Abstract
Structurally well-defined graphene nanoribbons (GNRs) are nanostructures with unique optoelectronic properties. In the liquid phase, strong aggregation typically hampers the assessment of their intrinsic properties. Recently we reported a novel type of GNRs, decorated with aliphatic side chains, yielding dispersions consisting mostly of isolated GNRs. Here we employ two-dimensional electronic spectroscopy to unravel the optical properties of isolated GNRs and disentangle the transitions underlying their broad and rather featureless absorption band. We observe that vibronic coupling, typically neglected in modeling, plays a dominant role in the optical properties of GNRs. Moreover, a strong environmental effect is revealed by a large inhomogeneous broadening of the electronic transitions. Finally, we also show that the photoexcited bright state decays, on the 150 fs time scale, to a dark state which is in thermal equilibrium with the bright state, that remains responsible for the emission on nanosecond time scales.

Abstract
In this work, we show how the structural features of photoactive azobenzene derivatives can influence the photoexcited state behavior and the yield of the trans/cis photoisomerization process. By combining high-resolution transient absorption experiments in the vis-NIR region and quantum chemistry calculations (TDDFT and RASPT2), we address the origin of the transient signals of three poly-substituted push-pull azobenzenes with an increasing strength of the intramolecular interactions stabilizing the planar trans isomer (absence of intramolecular H-bonds, methyl, and traditional H-bond, respectively, for 4-diethyl-4'-nitroazobenzene, Disperse Blue 366, and Disperse Blue 165) and a commercial red dye showing keto-enol tautomerism involving the azo group (Sudan Red G). Our results indicate that the intramolecular H-bonds can act as a "molecular lock" stabilizing the trans isomer and increasing the energy barrier along the photoreactive CNNC torsion coordinate, thus preventing photoisomerization in the Disperse Blue dyes. In contrast, the involvement of the azo group in keto-enol tautomerism can be employed as a strategy to change the nature of the lower excited state and remove the nonproductive symmetric CNN/NNC bending pathway typical of the azo group, thus favoring the productive torsional motion. Taken together, our results can provide guidelines for the structural design of azobenzene-based photoswitches with a tunable excited state behavior.

Abstract
Nonlinear spectroscopy with quantum entangled photons is an emerging field of research that holds the promise to achieve superior signal-to-noise ratio and effectively isolate many-body interactions. Photon sources used for this purpose, however, lack the frequency tunability and spectral bandwidth demanded by contemporary molecular materials. Here, we present design strategies for efficient spontaneous parametric downconversion to generate biphoton states with adequate spectral bandwidth and at visible wavelengths. Importantly, we demonstrate, by suitable design of the nonlinear optical interaction, the scope to engineer the degree of spectral correlations between the photons of the pair. We also present an experimental methodology to effectively characterize such spectral correlations. Importantly, we believe that such a characterization tool can be effectively adapted as a spectroscopy platform to optically probe system-bath interactions in materials.

Abstract
Summary Vespa velutina nigrithorax (VVN), commonly known as Asian wasp because endemic in Asia, represents an alien species in Europe. VVN can induce allergic reactions similar to those caused by other Hymenoptera and deaths after VVN stings, presumably due to fatal allergic reactions, were reported. In the treatment of Hymenoptera venom hypersensitivity, specific immunotherapy (VIT) is highly effective, and the vaccine allergen-specificity plays a crucial role. Currently, there is no specific available VIT for VVN, so VVN stung patients with severe systemic reactions are treated with Vespula spp (Vspp) venom. It is also relevant to assess if patients stung by VVN and showing allergic reactions could be treated with the Hymenoptera commercially available extracts Vespa crabro (VC) and Vspp, or if they need the specific VIT with VVN venom extract. Our results suggested that both Vspp and VC venoms were able to inhibit the specific IgE for VVN, although the VC venom, compared to the venom of Vspp showed a higher inhibition.

Abstract
PURPOSE Many questions concerning Turner syndrome (TS) remain unresolved, such as the long-term complications and, therefore, the optimal care setting for adults. The primary aim of this long-term cohort study was to estimate the incidence of comorbid conditions along the life course. METHODS A total of 160 Italian patients with TS diagnosed from 1967 to 2010 were regularly and structurally monitored from the diagnosis to December 2019 at the University Hospital of Bologna using a structured multidisciplinary monitoring protocol. RESULTS The study cohort was followed up for a median of 27 years (IQR 12-42). Autoimmune diseases were the comorbid condition with the highest incidence (61.2%), followed by osteoporosis and hypertension (23.8%), type 2 diabetes (16.2%) and tumours (15.1%). Median age of onset ranged from 22 years for autoimmune diseases to 39 years for type 2 diabetes. Malignant tumours were the most prominent type of neoplasm, with a cumulative incidence of 11.9%. Papillary thyroid carcinoma was the most common form of cancer, followed by skin cancer and cancer of the central nervous system. Only one major cardiovascular event (acute aortic dissection) was observed during follow-up. No cases of ischaemic heart disease, heart failure, stroke or death were recorded. CONCLUSIONS This cohort study confirms the need for continuous, structured and multidisciplinary lifelong monitoring of TS, thus ensuring the early diagnosis of important comorbid conditions, including cancer, and their appropriate and timely treatment. In addition, these data highlight the need for the increased surveillance of specific types of cancer in TS, including thyroid carcinoma.

