Abstract
BACKGROUND Chemotherapy-induced damage of hematopoietic stem and progenitor cells (HSPC) causes multi-lineage myelosuppression. Trilaciclib is an intravenous CDK4/6 inhibitor in development to proactively preserve HSPC and immune system function during chemotherapy (myelopreservation). Preclinically, trilaciclib transiently maintains HSPC in G1 arrest and protects them from chemotherapy damage, leading to faster hematopoietic recovery and enhanced antitumor immunity. PATIENTS AND METHODS This was a phase Ib (open-label, dose-finding) and phase II (randomized, double-blind placebo-controlled) study of the safety, efficacy and PK of trilaciclib in combination with etoposide/carboplatin (E/P) therapy for treatment-naive extensive-stage small-cell lung cancer patients. Patients received trilaciclib or placebo before E/P on days 1-3 of each cycle. Select end points were prespecified to assess the effect of trilaciclib on myelosuppression and antitumor efficacy. RESULTS A total of 122 patients were enrolled, with 19 patients in part 1 and 75 patients in part 2 receiving study drug. Improvements were seen with trilaciclib in neutrophil, RBC (red blood cell) and lymphocyte measures. Safety on trilaciclib+E/P was improved with fewer ≥G3 adverse events (AEs) in trilaciclib (50%) versus placebo (83.8%), primarily due to less hematological toxicity. No trilaciclib-related ≥G3 AEs occurred. Antitumor efficacy assessment for trilaciclib versus placebo, respectively, showed: ORR (66.7% versus 56.8%, P = 0.3831); median PFS [6.2 versus 5.0 m; hazard ratio (HR) 0.71; P = 0.1695]; and OS (10.9 versus 10.6 m; HR 0.87; P = 0.6107). CONCLUSION Trilaciclib demonstrated an improvement in the patient's tolerability of chemotherapy as shown by myelopreservation across multiple hematopoietic lineages resulting in fewer supportive care interventions and dose reductions, improved safety profile, and no detriment to antitumor efficacy. These data demonstrate strong proof-of-concept for trilaciclib's myelopreservation benefits. CLINICAL TRAIL NUMBER NCT02499770.

Abstract
Pet cats may be used as a biomarker for assessing exposures to organohalogen compounds (OHCs) adsorbed to household dust in home environments. This study explores two exposure routes of OHCs, ingestion of OHCs (i) via house dust and (ii) via cat food. House dust from 17 Swedish homes and serum from the participating families' pet cats were collected, and cat food was purchased matching the diet reported. Paired samples of cat serum, house dust, and cat food were analyzed for brominated flame retardants/natural products (polybrominated diphenyl ethers (PBDEs), decabromobiphenyl (BB-209), decabromodiphenyl ethane (DBDPE), 2,4,6-tribromophenol (2,4,6-TBP), OH-PBDEs) and organochlorines (polychlorinated biphenyls (PCBs), 1,1-bis(4,4'-dichlorodiphenyl)-2,2,2-trichloroethane (4,4'-DDT), 1,1-bis(4,4'-dichlorodiphenyl)-2,2-dichloroethene (4,4'-DDE), hexachlorobenzene (HCB), pentachlorophenol (PCP)). Significant correlations were found between serum and dust samples from the living rooms for BDE-47 (p < 0.035), BDE-99 (p < 0.035), and BDE-153 (p < 0.039), from the adult's bedroom for BDE-99 (p < 0.019) and from all rooms for BDE-99 (p < 0.020) and BB-209 (p < 0.048). This is the first time a correlation between cat serum levels and household dust has been established, a finding that supports the hypothesis that dust is a significant exposure route for cats. Serum levels were also significantly correlated with concentrations found in cat food for 6-OH-BDE47 (p < 0.002), 2,4,6-TBP (p < 0.035), and BB-209 (p < 0.007). DBDPE was found in high concentrations in all dust (median 154 pmol/g) and food samples (median 0.7 pmol/g lw) but was below detection in serum samples, suggesting low or no bioavailability for DBDPE in cats.

