Abstract
Background and objectives: Meningitis is one of the most common infectious of the central nervous system (CNS), defined as an inflammation of the meninges. LIF is a potent pro-inflammatory factor. Cerebrospinal fluid (CSF) contains the growth factors and cytokines whose concentrations have been changed in most neurological diseases. The aim of this study was to determine the LIF concentration of serum and CSF in the children with bacterial meningitis.
Material and Methods: In this study, the total protein concentration (TPC) and LIF in the serum and CSF of normal subjects and children with bacterial meningitis were measured by enzyme linked immunosorbent assay (ELISA).
Results: the Values of serum TPC for children with meningitis (74.17±7.73 g/L) and controls (73.50±7.28 g/L) are not different significantly (P=0.7), and the TPC in the CSF of children suffering from meningitis and controls are 35±0.03 and 0.34±0.05 g/L, respectively (P=0.65). The concentration of serum LIF for children with meningitis( 253±19.14 ng/ml) is higher than that of controls (49.75±8.97 ng/ml), and also the concentration of LIF in the CSF of the children with meningitis (116.25±8.60 ng/ml ) is significantly higher than that of controls which is 9.04±1.83ng/ml (P<0.001).
Conclusion: The LIF concentration in the CSF and serum may provide additional information in the differential diagnosis of meningitis. It is also concluded that LIF could be significantly involved in the pathophysiology of meningitis.

Abstract
Background and Objective:Staphylococcusaureus is one of the important factors causing nosocomial infections. Typically 25-30 percent of healthy people carry the bacteria in their anterior nasal cavity. The physicians(50%), nurses (70%) and hospital staff (90%) are the carriers of this bacteria, leading to the infection of inpatients. The emergence of antibiotic-resistant Staphylococcus strains to vancomycin and methicillin has brought about several problems in treatment of the infections caused by Staphylococcus strains. Hence, we aimed to study the frequency of staphylococcus aureus carriers and resistance pattern among medical personnel of the surgical ward in ShahidRajaee hospital, Tonekabon.
Material and Methods: this analytic-descriptive study was conducted on the samples taken from nasal carriage of medical staff of surgical ward (N=120). Antibiotic- resistant of Staphylococcus strains was assessed by antibiogram and disk diffusion (DAD), in accordance with CLSI standards.
Results: of 34 (28.33%) who are nasal carriers of staphylococcus, 12 are over 30 years old and 24 under 30. Based on antibiogram, 1.97% of specimens are sensitive to Gentamicin and Co-trimoxazole, 1.94% to Ciprofloxacin, 2.88% to Vancomycin and 6.20% to Methicillin. In addition, 100% of specimens are resistant to Ampicillin, 1.97% to Penicillin and 2.88% to Amoxicillin. Four isolates areresistant,both to methicillin and vancomycin.
Conclusion:In this study, the spectrum of S. aureus resistant and sensitive strains to some antibiotics is similar to other studies, but a dramatic increase is seen in the rate of MRSA and non-susceptible cases to vancomycin. The Effectiveness of Penicillin, Amoxicillin and Ampicillin is still very low on S. aureus samples.

Abstract
Background and Objective: Much research has shown that Human Papiloma Virus (HPV) plays an important role in cervix cancer and it is the cause of 99% of cervix cancer worldwide. Lots of research has been done to find a proper method for HPV diagnosis and screening in patients with genital warts. This study aimed at comparing PCR method with Pap smear test in HPV screening.
Material and Methods: Considering the presence of DNA of HPV, 45 vaginal and cervix swap samples of women with genital warts were tested by means of specific PCR and Pap smear from September 2010 to April 2011.
Results: Out of 45 vaginal and cervix swap samples of women suffering genital warts, 37 samples (82.2%) are positive. Of 45 Pap smear samples, 13 (29%) are neoplasia and 32 (71%) normal.
Conclusion: The difference between the results of PCR and Pap smear is due to low specification and sensitivity of Pap smear. Thus it is recommended using diagnostic PCR method in addition to Pap smear in order to promote the quality of screening in individuals with genital warts.

