Obesity and its associated disorders, such as hyperlipidemia, have become a global issue following the consumption of unhealthy, high-fat, and high-carbohydrate foods, which burdens the economies and the health systems of human societies worldwide. This study aimed to evaluate the effect of oral consumption of 6- gingerol and L-arginine supplements on obesity factors. Thirty rats in five groups were fed a diet specific to each group for 12 weeks and then treated with the oral administration of L-arginine (200 mg/day) and 6-gingerol (100 mg/day) for 12 weeks. The food and water intake and weight change, were then measured. In addition, plasma glucose, triglyceride, cholesterol, high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and serum hormone levels, including corticosterone, testosterone, and insulin, were measured, and NPY, Y1, and Y5 receptor gene expression were recorded using real-time PCR. Administration of 6-gingerol and L-arginine decreased food intake, weight gain, glucose levels, insulin levels, and homeostasis model assessment-insulin resistance (HOMA-IR) index compared to the HCD control group. In addition, corticosterone and testosterone levels in the study groups showed a significant decrease (P<0.05) and increase (P<0.01) compared to the control groups, respectively. Triglyceride, total cholesterol, HDL, and VLDL levels in the groups treated with L-arginine and gingerol alone or combined significantly decreased compared to the control group (P<0.01). This study confirms that 6-gingerol and L-arginine supplements prevent HCD-induced hyperlipidemia by controlling hormones and neurotransmitters involved in the general metabolism.

Nonlinear self-modulation of dust-ion acoustic (DIA) waves is studied in an unmagnetized dusty plasma comprising warm adiabatic ions, arbitrarily charged dust particles, and hot nonextensive q-distributed electrons. By employing the multiple space and time scales perturbation, a nonlinear Schrodinger equation is derived for the evolution of the wave amplitude. The existence along with the stability of wave packets are discussed in the parameter space of two oppositely charged dust and ion temperature over different ranges of the nonextensive parameter q. The growth rate of the modulation instability is also given for different values of the q parameter. It is found that the critical wave number at which the instability sets in increases as the nonextensive parameter q increases. This leads to a wider range (in spatial extension) of the stable envelope solitons. It is also found that the effects of ion temperature and negative (positive) dust concentration significantly modify the criteria for the modulation instability of DIA waves. Our finding should elucidate the nonlinear electrostatic structures that propagate in astrophysical and cosmological plasma scenarios where nonextensive particles exist: such as instellar plasma, stellar polytropes, cosmic radiation, and systems with long-rang interaction. PACS Nos.: 52.27.LW, 52.35.FP, 52.35.MW. Nous etudions l'auto-modulation non lineaire d'ondes de poussiere-ion (DIA) dans un plasma poussiereux non magnetise comprenant des ions chauffes adiabatiquement, des particules de poussiere arbitraires et des electrons chauds a distribution q non extensive. En employant la methode de perturbation a echelles de temps et a espaces multiples, nous obtenons une equation de Schrodinger non lineaire pour decrire revolution de l'amplitude de l'onde. Nous etudions l'existence et la stabilite des paquets d'onde dans l'espace de parametre de la temperature et des charges opposees de la poussiere et des ions, sur differents domaines du parametre non extensif q. Nous presentons egalement le taux de croissance de l'instabilite de modulation pour differentes valeurs du parametre q. Nous trouvons que le nombre d'onde critique ou commence l'instabilite croit avec le parametre non extensif q. Ceci permet un plus grand domaine en extension spatiale pour l'enveloppe stable de solitons. Nous trouvons egalement que les effets de la temperature ionique et de la concentration de poussiere negative (positive) modifient significativement les criteres pour l'instabilite de modulation des ondes DIA. Nos resultats devraient expliquer les structures electrostatiques non lineaires qui se propagent dans les scenarios cosmologiques et astrophysiques dans lesquels on trouve des particules non extensives : comme les plasmas interstellaires, les polytropes stellaires, les radiations cosmiques et les systemes avec interaction a longue portee.

Because of the mutual relationship between neural inflammation and seizure, this study aimed to determine the effects of intracerebroventricular (ICV) injection of the steroidal and non-steroidal anti-inflammatory drugs on pentylenetetrazol (PTZ)-induced seizures during the estrous cycle in rats. A total of 105 adult female Wistar rats were selected and divided into seven groups, including the control (saline), ketorolac tris salt (7.5, 15, and 30 µg), and methylprednisolone acetate (0.15, 0.3, and 0.6 µg), each with four subgroups (proestrus, estrus, metestrus, and diestrus) and three replicates (n=5). After a week of acclimatization, the estrous phase determination and synchronization were performed. Acute epilepsy was inspired by the intraperitoneal injection of 80 mg/kg of PTZ 30 min after the ICV injection of ketorolac and methylprednisolone acetate. The initiation time of myoclonic seizures (ITMS), the initiation time of tonic-clonic seizures (ITTS), seizure duration (SD), and mortality rate (MR) were measured for 30 min. Data were shown as mean±SD and analyzed using One-way ANOVA followed by Tukey-Kramer multiple comparison post hoc test (P<0.05). According to the results, ketorolac (15 and 30 µg) and methylprednisolone acetate (0.3 and 0.6 µg) significantly increased the ITTS and ITMS but decreased SD during the estrous cycle, compared to the control (P<0.05). Moreover, MR and SD were significantly decreased by ketorolac (7.5, 15, and 30 µg) and methylprednisolone (0.3 and 0.6 µg), compared to the control during the estrous cycle (P<0.05). Therefore, it seems that both ketorolac and methylprednisolone possess dose-dependent anticonvulsant effects that may decrease neural inflammation. [ABSTRACT FROM AUTHOR]

Antibiotic resistance is among the most concerning issues worldwide. Currently, the use of natural alternatives with improved therapeutic effects and fewer complications than common therapies is considered a novel therapeutic approach to care urinary tract infections (UTI). In this research, we evaluated the prospective activity of Oliveria decumbens vent essential oil (ODEO) in the treatment of Escherichia coli-induced cystitis. The antibacterial properties of ODEO were investigated using standard microdilution assays against E. coli. To induce cystitis, 1.5 ×108 CFU/ml of E. coli (ATCC 700928) was injected into the bladder of Wistar rats, and then they were prescribed ODEO and gentamicin. The histopathological parameters of the bladders were tested at the end of the study. The MIC and MBC of the ODEO against E.coli were 0.54 μl/ml and 1.024 μl/ml respectively. In the infected group with no treatment, the infiltration of inflammatory cells and the thickness of bladder tissue were increased notably, however in the groups treated with ODEO, especially at higher doses, the parameters were significantly decreased (p<0.01). The ODEO efficacy was comparable to gentamicin in the reduction of the bacterial count. In addition, after administration of the ODEO, inflammation, fibrosis, and thickness of epithelium also decreased in a dosedependent manner (p<0.01). In conclusion, treatment with ODEO which added as drinking supplement or injected subcutaneously resulted to the renal clearance of pathogens in study rats. [ABSTRACT FROM AUTHOR]

