We investigated the relationship between slow axonal transport and axonal regeneration in the rat dorsal root ganglion (DRG) cell. The DRG cell sends out a single axon which bifurcates within the ganglion; one axon proceeds centrally into the spinal cord and the other proceeds peripherally. The rate of axonal regeneration is approximately 2 times faster for the peripheral processes (4.6 +/- 0.9...

The axonal transport of the diverse isotubulins in the motor axons of the rat sciatic nerve was studied by two-dimensional polyacrylamide gel electrophoresis after intraspinal injection of [35S]methionine. 3 wk after injection, the nerve segments carrying the labeled axonal proteins of the slow components a (SCa) and b (SCb) of axonal transport were homogenized in a cytoskeleton-stabilizing buf...

We construct a mathematical model for the polymerase chain reaction and its mutations using the theory of branching processes. Under this model we study the number of mutations in a randomly chosen sequence after n PCR cycles. A method for estimating the mutation is proposed and the variance of this estimator is studied. We also study the distribution of the Hamming distance between two randoml...

BACKGROUND EBUS guided trans-bronchial biopsy became routine in diagnosis of peripheral pulmonary lesions (PPL). Suction catheter-biopsy is a technique for obtaining a tissue sample from peripheral lung parenchyma. Aim of this study was to evaluate diagnostic efficiency, feasibility and safety of EBUS guided suction catheter-biopsy (SCB) in comparison to trans-bronchial biopsy (TBB) in diagnosi...

Calmodulin is a soluble, heat-stable protein which has been shown to modulate both membrane-bound and soluble enzymes, but relatively little has been known about the in vivo associations of calmodulin. A 17,000-dalton heat-stable protein was found to move in axonal transport in the guinea pig visual system with the proteins of slow component b (SCb; 2 mm/d) along with actin and the bulk of the ...

The present study highlights a range of surface and volume extrudate patterns that can be detected during the extrusion flow long-chain branched polymers. Thus, four linear low-density polyethylenes (LDPEs) have been extruded using single-screw extruder coupled to an inline optical imaging system. selected LDPEs are outline influence molecular weight branching on types melt instabilities (MFEI)...

To achieve semantic security, symmetric encryption schemes classically require ciphertext expansion. In this paper we provide a means to security while preserving the length of messages at cost mildly sacrificing correctness. Concretely, propose new scheme that can be interpreted as secure alternative (or wrapper around) plain Electronic Codebook (ECB) mode encryption, and for reason name it Se...

Charge oscillations in certain nanodevices, more specifically the so-called Superconducting Cooper Pair Boxes (SCB), are usually interpreted as an effect of macroscopic quantum coherence; an alternative explanation is however possible in terms of the Gross-Pitaewski equation for the classical order parameter. These two explanations are based on different quantum states assigned to the SCB, occu...

Hot water (HW), green liquor (GL), and sodium chlorite (SC) pretreatments were used to pretreat sugarcane bagasse (SCB) spruce (SP) then prepare cellulose nanofibers (CNFs) through high-pressure homogenization explore the effect of physicochemical properties on thermal stability ultraviolet (UV) resistance performance CNF films. The results indicated that lignin content HW-pretreated CNFs was h...

We look into nonparametric regression with repeated measurements collected on a fine grid. An asymptotic normality result is obtained in a function space equipped with the supremum norm. This result can be used to build simultaneous confidence bands (SCB) for various tasks in statistical exploration, estimation and inference. Two applications are proposed: one is a SCB procedure for the regress...
