Abstract
With the increasing prevalence of obesity in women of reproductive age there is a need to understand the ramifications of this on offspring. The purpose of this study is to investigate the programming effects of maternal obesity during preconception and the preconception/gestational period on adiposity and adipose tissue inflammation in offspring using an animal model. Adult female C57Bl/6J mice were assigned either normal diet, high fat diet (HFD) prior to pregnancy, or HFD prior to and through pregnancy. Some offspring were maintained on normal diet while others started HFD later in life. Offspring were assessed for body composition and metabolic responses. Lipid storing tissues were evaluated for expansion and inflammation. Male offspring from the preconception group had the greatest weight gain, most subcutaneous adipose tissue, and largest liver mass when introduced to postnatal HFD. Male offspring of the preconception/gestation group had worsened glucose tolerance and an increase in resident (CD11c−) adipose tissue macrophages (ATMs) when exposed to postnatal HFD. Female offspring had no significant difference in any parameter between the diet treatment groups. In conclusion, this study demonstrates that prenatal and pregnancy windows have independent programming effects on offspring. Preconception exposure affects body composition and adiposity while gestation exposure affects metabolism and tissue immune cell phenotypes.

Abstract
PURPOSE To retrospectively assess outcomes and to identify prognostic factors in patients diagnosed with intermediate-risk (IR) prostate cancer (PCa) treated with primary external beam radiotherapy (EBRT). MATERIALS AND METHODS Data were obtained from the multi-institutional Spanish RECAP database, a population-based prostate cancer registry in Spain. All IR patients (NCCN criteria) who underwent primary EBRT were included. The following variables were assessed: age; prostate-specific antigen (PSA); Gleason score; clinical T stage; percentage of positive biopsy cores (PPBC); androgen deprivation therapy (ADT); and radiotherapy dose. The patients were stratified into one of three risk subcategories: (1) favourable IR (FIR; GS 6, ≤ T2b or GS 3 + 4, ≤ T1c), (2) marginal IR (MIR; GS 3 + 4, T2a-b), and (3) unfavourable IR (UIR; GS 4 + 3 or T2c). Biochemical relapse-free survival (BRFS), disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) were assessed. RESULTS A total of 1754 patients from the RECAP database were included and stratified by risk group: FIR, n = 781 (44.5%); MIR, n = 252 (14.4%); and UIR, n = 721 (41.1%). Mean age was 71 years (range 47-86). Mean PSA was 10.4 ng/ml (range 6-20). The median radiotherapy dose was 74 Gy, with mean doses of 72.5 Gy (FIR), 73.4 Gy (MIR), and 72.8 Gy (UIR). Most patients (88%) received ADT for a median of 7.1 months. By risk group (FIR, MIR, UIR), ADT rates were, respectively, 88.9, 86.5, and 86.9%. Only patients with ≥ 24 months of follow-up post-EBRT were included in the survival analysis (n = 1294). At a median follow-up of 52 months (range 24-173), respective 5- and 10-year outcomes were: OS 93.6% and 79%; BRFS 88.9% and 71.4%; DFS 96.1% and 89%; CSS 98.9% and 94.6%. Complication rates (≥ grade 3) were: acute genitourinary (GU) 2%; late GU 1%; acute gastrointestinal (GI) 2%; late GI 1%. There was no significant association between risk group and BRFS or OS. However, patients with favourable-risk disease had significantly better 5- and 10-year DFS than patients with UIR: 98.7% vs. 92.4% and 92% vs. 85.8% (p = 0.0005). CSS was significantly higher (p = 0.0057) in the FIR group at 5 (99.7% vs. 97.3%) and 10 years (96.1% vs. 93.4%). On the multivariate analyses, the following were significant predictors of survival: ADT (BRFS and DFS); dose ≥ 74 Gy (BRFS); age (OS). CONCLUSIONS This is the first nationwide study in Spain to report long-term outcomes of patients with intermediate-risk PCa treated with EBRT. Survival outcomes were good, with a low incidence of both acute and late toxicity. Patients with unfavourable risk characteristics had significantly lower 5- and 10-year disease-free survival rates. ADT and radiotherapy dose ≥ 74 Gy were both significant predictors of treatment outcomes.

