Toxic Effect Of Lead Chloride On Antioxidant Enzyme In The Liver And Kidney Of Fish, Bakhtawar Raza, Muhammad Javed, Faiza Ambreen, Fariha Latif Nov 2016

Toxic Effect Of Lead Chloride On Antioxidant Enzyme In The Liver And Kidney Of Fish, Bakhtawar Raza, Muhammad Javed, Faiza Ambreen, Fariha Latif

Journal of Bioresource Management

The contamination of aquatic habitats has become a serious problem for sustainability of the fisheries sector in Pakistan. Among different pollutants, heavy metals are very toxic. Their toxicity can be assessed by using antioxidant enzymes as biomarkers. These enzymes protect the living organisms from the oxidative stress caused by the heavy metals. Therefore, the effect of lead chloride (PbCl2) on the peroxidase enzyme activity in the tissues (liver and kidney) of Cirrhinamrigala was investigated. Four groups of Cirrhinamrigala were exposed, separately, to 96-hr LC50 concentration of PbCl2 along with its sub-lethal concentrations, viz.2/3rd, 1/4th and 1/5th for a period of …

Characterization And Analysis Of Pcs1 Gene From Wheat, Haris Ahmed Khan, Ayaz Ahmad, Sehar Nawaz Nov 2016

Characterization And Analysis Of Pcs1 Gene From Wheat, Haris Ahmed Khan, Ayaz Ahmad, Sehar Nawaz

Journal of Bioresource Management

Wheat (Triticum aestivum) is an important cereal crop grown worldwide on large areas. Yields of wheat are decreasing worldwide due to heavy metal contamination. A number of genes have been characterized as those that confer tolerance to cadmium stress. PCS1 is one of them. Phytochelatins have a key role in the detoxification of heavy metals in plants. However, the mechanism behind the detoxification remains unknown and wheat genes related to detoxification have not yet been identified. Here we report the isolation of cDNA encoding of phytochelatin synthase (PCS) from wheat (var. Galaxy 2013). The AtPCS1 cDNA sequence contained …

Black-Legged Kittiwake (Rissa Tridactyla) In Karakoram: Record On Vagrancy, Fakhar -I- Abbas, Madeeha Manzoor, Imran Shah, Afsar Mian Nov 2016

Black-Legged Kittiwake (Rissa Tridactyla) In Karakoram: Record On Vagrancy, Fakhar -I- Abbas, Madeeha Manzoor, Imran Shah, Afsar Mian

Journal of Bioresource Management

A Black-legged Kittiwake (Rissa tridactyla; BLK) circumpolar shore bird was recorded on the Borith Lake (36°25'54.31"N, 74°51'44.09"E) 4,000-5,000 km away from the gull family bird's eastern or western normal habitat and 2000 km from its last report few years ago and 1500 km from nearest seashore. This report discusses the possible reasons and so far reported vagrancy of this bird.

Effect Of Manganese Chloride (Mncl2) On Peroxidase Activity In Labeo Rohita, Nadia Altaf, Muhammad Javed, Sidra Abbas Nov 2016

Effect Of Manganese Chloride (Mncl2) On Peroxidase Activity In Labeo Rohita, Nadia Altaf, Muhammad Javed, Sidra Abbas

Journal of Bioresource Management

Four groups (n=10) of one year old Labeo rohita were exposed to 96-hr LC50 and sub-lethal (2/3rd, 1/4th and 1/5th) concentrations of MnCl2 for a duration of 30 days in the glass aquaria of 50L water capacity. After an exposure period of 30 days, the activity of peroxidase enzyme in the liver and brain of MnCl2 exposed fish was measured and compared with the control group. Physico-chemical parameters of the test media, viz. pH, dissolved oxygen, carbon dioxide, total ammonia, total hardness, calcium and magnesium were also monitored on a 12 hour basis during the whole experimental duration by following …

An Investigation Of The Major Wheat Weeds In Different Zones Of Dera Ismail Khan, Zahid Usman, Ejaz Ahmad Khan, Iqtidar Hussain, Anis Ali Shah, Kalim Ullah, Muhammad Sadiq Jul 2016

An Investigation Of The Major Wheat Weeds In Different Zones Of Dera Ismail Khan, Zahid Usman, Ejaz Ahmad Khan, Iqtidar Hussain, Anis Ali Shah, Kalim Ullah, Muhammad Sadiq

Journal of Bioresource Management

On account of huge yield losses, weed infestation is a serious threat in wheat crops throughout the country. A comprehensive survey to find out the major weeds in wheat in Dera Ismail Khan was carried out during the crop season of 2012-13. Wheat fields at seed farms of Rakhmanghan, RakhZandani, Rata Kulachi and adjacent farmer’s fields to each seed farm were investigated. Data was collected at the peak growth stage of weeds and the quadratic method was used to record relative density (RD), relative frequency (RF), relative crowding coefficient (RCC) and importance value index (IVI). The results revealed that the …

Metal Mixtures Toxicity And Bioaccumulation In Tilapia Nilotica At 96-Hr Lc50 Exposure, Faiza Ambreen, Muhammad Javed Jul 2016

Metal Mixtures Toxicity And Bioaccumulation In Tilapia Nilotica At 96-Hr Lc50 Exposure, Faiza Ambreen, Muhammad Javed

Journal of Bioresource Management

Laboratory tests were conducted on fingerlings of Tilapia nilotica to check the bioaccumulation patterns of lead (Pb), cadmium (Cd) and cobalt (Co) during acute toxicity at constant water temperature, pH and total hardness. Metal mixtures viz. Lead + Cadmium, Cobalt-Lead and Cadmium-Cobalt were selected to assess the acute toxicity in terms of 96-hr LC50 along with bioaccumulation patterns in selected organs of Tilapia nilotica (skin, muscles and liver). Sensitivity of Tilapia nilotica in terms of 96-hr LC50 for all mixtures varied significantly. The 96-hr LC50 of binary metal mixtures agreed in that order: cadmium-cobalt > lead-cadmium > cobalt-lead with statistically significant differences …

A Survey Of Weed Varieties In Samanabad, Lahore, Sadaf Nazir, Beenish Zia Butt, Anjum Navid Jul 2016

A Survey Of Weed Varieties In Samanabad, Lahore, Sadaf Nazir, Beenish Zia Butt, Anjum Navid

Journal of Bioresource Management

A weed is an herbaceous plant that grows as a wild plant, and is considered a hindrance in the growth of preferred vegetation or cumbering the ground, and has no value for beauty or use. However, some weeds have roles in medicine, ecology and many other fields. A survey was conducted in Lahore to observe the weed varieties present in the area of Samanabad. The present study was carried out in May and June 2014.The primary purpose of the study was to gain knowledge about the availability of the total number of species present in this area. We also assessed …
