Abstract
5-Hydroxytryptamine receptor 1E (5-HTR1E) is reported to activate cyclic AMP (cAMP) and extracellular-signal related kinases (ERK) pathways via its ligands and binding partners, but the detailed mechanism underlying the serotonin-induced 5-HTR1E signaling is still not known. In the present study, we determined the cellular regulators of ERK and cAMP signaling pathways in response to serotonin-induced 5-HTR1E activation in 5-HTR1E overexpressing HEK293 cells. We found that Pertussis Toxin (PTX) treatment completely reversed the effect of serotonin-5-HTR1E mediated signaling on cAMP and ERK pathways, confirming the involvement of a Gαi-linked cascade. We also observed that Gβγ and Gq were not associated with 5-HTR1E activation, while blocking protein kinase A (PKA) inhibited ERK signaling only, and had no effect on cAMP. Additionally, serotonin-stimulated ERK1/2 phosphorylation was similar in 5-HTR1E overexpressing, β-arrestin-deficient HEK293 cells and is solely dependent on G protein signaling. siRNA mediated gene knockdown studies in SH-SY5Y cells revealed that the inhibition of 5-HTR1E reduced the expression of cMyc, Cyclin D1, Cyclin E and BCL2 genes which are related to cell cycle regulation and survival. MTT assays showed that 5-HTR1E knockdown in SHSY-5Y and U118 cells inhibited cell survival significantly. In addition to the signaling mechanism, we also performed RNA-seq analysis in 5-HTR1E overexpressing HEK293 cells and found that 5-HTR1E can regulate the expression of Receptor activity modifying protein 1 (RAMP1), Nuclear receptor 1 (NR4A1) and other Cyclin genes. These findings indicate that serotonin interaction with 5-HTR1E receptor simultaneously activates cAMP and ERK pathway in HEK293 cells and its expression is important for cell survival.

Abstract
GRTH/DDX25 is a testis-specific DEAD-box family of RNA helicase, which plays an essential role in spermatogenesis and male fertility. There are two forms of GRTH, a 56 kDa non-phosphorylated form and a 61 kDa phosphorylated form (pGRTH). GRTH-KO and GRTH Knock-In (KI) mice with R242H mutation (lack pGRTH) are sterile with a spermatogenic arrest at step 8 of spermiogenesis due to failure of round spermatids (RS) to elongate. We performed mRNA-seq and miRNA-seq analysis on RS of WT, KI, and KO to identify crucial microRNAs (miRNAs) and mRNAs during RS development by establishing a miRNA-mRNA network. We identified increased levels of miRNAs such as miR146, miR122a, miR26a, miR27a, miR150, miR196a, and miR328 that are relevant to spermatogenesis. mRNA-miRNA target analysis on these DE-miRNAs and DE-mRNAs revealed miRNA target genes involved in ubiquitination process (Ube2k, Rnf138, Spata3), RS differentiation, and chromatin remodeling/compaction (Tnp1/2, Prm1/2/3, Tssk3/6), reversible protein phosphorylation (Pim1, Hipk1, Csnk1g2, Prkcq, Ppp2r5a), and acrosome stability (Pdzd8). Post-transcriptional and translational regulation of some of these germ-cell-specific mRNAs by miRNA-regulated translation arrest and/or decay may lead to spermatogenic arrest in KO and KI mice. Our studies demonstrate the importance of pGRTH in the chromatin compaction and remodeling process, which mediates the differentiation of RS into elongated spermatids through miRNA-mRNA interactions.

Abstract
Medial ganglionic eminence (MGE)-derived parvalbumin (PV)+, somatostatin (SST)+and Neurogliaform (NGFC)-type cortical and hippocampal interneurons, have distinct molecular, anatomical, and physiological properties. However, the molecular mechanisms regulating their maturation remain poorly understood. Here, via single-cell transcriptomics, we show that the obligate NMDA-type glutamate receptor (NMDAR) subunit gene Grin1 mediates transcriptional regulation of gene expression in specific subtypes of MGE-derived interneurons, leading to altered subtype abundances. Notably, MGE-specific early developmental Grin1 loss results in a broad downregulation of diverse transcriptional, synaptogenic and membrane excitability regulatory programs in the juvenile brain. These widespread gene expression abnormalities mirror aberrations that are typically associated with neurodevelopmental disorders. Our study hence provides a road map for the systematic examination of NMDAR signaling in interneuron subtypes, revealing potential MGE-specific genetic targets that could instruct future therapies of psychiatric disorders.

