A malignant wheeze!

Asthma is a common disorder presenting with nonspecific features, which may mimic other conditions such as tracheal tumors. Tracheal tumors are often misdiagnosed as asthma. We report a case of a 38-year female who was being worked up for persistent wheeze that was initially attributed to acute asthma, only to be later discovered as tracheal tumor. A high index of suspicion for alternative diagnoses must be kept in mind while evaluating a patient who presents with clinical features suggestive of asthma, but fails to respond to standard therapy. The present case report emphasizes the fact that not all wheezes are asthma

Characterization of some naphthalene using bacteria isolated from contaminated Cooum Riverine sediment of the Bay of Bengal (India)

Microorganisms capable of using naphthalene as the sole carbon source were isolated from the contaminated sediment of Cooum River. Twenty one isolates were recovered and nine were selected for enrichment due to differences in their morphological characteristics. Out of nine isolates, only four (NS3-SRMND14B, NS14-SRMND14A, NS15-SRMND14D and NS19- -SRMND14E) were capable of completely utilizing naphthalene as the sole source of carbon in carbon free minimal medium (CFMM) supplemented with naphthalene. 16S rDNA sequencing showed that all the four isolates were distantly related to each other and belongs to Bacillus sp. (NS3-SRMND14B), Pseudomonas sp. (NS14-SRMND14A), Cellulosimicrobium sp. (NS15-SRMND14D) and Sphingobacterium sp. (NS19-SRMND14E), respectively. Based on the phylogenetic analysis of 16S rDNA sequencing, the isolate Sphingobacterium sp. (NS19-SRMND14E) has been identified as novel strain. Polymerase chain reaction (PCR) technique showed the presence of naphthalene dioxygenase (ndo) gene responsible for naphthalene degradation only in the Pseudomonas sp. (NS14-SRMND14A). We observed that the ndo gene is not the only gene responsible for naphthalene degradation. Based on our study, the indigenous microorganisms isolated from Cooum Riverine sediment can be used for bioremediation of the polluted sediment along the Bay of Bengal.Supplementary material: [http://cherry.chem.bg.ac.rs/handle/123456789/3840

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM
