The objective of this work was to evaluate the morphometric and allometric relations of Iguaçu surubim (Steindachneridion melanodermatum) cultivated in net cages. One hundred and twenty specimens were cultivated at a density of 50 fish per square meter in three 6 m³ net cages. Fish were fed three times a day with commercial feed. Thirty fish were evaluated at 60, 120, 180, and 360 days of cultivation as to the variables: total body, head, clean trunk, viscera, skin, and fin weight; total, standard, and head length; and head and body height. The Iguaçu surubim shows later development of the clean trunk and early development of the other body parts.

Introduction: Body height is an important measure of physical identity. Height exhibits a dimensional relationship with various parts of the body. This relationship helps to calculate height from dismembered and mutilated body parts in forensic examinations. As the cranial dimensions are more reliable and precise means of predicting the stature, this study was undertaken to find the relation between head length and height and to derive a regression formula for the estimation of height from head length among dental students. Methods: This descriptive cross-sectional study was conducted among 150 dental students of age group 18-21 years in the Department of Anatomy, Kantipur Dental College Teaching Hospital and Research Center, Basundhara, Kathmandu. The head length was measured with the help of spreading caliper. Height was measured with the help of a standard height measuring instrument. The head length and the height of the students were measured in centimeters. Data obtained were analyzed to find the correlation between head length and height and to derive a regression equation for the estimation of height. Results: A significant positive correlation was observed between head length and height (r=0.734, P<0.001). The regression equation for body height and head length including both sexes and all age groups of dental students was found to be y=12.9+8.45x where x is head length and y is body height. Conclusions: It was observed in the present study that there was a significant positive correlation between height and head length in all the age groups indicating that head length is a reliable indicator in estimation of height.

Introduction: Estimation of stature for the purpose of identification has a significant forensic importance. This technique is based on a principle that bones or human body parts correlate positively with the stature. Stature can be estimated from measurements of various body parts such as arm, leg, feet, finger, facial height, nasal height etc. The aim of study was to correlate Stature of Nepalese with Nasal height and estimate Stature from Nasal height.Methods: A cross-sectional study of 214 healthy adults comprising 110 males and 104 females in the age group of 25 to 35 years were carried out. Study was carried out in central Nepal where people from various parts of Nepal are migrated. Total body height and Nasal height were recorded with stadiometer and sliding caliper respectively.Results: The mean of total body height in the male and female was 160.4 (±6.80) cm and 151.8 (±4.88) cm respectively. The mean of nasal height in the male and female was 4.6 (±0.31) cm and 4.3 (±0.29) cm respectively. This study observed that in both male and female nasal height had positive partial correlation with stature; r = 0.18 for male and 0.19 for female. Stature in nepali population could be calculated as: Stature=148.22+3.02x nasal height in male where as Stature=133.01+3.12x nasal height in female.Conclusions: Both Nepali male and female nasal height had positive partial correlation with stature; r = 0.18 for male and 0.19 for female. Stature in Nepali population could be calculated as: Stature=148.22+3.02x nasal height in male where as Stature=133.01+3.12x nasal height in female.Keywords: estimation; stature; nasal height. | PubMed

Abstract Erythroid progenitor cells in +/+ and Sl/Sld fetal livers manifested as burst-forming units-erythroid (BFU-E) and colony-forming units- erythroid (CFU-E) were assayed in vitro during early development. The proportion of BFU-E was higher as mutant than in normal fetal livers. On the other hand, the proportion of CFU-E was less in the mutant than in the normal. These results suggest that the defect in Sl/Sld fetal hepatic erythropoiesis is expressed at the steps of differentiation that effect the transition from BFU-E to CFU-E.

Allometric growth in larvae and juvenile blackhead seabream Acanthopagrus schlegelii (Bleeker, 1854) was studied. In the larval head, snout length, snout-gill slit distance, interocular distance and mouth width showed positive allometric growth, while eye diameter and head height showed negative allometric growth. In the head of juveniles, interocular distance and mouth width showed negative allometric growth, while all other organs showed positive allometric growth. In larval body, body thickness showed positive allometric growth, while all other body parts showed negative allometric growth. In the juvenile body, caudal peduncle length, caudal peduncle height and body thickness showed positive allometric growth, while head length, body height, trunk length and tail length showed negative allometric growth. All of the larval swimming structures (the dorsal fins, pectoral fins, pelvic fins, anal fins and caudal fins) showed positive allometric growth. The rapid development of key organs in the blackhead seabream after the initiation of exogenous nutrition allows for a significant increase in viability with minimal metabolic loss. The information generated through this study can provide a framework for understanding how blackhead seabream responds developmentally to challenging external pressures during their early life.

