Abstract
Preclinical models suggested that activating mutations of the PIK3CA gene are associated with sensitivity to inhibitors of the mammalian target of rapamycin (mTOR). In breast cancers, PIK3CA mutations are associated with estrogen receptor (ER) positivity. We therefore performed an open-label single arm phase II study of the rapamycin analog, temsirolimus, at a dose of 25 mg weekly, in women with pretreated breast cancers that were positive for ER, PR, or HER2. Archived formalin-fixed paraffin embedded tumor was collected for immunohistochemical evaluation of components of the PI3K/Akt/mTOR pathway and PIK3CA mutation analysis. Thirty-one patients were enrolled. There were no major objective responses; however, three patients had stable disease for over 24 weeks. Twenty-three tumor samples were available for mutational analysis. There were five tumors with PIK3CA mutations; no association was found between prolonged stable disease and PIK3CA mutation or any immunohistochemical marker. There was a trend toward improved progression free survival (PFS) for patients with positive nuclear staining for phospho-Akt308. One patient remains on study four and a half years after starting therapy; her tumor did not have a PIK3CA mutation. We conclude that single agent temsirolimus has minimal activity in a population of women with heavily pretreated breast cancer. We found no evidence that either absence of immunohistochemical staining for PTEN or mutations in the hotspot domains of PIK3CA in the primary tumor were associated with clinical benefit.

Abstract
Viability of cloned and transgenic piglets is seriously compromised and one obvious reason could be malformations. The aim of the present study was therefore to describe gross pathological conditions in dead pre-weaned piglets born after transfer to Large White (LW) recipients of cloned (LW donor cells) or transgenic (Yucatan or Göttingen donor cells) embryos. Donor cells were fibroblasts and the Göttingen and Yucatan cells were made transgenic with 1 of 5 genes known to dispose for different human diseases. Handmade cloning was used to produce embryos that after 5 to 6 days of in vitro culture were transferred surgically to 108 LW sows 4 days after their natural heat. Of these, 21 sows delivered cloned LW piglets, whereas 17 and 16 sows, respectively, delivered transgenic Göttingen and Yucatan piglets. Stillborn and dead pre-weaned piglets were necropsied and malformations registered. Data were analysed by Fisher's exact test with a significance level of P < 0.05. In the 54 litters, total litter size ranged from 1 to 22 piglets (mean 5.4 ± 0.5) and the overall mortality rate until weaning on day 28 was 59%. Malformations were found in piglets from 38 litters where an average of 35% of the piglets showed malformations (between 8 and 100%). In those litters, 1 to 7 piglets had 1, 2, or several malformations (Table 1). The malformation rate in the autopsied transgenic Göttingen was 58% and in Yucatan 46%; these were significantly higher than in the autopsied cloned LW piglets with 18%. Some of the malformations seemed to be related to breed and/or transgene; for instance, heart malformations were most frequent in Yucatan litters (70%) independent of the transgene, whereas gallbladder and gonad malformations were more frequent in various litters with the same transgene. These results show that the use of cloning in pigs results in a considerable loss of piglets due to malformations and transgenic transformation of the cells used for cloning superimpose on this problem. In combination, these elements could seriously compromise the use of pigs as a model for human diseases and the choice of breeds and also transgenes for this kind of work should be considered carefully. However, further improvements in production of cloned/transgenic embryos may ultimately reduce the incidence of malformations.

Abstract
We report the first direct measurement of the internal magnetic field structure associated with a 3D helical equilibrium generated spontaneously in the core of an axisymmetric toroidal plasma containment device. Magnetohydrodynamic equilibrium bifurcation occurs in a reversed-field pinch when the innermost resonant magnetic perturbation grows to a large amplitude, reaching up to 8% of the mean field strength. Magnetic topology evolution is determined by measuring the Faraday effect, revealing that, as the perturbation grows, toroidal symmetry is broken and a helical equilibrium is established.

Abstract
The perinatal mortality of cloned animals is a well-known problem. In the present retrospective study, we report on mortality of cloned transgenic or non-transgenic piglets produced as part of several investigations. Large White (LW) sows (n = 105) received hand-made cloned LW or minipig blastocysts and delivered either spontaneously or after prostaglandin induction followed by either Caesarean section or vaginal birth. The overall pregnancy rate was 62%, with 26% of pregnancies terminating before term. This resulted in 48 deliveries. The terminated pregnancies consisted of 12 abortions that occurred at 35 ± 2 days gestation and five sows that went to term without returning to heat and then by surgery showed the uterus without fetal content. The gestation length was for sows with LW piglets that delivered by Caesarean section or vaginally was 115.7 ± 0.3 and 117.6 ± 0.4 days, respectively. In sows with minipiglets, the gestation length for those delivered by Caesarean section or vaginally 114.4 ± 0.2 and 115.5 ± 0.3 days, respectively. Of the 34 sows that delivered vaginally, 28 gave birth after induction, whereas 6 farrowed spontaneously. Of the 14 sows that delivered after Caesarean section and in the five empty sows, the endometrium and placenta showed severe oedema. Piglet mortality following vaginal delivery was higher than after Caesarean section (31% v. 10%, respectively; P < 0.001). When vaginal delivery occurred spontaneously, the stillborn rate was greater than after induced delivery (56% v. 24%, respectively; P < 0.0001). Internal organ weights were recorded for seven cloned LW piglets and six normal piglets. The relative weight of the heart, liver, kidneys and small intestine was found to be reduced in the cloned piglets (P < 0.05). The present study demonstrates extensive endometrial oedema in sows pregnant with cloned and transgenic piglets, as well as in empty recipients, at term. The growth of certain organs in some of the cloned piglets was reduced and the rate of stillborn piglets was greater in cloned and transgenic piglets delivered vaginally, possibly because of oedema of the fetal-maternal interface.

Abstract
The Korean rockfish (Sebastes schlegeli) is an important commercial fish that is widely used in aquaculture. We isolated and characterized 18 polymorphic microsatellite loci from the Korean rockfish using a (GT)(13)-enriched genomic library. Polymorphism was assessed in 48 individuals from a single population collected from the northern coastal waters of the Yellow Sea. The observed and expected heterozygosities ranged from 0.0244 to 0.7660 (mean 0.4194) and 0.0244 to 0.8758 (mean 0.5002), respectively. Polymorphism at these loci indicated from two to 15 alleles (mean 5.7); 14 of 18 loci conformed to Hardy-Weinberg equilibrium. These markers should be useful for management and conservation studies of this species.
