Background: Chitosan nanoparticle (chitosan-NPs) is a polymer obtained from the exoskeletons of crustaceans, and has been applied recently as a carrier for many drug agents. Multi-drug resistance has been the major set-back in the treatment of microbial infections globally. Methods: Dibutyl phthalate (DBP) isolated from Melastomastrum capitatum leaves was encapsulated in chitosan-NPs and its antimicrobial activity was evaluated on selected multi-drug resistant pathogens. The isolated phthalate was characterized by FTIR, NMR and GC-MS. Chitosan-NPs encapsulated phthalate was prepared by ionic gelation of glutaraldehyde cross-linker. Antimicrobial activity of nano encapsulated drugs was carried by agar well diffusion at 0.5 µg/mL concentration. In vivo activity of nano encapsulated drugs were determined in thirty Swiss albino rats weighing 100-150g. Chitosan-NPs encapsulated treatment groups were administered at 0.5 µg/mL (i.p.) as compared with ciprofloxacin positive control group at 2.5 µg/mL. Results: Chitosan-NPs encapsulated phthalate showed the strongest zones of inhibition against VRE ATCC 29212, MRSA NCTC 13435, Candida albicans ATCC 19231, and Clostridiodes difficile NCTC14385. Significant inhibition of bacterial growths was achieved by CSDBP encapsulated phthalate both in vitro and in vivo studies due to low concentrations in ALT, ALP, AST and creatinine, and high volume of WBC in rats. Non-Fickian drug release was observed by the formulations. Conclusion: The study showed that chitosan-NPs mediated drug delivery exhibited strong antimicrobial activity with sustained release against multi-drug microbes in this study. This is promising, and can be employed as mediation for multi-drug resistant pathogens.
背景:壳聚糖纳米颗粒(Chitosan - nps)是从甲壳类动物的外骨骼中提取的一种聚合物,近年来作为药物的载体得到了广泛的应用。多药耐药一直是全球微生物感染治疗的主要障碍。方法:采用壳聚糖- nps包埋法对从头状草叶片中分离得到的邻苯二甲酸二丁酯(DBP)进行抑菌活性测定。通过FTIR、NMR、GC-MS对分离得到的邻苯二甲酸酯进行了表征。采用戊二醛交联剂离子凝胶法制备壳聚糖- nps包封邻苯二甲酸酯。以0.5µg/mL浓度琼脂孔扩散法对纳米包封药物进行抑菌活性检测。以30只体重100-150g的瑞士白化大鼠为实验对象,测定纳米胶囊化药物的体内活性。壳聚糖- nps包封治疗组以0.5µg/mL (i.p)给药,环丙沙星阳性对照组以2.5µg/mL给药。结果:壳聚糖- nps包封邻苯二甲酸酯对VRE ATCC 29212、MRSA NCTC 13435、白色念珠菌ATCC 19231和艰难梭菌NCTC14385的抑制作用最强。在体外和体内研究中,由于大鼠体内ALT、ALP、AST和肌酐浓度低,白细胞体积大,包封邻苯二甲酸酯的CSDBP对细菌生长都有显著的抑制作用。观察了制剂的非菲克式药物释放。结论:壳聚糖nps介导的药物传递对多种药物微生物具有较强的缓释活性。这是有希望的,并且可以用作多重耐药病原体的中介。

Background: Heat stress (HS) has negative effects on economic parameters of the poultry industry. Different strategies such as nutritional additives are used to alleviate negative effects of HS. The use of multiattribute decision-making (MADM) could help to select the best additive for alleviating the effects of the HS.  Thus, the present study was conducted to investigate the effects of probiotic, prebiotic and synbiotic on growth performance and immune responses of broiler chicks affected by HS via MADM method. Methods:Two-hundred and forty broiler chicks were randomly assigned into 4 treatments with 6 replications and 10 broiler chicks per replication. The birds were treated with probiotic, prebiotic, and synbiotic for 42 days. A group was considered as control and received only basal diet. Stress condition was induced from 21 to 42 days of age. Growth performance and humoral immunity were assessed, then calculated and analyzed by MADM method. Results:The results showed that dietary supplementation of probiotic, synbiotic, prebiotic and control had coefficients of 0.762, 0.702, 0.581 and 0.00, respectively.  Dietary supplementation of probiotic, prebiotic and synbiotic had better effects compared with control group. Conclusions:Therefore, dietary supplementation of probiotic may have better efficiency compared with other additives based on the MADM. The use of probiotics can be suggested for improving growth and immunity under the HS condition in the poultry industry.
