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.
