The Group Allocation Multiple Access with Packet-Sensing (GAMA-PS) protocol for scheduling real-time and datagram traffic in a wireless LAN is specified and analyzed. By maintaining a dynamically-sized cycle that changes in length depending on the amount of network traffic, GAMA-PS is able to efficiently control channel access while ensuring that there are no collisions of data packets. Each cy...

L-Carnitine is used extensively in functional foods and food supplements; consequently, the control of its enantiomeric purity is of paramount importance. A new derivatization procedure and chiral gas chromatographic method with flame ionization detection, using a cyclodextrin based stationary phase, enables prompt, simple, and inexpensive screening of the enantiomeric ratio of L- and D-carniti...

This paper considers Gama-Nguyen-Regev’s strategy [4] for optimizing pruning coefficients for lattice vector enumeration. We give a table of optimized coefficients and proposes a faster method for computing near-optimized coefficients for any parameters by interpolation.

α-Interferon is an antiviral agent used in treatment of chronic hepatitis B. Triggering of the underlying autoimmune disease or exacerbation of pre-existing auto immune disease is documented with α-interferon, but there are few reports about occurrence of autoimmune disorders such as systemic lupus erythematosus, Vitiligo, hypo and hyperthyroidism after administration of α-interferon in the lit...

A diabetes é uma das doenças que se manifesta de muitas maneiras e vezes mais agressiva. Por isso, importante ressaltar o pode ser induzido por muitos medicamentos hormônios, como ácido nicotínico, propranolol, clonazepam, diuréticos tiazídicos, glicocorticoides, interferon gama, estatinas outros. Nesse ponto vista, fica clara a relevância do uso seguro racional pacientes diabéticos os possívei...

Estudos laboratoriais e clínicos sugerem a eficácia sinergismo da associação de interferon retinóides na indução regressão tumoral em uma gama variada neoplasias. No presente estudo prospectivo fase II, trinta pacientes portadores tumores sólidos avançados já refratários às modalidades terapêuticas usuais receberam ácido 13-cisretinóide, 1 mg/Kg/dia, por via oral alfa 2a, 6 MU1/m2 5 dias semana...
