SummaryThe breeding tract of Spiti horses is located in the Kaja subdivision of the Lahul and Spiti district and the Yanthang area of the Kinnaur district of Himachal Pradesh in India. The horses in this area are smaller in height and called Spiti ponies. They are reared as pack animals at high altitude. Their body is well developed with fairly strong bones. The mane is long and has hairs of 25 to 40 cm in length. The body is solid, displaying and alert attitude, the face is convex, the ears are erect and the eyes are black. The tail is medium in length and straight. The horses are docile in temperament. The body colours are grey, brown, black and piebald. On an average, these horses stand 129 cm height, have a body length of 100 cm, a heart girth of 148 cm, an ear length of 15 cm and a face length of 50 cm. Animals are reared on grazing (alpine pasture) from May to November and stall fed from December to April. The breeding season is from February to July. The average age at first fertile service, age at first foaling, gestation period, service period and foaling interval were estimated as 1 054, 1 297, 333, 63 and 516 days, respectively under intensive management at Kamand farm. It has also been ascertained from various sources that their number is declining rapidly, however breed population statistics are not available. There is, therefore, an urgent need to conserve this breed.

SUMMARYObservations were recorded on morphological characteristics, body weights and body measurements of 344 Malpura sheep belonging to nine age groups during a survey conducted in 18 randomly selected villages of three blocks of the Chittorgarh district of Rajastha. The body weights at birth, 1, 3, 6 and 9 months and adult weight averaged 3.3, 6.7±0.88, 12.9±0.71, 16.4±0.71, 21.0±1.00 and 31.4 kg respectively. Height, body length, chest girth, paunch girth, face length, face width, tail length and ear length of adult Malpura sheep averaged 63.6, 66.8, 77.1, 80.9, 20.7, 9.8, 30.3 and 6.3 cm respectively. Sex of the animal had significant effect on weight, height, body length and chest girth at 8 teeth stage. Phenotypic correlations of body weight with height, chest girth and paunch girth ranged from 0.76±0.04 to 0.88±0.03 and regression of weight on these body measurements ranged from 0.63±0.02 to 0.98±0.05.

SummaryThis study was undertaken in order to characterize the Ponwar breed and to establish its present status so that suitable breeding strategies and conservation models could be suggested for the overall improvement of the breed.The Ponwar is a draught cattle breed and is native to the Pilibhit District of Uttar Pradesh. The breeding tract lies between latitude 28°4' and 28°8' North and between longitude 79°0' and 80°4' East. The coat colour of these animals is brown or black with white patches in varying proportions. The tail switch is white in black animals and black in those having a greater proportion of white patches. The body is small, compact and non-fleshy, the face is small and narrow and the ears are small. The horns are small to medium and curve inward with pointed tips. The hump is small in females and developed in males. The tail is long and reaches to below the hock. Cows have small udders and teats. The animals of this breed possess an aggressive temperament.The milk production of the Ponwar cows is low, i.e. about 0.5 to 2.5 kg per day for a lactation period of 8 to 10 (average 8.9±0.1) months. Lactation milk yield averaged 462.5±12.1 kg. The age at first calving ranged from 40 to 60 months and the inter-calving period averaged 12.6±0.1 months. The service period in Ponwar cattle varied from 60 to 100 days. The cows remained dry for average of 110.0±2.6 days. Bullocks of this breed can transport an 800 to 1 000 kg load up to 10 kilometres easily. They can plough 0.4 hectares of land in a day working for 6 to 8 hours. Body length, height at wither and heart girth in adult cows averaged 97.1±0.5, 109.0±0.4 and 140.6±0.5 cm, respectively. The animals recorded in the different villages had similar average body measurements corresponding to their category. The survey revealed that about 21% of total cattle population was of Ponwar breed in Puranpur Tehsil. The approximate Ponwar population in the entire breeding tract was estimated as 10 667.