It is known that phoenixin-14 (PNX-14) has a mediatory role in reproduction; however, there is no report on the role of the PNX-14 on epilepsy. Therefore, this study aimed to investigate the antiepileptic effects of the PNX-14 on the pentylenetetrazol (PTZ)-induced epilepsy in the stages of the estrous cycle among rats. A total of 168 adult female Wistar rats were randomly divided into seven groups, including control (intracerebroventricular injection was performed with saline), PNX-14 (5 µg), PNX-14 (10 µg), bicuculline (competitive antagonist of GABAA receptors; 5 nmol)+PNX-14 (5 µg), bicuculline (BIC) (5 nmol)+PNX-14 (10 µg), saclofen (competitive antagonist of GABAB receptors; 2.5 µg)+PNX-14 (5 µg), and saclofen (2.5 µg)+PNX-14 (10 µg) in proestrus, estrus, metestrus, and diestrus. Afterward, the control and treatment groups were followed by intraperitoneal administration of 80 mg/kg PTZ. Initiation time of myoclonic seizures (ITMS), initiation time of tonic-clonic seizures (ITTS), seizure duration (SD), and mortality rate (MR) were monitored and recorded for 30 min. According to the results, PNX-14 alone significantly reduced the SD and seizure mortality in all phases of estrus (P<0.05). The injection of PNX-14 with BIC significantly reduced SD and seizure mortality in all estrus phases (P<0.05). PNX-14 alone increased both ITMS and ITTS in all phases of estrus (P<0.05). Furthermore, the injection of PNX-14 with BIC significantly reduced the effects of the PNX-14 on ITMS and ITTS in all estrus stages (P<0.05). These results showed that the antiepileptic activity of PNX-14 was probably mediated by GABAA receptors, and this effect was more prominent during the luteal phase than the follicular phase.

Haemonchosis is one of the most important parasitic diseases of the gastrointestinal tract of small ruminants in different parts of Iran and worldwide. While the disease poses major economic problems in the livestock industry, there are many reports on parasites' resistance to benzimidazoles necessitating to study of the level of this drug resistance in pathogens. The aim of this study was to evaluate the drug resistance of Haemonchus contortus to benzimidazole using molecular method in sheep from the North region of Iran. In this study, the resistance to benzimidazole was investigated using the PCR-RFLP method in the nematode Haemonchus contortus from sheep slaughtered in the northern region of Iran (Gilan and Mazandaran provinces). The samples examined in this study were evaluated between April 2020 and September 2021 from a total of 2400 sheep by determining the age groups of <2 years, 2>4 years, and >4 years. Three hundred Haemonchus contortus nematodes were randomly selected and investigated by means of PCR-RFLP and using TaaI endonuclease enzyme (SNP) in the beta-tubulin gene, responsible for drug resistance of Haemonchus contortus to benzimidazole. Haemonchus contortus was found in 66.8% and 60.5% of sheep in Gilan and Mazandaran. The results of the study showed that the drug sensitivity rate was 24% (72/300), the drug resistance rate was 54% (162/300) and 22% (66/300) of the samples had both resistant and sensitive alleles. Presented data showed a high level of prevalence of drug resistance in the nematode Haemonchus contortus in sheep in the northern region of Iran, which requires special attention to control the development of this resistance and the epidemic of haemonchosis in ruminants.

Background: Adequate dietary consumption of calcium is crucial in the preservation of bone health and the prevention of osteoporosis. This study investigated the prevalence of insufficient dietary calcium intake among individuals aged ≥50 years in Iran., Methods: We analyzed data from the Iranian Multicenter Osteoporosis Study (IMOS-2021). Participants aged 50 years and older completed a 168-item food frequency questionnaire. Insufficient dietary calcium intake was characterized as a daily calcium intake of <1000 mg for men aged 50-70 years, and <1200 mg for men over 70 years and women over 50 years and older. Stata v17 statistical software facilitated a survey set analysis to estimate the population's mean and median dietary calcium intake and the prevalence of insufficient dietary calcium intake., Results: The study included 1450 participants with a mean age of 60.7±7.9 years. The estimated mean dietary calcium intake in Iran was 1062.7 mg/day (95% CI: 1029.6-1095.8), with a median intake of 943.5 mg/d (95% CI: 910.5-976.4). The prevalence of insufficient dietary calcium intake in Iran was estimated to be 62.9% (95% CI: 60.0%-65.7%). Notably, the prevalence was higher among women at 75.5% (95% CI: 71.9%-78.8%), compared to men at 47.8% (95% CI: 43.4%-52.3%) with a significant difference (P<0.001). In age-related findings, individuals aged 65 years and older had a higher prevalence of insufficient intake, at 69.0% (95% CI: 63.9%-74.0%), versus those under 65 years, at 60.3% (95% CI: 56.9%-63.8%), with this difference being statistically significant (P = 0.007). Furthermore, a significant inverse relationship was identified between both educational years and socioeconomic status and the prevalence of insufficient dietary calcium intake (Ps for trends<0.001)., Conclusion: Our findings revealed a significant prevalence of insufficient dietary calcium intake in women and those aged 65 and older. We advocate for targeted public health strategies to ensure sufficient dietary calcium intake across these populations., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Ghazbani et al.

Background & Objective: Osteoporosis is a growing public health concern, particularly among the aging population. This study aimed to evaluate the association between osteoporosis and quality of life (QoL) in a sample of older adults., Methods: This cross-sectional study utilized data from all the participants of Bushehr Elderly Health program (BEHP), phase 2. QoL was assessed using the 12-Item Short Form Survey (SF-12 Questionnaire), and participants were classified as having osteoporosis or not based on the WHO diagnostic criteria. The physical (PCS) and mental (MCS) component summaries of QoL were estimated. The association between osteoporosis and QoL was evaluated separately for men and women, considering various health and lifestyle factors using linear regression analysis., Results: The study included 2,399 participants (average age 71.27 ± 7.36 years). 1,246 were women and 1,153 were men. Osteoporosis was present in 59% of women and 23% of men. Participants with osteoporosis had significantly lower PCS scores compared to those without osteoporosis (women: 38.1 vs. 40.2, p < 0.001; men: 44.3 vs. 45.8, p: 0.002). However, there was no statistically significant difference in MCS scores. Stratified by sex, osteoporosis was significantly associated with PCS in women [β = -2.14 (-3.13, -1.15)] and men [β = -1.53 (-2.52, -0.54)]. After accounting for relevant variables, the association remained significant in women [β=-0.95 (-1.87, -0.03)], but not in men [β=-0.63 (-1.55,0.28)]., Conclusion: This study highlights the significant association between osteoporosis and the physical component of QoL in both older men and women, particularly among women. Further research and interventions focusing on enhancing physical QoL in individuals with osteoporosis are warranted to promote healthier aging., (© 2024. The Author(s).)

