Comparison of gut microbiota profiles between patients suffering from elderly frailty syndrome and non-frail elderly individuals.

BACKGROUND: Frailty syndrome is a state of increased vulnerability to stressors, marked by lowered physical strength and increased dependence on others. The well-established changes in gut microbiota associated with old age suggest a probable relationship between gut microbiota and frailty. METHODS AND RESULTS: This study was aimed at finding the relationship between gut microbiota and frailty syndrome, by comparing the sociodemographic data and the gut microbiota profiles of 23 non-frail and 14 frail elderly individuals. We used the quantitative polymerase chain reaction method (qPCR) to determine the bacterial loads of Bifidobacteria, Lactobacillus, Bacteroidetes, Prevotella, and Escherichia coli in stool samples from test subjects. We discovered a significant increase in the bacterial load of Prevotella in frail elderly individuals aged 70 or above. Other bacterial loads and ratios were not significantly different between the two groups. CONCLUSIONS: More comprehensive studies with larger sample sizes and encompassing a wider range of inflammation-related bacteria need to be performed to discover the existence and exact nature of these relations.

B lymphocytes in COVID-19: a tale of harmony and discordance.

B lymphocytes play a vital role in the human defense against viral infections by producing specific antibodies. They are also critical for the prevention of infectious diseases by vaccination, and their activation influences the efficacy of the vaccination. Since the beginning of coronavirus disease 2019 (COVID-19), which became the main concern of the world health system, many efforts have been made to treat and prevent the disease. However, for the development of successful therapeutics and vaccines, it is necessary to understand the interplay between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19, and the immune system. The innate immune system provides primary and nonspecific defense against the virus, but within several days after infection, a virus-specific immune response is provided first by antibody-producing B cells, which are converted after the resolution of disease to memory B cells, which provide long-term immunity. Although a failure in B cell activation or B cell dysfunction can cause a severe form of the disease and also lead to vaccination inefficiency, some individuals with B cell immunodeficiency have shown less production of the cytokine IL-6, resulting in a better disease outcome. In this review, we present the latest findings on the interaction between SARS-CoV-2 and B lymphocytes during COVID-19 infection.

Investigation of the Relationship between Aspirin-Sensitivity and Poor Response to Medical Management in NSAIDs-exacerbated Respiratory Disease Patients with Sinonasal Polyposis.

Background: NSAID-exacerbated respiratory disease (N-ERD) is a highly heterogeneous disorder with various clinical symptoms. The aspirin challenge test is a gold standard method for its diagnosis, and there are still no reliable in vitro diagnostic biomarkers yet. Oral challenge tests are time-consuming and may be associated with a risk of severe systemic reactions. This study aimed to evaluate whether patients with poor responses to medical management are more susceptible to being aspirin-sensitive. Methods: In this cohort study, after CT scanning of all patients and subject selection, conventional medical treatment was started as follows and continued for three consecutive months: at first, saline nose wash twice per day, intranasal beclomethasone spray one puff in each nostril twice per day, montelukast 10 mg tablet once daily, a ten-day course of oral prednisolone starting with the dose of 25 mg per day and taper and discontinued thereafter. Sinonasal outcome test 22 (SNOT22) was used for the evaluation of symptom severity. Statistical analyses were performed with SPSS version 23, and data were analyzed using an independent samples T-test, paired T-test, and Receiver operating curve analysis. Results: 25 males and 53 females were enrolled in this study, with an average age of 41.56 ± 11.74 years old (18-36). Aspirin challenge test results were positive in 29 (37.2%) patients. The average SNOT22 scores before the treatment were 52.97 ± 17.73 and 47.04 ± 18.30 in aspirin-sensitive and aspirin-tolerant patients, respectively, and decreased to 27.41 ± 16.61 and 24.88 ± 16.72 in aspirin-sensitive and aspirin-tolerant patients after the treatment, respectively. There was no significant difference in SNOT22 scores between the groups. Conclusion: The severity of symptoms before treatment and clinical improvement after treatment are not good predictors of N-ERD.

Comparison of circulating miR-148a and miR-126 with autoantibodies as biomarkers of lupus nephritis in patients with SLE.