Abstract
The purpose of this study is to evaluate the effects of neonatal thymectomy in the functional capacity of the immune system. We selected a group of 23 subjects, who had undergone thymectomy in their first 30 days of life, during an intervention for congenital heart disease. Several parameters of the immune system were evaluated during their first 3 years of life. Lymphocyte populations and subpopulations (including naive, memory and effector subpopulations), T cell receptor (TCR) Vbeta repertoire, response of T cells following in vitro stimulation by mitogen, quantification of immunoglobulins, TCR excision circles (TRECS) and interleukin (IL)-7 were measured. We found that neonatal thymectomy produces long-term diminution in total lymphocyte counts, especially in naive CD4+ and CD8+ T cells. Additionally, TRECS were decreased, and plasma IL-7 levels increased. A statistically significant negative correlation was found between absolute CD4+ T cells and IL-7 (r = -0.470, P = 0.02). The patients did not suffer more infectious events than healthy control children, but thymectomy in neonates resulted in a significant decrease in T lymphocyte levels and TRECS, consistent with cessation of thymopoiesis. This could produce a compromise in immune function later in life, especially if the patients suffer T cell depletion and need a reconstitution of immune function.

Abstract
We present two familial cases of complement factor 2 (C2) type I deficiency. Probands had experienced severe pyogenic bacteria infections in childhood and had undetectable levels of C2 and very low level of CH50. Both children were homozygous for the deletion of 28 bp in exon 6 of the C2 gene. Human leukocyte antigen (HLA) typing in family 1 had the commonly reported associations, but family 2 demonstrated a new association of the mutated C2 gene to HLA-A*3101, -Cw*0602, -B*1801, and -DRB1*0901. In addition, for the first time, the frequency of the 28-bp deletion of C2 and its HLA haplotypic associations have been analyzed in a sample of the Spanish population containing 790 haplotypes and 105 phenotypes. Cw*0602 is frequently found in Spanish haplotypes linked to the C2 mutated gene instead of the commonly reported -Cw*1203. The presence of heterozygous or homozygous individuals for the C2 deletion with low levels of IgD in both families supports the existence of a putative dominant susceptibility gene for IgD deficiency in haplotype HLA-B18, -S042, and -DR2. The frequency of the C2 28-bp deletion in heterozygosis is 1.4% (gene frequency 0.007) in Spanish healthy controls, similar to that reported in other white populations.

Abstract
The production, purification and stability of quality (in terms of integrity and glycosylation) of an antibody/interleukin-2 fusion protein with potential application in tumour-targeted therapy expressed in BHK21 cells are described. Consistency of the product throughout time was determined by analysis of glycosylation of the fusion protein using MALDI-TOF mass spectroscopy and HPAEC-PAD combined with product integrity studies by SDS-PAGE and Western blotting. These investigations showed consistent expression in terms of integrity and of three major oligosaccharide structures of the fusion protein after 62 generations. The data obtained at this stage indicated the suitability of the cell line for production purposes. Different approaches for the production of this protein were subsequently carried out. The relative productivity of the recombinant fusion protein and general performance of the cells in two different protein-free medium (PFM) culture systems, continuous chemostat and continuous perfusion using a Centritech centrifuge as a cell retention device, were studied. The results indicate that the chemostat culture resulted in more stable and controllable nutrient environment, which could indicate better product consistency, in accordance with what has been observed under serum-containing conditions, in relation to the perfusion culture. Finally, product obtained from the chemostat culture was analysed and purified. The purification process was optimised with an increase in the overall yield from 38 to 70% being obtained, a significant improvement with important consequences for the implementation of an industrial-scale culture system. In conclusion, it was possible to produce and purify the recombinant antibody/interleukin-2 fusion protein assuring the quality and stability of the product in terms of integrity and glycosylation. Therefore, a candidate production process was established.

