Abstract
Background and Aims: Portulaca oleracea (purslane) herb has renewed an interest in medicinal plants because its aerial parts usage generally does not elicit any side effects. In the present study, we aimed to evaluate the anti-diabetic effect of hydro-ethanolic extract of P. oleracea seeds in alloxan- induced diabetic rats.
Materials and Methods: In the test group, diabetic rats received hydroethanolic extract at doses of 50, 100 and 200 mg/kg, intraperitoneally for 14 days while in the control group, they received just saline vehicle. Then, biochemical analysis was performed to evaluate serum profiles in diabetic treated rats. After that, liver sections were prepared for histopathological analysis.
Results: In comparison to the control group, the serum profiles of the test group exhibited significant changes. In the control diabetic group, the serum levels of glucose, cholesterol, triglyceride, low-density lipoprotein, urea and uric acid were 494, 122, 220, 163, 492 and 94 mg/dL and aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase were 3215, 3394 and 1527 UI/l reduced respectively to 165, 18, 120, 63, 36 and 52 mg/dL and 1219, 1229 and 1717 UI/l in the test groups. Also, the administration of the purslane extract significantly increased high-density lipoproteins and total protein levels and attenuated hispathological damage in liver tissue in alloxan- induced diabetic rats.
Conclusions: The present data indicated that hydro-ethanolic extract of P. oleracea seeds has anti-diabetic effect in diabetic animals. So, this plant should be considered in future therapeutic researches.

Abstract
Background and Aims: The antioxidant and anti-inflammatory effects of carvacrol were reported. The aim of the current study was an investigation the relaxant effects of carvacrol on acetylcholine-induced contraction in isolated rat's ileum.
Materials and Methods: In this study, the tissues separated from ileum were fixed on the organ bath containing Tyrode's solution. The amplitude of contractions has been recorded using isotonic transducer. Before and after subjecting the tissues with saline and different concentrations of carvacrol,the procedure was elicited by cumulative logarithmic concentrations of acetylcholine (Ach).
Results: Our results indicated that carvacrol at 10-2, 10-3 and 10-4, but not 10-5 M decreased acetylcholine (10-4 M)-induced contraction (10-2 M at p<0.001; 10-3 and 10-4 at p<0.05 vs. Ach+saline). The antispasmodic effect of carvacrol was examined and showed that in concentrations of 10-5, 10-4 and 10-3 M, but not 10-6 M, the contractive effect of acetylcholine10-3 M was prevented significantly. The concentrations of 1, 2 and 4 µM of verapamil were also tested and indicated that 4 µM of verapamil reduced contraction by 22.1±.5% (p<0.01 vs. saline). In samples treated with combined carvacrol (10-5 M) and verapamil (4 µM) contraction percentage was decreased by 35±14%, which was significantly different compared to the Ach+saline group as well as the single treated groups (p<0.01 and p<0.05, respectively).
Conclusions: According to our findings, due to the effect of carvacrol and verapamil, the relaxant mechanism of carvacrol may be mediated by Ca+2 release from the sarcoplasmic reticulum and the response of the contractile system.

Abstract
Cytomegalovirus (CMV) is a species of Herpesviridae showing no clinical symptoms in the earlier stage of infection in pregnant women. Nevertheless, it can be transmitted to the baby through saliva, body fluids, blood and cervical secretions. The aim of this study is a systematic review of the effects of CMV on abortion. Data were collected from Web of Science (ISI), PubMed, Scopus, Ovid, and EMBASE databases published by May 2018. The keywords used included abortion, current abortion, B19, Cytomegalovirus, spontaneous abortion, and placenta. The National Institutes of Health's Quality Assessment Tool was used for quality assessment. Fifteen papers from 1993 to 2018 were reviewed 11 of which were descriptive-analytic and the remaining 6 were case-control. In the case-control studies, the control group consisted of healthy pregnant women with no history of abortion. The case group comprised women who had experienced abortion and recurrent abortion. The maximum sample size included 779 and the minimum included 17 cases of abortion. The highest incidence of CMV infection in abortion was 100% reported by Saraswathy and 97% in the study of Tarokhian. The lowest was observed by Oliveira with 0.04% and by Kakru with 16%.The results of most studies indicate that CMV infection can lead to abortion by transfer through body fluids activation of the uterine inflammatory response and immune response, as well as transfer into embryonic tissues.

Abstract
Despite the various therapies available, the use of monoclonal antibodies is a highly specific approach that has only recently been of interest to researchers. The properties of antibodies have led to their use in the treatment of various diseases, including cancer, Alzheimer's disease, diabetes and multiple sclerosis (MS). MS, a chronic inflammatory disease, occurs commonly in young adults. The disease is one of the attractive options for monoclonal antibody therapy because it has no definitive drug for its treatment. Antibodies, by targeting different molecules, have different mechanisms to improve the disease. Treatment with monoclonal antibody has culminated in a clear divergence in paradigm and concentration in MS therapeutics. Application of monoclonal antibody in early inflammatory phases can inhibit or postpone the disability in MS subjects. Ocrelizumab and daclizumab are currently under investigation by late phase III trials, and some other monoclonal antibodies are in the early stages of clinical trials. Monoclonal antibodies are of special structural features (including chimeric, humanized, or fully humanized) as well as specific targets (such as stimulation of signal transduction by binding to receptors, blocking interactions, antibody-dependent cell cytotoxicity, complement-dependent cytotoxicity), thus providing various mechanisms of actions during MS therapy. In the present paper, we reviewed different monoclonal antibodies used in MS, their mechanism of action and theirs target molecules.