背景:热应激(HS)对家禽业的经济参数有负面影响。不同的策略,如营养添加剂,以减轻HS的负面影响。多属性决策(MADM)的应用有助于选择最优的添加剂来减轻HS的影响。因此,本试验通过MADM法研究了益生菌、益生元和合成菌对HS影响下肉鸡生长性能和免疫反应的影响。方法:240只肉仔鸡随机分为4个处理,每处理6个重复,每个重复10只鸡。分别给予益生菌、益生元和合成菌42天。A组为对照组,仅饲喂基础日粮。21 ~ 42日龄诱导应激条件。测定生长性能和体液免疫,并用MADM法计算和分析。结果:饲粮中添加益生菌、合成菌、益生元和对照的系数分别为0.762、0.702、0.581和0.00。与对照组相比,饲粮中添加益生菌、益生元和合成菌效果更好。结论:基于MADM,饲粮中添加益生菌的效果可能优于其他添加剂。建议在HS条件下使用益生菌促进家禽业的生长和免疫。

Background: The essential oils of the plant synergize the synthetic chemical pesticide activity against pests. Controlling pests mainly with synthetic chemical pesticides causes the resistance to build up in these pests like S. littoralis. Methods: This study was conducted to evaluate the synergistic effect of garlic and thymol oils with cypermethrin and chlorpyrifos on field populations of S. littoralis. Also, the impact of the mixtures on activities of three enzymes: Glutathione S-transferase (GST), general esterase (ά-β-EST) and mixed function oxidase (MFO) of S. littoralis using dipping technique. Results: Bioassay shows elevated LC50 for each of cypermethrin and chlorpyrifos alone. Whereas, the toxicity of cypermethrin and chlorpyrifos were synergized 2.81- to 9-fold; 2.74- to 8.35-fold by garlic oil respectively, but far less synergism occurred with thymol oil. The analysis showed the GST, ά-β-EST and MFO were notably inhibited by garlic and thymol oils synergism with cypermethrin and chlorpyrifos in S. littoralis. Conclusions: The results concluded that inhibition of the enzymes could be the result of the synergist of the essential oils when it mixed with synthetic insecticides to control S. littoralis in the field.
