Utilization of low-grade walnut kernels for oil extraction using eco-friendly methods: a comparative analysis of oil composition, antioxidant and antimicrobial activity.

Walnut oil was extracted using three different eco-friendly extraction methods, solvent extraction (using ethyl acetate [EA] and ethanol [ET]), aqueous enzymatic extraction (AEE), and ultrasound-assisted enzymatic extraction (UAEE), and their lipid yield, lipid composition, physicochemical analysis, mineral composition, total phenols, antioxidant capacity, and antimicrobial activity were analyzed and compared. The AEE technique offered a greater yield (50.6%) than the other extraction methods and gave comparatively higher linoleic acid (66.12%) content. Palmitic, oleic, linoleic, linolenic, and stearic acids were the principal components that GC/MS detected in all the oil samples. UAEE produced the most polyphenols (0.49 mgGAE/g), followed by AEE (0.46 mgGAE/g), EA (0.45 mgGAE/g), and ET (0.35 mgGAE/g). The DPPH assay results were in the order of UAEE (191 µmolTE/kg) > AEE (186 µmolTE/kg) > EA (153 µmolTE/kg) > ET (130 µmolTE/kg). The FRAP assay findings showed a similar pattern: UAEE (112 molTE/kg) > AEE (102 molTE/kg) > EA (96 molTE/kg) > ET (82 molTE/kg). Results suggested that for a higher extraction yield, AEE is the better technique and UAEE is the recommended method for enhancing walnut oil antioxidant capacity. Additionally, it was found that polyphenols considerably increased the antioxidant capacity of walnut oil and are thought to be health-promoting. The results demonstrated the antibacterial effectiveness of the extracted oil against Bacillus subtilis, Bacillus licheniformis, and Staphylococcus aureus. This study provides information about low-cost and ecofriendly technologies of walnut oil extraction for food, cosmetic, and medical uses.

Advances in apple packaging: a review.

Apple (Malus domestica) belongs to the family Rosaceae. It is one of the most commonly cultivated fruit in all temperate zones of the world and holds an equally important place in the global economy. Apple is a climacteric fruit and undergoes metabolic changes even after the harvest and thus prone to post-harvest losses. The packaging of apples plays an important role in extending the shelf life of the apples and also maintains the quality during distribution and transport. The prime role of packaging is to contain the food commodity and protect the enclosed product from external damage. But other functions such as traceability, convenience and temper evidence are of secondary importance. Different packaging techniques are employed for the packaging of apples which include both conventional (wooden boxes, corrugated fiber boxes, crates) and non-conventional packaging like modified atmosphere packaging (MAP), active packaging, edible coatings, etc.

Cytokine-induced GAPDH sulfhydration affects PSD95 degradation and memory.

Induction of a proinflammatory cytokine, interleukin-1ß (IL-1ß) plays a role in memory impairment associated with various neurological disorders and brain injury. Here we show that IL-1ß-induced memory impairment in brain is mediated by hydrogen sulfide (H2S) synthesized by cystathionine beta-synthase (CBS). H2S modifies GAPDH essentially via sulfhydration in dendrites, which promotes its binding to the E3 ligase protein, Siah. Then Siah binds to a critical synaptic scaffolding molecule, PSD95, and leads it to degradation via ubiquitination. In CBS heterozygous mice (cbs(+/-)) and primary neurons depleted with either CBS or IL-1R, IL-1ß-induced loss of PSD95 was rescued along with a decrease in the level of GAPDH sulfhydration. Moreover, decrease in the loss of PSD95 in cbs(+/-) mice results in improvement of IL-1ß-induced cognitive deficits and neurobehavioral outcomes. Thus, our findings reveal a mechanism where GAPDH sulfhydration appears to be a physiologic determinant of cytokine-induced memory impairment in brain.

RIT1 GTPase Regulates Sox2 Transcriptional Activity and Hippocampal Neurogenesis.