Abstract
BACKGROUND There is concern that elders are not adequately evaluated prior to colon cancer surgery. We sought to determine adherence with ACOVE-3 (Assessing Care of Vulnerable Elders) quality indicators for pre-operative staging prior to colectomy for colon cancer utilizing the Surveillance, Epidemiology and End Results (SEER)-Medicare linked database (1992-2005). METHODS We determined the proportion of patients aged 75 and older who had preoperative staging prior to colectomy for colon adenocarcinoma. Preoperative staging was defined as abdominopelvic computed tomography or magnetic resonance imaging scan (SCAN) and colonoscopy or flexible sigmoidoscopy (SCOPE). Multivariate logistic regression identified predictors of adherence. Odds ratios were adjusted for comorbidity, socioeconomic status, and disease severity. The association of adherence to ACOVE-3 and survival was quantified. RESULTS Of the 37,862 patients, the majority were 75-84 years, 28% of the patients were ≥85 years. Regarding preoperative staging in the 6-month interval prior to surgical resection, 8% had neither SCAN nor SCOPE, 6% had only SCAN, 43% had only SCOPE, and 43% had both SCAN and SCOPE. Compared to patients who were not staged, those evaluated with either SCOPE alone or SCAN plus SCOPE had lower odds of 3-year mortality. Patients who were staged with SCAN alone had an increased odds of death compared to those who had neither SCAN or SCOPE. CONCLUSIONS These data demonstrate that the majority of vulnerable elders with colon cancer did not receive appropriate preoperative staging prior to resection. The findings also confirm that adherence to ACOVE-3 guidelines is associated with improved long-term survival.

Abstract
Dendritic cells (DC) are central in regulating skin immunity. Immunosenescence is associated with a chronic inflammatory state. Little is known about the contribution of DC to "inflamm-aging". When determining langerhans cell (LC) numbers, we found a 60 % reduction of LC in aged epidermis. Reactive oxygen species(ROS) are linked with aging. The mitochondrial manganese superoxide dismutase (SOD2) is in the first line of antioxidant defense. We investigated the function of DC from SOD2 heterozygous mice (SOD2+/-) and found that at 4 months of age LC numbers are not altered, but activated LC have impaired expression of MHC-II and CD44. Immature SOD2+/- DC produced increased proinflammatory IL-6 and chemokines CXCL1 and CXCL2. Upon challenge SOD2+/- DC accumulated ROS. When activating SOD2+/- DC by LPS they less efficiently upregulated MHC-II, CD86 and CD44. Surprisingly, in vivo contact hypersensitivity (CHS) was enhanced in SOD2+/- mice although SOD2+/- DC were less potent in stimulating wt T cells. However, SOD2+/- T cells showed increased proliferation, even when stimulated with SOD2+/- DC, possibly explaining the increased CHS. Our findings suggest that SOD2 is a molecular candidate in the regulation of "inflamm-aging" conveying both immunosuppressive and proinflammatory signals through alteration of DC and T cell functions.

Abstract
The hypothalamic decapeptide gonadotrophin-releasing hormone (GnRH) binds to specific receptors on pituitary gonadotrophs. These receptors belong to the family of G protein-coupled receptors. Their activation leads to phosphoinositide breakdown with generation of inositol 1,4,5-trisphosphate (Ins(1,4,5)P3) and diacylglycerol. These second messengers initiate Ca2+ release from intracellular stores and activation of protein kinase C, both of which are important for gonadotrophin secretion and synthesis. Prolonged activation of GnRH receptors by GnRH leads to desensitization and consequently to suppressed gonadotrophin secretion. This is the primary mechanism of action of agonistic GnRH analogues. By contrast, GnRH antagonists compete with GnRH for receptors on gonadotroph cell membranes, inhibit GnRH-induced signal transduction and consequently gonadotrophin secretion. These compounds are free of agonistic actions, which might be beneficial in certain clinical applications.

Abstract
The concern that antidepressant (AD) drugs, especially selective serotonin reuptake inhibitors and paroxetine (PAR) in particular, can increase suicidality during the early treatment of juvenile patients (children and adolescents) has created a dilemma for clinicians treating depressives. Although preclinical research cannot resolve controversy in this area, our present findings may provide insight into how AD drugs might, under certain conditions, exacerbate rather than ameliorate the depressive state. Both clinical and preclinical evidences indicate that the principal noradrenergic cell group in the brain, the locus coeruleus (LC), is overactive in depressives and that, conversely, effective AD treatments decrease the activity of LC neurons. We report here that short-term (2 and 4 days) administration of PAR produces an increase in the activity of LC neurons (spontaneous firing rate and sensory-evoked responses) in young rats, contrary to the 'therapeutic' decrease in activity typically observed in adult rats. Blood levels of PAR were lower in young rats than in adult rats, although similar low blood levels produced by a lower dose of PAR in adult rats failed to produce an increase in LC activity. In addition, activity of young rats in the swim test was determined to assess depressive-like responses. The same dose/durations of PAR, which produced the largest increases in LC activity in young rats, produced decreases in swim-test activity, indicating that brief administration of PAR in young rats can promote, rather than reduce, the depressive state. These results offer a model that may help screen potential adjunctive treatments to avoid early adverse effects of ADs.

