[The relationship of exudative age-related macular degeneration with lacrimal fluid chemokines in elderly patients.].

Age-related macular degeneration (AMD), along with other age-associated ophthalmologies, is a significant cause of loss of visual functions among the elderly, but the relationship of exudative AMD with lacrimal fluid chemokines has not been sufficiently studied. The aim of the work was to study the relationship of exudative AMD with lacrimal fluid chemokines in elderly patients. The content of chemokines in the lacrimal fluid was studied in 92 patients (184 eyes) 60-74 years old with exudative AMD and 84 patients (168 eyes) 60-74 years old without ophthalmopathology using a certified MAGRIX (USA) immunoassay device with Luminex technology on the xMAX platform.

Long term durability of Tc-bulk and Tc-coatings in various environmental conditions.

Technetium metal is renowned for its inertness in environmental conditions, rendering it an optimal candidate for use as a container material for high-level radioactive waste. Alternatively, thin technetium electroplated coatings can be employed to prevent corrosion of steel containers and the subsequent biofouling that may result. The utilization of metallic technetium in the design of containers for radioactive waste in deep burial may be promising from two perspectives: firstly, in terms of increasing their stability, and secondly, in terms of the utilization of technetium, which is a macrocomponent of radioactive waste.

Metagenomic evidence of a novel anammox community in a cold aquifer with high nitrogen pollution.

The process of anaerobic ammonium oxidation by nitrite (anammox) is a globally essential part of N cycle. To date, 8 Candidatus genera and more than 22 species of anammox bacteria have been discovered in various anthropogenic and natural habitats, including nitrogen-polluted aquifers. In this work, anammox bacteria were detected for the first time in the groundwater ecosystem with high anthropogenic nitrogen pollution (up to 1760 mg NO-N/L and 280 mg NH-N/L) and low year-round temperature (7-8 °C) in the zone of a uranium sludge repository.

Antitumor Effects of an Anthocyanin-Rich Grain Diet in a Mouse Model of Lewis Lung Carcinoma.

Functional foods enriched with plant polyphenol anthocyanins attract particular attention due to their health-promoting properties, including antitumor activity. We evaluated the effects of a grain diet rich in anthocyanins in a mouse model of Lewis lung carcinoma. Mice of the C57BL/6 strain were fed with wheat of near-isogenic lines differing in the anthocyanin content for four months prior to tumor transplantation.

Enhanced thermophilic high-solids anaerobic digestion of organic fraction of municipal solid waste with spatial separation from conductive materials in a single reactor volume.

Despite benefits such as lower water and working volume requirements, thermophilic high solids anaerobic digestion (THSAD) often fails due to the rapid build-up of volatile fatty acids (VFAs) and the associated drop in pH. Use of conductive materials (CM) can promote THSAD through stimulation of direct interspecies electron transfer (DIET), while the need for their constant dosing due to poor separation from effluent impairs economic feasibility. This study used an approach of spatially separating magnetite and granular activated carbon (GAC) from the organic fraction of municipal solid waste (OFMSW) in a single reactor for THSAD.

Sexual well-being among partnered adults and couples over 60: a scoping review.

Introduction: Although society still holds age-related stereotypes dismissing the sexuality of aging individuals, older adults remain sexually active and find sexuality to be an important part of their quality of life. Primarily oriented toward a biomedical and dysfunctional lens, prior research neglected the subjective well-being of elderly individuals, especially partnered adults and couples aged 60 years or more. Shedding a more positive light on this area of life could promote older individuals' and couples' sexual well-being.