Adult neurogenesis, the process of generating mature neurons from neuronal progenitor cells, makes critical contributions to neural circuitry and brain function in both healthy and disease states. Neurogenesis is a highly regulated process in which diverse environmental and physiological stimuli are relayed to resident neural stem cell populations to control the transcription of genes involved in self-renewal and differentiation. Understanding the molecular mechanisms governing neurogenesis is necessary for the development of translational strategies to harness this process for neuronal repair. Here we report that the Ras-related GTPase RIT1 serves to control the sequential proliferation and differentiation of adult hippocampal neural progenitor cells, with in vivo expression of active RIT1 driving robust adult neurogenesis. Gene expression profiling analysis demonstrates increased expression of a specific set of transcription factors known to govern adult neurogenesis in response to active RIT1 expression in the hippocampus, including sex-determining region Y-related HMG box 2 (Sox2), a well established regulator of stem cell self-renewal and neurogenesis. In adult hippocampal neuronal precursor cells, RIT1 controls an Akt-dependent signaling cascade, resulting in the stabilization and transcriptional activation of phosphorylated Sox2. This study supports a role for RIT1 in relaying niche-derived signals to neural/stem progenitor cells to control transcription of genes involved in self-renewal and differentiation.

Processing and storage of apricots: effect on physicochemical and antioxidant properties.

The present study was carried out to evaluate the effect of processing methods and storage periods on the three apricot varieties viz. CITH-1, CITH-2 and New Castle. Apricots were processed by freezing and canning of pulp and drying of whole apricots. After processing these were analysed for various physicochemical and antioxidant properties for a storage period of 12 months at 4 month interval. The results for physicochemical properties like moisture content, TSS, total sugars and reducing sugars showed significant variation with respect to varieties and processing methods during storage. Apricots processed by canning showed highest retention of antioxidants in terms of TPC, FRAP, DPPH and metal chelating activity throughout storage period than that of frozen and dried one. CITH-2 processed by canning, freezing and drying method showed highest antioxidant properties than CITH-1 and New Castle. It can be concluded from the study that canning and freezing can preserve the apricot pulp for 12 months and significantly retain bioactive compounds.

Designing a model of hospital information system acceptance: Organizational culture approach.

Background: The significance and influence of organizational culture on Information Technology acceptance, especially in healthcare field, has been recognized as a source of organizational inertia. This study aimed at developing a model of Hospital Information System (HIS) acceptance for non-teaching hospitals of Iran University of Medical Sciences to encourage the authorities to promote organizational culture and successful application of HIS. Methods: The proposed model was developed according to Michigan Organizational Assessment Questionnaire (MOAQ), Harrison, Hofstede models, and Comparative Values Framework (CVF). The questionnaires were designed based on the model and distributed among 400 HIS users in the hospitals under study, who were selected using stratified random sampling. The structural equation modeling method was used for data analysis in LISREL software. Results: According to the final model, the influences of developmental culture on perceived usefulness, the relationship of 4 types of organizational culture with mandatoriness according to CVF, and the relationships of hierarchical and developmental culture with system use were attested. The relationships between supervision and 4 variables of HIS acceptance were confirmed. Furthermore, the influence of process/ result oriented culture on user satisfaction was demonstrated. The normed chi square index (2.60) revealed that the final model was fitted to the data. The indices were as follow: GFI= 0.95, CFI= 0.97, AGFI= 0.88, RMSEA= 0.064. Conclusion: The components and structural relationships in the model of this study are applicable in the related hospitals, and using this model can promote organizational culture and acceptance of HIS by the users.

Accumulation of reactivity to MBP sensitizes TRAIL mediated oligodendrocyte apoptosis in adult sub cortical white matter in a model for human multiple sclerosis.

Reactivity to myelin associated proteins is the hallmark of human multiple sclerosis (M.S) and its experimental counterparts. However, the nature of such reactivity has not been described fully. Herein, we report that myelin basic protein (MBP) reactivity accumulates in a rat model for M.S. over a period of time and sensitizes TRAIL mediated progressive oligodendrocyte apoptosis. We used active immunization by Myelin Oligodendrocyte Glycoprotein (MOG, 50 µg) to study chronic remitting relapsing encephalomyelitis in rats. A time point analysis of the progressive disease revealed cumulative accumulation of anti myelin basic protein antibodies during the disease progression with minimal change in the anti-MOG antibodies. Increased reactivity to MBP was studied to sensitize TNF related apoptosis-inducing ligand (TRAIL) and other proinflammatory cytokines in a cumulative fashion leading to the Caspase dependent apoptosis of oligodendrocytes and myelin loss. In a rescue experiment, we could limit the demyelination and prevent disease progression by neutralizing the effector, TRAIL in an early stage of the disease. This is the first study to identify the accumulation of MBP antibodies in MOG induced EAE which possibly leads to TRAIL sensitized oligodendrocyte apoptosis in the white mater of EAE rats. This finding stresses on the need to study MBP antibody titers in M.S. patients and therefore might serve as an alternate marker for progressive demyelination.