Abstract
BACKGROUND Insufficiency fractures (IF) occur as a result of normal physiological stress on bones with deficient elastic resistance. Pelvic insufficiency fractures are a complication of osteoporosis due to postmenopausal status, high dose of corticosteroids, or local irradiation. They are important because differential diagnosis includes pelvic bone metastases. Diagnosis is based on both clinical manifestations and radiographic and scintigraphic findings. METHODS AND MATERIALS We examined eight patients with pelvic cancer who had previously undergone external beam radiation therapy as part of their treatment. In the follow-up, they developed insufficiency fractures, and no factor other than pelvic irradiation was present. Diagnosis was confirmed by radionuclide bone scan followed by conventional radiography and computed tomography (CT) scan. RESULTS The average onset of symptoms was 13.7 months after radiation therapy was completed. The initial symptom in all cases was pain. In all of the patients, the bone scan showed abnormalities. One to four increased uptake foci were observed, in the sacroiliac joint in all cases, and in the pubis in three cases. The initial diagnosis was bone metastases in five patients. CT scan showed fractures in all of the patients, in sacrum and pubis, both endostic and cortical. Treatment, consisting of nonsteroidal anti-inflammatory drugs and rest, led to symptomatic relief in all cases. CONCLUSION Knowledge of pelvic insufficiency fractures is essential in order to rule out metastasic disease, and thus avoid inaccurate treatment. Although radionuclide bone scan is useful in early detection of pelvic IF, definitive diagnosis is provided by CT scan.

Abstract
In this work the maximal operational hydrodynamic conditions (agitation and aeration rate) that cause no adverse effect in Sf-9 cells growth in SF900II serum-free medium were determined. Shear stresses higher than 1 N m-2 and aeration rates higher than 0.04 vvm affect cell growth and when these conditions increase to 1.5 N m-2 and 0.11 vvm, cell growth is completely inhibited with significant cell morphology changes and a strong decrease in viability. Although the pO2 did not show a significant effect upon cell growth in the range from 10 to 50%, cell infection and specific productivity were dramatically affected. The production was optimal at a pO2 of 25% with decreases higher than 50% being observed when the pO2 decreased to 10 or increased to 50%. The maximum product quality, i.e., the percentage of product in the form of high molecular weight particles, is not coincident with maximum product titer. Although the highest Pr55gag particle titer was obtained at 96 hours post infection (hpi) and at pO2 of 25%, the best product quality (defined by gel filtration chromatography and Western immunoblot) was obtained at 48 hpi, independently of the pO2 used. The effect of overcritical conditions upon productivity was also studied. As obtained for cell growth, cell infection is affected by shear stresses above 1 N m-2 and by aeration rates higher than 0.04 vvm, with decreases in Pr55gag particle titer higher than 70%, even when the overcritical values are still far from the limit at which cell death occurs. The results obtained and the optimization strategy used allowed the maximization of the oxygen supply without damaging the cells, with important consequences on the scale-up of a production process involving this insect cell/baculovirus expression system.

Abstract
BACKGROUND Equilibration of hemoglobin concentration after transfusion has been estimated to take about 24 hours, but some studies have shown that earlier measurements reflect steady-state values in persons who have not bled recently. This study was aimed at assessing the changes over time in hemoglobin concentration after transfusion in acutely anemic patients because of recent bleeding. STUDY DESIGN AND METHODS Thirty-two normovolemic patients recovering from an acute bleeding episode who were no longer thought to be bleeding and who received a 2-unit red cell transfusion were studied. At baseline and 15, 30, 60, and 120 minutes and 24 hours after transfusion, hemoglobin concentration and hematocrit values were measured. RESULTS The administration of 2 units of packed red cells elicited a 24-hour increase of 22.4 +/- 6.8 g per L in hemoglobin concentration. Hemoglobin values were not different at any of the defined posttransfusion times. Hematocrit levels experienced similar changes over time. Agreement between 15-minute and 24-hour values was excellent, as only 6 percent of patients exhibited a clinically significant difference (> 6 g/L) between the hemoglobin measurements. CONCLUSION Hemoglobin and hematocrit values rapidly equilibrate after transfusion in normovolemic patients who are recovering from an acute bleeding episode. This fact would allow a rapid assessment of the effects of transfusion and of the recurrence of bleeding in patients remaining at risk.

