Bone is a hard and resilient tissue structure that provides mechanical support for the body of an organism. This study was aimed to evaluate the radiographical and biochemical changes during postnatal bone development of forelimbs in Nigerian indigenous puppies from 2-week-old to 24-week-old. Six (6) Nigerian indigenous puppies were chemically restrained using chlorpromazine at 2 mg/kg I.M. and positioned using ropes and sandbags for mediolateral and craniocaudal views of bones of the forelimbs. At 2-week-old, radiographic evaluation of bones of the forelimbs were undertaken and continued bi-weekly up to 24-week-old. Serum samples were analysed from 4-week-old to 24-week-old at four weeks’ interval for mineral (electrolytes) using colometric method for calcium and phosphorus and flame photometry method for sodium and potassium. At 2-week-old, there was an ill-defined radiopaque secondary ossification centre at the proximal epiphysis and a small ovoid radiopaque structure at the distal epiphysis of the humerus. There was not any sign of secondary ossification centre at proximal and distal epiphyses of both radius and ulna. There was the presence of a small radiopaque (ill-defined) accessory carpal. 1st to 5th metacarpals were present together with the proximal, middle and distal phalanges of all digits except the 1st digit that has proximal and distal phalanges. From 20-week-old, fully developed carpals and bony structures were observed through 24-week-old where the commencement of fusion of apophyses of olecranon (proximal epiphysis of ulna) at the centre and acrophyses of metacarpals and phalanges. The mean values (mean ± SEM) from serum biochemistry of calcium, phosphate, sodium and potassium in mmol/L from this study were within the normal limits throughout the study. Conclusively, the complementary information from calcium, phosphate, sodium and potassium in this study showed that these elements are within the normal limit that suggests normal bone development during the study period, which stressed the importance of the knowledge on serial changes of bone development which could be useful in clinical practice.

Blood samples were collected from thirty, 2-year old female Arabian camels from the eastern region of Oman. Camels were managed in the traditional way in the Arabian Gulf region, primarily fed fresh alfalfa and barley grain. Blood was drawn into serum vaccutainers from jugular venipuncture. Serum samples were analyzed by spectrophotometric analysis using a CX7/CX7 serum chemistry analyzer (Synchron, Beckman). Means, standard deviations and minimum and maximum values were calculated using Excel spreadsheets on Microsoft Office 2007. The SAS (2000) package was used to produce coefficient of determination (R2) between the eight serum mineral values. The following mean values Å} standard deviation were recorded: glucose: 92.8Å}19.2 mg/dL; total protein (TP): 6.17 Å} 0.34 g/dL; albumin: 32.21 Å} 9.933 mg/dL; blood urea nitrogen (BUN): 15.48 Å} 4.49 mg/dL; creatinine: 1.64 Å} 0.238 mg/dL; uric acid: 0.28 Å} 0.041 mg/dL; total globulins (TG): 0.28 Å} 0.041 mg/dL; cholesterol: 40.52 Å} 13.225 mg/dL; total bilirubin: 0.34Å}0.124 mg/dL; alkaline phosphatase (ALP): 113.9Å}29.75 (IU/L); aspartate aminotransferase (AST): 88.8Å}70.03 (IU/L); alanine aminotransferase (ALT): 13.3Å}5.97 (IU/L); Gamma-Glutamyl Transpeptidase (GGT): 21.3Å}10.18 (IU/L); lactate dehydrogenase (LD); 419.9Å}160.38 (IU/L); Creatine kinase (CK): 46.3Å}16.2 (IU/L); sodium (Na): 144.5Å}5.80 mmol/L; potassium (K): 4.23Å}0.42 mmol/L; calcium (Ca): 9.63Å}0.43; phosphorus (P): 9.56?Å}0.76 mg/dL; iron (Fe): 107.8Å}25.54 μg/dl; copper (Cu): 72.5Å}8.08 μg/dl; chlorine (Cl): 113.0Å}4.52 mmol/L. Findings of the current study provide baseline values that may be used by clinicians for racing camels in Oman. There were some significant correlations especially between macro minerals (Na, Ca, K, and P) that may be used to estimate their values with less cost by reducing the number of elements to be analyzed.

Abstract We study size-at-age and sexual variability of morphometric characteristics of the marsh frog. According to the size of the body, males were divided into three size-age groups (juvenis, subadultus, adultus), females — into four groups (juvenis, subadultus, adultus, adultus-I). We found that the chronological age of frogs (skeletochronology) does not always correspond to their biological age (size and proportions of the body). We noted that the semi-adult males are reliably larger than females by mean values of 26 studied morphometric characters. Males and females of “adultus” group do not differ by linear body size, significant differences were found in body proportions (7 characters). For the females of “adultus-I” group, the mean values of 26 characters are significantly larger than for “adultus” males. The results of our study showed that with the age of the marsh frog, the level of exhibition, directionality and structure of morphometric sex differences changes.

