The emerging role of α7nAChRs/caspase-3/Nrf-2 signaling pathway in citicoline improved autistic behavior induced by thimerosal in mice. Int Immunopharmacol 2024; 130:111736. [PMID: 38401462 DOI: 10.1016/j.intimp.2024.111736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Revised: 02/13/2024] [Accepted: 02/19/2024] [Indexed: 02/26/2024]
Abstract
AIMS Autism spectrum disorder (ASD) is a global concern,affecting around 75 million individuals.Various factors contribute to ASD,including mercury-containing preservatives like thimerosal (Thim) found in some vaccines.This study explored whether citicoline could be a therapeutic option for Thim-induced neuronal damage in a mouse model of ASD.Additionally,the study investigated the effects of citicoline on the α7nAChRs/Akt/Nrf2/caspase-3 pathway,which may be involved in the development of ASD. MATERIALS AND METHODS The study separated newborn mice into four groups.The control group received saline injections,while the Thim group received intramuscular injections of 3000 μg Hg/kg Thim on days 7,9,11,and 15 after birth.The two citicoline groups were administered Thim followed by intraperitoneal injections of 250 mg/kg or 500 mg/kg citicoline for three weeks.Afterward,various parameters were assessed, including growth,behavior,brain histopathology,oxidative stress,apoptotic,and inflammatory markers. KEY FINDINGS Untreated Thim-exposed mice exhibited significant brain damage,which was substantially alleviated by citicoline treatment.This beneficial effect was associated with increased expressions and concentrations of brain α7nAChRs and Akt, increased brain content of Nrf2, and the hippocampus contents of acetylcholine. Citicoline treatment decreased the brain levels of oxidative stress markers (MDA and NO),the apoptotic marker caspase-3,and pro-inflammatory markers (NF-κB,TNF-α,and IL-1β). The drug also increased the brain GPx activity. SIGNIFICANCE Based on the results of this study,the α7nAChRs pathway appears to be essential for the therapeutic effectiveness of citicoline in treating Thim-induced ASD in mice.

Abstract
Glioblastoma multiforme (GBM) is the most common, aggressive, and fatal primary malignant brain tumor in adults. The therapeutic efficacy of temozolomide (TMZ) is limited owing to frequent treatment resistance. The latter is in part related to the overexpression of redox systems such as the thioredoxin system. This system is fundamental for cell survival and proliferation, regulating hypoxia inducible factor-1alpha (HIF-1α) activity, in turn controlling vascular endothelial growth factor (VEGF), which is indispensable for tumor invasiveness, angiogenesis and microenvironment maintenance. HIF-1α can also be regulated by the signal transducer and activator of transcription 3 (STAT3), an oncogene stimulated by pro-inflammatory cytokines and growth factors. The thioredoxin system has several known inhibitors including mercury compounds such as Thimerosal (TmHg) which readily crosses the blood-brain barrier (BBB) and accumulates in the brain. Though previously used in various applications epidemiological evidence on TmHg's neurotoxicity is lacking. The objective of this study was to verify whether thimerosal is a suitable candidate for hard repurposing to control glioblastoma; therefore, the effects of this molecule were evaluated in human GBM (U87) cells. Our novel results show that TmHg decreased cellular viability (>50%) and migration (up to 90% decrease in wound closure), reduced thioredoxin reductase (TrxR/TXNRD1) and thioredoxin (Trx) activity, and increased reactive oxygen species (ROS) generation. Moreover, TmHg reduced HIF-1α expression (35%) as observed by immunofluorescence. Co-exposure of U87 cells to TmHg and TMZ reduced HIF-1α, VEGF, and phosphorylated STAT3. Consequently, TmHg alone or combined with chemotherapeutic drugs can reduce neoangiogenesis and ameliorate glioblastoma progression and treatment.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS coronavirus 2, or SARS-CoV-2) is the cause of the respiratory infection known as COVID-19. From an immunopathological standpoint, coronaviruses such as SARS-CoV-2 induce increased levels of a variety of T-helper 1 (Th1) and inflammatory cytokines and chemokines, including interleukin-1 (IL-1), IL-6, CCL2 protein, and CXCL10 protein. In the absence of proven antiviral agents or an effective vaccine, substances with immunomodulatory activity may be able to inhibit inflammatory and Th1 cytokines and/or yield an anti-inflammatory and/or Th2 immune response to counteract COVID-19 symptoms and severity. This report briefly describes the following four unconventional but commercially accessible immunomodulatory agents that can be employed in clinical trials to evaluate their effectiveness at alleviating disease symptoms and severity: low-dose oral interferon alpha, microdose DNA, low-dose thimerosal, and phytocannabinoids.

