G,Q and R-banding pattern comparisons between the Murrah type of Bubalus bubalis L. (2n = 50) and the Holstein Friesian breed of Bos taurus L. (2n = 60) chromosomes revealed that the autosomes are similar in both species; in the former, the five pairs of submetacentrics correspond to centric fusions of chromosomes 1-29, 2-22, 8-19, 5-28 and 16-25 in the latter. Silver staining on somatic cells of buffalo revealed telomeric Ag-NORs located on six pairs of autosomes, identified as 3p, 4p, 8, 21, 23 and 24. Only one pair of nucleolus organizer chromosomes is common to both species, namely the 4p of buffalo which corresponds to the 28 of cattle. The remaining NORs are located on different pairs. Out of 18 individuals, the number of Ag-NORs per cell varied between 3 and 10, with a mean value of 6.3 ± 1.7; the mean number of nucleolar associations per cell was between 0.1 and 1.8. In the total population of 317 cells the two variables followed the binomial and the Poisson distributions, respectively, and their correlation coefficient was not statistically significant (r = +0.36). In addition to the mean number of Ag-NORs, the mean number of nucleolar associations per cell should be used for a better understanding of the differences among individuals.

Bos taurus cattle with high resistance to the tick Boophilus micro plus, whether free-grazing or in covered pens, had significantly more arteriovenous anastomoses (A VA) in their skin than did animals of low resistance. These differences in number of A VA associated with resistance level were most marked above the level of the sebaceous gland in the neck region, an area favoured for tick feeding. In this skin layer, the number of AVA in low-resistance animals (4�0�0�4 per 2�1 mm) was significantly lower than in animals of high resistance (12�3 � 2�2 per 2�1 mm) while the mean value for the naive animals (8�2 � 1 �9 per 2�1 mm) was intermediate. No differences in morphology of AVA were detectable between the three groups using light microscopy.

Estimates of microbial crude protein (MCP) production by ruminants, using a method based on the excretion of purine derivatives in urine, require an estimate of the excretion of endogenous purine derivatives (PD) by the animal. Current methods allocate a single value to all cattle. An experiment was carried out to compare the endogenous PD excretion in Bos taurus and high-content B. indicus (hereafter, B. indicus) cattle. Five Holstein–Friesian (B. taurus) and 5 Brahman (> 75% B. indicus) steers (mean liveweight 326 ± 3.0 kg) were used in a fasting study. Steers were fed a low-quality buffel grass (Cenchrus ciliaris; 59.4 g crude protein/kg dry matter) hay at estimated maintenance requirements for 19 days, after which hay intake was incrementally reduced for 2 days and the steers were fasted for 7 days. The excretion of PD in urine was measured daily for the last 6 days of the fasting period and the mean represented the daily endogenous PD excretion. Excretion of endogenous PD in the urine of B. indicus steers was less than half that of the B. taurus steers (190 µmol/kg W0.75.day v. 414 µmol/kg W0.75.day; combined s.e. 37.2 µmol/kg W0.75.day; P < 0.001). It was concluded that the use of a single value for endogenous PD excretion is inappropriate for use in MCP estimations and that subspecies-specific values would improve precision.

The present study investigates the prevalence and type of anaemia in Chinese female cotton mill workers. The prevalence of anaemia is reported in 447 non-pregnant female workers aged between 19 and 45 years. The mean value for haemoglobin (Hb) was 123 (SD 15) g/l and 150 of the total 447 subjects had Hb values below 120 g/l; thus 34% of the population was anaemic according to World Health Organization (WHO, 1975) criteria. The mean value for free erythrocyte protoporphyrin (FEP) was 419 (SD 215) μg/l; 55% of the total population had FEP values higher than 350 μg/l and 72% among the anaemic subjects. Serum ferritin (SF) was tested in all the women with a Hb value less than 120 g/l and 71 % of them had SF values below 12·0 μg/ls. Eighty women diagnosed as either Fe deficient or with Fe-deficient anaemia were selected for a diagnostic supplementation trial. They were randomly assigned to FeSO4(60 or 120 mg Fe/d) or placebo treatment for 12 weeks. Fe supplementation increased mean Hb values from 114 to 127 g/l (P< 0·001) and SF levels from 9·7 to 30·0 μg/l (P< 0·001), and decreased mean FEP values from 570 to 277 μg/l (P< 0·001). The response rate of Hb in the whole Fe-treated group or Fe-treated subjects with an Hb level less than 120 g/1 was 90 % or 92 % respectively. These findings indicate that the type of anaemia in this population was mainly Fe deficiency. It was also found that in this population the severity of anaemia, not the prevalence, was significantly related to the use of intra-uterine devices (IUD).

