Oral Squamous Cell Carcinoma: Focus on Biomarkers for Screening.

Oral cancer is a malignant neoplasia that can originate in the oral cavity or lips. It is a serious global health problem and one of the ten most common cancers worldwide. Over the years, changes in the trends of the oral cavity and oropharyngeal cancers have been observed. The management of oral cancer is complicated due to the functional and cosmetic consequences of treating malignancies at these anatomical locations. The tumor and its treatment can affect a variety of functional activities, including smell, sight, speaking, respiration, taste, jaw function, and mastication, either temporarily or permanently. Based on the importance of this tumor, screening oral cancer for early detection and finding the best biomarkers for diagnosis is a crucial concern. In this review of literature, the etiology, risk factors, treatment, and diagnosis of oral cancer will be reviewed with a focus on the most important biomarkers.

Harnessing the therapeutic potential of mesenchymal stem/stromal cell-derived extracellular vesicles as a novel cell-free therapy for animal models of multiple sclerosis.

Multiple sclerosis (MS) is a chronic, neuroinflammatory, and demyelinating disease of the central nervous system (CNS). Current treatments offer only limited relief from symptoms, and there is no cure. Mesenchymal stem/stromal cells (MSCs) have demonstrated therapeutic potential for MS. However, their clinical application faces challenges, including immune rejection and the potential for tumor formation. Recent studies suggest that MSCs exert their effects through extracellular vesicles (EVs) released from the cells, rather than direct cellular engraftment or differentiation. This discovery has sparked interest in the potential of MSC-derived EVs as a cell-free therapy for MS. This review explores the existing literature on the effects of MSC-EVs in animal models of MS. Administration of MSC-EVs from various tissue sources, such as bone marrow, adipose tissue, and umbilical cord, was found to reduce clinical scores and slow down disease progression in experimental autoimmune encephalomyelitis (EAE), the primary mouse model of MS. The mechanisms involved immunomodulation through effects on T cells, cytokines, CNS inflammation, and demyelination. Although the impact on CNS repair markers remained unclear, MSC-EVs exhibited the potential to modulate neuroinflammation and suppress harmful immune responses in EAE. Further studies are still required, but MSC-EVs demonstrate promising therapeutic effects for MS and warrant further exploration as a novel treatment approach.

The effect of SARS-CoV-2 on the development of Parkinson's disease: the role of α-synuclein.

The current coronavirus disease 2019 (COVID-19) can lead to various neurological complications in infected people. These neurological effects include problems in both central nervous system (CNS) and peripheral nervous system (PNS). Hyposmia, a PNS symptom of COVID-19, frequently manifests in the early stages of Parkinson's disease (PD) and serves as an early warning sign of the condition. In addition, the olfactory system is recognized as an early site for the onset of α-synuclein pathology, the pathological hallmark of PD. PD is characterized by accumulation and aggregation of misfolded α-synuclein (α-Syn) into Lewy bodies and Lewy neurites, resulting in the degeneration of dopaminergic neurons in substantia nigra pars compacta (SNpc). Previous research has also shown the involvement of α-Syn in the innate immune response following viral infections. Consequently, the potential link between viral infections and development of PD has gained attention in recent years. However, it's still too early to definitively conclude whether COVID-19 can cause Parkinsonism. Nevertheless, we can explore the likelihood of this connection by examining past studies and possible mechanisms to better understand how COVID-19 might potentially lead to PD following the infection. Based on the various pieces of evidence discussed in this review, we can infer that SARS-CoV-2 promotes the aggregation of α-Syn and, ultimately, leads to PD through at least two mechanisms: the stable binding of the S1 protein to proteins prone to aggregation like α-Syn, and the upregulation of α-Syn as part of the immune response to the infection.

Effect of Disease-Modifying Therapies on COVID-19 Vaccination Efficacy in Multiple Sclerosis Patients: A Comprehensive Review.

