Lincomycin forms cross-links within the peptidyl transferase loop region of the 23S ribosomal RNA (rRNA) of the 50S subunit of the bacterial ribosome, which is the site of peptide bond formation, thereby inhibiting protein synthesis. We have previously reported that lincomycin at concentrations below the minimum inhibitory concentration potentiates the production of secondary metabolites in actinomycete strains, suggesting that activation of these strains by utilizing the dose-dependent response of lincomycin could be used to effectively induce the production of cryptic secondary metabolites...

Objective: To assess the efficacy and safety of high-flow nasal oxygen (HFNO) therapy in patients undergoing rapid sequence intubation (RSI) for emergency abdominal surgery. Methods: HFNO of 60 L.min-1 at an inspiratory oxygen fraction of 1 was delivered 4 min before laryngoscopy and maintained until the patient was intubated, and correct intubation was verified by the appearance of the end-tidal CO2 (EtCO2) waveform. Transcutaneous oxygenation (SpO2), heart rate and non-invasive mean arterial pressure were monitored at baseline (T0), after 4 min on HFNO (T1) and at the time of laryngoscopy (T2) and endotracheal intubation (ETI) (T3)...

BACKGROUND: Cucumber downy mildew is among the most important diseases that can disrupt cucumber production. Propamocarb, also known as propyl-[3-(dimethylamino)propyl]carbamate (PM), is a systemic carbamate fungicide pesticide that is widely applied in agricultural production because of its high efficiency of pathogens control, especially cucumber downy mildew. However, residual PM can remain in cucumbers after the disease has been controlled. To explore the molecular mechanisms of PM retention, cucumber cultivars 'D9320' (with the highest residual PM content) and 'D0351' (lowest residual PM content) were studied...

Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) can prolong apnoea time in adults. Therefore, THRIVE used for pre-oxygenation in rapid sequence induction of anaesthesia could extend safe apnoea time during prolonged laryngoscopy and intubation. In this randomised controlled trial, we compared the lowest peripheral oxygen saturation (SpO2 ) during intubation when pre-oxygenating with either traditional facemask or THRIVE. Eighty adult patients, undergoing rapid sequence induction of anaesthesia for emergency surgery, were randomly allocated to pre-oxygenation with 100% oxygen with facemask or with THRIVE...

Results using videolaryngoscopy in pre-hospital rapid sequence intubation are mixed. A bougie is not commonly used with videolaryngoscopy. We hypothesised that using videolaryngoscopy and a bougie as core elements of a standardised protocol that includes a drugs and a laryngoscopy algorithm would result in a high first-pass tracheal intubation success rate. We employed videolaryngoscopy (C-MAC) combined with a bougie (Frova intubating introducer) in an anaesthetist-staffed helicopter emergency medical service...

Context: Laryngoscopy and intubation performed during RSI lead to choroidal blood volume increase and an eventual rise in intraocular pressure (IOP). Use of succinylcholine (SCh) causes an undesirable rise in IOP which is further aggravated by laryngoscopy and endotracheal intubation. Dexmedetomidine is a highly selective centrally acting α2 adrenergic agonist that has IOP lowering properties. Aims: This study aims to evaluate the efficacy of intravenous (i.v.) infusion of dexmedetomidine (0...

Expression of the cell surface glycoprotein MHC class I polypeptide-related sequence A (MICA) is induced in dangerous, abnormal or 'stressed' cells, including cancer cells, virus-infected cells and rapidly proliferating cells. MICA is recognized by the activating immune cell receptor NKG2D, providing a mechanism by which immune cells can identify and potentially eliminate pathological cells. Immune recognition through NKG2D is implicated in cancer, atherosclerosis, transplant rejection and inflammatory diseases such as rheumatoid arthritis...

Toll-like receptors (TLRs) are important components of innate immunity. TLRs recognize pathogen-associated molecular patterns (PAMPs) and initiate downstream signaling pathways in response. In present study, we report the identification of two TLRs from gibel carp (Carassius auratus gibelio), TLR2 and TLR3 (designated CagTLR2 and CagTLR3, respectively). We report on the genomic structures and mRNA expression patterns of CagTLR2 and CagTLR3. Five exons and four introns were identified from the genomic DNA sequence of CagTLR3 (4749 bp in total length); this genomic organization is similar to that of TLR3 in zebrafish and human...

