Finke, Maureen D published the artcileAscending tonic-clonic seizure syndrome in a dog following inadvertent intrathecal use of ionic contrast agent., SDS of cas: 117-96-4, the main research area is .

OBJECTIVE: To describe the successful management of ascending tonic-clonic seizure syndrome in a dog after inadvertent intrathecal administration of ionic contrast material. CASE SUMMARY: A 7-year-old, 5.9 kg, male castrated Miniature Pinscher inadvertently received intrathecal ionic contrast material during a myelogram to investigate cervical pain. Ascending tonic-clonic muscle spasms quickly progressed to generalized seizure activity that was resistant to anticonvulsant medications. The dog developed complete respiratory arrest, which necessitated mechanical ventilatory support for 26 hours. Pneumonia developed and was treated successfully. After resolution of seizure activity and resumption of voluntary respiration, the dog remained tetraparetic for 16 days and was not able to walk on his own for 20 days post contrast injection. Despite a prolonged recovery, the patient survived and recovered normal neurologic function. NEW OR UNIQUE INFORMATION PROVIDED: Intrathecal administration of ionic contrast material resulting in ascending tonic-clonic seizure syndrome is rarely reported in the human and veterinary literature. No previous veterinary report has described successful treatment after prolonged respiratory arrest. In previous veterinary reports, patients recovered complete neurologic function within hours to days in contrast to this report in which the patient was tetraparetic for 16 days. This report demonstrates complete recovery from intrathecal ionic contrast administration is possible despite a high dose of contrast and a prolonged recovery.

Peptanariu, D published the artcileOptimization of culture conditions for bone marrow stromal cells in RPMI-1640 medium., HPLC of Formula: 117-96-4, the main research area is .

Bone marrow mesenchymal stem cells are important for both research and clinical purpose. A number of culture methods for these cells are available on the market, many of them consisting of specialized growing media in combination with growth factors. Our goal was to optimize a less expensive culture method for bone marrow mesenchymal cells. MATERIAL AND METHODS: Eight samples of bone marrow aspirates from patients were used. Out these 8 samples 2 were from healthy people, 3 from chronic granulocytic leukemia patients, 2 from multiple myeloma patients and 2 from patients with myelodysplastic syndrome. Bone aspirates from healthy people were used to optimize the culture method and the rest were used for testing the optimized method. Two methods were tried: 1. Cell culture starting from whole bone marrow, 2) cell culture after bone marrow separation in density gradient with Histopaque. RESULTS: Cell culture starting from whole bone marrow gives better yields for mesenchymal stem cells than methods which include gradient density separation of mononuclear cells with Ficoll-Histopaque. CONCLUSIONS: We have optimised a less expensive cell culture method for bone marrow mesenchymal cells.

Inal, Salih published the artcileProtective effect of adrenomedullin on contrast induced nephropathy in rats., Application In Synthesis of 117-96-4, the main research area is .

BACKGROUND AND AIMS: Contrast-induced nephropathy (CIN) has a growing incidence in which renal vasoconstriction and medullary hypoxia are important mechanisms. Therapeutic approaches are very restricted and there is a considerable interest in advancing preventive strategies. Adrenomedullin is a relatively novel peptide having antioxidant, vasoactive and vasodilatory properties. We aimed to investigate whether adrenomedullin might have a preventive role against the development of experimental CIN. METHODS: Wistar albino rats (n=24) were allocated randomly into four equal groups of 6 each; Control (C), Adrenomedullin (A), Contrast Media (CM) and Adrenomedullin plus Contrast Media (ACM). All rats were deprived of water from day 1 to day 4 during 72 hours. Then, intravenous administrations of chemicals were performed. Adrenomedullin was given at dose of 12µg/kg to groups A and ACM. A single dose of high-osmolar contrast media; diatrizoate (Urografin 76%, Schering AG, Germany) was injected to groups CM and ACM at dose of 10mL/kg. On day 1 and 6 blood samples were drawn for renal function tests and inflammatory markers including TNF-α IL-1β, IL-6 and IL-18. After sacrification, kidney histologies were examined with hematoxylin-eosin staining. RESULTS: Compared to CM group, serum cystatin-C levels on 6th day were found significantly lower in ACM group (p<0.05). Additionally, daily protein excretion rates, absolute changes in daily urine output and creatinine clearance values were significantly lower in ACM group than those in CM group (p<0.05). In histopathological evaluation, regarding the degree of tubular damage and medullary congestion scores, ACM group had slightly better scores compared to CM group; however the differences did not reach significance as shown in inflammatory markers. CONCLUSION: This study demonstrated a beneficial impact of adrenomedullin on deteriorated renal function tests in an experimental CIN model. Adrenomedullin might be a candidate agent for prophylaxis of CIN. However, further studies are needed to shed more light on this issue.

