Background and Objective: Health includes various dimensions, one of the most important of which is spiritual health. Although this aspect of health has a long history, it has attracted the attention of doctors and psychologists in the last few decades. One of the effective factors in spiritual health is rationality, which has always been one of the most controversial topics in the history of human thought. This study was done to explain the relationship between health and spirituality.

Methods: This research is of analytical-descriptive type, which was carried out using the library method and using verses, narrations and interpretive sources.

Results: Rationality is not only incompatible with spirituality but also strengthens it. The religion of Islam, which was descended for the development and growth of spiritual health, has always invited people to rationality and has condemned those who do not use reason and thought.

Conclusion: This study shows that rationality has a direct relationship with spirituality and causes the spiritual health of a person.

Background and Objective: Multiple sclerosis (MS) is an autoimmune disease that targets the central nervous system. Various studies have shown that several factors influence this disease’s occurrence and prevent its progress. Multiple studies have shown that several factors affect this disease’s occurrence and prevent its progress. Helicobacter pylori can be mentioned among these factors. This study was conducted to determine Helicobacter pylori infection in MS patients and healthy individuals.
Methods: This case-control study was conducted on 100 patients with MS (mean age: 36.99±9.87 years) and 100 healthy subjects (mean age: 38.05±11.38 years) in Golestan province, north of Iran during 2021. The case group included eighty relapsing-remitting cases and twenty secondary progressive cases. Blood samples were taken from both groups, and after separating the serum using the ELISA test, anti-Helicobacter pylori antibody (IgG) was detected by determining the antibody titer.
Results: Helicobacter pylori IgG in the MS and control groups was 21% and 44%, respectively (P<0.05). The mean concentration of IgG in the case group was significantly lower than the control group (13.48±10.83 versus 19.78±16.14 AU/ml). The percentage of positive cases of IgG antibody against Helicobacter pylori in the relapsing-remitting and secondary progressive group of patients with MS was determined as 21.2% and 20%, respectively, and the difference between these two groups was not statistically significant.
Conclusion: The history of Helicobacter pylori infection is less than two times in patients with MS compared to healthy people probably indicate the protective role of this bacterium against this disease.

Background and Objective: The diagnosis of inflammatory bowel disease (IBD) is performed by colonoscopy, sampling, and histopathology. Stool calprotectin is a test showing the presence of inflammation in the gastrointestinal tract. This study was done to determine the relationship between the calprotectin level in the feces and endoscopic findings in ulcerative colitis patients referred to the gastroenterology clinic in Gorgan, Iran.
Methods: This descriptive-analytical study was performed on 100 patients with ulcerative colitis referred to the gastroenterology clinic of Sayad Shirazi Hospital, Gorgan, north of Iran during 2020. The patients were asked to collect their stool samples one day before the procedure (just after taking the drug for bowel cleansing). Bowel cleansing was done by administering polyethylene glycol solution dissolved in water. The activity of ulcerative colitis was measured using the disease activity score. According to this criterion, a score greater than or equal to 5 is considered an active disease. Patients were classified into two groups: extensive or pan-colitis and left-sided colitis. Stool samples were evaluated for calprotectin in a single laboratory using a commercially available kit (Calprest- EuorociationspA. Trieste) at normal values of less than 50mg/g. The relationship between stool calprotectin with colonoscopic findings was evaluated.
Results: The average duration of infection was 4±3.1 years in the time range of 1-14 years. The calprotectin level was less than 50 μg/g in 16 patients. Stool calprotectin less than 50 µg/g was seen in only 16 patients. There was no significant relationship between the level of calprotectin and the either age or gender of patients. Most patients (84%) had active disease based on colonoscopic findings. Left-sided involvement was seen in 60% of patients. Fecal calprotectin level was significantly higher in those with acute phase and those with severe disease (P<0.05). Additionally, the calprotectin level had no significant relationship with the location of bowel involvement, extension, and disease duration.
Conclusion: This study showed that the fecal calprotectin level in patients with ulcerative colitis had a significant relationship with the severity and activity of the disease in north of Iran.