According to current knowledge, the etiopathogenesis of multiple sclerosis (MS) is complex, involving genetic background as well as several environmental factors that result in dysimmunity in the central nervous system (CNS). MS is an immune-mediated, inflammatory neurological disease affecting the CNS. As part of its attack on the axons of the CNS, MS witnesses varying degrees of myelin and axonal loss. A total of about 20 disease-modifying therapies (DMTs) are available today that, both in clinical trials and in real-world studies, reduce disease activity, such as relapses, magnetic resonance imaging lesions, and disability accumulation. Currently, the world is facing an outbreak of the new coronavirus disease 2019 (COVID-19), which originated in Wuhan, Hubei Province, China, in December 2019 and spread rapidly around the globe. Viral infections play an important role in triggering and maintaining neuroinflammation through direct and indirect mechanisms. There is an old association between MS and viral infections. In the context of MS-related chronic inflammatory damage within the CNS, there has been concern regarding COVID-19 worsening neurological damage. A high rate of disability and increased susceptibility to infection have made MS patients particularly vulnerable. In addition, DMTs have been a concern during the pandemic since many DMTs have immunosuppressive properties. In this article, we discuss the impact of DMTs on COVID-19 risks and the effect of DMTs on COVID-19 vaccination efficacy and outcome in MS patients.

The mTOR Signaling Pathway Interacts with the ER Stress Response and the Unfolded Protein Response in Cancer.

The mTOR complex 1 (mTORC1) coordinates several important environmental and intracellular cues to control a variety of biological processes, such as cell growth, survival, autophagy, and metabolism, in response to energy levels, growth signals, and nutrients. The endoplasmic reticulum (ER) is a crucial intracellular organelle that is essential for numerous cellular functions, including the synthesis, folding, and modification of newly synthesized proteins, stress responsiveness, and maintainence of cellular homeostasis. mTOR-mediated upregulation of protein synthesis induces the accumulation of misfolded or unfolded proteins in the ER lumen, which induces ER stress, leading to activation of the unfolded protein response (UPR) pathway. Reciprocally, ER stress regulates the PI3K/AKT/mTOR signaling pathway. Therefore, under pathologic conditions, the cross-talk between the mTOR and UPR signaling pathways during cellular stress can critically affect cancer cell fate and may be involved in the pathogenesis and therapeutic outcome of cancer. Here, we discuss accumulating evidence showing the mechanism of action, interconnections, and molecular links between mTOR signaling and ER stress in tumorigenesis and highlights potential therapeutic implications for numerous cancers.

Quercetin potentiates the anti-osteoporotic effects of alendronate through modulation of autophagy and apoptosis mechanisms in ovariectomy-induced bone loss rat model.

BACKGROUND: Osteoporosis is a bone disease leading to bone fracture and affects 200 million women worldwide. Autophagy and apoptosis are two fundamental mechanisms that are involved in the development of osteoporosis. In this study we aim to investigate the combined effects of quercetin and alendronate on the markers of osteoporosis, autophagy, and apoptosis in the bone of ovariectomized rats. METHODS AND RESULTS: Fifty adult female Sprague-Dawley rats were ovariectomized and treated with alendronate alone (5 µg/kg/day) or alendronate (5 µg/kg/day) in combination with quercetin (15 mg/kg/day) for 12 weeks. Then, ELISA, stereological tests, Real-time PCR analysis, and immunofluorescence assay were used to measure the markers of osteoporosis, autophagy, and apoptosis in the serum and tibia of rats. The serum osteocalcin was significantly decreased in ovariectomized rats that received quercetin and alendronate compared with alendronate only. Stereological data showed that except for osteoclasts, the total trabecular volume, bone weight, bone volume, osteocyte, and osteoblast numbers were increased in an ovariectomized group that was treated with quercetin and alendronate compared with alendronate alone. Except for Bcl2, the autophagy markers (Beclin-1 and LC3B) and Caspase-3 were significantly downregulated in ovariectomized rats that received quercetin and alendronate compared with those treated with alendronate alone. CONCLUSION: Our results show that quercetin enhances the anti-osteoporotic effects of alendronate, possibly through the regulation of autophagy and apoptosis mechanisms. These findings suggest that the combination of quercetin and alendronate could be a useful therapeutic strategy in the treatment of osteoporosis in postmenopausal women.

