QUERCETIN CAUSES TO DECREASE PROXIMAL TUBULES APOPTOTIC CELLS IN STREPTOZOTOCIN-INDUCED DIABETIC RAT

Enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus. Wistar male rat (n=40) were allocated into three groups, control group (n=1O) and quercetin (QR) group that received 15mg/kg (IP) QR, (n= 10), and Diabetic group that received 55mgjkg (IP) streptozotocin (STZ) (n=20) which was subdivided to two groups of 10STZ group and treatment group. Treatment group received 55mgjkg (IP) STZ plus 15mg/jkg QR, daily for 4 weeks, respectivelyhowever, the control group just received an equal volume of distilled water daily(IP) . Diabetes were induced by a single (IP) injection of streptozotocin (55mg/kg). Animals were kept in standard condition. In 28 day after inducing diabetic 5 mL blood were collected for Total Af1tioxidant Capacity (TAC), Malondi Dehyde (MDA) and Oxidized Low density Lipoprotein (Ox-LDL) levels and kidney tissues of Rat in whole groups were removed then prepared for Apoptosis analysis by Tunel metho. Apoptotic cells significantly decreased in group that has received 15mg/kg (IP) quercetin (

Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BackgroundDisorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021.MethodsWe estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined.FindingsGlobally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer.InterpretationAs the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed

A Survey of Ofloxacin Histopathological Effect on Fetus Rat Heart

Objective: Ofloxacin is an antibiotic of the fluoroquinolone group consisting of broad-spectrum antibiotics widely used in various infectious diseases. Nearly 600 teratogenic factors are known that cause congenital disease in laboratory animals. One of these factors is drugs. The aim of this study was to determine the effect of ofloxacin on the development of fetus rat heart. Materials and Methods: In this study, 4-month-old Wistar rats with 300 gram weight were used and were housed in an environmentally controlled room. A group of 3 females were caged with a single male of proven fertility overnight. Finding of vaginal plug on the following morning was regarded as a gestational day 0. Pregnant rats were divided into 2 groups (control and experimental). The first were fed with rodent food and the second with rodent food plus 50 mg/kg ofloxacin every day. After collection of tissue specimen from rat newborns the heart was dissected and prepared for light microscopy. Results: The results showed that in the group receiving ofloxacin, in comparison with the control group, myocardial cells were smaller and contain highly dense nuclei. Conclusion: In conclusion, the results show that the above mentioned drug could be transferred through placenta and affect the normal development of myocardial cells. These changes could have negative effects on the function of the heart after birth

Effects of Artemisia lanata Extract on Reproductive Parameters of Female Rats

Objective: Until date, there is no report on safety of Artemisia lanata. This study aimed to determine the possible undesirable effects of A. lanata on reproduction of female rats. Materials and Methods: The pregnant rats were treated (i.p.) with vehicle or 200 and 400mg/kg of A. lanata hydroalcoholic extract from the 2-8 day of pregnancy. Then, number and weight of neonates, duration of pregnancy, and percent of dead fetuses were determined. Furthermore, cytotoxicity of this plant was tested using fibroblast (L929) and Chinese hamster ovary (Cho) cell lines. Results: The A. lanata had no significant effect on duration of pregnancy, average number of neonates, and weight of neonates. However, administration of 200 and 400 mg/kg of the extract led to 30 and 44% abortion in animals, respectively. The extract at concentrations ≥ 200 μg/ml significantly (P < 0.001) inhibited the proliferation of L929 fibroblast cells. Regarding the Cho cells, the extract induced toxicity only at concentration of 800 μg/ml (P < 0.010). Conclusion: Our results showed that continuous consumption of A. lanata in pregnancy may increase the risk of abortion and also may have toxic effect on some cells

Identification of Staphylococcus aureus in Synovial Fluid of Patients Suspected to Arthritis Through PCR in Urmia City

