Abstract
Recently discovered constituents of the brain waves-the oscillons -provide high-resolution representation of the extracellular field dynamics. Here we study the most robust, highest-amplitude oscillons that manifest in actively behaving rats and generally correspond to the traditional θ -waves. We show that the resemblances between θ -oscillons and the conventional θ -waves apply to the ballpark characteristics-mean frequencies, amplitudes, and bandwidths. In addition, both hippocampal and cortical oscillons exhibit a number of intricate, behavior-attuned, transient properties that suggest a new vantage point for understanding the θ -rhythms' structure, origins and functions. We demonstrate that oscillons are frequency-modulated waves, with speed-controlled parameters, embedded into a noise background. We also use a basic model of neuronal synchronization to contextualize and to interpret the observed phenomena. In particular, we argue that the synchronicity level in physiological networks is fairly weak and modulated by the animal's locomotion.

Abstract
Background People with multiple sclerosis (pwMS) on anti-CD20 therapies (aCD20) and fingolimod have shown inadequate humoral responses to COVID-19 vaccines. Objective The objective of the study was to pilot larger studies by demonstrating the safety and comparing the immunogenicity of different types of third doses in seronegative pwMS after two doses of BBIBP-CorV inactivated vaccine. Methods In December 2021, subject to receiving their third dose, being COVID-19-naiive, and receiving no corticosteroid within two months, we measured the level of anti-SARS-CoV-2-Spike IgG in pwMS seronegative after two shots of BBIBP-CorV inactivated vaccine. Results We included 20/29 pwMS who received adenoviral vector (AV), 7/29 who received inactivated, and 2/29 who received conjugated third doses. No serious adverse events were reported two weeks post-third dose. The pwMS receiving AV third doses showed significantly increased IgG concentrations, while only the ones not on aCD20 and fingolimod responded to inactivated third doses. An ordinal logistic multivariable generalized linear model indicated that age (per year β: -0.10, P = 0.04), type of disease-modifying therapy (aCD20 β: -8.36, P <0.01; fingolimod β: -8.63, P = 0.01; others: reference), and type of third dose (AV or conjugated β: 2.36, P = 0.02; inactivated: reference) are predictive of third dose immunogenicity among pwMS who remain seronegative after two shots of BBIBP-CorV vaccine. Statistical significance was not achieved for variables sex, MS duration, EDSS, duration of DMT, duration of third dose to IgG test, and duration from last aCD20 infusion to third dose. Conclusion This preliminary pilot study highlights the need for further research to determine the optimal COVID-19 third dose vaccination strategy for pwMS living in areas where BBIBP-CorV vaccine has been used.

Abstract
Cancer is caused by abnormal proliferation of cells and aberrant recognition of the immune system. According to recent studies, natural products are most likely to be effective at preventing cancer without causing any noticeable complications. Among the bioactive flavonoids found in fruits and vegetables, quercetin is known for its anti-inflammatory, antioxidant, and anticancer properties. This review aims to highlight the potential therapeutic effects of quercetin on some different types of cancers including blood, lung and prostate cancers.

Abstract
Background Various studies indicated blunted humoral responses to COVID-19 mRNA and viral vector vaccines among people with multiple sclerosis (pwMS) on sphingosine 1-phosphate receptor (S1PR) modulators and anti-CD20 therapies (aCD20); however, limited evidence was found regarding SARS-CoV-2 serology after inactivated virus vaccination. Objective To provide evidence regarding humoral response to COVID-19 inactivated virus vaccination among pwMS on disease-modifying therapies (DMTs). Methods A cohort study was carried out in Isfahan, Iran, enrolling DMT-exposed pwMS and unexposed (UX) healthy participants. Post-vaccination anti-SARS-CoV-2 Spike IgG serology testing was carried out among the participants and compared between participants based on their DMT exposure, using proper statistical tests. A multivariable logistic regression model was used to control for confounding. Association between the second vaccine dose-to-phlebotomy (vac2phleb) and the humoral response was investigated in each DMT-exposed cohort, using linear regression. Among the aCD20 cohort, the association of the last aCD20 infusion-to-first vaccine dose period with serostatus was investigated using an unpaired t-test. Results After enrolling 358 participants (144 pwMS and 214 healthy), blunted humoral responses were only observed in fingolimod (Log10 mean diff. [SE]: 0.72 [0.18], P = 0.001) and aCD20 (Log10 mean diff. [SE]: 0.75 [0.15], P < 0.001) cohorts compared to the UX cohort. Multivariable analysis confirmed the results. The study did not achieve enough statistical power to detect a significant association between the vac2phleb period and humoral responses. The last aCD20 infusion to first vaccination dose period was longer in the seroconverted pwMS on aCD20 (mean diff. [SE]: 8.43 weeks [2.57], P = 0.005). Conclusion The results of this study mirrored the results of previous studies among mRNA- or viral vector-vaccinated pwMS on DMTs. Therefore, it can be concluded that mode of action contributes less than timing, to the efficiency of vaccination strategies among pwMS on DMTs – especially the ones on S1PR modulators and aCD20. Meanwhile, the mentioned pwMS should be advised to receive early boosters and remain vigilant until further data becomes available and more efficient vaccination strategies are crafted.

