Abstract
The DNA damage response (DDR) is a crucial cellular signaling pathway activated in response to DNA damage, including damage caused by chemotherapy. Chemoresistance, which refers to the resistance of cancer cells to the effects of chemotherapy, poses a significant challenge in cancer treatment. Understanding the relationship between DDR and chemoresistance is vital for devising strategies to overcome this resistance and improve treatment outcomes. Long non-coding RNAs (lncRNAs) are a class of RNA molecules that do not code for proteins but play important roles in various biological processes, including cancer development and chemoresistance. RNA-binding proteins (RBPs) are a group of proteins that bind to RNA molecules and regulate their functions. The interaction between lncRNAs and RBPs has been found to regulate gene expression at the post-transcriptional level, thereby influencing various cellular processes, including DDR signaling pathways. Multiple studies have demonstrated that lncRNAs can interact with RBPs to modulate the expression of genes involved in cancer chemoresistance by impacting DDR signaling pathways. Conversely, RBPs can regulate the expression and function of lncRNAs involved in DDR. Exploring these interactions can provide valuable insights for the development of innovative therapeutic approaches to overcome chemoresistance in cancer patients. This review article aims to summarize recent research on the interaction between lncRNAs and RBPs during cancer chemotherapy, with a specific focus on DDR pathways.

Abstract
Breast cancer is a commonly known cancer type and the leading cause of cancer death among females. One of the unresolved problems in cancer treatment is the increased resistance of the tumor to existing treatments, which is a direct result of apoptotic defects. Calculating an alternative to cell death (autophagy) may be the ultimate solution to maximizing cancer cell death. Our aim in this study was to investigate the potential of free nanoparticles (un-drug-loaded) in the induction or inhibition of autophagy and consider this effect on the therapy process. When the studies met the inclusion criteria, the full texts of all relevant articles were carefully examined and classified. Of the 25 articles included in the analysis, carried out on MCF-7, MDA-MB-231, MDA-MB-231-TXSA, MDA-MB-468, SUM1315, and 4T1 cell lines. Twenty in vitro studies and five in vivo/in vitro studies applied five different autophagy tests: Acridine orange, western blot, Cyto-ID Autophagy Detection Kit, confocal microscope, and quantitative polymerase chain reaction. Nanoparticles (NPs) in the basic format, including Ag, Au, Y2 O3 , Se, ZnO, CuO, Al, Fe, vanadium pentoxide, and liposomes, were prepared in the included articles. Three behaviors of NPs related to autophagy were seen: induction, inhibition, and no action. Screened and presented data suggest that most of the involved free NPs (metallic NPs) in this systematic review had reactive oxygen species-mediated pathways with autophagy induction (36%). Also, PI3K/Akt/mTOR and MAPK/ERK signaling pathways were mentioned in just four studies (16%). An impressive percentage of studies (31%) did not examine the NP-related autophagy pathway.

Abstract
Noncoding RNAs (ncRNAs) are engaged in key cell biological and pathological events, and their expression alteration is connected to cancer progression both directly and indirectly. A huge number of studies have mentioned the significant role of ncRNAs in cancer prevention and therapy that make them an interesting subject for cancer therapy. However, there are several limitations, including delivery, uptake, and short half-life, in the application of ncRNAs in cancer treatment. Exosomes are introduced as promising options for the delivery of ncRNAs to the target cells. In this review, we will briefly discuss the application and barriers of ncRNAs. After that we will focus on exosome-based ncRNAs delivery and their advantages as well as the latest achievements in drugging ncRNAs with exosomes.

Abstract
Periodontal disease is the most common oral disease. This disease can be considered as an inflammatory disease. The immune response to bacteria accumulated in the gum line plays a key role in the pathogenesis of periodontal disease. In addition to immune cells, periodontal ligament cells and gingival epithelial cells are also involved in the pathogenesis of this disease. miRNAs which are small RNA molecules with around 22 nucleotides have a considerable relationship with the immune system affecting a wide range of immunological events. These small molecules are also in relation with periodontium tissues especially periodontal ligament cells. Extensive studies have been performed in recent years on the role of miRNAs in the pathogenesis of periodontal disease. In this review paper, we have reviewed the results of these studies and discussed the role of miRNAs in the immunopathogenesis of periodontal disease comprehensively. miRNAs play an important role in the pathogenesis of periodontal disease and maybe helpful therapeutic targets for the treatment of periodontal disease.

Abstract
Inflammatory bowel disease is a chronic inflammatory disease and has periods of recurrence and remission. Improper immune responses to gut flora bacteria, along with genetic susceptibility, appear to be involved in causing this complex disease. It seems dysbiosis and oxidative stress may also be involved in IBD pathogenesis. A significant number of clinical studies have shown an interesting association between sleep disturbances and IBD. Studies in animal models have also shown that sleep deprivation has a significant effect on the pathogenesis of IBD and can aggravate inflammation. These interesting findings have drawn attention to melatonin, a sleep-related hormone. Melatonin is mainly produced by the pineal gland, but many tissues in the body, including the intestines, can produce it. Melatonin can have an interesting effect on the pathogenesis of IBD. Melatonin can enhance the intestinal mucosal barrier, alter the composition of intestinal bacteria in favor of bacteria with anti-inflammatory properties, regulate the immune response, alleviate inflammation and attenuate oxidative stress. It seems that, melatonin supplementation is effective in relieving inflammation and healing intestinal ulcers in IBD animal models. Some clinical studies have also shown that melatonin supplementation as an adjuvant therapy may be helpful in reducing disease activity in IBD patients. In this review article, in addition to reviewing the effects of sleep disturbances and melatonin on key mechanisms involved in the pathogenesis of IBD, we will review the findings of clinical studies regarding the effects of melatonin supplementation on IBD treatment.