Abstract
INTRODUCTION Helicobacter pylori infection is due to the high prevalence in population attracts the clinical interest of researchers in the whole World. It is well known that this microorganism not only resides in the mucosa of the gastrointestinal tract, but is also defined in the periodontal pocket of the oral cavity. THE AIM OF INVESTIGATION: to evaluate Helicobacter pylori diagnostics in the mouth and prove a method of relief of the inflammatory process by applying immunomodulator Imudon. RESULTS. On the basis of obtained results it was found that the inclusion of topical immunomodulator Imudon in the complex therapy of Helicobacter pylori-associated diseases leads to reduction of inflammatory potential through the decrease of the TNFα, IL-6 activity in saliva and to increase the protective properties of saliva as a result of increased levels of mucin, significantly reduces the frequency of relapses in the one year after therapy. CONCLUSION It is practically important to determine the effectiveness of eradication therapy by the study of the contents of the tooth-gingival pocket for the detection of genetic material of Helicobacter pylori, as well as to include in the complex therapy of Helicobacter pylori-associated diseases of the immune modulator Imudon.

Abstract
An 18-year-old female presented with a severe ulcerative lesion on her right ear of 6 weeks duration. Her right ear was edematous and erythematous with a large, painless ulcerative lesion covering a third of the pinna and satellite papular lesions on the posterior. She was diagnosed with chiclero's ulcer. A skin smear stained with Diff-quik showed abundant Leishmania parasites. Chiclero's ulcer is a rare clinical presentation and is typically severe and difficult to treat. Physicians in Ecuador recommend administering prolonged intramuscular Glucantime. Side effects are common and can be severe resulting in low patient compliance. Because of preferences of the patient and the large volume needed for her weight, we recommended topical treatment with a lotion of Glucantime mixed half and half with white Merthiolate. After applying this lotion to the lesion 3 to 4 times a day for 6 weeks, the lesion healed.

Abstract
The objective of the present study was to develop a rationale for the application of imudon (a bacterial lysate preparation)in the treatment of the patients presenting with chronic tonsillitis based on the elucidation of characteristics of local immunity in the oropharynx (determined from the results of cytograms, immunoenzyme assays for the quantitation of IgG, sIgA, IgA, and IgM antibodies, and calculation of the relative secretion coefficients). A total of 74 patients with chronic tonsillar pathology (24 children and 50 adults) were available for the observation along with 42 subjects having no tonsillar pathology with concomitant chronic bacterial rhinosinusitis. The control group was constituted by 25 practically healthy subjects. It was shown that the local application of imudon in the patients with the preserved function of palatine tonsils (in the absence of symptoms of chronic inflammation) produces the adequate response of the humoral and cellular immunity systems. In the patients with the simple form of chronic tonsillitis imudon therapy ensured statistically significant activation of congenital immunity including the phagocyte function and a tendency toward normalization of antibody formation. It is concluded that alteration of the function of palatine tonsils in the patients presenting with the toxico-allergic form (ТАФ-2) of chronic tonsillitis implies the necessity of surgical treatment (tonsillectomy).

