Introduction: The female athlete triad (FAT) is a serious health-related problem that threatens women who exercise. This condition is an interrelated multifactorial syndrome which includes low energy availability, menstrual cycle disturbances and decreased bone mineral density.
Objective: To review the major components of the FAT and their relationships, as well as strategies for diagnosis and treatment.
Methods: Articles related to the topic were reviewed through PubMed and SportDiscus databases.
Results: Interrelationship between components of the FAT may result in clinical manifestations, including eating disorders, amenorrhea and osteoporosis. Clinical conditions are not always exhibited simultaneously. Prevention is important to minimize complications. Diagnosis and treatment is complicated and often must involve an interdisciplinary therapeutic approach.
Conclusions: Understanding of the disease may be facilitated by a unified framework focusing on energy deficiency. Preventive or early interventions require to increase energy availability through a higher total energy intake or a decrease in energy expenditure trough excessive physical exercise. A healthy lifestyle, and support by parents and coaches should be included. Psychotherapy may be necessary when eating disorders are present.

Microbial activity in the deep continental subsurface is difficult to measure due to low cell densities, low energy fluxes, cryptic elemental cycles and enigmatic metabolisms. Nonetheless, direct access to rare sample sites and sensitive laboratory measurements can be used to better understand the variables that govern microbial life underground. In this study, we sampled fluids from six boreholes at depths ranging from 244 m to 1,478 m below ground at the Sanford Underground Research Facility (SURF), a former goldmine in South Dakota, United States.

The oxidation of Met residues in proteins is a complex process, where protein-specific structural and dynamical features play a relevant role in determining the reaction kinetics. Aiming to a full-side perspective, we report here a comprehensive characterization of Met oxidation kinetics by hydrogen peroxide in a leptin protein case study. To do that, we estimated the reaction-free energy profile of the Met oxidation via a QM/MM approach, while the kinetics of the formation of the reactive species were calculated using classical molecular dynamics (MD) simulations.

Fabrication of heavy density mortar using aggregates reinforced with available solid inorganic chemical additives is of a great importance as a protective layer to mitigate radiations in nuclear facilities. The effect of lead oxide and borax decahydrate on the hydration kinetics was evaluated by determining setting time, leachability and compressive strength. To speed up the reaction, 0.

Electrocatalytic nitrate reduction reaction (NORR) to harmless nitrogen (N) presents a viable approach for purifying NO-contaminated wastewater, yet most current electrocatalysts predominantly produce ammonium/ammonia (NH/NH) due to challenges in facilitating N-N coupling. This study focuses on identifying metal catalysts that preferentially generate N and elucidating the mechanistic origins of their high selectivity. Our evaluation of 16 commercially available metals reveals that only Pb, Sn, and In demonstrated substantial N selectivity (79.

Micronization is frequently employed to increase the dissolution of poorly soluble drugs, but it easily led to powder aggregation and difficult to mix well on the micro level with poor content uniformity and erratic dissolution behavior. Mannitol is the most commonly used pharmaceutical excipient, and its β form (β-mannitol) is commercially available and extensively investigated, whereas form α (α-mannitol) remain poorly understood. Here, this study demonstrated that α-mannitol could significantly eliminate aggregation phenomena of micronized drugs (i.