In leech embryos, segmental mesoderm and ectoderm arise from teloblasts by lineages that are already relatively well characterized. Here, we present data concerning the early divisions and the definitive fate maps of the micromeres, a group of 25 small cells that arise during the modified spiral cleavage in leech (Helobdella robusta) and contribute to most of the nonsegmental tissues of the adult. Three noteworthy results of this work are as follows. (1) The c′′′ and dm′ clones (3d and 3c in traditional nomenclature) give rise to a hitherto undescribed network of fibers that run from one end of the embryo to the other. (2) The clones of micromeres b′′ and b′′′ (2b and 3b in traditional nomenclature) die in normal development; the b′′ clone can be rescued to assume the normal c′′ fate if micromere c′′ or its clone are ablated in early development. (3) Two qualitative differences in micromere fates are seen between H. robusta (Sacramento) and another Helobdella sp. (Galt). First, in Helobdella sp. (Galt), the clone of micromere b′′ does not normally die, and contributes a subset of the cells arising exclusively from c′′ in H. robusta (Sacramento). Second, in Helobdella sp. (Galt), micromere c′′′ makes no definitive contribution, whereas micromere dm′ gives rise to cells equivalent to those arising from c′′′ and dm′ in H. robusta (Sacramento).

1. Throughout post-natal life the relative weights of the pituitary body, thyroid, thymus and adrenals in the rabbit may be expressed by the equation y = axk + c. 2. A similar association is indicated in the rat for the weights of eyeballs, liver, pancreas, hypophysis, thyroid, adrenals, submaxillary glands, kidney and fresh skeleton (data from Donaldson, 1924). 3. In giant and pigmy rabbits, the ultimate proportions of body parts are not the same, but (for any given body weight) corresponding tissues in the two groups tend to exhibit an identical relation to total body mass. 4. The adrenals and testes of the Polish rabbits are relatively much larger than those of the Flemish. But in each case the growth of the adrenal approximates to a constant power function of body weight. Moreover, in these two groups and in their hybrids, the growth of the testes adheres to a simple association with adrenal weight identical for each. 5. These data suggest the generalisation that in a growing organism the magnitude of any part tends to be a specific function of the total body mass or of some portion so related to the whole. 6. These associations may be explained by surmising that each tissue is in equilibrium with the internal milieu with regard to the distribution of nutrient growth essentials; that in each case the equilibrium point would be determined by the nature of the cell and after differentiation would tend to remain constant; and that the relative enlargement of each tissue is limited by the excess of the equilibrium value over the katabolic expenditure. 7. According to the above hypothesis of organ growth, the equation y = axk + c may possess a physical significance. Eight types of growth relationships may thus exist, differing because of the apparent inactivity of one or more constants in this equation.

The aim of the present study was to characterize the relationships that occur between morphometric variables of larvae of Lophiosilurus alexandri Steindachner, 1876 through their allometric growth analysis. Total length, head length and body height were correlated with standard length, head height and body height, as well as eye diameter and head height with head length. The results revealed allometric positive relation during the initial development, where the b coefficient varied between 1.10 and 2.81. The variable pre-anal distance in relation to the standard length and the snout length in relation to the head length revealed an allometric negative relation, where the b coefficient was 0.85 and 0.94, respectively.

Aquaculture is is often constrained by the availability of water, both in quality and quantity. The aim of this study was to determine the optimum maintenance system of elver (Anguilla bicolor bicolor) on a wet, moist and dry system through production performance studies and physiological responses. The research was conducted from August to September 2018 at the Production Technic and Management of Aquaculture Laboratory, Department of Aquaculture, IPB University. A completely randomized design with 5 treatments and 3 replications was used in this study, namely treatment with high water wet system 0% of body height (A), high water wet system 50% of body height (B), high water wet system 100% of body height (C), moist system (D), and dry system (E). The body weight of elver was 18.80 ± 0.62 g which derived from fish cultivator in Bogor, West Java. Fish was fed 3 times per day at satiation with commercial feed which a protein content of 50%. Results showed that treatment C was the best result with survival rate of 100%, the specific growth rate of 0.45% day -1, the absolute growth rate of 0.07 g day 1 and feed conversion ratio of 6.57. The analysis of variance showed that the treatments showed the significant effect (P <0.05). The blood glucose value closest to the eel condition before treatment was found in the treatment C.

This article presents the results of comparative research into the collocations of the names of human body parts with dimension adjectives. The aim of the analysis was to indicate the similarities, limitations and differences in the manners of conceptualising the world established in Polish and Korean, or more precisely: how both languages define the elements of the world of human body parts, and how they assign dimensions to the elements depending on the needs and experiences of native users of both. The results of the research could have a practical application in teaching both languages, facilitating students’ absorption of the lexis of the other language, and result in a deeper mutual understanding of linguistic and cultural differences..

Axolotls show a remarkable regeneration capacity compared with higher vertebrates, regenerating missing appendages such as limbs and tail as well as other body parts (i.e., apex of the heart, forebrain, and jaw) after amputations which makes this animal a very interesting research model for tissue regeneration mechanisms. Larvae are individually housed in a 20% Holtfreter’s solution within clear plastic containers. The photoperiod light : darkness cycle is 12 : 12 h. Larvae with a total body length of less than 5 cm are fed once a day with large brine shrimp and blood worm. Albino larvae appeared to have a tendency to exhibit abdominal distention. No clinical signs of illness seemed to be associated with the condition; however, these animals exhibit a relatively slower growth rate. To better characterize this condition, we performed histological sectioning for cross sectional slide preparation on wild type and albino axolotl larvae following euthanasia. The only lesion seen in the albino larvae was a thickened gut wall and the presence of fungi within the intestines. We hypothesize that this may be due to a lower efficacy of the albino larvae’s immune system.
