The potency of Ludwigia adscendens and L. octovalvis as phytoremediator macrophytes in Indonesia was reviewed. The characteristics of these species might be essential information for operators who wanted to implement phytoremediation in their sites. Information and articles about these species in Indonesia was collected through Google-Scholar during the first week of February 2021 and reviewed. Many studies about phytoremediation focused only on the capabilities of macrophytes to remove contaminants from water and paid only little attention to their compatibility with the ecosystem leading to upset the ecosystem. To Indonesia, these two species were introduced and became weeds, with different ecological characteristics. In Indonesia, scarce phytoremediation studies using these species were detected. Therefore, although these species were classified as weeds it was, remained, worthwhile to investigate further these species to be used in the phytoremediation of water.

An understanding of the specific interactions of actin with regulatory proteins has been limited by the lack of information about the structure of the actin filament. Molecular actin has been studied in actin-DNase I complexes by single crystal X-ray analysis, to a resolution of about 0.6nm, and in the electron microscope where two dimensional actin sheets have been reconstructed to a maximum resolution of 1.5nm. While these studies have shown something of the structure of individual actin molecules, essential information about the orientation of actin in the filament is still unavailable.The work of Egelman & DeRosier has, however, suggested a method which could be used to provide an initial quantitative estimate of the orientation of actin within the filament. This method involves the quantitative comparison of computed diffraction data from single actin filaments with diffraction data derived from synthetic filaments constructed using the molecular model of actin as a building block. Their preliminary work was conducted using a model consisting of two juxtaposed spheres of equal size.

Loud music and noisy hobbies are part of our cultural landscape. These activities can be enjoyed with minimal risk to hearing if a few commonsense guidelines are followed. Educating clients about risks and protective strategies will empower them to make informed decisions about their hearing health that best reflect their values and priorities. In this article, the author covers essential information to avoiding noise-induced hearing loss, writing in easily accessible language to better help clinicians convey this information to their clients.

The purpose of this article is to provide background information and the current understanding of a less familiar cause of female breast cancer; exposure to ultraviolet light at night. Breast cancer is a common disease that causes significant morbidity and mortality in women. There are several risk factors for breast cancer, most of which are genetic and environmental in nature. An often-overlooked risk factor is exposure to blue light during night shift work, which decreases melatonin production. One of the many cancer-preventing properties of melatonin is to limit estrogen production. Increased lifetime exposure to estrogen is a well-known cause of breast cancer. Awareness of nighttime blue light exposure as a breast cancer risk factor by women doing night shift work and those exposed to nighttime light via smartphones and laptops, is essential information to know so that protective measures can be taken.