Abstract
Suitable alternatives are made for damaged or diseased organs and tissues in tissue engineering by combining cellular and molecular biology with materials and mechanical engineering. Fibrin is a critical blood component responsible for homeostasis, used extensively as a biopolymer scaffold in tissue engineering. This study summarizes the latest developments in organ and tissue regeneration using fibrin as a scaffold material. The combination of active peptides and growth factors through a heparin-bound delivery system improves fibrin function as a scaffold. Besides, the development of fibrin precursors as recombinant proteins solves multiple or single donor fibrin adhesives. Its composite allows biomolecules to be combined with fibrin and can significantly enhance fibrin efficacy in cartilage tissue engineering applications.

Abstract
Background and Aims: The current preliminary study aimed to assess the clinical symptoms of the 67 Iranian COVID-19 patients and investigate the possible beneficial effects of the naproxen compared to the standard therapeutic regimen.
Materials and Methods: We assessed 67 COVID-19 patients. All COVID-19 cases were confirmed by computed tomography (CT) and real time-polymerase chain reaction tests. We evaluated the clinical symptoms of the patients at the admission time. Also, a group of 28 patients received naproxen besides their standard treatment. Clinical presentations, radiographic features, white blood cells (WBC) in peripheral blood, hemoglobin, platelets, C-reactive protein, erythrocyte sedimentation rate, blood urea nitrogen, lactate dehydrogenase, Albumin, and Creatine Phosphokinase were evaluated.
Results: The patients' clinical symptoms show that cough (89.6%) was the most repeated signed at the admission time, followed by fever at 78.7%, fatigue at 70%, and myalgia at least 64.2%. Unilateral slight ground-glass opacity was the most abundant presentation by 64.1% in CT. The laboratory assessment in patients indicates that mean WBC was 6193 ± 3258 (x106 /L), and mean lymphocyte was 27.8 ± 12%. The survival rate and the hospitalization days for patients with or without the Naproxen regimen were not statistically significant.
Conclusion: The most common clinical symptoms in Iranian patients with COVID-19 at the admission time include cough, fever, fatigue, and myalgia. Based on the current study results, the survival rate and the hospitalization days for patients with or without Naproxen usage were not statistically significant. The laboratory parameters could not show any particular statistically significant differences.

Abstract
SARS-CoV-2 causes coronavirus disease 2019 (COVID-19) and is responsible for the recent pandemic in the world. It has been recently recognized as a challenge for public health and a significant cause of severe illness in all age groups. Young children and older people are susceptible to SARS-CoV-2 infection. However, children usually present mild symptoms compared to adult patients. The relationship between age, severity, and COVID-19 transmission is compared to determine whether there is any reasonable relationship between age and COVID-19. It should be mentioned that some risk factors may increase the probability of developing severe COVID-19 by advancing age, such as pathophysiological changes in the respiratory system, angiotensin-converting enzyme 2 expression in the nasopharynx, and smoking. Susceptibility to SARS-CoV-2 infection is independent of age, but the mortality rate of COVID-19 depends on age.

Abstract
Neutrophils are innate immune system phagocytes that play a central role in immunity defense. They are equipped with effective antimicrobial that is mainly stored in specialized granules. Considering that, it can also damage host tissue. Neutrophil deployment is heavily regulated through various strategies, including phagocytosis, reactive oxygen species, production degranulation, and the formation of neutrophil extracellular traps (NET). This review article will discuss its role in inflammatory, autoimmune diseases, and cancer and place it as a therapeutic target. It depicts that NET formation includes a suicide program morphologically different from other types of cell death, such as apoptosis and necrosis. Besides, NETs have unique DNA and antimicrobial peptide structures, and antimicrobial activity is among the functions of neutrophils as the first response to inflammation. So, it plays a pivotal role in the pathophysiology of various diseases, especially inflammatory and autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. As a result, it can be effective in the pathogenesis of many diseases, and its pathogenic role can be used as a therapeutic target.

Abstract
Background and Aims: In the absence of treatment for Severe Acute Respiratory Syndrome Coronavirus 2, there is an urgent need to find alternative methods to control the spread of coronavirus disease 2019 (COVID-19). This study was conducted to compare the effects of vitamin D3 and N-acetylcysteine (NAC) on clinical status indicators in patients with COVID-19 hospitalization in Abadan, Iran.
Materials and Methods: 100 hospitalized patients with COVID-19 infection participated in this study. Patients were randomly allocated to four groups: 3 intervention groups and 1 control group. All patients received standard treatment. In addition, the intervention-1 group received NAC tablets and vitamin D3 placebo ampoules. The intervention-2 group received NAC tablets and vitamin D3 ampoules. The intervention-3 group received vitamin D3 ampoules and NAC placebo tablets. The control group received vitamin D3 placebo ampoules and NAC placebo tablets. Symptoms of the disease and clinical status indicators were compared in groups in the baseline and on days 7, 14, 21, and 28, respectively.
Results: The trial comparison showed that the incidence of cough, dyspnea, and serum glutamic pyruvic transaminase in laboratory tests in the NAC-P1 group was lower than in the other three groups (p <0.005). Also, the results showed a significant difference in the length of hospitalization between the four groups. The length of hospitalization was decreased in the NAC-D3 group (p < 0.024).
Conclusion: Based on the results, vitamin D3 supplements and NAC can improve some outcomes in COVID-19 treatment; however, more randomized controlled trial studies are required in this field.
