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.

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.

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.

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.

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.

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.

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.

Alqahtani, Mona A. published the artcileBio fabrication of silver nanoparticles with antibacterial and cytotoxic abilities using lichens, Related Products of isoquinoline, the main research area is silver nanoparticle antibacterial cytotoxic lichen biofabrication.

Recently, increase bacterial resistance to antimicrobial compounds issue constitutes a real threat to human health. One of the useful materials for bacterial control is Silver nanoparticles (AgNPs). Researchers tend to use biogenic agents to synthesize stable and safe AgNPs. The principal aim of this study was to investigate the ability of lichen in AgNPs formation and to find out their suppression ability to MDR bacteria as well as their cytotoxic activity. In the current study, lichens (Xanthoria parietina, Flavopunctelia flaventior) were collected from the south of the Kingdom of Saudi Arabia. Lichens methanolic extracts were used for conversion of Ag ions to AgNPs. Prepared biogenic AgNPs were characterized by UV-Visible (UV-Vis) Spectroscopy, Transmission electron microscopy (TEM), Dynamic Light Scattering (DLS) and Zeta potential and Energy-Dispersive X-ray Spectroscopy (EDS). Lichens Secondary metabolites were determined by Fourier-Transform IR Spectroscopy (FTIR) and Gas Chromatog.-Mass Spectrometry (GC-MS). The antibacterial activity and synergistic effect of AgNPs were evaluated against pathogenic bacteria, including gram-pos.; Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), and gram-neg.; (Pseudomonas aeruginosa, Escherichia coli) as well as the reference strains (ATCC) using the agar disk diffusion method. Cytotoxic effect of biogenic AgNPs was tested against HCT 116 (Human Colorectal Cancer cell), MDA-MB-231 (Breast cancer cell), and FaDu (Pharynx cancer cell) by MTT test. TEM imaging showed well-dispersed spherical particles of 1-40 nm size as well as zeta size showed 69-145 nm. Furthermore, FTIR and GC-MS identified various lichen chem. mols. On the other hand, the highest antibacterial activity of AgNPs was noticed against P. aeruginosa, followed by MRSA, VRE, and E. coli. AgNPs influence on gram-neg. bacteria was greater than that on gram-pos. bacteria and their synergistic effect with some antibiotics was noted against examined microbes. Moreover, higher cytotoxicity for biogenic AgNPs against FaDu and HCT 116 cell line in relation to MDA-MB-231 was noted. Given the current findings, the biogenic AgNPs mediated by lichens had pos. antibacterial, synergistic and cytotoxic powers. Therefore, they might be considered as a promising candidate to combat the multi-drug resistance organisms and some cancer cells.

Bae, Eun Jung published the artcilePeripheral Selective Oxadiazolylphenyl Alanine Derivatives as Tryptophan Hydroxylase 1 Inhibitors for Obesity and Fatty Liver Disease, Recommanded Product: 4-Methoxyphenylacetic acid, the main research area is oxadiazolylphenyl alanine derivative preparation TPH1 inhibitor obesity fatty liver.

Tryptophan hydroxylase 1 (TPH1) has been recently suggested as a promising therapeutic target for treating obesity and fatty liver disease. A new series of 1,2,4-oxadiazolylphenyl alanine derivatives were identified as TPH1 inhibitors. Among them, compound 23a was the most active in vitro, with an IC50 (half-maximal inhibitory concentration) value of 42 nM, showed good liver microsomal stability, and showed no significant inhibition of CYP and hERG. Compound 23a inhibited TPH1 in the peripheral tissue with limited BBB penetration. In high-fat diet-fed mice, 23a reduced body weight gain, body fat, and hepatic lipid accumulation. Also, 23a improved glucose intolerance and energy expenditure. Taken together, compound 23a shows promise as a therapeutic agent for the treatment of obesity and fatty liver diseases.

Sun, Lin published the artcileDesign, Synthesis, and Mechanism Study of Benzenesulfonamide-Containing Phenylalanine Derivatives as Novel HIV-1 Capsid Inhibitors with Improved Antiviral Activities, Product Details of C8H11NO, the main research area is amino acid benzenesulfonamide phenylalanine antiviral structure activity HIV1 pharmacokinetic; anti AIDS agent CA protein inhibitor MD simulation virion; mol docking hydrogen bond benzenesulfonamide phenylalanine metabolic stability; peptidomimetic peptide coupling drug design toxicity.

HIV-1 CA protein has gained remarkable attention as a promising therapeutic target for the development of new antivirals, due to its pivotal roles in HIV-1 replication (structural and regulatory). Herein, we report the design and synthesis of three series of benzenesulfonamide-containing phenylalanine derivatives obtained by further structural modifications of PF-74 to aid in the discovery of more potent and drug-like HIV-1 CA inhibitors. Structure-activity relationship studies of these compounds led to the identification of new phenylalanine derivatives with a piperazinone moiety, represented by compound (I), which exhibited anti-HIV-1NL4-3 activity 5.78-fold better than PF-74. Interestingly, I also showed anti-HIV-2ROD activity (EC50 = 31 nΜ), with almost 120 times increased potency over PF-74. However, due to the higher significance of HIV-1 as compared to HIV-2 for the human population, this manuscript focused on the mechanism of action of our compounds in the context of HIV-1. SPR studies on representative compounds confirmed CA as the binding target. The action stage determination assay demonstrated that these inhibitors exhibited antiviral activities with a dual-stage inhibition profile. The early-stage inhibitory activity of compound I was 6.25 times more potent as compared to PF-74, but appears to work via accelerating capsid core assembly rather than stabilization. However, the mechanism by which they exert their antiviral activity in the late-stage appears to be the same as PF-74 with less infectious HIV-1 virions are produced in their presence as judged p24 content studies. MD simulations provided the key rationale for the promising antiviral potency of I. Addnl., I exhibited modest increase in HLM and human plasma metabolic stabilities as compared to PF-74, as well as moderately improved pharmacokinetic profile, favorable oral bioavailability, and no acute toxicity. These studies provide insights and serves as a starting point for subsequent medicinal chem. efforts in optimizing these promising HIV inhibitors.
