As soon as the genetic sequence of SARS-CoV-2 was released, intense global activity around different vaccine platform technologies started. Among these platforms, the viral vectored chimpanzee adenovirus Oxford1 (ChAdOx1)-previously studied for various indications, including for the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) vaccine, and currently is adapted for the ChAdOx1 nCoV-19 (novel Coronavirus-19). Therefore, this systematic review aimed to investigate the potential of the ChAdOx1 platform for the development of a vaccine for SARS-CoV and MERS-CoV, the Lethal Human-Coronaviruses (Lh-CoVs). For this purpose, a highly sensitive literary search was conducted through electronic databases that reached 1,445 related articles, of which, eight articles were elected according to previous eligibility criteria. The gathering of the articles demonstrated that the previous approaches, referring to the ChAdox1 platform, have contributed to the development of vaccines against Lh-CoVs and, that thus far, ChAdOx1 (nCoV-19 and MERS) vaccines are safe and immunogenic. However, it is important to emphasize that further studies are needed to ensure the effectiveness of vaccines in humans. https://acta.tums.ac.ir/index.php/acta/article/view/8931 https://acta.tums.ac.ir/index.php/acta/article/download/8931/5769

The research was carried out using 75 infertile males and 75 males with proven fertility as controls. The anthropometrics (weight, height) were measured and body mass index (BMI) computed. Venous blood was collected from each participant, allowed to clot, and centrifuged to obtain the serum which was analysed for testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH) concentrations. Semen was collected by masturbation and analysed for sperm quality, seminal fructose concentration, and histone deacetylase (HDAC) activities. A non-significant difference (P>0.05) in weight, height, and BMI; a significant increase (P<0.05) in ejaculated volume, serum LH, FSH, seminal fructose concentrations and HDAC activities; and a decrease in sperm count, sperm motility, serum testosterone concentration was observed among subgroups of infertile men. A direct and significant correlation exists between seminal HDAC activities and fructose concentration. Also, an inverse non-significant correlation exists between HDAC activities and spermatozoa motility. Base on the result obtained from this study, it can be concluded that measuring seminal fructose and HDAC activities in addition to routine biochemical and biophysical parameters will assist in diagnostic work up in subgroups of male infertility. https://acta.tums.ac.ir/index.php/acta/article/view/9261 https://acta.tums.ac.ir/index.php/acta/article/download/9261/5770

We investigated the prognostic role of routine laboratory factors including CBC indices and serum vitamin D levels to predict MM recurrence after receiving an autologous stem cell transplant (ASCT). 29 patients were enrolled. Before ASCT, demographic data and CBC, serum Cr, and Vit D levels were obtained. Patients underwent bone marrow aspiration (BMA) and biopsy (BMB) before ASCT and pretransplant plasma cell counts were also evaluated. Patients were followed for 6 months and BMA and biopsy were done in the 3rd and 6th month of the follow-up to detect recurrence. Overall, 9 patients were reported to have recurrence. The patient's WBC count mean was 13.3±11.6. WBC count was lower in patients with overall recurrence (P=0.005). Patients were divided into 2 groups according to WBC count (<5.5 109/L and ≥5.5 109/L) and we found that WBC count <5.5 109/L was associated with increased risk of recurrence by 15.2 times (Odds ratio: 15.2, 95%CI: 1.4-168, P=0.005). We also evaluated Wbc to Hb ratio (Wbc/Hb) and found that Wbc/Hb <1 had a significant statistical relationship with overall recurrence (P=0.026) as patients with WBC/Hb <1 were in 9.8 times increased risk of recurrence (Odds ratio:9.8, 95% CI: 2-93.5, P=0.026). pretransplant WBC <5.5 109/L and WBC/Hb <1 were associated with 9.8 and 15.2 times increased risk of myeloma recurrence and could be useful predictive factors for a patient's short-term recurrence. https://acta.tums.ac.ir/index.php/acta/article/view/9209 https://acta.tums.ac.ir/index.php/acta/article/download/9209/5772

Regarding the major role of C-kit+ BM stem cells in cell therapy of patients with heart disease and getting cells with higher differentiation potential, this study aimed to investigate the capacity and effect of L-carnitine (LC) on cardiomyogenic differentiation of C-kit+ BM cells through MAPK/ERK signaling pathway. For this purpose, C-kit+ was enriched from the BM mononuclear cell population using a magnetic activating cell sorting technique. The purity of the separated C-kit+ cells was then evaluated by flow cytometry. In the next step, C-Kit+ cells were treated in a cardiomyogenic differentiation culture medium for 21 days once in the presence and once in the absence of 0.2 µM LC (the experimental and control groups). To evaluate the cardiomyogenic differentiation potential of C-kit+ cells, the Desmin cell marker was determined by immunocytochemistry. The expressions of both GATA4 and ERK proteins were measured using western blotting and flow cytometry, respectively. The results show that 95.7 percent of the cells separated by the MACS technique expressed a C-kit+ cell marker. Additionally, it was found that 0.2 mM LC significantly increased the expression of GATA4 protein in the cardiomyogenic differentiated cells. The expression of ERK protein also suggested a significant increase of about 1.60 times in the experimental group in comparison with the control group (*P˂0.05). In brief, it was found that treating C-kit+ BM cells with LC increases cardiomyogenic differentiation by increasing the expression of GATA4. Notably, this effect can take place through MARK/ERK signaling pathway. The results of this research can be valuable in suggesting a treatment solution for cardiovascular diseases. https://acta.tums.ac.ir/index.php/acta/article/view/9184 https://acta.tums.ac.ir/index.php/acta/article/download/9184/5773