Lupus nephritis (LN) is the main manifestation of systemic Lupus Erythematosus (SLE). MicroRNAs (miRNAs) and autoantibodies could be suitable candidate biomarkers of LN. This study evaluates the expression of circulating miR-148a and miR-126 along with anti-dsDNA, anti-C1q, and anti-C3b autoantibodies in SLE patients with LN (SLE + LN). 30 women with SLE, 30 women with SLE + LN, and 25 women as healthy controls (HCs) were enrolled in this study. The plasma expression of selected miRNAs was evaluated by real-time PCR. The serum level of anti-dsDNA, C1q, and C3b antibodies was measured by the ELISA. The expression of miR-148a was significantly increased in SLE and SLE+LN groups compared with the control group. No significant difference was found in the expression of miR-126 among the groups. The frequency of autoantibodies was significantly higher in the SLE + LN group than SLE. The Higher levels of circulating miR-148a in the SLE samples compared with the HCs suggest that this miRNA could be a reliable biomarker for SLE patients (with or without LN). Also, autoantibodies against dsDNA, C1q, and, C3 could be used for the prediction of SLE nephritis, independently. However, further studies are needed to confirm these findings.

Development and characterization of a camelid single-domain antibody directed to human CD22 biomarker.

CD22 is a B-cell-specific trans-membrane glycoprotein, which is found on the surface of the most B cells and modulates their function, survival, and apoptosis. Recently, targeting this cell surface biomarker in B-cell malignancies and disorders has attracted a lot of attention. The variable domain of camelid single-chain antibodies (VHH, nanobody) is a form of antibodies with novel properties including small size (15-17 kDa), thermal and chemical stability, high affinity and homology to human antibody sequences. In this study, a novel anti-CD22-specific VHH (Nb) has been developed and characterized by the screening of an immunized phage display library and its binding to CD22+ B cells is evaluated. Produced anti-CD22 VHH had a single protein band about 17 kDa of molecular size in Western blotting and its binding affinity was approximately 9 × 10-9  M. Also, this product had high specificity and it was able to recognize the natural CD22 antigen in CD22+ cell lysate as well as on the cell surface (93%). This anti-CD22 VHH with both high affinity and specificity recognizes CD22 antigen well and can be used in diagnosis and treatment of B cell disorders and malignancies.

An antibody fragment against human delta-like ligand-4 for inhibition of cell proliferation and neovascularization.

OBJECTIVES: Angiogenesis targeting is an attractive approach for cancer treatment. Delta-like ligand 4 (DLL4) plays a pivotal role in neovascular development and its inhibitors have recently entered clinical trials for solid tumors. The aim of this study was to evaluate the possibilities of using anti-DLL4 antibody fragment as an angiogenesis maturation inhibitor. MATERIALS AND METHODS: In this study, a DLL4-specific Nanobody, named 3Nb3, was selected and assessed by western blotting and internalization assays. Functional assessments included MTT, apoptosis, and chicken chorioallantoic membrane (CAM) assays. RESULTS: Based on the results, 3Nb3 specifically binds to DLL4 and internalizes into MKN cell. Furthermore, 3Nb3 significantly inhibited the proliferation of cells and also neovascularization in the CAM. CONCLUSIONS: These data demonstrated the potential of Nanobody for application in targeting DLL4. Our findings may provide a basis for the development of novel therapeutic techniques to inhibit growth and neovascularization of tumors.

Molecular detection of virulence genes in Pseudomonas aeruginosa isolated from children with Cystic Fibrosis and burn wounds in Iran.

Pseudomonas aeruginosa possesses various virulence factors which contribute to the bacterial invasion and toxicity. Moreover, children suffered from Cystic Fibrosis (CF) and burn wounds are at a high risk of various bacterial infections. The aim of this study was to determine the prevalence of virulent genes in P. aeruginosa isolated from children with CF and burn wounds and comparing their virulence genes to figure out the role of every virulent factor in the infections. P. aeruginosa were isolated from sputum, oropharyngeal swabs, and broncho-alveolar lavage (BAL) specimens from CF and burn wounds between June 2013 and June 2014 in Tehran's hospitals. Bacterial genomic DNAs were extracted and uniplex, duplex and multiplex PCR were performed for detection of toxA, algD and plcN, exoS, lasB, plcH genes, respectively. The prevalence rate of virulence genes in P. aeruginosa isolated from CF was; toxA (63.1%), algD (64.6%), plcH (87.7%), plcN (60%), lasB (95.4%) and exoS (70.8%) and virulence genes in P. aeruginosa from burn patients were: toxA (36.9%), algD (70.1%), plcH (79%), plcN (63.1%), lasB (82%) and exoS (21.1%). The prevalence of three virulent genes in P. aeruginosa was higher in CF comparing to burn wound infections. We found that the number of toxA, lasB and exoS were significantly higher in the bacteria which were isolated from children with CF. This finding shows that these virulence factors play an important role in CF infections by P. aeroginosa.

