 Salicylic Acid Prevents the Deleterious Impact of Salt Stress on Vigna Unguiculata L.

ABSTRACT: Plant growth was reduced significantly by salt stress which is a serious environmental problem. Plants have different metabolites that are working in response of different biotic and abiotic stresses and salicylic acid is one of them that act as a vital compound in plants for response against different environmental stresses and modifications and it has also an important role in declining damages in plants that are caused by different stresses. Present project was designed to explore the same phenomenon of salicylic acid on Vignaunguiculata irrigated with different sea-salt concentrations. So, Vignaunguiculata seeds were grown in pots containing loamy soil in field conditions. Sea-salt concentration(0, 2.5 dS/m and 5 dS/m) and salicylic acid levels(0, 0.5mM and 1mM) were used in this experiment which is complete randomized design (CRD) and factorial experiment. Present investigation revealed reduction in root length, plant height, total fresh biomass, total dry biomass, relative water content (RWC), photosynthetic pigments(chlorophyll a, b, total chlorophyll) and proteins while increase in total carbohydrates as salt concentration increased. Results regarding presence of ions in different parts of plant showed that sodium ion level showed increase while potassium ion level showed decrease in different plant parts as sea salt concentration increased in irrigation water. Different doses of salicylic acid exhibited improvement in studied parameters under non-stressed and stresses environment.

 Plants Traditional Medication in Arid and Semi-Arid Zone of Tehsil Domel, District Bannu, Khyber Pakhtunkhwa–Pakistan

 ABSTRACT: The Indigenous communities of tehsil Domel, District Bannu, Khyber Pakhtunkhwa, Pakistan, mainly depend on ethnomedicinal plants, and the study was conducted with the aim to document therapeutic plants and formulae used by the local people for the treatment of different human infirmities. Ethnobotanical data was obtained by conducting many field trips, questionnaires, open-end and semi structured interviews, inquiries, and group gathering from 2016 to 2017.To evaluate the reliability and richness of herbal knowledge, the data were investigated using quantitative Ethnomedicinal indicex Relative Frequency Citation (RFC), Use Value (UV), respectively. During the survey, 49 species of medicinal plants belonging to 28 botanical families were reported to be used in traditional medicines. Lamiaceae and Solanaceae with 6 species are the dominant families, followed by Moraceae and Fabaceae. With regard to growth form, the main source of herbal medicines was herbs (47%). For remedy preparation, leaf (36%) was the most frequently utilized part. Moreover, 25% of the herbal medicines were prepared in the form of Powder and administered orally. The different plant species used by the local people in large numbers for medicinal purposes indicated that tehsil Domel is wealthy in medicinal flora and allied traditional knowledge. This shows that the indigenous people still rely on therapeutic plants for their healthcare needs, and therapeutic plants are the chief source for plants-based medicines for the inhabitants of the study area. A comprehensive data were found on general and worldwide uses of the proposed study to extract new potential species for further ethnomedicinal and/or ethnopharmacological, Phytochemical, and clinical studies.

 Inhibition of Patulin-Induced Oxidative Stress in Human Esophageal Epithelial Cells by 3, 3’-Diindolylmethane

 ABSTRACT: To understand the effects of 3,3’-diindolylmethane on oxidative stress induced by patulin in HET-1A human esophageal epithelial cells and the underlying mechanism. HET-1A cells were treated with patulin to establish an oxidative stress model. The results of the CCK-8 assay indicated that low dose of DIM shows no obviously toxic effects on the HET-1A cells. Flow cytometric analysis indicated that DIM could inhibit patulin-induced ROS production in the HET-1A cells. The Western Blotting results showed that the protein expression of phospho-p38 MAPK and phospho-SAPK in the HET-1A cells gradually decreased; In addition, phospho-NF-kB expression also decreased significantly. It can be concluded that the underlying mechanism of DIM reduced the patulin-induced oxidative stress in HET-1A cells might be the inhibition of ROS production and regulation oxidative stress-related proteins such as NF-kB and the MAPK family. These results indicated that DIM might be categorized as an effective drug for treating or delaying the injury of esophageal epithelial cells due to oxidative stress.

 Housing Adjustment Phenomena in the Coastal Area of Muara Angke, North Jakarta, Indonesia

 ABSTRACT: In the early 1970s, the Government of Jakarta developed Muara Angke, a delta located at the north coast of the city as a new settlement to accommodate housing facilities for the local fishery community members. Muara Angke was an area vulnerable to flooding. During the year 1977 to 2012, ten significant floods had occurred at Muara Angke, causing damages to people’s houses and degrading the quality of their lives. Consequently, from time to time the residents had to adjust their houses and surrounding environments to overcome the critical conditions. The objective of this study wasto investigate the housing adjustments made by the residents in response to the threat of flood.This research was carried out using interview and field observation methods. Four housing blocks in Muara Angke, namely block H, L, K and Bermis were selected as the objects of study.120 households were purposefully selected as respondents, to represent each housing block or sub-population proportionately. The research findings show that the flood incidents had forced the residents to 1) raise the elevation of the ground floor, to avoid water intrusion into their houses, and hence to prevent any damage to the exterior as well as the interior of the house. 2) heighten the ceiling clearance, to anticipate the effect of land subsidence for many years to come. 3) build additional floor levels as family refuge area in case a flood incident occurred. Also, depending on their financial ability, the residents increase the level of privacy and improve the physical standard of their living space, by 1) expanding floor area, 2) improving spatial configuration, and 3) adding income generating unit such as rental rooms and small-shop.
