Accurate, consistent measurement of foot-ankle geometry is essential for the design and manufacture of well-fitting, functional, comfortable footwear; for the diagnosis of certain biomechanical disorders; and for consistent longitudinal monitoring and assessment of pedorthic treatment outcomes. We sought to formulate a basic set of measures characterizing the principal geometric dimensions of the foot, to investigate how these measures vary with increasing weightbearing, and to explore the implications of weightbearing changes in pedal geometry for orthopedic footwear design and manufacture. The right feet of 40 healthy men aged 22 to 71 years were scanned using the Department of Veterans Affairs Pedorthics Optical Digitizer in neutral alignment, sequentially bearing 0%, 10%, 25%, 50%, and 100% of the subjects’ body weight. With support of the full body weight, the following mean changes in the pedal parameters were observed: heel-to-toe length, 1.5%; ball width, 4.3%; maximum heel width, 4.8%; and instep height, –9.3%. On average, 71% of the changes sustained in the pedal parameters at full weightbearing occurred when, or before, 25% of the body weight was applied. (J Am Podiatr Med Assoc 96(4): 330–343, 2006)

Ayurveda is a ‘science of life” which provides not only curative but also preventive principles for healthy and long life. Ayurveda is a lifestyle; a science and art of appropriate living that ensures health and longevity of human being. Abhyanga which is one among the Dincharya, is also a part of therapeutic procedures of Panchakarma therapy. As it nourishes the senses of mind and gives the strength, but if done in the region like localized in head, neck, legs etc then it is termed as  Shiroabhyanga, padaabhyanga etc. Full body massage gives strength to whole body but localized massage gives strength to that particular part of the body. Localized massage can be practiced by self. Thus it is easy to practice. But for abhyanga one need to be dependent in massage trainer. The instructions to be followed under localized massage also. It gives its benefits when it is done in the right manner only.

The study was designed to determine the size of some body parts of the Super Kampong chicken and its relationship with body weight. The study was conducted at the Teaching Farm of Animal Science Faculty, University of Mataram, in Lingsar Village, West Lombok. The study used 60 male and 96 female Super Kampong chickens which were maintained intensively. The variables observed were body weight, head circumference, neck length, wing length, back length, chest circumference, chest width, upper and lower thigh length, metatarsus length, metatarsus circumference, and third finger length. Measurements were made for each individual bird at 13 weeks of age using yarn then measured with a tape measure, while the dimension of chest width was assigned  by measuring the distance between the right and right sides of the chest using calipers. The results found that the body parts that had the biggest contribution to the body weight of the Super Kampong chickens at 13 weeks old were the size of the lower thigh length in the male chicken and the size of the chest circumference in the female chicken.

Two sympatric smelt populations inhabit Lake Heney, Gatineau County, Quebec. This study deals only with the population which we call "giant" but a brief discussion on "small smelt — large smelt" theory is included. The data were obtained from 1556 specimens collected with eight gillnets set up under the ice at one locality on Lake Heney, in February, March, and April 1967. The data permitted the determination of the time and site of spawning in the giant population. The time and site of spawning in the "dwarf" population was already known, and we found a marked difference in the spawning behavior and time of spawning of the two populations. The two populations are furthermore reproductively isolated. The sex ratio during the spawning period was closely followed and found to be similar to that of all other freshwater or marine smelts. A DeGiusti dredge, dragged along the bottom below the position of the gillnets immediately after the melting of the ice, permitted the collection of embryonic smelt eggs from a depth of 30–40 ft.The maturity index, relative fecundity, and intergonadal ratio were especially studied. Ovary weight at maturity represents in average one-quarter the total body weight, and testis weight one-fortieth the body weight. A 213-mm female lays an average of 42,460 eggs. The right ovary is 4.5 times smaller than the left one, and the right testis is on the average 3.8 times smaller than the left one.There is a direct relationship between total fecundity and length of mature females. This relation is expressed by the curve log E = 4.54 log L + k.


