Background and Aim: The power of chemotherapy on prolonging and improving the life of patients is undeniable, but it often consists of various side effects. Therefore, developing of effective strategies for reduction of chemotherapy drugs toxicity is necessary. Natural products including frankincense - derived products have been demonstrated to reduce chemotherapy side effects. The aim of this study was to diminish the side effects of Busulfan - Cyclophosphamide (Bu - Cy) regimen as chemotherapeutic agents with the aid of frankincense derivatives administration in the mice model.

Methods: The chemotherapy conditioning regimen was created in Female Balb / c mice by intraperitoneal injection of 60 mg Busulfan and 150 mg Cyclophosphamide per kg of mice. Frankincense derivatives including essential oil (Ess), soxhlet oil (Sox) and n-hexane extract (Ext) were extracted and injected intraperitoneally to chemo - conditioned mice.

Results: As expected, mice treated with Bu - Cy chemotherapy had lower bone marrow cells count and spleen index compared to the control, whereas frankincense derivatives helped reducing side effects and modifying immune system and general health.

Conclusion: Despite that all three extracts have decreased the side effects of chemotherapy; Ext could simultaneously increase the spleen index and the bone marrow cells count and also improve the health in comparison with the negative control group.

Mesenchymal stem cells (MSCs) with their spindle like shapes are a lineage of stem cells with the capacity to self-renew and differentiate into osteoblasts, adipocytes, and chondrocytes and with CD105, CD73, and CD90 expression and the lack of CD34, CD14, CD45, and HLA - DR expression. The immunomodulatory, angiogenic, antiapoptotic, antimicrobial, and antioxidative characteristics of these cells made them more attractive in the field of cell - therapy for several autoimmune and inflammatory diseases, including diabetes, neurological disorders, sepsis, cardiac ischemia, and GvHD. For this reason, various protocols have been proposed to isolate mesenchymal stem cells from different tissue sources, such as adipose tissue (AT), umbilical cord (UC), Wharton’s jelly (WJ), bone marrow (BM), dental pulp, and even menstrual fluid. Considering the ease of access to the umbilical cord tissue and the fact that this tissue is rich in MSCs with embryonic origin and higher proliferation rate and lower senescence of the cells, the umbilical cord became a suitable source for explant MSC culture. In this study, we decided to introduce an explant culture protocol of MSCs that is less expensive and cost - effective achieving a high yield of MSCs.

Background and Aim: Case fatality ratio (CFR) is an indicator of disease severity that can help policymakers make decisions. This study aims to evaluate the trend of CFR of hospitalized COVID-19 patients since the outset of the pandemic in Iran and identify variables that affect CFR.

Methods: 5318 confirmed COVID-19 inpatients were enrolled in this multicentric observational study. Patients admitted from March 20, 2020, to March 18, 2021, in three general hospitals were collected. The medical team gathered patients’ demographics, past medical history, and outcomes by reviewing patients’ medical records. The time trend of CFR was investigated by joinpoint regression analysis to calculate weekly percent change (WPC) and confidence interval (CI).

Results: Significant upward trend was observed in CFR of hospitalized COVID-19 patients during study weeks (WPC= 1.2, 95% CI: 0.7, 1.7; P < 0.001). The increase was more evident in men than in women (WPC: 1.4 vs. 1.1). The rise of CFR was observed in patients with cancer (WPC: 4.5), dialysis (WPC: 2.1), diabetes (WPC: 1.0), and old age (WPC: 1.0).

Conclusion: There was a significant rise in the trend of in-hospital CFR from March 2020 to March 2021 in Iran. This rise was also evident with the same rate in patients with old-age and DM. However, the rate of this rise was higher in male and cancerous patients. Worldwide variation was reported by few studies investigating the trend of hospital CFR, and further studies are warranted.

Background and Aim: Breast carcinomas with metastasis to lungs and primary lung adenocarcinomas have significant overlap. This study aimed to investigate the differential expression of a panel of IHC markers in primary lung adenocarcinomas and invasive ductal carcinomas (IDC) of the breast.