Abstract
Increasing bone resorption followed by decreasing bone mineralization are hallmarks of bone degeneration, which mostly occurs in the elderly population and post-menopausal women. The use of mesenchymal stem cells (MSCs) has raised many promises in the field of bone regeneration due to their high osteoblastic differentiation capacity and easy availability from abundant sources. A variety of compounds, including growth factors, cytokines, and other internal factors, have been combined with MSCs to increase their osteoblastic differentiation capacity. One of these factors is melatonin, whose possible regulatory role in bone metabolism and formation has recently been suggested by many studies. Melatonin also is a potential signaling molecule and can affect many of the signaling pathways involved in MSCs osteoblastic differentiation, such as activation of PI3K/AKT, BMP/Smad, MAPK, NFkB, Nrf2/HO-1, Wnt, SIRT/SOD, PERK/ATF4. Furthermore, melatonin in combination with other components such as strontium, vitamin D3, and vitamin K2 has a synergistic effect on bone microstructure and improves bone mineral density (BMD). In this review article, we aim to summarize the regulatory mechanisms of melatonin in osteoblastic differentiation of MSCs and underling involved signaling pathways as well as the clinical potential of using melatonin in bone degenerative disorders.

Abstract
LncRNAs and miRNAs are the two most important non-coding RNAs, which have been identified to be associated with cancer progression or prevention. The dysregulation of lncRNAs conducts tumorigenesis and metastasis in different ways. One of the mechanisms is that lncRNAs interact with miRNAs to regulate distinct cellular and genomic processes and cancer progression. LncRNA SNHG7 as an oncogene sponges miRNAs and develops lncRNA-miRNA-mRNA axes, leading to the regulation of several signaling pathways such as Wnt/β-Catenin, PI3K/AKT/mTOR, SIRT1, and Snail-EMT. Therefore, in this article, after a brief overview of lncRNA SNHG7-miRNA-mRNA axes' contribution to cancer development, we will discuss the role of lncRNA SNHG7 in the genes expression and signaling pathways related to cancers development via acting as a ceRNA.

Abstract
Introduction: Doxorubicin (DOX) is one of the most common drugs in cancer treatment. However, its partial solubility along with the high incidence of side effects remains a challenge to tackle. To address these issues, we designed a formulation based on graphene oxide (GO) and used it as an anticancer drug delivery system. Methods: The physical and chemical properties of the formulation were studied using FTIR, SEM, EDX, Mapping, and XRD. Release studies in the in vitro condition were used to evaluate the pH sensitivity of drug release from nanocarriers. Other in vitro studies, including uptake assay, MTT, and apoptosis assay were carried out on the osteosarcoma (cell line. Results: In vitro release studies confirmed that the synthesized formulation provides a better payload release profile in acidic conditions, which is usually the case in the tumor site. On the OS cell line, the cytotoxicity of the DOX-loaded nanocarrier (IC50=0.293 μg/mL) and early apoptosis rate (33.80 % ) were higher in comparison to free DOX (IC50=0.472 μg/mL, and early apoptosis rate= 8.31 % ) after 48 hours. Conclusion: In summary, our results suggest a DOX-loaded graphene oxide carrier as a potential platform for targeting cancer cells.

Abstract
The CRISPR/Cas9 system is an RNA-based adaptive immune system in bacteria and archaea. Various studies have shown that it is possible to target a wide range of human genes and treat some human diseases, including cancers, by the CRISPR/Cas9 system. In fact, CRISPR/Cas9 gene editing is one of the most efficient genome manipulation techniques. Studies have shown that CRISPR/Cas9 technology, in addition to having the potential to be used as a new therapeutic approach in the treatment of cancers, can also be used to enhance the effectiveness of existing treatments. Undoubtedly, the issue of drug resistance is one of the main obstacles in the treatment of cancers. Cancer cells resist anticancer drugs by a variety of mechanisms, such as enhancing anticancer drugs efflux, enhancing DNA repair, enhancing stemness, and attenuating apoptosis. Mutations in some proteins of different cellular signaling pathways are associated with these events and drug resistance. Recent studies have shown that the CRISPR/Cas9 technique can be used to target important genes involved in these mechanisms, thereby increasing the effectiveness of anticancer drugs. In this review article, studies related to the applications of this technique in overcoming drug resistance in cancer cells will be reviewed. In addition, we will give a brief overview of the limitations of the CRISP/Cas9 gene-editing technique.

