Taxonomic validation of five fish species of subfamily Barbinae from the Ganga river system of northern India using traditional and truss analyses.

Morphometric differences were investigated among five fish species of subfamily Barbinae from the Ganga river system through traditional morphometrics and the truss network system. Species taken into account were Puntius chola (Hamilton 1822), Puntius sophore (Hamilton 1822), Pethia ticto (Hamilton 1822), Pethia conchonius (Hamilton 1822) and Systomus sarana (Hamilton 1822). Although, taxonomists carefully examine external body features to discriminate these species, there is still a risk of misidentification during a visual assessment.

Phytochemicals in the treatment of ovarian cancer.

Ovarian cancer ranks 5 among the most common gynecologic cancers and causes the highest mortality in females. Here, we discuss the role of a group of natural products that are being used in treatment and prevention of a host of cancers including ovarian cancer. Some plants and nutraceuticals and their polyphenolic constituents such as flavones, flavonoids, and antioxidants have shown cytotoxic effects on cancer cells both and .

Oxidative Stress Biomarkers in the Freshwater Fish, Heteropneustes fossilis (Bloch) Exposed to Sodium Fluoride: Antioxidant Defense and Role of Ascorbic Acid.

The present study highlights fluoride -induced toxicity and the protective role of ascorbic acid in the liver and ovary of freshwater fish, Heteropneustis fossilis. The fish specimens were exposed to different concentrations (35 mg F/L and 70 mg F/L) of fluoride. Parameters related to oxidative stress were studied at the end of the experiment.

Effect of a non steroidal tamoxifen on the gonad and sex differentiation in Nile tilapia, Oreochromis niloticus.

The effect of different doses of anti-estrogenic chemical was studied in a cichlid Oreochromis niloticus on mortality, growth, sexual development and sex differentiation. Percent mortality (5, 10 and 10) appeared to be dose-dependent. All groups of tamoxifen (TA) treated fishes exhibited significant growth as compared to the controlled fishes.

Melatonin Induced Changes in Specific Growth Rate, Gonadal Maturity, Lipid and Protein Production in Nile Tilapia Oreochromis niloticus (Linnaeus 1758).

We have investigated the effect of melatonin (MLT) on specific growth rate (SGR% day(-1)), condition factor (k), gonado-somatic-index (GSI), histological structures of gonads, serum as well as gonadal protein and lipid in Nile tilapia Oreochromis niloticus. MLT treatment in the dose of 25 μg/L for three weeks reduced SGR% day(-1) (0.9±0.
