The Effect of Breadfruit Leaf Extract (Artocarpus Altilis P) on Spatial Memory of in Male Strain Mice which Indicated by Alcohol

Background: Spatial memory is working memory that is used to recall when performing certain tasks which is a combination of attention, concentration, and short-term memory. Breadfruit leaves contain compounds flavonoids, tannins, saponins that are as antioxidants that can prevent cognitive disease. Purpose: This study was to determine the effect of breadfruit leaf extract on spatial memory in 10% alcohol-induced mice using the Y-Maze Methods: Method: This study used 25 mice which were divided into 5 groups, namely the Biloba Gingko positive group, the Na-CMC Negative Group and the treatment group consisted of doses of 1 10, 15, 20 mg / 20 grams BB of Mice. Every 10% alcohol-induced mice was then tested by inducing preparations according to the treatment group. The results of the time calculation on Y maze are statistically analyzed with one-way ANOVA Results: From the results of the y maze test it is known that gingko biloba gives the best effect then the treatment group with a dose of 20 mg, the group 15 mg and 10 mg, and the negative group giving Na -CMC. Conclusion: The results of this study concluded that the breadfruit leaf extract (Artocarpus altilis P) can improve the spatial memory of alcohol-induced mice 10%.

PENGARUH PEMBERIAN AIR PERASAN JERUK NIPIS (CITRUS AURANTIFOLIA SWINGLE) TERHADAP KADAR KOLESTEROL PADA MENCIT HIPERKOLESTEROLEMIA

Lime (Citrus Aurantifolia) contains of main flavonoid in limes, that is herperidin. Hesperidin can help reducing total Cholesterol level and has the property of hypercholesterolemic. Hypercholesterolemia is the main factor independent risk factor of coronary heart disease (CHD). This study intend to determine whether or not the effect od water lime extract orally with cholesterol level in the hypercholesterolemia mice. This isi an experimental study designed following randomize control design and post test only control group design by using 24 mice (Mus musculus) adult male strain DD Webster divided into 4 groups: control group (P0) that Given adlibitum, (P1) that given hypercholesterolemia 0,2 cc, (P3) that given hypercholesterolemia 0,2 cc and water lime extract 0,3 cc by gastric sonde once a day for 15 days. In the day46 mice are done neck dislocation. Data result was analyzed by One Way- Anova test and continuous and continued with post-hoc test. Result of this study showed that giving of water lime extract 0,3 cc orally per mice could reduced cholesterol level of mice hypercholesterolemia than giving water lime extract 0,1 cc orraly per mice.

Carcass and meat characteristics of male chickens between Thai indigenous compared with improved layer breeds and their crossbred

The study of carcass and meat quality of four male genotypes namely: Thai native (TH), crossbred (Thai native x Barred Plymouth Rock; THB), Barred Plymouth Rock (BPR) and Shanghai (SH) chickens was conducted. Three hundred and twenty birds receiving from four equal groups were allotted in Completely Randomized Design (CRD). They were fed from one day and slaughtered at 16 weeks of age. Breast (M. pectoralis major) and thigh (M. biceps femoris) muscles were investigated for meat quality. TH had lower slaughtered weight (P<0.001) but higher lean : bone as well as less bone percentage (P<0.05) than all groups. Thigh muscle fiber of TH had higher type I and lower type IIB whereas there were similar in breast muscle fiber. Meat quality in terms of IMF, cholesterol and triglyceride contents as well as n-3 fatty acid and the ratio of n-6/n-3 of Thai indigenous male strain was more favorable compared to those all genotypes. Breast and thigh muscle were higher in shear force value and collagen content but the sensory evaluation was not significantly different. Since they were similar in sensory evaluation, the male layer and the male crossbred chickens have the potential to substitute TH in a market serving consumers who prefer chewy chicken meat.

