Infertility is one of the disorders that worries many couples around the world, although novel and molecular methods can be used to cure this disease in different stages. One of the factors that causes infertility in men and women is the increased oxidative stress within the cells, which can lead to damage in zygote formation. ROMO1 is one of the most important proteins in the production of reactive oxygen species. This protein can enhance oxidative stress in the cells and body through cellular pathways, such as TNF-α and NF-κB routes, which will eventually lead to many diseases, especially infertility. We engage several international databases by using keywords; ROMO1, Infertility, and Reactive Oxygen Species, and gained a great quantity of information about ROMO1, Infertility, and Oxidative Stress. Although not proven, it is hypothesized that ROMO1 might elevate oxidative stress by activating NF-κB pathway in the cells, furthermore, TNF-αcan arouse ROMO1 that can end up with apoptosis and cell death, which consequently can have a lot of disturbing effects on the body, especially the reproductive system. To sum up, revealing the exact cellular and molecular mechanisms of ROMO1-dependent TNF-α and NF-κB pathways in the pathogenesis of infertility might find interesting therapeutic and management strategies for this disorder.

Gastric Cancer (GC) is one of the most dangerous malignancies in the world. This study aims to evaluate the relationship between miR-146a and miR-155 in patients with H. pylori infections with GC compared to H. pylori-infected patients and healthy subjects. Forty patients with H. pylori and GC positive diagnoses and 40 patients with H. pylori positive and GC negative diagnoses, and 40 healthy persons were selected.The expression of miR-146a and miR-155 genes in the whole blood was examined using qRT-PCR. Moreover, ROC curves were drawn to represent the sensitivity and specificity of miR-146a and miR-155 expression as biomarkers. The results showed the expression of miR-146a and miR-155 in the whole blood of patients with H. pylori and GC positive diagnoses are significantly higher than in healthy individuals and are non-significantly enhanced compared to H. pylori positive and GC negative. Also, the results stated miR-146a and miR-155 expression in the whole blood of patients who are H. pylori positive and GC negative are significantly increased compared to healthy individuals. Furthermore, the ROC curve analysis of miR-146a and miR-155 RNA level demonstrated the two miRNAs have an appropriate sensitivity and specificity for diagnostic goals. In conclusion, H. pylori infection may increase the expression of miR-146a and miR-155 in patients with H. pylori and GC positive diagnoses, which can be effective in the curbing the progression of GC. For this reason, up-regulation of miR-146a and miR-155 along with H. pylori infection might contribute to the pathogenesis of GC, and also can be suggested as biomarkers for GC diagnosis and treatment.

Introduction: Sleep disorder is one of the most common problems in elderly people. The present study is focused
on the effectiveness of educational intervention on sleep quality and psychological well-being in the elderly people.
Method: This is a Randomized educational field-controlled trial which was conducted on 90 elderlies with the sleep
disorder, who have been selected using systematic random sampling from the clients of comprehensive health centers in Borazjan, Iran, 2019. The educational intervention was presented for 5 weeks by lecture, group discussions
and virtual learning methods. Data were collected by the Pittsburgh Sleep Quality Index and the Ryff’s Psychological
well-being scale before and 2 months after the intervention. The data were analyzed using SPSS-25 software using
independent t-test, and Chi-square test. Results: The results showed significant statistical differences in sleep quality, subscales of sleep efficiency, sleeping time, and taking sleeping pills in experimental and control groups after
the intervention (p≤0.005). Moreover, significant statistical difference was observed in terms of the mean scale of
psychological well-being between experimental and control groups (p=0.036). Conclusion: Behavioral interventions
can make various advantages for elderly people. Therefore, this study suggests providing such interventions in a wide
range in comprehensive health centers, and boarding centers for the elderly.

AIM: To evaluate the role of a single intravitreal injection of tissue plasminogen activator ( TPA) alone for treatment of vitreomacular traction and the effect of combined intravitreal TPA and bevacizumab on retinal vascular diseases.? METHODS: In this prospective, interventional case series a total of 24 eyes from 24 patients were studied. There were 5 eyes with symptomatic vitreomacular traction syndrome ( VMT ) and 19 eyes with retinal vascular diseases including diabetic macular edema ( DME ) , diabetic vitreous hemorrhage ( VH ) , central retinal vein occlusion ( CRVO ) and neovascular age related macular degeneration ( AMD ) . Measurement of visual acuity, B-scan and OCT were performed at the baseline and 1mo after injections. Three eyes with VMT received a single intravitreal injection of 50 μg and two eyes received 100 μg TPA. And 19 eyes with retinal vascular diseases received combined intravitreal TPA ( 50μg) and bevacizumab (1. 25 mg).?RESULTS: The mean ages for retinal vascular diseases and VMT patients were 56. 8y and 60. 4y, respectively. Ten patients ( 41. 7%) were male and 14 patients ( 58. 3%) were female. And 22 eyes ( 91. 7%) were phakic and 2 eyes ( 8. 3%) were pseudophakic. The incidence of posterior vitreous detachment (PVD) was 0 (0 of 5) and 57. 8% (11 of 19) for VMT and retinal vascular diseases, respectively (P= 0. 04). Improvement of best corrected visual acuity ( BCVA ) and decrement of central macular thickness ( CMT ) were significantly greater in PVD positive eyes compared with PVD negative eyes.?CONCLUSION: Intravitreal injection of TPA was not successful to induce complete PVD in VMT patients. Combined intravitreal injection of TPA and bevacizumab can induce PVD and improve BCVA and decrease central macular thickness in eyes with retinal vascular diseases.

AIM: To compare the anterior and posterior corneal astigmatism and total refractive astigmatism before and after MyoRing implantation in keratoconus(KCN)patients.METHODS: In this historical cohort study, the preoperative and postoperative total refractive, anterior and posterior corneal astigmatism of KCN patients implanted with a 360-degree full-ring implant(MyoRing)were compared before and after four consecutive follow-up sessions at 3, 6, 9, and 12 mo after surgery.RESULTS: The study encompassed 79 KCN patients(85 eyes), comprising 43 males and 36 females. The mean age of the patients was 29±7.41 years, ranging from 17 to 48 years. Throughout the follow-up sessions, a gradual decrease was observed in the trend of changes for total refractive astigmatism, anterior corneal astigmatism, and posterior corneal astigmatism. Postoperatively, total refractive astigmatism measurements exhibited a significant decrease of 2.09 D at 12 mo after MyoRing implantation(4.27±3.15 vs 2.18±1.63 D, P<0.001). Additionally, post-operative measurements revealed an enhancement of approximately 3.20 D and 0.59 D for anterior and posterior corneal astigmatism, respectively [6.40±1.90 vs 3.20±1.75 D for anterior corneal astigmatism(P<0.001)and 1.30±0.55 vs 0.71±0.35 D for posterior corneal astigmatism(P<0.001)].CONCLUSION: MyoRing implantation demonstrates significant improvements in astigmatism parameters, encompassing total refractive astigmatism as well as anterior and posterior corneal astigmatism.
