Higher alcohols that contain more than two carbon atoms have better fuel properties than ethanol, making them important supplements and alternatives to fossil fuels. Using microbes to produce higher alcohols from renewable biomass can alleviate the current energy and environmental crises, and has become a major future direction for green biomanufacturing. Since natural microbes can only produce a few higher alcohols in small amounts, it is necessary to reconstruct the synthetic pathways for higher alcohols in model industrial strains through metabolic engineering and synthetic biology to overcome the metabolic bottlenecks. A series of milestones have been accomplished in past decades. The authors of this review have witnessed the entire journey of this field from its first success to the leaping development. On the 30th anniversary of the founding of the discipline of metabolic engineering, this review dates back to the great milestones in achieving heterologous production of higher alcohols in non-native strains. The design and optimization of high alcohol biosynthetic pathways, the expansion of feedstock, the engineering of host strains and the industrialization process are summarized. This review aims to draw further attention to microbial synthesis of higher alcohols, inspire the development of novel techniques and strategies of metabolic engineering, and promote the innovation and upgrade of China's biofuel industry.

Among military service members, the experience of never-deploying can create a negative affective state (i.e., "non-deployment emotions"; (NDE)) that increases stress and may contribute to higher rates of substance use among Reserve and National Guard soldiers.

Purpose: To explore the potential correlation between subjective and measured visual function, as well as to analyse the influence of eye disease, socioeconomic factors and emotional dimensions.
Methods: Semi-structured interviews, physical examinations and functional tests (n = 1203). Demographics covered sex, marital status, education, household economy, smoking and alcohol.

Background: There is a gap in the extant literature regarding length of stay (LOS) in short-term inpatient addiction treatment facilities. Furthermore, there is a lack in focus on treatment factors which may be better indicators for positive patient outcomes than demographic profiles. The current study sought to examine modifiable correlates of LOS within a short-term inpatient residential facility to extend LOS and improve patient outcomes.

RNA viruses have high genetic diversity, allowing rapid adaptation to environmental pressures, such as disinfection. This diversity increases the likelihood of mutations influencing the viral sensitivity to disinfectants. Ethanol is widely used to control viral transmission; however, insufficient disinfection facilitates the survival of less-sensitive viruses.

Quinoa, rich in pharmacologically active ingredients, possesses the potential benefit in preventing cognitive impairments induced by hypoxia. In this study, the efficacy of quinoa ethanol extracts (QEE) consumption (200 and 500 mg/kg/d, respectively) against hypobaric hypoxia (HH)-induced cognitive deficits in mice was investigated. QEE significantly ameliorated hypoxic stress induced by HH, as evidenced by improvements in baseline indices and reductions in hypoxia-inducible factor 1α levels.