Experiments had repeatedly been carried out on dogs to test the assumption that goitre could be conveyed from man to animals by fæcal infection of the water supply, but with negative results. In the present experiments female goats were employed. The drinking water supplied to these goats was fouled by passing through a specially constructed box, which contained sterilised soil mixed with the fæces of goitrous individuals. In the case of one batch six goats, only this water was consumed. In the case of another batch of seven goats the box above referred to contained, in addition to the sterilised soil and fæces, 500 earthworms. These were added on the assumption that they might act as intermediate hosts to the infecting agent of the disease. The goats consumed this highly polluted water for 64 days, from October 13 to December 15, 1910. The results observed were (1) a loss of weight, due doubtless to confinement in a small hut for the 64 days of the experiment; (2) that many of them suffered from diarrhœa; and (3) that 50 per cent. of the animals showed enlargements of the thyroid gland, most marked on the right side. The thyroids of three control goats showed no alteration in size. The enlargement of the thyroid was observed to fluctuate in size considerably, a fact which had previously been noted in the case of experimentally produced goitre in man. The average weight of the normal thyroid of the goat in Gilgit is 1/10,000 part of the body weight. The enlarged glands of the goats in the experiment were found to weigh from 1/4,272 to 1/7,000 part of the body weight. In both batches drinking fouled water the results observed were the same.

The present study was carried out to assess the contraceptive efficacy of sperm agglutinating factor (SAF) isolated from Serratia marcescens, in male Balb/c mice. Mice were administered via an intratesticular route with different concentrations of SAF, viz., 10, 50, 100, 200, or 400 µg, in the right testis only which served as a test while the left side served as control except otherwise stated. Mice were sacrificed on day 3, 7, 14, 21, 30, 45, 60, and 90 after administration, and results in terms of change in body weight, seminal parameters, tissue somatic indices (TSI), hematological parameters, serum level of testosterone, lipid peroxidation, and histology were studied. The body weight and TSI remained unaffected in all the experimental groups. In case of seminal parameters, the right testis treated with 10 μg, 50 μg, 100 μg, 200 μg, or 400 μg of SAF showed azoospermia up to day 7, 14, 21, 45, and 90, respectively. The hematological indices, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were found to be unaltered when the group receiving SAF (test) was compared with the groups receiving phosphate buffer saline (control) in the right testis; however, the treatment had a negative effect on the serum level of testosterone. It also affected the oxidative status of the right testis. Furthermore, histological studies revealed hypospermatogenesis and alterations in the seminiferous tubules which included intraepithelial vacuolation and exfoliation in the right side as compared to the left side. Thus, the results suggest that SAF (400 µg) causes suppression of spermatogenesis, without causing apparent toxic effects.

A study has been made of 521 bandicoots (Perameles nasuta, 324; P. gunnii, 111 ; Isoodon obesulus, 86). Near Sydney, P. nasuta breeds all the year round with no indication of any peaks of breeding activity. Limited observations on P. gunnii and I. obesulus in Tasmania also suggest that births occur in every season of the year. Parturition of a single individual of P. nasuta was witnessed. Fifteen new-born specimens of this species were measured and body weight records were obtained for five of them. The average dimensions of these specimens, and consecutive measurements of three specimens born in captivity and of known age, were used to age pouch young of unknown age. Age changes in the appearance of P. nasuta are described and illustrated. Hair emerges on the trunk at about 40 days after birth and at 2 months the coat is similar to that of the adult. The rate of body growth is extremely rapid just prior to the opening of the eyes (usually at 45-48 days), and the young first appear outside the pouch several days later. The pouch contains eight teats, and the mean litter sizes were: P. nasuta, 2.44 (52 litters); P. gunnii, 2.23 (22 litters); I. obesulus, 2.33 (9 litters). In 47 litters of P. nasuta, 73 young were on teats of the left side compared with 46 on the right side of the pouch. The sexes were equally represented in the pouch young of the three species examined. In P. nasuta, sexual maturity is reached at about 450 g in females and about 650 g in males. The linear equivalence (cube root of the body weight) is used as an overall measure of size with which the parts of the body are compared.

The purpose of this research project was to investigate whether or not clenching and occlusal instability of Angle’s Class I malocclusion have an effect on body weight distribution in healthy adult subjects. Twenty adults (fourteen males and six females, ages 27-40, mean age 31.7 years, SD 3.32) were included in this study. The MatScan (Tekscan Inc., Boston, MA) system was used to measure the body weight distribution changes of the subjects. Four body weight distribution measurements were taken for each subject while (1) the mandible was in the rest position (no tooth contact) (RES), (2) subject was clenching (maximum intercuspation of the teeth with heavy occlusal forces) (CL), (3) subject was clenching on the right side (with 1 mm disocclusion on the left side) (CLR), and (4) subject was clenching on the left side (with 1 mm disocclusion on the right side) (CLL). The lateral and the anteroposterior body weight distribution changes during the different clenching conditions (both sides, right, and left) were compared to those at which the mandible was at the rest position. The statistical significance of these results was tested with a Chi-Squared test (p<0.05). Based on the findings of the present study it was concluded that clenching and occlusal instability are associated with lateral body weight distribution changes.