Abstract
Spectrally resolved measurements of optical activity, such as circular dichroism (CD) and optical rotatory dispersion (ORD), are powerful tools to study chiroptical properties of (bio)molecular and nanoplasmonic systems. The wider utilization of these techniques, however, has been impeded by the bulky and slow design of conventional spectropolarimeters, which have been limited to a narrowband scanning approach for more than 50 years. In this work, we demonstrate broadband measurements of optical activity by combining a balanced detection scheme with interferometric Fourier-transform spectroscopy. The setup utilizes a linearly polarized light field that creates an orthogonally polarized weak chiral free-induction-decay field, along with a phase-locked achiral transmitted signal, which serves as the local oscillator for heterodyne amplification. By scanning the delay between the two fields with a birefringent common-path interferometer and recording their interferogram with a balanced detector that measures polarization rotation, broadband CD and ORD spectra are retrieved simultaneously with a Fourier transform. Using an incoherent thermal light source, we achieve state-of-the-art sensitivity for CD and ORD across a broad wavelength range in a remarkably simple setup. We further demonstrate the potential of our technique for highly sensitive measurements of glucose concentration and the real-time monitoring of ground-state chemical reactions. The setup also accepts broadband pulses and will be suitable for broadband transient optical activity spectroscopy and broadband optical activity imaging.

Abstract
We present diffraction-limited photocurrent (PC) microscopy in the visible spectral range based on broadband excitation and an inherently phase-stable common-path interferometer. The excellent path-length stability guarantees high accuracy without the need for active feedback or post-processing of the interferograms. We illustrate the capabilities of the setup by recording PC spectra of a bulk GaAs device and compare the results to optical transmission data.

Abstract
The full control of the fundamental photophysics of nanosystems at frequencies as high as few THz is key for tunable and ultrafast nanophotonic devices and metamaterials. Here we combine geometrical and ultrafast control of the optical properties of halide perovskite nanoparticles, which constitute a prominent platform for nanophotonics. The pulsed photoinjection of free carriers across the semiconducting gap leads to a subpicosecond modification of the far-field electromagnetic properties that is fully controlled by the geometry of the system. When the nanoparticle size is tuned so as to achieve the overlap between the narrowband excitons and the geometry-controlled Mie resonances, the ultrafast modulation of the transmittivity is completely reversed with respect to what is usually observed in nanoparticles with different sizes, in bulk systems, and in thin films. The interplay between chemical, geometrical, and ultrafast tuning offers an additional control parameter with impact on nanoantennas and ultrafast optical switches.

Abstract
We introduce a high-performance hyperspectral camera based on the Fourier-transform approach, where the two delayed images are generated by the Translating-Wedge-Based Identical Pulses eNcoding System (TWINS) [Opt. Lett. 37, 3027 (2012)], a common-path birefringent interferometer that combines compactness, intrinsic interferometric delay precision, long-term stability and insensitivity to vibrations. In our imaging system, TWINS is employed as a time-scanning interferometer and generates high-contrast interferograms at the single-pixel level. The camera exhibits high throughput and provides hyperspectral images with spectral background level of -30dB and resolution of 3 THz in the visible spectral range. We show high-quality spectral measurements of absolute reflectance, fluorescence and transmission of artistic objects with various lateral sizes.

Abstract
Single-molecule spectroscopy (SMS) provides a detailed view of individual emitter properties and local environments without having to resort to ensemble averaging. While the last several decades have seen substantial refinement of SMS techniques, recording excitation spectra of single emitters still poses a significant challenge. Here we address this problem by demonstrating simultaneous collection of fluorescence emission and excitation spectra using a compact common-path interferometer and broadband excitation, which is implemented as an extension of a standard SMS microscope. We demonstrate the technique by simultaneously collecting room-temperature excitation and emission spectra of individual terrylene diimide molecules and donor-acceptor dyads embedded in polystyrene. We analyze the resulting spectral parameters in terms of optical lineshape theory to obtain detailed information on the interactions of the emitters with their nanoscopic environment. This analysis finally reveals that environmental fluctuations between the donor and acceptor in the dyads are not correlated.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive enlargement of kidney cysts, leading to chronic kidney disease. Since the available treatment for ADPKD is limited, there is emerging interest for natural compounds as potential therapeutic candidates. The aim of our study was to investigate whether an olive leaf extract may be able to counteract the cyst growth in an in vitro model of ADPKD. We treated WT9-12 cells with an olive leaf extract (OLE). In monolayer culture we evaluated cell viability by the MTT assay, protein expression by western-blot analysis and apoptosis by DNA laddering and TUNEL assays. For functional studies we used transient transfection and ChIP assays. Intracellular calcium measurement was performed with a spectrofluorimeter using a fluorescent probe. 3D-cell-culture was used for cyst growth studies. OLE reduced the WT9-12 cell growth rate and affected intracellular signaling due to high c-AMP levels, as OLE reduced PKA levels, enhanced p-AKT, restored B-Raf-inactivation and down-regulated p-ERK. We elucidated the molecular mechanism by which OLE, via Sp1, transactivates the p21WAF1/Cip1 promoter, whose levels are down-regulated by mutated PKD1. We demonstrated that p-AKT up-regulation also played a crucial role in the OLE-induced anti-apoptotic effect and that OLE ameliorated intracellular calcium levels, the primary cause of ADPKD. Finally, using a 3D-cell-culture model we observed that OLE reduced the cyst size. Therefore, multifaceted OLE may be considered a new therapeutic approach for ADPKD treatment.

