Abstract
PURPOSE The integrated stress response (ISR) kinase PERK serves as a survival factor for both proliferative and dormant cancer cells. We aim to validate PERK inhibition as a new strategy to specifically eliminate solitary disseminated cancer cells (DCC) in secondary sites that eventually reawake and originate metastasis. EXPERIMENTAL DESIGN A novel clinical-grade PERK inhibitor (HC4) was tested in mouse syngeneic and PDX models that present quiescent/dormant DCCs or growth-arrested cancer cells in micro-metastatic lesions that upregulate ISR. RESULTS HC4 significantly blocks metastasis, by killing quiescent/slow-cycling ISRhigh, but not proliferative ISRlow DCCs. HC4 blocked expansion of established micro-metastasis that contained ISRhigh slow-cycling cells. Single-cell gene expression profiling and imaging revealed that a significant proportion of solitary DCCs in lungs were indeed dormant and displayed an unresolved ER stress as revealed by high expression of a PERK-regulated signature. In human breast cancer metastasis biopsies, GADD34 expression (PERK-regulated gene) and quiescence were positively correlated. HC4 effectively eradicated dormant bone marrow DCCs, which usually persist after rounds of therapies. Importantly, treatment with CDK4/6 inhibitors (to force a quiescent state) followed by HC4 further reduced metastatic burden. In HNSCC and HER2+ cancers HC4 caused cell death in dormant DCCs. In HER2+ tumors, PERK inhibition caused killing by reducing HER2 activity because of sub-optimal HER2 trafficking and phosphorylation in response to EGF. CONCLUSIONS Our data identify PERK as a unique vulnerability in quiescent or slow-cycling ISRhigh DCCs. The use of PERK inhibitors may allow targeting of pre-existing or therapy-induced growth arrested "persister" cells that escape anti-proliferative therapies.

Abstract
Chemical communication in terrestrial vertebrates is often built on complex blends, where semiochemical and structural compounds may form an integrated functional unit. In lizards, many species have specialized epidermal glands whose secretions are waxy, homogeneous blends of lipids and proteins, both active in communication. The intimate co-occurrence of such compounds allows us to hypothesize that they should undergo a certain degree of covariation, considering both their semiochemical role and the support-to-lipid function hypothesized for the protein fraction. In order to assess the occurrence and level of protein-lipid covariation, we compared the composition and complexity of the two fractions in the femoral gland secretions of 36 lizard species, combining phylogenetically-informed analysis with tandem mass spectrometry. We found the composition and complexity of the two fractions to be strongly correlated. The composition of the protein fraction was mostly influenced by the relative proportion of cholestanol, provitamin D3, stigmasterol, and tocopherol, while the complexity of the protein pattern increased with that of lipids. Additionally, two identified proteins (carbonic anhydrase and protein disulfide isomerase) increased their concentration as provitamin D3 became more abundant. Although our approach does not allow us to decrypt the functional relations between the proteinaceous and lipid components, nor under the semiochemical or structural hypothesis, the finding that the proteins involved in this association were enzymes opens up to new perspectives about protein role: They may confer dynamic properties to the blend, making it able to compensate predictable variation of the environmental conditions. This may expand the view about proteins in the support-to-lipid hypothesis, from being a passive and inert component of the secretions to become an active and dynamic one, thus providing cues for future research.