In the following study, we functionalized wild-type asparaginase with the TMTP1 targeting peptide which specifically targets a variety of hematological and metastatic cancer cells. The peptide sequence was genetically added to the N-terminal end of the asparaginase using the restriction endonuclease-free cloning method. Wild-type and engineered asparaginases were expressed in E. coli and purified by Nickel affinity chromatography column. The in vitro activity of both types of enzymes was evaluated by Nessler’s method. The sequencing results showed that the TMTP1 sequence was added in the correct frame to the asparaginase. Wild-type and TMTP1-fused asparaginases were produced in a soluble state with the specific activity of 172 U/mg and 153 U/mg, respectively. The evidence from this study suggests that TMTP1-fused asparaginase could preserve its solubility and activity compared to the wild-type species and can be proposed for future research in anticancer therapies. https://acta.tums.ac.ir/index.php/acta/article/view/10492 https://acta.tums.ac.ir/index.php/acta/article/download/10492/5774

If osteoporosis's significant features can be identified, the risk of developing this disease will be reduced. In recent years, data mining approaches have become a suitable tool for medical researchers. This study applied data mining methods to identify osteoporosis’s significant features. This study applied data from women having osteoporosis or osteopenia in the period 2011-2019 in the Osteoporosis Diagnosis Center, Isfahan, Iran. Data mining methods such as linear regression, naïve bayes, decision tree, support vector machine, random forest, and neural network were implemented on the dataset. This study consisted of 8258 patients’ information, of which 1482 had osteoporosis. The results showed that the support vector machine, decision tree, neural network are the best method based on accuracy, precision, and AUC measures. Six candidate features were age, weight, back pain, low activity, menopause date, and previous fracture. Support vector machine, decision tree, and neural network are the best candidate techniques for predicting osteoporosis. Thin older people are more at risk of osteoporosis than other people. Yet, people with middleweight and middle age are at lower risk of osteoporosis. https://acta.tums.ac.ir/index.php/acta/article/view/9377 https://acta.tums.ac.ir/index.php/acta/article/download/9377/5775

The incidence of PONV has been estimated in over two-thirds of patients undergoing laparoscopic bariatric surgeries. Prophylactic combined antiemetic therapy is recommended for patients undergoing these surgeries. This is a double-blinded randomized clinical trial. Eighty-three patients of ASA physical status I and II undergoing elective bariatric laparoscopic surgery were enrolled in this clinical trial and divided into two equal groups through simple randomization using a random number table. One group (group A) received a combination of ondansetron, dexamethasone, and haloperidol (ODH); and the other group (group B) received a combination of ondansetron, dexamethasone, and promethazine (ODP). The ODP group received promethazine 25 mg IM 30 minutes before extubation and ODH group received haloperidol 2 mg IM at the beginning of the surgery. Nausea and vomiting were assessed in terms of severity and frequency in the recovery room, 6, and 24 hours postoperatively in both groups using the Numeric Verbal Rating Scale (NVRS). The frequency of PONV was significantly lower in the ODH group compared to the ODP group in the recovery room (20% versus 40%). PONV severity was lower in the ODH group compared to the ODP group. The time to first rescue antiemetic prescription in the ODP group was more than in the ODH group (7.2 h versus 2.6 h). In morbidly obese patients undergoing laparoscopic bariatric surgery, both antiemetic combinations decreased the incidence of PONV, but the combination of haloperidol, dexamethasone, and ondansetron was more effective than promethazine, dexamethasone, and ondansetron. https://acta.tums.ac.ir/index.php/acta/article/view/9107 https://acta.tums.ac.ir/index.php/acta/article/download/9107/5767

To shed further light on this issue, we present a case series of 22 pregnant ovarian cancer patients referred to an academic hospital's gynecology oncology department over six years. Data on each patient's demographic and clinical background were collected using a registry software recording surgical tumor staging, disease-free survival (DFS), and overall survival (OS). According to the data analysis reports, subtype epithelial tumor and germ cell pathology were equally 45.4%. However, sex-cord tumors were observed in a smaller percentage of cases (9.1%). Serous adenocarcinoma was the most common subtype among those with epithelial tumors (60%). Meanwhile, 72.7% of these pregnant women had a palpable mass in physical examination. In addition, adnexal mass was detected in 95.4% of ultrasonography. Due to the young age of the patients, fertility-preserving surgery was performed on 63.6% of patients, and chemotherapy was prescripted on 59% of patients. Over a six-year follow-up period, there was a recurrence rate of 22.7%, while DFS and OS were reported as 56% and 82%, respectively. In conclusion, treatment of ovarian malignancies during pregnancy requires an experienced multidisciplinary approach. However, more extensive studies with larger samples are needed to gain more insight into the treatment of ovarian cancer during pregnancy.   https://acta.tums.ac.ir/index.php/acta/article/view/9104 https://acta.tums.ac.ir/index.php/acta/article/download/9104/5768

Of these, venous malformations represent 1% of all parapharyngeal space tumors. In the current paper, we reported a 5-year-old patient who presented with a soft tissue swelling of the parapharyngeal space that was discovered by her parents after two weeks following adenoidectomy. The MRI revealed a tumour within the parapharyngeal space with a well-defined mass with low-signal intensity on T1 and high on T2. The internal flow voids also proposed phleboliths. Therefore, the tumour was removed by an intraoral approach. The post-op pathology result explicated a venous malformation. https://acta.tums.ac.ir/index.php/acta/article/view/9001 https://acta.tums.ac.ir/index.php/acta/article/download/9001/5763
