Pangasius micronemus (Black Pangasius sp.) and Pangasius nasutus (Fruit Pangasius sp.) are two species of silver catfish widely consumed in Malaysia. The present study evaluated fatty acid profiles of fish muscles in these two Pangasius sp. from different farms and locations to determine which species or location is better in term of lipid quality. The results showed MUFAs (Monounsaturated fatty acid) content was highest (35.0-44.4%) followed by SFA (Saturated fatty acid) [32.0-41.5%] and PUFAs (polyunsaturated fatty acids) [9.3-19.3%]. P. micronemus of Sg. Kanchong displayed higher palmitic acid (SFA; 29.0%) than P. nasutus from Peramu (23.5%). In contrast, oleic acid (MUFA) revealed highest in P. nasutus (38.1%) while lowest in P. micronemus of Sg. Kanchong (29.7%). Additionally, utmost PUFAs belonged to P. micronemus of Sg. Kanchong (19.3%) and lower most in P. nasutus from Peramu (9.3%). P. micronemus presented with a higher EPA (eicosapentaenoic acid) [1.0-1.4%], DHA (Docosahexaenoic acid) [1.7-2.8%] and LA (Linoleic acid) [11.8-12.0%] than P. nasutus (EPA; 0.3%, DHA; 1.0%, LA; 4.8%). However, P. nasutus established higher GLA (gamma-linolenic acid) [0.4%] than P. micronemus (0.04-0.06%). Both Pangasius sp. can be regarded as good supplies of omega-3 and omega-6. Overall, P. micronemus from Sg. Kanchong is the best choice among all for reason high in EPA and DHA.

OBJECTIVE: To evaluate the aphrodisiac property of Aplysia dactylomela (A. dactylomelan), locally known as 'dugu-dugu', which is one of the sea slug species.
METHODS: Two types of extractions were used; aqueous and lipid. Three doses of each A. dactylomelan extract, respectively; 50, 100, 200 mg/kg were administered (i.p.) to male mice for mounting behavior test. Sildenafil citrate or Viagra® (5 mg/kg) being positive control while negative control received saline solution.
RESULTS: The animals treated with lipid extract at the respective dose exhibited mounting behavior, but the mounting frequency decreased at higher doses (100 and 200 mg/kg). However, all doses of aqueous extract did not show any mounting behavior. Meanwhile, in all doses of lipid extracts administered displayed significant difference (P<0.05) from the positive control. Despite this, only the lipid extract of 50 mg/kg showed significant difference (P<0.05) with negative control. This signifies that lipid extracts especially in dose 50 mg/kg have a substantial effect of aphrodisiac property. In addition, the presence of steroids was detected in the phytochemical screening of lipid extract.
CONLUSIONS: The findings from this study provides preliminary scientific evidence that A. dactylomela could be used as an alternative medication of natural product for promoting sexual activity in men.

Sea cucumbers are marine invertebrates of the phylum of Echinodermata that have been used in Asian traditional medicine since ancient times. This study was conducted to investigate the antioxidant and cytotoxic properties of aqueous and organic extracts from two sea cucumber species, Holothuria edulis Lesson (Holothuriidae) and Stichopus horrens Selenka (Stichopodidae). Antioxidant activities of the extracts were evaluated by DPPH· and β-carotene bleaching assays, while MTT and trypan blue exclusion assays were used to demonstrate the cytotoxic effects of the extracts against two human cancer cell lines, non-small cell lung cancer cells (A549) and esophageal cancer cells (TE1). The results showed that both aqueous and organic extracts of H. edulis were able to scavenge DPH radical (IC50 at 2.04 mg/ml and 8.73 mg/ml, respectively). Aqueous and organic extracts of S. horrens inhibited 79.62% and 46.66% of β-carotene oxidation by linoleate free radical. On the other hand, the organic extract of S. horrens exhibited the highest cytotoxic effects against A549 and TE1 cancer cells giving IC50 at 15.5 and 4.0 μg/ml, respectively. In conclusion, the present study revealed that H. edulis and S. horrens contain promising levels of antioxidant and cytotoxic natural products that might be used for cancer prevention and treatment.
