Research, as systematic way to discover, interpret, explain, predict, modify, and control events, entails the knowledge-based performance of individuals, organizations and systems. Today, knowledge is a tool for development, entrepreneurship, and improving economic value added rather than be a product of development. Also, Health systems, with their increasing complexity and scope, are causes and especially effects of an increasing rate of production, translation and implementation of health-related knowledge. This knowledge, with complexity, vast range, and variety, is produced by variety of research projects which mainly resulted from different problems addressed and presumed epistemic positions by them.

Authors believe that a comprehensive outlook on the variety of research projects in the health system could help to change the stereotypical view on research in the health system. To the best of our knowledge, this paper is a novel, narrative review gathering and presenting various existing classifications of research projects in the light of an inductive distinction. It aims to help specialists in the different levels of health system to profoundly understand and meticulously apply research results and to help researchers and research bodies to more accurately define, manage, prioritize, and allocate resources for future research projects to solve upcoming problems.

Different aspects used in this paper to classify health research projects are the followings: The purpose of research, the research paradigms, tacit or explicit knowledge, primary or secondary knowledge, relation with known disciplines, functions of the health system, the partnerships of non-academic persons, decision-making level, taxonomy of questions, and levels of evidence.

Background: Type 2 diabetes and its relationship with cardiovascular diseases is one of the concerns of today's society. Although the favorable role of aerobic exercise and gymnema sylvester supplement consumption in diabetic patients has been reported, the effect of aerobic exercise and gymnema sylvester supplement consumption on heart tissue is not well known. Therefore, the purpose of this research is Comparison of the effect of aerobic exercise and gymnema sylvestre supplement on some markers related to cardiomyopathy in type 2 diabetic mice.
Methods: The present research was experimental. The statistical samples included 40 male C57BL/6 mice (with an average age of 8 to 10 weeks and a weight of 20 to 25 gr). who became diabetic after 20 weeks of feeding with a high-fat diet. Then randomly divided into five eight groups including: diabetes + exercise (TDM), diabetes + gymnema sylvester (GSDM), diabetes + exercise + gymnema sylvester (TGSDM), diabetes (DM) and healthy control (CN). The aerobic exercise program consisted of exercises at a speed of 10 m/min for six weeks and five training sessions per week on a treadmill. Daily consumption of gymnema sylvester at the rate of 0.1 g/kg orally alone and also with training intervention was done for six weeks. Serum glucose concentration was measured by enzymatic method, insulin level by ELISA method, insulin resistance by HOMA-IR method and expression of CASPASE-1 and NLRP3 genes by RT-PCR method. Data evaluation was calculated using covariance statistical test and Bonferroni's post hoc test, the significance level was considered as P≤ 0.05.
Results: The findings showed that aerobic exercise and gymnema sylvestre supplement alone caused a significant decrease in the levels of glucose, insulin, insulin resistance and the expression of CASPASE-1 and NLRP3 genes in the heart tissue (P≤ 0.05), the largest decrease in the dependent variables related to the aerobic exercise group with Gymnema Sylvester supplement (P≤0.05). Also, there is no significant difference between the dependent variables of the diabetes group and aerobic exercise and the diabetes group and Gymnema Sylvester supplement (P≤ 0.05).
Conclusion: Six weeks of aerobic exercise, gymnema sylvester supplement and aerobic exercise combined with gymnema sylvester supplement improves blood variables by reducing glucose, insulin and insulin resistance, as well as improving markers related to cardiomyopathy by reducing the expression of caspase-1 and NLRP3 genes in the heart tissue in type 2 diabetic mice.

Background: The purpose of the research was to compare the effect of two types of aerobic exercise—with and without incline—on the modulation of oxidative stress and kidney function in chronic kidney disease (CKD) mice.
Methods: A total of 24 two-month-old female C57b16 mice weighing 25±26.1 grams, were randomly divided into four groups: healthy control, CKD-affected mice, CKD mice undergoing aerobic exercise without incline, and CKD mice undergoing aerobic exercise with incline. To induce CKD, they received adenine powder at a concentration of 0.2% mg/kg for four weeks. The training groups performed eight weeks of treadmill training (five sessions per week), whit one group exercising on a 20-degree incline and the other on a zero-degree incline. After the last training session, blood samples were collected to measure blood urea nitrogen, urea and glutathione concentration using the ELISA method. The expression levels of the SIRT1, NRF1 and TNF-α genes were measured using qPCR (Real-Time PCR) technique. For statistical analysis, a one-way ANOVA test and Tukey's post hoc test were employed, with a significance level set at P≤ 0.05.
Results: The results showed that the induction of CKD caused a significant increase in blood urea nitrogen and a significant decrease in glutathione concentration compared to the healthy control group (P< 0.05). Conversely, in the exercise groups, there was a significant increase in glutathione concentration and a significant decrease in blood urea nitrogen (P< 0.05). The expression level of SIRT1 and NRF1 in the slope training group increased significantly, while the expression level of TNF-α decreased significantly (P< 0.05).
Conclusion: Exercises performed on an incline moderates oxidative stress through the TNFα/SIRT1/NRF1 signaling pathway, improving glutathione concentration and blood urea nitrogen levels in mice with chronic kidney disease. Furthermore, the effects of incline exercise were found to be superior to those of exercise without incline.

