The algebraic structures of the genetic code are most important to obtain additional information about the semantic code and its applications. In this paper we define two dual Boolean codon lattices of the genetic code using hydrogen bond numbers and the chemical types of bases: purines and pyrimidines. The Boolean lattices reflect the role of hydrophobicity in the distribution of codon assignm...

With today's development of information technology comes the increased development of numerous real-time multimedia network applications. Some examples include video and tele-conferencing, tele-medicine, video-on-demand, distance education, applications in finance, etc. Several of these applications require multicasting with a certain Quality of Service (QoS). One of the most important QoS para...

E-mail address: [email protected] ABSTRACT Introduction: Cardiovascular diseases are one of the leading causes of death worldwide, among this group, acute myocardial infarction accounts for a large number of cases. Objective: To characterize the clinical features of patients who died from acute...

1. The effects of safrole and isosafrole pretreatment on both N- and ring-hydroxylation of 2-acetamidofluorene were studied in male rats and hamsters. 2. Isosafrole (100mg/day per kg body wt.) pretreatment of rats for 3 days did not have any effect on urinary excretion of hydroxy metabolites of 2-acetamidofluorene. However, similar pretreatment with safrole produced increased urinary excretion ...

A greenhouse experiment on a silt loam surface soil (Typic Hapludult) was done to investigate effects of P and S on yield, quality aspects and sugar reserves in the tropical forage legume Clitoria ternatea L. Four levels of P and two N treatments (NH4N03 vs symbiotic) were arranged in a factorial design with four replications. After the first cutting two levels of S were imposed on this design....

A new n-dimensional vector space of the DNA sequences on the Galois field of the 64 codons (GF(64)) is proposed. In this vector space gene mutations can be considered linear transformations or translations of the wild type gene. In particular, the set of translations that preserve the chemical type of the third base position in the codon is a subgroup which describes the most frequent mutations...

AIMS AND METHOD The aim of this literature analysis was to establish the range of doses of haloperidol decanoate effective in preventing relapse in schizophrenia. Studies reporting relapse rates in patients treated for longer than 6 months were included. Relapse rate was then plotted against dose or log dose to allow drawing of dose-response curves. RESULTS Fifteen publications reporting 13 ind...

Background. Class IC antiarrhythmic drugs (IC-AADs) are recommended as first-line therapy in treatment of lone paroxysmal atrial fibrillation (AF) along with catheter ablation pulmonary veins. Despite previous attempts to identify predictors IC-AADs` efficacy, the choice between IC-AADs agents is still most often carried out using empirical approach.Aim. To determine ` efficacy patients AF abse...

Two roles hypothesized for surface characteristics, such as color, brightness, and texture, in object recognition are that such information can (a) define the gradients needed for a 2%-D sketch so that a 3-D representation can be derived (e.g., Marr & Nishihara, 1978) and (b) provide additional distinctive features for accessing memory. In a series of five experiments, subjects either named or ...