Cymbidium, one of the most important orchid genera in horticulture, can be classified into epiphytic and terrestrial species. Generally, epiphytic Cymbidium seedlings can be easily propagated by tissue culture, but terrestrial seedlings are difficult to propagate. To date, the molecular mechanisms underlying the differences in the ease with which terrestrial and epiphytic cymbidiums can be propagated are largely unknown. Using RNA-sequencing, quantitative reverse transcription PCR and enzyme-linked immunosorbent assay, Cymbidium 'Xiaofeng' (CXF), which can be efficiently micropropagated, and terrestrial Cymbidium sinense 'Qijianbaimo' (CSQ), which has a low regeneration ability, were used to explore the molecular mechanisms underlying the micropropagation ability of Cymbidium species...

Rocuronium is commonly used in preference to suxamethonium for rapid sequence induction in the Intensive Care Unit (ICU). We describe a patient who suffered significant neck trauma following a suicide attempt. On initial presentation to accident and emergency, he was an easy intubation with a Grade 1 view obtained at laryngoscopy. After surgery to repair his neck laceration, he was extubated and discharged from ICU. He later developed a severe aspiration pneumonia and required reintubation. After induction and paralysis with suxamethonium, the best view at laryngoscopy was a Grade 3 despite the use of different laryngoscopes...

Although viruses and viral capsids induce rapid immune responses, little is known about viral pathogen-associated molecular patterns (PAMPs) that are exhibited on their surface. Here, we demonstrate that the repeating protein subunit pattern common to most virus capsids is a molecular pattern that induces a Toll-like-receptor-2 (TLR2)-dependent antiviral immune response. This early antiviral immune response regulates the clearance of subsequent bacterial superinfections, which are a primary cause of morbidities associated with influenza virus infections...

Background: Resistance to platinum-based chemotherapy is a clinical challenge in the treatment of ovarian cancer (OC) and limits survival. Therefore, innovative drugs against platinum-resistance are urgently needed. Our therapeutic concept is based on the conjugation of two chemotherapeutic compounds to a monotherapeutic pro-drug, which is taken up by cancer cells and cleaved into active cytostatic metabolites. We explore the activity of the duplex-prodrug 5-FdU-ECyd, covalently linking 2'-deoxy-5-fluorouridine (5-FdU) and 3'-C-ethynylcytidine (ECyd), on platinum-resistant OC cells...

Autumn Riddell
Apneic oxygenation during intubation is the application of oxygen via a nasal cannula, which is left in place throughout laryngoscopy. The flow rate of oxygen is set to at least 15 L/min and theoretically reduces the risk of oxygen desaturation and hypoxemia during the procedure. Over the last 5 years, there have been several studies published on this topic with differing results. Despite conflicting results, use of apneic oxygenation is becoming more prevalent and is being implemented into standard operating procedures in some clinical settings...

Prenatal exposure to the antiepileptic, mood-stabilizing drug, valproic acid (VPA), increases the incidence of autism spectrum disorders (ASDs); in utero administration of VPA to pregnant rodents induces ASD-like behaviors such as repetitive, stereotyped activity, and decreased socialization. In both cases, males are more affected than females. We previously reported that VPA, administered to pregnant mice at gestational day 12.5, rapidly induces a transient, 6-fold increase in BDNF (brain-derived neurotrophic factor) protein and mRNA in the fetal brain...

We present a case that highlights the issues surrounding the delivery of a safe general anaesthetic to a patient with Huntington's disease (HD) and bulbar dysfunction. In the case of a 46-year-old patient undergoing laparoscopic percutaneous endoscopic gastrostomy tube insertion, we discuss the rationale behind our chosen method and anaesthetic agents as well as airway issues specific to HD. In a patient whose condition would not allow for an awake fibreoptic intubation, we opted for a modified rapid sequence induction...