The disappearing danseur

ABSTRACTThe notion of studying the nineteenth-century danseur is problematic because of an anti-male strain in dance historiography that has led some to suggest that he virtually disappeared from the stage. André Levinson is largely responsible for the danseur’s poor reputation: he minimised the narrative aspect of nineteenth-century ballet and declared in 1929 that the ballerina Marie Taglioni had ‘evicted’ men from the stage. Levinson also canonised La Sylphide (1832), a ballet that he, like his nineteenth-century predecessors Théophile Gautier and Jules Janin, gendered as feminine. He promulgated the term ‘ballet blanc’, a feminising but misleading term now in common use and rarely interrogated. And yet men danced on the stage throughout the nineteenth century. In the case of the Paris Opéra, men contributed to ballet as principal dancers, soloists and in the corps de ballet. A brief study of La Jolie Fille de Gand, a ballet contemporaneous with La Sylphide, shows a rich set of male roles calling on men’s skill as mimes and dancers in various styles. Further studies of the long-maligned nineteenth-century danseur are needed.

GENETIC ANALYSIS OF A DOUBLE MALE STRAIN OF ESCHERICHIA COLI K12

ABSTRACT The behavior of a double male strain of Escherichia coli K12 has been compared to that of its parents and a primary F' strain carrying F14 in order to determine whether the genome of the double male, responsible for the double origin mode of gene transmission, is composed of one or two linkage groups. F-prime plasmids carrying leu and pyrB and argG and metC have been detected following mating an F- recA - recipient with the double male. Their existence strongly supports the contention that the double male is composed of a single linkage group with two integrated sex factors. Data from acridine orange curing experiments places the frequency of double male cells in the population of growing cells in the two-chromosome configuration as less than one percent. Evidence for a unique origin and terminus of DNA replication deduced by the density labelling and transduction of double male DNA supports the contention that the double male is best considered a cell with a single chromosome carrying two integrated F plasmids.

Genetic recombination betweenKlebsiella pneumoniaeandEnterobacter aerogenes

SUMMARYIntergeneric recombination of chromosomal genes between strains ofKlebsiella pneumoniaeandEnterobacter aerogeneshas been observed. In these experiments a male strain ofK. pneumoniaeacted as donor andE. aerogenesacted as recipient. Closely linked genes were co-transferred with very high frequency, and transfer of a large fragment carrying several separated genes was not uncommon. Subcultures of a hybrid which had received a large fragment carrying five markers were tested for genetic stability; no spontaneous segregants were found among 34000 colonies tested. These results suggest that the transferred fragment had been integrated, and indicate the close genetic relationship betweenK. pneumoniaeandE. aerogenes. This is in agreement with their very similar biochemical properties.

Observations on the fine structure of Oedogonium. VI. The striated component of the compound flagellar "roots" of O. cardiacum

The striated, inner component of the compound flagellar "roots" of zoospores and spermatozoids of Oedogonium cardiacum has been studied ultrastructurally after three methods of preparation. The roots constitute an element of the ring-shaped flagellar apparatus, with the roots and basal bodies alternating in equal numbers. Each root consists of two components radially superposed; the outer component is ribbon-like and formed of three parallel microtubular elements, while the inner component is rod-like (tapering at each extremity) and demonstrates a very regular pattern of cross-striation. Although the striated pattern in sectioned roots differed somewhat from the pattern obtained with negatively stained roots, the major periodicity in both instances averaged about 305–325 Å. This contrasts to a periodicity of 150 Å which was reported earlier. The pattern of cross-striation appears the same for roots of both spermatozoids and zoospores when any one method of preparing the material is considered separately. Furthermore, no distinctions were observed in zoospore roots obtained from a haploid male strain, a haploid female strain, and a diploid female strain. The striated root component of Oedogonium may provide mechanical support for the flagellar apparatus, thereby serving as a means for distributing throughout the motile cell the stresses generated by flagellar action. A possible contractile function cannot be excluded.