Background and Objective: Staphylococcus aureus is one of the most common causes of bacterial keratitis and conjunctivitis. This study was done to determine the efficacy of fluoroquinolones on Methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from external ocular infections.
Methods: This descriptive-analytical study was conducted on 187 pateiants (2 months to 61 years old) with symptoms of conjunctivitis and keratitis who were hospitalized or referred to the emergency department of hospitals in Golestan and Mazandaran provinces, Iran during 2020-22. The samples were taken from the external infection of the patients’ eyes. Methicillin-resistant Staphylococcus aureus isolates were identified by standard phenotypic microbiological and molecular detection (PCR) methods. The broth microdilution method determined sensitivity to quinolones and the minimum inhibitory concentration (MIC) in the 0.06-64 μg/ml range.
Results: The frequency of ocular MRSA isolates (n=52) was significantly higher in spring, females and patients aged 1-30 years (P<0.05). Among the MRSA isolates causing conjunctivitis, the highest rates of resistance were observed against ciprofloxacin (n=18, 48.64%), enoxacin (n=17, 45.95 %), and ofloxacin (n=17, 45.95%). The MIC of gemifloxacin that inhibited the growth of 90% of MRSA isolates from conjunctivitis (MIC90=0.25 μg/ml) was 32-fold lower than that of ciprofloxacin.
Conclusion: Depending on the season and age, staphylococcus aureus may be the most common cause of bacterial conjunctivitis and keratitis. Considering the in vitro antibacterial potential of gemifloxacin, this antibiotic can be used to treat the bacterial external eye infections.

Background and Objective: Nutritional knowledge can affect food choices and, as a result, sports performance. The study of nutritional knowledge, attitude, and performance in athletes can play a fundamental role in choosing the type of training and adapting suitable dietary interventions. This study was done to evaluate the knowledge, attitude, and nutritional performance of male bodybuilding athletes in Gorgan, Iran.
Methods: This descriptive-analytical study was done on 104 male bodybuilding athletes over 18 years old with a history of at least three months of continuous bodybuilding who were randomly selected from 13 bodybuilding clubs in Gorgan, Iran during 2020. Parmenter and Wardle’s standard questionnaire measured athletes’ nutritional knowledge, attitude, and performance. The questionnaire was completed by the athletes with the guidance of the researcher. A trained nutritionist collected anthropometric and body composition data using an Omron BF511 device.
Results: Poor nutritional knowledge, poor dietary attitude and poor nutritional performance was observed in 67.3%, 33.65% and 77.88% of the athletes respectively. A significant correlation was observed between nutritional knowledge with weight (r=0.23, P=0.02), BMI (r=0.27, P=0.01), and body fat percentage (r=0.22, P=0.02). Also A significant correlation was determined between nutritional performance with body weight (r=0.31, P<0.001), BMI (r=0.27, P<0.001), exercise time per week (r=0.22, P=0.02), and exercise timespan (r=0.32, P<0.001).
Conclusion: The level of knowledge, attitude, and nutritional performance of bodybuilding athletes was weak.

One of the main spermatogenesis events is the replacement of histones with small proteins called protamines, which leads to chromatin's condensation in the sperm nucleus and protects it against possible damage. Today, tests such as aniline blue (AB), toluidine blue (TB), and chromomycin A3 (CMA3) staining are used based on different characteristics to evaluate sperm chromatin compaction. For the assessment of DNA fragmentation in sperm, several tests such as 8-hydroxy-2-deoxyguanosine (8-OHdG), TUNEL, Comet, sperm chromatin structure assay (SCSA), sperm chromatic dispersion (SCD), and acridine orange have been introduced that directly and indirectly assay DNA damage. The articles in PubMed and Google Scholar, as well as related books, from 2007 to 2022, were collected and reviewed based on keywords 8-OHdG, TUNEL, Comet, SCD, and acridine orange. So far, many studies have been conducted at the treatment level and on sperm chromatin tests, but the number of cases published so far is limited. Various sperm samples have been used in different studies, with different threshold limits in the tests. The sixth edition of the World Health Organization (WHO) book notes that each laboratory has its threshold limit. Therefore, in this review study, common methods of evaluating chromatin packaging and DNA damage are introduced, and the advantages and disadvantages of each test are discussed based on the latest achievements related to infertility.