Neural EGFL like 1 (NELL-1), is a secreted glycoprotein and stimulates osteogenic cell differentiation and bone mineralization. This study aimed to explore the relationship between NELL-1 and Trabecular Bone Score (TBS) as a novel tool for the evaluation of osteoporosis in an elderly population-based cohort study in Iran. A single-locus analysis was performed on TBS using data from 2,071 participants in the Bushehr Elderly Health (BEH) Program. The study investigated 376 independent single nucleotide polymorphisms (SNPs) within the NELL-1 on chromosome 11p15.1. The association between SNPs and the mean TBS L1 to L4 was analyzed through an additive model. Significant variants in the additive model (PFDR<0.05) were further examined within dominant, recessive, over-dominant, and co-dominant models. Multiple linear regression was employed to assess the relationship between the genetic risk score (GRS) derived from significant SNPs and TBS. Three SNPs within the NELL-1 showed a statistically significant association with TBS after adjusting for age and sex. The associations for rs1901945 (β = 0.013, PFDR = 0.0007), rs1584851 (β = -0.011, PFDR = 0.0003), and rs58028601 (β = 0.011, PFDR = 0.0003) were significant in the additive model. Additionally, significant results were observed for rs1901945 and rs58028601 in the dominant model (P<0.05). The GRS showed a statistically significant relationship with TBS, considering adjustments for age, sex, Body Mass Index, type 2 diabetes, and smoking (β = 0.077, P = 1.7×10-5). This study highlights the association of NELL-1 with TBS, underscoring its potential as a candidate for further research and personalized medicine concerning the impact of this gene on bone quality., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Bidkhori et al.

Background and Objective: Considering the importance of diabetes and its increased prevalence with aging, this study aimed to evaluate the association between diabetes status and quality of life (QOL) and the determining factors in individuals over 60., Methods: Two thousand three hundred seventy-five individuals including 819 (34.5%) with diabetes, aged 69.4 ± 6.4, from Bushehr Elderly Health Program (BEHP) were enrolled. We categorized the participants as non-diabetic, controlled diabetic, and poorly controlled diabetic. The QOL was assessed using the SF-12 questionnaire. The physical (PCS) and mental (MCS) component summaries of QOL were estimated. We compared the SF-12 domains and components between the categories using ANOVA. Further, the association of diabetes status with PCS and MCS was assessed after adjustment for possible confounders including age, sex, depression, cognitive impairment, physical activity, and other relevant factors using linear regression analysis., Results: Individuals with diabetes had lower PCS (40.9 ± 8.8 vs. 42.7 ± 8.6, p-value < 0.001), and MCS scores (45.0 ± 10.2 vs. 46.4 ± 9.4, p-value < 0.001) compared to participants without diabetes. No significant differences were observed in PCS or MCS scores between controlled or poorly controlled individuals with diabetes. Diabetes status was associated with PCS and MCS scores in univariable analysis. Regarding physical component of QOL, after adjusting for other confounders, poorly controlled diabetes was significantly associated with PCS [beta: -1.27 (-2.02, -0.52)]; some other determinants include depression [-7.66 (-8.51, -6.80)], male sex [3.90 (3.24,4.57)], and good physical activity [1.87 (1.17,2.57)]. As for the mental component, controlled diabetes was significantly associated with MCS [-1.17 (-2.13, -0.22)]; other contributing factors include depression [-14.35 (-15.34, -13.37)], male sex [1.97 (1.20,2.73)], good physical activity [-1.55 (-2.35, -0.75)], and smoking [-1.42 (-2.24, -0.59)]. BMI had an inverse association with PCS [-0.19 (-0.26, -0.13)] and a direct association with MCS [0.14 (0.07,0.21)]., Conclusion: Individuals with diabetes exhibited reduced QOL scores. Upon adjusting for other variables, it was found that uncontrolled diabetes correlated with decreased PCS scores, whereas controlled diabetes was linked to lower MCS scores. Factors such as depression and being female were identified as contributors to diminished QOL in both physical and mental aspects. These results have the potential to guide healthcare decision-making, facilitating the creation of tailored interventions aimed at improving the QOL for individuals with diabetes, with a specific focus on women and depression., (© 2024.

Purpose: The Discovery of underlying intermediates associated with the development of dyslipidemia results in a better understanding of pathophysiology of dyslipidemia and their modification will be a promising preventive and therapeutic strategy for the management of dyslipidemia., Methods: The entire dataset was selected from the Surveillance of Risk Factors of Noncommunicable Diseases (NCDs) in 30 provinces of Iran (STEPs 2016 Country report in Iran) that included 1200 subjects and was stratified into four binary classes with normal and abnormal cases based on their levels of triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and non-HDL-C.Plasma concentrations of 20 amino acids and 30 acylcarnitines in each class of dyslipidemia were evaluated using Tandem mass spectrometry. Then, these attributes, along with baseline characteristics data, were used to check whether machine learning (ML) algorithms could classify cases and controls., Results: Our ML framework accurately predicts TG binary classes. Among the models tested, the SVM model stood out, performing slightly better with an AUC of 0.81 and a standard deviation of test accuracy at 0.04. Consequently, it was chosen as the optimal model for TG classification. Moreover, the findings showed that alanine, phenylalanine, methionine, C3, C14:2, and C16 had great power in differentiating patients with high TG from normal TG controls. Conclusions: The comprehensive output of this work, along with sex-specific attributes, will improve our understanding of the underlying intermediates involved in dyslipidemia., Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-024-01384-9., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s), under exclusive licence to Tehran University of Medical Sciences 2024.

Obesity and its associated disorders, such as hyperlipidemia, have become a ‎global issue following the consumption of unhealthy, high-fat, and high-‎carbohydrate foods, which burdens the economies and the ‎health systems of human societies worldwide. This study aimed to evaluate ‎the effect of oral consumption of 6-gingerol and L-arginine supplements on obesity factors. Thirty rats in five groups were fed a diet specific to each ‎group for 12 weeks and then treated with the oral administration of L-arginine (200 mg/day) and 6-gingerol (100 mg/day) for 12 weeks. The food and water ‎intake and weight change, were then measured. In addition, plasma glucose, ‎triglyceride, cholesterol, high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL)‎, low-density ‎lipoprotein (LDL), and serum hormone levels, including corticosterone, testosterone, and insulin, were measured, and NPY, Y1, and Y5 receptor gene expression were recorded using real-time PCR. Administration of 6-gingerol and L-arginine decreased food intake, ‎weight gain, glucose levels, insulin levels, and homeostasis model assessment-insulin resistance (HOMA-IR) index compared to ‎the HCD control group. In addition, corticosterone and testosterone levels in the ‎study groups showed a significant decrease ( P <0.05) and increase ( P <0.01) compared to the control groups, respectively.