This is the first morphological comparative study between local horses and mules from Arauca, Colombia. It was realized to compare morphological traits between both species by analysing 15 adult mules (7 males and 8 females) and 150 adult horses (137 males and 13 females), with an age interval from 2 to 22 years. Data consisted of 24 different body quantitative traits which can explain the body conformation: thoracic circumference, body length (BL), thoracic depth and width, withers height (WH), sternum height, shoulders width, chest width, forelimb cannon perimeter and length, head length and width, skull length and width, face length and width, ear length and width, loin height, croup height (CrH), width and length, dock height (DoH), and hock height. Heart girth circumference, body length, withers height, croup height, and dock height were the most discriminative traits, showing statistical differences between species. The formula is X = (BL × 0.402) + (WH × 0.323) + (CrH × 0.352) + (DoH × 0.384). A value of X > 184.5 assigns with total certainty that a skeleton belongs to a horse, and if X < 174.0, it is a mule. The proposed formula has a 100% specificity but a 71.4% sensibility for mules and an 84.4% for horses into the rank of 174.0–184.5. Therefore, results demonstrate that some postcranial anatomical elements of Equus could give enough information for a bone differentiation between horses and mules, at least in animals from the Araucan region, but the main interest is that it reflects the possibility to differentiate morphometrically both species from bone remains when horses and mules were sympatric.

Pseudomonas aeruginosa is a widely represented species of bacteria possessing of a pathogenic potential. This infectious agent is causing wound infections, fibrotic cystitis, fibrosing pneumonia, bacterial sepsis, etc. The microorganism is highly resistant to antiseptics, disinfectants, immune system responses of the body. The responses of a quorum sense of this kind of bacteria ensure the inclusion of many pathogenicity factors. The analysis of the scientific literature made it possible to formulate four questions concerning the role of biofilms for the adaptation of P. aeruginosa to adverse environmental factors: Is another person appears to be predominantly of a source an etiological agent or the source of P. aeruginosa infection in the environment? Does the formation of biofilms influence on the antibiotic resistance? How the antagonistic activity of microorganisms is realized in biofilm form? What is the main function of biofilms in the functioning of bacteria? A hypothesis has been put forward the effect of biofilms on the increase of antibiotic resistance of bacteria and, in particular, P. aeruginosa to be secondary in charcter. It is more likely a biofilmboth to fulfill the function of storing nutrients and provide topical competition in the face of food scarcity. In connection with the incompatibility of the molecular radii of most antibiotics and pores in biofilm, biofilm is doubtful to be capable of performing a barrier function for protecting against antibiotics. However, with respect to antibodies and immunocompetent cells, the barrier function is beyond doubt. The biofilm is more likely to fulfill the function of storing nutrients and providing topical competition in conditions of scarcity of food resources.

AbstractThe aim of this work is to obtain diverse morphometric data from digitized 3D models of scientifically accurate palaeoreconstructions of theropods from eight representative families. The analysed polyvinyl chloride (PVC) models belong to the genera Coelophysis, Dilophosaurus, Ceratosaurus, Allosaurus, Baryonyx, Carnotaurus, Giganotosaurus, and Tyrannosaurus. The scanned 3D models were scaled considering different body-size estimations of the literature. The 3D analysis of these genera provides information on the skull length and body length that allows for recognition of major evolutionary trends. The skull length/body length in the studied genera increases according with the size of the body from the smallest Coelophysis with a ratio of 0.093 to ratios of 0.119–0.120 for Tyrannosaurus and Giganotosaurus, the largest study theropods. The study of photogrammetric 3D models also provides morphometric information that cannot be obtained from the study of bones alone, but knowing that all reconstructions begin from the fossil bones, such as the surface/volume ratio (S/V). For the studied theropod genera surface/volume ratio ranges from 35.21 for Coelophysis to 5.55 for Tyrannosaurus. This parameter, closely related to the heat dissipation, help in the characterization of the metabolism of extinct taxa. Accordingly, slender primitive forms of the Early Jurassic (i.e. Coelophysis and Dilophosaurus) had relatively smaller skulls and higher mass-specific metabolic rates than the robust large theropods of the Cretaceous (i.e. Giganotosaurus and Tyrannosaurus). This work presents a technique that, when applied to proper dinosaur models, provides extent and accurate data that may help in diverse study areas within the dinosaur palaeontology and palaeobiology.