Abstract
Reversible modification of proteins with linkage-specific ubiquitin chains is critical for intracellular signaling. Information on physiological roles and underlying mechanisms of particular ubiquitin linkages during human development are limited. Here, relying on genomic constraint scores, we identify 10 patients with multiple congenital anomalies caused by hemizygous variants in OTUD5, encoding a K48/K63 linkage-specific deubiquitylase. By studying these mutations, we find that OTUD5 controls neuroectodermal differentiation through cleaving K48-linked ubiquitin chains to counteract degradation of select chromatin regulators (e.g., ARID1A/B, histone deacetylase 2, and HCF1), mutations of which underlie diseases that exhibit phenotypic overlap with OTUD5 patients. Loss of OTUD5 during differentiation leads to less accessible chromatin at neuroectodermal enhancers and aberrant gene expression. Our study describes a previously unidentified disorder we name LINKED (LINKage-specific deubiquitylation deficiency-induced Embryonic Defects) syndrome and reveals linkage-specific ubiquitin cleavage from chromatin remodelers as an essential signaling mode that coordinates chromatin remodeling during embryogenesis.

Abstract
The website and database https://snengs.nichd.nih.gov provides RNA sequencing data from multi-species analysis of the pineal glands from zebrafish (Danio rerio), chicken (White Leghorn), rat (Rattus novegicus), mouse (Mus musculus), rhesus macaque (Macaca mulatta), and human (Homo sapiens); in most cases, retinal data are also included along with results of the analysis of a mixture of RNA from tissues. Studies cover day and night conditions; in addition, a time series over multiple hours, a developmental time series and pharmacological experiments on rats are included. The data have been uniformly re-processed using the latest methods and assemblies to allow for comparisons between experiments and to reduce processing differences. The website presents search functionality, graphical representations, Excel tables, and track hubs of all data for detailed visualization in the UCSC Genome Browser. As more data are collected from investigators and improved genomes become available in the future, the website will be updated. This database is in the public domain and elements can be reproduced by citing the URL and this report. This effort makes the results of 21st century transcriptome profiling widely available in a user-friendly format that is expected to broadly influence pineal research.

Abstract
Many areas of research suffer from poor reproducibility, particularly in computationally intensive domains where results rely on a series of complex methodological decisions that are not well captured by traditional publication approaches. Various guidelines have emerged for achieving reproducibility, but implementation of these practices remains difficult due to the challenge of assembling software tools plus associated libraries, connecting tools together into pipelines, and specifying parameters. Here, we discuss a suite of cutting-edge technologies that make computational reproducibility not just possible, but practical in both time and effort. This suite combines three well-tested components-a system for building highly portable packages of bioinformatics software, containerization and virtualization technologies for isolating reusable execution environments for these packages, and workflow systems that automatically orchestrate the composition of these packages for entire pipelines-to achieve an unprecedented level of computational reproducibility. We also provide a practical implementation and five recommendations to help set a typical researcher on the path to performing data analyses reproducibly.