Foxo3a transcriptionally upregulates AQP4 and induces cerebral edema following traumatic brain injury.

Increased cranial pressure due to development of edema contributes significantly to the pathology of traumatic brain injury (TBI). Induction of an astrocytic water channel protein, Aquaporin 4 (AQP4), is known to predominantly contribute to cytotoxic edema following TBI. However, the mechanism for the increase in AQP4 following 24 h of TBI is poorly understood. Here we show that transcriptional activation of a ubiquitously expressed mammalian forkhead transcription factor, Foxo3a, induces cerebral edema by increasing the AQP4 level in the controlled cortical impact model of TBI in mice. TBI stimulates nuclear translocation of Foxo3a in astrocytes and subsequently augments its binding to AQP4 promoter in pericontusional cortex. Nuclear accumulation of Foxo3a is augmented by a decrease in phosphorylation at its Ser256 residue due to inactivation of Akt after TBI. Depletion of Foxo3a in mice rescues cytotoxic edema by preventing induction of AQP4 as well as attenuates memory impairment after TBI in mice.

Valorisation of apple pomace for the development of high-fibre and polyphenol-rich wheat flour cookies.

Apple pomace, abundant in dietary fibre and polyphenols, often goes unutilized, contributing to environmental pollution as it is discarded in open fields of Jammu and Kashmir. This study aimed to develop functional cookies fortified with apple pomace powder (APP), an industrial by-product. Wheat flour-APP formulations (0%, 5%, 10%, and 15%) were assessed. APP addition notably affected color values and functional properties, enhancing water and oil absorption capacities, swelling power, foam capacity and stability. Phenolic content increased significantly (p < 0.05) post-fortification, elevating antioxidant properties. FT-IR spectroscopy identified distinctive chemical components in wheat flour and APP. Sensory evaluation favored cookies with 10% APP, indicating their potential for consumer acceptance. Thus, APP shows promise for producing innovative functional cookies, improving consumer health, utilizing industrial by-products, and reducing waste from apple processing plants, thereby mitigating environmental pollution.

Defense strategies and associated phytohormonal regulation in Brassica plants in response to chewing and sap-sucking insects.

Plants have evolved distinct defense strategies in response to a diverse range of chewing and sucking insect herbivory. While chewing insect herbivores, exemplified by caterpillars and beetles, cause visible tissue damage and induce jasmonic acid (JA)-mediated defense responses, sucking insects, such as aphids and whiteflies, delicately tap into the phloem sap and elicit salicylic acid (SA)-mediated defense responses. This review aims to highlight the specificity of defense strategies in Brassica plants and associated underlying molecular mechanisms when challenged by herbivorous insects from different feeding guilds (i.e., chewing and sucking insects). To establish such an understanding in Brassica plants, the typical defense responses were categorized into physical, chemical, and metabolic adjustments. Further, the impact of contrasting feeding patterns on Brassica is discussed in context to unique biochemical and molecular modus operandi that governs the resistance against chewing and sucking insect pests. Grasping these interactions is crucial to developing innovative and targeted pest management approaches to ensure ecosystem sustainability and Brassica productivity.

Germ Cell Tumors in 46, XY Gonadal Dysgenesis.

