Irrational use of Medicines is a global phenomenon. Various studies
conducted in developed as well as in developing countries during past few years
regarding the safe & effective use of drugs show that irrational drug use is a global
phenomenon & only few prescriptions justify rational use of drugs. Rational use of
medicines requires that "patients receive medications appropriate to their clinical
needs, in doses that meet their own individual requirements, for an adequate period of
time, and at the lowest cost to them and their community".

Microalgae represent the main source of biomass production in an aquatic
ecosystem which also possess system for generation and elimination of reactive
oxygen species (ROS). Marine water receives increased number of anthropogenic
chemicals from point and non-point sources. ROS concentration is dynamic in nature,
that enhanced by the chemical sources in the marine environment and later it induces
the oxidative stress in the marine organisms such as microalgae. In order to
understand ROS changes with respect to seasonal fluctuation of marine pollutants and
their impact on microalgal communities, two regions of Southeast coast of India were
selected i.e., Tuticorin – a pollution impact site and Rameshwaram – the reference
site. In this study microalgae distribution during three seasons i.e., summer, monsoon
and winter were analysed. Quantification of physiochemical and heavy metal ions
were analysed. ROS such as superoxide radical, hydrogen peroxide and hydroxyl
radicals were measured using Electron Spin Resonance. Species richness, dominance
and cell density of microalgae were calculated. All season data analysis showed
significant reduction of species distribution and diversity in both sites. The species
richness i.e Shannon- wiener diversity was high in the reference site, where as the
dominance simpson diversity was high in impact size showed that the pollutants
decreased the richness increase the dominance of some microalgal species.
Correlation between the chemical parameter and microalgal distribution showed that
the physiochemical parameters like Alkalinity, Phosphorus, Nitrogen compounds,
BOD, DO were determined the microalgal density, species richness and dominance in
both sites. Dynamic changes of heavy metals ions such as Hg, Cd, Cr, Fe, Zn and Al
with the other marine in an chemicals impact site during different season’s sites
enhance the ROS production. It was found that the micro algal communities were
highly affected by chemicals in polluted marine water and that could enhance the
oxidative stress.

In aquatic ecosystems, metal concentrations are monitored by measuring
the levels in fish, water and sediments. Contribution of heavy metals in the water
bodies include industrial effluents, fossil fuels burning, agricultural runoffs,
geological weathering domestic waste and human and animal excretions. Water,
sediment and fish samples from the river were used to assess the levels of heavy
metals concentration in the river. The objective of this study was to measure the
concentration of levels of the heavy metals (Cd, Co, Cr, Zn, Pb, Cu, Fe, Mn and Ni)
in samples of water, fish (Oreochromis niloticus) and sediments from Afram River.
Heavy metal concentration and selected physicochemical parameters (Electrical
conductivity, Temperature, TDS and pH) of the water samples were determined.
Levels of the heavy metals (Cd, Co, Cr, Zn, Pb, Cu, Fe, Mn and Ni) in water, fish
(Oreochromis niloticus) and sediments from Afram River were determined using
VARIAN AA 240FS-Atomic Absorption Spectrometer in an acetylene- air flame. In
the fish (Oreochromis niloticus) samples, the highest concentrations of 50.46 mg/kg,
34.18 mg/kg, and 15.60 mg/kg were recorded for the metal Fe in the fish gills, bones
and muscles respectively whereas the lowest concentration of < 0.08 mg/kg was
recorded for the metal Cd in the gills, bones and muscle.

