Structural and thermal analyses of zinc and lactose in homeopathic triturated systems.

Structural and thermal analyses of zinc and lactose in homeopathic triturated systems. Homeopathy. 2017 Aug;106(3):160-170 Authors: Holandino C, Oliveira AP, Homsani F, de Paiva JP, Barbosa GM, de Lima Zanetti MR, de Barros Fernandes T, Siqueira CM, da Veiga VF, Coli Louvisse de Abreu L, Marzotto M, Bernardi P, Bonamin LV, Bellavite P, Rossi AL, Picciani PHS Abstract BACKGROUND: A series of different experimental approaches was applied in Zincum metallicum (Zinc met.) samples and lactose controls. Experiments were designed to elucidate the effect of zinc trituration and dynamization on physicochemical properties of homeopathic formulations, using lactose as excipient. METHODS: Zinc met. potencies (Zinc met 1-3c) were triturated and dynamized using lactose as excipient, according to Brazilian Homeopathic Pharmacopoeia. Lactose samples (LAC 1-3c) were also prepared following the same protocol and used as controls. The samples were analyzed structurally by Atomic Absorption Spectroscopy (AAS), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) with Energy Dispersive X-ray Spectroscopy (EDX) and Scanning Electron Microscopy (SEM), and thermodynamically by Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC). RESULTS: AAS analysis detected 97.0 % of zinc in the raw material, 0.75 % (Zinc met 1c) and 0.02% (Zinc met 2c). XRD analysis showed that inter-atomic crystalline spacing of lactose was not modified by dynamization. Am...

CONCLUSIONS: Novel BL/BLIs are not inferior to other available antibiotics for the treatment of cIAI, and they have advantages in patients with cUTI. Simultaneously, they are sensitive to Gram-negative pathogens, especially E.coli and K.pneumoniae. PMID: 29343141 [PubMed - as supplied by publisher]

CONCLUSION: EBV cannot be considered as a microbiologic marker of peri-implantitis. However, EBV could be considered as a risk factor and a peri-implantitis enhancer based on its positive correlations with pathogens associated with peri-implantitis. PMID: 29340343 [PubMed - in process]

This study shows that STEC of different serotypes and genotypes circulate in the city of La Plata and surroundings. Despite the genetic diversity observed between the O157:H7 isolates, some were indistinguishable by the subtyping techniques used. PMID: 29336911 [PubMed - as supplied by publisher]

In this study, E. coli O157: H7 was treated with slightly acidic electrolyzed water (SAEW), acidic electrolyzed water (AEW) and sodium hypochlorite with different available chlorine concentrations (ACC). The reduction of population was determined, as well as the status of treated cells (viable and culturable, VBNC, dead) was assayed using flow cytometry combined with plate counting. Finally, the cell which cannot be detected using routine media was cultured in p-TSB to resuscitate. The results showed that the reduction of E. coli O157: H7 increased with increasing ACC of SAEW, AEW and sodium hypochlorite and the ...

Total and fecal coliforms were enumerated and selected Enterobacteriaceae colonies were identified. Escherichia coli (E. coli) and Salmonella isolates were serotyped, after which their antimicrobial susceptibility patterns were deter...

ConclusionThis study clarified differences in the relative proportions of primary diseases between patients from Japan and North America and Europe. The difference may be attributable to the lower estimated incidence of STEC-HUS in Japan.

AbstractAnaplasma marginale (A. marginale) has a remarkable impact on livestock production, and an effective vaccine is not currently available due to the inexistence of a small animal model. Recently, BALB/c mice were successfully infected withA. marginale, resulting in an acute and persistent anaplasmosis infection. Here, we designed a hybrid protein containing repeats of polypeptide 1a from major surface protein-1 complex (MSP1a) repeats and common epitopes of outer membrane proteins (OMPs) OMP7, OMP8 and OMP9 expressed inEscherichia coli. Our proof-of-concept assessed vaccinal effectiveness against a challenge with liv...

Lioy, Axel Cournac, Martial Marbouty, Stéphane Duigou, Julien Mozziconacci, Olivier Espéli, Frédéric Boccard, Romain Koszul As in eukaryotes, bacterial genomes are not randomly folded. Bacterial genetic information is generally carried on a circular chromosome with a single origin of replication from which two replication forks proceed bidirectionally toward the opposite terminus region. Here, we investigate the higher-order architecture of the Escherichia coli genome, showing its partition into two structural...