Abstract
Recent years have seen an explosion in the availability of paired molecular profiling and drug screen data, providing an unprecedented opportunity for the development of targeted therapies based on an individual’s genetic background. Despite a number of recent successes in diseases ranging from cystic fibrosis to cancer, significant hurdles remain in our ability to accurately predict treatments based on molecular profiling data. In particular, few such tools exist that allow the integration of heterogeneous data types (e.g. genomic, transcriptomic, and somatic mutations), along with high-throughput drug screen data to make predictions about treatment efficacy. Here, we describe a generalized open-source pipeline developed for the analysis of precision medicine data, Pharmacogenomics Prediction Pipeline, or “P3”. The modular design of P3 enables the inclusion of arbitrary input data types and the selection from multiple alternative machine learning algorithms, while automated statistical and visualization reporting steps incorporated throughout the pipeline assist in parameter tuning and early detection of problematic data components. Molecular profiling data is further enriched by the incorporation of external biological information in the form of pathway and gene set annotations such and Gene Ontology (GO) and The Molecular Signatures Database (MSigDB). To demonstrate the use of P3 for preclinical biomarker prediction, we applied P3 to an unpublished multiple myeloma dataset consisting of exome, RNA-Seq, CNV, and drug screen data for 1,912 compounds across 47 tumor cell lines. Specifically, P3 was used to predict molecular features associated with response to treatment for all drugs where a differential response to treatment was observed across patients. Furthermore, molecular profiling and drug screen data for 267 drugs and over a thousand cell lines spanning multiple cancer types from the Genomics of Drug Sensitivity in Cancer (GDSC) project were analyzed using P3, providing insights into shared mechanisms of drug sensitivity and resistance across different cancer and treatment types.

Abstract
Following fertilization, cortical granules exocytose ovastacin, a metalloendopeptidase that cleaves ZP2 in the zona pellucida surrounding mouse eggs to prevent additional sperm binding. Using high- and super-resolution imaging with ovastacinmCherry as a fluorescent marker, we characterize cortical granule dynamics at single granule resolution in transgenic mouse eggs. Newly-developed imaging protocols provide an unprecedented view of vesicular dynamics near the plasma membrane in mouse eggs. We discover that cortical granule anchoring in the cortex is dependent on maternal MATER and document that myosin IIA is required for biphasic trafficking to the plasma membrane. We observe local clearance of cortical actin during exocytosis and determine that pharmacologic or genetic disruption of trafficking to the plasma membrane impairs secretion of cortical granules and results in polyspermy. Thus, the regulation of cortical granule dynamics at the cortex-plasma membrane interface is critical for exocytosis and the post-fertilization block to sperm binding that ensures monospermic fertilization.

Abstract
A diagnosis of Alzheimer's disease (AD), a neurodegenerative disorder accompanied by severe functional and cognitive decline, is based on clinical findings, with final confirmation of the disease at autopsy by the presence of amyloid-β (Aβ) plaques and neurofibrillary tangles. Given that microstructural brain alterations occur years prior to clinical symptoms, efforts to detect brain changes early could significantly enhance our ability to diagnose AD sooner. Diffusion tensor imaging (DTI), a type of MRI that characterizes the magnitude, orientation, and anisotropy of the diffusion of water in tissues, has been used to infer neuropathological changes in vivo. Its utility in AD, however, is still under investigation. The current study used DTI to examine brain regions susceptible to AD-related pathology; the cerebral cortex, entorhinal cortex, and hippocampus, in 12-14-month-old 3xTg AD mice that possess both Aβ plaques and neurofibrillary tangles. Mean diffusivity did not differ between 3xTg and control mice in any region. Decreased fractional anisotropy (p < 0.01) and axial diffusivity (p < 0.05) were detected only in the hippocampus, in which both congophilic Aβ plaques and hyperphosphorylated tau accumulation, consistent with neurofibrillary tangle formation, were detected. Pathological tau accumulation was seen in the cortex. The entorhinal cortex was largely spared from AD-related neuropathology. This is the first study to demonstrate DTI abnormalities in gray matter in a mouse model of AD in which both pathological hallmarks are present, suggesting the feasibility of DTI as a non-invasive means of detecting brain pathology in vivo in early-stage AD.