SUMMARYSome aspects of sexual development and the attainment of puberty in Clun Forest ram lambs were studied during the two seasons 1970–1. Strong correlations existed between parameters of penial, scrotal and testicular development. Sexual development in general appeared to be more closely associated with the body growth than the chronological age of the ram lamb.Nevertheless, marked variation existed in both age and body weight at puberty. Although the majority of the lambs attained this stage of development at 4·5–5 months the age-range extended from 99 to 176 days. The mean body weight at puberty was 32·5 kg, ranging from 24·5 to 38·0 kg. There appeared to be an interaction between chronological age and general body development in relation to the appearance of sperm in the epididymides. Not only did it seem that a certain degree of body growth and testicular size was required before spermatozoa could be released, but also a limit of chronological age below which puberty was not attained. Large differences existed between individual lambs in both testicular and epididymal weights at puberty. There was a high degree of symmetry in growth between the left and the right testes and epididymides.Time of birth influenced the pattern and rate of body growth and sexual development. This seemed to be largely due to seasonal fluctuations in nutritional conditions during rearing but the results obtained do not preclude the possibility that other seasonal factors, such as the daylight environment experienced by the ram lamb, might have a certain limited influence on sexual development.

The article presents the results of assessing the informativeness of the improved technique of preoperative echocardiographic screening study in dwarf dog breeds. Evaluation of the ratio of the sizes of the left atrium to the root of the aorta, the pulmonary vein to the right branch of the pulmo-nary artery, normalized to the body weight of the end-systolic and end-diastolic dimensions, the fraction of the shortening of the left ventricle, the velocity of the peak E of the transmitral blood flow and the time of isovolumic relaxation makes it possible to carry out an effective preoperative assessment functional state of the cardiovascular system in dwarf dogs. These indicators do not de-pend on the body weight of dogs and characterize the state of remodeling, systolic and diastolic functions of the left chambers of the heart. Determination of the complex of these echocardiograph-ic parameters within 8-11 minutes makes it possible to assess the pumping function of the heart, to predict and reduce the risk of developing cardiogenic pulmonary edema.

The aim of this study was to analyze the effects of 12-week regular zumba exercises on antropometric properties. A total of 20 women who participated in the study were consisted of 10 for experimental group and 10 for control group with a mean age of 38.25 ± 4.22 who performed regular zumba exercise for 12 weeks. In the research, two measurements were taken as pre and post tests. In the study, body fat percentage measurements were taken by bioelectrical impedance analyses method and ciccumference measurements were taken by tape measure. The data obtained at the end of the research were evaluated in SPSS program. Arithmetic mean, standard deviation values of the measurements, intra and intergroup differences and percentage development differences were obtained. According to the findings of the research, a significant difference of p<0.001 value has been detected, as a result of the measurements taken for the body weight, BMI, BFB, waist, hip, abdomen, chest, lower chest, right leg, left leg, right calf, left calf, right arm and left arm measurements. With regard to the hip circumference, no significant difference has been detected between the groups. The change rates were observed within a 12-week period are as follows: 4,80% in the body weight, 4,87% in BMI, 5,75% in the BFP, 3,82% in the waist, 3,91% in the hip, 3,91% in the abdomen, 3,88% in the hip, 2,69% in the chest, 4,01% in the lower chest, 5,07% in the right leg, 4,76% in the left leg, 5,44% in the right calf, 5% in the left calf, 4,41% in the right arm and 3,78% in the left arm. A significant difference was found at the p <0.001 level in the first and last measurements of all variables of Zumba group. In conclusion, it can be said that 12-week regular Zumba exercises have effects on the reduction of Antropemetric properties. ​Extended English summary is in the end of Full Text PDF (TURKISH) file.   Özet Bu araştırma düzenli zumba egzersizlerinin antropometrik özellikler üzerine etkisini incelemek amacıyla yapılmıştır.  Araştırmaya 12 hafta düzenli zumba egzersizi yapan ve yaş ortalaması 38,25±4,22 olan 10 deney grubu ve 10 kontrol grubu olmak üzere toplam 20 kadın katılmıştır.
