RESUMO

Homeopathy is controversial because using highly dilute medicines (high homeopathic potencies, HHP) beyond the Avogadro/Loschmidt limit. Previous publications [1,2] using NMR relaxation revealed the involvement of nanobubbles and/or nanoparticles and/or nanometric superstructures in high potentizations. Nano Tracking Analyse (NTA) demonstrated the presence of particles in HHPs [3,4]. WithSEM-EDX [5] we observed an ionic diversity common to all preparations including HHPs and significant differences in the relative quantity of each ion between different homeopathic manufacturing lines and controls. FTIR spectroscopy [6] shows that the molecular composition is that of carbonates, primarily sodium bicarbonate.Methods:To observe the materiality of homeopathic medicines a multidisciplinary approach is necessary. In collaboration with several universities,we canobserve these medications with NMR, NTA, SEM-EDX, FTIR, pH,and EPA. Results:The essential component of all already studied homeopathic medicines is sodium hydrogen carbonate modulated by some other elements in a specific quantity, size,and shape. The probability that the observed results could have occurred just by random chance can be rejected(significantlyabove the Avogadro limit) p < 0,001.Conclusions:The homeopathic medicines do contain material with a specific ionic composition even in HHPs diluted beyond the Avogadro/Loschmidt limit. This specificity can be attributed to the manufacturing process. These results demonstrate that the step-by-step process (dynamized or not) does not match the theoretical expectations in a dilution process. The starting material and dilution/dynamization method influencethe nature of these NPs. The role of carbonates and sodium bicarbonate must be carefully studied in the future. Its aqueous solution is alkaline in nature but itis an amphoteric compound, which means that the compound has both acidic as well as alkaline character. The reaction with acids results in sodium salts and carbonic acid and the reaction with the basic solution producescarbonates and water. Specific electric fields are indeed detectable.

RESUMO

Avaliaram-se os efeitos da substituição da monensina sódica pelo bicarbonato de sódio em dietas de novilhas em confinamento em relação ao desempenho animal, à conversão alimentar e ao parâmetro de fermentação ruminal. Foram utilizadas 56 novilhas mestiças, confinadas por 112 dias, submetidas a dietas com duas porcentagens de concentrado, 50% e 80% da matéria seca, com adição de monensina sódica ou bicarbonato de sódio, em fatorial 2x2. O volumoso utilizado para compor as dietas testadas foi composto de silagem de milho e cana-de-açúcar na proporção de 60:40, respectivamente. O nitrogênio amoniacal foi maior nos animais alimentos com dietas com alto grão. A monensina, na dieta 80:20, proporcionou maiores valores de nitrogênio amoniacal, uma e nove horas após o consumo da ração. O uso de bicarbonato promoveu os maiores valores de pH ruminal na dieta com 50% de concentrado, de seis a 18 horas após o consumo. Não houve efeito do aditivo sobre o desempenho animal. A alta inclusão de grãos na dieta propiciou aumento do desempenho animal e da eficiência alimentar. Conclui-se que o uso de bicarbonato de sódio em dietas para terminação de animais em confinamento é uma opção viável em substituição à monensina sódica para a manipulação da fermentação ruminal.


The effects of replacing monensin with sodium bicarbonate in diets for confined heifers on weight gain (WG), dry matter intake (DMI), feed:gain ratio (FGR) and rumen fermentation parameters were evaluated. Fifity six heifers were utilized (Santa Gertrudis x Braunvieh). Diets were formulated with two levels of concentrate (50% and 80% concentrate) with sodium monensin or sodium bicarbonate. The DMI was higest in heifers with an intake of 80% concentrate. There was not difference when the same concentrate levels were evaluated in relation to the DMI. The heifers at 80% concentrate showed highest WG. There was no significant difference in relation to WG between monensin and bicarbonate treatments and levels concentrate proportions. There were significant effects regarding FGR between treatments. The heifers on 80% concentrate showed lowest FGR. In the evaluation of N-NH3, the highest values were observed, on the whole, at 80:20 diets in relation to 50:50 diets. In the additive use, the monensin on 80:20 diets promoted the highest values of N-NH3 at 1 for 9 hours after feed intake. In the values of ruminal pH, the bicarbonate increased the values on 50:50 at 6 for18 hours after feed intake, in relation to the 80:20 diet. In this case, it was concluded that the use of sodium bicarbonate in diets for confined finishing heifers is a viable option for the replacement of monensin sodium.

RESUMO

Haematoxylin and eosin [H and E] is the most popular routine stain used in pathology laboratories for highlighting cellular structures. To study the effect of tap water'softening' [i.e. calcium extraction] on H and E stains, 5 sets of slides from 30 different paraffin-embedded human pathologic tissue blocks were prepared in the same way except for washing with 5 different types of water. Slides washed in untreated tap water showed the best results concerning differentiation and colour intensity, while slides washed with softened or other treated water showed poorer degrees of differentiation and colour intensity. The worst results were obtained from slides washed with water containing sodium bicarbonate. Low calcium and magnesium ions and high sodium ions in soft water adversely affect the results of routine H and E stain

RESUMO

A avaliaçäo da eficiência de dois métodos de limpeza de estruturas adesivas cimentadas com Panavia Ex (Kuraray-Osaka, Japäo) visando à recimentaçäo. Foi utilizada a chama da lâmpada a álcool para remoçäo do cimento preso à liga e comparou-se com a limpeza com jato de bicarbonato de sódio do aparelho Proli II (Dabi-Atlante-Ribeiräo Preto-SP, Brasil) sem água
