Not AvailableTwenty one adult guinea pigs (BW 583.4±10.1 g) were divided into3 groups of 7 animals each. Animals in group T1 were fed a control (basal) diet while arsenic (As) was added either as sodium arsenite or arsenic trioxide @ 50 mg As/kg in group T2 and T3, respectively. Experimental feeding was continued for 11 weeks including a four days digestion trial. Dry matter intake was lower (P<0.05) and apparent absorption of As was higher (P<0.05) in As exposed groups. Growth rate and feed conversion efficiency were lower (P<0.05) in the arsenic exposed groups irrespective of the As compound. These results indicated that both compounds of arsenic (sodium arsenite and arsenic trioxide) given @ 50 mg/kg diet reduced feed intake, nutrient utilization and growth performance in guinea pigs.Not Availabl

Papillary carcinoma in thyroglossal duct cyst: An unusual case

Thyroglossal duct cysts (TDC) are commonly encountered in ENT practice. They are treated by Sistrunk’s operation in which the cyst along with the entire tract and part of hyoid bone is excised to prevent any recurrence. Very rarely TDCs may harbour malignancy. In that situation the management protocol is different. We present the case of a 33-year-old female with the unexpected finding of a papillary carcinoma arising in a submental TDC and is described with special regard to the rarity of the localization and the different options in the management strategy when carcinoma is found incidentally following surgery

Post-Emergence Herbicides for Effective Weed Management, Enhanced Wheat Productivity, Profitability and Quality in North-Western Himalayas: A ‘Participatory-Mode’ Technology Development and Dissemination

‘Participatory-mode’ adaptive research was conducted in wheat in north-western Himalayas (NWH) during 2008–2014 to develop an improved chemical weed management (ICWM) technology. First of all, two years ‘on-farm experimentation’ was performed in a randomized block design at 10 locations in NWH using seven treatments (Clodinafop @ 60 g a.i./ha (Clod); Clod followed by 2,4-D (Na-salt) @ 1.0 kg a.i./ha (Clod-fb-D); Isoproturon 75 WP @ 1.0 kg a.i./ha (Iso); Iso + D; Sulfosulfuron 75% WG @ 25 g a.i./ha + Metsulfuron 5% WG @ 2 g a.i./ha (Sulf + Met); weed-free-check; and un-weeded-check). In this study, the post-emergence application of Sulf + Met reported the lowest weed-index and NPK depletion by weeds with higher weed control efficiency (86.4%), weed control index (81.1%) and herbicide efficiency index (2.62) over other herbicides. Sulf + Met exhibited significantly higher wheat productivity (3.57 t/ha), protein yield, net-returns and water-productivity, which was followed by Iso + D and Clod-fb-D, all of which remained statistically at par with each other. An impact assessment of intensive technology-transfer programme (2008–2014) revealed a higher technology adoption rate (71–98%) of ICWM leading to higher wheat productivity (~22%) and net income gains (2.8–26.4%) in NWH. Overall, Sulf + Met proved highly effective against mixed weed flora in wheat to boost wheat productivity, profitability, quality and water productivity in addition to a higher technology adoption rate and NIGs to transform rural livelihoods in NWH
