Axillary Brachial Plexus Block
Ashish R. Satapathy,David M. Coventry
Anesthesiology Research and Practice , 2011, DOI: 10.1155/2011/173796
Abstract: The axillary approach to brachial plexus blockade provides satisfactory anaesthesia for elbow, forearm, and hand surgery and also provides reliable cutaneous anaesthesia of the inner upper arm including the medial cutaneous nerve of arm and intercostobrachial nerve, areas often missed with other approaches. In addition, the axillary approach remains the safest of the four main options, as it does not risk blockade of the phrenic nerve, nor does it have the potential to cause pneumothorax, making it an ideal option for day case surgery. Historically, single-injection techniques have not provided reliable blockade in the musculocutaneous and radial nerve territories, but success rates have greatly improved with multiple-injection techniques whether using nerve stimulation or ultrasound guidance. Complete, reliable, rapid, and safe blockade of the arm is now achievable, and the paper summarizes the current position with particular reference to ultrasound guidance. 1. Introduction The axillary approach to brachial plexus was first demonstrated in 1884 by William Halsted when he injected cocaine under direct vision [1]. In 1911, G. Hirschel performed the first percutaneous axillary block [2]. It was only after Burnham’s publication in 1959 [3] that this block gained popularity among anaesthetists. Since then, it has become the most used peripheral nerve block for forearm and hand surgery, especially due the low incidence of complications compared to the more proximal approaches to the brachial plexus. 2. The Brachial Plexus in the Axilla [4] The brachial plexus supplies the nerve supply to the upper limb and is formed by the ventral rami of the lower four cervical nerves and the first thoracic nerve. It consists of roots, trunks, divisions, and cords. The roots are arranged between the scalenus anterior and medius muscles, and they combine in the posterior triangle to form three trunks: upper, middle, and lower. On approaching the clavicle, each of the three trunks divides into an anterior and posterior division to supply the flexor and extensor compartments of the arm, respectively. Anterior divisions of the upper and middle trunk unite to form the lateral cord, anterior division of the lower trunk continues as the medial cord, and posterior divisions of all the three trunks assemble to from the posterior cord. The three cords enter the axilla at the apex and are arranged, according to the names, around the second and third parts of the axillary artery. In relation to the first part of the artery, however, the lateral and posterior cords are lateral, and

Abstract: Quantum Cryptography or Quantum key distribution (QKD) is a technique to securely distribute a bit string,among two parties by using laws of quantum mechanics. Its security relies on foundations of quantummechanics, where as classical cryptography relies on difficulty of certain mathematical problems that can not able to provide unconditional security. Progress of research in this field indicates that QKD will be available outside the laboratory within next few years. These devices have now become complex and more effort isneeded for their verification. In this paper, we will use the PRISM tool to analyze the security of BB84 protocol and more specifically the property of eavesdropping detection by combining the parameters of quantum channel and power of eavesdropper.

Finding the optimal number of clusters has remained to be a challenging problem in data mining research community. Several approaches have been suggested which include evolutionary computation techniques like genetic algorithm, particle swarm optimization, differential evolution etc. for addressing this issue. Many variants of the hybridization of these approaches also have been tried by researchers. However, the number of optimal clusters and the computational efficiency has still remained open for further research. In this paper, a new optimization technique known as “Teaching-Learning-Based Optimization” (TLBO) is implemented for automatic clustering of large unlabeled data sets. In contrast to most of the existing clustering techniques, the proposed algorithm requires no prior knowledge of the data to be classified rather it determines the optimal number of partitions of the data “on the run”. The new AUTO-TLBO algorithms are evaluated on benchmark datasets (collected from UCI machine repository) and performance comparisons are made with some well-known clustering algorithms. Results show that AUTO-TLBO clustering techniques have much potential in terms of comparative results and time of computations.