Abstract
Abstract
The integrated stress response (ISR) is an adaptive signaling pathway that cells utilize to respond to a wide range of extrinsic and intrinsic stresses, which are important for tumorigenesis. Activation of ISR is suggested to play a dual role in cell fate decisions. While the ISR promotes survival, prolonged activation of ISR induces apoptosis. We are developing HC-7366, a first-in-class, first-in-human GCN2 activator, and are currently evaluating it in a phase 1 clinical trial in solid tumors (NCT05121948). In this study, we present the characterization of the antitumor effects of HC-7366 in solid tumors.
In vivo efficacy studies using HC-7366 montherapy showed significant tumor growth inhibition (TGI%) in preclinical cancer models of colorectal (78-95%), head and neck (33% regression), sarcoma (80%) and prostate (65%). HC-7366 activated the ISR in tumors from treated mice as evidenced by induction of the ATF4 target genes ASNS and PSAT1. Additionally, HC-7366 induced the proapoptotic protein PUMA and reduced HIF1⍺ and HIF2⍺ levels. Furthermore, HC-7366 showed significant benefit in colorectal models when combined with DC101 (anti-VEGFR2 antibody), 5-fluorouracil (chemotherapy), alpelisib (PI3Kα inhibitor), or trametinib (MEK1/2 inhibitor). Using GCN2 CRISPR-knockout cells, we confirmed that the HC-7366 mediated reduction of cell growth and induction of ISR markers was dependent on GCN2. We performed multi-omics analyses to further understand the mechanism of action. Metabolomics analysis of tumors treated with HC-7366 revealed that HC-7366 altered several metabolites involved in amino acid metabolism, oxidative stress, the urea cycle, and pyrimidine biosynthesis. Additionally, proteomics analysis showed that HC-7366 significantly reduced proteins involved in oxidative phosphorylation. Analysis of the transcriptome in tumors from treated mice demonstrated that HC-7366 reduced the activity of HIF and E2F1-driven transcription, including expression of metaphase-anaphase transition genes, consistent with decreased Ki67 staining in tumors. ATF4 and JUN transcriptional activity was enhanced with HC-7366 treatment consistent with activation of ISR. Collectively, our in vitro and in vivo results demonstrate that HC-7366 is a potent GCN2 activator with strong antitumor activity across multiple solid tumor models as a monotherapy or in combination with standard of care agents.

Abstract
Timely detection of severe infratentorial hemorrhage in neonates is crucial, especially in case of life-threatening brain stem compression and/or acute obstructive hydrocephalus, which need lifesaving neurosurgical intervention. Although the detection of infratentorial hemorrhage by ultrasound scanning is often considered as difficult, the use of additional acoustic windows and recognition of characteristic ultrasound features facilitate early diagnosis. In this case series, we report on newborns with severe, symptomatic infratentorial hemorrhage detected primarily by cranial ultrasound. We demonstrate the characteristic ultrasound features present in all cases and discuss how ultrasound diagnosis contributed to early diagnosis and treatment.

Abstract
INTRODUCTION Cri-du-Chat Syndrome (CdCS) is a genetic condition due to deletions showing different breakpoints encompassing a critical region on the short arm of chromosome 5, located between p15.2 and p15.3, first defined by Niebuhr in 1978. The classic phenotype includes a characteristic cry, peculiar facies, microcephaly, growth retardation, hypotonia, speech and psychomotor delay and intellectual disability. A wide spectrum of clinical manifestations can be attributed to differences in size and localization of the 5p deletion. Several critical regions related to some of the main features (such as cry, peculiar facies, developmental delay) have been identified. The aim of this study is to further define the genotype-phenotype correlations in CdCS with particular regards to the specific neuroradiological findings. PATIENTS AND METHODS Fourteen patients with 5p deletions have been included in the present study. Neuroimaging studies were conducted using brain Magnetic Resonance Imaging (MRI). Genetic testing was performed by means of comparative genomic hybridization (CGH) array at 130 kb resolution. RESULTS MRI analyses showed that isolated pontine hypoplasia is the most common finding, followed by vermian hypoplasia, ventricular anomalies, abnormal basal angle, widening of cavum sellae, increased signal of white matter, corpus callosum anomalies, and anomalies of cortical development. Chromosomal microarray analysis identified deletions ranging in size from 11,6 to 33,8 Mb on the short arm of chromosome 5. Then, we took into consideration the overlapping and non-overlapping deleted regions. The goal was to establish a correlation between the deleted segments and the neuroradiological features of our patients. CONCLUSIONS Performing MRI on all the patients in our cohort, allowed us to expand the neuroradiological phenotype in CdCS. Moreover, possible critical regions associated to characteristic MRI findings have been identified.

Abstract
Cerebellar hemorrhage (CBH) is a frequent complication of preterm birth and may play an important and under-recognized role in neurodevelopment outcome. Association between CBH size, location, and neurodevelopment is still unknown. The main objective of this study was to investigate neurodevelopmental outcome at 2 years of age in a large number of infants with different patterns of CBH. Of preterm infants (≤ 34 weeks) with known CBH, perinatal factors, neuro-imaging findings, and follow-up at 2 years of age were retrospectively collected. MRI scans were reassessed to determine the exact size, number, and location of CBH. CBH was divided into three groups: punctate (≤ 4 mm), limited (> 4 mm but < 1/3 of the cerebellar hemisphere), or massive (≥ 1/3 of the cerebellar hemisphere). Associations between pattern of CBH, perinatal factors, and (composite) neurodevelopmental outcome were assessed. Data of 218 preterm infants with CBH were analyzed. Of 177 infants, the composite outcome score could be obtained. Forty-eight out of 119 infants (40%) with punctate CBH, 18 out of 35 infants (51%) with limited CBH, and 18 out of 23 infants (78%) with massive CBH had an abnormal composite outcome score. No significant differences were found for the composite outcome between punctate and limited CBH (P = 0.42). The risk of an abnormal outcome increased with increasing size of CBH. Infants with limited CBH have a more favorable outcome than infants with massive CBH. It is therefore important to distinguish between limited and massive CBH.