Abstract
Abstract
Background: Shorter courses of APBI with novel fractionation schedules are being investigated; a large randomized trial from Europe has recently shown the safety and efficacy of a single-fraction adjuvant approach (with limited follow-up). We designed a prospective trial to identify and address the potential radiobiological and logistical limitations of single-fraction, intraoperative APBI.
Methods: We designed a single-arm, multi-institutional, prospective phase II trial that sequentially treats three cohorts of women (each n=30) with three progressively hypofractionated schedules. Eligible women were age ≥ 50 years with unifocal invasive or in situ tumors ≤ 3.0 cm, excised with negative margins, and with negative lymph nodes and positive hormone-receptors. Using a reference schedule of 60 Gy delivered in 2 Gy fractions, and assuming tumor parameters: a/b = 4 Gy; a = 0.27 Gy-1, and repopulation parameters of: Teff = 26 days; delay time = 0 days, the reference tumor BED is ∼ 86 Gy4. We began with a schedule of 4 fractions of 7 Gy delivered twice-daily using a Contura MLB multi-lumen device. We defined very conservative dosimetric criteria for acceptability: maximum skin and rib dose to not exceed 100% of prescription dose, and V150 and V200 to not exceed 40 cc and 10 cc, respectively. Subsequent schedules are 3 fractions of 8.25 Gy and 2 fractions of 10.25 Gy, both delivered over 2 days. The primary endpoint is to exclude a local failure rate exceeding 10% with the upper limit of a 95% confidence interval.
Results: A total of 30 patients have been enrolled at the 7 Gy × 4 fractions dose-level and followed for a minimum of 6 months. The median skin dose as a percent of prescription dose (PD) was 84% (40–100) and the median rib dose was 71% (16–119). 96% of the PTV_eval received a median of 95% of PD (range 85–103). The V150 (range 14–48cc) and V200 (range 0–29cc) criteria were met in all cases. One breast infection occurred and was treated; 2 cases of symptomatic fat necrosis and 2 cases of symptomatic seromas occurred. No acute toxicities greater than CTCAE grade 2 have been observed.
Conclusion: Short-course APBI is dosimetrically feasible using the Contura MLB and appears to be tolerable in terms of acute toxicities. Our approach is based on well-defined radiobiological parameters and allows for an abbreviated course of treatment that is guided by full pathological review and the ability to objectively achieve and validate acceptable dosimetric criteria in each case. We have opened enrollment to the next schedule of 8.25 Gy for three fractions.

Abstract
CTCF sites are abundant in the genomes of diverse species but their function is enigmatic. We used chromosome conformation capture to determine long-range interactions among CTCF/cohesin sites over 2 Mb on human chromosome 11 encompassing the beta-globin locus and flanking olfactory receptor genes. Although CTCF occupies these sites in both erythroid K562 cells and fibroblast 293T cells, the long-range interaction frequencies among the sites are highly cell type specific, revealing a more densely clustered organization in the absence of globin gene activity. Both CTCF and cohesins are required for the cell-type-specific chromatin conformation. Furthermore, loss of the organizational loops in K562 cells through reduction of CTCF with shRNA results in acquisition of repressive histone marks in the globin locus and reduces globin gene expression whereas silent flanking olfactory receptor genes are unaffected. These results support a genome-wide role for CTCF/cohesin sites through loop formation that both influences transcription and contributes to cell-type-specific chromatin organization and function.

Abstract
Foxo-1, a member of the Foxo forkhead type transcription factors, is markedly upregulated in skeletal muscle in energy-deprived states such as fasting, cancer and severe diabetes. In this study, we target the Foxo-1 mRNA in a mouse skeletal myoblast cell line C2C12 and in vivo models of normal and cancer cachexia mice by a Foxo-1 specific RNA oligonucleotide. Our results demonstrate that the RNA oligonucleotide can reduce the expression of Foxo-1 in cells and in normal and cachectic mice, leading to an increase in skeletal muscle mass of the mice. In search for the possible downstream target genes of Foxo-1, we show that when Foxo-1 expression is blocked both in cells and in mice, the level of MyoD, a myogenic factor, is increased while a muscle negative regulator GDF-8 or myostatin is suppressed. Taken together, these results show that Foxo-1 pays a critical role in development of muscle atrophy, and suggest that Foxo-1 is a potential molecular target for treatment of muscle wasting conditions.