Background and Objective: Prostate cancer is a malignancy affecting men. Identifying risk factors for prostate cancer is crucial for the potential development of interventions and expanding our biological understanding of this disease. The present study investigated the association of rs1800896 and rs1800896 with prostate adenocarcinoma.
Methods: This case-control study was conducted on 176 men, including 78 patients with prostate adenocarcinoma (case group) and 98 men with benign prostatic hyperplasia (control group), who visited the Labafinejad Educational and Treatment Center in Tehran, Iran. Genotyping was performed using the Tetra ARMS-PCR (amplification refractory mutation system-polymerase chain reaction) method.
Results: There was no statistically significant difference between the case and control groups in the genotype frequency of rs1800896 and rs1465618. However, the rs1800896 polymorphism was associated with PSA levels less than or equal to 4 ng/mL (P<0.05). Significant associations were found between rs1800896 and rs1465618 polymorphisms and clinical features, such as perineural invasion (P<0.05).
Conclusion: The rs1800896 and rs1465618 polymorphisms were not associated with the risk of prostate adenocarcinoma.

Background and Objective: Silver nanoparticles are produced in large quantities in the industry and have estrogenic activities and toxic effects on different organs. This study was conducted to determine the effect of silver nanoparticles on the ovarian tissue of NMRI rats treated with alpha lipoic acid.
Methods: In this experimental study, 24 female NMRI rats were randomly divided into 4 groups of 6. The groups included the control group, oral silver nanoparticles (500 mg/kg of body weight), injected alpha lipoic acid (100 mg/kg of body weight), and silver nanoparticles (500 mg/kg of body weight) plus alpha lipoic acid (100 mg/kg body weight). The treatment was performed for 28 days. After the treatment period, blood sampling was performed from the rats’ hearts to analyze biochemical parameters (malondialdehyde, estrogen, progesterone, and total antioxidant capacity using the ferric reducing ability of plasma (FRAP) method). By dissecting the rats, the left ovaries were removed, fixed, molded, and cut, tissue passaging was performed, and the ovaries were stained using the hematoxylin-eosin method. Then, the ovarian tissue was evaluated by different stereological methods.
Results: The total mean ovarian volume, the cortex volume, the medulla volume, and the corpus luteum volume, and the total number of primordial, primary, secondary, and Graafian follicles were significantly reduced in the silver nanoparticles group compared to the control group (P<0.05). The simultaneous administration of alpha lipoic acid and silver nanoparticles compensated for the adverse effects of silver nanoparticles on the above parameters. On the other hand, the mean number of different types of follicles in the rats treated with alpha lipoic acid significantly increased compared to the control group (P<0.05). A statistically significant reduction was observed in the measurement of estrogen and progesterone hormones in the serum of the silver nanoparticles group compared to the control group (P<0.05). Moreover, in assessing the antioxidant capacity of the serum of the group treated simultaneously with silver nanoparticles + alpha lipoic acid, a statistically significant increase was observed compared to the group treated with silver nanoparticles (P<0.05).
Conclusion: Silver nanoparticles can have adverse effects on the structure of the ovary and its components, and alpha lipoic acid can largely compensate for these detrimental effects.