Abstract
The successful production of recombinant enzymes by tobacco transplastomic plants must maintain compatibility of the heterologous enzyme with chloroplast metabolism and its long-time enzyme stability. Based on previous reports, it has been taken for granted that following biolistic-transformation, homoplasticity could be obtained from the initially heteroplastic state following successive rounds of selection in the presence of the selection agent. However, several studies indicated that this procedure does not always ensure the complete elimination of unmodified wild-type plastomes. The present study demonstrates that CelK1 transplastomic plants, which were photosyntetically as active as untransformed ones, remain heteroplastomic even after repeated selection steps and that this state does not impair the relatively high-level production of the recombinant enzyme. In fact, even in the heteroplastomic state, the recombinant protein represented about 6% of the total soluble proteins (TSP). Moreover, our data also show that, while the recombinant endoglucanase undergoes phosphorylation, this post-translation modification does not have any significant impact on the enzymatic activity. Biomass storage might be required whenever the enzyme extraction process could not be performed immediately following the harvest of tobacco mature plants. In this respect, we have observed that enzyme activity in the detached leaves stored at 4 °C is maintained up to 20 weeks without significant loss of activity. These findings may have major implications in the future of chloroplast genetic engineering-based molecular farming to produce industrial enzymes in transplastomic plants.

Abstract
We aimed to provide comprehensive protocols and promote effective management of pregnant women with gynecological cancers. New insights and more experience have been gained since the previous guidelines were published in 2014. Members of the International Network on Cancer, Infertility and Pregnancy (INCIP), in collaboration with other international experts, reviewed existing literature on their respective areas of expertise. Summaries were subsequently merged into a manuscript that served as a basis for discussion during the consensus meeting. Treatment of gynecological cancers during pregnancy is attainable if management is achieved by collaboration of a multidisciplinary team of health care providers. This allows further optimization of maternal treatment, while considering fetal development and providing psychological support and long-term follow-up of the infants. Nonionizing imaging procedures are preferred diagnostic procedures, but limited ionizing imaging methods can be allowed if indispensable for treatment plans. In contrast to other cancers, standard surgery for gynecological cancers often needs to be adapted according to cancer type and gestational age. Most standard regimens of chemotherapy can be administered after 14 weeks gestational age but are not recommended beyond 35 weeks. C-section is recommended for most cervical and vulvar cancers, whereas vaginal delivery is allowed in most ovarian cancers. Breast-feeding should be avoided with ongoing chemotherapeutic, endocrine or targeted treatment. More studies that focus on the long-term toxic effects of gynecologic cancer treatments are needed to provide a full understanding of their fetal impact. In particular, data on targeted therapies that are becoming standard of care in certain gynecological malignancies is still limited. Furthermore, more studies aimed at the definition of the exact prognosis of patients after antenatal cancer treatment are warranted. Participation in existing registries (www.cancerinpregnancy.org) and the creation of national tumor boards with multidisciplinary teams of care providers (supplementary Box S1, available at Annals of Oncology online) is encouraged.

Abstract
A total of 1095 patients with operable breast cancer and en-rolled in a randomized clinical trial were analysed for estrogen (ER) and progesterone (PgR) receptor content of their primary tumor, and the relationships between steroid receptor status and several epidemiologic characteristics were studied. The proportion of ER+ and median ER levels increased with age: compared to women younger than 40, those aged 66 or more were approximately three times more likely to have an ER+ tumor (OR = 3.0, 95% C.I. = 1.6–5.7). This difference tended to be more marked after comparison between patients with ER > 100 fmol/mg protein and ER- within the same age groups: OR = 7.04, 95 % C.I. = 2.89–17.12. No association emerged between age and PgR. ER status and concentrations were independent of menopausal status after adjustment for age, whereas the proportion of PgR+ and PgR levels were significantly lower in postmenopausal patients of the same age. The distribution of ER and PgR profiles was similar in relation to family history of breast cancer, reproductive events and other selected epidemiologic characteristics of the patients.

