The aim of the present study was to develop a treatment protocol for the precise synchronization of oestrus that would avoid the development of persistent dominant ovarian follicles. Bos indicus heifers, in which oestrous cycles had been presynchronized, were allocated randomly, according to the day of their oestrous cycle, to one of five treatment groups. All heifers received a subcutaneous ea...

Supernova 2004dj in the nearby spiral galaxy NGC2403 was detected optically in July 2004. Peaking at a magnitude of 11.2, this is the brightest supernova detected for several years. Here we present Multi-Element Radio Linked Interferometer Network (MERLIN) observations of this source, made over a four month period, which give a position of R.A. = 073717.044, Dec = +653557. 84 (J2000.0). We also...

Sir, Abnormal keratinization of the distal part of the hair follicle can prevent emergence of the growing hair from the follicle and lead to spiral growth within a hyperkeratotic papule, socalled ``rolled hairs'' (1). Rolled hairs have been reported in patients with keratosis pilaris (1), neurodermatitis (1), palmoplantar keratoderma (2), and hypertrichosis (3). The disorder has also been assoc...

Improvisational play methods encourage collaboration, communication and connection amongst groups. Learning can also be enhanced by the basic elements of improvisation; spontaneity, flexibility, and a willingness to experiment and take risks. Soliciting input from a diverse range of perspectives and building an environment based on trust also stimulates the efficacy and creativity of the group ...

With a sample of new technology ventures in China, we investigated the contingent effect of strategic decision comprehensiveness on new product performance and product quality. The relationship between strategic decision comprehensiveness and new product performance was negatively moderated by technology uncertainty but positively moderated by demand uncertainty. The effect of decision comprehe...

Tumor-intrinsic immuno-resistance is a prerequisite for emergence of follicular lymphomas. Here we show that in vitro, such cells are more resistant to immune cytolysis when grown as follicle-mimicking tridimensional aggregates than when grown as cell suspensions. So in patients, this innate adaptation to tumor immunity might precede its selective pressure.

Analogs of gonadoliberin (GnRH) are widely used in cattle to synchronize estrus and to induce ovulation, as well as for the treatment of ovarian cysts. The aim of this study was to compare the plasma profiles of LH and progesterone and the follicular dynamics in response to the administration of gonadorelin, lecirelin, or buserelin at the dose recommended to induce ovulation. In addition, the b...