Background and Objective: Considering the increasing use of silver nanoparticles in various products, including industrial and medical products, serious worries have been created regarding the potential dangers of silver nanoparticles. This study was conducted to determine the effect of silver nanoparticles on the kidney tissues of quercetin-treated NMRI rats.
Methods: In this experimental study, 24 adult male NMRI rats were randomly divided into 4 groups of 6. The groups included the control group, the silver nanoparticles group (500 mg/kg/bw), the quercetin group (50 mg/kg/bw), and the silver nanoparticles (500 mg/kg/bw) + quercetin (50 mg/kg/bw) group. Silver nanoparticles were fed orally on a daily basis for 35 days. Quercetin was injected intraperitoneally on a daily basis for 42 days. At the end of the study, after taking blood from the rats, the dissection, tissue passaging, and Heidenhain’s Azan staining stages were carried out. The total volumes of the kidney, cortex and medulla, renal corpuscle, and glomerulus were evaluated by a stereological method. A qualitative assessment of apoptotic cells was performed using the tunnel method. The amount of malondialdehyde (MDA) in blood serum was specified as an indicator of lipid peroxidation by the Buege and Aust method.
Results: Comparing the body weight and kidneys, and the total kidney, cortex, and medulla volumes showed no statistically significant difference between the silver nanoparticles group and the control group. The silver nanoparticles group showed a significant increase in the total mean renal corpuscle volume, glomerular volume, tuft volume, Bowman’s capsule membrane volume, and the amount of MDA compared to the control group (P<0.05). Also, a statistically significant reduction was observed in the silver nanoparticles group in the total mean volume of Bowman’s capsule and capillary spaces compared to the control group (P<0.05). Quercetin could reduce the detrimental effects of silver nanoparticles on kidney cells as much as the control group; however, apoptosis was not shown in kidney cells in the group treated with quercetin. Assessing the cells in the silver nanoparticles group indicated the creation of apoptosis. The amount of serum MDA in the silver nanoparticles group showed a statistically significant increase compared to other groups (P<0.05).
Conclusion: The results of this study demonstrated that quercetin could reduce the detrimental effects of silver nanoparticles on kidney cells as much as the control group.

Background and Objective: The application of different nanoparticles using green synthesis is increasing due to fewer complications. This study was conducted to identify the effect of cobalt ferrite nanoparticles synthesized with sumac extract on changes in biochemical and histological factors in rats.
Methods: In this experimental study, 30 five-month-old male Wistar rats with an approximate weight of 250-300 mg/kg of body weight were divided into three groups: The control group (saline receiving), the experimental groups receiving intraperitoneal cobalt ferrite nanoparticles synthesized with sumac extract at a dose of 10 and 20 mg/kg of body weight. Serum and tissue samples (liver, kidney, and spleen) were isolated. Serum concentrations of urea, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatinine were determined. The photometric method was used to measure liver enzymes, the calorimetric method without omitting proteins based on the Jaffe method was used to measure creatinine, and the urease-glutamate dehydrogenase (GLDH) method was used to measure urea. Tissue samples were assessed by hematoxylin-eosin staining. Transmission electron microscopy (TEM) and scanning electron microscope (SEM) microscopic studies were used for microscopic investigations.
Results: No statistical significance was observed in blood samples and factors (urea, creatinine, ALT, and AST) in the experimental groups compared to the control group. Similarly, in the morphological investigation, the size of the liver, kidney, and spleen of the groups receiving cobalt ferrite nanoparticles synthesized with sumac extract was normal compared to the control group.
Conclusion: Cobalt ferrite nanoparticles synthesized with sumac had no toxic effect on the rats’ liver, spleen, and kidney tissues.

Background and Objective: Sinus extension is a physiological process that occurs in the growth cells of the paranasal sinuses and leads to increasing their volume over time, causing challenges in the dental implant process. This study was conducted to evaluate maxillary sinus morphometrics by cone-beam computed tomography (CBCT).
Methods: This descriptive-analytical study was conducted on the CBCT images of 100 people (52 male and 48 female) with a mean age of 45.32 ± 17.41 and the age range of 27 to 63 years referring to an oral and maxillofacial specialized radiology clinic in Babol, Iran during 2019. The amount of maxillary sinus extension in the panoramic-like view was recorded based on the amount of its extension in terms of the first anterior tooth and the last posterior tooth. In the new net technologies (NNT) software, in the section related to creating panoramic-like views, first, in the axial sections, the starting point of the maxillary sinus was specified from the occlusal side, and the mediolateral dimensions were measured at distances of 3 mm above and 3 mm below.
Results: The highest amount of maxillary sinus progress in the right anterior side was related to the mesial of tooth 5 (15%), and the highest amount of sinus progress in the left anterior side was related to the distal of tooth 3 (15%) and the mesial of tooth 4 (15%), which had no statistically significant differences. The most progress in the anterior area was related to the distal of the canine tooth and the mesial of the first premolar. The mean mediolateral sinus progress at 3 mm above the right nasal floor was higher in females than in males (P<0.05). Gender and age had no statistically significant relationship with maxillary sinus progress.
Conclusion: The maxillary sinus progress was almost equal in the left and right sides and also in males and females.

