PURPOSES (1) To compare the Lafayette Instruments (LI) skinfold caliper to the Lange (L) and Harpenden (H) calipers using a diverse subject population. (2) To determine the validity of the LI caliper in a subset of subjects by comparing body compositions from skinfold thicknesses to those measured by hydrostatic weighing (HW) and air displacement plethysmography (ADP). (3) To compare measuremen...

The roles of ossification events, bone stages and bone ages in the prediction of the timing of the pubertal growth spurt are examined using data from the Harpenden growth study. In general, predictions made more than two years in advance of the average age of peak height velocity (PHV) are of little clinical value. The timings of certain ossification events and of PHV are related but the practi...

A survey of joint mobility was conducted in 295 healthy children between the ages of 5 and 10 years who attended a London primary school. Estimates of the commonly used measurements, that is passive dorsiflexion of the wirsts and ankles, passive hypertension of the elbows and knee, were too insensitive to detect any age effect. However, a method of estimating extensibility of the 5th metacarpop...

This study was conducted to determine the anthropometric measurements and body composition of selected national athletes. A total of 84 male athletes from 10 different types of sports and 24 female athletes from 5 types of sports were studied. The height and body weight of subjects were measured using the SEGA weighing balance with height attachment. Skinfold thickness measurements were taken u...

Secular trends of adiposity and motor development in preschool children since the fifties of the last century up to the beginning of this millennium were analyzed so as to reveal possible changes due to continuously differentiating lifestyle. In preschool children (n = 3678) height, weight, skinfold thickness over triceps, subscapular, and suprailiac were measured by Harpenden caliper in 1957, ...

Polystyrene mounting medium obtainable Ltd, 20 Du The medium described by Kirkpatrick One pounc and Lendrum (1939) and named by them mountant DPX (Distrene plasticised in xylene) was (75°% one replaced by a better formula in 1941. This medium BPS (butyl phthalate plasticised styrene) has given excellent and economical service until recently. The current trouble was not due to the makers of the ...

It is shown here that a suitable form for estimation and inference using the Michaelis-Menten [(1913) Biochem Z. 49, 333-369] model for simple enzymic reactions is one in which the two parameters appear in the denominator of the equation. In this form, convergence to the least-squares estimates using the Gauss-Newton method [see Kennedy & Gentle (1980) Statistical Computing, Marcel Dekker, New ...

BACKGROUND Postoperative irrigation after endoscopic sinus surgery and endoscopic modified Lothrop procedure is used to remove nasal crusts and to improve wound healing. To evaluate the optimal application protocol for irrigation of the frontal sinus, a prospective cadaver study was performed. METHODS An endoscopic modified Lothrop procedure and complete sphenoethmoidectomy were performed in ...

OBJECTIVE To compare three different body fats estimation equations using skin fold measurements with bioelectrical impedance analysis. METHODS A total of 130 subjects were included from Department of Endocrinology and Metabolism, Services Hospital, Lahore from 1st April 2016 to 30th Sep. 2016. The triceps, biceps, subscapular, chest, thigh, abdominal, suprailiac skinfold thickness of the sub...

Insects migrating over two sites in southern UK (Malvern in Worcestershire, and Harpenden in Hertfordshire) have been monitored continuously with nutating vertical-looking radars (VLRs) equipped with powerful control and analysis software. These observations make possible, for the first time, a systematic investigation of the vertical distribution of insect aerial density in the atmosphere, ove...