Introduction: To present the clinical data, investigative profile, management, and follow-up of patients with 46, XY gonadal dysgenesis with germ cell tumors from the endocrine unit of a tertiary care university hospital. Materials and Methods: This retrospective study included 3 cases of 46, XY gonadal dysgenesis with germ cell tumors evaluated and managed at the Department of Endocrinology, Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir, over a period of 13 years from (September 2008 to December 2021). Results: Over a period of 13 years, we diagnosed and managed 7 patients with 46, XY gonadal dysgenesis. This included 4 patients with pure gonadal dysgenesis (PGD; Swyer syndrome), 2 patients with mixed gonadal dysgenesis (MGD), and one patient with partial gonadal dysgenesis. Out of these 7 patients, three patients developed germ cell tumors, one patient with MGD, and two patients with pure PGD (Swyer syndrome). In all three patients, germ cell tumor was the first presentation of DSD. The patient with MGD presented with primary amenorrhea and virilization, while the two patients with PGD presented as phenotypic females with primary amenorrhea and pelvic mass. All three patients developed seminomatous cancers. Patient with MGD developed seminoma and the two patients with PGD (Swyer syndrome) developed dysgerminoma. The patients were managed with bilateral gonadectomy with removal of the tumor. In addition, the 2 patients with PGD (Swyer syndrome) received combined chemotherapy. On a follow up ranging from 1 to 10 years, all three patients are disease free. Conclusions: we conclude that germ cell tumors may be the first presentation of 46, XY gonadal dysgenesis. In all phenotypic females with primary amenorrhea and dysgerminoma, karyotype is a must to uncover the diagnosis of PGD. In addition virilization may be clue to the presence of germ cell tumor in a patient with 46, XY gonadal dysgenesis.

Profiling blood-based brain biomarkers and cytokines in experimental autoimmune encephalomyelitis model of multiple sclerosis using single-molecule array technology.

Experimental autoimmune encephalomyelitis (EAE) remains a widely used pre-clinical animal model to study multiple sclerosis (MS). Blood-based cytokines and CNS biomarkers are increasingly used as predictors of neurodegeneration, disease activity, and disability in MS. However, there exists variation in animal model characterization and disease course across animal strains/studies due to understudied confounding factors, limiting the utility of these biomarkers to predict disease activity in EAE. In this study, we investigated the profile of blood-based analytes including, cytokines (IL6, IL17, IL12p70, IL10, and TNFα) and neural markers (NFL and GFAP) in the plasma of relapsing-remitting (RR) (SJL) and chronic (B6) models of EAE during different phases (acute, chronic, and progressive) of disease course using ultrasensitive single molecule array technology (SIMoA, Quanterix), which can detect ultra-low levels of a wide range of analytes. NFL showed a substantial increase during post-disease onset at peak, chronic, and progressive phases in both RR SJL and chronic B6 models of EAE. The increase was markedly pronounced in the chronic B6 model. The leakage of GFAP from CNS into the periphery was also higher after disease onset in EAE, however, it was highest during the acute phase in B6. Out of all cytokines, only IL10 showed consistently lower levels in both models of EAE along the disease duration. We report that NFL, GFAP, and IL10 may be more useful predictors of disease activity and neurological outcome in EAE, which would make them potential candidates for use as surrogate markers for preclinical testing of therapeutic interventions in MS.

Diversity and characterization of antagonistic bacteria against Pseudomonas syringae pv. actinidiae isolated from kiwifruit rhizosphere.

Kiwifruit bacterial canker caused by Pseudomonas syringae pv. actinidiae (Psa) is a severe global disease. However, effective biological control agents for controlling Psa are currently unavailable. This study aimed to screen potential biological control agents against Psa from the kiwifruit rhizosphere. In this study, a total of 722 isolates of bacteria were isolated from the rhizosphere of kiwifruit orchards in five regions of China. A total of 82 strains of rhizosphere bacteria showed antagonistic effects against Psa on plates. Based on amplified ribosomal DNA restriction analysis (ARDRA), these antagonistic rhizosphere bacteria were grouped into 17 clusters. BLAST analyses based on 16S rRNA gene sequence revealed 95.44%-100% sequence identity to recognized species. The isolated strains belonged to genus Acinetobacter, Bacillus, Chryseobacterium, Flavobacterium, Glutamicibacter, Lysinibacillus, Lysobacter, Pseudomonas, Pseudarthrobacter, and Streptomyces, respectively. A total of four representative strains were selected to determine their extracellular metabolites and cell-free supernatant activity against Psa in vitro. They all produce protease and none of them produce glucanase. One strain of Pseudomonas sp. produces siderophore. Strains of Bacillus spp. and Flavobacteria sp. produce cellulase, and Flavobacteria sp. also produce chitinase. Our results suggested that the kiwifruit rhizosphere soils contain a variety of antagonistic bacteria that effectively inhibit the growth of Psa.

