BACKGROUND: Various methods are currently used to define species and are based on the phylogenetic marker 16S ribosomal RNA gene sequence, DNA-DNA hybridization and DNA GC content. However, these are restricted genetic tools and showed significant limitations. RESULTS: In this work, we describe an alternative method to build taxonomy by analyzing the pan-genome composition of different species of the Klebsiella genus. Klebsiella species are Gram-negative bacilli belonging to the large Enterobacteriaceae family...

Perception of color varies markedly between individuals because of differential expression of photopigments in retinal cones. However, it has been difficult to quantify the individual cognitive variation in colored scene and to predict its complex impacts on the behaviors. We developed a method for quantifying and visualizing information loss and gain resulting from individual differences in spectral sensitivity based on visual salience. We first modeled the visual salience for color-deficient observers, and found that the predicted losses and gains in local image salience derived from normal and color-blind models were correlated with the subjective judgment of image saliency in psychophysical experiments, i...

BACKGROUND: Allergic rhinitis (AR) presents as the main and most invasive symptom in the blocking of the nose. This condition is almost always related to hypertrophy of the inferior turbinates. When the medical treatments are found to be insufficient to solve the obstructive symptom of the patient, the quality of life is considerably impaired and it is often necessary to submit the patient to a surgical approach. In the present study we aimed to establish the efficacy and safety of a new technique recently introduced for the shrinkage of hypertrophic turbinates using a specific device, based on a new radiofrequency energy that does not produce thermal mucosal damage, viz...

Chondromas are benign cartilaginous tumors usually localized within the tubular bones of the extremities. Soft tissue chondromas (STCs) are rare and only few cases have been reported in the oral cavity. The present case documents the exceptional finding of a 12-year-standing STC of the hard palate of a 63-year-old man. The tumor measured approximately 6 cm in its larger size and it was radically excised through the use of a quantic resonance molecular (QRM) lancet. No recurrence was observed during 1-year follow-up...

The quantication of cortical surface folding is important in identifying and classifying many neurodegenerative diseases. Much work has been done to identify regional and global brain folding, and in this paper we review some of these methods, as well as propose a new method that has advantages over the existing state of art. Using our novel proposed method, we mapped the local gyrification index on the cortical surface for subjects with mild Alzheimer's dementia (n=20) , very mild dementia (n=23) and age-matched healthy subjects (n=52)...

In this article, the pattern learned from the classic or conventional rotating circular genetic code is transferred to a 64-grid model. In this non-static representation, the codons for the same amino acid within each quadrant could be exchanged, wobbling or rotating in a quantic way similar to the electrons within an atomic orbit. Represented in this 64-grid format are the three rules of variation encompassing 4, 2, or 1 quadrant, respectively: 1) same position in four quadrants for the essential hydrophobic amino acids that have U at the center, 2) same or contiguous position for the same or related amino acids in two quadrants, and 3) equivalent amino acids within one quadrant...

Recognition of three-dimensional objects independent of size, position, and orientation is an important and difficult problem of scene analysis. The use of three-dimensional moment invariants is proposed as a solution. The generalization of the results of two-dimensional moment invariants which had linked two-dimensional moments to binary quantics is done by linking three-dimensional moments to ternary quantics. The existence and number of nth order moments in two and three dimensions is explored. Algebraic invariants of several ternary forms under different orthogonal transformations are derived by using the invariant property of coefficients of ternary forms...

1. The photochemical theories of vision cannot provide a valid interpretation of the facts over the whole range of brightness. The fact that liminal excitation is increased by the absorption of a very small number of quanta, each absorbing rod receiving a single quantum, excludes the intervention of the mass action law which is the basis of all photochemical theories. 2. Owing to the quantic structure of light and to the random distribution of quanta in a faint light pencil, there must exist numerical relations between the threshold energy on the one hand and the size of the retinal area stimulated and the stimulation time on the other, whatever may be the inner mechanism of liminal excitation...

Quantic molecular resonance is a new technique that applies high frequency waves suitable for many surgical fields. It is a remarkable advance from conventional electrosurgery, and consists of non-traumatic cutting of tissue and gentle coagulation. The cut is achieved by the explosion of infracellular and intracellular liquids, that resonate with a special frequency. The temperature of the cut area and surrounding tissues is less than 45 degrees C, so no thermal injury results. Coagulation is by denaturation of fibrinogen at 63 degrees C, and not at (conventional) higher temperatures...

A rapid and accurate reversed-phase liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method has been developed and validated for the quantitative determination of five flavonoid glycosides, icariin, epimedin A, epimedin B, epimedin C and hyperin in Herba Epimedii. Chromatographic separations were performed using a C(18) narrow-bore HPLC column; a mixture of an aqueous solution of ammonium formate (pH 4.0) and acetonitrile was used as the mobile phase, with compounds detected in the positive ion mode with multiple-reaction monitoring using a triple-quadrupole mass spectrometer equipped with an electrospray ionisation interface...

Lead reaction with oxygen and ozone molecules is of a great importance for the study of the impact of this metal in the atmosphere medium. Stable species, intermediates, and transition states of possible resulting complexes have been studied with the three parameter hybrid B3LYP exchange-correlation DFT method, and coupled cluster with single, double, and triple excitation methods. Geometry, and spectroscopic and thermodynamic properties obtained for the different species are presented, discussed, and compared to available experimental data...

This study was aimed to establish a rabbit model of bridging artery defect with autogenous vein under equal arterial and venous compliances by selecting an appropriate anastomosing tension based on assessing the influence of vessel's longitudinal strain on compliance. The exponential form P = M1 x [eM2(v-v0)-1] was employed to fit the blood pressure-unit volume curves under different stretch ratios(lambda) obtained from real curves on 13 femoral arteries and 12 veins whose uniaxial loading tests at longitudinal directions had been performed, then the quantic M = a1 lambda 5 + a2 lambda 4 + a3 lambda 3 + a lambda 2 + a5 lambda + a6 was done to fit M-lambda data...

We consider quantum nonlinear many-body systems with dissipation described within the Caldeira-Leggett model, i.e., by a nonlocal action in the path integral for the density matrix. Approximate classical-like formulas for thermodynamic quantities are derived for the case of many degrees of freedom, with general kinetic and dissipative quadratic forms. The underlying scheme is the pure-quantum self-consistent harmonic approximation (PQSCHA), equivalent to the variational approach by the Feynman-Jensen inequality with a suitable quadratic nonlocal trial action...