Abstract
Botanicals are widely consumed all over the world for health purposes, with increased usage in the general population, in many different types of products, including foods and plant food supplements. Several reports support for the beneficial effects of botanicals against gastrointestinal inflammation. However, no studies regarding the anti-inflammatory activity in the gastrointestinal tract of red vine leaves have been reported so far. The present work investigates the biological activity of Vitis vinifera L. water extract (VVWE) from dried leaves in two in vitro models of gastric and intestinal inflammation. The extract was characterized by a validated HPLC-DAD method, and tested on human epithelial gastric (AGS) and intestinal (Caco-2) cells with the aim to investigate the inhibitory effect on IL-8 secretion and promoter activity, before and after in vitro gastric or gastrointestinal digestion. Our results show that the water extract from red vine leaves inhibits TNFα-induced IL-8 secretion and expression in human gastric epithelial cells; the effect should be maintained, although to a lesser extent, after gastric digestion. In contrast, the effect after intestinal digestion is dramatically decreased since degradation of the active components in the gut does not allow the extract to efficiently counteract TNFα or IL-1β induced IL-8 expression and the NF-κB pathway. The main molecular target of VVWE at the gastric level includes TNFα-induced activation of NF-κB and occurs at concentrations easily reachable after PFS consumption based on red vine leaf water extract as the ingredient. Our findings suggest that PFS containing water extracts from Vitis vinifera L. leaves could be useful to inhibit/attenuate gastric inflammation inhibiting IL-8 secretion and expression through impairment of the NF-κB pathway.

Abstract
We report a small-angle neutron scattering study of liquid water sorption in Nafion membranes. The swelling of hydrophilic domains was measured on the nanoscale by combining in situ time-resolved and long-term static experiments, yielding kinetic curves recorded over an unprecedented time scale, from hundreds of milliseconds to several years. At low water content, typically below 5 water molecules per ionic group, a limited subdiffusive regime was observed and ascribed to nanoconfinement and local interactions between charged species and water molecules. Further ultrafast and thermally activated swelling due to massive liquid water sorption was observed and analyzed by using Fick's equation. The extracted mutual water diffusion coefficients are in good agreement with pulsed field gradient NMR self-diffusion coefficient values, evidencing a water diffusion-driven process due to concentration gradients within the Nafion membrane. Finally, after completion of the ultrafast regime, the kinetic swelling curves exhibit a remarkable long-term behavior scaling as the logarithm of time, showing that the polymer membrane can continuously accommodate additional water molecules upon hydration stress. The present nanoscale kinetics results provide insights into the vapor-versus-liquid sorption mechanisms, the nanostructure of Nafion, and the role of polymer reorganization modes, highlighting that the membrane can never reach a steady state.

Abstract
AIM Thyroiditis is often associated with nodules based on the Bethesda classification system, and the presence of thyroiditis can make thyroid surgery difficult using both conventional techniques and minimally invasive videoassisted approaches (MIVAT). METHODS We analyzed 326 patients who underwent total thyroidectomy in 2012. We collected all data in dedicated database. The patients were divided in 4 groups: group 1 no affected by thyroiditis, group 2 affected by thyroiditis, group 3 only histological diagnosis of thyroiditis, group 4all patients affected by thyroiditis. RESULTS Group 1 included 201 cases, group 2 included 64 patients, group 3 included 61 patients. No statistically significant difference between group 2 and 3 about Ultrasound (US) examination. Statistically significant difference in incidence of "THYR 3-4" between group 1 and group 4. No differences in MIVAT vs. Conventional group. CONCLUSION US examination of the thyroid is essential for the diagnostic study of the gland also in the selection of a surgical approach. Thyroiditis is a relative contraindication to MIVAT but the experience of the endocrine surgeon is the most important factor to reduce intra and postoperative complications together a correct collaboration in multidisciplinart endocrinological team.

