Abstract
TP63-related disdorders broadly involve varying combinations of ectodermal dysplasia (sparse hair, hypohydrosis, tooth abnormalities, nail dysplasia), cleft lip/palate, acromelic malformation, split-hand/foot malformation/syndactyly, ankyloblepharon filiforme adnatum, lacrimal duct obstruction, hypopigmentation, and hypoplastic breasts and/or nipples. TP63-related disorders are associated with heterozygous pathogenic variants in TP63 and include seven overlapping phenotypes; Ankyloblepharon-ectodermal defects-cleft lip/palate syndrome (AEC), Ectrodactyly-ectodermal dysplasia-cleft lip/palate syndrome 3 (EEC3), Limb-mammary syndrome (LMS), Acro-dermo-ungual-lacrimal-tooth syndrome (ADULT), Rapp-Hodgkin syndrome (RHS), Split-hand/foot malformation 4 (SHFM4), and Orofacial cleft 8. We report on five unrelated families with 8 affected individuals in which the probands presented with varying combinations of ectodermal dysplasia, cleft lip/palate, split-hand/foot malformation, lacrimal duct obstruction, and ankyloblepharon filiforme adnatum. The clinical diagnosis involved AEC syndrome (2 patients), EEC3 syndrome (2 patients), and a yet hitherto unclassified TP63-related disorder. Sanger sequence analysis of the TP63 gene was performed revealing five different variants among which four were novel and three were de novo. The identificated TP63 variants co-segregated with the other affected individuals in the families. The abnormalities of ectoderm derived structures including hair, nails, sweat glands, and teeth should alert the physician to the possibility of TP63-related disorders particularly in the presence of orofacial clefting.

Abstract
Enteroendocrine cells (EECs) constitute only a small proportion of Villin-1 (Vil1)-expressing intestinal epithelial cells (IECs) of the gastrointestinal tract; yet, in sum, they build the largest endocrine organ of the body, with each of them storing and releasing a distinct set of peptides for the control of feeding behavior, glucose metabolism, and gastrointestinal motility. Like all IEC types, EECs are continuously renewed from intestinal stem cells in the crypt base and terminally differentiate into mature subtypes while moving up the crypt-villus axis. Interestingly, EECs adjust their hormonal secretion according to their migration state as EECs receive altering differentiation signals along the crypt-villus axis and thus undergo functional readaptation. Cell-specific targeting of mature EEC subtypes by specific promoters is challenging because the expression of EEC-derived peptides and their precursors is not limited to EECs but are also found in other organs, such as the brain (e.g., Cck and Sst) as well as in the pancreas (e.g., Sst and Gcg). Here, we describe an intersectional genetic approach that enables cell type-specific targeting of functionally distinct EEC subtypes by combining a newly generated Dre-recombinase expressing mouse line (Vil1-2A-DD-Dre) with multiple existing Cre-recombinase mice and mouse strains with rox and loxP sites flanked stop cassettes for transgene expression. We found that transgene expression in triple-transgenic mice is highly specific in I but not D and L cells in the terminal villi of the small intestine. The targeting of EECs only in terminal villi is due to the integration of a defective 2A separating peptide that, combined with low EEC intrinsic Vil1 expression, restricts our Vil1-2A-DD-Dre mouse line and the intersectional genetic approach described here only applicable for the investigation of mature EEC subpopulations.

Abstract
OBJECTIVE Prenatal diagnosis of the Ectrodactyly-Ectodermal dysplasia-clefting (EEC) syndrome has been based upon the detection of ectrodactyly, in association with facial clefting and/or positive family history. Our aim is to describe other ultrasonographic features indicating the presuntive diagnosis, regardless of genetic diagnosis, especially in cases of negative family history. MATERIALS AND METHODS A case report and a review of the literature was assessed. RESULTS Our case report showed a singleton foetus "lobster claw" deformities of hands and feet. Paternal history revealed bilateral agenesia of two fingers. Through literature, 15 case reports of prenatal diagnosis of EEC syndrome were found, 14 of which were eligible for our systematic review. The 33% of cases (5/15) had a familiar history of EEC, thus, we found one case of consanguinity of parents. Anomalies EEC-related were recognized in the 40% of cases (6/15). An association with genitourinary anomalies was found in 30% (5/15) of them. CONCLUSIONS A strong suspicion of final diagnosis of EEC may be done in the presence of ectrodactyly, facial clefting and urinary malformation especially in cases of negative family history. More attention should be given to a genetic counseling, especially to understand a possible relation to other genetic syndromes.

