic inflammation and associated disorders. All derivatives were found to be non-cytotoxic to human fibroblast (BJ) cell line. The results presented here form the basis of further research for the development of new anti-inflammatory agents with improved efficacy through biotransformation approaches.

Effect of Radical Polymerization Method on Pharmaceutical Properties of Π Electron-Stabilized HPMA-Based Polymeric Micelles.

Polymeric micelles are among the most extensively used drug delivery systems. Key properties of micelles, such as size, size distribution, drug loading, and drug release kinetics, are crucial for proper therapeutic performance. Whether polymers from more controlled polymerization methods produce micelles with more favorable properties remains elusive. To address this question, we synthesized methoxy poly(ethylene glycol)-b-(N-(2-benzoyloxypropyl)methacrylamide) (mPEG-b-p(HPMAm-Bz)) block copolymers of three different comparable molecular weights (∼9, 13, and 20 kDa), via both conventional free radical (FR) and reversible addition-fragmentation chain transfer (RAFT) polymerization. The polymers were subsequently employed to prepare empty and paclitaxel-loaded micelles. While FR polymers had relatively high dispersities (D ∼ 1.5-1.7) compared to their RAFT counterparts (D ∼ 1.1-1.3), they formed micelles with similar pharmaceutical properties (e.g., size, size distribution, critical micelle concentration, cytotoxicity, and drug loading and retention). Our findings suggest that pharmaceutical properties of mPEG-b-p(HPMAm-Bz) micelles do not depend on the synthesis route of their constituent polymers.

Effects of dietary counselling on lipid profile among liposuction patients.

Objectives: To observe the effects of dietary counselling on weight management after liposuction. METHODS: The case-control study was conducted at the La Chirurgie Cosmetic Surgery Centre and Hair Transplant Institute, F-8/3, Islamabad, Pakistan, from January to July 2018, and comprised adults (100) of either gender undergoing liposuction and/or abdominoplasty who were followed for three months in the postoperative period. The subjects were divided into dietary-counselled group A, which received diet plans, and control group B, which followed up without any dietary advice. Lipid profile was done at baseline and three months post-liposuction. Data was analysed using SPSS 20. RESULTS: Of the 100 subjects enrolled, 83(83%) completed the study; 43(51.8%) in group A and 40(48.2%) in group B. Overall, there were 19(22.9%) males, 64(77.1%) females, and 55(66.3%) were aged <40 years, while 28(33.7%) were aged ≥40 years. Intra-group improvement was significant for total cholesterol, low-density lipoprotein, and triglycerides for both the groups (p<0.05). The change for very low-density lipoprotein in group B was not significant (p>0.05). Change in high-density lipoprotein was for the better in group A, while it decreased in group B and the change in both cases was significant (p<0.05). Inter-group differences were not significant (p>0.05) except for total cholesterol (p<0.05). CONCLUSIONS: Liposuction alone resulted in the improvement of lipid profile, while dietary intervention resulted in better values with respect to very low-density lipoprotein and high-density lipoprotein.

Implementation of a quality improvement programme using the Active Patient Link call and recall system to improve timeliness and equity of childhood vaccinations: protocol for a mixed-methods evaluation.

INTRODUCTION: Call and recall systems provide actionable intelligence to improve equity and timeliness of childhood vaccinations, which have been disrupted during the COVID-19 pandemic. We will evaluate the effectiveness, fidelity and sustainability of a data-enabled quality improvement programme delivered in primary care using an Active Patient Link Immunisation (APL-Imms) call and recall system to improve timeliness and equity of uptake in a multiethnic disadvantaged urban population. We will use qualitative methods to evaluate programme delivery, focusing on uptake and use, implementation barriers and service improvements for clinical and non-clinical primary care staff, its fidelity and sustainability. METHODS AND ANALYSIS: This is a mixed-methods observational study in 284 general practices in north east London (NEL). The target population will be preschool-aged children eligible to receive diphtheria, tetanus and pertussis (DTaP) or measles, mumps and rubella (MMR) vaccinations and registered with an NEL general practice. The intervention comprises an in-practice call and recall tool, facilitation and training, and financial incentives. The quantitative evaluation will include interrupted time Series analyses and Slope Index of Inequality. The primary outcomes will be the proportion of children receiving at least one dose of a DTaP-containing or MMR vaccination defined, respectively, as administered between age 6 weeks and 6 months or between 12 and 18 months of age. The qualitative evaluation will involve a 'Think Aloud' method and semistructured interviews of stakeholders to assess impact, fidelity and sustainability of the APL-Imms tool, and fidelity of the implementation by facilitators. ETHICS AND DISSEMINATION: The research team has been granted permission from data controllers in participating practices to use deidentified data for audit purposes. As findings will be specific to the local context, research ethics approval is not required. Results will be disseminated in a peer-reviewed journal and to stakeholders, including parents, health providers and commissioners.

Optimization and cholesterol-lowering activity of exopolysaccharide from Lactiplantibacillus paraplantarum NCCP 962.