Abstract
Cryopreservation as a process can be divided into two methods: conventional freezing and vitrification. The high effectiveness of vitrification in comparison with conventional freezing for human oocytes and embryos is shown, whereas data on human ovarian tissue are limited. The aim of this study was to compare the safety and effectiveness of conventional freezing and vitrification of human ovarian tissue. Ovarian tissue fragments from 15 patients were transported to the laboratory within 22–25 h in a special, isolated transport box that can maintain a stable temperature of between 5 and 8 °C for 36 h. Small pieces of ovarian tissue (0.3–1×1–1.5×0.7–1 mm) were randomly distributed into three groups: group 1, fresh pieces immediately after receiving transport box (control); group 2, pieces after vitrification; and group 3, pieces after conventional freezing. After thawing, all the pieces were culturedin vitro. The viability and proliferative capacity of the tissue byin vitroproduction of hormones, development of follicles, and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene expression after culture were evaluated. A difference between freezing and vitrification was not found in respect to hormonal activity and follicle quality. The supernatants showed 17-β estradiol concentrations of 365, 285, and 300 pg/ml respectively, and progesterone concentrations of 3.82, 1.99, and 1.95 ng/ml respectively. It was detected that 95, 80, and 83% follicles respectively were morphologically normal. The molecular biological analysis, however, demonstrated that theGAPDHgene expression in ovarian tissue after vitrification was dramatically decreased in contrast to conventional freezing. For cryopreservation of human ovarian tissue, conventional freezing is more promising than vitrification, because of higher developmental potential.

Abstract
This study investigates the ability of sucrose to protect spermatozoa against mitochondrial damage, artificial cryoinduction of capacitation, and acrosome reaction. Spermatozoa were isolated using the swim-up procedure performed using three different media: (a) human tubal fluid (HTF, control) medium; (b) HTF with 1% human serum albumin (HSA); and (c) HTF with 1% HSA and 0.25 M sucrose. From each group, 30 mul suspensions of cells were dropped directly into liquid nitrogen and stored for at least 24 h. Cells were thawed by quickly submerging the spheres in HTF with 1% HSA at 37 degrees C with gentle agitation. Sperm motility, viability, mitochondrial membrane potential integrity, spontaneous capacitation, and acrosome reaction were investigated. Sperm viability, acrosome reaction, and capacitation were detected using the double fluorescence chlortetracycline-Hoechst 33258 staining technique. Mitochondrial function was evaluated using a unique fluorescent cationic dye, 5,5',6,6'-tetrachloro-1-1',3,3'-tetraethyl-benzamidazolocarbocyanin iodide, commonly known as JC-1. The number of progressively motile spermatozoa was significantly higher in the sucrose-supplemented medium group (57.1+/-3.2%, P<0.05) when compared with controls (19.4+/-1.9%). The combination of HSA and sucrose (65.2+/-2.6%) has a stronger cryoprotective effect on the integrity of mitochondrial membrane potential (P<0.05) compared with HSA alone (32.6+/-4.7%). In conclusion, vitrification of human spermatozoa with non-permeable cryoprotectants such as HSA and sucrose can effectively cryopreserve the cells without significant loss of important physiological parameters.

Abstract
Several lines of rats potentially useful for studying affective disorders have been developed in our laboratory though selective breeding for behavioral characteristics. The propensity of these lines to consume alcohol and other drugs of abuse (amphetamine and cocaine) was examined. Also, measurement of the concentration of brain monoamines - norepinephrine, dopamine, and serotonin - as well as estimation of their metabolism by measurement of the major extracellular metabolites of these monoamines was carried out to examine possible relationships of brain chemistry to the behavioral characteristics shown by these lines, as well as to their propensity for drug usage. The lines of rats are: Swim Low-active (SwLo) and Swim High-active (SwHi), which show either very low (SwLo) or very high (SwHi) amounts of motor activity in a swim test; Swim-test Susceptible (Susceptible or SUS) and Swim-test Resistant (Resistant or RES), which are highly susceptible (SUS) or highly resistant (RES) to having their swim-test activity depressed by being exposed to a stressful condition prior to the swim test; and Hyperactive (HYPER), which show spontaneous nocturnal hyperactivity compared to non-selectively bred (i.e., normal) rats as well as both extreme hyperactivity and behavioral depression after being exposed to a stressful condition. Regarding alcohol and drug usage, SUS rats readily consume alcohol while all other lines including non-selected, normal rats do not, and SwLo rats show a strong tendency to consume amphetamine and cocaine. Marked differences in brain monoamines were found between the various lines and normal rats, with salient differences seen in norepinephrine, particularly in the hippocampus, and in dopamine in forebrain regions (striatum and nucleus accumbens).

