Abstract
Abstract
Introduction
Thirty patient advocates attended the First International Invasive Lobular Breast Cancer Symposium in 2016 at the University of Pittsburgh Cancer Center. The conference underscored that invasive lobular breast cancer (ILC) and other lobular pathologies are understudied. Specifically:
ILC is the sixth most prevalent cancer of women and the second most frequently diagnosed histological subtype of breast cancer impacting up to 34,000 patients a year in the US.
ILC is a molecularly distinct breast cancer with unique subtypes and variants with differences in presentation and behavior, including physical findings of thickening and a tendency to metastasize to unique locations.
While ILC is frequently associated with a good initial prognosis, recent analysis suggests that long-term outcomes of ILC may be worse than those stage-matched to ductal breast cancer.
Current imaging tools are less reliable for early detection of lobular disease and detection of distant recurrence.
Standard of care chemotherapy and endocrine therapies may have different effectiveness applied to ILC and IDC.
Challenges
Growing interest in ILC research requires improved methods to identify, communicate with and link patients with ILC to clinical trials and research. Advocates with advanced science training are needed as partners for research proposals and grant reviews.
Lobular breast cancer is under-represented in key meetings and literature. Encouraging opportunities to share ILC research as agenda topics and fostering collaborations between researchers, clinicians and advocates can accelerate progress and refine clinical practices for screening, treatment and follow-up.
Patients living with ILC lack a central on-line source of lobular breast cancer information and resources. This information gap is a barrier to help patients recognize signs of lobular breast cancer's unique presentation and metastatic behaviors.
Results
The Lobular Breast Cancer Alliance (LBCA) was formed by patient advocates who attended the First International ILC Symposium in response to advocate-identified opportunities to advance research, refine treatments and enhance patient education.
LBCA's mission is to bridge patients, clinicians and researchers to increase our knowledge of lobular breast disease and promote research that leads to advancements in prevention, diagnosis, treatment and patient follow-up care.
Conclusions
LBCA is driving an increased awareness of lobular breast cancer with specific goals:
Build a clinically accurate, patient centered website devoted to lobular breast cancer at www.LobularBreastCancer.org.
Elevate lobular research and foster opportunities for researcher, advocate and clinician collaborations at prominent conferences and meetings.
Identify barriers to conduct research on ILC and metastasis and link patients and advocates to ILC tumor research and clinical trials.
Initiate peer-to-peer clinician outreach strategy through targeted literature, meetings and education services to share information on ILC presentation, metastatic patterns and screening and treatment challenges of patients with ILC.
Build partnerships with existing breast cancer organizations to integrate ILC into existing information resources and work on common goals.

Abstract
Galactosemia type 1 is an autosomal recessive disorder of galactose metabolism, determined by a deficiency in the enzyme galactose-1-phosphate uridyltransferase (GALT). GALT deficiency is classified as severe or variant depending on biochemical phenotype, genotype and potential to develop acute and long-term complications. Neonatal symptoms usually resolve after galactose-restricted diet; however, some patients, despite the diet, can develop long-term complications, in particular when the GALT enzyme activity results absent or severely decreased. The mechanisms of acute and long-term complications are still discussed and several hypotheses are presented in the literature like enzymatic inhibition, osmotic stress, endoplasmic reticulum stress, oxidative stress, defects of glycosylation or epigenetic modification. This review summarizes the current knowledge of galactosemia, in particular the putative mechanisms of neonatal and long-term complications and the molecular genetics of GALT deficiency.

Abstract
Classical galactosemia is an autosomal recessive inborn error of metabolism due to mutations of the GALT gene leading to toxic accumulation of galactose and derived metabolites. With the benefit of early diagnosis by neonatal screening and early therapy, the acute presentation of classical galactosemia can be prevented. However, despite early diagnosis and treatment, the long term outcome for these patients is still unpredictable because they may go on to develop cognitive disability, speech problems, neurological and/or movement disorders and, in females, ovarian dysfunction. The objectives of the current study were to report our experience with a group of galactosemic patients identified through the neonatal screening programs in northeastern Italy during the last 30years. No neonatal deaths due to galactosemia complications occurred after the introduction of the neonatal screening program. However, despite the early diagnosis and dietary treatment, the patients with classical galactosemia showed one or more long-term complications. A total of 18 different variations in the GALT gene were found in the patient cohort: 12 missense, 2 frameshift, 1 nonsense, 1 deletion, 1 silent variation, and 1 intronic. Six (p.R33P, p.G83V, p.P244S, p.L267R, p.L267V, p.E271D) were new variations. The most common variation was p.Q188R (12 alleles, 31.5%), followed by p.K285N (6 alleles, 15.7%) and p.N314D (6 alleles, 15.7%). The other variations comprised 1 or 2 alleles. In the patients carrying a new mutation, the biochemical analysis of GALT activity in erythrocytes showed an activity of <1%. In silico analysis (SIFT, PolyPhen-2 and the computational analysis on the static protein structure) showed potentially damaging effects of the six new variations on the GALT protein, thus expanding the genetic spectrum of GALT variations in Italy. The study emphasizes the difficulty in establishing a genotype-phenotype correlation in classical galactosemia and underlines the importance of molecular diagnostic testing prior to making any treatment.