The Ideal

The analysis of motivational systems underlying temporal organisation in animal behaviour has relied primarily on two conceptual functional frameworks: Homeostasis and biological clocks. Homeostasis is one of the most general and influential concepts in physiology. Walter Cannon introduced homeostasis as a universal regulatory principle which animals employ to maintain constancy of their ‘internal milieu’ in the face of challenges and perturbations from the external environment. Cannon spoke of “The Wisdom of the Body”, the collective of responses designed to defend the ideal internal state against those perturbations.

Object. Transthoracic endoscopic T2–3 sympathectomy is currently the treatment of choice for palmar hyperhidrosis. Compensatory sweating of the face, trunk, thigh, and sole of the foot was found in more than 50% of patients who underwent this procedure. The authors conducted this study to investigate the associated intraoperative changes in plantar skin temperature and postoperative plantar sweating. Methods. One hundred patients with palmar hyperhidrosis underwent bilateral transthoracic endoscopic T2–3 sympathectomy. There were 60 female and 40 male patients who ranged in age from 13 to 40 years (mean age 21.6 years). Characteristics studied included changes in palmar and plantar skin temperature measured intraoperatively, as well as pre- and postoperative changes in plantar sweating and sympathetic skin responses (SSRs). In 59 patients (59%) elevation of plantar temperature was demonstrated at the end of the surgical procedure. In this group, plantar sweating was found to be exacerbated in three patients (5%); plantar sweating was improved in 52 patients (88.1%); and no change was demonstrated in four patients (6.8%). In the other group of patients in whom no temperature change occurred, increased plantar sweating was demonstrated in three patients (7.3%); plantar sweating was improved in 20 patients (48.8%); and no change was shown in 18 patients (43.9%). The difference between temperature and sweating change was significant (p = 0.001). Compared with the presympathectomy rate, the rate of absent SSR also significantly increased after sympathectomy: from 20 to 76% after electrical stimulation and 36 to 64% after deep inspiration stimulation, respectively (p < 0.05). Conclusions. In contrast to compensatory sweating in other parts of the body after T2–3 sympathetomy, improvement in plantar sweating was shown in 72% and worsened symptoms in 6% of patients. The intraoperative plantar skin temperature change and perioperative SSR demonstrated a correlation between these changes.

SummaryThe results are presented of a method of generalized distances calculated by a noncentral χ2 test and applied to compare 63 twin pairs and 196 sib pairs. The advantage of this method in biometrical analysis lies in the fact that several measurements can be utilised simultaneously. Besides, it takes into account the distance of each relative to the centre of the population and also has the advantage of permitting the comparison of distances between pairs of relatives whatever their age or sex.Generalized distances were calculated for four measurements of the head, five of the body and eleven of the face. For all three sets of measurements the influence of genetical factors was demonstrated. The body seems less influenced by environmental factors and more conditioned by genetic ones.

AbstractA new nematode species,Philometroides acreanensisn. sp. (Philometridae), is described from female specimens recovered from the stomach wall of the freshwater catfishPimelodus blochiiValenciennes (Pimelodidae) collected in the Acre River (Amazon River basin), Acre State, Brazil. Based on examination by light and scanning electron microscopy, the new species differs from the two other South American congeneric species mainly in the body length of the gravid female (240–280 mm), the length of the oesophagus (1.25 mm in holotype) representing 0.5% of the entire body length, the range of cuticular embossment, as well as the location in the host (stomach), order of the fish host (Siluriformes) and the geographical distribution (Amazon River drainage system). This is the third known species ofPhilometroidesYamaguti, 1935 reported from South America. A key to species ofPhilometroidesoccurring in the fish of America is provided.