Methods: In this cross sectional study, total of 50 specimens including 25 primary lung adenocarcinomas and 25 invasive ductal carcinomas of the breast were collected from Masih Daneshvari and Shohada-e-Tajrish hospitals. After all of the cases were stained with hematoxylin - and - eosin, the histologic diagnosis and grading of the slides were reviewed and reported by experienced pathologists based on standard classifications. The patients’ medical records were reviewed for demographic data, clinical information and histopathologic reports.

Results: The median age of the patients with lung adenocarcinoma and IDC was 59 (32-78) and 50 (35-74) years, respectively. In this study, regarding lung adenocarcinomas, the most common type was acinar (56%), followed by solid (20%), mucinous (16%), lepidic (4%), and colloid (4%). Immunohistochemical expression for Napsin-A, TTF-1, ER, GCDFP-15, and GATA-3 in primary lung adenocarcinomas and invasive ductal carcinomas of the breast were different.

Conclusion: Napsin-A, TTF-1, ER, GCDFP-15, GATA-3 and GATA-3 Markers can differentiate the breast cancer from lung adenocarcinoma. Napsin-A and TTF1 only present in lung adenocarcinoma.

Increasing serum albumin in patients with hypoalbuminemia does not inhibit serum angiotensin-converting enzyme activity

Student Research in Translational Medicine, Vol. 5 (2023), 30 December 2023,

Introduction: Angiotensin-converting enzyme (ACE) plays a pivotal role in the production of angiotensin II and the inactivation of bradykinin. Recent studies have suggested that human serum albumin may possess ACE-inhibitory properties, serving as a potential endogenous ACE inhibitor that primarily affects serum ACE levels. Interestingly, the infusion of albumin in the postoperative phase of cardiac surgery has been associated with the development of hypotension.

Methods: This study aimed to assess serum ACE activity in 27 hypoalbuminemia patients admitted to the ICU before and after a protein-rich diet was administered to raise their serum albumin levels. Serum ACE activity was quantified using raas(HPLC), measuring the formation of hippuric acid, a product generated during the incubation of serum with Hip-His-Leu, a substrate, at 37°C for 30 minutes.

Results: In vitro experiments demonstrated that the addition of albumin to human sera led to a significant reduction in ACE activity compared to control groups (P < 0.0001). This reduction was consistent across all serum samples. Specifically, the maximum velocity (Vmax) of ACE activity significantly decreased from 14.90 U/L in the control group to 3.210 U/L in the albumin-added group (P = 0.0262). Notably, there was no significant change in the Michaelis constant (Km) between the control group (0.5263 mM) and the albumin group (0.2742 mM) (P = 0.6763), indicating a non-competitive inhibitory effect of albumin on ACE activity. Interestingly, in this study, elevating serum albumin levels in hypoalbuminemia patients following a protein-rich diet resulted in both ACE inhibition and a slight increase in activity (P = 0.0201). This increase correlated mildly with serum albumin levels across all samples.

Conclusions: In conclusion, contrary to in vitro findings, raising serum albumin levels in hypoalbuminemia patients did not further inhibit serum ACE activity.

Case Report

Perforated gastric ulcer (PGU) is exceedingly uncommon in children. In a child with acute abdomen and Pneumoperitoneum, an Appendiceal etiology is more often suspected as a likely cause. Failure or delay to diagnose a PGU can result in significant morbidity and even mortality.

We report a 10 years old girl with abdominal pain for 2 days with PGU. We did examination and we found generalized abdominal pain and performed Laparatomy and we found perforated gastric ulcer and repair with Omental patch. PGU is an uncommon cause of peritonitis in children and poses significant challenges in management. Strong suspicion and prompt appropriate intervention is necessary to avoid untoward outcomes. Researchers conclude that GOO secondary to ulceration can occur in the absence of H. pylori infection. PPU is a rare cause of abdominal pain in children, but still a PUD complication that requires surgery. PPU should be included in the differential diagnosis in patients presenting with acute abdominal pain of uncertain etiology and pneumoperitoneum. Laparoscopy is both diagnostic and therapeutic. Laparoscopic omental patch repair is a safe and effective treatment for PPUs. This case illustrate that perforated peptic ulcers should be considered in children presenting with acute abdomen.