Objective: Synovial fluid is composed of plasma ultrafiltration and hyaluronic acid secretion by synovial cells. Synovial fluid plays a role as softener and feeding cartilages without vessels. Infectious arthritis is one of the commonest arthritis and if the disease did not cure in the first days it would injure cartilages irreversibly. The goal of this study was identification of Staphylococcus aureus in synovial fluid of patients suspected to arthritis through PCR in Urmia city. Materials and Methods: In this research synovial fluid contamination with Staphylococcus aureus and biochemical parameters such as the amount of glucose, protein and the number of white blood cells were studied. Amplification of nuc gene with the length of 279 bp using PCR method was applied to confirm Staphylococcus aureus isolation. Results: For this, 400 cerebrospinal fluid samples were tested from hospitalized patients with arthritis in two hospitals in Urmia city during 3 months, which out of them 109 of samples were contaminated with bacteria including: 78 of isolates were Staphylococcus aureus, 12 of them were coagulase negative Staphylococci, 4 of them were Streptococcus and 15 of them were gram negative bacilli. Also, results showed that the amounts of glucose in positive samples in comparison to the amount of glucose in synovial fluid were significantly decreased. The amount of protein and the number of white blood cells in synovial fluid of positive samples were significantly higher in comparison to normal synovial fluid. Conclusion: Results showed that Staphylococcus aureus is the most common agent at infections arthritis, therefore it is recommended to use an experimental treatment for Staphylococcus aureus prior to final results

The Correlation of Adiponectin, and Visfatin Serum Levels With Ischemic Heart Disease in Postmenopausal women: A population-Based Study

Background: There is a controversial evidence about adiponectin role in cardiovascular diseases and visfatin role has been suggested in pathogenesis of coronary artery disease. Material and Methods: A total of 378 postmenopausal women were randomly selected from 13 clusters in Bushehr Port. The prevalence of ischemic heart disease was assessed by using the Minnesota Code with a 12-lead resting electrocardiogram (EKG). Serum adiponectin and visfatin levels were measured by using enzyme-linked immunosorbent assay methods Results: A total of 159 patients (41.8 percent) were suffering from ischemic heart disease. There was no significant difference between women with ischemic heart disease and healthy postmenopausal women in adiponectin serum level. However, diabetic women with ischemic heart disease, compared with healthy postmenopausal women had a higher level of visfatin (Geometric Mean: 3.05&plusmn;1.84 ng/ml versus 2.52&plusmn;1.90 ng/ml, respectively; p=0.023). Multiple logistic regression analysis indicated that higher serum levels of visfatin were significantly associated with a higher prevalence of ischemic heart disease after adjusting for potential confounders, including classical cardiovascular risk factors and circulating hs-CRP levels [odds ratio=3.26, confidence interval (1.14-9.68), p=0.027]. Conclusion: Adiponectin was not correlated with ischemic heart disease among postmenopausal women. But visfatin serum level correlated with ischemic heart disease in postmenopausal non-diabetic women independently from cardiovascular risk factors

Electrocoagulation Process for Treatment of Detergent and Phosphate

Background & Aims of the Study: Detergent and phosphate are one of the main and vital threats (eutrophication phenomenon and production of synthetic foam) for the source of drinking water, agriculture and industrial uses in the Ahvaz, Iran that threaten human health. The aim of this study is the evaluation of the efficiency of the electrocoagulation (EC) process in the removal of detergent and phosphate from car wash effluent. Materials & Methods: In this experimental study, we used a glass tank with a volume of 2-4 liters (effective volume of 2 liters) containing 4 electrode-plate iron and aluminum (AL-AL, AL-Fe, Fe-Fe). Bipolar method was used to convert alternative electricity to direct; electrodes were connected to a power supply. Daily samples were collected from different car washes sewage. Initial PHs of samples was from 7 to 9. At first, different tests were performed on primary samples. Reaction times were set for 90, 60 and 30 minutes with middle intervals of 2 cm. Results: According to the result of this study, percentage of phosphate removal in the EC with Al-Fe electrode, with an optimum pH = 7, has been from 34 % (in the 10 Volt) to 78% (in the 30 Volt). Percentage of detergent removal in the EC with AL electrode, with an optimum pH = 7, has been from 68 % (in the 10 Volt) to 94% (in the 30 Volt). Conclusions: Altogether, it was found that this method can be used as a confident and convenient method for treating car wash effluent and according to the highest removal efficiency of the process, effluent can be discharged safely into the environment