Abstract
Diagnostic ultrasound (US) images can be obtained from a quality device, in optimal working conditions, combined with the capable actions of the operator in tweaking the equipment's characteristics. The quality assurance (QA) is the topic of this review article, and it is addressed in an US practice through proper selection of the equipment when purchasing, and through care and preventive maintenance of the machine for ensuring accurate performance. For optimal US system functioning, QA steps carried out on the basis of a scheduled program are needed in any US practice or department. It is critical to confirm in a semiannual or annual basis that the image quality is maintained according to standards and any subtle change in equipment's functioning is detected and amended at an early stage. The use of test objects (also called US testing phantoms) is required above the basic level of QA testing. The scope of this review article is to inform the US user about necessary QA knowledge and at the same time, present the state of the art of the most suitable test methods for US QA. We referred to relevant publications, selected after performing a systematic literature search of the MEDLINE, EMBASE and COCHRANE databases, and also to the standards established by authoritative international societies.

Abstract
Experimental evidence demonstrated that macroautophagy/autophagy exerts a crucial role in maintain renal cellular homeostasis and represents a protective mechanism against renal injuries. Interestingly, it has been demonstrated that in the human proximal tubular renal cell line, HK-2, the MTOR inhibitor rapamycin enhanced autophagy and mitigated the apoptosis damage induced by urinary protein overload. However, the underlying molecular mechanism has not yet been elucidated. In our study we demonstrated, for the first time, that in HK-2 cells, the exposure to low doses of rapamycin transactivated the NGFR promoter, leading to autophagic activation. Indeed, we observed that in HK-2 cells silenced for the NGFR gene, the rapamycin-induced autophagic process was prevented, as the upregulation of the proautophagic markers, BECN1, as well as LC3-II, and the autophagic vacuoles evaluated by transmission electron microscopy, were not found. Concomitantly, using a series of deletion constructs of the NGFR promoter we found that the EGR1 transcription factor was responsible for the rapamycin-mediated transactivation of the NGFR promoter. Finally, our results provided evidence that the cotreatment with rapamycin plus albumin further enhanced autophagy via NGFR activation, reducing the proapoptotic events promoted by albumin alone. This effect was prevented in HK-2 cells silenced for the NGFR gene or pretreated with the MTOR activator, MHY1485. Taken together, our results describe a novel molecular mechanism by which rapamycin-induced autophagy, mitigates the tubular renal damage caused by proteinuria, suggesting that the use of low doses of rapamycin could represent a new therapeutic strategy to counteract the tubule-interstitial injury observed in patients affected by proteinuric nephropathies, avoiding the side effects of high doses of rapamycin.

Abstract
We introduce a novel configuration for the broadband measurement of the optical activity of molecules, combining time-domain detection with heterodyne amplification. A birefringent common-path polarization-division interferometer creates two phase-locked replicas of the input light with orthogonal polarization. The more intense replica interacts with the sample, producing a chiral free-induction decay field, which interferes with the other replica, acting as a time-delayed phase-coherent local oscillator. By recording the delay-dependent interferogram, we obtain by a Fourier transform both the circular dichroism and circular birefringence spectra. Our compact, low-cost setup accepts ultrashort light pulses, making it suitable for measurement of transient optical activity.

Abstract
We introduce a broadband single-pixel spectro-temporal fluorescence detector, combining time-correlated single photon counting (TCSPC) with Fourier transform (FT) spectroscopy. A birefringent common-path interferometer (CPI) generates two time-delayed replicas of the sample's fluorescence. Via FT of their interference signal at the detector, we obtain a two-dimensional map of the fluorescence as a function of detection wavelength and emission time, with high temporal and spectral resolution. Our instrument is remarkably simple, as it only requires the addition of a CPI to a standard single-pixel TCSPC system, and it shows a readily adjustable spectral resolution with inherently broad bandwidth coverage.

Abstract
We present a multimodal non-linear optical (NLO) laser-scanning microscope, based on a compact fiber-format excitation laser and integrating coherent anti-Stokes Raman scattering (CARS), stimulated Raman scattering (SRS) and two-photon-excitation fluorescence (TPEF) on a single platform. We demonstrate its capabilities in simultaneously acquiring CARS and SRS images of a blend of 6-μm poly(methyl methacrylate) beads and 3-μm polystyrene beads. We then apply it to visualize cell walls and chloroplast of an unprocessed fresh leaf of Elodea aquatic plant via SRS and TPEF modalities, respectively. The presented NLO microscope, developed in house using off-the-shelf components, offers full accessibility to the optical path and ensures its easy re-configurability and flexibility.