Abstract
When rats are exposed to highly stressful events over which they have no control, they subsequently show many of the symptoms seen in depression in humans. In the attempt to discover neurochemical factors underlying depression, the neurochemical basis of stress-induced behavioural depression in rats has been studied extensively. Initial research (1968-1976) indicated that behavioural depression in this model was produced by alteration of noradrenaline (NA) concentrations in the brain. More recent research has indicated that the critical change may be a large depletion of NA in the locus ceruleus (LC). Behavioural depression may result when such NA depletion is sufficient to reduce NA release in the LC region, leading to a 'functional blockade' of inhibitory alpha 2-receptors in that brain region. Studies have now shown that behavioural depression after uncontrollable shock can be mimicked by pharmacological blockade of alpha 2-receptors in the LC region. Conversely, behavioural depression can be eliminated by either infusion of clonidine into the LC to replace at the alpha 2-receptors the NA depleted after uncontrollable shock, or infusion of pargyline into the LC to prevent the depletion of NA that otherwise follows uncontrollable shock. If alpha 2-receptors are functionally blocked in depression, then release of NA in regions innervated by the LC should be increased and stimulation of postsynaptic adrenoceptors outside the LC should be higher than normal. Thus, higher-than-normal stimulation of postsynaptic NA receptors should also produce behavioural depression; this has been demonstrated.

Abstract
We report on a patient with AIDS stage C3, who received haemodialysis for terminal renal insufficiency and presented with Kaposi sarcoma-like skin lesions on the left hand, distal of his dialysis shunt. Histology, immunohistochemistry and PCR analysis did not support the initially favoured diagnosis of a Kaposi sarcoma, but revealed a pseudo-Kaposi sarcoma related to the Stewart-Bluefarb-syndrome.

Abstract
BACKGROUND Insulin resistance and obesity play an important role in the pathogenesis of polycystic ovary syndrome (PCOS). It is known that experimentally induced insulin resistance diminishes the stimulatory effect of insulin on leptin secretion. It is not yet known whether the long-term insulin resistance as found in PCOS patients alters the leptin response to hypo- and hyperglycaemia. METHODS We induced hyper- and hypoglycaemia by glucose clamp technique in 7 patients with PCOS and 20 healthy controls. After a plasma glucose level of 8.8 mmol/l was reached, the plasma glucose level was reduced stepwise to 6.8, 4.8 and 2.8 mmol/l. RESULTS The PCOS patients required lower glucose infusion rates to reach the glycaemic targets (P < 0.05). Serum insulin and C-peptide concentrations increased significantly during the clamp compared with the baseline in both groups (P < 0.001 for insulin, and P < 0.001, P < 0.005 for C-peptide control and PCOS, respectively) and increased significantly more in PCOS patients compared with the control group (both P < 0.05). Basal leptin levels were significantly higher in the PCOS group than in the control group (P = 0.005). In the controls, the leptin concentration increased significantly during the clamp (P < 0.001 for each glycaemic target), whereas in the PCOS group, leptin secretion increased only during hypoglycaemia (P = 0.04). CONCLUSIONS Compared with the healthy controls, the response of leptin secretion to hyper- and hypoglycaemia was diminished in PCOS patients. Changes in leptin secretion seem not to be caused by hyper- and hypoglycaemia, but rather by hyperinsulinaemia. Reduced insulin sensitivity seems to be responsible for the diminished leptin response, which might contribute to the obesity found in PCOS patients.