Objectives: Obesity is a metabolic syndrome that leads to many chronic diseases worldwide. In this study, we investigate the antihyperlipidemic activities of chitosan nanoparticles (CH NPs) on silymarin (SIL) as a carrier in the drug delivery system that can improve some biochemical parameters and hormones in the model of hyperlipidemic rats receiving a high-fat diet (HFD)., Materials and Methods: Physicochemical characterization of silymarin-loaded chitosannanoparticles (CH-SIL NPs) was done by Fourier-transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), and drug loading efficiency (LE). Diet-induced hyperlipidemic rats were treated with SIL (15 mg/kg/day) and CH-SIL NPs(15 mg/kg/day) for twelve weeks orally daily. The body weight loss (BW), food consumption, serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), levels of fasting blood glucose (FBG) in serum, serum insulin, cortisol, testosterone, and brain neuropeptide Y (NPY), Y1 and Y5 receptor mRNA expression were analyzed., Results: A significant reduction in BW and food consumption from 417 ± 16 g and 33 ± 1.03 in group HFD to 338 ± 10 g and 17.33 ± 1.02 in group CHS+HFD was observed, respectively. This data revealed that CH-SIL NPs improved hyperlipidemia, hyperinsulinemia, and hyperglycemia, reduced serum cortisol, and down-regulated NPY and Y1R with a significant increase in HDL and testosterone hormones compared to the control group., Conclusion: The developed Sil-loaded CH NPs were good agents for improving efficacy. It is the first report of the proposed weight loss mechanism of SIL CH NPs, thereby providing information about the anti-hyperlipidemic and antihyperglycemic effects of silymarin-loaded chitosan nanoparticles, a natural food with proper effects against metabolic disorders in case of hyperlipidemia that may lead to obesity and up-regulation of brain NPY., Competing Interests: The authors declare no conflicts of interest.

Alzheimer's disease (AD) is a neurodegenerative disorder that leads to cognitive decline and memory loss. Unfortunately, there is no effective treatment for this condition, so there is a growing interest in developing new anti-AD agents. In this research project, a series of phenyl-quinoline derivatives were designed as potential anti-AD agents. These derivatives were substituted at two different positions on benzyl and phenyl rings. The structures of the derivatives were characterized using techniques such as IR spectroscopy, 1 H NMR, 13 C NMR, and elemental analysis. During the in vitro screening, the derivatives were tested against both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). It was observed that most of the derivatives showed higher selectivity against BChE compared to AChE. Among the derivatives, analog 7n (with a methoxy group at R 1 and a 4-bromine substituent at R 2 exhibited the highest potency, with a 75-fold improvement in the activity compared to the positive control. Importantly, this potent analog demonstrated no toxicity at the tested concentration on SH-SY5Y cells, indicating its potential as a safe anti-AD agent. The level of GSK-3β was also reduced after treatments with 7n at 50 μM. Overall, this study highlights the design and evaluation of phenyl-quinoline derivatives as promising candidates for developing novel anti-AD agents., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Background: Population aging is a pervasive phenomenon occurring rapidly worldwide, while sustainable development goals are considered the mental health among older adults., Methods: To investigate the factors affecting mental health, we conducted a scoping review of the 47 papers published between 2015 and 2022 to explore various dimensions affecting older adults' mental health., Results: Our finding mirrors four dimensions of creating healthy and sustainable environments for older adults: person, place, processes, and resilience-related health in the living environment. The person dimension includes individual characteristics, attitudes and behaviors, and health status. The place dimension is divided into five categories: land use, access, physical form, public open spaces, and housing, while the process consists of the social, cultural, and economic environments. Resilience-related health dimension emphasizes the impact of natural and man-made disasters on older people's mental health., Discussion: These findings can provide policymakers insights into developing community-based environmental intervention strategies to promote mental health among older adults and support healthy and active aging., (© 2023.

Objective: Polycystic ovary syndrome (PCOS) is a common multifactorial endocrine disorder affecting women of reproductive age. ACE enzyme is involved in the physiopathology of the ovarian system, and there are inconsistencies between studies regarding the association between ACE gene variants and PCOS. The objective of this study is to evaluate the association between ACE I/D gene polymorphisms and PCOS, as well as its clinical manifestations, in Iranian women with PCOS., Design: This study included 140 patients with PCOS and 153 controls without the disease. Samples were collected from Yas Hospital Complex in Tehran-Iran during 2018 to 2022. Genomic DNA was obtained from whole blood samples using salt extraction, and genotyping was carried out using polymerase chain reaction (PCR)., Results: Variants of DD, ID, and II were observed in 31.4, 44.3, and 24.3% of PCOS, and 38.6, 44.1, and 17.2% of control group, respectively. The frequency of ACE gene variants did not differ between PCOS patients and control group. A significant difference was observed between the frequency of elevated LH to FSH ratio > 2 and ACE gene polymorphisms in patients with PCOS (OR: 0.32 (0.12-0.88), P value 0.024) with lower frequency observed in D allele carriers., Conclusion: This study indicate that although ACE I/D variants frequency in PCOS women is similar to non-PCOS women, it may be involved in the pathogenesis of the disease through mechanisms regulating steroidogenesis in the ovary and suggests that ACE might be related to exacerbated clinical manifestations of PCOS which requires further investigations., Competing Interests: Conflict of interestThe authors declare no conflict of interest., (© The Author(s), under exclusive licence to Tehran University of Medical Sciences 2023.

Background: The risk of depression among patients with diabetes is higher than the general population. The exact mechanisms linking these two diseases are mostly unknown. Energy metabolism disorders seem to be a shared pathway. One of the key genes playing important roles in energy metabolism-related pathways is the APOE gene. We aimed to investigate the association of the APOE gene variants with depression among Iranian patients with type 2 diabetes (T2DM)., Methods: Three APOE gene alleles and genotypes frequencies (E2, E3, E4) were determined in 244 patients with T2DM (114 with depression and 130 without depression) using the high-resolution melting (HRM) method on the genomic DNA extracted from the patient's peripheral blood., Results: Apoe4 allele frequency was significantly higher in T2DM patients without depression compared with those with depression (11.9 vs. 2.2%, p-value < 0.0001 and p-value = 0.001, respectively). Conversely, the wild allele apoe3 frequency was significantly higher in T2DM patients with depression (86% vs., 69%, p-value < 0.0001). Apoe4 carrier status was associated with decreased risk of depression in patients with T2DM [OR: 0.19 (0.07-0.53)]., Conclusion: Our results showed that the apoe4 allele and apoe4 carrier status significantly reduced the risk of depression among patients with T2DM. Further studies are needed to unravel the complex role of the APOE gene in depression among patients with diabetes., Competing Interests: Conflict of interestNone., (© The Author(s), under exclusive licence to Tehran University of Medical Sciences 2023.

