RNA expression in plant mitochondria implies a large number of post-transcriptional events in which transcript processing and stabilization are essential. In this study, we analyzed the function of the Arabidopsis mitochondrial stability factor 2 gene (MTSF2) and show that the encoded pentatricopeptide repeat protein is essential for the accumulation of stable nad1 mRNA. The production of mature nad1 requires the assembly of three independent RNA precursors via two trans-splicing reactions. Genetic analyses revealed that the lack of nad1 in mtsf2 mutants results from the specific destabilization of the nad1 exons 2-3 precursor transcript...

INTRODUCTION: Women with abnormal uterine bleeding (AUB) report significant reductions in quality of life (QOL), which can be attributed in many cases to the fear of embarrassing episodes of bleeding. We performed this study to determine whether or not during clinical encounters physicians addressed the impact of AUB on patient-reported QOL. MATERIALS AND METHODS: Between October 2008 and May 2009, we conducted a cross-sectional study of members of the American College of Obstetricians and Gynecologists...

During eukaryotic translation initiation, eIF3 binds the solvent-accessible side of the 40S ribosome and recruits the gate-keeper protein eIF1 and eIF5 to the decoding center. This is largely mediated by the N-terminal domain (NTD) of eIF3c, which can be divided into three parts: 3c0, 3c1, and 3c2. The N-terminal part, 3c0, binds eIF5 strongly but only weakly to the ribosome-binding surface of eIF1, whereas 3c1 and 3c2 form a stoichiometric complex with eIF1. 3c1 contacts eIF1 through Arg-53 and Leu-96, while 3c2 faces 40S protein uS15/S13, to anchor eIF1 to the scanning pre-initiation complex (PIC)...

BACKGROUND: Medical management for perforated diverticulitis without abscess or peritonitis (PDwAP) has a success rate of 40-70%. Identifying patients with a risk of medical treatment failure would improve outcomes. The aim of this study was to identify the risk factors for failure of medical treatment in patients admitted with PDwAP. METHODS: This multicenter retrospective observational study included all consecutive patients admitted for PDwAP and not surgically treated over a 7-year period...

GaAs was central to the development of quantum devices but is rarely used for nanowire-based quantum devices with InAs, InSb and SiGe instead taking the leading role. p-type GaAs nanowires offer a path to studying strongly confined 0D and 1D hole systems with strong spin-orbit effects, motivating our development of nanowire transistors featuring Be-doped p-type GaAs nanowires, AuBe alloy contacts and patterned local gate electrodes towards making nanowire-based quantum hole devices. We report on nanowire transistors with traditional substrate back-gates and EBL-defined metal/oxide top-gates produced using GaAs nanowires with three different Be-doping densities and various AuBe contact processing recipes...

Postoperative complications following prosthetic mesh repair are relatively rare and depend on the type and location of prosthetic mesh. They include abscess, hematoma, seroma, fistula, bowel obstruction, mesh retraction, granuloma and recurrent hernia. Computed tomography (CT) is the imaging examination of choice for the diagnosis of such complications. This pictorial review illustrates the CT presentation of the most and less common postoperative complications following prosthetic mesh repair of the abdominal wall...

BACKGROUND AND AIMS: Perimenopause is marked by clinical manifestations which disturb everyday life and which may also hide a pathomorphological, more precisely endometrial, substrate. An accurate early diagnosis established by accessible, non-invasive methods is very important for the therapeutic management. METHOD: The study included 103 patients aged between 41.5-55.11 years, divided into 3 age groups: 40-44 years (n=10), 45-49 years (n=54) and ≥50 years (n=39)...

REVIEW
Oskari Heikinheimo, Ian Fraser
Hormonal treatment of abnormal uterine bleeding (AUB), especially bleeding related to endometrial causes (AUB-E), ovulatory dysfunction (AUB-O) and coagulopathy (AUB-C), and to some extent, uterine leiomyomas and adenomyosis, has become the first-line evidence-based management strategy during recent years. Hormonal treatment of heavy menstrual bleeding (HMB) is also endorsed as the first line of treatment in several international guidelines. In the present article, we review the efficacy of the commonly used and widely available hormonal treatments of AUB-O, AUB-E and AUB-C...

PURPOSE: The aim of this study was to assess the performances of unenhanced post-mortem computed tomography (CT) to detect thoracic injuries in violent death. MATERIALS AND METHODS: Retrospectively, we conducted a review of unenhanced CT scans of 67 victims of violent deaths with thoracic injuries and compared CT findings with the results of clinical autopsy. Our gold standard was a comparison of CT scans with autopsy discussed in a monthly forensic radiology multidisciplinary team meeting (MDTM)...

BACKGROUND: Few studies on the relations between sleep quantity and/or quality and cognition have been conducted among preschoolers from healthy general population. We aimed at identifying, among 36 months old children, early factors associated with intelligence quotient (IQ) estimated through the Weschler Preschool and Primary Scale Intelligence-III test and its indicators: Full-Scale-, Verbal- and Performance-IQs and their subscale scores. METHODS: We included 194 children from the French birth cohort AuBE with both available Weschler Preschool and Primary Scale Intelligence-III scores at three years and sleep data...

BACKGROUND: In chronic hepatitis C, the European Association for the Study of the Liver - Asociacion Latinoamericana para el Estudio del Higado recommends performing transient elastography and a blood test to diagnose significant fibrosis; test concordance confirms diagnosis. AIM: To validate this rule and improve it by combining a blood test, FibroMeter (virus second generation, Echosens, Paris, France) and transient elastography (constitutive tests) into a single combined test, as suggested by the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America...

Traumatic urethral catheterization may result in a number of serious complications. A rare occurrence is the development of a urethral pseudoaneurysm. We report the case of a 13-year-old male who required placement of a Foley catheter for an orthopedic surgical procedure. The Foley was misplaced in the bulbourethra, resulting in the development of a bulbar artery pseudoaneurysm. Profuse bleeding via the urethra was noted after removal of the catheter, and the patient experienced severe intermittent hematuria during the postoperative period...

The present study tests a multilevel mediation model concerning the effect of shared leadership on team members' flow experience. Specifically, we investigate the mediating role of teamwork behaviors in the relationships between 2 complementary indicators of shared leadership (i.e., density and centralization) and flow. Based on a multisource approach, we collected data through observation and survey of 111 project teams (521 individuals) made up of university students participating in a project management simulation...

The aim is to compare hysteroscopy, two-dimensional transvaginal ultrasound (2D TVUS), and three-dimensional (3D) Virtual Organ Computer-aided AnaLysis™ (VOCAL) to detect endometrial polyps (EPs) in premenopausal women with abnormal uterine bleeding (AUB). This prospective study was done at Ain Shams Maternity Hospital, Egypt, from March 5, 2015, to December 30, 2015, enrolling 118 premenopausal women with AUB. 2D TVUS, 3D VOCAL, and hysteroscopy were done. 109 patients reached final analysis. 36 women (33%) were diagnosed with EP by 2D TVUS...

REVIEW
T Justin Clark, Helen Stevenson
The diagnosis and treatment of endometrial polyps will be familiar to most gynaecologists. However, the aetiology and natural history of these focal intrauterine lesions are yet to be elucidated. This lack of clarity is also true with regard to their clinical significance; whilst endometrial polyps are highly prevalent in all types of abnormal uterine bleeding (AUB), they are also commonly found in women without AUB. These controversies will be discussed along with current thoughts on the diagnosis and treatment of endometrial polyps...
