Article Abstract
Background: Adiponectin is considered an important factor in the pathogenesis of cardiovascular and metabolic diseases, due to its anti- atherogenic and anti-inflammatory properties. Few studies, however, have suggested the existence of a direct association between adiponectin levels and cardiorespiratory fitness and physical activity levels.
Objective: To verify the influence of the nutritional status and cardiorespiratory fitness on plasma adiponectin levels in adult men.
Methods: A total of 250 subjects, all in active duty in the Brazilian Army (BA), with a mean age of 42,6 ± 4,8 years volunteered to participate in the study. Plasma levels of adiponectin were measured, as well as body mass, height, waist circumference (WC), fat percentage by hydrostatic weighing and VO(2max) by ergospirometry. A questionnaire was used to obtain the characteristics of the physical training performed by the individuals.
Results: The sample showed that 121 (48%) individuals were overweight and 36 (14%) were obese. Moreover, 66 individuals (27%) had a body fat percentage > 25% and 26,7% had a WC > 94 cm. Overweight and obese individuals had significantly lower adiponectin levels than those with an adequate nutritional status. Individuals at the highest tertile of VO(2max) had higher adiponectin levels than the others. The adiponectin levels were positively correlated with the total weekly physical training time and VO(2max) and inversely correlated with body mass, BMI and WC. The correlation between adiponectin levels and VO(2max) did not remain significant after being adjusted for BMI and WC.
Conclusion: Individuals with better cardiorespiratory fitness and normal nutritional status seem to present healthier levels of adiponectin.

Impact of protein intake from a caloric-restricted diet on liver lipid metabolism in overweight and obese rats of different sexes.

In addition to being linked to an excess of lipid accumulation in the liver, being overweight or obese can also result in disorders of lipid metabolism. There is limited understanding regarding whether different levels of protein intake within an energy-restricted diet affect liver lipid metabolism in overweight and obese rats and whether these effects differ by gender, despite the fact that both high protein intake and calorie restriction can improve intrahepatic lipid. The purpose of this study is to explore the effects and mechanisms of different protein intakes within a calorie-restricted diet on liver lipid metabolism, and to investigate whether these effects exhibit gender differences.

Circadian rhythms of metabolic, hormonal, and behavioral fluctuations and their alterations can impact health. An important gap in knowledge in the field is whether the time of the day of exercise and the age of onset of exercise exert distinct effects at the level of whole-body adipose tissue and body composition. The goal of the present study was to determine how exercise at different times of the day during adolescence impacts the adipose tissue transcriptome and content in a rodent model.

The dipeptide Tyr-Pro, a novel natural agonist of adiponectin receptor 1 (AdipoR1), promotes glucose uptake in skeletal muscle cells. This study investigated the antidiabetic effect of orally administered Tyr-Pro in spontaneously diabetic Torii (SDT) rats. Oral administration of Tyr-Pro (1 mg/kg/day) improved glucose intolerance in SDT rats at 22 weeks of prediabetic age.

Background & Aims: Lanifibranor is a pan-PPAR agonist that improves glucose/lipid metabolism and reverses steatohepatitis and fibrosis in adults with MASH. We tested its effect on insulin resistance at the level of different target tissues in relationship to change in intrahepatic triglyceride (IHTG) content.
Methods: This phase 2, single center, study randomized (1:1) 38 patients with T2D and MASLD to receive lanifibranor 800 mg or placebo for 24 weeks.
Adipose tissue may not be a major player in the inflammatory pathogenesis of Autism Spectrum Disorder.

Institute of Maternal and Child Medicine, Shenzhen Maternity and Child Healthcare Hospital, Southern Medical University, Shenzhen, China.
Purpose: Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder increasingly recognized for its strong association with chronic inflammation. Adipose tissue functions as an endocrine organ and can secrete inflammatory cytokines to mediate inflammation. However, its involvement in ASD-related inflammation remains unclear.