The study investigated the wound healing potential of Piascledine (an avocado/soybean mixture) alone and in combination with bacterial nanocellulose on rat cutaneous wounds. Full-thickness excisional wounds (2 cm in diameter) were induced on the backs of 60 Sprague-Dawley rats, divided into four groups, treated with daily topical application of bacterial nanocellulose (BNC), Piascledine 10% (PSD 10%) and Piascledine+bacterial nanocellulose (PSD + BNC) (10 mg/disk) and normal saline (control) for 20 days. Wounds were monitored daily, and at 10, 20 and 30 days post-injury (DPI), tissue samples were collected for biochemical, histopathological and molecular analyses. Treated rats with PSD and PSD + BNC showed a significant decrease in the wound area compared with other groups. PSD and particularly PSD + BNC modulated inflammation, improved fibroplasia and angiogenesis and scar tissue formation at short term. At the long term, they reduced the scar tissue size and improved collagen fibres alignment, tissue organization and remodelling as well as re-epithelialization. PSD enhanced matrix metalloproteinase-3 (MMP-3) gene expression, collagen and glycosaminoglycans (GAGs) synthesis and decreased tissue inhibitor of metalloproteinase-1 (TIMP-1) gene expression at various stages of wound healing. The study concluded that topical application of Piascledine, particularly in combination with bacterial nanocellulose, promotes wound healing activity by modulating inflammation, regulating MMP-3 expression and enhancing collagen and GAGs synthesis., (© 2023 The Authors.

Background: We aimed to document the current state of exposure to low bone mineral density (BMD) and trends in attributable burdens between 2000 and 2019 globally and in different World Health Organization (WHO) regions using the Global Burden of Disease (GBD) study 2019., Methods: We reviewed the sex-region-specific summary exposure value (SEV) of low BMD and the all-ages numbers and age-standardized rates of disability-adjusted life years (DALYs), years lived with disability (YLDs), years of life lost (YLLs), and deaths attributed to low BMD. We compared different WHO regions (Africa, the Eastern Mediterranean Region, Europe, Region of the Americas, Southeast Asia, and Western Pacific), age categories, and sexes according to the estimates of the GBD 2019 report., Results: The global age-standardized SEV of low BMD is estimated to be 20.7% in women and 11.3% in men in 2019. Among the WHO regions, Africa had the highest age-standardized SEV of low BMD in women (28.8% (95% uncertainty interval 22.0-36.3)) and men (16.8% (11.5-23.8)). The lowest SEV was observed in Europe in both women (14.7% (9.9-21.0)) and men (8.0% (4.3-13.4)). An improving trend in the global rate of DALY, death, and YLL was observed during 2000-2019 (-5.7%, -4.7%, and -11.9% change, respectively); however, the absolute numbers increased with the highest increase observed in global YLD (70.9%) and death numbers (67.6%). Southeast Asia Region had the highest age-standardized rates of DALY (303.4 (249.2-357.2)), death (10.6 (8.5-12.3)), YLD (133.5 (96.9-177.3)), and YLL (170.0 (139-197.7))., Conclusions: Overall, the highest-burden attributed to low BMD was observed in the Southeast Asia Region. Knowledge of the SEV of low BMD and the attributed burden can increase the awareness of healthcare decision-makers to adopt appropriate strategies for early screening, and also strategies to prevent falls and fragility fractures and their consequent morbidity and mortality.

Background and Purpose: P-glycoprotein (P-gp) is an adenosine triphosphate (ATP)-dependent membrane efflux pump for protecting cells against xenobiotic compounds. Unfortunately, overexpressed P-gp in neoplastic cells prevents cell entry of numerous chemotherapeutic agents leading to multidrug resistance (MDR). MDR cells may be re-sensitized to chemotherapeutic drugs via P-gp inhibition/modulation. Side effects of synthetic P-gp inhibitors encouraged the development of natural products., Experimental Approach: Molecular docking and density functional theory (DFT) calculations were used as fast and accurate computational methods to explore a structure binding relationship of some dietary phytochemicals inside distinctive P-gp binding sites (modulatory/inhibitory). For this purpose, top-scored docked conformations were subjected to per-residue energy decomposition analysis in the B3LYP level of theory with a 6-31g (d, p) basis set by Gaussian98 package., Findings/results: Consecutive application of computational techniques revealed binding modes/affinities of nutritive phytochemicals within dominant binding sites of P-gp. Blind docking scores for best-ranked compounds were superior to verapamil and rhodamine-123. Pairwise amino acid decomposition of superior docked conformations revealed Tyr303 as an important P-gp binding residue. DFT-based induced polarization analysis revealed major electrostatic fluctuations at the atomistic level and confirmed larger effects for amino acids with energy-favored binding interactions. Conformational analysis exhibited that auraptene and 7,4',7'',4'''-tetra- O -methylamentoflavone might not necessarily interact to P-gp binding sites through minimum energy conformations., Conclusion and Implications: Although there are still many hurdles to overcome, obtained results may propose a few nutritive phytochemicals as potential P-gp binding agents. Moreover; top-scored derivatives may have the chance to exhibit tumor chemo-sensitizing effects., Competing Interests: The authors declared no conflict of interest in this study., (Copyright: © 2023 Research in Pharmaceutical Sciences.)

Objectives: Intolerable side effects and resistance to chemotherapeutic drugs have encouraged scientists to develop new methods of drug combinations with fewer complications. This study aimed to investigate the synergistic effects of quercetin and imatinib encapsulated in chitosan nanoparticles on cytotoxicity, apoptosis, and cell growth of the K562 cell line., Materials and Methods: Imatinib and quercetin were encapsulated in chitosan nanoparticles and their physical properties were determined using standard methods and SEM microscope images. BCR-ABL positive K562 cells were cultured in a cell culture medium, cytotoxicity of drugs was determined by MTT assay and the effects of nano drugs on apoptosis in cells were investigated by Annexin V-FITC staining. The expression level of genes associated with apoptosis in cells was measured by real-time PCR., Results: The IC 50 for the combination of the nano drugs at 24 and 48 hr was 9.324 and 10.86 μg/ml, respectively. The data indicated that the encapsulated form of drugs induced apoptosis more effectively than the free form ( P <0.05). Moreover, the synergistic effect of nano drugs in statistical analysis was proved ( P =0.001). The combination of nano drugs resulted in the caspase 3, 8, and TP53 genes upregulation ( P =0.001)., Conclusion: The results of the present study showed that the encapsulated form of imatinib and quercetin nano drugs with chitosan has more cytotoxicity than the free form of the drugs. In addition, the combination of imatinib and quercetin as a nano-drug complex has a synergistic effect on the induction of apoptosis in imatinib-resistant K562 cells., Competing Interests: The authors declare no conflict of interest.

