Living populations of a large freshwater bivalve. Parreysia rajahensis (Lea, 1841) were found for the first time in the river Subernarekha. This bivalve species was found to occur in six localities of that river in altitudes ranging from 11 m to 196 m above mean sea level. In the middle reach of the river at Moori, Lupungdih and Maubhandar only empty shells of this bivalve species were available. Whereas, living populations of this bivalve were observed in the lower reach of the river at Gopiballabhpur and Jaleshwar. In addition, one living specimen of P. rajahensis was found in Kharkai confluence at Domuhani. Water qualities of the sampling sites were measured and relative abundance of this bivalve species along with its associate benthic molluscs was also estimated.Keywords

Aim: The present study is a pilot study which was carried out to evaluate the prevalence of mucositis and its grading in head and neck cancer patients undergoing chemotherapy, radiation therapy or combination. Also it evaluated the prevalence of candida colonisation and its species in cancer patients as opposed to healthy individuals.
Methodology: The pilot study consisted of 35 patients divided into three groups, Group A consisting of 15 oral cancer patients divided into 3 groups of 5 each undergoing chemotherapy, radiation therapy or a combination respectively.Group B consisting of 5 oral cancer patients who did not receive any treatment till then. . Group C consisting of 15 healthy patients without any oral lesions. The patients were then assessed for the prevalence of oral mucositis and graded according to WHO criteria .A oral swab was taken from the labial and buccal vestibule of each of the 35 patients including the two control groups
Results: 100 percent patient receiving radiotherapy showed xerostomia and mucositis. Candidal carriage increased with the increase in xerostomia. Candida albicans was the species found in all the samples..
Conclusion: The study emphasizes the need to investigate and clarify the role of antifungal and antiviral prophylaxis in the severity of oral mucositis, pain and xerostomia in head and neck cancer patients who receive RT with or without chemotherapy.

A large magnitude (Mw 7.8) earthquake occurred on 25 April 2015 (06:11 UTC) at 28.1473°N and 84.7079°E, 34 km east-southeast of Lamjung, Nepal. The devastating event was accompanied by two large aftershocks of Mw 6.6 (on 25 April 2015, 06:45 UTC) and Mw 6.7 (on 26 April 2015 at 09:10 UTC). According to the USGS earthquake catalogue, 65 aftershocks were recorded within a period of three days from the main event; the strongest aftershock had occurred on 12 May 2015 at 07:05 UTC.References