Abstract
Background and objective: Antimicrobial and antiviral effects of Alloe Vera and Stachys inflata have been proved. We aimed to investigate the effects of extract of Alloe Vera and Stachys inflate on the growth of some bacteria to take the place of chemical drugs.
Material and Methods: the extracts of both plants were prepared by maceration method different concentrations were prepared using Mueller Hinton agar medium and tested by Disc diffusion. Furthermore, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by the Microdilution method.
Results: The effect of Alloe Vera extract was significant on Staphylococcus aureus. MIC and MBC of Aloe Vera extract on Bacillus subtilis were obtained in 230 and 410 mg/ml, respectively, which were 500 and 714 mg/ml for Haemophilus influenza. The extract of gel of Alloe Vera had no effect on Bacillus subtilis. The extract of leaf and gel of Alloe Vera had an inhibitory effect on Haemophilus influenza and Pseudomonads aeraginosa. The extract of Stachys inflata had an inhibitory effect on Haemophilus influenza, but it did not have any on Pseudomonads aeraginosa. The Extract of Stachys inflata had no effect on Bacillus subtilis, while showing significant effect on Staphylococcus. Among antibiotics, Ofloxacin had an effect on Haemophilus influenza. The extract of both plants did not show any effect on Klebsiella pneumonia.
Conclusion: Given the effect of Alloe Vera and Stachys inflata in laboratory conditions, we hope that these extracts will be used instead of chemical substances for making nutritional supplements to control human diseases.

Abstract
Abstract Background and Objective: Cryptosporidium is a common protozoan causing diarrhea in human, specifically in children. Hence, we aimed to investigate the prevalence of this protozoan among diarrheic children hospitalized in Gonbad Kavus in 2011. Material and Methods: Three stool samples were collected from diarrheic children in two hospitals of Gonbad city and a relevant questionnaire was filled out for each child. The stool samples were concentrated by formalin ether method, and the infection was assessed by modified acid-fast staining method. Results: Of 547 children, 27 (4.9%) were infected with cryptosporidiosis. There was no significant relationship between the amount of infection and gender and habitation area (urban/ rural). The infection rate was significantly prevalent in 2-4-year-old children (P=0.013). The most and the least infection rate were observed in spring and winter, respectively (P< 0.0001). There was a significant association between the disease and keeping animal (P= 0.041) Conclusion: The prevalence of cryptosporidiosis in diarrheic children in Gonbad is almost equal to other regions of the country and keeping animal and spring season may be considered as the risk factors for the disease.

Abstract
Background and Objective: This study aimed to investigate the antimicrobial susceptibility of the most common pathogens in hospitalized neonates in Intensive Care Unit.
Material and Methods: In this one-year descriptive study, 150 blood samples of neonates in Intensive Care Unit of Bahrami hospital of Tehran were divided into two groups of early onset sepsis (the first 72 hours of life) and late onset sepsis (after the 72 hours of life). After isolating and identifying of bacteria, their antibiotics susceptibility was studied by Kirby- bauer method in accordance with CLSI guidelines.
Result: The most isolated organisms were Klebsiella pneumoniae (41.3%). Coagulase negative staphylococcus was the cause of early onset septicemia and Klebsiella pneumoniae of both early and late onset septicemia. The highest susceptibility in gram-negative microorganisms was shown to Ciprofloxacin (89.6%) and in gram positive to Vancomycin (82.8%).
Conclusion: Gram-negative bacteria are the main cause of contamination in NICU and ciprofloxacin is the most effective antibiotic. Thus, it is imperative that NICU should be extremely controlled.

