Physicochemical, thermal and pasting characteristics of gamma irradiated rice starches.

Starches isolated from two recently released rice cultivars (PR 121 and PR 116) grown in sub-tropical climates of Punjab, India were subjected to gamma irradiation at 0, 2, and 10 kGy doses using a Co(60) irradiator source. Physicochemical, thermal, pasting, and morphological properties were studied. Irradiation resulted in a significant decrease in apparent amylose content, swelling power and pasting properties.

Impact of pollution on the flesh of some fishes inhabiting river Satluj waters--a biochemical study.

The impact of grossly polluted waters of the Budha Nallah (BN) on the flesh quality of a few fish species inhabiting river Satluj following its confluence with the river has been studied. For flesh quality, levels of extractable proteins (EP), carbohydrate content and total lipid (TL) contents have been compared in Cirrhina mrigala, Cirrhina reba, Crossocheilus latius and Mystus cavasius collected from downstream (DS) region (selected at 40-42 km following confluence of BN with the river) and an upstream (US) region (selected at 8-10 km before the confluence of BN with the river) of river Satluj. The results have shown a significant decline in the EP content, carbohydrates and TL contents in the flesh of these fish species collected from DS region.

Sialo proteins and phosphatases in estrual cervical mucus of fertile and repeat breeder buffaloes (Bubalus bubalis ).

Concentrations of sialic acid and protein and activities of acid phosphatase (ACP) and alkaline phosphatase (AKP) were determined in estrual cervical mucus of fertile and repeat breeder buffaloes during late estrus. Significantly (P < 0.01) higher concentrations of sialic acid and ACP and AKP activities were observed in fertile buffaloes as compared with repeat breeder buffaloes.

Studies on serum progesterone levels in relation to occurrence of uterine torsion in buffaloes (Bubalus bubalis ).

Serum samples from 32 buffaloes suffering from uterine torsion at approximately the completion of the gestation period were analyzed for progesterone concentrations by radioimmunoassay. Fifteen buffaloes had progesterone concentrations of more than 1.0 ng/ml (1.
