Evaluation of the antiparasitic activity of the chitosan-silver nanocomposites in the treatment of experimentally infested pigeons with Pseudolynchia canariensis. Saudi J Biol Sci 2022; 29:1644-1652. [PMID: 35280576 PMCID: PMC8913377 DOI: 10.1016/j.sjbs.2021.10.067] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 10/16/2021] [Accepted: 10/25/2021] [Indexed: 02/06/2023] Open
Abstract
This study aimed to evaluate the efficacy of chitosan-silver nanocomposites in the treatment of experimentally infested pigeons with Pseudolynchia canariensis (P. canariensis) with evaluation of different immunological parameters before and after treatment. Therefore, fourteen birds were divided into 2 groups; group1(infested group including 12 birds) which subdivided into 6 sub-groups experimentally infested pigeons 2 pigeons each, and five group of them were treated with chitosan-silver nanocomposites and sub-group number 6 was treated with deltamethrin while, group 2 including two pigeons were kept as control negative ones. P. canariensis flies distributed under the wing and /or under the tail in infested group and these pigeons showed significantly lower RBCs and higher WBCs than that in non-infested pigeons. The cell mediated immune response against experimentally infested pigeons with P. canariensis was studied. P. canariensis infestation in pigeons have a negative impact on pigeon’s blood parameters, increase TNF-α and IL-1β cytokines levels. This study cleared out the role of P. canariensis in the induction of a case of oxidative stress indicated by high level of nitric oxide and malondialdehyde (MDA) with low antioxidant capacity in shape of reduced zinc concentration in the sera of experimentally infested pigeon. Chitosan-silver nanocomposite has a promising effect in the elimination of P. canariensis infestation in pigeons.

Abstract
The aim of the present study was to clarify the effect of low selenium (Se)/high fat on the mRNA expression of selenoproteins, heat shock proteins (HSPs) and cytokines in pig peripheral blood lymphocytes. Forty crossbred boar piglets with healthy lean body weights of 10 kg were randomly divided into four treatment groups (group C, group L-Se, group H-fat, and group L-Se-H-fat) (n = 10/group) and fed with the corresponding diet for 16 weeks. The pig peripheral blood lymphocytes were extracted, and the mRNA expression of selenoproteins, HSPs, and cytokines was measured. Most mRNA levels for selenoproteins decreased in group L-Se, group H-fat, and group L-Se-H-fat, except Gpx1, Gpx2, Selt, and Selm, which were elevated in group H-fat. At the same time, low-Se/high-fat diet increased the expression of HSPs (HSP40, HSP60, HSP70, and HSP90) and inflammatory cytokines (IL-1α, IL-1β, IL-6, IL-8, IL-9, iNOS, COX-2, NF-κB, and TNF-α) in group L-Se, group H-fat, and group L-Se-H-fat, and genes in group L-Se-H-fat showed greater increases. Also, low-Se/high-fat diet inhibits the expression of TGF-β1 and IFN-γ. In summary, a low-Se/high-fat diet can cause relevant selenoprotein expression changes and promote the expression of pro-inflammatory factors and HSPs, and low Se enhances the expression of HSPs and inflammation factors induced by high fat. This information is helpful for understanding the effects of low-Se and high-fat diet on pig peripheral blood lymphocytes.

Abstract
PURPOSE Host modulatory therapy has been proposed as a treatment for periodontal diseases. A class of herbal medicines, known to be immunomodulators, alters the activity of immune function through the regulation of informational molecules such as cytokines. In the current study, we tested the hypothesis that herbal immunomodulator drugs act as an adjuvant to scaling and root planing (SRP) in alleviating periodontal inflammation by improving clinical and biochemical parameters. METHODS Sixty healthy subjects (30 in each group) with moderate and severe chronic periodontitis were enrolled in a double-blind, placebo-controlled, double-masked randomised controlled trial. The control group was treated with SRP and a placebo, whereas the test group was treated with SRP followed by dietary supplementation of Septilin for 3 weeks. Periodontal clinical parameters and serum C-reactive protein (CRP) levels were evaluated for all patients at the baseline, 3 weeks, and 6 weeks. RESULTS Improved gingival index scores found in the test group as compared to the control group were found to be statistically significant only after 3 weeks (P<0.001). In contrast, the decrease in the sulcus bleeding index and pocket depth scores was statistically highly significant in the test group as compared to the control group after 3 weeks and 6 weeks (P<0.001). However, reduced clinical attachment level and CRP scores, as reflected in the test group as compared to the control group, were not found to be statistically significant after both 3 weeks (P>0.05) and 6 weeks (P>0.05). CONCLUSIONS The results of this clinical-biochemical study suggest that dietary supplementation with herbal immunomodulatory agents may be a promising adjunct to SRP and may aid in improving periodontal treatment outcomes.

