You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Chemical"].

Please return the output as a JSON object of the format: {"Chemical": ["Arsenic", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Anti-inflammatory effects of a special carbohydrate-whey protein cake after exhaustive cycling in humans. Intense exercise induces increased levels of pro-inflammatory and anti-inflammatory cytokines. Thus, the purpose of this study was to examine the effects of a special cake (consisting of carbohydrate to whey protein 3.5:1) vs. an isocaloric carbohydrate cake on inflammatory markers after exhaustive cycling in humans. Nine subjects received either the experimental or placebo cake in a counterbalanced fashion using a crossover, double-blind, repeated-measures design. They performed one trial involving a 2h exercise on a cycle ergometer at 60-65% VO2max followed by a 4h recovery and then a second trial involving an 1h exercise at 60-65% VO2max which was increased at 95% VO2max. Blood samples were collected pre-exercise, 30min and 4h post-exercise, post-time Trial and 48h post-time Trial. Cakes were consumed immediately post-exercise and every 1h for the next 3h. The results showed that consumption of the experimental cake reduced significantly (p<0.05), 4h post-exercise, the pro-inflammatory protein levels IL-6 and CRP compared to the control group by 50% and 46% respectively. Moreover, in the experimental cake group, the level of the anti-inflammatory cytokine IL-10 was higher by 118%, 4h post-exercise, compared to the control group but not statistically significant.