Sapogenin mixture and pentahydroxy-pregn-14-ol, 20-one -β-D-thevetopyranoside isolated from Wattakaka volubilis induce caspase-3-dependent apoptosis in human colon cancer cells in vitro

Abstract: Summary : Sapogenins are naturally occuring metabolites associated with several health benefits. The objective was to isolate the sapogenin mixture, pentahydroxy-pregn-14-ol, 20-one -β-D-thevetopyranoside (PPG) from Wattakaka volubilis and to assess their anti-inflammatory and apoptotic mechanism in human colon cancer cells in vitro. Sapogenins (WVSM) and pentahydroxy-pregn-14-ol, 20-one -β-D-thevetopyranoside (PPG) are isolated from Wattakaka volubilis. The WVSM and PPG were subjected to cytotoxic assay (MTT), apoptotic parameters such as caspase-3 assay and DNA fragmentation studies against HT-29 cells. Macrophage cell line RAW 264.7 were used to process anti-inflammatory studies includes COX-2 and iNOS assay, NO and PGE2 production. WVSM and PPG showed 62 and 52% cytotoxicity against HT-29 cells, caspase-3 enzyme was increased and DNA fragmentation was showed in HT-29 cells treated with WVSM and PPG. COX-2 and iNOS activity was significantly decreased with the less production of PGE2 and NO. From the present study it can be inferred that WVSM and PPG promotes cytotoxicity against HT-29 cells with the activation of apoptotic mediators. It also promotes the anti-inflammatory activity via COX-2 and iNOS inhibition. Hence the results support the traditional use of Wattakaka volubilis against various cancers. Industrial Relevance: Globally greater than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. As of 2008 it is the second most common cause of cancer in women and the third most common in men with it being the fourth most common cause of cancer death after lung, stomach, and liver cancer. It is more common in developed than developing countries. Wattakaka volubilis prevent colorectal carcinogenesis by inhibiting the cell growth and suppressing inflammation. Hence PPG isolated from Wattakaka volubilis could be used as a potent agent to cure this ailment. Keywords : Sapogenins; pentahydroxy-pregn-14-ol; 20-one -β-D-thevetopyranoside (PPG); Caspase-3; DNA fragmentation; COX-2; INOS.
Enhancement of nonvolatile polarization and pyroelectric sensitivity in Lithium tantalate (LT)/ Poly (vinylidene fluoride) (PVDF) nano composite
S. Satapathy,P. K. Gupta,K. B. R. Varma
Physics , 2008, DOI: 10.1088/0022-3727/42/5/055402
Abstract: For pyroelectric sensor application, materials having large ferroelectric polarization at low applied field and high pyroelectric sensitivity are required. PVDF is one of the ferroelectric polymers, which is being used for pyroelectric detector application. Following properties of PVDF such as low density, low acoustic impedance, wide bandwidth, flexibility, toughness, and ease of fabrication into complex patterns and arrays make it suitable for large area detector applications. But the PVDF has low value of pyroelectric coefficient (p). High field (above 1200kV/cm) is required to pole the PVDF film. To reduce poling field and to get high value of ferroelectric polarization at low poling field, nano composite films of LT/PVDF have been prepared. Since LT is ferroelectric (max. poling field ~ 200kV/cm and (p) ~ 2.3 * 10-8 C cm-2/ K) in nature, the nonvolatile polarization of composite increased from 0.014microC/cm2 to 2.06microC/cm2 at an applied field of 150kV/cm as the volume fraction of LT (fLT) nano particle increases from 0.0 to 0.17. Similarly the increase of fLT from 0.0 to 0.17 results in increase of pyroelectric voltage sensitivity from 3.93 V/J to 18.5V/J.

Olanzapine induced tardive dystonia
Aggarwal Ashish,Jiloha R
Indian Journal of Pharmacology , 2008,
Abstract: Advent of atypical antipsychotics was thought to be a major advancement in the psychopharmacology for schizophrenia. It was thought that these drugs would have low propensity to induce extrapyramidal symptoms including tardive movements. Olanzapine is a thienobenzodiazepine derivative, second generation (atypical) antipsychotic agent. Compared to typical antipsychotics, it has a greater affinity for serotonin 5-HT2A than dopamine D2 receptors, with preferential action at mesolimbic than nigrostriatal dopaminergic pathways. However, only few reports of olanzapine induced tardive dystonia (TD) are available in the literature. We wish to report another case of TD, in a male patient with schizophrenia, which developed after 15 months of treatment with olanzapine.