A total of seventy five (75) marine fishes comprising eight (8) species were
collected from local wholesale markets at Kaneshie and Abeka, Accra, Ghana. The
samples obtained from Kaneshie market were Salmon salar (Salmon), Thunnus
obesus (Tuna), Scomber scombrus(Atlantic mackerel) and Clupea harengus (Atlantic
herring) and those obtained from Abeka market were Centroberyx affinis (Red fish),
Merluccus paradoxas(Hake fish), Scomber trachurus (Atlantic horse mackerel) and
Melanogrammus aeglefinus(Haddock). Mercury concentrations in the muscle and
liver tissues were determined by cold vapour atomic absorption spectrophotometry
using a semi-automated mercury analyzer. Mean mercury concentrations in the
muscle ranged from 0.06 to 0.33 µg g-1 wet weight, with Thunnus obesus having the
highest followed by Merluccus paradoxas which are all predatory fishes. Mean
mercury concentration in the liver tissue ranged from 0.06 to 0.34 µg g-1 wet weight,
with Thunnus obesus having the highest followed by Melanogrammus aeglefinus.
There was no significant difference between mercury concentrations in the muscle
and liver tissues for any of the samples. Low levels of mercury were found in both
tissues for all the samples. Mercury concentrations were relatively greater in the
tissues of higher trophic level fish such as Thunnus obesus, Merluccus paradoxas and
Melanogrammus aeglefinus whereas low trophic level fishes recorded low mercury
concentrations. The results obtained for total mercury concentration in the muscles
analyzed in this study were below the WHO/FAO threshold limit of 0.5µg/g wet
weight, which suggest that the exposure of the general public to mercury through fish
consumption can be considered negligible.

The establishment of offshore aquaculture production areas that compete
with traditional fishing activities is a potential source of conflict that needs to be
assessed in coastal areas. Having little specific data available on the impacts of these
farms, we aimed, through the present study, to gather information on this issue,
especially regarding Monastir bay, a major zone of aquaculture production in the
eastern shore of Tunisia. Hence, we have surveyed fishers‟ observations through a
questionnaire-based methodology. A total of 78 fishermen were interviewed, in
December 2016, in three different ports: Monastir, Sayada and Teboulba. Results
revealed that 77 % of local fishing communities complained about the loss of fishing
grounds and changes in the quantity and quality of catches. Net damage, caused by
dolphin predation, was reported by 31% of fishermen. The most abundant and
dominant fish and mollusc species around fish farms, as reported by 30% of inquired
fishermen, were Mugil cephalus, Octopus vulgaris and Sardinella aurita, while 15%
of fishermen interviewed reported the presence of marine turtles near cage fish farms.
The present survey already provides an important data platform that will be useful to
decision makers, to adopt appropriate strategies allowing harmonious coexistence
between fish farms and fishing activities, in order to ensure ecological sustainability.

Institutionalization during old age requires tremendous adaptability.
Reminiscence therapy has proven to be among the most effective at minimizing these
outcomes. Loneliness, anxiety, and depression are common problems for older adults
in long-term care. Reminiscence therapy is a non- pharmacological intervention that
may be of some benefit. In comparison to individual reminiscence therapy, group
reminiscence therapy is a preferred option when dealing with the resource constraints
of long-term care. The current study aims to understand the researcher has done an
extensive literature review to understand in depth concepts and ideas about
Reminiscence Therapy on Depression among the elderly. The objective of this
systematic review is to provide healthcare professionals with information to assist in
their decision to utilize reminiscence therapy for depression reduction in older adults
outside of the primary care setting. Reviewed studies that were randomized controlled
trials not only varied in person, outcome measurement, control, and
exposure/intervention, the results of these studies was also diverse. About half of
these studies showed that reminiscence therapy resulted in a statistically significant
decrease in depression. Despite that reminiscence therapy requires further testing, it
should be considered as a valuable intervention. Future directions of studies on
reminiscence therapy are suggested.