Abstract
Orbital myositis is an inflammatory disorder of the orbital muscles causing orbital pain and restriction of eye movements. Although rare in children, it is most frequently seen after orbital trauma or as a post-infectious process. We describe a child with chronic relapsing psoriasis, juvenile psoriatic arthritis and relapsing bilateral orbital myositis.

Abstract
Dentists modify and construct occlusions. This occurs on a daily basis in the disciplines of restorative, fixed and removable prosthetics and orthodontics. These procedures influence the TMJ, the muscles of mastication, the supporting structure of the teeth and the teeth as well. Dentists have an opportunity to not only objectively analyze how they all interrelate, but to create a physiological harmonious relationship. This will reduce a traumatic occlusion to one that is within the histological adaptive range for the tissue to accommodate. This knowledge can be applied to not only help patientsí pain and dysfunction, but to ensure confidence that dentists are not going to be responsible for iatrogenic results. The future of dentistry is not only being able to effectively deal with TMD but to prevent the problems. Management of mandibular whiplash and migraine headaches are also becoming our responsibility. Dentists are the specialists of occlusion. With the technology available to render this quality of care, they must fulfill their obligation to the public, take responsibility and continue to increase their capability. This approach to dentistry provides a new "window of opportunity" as its many applications have yet to be explored.

Abstract
Temporomandibular disorder (TMD) is a reality. Surveys place the incidence at about 20-50%. For decades debate has raged as to whether this is a medical or dental problem. Scientific study of anatomy, biochemistry, physiology, and objective analysis with kinesiology, electromyography and sonography, along with case history all point to the same thing; occlusion affects the joint and the muscles. This is our profession's "crown jewel". We diagnose, construct and modify our patient's occlusion. It is about time we all agree, understand, take responsibility and start cooperating in preventing and treating this common malady that seriously affects the quality of life of many.

Abstract
In order to determine the safety of reducing maintenance neuroleptic dose in long-term ambulatory schizophrenia, a step-wise depot reduction study was carried out on patients over a six month period. Doses were reduced by 1/8 of original approximately every two months for a total of three reductions. At the end of dose reduction and at six month follow-up, relapse rate was calculated. Relapse in this study was defined as the clinical decision to either increase neuroleptic dose or to hospitalize. Approximately 50% of the patients relapsed. There was no association with life events as measured by the Paykel scale. Where relapse occurred, it was usually seen subsequent to the second dose reduction. Patients who survived dose reduction had been maintained for a significantly longer period on depot neuroleptics and tended to suffer from a form of schizophrenia which required the co-administration of antidepressants. The findings show that, for a population on long-term depot medication, the risk of symptom exacerbation after gradual step-wise neuroleptic reduction is 50%. The results help to delineate which patients will fall into that 50%.

Abstract
The therapeutic efficacy of intact and F(ab')2 fragments of a 131I anti-CEA antibody were compared in an established LS174T colonic xenograft model in nude mice. A single IV dose of either 0.5 mCi (18.5 MBq) intact or 1.0 mCi (37 MBq) F(ab')2 fragments significantly delayed tumour growth, and increased survival time to the same extent. Biodistribution studies showed that the more rapid clearance of the fragments from the circulation improved the tumour: normal tissue ratios found for the intact antibody, but reduced the duration and therefore absolute amount of radioantibody localisation (% injected dose/gram) at the tumour site. The tumours received a similar accumulated beta radiation dose, with 4,065 cGy from 0.5 mCi intact antibody and 4,500 cGy from 1.0 mCi F(ab')2 fragments. The dose rate to the tumour was initially higher for the fragments, but fell off more rapidly as clearance occurred. However, the rapid circulatory clearance resulted in a radiation dose of only 995 cGy to the blood, compared with 2,300 cGy for the intact antibody. This suggests that twice the radiation dose could be delivered to the tumour in the form of fragments for the same blood dose from the intact antibody. Fractionating the 1.0 mCi dose of F(ab')2 into three doses of 0.33 mCi (12.2 MBq), given on days 1, 3 and 5, significantly reduced the therapeutic effect of the treatment. The clinical relevance of these findings is discussed.