Background and Objective: In recent years, studies have been conducted to determine the prevalence rate of congenital abnormalities in different regions of Iran, most of which were conducted on live births. This study was conducted to determine fetal abnormalities in pregnancies leading to legal abortion in Golestan province.
Methods: This descriptive-analytical study was conducted on 199 pregnant women with a gestational age of less than 20 weeks with abortion licenses from the Forensic Medicine Center of Golestan province over 9 months during 2018-19. Demographic characteristics, including parents’ age, ethnicity, and family relationship, and the type of fetal abnormalities were recorded.
Results: Given 29,460 births in Golestan province over a 9-month period, the prevalence of fetal abnormalities was determined to be 6.75 per thousand births. The incidence rates of fetal abnormalities were determined to be 6.78, 6.68, 7.69, and 5.65 per thousand births in native Fars (80 cases), Turkmen (65 cases), Sistani (34 cases), and other (20 cases) ethnic groups, respectively. Since the gender of 80 fetuses was unknown, the incidence rates of abnormality were determined to be 4.36 and 3.72 per thousand births in female (63 cases) and male (56 cases) fetuses, respectively. The most common fetal abnormalities included central nervous system (n=49, 24.62%), chromosomal abnormalities (n=47, 23.61%), and cardiovascular impairments (n=26, 13.06%). The incidence of fetal abnormalities was not found to have a statistically significant relationship with parents' age, ethnicity, and family relationship.
Conclusion: The most prevalent fetal abnormality was related to central nervous system disorders. The incidence of fetal abnormalities had no relationship with the parents’ age, ethnicity, and family relationship.

Background and Objective: Bacterial nanocellulose is known as a potential carrier for a widespread spectrum of biological compounds, including antibacterial and antifungal compounds. The present study was conducted to determine the impact of bacterial nanocellulose containing Natamycin and Amphotericin B on Aspergillus flavus and Penicillium citrinum in an in vitro environment.
Methods: In this descriptive-analytical research, Aspergillus flavus-PTCC: 5006 and Penicillium citrinum-PTCC: 5304 fungi were prepared from the Fungal Collection of the Department of Microbiology, Faculty of Veterinary Medicine, Urmia University. The minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (MFC) of Natamycin and Amphotericin B against Aspergillus flavus and Penicillium citrinum were evaluated by the microdilution method. Bacterial nanocellulose was prepared using Komagata xylinum bacterium, and Natamycin and Amphotericin B were added in three concentrations of 0.01%, 0.05%, and 0.1% to wet and lyophilized nanocellulose films by the immersion method. Then, the antifungal effects of the film containing the above compounds against the investigated fungi were investigated by the agar diffusion method. Parchment paper was used as a control for comparison. Spectral properties of nanocellulose film containing antifungal compounds were evaluated by the Fourier transform infrared (FTIR) method.
Results: MIC and MFC of Natamycin for Aspergillus flavus were determined as 3.9 μg/mL and 7.81 μg/mL, and for Penicillium citrinum as 7.81 μg/mL and 15.62 μg/mL, respectively. MIC and MFC of Amphotericin B for Aspergillus flavus were determined as 7.81 μg/mL and 15.62 μg/mL, and for Penicillium citrinum as 15.62 μg/mL and 31.25 μg/mL, respectively. The increased concentration had a statistically significant impact on the antifungal properties of all films (P<0.05). The best antifungal effects of the film were related to the film containing Natamycin.
Conclusion: Bacterial nanocellulose containing Natamycin showed stronger antifungal effects in an in vitro environment compared to Amphotericin B against Aspergillus flavus and Penicillium citrinum.