Abstract
Endocrine disruptor chemicals (EDCs), which are predominantly present in the environment, are able to mimic or antagonise the biological activity of hormones primarily through the interaction with specific receptors. The main consequences are adverse effects on the growth and development of reproductive organs, the induction of cancer and effects on neuronal differentiation. In this study, we investigated the ability of certain EDCs, Bisphenol A (BPA), Bisphenol B (BPB), Bisphenol F (BPF), 4-n Nonylphenol (NP) and Octylphenol (OP), belonging to a homogeneous group of phenol origin, to interfere with specific cellular processes, namely, proliferation, by using MCF-7 breast carcinoma cells, and differentiation, by using murine bone marrow dendritic cells. We correlated the data on cell growth with the stimulation of cell cycle progression, which could become a step in the development of cancer, and we established a proliferation ranking between the tested EDCs: NP>BPA>OP>BPB>BPF. In addition, we investigated the ability of NP, BPA and OP to induce the differentiation of dendritic cells, the powerful antigen-presenting cells of the immune system. The differentiation and activation of these cells could affect a well-regulated immune response and determine an allergic sensitisation. We found that BPA and NP were active in determining differentiation.

Abstract
Pregnant adult Balb-C mice were exposed daily to two different doses of Bisphenol A (BPA) by subcutaneous injection beginning on gestational day 1 through the seventh day after delivery. The mothers were sacrificed on postpartum day 21, and the offspring were sacrificed at 3 months of age. Control mice were subjected to the same experimental protocol but received saline injections. The liver, muscles, hindbrain and forebrain of the offspring were dissected and processed using HPLC to assess the level of BPA in the tissues and to determine its dependence on the exposure dose and gender. For comparison, the same tissues were dissected from the mothers and analysed. We report the following results: (1) the level of BPA that accumulated in a given tissue was dependent on the exposure dose; (2) the rank order of BPA accumulation in the various tissues was dependent on the gender of the offspring; (3) the average BPA concentrations in the liver and muscle of the female offspring were higher than in the males; and (4) the average BPA concentration in the central nervous system (i.e., the hindbrain and forebrain) of the male offspring was higher than in the females.

Abstract
Bisphenol A (BPA) is an endocrine disruptor (ED) that is abundant in the environment because of its extensive use in human-manufactured products. In this study, the BPA concentration was measured in the muscle and liver of five edible fish, characterized by different habitat and habits, caught in two different sites of the Tyrrhenian Sea (Italy). Our results show that: (i) fish livers are about 2.5 times more polluted than muscle; (ii) fish caught in the Gulf of Naples are more polluted than those from the Latium coasts, ranging from 1.2-fold more for White Bream to 6.6-fold for Grey Mullet; and (iii) the percentages of fish found to be BPA-polluted in the Gulf of Naples ranged from 73% (for Bass) to 90% (for Mullet), while the Latium fish range from 60% (for Bass) to 90% (for Mullet). These data indicate that consumers of fish caught in the Gulf of Naples are at a greater risk for BPA-induced endocrine pathologies compared to those who consume fish caught along the Latium coasts.

Abstract
Octylphenol (OP) is an endocrine-disrupting chemical that accumulates in various organs. It has also been shown to exert noxious effects on the central nervous system. In the present study, we measured in Sprague-Dawley rats the degree of OP accumulation in different areas of the brain and investigated the effect of OP in pain modulation. Two groups of male Sprague-Dawley rats were treated for 20 days with 50mg/kg BW/day of OP (group 1) or vehicle (group 2). At the end of the treatment, the formalin test was performed to evaluate the effect of OP exposure on pain. Soon after, rats were sacrificed, and the accumulation of OP in the cerebral cortex, hippocampus, hypothalamus, cerebellum, thalamus, striatum, mesencephalus and ventral hindbrain was measured by HPLC analysis. The results showed a greater accumulation of OP in the cerebral cortex compared to all the other areas; there was also more accumulation in the cerebellum compared to the mesencephalus and thalamus. No accumulation was found in the striatum. These results suggest that there is a preferential accumulation of OP in different areas of the brain with consequences to neural behaviour. On the contrary, experiments on facial grooming did not show significant effects of OP on pain.

