The Relationship

INTRODUCTIONA considerable amount of data now exists on the relationship between metabolism and body size in a wide range of organisms from bacteria and protozoans through to large mammals. Much of this information has been reviewed by Kleiber (1932, 1947), Brody and Procter (1932), Brody (1945), Zeuthen (1947, 1953), Hemmingsen (1950, i960) and Bertalanffy (1957). In general the metabolism has been shown to be proportional to a fractional power of the body weight thus eggs, the larger metazoan poikilotherms and even homoiotherms is proportional to a constant power of the body weight. This factor has been shown to be 0.751 ± 0.015 by Hemmingsen (i960). Superimposed upon this general relationship are variations according to the weight range of the organisms concerned. Thus both Zeuthen (1953) and Hemmingsen (i960) have shown that the value of the constant b for unicellular organisms is approximately 0.7 (Zeuthen, 1953) or 0.751 (Hemmingsen, 1960), whilst that for small metazoans is 0.95 (Zeuthen, 1953) or 1.0 (Hemmingsen, 1960). Finally, the slope of the line relating the metabolism to body size in larger metazoans is 075 (Zeuthen, 1953) or 0.751 (Hemmingsen, 1960). That is, the value for b — 1 in equation (2) is likely to be between -0.3 and -0.249 in unicellular organisms; 0 and -0.05 in small metazoans and approximately -0.249 in larger metazoans.Despite this apparently fundamental relationship between metabolism and body size, there are many instances where for a particular species the relationship may not apply. Indeed in some species the metabolism may vary in its relationship to body weight according to conditions such as salinity, shore level, experimental temperature and acclimation temperature.

The metabolic rate characteristics of six races of Peromyscus, selected from a wide range of habitats, have been determined over the temperature range 0° to 35 °C. After acclimation to standardized laboratory conditions, critical temperatures and metabolic responses to temperatures below thermoneutrality were largely a function of body size: the larger the mouse, the greater its thermoregulatory efficiency. Body size per se is not correlated with the gross climate of the respective habitats. A single equation which predicts the metabolic rate of these races at any temperature between 0° and 27 °C, from a knowledge of body weight and body temperature, is derived.When considered as a single group, the basal oxygen consumption of all races varied with body weight0,60 over the body weight range of 14.7 to 36.0 g and was insignificantly different from the accepted interspecies approximation. The basal metabolic rates of each race showed no temperature-adaptive differences, especially when considered in relation to body composition. It is concluded that basal metabolic rate is nonadaptive to climate in these races of Peromyscus and consequently has played no important part in their distribution and speciation.

ABSTRACTThis research on Morphometrics of Male Pasundan on Various Age was carried out in July 2018 in Cibalong District, South Garut Regency, West Java. This study aims to determine the relationship between body size of male calves at various ages and estimation of body weight using body size. The object in this study was 28 male calves at the age of 1-12 months. The results showed a relationship (R2 approaching 1) with the equation of each measurement, namely the Logarithmic regression equation for body lenght and chest deep (96,837ln(x) – 311,88), Polinomial regression equation for body and length body height (-0144x2 + 2,9524x – 48,433), Power regression equation for chest deep and chest girth (0,5317x0,9285), Logarithmic regression equation for body length and chest deep (34,974ln(x) – 110,5), Polynomial regression equation for body height and chest deep (0,004x2 - 0,1438x + 19,89). The result also show that the best model of estimating the body weight of Pasundan cattel is to use the the Polynomial formula with the equation y= 0.218x2 – 2.2536x + 76.074 where x is the size of the calf’s chest girth.Keyword: Extensive, morphometrics, pasundan male calf, weight estimation, polynomial

The purpose of the work is to determine and analyze the peculiarities of correlations between the constitutional parameters of the body and personality indicators of practically healthy Ukrainian women of the first mature age. Primary anthropo-somatotypological (anthropometric examination according to the scheme of V. V. Bunak, determination of somatotype – according to the mathematical scheme of J. Carter and B. Heath; determination of fat, bone and muscle components of body weight – according to the formulas of J. Matiegka, determination of muscular components of body weight – according to the method of the American Institute of Nutrition) and indicators of personality (leading typological characteristics of temperament according to Eysenck, psychodynamic features of personality according to Spielberger, indicators of severity and features of accentuated personality traits according to Shmishek, indicators of subjective control according to Rotter) of 101 practically healthy Ukrainian women of the first mature age were selected from the data bank of materials of the research center of National Pirogov Memorial Medical University, Vinnytsya. The analysis of correlations between anthropo-somatotypological indicators and indicators of personality traits was performed in the licensed package "Statistica 6.1" using the statistical method of Pearson. Between anthropo-somatotypological indicators and indicators of personality traits of practically healthy Ukrainian women, mostly single weak-strength feedback and direct reliable correlations have been established. In most cases, the feedback is established with the leading typological characteristics of temperament according to Eysenck, psychodynamic features of personality according to Spielberger and indicators of severity and features of accentuated personality traits according to Shmishek, and direct – with indicators of subjective control according to Rotter. The multiple nature of the relationship only between the rate of accentuation of the character of the exalted type according to Shmishek with most indicators of the width of the distal epiphyses of the limbs and the size of the pelvis; between the level of subjective control in the field of failures according to Rotter with half the longitudinal sizes of the body; between the indicator of situational (reactive) anxiety according to Spielberger, or the indicator of accentuation of the character of the cyclothymic type according to Shmishek with all the girths of the chest. Quantitative analysis of significant correlations between anthropo-somatotypological indicators and indicators of personality traits of practically healthy Ukrainian women revealed the largest relative percentage of reliable correlations of anthropo-somatotypological indicators. Namely, with the leading typological characteristics of temperament according to Eysenck, the largest relative percentage of reliable relationships was established with transverse body size and somatotypological indicators; with psychodynamic features of the personality according to Spielberger – with somatotypological indicators; with indicators of severity and features of accentuated personality traits according to Shmishek – with longitudinal body dimensions, cephalometric indicators and width of distal epiphyses of extremities; with indicators of the level of subjective control according to Rotter – with longitudinal body size and somatotypological indicators.