Abstract
A thermodynamic the influence of temperature on the logarithm of the considered quantity is expressed by bifunctional functional terms (1/T, lnT). For this purpose, the Apelblat & Manzurola (A&M) equation was used for extended model dissolution analysis of 12 aromatic hydrocarbons in tetralin and decalin vs. temperature for saturated solutions. The A&M equation was found to be thermodynamically compensatory in the sense of Enthalpy-Entropy-Compensation (EEC) while limiting melting temperature Tm=∆mH∆mS. The coefficients for the functional terms A1 vs. A2 are a linear relationship, with a slope called the compensation temperature Tc, as ratio of average enthalpy to average entropy. From this dependence, it has been shown that the approximation of ∆cp=∆mS¯ is justified, also assuming the average entropy. Regarding the term representing the activity coefficients, modifications to the A&M equation were proposed by replacing the intercept and it was shown that the new form correctly determines ∆mH. However, the condition is that the molar fraction of the solute exceeds x > 0.5 moles. It has been shown that the simplest equation referred to van ’t Hoff’s isobar also allows the simultaneous determination of enthalpy and entropy, but these quantities do not always come down to melting temperature.

Abstract
Ectrodactyly-ectodermal dysplasia-cleft (EEC) syndrome is an autosomal dominant disorder characterized by ectrodactyly, ectodermal dysplasia, and orofacial clefting. Reduced penetrance is manifested in these core features and additional under-recognized features, especially in prenatal cases. Here, we present a fetus with EEC syndrome at 22 weeks gestation, in which the cleft lip and palate and the right polycystic kidney are shown by prenatal ultrasound. A de novo missense mutation of R304W in the TP63 gene is confirmed by whole-exome sequencing associated with EEC syndrome. We further investigate the reported TP63-related prenatal cases and provide a more complete picture of the prenatal phenotypic spectrum about EEC. It illustrates the potential severity of genitourinary anomalies in TP63-related disorders and highlights the need to counsel for the possibility of EEC syndrome, given the occurrence of genitourinary anomalies with orofacial cleft or limb deformities.

Abstract
Congenital Erythrocytosis (CE) can be primary or secondary due to the mutations in genes involved in the erythropoietin receptor and oxygen sensing pathway. In this study, 42 patients with 38 unrelated patients and one family (4 patients) who were JAK-2 mutation (both exon 12 and exon 14) negative with high haematocrit values were investigated. The Endogenous Erythroid colony (EEC) assay was performed in all patients, interestingly EEC colonies were high in EPAS1 and EPOR mutated patients compared to non-mutated patients. The sequence analysis of EPAS1 (exon 12), EPO-R (exon-8), VHL (exon-3), and EGLN1 (exon-1) genes in all these patients showed 19% of patients (8/42) had mutations, in exon12 of EPAS1 and exon 8 of EPO-R genes. Two novel missense mutations MW_600850:c.1183G>C, MW_600851:c.1028A>C in EPO-R gene were observed in the study group. One new MW_600849:c.1969C>T nonsense mutation and five MW_619914:c.1715A>G, MW_619915:c.1694G>T, MW_619916:c.1634T>C, MW_600852:c.1771C>G, MW_600848:c.1859G>A novel missense mutations were observed in the EPAS1 gene. Among them, 4 mutations p. (Gln572Arg), p. (Ser565Ile), p. (Ile545Thr), p. (Gln591Glu) in the ODD (Oxygen-dependent degradation) domain of HIF2α, all these variations contributed to the formation of non-functional HIF2α. No mutations were observed in VHL and EGLN1 genes. Using in silico analysis we observed that these mutations contributed to major conformational changes in the HIF2α protein making it non-functional. The mutations in the EPAS1 gene were heterozygous and show autosomal dominant inheritance patterns and we observed in one family. These novel mutations in the EPAS1 (75% (6/8)) and 25% (2/8) EPO-R genes correlating with EEC positivity were observed for the first time in India in CE patients.