Abstract
Interactions between CD40 and CD40 ligand (CD154) are essential in the regulation of both humoral and cellular immune responses. Forced expression of human CD154 in B chronic lymphocytic leukemia (B-CLL) cells can upregulate costimulatory and adhesion molecules and restore antigen-presenting capacity. Unfortunately, B-CLL cells are resistant to direct gene manipulation with most currently available gene transfer systems. In this report, we describe the use of a nonviral, clinical-grade, electroporation-based gene delivery system and a standard plasmid carrying CD154 cDNA, which achieved efficient (64+/-15%) and rapid (within 3 h) transfection of primary B-CLL cells. Consistent results were obtained from multiple human donors. Transfection of CD154 was functional in that it led to upregulated expression of CD80, CD86, ICAM-I and MHC class II (HLA-DR) on the B-CLL cells and induction of allogeneic immune responses in MLR assays. Furthermore, sustained transgene expression was demonstrated in long-term cryopreserved transfected cells. This simple and rapid gene delivery technology has been validated under the current Good Manufacturing Practice conditions, and multiple doses of CD154-expressing cells were prepared for CLL patients from one DNA transfection. Vaccination strategies using autologous tumor cells manipulated ex vivo for patients with B-CLL and perhaps with other hematopoietic malignancies could be practically implemented using this rapid and efficient nonviral gene delivery system.

Abstract
The secretion of luteinizing hormone (LH) and the GnRH receptor (GnRH-R) concentration are modulated by ovarian steroids and GnRH. To elucidate whether this regulation is due to alterations at the transcriptional level, we examined the GnRH I-R mRNA expression in the gonadotroph-derived cell line alphaT3-1 treated with different estradiol and progesterone paradigms and the GnRH I agonist triptorelin. alphaT3-1 cells were treated with different steroid paradigms: 1 nM estradiol or 100 nM progesterone for 48 h alone or in combination. Cells were exposed to 10 nM or 100 pM triptorelin for 30 min, 3 h, 9 h, or, in pulsatile way, with a 5-min pulse per hour. The GnRH I-R mRNA was determined by Northern blot analysis. GnRH I-R mRNA from cells treated with continuous triptorelin decreased in a time- and concentration-dependent manner. Pulsatile triptorelin increased GnRH I-R gene expression. Progesterone alone further enhanced this effect, whereas estradiol and its combination with progesterone diminished it. Continuous combined treatment with estradiol and progesterone lead to a significant decrease of GnRH I-R mRNA by 30% and by 35% for estradiol alone. The addition of 10 nM triptorelin for 30 min or 3 h could not influence that steroid effect. In conclusion, estradiol and progesterone exclusively decreased GnRH I-R mRNA in alphaT3-1 cells no matter whether they are treated additionally with the GnRH I agonist triptorelin. The enhanced sensitivity of gonadotrophs and GnRH I-R upregulation by estradiol is not due to increased GnRH I gene expression because GnRH I-R mRNA is downregulated by estradiol and progesterone. Other pathways of the GnRH I-R signal transduction might be involved.

Abstract
RATIONALE AND OBJECTIVE This paper describes a new procedure for detecting effective antidepressant treatments. The procedure uses the swim-test susceptible (Susceptible) rat which has been selectively bred to show decreased struggling behavior in a swim test after exposure to a mild stressor. The ability of treatments to block this decrease in swim-test activity was assessed as a method for detecting effective antidepressants. RESULTS In both male and female Susceptible rats, chronic (14-day) treatment with different antidepressant drugs delivered via osmotic minipump [i.e., three tricyclics (desmethylimipramine, imipramine, amitriptyline), two selective serotonin reuptake inhibitors (fluoxetine and sertraline), a monoamine oxidase inhibitor (phenelzine), and two atypical antidepressants (venlafaxine and bupropion)] all prevented the stress-induced decrease in swim-test struggling normally shown by these rats. Electroconvulsive shock had a similar effect. Unlike antidepressant drugs, 14-day treatment with various non-antidepressant drugs [i.e., a stimulant (amphetamine), an anxiolytic (chlordiazepoxide), an antihistamine (chlorpheniramine), and an anticholinergic (scopolamine)] did not have this effect. Antidepressant drug treatment for 1 day (i.e., acute treatment) was also ineffective in this test. The procedure described above requires use of the Susceptible rat--swim test resistant rats (i.e., rats selectively bred to be resistant to decreased swim-test activity after exposure to stressful conditions) showed no significant differences in swim-test behavior between stress and nonstress conditions after 14-day drug treatment, and randomly bred Sprague-Dawley rats did not show a decrease in swim-test activity following exposure to the mild stressor that is the basis for the test. CONCLUSION These results suggest that the procedure described here, which uses a rat subject that has been bred for vulnerability to stressful conditions, may be a selective screening technique for effective antidepressant treatments.

