BACKGROUND The object of this study was to assess the efficay and maximum duration of effect of the pleural tent in reducing the incidence of air leak after upper lobectomy. METHODS Two hundred patients who underwent upper lobectomy were prospectively randomized into two groups: 100 patients who underwent an upper lobectomy and a pleural tent procedure (group 1; tented patients) and 100 patie...

Recently an image encryption scheme based on a chaotic Tent map has been proposed by Li et al. [1]. This comment shows that this scheme is broken and no secure application can be found for it. The recent paper by Li et al. [1] proposed a chaotic image encryption based on a Tent map and evaluated its security through statistical analyses. It is true that when an image encryption scheme is design...

Ligand-receptor complexes are internalized by a variety of endocytic mechanisms. Some are initiated within clathrin-coated membranes, whereas others involve lipid microdomains of the plasma membrane. In neurons, where alternative targeting to short- or long-range trafficking routes underpins the differential processing of synaptic vesicle components and neurotrophin receptors, the mechanism giv...

BACKGROUND The aim of the present study was to assess the cost/efficacy of the pleural tent procedure after upper lobectomy. METHODS A prospective randomized analysis was performed on 50 patients submitted to upper lobectomy and divided into two groups: group 1 (25 patients) with pleural tent; group 2 (25 patients) without pleural tent. RESULTS The univariate comparison between the two grou...

Vesicular pathways coupling the neuromuscular junction with the motor neuron soma are essential for neuronal function and survival. To characterize the organelles responsible for this long-distance crosstalk, we developed a purification strategy based on a fragment of tetanus neurotoxin (TeNT H(C)) conjugated to paramagnetic beads. This approach enabled us to identify, among other factors, the ...

− In this paper, the international data encryption algorithm is applied to design the symmetric cryptosystem based on chaotic signals. Ciphertext are masked by means of the tent map. Plaintext could be recovered to the original signals through chaos synchronization. Since the H∞ controller is robust, it can restrain effects of different initial values and variant system parameters between the t...
