Despite some improvements in treatment, the survival rate is still very low, mainly due to the possible development of secondary malignancy or metastasis. Clinical and pathological features as well as molecular biomarkers might predict the recurrence. In recent years, many studies have been carried out on molecular biomarkers that can predict the prognosis of OSCC. One of these markers is the epidermal growth factor receptor (EGFR), which has led to different results. The aim of this study was to determine EGFR level in OSCC and to analyze its correlation with clinicopathological features. Methods: A total of 62 paraffin-embedded samples from OSCC patients treated in the oncology department of the Omid Hospital in the city of Mashhad, Iran were selected and EGFR staining was performed. The clinical and histopathological data were extracted from the medical records. Results: EGFR expression was positive in 98.4% of the cases. There was a significant difference between EGFR expression in the tumor and control cases in terms of cellularity and intensity (p˂0.001 and p=0.004, respectively). No statistically significant correlation was observed between EGFR and clinicopathological parameters. There was also no significant relationship between the cellularity and intensity expression of EGFR and patient survival (p=0.92 and p=0.42, respectively). Conclusion: In view of the high EGFR expression in squamous cell carcinoma, further studies on the role of EGFR in cell processes such as proliferation, angiogenesis and differentiation of the tumor are recommended.}, keywords = {Oral carcinoma,Squamous cell,Epidermal Growth Factor,survival rate,immunohistochemistry}, url = {https://jkmu.kmu.ac.ir/article_91015.html}, eprint = {https://jkmu.kmu.ac.ir/article_91015_71ba1a85beba1861481e5f4cfcd15da1.pdf} } @article { author = {Moazenzadeh, Mansoor and Mohammadi, Khadijeh and Sarafi Nejad, Afshin and Karimi Afshar, Fatemeh and Rashidinejad, Hamidreza}, title = {The Impact of Cardiac Rehabilitation on Pulmonary Artery Systolic Pressure and Left Ventricular End-Diastolic Pressure in Patients after Coronary Artery Bypass Graft Surgery}, journal = {Journal of Kerman University of Medical Sciences}, volume = {27}, number = {4}, pages = {294-303}, year = {2020}, publisher = {Kerman University of Medical Sciences}, issn = {1023-9510}, eissn = {2008-2843}, doi = {10.22062/jkmu.2020.91016}, abstract = {Background:Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LVEDP). Methods: This Quasi-experimental study with pretest-posttest design was conducted on 80 patients with IHD who had participated in CRP after undergoing coronary artery bypass graft (CABG) surgery. Echocardiography was performed before the beginning of CRP (the 1st session) and at the end of the rehabilitation sessions, and ventricular function indices (ejection fraction), PASP (using the tricuspid regurgitation velocity), and LVEDP (using Nagueh formula: 1.24×E/e´+1.9) were measured. Results: Ejection fraction (EF) was changed from 49.3 ± 7.8 before rehabilitation to 50.7 ± 7.4 after rehabilitation, which was a statistically significant difference (P=0.003). The pulmonary artery systolic pressure altered from 30.3 ± 8.4 before rehabilitation to 27.3 ± 6.6 after rehabilitation. The left ventricular end-diastolic pressure (LVEDP) changed from 10.5 ± 3.7 before rehabilitation to 9.1 ± 2.9 after rehabilitation, which was a statistically significant difference (P= 0.000).