Background: Evidence, albeit with conflicting results, has suggested that cardiometabolic risk factors, including obesity, type 2 diabetes (T2D), dyslipidemia, and hypertension, are highly associated with changes in metabolic signature, especially plasma amino acids and acylcarnitines levels. Here, we aimed to evaluate the association of circulating levels of amino acids and acylcarnitines with metabolic syndrome (MetS) and its components in Iranian adults., Methods: This cross-sectional study was performed on 1192 participants from the large-scale cross-sectional study of Surveillance of Risk Factors of non-communicable diseases (NCDs) in Iran (STEP 2016). The circulating levels of amino acids and acylcarnitines were measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS) in individuals with MetS (n=529) and without MetS (n=663)., Results: The higher plasma levels of branched-chain amino acids (Val, Leu), aromatic amino acids (Phe, Tyr), Pro, Ala, Glu, and the ratio of Asp to Asn were significantly associated with MetS, whereas lower circulating levels of Gly, Ser, His, Asn, and citrulline were significantly associated with MetS. As for plasma levels of free carnitine and acylcarnitines, higher levels of short-chain acylcarnitines (C2, C3, C4DC), free carnitine (C0), and long-chain acylcarnitines (C16, C18OH) were significantly associated with MetS. Principal component analysis (PCA) showed that factor 3 (Tyr, Leu, Val, Met, Trp, Phe, Thr) [OR:1.165, 95% CI: 1.121-1.210, P<0.001], factor 7 (C0, C3, C4) [OR:1.257, 95% CI: 1.150-1.374, P<0.001], factor 8 (Gly, Ser) [OR:0.718, 95% CI: 0.651-0.793, P< 0.001], factor 9 (Ala, Pro, C4DC) [OR:1.883, 95% CI: 1.669-2.124, P<0.001], factor 10 (Glu, Asp, C18:2OH) [OR:1.132, 95% CI: 1.032-1.242, P= 0.009], factor 11 (citrulline, ornithine) [OR:0.862, 95% CI: 0.778-0.955, P= 0.004] and 13 (C18OH, C18:1 OH) [OR: 1.242, 95% CI: 1.042-1.480, P= 0.016] were independently correlated with metabolic syndrome., Conclusion: Change in amino acid, and acylcarnitines profiles were seen in patients with MetS. Moreover, the alteration in the circulating levels of amino acids and acylcarnitines is along with an increase in MetS component number. It also seems that amino acid and acylcarnitines profiles can provide valuable information on evaluating and monitoring MetS risk. However, further studies are needed to establish this concept., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Taghizadeh, Emamgholipour, Hosseinkhani, Arjmand, Rezaei, Dilmaghani-Marand, Ghasemi, Panahi, Dehghanbanadaki, Ghodssi-Ghassemabadi, Najjar, Asadi, khoshniat, Larijani and Razi.)

Aim: This paper presented the methodology and main findings of a population-based survey to determine diabetes care status among type 2 diabetic subjects in Iran. The current study assessed treatment goal achievements in type 2 diabetics, diabetes care service utilization, prevalence of diabetes complications, and psychological effects of diabetes in a representative sample of Iranian population in urban and rural areas., Materials and Methods: This nationwide study was conducted between 2018 and 2020 as the observational survey entitled "Diabetes Care (DiaCare)". We studied a representative sample of participants with type 2 diabetes, aged 35-75 years, living in urban and rural areas in all thirty- one provinces of Iran. Data were collected by an interviewer in a form of a questionnaire that includes demographic and socioeconomic status, family and drug history, lifestyle, and self-reported psychological status according to a Patient's Health Questionnaire (PHQ). Management goal achievements, diabetes care service utilization, diabetes complications and psychological effects of diabetes were also assessed. Physical measurements were measured based on standard protocol. Fasting blood glucose (FBG), HbA1c, lipid profile, and also urine albumin to creatinine ratio were obtained from all participants of the study., Results: Overall, 13,334 people with type 2 diabetes in 31 provinces of Iran completed the survey (response rate: 99.6%). In total 13,321 participants, 6683(50.17%) women and 6638(49.83%) men were included in our analysis. Thirteen recruited patients refused after the consenting process and did not respond. The mean age (SD) of total participants was 54.86 ± 9.44 years and 71.50% were from the urban areas. 13.66% of diabetic patients had achieved the triple target of management [controlled HbA1c, blood pressure, and Low-Density Lipoprotein-Cholesterol (LDL-C)] in the whole country. While 28.74% of people had controlled HbA1c and 33.40% of them had controlled FBG. Diabetic subjects living in rural areas had less controlled HbA1c (23.93 vs. 29.48), controlled FBG (29.50 vs. 34.20) and controlled triple targets (10.45 vs. 14.32) than those living in urban areas. Diabetic neuropathy and diabetic foot were more common in women than men, while end-stage of renal disease (ESRD) was more common in men than women., Conclusions: This population-based study provided representative information about diabetes care in Iran. The high prevalence of diabetes and low proportion of diabetes control in Iran implies that it is necessary to identify factors associated with poor treatment goal achievements. Besides, general improvements in management and care of diabetes are mandatory., Competing Interests: Conflict of interestAuthors declare that they have no conflict of interest., (© The Author(s), under exclusive licence to Tehran University of Medical Sciences 2022.

Background: This paper presents the protocol of the 4 th round of Iranian Multi-center Osteoporosis Study (IMOS), a national survey with the primary objective of estimating the prevalence of osteoporosis and sarcopenia and their risk factors in a representative sample of urban and rural populations., Methods: The target population of the survey is all individuals ≥ 50 years in Iran. A multi-stage random sampling method has been used in the study. We stratified the 31 provinces of the country into 5 strata based on the distribution of their potential risk factors for osteoporosis and randomly selected one or two provinces from each stratum. Then, we invited 2530 people aged ≥ 50 years recruited in the 8 th National Survey of None Communicable Diseases (NCD) Risk Factors (STEPs-2021) in the selected provinces to participate in IMOS. Body composition measurements including bone mineral density, muscle mass, and fat mass are measured through Dual-energy X-ray Absorptiometry (DXA) method using HOLOGIC (Discovery and Horizon) devices; and Trabecular Bone Score (TBS) is measured on the DXA scans using iNsight software. Anthropometric measurement and physical examinations are made by a trained nurses and other required information are collected through face-to-face interviews made by trained nurses. Laboratory measurements are made in a central lab. The prevalence of osteoporosis and sarcopenia will be estimated after applying sampling design, non-response, and post-stratification weights to the data., Discussion: IMOS will provide valuable information on the prevalence and determinants of osteoporosis and sarcopenia at the national level, and the results can be used in evaluating health system interventions and policymaking in the field of musculoskeletal diseases., (© 2022.

