Modulation of the immune responses using active bio-ingredients as a possible prophylaxis measure has been novel prospect for aquaculture. The present study evaluated the effects of azadirachtin EC 25% on non-specific immune responses in goldfish Carassius auratus and resistance against pathogenic bacteria Aeromonas hydrophila. The experimental trial for(More)
Argulus are common aquatic ectoparasites that create one of the major threats to aquaculture due to absence of suitable therapy. Piperine, a bioactive component of Piper longum, has medicinal properties and acts as anti-inflammatory, antibacterial, and antifungal, considering eco-friendliness and cost-effectiveness. The present study aimed to evaluate(More)
Argulus is one of the most common and predominant ectoparasites which cause serious parasitic disease and is a potent carrier of viruses and bacteria in the ornamental fish industry. In recent years, organic (herbs)-based medicines are widely used to cure the disease, and neem (Sarbaroganibarini) medicine is very popular and effective throughout the world.(More)
Endosulfan is one of the most hazardous organochlorines pesticides responsible for environmental pollution, as it is very persistent and shows bio-magnification. This study evaluated the impact of acute endosulfan toxicity on metabolic enzymes, lysozyme activities, heat shock protein (Hsp) 70 expression, and histopathology in Tilapia (Oreochromis(More)
Four-month old adult siblings of zebrafish were exposed to four concentrations of diazinon for up to 168 h. DNA, RNA, protein and total free amino acid content were monitored in the liver. The DNA, RNA and protein contents were significantly reduced, whereas the amino acid content was significantly enhanced. All these changes showed dose- as well as(More)
Matrix metalloproteinases (MMPs) are reported to be involved in tumor growth, apoptosis, angiogenesis, invasion, and development of metastases. These are zinc containing metalloproteases, known for their role in extracellular matrix degradation. MMP-11 (stromelysin3) is reported to be highly expressed in breast cancer, therefore it may act as marker enzyme(More)
Anemia indicate poor health conditions usually associated with low economic status and poorly affecting both male and female. In females, the most common causes of anemia are malnutrition, menstrual cycle, and multiple pregnancies. It occurs due to insufficient consumption of dietary iron supplements or with increased utilization or loss of iron in body(More)
The present study evaluated the effect of dietary andrographolide (EC 50%) on growth, non-specific immune parameters and disease resistance against Aeromonas hydrophila infection in Indian major carp, Labeo rohita fingerlings. Fishes were fed with formulated diet containing andrographolide as T0 (0.00%), T1 (0.05%), T2 (0.10%), T3 (0.20%), T4 (0.40%) and T5(More)
The influx of pharmaceutical drugs and their metabolites have been reported to cause negative impact on aquatic biota. In this study, effects of long-term exposure of verapamil on mutagenic, hematological parameters and activities of the oxidative enzymes of Nile tilapia, Oreochromis niloticus were investigated for 60 days exposure at the concentrations of(More)
Steroidogenic acute regulatory protein (StAR) is responsible for the relocation of cholesterol across mitochondrial membrane in vertebrates and is, therefore, a key factor in regulating the rate and timing of steroidogenesis. In the present study, we developed chitosan nanoparticle (CNP) conjugated StAR gene construct (CNP-pcDNA4-StAR) in a eukaryotic(More)