Abstract
Oncogene-induced reactive oxygen species (ROS) have been proposed to be signaling molecules that mediate proliferative cues. However, ROS may also cause DNA damage and proliferative arrest. How these apparently opposite roles can be reconciled, especially in the context of oncogene-induced cellular senescence, which is associated both with aberrant mitogenic signaling and DNA damage response (DDR)-mediated arrest, is unclear. Here, we show that ROS are indeed mitogenic signaling molecules that fuel oncogene-driven aberrant cell proliferation. However, by their very same ability to mediate cell hyperproliferation, ROS eventually cause DDR activation. We also show that oncogenic Ras-induced ROS are produced in a Rac1 and NADPH oxidase (Nox4)-dependent manner. In addition, we show that Ras-induced ROS can be detected and modulated in a living transparent animal: the zebrafish. Finally, in cancer we show that Nox4 is increased in both human tumors and a mouse model of pancreatic cancer and specific Nox4 small-molecule inhibitors act synergistically with existing chemotherapic agents.

Abstract
BACKGROUND Research conducted in the past decade challenges the traditional view that essential tremor (ET) is characterised exclusively by movement disorder, and increasingly shows that these patients have deficits in cognitive and behavioural functioning. The available evidence suggests that this impairment might arise from dysfunction in either the fronto-subcortical or cortico-cerebellar circuits. Although abnormalities in the fronto-subcortical circuits could imply difficulty in lying, no study has investigated deception in patients with ET. AIMS To examine the cognitive functions regulating deception in patients with ET, we used a computerised task, the Guilty Knowledge Task (GKT). We also tested a group of patients with Parkinson's disease (PD), a disease associated with a known difficulty in lie production, and a group of healthy subjects (HS). RESULTS In the GKT for deception, patients with ET responded less accurately than HS (p=0.014) but similarly to patients with PD (p=0.955). No differences between groups were found in truthful responses (p=0.488). CONCLUSIONS Besides confirming impaired deception in patients with PD, our results show a lie production deficit in patients with ET also. These findings suggest that difficulty in lying is an aspecific cognitive feature in movement disorders characterised by fronto-subcortical circuit dysfunction, such as PD and ET. Current knowledge along with our new findings in patients with ET--possibly arising from individually unrecognised extremely mild, cognitive difficulties--should help in designing specific rehabilitative programmes to improve cognitive and behavioural disturbances in patients.

Abstract
Steroids have long been used to improve a number of clinical conditions because of their role in reducing inflammatory responses, but their use has always been limited because of their possible long-term side effects. The aim of this review is to establish whether steroids can have a positive effect on the outcome of some pediatric upper respiratory tract infections. We used PubMed to select all of the studies on topical or systemic steroids, and their therapeutic use in children with rhinosinusitis (RS), acute otitis media (AOM), otitis media with effusion (OME), acute pharyngitis (AP), or periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA), published over the last 15 years. Although a generally significant improvement in signs and symptoms has been observed with the use of intranasal steroids in children with RS, it is not clear which molecule should be recommended, how long treatment should be continued, or whether the benefits are limited to allergic children. No high-quality studies on the use of topical or systemic steroids in AOM have been carried out, and the results of studies of OME are controversial. The potential positive effects of steroids in children with AP are too slight to justify their use, and their possible adverse effects (particularly in the case of repeated administration) have not been clearly evaluated. Oral corticosteroids seem to be effective in resolving the symptoms of PFAPA, although they do not prevent future fever cycles. These findings show that further randomised and controlled studies are required in order to approach upper respiratory tract infections correctly and avoid the risks associated with frequent steroid use.

Abstract
Respiratory failure in the premature infants remains a difficult challenge. An alternative to the use of nasal continuous positive airway pressure (NCPAP) as a non-invasive modality to support respiratory distress in premature infants has been the recent introduction of high flow nasal cannula (HFNC) devices in many neonatal units. There has been increased use of HFNC presumably because of anecdotal reports and experience that it is easy to use, and well tolerated by the infants, while experiencing decreased nasal septumerosion. The paucity of evidence regarding its efficacy and safety, would support a caution approach to the use of HFNC. Particular concern has focused on the imprecise regulation and generation of pressure that may occur at higher flows especially in the smallest of infants.

