Description of new nematode genus, Tetratobrilus dentatus gen nov. sp. nov. of Order- Triplonchida from West Bengal, India.

A new free-living nematode Tetratobrilus dentatus gen. nov. sp. nov. under family Tobrilidae Filipjev, 1918 of the order Triplonchida Cobb, 1919 is described from a drowned paddy field soil (mud) in West Bengal, India. It is characterized by heavily sclerotized walls of anterior portion of the buccal cavity, a small dorsal tooth and two sub-ventral...

A new species of free-living soil nematode, Terschellingia didistalamphida sp. nov., is described from paddy field in West Bengal, India. It is characterized by moderate body length (L=1.0-3.5 mm), possesses two amphids, only four cephalic setae. Amphideal fovea distant from the anterior end, stoma small and narrow, pharynx with well-developed term...

A huge plethora of dynamic microbial communities present in and on the human body have a significant impact both on local (as for the gut microbiota on energy metabolism and obesity) and on distant scales (as the association of the periodontal disease with coronary heart disease). This microbiota contributes significantly to the host biology includ...

Background: Trigonella foenum graecum (TG) Linn. (Methi) is widely used as a spice and known for its pharmacological properties. Objective: The current study was conducted to examine the efficacy of TG Linn., family: Fabaceae, against sodium arsenite-induced toxicity in mice. Materials and Methods: Sixty mice (Mus musculus) weighing about 25 g were...

A new predatory nematode species, Actus shamimi n. sp., is described and illustrated. Actus shamimi n. sp. is characterised by medium body length, buccal cavity barrel-shaped with apex of dorsal tooth located at ca 80% from base of cavity and 3-6 subventral denticles present in each latero-subventral row, cardia triangular in shape, amphidelphic go...

he species Prionchulus kralli Winiszewska et Susulovsky, 2004 is reported for the first time from India. To date, twenty-nine species of the genus Prionchulus have been described from various parts of the world, but only three have been described from India. Two females but no male specimens of P. kralli were found. They showed body of medium lengt...

Hyperthyroid patients develop left ventricular hypertrophy associated with alterations of several cardiac parameters such as heart rate, cardiac output, cardiac contraction and hemodynamic overload leading to cardiac complications. Although cardiac hypertrophy and contractile abnormality occur, interstitial fibrosis in the heart usually does not ta...

To understand the mechanism of cardiovascular dysfunction in the hyperthyroid condition, the role of oxidative stress was examined in rats treated with 3,5,3'-triiodo-l-thyronine (T3). Treatment of rats daily with T3 (8 microg/100 g BW) for 15 days resulted in an increase in heart weight to body weight ratio, which was ameliorated by antioxidants,...

Experiments were carried out to identify the altered genes in hyperthyroid rat heart and their influence on the functions of cardiac myocytes. Chronic treatment of rats with 3,5,3' triiodo-L-thyronine (T3) resulted in a prominent increase in the size of the left ventricle with increased wall thickness and reduced chamber volume leading to concentri...

The antiulcer effect of melatonin on gastric lesions caused by piroxicam was studied with the intent of determining the mechanism of action of this agent. Melatonin dose-dependently lowered piroxicam and indomethacin-induced gastric damage with more than 90% inhibition at a dose of 60 mg/kg BW. Increased lipid peroxidation, augmented protein oxidat...

Heart disease is one of the major health problems of advanced as well as developing countries of the world. Extensive research through the last decade has shown beyond doubt that free radicals, particularly, reactive oxygen species play a cardinal role in the pathogenesis of oxidative myocardial damage with consequential cardiac malfunction. This r...