Abstract
Purpose The ectodermal dysplasias (EDs) constitute a group of disorders characterized by abnormalities in two or more ectodermal derivatives, including skin, hair, teeth, and sweat glands. The purpose of the current study was to evaluate ocular manifestations in pediatric patients with ED. Methods Retrospective case series including consecutive ED subjects who were treated in the ophthalmology department at the Children’s Hospital of Philadelphia over a 12-year period (2009–2020). Main Outcome Measures were ocular and ocular adnexal abnormalities. Results Thirty subjects were included: 20 males (67%), mean age of 4.5 years (range 0.3–18). Patients with different subtypes were included, with the hypohidrotic ED and ectrodactyly-ectodermal dysplasia-clefting variants being most prevalent. Most common findings were: lacrimal drainage obstruction in 12 (40%) including punctal agenesis in 10 (33%), refractive errors in 13 (43%) and amblyopia in 6 (20%). A new finding of eyelid ptosis or eyelash ptosis was demonstrated in 11 subjects (37%), mostly associated with TP63 or EDA1 genes variants. Conclusion Ectodermal dysplasias are associated with various ocular pathologies and amblyopia in the pediatric population. We report a possible genetic association between lash ptosis and EDA1 gene, and eyelid ptosis and TP63 or EDA1 genes variants.

Abstract
BACKGROUND Patients are often dissatisfied with the symptom control obtained from available pharmacological treatments for seasonal allergic rhinoconjunctivitis (ARC). Therefore, patients seek for alternative, nonpharmacological options to treat their symptoms. Here, we assessed the efficacy of ectoine nasal spray and ectoine eye drops in comparison to placebo to prevent nasal and ocular symptoms following exposure to pollen in patients with ARC. METHODS In this double-blind, randomized, placebo-controlled, cross-over study, 46 patients with ARC applied ectoine eye drops and nasal spray in immediate succession or placebo eye drops and nasal spray for 13 days before ARC symptoms were induced in an environmental exposure chamber. Primary endpoint was the baseline-adjusted area under the curve (AUC) posttreatment total nasal symptom score (TNSS) and the total ocular symptom score (TOSS) using analysis of covariance. Secondary endpoints were, amongst others, total nonnasal symptoms score (TNNSS) and nasal patency (measured using acoustic rhinometry). RESULTS Treatment with both ectoine and placebo reduced TNSS, TOSS, and TNNSS upon allergen exposure. The analysis of parameters at baseline and after allergen exposure demonstrated that ectoine induced a clinically relevant improvement in ARC symptoms compared to placebo: the least square mean difference for baseline-adjusted AUC was -1.87 for TNSS, -1.45 for TOSS and -2.20 for TNNSS. The mean change from baseline AUC of TNNSS for ectoine was also significantly greater than for placebo (-5.49 vs. -3.46; p = 0.011). Ectoine significantly improved the singular symptoms "sneezing," "watery eyes" and "itchy eyes" (p ≤ 0.021) as well as "itchy ear/palate" (p = 0.036) in comparison to placebo. Mean cross sectional areas of the nasal cavity were reduced to a lesser extent after treatment with ectoine (-0.020 ± 0.022) than with placebo (-0.047 ± 0.029). The current study also demonstrated a very good safety profile of ectoine treatment. Few AEs with comparable numbers in both treatment groups were reported during the study, which were mild in severity and resolved without medical treatment. CONCLUSION The study suggests that ectoine is effective in reducing nasal and ocular symptoms associated with ARC. Being a natural, bacteria derived stress protection molecule functioning by a physical mode of action, it therefore represents an alternative nonpharmacological treatment option.

