    Abstract Background: Pregnancy denial can be broken into two major types, non-psychotic and psychotic deniers, and further classified into pervasive, affective and persistent sub-types. It can lead to increased morbidity and mortality of the mother and neonate. Psychotic pregnancy denial is rare and the medical literature existing on the subject is limited to a small number of case reports and case series. No formal recommendation exists on the clinical management of psychotic pregnancy denial in the antenatal or postpartum period. The authors provide a comprehensive review of the literature regarding psychotic pregnancy denial, present an example of an unpublished case and provide suggestions for clinical management.
    Case: A 33-year-old primigravida at 37 6/7 weeks gestation presented with new-onset psychotic pregnancy denial with no prior history of psychosis. She had a negative medical work-up for organic causes of psychosis. Using a multidisciplinary approach, the decision was made to deliver the fetus at 38 1/7 weeks
    Conclusion: Psychotic pregnancy denial is rare and potentially dangerous. Delivery prior to 39 weeks gestation is reasonable for worsening psychiatric disease but careful consideration of the risk-benefit analysis and ethical framework must be deliberated.

    Abstract The recent 2016 deeming of cigars by the US Food and Drug Administration (FDA) has led to increased interest in cigar science, including ways to accurately measure the harmful and potentially harmful constituents (HPHCs) found within mainstream cigar smoke. At present, there are standardized methods for evaluating HPHCs in mainstream cigarette smoke but none specific to cigar analysis except for nicotine and carbon monoxide. This study sought to analyze carbonyl delivery in marketed cigars and cigarillos and compare them against levels found in cigarettes. To accomplish this the standard cigarette method, CORESTA recommended method 74 (CRM-74), was optimized for cigar smoking including an evaluation of the trapping efficiency and the stability of the carbonyl-hydrazone adducts due to the increased smoke time required for cigar collection. On a per product basis, carbonyl delivery from cigars smoked under CRM-64 conditions was found to yield similar levels of formaldehyde and greater levels of acetaldehyde, acrolein and crotonaldehyde than measured in mainstream cigarette smoke collected under conditions prescribed under ISO standard 3308. Furthermore, on a per product basis, cigarettes smoked under the ISO 20778 intense smoking regime delivered higher levels of formaldehyde, acrolein and crotonaldehyde as compared to cigars smoked under the CORESTA regime, while acetaldehyde was found to be higher in mainstream cigar smoke. Given the recent deeming, this work expands upon previously reported work, limited in scope by either number of products or analytes reported, through the analysis of carbonyl delivery found in the mainstream smoke for 12 brands of cigars and cigarillos.

    Abstract Heterotopic pregnancies are rare and are usually diagnosed by transvaginal ultrasound. Despite the routine use of sonography in early pregnancy, artifact created by mirror imaging can drastically and erroneously alter medical decision making by interfering with image interpretation. A heterotopic pregnancy with a single intrauterine gestation and twin left adnexal ectopic gestational sacs was observed on ultrasound in a woman presenting with abdominal pain. During laparoscopy, an ectopic pregnancy was not identified, and subsequent intraoperative ultrasound reproduced the heterotopic pregnancy through manipulation of bowel, confirming mirror image artifact. This phenomenon is rarely seen in obstetric imaging; therefore, lack of awareness can lead to false diagnosis of heterotopic pregnancy. Techniques to verify correct diagnosis should be used to resolve potential mirror artifact before proceeding with surgical management.

    Abstract In this chapter we review the regulation and execution of the meiotic cell divisions in the context of the developmental program that comprises Drosophila spermatogenesis. Male germ line cells undergoing meiosis are readily identifiable and are of a size and abundance that makes this system well suited for morphological characterizations of cell division. Furthermore, a wide range of molecular genetic techniques are available, facilitating mechanistic investigations. We present an overview of key stages in spermatogenesis and, in particular, meiosis. We consider the pathways controlling entry into the meiotic divisions in the context of established cell cycle regulators as well as newly identified loci required for meiotic entry. We then review the assembly and function of both the meiotic spindle and the contractile ring. We conclude with a consideration of questions and problems that await further investigation.