Effect of General Practitioner Training in a Collaborative Child Mental Health Care Program on Children's Mental Health Outcomes in a Low-Resource Setting: A Cluster Randomized Trial.

Importance: Integrated care for children is rarely studied, especially in low- and middle-income countries, where generalists often provide mental health care. Objectives: To explore the effect of adding a child and youth component to an existing adult collaborative care program on mental health outcomes and receipt of care. Design, Setting, and Participants: This cluster randomized trial was conducted within an adult collaborative care program in Tehran, Iran. General practitioners (GPs), their 5- to 15-year-old patients, and patients' parents were included. Children and youths coming for routine medical visits who scored greater than the cutoff on the Strengths and Difficulties Questionnaire (SDQ) were followed up for 6 months. The study was conducted from May 2018 to October 2019, and analysis was conducted from March 2020 to August 2021. Interventions: GPs were randomized to either a 2.5-day training on managing common child mental health problems (intervention) or refresher training on identification and referral (control). Main Outcomes and Measures: Primary outcome was change in SDQ total problems score; secondary outcomes included discussion of psychosocial issues by the GPs and receipt of mental health care during the follow-up period. Results: Overall, 49 GPs cared for 389 children who scored greater than the cutoff on the SDQ (216 children in intervention group, 173 in control group). Patients' mean (SD) age was 8.9 (2.9) years (range, 5 to 15 years), and 182 (47%) were female patients. At 6 months, children in the intervention group had greater odds of receiving mental health care during the study (odds ratio [OR], 3.0; 95% CI, 1.1 to 7.7), parents were more likely to report that intervention GPs had discussed parent (OR, 2.1; 95% Cl, 1.1 to 3.8) and child (OR, 2.0; 95% Cl, 0.9 to 4.8) psychosocial issues, and intervention GPs were more likely to say they had provided counseling (OR, 1.8; 95% Cl, 1.02 to 3.3). However, there was no greater improvement in SDQ scores among children seen by intervention vs control GPs. Adjusted for clustering within GP, the variables used for balanced allocation (practice size, practice ownership, and study wave), and the other variables associated with change in SDQ scores over time, there was not a significant time-treatment interaction at either the 3- or 6-month follow-up points (linear combination of coefficients for intervention, 0.57 [95% CI, -1.07 to 2.22] and -0.08 [95%CI, -1.76 to 1.56], respectively). In a subgroup of GPs with practices composed of 50% or more children, children seen by intervention GPs improved to a significantly greater extent (-3.6 points; 95% CI, -6.7 to -0.46 points; effect size d = 0.66; 95% CI, 0.30 to 1.01) compared with those seen by control GPs. Conclusions and Relevance: In this cluster randomized trial, GP training on managing common child mental health problems did not demonstrate greater improvement in child SDQ scores. Child mental health training for GPs in collaborative care can improve children's access to mental health care, but prior experience working with children and their families may be required for GPs to use a brief training in a way that improves child outcomes.

miRNAs as the important regulators of myasthenia gravis: involvement of major cytokines and immune cells.

Myasthenia gravis (MG) is a type of muscle paralysis created by immune responses against acetylcholine receptor proteins in neuromuscular synapses. This disease is characterized by muscle weakness, especially ocular weakness symptoms that could be ptosis (fall of the upper eyelid) or diplopia (double vision of a single object). Some patients also identified with speech and swallowing problems. The main goals of MG therapeutic approaches are to achieve remission, reduce symptoms, and improve life quality. Recently, other studies have revealed the potential role of various microRNAs (miRNAs) in the development of MG through different mechanisms and have proposed these molecules as effective biomarkers for the treatment of MG. This review was aimed at providing an overview of the critical regulatory roles of various miRNAs in the pathogenesis of this autoimmune disease focusing on human MG studies and the interaction between different miRNAs with important cytokines and immune cells during the development of this autoimmune disease.

