The need for effective bacterial resistance treatment is urgent and unmet due to the rise in morbidity and mortality that has coincided with the prevalence of infections caused by MDR bacteria. Using its creative and unconventional methods, effective antibiotics for MDR bacteria could be developed using nanomedicine techniques. To combat microbial resistance, a number of strategies have been developed, including the use of natural bactericides, the introduction of fresh antibiotics, the application of combination therapy and the creation of NP-based antibiotic nanocarriers. The absence of novel antibacterial agents has worsened the situation for MDR bacteria. Ineffective antibiotics used to treat MDR bacteria also contribute to the bacteria's tolerance growing. Nanoparticles (NPs) are the most efficient method for eliminating MDR bacteria because they serve as both carriers of natural antibiotics and antimicrobials and active agents against bacteria. Additionally, surface engineering of nanocarriers has important benefits for focusing on and modifying a variety of resistance mechanisms. The use of nanocarrier systems in drug delivery for overcoming bacterial resistance is covered in this review along with various mechanisms of antibiotic resistance.</p>","PeriodicalId":19800,"journal":{"name":"Pakistan Journal of Biological Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10227650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DNA analysis consists of DNA isolation, PCR analysis and sequencing analysis. The record data were used for association study with the mathematical model: Y&lt;sub&gt;ij&lt;/sub&gt; = μ+G&lt;sub&gt;i&lt;/sub&gt;+Є&lt;sub&gt;ij&lt;/sub&gt;. &lt;b&gt;Results:&lt;/b&gt; Research showed that one common SNP of g.217_218.indel.TTTTA (5'UTR) and three novel SNPs of c.386G>C (exon 1), g.641_642.indel.T (intron 2) and c.4957G>C (exon 3) were detected in the present study. In this study, a novel SNP on exon 1 and intron 2 of Saburai &lt;i&gt;MSTN&lt;/i&gt; gene has a moderate PIC value (>0.30). In addition, a novel SNP on exon 1 and exon 3 of the Saburai &lt;i&gt;MSTN&lt;/i&gt; gene was detected as a missense mutation of A55P and A43P, respectively. Goats with the heterozygous genotype have higher growth traits compared to goats with the homozygous genotype. &lt;b&gt;Conclusion:&lt;/b&gt; The goats with heterozygous genotypes can be further developed to increase the productivity of Saburai goats.</p>","PeriodicalId":19800,"journal":{"name":"Pakistan Journal of Biological Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71413460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to its availability, largely without labeling, in many food products, unintentional overuse of this food additive may occur. The objective of this study was to find out how selenium nanoparticles affected the toxicity of MSG in male albino rats' testicles. &lt;b&gt;Materials and Methods:&lt;/b&gt; As 35 Wistar male rats partitioned into 5 groups: G1: Control rats, G2: Received Se-NPs at 0.4 mg kg&lt;sup&gt;1&lt;/sup&gt; b.wt., orally, G3: Injected with MSG at a daily dose of 4 g kg&lt;sup&gt;1&lt;/sup&gt; b.wt., intraperitoneally (IP), G4: Ingested a daily oral dose of Se-NPs for 7 successive days and on the 7th day, received the first dose of MSG IP 4 g kg&lt;sup&gt;1&lt;/sup&gt; b.wt., then received both treatments till the end of the study and G5: Administered a daily oral dose of 4 g kg&lt;sup&gt;1&lt;/sup&gt; MSG, followed by Se-NPs at a daily dose of 0.4 mg kg&lt;sup&gt;1&lt;/sup&gt; b.wt., the experiment continued for 28 days. Serum testosterone hormone, Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), the levels of serum lipid peroxidation (MDA), reduced Glutathione (GSH), Glutathione Peroxidase (GSH-Px), superoxide dismutase (SOD) and Lactate Dehydrogenase (LDH) were estimated and samples from testis were separated for histological analysis. &lt;b&gt;Results:&lt;/b&gt; The MSG treatment induced a significant decline in the values of serum testosterone, FSH, LH, GSH, GSH-Px and SOD. It also increased the values of serum MDA and LDH and spermatic arrest. While, the administration of Se-NPs orally before MSG treatment resulted in a decline in the values of serum MDA and LDH, an elevation in the values of serum GSH, GSH-PX and SOD, testosterone, FSH, LH and reappearance of sperm. &lt;b&gt;Conclusion:&lt;/b&gt; The use of Se-NPs as a protector exhibited more improvement in values of estimated hormones and oxidative stress markers than using it as a therapy.</p>","PeriodicalId":19800,"journal":{"name":"Pakistan Journal of Biological Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71413461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