Abstract
ABSTRACT
Background and Objective: Several studies have
shown the antimicrobial activity of lactobacilli against Salmonella enterica (serotype typhimurium). The aim of this study was to evaluate the inhibitory potential of metabolites produced by probiotic culture of Lactobacillus casei against S. typhimurium and its impact on S. typhimurium motility and biofilm formation.
Methods: In order to evaluate the impact of the metabolites, L. casei cell-free culture supernatant (CFCS) was collected by centrifugation of L. casei secondary cultures. Effectiveness of the CFCS against Salmonella was evaluated by the well-diffusion method. In addition, in vitro effect of this treatment on motility in Swarm agar and biofilm formation by the bacteria was investigated.
Results: Inhibition zone diameters of S. typhimurium were 0.83 and 12.1 mm at concentrations of 50 and 100 μl of Lactobacillus CFCS against the log4 of S. typhimurium, respectively. Moreover, CFCS treatment inhibited the motility and biofilm formation by Salmonella. Concentrations of 5% and 10% were determined as the minimum inhibitory concentrations for motility and biofilm formation by S. typhimurium. Furthermore, effectiveness of the CFCS against Salmonella was dose-dependent (P<0.05).
Conclusion: L. casei CFCS is able to inhibit the growth, motility and biofilm formation in S. typhimurium.

Abstract
Background and objectives: Bacterial contamination of wounds is a serious problem, particularly in burn patients. Gram-positive bacteria are the predominant cause of infection in newly hospitalized burn cases. This study aimed to survey the prevalence and antibiotic resistance pattern of gram-positive bacterial isolates among burn patients in Rasht, North of Iran.
Methods: This cross-sectional study was conducted on burn patients with a positive culture for gram-positive isolates who were hospitalized in the Velayat Burn Center in Rasht, North of Iran, during 2017-2020. The isolates were identified using standard microbiological methods. Moreover, the antibiotic resistance pattern was determined by the disk diffusion method.
Results: During the study period, 671 bacterial cultures were obtained, of which a total of 16 gram-positive isolates were taken from the patients. The frequency of coagulase-negative staphylococci (CoNS), Staphylococcus aureus, and Enterococcus spp. was 68.7%, 18.8%, and 12.5%, respectively. In addition, the highest rate of resistance in CoNS isolates was against trimethoprim/sulfamethoxazole. The highest rate of resistant among S. aureus isolates was recorded against penicillin. Moreover, Enterococcus faecalis isolates showed a high level of resistance to ampicillin, erythromycin, tetracycline, gentamicin, and ciprofloxacin. All isolates were susceptible to teicoplanin. Moreover, the frequency of methicillin-resistant S. aureus isolates was 66.7%.
Conclusion: Given the increasing prevalence of drug-resistant strains, especially in susceptible burn patients, it is imperative to analyze the bacterial etiology of nosocomial infections periodically and epidemiologically.

Abstract
Background and objectives: Prolactin is a lactogenic protein hormone secreted by the anterior pituitary that initiates and maintains lactation in mammals. Previous research has linked increased serum prolactin levels to breast cancer. However, there is a paucity of studies in the Indian population on the subject. The present study evaluated and compared serum prolactin levels in patients with breast cancer and patients with benign breast diseases.
Methods: This cross-sectional, comparative study was carried out at the Government Medical College, Nagpur (India) on patients with breast diseases in the out-patient department/in-patient department from June 2018 to November 2020. Breast cancer patients were considered cases, and those with benign breast diseases were considered controls. Breast carcinoma diagnosis was based on clinical features, fine needle aspiration cytology, and tissue histopathology in operated specimens for each patient. Fasting serum prolactin levels were measured by the chemiluminescence immunoassay method using the Advia Centaur immunoassay system.
Results: There were 120 female patients with breast diseases, of whom 60 had breast malignancy, and 60 had benign breast diseases. The mean age of patients with benign breast disease and breast cancer was 33.17 (1.75) and 49.77 (1.16) years, respectively (P<0.0005). Increased serum prolactin levels were observed in 93.3% of patients with breast cancer and 13.3% of patients with benign breast diseases. The mean serum prolactin level was significantly higher among breast cancer patients (102.68±7.03) ng/ml compared with patients with benign breast disease (16.31±1.72 ng/ml). We successfully determined a new cut-off value of serum prolactin level (>40.2 ng/ml) to differentiate breast cancer from benign breast diseases using the receiver operating characteristic curve analysis.
Conclusion: Patients with breast cancer have increased serum prolactin levels compared to patients with benign breast diseases. Thus, serum prolactin level can be used as a diagnostic marker for breast cancer. This is particularly beneficial to clinicians for differentiating breast cancer from benign breast diseases.