Elevated Levels of T-helper 17-associated Cytokines in Diabetes Type I Patients: Indicators for Following the Course of Disease.

BACKGROUND: Type 1 diabetes (T1D) is thought to involve chronic inflammation, which is manifested by the activation and expression of different inflammatory mediators. Th1- and Th17-associated cytokines are factors that have been shown to exert profound pro-inflammatory activities and have been implicated in the pathogenesis of T1D in mice and humans. OBJECTIVES: Therefore, the aim of this case control study was to determine the serum level of IL-17, IL-21, IL-27, transforming growth factor beta (TGF-ß), and IFN-γ and their reciprocal relationship in Iranian T1D patients. PATIENTS AND METHODS: Blood samples were collected from 48 T1D patients and 49 healthy individuals with no history of malignancies or autoimmune disorders based on simple sampling. The serum levels of IL-17, IL-21, IL-27, TGF-ß, and IFN-γ were measured by the enzyme linked immunosorbent assay (ELISA). RESULTS: The serum levels of IL-17 and IL-21 were significantly higher in T1D patients compared to the healthy individuals (p = 0.005 and 0.01, respectively), but interestingly, the opposite was the case for IL-27 (p < 0.0001). However, there were no significant differences in TGF-ß and IFN-γ between both groups. In addition, IL-17/IFN-γ and IL-17/IL-27 ratios were higher in patients compared to the control group. CONCLUSIONS: Our results indicated dominant Th17-associated IL-17, suggesting a shift from the Treg and Th1 phenotypes toward the Th17 phenotype. Therefore, it can promote inflammation in ß cells in T1D. In addition, it suggests the role of Th17 and Th17/Th1 ratios as a potential contributor to ß cells destruction and the Th17/Th1 response ratio may provide a novel biomarker for rapid T1D diagnosis before the destruction of ß cells and progression of the disease to the clinical end stages.

Assessment of 1,25-dihydroxyvitamin D3 effects on Treg cells in a mouse model of systemic lupus erythematosus.

CONTEXT: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease which is characterized by the presence of auto-reactive T cell and anti-ds DNA antibodies. Treg cells are crucial for maintaining immunologic self-tolerance and are shown to be reduced in SLE patients. 1,25-Dihydroxyvitamin D3 has immunomedulatory effects on the immune system and has recently received substantial attention. OBJECTIVE: In this study we evaluated the effects of 1,25-dihydroxyvitamin D3 on Treg cells and related cytokines in lupus-like induced mice model. MATERIALS AND METHODS: Female Balb/c mice were divided into four groups: Group one: injected with PBS and Freund's adjuvant; Group two: injected with non-activated chromatin; Group three: Lupus-like disease was induced with activated chromatin; Group four: Mice were initially treated for two weeks with 1,25-dihydroxyvitamin D3 and then lupus-like disease was induced. Group five: Four mice from group one were treated with 1,25-dihydroxyvitamin D3 for two weeks after disease establishment. Ten weeks after the last injection the mice were killed and spleens were studied for Treg percentages and expression of cytokine genes. RESULTS: We found that treatment with 1,25-dihydroxyvitamin D3 reduces IL-6 and IL-10 mRNA expression and increases TGF-ß and Foxp3 mRNA expression levels, and also enhances spleen Treg percentage. CONCLUSIONS: The remarkable reduction of IL-6 and IL-10 gene expressions, significant enhancement of TGF-ß and Foxp3 gene expressions, along with an increase in Treg cell population after oral 1,25-dihydroxyvitamin D3 administration suggest a possible role for this vitamin as a prophylactic supplement in SLE.

Aquaporins in colorectal cancer: exploring their role in tumorigenesis, metastasis, and drug response.