Abstract
The failure of immunological tolerance to self-antigens plays a fundamental role in the pathogenesis of systemic lupus erythematosus (SLE). PD-1 is an inhibitory receptor for regulating the immune system and preventing development of autoimmune disorders. This study aimed to determine the role of four single-nucleotide polymorphisms (SNPs) within programmed cell death 1 (PDCD1 or PD-1) gene and haplotypes defined by these SNPs in susceptibility to SLE in the Iranian population. Blood samples were obtained from 253 SLE and 564 healthy subjects. Red blood cells were lysed and genomic DNAs were extracted using salting-out method. Genotype determinations of PD1.1, PD1.3, PD1.5 and PD1.9 SNPs were performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and 12 haplotypes were constructed by PDCD1 SNPs. Our results showed significant differences in PD1.5 genotype frequencies between patient and control groups (p < .001). The frequencies of PD1.5 C/C, C/T and T/T genotypes versus other genotypes in SLE patients significantly differed from healthy subjects (p < .001, p = .001 and p = .002, respectively). Allelic analysis indicated a significant association between the frequency of PD1.5C allele and development of SLE in our population (odds ratio [OR] = 1.91, 95% confidence interval [CI] = 1.51-2.42, p < .001). At the haplotype level, GGCC, GACT and GGCT haplotypes were significantly different between SLE and control groups (OR = 2.14, 95% CI = 1.73-2.66, p < .001; OR = 9.76, 95% CI = 4.47-21.3, p < .001; and OR = 0.32, 95% CI = 0.24-0.42, p < .001, respectively). Based on these findings, PD1.5 SNP and some haplotypes of PDCD1 contribute to SLE risk in the Iranian population.

Abstract
Granulocyte-macrophage colony-stimulating factor (GM-CSF) was first described as a growth factor that induces the differentiation and proliferation of myeloid progenitors in the bone marrow. GM-CSF also has an important cytokine effect in chronic inflammatory diseases by stimulating the activation and migration of myeloid cells to inflammation sites, promoting survival of target cells and stimulating the renewal of effector granulocytes and macrophages. Because of these pro-cellular effects, an imbalance in GM-CSF production/signaling may lead to harmful inflammatory conditions. In this context, GM-CSF has a pathogenic role in autoimmune diseases that are dependent on cellular immune responses such as multiple sclerosis (MS) and rheumatoid arthritis (RA). Conversely, a protective role has also been described in other autoimmune diseases where humoral responses are detrimental such as myasthenia gravis (MG), Hashimoto's thyroiditis (HT), inflammatory bowel disease (IBD), and systemic lupus erythematosus (SLE). In this review, we aimed for a comprehensive analysis of literature data on the multiple roles of GM-CSF in autoimmue diseases and possible therapeutic strategies that target GM-CSF production.