Abstract
Background and objectives: The role of genetic components in expression of proteins involved in signaling pathways of fat and carbohydrate metabolism has been well-demonstrated. The aim of this study was to determine effects of high intensity interval training (HIIT) on glucose, insulin, and insulin resistance levels as well as IRS1 expression in gastrocnemius muscle of obese Wistar rats.
Methods: The study included 14 male, Wistar rats (aged 10 weeks) weighting 220 ± 20 g. Obesity was induced in all rats via exposure to a high-fat diet for six weeks. Then, the rats were randomly divided into a HIIT group (n=7) and a control group (n=7). The rats in the HIIT group performed treadmill running, five sessions a week, for eight weeks. Levels of fasting glucose, serum insulin, insulin resistance, and IRS1 expression in the gastrocnemius muscle of the rats were measured after the last training session. Data were analyzed by the independent t-test at statistical significance of 0.05.
Results: The HIIT intervention significantly decreased fasting glucose compared with the control group (p<0.0001). It also resulted in a significant decrease in serum insulin levels and insulin resistance compared with the control group (p<0.0001). Moreover, the HIIT training significantly increased IRS1 expression (p=0.030) in the gastrocnemius muscle of rats.
Conclusion: Based on the available evidence, the increase in insulin function and the decrease in insulin resistance can be attributed to increased IRS1 expression in the gastrocnemius muscle following HIIT training.

Abstract
Background and objectives: The outbreak of coronavirus disease 2019 (COVID-19) has become a global health emergency. The severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) NSP13 helicase plays an important role in SARS-CoV-2 replication and could serve as a target for the development of antivirals. The objective of the study was to perform homology modeling and docking analysis of SARS-CoV-2 NSP13 helicase as a drug target.
Methods: The structure and function of SARS-CoV-2 NSP13 helicase were predicted by in-silico modeling studies. The SWISS-MODEL structure assessment tool was used for homology modeling and visual analysis of the crystal structure of the protein. The validation for structure models was performed using PROCHECK. Model quality was estimated based on the QMEAN and ProSA. The MCULE-1-Click docking and InterEvDock-2.0 server were used for protein-ligand docking.
Results: The SARS-CoV-2 NSP13 helicase model corresponded to probability confirmation with 90.9% residue of the core section, which highlights the accuracy of the predicted model. ProSA Z-score of -9.17 indicated the good quality of the model. Inhibitor N-(3-(carbamoylamino) phenyl) acetamide exhibited effective binding affinity against the NSP13 helicase. The docking results revealed that Lys-146, Leu-147, Ile-151, Tyr-185, Lys-195, Tyr-224, Val-226, Leu-227, Ser-229 residues exhibit good binding interactions with inhibitor ligand N-(3-(carbamoyl amino) phenyl) acetamide.
Conclusion: Hence, the proposed inhibitor could potently inhibit SARS-CoV-2 NSP13 helicase, which is thought to play key roles during viral replication. The results of this study indicate that N-(3-(carbamoylamino) phenyl) acetamide could be a valuable lead molecule with great potential for SARS-CoV-2 NSP13 helicase inhibition.

Abstract
Background and objectives: Pandemics have serious adverse impacts on public health, economy, social structure, and overall growth and development of a nation. Such impacts can be mitigated by timely introduction of effective vaccination programs. This was successfully achieved in India. This study was performed to compare the anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) responses after first and second dose of coronavirus disease 2019 (COVID-19) vaccination.
Methods: This cross-sectional study included 60 people who were vaccinated with the AstraZeneca vaccine at Karnataka Institute of Medical Sciences, Hubballi, India. The subjects were divided into two groups. Group I included 30 people who had received a single dose of the vaccine, and group II included 30 people who had received two doses of the vaccine. Exclusion criteria included having a history of influenza like illness/severe acute respiratory infection/proven COVID-19 infection in past 6 months. The antibody response was measured by the Anti-SARS-CoV-2 IgG test using the VITROS Anti-SARS-CoV-2 IgG Reagent Pack.
Results: We observed that 97% of the subjects had reactive IgG antibodies after receiving two doses of the vaccine, whereas only 83% of the subjects developed antibodies after a single dose of the vaccine. A positive correlation was observed between the development of reactive antibodies and the duration between the first dose and the second dose (r=0.24).
Conclusion: Based on the results, the two-dose vaccination with the AstraZeneca vaccine is beneficial over the single-dose vaccination for protection against COVID-19. Moreover, increasing the duration between doses might improve the antibody response.

