The importance of the gestation period for welfare of lambs: Maternal stressors and lamb vigour and wellbeing

The prenatal period is of critical importance in defining how individuals respond to their environment throughout life. Stress experienced by pregnant females has been shown to have detrimental effects on offspring behaviour, health and productivity. The sheep has been used extensively as a model species to inform human studies. However, in the farmed environment, the consequences for the lamb of the imposition of prenatal stresses upon the ewe have received much less attention. The stressors that pregnant ewes are most frequently exposed to include sub-optimal nutrition and those related to housing, husbandry and environment which may be either acute or chronic. A systematic review of the literature was adopted to identify material which had production-relevant maternal stressors and lamb outcomes. The current review focussed upon the lamb up to weaning around the age of 100 days and the results clearly demonstrate that stressors imposed upon the ewe have implications for offspring welfare and performance. Maternal under-nutrition (UN) in the last third of pregnancy consistently impaired lamb birth-weight and subsequent vigour and performance, while earlier UN had a variable effect on performance. Feeding the ewe above requirements did not have positive effects on lamb performance and welfare. Social and husbandry stressors such as transport, shearing, mixing and physiological treatments designed to mimic acute stress which would be considered disadvantageous for the ewe had positive or neutral effects for the lamb, highlighting a potential conflict between the welfare of the ewe and her lamb. This review also identified considerable gaps in knowledge, particularly in respect of the impact of disease upon the ewe during pregnancy and interactions between different stressors and the responses of ewe and lamb.

An optimized reverse-phase high performance liquid chromatographic method for evaluating percutaneous absorption of glucosamine hydrochloride

A relatively simple, selective, precise and accurate high performance liquid chromatography (HPLC) method based on a reaction of phenylisothiocyanate (PITC) with glucosamine (GL) in alkaline media was developed and validated to determine glucosamine hydrochloride permeating through human skin in vitro. It is usually problematic to develop an accurate assay for chemicals traversing skin because the excellent barrier properties of the tissue ensure that only low amounts of the material pass through the membrane and skin components may leach out of the tissue to interfere with the analysis. In addition, in the case of glucosamine hydrochloride, chemical instability adds further complexity to assay development. The assay, utilising the PITC-GL reaction was refined by optimizing the reaction temperature, reaction time and PITC concentration. The reaction produces a phenylthiocarbamyl-glucosamine (PTC-GL) adduct which was separated on a reverse-phase (RP) column packed with 5 microm ODS (C18) Hypersil particles using a diode array detector (DAD) at 245 nm. The mobile phase was methanol-water-glacial acetic acid (10:89.96:0.04 v/v/v, pH 3.5) delivered to the column at 1 ml min-1 and the column temperature was maintained at 30 degrees C. Galactosamine hydrochloride (Gal-HCl) was used as an internal standard. Using a saturated aqueous solution of glucosamine hydrochloride, in vitro permeation studies were performed at 32+/-1 degrees C over 48 h using human epidermal membranes prepared by a heat separation method and mounted in Franz-type diffusion cells with a diffusional area 2.15+/-0.1 cm2. The optimum derivatisation reaction conditions for reaction temperature, reaction time and PITC concentration were found to be 80 degrees C, 30 min and 1% v/v, respectively. PTC-Gal and GL adducts eluted at 8.9 and 9.7 min, respectively. The detector response was found to be linear in the concentration range 0-1000 microg ml-1. The assay was robust with intra- and inter-day precisions (described as a percentage of relative standard deviation, %R.S.D.) <12. Intra- and inter-day accuracy (as a percentage of the relative error, %RE) was <or=-5.60 and <or=-8.00, respectively. Using this assay, it was found that GL-HCl permeates through human skin with a flux 1.497+/-0.42 microg cm-2 h-1, a permeability coefficient of 5.66+/-1.6x10(-6) cm h-1 and with a lag time of 10.9+/-4.6 h.