Assessing indigenous community's perspectives and attitudes toward tourism development impacts in the northwestern Himalayas, India.

An assessment and monitoring of tourism impacts coupled with community perception have emerged as a vital tool for ensuring the sustainability of mountain tourism destinations in recent years. The present study aims to explore the indigenous community's perspectives on tourism impacts and their participation in the process of tourism development at Doodhpathri, an emerging tourist resort in Jammu and Kashmir, India. A non-probability convenience sampling method based on 344 questionnaires has been used to accomplish the research objectives. Inferential statistics and factor analysis were employed to analyze the collected data. Our assessment reveals that in general, tourism is viewed as a development industry. Its positives are better perceived than its negatives, given that it generates employment prospects, boosts household income, improves the image of the area, and raises the indigenous community's standard of living. However, a substantial portion of the population living in the area perceives tourism activities as the cause of multiple environmental and biophysical issues, such as increased waste generation leading to pollution and water quality deterioration. On the whole, most of the residents were positive about future tourism development and optimistic about tourism management practices. However, the area has recently observed a voluminous influx of both local and foreign tourists, which necessitates the formulation of a sustainable tourism planning strategy.

Probiotic-fortified fruit juices: Health benefits, challenges, and future perspective.

Consumers' growing interest in using foods that improve health has motivated researchers and the food industry to develop new functional products, such as foods containing probiotics or live microbes. Probiotics have functional attributes that could satisfy most basic nutritional and therapeutic supplementation requirements. These microbes positively respond to clinical therapies against diseases and illnesses such as rotavirus-associated diarrhea, irritable bowel syndrome, and food allergies. Moreover, the role of probiotics in the prevention and treatment of obesity, diabetes, cancer, and diseases related to pathogenic microbes is an exciting and rapidly advancing research arena. Probiotic supplementation usually involves dairy products. However, because of the growing number of individuals affected by lactose intolerance and/or vegans, other food matrices like fruits, vegetables, cereals, and so on, have been studied as potential carriers for these microorganisms, presenting an alternative and better source in the process of assessing novel probiotic strains. The present review discusses the various factors affecting the survival of probiotics during storage in fruit juices, the possible effect of probiotics on sensory attributes and the overall acceptance of the products, and future technologies to improve the viability of probiotics.

Gender Disparities in Prolactinomas: Unravelling Clinical Patterns, Metabolic Variations, and Treatment Responses.

Background and objective Individuals with prolactinoma exhibit elevated rates of obesity, metabolic syndrome (MS), and dyslipidemia compared to their healthy counterparts. However, there is a lack of data regarding metabolic variance between male and female prolactinoma patients. Consequently, this study aimed to investigate and compare sex-specific discrepancies in metabolic abnormalities among individuals diagnosed with prolactinoma. Methods In this prospective study, 80 treatment-naïve patients with prolactinoma (12 males and 68 females) underwent clinical assessments and laboratory investigations. The measured parameters included blood glucose, total cholesterol (TC), triglycerides (TG), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), urea, creatinine, uric acid, and blood glucose levels. The patients were treated with cabergoline, a dopamine agonist, and reevaluated after 12 weeks. Results Forty-eight patients had microprolactinomas (all females), and 32 had macroprolactinomas (20 females, 12 males). The mean age was 28.30±7.49 years for females and 28.91±7.12 years for males (p=0.71). The median symptom duration was 12 months (range 1-72 months, IQR 4-16 months), with no significant difference between males (median 12 months, IQR 5-54 months) and females (median 12 months, IQR 10-24 months, p=0.620). The median serum prolactin (PRL) was 988 ng/mL (IQR 471-1,439) in males and 165 ng/mL (IQR 90-425) in females (p<0.05). Males showed higher HbA1c, BGF, TC, TG, LDL-C, and higher rates of obesity, MS, and diabetes mellitus. Treatment with cabergoline resulted in significant improvements in the HbA1c, BGF, TC, TG, and LDL-C levels. Conclusion Males with prolactinomas had larger tumor sizes and higher serum PRL levels than females. Additionally, males exhibited worse metabolic parameters than females. However, there was no significant difference in the duration of symptoms or age at diagnosis between the two groups.