Abstract
AbstractChemotherapy, which is one of the common treatments for osteosarcoma (OS), has
many side effects and in some cases has low effectiveness due to
chemoresistance, hence it is vital to study new therapies for OS. In this
regard, we combined melatonin with cisplatin and evaluate their effect on MG63
OS cells. Since melatonin has anti-cancer properties, we hypothesized that its
combination with cisplatin could increase the effectiveness of cisplatin.
Firstly, MTT assay was used to evaluate the cell viability and cytotoxicity of
cisplatin on MG63 cells and the results showed that melatonin in combination
with cisplatin increases the sensitivity of MG63 cells to cisplatin. In
addition, qRT-PCR results showed that the expressions of miR-181 and P53, CYLD,
CBX7 and BCL2 genes change in MG63 cells after treatment with the combination of
cisplatin and melatonin, so that the expression of P53, CYLD and CBX7 increased
and the expression of BCL2 and miR-181b decreases significantly. Furthermore,
analysis of Annexin V/FITC assay data revealed that the rate of
apoptosis in MG63 OS cell line remarkably promoted after treated with cisplatin
and melatonin combination. As a result, our findings show that melatonin in
combination with cisplatin increases the effectiveness of cisplatin in
osteosarcoma cells and this study provides a new therapeutic approach for
OS.

Abstract
Malignant mesothelioma (MMe) is an aggressive neoplasm that occurs through the transformation of mesothelial cells. Asbestos exposure is the main risk factor for MMe carcinogenesis. Other important etiologies for MMe development include DNA damage, over-activation of survival signaling pathways, and failure of DNA damage response (DDR). In this review article, first, we will describe the most important signaling pathways that contribute to MMe development and their interaction with DDR. Then, the contribution of DDR failure in MMe progression will be discussed. Finally, we will review the latest MMe therapeutic strategies that target the DDR pathway.

Abstract
Inflammatory Bowel Disease (IBD) is a chronic inflammatory disease with relapse and remission periods. Ulcerative colitis and Crohn's disease are two major forms of the disease. IBD imposes a lot of sufferings on the patient and has many consequences; however, the most important is the increased risk of colorectal cancer, especially in patients with Ulcerative colitis. This risk is increased with increasing the duration of disease, thus preventing the progression of IBD to cancer is very important. Therefore, it is necessary to know the details of events contributed to the progression of IBD to cancer. In recent years, the importance of miRNAs as small molecules with 20-22 nucleotides has been recognized in pathophysiology of many diseases, in which IBD and colorectal cancer have not been excluded. As a result, the effectiveness of these small molecules as therapeutic target is hopefully confirmed. This paper has reviewed the related studies and findings about the role of miRNAs in the course of events that promote the progression of IBD to colorectal carcinoma, as well as a review about the effectiveness of some of these miRNAs as therapeutic targets.

Abstract
INTRODUCTION Osteosarcoma (OS) is one of the most common bone neoplasms in adolescents. Notable short- and long-term toxic effects of OS chemotherapy regimens have been reported. Hence, new chemotherapeutic agents with the ability to potentiate OS chemotherapy drugs and protect non-tumorous tissues are required. METHODS Saos-2 cells were treated with Methotrexate (MTX) and Quercetin (Que) (a polyphenolic flavonoid with anti-tumor effects) alone and in combination. MTT assay was performed to investigate the cytotoxicity of the drugs. Moreover, apoptosis-involved genes, including miR-223, p53, BCL-2, CBX7, and CYLD expression were analyzed via qRT-PCR. Annexin V-FITC/PI kit was employed to assess the apoptosis rate. RESULTS The MTT results showed that Que increases MTX cytotoxicity on OS cells. The measured IC50s are 142.3 µM for QUE and 13.7 ng/ml for MTX. A decline in MTX IC50 value was observed from 13.7 ng/ml to 8.45 ng/ml in the presence of Que. Moreover, the mRNA expression outcomes indicated that the combination therapy significantly up-regulates the tumor suppressor genes, such as p53, CBX7, and CYLD, and declines anti-apoptotic genes BCL-2 and miR-223, which can lead to proliferation inhibition and apoptosis inducement. Furthermore, the apoptosis rate increased significantly from 6.03% in the control group to 38.35% in Saos-2 cells that were treated with the combination of MTX and Que. CONCLUSION Que, with the potential to boost the anticancer activity of MTX on Saos-2 cancer cells through proliferation inhibition and apoptosis induction, is a good candidate for combination therapy.

Abstract
Osteosarcoma (OS) is the most common bone malignancy that occurs most often in young adults, and adolescents with a survival rate of 20% in its advanced stages. Nowadays, increasing the effectiveness of common treatments used in OS has become one of the main problems for clinicians due to cancer cells becoming resistant to chemotherapy. One of the most important mechanisms of resistance to chemotherapy is through increasing the ability of DNA repair because most chemotherapy drugs damage the DNA of cancer cells. DNA damage response (DDR) is a signal transduction pathway involved in preserving the genome stability upon exposure to endogenous and exogenous DNA-damaging factors such as chemotherapy agents. There is evidence that the suppression of DDR may reduce chemoresistance and increase the effectiveness of chemotherapy in OS. In this review, we aim to summarize these studies to better understand the role of DDR in OS chemoresistance in pursuit of overcoming the obstacles to the success of chemotherapy.