背景:植物精油与合成化学农药具有协同作用。主要用合成化学农药防治害虫,会使滨水蓟等害虫产生抗药性。方法:研究大蒜百里香精油与高效氯氰菊酯、毒死蜱对滨海夜蛾田间种群的增效作用。采用浸渍法,研究了不同浓度的混合物对滨草谷胱甘肽s -转移酶(GST)、一般酯酶(α -β-EST)和混合功能氧化酶(MFO)活性的影响。结果:氯氰菊酯和毒死蜱单独使用后LC50均升高。氯氰菊酯与毒死蜱的毒性协同效应为2.81 ~ 9倍;大蒜油的增效作用是大蒜油的2.74 ~ 8.35倍,但与百里酚油的增效作用要小得多。结果表明,大蒜和百里香精油与氯氰菊酯和毒死蜱的协同作用显著抑制了滨海海棠的GST、α -β-EST和MFO。结论:精油与合成杀虫剂混用,对上述酶的抑制作用可能是其协同增效作用的结果。

Background: Despite significant efforts, the artemisinin-based drugs are still very expensive due to the limited production of this metabolite within wild Artemisia spp . plants. Therefore, the current work set out to evaluate the effect of chitosan nanoparticles, as a novel elicitor to characterize the expression of genes functioning in artemisinin synthesis pathway using a comparative experimental investigation. Methods: The suspensioncultures of A. anuua were exposed to 5, 10, 15 mg/L of chitosan nanoparticles (during 8, 24, 48 and 72 h upon treatment). The expression of DBR2, SQS, CYp , ADS, CPR and ALDH genes were quantified by qRT-PCR technique. Results: Chitosan nanoparticles were effective in inducing artemisinin production at 15 mg/L after 8 h, and 5 and 10 mg/L after 72 h of elicitation, in which all the ADS, CYp , CPR, DBR2 and ALDH genes were upregulated except SQS. Conclusion: The treatment of 5 mg/L after 72 h, when cells entered the stationary and then death phases, is recommended because it seems chitosan nanoparticles require more time to up-regulate the ADS, CYP and ALDH genes and thereby probably enhance the artemisinin content. The results suggest that chitosan nanoparticles can be used as a novel effective elicitor for artemisinin production.
背景:尽管付出了巨大的努力,但由于野生青蒿属植物中这种代谢物的产量有限,以青蒿素为基础的药物仍然非常昂贵。植物。因此,本研究旨在通过对比实验研究,评估壳聚糖纳米颗粒作为一种新型激发子对青蒿素合成途径中功能基因表达的影响。方法:分别用5、10、15 mg/L的壳聚糖纳米颗粒培养羊草(处理后8、24、48、72 h)。采用qRT-PCR技术检测DBR2、SQS、CYp、ADS、CPR和ALDH基因的表达。结果:壳聚糖纳米颗粒诱导8 h后15 mg/L、72 h后5 mg/L和10 mg/L产生青蒿素,除SQS外,ADS、CYp、CPR、DBR2和ALDH基因均表达上调。结论:建议在细胞进入静止期和死亡期后72h用5mg /L处理,因为壳聚糖纳米颗粒需要更多的时间上调ADS、CYP和ALDH基因,从而可能提高青蒿素含量。结果表明,壳聚糖纳米颗粒可作为一种新型的高效促生剂用于青蒿素的生产。

Background: Multiple sclerosis (MS) is an autoimmune disease in which a deficiency of vitamin B12 along with folic acid can contribute to its progression. The aim of this study was to investigate the role of these two vitamins in altering myelin base protein (MBP) in the MS model of rats and also to measure some ionic parameters in serum. Methods: Brain histology was followed by analysis of the relationship between vitamin B12 treatment or folic acid and MBP as well as changes in total protein concentration (TPC). MBP expression was assessed by SDS-PAGE and serum levels of iron. Copper and zinc were also assessed by Duncan test. Results: MBP expression in cortical extract was increased by simultaneous treatment with vitamin B12 and folic acid compared with the groups treated individually. Histological examinations showed that the highest level of tissue repair was in the same group. There was a significant difference between cortical TPC in the control and treatment of vitamin B12 and folic acid, but serum levels of Fe, Zn and Cu were not significantly different between the groups. Conclusion: It can be concluded that the combination of these vitamins increases the expression of MBP protein.