Abstract
Mutations in transcription factor p63 are associated with developmental disorders that manifest defects in stratified epithelia including the epidermis. The underlying cellular and molecular mechanism is however not yet understood. We established an epidermal commitment model using human induced pluripotent stem cells (iPSCs) and characterized differentiation defects of iPSCs derived from ectrodactyly, ectodermal dysplasia, and cleft lip/palate (EEC) syndrome patients carrying p63 mutations. Transcriptome analyses revealed stepwise cell fate transitions during epidermal commitment: Specification from multipotent simple epithelium to basal stratified epithelia and ultimately to the mature epidermal fate. Differentiation defects of EEC iPSCs caused by p63 mutations occurred during the specification switch from the simple epithelium to the basal-stratified epithelial fate. Single-cell transcriptome and pseudotime analyses of cell states identified mesodermal activation that was associated with the deviated commitment route of EEC iPSCs. Integrated analyses of differentially regulated genes and p63-dependent dynamic genomic enhancers during epidermal commitment suggest that p63 directly controls epidermal gene activation at the specification switch and has an indirect effect on mesodermal gene repression. Importantly, inhibitors of mesodermal induction enhanced epidermal commitment of EEC iPSCs. Our findings demonstrate that p63 is required for specification of stratified epithelia, and that epidermal commitment defects caused by p63 mutations can be reversed by repressing mesodermal induction. This study provides insights into disease mechanisms underlying stratified epithelial defects caused by p63 mutations and suggests potential therapeutic strategies for the disease.

Abstract
BACKGROUND The goal of this review is to evaluate the value of ultrasound for detection of retained products of conception (RCOP) after delivery. METHODS A systematic search was performed using 'postpartum', 'retained placenta', 'retained products' and 'ultrasound' resulting 82 publications, after screening titles and abstracts, 30 remained. RESULTS On gray scale ultrasound, one must be focus on a thickened endometrial echo complex (EEC) with a cut off value of 10 mm and on an intracavitary mass. If these features are not visible, RPOC is rare. However, these findings are neither specific nor conclusive for RPOC and can even be seen in a normal postpartum uterus. Detection of hypervascularity in a thickened EEC or intracavitary mass with color Doppler ultrasound is very sensitive for RPOC but still not specific nor can it exclude RPOC. MRI seems best in differentiating RPOC, arteriovenous malformations and gestational trophoblastic disease. CONCLUSION There is no consensus on a standardised method for postpartum ultrasound. More research and standardization are necessary to differentiate of normal and pathological findings in the postpartum uterus.

Abstract
The cardinal features of Ectrodactyly, Ectodermal dysplasia, Cleft lip/palate (EEC), and Ankyloblepharon-Ectodermal defects-Cleft lip/palate (AEC) syndromes are ectodermal dysplasia (ED), orofacial clefting, and limb anomalies. EEC and AEC are caused by heterozygous mutations in the transcription factor p63 encoded by TP63. Here, we report a patient with an EEC/AEC syndrome-like phenotype, including ankyloblepharon, ED, cleft palate, ectrodactyly, syndactyly, additional hypogammaglobulinemia, and growth delay. Neither pathogenic mutations in TP63 nor CNVs at the TP63 locus were identified. Exome sequencing revealed de novo heterozygous variants in CHUK (conserved helix-loop-helix ubiquitous kinase), PTGER4, and IFIT2. While the variant in PTGER4 might contribute to the immunodeficiency and growth delay, the variant in CHUK appeared to be most relevant for the EEC/AEC-like phenotype. CHUK is a direct target gene of p63 and encodes a component of the IKK complex that plays a key role in NF-κB pathway activation. The identified CHUK variant (g.101980394T>C; c.425A>G; p.His142Arg) is located in the kinase domain which is responsible for the phosphorylation activity of the protein. The variant may affect CHUK function and thus contribute to the disease phenotype in three ways: (1) the variant exhibits a dominant negative effect and results in an inactive IKK complex that affects the canonical NF-κB pathway; (2) it affects the feedback loop of the canonical and non-canonical NF-κB pathways that are CHUK kinase activity-dependent; and (3) it disrupts NF-κB independent epidermal development that is often p63-dependent. Therefore, we propose that the heterozygous CHUK variant is highly likely to be causative to the EEC/AEC-like and additional hypogammaglobulinemia phenotypes in the patient presented here.