Baykara, Murat published the artcileIn vivo nephroprotective efficacy of propolis against contrast-induced nephropathy., Synthetic Route of 117-96-4, the main research area is .

PURPOSE: Contrast agents administered in diagnostic imaging or interventional procedures of clinical radiology may cause contrast-induced nephropathy (CIN). Preventive measures against CIN involve pharmaceutical pretreatments, such as N-acetylcystein (NAC) or calpain, but alternative medicines can also be helpful. This study aims to assess the prospects of a natural compound, propolis, as a potential nephroprotector against a specific contrast agent, diatrizoate. METHODS: In vivo experiments were performed on 35 male rats in five groups: control, diatrizoate alone, and pretreatments with propolis, NAC, or calpain one hour before diatrizoate administration. Three days later, blood and renal tissue samples were collected and quantitatively processed for determining induced changes in critical biomarkers malondialdehyde (MDA), glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT), as well as serum creatinine and plasma urea. RESULTS: Diatrizoate increased creatinine (113%), urea (400%), and MDA (162%) levels and decreased GSH (-71%), SOD (-69%), GSH-Px (-77%), and CAT (-73%) levels. Evaluating the response of each pretreatment provided sufficient evidence that propolis was as effective as either NAC or calpain, but consistently more prominent in restoring the MDA, GSH, SOD, and GSH-Px levels close to their normal range. This outcome demonstrated the nephroprotective effect of propolis against CIN. CONCLUSION: Propolis protects renal tissue against toxicity, free radicals, and other adverse effects induced by diatrizoate. This function is most likely exerted through the antioxidant and antitoxic activities of propolis.

Yurtçu, Müslim published the artcileThe healing effects of tissue glues and healing agent locally applied on esophageal anastomoses., Computed Properties of 117-96-4, the main research area is .

OBJECTIVE: This study aimed to investigate the effects of cyanoacrylate (C), fibrin glue (FG), and natrium hyaluronate (NH) on the healing of esophageal anastomosis (EA). METHODS: Twenty-four rabbits were divided equally into 4 groups: primary anastomosis (PA), C, FG, and NH. A 1-cm-length of the cervical esophagus was resected through a cervical incision and then anastomosis was performed. C, FG, and NH were instilled into anastomosis lines in the respective groups. The animals were fed orally on postoperative day 7 on the condition that there was no esophageal leakage. The rabbits were sacrificed 8 weeks later to evaluate bursting pressure (BP), tissue hydroxyproline (HP) levels and wound healing scores (WHSs) in the anastomosis lines. RESULTS: BP was significantly higher in the C group than in the PA, FG, and NH groups, and HP was significantly lower than in the other groups. WHSs in the PA and NH groups were lower than in the C and FG groups. CONCLUSIONS: C and NH appear to be beneficial in EA healing with respect to increased BP and decreased HP when they are used simultaneously with PA prophylactically to prevent esophageal leakages and stricture.

Mallios, A published the artcileCurative treatment of pelvic arteriovenous malformation–an alternative strategy: transvenous intra-operative embolisation., Synthetic Route of 117-96-4, the main research area is .