Exopolysaccharides (EPSs) are biological polymers with unique structural features have gained particular interest in the fields of food, chemistry and medicine, and food industry. EPS from the food-grade lactic acid bacteria (LAB) can be used as a natural food additives to commercial ones in the processing and development of functional foods and nutraceuticals. The current study was aimed to explore the EPS-producing LAB from the dahi; to optimize the fermentation conditions through Plackett-Burman (PB) and response surface methodology (RSM); and to study its physicochemical, rheological, functional attributes, and cholesterol-lowering activity. Lactiplantibacillus paraplantarum NCCP 962 was isolated among the 08 strains screened at the initial stage. The PB design screened out four independent factors that had a significant positive effect, i.e., lactose, yeast extract, CaCl2, and tryptone, while the remaining seven had a non-significant effect. The RSM exhibited lactose, yeast extract, and CaCl2, significantly contributing to EPS yield. The maximum EPS yield (0.910 g/L) was obtained at 6.57% lactose, 0.047% yeast extract, 0.59% CaCl2, and 1.37% tryptone. The R2 value above 97% explains the higher variability and depicts the model's validity. The resulted EPS was a heteropolysaccharide in nature with mannose, glucose, and galactose monosaccharides. FTIR spectrum reflected the presence of functional groups, i.e., O-H, C-H, C = O, C-O-H, and CH2. SEM revealed a porous and rough morphology of EPS, also found to be thermally stable and negligible weight loss, i.e., 14.0% at 257 °C and 35.4% at 292.9 °C was observed in the 1st and 2nd phases, respectively. Rheological attributes revealed that strain NCCP 962 had high viscosity by increasing the EPS concentration, low pH, and temperature with respectable water holding, oil capacities, foaming abilities, and stability. NCCP 962 EPS possessed up to 46.4% reduction in cholesterol concentration in the supernatant. Conclusively, these results suggested that strain NCCP 962 can be used in food processing applications and other medical fields. KEY POINTS: • The fermentation conditions affect EPS yield from L. paraplantarum and significantly increased yield to 0.910 g/L. • The EPS was heteropolysaccharide in nature and thermally stable with amorphous morphology. • Good cholesterol-lowering potential with the best rheological, emulsifying, and foaming capacities.

Study of metabolic syndrome indicators in newly diagnosed diabetes mellitus type 2 patients in Pakistani population.

BACKGROUND: Metabolic syndrome (MetS) being a biological abnormality confers the highest risk of type 2 diabetes mellitus (T2DM). AIM: To assess MetS indicators in the newly diagnosed T2DM Pakistani population. METHODS: A cross-sectional study (N = 123) with newly diagnosed T2DM patients (gender: both, MeanAge: 49.24 ± 6.84 years) was selected from Medical OPD, Pakistan Institute of Medical Sciences, Islamabad. Basic profile, family history, and physical activity were recorded through a predesigned questionnaire, dietary intake through seven days Food Diary and Food Frequency Questionnaire. Blood pressure and selected clinical signs and symptoms were recorded. Anthropometric measurements included mid-upper arm circumference (MUAC), body mass index (BMI), waist circumference (WC), waist-and-hip ratio (WHR), waist-to-height ratio (WHtR), and conicity index. Lab parameters included fasting blood glucose, HbA1c, insulin levels, and lipid profile. Homeostatic model assessment of insulin resistance (HOMA-IR) was computed to assess insulin resistance. RESULTS: Almost all parameters related to MetS were higher than normal. The prevalence of MetS was 59.7%. BMI, MUAC, and WHtR were independently associated with HOMA-IR, but WC, WHR, and the conicity index had no relationship MetS indicators. CONCLUSION: The prevalence rate of MetS was found to be 59.7% in newly diagnosed T2DM patients. MUAC was found to be a better parameter for the diagnosis of central obesity and insulin resistance in the selected population.

Impact of the COVID-19 pandemic on timeliness and equity of measles, mumps and rubella vaccinations in North East London: a longitudinal study using electronic health records.

