Background/objectives: We evaluated the effects of a 12-week hypocaloric ketogenic diet (KD) on glucose and lipid metabolism, as well as body mass, in overweight, obese, and healthy-weight females. One hundred adult females completed the study, including 64 obese (97.99 ± 11.

Twenty male soccer players from the top league participated in the study. All subjects were evaluated for the serum concentration of 25(OH)D at the beginning of the preseason.

- * The study evaluated interaction energy through comparisons with spectroscopic data, geometric properties, and other factors to uncover correlations, particularly focusing on the C═O stretching frequency and nuclear magnetic resonance changes.
- * While the interaction energy can be estimated from experimental measurements, standard AIM measurements correlate less effectively, and the σ-hole depth on the Lewis acid does not strongly relate to bond strength due to the limitations of electrostatic metrics.
The interaction between two square palladium (II) dianions PdX (X=Cl, Br) is evaluated by crystal study and analyzed by quantum chemical means. The arrangement within the crystal between each pair of PdX neighbors is suggestive of a Pd⋅⋅⋅X noncovalent bond, which is verified by a battery of computational protocols. While the potential between these two bare dianions is computed to be highly repulsive, the introduction of even just two counterions makes this interaction attractive, as does the presence of a constellation of point charges.

This study assesses the risk of EDs among professional and amateur football players, considering these factors, and compares findings with a control group of non-athletes.
Methods: The study involved 170 participants, including non-athletes as a control group, categorized by sex and sport level.
