Abstract:

ABSTRACT Kardashev Type III civilisations have by definition energy requirements that are likely to generate strong excess emission in the mid-infrared (MIR) that is associated with the waste heat they generate. For those civilisations that capture starlight via Dyson sphere like constructions, the Optical to MIR flux ratio of the host galaxies is also expected to be unusually low. Since a wide range of galaxy types adhere to the infrared-radio correlation (IRC), galaxies hosting Type III civilisations should also strongly deviate from this relation. Radio data can therefore play a crucial rol

Abstract:

MicroRNAs (miRNAs) are short non-coding RNAs (20–25 nucleotides in length) capable of regulating gene expression by binding -fully or partially- to the 3’-UTR of target messenger RNA (mRNA). To date, several studies have investigated the role of sperm miRNAs in spermatogenesis and their remaining presence toward fertilization and early embryo development. However, little is known about the miRNA cargo in the different sperm sources and their possible implications in boar fertility. Here, we characterized the differential abundance of miRNAs in spermatozoa from the terminal segment of the epidi

Abstract:

Abstract We numerically studied coherent mid-infrared (MIR) supercontinuum (SC) generated by filling carbon chloride (CCl4, C2Cl4) into the tapered photonic crystal fiber (PCF). The mechanism involves nonlinear soliton compression, Raman soliton self-frequency shift and dispersive wave generated in a carbon chloride core tapered PCF pumped by a 1.98 μm femtosecond laser. Numerical solution of the generalized nonlinear Schrodinger equation shows that 1.15–5.5 μm (CCl4-core tapered PCF) and 1.15–5.7 μm (C2Cl4-core tapered PCF) coherent MIR-SC sources can be realized.

The review article describes the involvement of epigenetic factors in type 1 diabetes mellitus (T1DM) etiopathogenesis. The disease is characterized by changes in expression of microRNAs that affect the transcription of genes involved in autoimmune reactions, destruction of beta cells and insulin production. However, the cause of the observed epigenetic changes is still unclear. In evolution, the sources of microRNA genes are transposable elements, which occupy up to 45 % of the entire human DNA sequence and are drivers of epigenetic regulation in ontogenesis. They are sources of transcription

Abstract:

Abstract Mid-infrared (MIR) emission from tidal disruption events (TDEs) is a powerful probe of the circumnuclear environment around dormant supermassive black holes. This emission arises from the reprocessing of intrinsic emission into thermal MIR emission by circumnuclear dust. While the majority of optical- and X-ray-selected TDEs show only weak dust echoes consistent with primarily unobscured sight lines, there have been growing efforts aimed at finding TDEs in obscured environments using MIR selection methods. In this work, we present the first JWST observations of four MIR-selected TDEs

CD34+ cells are potential cells sources because these cells can differentiate into cardiomyocytes through several mechanisms.

During animal development, SDF1 simultaneously guides various cell types to different targets. As many targets are in close proximity to one another, it is unclear how the system avoids mistargeting. Zebrafish trigeminal sensory neurons express the SDF1 receptor Cxcr4b and encounter multiple SDF1 sources during migration, but ignore all but the correct one. We show that miR-430 and Cxcr7b regulation of SDF1a are required for precise guidance. In the absence of miR-430 or Cxcr7b, neurons responded to ectopic SDF1a sources along their route and did not reach their target. This was due to a failu

Abstract. The Physikalisch-Technische Bundesanstalt (PTB) expanded its capabilities of the absolute measurement of radiant power to the spectral range of the mid-infrared (MIR) by implementing additional MIR laser radiation sources at one of the PTB's cryogenic electrical substitution radiometer facilities. This extension enables absolute calibrations of the spectral responsivity of detectors in the MIR traceable to the International System of Units (SI). The thermopile detector TS-76 was characterized and calibrated in view of its spectral responsivity s(λ) in the wavelength range between 1.5

Abstract:

A fully transportable laser heterodyne radiometer (LHR), involving a flexible polycrystalline mid-infrared (PIR) fiber-coupling system and operating around 8 µm, was characterized and optimized with the help of a calibrated high temperature blackbody source to simulate solar radiation. Compared to a mid-IR free-space sunlight coupling system, usually used in a current LHR, such a fiber-coupling system configuration makes the mid-infrared (MIR) LHR fully transportable. The noise sources, heterodyne signal, and SNR of the MIR LHR were analyzed, and the optimum operating local oscillator (LO) pho

Abstract:

Farm procedures have an impact on animal welfare by activating the hypothalamic-pituitary-adrenal axis that induces a wide array of physiological responses. This adaptive system guarantees that the animal copes with environmental variations and it induces metabolic and molecular changes that can be quantified. MicroRNAs (miRNAs) play a key role in the regulation of homeostasis and emerging evidence has identified circulating miRNAs as promising biomarkers of stress-related disorders in animals. Based on a clustering analysis of salivary cortisol trends and levels, 20 ewes were classified into

Formaldehyde (HCHO) is a toxic compound and plays an important role in atmospheric chemical reactions as a source of radicals and precursor of oxidants (mainly ozone). HCHO generates from primary sources (motor vehicles) and secondary sources (photochemical reactions). However, carbonyl compounds monitoring and research on their roles in chemical reaction (ozone production) in Indonesia is still limited. This research investigated the contribution and relationship of hydrocarbons (formaldehyde) and ozone in urban areas. Formaldehyde measurements were carried out for two weeks using absorption

Methods 40 fetuses with spina bifida and 46 control fetuses from Shanxi Province in China were enrolled to study miR-324–5p alternations with folate deficiency.

Cardiovascular diseases (CVDs) are widely recognized as the leading cause of mortality worldwide.

These vesicles are suggested as complementary prospective biomarkers of CVDs; however, the role of exosomes in CVDs is still not fully elucidated.

Abstract:

Malignant pleural mesothelioma (MPM) is an incurable cancer of the pleura that can be difficult to diagnose. Biomarkers for an easier and/or earlier diagnosis are needed. Approximately 90% of MPM patients develop a pleural effusion (PE). PEs are ideal sources of biomarkers as the fluid would almost always require drainage for diagnostic and/or therapeutic reasons. However, differentiating MPM PE from PE caused by other diseases can be challenging. MicroRNAs are popular biomarkers given their stable expression in tissue and fluid. MicroRNAs have been analysed in PE cytology samples for the diag

We cross-correlated these 260 sources with other catalogs at different wavelengths (APM, SDSS DR10, VCV-13, BZCAT, 2MASS, and WISE).

Idiopathic pulmonary fibrosis (IPF) is a severe progressive interstitial lung disease with a prevalence of 2 to 29 per 100,000 of the world’s population.

The pathogenesis of IPF consists of TGF-β activation, epithelial-mesenchymal transition, and SIRT7 expression decrease.