Abstract
The Centers for Disease Control and Prevention Advisory Committee on Immunization Practices recommends routine influenza vaccination for all women who are or will be pregnant during the influenza season. During seasonal influenza epidemics, during previous pandemics, and with the current influenza A (H1N1) pandemic, pregnancy places otherwise healthy women at increased risk for serious complications from influenza, including death. Inactivated influenza vaccine can be safely and effectively administered during any trimester of pregnancy. No study to date has demonstrated an increased risk of either maternal complications or adverse fetal outcomes associated with inactivated influenza vaccination. Moreover, no scientific evidence exists that thimerosal-containing vaccines are a cause of adverse events among children born to women who received influenza vaccine during pregnancy. In this article, we review the evidentiary basis for the recommendation of vaccination of all women who will be pregnant during the influenza season and safety data of influenza vaccination during pregnancy.

Abstract
PURPOSE To report a case of unilateral total limbal stem cell (LSC) failure and corneal opacification secondary to thimerosal- and contact lens-induced ocular surface toxicity. METHODS Interventional case report and review of the literature on thimerosal-induced ocular surface changes. RESULTS A 49-year-old woman with a 2-year history of long-term soft contact lens wear developed unilateral total LSC failure and corneal opacification secondary to presumed thimerosal-induced toxicity and contact lens wear. At presentation, best-corrected visual acuities were 20/120 in the right eye and 20/15 in the left eye. The patient underwent a keratolimbal allograft and amniotic membrane graft followed by a penetrating keratoplasty. At the last follow-up, the right eye showed a clear corneal graft with a best-corrected visual acuity of 20/30. CONCLUSIONS Thimerosal toxicity can lead to total LSC failure with secondary corneal vascularization and opacification. Keratolimbal allograft followed by penetrating keratoplasty can be successful in reconstructing the ocular surface in such cases.

Abstract
Thimerosal is an organomercury compound with sulfhydryl-reactive properties. The ability of thimerosal to act as a sulfhydryl group is related to the presence of mercury. Due to its antibacterial effect, thimerosal is widely used as preservatives and has been reported to cause chemically mediated side effects. In the present study, we showed that the molecular mechanism of thimerosal induced apoptosis in U937 cells. Thimerosal was shown to be responsible for the inhibition of U937 cells growth by inducing apoptosis. Treatment with 2.5-5 microM thimerosal but not thiosalicylic acid (structural analog of thimerosal devoid of mercury) for 12 h produced apoptosis, G(2)/M phase arrest, and DNA fragmentation in a dose-dependent manner. Treatment with caspase inhibitor significantly reduced thimerosal-induced caspase 3 activation. In addition, thimerosal-induced apoptosis was attenuated by antioxidant Mn (III) meso-tetrakis (4-benzoic acid) porphyrin (Mn-TBAP). These data indicate that the cytotoxic effect of thimerosal on U937 cells is attributable to the induced apoptosis and that thimerosal-induced apoptosis is mediated by reactive oxygen species generation and caspase-3 activation.

Abstract
BACKGROUND AND AIM OF THE STUDY The study aim was to compare the crosslink stability and calcification behavior of porcine tissue (cusp and wall), treated with a new antimineralization process (ADAPT) with that of commercially prepared Freestyle and Prima Plus bioprosthetic tissues. METHODS Porcine aortic roots were divided into two groups: (i) tissue zero pressure-fixed with 0.625% glutaraldehyde (GA) for seven days and stored in 0.25% GA (as control); and (ii) tissue exposed to the ADAPT process for four days and stored in 0.25% buffered GA. These groups were compared with Freestyle and Prima Plus tissues (cusp and wall). Crosslink stability was assessed by shrinkage temperature and resistance to pronase degradation. Calcification behavior was assessed histologically (Von Kossa staining) and by atomic absorption spectrophotometry of explanted tissue after eight weeks. in a subcutaneous rat model. RESULTS Crosslink stability and calcification potential of ADAPT-treated porcine valve cusps were comparable to those of Freestyle and Prima Plus cusps (p = NS). ADAPT-treated porcine wall tissue showed improved crosslink stability (p <0.05) and significantly (p <0.001) reduced calcification (-95.95%) compared to control (-0.00%), Freestyle (-47.87%) and Prima Plus (-51.95%) tissues. CONCLUSION The ADAPT process is effective in reducing calcification in both porcine cusp and wall tissues in a subcutaneous rat model, and further suggest that enhanced crosslinking plays an important role in minimizing aortic wall calcification.

