BACKGROUND: The challenge of knowledge translation in medical settings is well known, and implementing change in clinical practice can take years. For the increasing number total knee arthroplasty (TKA) patients annually, there is ample evidence to endorse neuraxial anesthesia over general anesthesia. The rate of adoption of this practice, however, is slow at the current time. We hypothesized that a Perioperative Surgical Home (PSH) model facilitates rapid change implementation in anesthesia...

BACKGROUND: Surgical Outreach for the Americas is a 501(c)3 nonprofit organization providing surgical care to those in need in developing countries of the Western Hemisphere. Every year since its inception in 2008, teams of surgeons, nurses, and allied health professionals have traveled to areas of need and performed primarily hernia repair surgeries for those without access to affordable health care. METHODS: Surgical Outreach for the Americas (SOfA) began as a general concept based on World Health Organization statistics claiming that 11% of the global burden of disease can be resolved via surgery...

BACKGROUND: Hepatic resection is a major surgical procedure. Data on outcomes of hepatectomy in Saudi Arabia are scarce. OBJECTIVE: To measure morbidity and mortality and assess predictors of outcome after hepatectomy. DESIGN: Descriptive study. SETTING: Tertiary care center in Saudi Arabia with well established hepatobiliary surgery unit. PATIENTS AND METHODS: All patients undergoing liver resection in our institute during 2006-2014...

Existing implantable stimulators use powering approaches that result in stiff and bulky systems or result in systems incapable of producing the current magnitudes required for neuromuscular stimulation. This hampers their use in neuroprostheses for paralysis. We previously demonstrated an electrical stimulation method based on electronic rectification of high frequency (HF) current bursts. The implants act as rectifiers of HF current that flows through the tissues by galvanic coupling, transforming this current into low frequency current capable of performing neuromuscular stimulation...

INTRODUCTION: Low and middle income countries bear a disproportionate burden of paediatric morbidity and mortality. South Africa, a middle income country, has unacceptably high mortality in children less than 5 years of age. Many factors that contribute to the child mortality rate are time sensitive and require efficient access to emergency care. Delays and barriers within the emergency medical services (EMS) system increase paediatric morbidity and mortality from time sensitive illnesses...

Anew hydrophilid genus Chimaerocyon gen. nov. containing two species, C. shimadai sp. nov. (Malaysia: Pahang) and C. sumatranus sp. nov. (Indonesia: Sumatra), is described. Specimens of C. shimadai were collected from brood cells in anest of Pheidole singaporensis Özdikmen, 2010. The biology of C. sumatranus remains unknown. A molecular phylogeny based on four genes (cox1, cox2, 18S and 28S) supports the placement of the genus as deeply nested within the Cercyon-group of the tribe Megasternini. This position is supported by the subdistal position of the median spur in the hind wing (unique to Megasternini) and the presence of sucking disc on male maxilla (unique for Megastemini+Sphaeridiini)...

OBJECTIVES: To assess the physician’s knowledge on intubation techniques and to identify the common practices. METHODS: This was a prospective study, involving three different intensive care units within a University hospital: Anesthesiology (ANEST), Pulmonology (PULMO) and Emergency Department (ED). All physicians working in these units and consenting to participate in the study completed a questionnaire with their demographic data and questions on orotracheal intubation...

INTRODUCTION: The goal of an Emergency Medical Services (EMS) system is to prevent needless death or disability from time-sensitive disease processes. Despite growing evidence that these processes contribute significantly to mortality in low- and middle- income countries (LMICs), there has been little focus on the development of EMS systems in poor countries. Problem The objective of this study was to understand the utilization pattern of a newly-implemented EMS system in Ruhiira, Uganda...

In this retrospective study, we describe the anesthetic management and its implications in parturients with chronic kidney disease (CKD; n = 9), who underwent elective caesarean delivery. Nine parturients with CKD of various etiologies, who underwent elective Caesarean delivery, were included in this study. Spinal anest-hesia was administered in all parturients with normal coagulation profile through a 25-gauze spinal needle (Quincke) with 0.5% (H) bupivacaine in L2-3 space and T6 level was achieved. Hemodynamics and side effects such as nausea, vomiting, headache, and backache were record...

Negative energy balance is a known risk factor for decreased fertility in dairy cows. This study evaluated the accuracy of plasma concentrations of nonesterified fatty acids (NEFA), β-hydroxybutyrate (BHBA), and insulin-like growth factor 1 (IGF-1)-factors related to negative energy balance-in predicting decreased fertility. One plasma sample per cow was collected from 480 cows in 12 herds during the period from d 4 to 21 in milk and analyzed for NEFA, BHBA, and IGF-1. For each cow, data on breed, parity, calving date, gynecological examinations, and insemination dates were obtained...