The role of miRNAs from mesenchymal stem/stromal cells-derived extracellular vesicles in neurological disorders.

Mesenchymal stem/stromal cells (MSCs) are multipotent cells with immunomodulatory effects that have been attempted as a possible treatment for neurologic disorders. Since currently available drugs for neurologic disorders are limited, special attention has been paid to MSCs. With the ability to differentiate into neural cells, it has been shown that MSCs exert their effects in a paracrine manner by producing extracellular vesicles (EVs). Extracellular vesicles are small vesicles with a size of 30-1000 nm that are released by cells, such as MSCs, T cells, B cells, etc. EVs contain various molecules, including proteins, lipids, mRNAs, and microRNAs (miRNAs). In recent years, the administration of EVs in models of neurological disorders has been shown to improve neurological dysfunctions. miRNAs from MSC-EVs as one of the important mediators which regulate various genes and reduce neuropathological change have been identified in different neurological disorders. Here, we review the effects of EVs miRNAs from MSCs on different neurological disorders and their potential applications.

Crocus sativus (saffron) in the treatment of female sexual dysfunction: a three-center, double-blind, randomized, and placebo-controlled clinical trial.

Objective: One of the traditional aphrodisiacs used in various cultures is Crocus sativus, commonly called saffron. Previous studies have pointed to the possible applicability of saffron for sexual dysfunction in both men and women. This study investigates the effects of saffron capsules on female sexual dysfunction. Materials and Methods: This study was a parallel-group, double-blind, randomized, placebo-controlled clinical trial. Participants, who were married women between 18 and 55 years of age suffering from severe sexual dysfunction, were randomized to receive either 15 mg Crocus sativus capsules twice daily or placebo. The treatment continued for 6 weeks, and patients were evaluated every 2 weeks. The primary outcome was the change in the female sexual function index score. Other outcomes included the female sexual function index sub-domains. Results: Seventy -four patients were equally randomized to each group, and 34 in each group completed the trial. Participants in both groups experienced improved total scores at each visit. However, a repeated-measures ANOVA revealed that time treatment differed between groups in favor of the saffron group (p=0.050). During the 6th week follow-up, the saffron group had a 62% score improvement from baseline. Desire, lubrication, and satisfaction were female sexual function index domains in which saffron demonstrated superiority over placebo. The adverse event profile was similar for the groups, and no participant discontinued treatment. Conclusion: Findings of this study suggest that saffron might be a safe and effective option to ameliorate female sexual dysfunction. Further robust research is warranted.

Therapeutic effects of human adipose mesenchymal stem cells and their paracrine agents on sodium iodate induced retinal degeneration in rats.

AIMS: The degeneration of retinal neurons which occurs in many neurodegenerative diseases of retina such as retinitis pigmentosa and aged-related macular degeneration, is a progressive phenomenon and leads to permanent visual disability. Aside from their economic and social impact, those who suffer from these diseases have a poor quality of life due to the lack of cures. Researchers have turned to stem cell therapies as a potential solution to this global health crisis. Mesenchymal stem cells (MSCs) and their paracrine agents such as conditioned medium (CM) and exosomes (Exo) have been applied to treat different retinal disorders. This study compared the therapeutic effects of human adipose mesenchymal stem cells (hADSCs) and their secretome on an in vivo model of sodium iodate retinal neurodegeneration. MAIN METHODS: We analyzed the expression of retinal cells' specific mRNAs by RT-PCR and proteins by immunostaining as well as performing visual cliff avoidance test as a functional evaluation technique. There were four therapeutic groups in this study: hADSC, hADSC-CM, hADSC-Exo and hADSC-Exo + CM. KEY FINDINGS: Although all groups showed different therapeutic effects on various retinal cells, the results of hADSC-CM were most striking, especially in terms of photoreceptor regeneration and retinal function. SIGNIFICANCE: The findings of present study demonstrated the different effects of MSC-based therapies on various retinal cells which could be helpful in designing more precise treatments that suit to each neurodegenerative disease mechanism and the cells involved. It also suggests that CM might be a better choice due to its multifactorial characteristic.