Abstract
We report on a Yb-pumped optical parametric oscillator (OPO) that delivers 30 fs pulses with spectral coverage from 680 to 910 nm and an average output power of up to 1.1 W. The resulting peak power is ∼0.5 MW, which is, to the best of our knowledge, the highest ever demonstrated in a femtosecond OPO. The intensity noise remains at a level of 0.2% rms, and rapid wavelength tuning is obtained by simply scanning the resonator length. The performances of the OPO are promising for a variety of applications in nonlinear microscopy and ultrafast spectroscopy.

Abstract
The correlation of molecular excitation and emission events provides a powerful multidimensional spectroscopy tool, by relating transitions from electronic ground and excited states through two-dimensional excitation-emission maps. Here we present a compact, fast and versatile Fourier-transform spectrometer, combining absorption and excitation-emission fluorescence spectroscopy in the visible. We generate phase-locked excitation pulse pairs via an inherently stable birefringent wedge-based common-path interferometer, retaining all the advantages of Fourier-transform spectroscopy but avoiding active stabilization or auxiliary tracking beams. We employ both coherent and incoherent excitation sources on dye molecules in solution, with data acquisition times in the range of seconds and minutes, respectively.

Abstract
PURPOSE Recent evidences indicates that hydroxytyrosol, one of the main olive oil phenols, possess antitumor effects because of its pro-oxidant properties and the capacity to inhibit proliferation and to promote apoptosis in several tumor cell lines, although most of the results were obtained for breast and digestive systems cancers. METHODS In this study, we evaluated the activities of hydroxytyrosol against papillary (TPC-1, FB-2) and follicular (WRO) thyroid cancer cell lines. RESULTS Cellular viability revealed that high doses of hydroxytyrosol reduced cancer cells viability concomitantly with a reduction of cyclin D1 expression and an up-regulation of cell cycle key modulator p21 levels. In the same experimental conditions, Annexin V-PI staining and DNA laddering revealed that hydroxytyrosol exerts proapoptotic effects on papillary and follicular cancer cells. Furthermore, by Western blot analysis, we observed that hydroxytyrosol treatment reduced thyroid cancer cells viability by promoting apoptotic cell death via intrinsic pathway. CONCLUSIONS Collectively, our results demonstrated for the first time that in thyroid cancer cells hydroxytyrosol promoted apoptosis at higher doses with respect to other cancer cells lines. Therefore, further studies will reveal the mechanisms by which thyroid cancer cells are more resistant to the proapoptotic effect exerted by hydroxytyrosol as well as the potential application as novel target therapeutic in thyroid cancer.

Abstract
During peritoneal dialysis (PD), peritoneal mesothelial cells undergo a transition from an epithelial phenotype to a mesenchymal phenotype that, together with the inflammatory process, promotes tissue fibrosis and a failure of peritoneal membrane function. To date, there is no definitive treatment for the progressive thickening and angiogenesis of the peritoneal membrane associated with PD. In this study we tested, in vitro and in vivo, the ability of active compounds extracted from extra virgin olive oil (AC-EVOO) to counteract the mesothelial-to-mesenchymal transition process (MMT) observed in mesothelial cells chronically exposed to the conventional peritoneal dialysate (DL). In particular, we used a cultivar from southern Italy known to have a high polyphenol content. Our results showed that, in mesothelial cells exposed to DL, the combined treatment with AC-EVOO prevented the genic and protein upregulation of key mesenchymal and inflammatory markers, as well as the MCs' migratory capacity. Concomitantly, we tested the antifibrotic efficacy of AC-EVOO in mesothelial cells obtained from effluents of patients undergoing PD, whose "fibroblast-like" phenotype was defined by flow-cytometry assay. We observed that in these cells AC-EVOO significantly mitigated, but did not reverse, the MMT process. In conclusion, our preliminary results suggest that AC-EVOO can interfere with critical factors in the process of differentiation, preventing myofibroblast formation, but once fibrosis has already progressed it is unable to promote the redifferentiation to the epithelial phenotype. Further studies are needed to establish whether AC-EVOO could represent a new therapeutic target to prevent peritoneal fibrosis.

Abstract
OBJECTIVE The cause of elevated blood leukocyte count in pregnancy is unknown. We hypothesized that priming of peripheral polymorphonuclear leukocytes (PMNL) caused this elevation. METHODS Eleven women in the first trimester of pregnancy were included in this prospective study. Peripheral venous blood was drawn twice from each woman, before and after a medical abortion (pregnant and nonpregnant, respectively). Complete blood cell count, plasma alkaline phosphatase (ALP), and rate of superoxide release from separated phobrol 12-myristate-13-acetate (PMA)-stimulated PMNL were determined. RESULTS The PMNL count in early pregnancy was significantly higher, with a significant increase in the PMNL rate of superoxide release compared to the nonpregnant state. A linear correlation between the rates of superoxide release and PMNL counts before and during pregnancy was found. ALP levels were significantly elevated in early pregnancy. CONCLUSION The increased PMNL count is probably a compensatory response to PMNL priming. The increased rate of superoxide release from primed PMNL may contribute to oxidative stress in early pregnancy.

