This prospective clinical study evaluated the morphological and positional mandibular asymmetry of young patients with functional unilateral posterior crossbite. The sample included 9 girls and 6 boys (8.8 +/- 1.0 years of age), evaluated at the initiation of treatment and approximately 6 months after the retention phase (1.1 +/- 0.2 years after initiation of treatment). Each patient had a complete unilateral posterior crossbite involving 3 or more posterior teeth, a functional shift ...

The baculovirus antiapoptotic protein p35 inhibited the proteolytic activity of human interleukin-1 beta converting enzyme (ICE) and three of its homologs in enzymatic assays. Coexpression of p35 prevented the autoproteolytic activation of ICE from its precursor form and blocked ICE-induced apoptosis. Inhibition of enzymatic activity correlated with the cleavage of p35 and the formation of a stable ICE-p35 complex. The ability of p35 to block apoptosis in different pathways and in ...

INTRODUCTION: During interfacility transport, the length of time taken by the transport team to prepare the patient for transport is often perceived as a problem by referring hospital staff. The purpose of this study was to examine the effects on time at the referring hospital of the number and complexity of interventions performed by the transport team to stabilize the patient prior to transfer.

SETTING: Interfacility transfers by the provincial infant transport team (ITT) to British ...

We live in a world that is largely socially constructed, and we are constantly involved in and fundamentally influenced by a broad array of complex social interactions. Social behaviors among conspecifics, either conflictive or cooperative, are exhibited by all sexually reproducing animal species and are essential for the health, survival, and reproduction of animals. Conversely, impairment in social function is a prominent feature of several neuropsychiatric disorders, such as autism ...

Heterogeneous transcriptional start site usage by HIV-1 produces 5'-capped RNAs beginning with one, two, or three 5'-guanosines (Cap1G, Cap2G, or Cap3G, respectively) that are either selected for packaging as genomes (Cap1G) or retained in cells as translatable messenger RNAs (mRNAs) (Cap2G and Cap3G). To understand how 5'-guanosine number influences fate, we probed the structures of capped HIV-1 leader RNAs by deuterium-edited nuclear magnetic resonance. The Cap1G transcript adopts a ...

Summary.  The paper considers the use of level-of-effort (LOE) paradata to model the non-response mechanism in surveys and to adjust for non-response bias, particularly bias that is missing not at random or non-ignorable. Our approach is based on an unconditional maximum likelihood estimation (call-back) model that adapts and extends the prior work to handle the complexities that are encountered for large-scale field surveys. A test of the ‘missingness at random’ assumption is also ...

A review of the Western mental health scales that have been utilized in Nepal was conducted. Academic search engines (PubMed, MEDLINE, PsychLIT, Social Sciences Citation Index, and Anthropology Plus) were searched using relevant terms for the years 1990-2011. Search results indicated a limited number of mental health scales had been used and/or developed in Nepal with mixed emphasis on reliability and validity, as well as cultural considerations. These scales, methods and limitations are ...

Importance. As Rivaroxaban has increased in popularity, it has been accompanied with a growing body of evidence displaying its ability to cause drug induced liver injury (DILI). Observation. A 74-year-old Caucasian female developed Rivaroxaban DILI two weeks after finishing a 14-day course. The patient was symptomatic and jaundiced with elevated transaminases and hyperbilirubinemia with normal lab values two months priorly. Liver biopsies showed mixed inflammatory infiltrate of ...

We propose improving system availability by performing in-field repair at the chip level. This enables margining and detection of degrading memory cells before the user observes any errors. A 576 Mb embedded DRAM at 1.5 GHz in a 40nm CMOS technology achieves improved resilience to both aging memory cells and cells with variable retention time (VRT). Un-interrupted user access of 6 billion 72-bit read and write operations per second is maintained during background repair.

How genetic variation arises and persists over evolutionary time despite the depleting effects of natural selection remains a long-standing question. Here, we investigate the impacts of two extreme forms of population regulation-at the level of the total, mixed population (hard selection) and at the level of local, spatially distinct patches (soft selection)-on the emergence and fate of diversity under strong divergent selection. We find that while the form of population regulation has ...