The Role of Immune Regulatory Molecules in COVID-19.

As the fifth pandemic in the 21st century, coronavirus 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become the most prominent global concern in the last 2 years. Variable manifestations characterize SARS-CoV-2 infection. Despite the design and production of effective vaccines and their considerable effect on reducing the COVID-19 prevalence and mortality rate, no definitive cure for the disease has yet been found. Mutations may also affect the effectiveness of vaccines. The host immune response to the pathogen has a critical role in the course of the disease. Positive and negative signals often balance the immune system. Immune regulatory molecules, also known as immune checkpoint receptors, balance the immune responses. These molecules mainly have inhibitory functions and prevent hyperactivation of immune cells or trigger adverse signaling pathways. For a decade, the immune checkpoint blockade, as a therapeutic target for cancer immunotherapy, has been utilized. Some of the inhibitory receptors are recognized as exhaustion markers on T cells. The signaling pathway of these markers restricts the function of T cells against viral infection. Dysregulation of T cells was observed in SARS-CoV-2 infection and can modify proliferation, differentiation, cytokine production, and type of response. The pivotal role of immune inhibitory receptors in the function of acquired, cell-mediated, immune defense T cells makes them a fascinating subject to study. This review article summarized recent findings on immune regulatory molecules and their role in SARS-CoV-2 infection, hoping to find a way to design novel treatments.

PI3K/Akt/mTOR pathway: a potential target for anti-SARS-CoV-2 therapy.

Coronavirus disease 2019 (COVID-19) is a viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A single-stranded RNA virus from a ß-Coronaviridae family causes acute clinical manifestations. Its high death rate and severe clinical symptoms have turned it into the most significant challenge worldwide. Up until now, several effective COVID-19 vaccines have been designed and marketed, but our data on specialized therapeutic drugs for the treatment of COVID-19 is still limited. In order to synthesis virus particles, SARS-CoV-2 uses host metabolic pathways such as phosphoinositide3-kinase (PI3K)/protein kinase B (PKB, also known as AKT)/mammalian target of rapamycin (mTOR). mTOR is involved in multiple biological processes. Over-activation of the mTOR pathway improves viral replication, which makes it a possible target in COVID-19 therapy. Clinical data shows the hyperactivation of the mTOR pathway in lung tissues during respiratory viral infections. However, the exact impact of mTOR pathway inhibitors on the COVID-19 severity and death rate is yet to be thoroughly investigated. There are several mTOR pathway inhibitors. Rapamycin is the most famous inhibitor of mTORC1 among all. Studies on other respiratory viruses suggest that the therapeutic inhibitors of the mTOR pathway, especially rapamycin, can be a potential approach to anti-SARS-CoV-2 therapy. Using therapeutic methods that inhibit harmful immune responses can open a new chapter in treating severe COVID-19 disease. We highlighted the potential contribution of PI3K/Akt/mTOR inhibitors in the treatment of COVID-19.

Mesenchymal Stem Cells as A New Approach for the Treatment of Multiple Sclerosis:A Literature Review :.

Multiple sclerosis (MS) is a high-prevalence autoimmune and neurodegenerative disease that affects young adults. An ideal treatment for MS should have two characteristics. First, its immunosuppression and immunomodulation effects reduce the abnormal immune response, and second, it improves repair by enhancing intrinsic repair processes or even cell replacement. Most available therapies have the first characteristic. Recent studies have proposed mesenchymal stem cells (MSCs) as a new therapeutic candidate for MS. Different clinical trials and animal models of MS have shown the therapeutic effect of MSCs. In the current study, we reviewed the therapeutic effects of MSCs in the animal model and patients with MS.

