1. Plasma prorenin (inactive renin), which accounts for about 70% of the total renin in human plasma, was almost completely separated from active renin by affinity chromatography on Cibacron blue F3G-A-agarose. The slight residual renin activity present in the prorenin peak can be removed on concanavalin A-Sepharose, demonstrating that prorenin is completely inactive. 2. The renin activity of b...

Emotional stimuli often attract attention, but at what cost to the processing of other stimuli? Given the potential costs, to what degree can people override emotion-based attentional biases? In Experiment 1, participants searched for a single target within a rapid serial visual presentation of pictures; an irrelevant, emotionally negative or neutral picture preceded the target by either two or...

The transition from vegetative to reproductive development establishes new growth patterns required for flowering. This switch is controlled by environmental and/or intrinsic developmental cues that converge at the shoot apical meristem (SAM). During this developmental transition, floral inductive signals cause the vegetative meristem to undergo morphological changes that are essential for flow...

A longitudinal prospective surveillance for acute adenolymphagitis (ADL) was carried out in three villages in Rufiji district. A sample population of 3000 individuals aged 10 years and above was monitored fortnightly for a period of 12 months. The annual incidence of ADL was found to be 33 per 1000 population and was significantly higher in males than females (52.7/1000 and 18.7/1000 respective...

Approaches to the post-retirement phase of life have undergone considerable change during the last decades. Until the 1970s most people worked until age 65; early exit was due to physical or mental impairment. Retirement marked the beginning of old age, a stage of life characterized by disengagement and loss (Covey, 1988) and by a role-less state (Burgess, 1960). Older persons needed to accept ...

The diagnosis of severe retardation offers little difficulty. The behavior of the infant in the office and the developmental history will establish the diagnosis. The imbecile and idiot (I.Q. below 50) are unable to do what the average child half their age can do. It takes them 2, 3, 4, or more years to learn what the normal infant learns in 1 year. Motor development is retarded and efforts at ...

In this experiment 180 Azerbaijan province native laying hens from 28 to 40 weeks were separated in 6 treatments and 3 replicates (10 birds per replicate) as a (2 × 3) factorial arrangement of treatments in a completely randomized design. Treatments included two levels of dried tomato pomace (DTP) (8 and 16%) and 3 types of using methods (unprocessed, alkali and acid processed). The results sho...