Aquaporins (AQPs) are small, integral proteins facilitating water transport across plasma cell membranes in response to osmotic gradients. This family has 13 unique members (AQP0-12), which can also transport glycerol, urea, gases, and other salute small molecules. AQPs play a crucial role in the regulation of different cellular processes, including metabolism, migration, immunity, barrier function, and angiogenesis. These proteins are found to aberrantly overexpress in various cancers, including colorectal cancer (CRC). Growing evidence has explored AQPs as a potential diagnostic biomarker and therapeutic target in different cancers. However, there is no comprehensive review compiling the available information on the crucial role of AQPs in the context of colorectal cancer. This review highlights the significance of AQPs as the biomarker and regulator of tumor cells metabolism. In addition, the proliferation, angiogenesis, and metastasis of tumor cells related to AQPs expression as well as function are discussed. Understanding the AQPs prominent role in chemotherapy resistance is of great importance clinically.

A case report of heterotopic ossifications in abdominal incision scar.

INTRODUCTION: Heterotopic ossification (HO) develops when bone formation appears in soft tissues, usually after an injury or major surgery. Timely and accurately diagnosing of this rare event is essential due to the possibility of misdiagnosis as a maintained foreign body, infection, incisional neoplastic recurrence, and metastatic or primary neoplasms. CASE PRESENTATION: In this study, we present a 57-year-old man who was operated for peritonitis due to perforated appendicitis, and an asymptomatic HO was accidentally found on an incisional line of previous open prostatectomy about 5 years earlier due to benign prostatic hyperplasia. A bone density lesion was seen in the fascia and on the incisional scar of previous surgery. DISCUSSION: HO rarely occurs within an abdominal incision due to surgery. It is reported only within vertical midline incisions and mainly within the first year after the operation. Imaging confirms the diagnosis of HO in previous abdominal surgery scars, which reveals dense vertical calcification along the previous incisional scar. In the case of HO, the exclusive effective management is the entire surgical excision with primary closure, and NSAIDs are the preventive choices. CONCLUSION: HO should be considered in patients presenting with discomfort or palpable mass or even asymptomatic patients with previous abdominal surgeries besides considering relative history such as surgical complications or neoplasms.

Exosomes for CRISPR-Cas9 Delivery: The Cutting Edge in Genome Editing.

Gene mutation correction was challenging until the discovery of clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein (Cas). CRISPR is a new era for genome modification, and this technology has bypassed the limitations of previous methods such as zinc-finger nuclease and transcription activator-like effector nuclease. Currently, this method is becoming the method of choice for gene-editing purposes, especially therapeutic gene editing in diseases such as cardiovascular, neurological, renal, genetic, optical, and stem cell, as well as blood disorders and muscular degeneration. However, finding the optimum delivery system capable of carrying this large complex persists as the main challenge of this technology. Therefore, it would be ideal if the delivery vehicle could direct the introduction of editing functions to specific cells in a multicellular organism. Exosomes are membrane-bound vesicles with high biocompatibility and low immunogenicity; they offer the best and most reliable way to fill the CRISPR/Cas9 system delivery gap. This review presents the current evidence on the molecular mechanisms and challenges of CRISPR/Cas9-mediated genome modification. Also, the role of CRISPR/Cas9 in the development of treatment and diagnosis of numerous disorders, from malignancies to viral infections, has been discussed. Lastly, the focus is on new advances in exosome-delivery technologies that may play a role in CRISPR/Cas9 delivery for future clinical settings.

Immunosenescence and Inflammaging in COVID-19.

Despite knowledge gaps in understanding the full spectrum of the hyperinflammatory phase caused by SARS-CoV-2, according to the World Health Organization (WHO), COVID-19 is still the leading cause of death worldwide. Susceptible people to severe COVID-19 are those with underlying medical conditions or those with dysregulated and senescence-associated immune responses. As the immune system undergoes aging in the elderly, such drastic changes predispose them to various diseases and affect their responsiveness to infections, as seen in COVID-19. At-risk groups experience poor prognosis in terms of disease recovery. Changes in the quantity and quality of immune cell function have been described in numerous literature sites. Impaired immune cell function along with age-related metabolic changes can lead to features such as hyperinflammatory response, immunosenescence, and inflammaging in COVID-19. Inflammaging is related to the increased activity of the most inflammatory factors and is the main cause of age-related diseases and tissue failure in the elderly. Since hyperinflammation is a common feature of most severe cases of COVID-19, this pathway, which is not fully understood, leads to immunosenescence and inflammaging in some individuals, especially in the elderly and those with comorbidities. In this review, we shed some light on the age-related abnormalities of innate and adaptive immune cells and how hyperinflammatory immune responses contribute to the inflammaging process, leading to clinical deterioration. Further, we provide insights into immunomodulation-based therapeutic approaches, which are potentially important considerations in vaccine design for elderly populations.

