Abstract
During decidualization, endometrial stromal cells undergo reticular stress (RS) and unfolded protein response (UPR), allowing the endoplasmic reticulum-expansion and immunomodulators production. Physiological RS generates the activation of sensing proteins, inflammasome activation and mature-IL-1β secretion, associated with pro-implantatory effects. We focus on the impact of RS and UPR on decidualized cells and whether they induce a physiological sterile inflammatory response through IL-1β production. Human endometrial stromal cell line (HESC) after decidualization treatment with MPA + dibutyryl-cAMP (Dec) increased the expression of RS-sensors (ATF6, PERK and IRE1α) and UPR markers (sXBP1 and CHOP) in comparison with Non-dec cells. Then we found increased NLRP3 expression in Dec cells compared with Non-dec cells. In fact STF-083010 (an IRE1α inhibitor) prevented this increase. Downstream, increased levels of active caspase-1 on Dec cells were detected by FAM-Flica Caspase-1 associated with an increase in IL-1β production. Moreover, the treatment with STF-083010 decreased the invasion index observed in Dec cells, evaluated by an in vitro model of implantation. In endometrial biopsies from recurrent spontaneous abortion patients an increased expression of IRE1α was found in comparison with fertile women; while recurrent implantation failure samples showed a lower expression of sXBP1, TXNIP and NLRP3 than fertile women, suggesting that RS/UPR tenors might condition endometrial receptivity.

Abstract
This paper describes the development of stable drug delivery systems named layersomes. The layersomes are conventional liposomes coated with one or multiple layers of biocompatible polyelectrolytes in order to stabilise their structure. The formulation strategy is based on an alternative coating procedure of positive poly(lysine) (pLL) and negative poly(glutamic acid) (pGA) polypeptides on initially charged small unilamellar liposomes (SUVs). The size distribution and the zeta potential of the final entity depend on the number of polyelectrolyte layers and the charge of the last coating layer. Morphological studies were achieved by flux cytometry and cryo electron microscopy. Release studies of encapsulated hydrophilic 5(6)-carboxyfluorescein (5,6CF) in the presence of Triton or ethanol showed an increased membrane resistance of the layersomes compared to classical SUVs. Finally, encapsulation of piroxicam (PX) was performed with success.

Abstract
An observational prospective cohort study was conducted with a historical control group and 140 infertile women with the laparoscopic diagnosis of ovarian endometrioma over 1 cm diameter. The groups were comparable regarding age, duration of infertility, and disease severity. All patients had a follow-up of 12 months after treatment, and at least one patent tube. The laparoscopic group (group A) consisted of 46 woman, 35 of whom received suppressive treatment with danazol, Gestinone, or leuprolide acetate for 4 to 6 months. In the control group (group B), 94 women underwent diagnostic laparoscopy plus 6 months of danazol or Gestinone therapy. After 3 months, microsurgery by laparotomy was performed. During the follow-up, period 24 pregnancies were achieved in group A (52%) and 58 in group B (61%, chi2 0.796). Fifteen (48%) of 31 women with cysts 1 to 3 cm in group A conceived, as did 52 (62%) of 81 in group B. Nine (60%) of the 15 with cysts over 3 cm in group A, and 7 (58%) of 12 in group B conceived. No significant difference was found among the suppressive drugs in either group. Only 4 (36%) of the 11 women in group A not receiving suppressive treatment became pregnant. No significant difference (p >0.05) was found when comparing the combined treatment group (57%). According to the revised classification of endometriosis, 18 (51%) of 35 pregnancies were achieved in women with moderate disease in group A and 41 (64%) of 64 in group B. In those with severe disease, 6 (55%) of 11 became pregnant in group A and 17 (57%) of 30 in group B. There was no significant difference between the groups when comparing global results, ovarian endometrioma size, medical treatment, and severity of endometriosis. Given comparable surgical expertise, operative laparoscopy should be the procedure of choice in the treatment of ovarian endometrioma whenever possible, due to its recognized advantages.

Abstract
Monoclonal antibodies to tobacco mosaic virus that bind only to one end of the viral rods have been shown to recognize the surface of the protein subunit designated as the bottom, which contains the right radial and left radial alpha-helices. The specificity of the antibody binding was established by immunoelectron microscopy of complexes in which the 5' end of the RNA had been exposed at the bottom of the helical virus particle. These antibodies have been shown to bind to both ends of the stacked disk aggregate of TMV protein, which is therefore bipolar. The observations on the bipolarity of this structure are inconsistent with the presumption that stacked disks are formed by aggregation of polar two-layer disks.

Abstract
Various oncogenes or epidermal growth factor (EGF) induce transcription of a 1.9-kilobase RNA (transin RNA) in rat fibroblasts. The induction by EGF can be blocked by cycloheximide. Thus the response of the transin gene to EGF appears to require de novo protein synthesis. Transin RNA induction is specific to EGF, as neither insulin, platelet-derived growth factor, fibroblast growth factor, nor transforming growth factor beta could elicit the same response. However, transforming growth factor beta could block the EGF induction of transin RNA. Whereas the calcium ionophore A23187 and the tumor promoter TPA, either alone or administered together, did not increase transin RNA levels, TPA could synergise with a serum factor to effect such an increase. Dibutyryl cyclic AMP also induced transin RNA. Treatment of cells with the microfilament-disrupting agent cytochalasin B, but not the microtubule-disrupting agent colcemid, resulted in an increase in transin RNA levels, suggesting a role for the cytoskeleton in control of transin gene expression. The transin RNA does not contain repeated sequences and appears to be encoded by a single-copy gene. The protein sequence encoded by the last four exons of the transin gene shows some homology to two regions of the heme-binding protein hemopexin.

Abstract
A nucleosome-free region or gap containing the origin of replication and the transcriptional promoter elements is observed on 20 to 25% of the SV40 minichromosomes isolated at physiological ionic strength late in infection. We used the preferential sensitivity of the gapped minichromosomes to restriction enzymes to obtain sucrose gradient fractions containing 50 to 80% of gapped molecules. The same fractions are also enriched in RNA polymerase B (II) molecules engaged in transcription. Using electron microscopy, we demonstrate here that the transcriptional complexes are preferentially sensitive to restriction enzyme digestion, which indicate that they represent a subpopulation of the gapped minichromosomes.
