The biophysical basis of bacterial colony growth.

Bacteria often attach to surfaces and grow densely-packed communities called biofilms. As biofilms grow, they expand across the surface, increasing their surface area and access to nutrients. Thus, the overall growth rate of a biofilm is directly dependent on its "range expansion" rate.

Epidemiological investigation of a cholera outbreak in Nepal-India border communities: Public health implications.

Objectives: On October 4, 2021, a cholera outbreak was reported in Kapilvastu District, one of Nepal's 26 districts bordering India. This study examined the outbreak's characteristics, response efforts, and the challenges faced.

Methods: A descriptive cross-sectional design was applied for the outbreak investigation.

Kamchatka (southeastern Siberia) ice core records of dicarboxylic acids, oxocarboxylic acids and α-dicarbonyls since 1690s: A signal for the tropospheric oxidizing capacity.

There has been much interest about how to identify an ice core signal for oxidizing capacity of the troposphere. This study broadly explains the air-snow transfer/deposition process using ice core records of dicarboxylic (DCAs), ω-oxocarboxylic as well as pyruvic acids and α-dicarbonyls, which are potentially formed by atmospheric oxidation of aromatic hydrocarbons from the continent, incloud-oxidation of isoprene and unsaturated fatty acids from the western North Pacific. An ice core (~152 m long, 304 years) was collected at an ice cap on the Gorshkov crater at the summit of Ushkovsky (56° 04'N, 160° 28'E, altitude: 3903 m) in the Kamchatka Peninsula from southeastern Siberia.

Precipitate, preterm labor in acute organophosphate poisoning in pregnancy: a case report.

Introduction: Acute organophosphorus poisoning (AOPP) during pregnancy is uncommon. When complicated by preterm labor, it presents therapeutic dilemmas due to the lack of established guidelines.

Case Presentation: The authors describe a case of a 19-year-old primigravida at 33 weeks of gestation with AOPP.