Diversity and biology of polychaeta of Diopatra Genus

Os anelídeos poliquetas são elementos importantes em ambientes estuarinos e costeiros, pela sua elevada biodiversidade e abundância e pelo papel que têm nas cadeias tróficas. Algumas espécies são intensivamente exploradas para serem utilizadas como isco na pesca desportiva e profissional, como é o caso de Diopatra neapolitana. Apesar da importância económica, existem poucos estudos sobre a sua biologia e ecologia. No decorrer deste estudo foram identificadas duas outras espécies do género Diopatra em Portugal: D. marocensis, inicialmente descrita para a costa de Marrocos e cuja distribuição actual se sabe estender-se a toda a costa Portuguesa e Norte de Espanha e, D. micrura, espécie nova para a ciência. O presente estudo tem como objectivos principais estudar a diversidade e reprodução do género Diopatra, bem como a capacidade de regeneração da espécie D. neapolitana. Este trabalho aborda a distribuição espacial de D. marocensis ao longo da costa Portuguesa e descreve a espécie D. micrura, uma nova espécie do género Diopatra Audouin and Milne Edwards, 1833. As três espécies coabitam em águas transicionais, onde as espécies D. micrura e D. marocensis facilmente se confundem com juvenis de D. neapolitana. Foi realizada uma comparação morfológica e genética entre as três espécies. A espécie D. neapolitana coexiste em algumas áreas da Ria de Aveiro com a D. marocensis. Apesar destas duas espécies apresentarem padrões reprodutivos muito diferentes, Maio a Agosto é o período principal para a reprodução de ambas as espécies. D. neapolitana apresenta um desenvolvimento larvar planctónico, e os óocitos presentes na cavidade celómica são esverdeados e apresentam um diâmetro de 40-240 μm (média = 164.39±40.79 μm) e as fêmeas contêm no celoma milhares de óocitos. Contrariamente, a espécie D. marocensis reproduz-se por desenvolvimento directo no interior do tubo parental. Os óocitos observados no celoma são amarelos com um diâmetro entre 180 e 740 μm (média = 497.65 ± 31.38 μm) e o seu número varia entre 44 e 624 (276.85 ± 161.54). Por seu turno, o número de ovos observados no interior dos tubos varia entre 75 e 298, com um diâmetro entre 600 e 660 μm, e o número de larvas entre 60 e 194. A proporção machos: fêmeas foi de 1:1 para a população de D. neapolitana e entre 1:2 e 1:4 para a população de D. marocensis, em que as fêmeas dominam a população durante todo o ano. O estudo da capacidade de regeneração da espécie D. neapolitana, avaliada a partir de experiências de laboratório, revelou que esta espécie é capaz de sobreviver à perda de alguns setígeros. Durante a captura de D. neapolitana para vender como isco são normalmente cortados mais de 20 setígeros e de acordo com os nossos resultados a extremidade posterior que fica no tubo não é capaz de regenerar a extremidade anterior; a espécie consegue no entanto recuperar de ataques por predadores.

Reduced physical activity level and cardiorespiratory fitness in children with chronic diseases.

We aimed to compare physical activity level and cardiorespiratory fitness in children with different chronic diseases, such as type 1 diabetes mellitus (T1DM), obesity (OB) and juvenile idiopathic arthritis (JIA), with healthy controls (HC). We performed a cross-sectional study including 209 children: OB: n = 45, T1DM: n = 48, JIA: n = 31, and HC: n = 85. Physical activity level was assessed by accelerometer and cardiorespiratory fitness by a treadmill test. ANOVA, linear regressions and Pearson correlations were used. Children with chronic diseases had reduced total daily physical activity counts (T1DM 497 +/- 54 cpm, p = 0.003; JIA 518 +/- 28, p < 0.001, OB 590 +/- 25, p = 0.003) and cardiorespiratory fitness (JIA 39.3 +/- 1.7, p = 0.001, OB 41.7 +/- 1.2, p = 0.020) compared to HC (668 +/- 35 cpm; 45.3 +/- 0.9 ml kg(-1) min(-1), respectively). Only 60.4% of HC, 51.6% of OB, 38.1% of JIA and 38.5% of T1DM children met the recommended daily 60 min of moderate-to-vigorous physical activity. Low cardiorespiratory fitness was associated with female gender and low daily PA. Children with chronic diseases had reduced physical activity and cardiorespiratory fitness. As the benefits of PA on health have been well demonstrated during growth, it should be encouraged in those children to prevent a reduction of cardiorespiratory fitness and the development of comorbidities.
