OBJECTIVE: The staging system of Meniere's disease utilizes audiograms to probe cochlear dysfunction. We explored the addition of galvanic vestibular-evoked myogenic potentials (VEMP) to further explore vestibular function. METHODS: Seventy patients with unilateral Meniere's disease were enrolled in this study. Within 2weeks of diagnosis, all subjects underwent pure tone audiometry, cervical and ocular VEMP, and caloric test. The prevalence of abnormal tests and the VEMP characteristic parameters such as latencies and amplitudes were analyzed...

BACKGROUND: Hernia repair represents about 25% of all pediatric surgeries. Repair can be done using an open or laparoscopic technique. The open approach has a reported recurrence rate of 1.2% but requires an additional incision to repair for a contralateral hernia. With the laparoscopic approach, no additional incision is needed but the recurrence rate has been reported to be as high as 4%. The objective of this study was to assess the safety and efficacy of a novel sutureless laparoscopic inguinal hernia repair that has the advantages of both approaches...

Immobilization induces oxidative damage to the brain. Ilex paraguariensis extracts (Mate) and chlorogenic acid (CGA), its major natural compound, exert protective effects against reactive oxygen species (ROS) formation. Here, the effects of Mate and CGA on oxidative damage induced by chronic immobilization stress (CIS) in cortex (CTX), hippocampus (HIP) and striatum (STR) were investigated. For CIS, animals were immobilized during 6 h every day for 21 consecutive days. Rats received Mate or CGA daily by intra-gastric gavage 30 min before every restraint session...

Since its inception, conservation biology has inspired thousands of students, spurred the creation of new initiatives, organizations and agencies, and informed conservation efforts worldwide. Nevertheless, global biodiversity loss is accelerating (Butchart et al. 2010), and our field needs to change to keep pace with mounting challenges. Conservation would benefit if scientists more enthusiastically pushed the institutional boundaries of our field through their efforts to expand their own and others' career options and professional opportunities...

Transcriptional repression involves a class of proteins called corepressors that link transcription factors to chromatin remodeling complexes. In plants such as Arabidopsis thaliana, the most prominent corepressor is TOPLESS (TPL), which plays a key role in hormone signaling and development. Here we present the crystallographic structure of the Arabidopsis TPL N-terminal region comprising the LisH and CTLH (C-terminal to LisH) domains and a newly identified third region, which corresponds to a CRA domain. Comparing the structure of TPL with the mammalian TBL1, which shares a similar domain structure and performs a parallel corepressor function, revealed that the plant TPLs have evolved a new tetramerization interface and unique and highly conserved surface for interaction with repressors...

In this study, we demonstrate a rapid treatment method for producing a needle-like nanowire structure on a hot-dip galvanized sheet at a temperature of 50 °C. The processing method involved only supercritical carbon dioxide and water to induce a reaction on the zinc surface, which resulted in growth of zinc hydroxycarbonate nanowires into flower-like shapes. This artificial patina nanostructure predicts high surface area and offers interesting opportunities for its use in industrial high-end applications. The nanowires can significantly improve paint adhesion and promote electrochemical stability for organic coatings, or be converted to ZnO nanostructures by calcining to be used in various semiconductor applications...

Two unlike metals near one another can break down as they move toward electrochemical equilibrium resulting in galvanic corrosion. We describe a case of electrochemical corrosion resulting in pseudarthrosis, followed by instrumentation failure leading to subarachnoid hemorrhage. A 53-year-old female with a history of cervical instability and two separate prior cervical fusion surgery with sublaminar cables presented with new onset severe neck pain. Restricted range of motion in her neck and bilateral Hoffman's was noted...

The role of the class IIa bacteriocin membrane receptor protein remains unclear and two different mechanisms have been proposed: the bacteriocin could interact with the receptor changing it to an open conformation or the receptor might act as an anchor allowing subsequent bacteriocin insertion and membrane disruption. Bacteriocin-producing cells synthesize an immunity protein that forms an inactive bacteriocin-receptor-immunity complex. To better understand the molecular mechanism of enterocin CRL35, the peptide was expressed as the suicidal probe EtpM-enterocin CRL35 in Escherichia coli, a naturally insensitive microorganism since it does not express the receptor...

People who work in health care facilities participate in a shared set of tacit agreements, attitudes, habits, and behaviors that contribute to the functioning of those institutions, but that can also cause conflict. This phenomenon has been addressed tangentially in the study of bureaucratic practices in governmental agencies, but it has not been carefully explored in the specific context of public health care centers. To this end, we analyzed a series of encounters among staff and patients, as well as the situations surrounding the services offered, in public primary care health centers in Mexico City, based on Erving Goffman's concepts of social order, encounter, and situation, and on the concepts of formal and informal logic...

Drowning, a common cause of death in the pediatric population, is a potentially large donor pool for OLT. Anecdotally, transplant centers have deemed these organs high risk over concerns for infection and graft dysfunction. We theorized drowned donor liver allografts do not portend worse outcomes and therefore should not be excluded from the donation pool. We reviewed our single-center experience of pediatric OLTs between 1988 and 2015 and identified 33 drowned donor recipients. These OLTs were matched 1:2 to head trauma donor OLTs from our center...