Abstract
BACKGROUND Assessing the risk of cytomegalovirus (CMV) viremia in kidney transplant recipients (KTR) may be helpful to indicate in which patient it is worth starting antiviral treatment during preemptive strategy. METHODS In 40 CMV-seropositive KTR preemptively treated with ganciclovir, we used interferon (IFN)-γ ELISpot test to evaluate whether monitoring T cells directed against phosphoprotein (pp) 65 and immediate early (IE)-1 antigens could predict the onset of viremia. RESULTS CMV viremia occurred in 24 patients (60%) within 120 days after transplantation. Non-viremic patients had higher anti-pp65, anti-IE-1 T cells, and estimated glomerular filtration rate (eGFR) in the first 90 days after transplantation. At logistic regression, anti-pp65, anti-IE-1 T cells, and eGFR measured at day 30 were significantly associated with CMV infection. Cutoff values of 15 spot-forming cells (SFCs)/200,000 peripheral blood mononuclear cells (PBMCs) for anti-IE, 40 SFCs/200,000 PBMCs for anti-pp65, and 46.6 mL/min/1.73 m(2) for eGFR, respectively, predicted the risk of CMV infection with high sensitivity and specificity (area under the receiver operating characteristic curve >0.75). Using a classification tree model, we identified as high-risk patients those showing anti-pp65 <42 SFCs/200,000 PBMCs and eGFR <62 mL/min/1.73 m(2) , as well as anti-pp65 ≥42 and anti-IE-1 <6.5 SFCs/200,000 PBMCs. CONCLUSION Monitoring CMV-specific T-cell responses and eGFR in the first month post transplant can identify patients at high risk of CMV infection, for whom preemptive antiviral therapy is recommended.

Abstract
It has been estimated that nosocomial fever occurs in approximately one-third of hospitalized patients. The incidence is even higher in critically-ill patients in whom both infectious and noninfectious etiologies of fever are common. Polypeptide cytokines (endogenous pyrogens) such as interleukin-1b (IL-1b), tumor necrosis factor (TNF) and interleukin-6 (IL-6) act directly on the hypothalamus to effect a fever response by promoting an increase in heat generation and a decrease in heat loss. There is widespread acceptance that in most if not all critically ill neurologic patients fever should be treated but still it is not clear if fever per se in nonneurologic critically ill patients should be treated too. We review physical and pharmacological methods presently utilized to treat fever in critically ill patients.

Abstract
The LDL receptor-associated protein (RAP) is involved in secretion of thyroglobulin (Tg) from the thyrocyte to the colloid. Disruption of the RAP gene in mice results in a reduced Tg content within the colloid, leading to subclinical hypothyroidism and histological alterations resembling early goiter. Here we studied the entire coding sequence of RAP in genomic DNA samples from 18 patients with primary hypothyroidism not due to thyroid autoimmunity or dysgenesis. The control group included 21 subjects with no evidence of thyroid alterations. Eleven different polymorphisms with amino-acid substitution and 4 different missense polymorphisms without amino-acid substitution were found in various regions of the RAP gene. Only one polymorphism in exone 7 (V311M) was observed exclusively in patients, but it had been previously reported in normal subjects as well. The remaining polymorphisms were found either both in patients and controls or only in controls and had not been previously reported. The frequency of the various polymorphisms did not differ significantly between patients and controls. Based on these findings, we conclude that alterations of the RAP gene are not a common cause of hypothyroidism, although it cannot be excluded that other, rarer alterations with a pathogenic effect exist, and that they should be investigated in a larger number of patients.

Abstract
The Pervasive Developmental Disorders are a very complex and discussed subject both from a clinical point of view and about the etiopathogenesis. Different opinions have generated, in the past, different classification systems based on the underlying theoretical hypothesis. Nowadays the most popular classification systems are the ones contained in the DSM-IV and in the ICD-10. They define these diseases as "conditions characterized by a distortion of base development regarding verbal and non-verbal communication, the reciprocal and social ability of interaction and the imaginative activity." Inside this scenery are also compromised the motion activity, the awareness, the sensorial perception, the humour and the knowledge ability. About the pathogeny, nowadays many authors think autism is based on particular biological conditions, nevertheless they are not well-known or general. The exact origins of the rise of autistic disease are, in fact, still hypothetical. In the same way the concatenation of pathological events determining the arise of such a complex and wide clinical condition is also hypothetical. The discussion is mainly about the classification of childhood autism as a pure organic pathology or as a final expression of organic, psychic, familiar and social factors correlating with wrong operating structures, differentiated from an anatomic and functional point of view. So it seems quite plausible to take into account the possibility of a multisystemic compromise likely generated by a multifactor condition.