Children and adolescents' mental health in Iran's primary care: Perspectives of general practitioners, school staff and help seekers.

BACKGROUND: Iran has well-established networks for primary care staffed by general practitioners who provide services to patients across the lifespan. Iran recently established collaborative care networks to build general practitioners' capacity to provide adult mental health services. In an NIH-funded study, we are designing and evaluating a training program for general practitioners (GPs) to extend this collaboration to include services for children and adolescents. In the formative phase of this project, we conducted a qualitative study to obtain information relevant to the design of the training program. METHODS: We conducted semi-structured individual interviews with 28 stakeholders; including 15 GPs working in a collaborative care network, 6 parents and 4 adolescents who had received child mental health care from a GP, and 3 policymakers. We also held a focus group discussion with 8 school teachers and counselors. All interviews were transcribed during the interviews' sessions and then were thematically analyzed. RESULTS: GPs reported seeing a range of child emotional and behavioral problems but felt the need for additional training in diagnosis and management, especially in skills for interviewing and communicating with children. GPs also expressed the need to understand legal issues involved in treating children, including cases of possible child abuse. School staff agreed that GPs could help with children's educational and emotional problems but also believed GPs would need extra training. Parents indicated a preference for GPs over psychiatrists (as did adolescents) as a source of mental health care, and for psychological over pharmacological interventions. Adolescents expressed a preference not to speak about private issues in the presence of their parents, and expressed concern that the GPs did not respect their preference. They also desired a more active role during visits. CONCLUSIONS: Before expanding the scope of practice of Iranian GPs to provide management of common emotional and behavioral problems in children and adolescents, the concerns and specific needs of these practitioners need to be addressed. Parents and youth in the study expressed a preference for mental health care from a GP rather than a specialist. However, they also commented on the need for restructuring the current GP visits to facilitate youth participation. These findings provide directions for expanding the scope of practice of adult collaborative care networks to meet the mental health care needs of children and adolescents more expeditiously and effectively.

Species diversity and molecular analysis of opportunistic Mycobacterium, Nocardia and Rhodococcus isolated from the hospital environment in a developing country, a potential resources for nosocomial infection.

BACKGROUND: Hospital environmental resources have a significant role in cross-transmission of opportunistic pathogens such as actinomycetes species to the patients. Actinomycetes have a remarkable capability to survive in adverse and harsh conditions of hospital environments; therefore, they are a threat to the health of patients. Due to this issue, we aimed to determine the frequency and diversity of actinomycetes species in hospital soil, water and dust by using a combination of conventional and molecular methods including the phenotypic and biochemical tests for preliminary identification and the PCR amplification of the specific region of the 16S rRNA, hsp65 gene and sequence analyses of 16S rRNA for the genus and species identification. RESULTS: A total of 50 (35.2%) actinomycetes isolates from 7 genera were isolated from 142 hospital environmental samples. The three most prevalent species were M. setense 10%, R. erythropolis and M. fortuitum 8% followed by N.cyriacigeorgica and M. gordonae 6%, M. chelonae, M. abscessus, M. lentiflavum, M. mucogenicum, N. asteroides, N. farcinica, R. equi and L. shinushuensis 4% and the single isolates of M. conceptionense, M. septicum, N. rhamnosophilia, N. bravicatena, M. flavescens, M. arupense, M. doricum, M. frederiksbergense, S. heliomycini, S. albus, S. albogriseolus, R. facians, D. maris, G. terae and A. globiformis. CONCLUSIONS: In conclusion we showed that the hospital environment is a potential reservoir for a broad range of actinomycetes species, due to the remarkable survival capability of these microorganisms in adverse hospital environment, carrying a threat to the health of patients.

Vitamin E and ginseng supplementation to enhance female sexual function: a randomized, double-blind, placebo-controlled, clinical trial.