Abstract
BACKGROUND Cardiovascular diseases are the highest ranking cause of mortality. The prevalence of cardiovascular diseases is increasing among people in developed and developing countries. Since left ventricular hypertrophy is one of the risk factors leading to extremely dangerous heart diseases and even sudden death at early ages, investigating its contributing factors can be beneficial. The purpose of this study was to determine factors contributing to left ventricular hypertrophy in students aged 7-18 years in Isfahan. Statistical population of this case-control study was the 7-18 year old students in Isfahan, who were studied in two groups of children with premature myocardial infarction in their parents and the control group. MATERIALS AND METHODS After determining the sample size of 138 people, a two-part questionnaire was designed and demographic characteristics and anthropometric measures were recorded in students' profiles. The obtained information was analyzed using SPSS15 software and logistic regression model and the results were reported at P < 0.05. RESULT The results showed that among the studied variables, gender, age, body mass index, and blood pressure were associated with the left ventricular hypertrophy. CONCLUSION Considering the results and previous studies in this field, it was observed that left ventricular hypertrophy exists at early ages, which is very dangerous and can lead to heart diseases at early ages. Factors such as being overweight, having high blood pressure, and being male cause left ventricular hypertrophy and lead to undiagnosable heart diseases.

Abstract
OBJECTIVES Clinical laboratory health care workers can become infected through their occupation with blood-borne pathogens by percutanous injuries and mucocutaneous blood contacts such as cuts, needle sticks, splashes to mucous membranes or other body injuries. The purpose of this study was to determine the seroprevalence of, Hepatitis C virus (HCV), and some of the risk factors in medical laboratory health care workers. METHODS Through a descriptive cross sectional study, 203 participants employed in the clinical laboratories of the city of Isfahan, composed of medical laboratory technologists, technicians and cleaning staff were studied. Participant data were obtained through a self-reporting questionnaire and the level of anti-HCV antibody was measured by enzyme linked immunosorbent assay (ELISA). Chi-square test was used to determine risk factors associated with infection. RESULTS The mean age of the individuals (n = 203) was 35.8 ± 9.54 years. There were 115 women (56.7%) and 88 men (43.3%). All of the subjects were negative for HCV Ab. CONCLUSIONS Hepatitis C infection is infrequent in laboratory health care workers in Isfahan province.

Abstract
Four cases of acrogeria in one large family with multiple consanguineous marriages are reported. Inheritance is autosomal recessive. Evaluation of six generations of this family also showed six individuals with congenital blindness; this pedigree suggests autosomal recessive inheritance also for this disorder. Association of the two conditions was not seen in living members. The initial presentation in the patients with acrogeria was failure of growth during the first year of life, accompanied by characteristic facial appearance and cutaneous atrophy of the face and extremities. The radiologic features of these patients were acro-osteolysis, wide sutures and fontanelles, wormian bones, mandibular hypoplasia and avascular necrosis of the femoral heads. Other features were osteolysis of the clavicles, soft tissue calcification, osteoporosis and coxa valga, which have not been described in previous reported cases.

Abstract
With improved operative technique and postoperative care, progressively older patients are being referred for cardiac surgery. One hundred out of 633 patients operated between September 1990 and December 1992, were over 75 years of age (Group I). These patients were compared with the last 100 patients under 75 years of age (Group II). Both groups were operated by the same surgical team with the same anaesthetic, cardiopulmonary bypass and myocardial protection techniques. The average age of the groups was 79.5 +/- 3.1 and 62.1 +/- 9.2 years, respectively. The procedures performed were: myocardial revascularisation (Group I, 28 cases; Group II, 59 cases), aortic valve surgery alone or associated with coronary bypass (56 and 22 cases respectively), and mitral valve surgery alone or associated with another procedure (11 and 12 cases). There were no significant differences between the two groups with respect to true low output state, the duration of mechanical ventilation and of intensive care and hospital stay. On the other hand, there were significant differences in: the number of blood transfusions (44 cases versus 20, p < 0.001), the occurrence of atrial fibrillation (52 cases versus 29, p < 0.001) and neuropsychiatric disturbances (27 cases versus 5, p < 0.0001). There were no cases of mediastinitis in either group. The hospital mortality was 6% in Group I and 5% in Group II (NS). The medium-term mortality after an interval of 5 to 32 months in the over 75 age group was 7 cases, including 4 cases of cerebrovascular accident. An enquiry was performed in the 87 survivors of Group I.(ABSTRACT TRUNCATED AT 250 WORDS)