Pyruvate Dehydrogenase Kinase 4 (PDK4) is one of the main enzymes that play a critical role in metabolic flexibility. In current study, we examined PDK4 inhibition along with exercise training (ET) on the gene expression of Estrogen related-receptor alpha (ERRα), medium-chain acyl-CoA dehydrogenase (MCAD), carnitine palmitoyl transferase-1b (CPT-1b), peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), PDK4 and citrate synthase (CS) in skeletal muscle.Method:Sixty-four male Wistar rats (8 week-old) were randomly divided into 8 groups (n=8); 1- untreated control, 2- STZ-induced diabetic, 3- PDK4 inhibition, 4- endurance training (ET), 5- diabetic + PDK4 inhibition, 6- diabetic + ET, 7- PDK4 inhibition + ET, and 8- diabetic +ET + PDK4 inhibition. ERRα, MCAD, CPT-1b, PGC-1α, PDK4 and CS genes expressions were measured by Real-Time PCR and quantified by 2-ΔΔCt method.Results:ERRα, MCAD, CPT-1b, PGC-1α, PDK4, and CS expressions were significantly higher in non-diabetic+ Endurance Training group compared to the control group. The expressions of CPT-1b, MCAD and CS genes were significantly lower in the non-diabetic+ endurance training/PDK4 inhibition compared to the non-diabetic+ endurance training group, and the expressions of ERRα, CPT-1b and MCAD were significantly lower in the diabetic + PDK4 inhibition group compared to the diabetic group.Conclusion:In sum, PDK4 inhibition has negative effects on lipid metabolism in healthy rats, but in animals with diabetes, PDK4 inhibition can be used for improving lipid metabolism (over-expression of CS and PGC-1α).}, keywords = {Pyruvate Dehydrogenase Kinase 4 Endurance Training Metabolic Flexibility Estrogen,Related Receptor}, url = {https://jkmu.kmu.ac.ir/article_91017.html}, eprint = {https://jkmu.kmu.ac.ir/article_91017_021aed81532676834f8ec4d03e11a763.pdf} } @article { author = {Delbari, Ali and Nazm Bojnordi, Maryam and Mojaverrostami, Sina and Ghasemi Hamidabadi, Hatef and Bagheri‑Hosseinabadi, Zahra and Rezaei, Nourollah}, title = {A Novel in vitro Co-culture Systems on Differentiation of Embryonic Stem Cells into Oocyte-like Cells in an in vivo Manner}, journal = {Journal of Kerman University of Medical Sciences}, volume = {27}, number = {4}, pages = {318-328}, year = {2020}, publisher = {Kerman University of Medical Sciences}, issn = {1023-9510}, eissn = {2008-2843}, doi = {10.22062/jkmu.2020.91018}, abstract = {Background:Differentiation of Embryonic Stem Cells into Oocyte-like cells in vitro is challenging. Successful derivation of oocyte from stem cells can provide an alternative source for curing ovogenesis problems. The current study aims to demonstrate a new protocol with two different types of media for differentiating embryonic stem cells (ESCs) into oocyte-like cells (OLCs). Methods: After culturing mouse ESCs, embryoid bodies (EBs) were generated from ESCs by hanging drop (HD) method. To final differentiation of oocyte-like cells (OLCs), the EBs were cultured in two different types of media for 12 days (first 7 days EBs were cultured in in vitro maturation diluted in Granulose Cell- Conditioned Medium and Follicular Fluid [1:1:1] followed by 5 days of culture in in vitro maturation diluted in uterine condition medium [1:1] ). Results:According tothe MTT test, the viability rate increased in the experimental group compared to the control EBs cultured alone. Expression of Oct4, as a pluripotency marker, decreased during the differentiation process of EBs in the experimental group. Co-culturing of EBs with our mentioned protocol increased germ cell markers (Stella and Mvh) and increased Oocyte-specific markers (ZP1, Figα and GDF9).

The aim of the present study was to assess the importance of AMH in predicting live birth following intrauterine insemination (IUI) in the case of low or very low ovarian reserve. Methods: In this retrospective cohort study, 123 patients with AMH≤1 ng/ml, who underwent a total of 137 IUI cycles were enrolled and evaluated for live birth rate. Patients were divided into two groups based on serum AMH levels: group 1 with low level of AMH (0.4-1 ng/ml, n=83, cycles: 95) and group 2 with very low level of AMH (≤0.4 ng/ml, n=40, cycles: 42). The results were compared between the two groups. Main outcome was the pregnancy rate. Results: The rates of biochemical pregnancy, clinical pregnancy and live birth in all patients were 11%, 8% and 7.3%, respectively. The two groups showed no significant difference in the rates of biochemical pregnancy (10.4% vs. 14.3%, p=0.3), clinical pregnancy (6.3% vs. 11.9%, p=0.2) and live birth (6.3% vs. 9.8%, p=0.5).