Pro-resolution lipid mediator maresin-1 ameliorates inflammation, promotes neuroprotection, and prevents disease progression in experimental models of multiple sclerosis.

Multiple sclerosis (MS) is the most common inflammatory neurodegenerative disease in young adults, resulting in neurological defects and disability. The endogenous mechanisms to resolve inflammation are intact but become defective in patients, resulting in lack of resolution mediators and unresolved chronic inflammation. Docosahexaenoic acid (DHA) metabolism being impaired in MS, we hypothesize that supplementing its downstream metabolite maresin 1 (MaR1) will alleviate inflammation and demyelination in preclinical mouse model of MS; experimental allergic encephalomyelitis (EAE). Restoration of MaR1 by its exogenous administration in EAE mice propagated inflammatory resolution and had a protective effect on neurological deficits, prevented disease progression, and reduced disease severity by reducing immune cell infiltration (CD4+IL17+ and CD4+IFN-γ+) into the CNS. It significantly reduced the proinflammatory cytokine IL17 and promoted an anti-inflammatory response via IL10 and IL4. Neutralization of IL10 abolished the protective effect of MaR1 in EAE confirming IL10 is mediating MaR1 effect in EAE. Furthermore, it improved the pathophysiology and exerted neuroprotective effects by mitigating disease signs in EAE as evidenced by lower levels of NFL in the plasma of treated group compared to control and higher MBP expression in the brain from the MaR1 treated mice, decreased inflammatory infiltrates, and less demyelination and vacuolization in the spinal cord tissue sections of treated mice. SCENITH data confirmed that MaR1 maintains myelin by regulating oligodendrocyte metabolism. Also, it induces metabolic reprogramming in infiltrating CD4 cells and macrophages, which modulate their phenotype. Metabolic changes induced macrophages by MaR1 restores the impaired efferocytosis in EAE, promoting clearance of damaged myelin and dead cells; thereby lowering the disability with disease course. Overall, MaR1 supplementation has anti-inflammatory and neuroprotective effects in preclinical animal models and induces metabolic reprogramming in disease associated cell-types, promotes efferocytosis, implying that it could be a new therapeutic molecule in MS and other autoimmune diseases. Highlights: Inflammation is dysregulated in EAE due to impaired synthesis of DHA derived proresolving lipid mediator MaR1.Administration of the resolution agonist MaR1 propagates resolution processes and improves neurological outcome in RR model of EAE.MaR1 ameliorates clinical signs of EAE by attenuating pro-inflammatory cytokine IL17 mediated response and promoting anti-inflammatory response through IL10.MaR1 supplementation improves the pathophysiology in EAE and shows neuroprotection as indicated by the lower levels of NFL in the plasma and higher expression of MBP in the brain of treated mice.MaR1 induces metabolic reprogramming in disease-associated cell types.MaR1 promotes efferocytosis in EAE through metabolic reprogramming of macrophages. Significance: Inflammatory process is a protective response to several challenges like injury or infection. However, it must resolve over time to maintain tissue homeostasis. Impaired or delayed resolution leads to damaging effects, including chronic inflammation, tissue damage, and disease progression as occurs in multiple sclerosis (MS). We report that inflammation is dysregulated in preclinical animal model of MS, experimental autoimmune encephalomyelitis (EAE), partially due to impaired synthesis of proresolving lipid mediators. We show that the administration of the resolution agonist known as maresin 1 (MaR1) in EAE actively propagates resolution processes and improves neurological outcome. We conclude that MaR1 is a potential interventional candidate to attenuate dysregulated inflammation and to restore neurological deficits in EAE.

Immuno-Responsive Gene-1: A mitochondrial gene regulates pathogenic Th17 in CNS autoimmunity mouse model.