Mesenchymal stem cell-derived exosomes for managing graft-versus-host disease: An updated view.

Graft-versus-host disease (GvHD) is the most common complication after stem cell transplantation, and also it is one of the primary limiting factors for the use of hematopoietic stem cell transplantation (HSCT) in the treatment of hematologic cancers. GvHD, a systemic inflammatory disease, is caused by donor T cells recognizing the recipient's foreign antigens. In addition, an immune dysregulation, caused by autoreactive immune cells, complicates potent inflammatory process following HSCT. While there is no one approved treatment method for GvHD, corticosteroids are the most common first-line treatment. Exosomes are biological vesicles between 30 and 120 nm in diameter, which carry various biologically active molecules. They are known to play a key role in the paracrine effect of mesenchymal stem cells with therapeutic and tissue repair effects, including an immunosuppressive potential. Exosomes are unable to replicate themselves but because of their small size and fluid-like structure, they can pass through physiological barriers. Exosome are relatively easy to prepare and they can be quickly sterilized by a filtration process. Administration of exosomes, derived from mesenchymal stem cells, effectively reduced GvHD symptoms and significantly increased HSCT recipients' survival. Mesenchymal stem cell-derived exosome therapy reduced clinical symptoms of GvHD in patients after HSCT. Studies in patients with GvHD described that that mesenchymal stem cell-derived exosomes inhibited the release of IFN-γ and TNF-α by activated natural killer (NK cells), thereby reducing the lethal function of NK cells and inflammatory responses. Current review provides a comprehensive overview about the use of mesenchymal stem cells and their derived exosomes for the treatment of GvHD.

The Relationship between Fear of COVID-19 and Self-Medication and the Rate of Antibiotic Use in Patients Referred to COVID-19.

Introduction: The coronavirus pandemic can cause anxiety and stress among people, which can make them practice self-medication. This study aimed to investigate the relationship between fear of corona and self-medication and antibiotics use. Methods: In a convenience sampling method, 250 people referring to COVID-19 centers including 16-hour comprehensive health services in Kermanshah, Iran, who tested positive and were not hospitalized were extracted from the SIB system. Data collection tools include three questionnaires including corona fear questionnaire, self-medication questionnaire, and self-medication by antibiotic questionnaire and an information form including demographic characteristics. Data were analyzed by SPSS version 25. Results: The prevalence of self-medication was 59.6%. There was a significant correlation between self-medication and gender (P value <0.05) and education level (P value <0.05); the most common reason for self-medication was easy access to medicines through pharmacy drug stores. The mean score of fear of corona was higher in women and those who were not in a good financial position due to a lack of suitable economic status to see a doctor. Conclusion: There was a direct and significant relationship between self-medication and self-medication by antibiotics. 59.6% of the participants used medicines themselves, buying over-the-counter in pharmacies. Also, there was a statistically significant difference between the mean score of corona fear in terms of not having a suitable economic status to see a doctor. This indicates that the lack of proper economic status among people with the coronavirus positive test to see a doctor increases the fear of the disease.

Mesenchymal stem cells- derived exosomes inhibit the expression of Aquaporin-5 and EGFR in HCT-116 human colorectal carcinoma cell line.

