BACKGROUND: The aim of study was to evaluate the application of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride regarding their effect on the shear bond strength (SBS), bond failure pattern of brackets using the adhesive remnant index (ARI) and assessing the quality of enamel surface using the enamel damage index (EDI). MATERIAL AND METHODS: Sixty extracted premolar teeth were randomly divided into four groups regarding pretreatment application of CPP-ACP and fluoride...

Enoyl-ACP reductase (ENR, also known as FabI) has received considerable interest as an anti-bacterial target due to its essentiality in fatty acid synthesis. All the FabI structures reported to date, regardless of the organism, are composed of homo-tetramers, except for two structures: Bacillus cereus and Staphylococcus aureus FabI (bcFabI and saFabI, respectively), which have been reported as dimers. However, the reason for the existence of the dimeric form in these organisms and the biological meaning of dimeric and tetrameric forms of FabI are ambiguous...

Gonadotropin-releasing hormones (GnRHs) play pivotal roles in reproductive functions via the hypothalamus, pituitary, and gonad axis, namely, HPG axis in vertebrates. GnRHs and their receptors (GnRHRs) are likely to be conserved in invertebrate deuterostomes and lophotrochozoans. All vertebrate and urochordate GnRHs are composed of 10 amino acids, whereas protostome, echinoderm, and amphioxus GnRH-like peptides are 11- or 12-residue peptide containing two amino acids after an N-terminal pyro-Glu. In urochordates, Halocynthia roretzi GnRH gene encodes two GnRH peptide sequences, whereas two GnRH genes encode three different GnRH peptides in Ciona intestinalis...

PURPOSE: The purpose of this study was to explore the acceptability, applicability, and understandability of a promising advance care planning (ACP) web-based resource for use with oncology patients, and determine whether revisions to the website would be necessary before implementation into oncology care. The resource is called PREPARE ( www.prepareforyourcare.org ) and it had not been tested for use within oncology, but had previously been shown to influence the readiness of older, community-dwelling adults to engage in ACP behaviors...

INTRODUCTION: Although 80% of patients endorse an advance directive (AD), less than 35% of American adults have a documented AD. Much research has been done on barriers to creating ADs; however, there is a paucity of research addressing motivations for creating ADs. Previous research has identified 4 categories of influence for engaging in advance care planning (ACP). This study aimed to quantify the influence of these 4 motivating categories in creating an AD. METHODS: Participants included 238 adults with documented ADs...

OBJECTIVE: To identify diagnostic groups and the form of the trajectory of functional decline that has the potential to enhance advance care planning (ACP) in a nursing home (NH) population. METHODS: Retrospective, longitudinal study with dependent variable (function) derived from the Resident Classification Scale (RCS), 1997-2008. Trajectory modelling used linear and curvilinear terms. RESULTS: The organ failure or other residents have a linear average functional decline...

Records of 56 Persian fallow deer (Dama dama mesopotamica) immobilized for translocation were reviewed. Twenty-three were administered 0.05 ± 0.01 (mean ± SD) mg/kg thiafentanil (THIA), 20 were administered 0.045 ± 0.008 mg/kg thiafentanil combined with 0.19 ± 0.03 mg/kg azaperone (THIA-AZP), and 13 were administered 0.032 ± 0.04 mg/kg etorphine-acepromazine (ETOR-ACP) by intramuscular remote injection. Parameters recorded and compared between groups included induction and recovery times, heart rate, respiratory rate, rectal temperature, oxygen saturation, blood pressure, reflexes, quality of immobilization, and blood concentrations of lactate and glucose...

INTRODUCTION: Code status discussions form an important part of advance care planning (ACP) as it enables physicians to respect the patient's wishes for end-of-life care. However, in some cases, code status discussions can be challenging causing the physician to go against the patient's wishes and the code of medical ethics. This is especially true in an emergency setting. In this paper, we will discuss three cases of advanced cancer patients, where code status discussions posed challenges to healthcare providers...

BACKGROUND: Anterior clinoidal meningiomas (ACM) are traditionally approached through transcranial routes. Due to their tendency to extend laterally and their proximity to vital neurovascular structures, the endoscopic transnasal suprasellar approach is still questionable. We present and describe an ACM case that underwent an endoscopic transnasal suprasellar approach, and provide a review of the literature and operative technique. CASE DESCRIPTION: A 56 year-old lady who presented with chronic left-sided decreased vision...

Introduction: Many patients seeking orthodontic treatment already have incipient enamel lesions and should be placed under preventive treatments. The aim of this in vitro study was to evaluate the effect of CPP-ACP paste and CO2 laser irradiation on demineralized enamel microhardness and shear bond strength of orthodontic brackets. Methods: Eighty caries-free human premolars were subjected to a demineralization challenge using Streptococcus mutans. After demineralization, the samples were randomly divided into five equal experimental groups: Group 1 (control), the brackets were bonded without any surface treatment; Group 2, the enamel surfaces were treated with CPP-ACP paste for 4 minutes before bonding; Group 3, the teeth were irradiated with CO2 laser beams at a wavelength of 10...

Yu Yan, Dongmei Xu
Intrauterine adhesions (IUA) can lead to partial or complete closure of the uterine cavity, which may result in symptoms including abnormal menstruation, infertility, and pelvic pain. A network meta-analysis was performed to assess the effect of adjuvant therapy on the prevention and treatment of intrauterine adhesions. We searched electronic databases, including PubMed, EmBase, and the Cochrane Library, up to May 5, 2017 without language restrictions. The primary outcomes in the present analysis were the rate of IUAs for prevention and the rate of IUA recurrence for treatment...

BACKGROUND: Advance care planning (ACP) can positively affect end-of-life care experiences. However, uptake of ACP completion is low. The aim of this study was to investigate whether co-locating ACP facilitators in general practice increased participation METHODS: Barwon Health commenced promoting its ACP program in 2008. Trained ACP facilitators assisted consumers, which usually occurred in the program's community-based consulting rooms. From 2012 onwards, ACP facilitators were co-located with 18 general practices, where they assisted consumers at the point of care...

BACKGROUND: The benefit of palliative care referral for severe stroke patients on end-of-life care pathways (EOLCP) is increasingly recognised. Palliative care provides assistance with symptom management and transition to end-of-life care. Advance care planning (ACP) may help accommodate patient/family expectations and guide management. METHOD: Retrospective study of all stroke deaths (2014-2015) at Liverpool Hospital, Sydney, Australia. Data examined included age, co-morbidities, living arrangements, pre-existing ACP, palliative care referral rates and 'survival time'...

Mammalian mitochondrial ribosomes (mitoribosomes) have less rRNA content and 36 additional proteins compared with the evolutionarily related bacterial ribosome. These differences make the assembly of mitoribosomes more complex than the assembly of bacterial ribosomes, but the molecular details of mitoribosomal biogenesis remain elusive. Here, we report the structures of two late-stage assembly intermediates of the human mitoribosomal large subunit (mt-LSU) isolated from a native pool within a human cell line and solved by cryo-EM to ∼3-Å resolution...

CONTEXT: Evidence is mixed regarding the impact of advance directives (AD) on the utilisation of end-of-life treatments. OBJECTIVES: This study evaluated the effect of AD on the utilization of end-of-life treatments during the last month of life in older patients. METHODS: Taipei City Hospital initiated an advance care planning (ACP) program to promote AD for admitted patients in 2015. This prospective study recruited deceased older patients who completed ACP communication between 2015 and 2016...