Abstract
INTRODUCTION Osteosarcoma (OS) is a primary bone sarcoma with a high recurrence rate and poorer prognosis. The application of natural agents in combinational therapies can increase the efficacy of treatment and decrease the side effects. Herein, we aimed to evaluate the effects of Thymoquinone (TQ) combined with Cisplatin on apoptosis and its underlying mechanisms in the Saos-2 cells. METHODS The effects of TQ and Cisplatin on Saos-2 cell viability were measured using an MTT assay. Western blotting was applied for the measurement of γH2AX protein expression. The expression levels of 8-Hydroxy-2'-deoxyguanosine (8-oxo-dG) were evaluated by enzyme-linked immunosorbent assay (ELISA). DCFH-DA fluorescence dye was used to detect reactive oxygen species (ROS) formation. For evaluation of apoptosis, flow cytometry was employed. RESULTS TQ dramatically promotes the cytotoxic effects of Cisplatin. TQ considerably enhanced the expression levels of 8-oxo-dG and γ-H2AX in Saos-2 cells. After TQ treatment, ROS levels were increased; furthermore, TQ treatment resulted in the potentiation of Cisplatin-induced apoptosis in Saos-2 cells compared to either TQ or Cisplatin treated cells. CONCLUSION In general, TQ plus Cisplatin resulted in potentiated cellular cytotoxicity by increasing ROS level and inducing oxidative DNA damage, leading to the potent induction of apoptosis in tumor cells.

Abstract
Long non-coding RNAs (lncRNAs) have received particular attention in the last decade due to its engaging in carcinogenesis and tumorigenesis. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a lncRNA that plays physiological and pathological roles in many aspects of genome function as well as biological processes involved in cell development, differentiation, proliferation, invasion, and migration. In this article, we will review the effects of lncRNA MALAT1 on the progression of six prevalent human cancers by focusing on MALAT1 ability to regulate post-transcriptional modification and signaling pathways.

Abstract
The cellular genome is frequently subjected to abundant endogenous and exogenous factors that induce DNA damage. Most of the Phosphatidylinositol 3-kinase-related kinases (PIKKs) family members are activated in response to DNA damage and are the most important DNA damage response (DDR) proteins. The DDR system protects the cells against the wrecking effects of these genotoxicants and repairs the DNA damage caused by them. If the DNA damage is severe, such as when DNA is the goal of chemo-radiotherapy, the DDR drives cells toward cell cycle arrest and apoptosis. Some intracellular pathways, such as PI3K/Akt, which is overactivated in most cancers, could stimulate the DDR process and failure of chemo-radiotherapy with the increasing repair of damaged DNA. This signaling pathway induces DNA repair through the regulation of proteins that are involved in DDR like BRCA1, HMGB1, and P53. In this review, we will focus on the crosstalk of the PI3K/Akt and PIKKs involved in DDR and then discuss current achievements in the sensitization of cancer cells to chemo-radiotherapy by PI3K/Akt inhibitors.

Abstract
In recent years, knowledge of cardiac regeneration mechanisms has dramatically expanded. Regeneration can replace lost parts of organs, common among animal species. The heart is commonly considered an organ with terminal development, which has no reparability potential during post-natal life; however, some intrinsic regeneration capacity has been reported for cardiac muscle, which opens novel avenues in cardiovascular disease treatment. Different endogenous mechanisms were studied for cardiac repairing and regeneration in recent decades. Survival, proliferation, inflammation, angiogenesis, cell-cell communication, cardiomyogenesis, and anti-aging pathways are the most important mechanisms that have been studied in this regard. Several in vitro and animal model studies focused on proliferation induction for cardiac regeneration reported promising results. These studies have mainly focused on promoting proliferation signaling pathways and demonstrated various signaling pathways such as Wnt, PI3K/Akt, IGF-1, TGF-β, Hippo, and VEGF signaling cardiac regeneration. Therefore, in this review, we intended to discuss the connection between different critical signaling pathways in cardiac repair and regeneration.

Abstract
The third most common malignancy has been identified as Colorectal cancer (CRC) that conducive to death in most cases. Chemoresistance is a common obstacle to CRC treatment. Circulating exosomal microRNAs (miRNAs) have been shown to reverse chemo-resistance and are promising biomarkers for CRC. The capacity of engineered exosomes to cross biological barriers and deliver functional miRNAs could be used to achieve these proposes. The object of this review is the investigation of the role of exosomal miRNA in the chemo-resistance, diagnosis, and prognosis of CRC. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, electronic databases, PubMed, EMBASE, Web of Science, Scopus were searched from January 1990 to November 2020. Ultimately, eight articles included five in vitro (16 cell lines) and three in vivo examinations. Three studies demonstrated that increasing or decreasing mRNA expression was associated with increasing and decreasing cell proliferation in vitro. The presence of miRNA in two studies increased the sensitivity of the drug and exhibited a considerable growth inhibitory effect on cancer cell proliferation. The apoptotic rate was significantly increased in four studies by increased mRNA expression and reduced mrna expression. Tumor volume of xenograft models in three studies suppressed by antitumor miRNA activity. In contrast, anti-miRNA activity in one study decreased the tumor volume. Exosomal miRNAs can be regulators of chemo-resistance and predict adverse outcomes in CRC patients. In sum, exosomes containing miRNAs can be a promising biomarker for the prognosis and diagnosis of CRC. Subsequent research should be a focus on delineating the function of exosomal miRNA before clinical use.