Abstract
INTRODUCTION Treatment of cataract blindness is surgical to restore vision. The aim of this work was to compare the PKA to the classic EEC in the surgical treatment of adult cataract in terms of anatomical and functional results in our institute. MATERIALS AND METHODS This was a cross-sectional study of 333 operated eyes of cataract of the adult and followed for one month. The postoperative functional data and the causes of poor results were specified. RESULT A total of 172 men (51.7%) and 161 women (48.3%) underwent cataract surgery. The mean age was 64.2 years. 61.26% of patients had visual acuity (≥3 / 10) in EEC compared with 65.28% in PKA. (21%) for EEC, and (15%) for PKA had poor visual acuity (<1/10). The proportion of patients with good results increases with the best correction to 77.3% for EEC and 91.5% for PKA. The poor results close to those of the WHO in both techniques (6.7%). EEC and (5.3%) PKA. The poor results were mainly related to pre-existing pathologies (6.6%) and astigmatism related to surgery (7.1%). CONCLUSION In order to achieve the objectives of "Vision 2020", within the framework of the fight against blindness, it is imperative to facilitate the popularization of the PKA throughout the African subregion.

Abstract
Long noncoding RNAs (lncRNAs) are emerging as important modulators in the biological processes and tumorigenesis. However, whether lncRNAs are involved in endometrial endometrioid adenocarcinoma (EEC) remains unclear. In the present study, we explored the expression pattern, clinical significance and biological function of nuclear enriched abundant transcript 1 (NEAT1) in EEC. The expression levels of NEAT1 were elevated in EEC tissues and cell lines, and higher expression levels of NEAT1 were positively correlated with FIGO stage and lymph node metastasis. Overexpression of NEAT1 in HEC-59 cells transfected with pGCMV-NEAT1 promotes cell growth, colony formation ability as well as invasive and migratory ability; while knock-down of NEAT1 in HEC-59 cells by siNEAT1 transfection exhibited the opposite effects. Flow cytometry analysis showed that overexpression of NEAT1 led to an increase in S-phase cells and attenuated cell apoptosis, and knock-down of NEAT1 induced G0/G1 arrest and also induced cell apoptosis in HEC-59 cells. Tumor metastasis real-time PRC array showed that six metastasis-related genes (c-myc, insulin like growth factor 1(IGF1), matrix metallopeptidase 2 (MMP-2) and matrix metallopeptidase 7(MMP-7) were up-regulated, and Cadherin 1 and TIMP metallopeptidase inhibitor 2 were down-regulated) in NEAT1-overexpressing HEC-59 cells. Further qRT-PCR and western blot results confirmed that c-myc, IFG1, MMP-2 and MMP-7 were dys-regulated by NEAT1. Together, our data underscore the significance of NEAT1 in EEC development, and NEAT1 may a potential therapeutic target for EEC.