BACKGROUND: Aquaporins are channel proteins, form pores in the membrane of biological cells to facilitate the transcellular and transepithelial water movement. The role of Aquaporins in carcinogenesis has become an area of interest. In this study, we aimed to investigate the effects of adipose-derived mesenchymal stem cells secreted exosomes on the expression of aquaporin 5 and EGFR genes in the HCT-116 tumor cell line. METHODS AND RESULTS: Surface antigenic profile of Ad-MSCs was evaluated using specific markers. Exosomes were purified from the Ad-MSc supernatant while the quality and the shape of isolated exosomes were assessed by western blot and transmission electron microscopy (TEM) respectively. HCT-116 cells were co-cultured with MSC-conditioned medium (MSC-CM) and/or with 100 µg/ml of MSC-derived exosomes for 48 h and. Real-time PCR was carried out to determine the expression of aquaporin5 and EGFR in HCT-116. Relative expression levels were calculated using the 2-ΔΔct method. Our result showed that AQP5 and EGFR mRNA levels were significantly reduced in CM and/or exosomes treated HCT116 compare to the control group (P-value < 0.05). CONCLUSION: The current study showed that MSC derived exosomes could inhibit expression of two important molecules involved in tumor progression. Hence it seems MSCs-derived exosomes may hold a hopeful future as drug delivery vehicles which need the furtherer investigation.

Anti-cancer Activity of Chrysin in Cancer Therapy: a Systematic Review.

Chrysin is a natural bioactive compound that is extracted from many trees, honey, and propolis. Chrysin has several pharmacological activities such as anti-inflammatory, anti-cancer, and antioxidant properties. This study was performed to evaluate the anti-cancer activities of chrysin in cancer therapy. The present study was conducted by systematic review of studies published up to August 2021. Related studies were identified by searching Web of Science (WoS), PubMed, Science Direct, SID, MagIran, Scopus, and Google Scholar databases. The keywords of chrysin, cancer, anti-cancer, and cancer therapy were used for searching. The quality of the studies was assessed by the CONSORT checklist. A total of 21 studies were identified. The results of studies showed that chrysin has an anticancer effect by stimulating apoptosis in a wide range of human cells and rats. Chrysin is also an important factor in inhibiting tumor growth and neoplasticity. Chrysin inhibits the growth and proliferation of cancer cells by inducing cytotoxic effects. Therefore, due to the antitumor effects of chrysin and its safety and non-toxicity towards normal cells, this compound can be considered as an adjuvant along with chemotherapeutic agents in cancer treatment.

Type-I interferons in the immunopathogenesis and treatment of Coronavirus disease 2019.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), is currently the major global health problem. Still, it continues to infect people globally and up to the end of February 2022, over 436 million confirmed cases of COVID-19, including 5.95 million deaths, were reported to the world health organization (WHO). No specific treatment is currently available for COVID-19, and the discovery of effective therapeutics requires understanding the effective immunologic and immunopathologic mechanisms behind this infection. Type-I interferons (IFN-Is), as the critical elements of the immediate immune response against viral infections, can inhibit the replication and spread of the viruses. However, the available evidence shows that the antiviral IFN-I response is impaired in patients with the severe form of COVID-19. Moreover, the administration of exogenous IFN-I in different phases of the disease can lead to various outcomes. Therefore, understanding the role of IFN-I molecules in COVID-19 development and its severity can provide valuable information for better management of this disease. This review summarizes the role of IFN-Is in the pathogenesis of COIVD-19 and discusses the importance of autoantibodies against this cytokine in the spreading of SARS-CoV-2 and control of the subsequent excessive inflammation.

Polymer-based drug delivery systems for anticancer drugs: A systematic review.

Recent advances in nanotechnology sciences lead to the development of new treatment approaches for various diseases such as cancer. Nanotechnology advances can potentially minimize the side effects of drugs through the employment of effective and controlled drug delivery systems (DDSs). Polymers are optimal tools providing drug delivery mechanisms through the unique features of pharmacokinetics, circulation time, biocompatibility, and biodegradability. This systematic review aimed to evaluate polymer-based DDSs for anticancer drugs and their various therapeutic applications in cancer treatment. This study was conducted with no time limitation by November 2021. Related articles were collected through a deep search in English and Persian databases of SID, MagIran, Scopus, Web Of Science (WoS), PubMed, Science Direct, and Google Scholar. Keywords included drug delivery system, anticancer agent, polymeric nanostructure-based drug delivery, polymer-based drug delivery, and polymeric system. As the results showed, polymeric nanoparticles (PNPs) have influential roles in cancer treatment than conventional chemotherapy procedures. PNPs can reduce cytotoxicity following chemotherapy drug administration, improve the solubility characteristics of these therapeutic agents and inhibit the rate of tumor growth.