OBJECTIVES: Pelvic arteriovenous malformations (AVMs) are difficult to treat. Arterial embolisation is the most common strategy but often has poor results. We report an alternative surgical approach of controlled intra-operative transvenous embolisation with long-term results in seven cases. MATERIALS AND METHODS: Between 1980 and 2008, we treated seven patients (four men, three women, mean age 50 years). Indications were rectal bleeding (one case), urinary tract problems (four cases), oedema of lower limb (one case) and high-output cardiac failure (one case). Four of them had previous operations and three had previous attempts for embolisation. Embolisation of the malformation was performed through the internal iliac vein. This was done after clamping of all the feeding and draining vessels. The agent used was cyanocrylate (one case), Ethibloc (one case) and bone wax (five cases). RESULTS: Mortality was 0%. Complications occurred in two patients (28,5%), one pulmonary embolism and one regressive femoral paresis. Three patients were re-operated for various reasons. The mean follow-up period was 6 years (1-12 years). Symptoms resolved in all patients, while control by computed tomography (CT) angioscan revealed one residual shunt. CONCLUSION: Complete surgical excision of pelvic AVMs is not always possible. Embolisation does not offer a permanent cure. Intra-operative transvenous embolisation of persisting complex AVMs appears to be an alternative approach with good immediate and long-term results. Ethylene glycol appears to be the most suitable agent.

Wang, Anping published the artcileOpen Tubular Capillary Electrochromatography-Mass Spectrometry for Analysis of Underivatized Amino Acid Enantiomers with a Porous Layer-Gold Nanoparticle-Modified Chiral Column, SDS of cas: 151-10-0, the main research area is .

By developing a novel chiral column, we integrate open tubular capillary electrochromatog. into sheathless mass spectrometry (MS) for efficient anal. of underivatized amino acid enantiomers. The chiral column is easily fabricated by modifying the inner surface of a capillary with a three-dimensional porous layer (PL, thickness ~ 90 nm, pore size ~ 30 nm) and gold nanoparticles and by introducing a chiral selector, thiol β-cyclodextrin (SH-β-CD), onto the modified surface via Au-S bonds. This approach greatly enhances the sp. surface area and thus the ratio of the stationary phase to mobile phase and interaction between the stationary phase and analytes. The proposed PLOT@Au@CD column is coupled to the sheathless CE-ESI-MS system for chiral anal. of amino acid enantiomers. No derivatization of amino acids is required for chiral anal., and baseline separation of a total of 15 pairs of amino acid enantiomers is achieved within 17 min with high column efficiencies of 5.60 x 104 to 1.82 x 106 N/m, high resolutions of 1.51-10.0, and low limits of detection between 0.02 and 0.09 μg/mL. The separation efficiency and MS intensity are only slightly decreased over 60 runs or after usage for 15 days, showing excellent repeatability and stability of the PLOT@Au@CD column. The proposed method is successfully applied to the determination of amino acid enantiomers in vinegar samples with satisfactory accuracy. Our study provides a new approach for developing a chiral stationary phase in the chromatog. separation technique, which can be easily coupled to sensitive MS detection, thus it would be of value for various applications in the fields of chiral anal.

Pan, Hun-Shan published the artcileTotal laparoscopic hysterectomy (TLH) versus coagulation of uterine arteries (CUA) at their origin plus total laparoscopic hysterectomy (TLH) for the management of myoma and adenomyosis., Quality Control of 1205-17-0, the main research area is .

We tried to evaluate the relative feasibility, surgical duration and complications of total laparoscopic hysterectomy (TLH) versus coagulation of uterine arteries at their origin (CUA) plus total laparoscopic hysterectomy for the management of myoma and adenomyosis, and to compare the estimated blood loss for both procedures. A total of 123 patients underwent TLH or CUA plus TLH for the treatment of symptomatic myoma and adenomyosis. Sixty-four women underwent TLH, whilst 68 women underwent coagulation of uterine arteries at their origin plus TLH. The mean weight and volume of the uterus as determined following TLH was 288.1+/-102.4 gm (range 182.1 approximately 396.2 gm.) and 451+/-340.6 cm(3) (range 107.4 approximately 792), respectively. The mean weight of the uterus following CUA plus TLH was 269.1+/-151.7 gm (range 215.8 approximately 430.1) whilst the mean uterine volume was 472.7+/-377.8 cm(3) (range 93.7 approximately 851.2). No significant differences with respect to surgical duration (95 vs. 96.5 minutes TLH vs. CUA + TLH; p>0.05), blood loss (177.2+/-80.1 ml for TLH and 154.9+/-30.21 ml for CUA+TLH; p>0.05) and mean+/-SD preoperative (12.05+/-1.70 gm/dl for TLH and 12.14+/-1.38 gm/dl for CUA+TLH; p>0.05) and post-operative hemoglobin level (11+/-1.03 for TLH and 11+/-1.49 for CUA + TLH; p>0.05) were observed between the two study groups. The blood loss for TLH is comparable to that for the CUA plus TLH procedure.