Abstract
The human ZC3HAV1 gene encodes an antiviral protein. The longest splicing isoform of ZC3HAV1 contains a C-terminal PARP-like domain, which has evolved under positive selection in primates. We analyzed the evolutionary history of this same domain in humans and in Pan troglodytes. We identified two variants that segregate in both humans and chimpanzees; one of them (rs3735007) does not occur at a hypermutable site and accounts for a nonsynonymous substitution (Thr851Ile). The probability that the two trans-specific polymorphisms have occurred independently in the two lineages was estimated to be low (P = 0.0054), suggesting that at least one of them has arisen before speciation and has been maintained by selection. Population genetic analyses in humans indicated that the region surrounding the shared variants displays strong evidences of long-standing balancing selection. Selection signatures were also observed in a chimpanzee population sample. Inspection of 1000 Genomes data confirmed these findings but indicated that search for selection signatures using low-coverage whole-genome data may need masking of repetitive sequences. A case–control study of more than 1,000 individuals from mainland Italy indicated that the Thr851Ile SNP is significantly associated with susceptibility to multiple sclerosis (MS) (odds ratio [OR] = 1.47, 95% confidence intervals [CI]: 1.08–1.99, P = 0.011). This finding was confirmed in a larger sample of 4,416 Sardinians cases/controls (OR = 1.18, 95% CI: 1.037–1.344, P = 0.011), but not in a population from Belgium. We provide one of the first instances of human/chimpanzee trans-specific coding variant located outside the major histocompatibility complex region. The selective pressure is likely to be virus driven; in modern populations, this variant associates with susceptibility to MS, possibly via the interaction with environmental factors.

Abstract
Preterm labor is the final common pathway of different complications of pregnancy and despite substantial progress in antenatal care, preterm birth remains a major health issue across the globe. Preterm deliveries in the larger group of spontaneous preterm labor or preterm prelabor rupture of membranes (PPROM) are often associated with intrauterine chorioamnionitis. Current evidence underlines the role of "inflammatory" and "placental dysfunction" disorders in pregnancy on prematurity-associated morbidity, particularly respiratory outcome.

Abstract
BACKGROUND Delayed meconium passage, typical of premature newborns, is a predisposing condition for bowel perforation with a significant risk of morbidity and mortality. AIM OF THE STUDY A retrospective study was undertaken to verify the entity of the disease, assess the average time to meconium passage in a neonatal population of very low birth weight (VLBW) infants, and identify associated risk factors. METHODS The time of first stool passage was studied in 110 VLBW infants (weighing less than 1500 g at birth). Their perinatal features, clinical course, and treatment were reviewed and studied retrospectively. RESULTS Delayed meconium passage was recorded in 81% of this group. Patent ductus arteriosus, mechanical ventilation and uteroplacental insufficiency were significantly associated with delayed passage. An inverse relationship between gestational age, birth weight and meconium passage was found. Bowel perforation occurred in 4.5% of this neonatal population with a mortality of 50%. CONCLUSIONS In very low birth weight infants delay in the passage of the first stool is common. Perforation in these patients may represent a fatal event, and procedures such as daily rectal enemas, which can prevent this complication, must be applied.

Abstract
The impact and consequences of damage generation into genomic DNA, especially in the form of DNA double-strand breaks, and of the DNA-damage response (DDR) pathways that are promptly activated, have been elucidated in great detail. Most of this research, however, has been performed on proliferating, often cancerous, cell lines. In a mammalian body, the majority of cells are terminally differentiated (TD), and derives from a small pool of self-renewing somatic stem cells. Here, we comparatively studied DDR signaling and radiosensitivity in neural stem cells (NSC) and their TD-descendants, astrocytes - the predominant cells in the mammalian brain. Astrocytes have important roles in brain physiology, development and plasticity. We discovered that NSC activate canonical DDR upon exposure to ionizing radiation. Strikingly, astrocytes proved radioresistant, lacked functional DDR signaling, with key DDR genes such as ATM being repressed at the transcriptional level. Nevertheless, astrocytes retain the expression of non-homologous end-joining (NHEJ) genes and indeed they are DNA repair proficient. Unlike in NSC, in astrocytes DNA-PK seems to be the PI3K-like protein kinase responsible for γH2AX signal generation upon DNA damage. We also demonstrate the lack of functional DDR signaling activation in vivo in astrocytes of irradiated adult mouse brains, although adjacent neurons activate the DDR.