Abstract
Our earlier studies demonstrated that representative microbial substances--lipopolysaccharide, peptidoglycan, and poly-inosine: poly-cytosine (poly(I):(C))--increased the spontaneous discharge rates and sensory-evoked responses of isolated locus coeruleus (LC) neurons in a dose- and time-related manner after i.p. injection into rats. We then turned our attention to the mechanism by which microbial substances administered into the peritoneal cavity affect the LC neurons. The involvement of the subdiaphragmatic vagus nerves was examined in this regard since several brain responses to peripherally administered lipopolysaccharide have been found to depend upon the integrity of these nerves. The experiments reported here show that lipopolysaccharide, peptidoglycan, and poly(I):(C) all failed to excite LC neurons after i.p. injection into rats that had previously been subjected to complete transection of the subdiaphragmatic vagus nerves. Furthermore, selective transection of the subdiaphragmatic vagus nerve trunks indicated that the dorsal trunk, and not the ventral trunk, was necessary to excite LC neurons in response to i.p. lipopolysaccharide. The inability of LC neurons to respond to i.p. lipopolysaccharide in vagotomized rats is unlikely to be attributed to a desensitization of the neurons to lipopolysaccharide since i.c.v. injection of lipopolysaccharide excited LC neurons in vagotomized rats as it did in vagus-intact rats. These findings suggest that a variety of microbial substances excited LC neurons after administration into the peritoneal cavity in a manner involving the subdiaphragmatic vagus nerves.

Abstract
The gene encoding human 8-oxoguanine glycosylase 1 (hOGG1) is involved in DNA base excision repair. The encoded DNA glycosylase excises 7,8-dihydro-8-oxoguanine (8-OHdG), a highly mutagenic base produced in DNA as a result of exposure to reactive oxygen species (ROS). Polymorphisms in this gene may alter glycosylase function and an individual's ability to repair damaged DNA, possibly resulting in genetic instability that can foster carcinogenesis. In order to elucidate the possible impact of polymorphisms in hOGG1, we performed a literature review of both functional and epidemiologic studies that assessed the effects of these polymorphisms on repair function, levels of oxidative DNA damage, or associations with cancer risk. Fourteen functional studies and 19 epidemiologic studies of breast, colon, esophageal, head and neck, lung, nasopharyngeal, orolaryngeal, prostate, squamous cell carcinoma of the head and neck (SCCHN), and stomach cancers were identified. Although the larger functional studies suggest reduced repair function with variant alleles in hOGG1, the evidence is generally inconclusive. There is some epidemiologic evidence that risk for esophageal, lung, nasopharyngeal, orolaryngeal, and prostate is related to hOGG1 genotype, whereas risk of breast cancer does not appear related. In studies that explored potential interactions with environmental factors, cancer risk for hOGG1 genotypes differed depending on exposure, especially for colon cancer. In summary, there is limited evidence that polymorphisms in hOGG1 affect repair function and carcinogenesis. Larger, well-designed functional and epidemiologic studies are needed to clarify these relationships, especially with respect to interactions with other DNA repair enzymes and interactions with environmental factors that increase carcinogenic load.

Abstract
The polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age. It is a complex metabolic-endocrine disorder with severe long-term health consequences like type 2 diabetes. The increased risk for cardiovascular diseases in women with PCOS is due to diabetes, adipositas and dyslipidemia. Insulin resistance plays a key role in the pathophysiology of this syndrome. This makes the use of oral antidiabetic drugs most compelling. The majority of studies have shown amelioration of the typical symptoms like hyperandrogenism and cycle irregularities. Ovulation and pregnancy rates increased. Furthermore these drugs might be cardioprotective by improving insulin sensitivity and reduce the risk for type 2 diabetes. This article reviews the use of different oral antidiabetic drugs in the treatment of PCOS and their influence on fertility, the risk for type 2 diabetes and cardiovascular diseases.