Body Balance

Background: The aim of the study is to assess the body balance and podological parameters and body composition of young footballers in the context of the control of football training. Methods: The study examined the distribution of the pressure of the part of the foot on the ground, the arch of the foot, and the analysis of the body composition of the boys. The pressure center for both feet and the whole body was also examined. The study involved 90 youth footballers from Olsztyn and Barczewo in three age groups: 8–10 years, 11–13 years old, and 14–16 years. The study used the Inbody 270 body composition analyzer and the EPSR1, a mat that measures the pressure distribution of the feet on the ground. Results: The results showed statistically significant differences in almost every case for each area of the foot between the groups of the examined boys. The most significant differences were observed for the metatarsal area and the left heel. In the case of stabilization of the whole body, statistically significant differences were noted between all study groups. In the case of the body composition parameters, in the examined boys, a coherent direction of changes was noticed for most of them. The relationships and correlations between the examined parameters were also investigated. The significance level in the study was set at p < 0.05. Conclusions: Under the training rigor, a statistically significant increase in stability was observed with age. The total length of the longitudinal arch of both feet of the examined boys showed a tendency to flatten in direct proportion to the age of the examined boys. Mean values of the body composition parameters reflect changes with the ontogenetic development, basic somatic parameters (body height and weight) and training experience, and thus with the intensity and volume of training. This indicates a correct training process that does not interfere with the proper development of the body in terms of tissue and biochemical composition.

Rates of insorption of radiosodium and radiopotassium from the unobstructed small bowel of rats were determined and compared with those obtained by others in healthy humans. Insorption of the isotopes under study was estimated by integration of their rates of appearance in the blood after placement in the small bowel and their rates of disappearance from blood after injection into the circulation. The rates of disappearance from arterial blood were determined during separate tests. They followed an exponential pattern similar though not identical with that reported from other species by other investigators. Radiosodium was insorbed more rapidly than radiopotassium. Mean values indicated that 50% of administered radiosodium was insorbed within 6–7 min, whereas 26–27 min were required for insorption of 50% of the radiopotassium. The rate constant during insorption of the first 76% of the Na22 was 10.8% per min and that for insorption of 58% of the K42 was 2.7% per min.

Uncoated Steel

Artificial material such as stainless steel (SS) is widely used for orthopaedic applications owing to its superior properties, ease of fabrication and lower cost. However, in the body environment, stainless steel can leach toxic elements such as nickel and chromium. To prevent this, a hydroxyapatite (HAp) coating having chemical characteristics very similar to the human bone was deposited on a medical-grade UNS S31254 austenitic stainless steel by a Low-velocity oxy-fuel spray gun (LVOF). The coating was characterised by using a field emission scanning electron microscope (FESEM), X-ray diffractometer (XRD) and Fourier transform infrared spectroscope (FTIR). The adhesion strength, microhardness and corrosion behaviour were studied using the Tensometre, Vickers microhardness tester and potentiodynamic polarisation with electrochemical impedance spectroscope. The bacterial adhesion and bioactivity of the coating were also evaluated. The LVOF sprayed HAp coating has shown better corrosion resistance, higher bioactivity and higher hardness than the uncoated steel. The presence of tricalcium phosphate, octa-calcium phosphate (OCP) and tetra-calcium phosphate (TTCP) was found in the coating. LVOF sprayed HAp coating is also found suitable in lowering the bacterial adhesion on the steel substrate.

There are six electrolytes that are important in maintaining homeostasis within the body. They play vital roles in regulating neurological, myocardial, muscular and cellular functions and are involved in fluid and acid–base balance. Recognising and treating electrolyte derangements is an important role for veterinary nurses especially in emergency and critical care patients. This series of two articles will discuss the physiology behind each of the six major electrolytes and discuss to monitor and treat any abnormalities.

The results obtained in this investigation are admittedly not as extensive as is desirable but they allow certain conclusions to be drawn. 1. The sodium and potassium contents of the body fluid of Ascaris lumbricoides are somewhat variable, but these variations do not seem to be dependent upon those of the external medium. 2. The calcium and magnesium contents of the body fluid are relatively constant and are not affected by those of the external medium. 3. The chloride concentration of the body fluid is closely related to and always remains lower than that of the external medium. 4. As shown in Table 2, there is a large gap between the total concentrations of inorganic cations and anions in the intestinal fluid of the pig. Presumably a considerable proportion of the inorganic cations are combined with organic anions, at present undetermined. Exposing the worms to saline media composed of chloride caused a large rise in the internal chloride concentration. This may well be a limiting factor in the life of the animals in such media, and the next step forward would seem to be the fuller analysis of the environment to which they are normally exposed.

Determining gender is one of the most important procedure in forensics. Teeth are made of the most enduring mineralized tissues in the body, as such, they have an extraordinary resistance to putrefaction and the effects of external agents (physical, thermal, mechanical, chemical or biological) which makes them invaluable material for anthropological, genetic, odontologic and forensic examinations.i)To assess the degree of sexual dimorphism in maxillary canine using maxillary canine index, maxillary first molar and central incisor using mesiodistal (MD) and buccolingual/buccopalatal (BL) dimensions of the crown. ii) To determine the accuracy of maxillary canine index, first molar and central incisor dimensions (mesiodistal and buccolingual/buccopalatal) in determining sex.This study consisted of total 30 participants (males=15, females=15) of age group ranging from 20 to 35 yrs. Measurement of dimensions of selected teeth were performed on maxillary cast using digital Vernier caliper, resolution 0.01mm. Data thus obtained were analyzed statistically.The mean values of all the measurements in males were greater than females. There was statistical significant difference in mean value of bucco-lingual width of molar, mesiodistal width of canine (on left side, right side and average) and the inter-canine distance between males and females. The buccolingual width of molar showed the highest % of sexual dimorphism (5.33%) and the mesiodistal width of molar showed the least % of dimorphism (0.7%). Bucco-lingual width of molar posed the highest prediction accuracy for gender determination. We conclude that buccolingual width of maxillary first molar can be used to predict the gender when only teeth of maxillary arch are available for forensic examination.