Abstract
To determine the effects of the 5-HT1A partial agonist tandospirone on acquisition and retention, mice were trained on a one-way active avoidance task and tested for retention 24 h later. Groups of mice were injected with either saline or 1, 5, or 10 mg/kg tandospirone 30 min before acquisition. Training was complete when animals achieved a criterion of five avoidances in a block of six trials. Results showed that tandospirone did not alter the rate of acquisition of the avoidance response, but retention was significantly disrupted by the 1- and 5-mg/kg doses. These findings confirm previous suggestions that 5-HT1A agonists can cause anterograde amnesia.

Abstract
A series of experiments was carried out to analyze the effects of the 5-HT1A agonists tandospirone or buspirone on the retention of fear conditioning in mice. Fear was produced by pairing tone and shock in a conditioned emotional response (CER) paradigm and strength of conditioning was assessed by measuring suppression of drinking in presence of tone. Fear conditioning was disrupted if tandospirone and buspirone were administered before the conditioning session but not before the test trial. Diazepam disrupted conditioning at both times. Tandospirone did not disrupt performance if conditioning was tested 1 hr rather than 24 hr after training, suggesting that disrupted memory rather than impaired acquisition was responsible for the deficit. The effect of tandospirone on fear conditioning could be reversed by administration of d-amphetamine prior to the retention test, which suggests that information was stored but is inaccessible to normal retrieval cues. Tandospirone and buspirone also retarded extinction, a clear indication that the disruption caused by these drugs is unrelated to their anxiolytic action.

Abstract
This report describes the chemotactic response of human alveolar macrophages (AM luminal diameter) and milk macrophages (MM luminal diameter) to a panel of chemotactic agents: endotoxin (EAS) and zymosan (ZAS) activated serum, lymphocyte derived chemotactic factor (LDCF) and formylated synthetic peptides. The locomotion studies were compared with the responses of peripheral blood monocytes. Both AM luminal diameter and MM luminal diameter exhibited an extremely poor chemotactic response to all agents in comparison with the monocytic response. When monocytes were cultured for long periods, a defective response was likewise demonstrated. The chemotactic response was significantly higher in AM luminal diameter from smokers. The stimulated locomotion was not increased by the addition of a surfactant lipoprotein to the AM luminal diameter suspension. Moreover, monocytes incubated with fat- and cell-free human milk exhibited lower chemotactic responses than normal monocytes and practically in the same range as that obtained with MM luminal diameter.

Abstract
A large population (about 80%) of the cells obtained from colostrum and early human milk were considered to be macrophages by the following criteria: nonspecific esterase stain, adherence, phagocytosis and IgG-Fc receptor expression. The majority of freshly isolated human milk macrophages (HMM phi) stain for the monocyte antigen OKM1. Another monocyte antigen, 61D3, was expressed only by 30% of HMM phi. Class II antigens were expressed by HMM phi. About 85% of the cells were DR-positive whereas 50% were DS-positive as assessed with a panel of monoclonal antibodies directed against class II antigens. Monocyte and class II antigens were gradually lost during in vitro culture. HMM phi can support proliferative response to antigens and mitogens when cocultured with autologous peripheral T cells. The proliferative response was significantly reduced when monoclonal antibodies to DR or DS were added to the assay. These results indicate that HMM phi have the phenotype and functional characteristics of antigen presenting cells.
