New distribution records for Canadian Aleocharinae (Coleoptera, Staphylinidae), and new synonymies for Trichiusa.

Fifty-four new Canadian provincial records of aleocharine beetles (Staphylinidae), including three new Canadian records and one new North American record, are presented. Of these, 33 are new provincial records for Saskatchewan, 14 for Alberta, two for British Columbia, three for Manitoba, two for the Northwest Territories and one for the Yukon Territory. The following are new Canadian records: Trichiusapilosa Casey [formerly reported from Nova Scotia and Ontario as Trichiusapostica Casey], Acrotonarecondita (Erichson) and the adventive Palaearctic Athetanigra (Kraatz), which is also a new North American record.

Effect of radio-thyroidectomy and thyroid hormone replacement therapy on cardiac protein kinase activity and ATP hydrolysis.

The regulatory effect of thyroid hormone on cardiac protein kinase activity and ATP hydrolysis was studied in developing rats. Experimental hypothyroidism induced by a single intraperitoneal injection of 200 muCi of 131I led to a significant impairment of body and heart growth and elevated the activity of membrane-bound protein kinase (measured in the absence of cyclic AMP). However, a slight (11%) but statistically non-significant decrease was observed in soluble protein kinase activity in hearts of hypothyroid rats.