Abstract
In this study, measurements of indoor radon ((222)Rn), thoron ((220)Rn) and their equilibrium equivalent concentration (EEC) were carried out in 96 dwellings from 22 different villages situated in Hamirpur district, Himachal Pradesh, India, by using LR-115 type II-based pinhole twin cup dosimeters and deposition-based progeny sensors (DRPS/DTPS). The annual average indoor (222)Rn and (220)Rn concentrations observed in these dwellings were 63.82 and 89.59 Bq/m(3), respectively, while the average EEC (attached + unattached) for (222)Rn and (220)Rn was 29.28 and 2.74 Bq/m(3). For (222)Rn (f Rn) and (220)Rn (f Tn), the average values of unattached fraction were 0.11 and 0.09, respectively. The equilibrium factors for radon (F Rn) and thoron (F Tn) varied from 0.12 to 0.77 with an average of 0.50, and from 0.01 to 0.34 with an average of 0.05, respectively. The annual inhalation dose due to mouth and nasal breathing was calculated using dose conversion factors and unattached fractions. The indoor annual effective doses for (222)Rn (AEDR) and (220)Rn (AEDT) were found to be 1.92 and 0.83 mSv a(-1), respectively. The values of (222)Rn/(220)Rn concentrations and annual effective doses obtained in the present study are within the safe limits as recommended by the International Commission on Radiological Protection for indoor dwelling exposure conditions.

Abstract
Endometrial cancer is the most common gynecologic malignancy and about 80% of these cancers are endometrial endometrioid carcinoma (EEC). Previously, we have demonstrated that protocadherin 10 (PCDH10) is a tumor suppressor gene in EEC, and in this study we further explored the molecular mechanisms of PCDH10 in EEC. We first detect the PCDH10 expression in EEC tissues and then investigate the mechanism in two EEC cell lines. The mRNA and protein expression levels were measured by quantitative real time PCR (qRT-PCR) and western blot, respectively; Cell growth was determined by MTS, CCK-8 and colony formation assays; Cell cycle was determined by flow cytometry, and cell apoptosis was examined by flow cytometry and TUNEL assay. The downstream mediator of PCHD10 was confirmed by Topflash luciferase reporter assay. QRT-PCR and western blot results showed that PCDH10 was down-regulated in EEC clinical tissues. Restoration of PCDH10 suppressed cell growth and induced apoptosis in EEC cells. Dishevelled, EGL-10 and Pleckstrin domain containing 1 (DEPDC1) was a potential downstream mediator of PCDH10 as revealed by RNA-sequencing, and mechanistic studies suggested that DEPDC1 is a downstream mediator and promotes cell growth and induces apoptosis in EEC cells. Western blot further showed that PCDH10 restoration activate apoptotic signaling pathway via caspase signaling in both EEC cell lines and EEC clinical tissues. Collectively, our results suggest that PCDH10-DEPDC1-caspase signaling may be a novel regulatory axis in EEC development and it will be of great interest to explore the clinical significance of PCDH10 and DEPDC1 in the future.

Abstract
High concentration of radon ((222)Rn), thoron ((220)Rn) and their decay products in environment may increase the risk of radiological exposure to the mankind. The (222)Rn, (220)Rn concentration and their separate attached and unattached progeny concentration in units of EEC have been measured in the dwellings of Muktsar and Mansa districts of Punjab (India), using Pin-hole cup dosimeters and deposition based progeny sensors (DTPS/DRPS). The indoor (222)Rn and (220)Rn concentration was found to vary from 21 Bqm(-3) to 94 Bqm(-3) and 17 Bqm(-3) to 125 Bqm(-3). The average EEC (attached + unattached) of (222)Rn and (220)Rn was 25 Bqm(-3) and 1.8 Bqm(-3). The equilibrium factor for (222)Rn and (220)Rn in studied area was 0.47 ± 0.13 and 0.05 ± 0.03. The equilibrium factor and unattached fraction of (222)Rn and (220)Rn has been calculated separately. Dose conversion factors (DCFs) of different models have been calculated from unattached fraction for the estimation of annual effective dose in the studied area. From the experimental data a correlation relationship has been observed between unattached fraction (f(p)(Rn)) and equilibrium factor (F(Rn)). The present work also aims to evaluate an accurate expression among available expression in literature for the estimation of f(p)(Rn).