Abstract
The aim of the present study was to evaluate the production of superoxide anion (O(2)(-)) in the trigeminal complex nuclei after a functional mechanical overload of the teeth due to the preference for masticating on one side in rats. The preference for masticating on one side was induced by the discomfort due to a small abrasion of one molar; such lateralisation in mastication was confirmed by electromyography. The production of O(2)(-) was evaluated in the trigeminal nuclei by fluorescence microscopy after an injection of dihydroethidium. The results showed that there was an increased production of O(2)(-) in the subnucleus oralis of the spinal trigeminal nucleus in the same side where the mastication was preferred. This result demonstrates that an increased activity of non-painful sensory neurons can enhance the production of reactive oxygen species within the central second order sensory nuclei.

Abstract
Serotonin receptors blockade is the major basis for the action of atypical antipsychotic drugs. Genetic factors affecting the density and/or function of serotonergic receptors, transporters and enzymes may therefore affect antipsychotic response. This exploratory study investigates the effect of ten polymorphisms from HTR1A, HTR1D, HTR2A, HTR3A, HTR3B, HTR4, HTR6, SLC6A4, TPH1, TPH2 genes on antipsychotic response in a sample of 289 patients with DSM-diagnosis of schizophrenia. Clinical Response was assessed using Brief Psychiatric Rating Scale (BPRS). Response was determined as 20% reduction improvement of BPRS compared to baseline. Selection of the biological relevant interactions, regardless the phenotype was performed using different statistics strategies regardless the phenotype to investigate epistasis within the serotonin system. the test for relevant interaction selection showed that 5HT4 and 5HT6 can be in epistatic relationship. the single locus analysis of these two receptor polymorphisms showed no significant results and the logistic regression model incorporating both genes, the clinical and demographic variables was not significant. Even this result is not significant, this strategy aimed to investigate the epistatic effect among genes could be useful for finding relevant biological interaction among genetic variants. Furthermore we are currently analyzing the methylation level of HTR2A in responders and non-responders, this epigenetic analysis will be very valuable in adding more information to the classic pharmacogenetic studies.

Other reactive oxygen species (ROS) such as hydrogen peroxide are able to modulate LTP and are likely to be involved in aging mechanisms. The present study explored whether intracerebro-ventricular (ICV) injection of oxidant or antioxidant molecules could affect LTP in vivo. With this aim in mind, field excitatory post-synaptic potentials (fEPSPs) elicited by stimulation of the perforant pathway were recorded in the dentate gyrus of the hippocampal formation in urethane-anesthetized rats. N-acetyl-L-cysteine, hydrogen peroxide (H2O2) or hypoxanthine/xanthine-oxidase solution (a superoxide producing system) were administrated by ICV injection. The control was represented by a group injected with saline ICV. Ten minutes after the injection, LTP was induced in the granule cells of the dentate gyrus by high frequency stimulation of the perforant pathway. Neither the H(2)O(2) injection or the N-acetyl-L-cysteine injection caused any variation in the fEPSP at the 10-min post-injection time point, whereas the superoxide generating system caused a significant increase in the fEPSP. Moreover, at 60 min after tetanic stimulation, all treatments attenuated LTP compared with the control group. These results show that ICV administration of oxidant or antioxidant molecules can modulate LTP in vivo in the dentate gyrus. Particularly, a superoxide producing system can induce potentiation of the synaptic response. Interestingly, ICV injection of oxidants or antioxidants prevented a full expression of LTP compared to the saline injection.

Abstract
This experiment tested the effect of a lesion of cerebral catecholaminergic neurons on the sympathetic and thermogenic effects induced by an intracerebroventicular (icv) injection of orexin A. The firing rates of the sympathetic nerves to the interscapular brown adipose tissue (IBAT), along with IBAT, colonic temperatures and heart rate were monitored in urethane-anesthetized male Sprague-Dawley rats before an injection of orexin A (1.5 nmol) into the lateral cerebral ventricle and over a period of 150 min after the injection. Three days before the experiment, the rats were pre-treated with an icv injection of 6-hydroxydopamine (6-OHDA) or 6-OHDA plus desipramine or saline. The results show that orexin A increases the sympathetic firing rate, IBAT, colonic temperatures and heart rate in the rats pre-treated with saline. This increase is blocked by the pre-treatment with 6-OHDA alone or 6-OHDA plus desipramine. These findings indicate that cerebral catecholaminergic neurons (particularly the dopaminergic pathway) play a fundamental role in the complex reactions related to activation of the orexinergic system.

