Objective: We describe the etiology of clinical forms of depression and their interaction with workplace factors.
Methods: We performed selective literature searches in pertinent research areas and reviewed the literature in the context of clinical experience in several depression programs at Johns Hopkins.
Results: Substantial research exists about the causes of depression. The causes of clinical forms of depression are complex. Genetic factors, several specific brain disorders, gender, as well as life events or circumstances all are involved in the causal pathway. Research addressing how the work environment impacts depression and its role in aggravating or alleviating depression is more limited.
Conclusions: Research findings about the various causal connections in depressive disorders may provide some guides to treatment as well as to further research on depression in the workplace.

The content of 39 metals and metalloids (MMs) in submicron road dust (PM fraction) was studied in the traffic zone, residential courtyards with parking lots, and on pedestrian roads in parks in Moscow. The geochemical profiles of PM vary slightly between different types of roads and courtyards but differ significantly from those in parks. In Moscow, compared to other cities worldwide, submicron road dust contains less As, Sb, Mo, Cr, Cd, Sn, Tl, Ca, Rb, La, Y, U, but more Cu, Zn, Co, Fe, Mn, Ti, Zr, Al, V.

How do people model the world's dynamics to guide mental simulation and evaluate choices? One prominent approach, the Successor Representation (SR), takes advantage of temporal abstraction of future states: by aggregating trajectory predictions over multiple timesteps, the brain can avoid the costs of iterative, multi-step mental simulation. Human behavior broadly shows signatures of such temporal abstraction, but finer-grained characterization of individuals' strategies and their dynamic adjustment remains an open question. We developed a task to measure SR usage during dynamic, trial-by-trial learning.

Large-scale and detailed analyses of activity in the United States (US) remain limited. In this work, we leveraged the comprehensive wearable, demographic, and survey data from the All of Us Research Program, the largest and most diverse population health study in the US to date, to apply and extend the previous global findings on activity inequality within the context of the US. We found that daily steps differed by sex at birth, age, body characteristics, geography, and built environment.

The "La Esperanza" native mercury mine in Aranzazu, (Caldas, Colombia) was active from 1948 until 1975. Before the final closure of the mine, the company began using dimercaprol (BAL, British Anti-Lewisite) and penicillamine for the treatment of hydrargyrism among workers. Mercury poisoning among miners was frequent due to precarious working conditions, inadequate technology, difficult terrain, and the high toxicity of native mercury within the mine.

Selenium promotes plant growth and improves nutritional quality, and the role of nano-selenium in alfalfa in regulating nutritional quality is unknown. In this study, using the N labeling method, it was found that nano-selenium could promote plant nitrogen metabolism and photosynthesis by increasing the light energy capture capacity and the activities of key enzymes of the nitrogen metabolism process, leading to an increase in alfalfa nitrogen accumulation and dry matter content. The transcriptome and metabolome revealed that nano-selenium mainly affected the pathways of 'biosynthesis of amino acids', 'starch and sucrose metabolism', 'pentose and glucuronate interconversions', 'pentose phosphate pathway', and 'flavonoid biosynthesis'.