Abstract
Common ivy (Hedera helix L.) is a ubiquitous plant in Europe whose major allergen falcarinol has moderate allergic potential. It is not related to poison ivy (Toxicodendron spp.). There are no cross reactions between the allergens of common ivy (falcarinol) and poison ivy (urushiol). Contact with common ivy or falcarinol may lead to sensitization and then a delayed hypersensitivity reaction. There are only few cases described in the literature. We report on a male hobby gardener with appropriate clinical history and positive patch test. The pathogenic mechanism is a type IV reaction following a sensitization exposure. Gardeners and landscape architects with frequent exposure to common ivy and thus a high risk of sensitization should wear appropriate protective clothing.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is associated with insulin resistance and hyperinsulinemia, which might contribute to the hypersecretion of luteinizing hormone (LH). Hyperprolactinemia is another finding in a subgroup of patients with PCOS, whereas its relation to hyperinsulinemia is not fully understood yet. METHODS In the present study we tested the hypothesis that insulin might affect LH or prolactin secretion of cultured female rat pituitary cells. To address the mechanisms by which insulin could act at the intracellular level we examined the GnRH- and TRH-induced Ca(2+) signals in single gonadotrophs and lactotrophs, because Ca(2+) is an important component of GnRH signal transduction that is closely related to exocytosis. RESULTS Cells treated for 24 h with insulin (10(-9) M) showed an enhancement of basal and agonist-induced LH and prolactin secretion. Insulin did not affect GnRH- and TRH-induced Ca(2+) signals compared to controls. There were no differences neither in the frequency nor in the amplitude of the Ca signal. CONCLUSION Our findings suggest that insulin might contribute to LH hypersecretion. Insulin might be partially responsible for hyperprolactinemia. Since insulin did not affect Ca signaling, other components of the GnRH signal transduction pathway might be involved in LH hypersecretion.

Abstract
OBJECTIVE Recently, GnRH antagonists (GnRHants) have been introduced for the prevention of premature LH surges during controlled ovarian hyperstimulation (COH). Here we investigated whether the GnRHants cetrorelix and ganirelix exert effects on the human ovarian IGF system. Since controversy exists on the action of GnRH agonists in the human ovary, we also tested the effect of triptorelin on IGF-II, IGF-binding protein-2 (IGFBP-2) and pregnancy-associated plasma protein-A (PAPP-A) in cultured human granulosa-lutein cells. DESIGN In vitro cell culture study in a research laboratory of a university hospital. PATIENTS Cells were obtained from patients treated with different protocols of COH. In addition to gonadotropins they received triptorelin or cetrorelix. Cells were treated with triptorelin, cetrorelix or ganirelix, 1 nmol/l each, for 48 h. IGF-II, IGFBP-2 and PAPP-A were measured by RIA and enzyme immunoassay respectively. RESULTS GnRHants and triptorelin did not affect IGF-II, IGFBP-2 or PAPP-A. CONCLUSIONS We conclude that GnRHants do not exert any significant effects on the IGF system of granulosa-lutein cells and therefore their introduction into protocols of COH is unlikely to impair ovarian function.

Abstract
Insulin-like growth factors are involved in the regulation of gonadotropin secretion. Insulin-like growth factor I (IGF-I) has an augmenting effect on gonodotropin-releasing hormone (GnRH)-induced luteinizing hormone (LH) release from female rat gonadotrophs that is facilitated by estradiol. To identify the underlying mechanisms, we investigated whether IGF-I influences total LH pool and the production of intracellular inositol phosphate. In another series of experiments we tested whether IGF-II and estradiol affect LH release of gonadotrophs. Pituitary cells were incubated with 100 pM IGF-I and/or 100 pM estradiol for 24 h. They were stimulated, partially in the presence of Wortmannin, an inhibitor of phosphoinositide 3-kinase, with 330 pM GnRH for 3 h. Subsequently, total LH pool (released and remaining hormone content in lysed cells) in cultures was measured. Intracellular inositol trisphosphate of alphaT3-1 cells, a gonadotrope cell line, treated with estradiol and IGF-I as described before and stimulated with 100 nM GnRH for 15 min was analyzed by ion exchange chromatography. To determine the interaction of IGF-II and estradiol on GnRH-stimulated LH secretion, cells were treated with increasing concentrations of IGF-II (0.05 pM-10 nM) and 100 pM estradiol. IGF-I significantly increased the accumulation of inositol trisphosphate in basal and GnRH-stimulated cells. IGF-I, estradiol, or their combinations did not change total LH pool, although they enhanced LH secretion. Wortmannin abolished the positive effects of IGF-I and estradiol on LH secretion. IGF-II alone increased basal, but not GnRH-induced LH secretion at low concentrations (0.05 pM). Additional estradiol treatment further increased basal, but not GnRH-induced LH secretion. In conclusion, our results suggest that increased LH secretion from female anterior pituitary cells after IGF treatment is due to the amplification of early signal transduction steps rather than changes in LH pool. The inositol trisphosphate signaling pathway is involved in the regulation of LH secretion from gonadotrophs treated with IGF-I. It is not likely that IGF-II plays an important role in the regulation of gonadotropin secretion.