Student Research in Translational Medicine, Vol. 5 (2023), 30 December 2023,

Congenital colonic stenosis is a condition in which there is a narrowing or blockage of the colon (large intestine) present at birth. This can occur due to multiple etiologies, including abnormal development of the colon during fetal development and some genetic defects. The condition may lead to symptoms such as abdominal pain, on and off constipation, abdominal distention and vomiting. Treatment may involve surgery to remove or widen the narrowed segment of the colon.

Background and aim: Intrauterine adhesions (IUAs), also known as Asherman's syndrome, is a prevalent gynecological condition that presents with various clinical manifestations, including atypical menstrual patterns, pelvic discomfort, reduced endometrial thickness, repeated pregnancy loss, and potential infertility. Despite advancements in therapy, the successful pregnancy rate remains low, especially in severe cases, posing significant therapeutic challenges and poor prognoses. Therefore, extensive research is essential to understand the underlying mechanisms of IUAs and develop effective therapeutic interventions.

Materials and Methods: This study introduces a novel method of incubating co-culture of stem cells and intraperitoneal macrophages with hydrogen peroxide (H2O2) and scratch wound to mimic impaired endometrial stromal cells, considering the regenerative properties of macrophages, and prominent leukocytes in the endometrium. The objective was to examine the co-culture endometrial stem cells (EnSCs) of the human uterus and intraperitoneal macrophages as an in vitro model for IUAs. The aim was to establish a physiologically relevant model that replicates the complex cellular interactions and microenvironment observed in the endometrium during IUAs development and investigate the influence of macrophages on the response of stem cells to H2O2.

Results: The study involved culturing and preparing EnSCs in a 24-well plate, while peritoneal macrophages were isolated through lavage in mice. Four experimental groups were established: EnSCs alone (group A), EnSCs treated with H2O2 (group B), EnSCs co-cultured with macrophages (group C), and EnSCs co-cultured with macrophages treated with H2O2 (group D). In all groups, the wound was mimicked by a sterile crystal tip. Cell viability was assessed using the MTT test, measuring the reduction of tetrazolium salt to formazan crystals. Nitric oxide (NO) production was measured using the Griess reaction, and cell migration was evaluated through a scratch wound healing assay. Statistical analysis utilized Student's t-test or one-way ANOVA, with GraphPad Prism version 6 software, considering results with p< 0.05 as statistically significant.

Conclusion: The findings indicated that H2O2 treatment had a negative impact on EnSCs viability, but co-culturing with macrophages provided a protective effect. Moreover, H2O2 treatment led to increased NO levels, suggesting macrophage activation against oxidative stress. Interestingly, H2O2 treatment promoted cell migration in both EnSCs alone and the co-culture, while macrophages inhibited migration. These results underscore the significance of the interaction between EnSCs and macrophages in understanding IUAs and developing effective treatments

Student Research in Translational Medicine, Vol. 5 (2023), 30 December 2023,

A 44-year-old man with a three-day history of pain in right axilla, subsequently accompanied by the appearance of vesiculopapular rashes on the right portion of his torso, attended a medical facility. The patient had neither reported any special skin contact in that area, nor fever and other symptoms. Upon examination, the examiner revealed the appearance of some other similar vesiculopapular rashes. These two affected sites were located in a linear arrangement, namely, the T7 dermatome. Considering the particular arrangement of rashes and form of manifestation, a clinical diagnosis of herpes zoster was made. The patient underwent empirical treatment of herpes zoster, including Virabex (valaciclovir) tablet 1g TDS, pregabalin capsule once nightly, and hydroxyzine hydrochloride tablet once every night. The pain and itching resolved within one week after the prescription, and the rashes mostly disappeared within 20 days. Here, the daily state of rashes are presented to the audience.
