Research Output | Dar Al-hikmah Library | IIUM Only

Now-a-days, bioaccumulation of toxic metals in aquatic animals causes serious threats to the human health when they are consumed. Thus the detection of toxic elemental concentration in aquatic flora and fauna has attracted various researches to determine their toxic levels in organism’s edible parts. Upon considering this issue, the accumulation

Spatial Concentrations of Lead and Copper in Bottom Sediments of Langkawi Coastal Area, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

Surface sediment samples were collected from 5 different zones of the Langkawi coastal waters, Malaysia to determine the concentration of Lead (Pb) and Copper (Cu) by using the sensitive Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The concentration of heavy metals was compared with the world average concentration of shale values. It was

Research Output | Dar Al-hikmah Library | IIUM Only

An effort to assess the utility of 650 bp Cytochrome C oxidase subunit I (DNA barcode) gene in delineating the members horseshoe crabs (Family: xiphosura) with closely related sister taxa was made. A total of 33 sequences were extracted from National Center for Biotechnological Information (NCBI) which include horseshoe crabs (Class: Merostomata),

Bioaccumulation of Heavy Metals in Horseshoe Crabs (Tachypleus Gigas) from Pekan, Pahang, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

An attempt was made to determine the various heavy metal accumulative concentrations in different body parts of horseshoe crab [Tachypleus gigas (Muller, 1785)]. Heavy metal accumulation levels were determined using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Highest mean concentration (μg g-1 wet weight) of iron (Fe), Zinc (Zn), Copper

Determination of Estuarine Sedimentation Rates Using 230thexcess and 230thexcess/232th Ratio Methods in the Paka Estuary, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

The vertical profiles of 230Thexcess and 230Thexcess/232Th in a sediment core have been used to determine the sedimentation rates of Terengganu River estuary, Malaysia. Applying the 230Thexcess and 230Thexcess/232Th method, U and Th isotopic involved complete dissolution of the samples, followed by separation on anion exchange, average sedimentatio

length-Weight Relationships of Seven Catfish Species in Peninsular Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

The study described the Length-Weight Relationship (LWR) of commercially important and indigenous freshwater catfishes from Peninsular Malaysia. Seven species of freshwater catfishes from three families (Bagriidae, Clariidae and Pangasidae) were collected from various rivers in Peninsular Malaysia. Allometric coefficient, b in LWR varied between 2.

Comprehensive Extraction Method Integrated with Nmr Metabolomics : a New Bioactivity Screening Method for Plants, Adenosine A1 Receptor Binding Compounds in Orthosiphon Stamineus Benth
Research Output | Dar Al-hikmah Library | IIUM Only

A large number of plant metabolites has provided as an incomparable chemical source for drug development. However, the wide range of the polarity of metabolites has been a big obstacle for full use of the chemical diversity. The initial step conventional extraction method by a single solvent does not make use of all the metabolites contained in pla