Abstract
The German Embryo Protection Law permits only the cryopreservation of supernumerary pronuclear stage eggs. Data are needed to counsel patients about their individual benefits from this procedure. All fresh embryo transfer cycles performed from January 1994 until December 1998 in which supernumerary pronucleate eggs were cryopreserved (n = 557) were analysed retrospectively, together with data from all subsequent cycles involving transfers of frozen-thawed pronucleate eggs (n = 420) from January 1994 until June 2001. The additional cumulative pregnancy rate per fresh cycle was 11.5%. This rate depended on the number of embryos per transfer, i.e. 1.9, 8.2 and 13.0% respectively when one, two or three embryos were transferred (P < 0.05). A strong correlation was found between the numbers of cryopreserved pronucleate eggs and pregnancy rates, of 9.3, 10.5 and 17.1% when 1-3, 4-6, or at least 7 pronucleate eggs were available respectively. Additional benefit in terms of this rate from cryopreservation for a patient with and without a pregnancy in the fresh embryo transfer cycles was 5.3 and 12.7% respectively. It is concluded that higher pregnancy rates in cycles involving cryopreserved eggs for patients who did not become pregnant in fresh transfer cycles reveals the disadvantage of the German Embryo Protection Law, which does not allow embryo selection. Therefore, cryopreservation of pronucleate eggs with a higher developmental potential is possible. The total pregnancy rate could be raised from 28.0 to 35.5% per fresh transfer cycle.

Abstract
INTRODUCTION This study was performed to evaluate whether a tailored approach to the administration of the GnRH antagonist cetrorelix acetate according to follicular size leads to a reduction in the amount of Cetrotide vials used and/or an increased number of monitoring visits. METHODS Sixty patients were prospectively randomized (using sealed envelopes) to receive either the fixed multiple dose antagonist protocol starting on day 6 of stimulation (group 1), or an individualized protocol with the time of antagonist start according to follicle size (14 mm, group 2), or an individualized single dose protocol (group 3). Recombinant human (rh)FSH was used. The primary endpoints were the number of Cetrotide vials and number of monitoring visits. Statistical power for the parameter Cetrotide vials was 80%. RESULTS Patients in group 1 needed significantly more Cetrotide vials (6.81 +/- 1.61) than patients of group 2 (4.59 +/- 1.65; P < 0.01). The number of monitoring visits was similar between the three groups. Surprisingly, the number of retrieved oocytes was significantly higher in the individualized groups as compared with group 1. Despite a significantly lower total amount of rhFSH used, estradiol levels were significantly higher in group 2 as compared with group 1. CONCLUSION Tailoring of GnRH antagonist protocols leads to an optimization of ovarian stimulation with more oocytes retrieved despite less rhFSH used, and the same number of monitoring visits.

Abstract
Supernumary pronucleated stage oocytes (PN) can be cryopreserved and later transferred in spontaneous, stimulated or artificial cycles. In this study, we re-evaluated 342 artificial cycles with a transdermal estradiol release system (Estraderm TTS 100) in combination with a vaginal progesterone delivery system (Crinone 8%). Endometrial thickness and serum estradiol on day 14 were correlated with clinical and ongoing pregnancy rates. Endometrial thickness between 7 and 15 mm did not relate to significantly different pregnancy rates. The estradiol serum level did not predict success. In conclusion, this method of endometrial preparation is comfortable for patients and monitoring is unnecessary.

Abstract
The Crinone 8% preparation makes it possible to administer natural progesterone (90 mg) vaginally once daily for luteal phase support (LPS). Until now, no prospective, randomized studies have directly compared this new preparation with widely used Utrogest capsules, which were originally designed for oral administration but are used routinely as a vaginal preparation. A prospective, randomized study investigated 126 patients undergoing cycles of in vitro fertilization (IVF) and IVF/intracytoplasmic sperm injection (ICSI). Patients received either Crinone 8% (n = 73) vaginally once daily or two Utrogest capsules (n=53) vaginally three times daily (600 mg). Clinical pregnancy rates were comparable (28.8 versus 18.9%), as were clinical abortion rates until 12 weeks of gestation (14.3 versus 10.0%) and clinical ongoing pregnancy rates (24.7 versus 17.0%) in the Crinone 8% and Utrogest groups, respectively. Forty-seven non-pregnant patients were randomly selected to answer questions regarding comfort during LPS. Crinone 8% had a clear advantage over Utrogest as it resulted in less vaginal discharge (P < 0.01) and fewer application difficulties (P<0.05). Twenty patients familiar with the alternative preparation from a previous cycle also noted that Crinone 8% was easier to apply (P < 0.01) and less time consuming (P < 0.05) to use than Utrogest.