Abstract
p63, a member of the p53 family, is a crucial transcription factor for epithelial development and skin homeostasis. Heterozygous mutations in TP63 gene have been associated with human ectodermal dysplasia disorders. Most of these TP63 mutations are missense mutations causing amino acidic substitutions at p63 DNA binding or SAM domains that reduce or abolish the transcriptional activity of mutants p63. A significant number of mutants, however, resides in part of the p63 protein that apparently do not affect DNA binding and/or transcriptional activity, such as the N-terminal domain. Here, we characterize five p63 mutations at the 5' end of TP63 gene aiming to understand the pathogenesis of the diseases and to uncover the role of ΔNp63α N-terminus residues in determining its transactivation potential.

Abstract
To determine the natural radiation exposure due to outdoor radon ((222)Rn) and its short-lived decay products in Germany, the Federal Office for Radiation Protection (BfS) conducted a measuring programme over three years. The annual mean radon concentration at 1.5 m above ground level was measured with solid-state track etch detectors at 173 measuring points in an even grid with a grid length of approx. 50 km. Furthermore, annual mean values of the equilibrium-equivalent radon concentration (EEC) and the equilibrium factor were estimated on the basis of the activity concentrations of (214)Pb and (214)Bi measured at 27 stations of the German Meteorological Service (DWD). Our study yielded a spatial mean outdoor radon concentration for Germany of 9 ± 1 Bq m(-3) (median: 8 (-0.5/+1.0) Bq m(-3)), with regional means varying from 4.5 Bq m(-3) in Hamburg to 14 Bq m(-3) in Bavaria. The determined EEC are in a range from 1.4 to 11 Bq m(-3).

Abstract
Vulnerability of the fetus upon maternal obesity can potentially occur during all developmental phases. We aimed at elaborating longer-term health outcomes of fetal overnutrition during the earliest stages of development. We utilized Naval Medical Research Institute (NMRI) mice to induce pre-conceptional and gestational obesity and followed offspring outcomes in the absence of any postnatal obesogenic influences. Male adult offspring developed overweight, insulin resistance, hyperleptinemia, hyperuricemia and hepatic steatosis; all these features were not observed in females. Instead, they showed impaired fasting glucose and a reduced fat mass and adipocyte size. Influences of the interaction of maternal diet∗sex concerned offspring genes involved in fatty liver disease, lipid droplet size regulation and fat mass expansion. These data suggest that a peri-conceptional obesogenic exposure is sufficient to shape offspring gene expression patterns and health outcomes in a sex- and organ-specific manner, indicating varying developmental vulnerabilities between sexes towards metabolic disease in response to maternal overnutrition.

Abstract
Vulnerability of the fetus upon maternal obesity can potentially occur during all developmental phases. We aimed at elaborating longer-term health outcomes of fetal overnutrition during the earliest stages of development. We utilized Naval Medical Research Institute (NMRI) mice to induce pre-conceptional and gestational obesity and followed offspring outcomes in the absence of any postnatal obesogenic influences. Male adult offspring developed overweight, insulin resistance, hyperleptinemia, hyperuricemia and hepatic steatosis; all these features were not observed in females. Instead, they showed impaired fasting glucose and a reduced fat mass and adipocyte size. Influences of the interaction of maternal diet∗sex concerned offspring genes involved in fatty liver disease, lipid droplet size regulation and fat mass expansion. These data suggest that a peri-conceptional obesogenic exposure is sufficient to shape offspring gene expression patterns and health outcomes in a sex- and organ-specific manner, indicating varying developmental vulnerabilities between sexes towards metabolic disease in response to maternal overnutrition.