Abstract
Osteosarcoma (OS) is an adolescent and young adult malignancy that mostly occurs in long bones. The treatment of OS is still a big challenge for clinicians due to increasing chemoresistance, and many efforts are being made today to find more beneficial treatments. In this regard, the use of microRNAs has shown a high capacity to develop promising therapies. By targeting cancer-involved signaling pathways, microRNAs reduce the cellular level of these protein pathways; thereby reducing the growth and invasion of tumors, and even leading cancer cells to apoptosis. One of these oncogenic pathways that play an important role in OS development and can be targeted by microRNAs is the Wnt/β-catenin signaling pathway. Hence, the first goal of this review article is to explain the cross-talk of microRNAs and the Wnt/β-catenin signaling in OS and then discussing recent findings of the use of microRNAs as a therapeutic approach in OS.

Abstract
Respiratory viral infections are common respiratory diseases. Influenza viruses, RSV and SARS-COV2 have the potential to cause severe respiratory infections. Numerous studies have shown that unregulated immune response to these viruses can cause excessive inflammation and tissue damage. Therefore, regulating the antiviral immune response in the respiratory tract is of importance. In this regard, recent years studies have emphasized the importance of vitamin D in respiratory viral infections. Although, the most well-known role of vitamin D is to regulate the metabolism of phosphorus and calcium, it has been shown that this vitamin has other important functions. One of these functions is immune regulation. Vitamin D can regulate the antiviral immune response in the respiratory tract in order to provide an effective defense against respiratory viral infections and prevention from excessive inflammatory response and tissue damage. In addition, this vitamin has preventive effects against respiratory viral infections. Some studies during the COVID-19 pandemic have shown that vitamin D deficiency may be associated with a higher risk of mortality and sever disease in patients with COVID-19. Since, more attention has recently been focused on vitamin D. In this article, after a brief overview of the antiviral immune response in the respiratory system, we will review the role of vitamin D in regulating the antiviral immune response comprehensively. Then we will discuss the importance of this vitamin in influenza, RSV, and COVID-19.

Abstract
The melatonin hormone secreted by the pineal gland is involved in physiological functions such as growth and maturation, circadian cycles, and biological activities including antioxidants, anti-tumor, and anti-ischemia. Melatonin not only interacts with proteins but also has functional effects on regulatory RNAs such as long non-coding RNAs (lncRNAs) and microRNAs (miRNAs). In this study, we overview various physiological and pathological conditions affecting melatonin through lncRNA and miRNA. The information compiled herein will serve as a solid foundation to formulate ideas for future mechanistic studies on melatonin. It will also provide a chance to more clarify the emerging functions of the non-coding transcriptome.

Abstract
The safe development of nanotechnology and usage of nanoparticles (NPs) require the cellular toxicity examination of these NPs. Systematic studies are necessary to collect related data and comparison of the physicochemical features of NPs and their effects on cellular viability on model systems. In the present study, we systematically reviewed original studies, which investigated the cytotoxic effects and apoptosis of free NPs (loaded with doxorubicin (Dox)/or methotrexate (MTX)) via in vitro models. Articles were systematically collected by screening the literature published online in the following databases; PUBMED and SCOPUS and Web of Science and EMBASE. 23 in vitro cytotoxicity studies with 8 apoptosis examinations were found on osteosarcoma (OS) cell lines (mostly on MG-63). 43.47% of the synthesized NPs (10 studies) showed no cytotoxicity to OS cells. 39.13% of the synthesized NPs (9 studies) showed time and/or concentration related-cytotoxicity. Potent cytotoxic synthesized NP did not state. Significance difference between the half-maximal inhibitory concentration (IC50) of drug and drug/NP reported in all studies. Involved NPs in this systematic review for delivery of Dox/or MTX to OS cells have higher safety index and biocompatibility, although small and positively charged NPs acted more toxic in comparison to larger and negative ones, apoptosis rate like cytotoxicity index was notable in drug/NP group, to apply them in clinical works. Future studies are required to address the mechanisms involved in cytotoxicity and apoptosis with a special focus on in vivo investigations.

Abstract
The liver is one of the significant regenerative organs in the body. Nevertheless, underlying molecular mechanisms regulating liver repair and regeneration following resection or damage remain largely unknown. The Notch signaling pathway is a profoundly evolutionarily well-conserved cell signaling system that plays mostly in multicellular organisms' development. Malfunctions in this pathway lead to the progression of several liver disorders, including hepatoblastoma (HB), cholangiocarcinoma (CCA), hepatocellular carcinoma (HCC), and so on. Notch pathway plays a fundamental role in cell fate during the embryonic stage's progression to the adult stage in liver tissue. Modulation of Notch signaling may be used in the vast array of patients who succumb to cirrhosis owing to chronic hepatitis by virus infection. This review describes the underlying mechanisms of the Notch signaling pathway in liver development and regeneration briefly and discusses how this pathway leads to better liver disorders in the clinic.