<p><strong>Abstract.</strong> Era-Interim (ECMWF Re- analysis) is a global reanalysis atmospheric product which is being continuously updated in real time since 1979. It is also termed as third generation reanalysis product. The Era–Interim gives meteorological products like precipitation, temperature, etc. In the present work, 3-hourly Era–Interim product for the entire India is compared with gridded data provided by IMD for period 1979&amp;ndash;2013 and APHRODITE data for period 1979&amp;ndash;2007, respectively. The comparison is done on seasonal basis and the seasons are taken based on the pattern of rainfall, hence, the four seasons selected are DJF (December, January &amp; February), MAM (March, April &amp; May), JJAS (June, July, August &amp; September) and ON (October &amp; November). In the methodology the Era-Interim 3-hourly products are converted into the daily products and then it is used to form seasonal images for each year. All the images are then taken to form four images as outcome for the entire study period which represents the average rainfall (mm/day) for the entire region. This is being done for the IMD and for the APHRODITE Data. All the four images are then taken for the comparison with the reference images of the IMD 0.5º<span class="thinspace"></span>&amp;times;<span class="thinspace"></span>0.5º gridded rainfall data and with the APHRODITE 0.5º<span class="thinspace"></span>&amp;times;<span class="thinspace"></span>0.5º gridded rainfall data. The correlation coefficient and the RMSE for each season is calculated. The mean value is compared with the mean of IMD and APHRODITE rainfall products, respectively and a bias in mean is also calculated along with the scatter plots of Era-Interim with the reference datasets. The Era &amp;ndash; Interim data came out with suitable comparative parameters with high correlation coefficient and low RMSE value in certain regions and in specific seasons. Scatter plots have also given good correlation in all the seasons. Bias maps have also shown very less bias in specific seasons for certain regions. The suitability maps prepared for the study region also shows that most of the region lies in most suitable range and very less in unsuitable range.</p>

O objetivo do experimento foi testar os efeitos da somatotrofina bovina (BST) no recrutamento de folículos ovarianos, durante o ciclo estral de vacas. Foram utilizadas seis vacas não lactantes Bostrurus taurus antes do experimento, os animais foram submetidos a exames ginecológicos completos, estando o escore médio da condição corporal dos animais em 3,0. As vacas foram divididas ao acaso em dois grupos: G1 - três animais, tratados com somatotrofina bovina recombinante (BST) 500 mg, de liberação lenta com vitamina E (IM); G2 - três vacas controles, que receberam 10 ml (IM) de solução fisiológica estéril como placebo. Para sincronizar o estro base das vacas foram utilizados implantes de norgestomet de 3 mg, na face externa da orelha (SC). O implante permaneceu por 10 dias seguidos nos animais de ambos os grupos e na sua retirada, utilizou-se uma dose de 500 ì g de cloprostenol (IM). No 3º dia pós estro os animais foram tratados respectivamente com BST (G1) e solução fisiológica para os controles (G2). Diariamente, a partir do dia do estro base até o próximo estro, os ovários das vacas foram “monitorados¨ ultrassonograficamente com vistas ao número de folículos recrutados em cada onda folicular, verificação do folículo dominante (FD) e sua evolução, bem como o diâmetro individual dos outros folículos. Para o monitoramento folicular ovariano, foi utilizado aparelho de ultrassonografia e transdutor linear de 5.0 megahertz. Foram detectados durante o ciclo estral em média 8,5 e 8,3 folículos maiores que 4,0 mm de diâmetro nos animais dos G1 e G2 respectivamente; em torno do 10º dia pós tratamento observou-se o maior número de folículos recrutados em ambos os grupos; houve cinco animais com 2 ondas foliculares e um com três, sendo o número de folículos recrutados em cada onda como segue (G1 e G2, respectivamente): 1ª onda 7,6 e 7,0; 2ª onda 8,3 e 8,0; dia da detecção do 1º FD 1,0 e 1,6 dias ; 2º FD 8,6 e 9,0 dias; duração da 1ª onda folicular 11,6 e 9,6 dias; da 2ª onda folicular 8,0 e 7,6 dias; diâmetro máximo do 1º FD 18,2 e 15,8 mm; do 2º FD 16,6 e 15,0 mm; diâmetro do corpo lúteo (CL) do estro base 30,7 e 24,3 mm; dia do diâmetro folicular máximo pós tratamento do FD da 1ª onda: 8,6º e 10,3º; do 2º FD 18,6º e 16,6º dia. Baseados nesses resultados concluiu-se que a aplicação isolada de BST no 3º dia do ciclo estral, não exerceu influência entre os grupos relativamente ao recrutamento folicular ovariano, à exceção da duração da fase luteal, a qual alongou-se significativamente (p0,05) entre os grupos. A administração do BST expressou uma tendência em maior número de folículos recrutados (p>0,05). The bovine somatotrophin in the estrus cycle and its relationships with the ovarian follicular recruitment in cows Abstract The aim of this research was to evaluate the effects of the bovine somatotropin (BST) on the ovarian follicular wave of estrus cycle in cows. Six nonlactating cows Bos taurus taurus, from which four Holstein Friesian, one Jersey and one Holstein-pingzgauer breed, were used. The cows were submitted to a genital examination prior to the experiment, the mean body score condition observed being 3.0. The animals were maintained on oat and azeven pasture, with corn silage and mineral suplementation ad libitum. The cows were ramdomly divided in two groups: G1 – three animals treated with 500 mg BST in the third day post estrus; G2 - three control cows (10 ml physiologic solution). Norgestomet implants on the ear internal face and intramuscular PGF2 alpha were used to perform the estrus synchronization. The bovine ovaries were daily scanned by ultrasound, from the estrus day to the following estrus, in order to detect the follicular development in each follicular wave. During the estrus cycle 8.5 and 8.3 follicles bigger than 4.0 mm of diameter were detected in G1 and G2, respectively. The highest number of recruitment follicles occurred in both groups around the 10th day post treatment; five cows had two follicular waves and the other, one. The number of recruitment follicles in each wave for G1 and G2 group was respectively: 1st wave, 7.6 and 7.0; 2nd wave, 8.3 and 8.0; 1st dominant follicle (FD) detection 1.0 and 1.6 days; 2nd FD detection 8.6 and 9.0 days; 1st follicular wave length, 11.6 and 9.6 days; 2nd follicular wave, 8.0 and 7.6 days. The maximum diameter of the 1st FD was 18.2 and 15.8 mm; from the 2nd FD 16.6 and 15.0 mm; CL diameter from the estrus basis, 30.7 and 24.3 mm; at the day of the major follicular diameter post treatment of the 1st FD (1st wave) 8.6 and 10.3; from the 2nd wave, FD 18.6 and 16.6 day, respectively. In conclusion, the isolated administration of BST in the 3rd day of the estrus cycle did not influence the follicular recruitment between groups, except on the length of the luteal phase (p0.05) between groups. The BST effect appointed a tendency on the greater number of recruitment follicles (p>0,05).