Abstract
BACKGROUND Right laparoscopic colectomy was introduced to colorectal surgery later than the left colon procedure. Three-trocar laparoscopy has already been used successfully in the treatment of gynecological cancers. In the present study, we aimed to analyze the feasibility of performing an associated gynecological procedure following abdominal laparoscopic exploration and to evaluate the suitability of laparoscopic right colectomy for treating elderly patients. METHODS We conducted a review of prospectively collected data on 100 consecutive patients who were treated with right laparoscopic colectomy using three trocars from January 2005 to April 2010. We recorded the patients' age (<70 or > 70 years), ASA status, body mass index (BMI), pain on postoperative days 1 and 2 (POD 1, 2), nodes retrieved, laparotomic conversion, mean operative time, time to intestinal recovery, and length of postoperative stay. RESULTS All subjects were treated for cancer. Conversion to the laparotomic procedure was performed in 13/100, with no difference in terms of age. Operative time was longer for laparotomic conversion (p <0.05), with a longer postoperative stay. Elderly patients had higher ASA scores (p < 0.005); age did not influence the conversion rate or BMI status. Pain on POD 1 and 2 differed between the laparotomic and laparoscopic groups (p <0.0001). Associated procedures were performed in five subjects (3 oophorectomy and 2 cholecystectomy). CONCLUSIONS Laparoscopy using the three-trocar technique is a safe procedure for treating colon cancer, including in elderly patients, and enables associated gynecological laparoscopic procedures to be performed.

Abstract
BACKGROUND/PURPOSE Anorectal malformations (ARM) are a spectrum of defects ranging from the very minor ones, with an excellent functional prognosis, to those that are more complex, often associated with other anomalies, difficult to manage and with a poor functional outcome. A significant number of these children suffer from fecal and urinary incontinence despite major advances in the management of ARM patients have significantly improved the quality of life. The role of sacrovertebral anomalies/dysraphism (SD) and neurospinal cord anomalies/dysraphism (ND) associated with ARM on the continence of these patients is still controversial. The authors made a review of their experience in a period of 5 years, focusing on the role of neurospinal cord anomalies in patients with ARM. MATERIALS At colorectal clinic of our department of pediatric surgery 215 patients who underwent a procedure of posterior sagittal anorectoplasty for ARM are followed-up in a multidisciplinary clinic. Among them 60 patients with either SD or ND were documented. In 37 patients the anomaly involved the spinal cord (ND). 12 of these 37 patients underwent neurosurgical treatment and 25 were managed conservatively. Data collected from their follow-up were analyzed and compared, focusing on their bowel and urinary continence. RESULTS All 37 patients acquired regular bowel movements with an appropriate bowel management according to Peña's protocols. Urinary incontinence required clean intermittent catheterization in four cases. None of the patients who did not receive neurosurgical treatment developed acute complications due to the progression of the neurospinal anomaly, like acute urinary retention, orthopedic and motility problems or acute hydrocephalus. From literature review we were unable to find good evidence that the presence of ND worsens the functional prognosis of patients with ARM. We were also unable to find convincing evidence to support the practice of prophylactic neurosurgical procedures. CONCLUSIONS The present study supports the theory that for ARM patients the prognosis in terms of continence depends mainly on the type of malformation and is not complicated by the association with ND. In our series neurosurgical treatments did not have any effect in improving the continence of ARM patients and a conservative management of ND did not expose the patients to the sequelae of progressive deterioration, reported elsewhere, requiring rescue neurosurgery. We believe that the correct practice of pediatric surgeons following-up ARM patients is a protocol which includes appropriate investigations to detect the presence of a SD or ND and, once these entities are detected, it is mandatory to manage the patient with a multidisciplinary team, where a conservative non-operative management is initially justified and advocated in the absence of neurosensorymotor symptoms.

Abstract
The human TRIM5 genes encodes a retroviral restriction factor (TRIM5α). Evolutionary analyses of this gene in mammals have revealed a complex and multifaceted scenario, suggesting that TRIM5 has been the target of exceptionally strong selective pressures, possibly exerted by recurrent waves of retroviral infections. TRIM5 displays inter-individual expression variability in humans and high levels of TRIM5 mRNA have been associated with a reduced risk of HIV-1 infection. We resequenced TRIM5 in chimpanzees and identified two polymorphisms in intron 1 that are shared with humans. Analysis of the gene region encompassing the two trans-specific variants in human populations identified exceptional nucleotide diversity levels and an excess of polymorphism compared to fixed divergence. Most tests rejected the null hypothesis of neutral evolution for this region and haplotype analysis revealed the presence of two deeply separated clades. Calculation of the time to the most recent common ancestor (TMRCA) for TRIM5 haplotypes yielded estimates ranging between 4 and 7 million years. Overall, these data indicate that long-term balancing selection, an extremely rare process outside MHC genes, has maintained trans-specific polymorphisms in the first intron of TRIM5. Bioinformatic analyses indicated that variants in intron 1 may affect transcription factor-binding sites and, therefore, TRIM5 transcriptional activity. Data herein confirm an extremely complex evolutionary history of TRIM5 genes in primates and open the possibility that regulatory variants in the gene modulate the susceptibility to HIV-1.