The buzz about hyaluronan (HA) is real. Whether found in face cream to increase water volume loss and viscoelasticity or injected into the knee to restore the properties of synovial fluid, the impact of HA can be recognized in many disciplines from dermatology to orthopedics. HA is the most abundant polysaccharide of the extracellular matrix of connective tissues. HA can impact cell behavior in specific ways by binding cellular HA receptors, which can influence signals that facilitate cell survival, proliferation, adhesion, as well as migration. Characteristics of HA, such as its abundance in a variety of tissues and its responsiveness to chemical, mechanical and hormonal modifications, has made HA an attractive molecule for a wide range of applications. Despite being discovered over 80 years ago, its properties within the world of fascia have only recently received attention. Our fascial system penetrates and envelopes all organs, muscles, bones and nerve fibers, providing the body with a functional structure and an environment that enables all bodily systems to operate in an integrated manner. Recognized interactions between cells and their HA-rich extracellular microenvironment support the importance of studying the relationship between HA and the body’s fascial system. From fasciacytes to chronic pain, this review aims to highlight the connections between HA and fascial health.

1. The O2 consumption and CO2 release of nine giant tortoises Testudo gigantea (weight range 118 g-35·5 kg) were measured at a temperature of about 25·5°C. Four European tortoises Testudo hermanni (weight range 640 g-2·16 kg) were also used. The mean RQ values obtained were 1·01 for T. gigantea and 0·97 for T. hermanni. These values were not influenced by activity or size. 2. The data was analysed by plotting log/log regression lines relating body weight to O2 consumption. Both maximum and minimum metabolic rates recorded for each individual T. gigantea showed a negative correlation with body weight. For active rates the relation was O2 consumption = 140·8W0·97, whereas for inactive animals O2 consumption = 45·47W0·82. 3. The maximum rates were obtained from animals that were observed to be active in the respirometer and the minimum rates from animals that remained quiet throughout. The scope for activity increased with body size, being 82 ml/kg/h for animals of 100 g and 103 ml/kg/h for 100 kg animals. The corresponding ratio between maximum and minimum rates increases from about 2 to 6 for the same weight range. 4. Values for metabolic rate in T. hermanni seem to be rather lower than in T. gigantea. Analysis of the relative proportion of the shell and other organs indicates that the shell forms about 31% of the body weight in adult T. hermanni but only about 18% in T. gigantea of similar size. The shell is not appreciably heavier in adult T. gigantea (about 20%). 5. Data obtained for inactive animals is in good agreement with results of other workers using lizards and snakes. Previous evidence suggesting that chelonians show no reduction in metabolic rate with increasing size is not considered to conflict with data obtained in the present work.

1. Thirty Suffolk × Half bred lambs were slaughtered at the following ages: two twin lambs at birth and two singles and two twins at 1, 2, 3, 4, 6, 8 and 16 weeks of age.2. The following weights were recorded: live-weight immediately before slaughter; and carcass, head, skin, feet, alimentary tract, heart, liver, kidneys, lungs and trachea, and blood immediately afterwards.3. The alimentary tract was emptied and weighed in four separate parts; reticulo-rumen, omasum-abomasum, small intestine, large intestine.4. The volumes of the reticulo-rumen and the omasum-abomasum were measured by immersing in water and filling the organs with water to 2 cm. pressure.5. The in vitro digestive efficiency of rumen liquor from lambs of 1, 2, 3 and 4 weeks of age was assessed.6. Empty body weight was considered to be valuable in comparing animals of different ages or from different feeding regimes or at different times of the year because variations in gut ‘fill’ were eliminated.7. There were no differences between singles and twins in the relationship of the fresh weights of the parts of the body to empty body weight, except that development of the liver and the blood was rather slower for singles.8. Little evidence was found of a difference in rate of development of the alimentary tract between singles an d twins, although the log an d square root transformation suggested a possible difference in reticulo-rumen size in favour of twins, significant at the 5% level.