Abstract
Autism, a neurodevelopmental disorder, may involve autoimmune pathogenesis. Since mercury is potentially a risk factor for autoimmunity, we conducted a study of mercury-induced antinuclear and antilaminin antibodies in autistic and normal children who had been pre-administered with thimerosal-containing vaccines. Laboratory analysis by different immunoassays showed that the serum level of these two autoimmune markers did not significantly differ between autistic and normal children. This finding suggests that the mercury as in thimerosal-containing vaccines is likely not related to autoimmune phenomenon in autism.

Abstract
OBJECTIVE Hepatitis B vaccine is recommended for all infants, and the series may be started during the delivery admission. For infants who are born either to women who are positive for hepatitis B surface antigen (HBsAg) or to women whose HBsAg status is unknown, vaccination should be started within 12 hours of birth to prevent perinatal and early childhood hepatitis B virus infection. Because of concerns about mercury exposures from vaccines that contain thimerosal, the United States Public Health Service (USPHS) and the American Academy of Pediatrics (AAP) recommended in July 1999 that the first dose of hepatitis B vaccine be deferred until 2-6 months of age but only for infants who are born to HBsAg-negative women. To assess the impact on birth-dose vaccine coverage for infants who are born to women with unknown HBsAg status, we measured coverage before and after July 1999. METHODS A sample of Michigan infants who were born to women whose HBsAg status was either unknown or missing were identified by reviewing newborn screening cards for infants who were born during 1) March-April 1999 (before recommendation changes [T1]); 2) July 15-September 15, 1999 (immediately after recommendation changes [T2]); and 3) March-April 2000 (6 months after resumption of pre-1999 practices were recommended [T3]). We verified maternal HBsAg screening and newborn hepatitis B vaccination by reviewing infant and maternal hospital records. RESULTS Of 1201 infants who were born to women whose HBsAg status was indicated as unknown or missing on the newborn screening card during the 3 time periods, 216 (18%) were born to women whose status was truly unknown at the time of delivery, as determined by medical record review. During T1, 53% of these 216 infants received hepatitis B vaccine before hospital discharge, compared with 7% of infants who were born during T2 and 57% of infants who were born during T3. During T1, 19% of these infants received hepatitis B vaccine within 12 hours of birth compared with 1% of infants who were born during T2 and 14% of infants who were born during T3. CONCLUSIONS Hepatitis B vaccine birth-dose coverage for infants who were born to women whose HBsAg status was unknown at the time of delivery was already low in Michigan before the July 1999 USPHS/AAP Joint Statement but decreased significantly during the 2 months after the USPHS/AAP Joint Statement. Abrupt changes in established vaccination recommendations for lower risk children may lead to decreased coverage among higher risk children. Increases in hepatitis B vaccine coverage at birth are necessary to reduce the risk of perinatal infection for infants who are born to women with unknown HBsAg status.

