Ultralow Threshold, Single-Mode InGaAs/GaAs Multiquantum Disk Nanowire Lasers.

ACS Nano 2021 May 10;15(5):9126-9133. Epub 2021 May 10.

Department of Electronic Materials Engineering, Research School of Physics, The Australian National University, Canberra, Australian Capital Territory 2601, Australia.

We present single-mode nanowire (NW) lasers with an ultralow threshold in the near-infrared spectral range. To ensure the single-mode operation, the NW diameter and length are reduced specifically to minimize the longitudinal and transverse modes of the NW cavity. Increased optical losses and reduced gain volume by the dimension reduction are compensated by an excellent NW morphology and InGaAs/GaAs multiquantum disks. Read More

Shandong Key Laboratory of Biological Evaluation for Medical Devices, NMPA Key Laboratory for Safety Evaluation of Biomaterials and Medical Devices, NMPA Key Laboratory for Quality Control of Pharmaceutical Packaging, Shandong Quality Inspection Center for Medical Devices, China.

Sodium carboxy methyl cellulose (SCMC) is an important absorbable biomaterial for anti-adhesion and hemostasis medical devices used in the abdominal cavity. However, the systemic toxicity of SCMC following intraperitoneal route has not been revealed sufficiently. Three SCMC solutions with gradient concentrations were intraperitoneally injected into 3 groups of rats with the doses of 50 mg/kg, 320 mg/kg and 2000 mg/kg respectively all at once to observe the dose-dependence of systemic reactions of SCMC and 10 rats (5 rats per sex) of each group were sacrificed 3 days, 7 days, 28 days and 90 days after injection to evaluate the time-dependence of the reactions.

Hollow carbon nanocapsules-based nitrogen-doped carbon nanofibers with rosary-like structure as a high surface substrate for impedimetric detection of Pseudomonas aeruginosa.

Talanta 2021 Feb 24;223(Pt 1):121700. Epub 2020 Sep 24.

Department of Chemistry, Ilam University, PO. Box 69315-516, Ilam, Iran.

The design of hollow mesoporous carbon-based materials has attracted tremendous attention, due to their sizeable intrinsic cavity to load specific chemical and unique physical/chemical properties in various applications. Herein, we have established an effective strategy for the preparation of novel hollow carbon nanocapsules-based nitrogen-doped carbon nanofibers (CNCNF) with rosary-like structure. By embedding ultrafine hollow carbon nanocapsules into electrospun polyacrylonitrile (PAN) skeleton, the as-designed composite CNFs were carbonized into hierarchical porous CNFs, consisted of interconnected nitrogen-doped hollow carbon nanocapsules.

Seismic sensitivity and bone conduction mechanisms enable extratympanic hearing in salamanders.

J Exp Biol 2020 12 21;223(Pt 24). Epub 2020 Dec 21.

Department of Biology, University of Maryland, College Park, MD 20742, USA.

The tympanic middle ear is an adaptive sensory novelty that evolved multiple times in all the major terrestrial tetrapod groups to overcome the impedance mismatch generated when aerial sound encounters the air-skin boundary. Many extant tetrapod species have lost their tympanic middle ears, yet they retain the ability to detect airborne sound. In the absence of a functional tympanic ear, extratympanic hearing may occur via the resonant qualities of air-filled body cavities, sensitivity to seismic vibration, and/or bone conduction pathways to transmit sound from the environment to the ear.

By the Skin of Your Teeth: A Subcutaneous Mouse Model to Study Pulp Regeneration.

Methods Mol Biol 2021 ;2206:223-232

Faculty of Medicine and Life Sciences, Biomedical Research Institute (BIOMED), UHasselt - Hasselt University, Diepenbeek, Belgium.

Exiting developments in tissue engineering and new insights in stem cell biology have led to new possible strategies for the regeneration of damaged tissues in the oral cavity. The regeneration of the pulp-dentin complex regeneration in particular, has drawn the attention of many researchers because of the high clinical needs. While it is still important to perform in vitro research using a wide variety of cells, scaffolds and growth factors, it is also critical to have a reliable animal model for preclinical trials.

Oral and pre-absorptive sensing of amino acids relates to hypothalamic control of food intake in rainbow trout.

J Exp Biol 2020 09 6;223(Pt 17). Epub 2020 Sep 6.

Lucta S.A., Innovation Division, UAB Research Park, 08193 Bellaterra, Spain.

To assess the putative role of taste and pre-absorptive sensing of amino acids in food intake control in fish, we carried out an oral administration with l-leucine, l-valine, l-proline or l-glutamic acid in rainbow trout (). Treatment with proline significantly reduced voluntary food intake at 2 h and 3 h after oral administration, while glutamic acid showed a less pronounced satiating effect at 3 h. The mRNA expression of taste receptor subunits , , and was measured in the epithelium overlying the bony basihyal of the fish (analogous to the tetrapod tongue) at 10, 20 or 30 min following treatment.

Antibiotic administration reduces the rate of intraamniotic inflammation in preterm prelabor rupture of the membranes.

Am J Obstet Gynecol 2020 07;223(1):114.e1-114.e20

Perinatology Research Branch, Division of Obstetrics and Maternal-Fetal Medicine, Division of Intramural Research, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, US Department of Health and Human Services, Bethesda, MD, and Detroit, MI; Department of Obstetrics and Gynecology, Wayne State University School of Medicine, Detroit, MI; Department of Obstetrics and Gynecology, University Hospital Hradec Kralove, Charles University, Faculty of Medicine, Hradec Kralove, Czech Republic.

Background: Preterm prelabor rupture of the membranes (PPROM) is frequently complicated by intraamniotic inflammatory processes such as intraamniotic infection and sterile intraamniotic inflammation. Antibiotic therapy is recommended to patients with PPROM to prolong the interval between this complication and delivery (latency period), reduce the risk of clinical chorioamnionitis, and improve neonatal outcome. However, there is a lack of information regarding whether the administration of antibiotics can reduce the intensity of the intraamniotic inflammatory response or eradicate microorganisms in patients with PPROM.
