Cardiac electrical activity imaging of patients with CRBBB or CLBBB in magnetocardiography

Chinese Physics B 2014年第4期23卷 717-722页

A new method for the imaging of cardiac electrical activity in patients with complete right bundle branch block （CRBBB） or complete left bundle branch block （CLBBB） is investigated using magnetocardiographic recordings of the surface of the body. This is based on the assumption that an equivalent single-current dipole moves along the unblocked bundle branch, whose position in the measurement plane is expressed in terms of the maximum and minimum, as well as the maximum gradient value of the measured magnetic field. The trajectory of the moving dipole on the measurement plane is indicative of theexcitation conduction of the CRBBB or CLBBB subject during ventricular depolarization and repolarization, which is deduced by comparing each change between the dipole moment and the maximum current density in a corresponding pseudo-current density map. In summary, this method can distinguish CRBBB from CLBBB subjects by means of the dipole depth and two dipole moment components. The possibility of visualizing the excitation conduction in a CRBBB or CLBBB subject during ventricular depolarization and repolarization is then discussed.

Changes in Environmental Parameters and Their Impact on Forest Growth in Northern Eurasia

Atmospheric and Climate Sciences 2015年第2期5卷 91-105页

We performed an empirical investigation of forest growth for two types of forests in northern Eurasia (larches and spruces) in order to show that the sensitivity of trees to the variable climate and geomagnetic field can be seen even under the large-scale average. The main purpose of this research was to model a forest growth rate V for each forest type on the basis of several environmental parameters influencing the tree growth in a high degree and to find the differences and similarities of the larches and spruces’ response to changing environment. We showed that V, which is related to the annual tree-ring width, could be derived from the Normalized Difference Vegetation Index (NDVI) data. Averaged yearly by species for 1982-2006, it displayed a long-term decrease (most likely related to the global climate change) as well as short-term variations with periods of 2.2, 4 and 8 years. A composite function method was used for modeling. We selected several tree growth drivers (the temperature, precipitation, insolation and the geomagnetic field intensity) that were highly correlated with V, and a function was modeled that described the behavior of V. The correlation coefficients between the derived function and experimental time series were 0.8 for larches and 0.9 for spruces. Compared with spruces, larches demonstrated higher thermo-sensitivity. A loss of tree sensitivity to temperature changes is puzzling for dendroclimatology, as a similar process might have occurred during previous periods of sharp global climate changes (as observed currently). Sensitivity of trees to geomagnetic field changes is confirmed both at long- and short-timescales. Spruces are found to be more magnetosensitive than larches.

A Look to the Bioenergetic Medicine from the Human Physiology

引用

Journal of Pharmacy and Pharmacology 2021年第1期9卷 14-20页

作者： Richard MarceloÁlvarez Orbea Ana Elena Rodríguez Cadalso Regina de Caridad Rodríguez Muñoz Viviana Silvia Rodríguez Jímenéz Marelys Calzada Jesús Manuel Cadalso Menéndez The Branch of Medical Sciences“Elena Fernández of Castro”of Trinidad Trinidad 62600Sancti SpíritusCuba

Objective: To relate biochemistry of the human physiology with the application of the bioenergetic medicine. Methods:Search about the topic in the last 5 years and present a general view of some biochemical processes that allow to apply thebioenergetic medicine, due to the need to open new alternatives based on holistic methods. Conclusions: It was based on the searchof articles in the Virtual Library in Health (Spanish: BVS) and using the key words: bioenergetic medicine, vibration, energy,breathing, chakras, biomagnetism, translated into the quality of life’s improvement and the welfare of human being.