Abstract
OBJECTIVE To compare the efficacy, tolerability and local tolerance of diclofenac sodium 0.1% containing hydroxypropylgamma cyclodextrin preserved with benzalkonium chloride 0.005% (Voltaren Ophtha CD), with that of diclofenac sodium 0.1% preserved with thiomersal 0.004% (Voltaren Ophtha) in the treatment of inflammation after cataract-intraocular lens surgery. DESIGN AND SETTING Randomised 2:1, double-masked, parallel-group study in six centres in Germany. STUDY PARTICIPANTS 299 patients scheduled to undergo phacoemulsification with posterior chamber intraocular lens implantation. INTERVENTIONS Study medications were instilled four times in the 30 minutes before surgery and four times daily from the first postoperative day. MAIN OUTCOME MEASURES The key efficacy variable was the reduction in anterior chamber flare (photons/millisecond) from day 1 to day 6 to 8. Patients underwent comprehensive ocular examinations, including laser flaremetry (KOWA), preoperatively and postoperatively at days 1, 6 to 8 and 24 to 32. RESULTS 268 patients (Voltaren Ophtha CD 177, Voltaren Ophtha 91) completed the day 6 to 8 visit without any protocol violations. Reduction in the degree of intraocular inflammation with Voltaren Ophtha CD was equivalent to that achieved with Voltaren Ophtha at the day 6 to 8 [95% confidence interval (CI) -3.07 to +0.54] and day 24 to 32 (95% CI -1.44 to +1.40) visits. Although there was no significant (p = 0.464) difference between the two study groups in patients' global assessment of local tolerance at day 24 to 32, ocular discomfort was significantly (p = 0.023) less with Voltaren Ophtha CD compared with Voltaren Ophtha. CONCLUSIONS Voltaren Ophtha CD was as effective and well tolerated but had less ocular discomfort compared with Voltaren Ophtha in the treatment of ocular inflammation after phacoemulsification with intraocular lens implantation. This new formulation of diclofenac sodium 0.1% may be used as an alternative to the existing formulations of ophthalmic diclofenac sodium 0.1%.

Abstract
Thimerosal (TH) (ethylmercurithiosalicylate) is a mercurial compound with the ability to exert cytoprotective effect against several ulcerogens. This investigation was undertaken to study the mechanism by which TH exerts its gastro-protective effect in rats. Acid secretion studies were undertaken in pylorus-ligated shay rats with and without TH treatment. The level of nonprotein sulfhydryls (NP-SH), myeloperoxidase (MPO) and gastric wall mucus were also measured in the glandular stomach of rats following ethanol-induced gastric lesions. The results of this study showed that TH (0.3, 1.0 and 3.0 mg/kg) significantly and dose-dependently reduced gastric secretion and acidity in pylorus-ligated shay rats and protected animals against ethanol-induced gastric injury. Pretreatment of animals with TH significantly attenuated ethanol-induced depletion of NP-SH and increase in MPO in glandular mucosa. Thus, gastro-protective effect of TH may be attributed to its ability to reduce acid secretion, oxidative stress, and neutrophil activity besides it well reported effect on gastro-protective PG and NO.

PURPOSE To evaluate the effectiveness of the topical application of Timerosal (merthilate tintura) in mycosis involving the external auditory canal. PATIENTS AND METHODS The study includes 152 patients with the clinical, otoscopic and microscopic diagnosis of otomycosis. Results were assessed 72 hours and 10 days after the application. RESULTS Bacteriological study was performed in 83 patients, finding Aspergilly niger in 54.0% of the cases, Candida albicans in 25.4%, Aspergillus fumigatus in 15.8% and Penicillium in 4.8%. Improvement at 72 h. was found in 66.4% and at 10 days in 93.4% of the patients. Bacteriological contamination was found in 6.6% of the total. COMMENTS In most of the patients, the otomycosis healed after cleaning of the external auditory canal and topical application of timerosal. This method is easy to apply, fast, effective, of low cost and few side effects.

Abstract
Avian pox is an important disease in birds of prey in Bahrain. A live pigeon pox vaccine was administered to hunting falcons (Falco species) together with other therapeutic methods to arrest the development of primary stage pox lesions and for the treatment of well established secondary stage pox lesions. Quarantine and general hygiene procedures were also used as an integral part of the management and control of the disease.

Abstract
During a 3 weeks period, an immunotherapy by oral route was applied in patients presenting periodontal diseases (gingivitis and chronic adult periodontitis). This study, double blindly conducted, points out a statistically significative decrease of the main clinical symptoms of periodontal diseases (bleeding, erythema, oedema, pain, suppuration, fetidness) without any other local treatment and shows the interest of such a therapy in addition to the classical local treatments applied to patients presenting periodontal diseases.