Abstract
Since no experiment regarding a possible relation between quetiapine and orexin A has been reported in international literature, this experiment tested the effect of quetiapine on the sympathetic and thermogenic effects induced by orexin A. The firing rates of the sympathetic nerves to interscapular brown adipose tissue (IBAT), along with IBAT, colonic temperatures and heart rate were monitored in urethane-anesthetized male Sprague-Dawley rats before an injection of orexin A (1.5 nmol) into the lateral cerebral ventricle and over a period of 150 min after the injection. The same variables were monitored in rats with an intraperitoneal administration of quetiapine (5 or 10 mg/kg bw), injected 30 min before the orexin administration. The results show that orexin A increases the sympathetic firing rate, IBAT, colonic temperatures and heart rate. This increase is delayed or reduced by the injection of quetiapine. These findings indicate that quetiapine affects the complex reactions related to activation of orexinergic system. Possible influences on the control of body weight and temperature are discussed.

Abstract
This experiment tested the involvement of the ventromedial hypothalamus (VMH) in the sympathetic and hyperthermic reactions induced by an intracerebroventricular (i.c.v.) injection of orexin A (1.5 nmol). In the first part of the experiment, the firing rate and cytochrome oxidase activity of the VMH neurons, and the colonic temperature were monitored in 12 urethane-anaesthetized rats before an i.c.v. injection of orexin and over a period of 2 h after the injection. Orexin induced an increase in the firing rate, colonic temperature and cytochrome oxidase activity. A group of 12 rats was used as a control: saline, but not orexin, was injected. No modifications in the firing rate, cytochrome oxidase reactivity and colonic temperature were noted. In the second part of the experiment, 12 rats were anaesthetized and lesioned bilaterally in the VMH with an injection of ibotenic acid. Sham lesions were carried out in 12 control rats. After 48 h, all animals were anaesthetized with ethyl-urethane. The firing rates of the sympathetic nerves to interscapular brown adipose tissue (IBAT), along with IBAT and colonic temperatures and heart rate were monitored before and over a period of 2 h after an i.c.v. injection of orexin or saline in the lesioned and sham-lesioned rats. Orexin increased the sympathetic firing rate, IBAT and colonic temperatures and heart rate in the sham-lesioned rats. These increases were reduced by lesion of VMH. Saline did not induce any modification. These findings indicate that the VMH is involved in the control of the orexin-induced hyperthermia.

Abstract
This experiment tested the effect of risperidone on the sympathetic and thermogenic effects induced by orexin A. The firing rates of sympathetic nerves to interscapular brown adipose tissue (IBAT), along with IBAT and colon temperatures and heart rate were monitored in urethane-anesthetized male Sprague-Dawley rats before an injection of orexin A (1.5 nmol) into the lateral cerebral ventricle and over a period of 2 hours after the injection. The same variables were monitored in rats with an intraperitoneal administration of risperidone (50 mg/kg bw), injected 30 min before the orexin administration. The results show that orexin A increases the sympathetic firing rate, IBAT, colonic temperatures and heart rate. This increase is enhanced by the injection of risperidone. These findings suggest that risperidone elevates the responses due to orexin, probably through an involvement of serotoninergic and dopaminergic pathways, which are affected by risperidone. Furthermore, we suggested the name "hyperthermine A" as additional denomination of "orexin A" by considering the strong influence of this neuropeptide on body temperature.

Abstract
The in vivo survival of Kn(a+)McC(a+) red cells in a patient with anti- "Kna/McCa" was studied using 51Cr-labeled incompatible cells. The antibody was IgG4, demonstrable at 37 degrees C in the antiglobulin test, and did not bind complement. Survival of tagged cells was 82.2 percent after 24 hours. The patient was transfused with a total of 29 units of incompatible blood with no evidence of ill effects. The direct antiglobulin test became positive after transfusion and remained positive for 2 1/2 months of observation. The findings suggest that individuals with anti- "Kna/McCa" may be transfused with Kn(a+)McC(a+) red cells.

Abstract
A patient with pancytopenia and hypercellular bone marrow but without evidence of hemolysis had a positive direct antiglobulin test due to a red blood cell autoantibody. Although the patient was K-negative, eluates made from his erythrocytes contained what seemed to be anti-K antibody. The latter could be adsorbed onto and eluted from both K-positive and K-negative cells. We concluded that this patient is another example of autoanti-K antibody mimicking an alloanti-K antibody.