Ellagic acid ameliorates neuroinflammation and demyelination in experimental autoimmune encephalomyelitis: Involvement of NLRP3 and pyroptosis

Multiple sclerosis (MS) is presented as the most common autoimmune and demyelinating neurological disorder with incapacitating complications and with no definite therapy. Most treatments for MS mainly focus on attenuation of its severity and recurrence. To model MS reliably to study pathogenesis and efficacy of possible chemicals, experimental autoimmune encephalomyelitis (EAE) condition is induced in rodents. Ellagic acid is a neuroprotective polyphenol that can protect against demyelination. This study was planned and conducted to assess its possible beneficial effect in MOG-induced EAE model of MS with emphasis on uncovering its modes of action. Ellagic acid was given p.o. (at doses of 10 or 50 mg/kg/day) after development of clinical signs of MS to C57BL/6 mice immunized with MOG35�55. Results showed that ellagic acid can ameliorate severity of the disease and partially restore tissue level of TNFα, IL-6, IL-17A and IL-10. Besides, ellagic acid lowered tissue levels of NLRP3 and caspase 1 in addition to its mitigation of neuroinflammation, demyelination and axonal damage in spinal cord specimens of EAE group. As well, ellagic acid treatment prevented reduction of MBP and decreased GFAP and Iba1 immunoreactivity. Taken together, ellagic acid can decrease severity of EAE via amelioration of astrogliosis, astrocyte activation, demyelination, neuroinflammation and axonal damage that is partly related to its effects on NLRP3 inflammasome and pyroptotic pathway. © 2020 Elsevier B.V

ZnO Q-dots as a potent therapeutic nanomedicine for <i>in vitro</i> cytotoxicity evaluation of mouth KB44, breast MCF7, colon HT29 and HeLa cancer cell lines, mouse ear swelling tests <i>in vivo</i> and its side effects using the animal model

<p>Nanoformulations derived from fine porous ZnO quantum dot nanoparticles (QD NPs) can offer strong potential medical applications; especially in cancer therapy. ZnO QD NPs was synthesized by sol–gel hydrothermal process, fast cold quenching and further smart surface functionalization methods to obtain ultrasmall size (1–4 nm) NPs. ZnO nanopolymer, a wetting agent, PEG co-solvent and water<b>/</b>oil emulsion stabilizer were considered in our nanofluid formulation. The resulting nanofluid was characterized by SEM, FTIR, photoluminescence, band gap energy, zeta potential and UV–Vis spectroscopy. The cytotoxic effects on the growth of four cancer cell lines were evaluated by MTT assay. The IC₅₀ (µg/ml) values of 30, 41, 40 and 35 for KB44, MCF-7, HT29 and HeLa cells, respectively, after 48 h of nanoformulation treatment suggested the cytotoxic effect of this nanoformulation on these cell lines in a concentration-dependent manner (<i>p</i> < .05). ZnO nanofluid destroyed cancer cell lines more efficiently than the normal HFF-2 (IC₅₀= 105 µg/ml). The reduction in cell viability in response to ZnO nanofluid treatment induced apoptosis in the cultured cells. Skin sensitization test plus antibacterial activity were also measured. Side effect tests on 70 white mice <i>in vivo</i> resulted in only 3–4 abnormal situations in hepatic tissue section possibly due to the idiosyncratic drug reactions.</p
