Hepatoprotective Effect of Moringa Oleifera Leaves Extract on Acetaminophen-Induced Liver Damage in Rats
Moringa oleifera (MO) is reported to have various medicinal properties. The aim of
this study is to evaluate the hepatoprotective effect of MO leaf extract against
acetaminophen (APAP) induced liver damage in rats. A dose of 3g/kg APAP was
selected to induce liver damage. Seventy male Sprague-Dawley rats (n=70) were
divided into seven groups. Five groups of animals were given various oral
pretreatments of 200mg/kg MO, 800mg/kg MO and 200mg/kg Silymarin (Sil) in
distilled water at 3ml/day for fourteen days. Meanwhile, two groups served as
hepatotoxicity (3g/kgAPAP) and vehicle (40% sucrose) control groups were given
distilled water in the similar manner. On day 15, the animals were challenged with
3g/kg APAP in 40% sucrose except for rats in the vehicle (40% sucrose) and MO
control groups which received 40% sucrose solution. After 24 and 48 hours blood
was withdrawn and livers were harvested. Plasma was prepared and liver function
was carried out to determine levels of alanine aminotransferase (ALT), aspartate
aminotransferase (AST) and alkaline phosphatase (ALP). Liver samples were taken
for histopathalogical examination, measurement of hepatic reduced glutathione (GSH) content, glutathione-S-transferase (GST), glutathione peroxidase (GPx) and
glutathione reductase (GR) activities as well as determining malondialdehyde
(MDA) levels. Statistical analysis was performed using analysis of variance
(ANOVA) and Kruskall Wallis analysis of variance coupled with the Mann–Whitney
U-test. APAP treatment caused significant elevation (p<0.05) of ALT, AST after 24
and 48 hours. Histopathological observations substantiated these findings showing
significant (p<0.05) liver damage. APAP treatment caused marked reduction
(p<0.05) in hepitic GSH content, GST and GPx. activities coupled with significant
increase (p< 0.05) in lipid peroxidation index. The changes observed were
time dependent with more changes were noted after 48 hours. Significant (p<0.05)
elevation of ALP and significant (p<0.05) decline of GR activity was only noted
after 48 hours compared to other groups. 200mg/kg and 800mg/kg MO extract
equally showed a significant (p<0.05) amelioration of ALT, AST and ALP levels and
a significant reduction (p<0.05) of pathological alteration in a manner similar to Sil.
MO extracts showed no signs of toxicity up to a dose level of 800 mg/kg. MO alone
significantly increased (p<0.05) GSH content and restored GSH level (p<0.05) in the
groups given MO and challenged with APAP. MO alone showed insignificant
increase of GST, Gap and GR activities. The significant increase (p<0.05) of these
antioxidant enzymes observed in groups received MO extracts and challenged with
APAP. Lipid peroxidation was significantly (p<0.05) inhibited by the extracts in
dose independent manner. A significant (p<0.05) increase of GST activities by
200mg/kg and 800mg/kg MO extracts to the level higher than vehicle group were
observed as early as 24 hours in comparison with rats given pretreatment of
Silymarin. On the other hand, 200 mg/kg MO significantly (p<0.05) showed similar
increase in GPx activity to the level higher than vehicle group in comparison with groups that given 200mg/kg Sil and 800mg/kg MO pretreatment. Prevention of
enzyme leakage, preservation of hepatocytes structural integrity, prevention of GSH
depletion, restoration of antioxidant enzymes activity that is essential in accelerating
detoxification and excretion of APAP toxic metabolites, as well inhibition of lipid
peroxidative processes reveals that the extracts of MO leaves possesses potential
hepatoprotective activity against APAP induced damage in rats
Cultural Re(production) in Maruxa Vilalta’s Pequeña historia de horror (y de amor desenfrenado)
Through the lens of Gérard Genette’s idea of transtextuality, this study looks at Maruxa Vilalta’s representation of cultural manifestations in order to question how they affect social relations. Pequeña historia de horror (y de amor desenfrenado) is analyzed as a theatrical version of “Susanna and the Elders” precisely to show Vilalta’s broader concern with cultural reproduction. This study brings to light the interconnectedness between this play and other cultural texts ranging from Chopin’s “Polonaise Heroic” to Mexican pop culture figure El Monje Loco. I thus show Vilalta’s innovative questioning of artistic value and, more importantly, its social implications through the “distorted mirror” she creates in this particular play
