Article Abstract
To identify distinct patterns of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein 3 (IGFBP-3) in girls with central precocious puberty (CPP), and to compare IGF-1 and IGFBP-3 levels in patients with CPP and precocious thelarche (PT). A literature search of PubMed, Embase, and Scopus databases was done to identify observational studies. Newcastle-Ottawa Scale (NOS) was used to assess the quality of the studies. Pooled weighted mean difference (WMD) and 95% confidence intervals (CI) were reported. Fourteen studies were included. As opposed to age-matched or similar-aged pre-pubertal girls, patients with CPP had significantly higher levels of IGF-1 and IGFBP-3. CPP was associated with higher levels of IGF-1 approaching statistical significance but similar levels of IGFBP-3 compared to PT. Distinct hormonal patterns, such as elevated IGF-1 and IGFBP-3, were identified in patients with CPP, suggesting a potential diagnostic value of IGF-1 and IGFBP-3 levels.

This study aimed to evaluate the effect of some environment- and animal-based factors, such as body condition score (BCS) on 15-20 days before parturition, parity, and calving season on colostrum dry matter (DM), fat, solids-nonfat (SNF), protein, and lactose contents as well as colostrum and calf's serum immunoglobulin (IgG, IgA, and IgM), IGF-1, and lactoferrin concentrations in buffaloes. Therefore, the components of colostrum (at the first milking) and calf serum samples (at 24-48 h and 28 days after birth) from 86 Anatolian buffalo cows were analyzed by an infrared milk analyzer and ELISA test. The high BCS enhanced colostrum DM, fat, and IgG content; calf serum IgG concentration at 24-48 h, and lactoferrin at 28 days compared to low BCS.

High- and low-protein diets have long been debated for their effects on body fat accumulation, which may stem from neglecting interactions with other macronutrients. This study investigates how the dietary carbohydrate-to-protein caloric ratio (CPCR) affects hepatic fat deposition via the IGF-1/PI3K/Akt signaling pathway. Within an isocaloric dietary framework, we evaluated the effects of varying CPCR (dietary fat held constant at 10 %) on hepatic fat accumulation in Sprague-Dawley rats over 8 weeks.
