We present results of searches for technirho (rho(T)), techniomega (omega(T)), and Z' particles, using the decay channels rho(T),omega(T),Z'-->e(+)e(-). The search is based on 124.8 pb(-1) of data collected by the D0 detector at the Fermilab Tevatron during 1992-1996. In the absence of a signal, we set 95% C.L. upper limits on the cross sections for the processes pp-->rho(T),omega(T),Z'-->e(+)e(-) as a function of the mass of the decaying particle. For certain model parameters, we exclude the existence of degenerate rho(T) and omega(T) states with masses below about 200 GeV. We exclude a Z' with mass below 670 GeV, assuming that it has the same couplings to fermions as the Z boson.

Objectives: Increasing research has shown that heavy metal as a neurotoxicant affects cognitive function across the lifespan. Nutritional status may modify susceptibility to heavy metal exposures, which further impacts cognition.
Methods: We conducted a comprehensive search for cross-sectional studies, longitudinal studies, case-control studies and clinical trials on the interaction between nutrient and heavy metal, as well as mixed heavy metal exposure, in relation to cognition across the lifespan.

Background: With increasing age, dementia is a common disease in the elderly population,especially Alzheimer's disease. Owing to the nature of the disease, the function of patients deteriorates, which places a heavy burden on the country and family. Home-based training programs have been shown to improve cognitive function in patients with dementia.

The black garden ant () is a widely distributed species across Europe, North America, and North Africa, playing a pivotal role in ecological processes within its diverse habitats. However, the microbiome associated with remains poorly investigated. In the present study, we isolated a novel species, , from the soil of the anthill.

Background: Gamma-hydroxybutyrate (GHB) and its precursors gamma-butyrolactone (GBL) and 1,4-butanediol (BD) have become a significant concern due to the increase in their recreational use and the high risks associated with it (e.g., overdose, addiction, life-threatening withdrawal syndromes).

Background: Like other countries developing standardized general practice training, China faces the challenge of training vast numbers of new general practice faculty. However, little is known about these clinician-teachers' motivations and perceived needs for faculty development. This review intended to explore available published data on Chinese general practice faculty development needs and motivation for ongoing professional development.