Background: The protective activity exerted by Psidium guajava on the nervous system has been suggested to be via its antioxidant composition; however, its role in mercury-induced neurotoxicity remains elusive. This study investigated the ameliorative activity of ethanolic extract of P. guajava leaves on mercuric chloride-induced toxicity in the cerebral cortex of male Wistar rats. Methods: Thirty-five (35) male Wistar rats were separated into seven groups with five rats each. Group, I served as control, Group II received 41.5 mg/kg of mercuric chloride (HgCl2), Group III received 1000 mg/kg bwt of EEPGL, Group IV received 41.5 mg/kg of HgCl2 and distilled water, Group V received 41.5 mg/kg of HgCl2 and 500 mg/kg bwt of EEPGL, Group VI received 41.5 mg/kg of HgCl2 and 1000 mg/kg bwt of EEPGL, while Group VII received 41.5 mg/kg HgCl2 and 1190 mg/kg bwt of Vitamin C. At the end of the administration, the brains of the Wistar rats were excised, oxidative stress markers quantified and brain tissues were fixed in Bouin’s fluid, processed, and stained for histological studies. Results: The results revealed a significant decrease in body weight gain and oxidative stress markers, weak staining of Nissl substance and cytoarchitectural distortion of the cerebral cortices of Wistar rats in mercuric chloride only treated groups when contrasted to the Control and the Groups co-administered mercuric chloride and increasing doses of EEPGL. Conclusion: Ethanolic extract of P. guajava leaves was able to ameliorate neurotoxicity induced by mercuric chloride exposure by mitigating against oxidative stress, preventing weight loss and distortion in the cytoarchitecture of the cerebral cortex.

Introduction: Diabetes is a biological problem of life in a new way in human societies, especially in developing countries. Environmental and genetic factors are mutually influential in the incidence and exacerbation of this disease. One of the genes is the transcription factor TCF7L2 that has been proven in many studies in different communities to play a role in diabetes and is located on chromosome 10. Two SNPs for this gene, rs12255372 and rs7903146, have been recorded on the NCBI site and have a direct and significant correlation with type 2 diabetes. In this study, the genotypic frequency of these two SNPs was studied using ARMS and HRM techniques. Materials: This study was performed on 100 patients with type 2 diabetes and 100 healthy individuals as non-diabetic controls. Diabetics were selected from patients referred to Ali Asghar Diabetes Clinic in Zahedan. The control group consisted of individuals who did not meet the criteria for diabetes or had no family history of diabetes in first- or second-degree relatives. DNA extraction was performed using the phenol-chloroform method and finally, PCR was performed for a specific primer. Results: ARMS results showed that the number of people with SNP rs7903146 ​​in diabetic patients is significantly higher than those in the control. However, the difference was not significant for rs12255372. HRM results were also highly correlated with ARMS and showed very precise allelic differentiation in the studied population for both positions. Conclusion: In general, since HRM is a relatively inexpensive technique and a large number of samples can be analyzed in a few hours, the results of this study can be used in the preparation of diagnostic kits based on this method in these two and other sites related to diabetes.
导读:糖尿病是人类社会,特别是发展中国家的一种新的生命生物学问题。环境和遗传因素在该病的发生和恶化中相互影响。其中一个基因是转录因子TCF7L2,该基因位于第10号染色体上,在不同社区的许多研究中已被证明在糖尿病中发挥作用。该基因的两个snp rs12255372和rs7903146已在NCBI位点被记录,与2型糖尿病有直接且显著的相关性。本研究采用ARMS和HRM技术对这两个snp的基因型频率进行了研究。材料:本研究以100例2型糖尿病患者和100例非糖尿病健康人为对照。糖尿病患者是从转诊到扎黑丹Ali Asghar糖尿病诊所的患者中选出的。对照组由不符合糖尿病标准或一、二度亲属中无糖尿病家族史的个体组成。用苯酚-氯仿法提取DNA,最后对特定引物进行PCR。结果:ARMS结果显示,糖尿病患者中携带SNP rs7903146的人数明显高于对照组。而rs12255372的差异不显著。人力资源管理结果也与ARMS高度相关,并且在两个职位的研究人群中显示出非常精确的等位基因分化。结论:总的来说,由于HRM是一种相对便宜的技术,并且可以在几个小时内分析大量的样本,因此本研究的结果可以用于在这两个以及其他与糖尿病相关的部位制备基于该方法的诊断试剂盒。