Abstract
According to global statistics, cancer is the second leading cause of death worldwide. Because of the heterogeneity of cancer, single-drug therapy has many limitations due to low efficacy. Therefore, combination therapy with two or more therapeutic agents is being arisen. One of the most important approaches in cancer therapy is the shot down of key genes involved in apoptotic processes and cell cycle. In this regard, siRNA is a good candidate, a highly attractive method to suppressing tumor growth and invasion. Combination therapy with siRNAs and chemotherapeutic agents can overcome the multidrug resistance and increase apoptosis. The efficient delivery of siRNA to the target cell/tissue/organ has been a challenge. To overcome these challenges, the presence of suitable delivery systems by using nanoparticles is interesting. In this review, we discuss the current challenges for successful RNA interference. Also, we suggested proper a strategy for delivering siRNA that can be useful in targeting therapy. Finally, the combination of a variety of anticancer drugs and siRNA through acceptable delivery systems and their effects on cell cycle and apoptosis will be evaluated.

Abstract
Regenerative medicine and tissue engineering have been considered pioneer fields in the life sciences, with an ultimate goal of restoring or switching lost or impaired body parts. Graphene oxide (GO) is the product of graphene oxidation and presents a great opportunity to make substantial progress in the field of regenerative medicine; for example, it supports the possibility of creating a cellular niche for stem cells on a nanoparticle surface. GO creates a fascinating structure for regulating stem cell behavior, as it can potentially applied to the noninvasive chase of stem cells in vivo, the liberation of active biological factors from stem cell-containing delivery systems, and the intracellular delivery of factors such as growth factors, DNA, or synthetic proteins in order to modulate stem cell differentiation and proliferation. Due to the interesting physicochemical properties of GO and its possible usage in tissue engineering approaches, the present review aims to elaborate on the ways in which GO can improve current regenerative strategies. In this respect, the applicability of GO to the repair and regeneration of various tissues and organs, including cardiac muscle, skeletal muscle, and nervous, bone, cartilage, adipose, and skin tissues, is discussed.

Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most common gastrointestinal malignancies with a significant mortality rate. Despite the great advances in cancer treatment in the last few decades, effective treatment of CRC is still under challenge. One of the main problems associated with CRC treatment is the resistance of cancer cells to chemotherapy drugs. METHODS Many studies have been carried out to identify CRC chemoresistance mechanisms, and shed light on the role of ATP-binding cassette transporters (ABC transporters), enzymes as thymidylate synthase, some signaling pathways, and cancer stem cells (CSC) in chemoresistance and failed CRC chemotherapies. Other studies have also been recently carried out to find solutions to overcome chemoresistance. Some of these studies have identified the role of miRNAs in chemoresistance of the CRC cells and the effective use of these micro-molecules to CRC treatment. RESULTS Considering the results of these studies, more focus on miRNAs likely leads to a proper solution to overcome CRC chemoresistance. CONCLUSION The current study has reviewed the related literature while discussing the efficacy of miRNAs as potential clinical tools for overcoming CRC chemoresistance and reviewing the most important chemoresistance mechanisms in CRC cells.

Abstract
Regarding the importance of genetic and epigenetic factors in regulation of aging process, different expression pattern of non-coding RNAs in aging could be investigated. Accordingly, micro RNAs (miRNAs) with a wide range of physiological functions as well as a significant footprint in many diseases have been demonstrated to be down or upregulated during the aging process. Therefore, age-associated microRNAs and their targets have potentially detected the accelerated aging and predicted the risks for age-related diseases. Polyphenols as important antioxidants in human dietary observed in fruits and some beverages have beneficial effects on longevity and aging. Considering miRNAs as an interesting mediator in modulating polyphenols' biological effects, targeting miRNAs which is using polyphenols could be a novel strategy for aging.

Abstract
Several books are available that describe how to construct control charts. Unfortunately none of these books show how to adjust control charts for the severity of the patients' illness. Without such adjustments control charts not only loose face validity but could lead to wrong conclusions. In this article we provide a step-by-step guide regarding how to control for changes in patients' severity of illness across time periods. We illustrate the use of the approach in examining falls in nursing homes. A control chart was constructed to compare observed falls to the residents' risk of fall measured on admission. Analysis led to conclusions radically different from an unadjusted chart.

