1. Comparative HPTLC analysis of bioactive marker barbaloin from in vitro and naturally grown Aloe vera
ABSTRACT Aloe vera (L.) Burm. f., Xanthorrhoeaceae, a succulent, produces barbaloin, a bioactive compounds used in various pharmaceutical products. Extracts prepared from the leaves have been widely used as bittering agents, taste modifiers and also as cathartic agent against severe constipation. Barbaloin is reported for its anti-inflammatory, anticancer, a

2. Medidas do coeficiente de multiplicação gasosa no isobutano puro / Measurements of gaseous multiplication coefficient in pure isobutane
Neste trabalho so apresentadas as medidas do coeficiente de multiplicao gasosa (α) no isobutano puro obtidas com uma cmara de placas paralelas protegida contra descargas por um eletrodo de vidro (anodo) de elevada resistividade (ρ = 2 x 1012.cm). O mtodo empregado foi o de Townsend pulsado, onde a ionizao primria produzida pela i

3. Experimental procedures for evaluating the common bean reaction to white mold / Procedimentos experimentais para avaliaÃÃo da reaÃÃo do feijoeiro ao mofo branco
The present study was carried out to determine the optimal plot size and the ideal number of repetitions in experiments using an oxalic acid solution as a method to discriminate genotypes with physiological resistance to white mold in the common bean. In addition, it was also verified if successive generations of S. sclerotiorum multiplication, in potato dex

4. Efecto de una generación de endocría sobre caracteres vegetativos y productivos en dos estructuras familiares de alcaucil
Globe artichoke (Cynara scolymus L.) is an allogamous species where vegetative propagated cultivars are not suitable for seed multiplication due to their high heterozigous condition. To obtain homogeneous materials, the inbreeding process is necessary. Inbred lines could be used as cultivars or in hybrid combinations. The effect of one generation of selfing

5. Identity Coefficients in Finite Populations. I. Evolution of Identity Coefficients in a Random Mating Diploid Dioecious Population
Properties of identity relation between genes are discussed, and a derivation of recurrent equations of identity coefficients in a random mating, diploid dioecious population is presented. Computations are run by repeated matrix multiplication. Results show that for effective population size (Ne) larger than 16 and no mutation, a given identity coefficient a

6. Differences in Response Among Inbred Mouse Strains to Infection with Small Doses of Mycobacterium bovis BCG
Intravenous infection of six inbred mouse strains with small doses of dispersed cells of Mycobacterium bovis BCG (15.5 × 103 or 15.5 × 104 colony-forming units) separated them into resistant (C3H/HeCr, A/J, and DBA/2) and sensitive (B10.A, C57BL/6, and BALB/c) strains as assessed by the magnitude of bacterial multiplication in the spleens at 28 days. The t

7. Multiplication of Polyoma Virus in Mouse-Hamster Somatic Hybrids: a Hybrid Cell Line Which Produces Viral Particles Containing Predominantly Host Deoxyribonucleic Acid
The multiplication of polyoma virus in a mouse-hamster (3T3 × BHK) somatic hybrid line (10A), which, although permissive for viral multiplication, produces very low amounts of virus, has been studied. In this cell line, the efficiency of productive infection is high, but the yield of infectious virus is on the order of 0.5% of that of 3T3 cells. The amount

8. Biochemical Studies on Adenovirus Multiplication, XIX. Resolution of Late Viral RNA Species in the Nucleus and Cytoplasm
Late after infection of cultured human cells (KB) with adenovirus type 2, the nucleus contains heterogeneous viral RNA species ranging in size from 10 to 43 S. Four viral RNA species found in the nucleus (36, 38, 40, and 43 S) are synthesized predominantly during a 15-min labeling period with [3H]uridine, while smaller RNA species accumulate when labeling is