Abstract
Background and objectives: In patients with coronavirus disease 2019 (COVID-19), white blood cell (WBC) abnormalities have been found worldwide with significant inter-regional differences. In the present study, we evaluated WBC parameters concerning COVID-19 positivity and severity.
Methods: In this cross-sectional study, total WBC count, absolute count of each type of WBC, neutrophil to lymphocyte ratio (NLR), and lymphocyte to monocyte ratio (LMR) were compared between 150 COVID-19 patients and 150 non-COVID-19 patients presenting with COVID-19-like symptoms. Also, COVID-19 patients were divided into severe and non-severe cases.
Results: The severity of the disease had no significant association with age or gender (p>0.05). Total WBC count, absolute neutrophil count, absolute monocyte count, and NLR were significantly lower (p<0.05), while LMR was significantly higher in COVID-19 patients compared to non-COVID-19 patients (p<0.05). Total WBC count, absolute neutrophil count, and NLR were significantly higher (p<0.05), while absolute eosinophil count and absolute lymphocyte count were significantly lower (p<0.05) in severe COVID-19 patients compared to non-severe patients.
Conclusions: Age is not a predictive factor for the severity of COVID-19. Routine WBC parameters are useful in predicting the severity of the disease in COVID-19 patients and can be used as prognostic indicators. Routine WBC parameters can also be used for repeat RT-PCR testing in COVID-19 suspected patients.

Abstract
Background and objectives: Osteoporosis is a disease characterized by low bone mass and microarchitectural deterioration of bone tissue. It is the most common chronic metabolic bone disease. The purpose of this study was to compare the level of bone metabolic markers including parathyroid hormone (PTH), alkaline phosphatase (ALP), calcium, and phosphorus between female basketball players and non-athlete females.
Methods: Twelve female professional basketball players (aged 20-35 years) of the Super League of Golestan Province (Iran) were enrolled as the experimental group. Fifteen age-matched non-athlete females were also selected as the control group. Plasma levels of PTH, ALP, calcium, and phosphorus were compared between the study groups.
Results: The levels of PTH (p=0.004) and ALP (p=0.001) were significantly higher in the experimental group than in the control group. The levels of calcium and phosphorus did not differ significantly between the study groups (p>0.05).
Conclusion: Based on the results, it could be stated that performing weight-bearing sports activities such as basketball can improve the density of bone minerals and the factors stimulating bone formation.

Background: This study investigated the impact of a 3-week detraining period, followed by 10 weeks of aerobic training, on the serum levels of osteocalcin and alkaline phosphatase (ALP) in asthmatic males.
Methods: Thirty adult males with asthma were randomly divided into experimental and control groups. The experimental group engaged in a 10-week aerobic training program, which included running sessions 3 times per week for 30-60 minutes each, maintaining a target heart rate range of 55%-75% of their maximum heart rate (HRmax). In contrast, the control subjects did not participate in any exercise activities during the study period. Fasting blood samples were obtained at baseline, after aerobic training, and after detraining to measure the levels of osteocalcin and ALP in both groups.
Results: The 10-week aerobic training program led to a significant increase in levels of osteocalcin and ALP in the experimental group, but following the detraining period, these variables returned to their pre-training levels.
Conclusion: The effectiveness of continuous aerobic training on bone formation markers in asthmatic patients will disappear after a relatively short period of detraining. This evidence emphasizes the lack of stopping aerobic exercise in the presence of inhaled corticosteroids with the aim of improving bone metabolism in asthmatic patients.