Purpose: This study aimed to evaluate the performance of valid risk assessment models developed for osteoporosis/ fracture screening to identify women in need of bone density measurement in a population of Iranian elderly women., Methods: This study was performed using the data of Bushehr Elderly Health (BEH) program, a population-based cohort study of elderly population aged ≥ 60 years. Seven osteoporosis risk assessment tools, including Osteoporosis Risk Assessment Instrument (ORAI), Malaysian Osteoporosis Screening Tool (MOST), Osteoporosis Prescreening Risk Assessment (OPERA), Osteoporosis Prescreening Model for Iranian Postmenopausal women (OPMIP), Osteoporosis Index of Risk (OSIRIS), and Osteoporosis Self-Assessment Tool for Asians (OSTA), as well as Fracture Risk Assessment Tool (FRAX) were included in the study. By using osteoporosis definition based on BMD results, the performance measurement criteria of diagnostic tests such as sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Youden index for each model were calculated and the models were compared., Results: A total of 1237 female participants with the mean age of 69.1 ± 6.3 years were included. Overall, 733 (59%) participants had osteoporosis, and about 80% had no history of fracture. The sensitivity of the seven models ranged from 16.7% (OSIRIS) to 100% (ORAI and MOST) at their recommended cut-off points. Moreover,their specificity ranged from 0.0% (ORAI and MOST) to 78.9% (OSTA). The FRAX and OPERA had the optimal performance with the Youden index of 0.237 and 0.226, respectively. Moreover, after combining these models, the sensitivity of them increased to 85.4%., Conclusion: We found that the FRAX (model with 11 simple variables) and OPERA (model with 5 simple variables) had the best performance. By combining the models, the performance of each was improved. Further studies are needed to adopt the model and to find the best cut-off point in the Iranian postmenopausal women., Competing Interests: Competing interestsThe authors declare no competing interest., (© The Author(s), under exclusive licence to Tehran University of Medical Sciences 2022, Springer Nature or its licensor holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Introduction and Objectives: Amino acids are the most frequently reported metabolites associated with low bone mineral density (BMD) in metabolomics studies. We aimed to evaluate the association between amino acid metabolic profile and bone indices in the elderly population., Methods: 400 individuals were randomly selected from 2384 elderly men and women over 60 years participating in the second stage of the Bushehr elderly health (BEH) program, a population-based prospective cohort study that is being conducted in Bushehr, a southern province of Iran. Frozen plasma samples were used to measure 29 amino acid and derivatives metabolites using the UPLC-MS/MS-based targeted metabolomics platform. We conducted Elastic net regression analysis to detect the metabolites associated with BMD of different sites and lumbar spine trabecular bone score, and also to examine the ability of the measured metabolites to differentiate osteoporosis., Results: We adjusted the analysis for possible confounders (age, BMI, diabetes, smoking, physical activity, vitamin D level, and sex). Valine, leucine, isoleucine, and alanine in women and tryptophan in men were the most important amino acids inversely associated with osteoporosis (OR range from 0.77 to 0.89). Sarcosine, followed by tyrosine, asparagine, alpha aminobutyric acid, and ADMA in women and glutamine in men and when both women and men were considered together were the most discriminating amino acids detected in individuals with osteoporosis (OR range from 1.15 to 1.31)., Conclusion: We found several amino acid metabolites associated with possible bone status in elderly individuals. Further studies are required to evaluate the utility of these metabolites as clinical biomarkers for osteoporosis prediction and their effect on bone health as dietary supplements., (© 2022.

Phoenixin-14‎ (PNX‎-14‎) is a newly identified neuropeptide with potential anti-inflammatory effects in the gastrointestinal tract. In this study, we evaluated the protective effect of PNX-14 against the formation of experimental indomethacin (IND)-induced duodenal ulcer. Thirty-two‎ male Sprague-Dawley rats were randomly assigned to the four following study groups: (1) negative control (2) IND (7.5 mg/kg subcutaneous IND), (3) famotidine (FA) (7.5 mg/kg subcutaneous IND followed by 40 mg/kg intraperitoneal‎ FA), and (4) PNX-14 (7.5 mg/kg subcutaneous IND followed by 50 µ/kg intraperitoneal‎ PNX-14). Outcome measures included macroscopic evaluation of duodenal lesion, serum levels of IL-1ß, TNF-α, IL-6, and IL-12, and tissue biochemical parameters of oxidative stress, including malondialdehyde (MDA)‎‏,‏‎ myeloperoxidase ‎‎(MPO) activity, superoxide dismutase (SOD) ‎activity, and catalase activity. Results The macroscopic grade of duodenal lesions were significantly smaller in the PNX-14 group than in the IND group (p < 0.001). Serum inflammatory cytokines were significantly increased in the IND group. PNX-14 treatment significantly decreased the serum levels of inflammatory cytokines (p < 0.0001). Oxidative contents (MDA and MPO activity) were significantly smaller in the PNX-14 group compared with the IND group (p < 0.0001), while anti-oxidative contents (SOD and catalase activity) were significantly more (p < 0.0001). PNX-14 was superior to FA in several anti-inflammatory properties, such as inhibiting the release of inflammatory cytokines and increasing the catalase activity. PNX-14 showed significant protective effects against the formation of IND-induced duodenal ulcers. These results suggest a promising therapeutic implication for PNX-14 in the treatment of gastrointestinal inflammatory disorders., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© The Author(s), under exclusive licence to Springer Nature B.V. 2022.)

Background: Bone mineral density (BMD) and trabecular bone score (TBS) are moderately correlated. TBS is sometimes used as an adjuvant to BMD in the fracture risk assessment. Some individuals with normal BMD or osteopenia, have more degraded TBS. We aimed to identify factors associated with TBS worse than BMD in the non-osteoporotic elderly population., Methods: The study subjects were selected from 2384 women and men aged ≥60 years participating in the second stage of the Bushehr Elderly Health program, a population-based prospective cohort study in Iran. The BMDs of different sites and the lumbar spine texture were measured using dual-energy X-ray absorptiometry and the TBS algorithm, respectively. Subjects were categorized based on their BMD and TBS status. Logistic regression was performed to identify the factors associated with "TBS worse than BMD" in non-osteoporotic individuals., Results: Of 1335 participants included in the study, 112 of 457 women, and 54 of 878 men had worse TBS than BMD. In multivariable analysis, TBS worse than BMD in women was statistically significantly associated with years since menopause (OR: 1.04 (1.00-1.07)) and waist circumference (OR: 1.09 (1.05-1.14)). However, in men, the condition was statistically significantly associated with waist circumference (OR: 1.10 (1.03-1.17)), current smoking (OR: 2.54 (1.10-5.84)), and HDL-C (OR: 1.03 (1.00-1.06))., Conclusion: The results of the study show that higher waist circumference is associated with more degraded TBS than BMD in both men and women. Years passed since menopause and current smoking, respectively in women and men, were associated with more degraded TBS. Considering TBS values in older individuals with higher waist circumference, or a history of smoking despite normal BMDs might help more accurate assessment of bone health. However, further studies are required to confirm the benefit., (© 2021. The Author(s).)