Pathogenic Th17 cells are crucial to CNS autoimmune diseases like multiple sclerosis (MS), though their control by endogenous mechanisms is unknown. RNAseq analysis of brain glial cells identified immuno-responsive gene 1 (Irg1), a mitochondrial-related enzyme-coding gene, as one of the highly upregulated gene under inflammatory conditions which were further validated in the spinal cord of animals with experimental autoimmune encephalomyelitis (EAE), an animal model of MS. Moreover, Irg1 mRNA and protein levels in myeloid, CD4, and B cells were higher in the EAE group, raising questions about its function in CNS autoimmunity. We observed that Irg1 knockout (KO) mice exhibited severe EAE disease and greater mononuclear cell infiltration, including triple-positive CD4 cells expressing IL17a, GM-CSF, and IFNγ. Lack of Irg1 in macrophages led to higher levels of Class II expression and polarized myelin primed CD4 cells into pathogenic Th17 cells through the NLRP3/IL1ß axis. Our findings show that Irg1 in macrophages plays an important role in the formation of pathogenic Th17 cells, emphasizing its potential as a therapy for autoimmune diseases, including MS.

Role of probiotics and prebiotics in mitigation of different diseases.

Probiotics and their food sources, prebiotics, are known to have qualities that help with gastrointestinal issues along with overall improvement in health and well-being. Pro- and prebiotics play a key role in neuroimmune processes. Their beneficial effects on health are linked to interactions of the gastrointestinal tract, immune system, and neurologic systems. The interaction between the microflora-gut-brain axis has a profound effect on brain function, thereby influencing the overall well-being of an individual. Nutritionists, researchers, regulatory bodies (World Health Organization/Food and Agriculture Organization), pharmaceutical, and food manufacturers are currently engaged in enhancing the potential of nutrition in health maintenance and disease prevention. Nutrition has the potential to increase psychological well-being and could be used much as are psychiatric drugs. Probiotics and prebiotics have evolved as promising therapeutic techniques to treat several disease conditions associated with the gastrointestinal tract. The aim of this review was to provide useful information about the use of probiotics and prebiotics in mitigation of various diseases such as COVID-19, congenital heart disease, diarrhea, inflammatory bowel disease, hypertension, genitourinary tract infection, colon cancer, immune system defense, mineral absorption, allergic disorders, and atopic dermatitis.

Influence of Canning and Storage on Physicochemical Properties, Antioxidant Properties, and Bioactive Compounds of Apricot (Prunus armeniaca L.) Wholes, Halves, and Pulp.

This study aimed to examine the effect of canning and storage on physicochemical, mineral, and antioxidant properties and phenolic composition of apricot wholes, halves, and pulp. The findings for physicochemical properties revealed that the total soluble solids, titratable acidity, total sugars, and ascorbic acid were found higher in apricot pulp (37.15, 1.39, and 20.74% and 7.21 mg/100 g FW, respectively) followed by apricot wholes and halves throughout the storage period. The remarkable contents of potassium, phosphorous, zinc, copper, iron, and manganese were found in the apricot pulp which revealed that canning and storage slightly affected the mineral composition. Bioactive substances were identified and quantified by reversed-phase high-performance liquid chromatography, which indicated a higher presence of chlorogenic acid (34.45 mg/kg FW), quercitin-3-glucoside (16.78 mg/kg FW), neochlorogenic acid (26.52 mg/kg FW), gallic acid (5.37 mg/kg FW), kaempferol (14.22 mg/kg FW), ellagic acid (6.02 mg/kg FW), procyanidin B2 (8.80 mg/kg FW), and epicatechin (9.87 mg/kg FW) in apricot pulp followed by apricot wholes and halves throughout the storage period. The total phenolic content was found highest in apricot pulp (13.76 GAE mg/100 g FW) followed by wholes (8.09 GAE mg/100 g FW) and halves (6.48 GAE mg/100 g FW) which decreased significantly throughout the storage period. Antioxidant properties were assessed by DPPH, ABTS+, MCA, and BCBA, which were found higher in the apricot pulp (92.23 TEAC µg/g DW, 92.33 TEAC µg/g DW, 33.80 TEAC µg/g DW, and 68.40 TEAC µg/g DW, respectively) that is correlated with the higher presence of bioactive compounds. Thus, apricot pulp containing excellent sources of nutrients, minerals, phytochemicals, and antioxidant components could be used for consumption purposes that provide nutraceuticals and antioxidants globally.