    Abstract Boule, a Drosophila orthologue of the vertebrate Dazl fertility factors, is a testis-specific regulator of meiotic entry and germline differentiation. Mutations inactivating either Boule, which is an RNA-binding protein, or Twine, which is a Cdc25-type phosphatase, block meiotic entry in males. Here we show that twine and boule interact genetically. We also find that protein expression from twine messenger RNA correlates with cytoplasmic accumulation of Boule and is markedly reduced by boule mutations. Remarkably, heterologous expression of Twine rescues the boule meiotic-entry defect, indicating that the essential function of Boule at the transition from G2 to M phase during meiosis is in the control of Twine translation.

    Abstract Many adverse drug reactions leading to hepatotoxicity are caused by the cytochrome P450-dependent activation of non-toxic drugs or chemicals into reactive metabolites. To this end, adenoviruses were used as a tool to efficiently deliver specific CYP genes into cultured cells (i.e., human hepatoma cell line HepG2). Recombinant-defective adenoviral vectors encoding for genes CYP3A4 (Adv-CYP3A4), CYP2E1 (Adv-CYP2E1), CYP2A6 (Adv-CYP2A6) and CYP1A2 (Adv-CYP1A2) were used to confer specific CYP drug metabolic capabilities to HepG2 cells. Upgraded cells transiently expressed single specific cytochrome P450 enzymatic activities in terms of the number of the infecting virus particles used in their transduction. HepG2 cells transduced with adenoviruses and wild HepG2 cells cultured in 96 well-plates were incubated in the presence of model compounds, some of which can be metabolized to reactive metabolites. After compound exposure, cell viability was assessed by the commonly used MTT assay. The results confirm that the cell-based assay is a valuable tool in toxicology assessments and high-throughput screenings to detect cytotoxicity mediated by cytochrome P450 biotransformation in preclinical drug development. The assay also has a potential applicability in other industrial sectors such as the chemical industry.

    Abstract Objective: To determine if the intrapartum use of a 5% glucose-containing intravenous solution decreases the chance of a cesarean delivery for women presenting in active labor.
    Methods: This was a multi-center, prospective, single (patient) blind, randomized study design implemented at four obstetric residency programs in Pennsylvania. Singleton, term, consenting women presenting in active spontaneous labor with a cervical dilation of <6 cm were randomized to lactated Ringer's with or without 5% glucose (LR versus D5LR) as their maintenance intravenous fluid. The primary outcome was the cesarean birth rate. Secondary outcomes included labor characteristics, as well as maternal or neonatal complications.
    Results: There were 309 women analyzed. Demographic variables and admitting cervical dilation were similar among study groups. There was no significant difference in the cesarean delivery rate for the D5LR group (23/153 or 15.0%) versus the LR arm (18/156 or 11.5%), [RR (95% CI) of 1.32 (0.75, 2.35), p = 0.34]. There were no differences in augmentation rates or intrapartum complications.
    Conclusions: The use of intravenous fluid containing 5% dextrose does not lower the chance of cesarean delivery for women admitted in active labor.

    Abstract Although sodium hypochlorite is routinely used as an irrigant, the scope and limitation of another hypohalide sodium hypobromite has not been adequately studied. The objective of this study was to compare the cytotoxic effects of sodium hypobromite and sodium hypochlorite on human osteoblasts by evaluating cell proliferation. One day after plating and every other day after that, cells were treated with a combination of sodium hypochlorite and sodium bromide, resulting into three molar ratios of activated sodium hypobromite. Positive control cells were not treated with hypohalides, while negative controls were separately treated with hypochlorite or bromide alone. Photomicrographic analysis of the cultures was done on days 1 and 6 of treatment. Trypsinized cells were counted to determine cell proliferation. Our results show that sodium bromide is more cytotoxic compared to sodium hypochlorite or activated sodium hypobromite. In activated sodium hypobromite, 4:1 molar ratio was less cytotoxic compared to other molar ratios.

    Abstract The Drosophila boule gene is expressed exclusively in the male germline and encodes an RNA binding protein closely related to the mammalian fertility factors encoded by the DAZ (Deleted in Azoospermia) and DAZL (DAZ-like) genes. Mutation of boule blocks both meiotic divisions. Differentiation nonetheless continues, resulting in tetraploid spermatids that fail to mature into sperm. We have found that Boule localizes premeiotically to a perinucleolar region and then translocates to the cytoplasm at the onset of meiosis. We show that deletion of the Y chromosome ks-1 fertility locus eliminates Boule nuclear localization, although it does not perturb entry into meiosis. Based on these observations we propose that Boule acts in the cytoplasm to regulate the stability or translation of messenger RNA encoding an essential meiotic factor.