Abstract
The perinatal ischemic stroke is defined as "a group of heterogenous conditions with a focal disruption of cerebral flow secondary to an arterial or a venous thrombosis or embolization between the 20 week of foetal life through the 28 post-natal day". Three subgroups are identified: arterial ischemic stroke (AIS), cerebral sinovenous thrombosis (CSVT) and haemorragic infarct. Many strokes are detected in the neonatal period due to early onset seizures, although symptoms can be more subtle leading to a significant delay in the diagnosis. MRI-DWI remains the best tool for a correct diagnosis, extension of the lesion and suggestion of timing. Lesions detected in utero or at early neonatal imaging with signs of tissue loss are considered "foetal stroke". The "neonatal stroke", with the symptoms in the first 4 days, shows the typical abnormalities of the acute phase evolving later in a white matter loss. The AIS shows the ischemic area of restriction at the early DWI in a arterial territory, mainly the middle cerebral artery. The MR-Venogram is useful in the CVST to detect the thrombus in a sinovenous vessel and the potentially associated lesion, such as intraventricular haemorrage and parenchymal oedema. The extension of the lesion and the involvement of the basal ganglia and thalami have a negative prognostic value for the development of hemiplegia especially in the presence of abnormal PLIC. An early diagnosis.

Abstract
e16014 Background: Long-term effects of a combined approach of transurethral resection (TUR) plus chemotherapy (CT) and pelvic radiotherapy (RT) in terms of bladder preservation, survival, QOL are largely unknown. Moreover we investigated whether p53, Ki67, bcl-2, c-erbB-2 protein expression predict the achievement of a complete response (CR). Methods: From March 1994 to June 2000, 75 pts with muscle invasive BC were treated with a bladder sparing approach including an initial TUR, 3 cycles of CT (cisplatin + 5- FU) alternating with pelvic RT (40 Gy). At the response evaluation, pts with biopsy proven residual disease were considered incomplete responders (IR) and underwent immediate cystectomy. Pts with CR were treated with two additional CT cycles plus a bladder RT boost (20- 24 Gy). Paraffin embedded blocks of the primary tumors were collected and Ki67, p53, bcl-2 and c-erbB-2 protein expression were evaluated in a blind fashion. The Expanded Prostate Cancer Index Composite (EPIC) scores for urinary function, (especially storage, voiding symptoms and bowel function) was used to explore QOL in bladder preserved and compared with a group of matched patients treated by radical cystectomy only. Results: Median age was 67 yrs (range 42–80); T2a-T2b: 42%; T3a-T3b: 47%; T4a: 11%; G3: 88%; hydronephrosis: 32%. Overall, 56 (74.7%) pts achieved a CR and the achievement of a CR was significantly related to lower T stage (p= 0.002), high Ki67 (p=0.001), absence of hydronephrosis (p= 0.007) and high p53 overexpression (p=0.007). Multivariate analysis showed that only a low T stage (p=0.002) and high p53 expression (p=0.043) predict the obtaining of a CR. At 5 years of follow-up, 44 (59%) were alive and in 33 of them (75%) bladder was preserved; after 10-years 28 (37.3%) were alive and in 23 of them (82%) bladder was preserved. Analysis of QOL scores is ongoing. Conclusions: This approach induces a long term survival similar to radical cystectomy with a high rate of bladder preservation and represents a valid treatment for muscle invasive BC. Overexpression of p53 is a predictive marker for the obtaining of CR and for bladder preservation. No significant financial relationships to disclose.

Abstract
The aim of the study was to measure the difference between the set continuous positive airway pressure (CPAP) value and the pharyngeal pressure reading during CPAP in premature infants with mild respiratory distress syndrome, using two different devices: hood CPAP and the conventional nasal system. The preliminary results suggest that hood CPAP may produce more stable pharyngeal pressure than the conventional nasal device.