Abstract
The prevalence of thyroid diseases in children with Down's syndrome (DS) is about 3%. The most frequently observed condition is autoimmune subclinical hypothyroidism (SH). Autoimmune SH must be distinguished from defects in the biological activity of the TSH molecule or from the rare inherited condition of thyroid resistance to TSH. To investigate this last aspect we studied 12 patients with DS that had moderately elevated TSH with normal free thyroid hormones without signs of autoimmunity. For the genetic analysis the genomic DNA was extracted from peripheral lymphocytes. All the exons of the TSH receptor (TSHr) and Gs(alpha) genes were sequenced. The genetic analysis of the TSHr gene revealed the presence of four polymorphic variants. In two patients there was an allelic variant in the exon 1 (Pro52Thr--in one patient in the heterozygous state and in the other as a homozygous substitution). In one patient there was an allelic variant in the exon 1 (Asp36His) in the heterozygous state. In 11 patients there was a silent polymorphism in the exon 7 at nucleotide 561. All patients were homozygous for a silent polymorphism in the exon 9 at nucleotide 855. No inactivating mutations of TSHr or Gs(alpha) genes were identified in the 12 patients. In conclusion, our results seem to exclude the role of TSHr or Gs(alpha) gene mutations in the pathogenesis of the non-autoimmune SH observed in some children with DS.

Abstract
In this report we describe a 47-yr-old woman who was referred to our department for elevated serum TSH associated with normal free thyroid hormone levels, suggesting subclinical hypothyroidism. When first seen she was clinically euthyroid, and her thyroid gland was normal in size both at palpation and by ultrasound. The ultrasound of the thyroid showed a normoechogenic pattern. Serum thyroid hormone levels were confirmed to be within the normal range, whereas the serum TSH concentration was moderately elevated (13.4 microU/ml). Tests for antithyroperoxidase, antithyroglobulin, and anti-TSH receptor antibodies gave negative results. The only son of the proband, a clinically euthyroid 23-yr-old man, had a slightly elevated serum TSH concentration (5.2 microU/ml) with normal free thyroid hormone levels. The entire coding regions of the TSH receptor gene were sequenced in the proband, the son, and the father of the son. Genetic analysis in the proband showed a homozygous inactivating mutation of the TSH receptor. The mutation consisted of the substitution of an alanine in place of proline at position 162 in the extracellular portion of the receptor. The son was heterozygous for Pro(162)Ala. Only the wild-type sequence was found in the father. Both the proband and her son were considered to have compensated TSH resistance and were not treated. After 2 yr of follow-up, new thyroid tests were performed in the proband and showed a marked increase in the serum TSH concentration (61 microU/ml) compared with the initially observed value; serum free T(4) and T(3) levels were in the low normal range. At that time, tests for antithyroglobulin and antithyroperoxidase antibodies gave positive results, and thyroid echography showed a gland of normal size, but with a diffuse hypoechogenic pattern. In conclusion, we describe the first case of compensated TSH resistance evolving to mild hypothyroidism due to the appearance of a chronic autoimmune thyroiditis.

Abstract
The de novo occurrence of germline-activating thyrotropin receptor (TSHR) gene mutations has been reported as the cause of sporadic nonautoimmune neonatal hyperthyroidism in eight children. We report the case of an Italian infant girl who presented at birth with severe hyperthyroidism and goiter. Ultrasonografic examination of the infant's thyroid showed a diffuse goiter with a normal echogenic pattern. Serum antithyroglobulin, antithyroperoxidase, and antithyrotropin receptor antibodies were undetectable. Treatment with propylthiouracyl, propranolol, and saturated potassium iodide solution started at 44 days of life with the resolution of thyrotoxic symptoms. Once euthyroidism was achieved, the dose of propylthiouracyl was tapered, but hyperthyroidism recurred. Auxological parameters showed an acceleration of linear growth and bone age. DNA was extracted from peripheral white blood cells of the patient, the sister, and the two parents. All of exon 10 of the TSHR gene was amplified by polymerase chain reaction (PCR) and subjected to direct sequencing. In the thyrotoxic infant girl, a substitution of cytosine to thymine was detected, changing isoleucine 568 into a threonine (1568T), located in the second extracellular loop. The normal sequence could also be detected, indicating heterozygosis of the mutated allele. This mutation was previously described as a somatic mutation in a patient with toxic thyroid adenoma. The sister and the parents of the propositus, all euthyroid, showed the wild-type TSHR gene. In conclusion, we describe a case of a de novo germinal mutation of the TSHR causing severe congenital hyperthyroidism.