Background: The current study aimed to ascertain the impact of pulsed magnetic therapy, multicomponent exercise, and a combination of both modalities on bone markers type 2 diabetic patients with osteoporotic.
Methods: In a randomized controlled clinical trial study, 56 older patients with type 2 diabetic osteoporosis (age: 68.18±3.67 yr; weight: 78.13±7.65 kg, body mass index: 28.40±1.76 kg/m2) were randomly assigned to either the multicomponent exercise + Full-body pulsed electromagnetic field (MCEx+PEMF, n= 18) multicomponent exercise + placebo full-body PEMF (MCEx+PPEMF, n=17) and a full-body PEMF alone (PEMF, n= 21). PEMF was applied for the whole body using a full-body mat three times per week, 60 minutes for 12 weeks, with a multicomponent exercise protocol that includes flexibility, aerobic exercise, strengthening, weight-bearing, and balance exercises followed by whole-body vibration (WBV) training. The body composition, bone mineral density (BMD), bone metabolism markers (phosphorus, calcium, sclerostin, osteocalcin, Bone-specific alkaline phosphatase (BALP)) before and after the intervention. The data were analyzed using the dependent t test and the two-way repeated measures ANOVA at the level of less than 0.05.
Results: After 12 weeks of intervention, there is a significant difference in the serum levels of bone mineral density and bone metabolism markers (phosphorus, calcium, sclerostin, BALP) between the groups (P< 0.05). However, the bonferoni post-test showed an increase in serum levels of BMD, phosphorus, sclerostin, BALP with a significant decrease in calcium in the MCEx+PEMF group in compared to alone PEMF group.
Conclusion: The findings showed that the PEMF rehabilitation method combined with multicomponent exercise is more effective and safer than exercise or PEMF only for improving BMD and bone metabolism markers in the type 2 diabetic population with osteoporosis. Therefore, exercise rehabilitation clinics should be encouraged to consider exercise rehabilitation as a treatment method for type 2 diabetic patients with osteoporosis. More studies with long-term follow-up should be considered to confirm these findings.

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women and has lifelong health effects. This study aimed to investigate the physiological effects of PCOS on neurogenesis and cognitive symptom improvement through lifestyle changes and the use of complementary and alternative medicine.
Methods: In this experimental study, 30 female C57BL/6 mice with a mean weight of 18±2 kg and an age of 6 to 7 weeks were randomly divided into five groups: control group, polycystic group, polycystic + swimming exercise group, polycystic + soy group, and polycystic + exercise + soy group. Real-time PCR measured gene expression. Genes were selected with the help of bioinformatics software. ELISA evaluated luteinizing hormone(LH ) concentration.
Results: FN1-ARC-NGFR-BDNF genes showed decreased expression in mice with PCOS compared to the control group. On the other hand, the expression of FN1-ARC-NGFR-BDNF genes in mice with PCOS, swimming training, and soy supplement consumption significantly increased compared to the PCOS group. Simultaneous administration of swimming training and soy supplement consumption significantly increased LH concentration (p<0.001) and expression of FN1-ARC-NGFR-BDNF genes (p<0.05).
Conclusion: This study showed that combining swimming training and soy extract consumption can enhance neurogenesis in a PCOS model and improve cognitive symptoms. Our findings confirm that this combination not only enhances the function of the nervous system but also contributes to overall health improvement through hormonal regulation. These results provide a new avenue for complementary therapies in the management of PCOS.

Background: Type 2 diabetes is a common chronic metabolic disease whose effective management requires attention to psychological and interpersonal factors. This study aimed to examine the relationship between the Perceived Spousal Sacrificial Behavior and self-efficacy with behavior management in patients with type2 diabetes.
Methods: This descriptive-correlational and cross-sectional study was conducted among married patients with type 2 diabetes who were referred to endocrinology and metabolism centers and primary health care units in Sari, Iran. Based on inclusion and exclusion criteria, 97 participants were selected using purposive sampling. The research instruments included the Perceived Spousal Sacrifice Scale (Harper & Figuerres, 2008), the Diabetes Self-Efficacy Scale (Fappa et al 2016), and the Behavioral Management Scale (Toobert et al., 2000). Data were analyzed using SPSS version 24 through descriptive statistics (mean, standard deviation) and inferential statistics (Pearson correlation coefficient and multiple regression analysis).
Results: Perception of the Perceived Spousal Sacrificial Behavior and self-efficacy showed a significant positive correlation with behavioral management among diabetic patients (p < 0.01). Together, these variables explained 30% of the variance in behavioral management, with Perceived Spousal Sacrificial Behavior making a greater contribution to prediction.
Conclusion: The findings highlight the significant role of Perceived Spousal Sacrificial Behavior and self-efficacy in improving behavioral management among patients with type 2 diabetes. Enhancing spousal support and strengthening patients’ self-efficacy through educational and psychological interventions may promote better self-care behaviors and disease control.

Background: Biobanks are biological repositories that collect, process, store, and distribute human biological samples. Among them, tumor banks play a central role in biomedical research. The overall goal of a tumor bank is to collect cancerous and normal samples under standardized conditions for basic, clinical, or applied research.
Methods: Tumor samples from patients with endocrine neoplasms were collected from excess tissue samples not required for diagnostic purposes after surgery in the surgical department of Dr. Shariati Hospital, Tehran, Iran. In addition, relevant biological samples such as serum, plasma and DNA were collected in parallel. Prior to sampling, informed consent was obtained from the patients and a questionnaire was completed. After rapid freezing with isopentane, tissue samples were stored in a liquid nitrogen tank, while other biological materials, such as serum, were stored in a -80°C freezer.
Results: Tissue, plasma, serum, and DNA samples collected from patients with endocrine neoplasms were stored in separate barcoded storage boxes in the biobank and were made available to researchers.
Conclusion: The use of bioproducts in domestic research and international networks has strengthened research collaborations through supporting the collection and distribution of tissues, especially cancer tissues. This trend plays an important role in facilitating basic and applied research in various fields of cancer, including molecular biology, immunology, genetics and pharmacology, and will pave the way for scientific advances and therapeutic innovations.