Background and Objective: Periodontitis and rheumatoid arthritis are two chronic inflammatory diseases that are interrelated. Given the similarities between these conditions, the medications used by patients with rheumatoid arthritis (RA) may affect their periodontal indices. This study aimed to evaluate the periodontal index status in patients with RA undergoing immunosuppressive therapy.
Methods: This comparative cross-sectional study was conducted on 68 patients with RA in three treatment groups (20 on monotherapy, 24 on dual therapy, and 24 on triple treatment) and 20 healthy individuals with a plaque index (PI) below 35% in Ardabil, Iran during the second half of 2021. The monotherapy group included methotrexate or hydroxychloroquine; the dual therapy group included combinations of methotrexate with hydroxychloroquine, adalimumab, or infliximab; and the triple therapy group included combinations of methotrexate and hydroxychloroquine with adalimumab, etanercept, sulfasalazine, or leflunomide. Periodontal indices, including Plaque Index (PI), Clinical Attachment Loss (CAL), Gingival Index (GI), and Bleeding on Probing (BOP), were assessed.
Results: There were no statistically significant differences in periodontal indices among the three treatment groups (monotherapy, dual therapy, and triple therapy). The mean BOP index in the control group was significantly higher compared to the three medication groups (P<0.05). There were no statistically significant differences in the mean CAL and GI indices between the control group and the medication groups. The median PI in the control group was 29.6, and in the dual therapy group, it was 42.3, which was statistically significant (P<0.05).
Conclusion: The use of immunosuppressive drugs did not have a significant effect on the periodontal indices of patients with rheumatoid arthritis.

Renal cavernous hemangioma is a rare benign tumor. This case report describes a 44-year-old male who was incidentally found to have a renal mass during an abdominal and pelvic ultrasound. The patient's abdominal ultrasound revealed a mass, which was further evaluated with a CT scan. The CT findings suggested renal cell carcinoma. Suspecting malignancy, the patient underwent radical nephrectomy. Histopathological and immunohistochemical examinations ultimately diagnosed the mass as a cavernous hemangioma. Despite its benign nature, the patient was followed up with a control ultrasound three months post-surgery. This case is presented due to the significant clinical and radiological resemblance of this tumor to renal carcinomas, highlighting the importance of considering benign tumors in differential diagnoses.

Background and Objective: Colorectal cancer is the third most common cancer in men and the second most common in women. The use of parasites or parasite antigens is one of the newest therapeutic approaches for cancer, although it has not yet been used or approved in human trials. This study aimed to determine the cytotoxic effects of purified carbohydrates from the hyaline layer, fluid, and protoscolices of hydatid cysts on the human colorectal cancer cell line (LS174T).
Methods: This descriptive-analytical study was conducted on two sheep and two cow livers infected with hydatid cysts, and the human colorectal adenocarcinoma cell line (LS174T) purchased from the Pasteur Institute of Iran at the Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz, Iran during 2022. Cyst fluid, protoscolices, and the hyaline layer were isolated from the hydatid cyst-infected livers, and glycoproteins and glycolipids from different parts of the cyst were extracted using the chloroform-methanol method. Carbohydrates were purified using the beta-elimination method and their presence was confirmed using the phenol-sulfuric acid method. The cytotoxicity of purified carbohydrates on the LS174T cell line was evaluated using the methyl tetrazolium (MTT) assay for 24 hours.
Results: Concentrations of 0.5 and 0.25 of purified carbohydrates from glycoproteins and glycolipids of hydatid cysts significantly inhibited the growth of LS174T cells (P<0.05). Initial cytotoxicity evaluation showed that purified carbohydrates from glycoproteins of sheep cyst fluid (38.60±1.33%), glycoproteins of cow cyst hyaline layer (36.61±1.76%), glycolipids of cow cyst hyaline layer (38.94±2.99%), glycoproteins of cow cyst protoscolices (40.27±3.66%), and glycolipids of sheep cyst protoscolices (37.94±1.99%) had significantly more pronounced inhibitory effects (P<0.05). Subsequent screening with the MTT assay revealed that purified carbohydrates from glycoproteins isolated from sheep hydatid cyst fluid (52.35±10.24%), glycolipids isolated from cow hydatid cyst hyaline layer (53.40±7.88%), and glycolipids isolated from sheep hydatid cyst protoscolices (53.05±5.06%) had significantly more pronounced inhibitory effects on the growth of LS174T cancer cells (P<0.05).
Conclusion: Carbohydrates isolated from glycoproteins and glycolipids of the hyaline layer, fluid, and protoscolices of hydatid cysts have significant anticancer effects on the LS174T colorectal cancer cell line.