Introduction: Pregnancy is associated with changes in bone remodeling and calcium metabolism, which may increase the risk of fragility fracture after menopause. We hypothesized that in postmenopausal women, with history of grand multiparity, the magnitude of trabecular bone deterioration is associated with number of deliveries., Methods: 1217 women aged 69.2 ± 6.4 years, from the Bushehr Elderly Health (BEH) program were recruited. The areal bone mineral density (aBMD) of the lumbar spine and femoral neck and trabecular bone score (TBS) of 916 postmenopausal women, with grand multiparity defined as more than 4 deliveries, were compared with those of 301 postmenopausal women with 4 or fewer deliveries. The association of multiparity with aBMDs and TBS were evaluated after adjustment for possible confounders including age, years since menopause, body mass index, and other relevant parameters., Results: The aBMD of femoral neck (0.583 ± 0.110 vs. 0.603 ± 0.113 g/cm 2 ), lumbar spine (0.805 ± 0.144 vs. 0.829 ± 0.140 g/cm 2 ) and TBS (1.234 ± 0.086 vs. 1.260 ± 0.089) were significantly lower in women with history of grand multiparity than others. In the multiple regression analysis, after adjusting for confounders, the negative association did persist for lumbar spine aBMD (beta = -0.02, p value = 0.01), and the TBS (beta = -0.01, p value = 0.03), not for femoral neck aBMD., Conclusion: We infer that grand multiparity have deleterious effects on the aBMD and the trabecular pattern of the lumbar spine., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have influenced the work reported in this paper., (© 2021 The Authors.)

In a large population-based study of Iran, the age-standardized prevalence of osteoporosis was 24.6% in men and 62.7% in women aged ≥ 60 years. Osteoporosis was negatively associated with body mass index in both sexes, and with diabetes in men and hypertriglyceridemia in women., Purpose: Population aging has made osteoporosis and osteoporotic fractures an important health problem, especially in developing countries. This study aimed to explore the prevalence of osteoporosis and associated factors among the elderly population of the south-west of Iran., Methods: Baseline data of the second stage of the Bushehr Elderly Health program was used. Spinal, total hip, or femoral neck osteoporosis was described as a BMD that lies 2.5 standard deviations or more, below the average values of a young healthy adult in the lumbar spine, total hip, or femoral neck, respectively. Osteoporosis at either site was defined as total osteoporosis. Age-standardized prevalence of osteoporosis was estimated. We used the modified Poisson regression with a robust variance estimator to identify the factors related to osteoporosis, adjusting for potential confounders., Results: Overall, 2425 individuals (1166 men) aged over 60 years were included. In all, total osteoporosis was detected in 1006 (41.5%) of the participants. Using the reference value derived from Caucasian women aged 20-29 years, the age-standardized prevalence of total osteoporosis was 24.6 (95% CI: 21.9-27.3) in men, and 62.7 (95% CI: 60.0-65.4) in women. In men, osteoporosis was positively associated with age, smoking, history of fracture, and history of renal/liver diseases and negatively associated with body mass index (BMI) and diabetes. BMI, hypertriglyceridemia, and education were negatively correlated with osteoporosis in women, while years after menopause and history of fracture increased the likelihood of osteoporosis, significantly., Conclusion: Results support the high prevalence of osteoporosis and osteopenia in the elderly population. Considering the importance of severe complications, especially fractures, comprehensive interventions should be expanded.

Objective: The aim of the current study was to determine the possible interaction of the central leptin and Glutamatergic systems on feeding behavior in neonatal 3-hours food deprived (FD 3 ) broilers chickens. Methods: In experiment 1, FD 3 chicken received intracerebroventricular (ICV) injection of control solution (group i) and 2.5, 5 and 10 µg of Leptin (groups ii-iv). In experiment 2, FD 3 chicken were ICV injected with (group i) control solution and groups ii-iv with 2.5, 5 and 10 nmol of AG-490 (JAK 2 antagonist). In experiment 3, injections were (i) control solution, (ii) Leptin (10 µg), (iii) AG-490 (2.5 nmol) and (iv) Leptin + AG-490. In experiment 4, broiler chickens were ICV injected with (i) control solution, (ii) Leptin (10 µg), (iii) MK-801 (NMDA glutamate receptors antagonist; 15 nmol) and (iv) Leptin + MK-801. Experiments 5-9 were similar to experiment 1, except chicken were ICV injected with CNQX (AMPA receptor antagonist, 390 nmol), UBP-302 (Kainate receptor antagonist, 390 nmol), AIDA (mGluR1 antagonist, 2 nmol), LY341495 (mGluR2 antagonist, 150 nmol) and UBP1112 (mGluR3 antagonist, 2 nmol) instead of MK-801. Then, food intake was measured until 120 min after injection. Results: ICV injection of leptin (2.5, 5 and 10 µg) significantly decreased food intake in a dose dependent manner ( p  < 0.05). Also, ICV injection of the JAK 2 antagonist (2.5, 5 and 10 nmol) had hyperphagic effect in chicken ( p  < 0.05). Co-administration of leptin + AG-490, partially decreased leptin-induced hypophagia in broiler chicken ( p  < 0.05). In addition, co-injection of leptin + MK-801 significalty inhibited leptin-induced hypophagia in neonatal chicken ( p  < 0.05). Also, co-administration of leptin + CNQX partially attenuated hypophagic effect of leptin in chicken ( p  < 0.05). Conclusion: The results of present study suggest that leptin has hypophagic effect in neonatal chicken and this effect is probably mediated via NMDA and AMPA glutamatergic receptors.

Because of limitation of doxorubicin (DOX) clinical application in chemotherapy due to its cardiotoxicity, finding new strategies to reduce DOX challenge and improve patients' outcomes is crucial. Due to positive cardiovascular impacts of troxerutin (TXR), here we have investigated the effect of TXR on DOX-induced cardiotoxicity by evaluating the myocardial oxidative stress and expression of genes regulating mitochondrial biogenesis. Male Wistar rats (250-300 g) were randomly allocated into four groups: control, TXR, DOX, and TXR + DOX. Troxerutin (150 mg/kg) was orally administrated once a day through a gavage tube for 4 weeks before DOX challenge. The TXR-treated and time-matched control rats received intraperitoneal injection of DOX (20 mg/kg). Three days after DOX challenge, the left ventricular samples were obtained to determine the expression of genes regulating mitochondrial biogenesis via real-time PCR. Myocardial creatine kinase (CK-mB), oxidative stress markers, and mitochondrial function (generation of reactive oxygen species or ROS and ATP levels) were also evaluated using commercial kits and spectrophotometric and fluorometric methods. DOX administration significantly increased the levels of CK-mB, malondialdehyde (MDA), and mitochondrial ROS levels, while reduced the cellular ATP production and expression levels of SIRT-1, PGC-1α, and NRF-2 as well as superoxide dismutase, glutathione peroxidase, and catalase activity in comparison to control group (P < 0.05 to P < 0.01). Pretreatment of DOX-received rats with TXR significantly upregulated the expression of all biogenesis genes and antioxidant enzymes with non-significant effect on catalase activity, and significantly reduced CK-mB and MDA levels toward control values (P < 0.05 to P < 0.01). Mitochondrial ROS and ATP levels were also restored significantly by pretreatment with TXR (P < 0.05). The data suggested that preconditioning of rats with TXR had protective effect on DOX-induced cardiotoxicity through inducing antioxidative properties and restoring the mitochondrial function and the expression profiles of myocardial SIRT-1/PGC-1α/NRF-2 network.