Abstract
Outside of the antibiotics, numerous general medications are prescribed in the context of the treatment of periodontal diseases. It appeared to be of interest to study them. The international research on anti-inflammatory drugs will be analysed in the literature. An in-depth study will then be carried out on documents provided by laboratories which market products likely to be active on periodontal diseases in France. All the publications concerning Imudon, Piascledine 300 and Insadol will be more particularly analysed. The operative protocols, conditions and experimentation, as well as the results, will be studied as objectively as possible so as to determine the essential efficacy of one or nother product.

Abstract
Different quantities of the preservative thimerosal in inactivated Newcastle disease oil-emulsion vaccines were tested to determine the influence on the hemagglutination-inhibition (HI) response of broilers. The effect of thimerosal was measured in vaccines that had been stored for 1, 21, and 52 weeks; HI serology was conducted at 2, 4, and 6 weeks after vaccination. Mean HI titers 4 weeks after vaccination decreased at a significant rate (P less than or equal to 0.001) with increasing concentrations of thimerosal. HI titers 4 weeks after vaccination with 1-week-old vaccine were significantly (P less than or equal to 0.05) higher than those after vaccination with 52-week-old vaccine at all thimerosal concentrations tested. Titers were also significantly higher (P less than or equal to 0.05) after vaccination with 1-week-old vaccine than after vaccination with 21-week-old vaccine at all thimerosal concentrations below about 8.25 mg/ml of antigen. Thimerosal at the levels recommended in commercial vaccines does not significantly decrease vaccine efficacy.

Abstract
Abdominal adhesions were experimentally induced in rats by gentle scraping. Severe adhesions developed in 38.7% of the control animals. The flavonoid cianidanol ( [+]-cyanidanol-3), an in vitro inhibitor of procollagen production, was administered intragastrically or intraperitoneally in doses of 9 to 72 mg per rat. Administered intraperitoneally at a dose of 36 or 72 mg per rat, cianidanol substantially inhibited adhesion formulation, when given immediately, three days, or five days after surgery. Oral administration of the drug was less effective in preventing the formation of adhesions. Thimerosal, another connective-tissue inhibitor, was found to be toxic at doses of 2.5 or 5 mg per rat, and its effect on the prevention of adhesion formation was poor. The ability of cianidanol to inhibit the development of abdominal adhesions in rats suggests that a possible approach to treatment is to inhibit the production of procollagen and thus prevent the formation of the collagenous fibers that are the cause of adhesions.

Abstract
Samples of fresh and fixed tissues from infants with exomphalos treated by thiomersal application were analysed for mercury content. The results showed that thiomersal can induce blood and organ levels of organic mercury which are well in excess of the minimum toxic level in adults and fetuses. The analysis of fresh and fixed tissues must be carefully controlled against normal tissues in order to interpret mercury levels accurately.

Abstract
This article reports a new concept in the treatment of tear film abnormalities. Solubilization of an artifical tear insert provides a continuous flow of polymer into the tear film in place of intermittent drop therapy. The physiochemical properties of succinylated collagen were studied in vitro and compared favorably with presently available tear substitutes. The use of this polymer as a solid solubilizable insert was evaluated in normal patients. It was found to be comfortable, resulted in no blurring of vision, and prolonged the tear film breakup time.

Abstract
From 1972 to 1974, 736 children had tympanostomy tubes inserted for chronic serous otitis media resistant to medical therapy. The total number of ears involved was 2,237. The cleft palate patients constituted 8.8% of the total and had 15.4% of all procedures. Patients with allergy comprised 19% of the total population and had a higher incidence of otitis media following tube insertion. Adenoidectomy was performed in 44% of all patients and 35% of these required further tube insertions, suggesting that adenoidectomy in combination with tube insertion is not necessarily the primary treatment of choice. Children under six made up 78.5% of the total. The most common complication, a draining ear with an incidence of 15.1% was treated successfully with aqueous Merthiolate irrigations. There were 14 tympanic membrane perforations.