OBJECTIVES: To quantify the effect of the COVID-19 pandemic on the timeliness of, and geographical and sociodemographic inequalities in, receipt of first measles, mumps and rubella (MMR) vaccination. DESIGN: Longitudinal study using primary care electronic health records. SETTING: 285 general practices in North East London. PARTICIPANTS: Children born between 23 August 2017 and 22 September 2018 (pre-pandemic cohort) or between 23 March 2019 and 1 May 2020 (pandemic cohort). MAIN OUTCOME MEASURE: Receipt of timely MMR vaccination between 12 and 18 months of age. METHODS: We used logistic regression to estimate the ORs (95% CIs) of receipt of a timely vaccination adjusting for sex, deprivation, ethnic background and Clinical Commissioning Group. We plotted choropleth maps of the proportion receiving timely vaccinations. RESULTS: Timely MMR receipt fell by 4.0% (95% CI: 3.4% to 4.6%) from 79.2% (78.8% to 79.6%) to 75.2% (74.7% to 75.7%) in the pre-pandemic (n=33 226; 51.3% boys) and pandemic (n=32 446; 51.4%) cohorts, respectively. After adjustment, timely vaccination was less likely in the pandemic cohort (0.79; 0.76 to 0.82), children from black (0.70; 0.65 to 0.76), mixed/other (0.77; 0.72 to 0.82) or with missing (0.77; 0.74 to 0.81) ethnic background, and more likely in girls (1.07; 1.03 to 1.11) and those from South Asian backgrounds (1.39; 1.30 to 1.48). Children living in the least deprived areas were more likely to receive a timely MMR (2.09; 1.78 to 2.46) but there was no interaction between cohorts and deprivation (Wald statistic: 3.44; p=0.49). The proportion of neighbourhoods where less than 60% of children received timely vaccination increased from 7.5% to 12.7% during the pandemic. CONCLUSIONS: The COVID-19 pandemic was associated with a significant fall in timely MMR receipt and increased geographical clustering of measles susceptibility in an area of historically low and inequitable MMR coverage. Immediate action is needed to avert measles outbreaks and support primary care to deliver timely and equitable vaccinations.

Nanomedicine for Treating Muscle Dystrophies: Opportunities, Challenges, and Future Perspectives.

Muscular dystrophies are a group of genetic muscular diseases characterized by impaired muscle regeneration, which leads to pathological inflammation that drives muscle wasting and eventually results in weakness, functional dependency, and premature death. The most known causes of death include respiratory muscle failure due to diaphragm muscle decay. There is no definitive treatment for muscular dystrophies, and conventional therapies aim to ameliorate muscle wasting by promoting physiological muscle regeneration and growth. However, their effects on muscle function remain limited, illustrating the requirement for major advancements in novel approaches to treatments, such as nanomedicine. Nanomedicine is a rapidly evolving field that seeks to optimize drug delivery to target tissues by merging pharmaceutical and biomedical sciences. However, the therapeutic potential of nanomedicine in muscular dystrophies is poorly understood. This review highlights recent work in the application of nanomedicine in treating muscular dystrophies. First, we discuss the history and applications of nanomedicine from a broader perspective. Second, we address the use of nanoparticles for drug delivery, gene regulation, and editing to target Duchenne muscular dystrophy and myotonic dystrophy. Next, we highlight the potential hindrances and limitations of using nanomedicine in the context of cell culture and animal models. Finally, the future perspectives for using nanomedicine in clinics are summarized with relevance to muscular dystrophies.

Determinants of resistant starch accumulation in wheat endosperm.

A part of the big three cereal crops in the world, wheat has become a major constituent of the everyday food chain and is grown at a massive scale to meet global demands. This makes it an important crop from an economic as well as food security perspective. Selection of high-quality cultivars and consistent trait enhancement for such cultivars is crucial, and in light of new challenges from climate change, this has become an absolute necessity of time. In this regard, we conducted a detailed qualitative and quantitative trait analysis for multiple commercially viable varieties of wheat, and corresponding results were subjected to a series of critical statistical analyses. Final results have shown that five cultivars including Uqaab-2000, Faisalabad- 85, Anmol-19, NARC-2009, and Pirsabak-2004 depicts higher levels of various essential qualitative and quantitative traits (including Starch content, grain weight, RS content, Protein content, etc.) and are most viable varieties for further growth and trait enhancements to meet regional and global food challenges.

Evolutionary Dynamics of Foot and Mouth Disease Virus Serotype A and Its Endemic Sub-Lineage A/ASIA/Iran-05/SIS-13 in Pakistan.

Foot and mouth disease (FMD) causes severe economic losses to the livestock industry of endemic countries, including Pakistan. Pakistan is part of the endemic pool 3 for foot and mouth disease viruses (FMDV), characterized by co-circulating O, A, and Asia 1 serotypes, as designated by the world reference laboratory for FMD (WRL-FMD). FMDV serotype A lineage ASIA/Iran-05 is widespread in buffalos and cattle populations and was first reported in Pakistan in 2006. This lineage has a high turnover, with as many as 10 sub-lineages reported from Pakistan over the years. In this study, we reconstructed the evolutionary, demographic, and spatial history of serotype A and one of its sub-lineages, A/ASIA/Iran-05/SIS-13, prevalent in Pakistan. We sequenced nearly complete genomes of three isolates belonging to sub-lineage A/ASIA/Iran-05/SIS-13. We estimated recombination patterns and natural selection acting on the serotype A genomes. Source and transmission routes in Pakistan were inferred, and the clustering pattern of isolates of the SIS-13 sub-lineage were mapped on a tree. We hereby report nearly complete genome sequences of isolates belonging to sub-lineage A/ASIA/Iran-05/SIS-13, along with purported recombinant genomes, and highlight that complete coding sequences can better elucidate the endemic history and evolutionary pressures acting on long-term co-circulating FMDV strains.