Performance of Silica Gel in the Role of Residual Air Drying
Removal of carbon dioxide (CO2) is a necessary step in air revitalization and is often accomplished with sorbent materials. Since moisture competes with CO2 in sorbent materials, it is necessary to remove the water first. This is typically accomplished in two stages: bulk removal and residual drying. Silica gel is used as the bulk drying material in the Carbon Dioxide Removal Assembly (CDRA) in operation on ISS. There has been some speculation that silica gel may also be capable of serving as the residual drying material. This paper will describe test apparatus and procedures for determining the performance of silica gel in residual air drying

ABSTRACT
This study entitled, “Manimbong and Ma’dandan Dance in Rambu Tuka’ Ceremony from Toraja, South Sulawesi”. Manimbong and Ma’dandan dances grow and develop in the Tana Toraja region. Manimbong and Ma’dandan dances are common in the society, yet on the other side, socially, these dances are scarce. Besides, these dances are also rare in the documentation. This study came up with the issues of the origin of Manimbong and Ma’dandan dances, the gestures, the presentation, the cosmetology, the costumes and the accompaniment of Manimbong and Ma’dandan dances. This study intended to delineate the origin of Manimbong and Ma’dandan dances, the presentation, the cosmetology, the costumes and accompaniment of Manimbong and Ma’dandan dances in Rambu Tuka’ ceremony. The descriptive analysis method was applied along with qualitative approach. The data were collected through observation, interview, documentation, literature review, and triangulation of data analysis. The results of this study showed that Manimbong and Ma’dandan dances originated from the locution of gratitude of Toraja society, for they had finished a whole set of customs in Tongkonan house. Manimbong is danced by the menfolk, whilst Ma’dandan is danced by the womenfolk. The unique characteristic of gestures from Manimbong dance is mangondo while chiming simbong. Ma’dandan dance has the very simple gestures like swinging the body to the right and the left while spinning the tekken held by the dancers. The presentation of these dances is very simple. The dancers lined up while dancing. The dressing used in this dance is the realist dressing. Dancers use Toraja traditional clothes. The accompaniment in this dance used the song sung by the dancers. To sum up this study, Manimbing and Ma’dandan dance is still preserved and this could be seen from the community tradition activities often held by Toraja society. Dressing, clothing and accompaniment still apply strong grip of tradition.

Pengelolaan Sumberdaya Ikan Bada (Rasbora sp) di Danau Maninjau, Sumatra Barat
Bada fish is one of the high economic value fish resources that live in Lake Maninjau. Overfishing of bada fish by fishermen without paying attention to aspects of fish biology can lead to population decline. This study aims to analyze the form of bada fish management by looking at its biological aspects. This research was conducted at the Limnology Research Center of the Indonesian Institute of Sciences (LIPI) Cibinong, Bogor in May-December 2019. Bada fish samples were collected from Lake Maninjau using fishing gear nets, lukah and chart. For the purposes of the analysis, the length and weight of the bada fish were measured and the level of maturity of the gonads. In this study, the t-test (partial) was carried out as an analysis of the parameters of the relationship between length and weight of fish. The results of this study indicate the growth of bada fish in Lake Maninjau based on the results of measurements of length and weight, namely length 21 mm - 124 mm with a weight of 0.01 gr - 13.85 g. The equation of the long relationship weight of female bada fish W = 3.1247L5,4128 , male bada fish W = 3.1296L5,4283 and combined W = 3.163L5,4899. The male dan female bada fish growth pattern is a positive allometric growth pattern. The value of the condition factor was obtained in female and male bada fish, namely 1.3086 and 1.0176. The highest results of bada fishing TKG III and IV were obtained in November. Therefore, it is concluded that the form of management can be carried out by limiting the size of the mesh, prohibiting the operation of non-selective fishing gear, modifying fishing gear, and regulating the catching season