Abstract
Toxic multinodular goiter, a heterogeneous disease producing hyperthyroidism, is frequently found in iodine-deficient areas. The pathogenesis of this common clinical entity is still unclear. The aim of the present study was to search for activating TSH receptor (TSHr) or Gs alpha mutations in areas of toxic or functionally autonomous multinodular goiters that appeared hyperfunctioning at thyroid scintiscan but did not clearly correspond to definite nodules at physical or ultrasonographic examination. Surgical tissue specimens from nine patients were carefully dissected, matching thyroid scintiscan and thyroid ultrasonography, to isolate hyperfunctioning and nonfunctioning areas even if they did not correspond to well-defined nodules. TSHr and Gs alpha mutations were searched for by direct sequencing after PCR amplification of genomic DNA. Only 2 adenomas were identified at microscopic examination, whereas the remaining 18 hyperfunctioning areas corresponded to hyperplastic nodules containing multiple aggregates of micromacrofollicules not surrounded by a capsule. Activating TSHr mutations were detected in 14 of these 20 hyperfunctioning areas, whereas no mutation was identified in nonfunctioning nodules or areas contained in the same gland. No Gs alpha mutation was found. In conclusion, activating TSHr mutations are present in the majority of nonadenomatous hyperfunctioning nodules scattered throughout the gland in patients with toxic or functionally autonomous multinodular goiter.

Abstract
Congenital hypothyroidism due to impaired thyroid response to TSH was originally described by Stanbury. A diagnosis of congenital hypothyroidism with thyroid unresponsiveness to TSH is accepted if the patient has congenital hypothyroidism, the thyroid gland is in the normal position in the neck, the size of the thyroid is either normal or atrophic, the serum TSH level is increased, the bioactivity of TSH is intact, and the response of the thyroid gland to TSH stimulation is decreased. In all originally described cases serum thyroglobulin was undetectable. We describe a 22-yr-old female patient who was severely hypothyroid and mentally retarded. Serum T4 and T3 concentrations were below the sensitivity of the methods, with elevated serum TSH levels. Serum thyroglobulin was undetectable. A normally shaped hypoplastic gland located in the appropriate anatomical position in the neck was found at scintiscan. The gland did not respond after administration of bovine TSH in terms of 131I uptake, serum thyroid hormones, and thyroglobulin secretion. A diagnosis of congenital hypothyroidism due to TSH unresponsiveness was formulated. Genetic analysis in the propositus showed a homozygous inactivating mutation of the TSH receptor that had not been previously described. The mutation consisted of the substitution of an isoleucine in place of a highly conserved threonine at position 477 in the first extracellular loop of the receptor (T477I). The brother, one sister of the father (whose DNA was not available), the mother of the propositus, one sister, and the brother were heterozygous for T477I. All the heterozygous persons were unaffected. After transfection in COS-7 cells, the mutant receptor displayed an extremely low expression at cell surface. At variance with cells transfected with the wild-type TSH receptor, cells transfected with the mutant T477I did not show constitutive activity for the adenylyl cyclase pathway. A dramatic reduction in the amount of cAMP accumulation after bovine TSH challenge was observed in cells transfected with the mutant T477I receptor. A structural defect in the mutant TSH receptor protein was probably responsible for the poor routing of the receptor to the cell membrane. This is the first time that a loss of function mutation of the TSH receptor is described in a patient with severe congenital hypothyroidism and absent circulating thyroglobulin due to TSH unresponsiveness and the first time that an inactivating mutation of the TSH receptor is described in the first extracellular loop.

Abstract
The molecular biology of follicular cell growth in thyroid nodules is still poorly understood. Because gain-of-function (activating) mutations of the thyroid-stimulating hormone receptor (TShR) and/or Gs alpha genes may confer TSh-independent growth advantage to neoplastic thyroid cells, we searched for somatic mutations of these genes in a series of hyperfunctioning and nonfunctioning follicular thyroid adenomas specifically selected for their homogeneous gross anatomy (single nodule in an otherwise normal thyroid gland). TShR gene mutations were identified by direct sequencing of exons 9 and 10 of the TShR gene in genomic DNA obtained from surgical specimens. Codons 201 and 227 of the Gs alpha gene were also analyzed. At histology, all hyperfunctioning nodules and 13 of 15 nonfunctioning nodules were diagnosed as follicular adenomas. Two nonfunctioning thyroid nodules, although showing a prevalent microfollicular pattern of growth, had histological features indicating malignant transformation (a minimally invasive follicular carcinoma and a focal papillary carcinoma). Activating mutations of the TShR gene were found in 12 of 15 hyperfunctioning follicular thyroid adenomas. In one hyperfunctioning adenoma, which was negative for TShR mutations, a mutation in codon 227 of the Gs alpha gene was identified. At variance with hyperfunctioning thyroid adenomas, no mutation of the TShR or Gs alpha genes was detected in nonfunctioning thyroid nodules. In conclusion, our findings clearly define a different molecular pathogenetic mechanism in hyperfunctioning and nonfunctioning follicular thyroid adenomas. Activation of the cAMP cascade, which leads to proliferation but maintains differentiation of follicular thyroid cells, typically occurs in hyperfunctioning thyroid adenomas. Oncogenes other than the TShR and Gs alpha genes are probably involved in nonfunctioning follicular adenomas.

Abstract
Similarities in the clinical presentation of panic disorder and temporal lobe epilepsy suggest that the two disorders are related and can lead to difficulties in a differential diagnosis. We describe the case of a young girl suffering from paroxysmal anxiety, derealization-depersonalization and autonomic symptoms, lasting from seconds to several minutes; these episodes were very frequent and disabling. The interictal EEGs and MRI were normal. After having diagnosed panic disorder based mainly on the duration of the attacks and the family history, a pharmacological treatment was started.

