Int J Syst Evol Microbiol. 2024 Apr;74(4). doi: 10.1099/ijsem.0.006312.ABSTRACTA Gram-stain-negative, aerobic, oxidase-positive, weakly catalase-positive, motile by means of a single polar flagellum, rod-shaped bacterium designated as strain S2-9T was isolated from sediment sampled in Wiyang pond, Republic of Korea. Growth of this strain was observed at 10-40 °C (optimum, 35 °C) and pH 5.5-9.5 (optimum, pH 7.0-8.0) and in the presence of 0-0.5 % NaCl in Reasoner's 2A broth. The major fatty acids (>10 %) of strain S2-9T were C16 : 0 and summed feature 3 (comprising a mixture of C16 : 1 ω7c and/or C16 : 1 ω6c). Ubiq...

Do trees respond to pollution? A network study of the impact of pollution on Spruce growth from Europe
Environ Pollut. 2024 Apr 19:124012. doi: 10.1016/j.envpol.2024.124012. Online ahead of print.ABSTRACTTree rings have been reliably used as an environmental proxy over the past decades for environmental reconstructions, simulations and forecasting. In our study, we investigated whether tree-ring chronologies are impacted by pollution. We chose sites in the Krušné hory and the Krkonoše Mountains in the Czech Republic which have a known history of pollution. We sampled Norway spruce (Picea abies [L.] Karst) in both ranges and compared their chronologies. We found no significant difference in the overall radial growth in th...

Substitution of bridge carbons for sulphur in calix[4]arene-bis- α-hydroxymethylphosphonic acid transformed mobile carrier into ionic channel accompanied with evoked muscle contraction and impaired neurotransmission powered by membrane action of resulting thiocalix[4]arene-bis-α-hydroxymethylphosphonic acid
Toxicol In Vitro. 2024 Apr 16:105815. doi: 10.1016/j.tiv.2024.105815. Online ahead of print.ABSTRACTThe action of calix[4]arenes C-424, C-425 and C-1193 has been investigated on suspended cholesterol/egg phosphatidylcholine lipid bilayer in a voltage-clamp mode. Comparative analysis with the membrane action by calix[4]arene-bis-α-hydroxymethylphosphonic acid (C-99) has shown that the substitution of bridge carbons for sulphur and addition of another methyl group to two alkyl tales in the lower rim of former dipropoxycalix[4]arene C-99 transformed mobile carrier that C-99 created in lipid bilayer (Shatursky et al., 2014) i...

Revealing cellular (poly)sulphide storage in electrochemically active sulphide oxidising bacteria using rotating disc electrodes
Bioelectrochemistry. 2024 Apr 14;158:108710. doi: 10.1016/j.bioelechem.2024.108710. Online ahead of print.ABSTRACTSulphide oxidising bacteria (SOB) have the potential to be used for bioelectrochemical removal, i.e. oxidation, of sulphide from waste streams. In anaerobic conditions, SOB are able to spatially separate sulphide removal and terminal electron transfer to an electrode and act as a sulphide shuttle. However, it is not fully understood how SOB anaerobically remove sulphide and store charge equivalents, and where in this process sulphur is formed. Therefore, the redox behaviour of sulphide shuttling SOB was investi...

From a dirty breath to atherosclerosis: Ozone pollution and neutrophil extracellular traps (NETs)
Exposure to ambient ozone in healthy individuals (shown in the magnified alveolus, including the transfer of ozone via the alveolar-capillary membrane and the contact with circulating neutrophils) associates with an elevation in the pro-atherogenic immunothrombotic pathway of NETosis. Precise mechanisms, and the role of concomitant pollutants remain unknown. Abbreviations: particulate matter (PM), ultrafine particles (UFP), sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), neutrophil extracellular traps (NETs), and red blood cells (RBC).

Cutaneous Warts Treated with Individualised Homoeopathic Medicine: A Case Series
Homœopathic Links 2024; 37: 082-093 DOI: 10.1055/s-0043-1778681Cutaneous warts are visible growths on the skin caused by infection of keratinocytes caused by the human papilloma virus. They appear in various forms on different locations on the skin and mucous membranes, the most common being hands, feet, face and neck. Despite the availability of various treatments, its persistent and recurring nature remains a matter of frustration among the medical fraternity. This case series includes eight cutaneous warts cases treated with an individualistic approach. Each case was prescribed a single medicine as per the cardinal pri...

An analytical comparison of two versions (US EPA and BIS) of pararosaniline method used for monitoring of ambient SO2
This study presents a comprehensive examination of the operational aspects of two versions of pararosaniline method employed for measuring SO2 in ambient air. The results indicate a need for redefining the specifications outlined in the BIS method. Notably, the BIS method displays greater sensitivity to low blank values compared to the EPA method. Additionally, the study introduces, for the first time, working factors and specifications associated with the BIS method for SO2 measurement. These findings suggest their potential inclusion in the standard method as a means to enhance data quality and reliability in the assessm...