Abstract
Background: The outcome of hospitalized COVID-19 patients is predictable according to demographic, clinical, laboratory, and imaging risk factors. We aimed to determine the best outcome predictors and their trends during 30 days of hospitalization.
Methods: This retrospective study was conducted on moderate to severe hospitalized COVID-19 patients from 26 January 2020 to 13 January 2021. The length of stay in the hospital was considered as the time interval between admission and discharge, and the patient's final condition was defined as either dead or alive. Demographic, clinical, and laboratory data were collected from the hospital information system. The generalized additive model and the Cox regression model were used to model data.
Results: Of the 1520 hospitalized COVID-19 patients, 232 (15.26%) died and 1288 survived or reached the end of 30 days of hospitalization. We selected demographic, clinical, and 131 independent laboratory variables. Blood urea nitrogen (BUN) had a nearly double average in the dead group (44.603 [± 25.408] mg/dL) than the survived group (21.304 [± 13.318] mg/dL), and the lymphocyte (Lymph) count showed the opposite trend. The estimated hazard ratio (HR) of these 2 factors was higher than 1 and was statistically significant. In daily stay trends, the hazard function of them also increased rapidly after 15 days.
Conclusion: Blood urea nitrogen and complete blood count provide strong predictive clues about the prognosis of hospitalized COVID-19 patients, and rapid dynamic changes in the second week can predict a poor outcome in these patients.

Abstract
Background: Intestinal infections with Helicobacter pylori mainly occur during childhood. If contracted, these infections may cause chronic gastritis, frequently leading to peptic ulcer disease in later life. This study aims to detect the prevalence of H. pylori infections in patients with active gastritis.
Methods: The study included 150 participants who were consuming daily anti-gastritis drugs to reduce the gas and were considered active gastritis patients and were recruited from Lekhnath 12, now known as Pokhara metropolitan-30, from May 2018 to March 2019. They were screened for H. pylori antibodies for detection of infection by the immunochromatographic rapid detection kit, and the data were analyzed using SPSS 2016.
Results: Serum anti-Helicobacter pylori antibodies were used to detect the presence of Helicobacter pylori in these participants. Among the 150 participants, 54 were males (36%) and 96 were females (64%). The results showed that 47 (31.3%) of the patients were positive for anti-Helicobacter pylori test. The age group 30 to 40 had the highest prevalence of 21 (14.0%). Using public water showed the highest prevalence with a P value of 0.04.
Conclusion: There should be an additional aspect required for the diagnosis and treatment of gastritis, which is the healthcare providers' and patients' awareness of the cause and most efficient treatments for this medical condition. Using only anti-gastritis drugs is not sufficient; treatment against Helicobacter pylori requires the right pathway of treatment by the use of several antibiotics.

Abstract
Background: The sputum smear-negative pulmonary tuberculosis (PTB) is a diagnostic challenge for physicians. It has been shown that adenosine deaminase (ADA) activity increases in various body fluids of patients with tuberculosis (TB). A prospective clinical trial was conducted to determine the effectiveness of ADA activity in bronchoalveolar lavage (BAL) in subjects who have sputum smear-negative PTB.
Methods: A total of 29 patients (M/F: 15/14), mean age (36.8 years), were enrolled in our study from October 2021 to August 2022 after providing written consent. The mean duration of symptoms was 41.66 days. Out of 29 patients, 21 patients had BAL ADA 4.81±1.68 unit??, for whom AKT treatment was started and cured, while four patients with BAL ADA 4.50±2.86 unit? did not improve, and four patients with BAL ADA 6.52±1.16 whose AKT treatment is ongoing at present but clinically improved. The sensitivity of BAL ADA with the outcome of 29 patients is 75%, while for BAL CBNAAT, it is 80%. When we apply a formula for combined sensitivity for the parallel test, then it comes to 95%, which indicates a great number of patients gets the benefit when we apply both tests simultaneously.
Results: We conclude that ADA activity was significantly increased in BAL.
Conclusion: BAL ADA is a useful and effective investigation for the diagnosis of PTB.