Abstract
As rheumatologic diseases became understood to be autoimmune in nature, the drugs used to treat this group of conditions has evolved from herbal or plant derived anti-inflammatory agents, such as salicylates, quinine and colchicine to the many recently approved biological response modifiers. These new drugs, especially the anti-tumor necrosis factor agents, have shown remarkable efficacy in autoimmune diseases, and there are new agents under investigation that will provide additional treatment options. In between, the world was introduced to cortisone and all of its derivatives, as chemical synthesis led to better, more efficacious drugs with lesser side effects. Disease modifying anti-rheumatic agents have actually been around since the first half of the 20th century, but only began to be used in the treatment of autoimmune diseases in the 1970s and 1980s. One advantage is that they have been invaluable in their ability to offer "steroid sparing" to decrease the adverse effects of steroids. Research over the past decade has resulted in a new class of drugs that influence cytokine regulatory pathways such as the Janus associated kinase inhibitors. The promise of personalized medicine now permeates current research into new pharmacological agents for the treatment of autoimmune disease. The new appreciation for the gene-environment interaction in the pathogenesis of most diseases especially those as heterogeneous as autoimmune diseases, has led to our focus on targeted therapies. Add to that the new knowledge of epigenetics and how changes in DNA and histone structure affect expression of genes that can play a role in immune signaling, and we now have a new exciting frontier for cutting edge drug development. The history of treatment of autoimmune diseases is really only a little over a century, but so much has changed, leading to increasing lifespans and improved quality of life of those who suffer from these ailments.

Abstract
Prostaglandin E(1) (PGE1) shows various pharmacological activities including anti-inflammation. However, the rapid metabolization and inactivation of the intravenously administered PGE1 during the first passage through the lungs result in significant non-compliance in clinical trials which greatly limits its application. The aim of this work was to prepare the lipid nanoparticles loading PGE1 to improve its anti-inflammatory effect with low side-effect. The experimental results showed that PGE1 loaded lipid nanoparticles (PLNs) could be successfully prepared by high pressure homogenization with particle size 68.1+/-4.7 nm, zeta potential -3.32+/-0.37 mV and entrapment efficiency 92.1+/-1.3%. PLNs exhibited a sustained release with low burst drug release. PLNs could improve the inhibition effects of PGE1 on lipopolysaccharides (LPS)-induced TNF-alpha expression on macrophage RAW264.7 cells, and improve the inhibition of lymphocyte to endothelial cell adhesion and ICAM-1 adhesion molecule expression on HUVEC and MDA-MB-468 cell membrane. No allergenicity, vascular and muscle irritation were induced in animals by PLNs even at double of the highest drug concentration of clinical infusion. As a result, PLNs could be a more potential delivery system for PGE1 in the treatment of inflammation-related diseases.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease of unknown etiology and is mainly characterized by the progressive erosion of cartilage leading to chronic polyarthritis and joint distortion. Although the exact pathogenesis of the disease has yet not been elucidated, however, studies suggest that cellular proliferation of synoviocytes result in pannus formation which damages the cartilage and bone. Recent reports also support the role of free radicals in its pathogenesis. Apart from the conventional treatment strategies using nonsteroidal anti-inflammatory drugs, disease modifying antirheumatic drugs and glucocorticoids, newer and safer drugs are continuously being searched, as long term usage of these drugs have resulted in adverse effects. Alternative medicine provides another approach for treatment of RA and currently a number of medicinal plants are under scientific evaluation to develop a novel drug. There is a dire need to investigate the complete therapeutic potential and adverse effects, if any, of these herbals for providing newer and safer treatment options with minimum side effects. In this review we have tried to explore various Indian ancient Ayurvedic, Unani and Tibbi, as also some Chinese and Korean, herbals for their potential to treat RA.

Abstract
The focus of this study was to clarify the relation between the nitric oxide (NO) production and cytokine expression including tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), and also investigated the effect of COS on LPS stimuli from RAW 264.7 cell. The lipopolysaccharide (LPS) of Gram-negative bacteria induces the expression of cytokines and potent inducers of inflammatory cytokines such as TNF-alpha and IL-6. In this experiment, upon stimulation with increasing concentrations of chitosan, the LPS-stimulated TNF-alpha and IL-6 secretion was significantly recovered within the incubation media of RAW 264.7 cells. Consistently, RT-PCR with mRNA and Western blot with anti-cytokine antiserum including TNF-alpha and IL-6 showed that the amount of TNF-alpha and IL-6 secretion in the incubation media recovered with the concentration of chitosan. The LPS-stimulated NO secretion was significantly recovered within the 6h and 12h incubation media of RAW 264.7 cells, too. The recovery effect of chitosan on IL-6 and NO secretion may be induced via the stimulus of TNF-alpha in RAW 264.7 cell. These results once again suggest that chitosan oligosaccharide may have the anti-inflammatory effect via the stimulus of TNF-alpha in the LPS-stimulated inflammation in RAW 264.7 cells.

Abstract
With the availability of the human genome sequence and those of related species like chimpanzee, mouse, and rat, data driven research for tackling the molecular grounds of rheumatoid arthritis (RA), a multifactorial polygenic disease, can be considered a realistic challenge to the scientific community. A comprehensive research strategy is presented enabling the integration of multiple research efforts on studying autoimmunity by so called systems biology approaches. An integrative scientific concept is discussed of how to unravel molecular mechanisms of complex diseases by making use of state-of-the-art methodologies in functional and comparative genomics. A continuous interchange of data-driven and hypothesis-driven research is adjoined to determine the nature of rheumatic diseases with autoimmune background. Instead of studying single genes and proteins, RNA and protein microarray profiles are currently obtained in numerous research projects producing read-outs termed gene signatures rather than DNA and/or protein markers. A comprehensive study of the RNA, protein, and metabolite regimes is undertaken that eventually will lead to a "holistic" view of how all respective molecules, pathways and cells themselves interact with each other. Some of the above mentioned research aspects have already been studied by the authors, hopefully leading to new diagnostics and therapeutics in the future.