Female sexual disorders (FSD) are a spectrum of disorders common among women, especially in their middle age, which can reduce the female quality of life substantially. We aimed to evaluate the effects of a combined vitamin E and ginseng supplement on amelioration of female sexual dysfunction. In a 6-week, double-blind, randomized, placebo-controlled clinical trial, participants, suffering from sexual dysfunction based on the female sexual function index (FSFI) questionnaire, were randomly allocated to receive the supplement (100 IU vitamin E, 67 mg Korean ginseng, and 40 mg Siberian ginseng) or placebo daily. The primary outcome in our trial was the change in the FSFI total score. Sixty-nine participants were enrolled, but only 31 in each group completed the trial. Changes in the FSFI total score and its domain scores were significant during the trial course within each group. However, the supplement only ameliorated desire and satisfaction domains superior to the placebo. In case of the total score and other domains, the changes were insignificantly different between the treatment groups. Although our study could not find additional benefits for the vitamin E and ginseng supplement over placebo in enhancing sexual function overall, the supplement worked better in enhancing sexual desire and satisfaction.

The immunoregulatory and neuroprotective effects of human adipose derived stem cells overexpressing IL-11 and IL-13 in the experimental autoimmune encephalomyelitis mice.

Multiple sclerosis (MS) is an inflammatory demyelination disease in the central nervous system (CNS) characterized by incomplete endogenous remyelination in the chronic phase. A shift of the balance between pro and anti-inflammatory cytokines is one of the important markers in the pathogenesis of MS. This study aimed to evaluate the effects of human adipose derived stem cells (hADSCs) overexpressing interleukin 11 and interleukin 13 (IL-11, 13-hADSCs) on the experimental autoimmune encephalomyelitis (EAE), an animal model of MS.12 days after immunization of C57Bl/6 female mice with MOG35-55 and initial clinical symptoms appearance, the IL-11, 13-hADSCs were injected via the tail vein into the EAE mice. Then, the mice were sacrificed at 30 days post-immunization (DPI) and the spinal cords of experimental groups were extracted for histopathological and real-time RT-PCR studies.The results indicated that the clinical scores and mononuclear cells infiltration into the spinal cords of EAE mice were significantly reduced in mice treated with IL-11, 13-hADSCs. Likewise, the remyelination and oligodendrogenesis were significantly enhanced in the mentioned treatment group. Real-time results demonstrated that pro/anti-inflammatory cytokine genes expression was reversed in IL-11, 13-hADSCs treatment group in comparison to the untreated EAE group.Expression of IL-11 as a neurotrophic cytokine and IL-13 as an anti-inflammatory cytokine by hADSCs could increase the immunomodulatory and neuroprotective effects of hADSCs and be a powerful candidate in stem cell therapy for future treatment of MS.

Laboratory Findings of COVID-19 Infection are Conflicting in Different Age Groups and Pregnant Women: A Literature Review.

Coronavirus disease 2019 (COVID-19), a new type and rapidly spread viral pneumonia, is now producing an outbreak of pandemic proportions. The clinical features and laboratory results of different age groups are different due to the general susceptibility of the disease. The laboratory findings of COVID-19 in pregnant women are also conflicting. Para-clinical investigations including laboratory tests and radiologic findings play an important role in early diagnosis and treatment monitoring of COVID-19. The majority of previous reports on the COVID-19 laboratory results were based on data from the general population and limited information is available based on age difference and pregnancy status. This review aimed to describe the COVID-19 laboratory findings in neonates, children, adults, elderly and pregnant women altogether for the first time. The most attracting and reliable markers of COVID-19 in patients were: normal C-reactive protein (CRP) and very different and conflicting laboratory results regardless of clinical symptoms in neonates, normal or temporary elevated CRP, conflicting WBC count results and procalcitonin elevation in children, lymphopenia and elevated lactate dehydrogenase (LDH) in adult patients, lymphopenia and elevated CRP and LDH in the elderly people, leukocytosis and elevated neutrophil ratio in pregnant women.