Abstract
FGFs, in a complex with their receptors (FGFRs) and heparan sulfate (HS), are responsible for a range of cellular functions, from embryogenesis to metabolism. Both germ line and somatic FGFR mutations are known to play a role in a range of diseases, most notably craniosynestosis dysplasias, dwarfism and cancer. Because of the ability of FGFR signalling to induce cell proliferation, migration and survival, FGFRs are readily co-opted by cancer cells. Mutations in, and amplifications of, these receptors are found in a range of cancers with some of the most striking clinical findings relating to their contribution to pathogenesis and progression of female cancers. Here, we outline the molecular mechanisms of FGFR signalling and discuss the role of this pathway in women's cancers, focusing on breast, endometrial, ovarian and cervical carcinomas, and their associated preclinical and clinical data. We also address the rationale for therapeutic intervention and the need for FGFR-targeted therapy to selectively target cancer cells in view of the fundamental roles of FGF signalling in normal physiology.

Abstract
The congenital vomer defect (CVD) is a rare and still partially unknown condition. Only few cases have been reported in the international literature and the large majority of them appeared to be isolated. We report a case of CVD detected in a 7-year-old girl affected by ectodermal dysplasia clefting syndrome caused by a mutation of the TP63 gene.

Abstract
BACKGROUND H1-receptor inverse agonists are used effectively for treating several symptoms of allergic rhinitis, including nasal itching, rhinorrhea, and sneezing, although most agents are not very effective in treating nasal congestion. OBJECTIVE This study evaluated the relative efficacy of a novel selective H3-receptor antagonist, JNJ-39220675, in preventing nasal congestion induced by exposing participants with ragweed allergy to ragweed allergen in an environmental exposure chamber model. METHODS In this single-dose, patient-blind, double-dummy, placebo- and active-controlled, phase IIa cross-over study, 53 participants were randomized to JNJ-39220675 plus placebo, placebo plus pseudoephedrine, or only placebo. The primary efficacy assessment was change in nasal patency assessed by measuring the minimal cross-sectional area of the nasal cavity by using acoustic rhinometry. Secondary assessment included total nasal symptom scores (TNSSs) over the 8-hour environmental exposure chamber exposure period. RESULTS Smaller decreases in minimal cross-sectional area were observed after JNJ-39220675 (least square mean difference, -0.126; P = .06) and pseudoephedrine (least square mean difference, -0.195; P = .004) treatment compared with placebo. The means for the baseline-adjusted area under the curve of TNSSs were significantly smaller for JNJ-39220675 (P = .0003) and pseudoephedrine (P = .04) versus placebo. JNJ-39220675 was significantly effective in treating all 4 individual symptoms (P ≤ .05 for all scores) compared with placebo, whereas pseudoephedrine only showed a trend for improvement in individual symptom scores of the TNSS. Insomnia was the most frequent adverse event (17.3%) associated with JNJ-39220675 treatment. CONCLUSION Prophylactic treatment with the H3-antagonist JNJ-39220675 relieved allergen-induced nasal congestion by using standard nasal symptom scoring; however, in contrast to pseudoephedrine, it only showed a trend for increasing nasal patency by using objective measures.

Abstract
This interaction of four novel 9-O-substituted analogs of the plant alkaloid berberine with double stranded poly(A) was studied using a variety of biophysical techniques. Remarkably higher binding of two 9-O-ω-amino alkyl ether analogs compared to the two 9-O-N-aryl/arylalkyl amino carbonyl methyl berberine analogs was observed. Quantum efficiency values suggested that energy was transferred from the adenine base pairs to the analogs on binding. Ferrocyanide quenching and viscosity studies revealed the binding mode to be intercalative for these analogs. Circular dichroism studies showed that these analogs induced significant conformational changes in the secondary structure of ds poly(A). Energetics of the binding suggested that 9-O-N-aryl/arylalkyl amino carbonyl methyl berberines bound very weakly to ds poly(A). The binding of 9-O-ω-amino alkyl ether analogs was entropy dominated with a smaller but favorable enthalpic contribution to the Gibbs energy. Increasing the temperature resulted in weaker binding; the enthalpic contribution increased and the entropic contribution decreased. A small negative heat capacity change with significant enthalpy-entropy compensation established the involvement of multiple weak noncovalent interactions in the binding process.