Abstract
BACKGROUND Studies focusing on the impact of improvement efforts on the organization have yielded mixed results, which has increased interest in comparing the processes of improvement used. Data for a convenience sample of 92 quality improvement (QI) projects in 32 organizations were gathered from interviews and self-reported surveys from 1998 to 2000. A self-administered questionnaire was developed to measure 70 characteristics of improvement projects. RESULTS Most (80%) of the improvement projects were conducted by hospitals or clinics affiliated with hospitals. The projects took an average of 13 months from the team's first meeting to the end of the pilot study. Project teams met 14 times (approximately once a month) and spent 1.5 hours per meeting. Some projects did not measure the impact, others did not intend to have a specific impact, and still others measured but did not achieve the planned impact. DISCUSSION Patients and employees may be benefitting from improvement projects, but organizations may not be leveraging these improvements to reduce cost of delivery or increase market share. Considerable variation in the projects' impact raises the question of the need to improve the improvement methods. Generalization from this study should be made with caution, as data were based on a self-selected convenience sample of organizations. Furthermore, respondents did not complete all items, and missing information may affect the conclusions. The data on current improvement practices that are provided in this study can serve as baseline data against which rapid improvement efforts can be judged.

Abstract
Two data elements are needed for constructing a risk-adjusted X-bar chart. They are a continuous observed outcome collected over time across a sample of patients, and an expected outcome for each patient. The authors selected blood glucose levels to reflect diabetes control. They then reviewed data showing blood glucose levels of 60 Type 2 diabetes patients in a family practice clinic of five providers. The data covered a period of 21 consecutive months. They present the data relating to two of the providers using this set of data to demonstrate how to create a risk-adjusted X-bar control chart.

Abstract
This article proposes the use of the continuous improvement evaluation (CIE), a framework for multisite demonstration or evaluation studies. This framework is designed for studying intervention programs that change during the evaluation. The development of family drug courts is provided as an example. CIE relies on outcome data collected over time and benchmarked across similar cases in comparison sites; thus, this study was designed to collect data on effectiveness of intervention programs at multiple sites and over time. A weight is calculated for similarity of any two cases based on features they share. In statistical process control charts, these weights are used to compare outcomes at the site against the average of similar cases in comparison groups. Once data are benchmarked, program staff meet to discuss process changes that have led to improvements in outcomes. To ensure that intervention programs have access to evaluation reports on demand, information technology is used to collect, clean, and pool data. Computers generate study reports, and evaluators review reports after release to clients. Statistical tools can be used to evaluate changing programs. Traditional evaluators may be concerned about some threats to validity associated with CIE. The article concludes with a discussion of typical threats to validity and how these threats are addressed in the CIE framework.

Abstract
It is widely believed that better technology means better business: now that consumers and patients have direct access to computers and information services, the cost of care should decrease and services improve. Yet even with the advent of computer technology and the phenomenal growth of the Internet, costs have increased and quality problems have persisted. Far more important than the technology, then, is how business is conducted and systems are organized. Despite overwhelming evidence that computer services can significantly reduce the costs of care, healthcare organizations have not adopted the changes, or have tried and failed. This article explores what it will take to succeed. We propose a list of necessary nontechnical changes. Patient expectations will change the nature of care; clinicians' roles and training, the gatekeeper profession, healthcare financing and bundling of services, and capital costs will all change. In the end, management innovations make the difference between the success and failure of new technology. Technology is important, but it is not enough. Without new practices, we can buy the technology but will fail to effectively use it. Unless management modifies the very nature of its business, technology's promise to the healthcare industry will go unfulfilled.

Abstract
BACKGROUND Continuous quality improvement (CQI) thinking and tools have broad applicability to improving people's lives--in continuous self-improvement (CSI). Examples include weight loss, weight gain, increasing exercise time, and improving relationship with spouse. In addition, change agents, who support and facilitate organizational efforts, can use CSI to help employees understand steps in CQI. A STEP-BY-STEP APPROACH: Team members should be involved in both the definition of the problem and the search for the solution. How do everyday processes and routines affect the habit that needs to change? What are the precursors of the event? Clients list possible solutions, prioritize them, and pilot test the items selected. One needs to change the daily routines until the desired behavior is accomplished habitually and with little external decision. DISCUSSION CSI is successful because of its emphasis on habits embedded in personal processes. CSI organizes support from process owners, buddies, and coaches, and encourages regular measurement, multiple small improvement cycles, and public reporting.

Abstract
The Internet provides new opportunities to information-based industries such as universities. If a vast majority of potential customers of our programs have access to the Internet, then it is conceivable that many universities will begin teaching Internet courses and that such courses could, in many cases, replace or at least augment existing face-to-face classroom activities. This paper is an account of one such course at Cleveland State University and the type of policy issues raised by the course at this institution.

Abstract
Policy makers and hospital managers often use severity adjustments as a control for patient mix differences when evaluating outcomes of care. Unfortunately, few indices are carefully examined and therefore the evaluations based on these methods of severity adjustment are suspect. This paper examines the accuracy of three indices for measuring the severity of illness of AIDS patients. We examine the Diagnosis-Based Severity Index (DBSI), a modified version of DBSI referred to as MDBSI and the Composite Laboratory Index (CLI) in predicting survival of AIDS patients at one medical centre. We analysed the correlation between indices and months of survival. We also examined the percentage of variance in survival months explained by each index separately and together. Finally, we used survival analysis to examine whether DBSI classifies patients in groups with distinct patterns of survival. Only patients who had died were included in the analysis so that information on the patients' full course of illness was available. Of the 91 patients abstracted, 81 cases had date of AIDS, date of death, and the CLI. These 81 cases were the focus of the analysis. Both CLI and DBSI were predictive of months of survival but were not correlated to each other. Predictions of months of survival were improved if both indices were used together rather than separately. Survival analysis confirmed that patients classified by DBSI had distinctly different survival patterns. Each index measures different aspects of the severity of the patient's condition and when possible both indices should be used together. When laboratory data are not available, e.g. in Medicaid administrative files, the use of DBSI may be reasonable.

