Tissue-resident macrophages shape the development and homeostasis of the organs that they colonize. Yu et al. (2017) demonstrate that, unique to the lung, the instructive cytokine TGF-β collaborates with GM-CSF to induce the master transcription factor PPARγ to drive alveolar macrophage differentiation and maintenance early in life.

BACKGROUND: It has been hypothesized that life threatening events are caused by supra-esophageal reflux (SER) of gastric contents which activates laryngeal chemoreflex-stimulated apnea. Placing infants supine decreases the risk of sudden infant death syndrome (SIDS). The aim of this study was to determine whether body position affects esophageal reflexes that control SER. METHODS: We instrumented the pharyngeal and esophageal muscles of decerebrate cats (N=14) to record EMG or manometry, and investigated the effects of body position on the esophago-upper esophageal sphincter (UES) contractile reflex (EUCR), esophago-UES relaxation reflex (EURR), esophagus-stimulated pharyngeal swallow response (EPSR), secondary peristalsis (SP), and pharyngeal swallow (PS)...

BACKGROUND: Questions persist regarding the general applicability of the Furlow palatoplasty technique, and thus, widespread adoption of its use has been uneven. This study describes a consecutive, nonselective series of primary Furlow palatoplasties. Highlighted is the unique fact that plastic surgical residents functioned as the primary surgeon for all steps of all procedures throughout the series. METHODS: A retrospective review was undertaken of all primary palatoplasties performed under the direction of the senior surgeon between December 2005 and April 2012...

Optimal wound healing with negative pressure wound therapy (NPWT) relies on a properly sealed vacuum system. Anatomically difficult wounds impair the adhesive dressing, which results in air leaks that disrupt the integrity of the NPWT system and hinder wound healing. OBJECTIVE: The authors demonstrate a new technique using a cyanoacrylate-based tissue adhesive to maintain an airtight, durable seal in NPWT. MATERIALS AND METHODS: A 52-year-old woman with a degloving injury to the right thigh extending into the groin, resulting in massive necrosis, presented to the emergency department...

Coherent anti-Stokes Raman spectroscopy (CARS) is a sensitive technique for probing highly luminous flames in combustion applications to determine temperatures and species concentrations. CARS thermometry has been demonstrated for the vibrational Q-branch and pure-rotational S-branch of several small molecules. Practical advantages of pure-rotational CARS, such as multi-species detection, reduction of coherent line mixing and collisional narrowing even at high pressures, and the potential for more precise thermometry, have motivated experimental and theoretical advances in S-branch CARS of nitrogen (N2), for example, which is a dominant species in air-fed combustion processes...

Background: Epidemiological studies link ambient fine particulate matter (PM2.5) pollution to abnormalities in the male reproductive system. However, few toxicological studies have investigated this potentially important adverse effect of PM2.5 pollution. Therefore, in the present study, we analyzed the effects of PM2.5 exposure on spermatogenesis and hypothalamic-pituitary- gonadal (HPG) axis in a murine model. Methods: Fourteen male C57BL/6J mice were subjected to a 4-month exposure to filtered air (FA) or concentrated ambient PM2...

The food matrix is a limiting factor in determining the bioaccessibility of carotenoids. The impact of food matrix change on the bioaccessibility of carotenoids during drying processes is still unknown. The effect of intermittent microwave vacuum-assisted drying (IMVD) and hot air drying (HAD) on the in vitro liberation and micellization of carotenoids in pumpkin slices was studied. This variable depended on the changes of the matrix driven by the drying process. Different changes in the cell morphology and carotenoid distribution of pumpkin slices during the two processing methods were observed...

The easy to prepare and stable in air (2-methylimidazolium) tetraiodoantimoniate(iii) single-crystals with optical band gap of 2.17(1) eV at room temperature have been synthesized. The crystal structure features one-dimensional [SbI4](-)n anionic chains, which are intercepted with stacks of 2MIm(+) ions. At 294/295 K, it undergoes a structural phase transition to an incommensurately modulated phase as a result of subtle, lone-pair-electron-driven distortions of the anions. Separately from the anion displacements, the ordering of 2MIm(+) countercations takes place over a wide temperature range of the modulated phase...