Comparisons of liveweight gain, carcass tissue weight gain and carcass composition were made between buffalo (Bubalus bubalis) steers and Angus, Friesian and Hereford steers, and among the three Bos taurus breeds following similar periods of lot-feeding. After a high-grain concentrate feeding regime for 182–205 days, mean daily liveweight gains were Herefords, 1.08 kg; Friesians, 0.88 kg; Angus, 0.72 kg; and buffaloes, 0.67 kg. At the commencement of lot-feeding, mean carcass composition was similar among Bos breeds whilst the buffaloes had higher proportions of muscle and bone and a lower proportion of fat. After lot-feeding there were slight changes only in the mean carcass composition of the buffaloes, whereas there were large changes in and among Bos breeds. An analysis of carcass weight gain showed that liveweight gain did not reflect differential tissue growth. The buffaloes, with a liveweight gain of 87 kg, gained 31.7 kg muscle and 9.3 kg fat. Corresponding gains in Bos breeds were Herefords, 141 kg liveweight for 31.3 kg muscle and 62.7 kg fat; Friesians, 108 kg liveweight for 3 2 8 kg muscle and 19.3 kg fat; and Angus, 98 kg liveweight for 12.5 kg muscle and 57.8 kg fat. The respective increases in weight of muscle and fat expressed as percentages of liveweight increase were buffaloes, 36.4 and 10.7; Herefords, 22.2 and 44.5; Friesians, 30.4 and 17.9; and Angus, 12.8 and 59.0. Regression equations for percentages of muscle, bone and fat on chilled carcass weight are given for the three Bos taurus breeds and the buffaloes.

Pd-Ce alloys exhibit various anomalies in physical properties due to mixed valences of Ce, and the anomalies are thought to be strongly related with the crystal structures. Since Pd and Ce are both heavy elements, relative magnitudes of (fcc-fpd) are so small compared with <f> that superlattice reflections, even if any, sometimes cannot be detected in conventional x-ray powder patterns, where fee and fpd are atomic scattering factors of Ce and Pd, and <f> the mean value in the crystal. However, superlattices in Pd-Ce alloys can be analyzed by electron microscopy, thanks to the high detectability of electron diffraction. In this work, we investigated modulated superstructures in alloys with 12.5 and 15.0 at.%Ce.Ingots of Pd-Ce alloys were prepared in an arc furnace under atmosphere of ultra high purity argon. The disc specimens cut out from the ingots were heat-treated in vacuum and electrothinned to electron transparency by a jet method.

The relative partition coefficients of krypton and xenon, and the regional blood flow in 27 superficial malignant tumour nodules in 22 patients with diagnosed tumours were measured using the 85mKr- and 133Xe-clearance method. In order to minimize the effect of biological variables on the measurements the radionuclides were injected simultaneously into the tumour. The distribution of the radiotracers was assumed to be in equilibrium at the beginning of the experiment. The blood perfusion was calculated by fitting a two-exponential function to the measuring points. The mean value of the perfusion rate calculated from the xenon results was 13 ± 10 ml/(100 g-min) [range 3 to 38 ml/(100 g-min)] and from the krypton results 19 ± 11 ml/(100 g-min) [range 5 to 45 ml/(100 g-min)]. These values were obtained, if the partition coefficients are equal to one. The equations obtained by using compartmental analysis were used for the calculation of the relative partition coefficient of krypton and xenon. The partition coefficient of krypton was found to be slightly smaller than that of xenon, which may be due to its smaller molecular weight.