Abstract
We evaluated growth hormone (GH) secretion in 81 patients with Turner's syndrome (TS) (mean age 10.7+/-3.6 y) with respect to karyotype, auxological characteristics and growth response to GH treatment (1 IU/kg/wk). None of the patients had spontaneous puberty or had started replacement therapy with estrogens. Thirty-nine patients (48%) had monosomia 45X, 29 (36%) structural abnormalities of the X chromosome and 13 (16%) X mosaicism. Before the start of GH therapy, each patient underwent an evaluation of mean nocturnal GH concentration (MGHC) and 75 patients also underwent 2 pharmacological tests. MGHC of the TS patients did not differ from that of 29 prepubertal GH-deficient girls (GH peaks < 8 microg/l after pharmacological tests) and both groups were lower (p < 0.0001 and p < 0.0005, respectively) than MGHCs of 27 short normal girls (GH peak > 8 microg/l). MGHC of the patients with TS was negatively correlated (p < 0.001) with bodyweight excess (BWE) at multiple regression analysis. MGHC of the TS patients with BWE < 20% was significantly higher (p < 0.02) than that of the TS patients with BWE > 20%, but again did not differ from that of the GH-deficient patients and was lower (p < 0.001) than that of the short normal girls. MGHC did not significantly differ between the 3 groups subdivided according to karyotype. Forty-four percent of the TS patients showed GH responses to pharmacological tests < 8 microg/l. Height velocity SDS at first and second year of therapy was not influenced by MGHC levels, chronological or bone age, target height or BWE. In conclusion, spontaneous secretion in our patients with TS was lower than that of the short normal prepubertal girls and did not differ from that of GH-deficient subjects, even if we excluded overweight patients. The level of GH secretion was unable to predict GH response to treatment.

Abstract
The preferential association between Turner's syndrome and congenital heart defects (CHD) have been well known since the first description by Morgagni. There are few studies about the different cardiologic problems stemming from different chromosomal patterns of X monosomies. We reviewed a large series of 136 patients with Turner syndrome without cardiologic preselection, 29 of whom had some kind of CHD (21.5%). Partial anomalous pulmonary venous drainage (PAPVD; 2.9%), aortic valve disease (stenosis and/or incompetence) (AoVD; 5. 1%), aortic coarctation (AoCo; 4.4%), and bicuspid aortic valve (BicAo; 14.7%) are much more frequent in Turner's syndrome than in the normal population, with the difference being statistically highly significant. In our cases, only the 45, X subjects showed severe CHD and multiple lesions, whereas the X-ring pattern was associated with an elevated prevalence of BicAo. Patients with X-deletion showed no signs of congenital heart malformations. Eleven patients, all with 45, X pattern, and significant CHD, underwent cardiac surgery at a mean age of 7.7 +/- 5.3 years (range 7 days-18 years) without complications. At follow-up of 3-18 years (8.6 +/- 5. 2), we were unable to observe any type of evolution of the remaining untreated cardiovascular anomalies.

Abstract
We present a girl with lax, redundant skin, ectropion, bulbous nose, macrostomia, and absence of mammary glands. To our knowledge, she represents the fourth described case of Barber-Say Syndrome (BSS). BSS and ablepharon macrostomia syndrome (AMS) share common and distinctive clinical manifestations that involve the same structure of the skin and adnexa. We hypothesize that they may derive from a defective regulation of the same gene.

Abstract
Real-time ultrasonography was performed in 142 patients with Turner syndrome, aged 0.57 to 21 years, with different karyotypes (45,X [4896], X mosaicism [17%], and X structural abnormalities [35%]). Ovarian and uterine volumes were calculated and the data collected in a mixed longitudinal and cross-sectional mode. Thirty-eight patients were followed longitudinally during pubertal age (10 to 18 years bone age) for ovarian data. Patients with Turner syndrome were divided into two groups according to the presence or absence of detectable ovaries. Patients with Turner syndrome with detectable ovaries showed the first increase in ovarian volume at about 9 years of bone age; this increase was continuous and more evident only after 14 years of age and appeared later than in control subjects. When followed longitudinally during puberty, the ovaries showed a hormonal function in some cases. Girls with X mosaicism had the highest percentage of bilateral detectable ovaries and the greatest total ovarian volume; about 50% of them had spontaneous breast appearance and 38.5% had spontaneous menarche. They showed also the lowest gonadotropin levels, when bilateral ovaries were present during puberty. On the contrary, patients with the 45,X karyotype had the lowest percentage of detectable ovaries, ovarian volume, and spontaneous breast appearance. In our patients with Turner syndrome, uterine measures increased significantly with age and this was more evident in subjects with detectable ovaries after 13 years of bone age. Compared with control subjects, they showed significantly lower uterine measures, and patients with X mosaicism had greater and more progressive increments. In conclusion, pelvic ultrasonography in Turner syndrome is particularly useful in detecting ovaries and their possible increase in volume. These data, linked with karyotype pattern and gonadotropin levels, have prognostic value in predicting the future sexual development of these patients.