PURPOSE: Adverse effects by night-call duty have become an important occupational health issue. The aim of this study was to investigate whether the heart rate variability (HRV) differed during recovery from day work and night-call duty between distinct physician specialities. METHODS: We studied the impact of a 16-h night-call duty on autonomic balance, measured by HRV, among two physician groups differing with respect to having to deal with life-threatening conditions while on call...

BACKGROUND: Dermicol-P35 27G, an advanced collagen dermal filler, is effective for nasolabial fold (NLF) correction. OBJECTIVES: To compare the efficacy and tolerance of Dermicol-P35 27G premixed with lidocaine with that of Dermicol-P35 27G injected after topical anesthesia for NLF correction. MATERIALS AND METHODS: In a split-face protocol, 10 patients were injected with Dermicol-P35 27G/topical anest:esia or Dermicol-P35 27G/0.3% lidocaine...

Small RNAs targeted to gene promoters in human cells can mediate transcriptional gene silencing (TGS) by directing silent state epigenetic modifications to targeted loci. Many mechanistic details of this process remain poorly defined, and the ability to stably modulate gene expression in this manner has not been explored. Here we describe the mechanisms of establishment and maintenance of long-term transcriptional silencing of the human ubiquitin C gene (UbC). Sustained targeting of the UbC promoter with a small RNA for a minimum of 3 days resulted in long-term silencing which correlated with an early increase in histone methylation and a later increase in DNA methylation at the targeted locus...

BACKGROUND: SecTRAPs (selenium compromised thioredoxin reductase-derived apoptotic proteins) can be formed from the selenoprotein thioredoxin reductase (TrxR) by targeting of its selenocysteine (Sec) residue with electrophiles, or by its removal through C-terminal truncation. SecTRAPs are devoid of thioredoxin reductase activity but can induce rapid cell death in cultured cancer cell lines by a gain of function. PRINCIPAL FINDINGS: Both human and rat SecTRAPs killed human A549 and HeLa cells...

The objective was to determine the in vitro developmental competence of buffalo oocytes collected from abattoir-derived ovaries at various stages of the estrous cycle and follicular status. In Experiment 1, ovaries (n=476 pairs) were collected and divided into the following five groups: (a) ovaries with a corpus hemorragicum and no dominant follicle (CH-NO-DF); (b) ovaries with a mature functional corpus luteum (CL) and a dominant follicle (CL-DF); (c) ovaries with a mature functional CL and no dominant follicle (CL-NO-DF); (d) ovaries with a regressing CL and a dominant follicle (RCL-DF); and (e) ovaries without any luteal structures and only small follicles (ANEST)...

Phosphorylation of histone H3 protein at serine 10 is an important step in chromatin remodeling during transcriptional transactivation. IkappaB kinase-alpha (IKK-alpha) and Mitogen- and Stress-activated protein Kinases 1 and 2 (MSK1/2) have been shown to play key roles in the transcriptional regulation of immediate early genes such as c-fos. Interestingly, IKK-alpha and MSK1/2 have also been implicated as histone H3-Ser10 kinases. In this work, we have shown that MSK1/2 are required for epidermal growth factor (EGF)-induced, but not tumor necrosis factor-induced, histone H3-Ser10 phosphorylation, both globally and at specific promoters...

Mammalian thioredoxin reductase (TrxR) is important for cell proliferation, antioxidant defense, and redox signaling. Together with glutathione reductase (GR) it is the main enzyme providing reducing equivalents to many cellular processes. GR and TrxR are flavoproteins of the same enzyme family, but only the latter is a selenoprotein. With the active site containing selenocysteine, TrxR may catalyze reduction of a wide range of substrates, but can at the same time easily be targeted by electrophilic compounds due to the extraordinarily high reactivity of a selenolate moiety...

Mitogenic activation of expression of immediate-early genes, such as c-fos, is controlled through signal-induced phosphorylation of constitutively bound transcription factors that is correlated with a nucleosomal response that involves inducible chromatin modifications, such as histone phosphorylation and acetylation. Here we have explored a potential role for the transcription factor NF-kappaB and its associated signaling components in mediating induction of c-fos gene expression downstream of epidermal growth factor (EGF)-dependent signaling...

Extensive data indicate that the transcription factor NF kappa B is activated by signals downstream of oncoproteins such as Ras or breakpoint cluster region (BCR)-ABL. Consistent with this, evidence has been presented that NF kappa B activity is required for Ras and BCR-ABL to transform cells. However, it remains unclear whether these oncoproteins activate a full spectrum of NF kappa B-dependent gene expression or whether they may augment or interfere with other stimuli that activate NF kappa B. The data presented here indicate that BCR-ABL expression in 32D myeloid cells or oncogenic Ras expression in murine fibroblasts blocks the ability of tumor necrosis factor (TNF) to activate NF kappa B...