Abstract
The Schools of Medicine and Nursing at Case Western Reserve University and the Program in Health Administration at Cleveland State University have created an interdisciplinary course in continuous improvement that emphasizes learning through experience, accommodates a large number of students, and has created new partnerships with Cleveland area health care organizations. An approach that respects these partners as customers and refines the relationships with serial tests of change (e.g., PDSA) has contributed significantly to this program's success.

Abstract
BACKGROUND Suggestions, most of which are supported by empirical studies, are provided on how total quality management (TQM) teams can be used to bring about faster organizationwide improvements. SUGGESTIONS Ideas are offered on how to identify the right problem, have rapid meetings, plan rapidly, collect data rapidly, and make rapid whole-system changes. Suggestions for identifying the right problem include (1) postpone benchmarking when problems are obvious, (2) define the problem in terms of customer experience so as not to blame employees nor embed a solution in the problem statement, (3) communicate with the rest of the organization from the start, (4) state the problem from different perspectives, and (5) break large problems into smaller units. Suggestions for having rapid meetings include (1) choose a nonparticipating facilitator to expedite meetings, (2) meet with each team member before the team meeting, (3) postpone evaluation of ideas, and (4) rethink conclusions of a meeting before acting on them. Suggestions for rapid planning include reducing time spent on flowcharting by focusing on the future, not the present. Suggestions for rapid data collection include (1) sample patients for surveys, (2) rely on numerical estimates by process owners, and (3) plan for rapid data collection. Suggestions for rapid organizationwide implementation include (1) change membership on cross-functional teams, (2) get outside perspectives, (3) use unfolding storyboards, and (4) go beyond self-interest to motivate lasting change in the organization. CONCLUSIONS Additional empirical investigations of time saved as a consequence of the strategies provided are needed. If organizations solve their problems rapidly, fewer unresolved problems may remain.

Abstract
This paper describes our experience using telephone conference calls to conduct support groups for chemically-dependent women. Forty-seven women agreed to participate in regular, weekly support groups that were conducted by two chemical dependency counselors. Counselors attempted to conduct 59 support groups via a telephone conferencing system. Our data indicated that attendance at these sessions was poor. Seventeen sessions had no participants. No group sessions were attended by 4 or more women, and only 3 sessions (7.1%) included 3 participants. Very few clients made regular use of the support groups. Only 4 clients (8.5%) participated in more than 3 group sessions. Our findings suggest that teleconferencing may not be the most effective method for providing support services to chemically-dependent women.

Abstract
OBJECTIVES The authors analyzed the impact of home health education by studying the impact of a computer service called Community Health Rap. When patients call this service, the computer records their questions and alerts an expert who records a response. Subsequently, the computer alerts the patient that the question has been addressed. METHODS Subjects included a group of 82 pregnant women who had used cocaine during or 1 month before pregnancy (as reported by the woman) and a group of residents of zip code areas with the lowest income in Cleveland. From the drug-using pregnant women, we collected data regarding satisfaction with Community Health Rap, usage of Community Health Rap per month, self-reported health status (using the General Health Survey), and the extent of drug use (using the Addiction Severity Index). Trained coders also classified the nature of questions posed to the Community Health Rap by either the pregnant women who abuse drugs or the members of target households. Among the pregnant women who abuse drugs, we compared the differences between those who used the service and those who did not. To control for baseline differences between the two groups, analysis of co-variance was used with exit values as the dependent variables, the baseline values as the co-variates, and participation in the Community Health Rap as the independent variable. RESULTS Almost half (45%) of poor, undereducated subjects who lived in inner urban areas used the computer service. Content analysis of Community Health Rap messages revealed that subjects had many questions that were of a social nature (regarding sex, relationships, etc), in addition to medical questions. Analysis showed that poor health status, more frequent drug use, lower education, and age did not affect regular use of Community Health Rap service. No health outcomes or utilization of treatment were associated with regular use of Community Health Rap. One exception, however, was that regular users of Community Health Rap reported slower improvement of their pain than those who did not use Community Health Rap. CONCLUSIONS These data suggest that expansion of information services to households will not leave the poor and the undereducated population groups "behind." They will use computer services, though such services may not have an impact on their health status or cost of care.

Abstract
This article (1) describes a number of computer services provided to patients' homes, (2) summarizes four evaluation studies reported in this supplement, and (3) suggests direction for future research. The studies reviewed in this article suggest that computer services have little impact on patients' health status but a significant impact on use of services. Some computer services (eg, reminders) increase client visits and other services (eg, voice bulletin board) reduce clinic visits. The article suggests that a paradigm for conducting research on impact of home computer services on care of patients is missing and should be developed.