Boardman, Simone J published the artcileMultimodality treatment of pediatric lymphatic malformations of the head and neck using surgery and sclerotherapy., Application of Diatrizoic Acid, the main research area is .

OBJECTIVES: To describe a multimodality approach to the management of pediatric head and neck lymphatic malformations using surgery, sclerotherapy, or both and to review the outcomes of these approaches. DESIGN: Retrospective case series. SETTING: A single pediatric tertiary care referral center. PATIENTS: Ninety-seven pediatric patients (aged 1 month to 16 years) diagnosed as having lymphatic malformations of the head and neck during a 7-year period. Follow-up ranged from 3 months to 7 years. INTERVENTIONS: All of the patients underwent clinical and radiologic (magnetic resonance imaging) assessment. Treatment modality was selected according to disease location, cyst size, and parental preference. Treatments included surgery (open excision, tongue reduction, electrocautery, and laser treatment), sclerotherapy with OK-432 (Picibanil) or a fibrosing agent (Ethibloc), and a combination of modalities. MAIN OUTCOME MEASURES: Clinically determined responses to treatment, complications, and number of treatments required. RESULTS: All isolated neck disease had complete or near-complete responses, with no nerve palsies sustained. Although most patients achieved complete or near-complete responses, disease with parotid, laryngopharyngeal, or oral components had poorer outcomes and frequently required multiple treatments. Significant long-term neural injury was sustained in 3 of 6 surgical patients for mediastinal disease and in only 4% (n = 4) of other surgical procedures. CONCLUSIONS: Surgery retains an important role in the treatment of pediatric head and neck lymphatic malformations despite the advent of sclerotherapy. Isolated neck disease has an excellent outcome with either modality. Treatment decisions were made via a problem-based approach and were individualized according to anatomical location and disease classification.

Bassal, Ravit published the artcileRisk Factors for Multiple Infections with Salmonella, Shigella, and Campylobacter in Single Individuals Identified in Israel between 1999 and 2020: A Case-Case Control Study., Quality Control of 86-51-1, the main research area is .

BACKGROUND: Salmonella, Shigella, and Campylobacter are highly prevalent among children. Reports on risk factors of patients infected with all three pathogens, not simultaneously, are scarce. OBJECTIVES: To identify risk factors for multiple infection with Salmonella, Shigella, and Campylobacter in the same child. METHODS: Using the Israel Sentinel Laboratory-Based Surveillance Network, we conducted a retrospective observational case-case-control study among children aged 0-9 years. A case was defined as a child infected with Salmonella, Shigella, and Campylobacter at different occasions between January 1999 and December 2020. A control was defined as a child infected with a single pathogen once, during the same period. Logistic regression models were applied to determine the association between multiple infections and demographic characteristics. RESULTS: We identified 109 cases (0.1%) infected with Salmonella, Shigella, and Campylobacter, and 86,511 controls (99.9%) infected with only one bacteria type. In a multivariable analysis, we showed that being Jewish (odds ratio [OR] 2.4, 95% confidence interval [95%CI] 1.3-4.4), having residency in Jerusalem (OR 3.2, 95%CI 1.3-7.7), or in the southern district (OR 3.7, 95%CI 1.5-8.8) were independent risk factors for multiple infection. CONCLUSIONS: Although very rare, non-simultaneous infection with multiple bacteria does occur in Israel. National and local authorities should promote programs to encourage proper hygiene practices, which are culture-adjusted.