Urolithiasis is the process of forming stones in the kidney, bladder, and
urethra. The prevalence of urolithiasis is approximately 2 to 3 percent in the general
population. The development of the stones is related to decreased urine volume or
increased excretion of stone-forming components such as calcium, xanthine, oxalate,
cystine, urate and phosphate. Herbal plants have been the basis for medical treatments
since ancient time, and such traditional medicines still widely practiced today. The
scope of herbal medicine is sometimes extended to include fungal and bee products,
as well as minerals, shells and certain animal parts. In this study in vitro antiurolithiatic activity of Citrus limetta was done by two methods. Method A. was test
by turbidity method in which method activity of the extract was tested in terms of
inhibition of calcium oxalate formation by the method of Prachi Khare et al. with
modification and Method B.was test by calcium oxalate dissolution method in this
second method the role of plant extract in dissolving the already formed calcium
oxalate stones nucleus in artificial system. The experiment was carried out in four
arrangements according to the method of Unnati Atodariya et al. with modification.
In the method A it was observed that the extract with 100 mg/ml concentration has
shown higher percentage of inhibition (35.29%) of calcium oxalate formation than
the extract with 250 mg/ml concentration. While the standard drug has shown
percentage inhibition of 58.82% and in Method B the Low Dose of the Extract (50
mg/ml) had shown 15.2% of dissolution and High Dose of the Extract (100 mg/ml)
had shown 27.7%, while the standard cystone (50 mg/ml) had shown 68% of
dissolution of calcium oxalate. From the study it can be concluded that the
hydroethanolic extract of Citrus limetta possesses in-vitro anti urolithiatic activity
which can be due to the presence of phyto-constituent such as flavonoids present in it.

duration. In group EI, the testicular tissue was exposed to 100µg/ml and 200µg/ml of
permethrin. EII group was exposed to 100µg/ml and 200µg/ml of permethrin along
with 0.1mmol of vitamin C. While EIII group was tested for 100µg/ml and 200µg/ml
of permethrin along with 100µg/ml hydro-alcoholic extract of TT. Present study
revealed that the activity of antioxidant markers such as catalase (CAT), glutathione
peroxidase (GPx) and reduced glutathione (GSH) were significantly (p<0.05)
decreased in permethrin treated groups as compared to control in both dose and time
dependent manner. Maximum decline (62.69%, 39.4%, 51.5% decrease in level of
CAT, GPx, GSH respectively) in the antioxidant status of the tissue was reported at
200µg/ml for the duration of 8hr. However, 100µg/ml of permethrin resulted in
29.3%, 14.3%, 29.5% decrease in CAT, GPx, and GSH level respectively for the
same exposure duration i.e. 8hr. The activity of antioxidants was found to be
improved in vitamin C (EII) and TT (EIII) supplemented groups (p<0.05). From the
present study, it is concluded that permethrin induce a decline in the status of
antioxidant enzymes. Vitamin C and TT are potent antioxidants that mitigate the
toxic effects of permethrin by elevating the level of antioxidants.

Wide range of inter-annual climatic variability and frequent occurrence of
extreme climatic events is a great concern. There is a need to assess the impact of
such events on agriculture and to suggest suitable agri-management options for
sustenance. The appropriate regional based agro-advisory needs to be established for
the farmers and other stake holders. Inter-annual climatic variability has to be linked
through growth and yield of crops and cropping systems in various production
environments of Bangladesh. Climate change is a global concern, and we must
identify vulnerable regions as well as identify suitable mitigation and adaptation
strategies through various agronomic and management options to sustain the
agricultural production. Development of climate resilient agriculture is of paramount
importance. Agri-response must be evaluated in relation to future climate change
scenarios, in which crop modelling can play an effective role. With the help of crop
simulation tools, assessment can be made for newer production centres and
identifying suitable resource management options for maximizing production. Impact
of climate change needs to be worked out on regional scales by integrating crop
models with relational layers of bio-physical and socio-economic aspects. For this
purpose use of geographic information system (GIS) and remote sensing tools is
needed. In this review article, we have discussed about the inter-annual climatic
variability and occurrence of extreme climatic events in Bangladesh and their
association with agricultural production system. In this paper, we have demonstrated
the potential of crop models viz. INFOCROP, DSSAT to assess the impact of this
climatic variability and its change on growth and yield of crops and cropping systems
and thereby suggesting appropriate management options for sustenance.