Abstract
The object of this study was to determine if a strong association between soft drink (soda) consumption and recurrence of urinary stone disease, found in an earlier case-control study of adult males, had a causal component. The study sample consisted of 1009 male subjects, who completed an episode of urinary stone disease, who were aged 18-75 at that time, and who reported consuming at least 160 ml per day of soft drinks. Half of the subjects were randomized to refrain from consuming soft drinks, while the remaining subjects served as controls. The intervention group had an observed 6.4% advantage in actuarial 3 yr freedom from recurrence (p = 0.023 one-sided) over the control group. One important secondary finding was that for those who reported at the time of the index stone that their most consumed drink was acidified by phosphoric acid but not citric acid, the experimental group had a 15% higher 3 yr recurrence-free rate than the controls, p = 0.002, while for those who reported at the time of the index stone that their most consumed drink was acidified by citric acid with or without phosphoric acid, the experimental group had a similar 3 yr recurrence-free rate to the controls, p = 0.55. This interaction was significant, p = 0.019.

Abstract
Radioimmunotherapy in humans is limited by toxicity to normal tissues, caused by circulating radio-antibody. Second antibody directed against the first (anti-tumor) antibody accelerates clearance of first antibody from normal tissues, and may thus improve the therapeutic ratio. The effect of second antibody both on anti-tumor antibody distribution and on tumor and normal tissue radiation doses, has been investigated in nude mice bearing colonic tumor xenografts. Second antibody, given either 6 or 24 hr after the first, rapidly cleared circulating activity and reduced the calculated radiation dose to all tissues except the spleen, where it rose by 11 and 43% respectively. The dose received by the blood fell by 87% and 71%, while that to the tumor was reduced by 81% and 58%, after 6 or 24 hr second antibody. Administration of second antibody therefore improved the tumor to blood ratios. Tumor identification by gamma camera was greatly facilitated by the use of second antibody, and required no background subtraction. Results obtained from this system demonstrate the utility of second antibody in protecting normal tissues from prolonged circulating radioactivity during radioimmunotherapy.

Abstract
The number of genetic disorders detectable antenatally by the use of DNA probes has risen rapidly. The demand for diagnosis and termination of affected pregnancies in high-risk families is likely to increase as tests become more accurate and widely known. Each Regional Health Authority (RHA) must therefore urgently compare any financial savings to be made from a DNA diagnostic service with the cost of setting up and running a laboratory. There are great difficulties in conducting a formal cost-benefit analysis, but the pressing need for a cost appraisal made a more limited cost-savings approach necessary. This paper uses a broad-brush approach for all disorders and known costs for inpatient hospital care only. Despite the limitations of the method, in the two regions studied (North West and South East Thames) there would be clear savings at hospital level if a DNA screening laboratory were set up in each region. Funds released from treatment of genetic disorders could be used for other purposes. There are benefits to the families concerned, social service and educational savings, and other health service savings not considered here. On hospital costs alone there are benefits from the programme and wider consideration will make it more cost-effective. Once a programme is set up, new developments will make it even more cost-effective. It is concluded that RHAs should attach high priority to the setting up of such laboratories.

Abstract
The use of nasoenteral alimentation in many neurologically depressed patients is a common practice. These patients are also at increased risk of sustaining feeding tube malplacement. The morbidity and mortality involving feeding tube malposition in these debilitated patients is high. In this paper, we present four case reports of morbidity, with one resultant mortality, associated with small-bore nasoenteral tube malposition. We are also suggesting a nasoenteral intubation protocol which we feel will decrease the incidence of feeding tube malplacement.

Abstract
Preschool children with suspected impairment of hearing present the challenge of early recognition and prompt referral for diagnosis. Unfortunately, referral is seldom prompt. Most of this delay stems from most primary care physicians' unwillingness to listen to parents' opinions, their lack of knowledge about deafness in children, failure to perform routine screening tests for hearing, and reluctance to refer to a proper diagnostic facility.This paper outlines manifestations of deafness in early childhood, simple office hearing tests, and selection of patients for referral.
