4D Mapping of ZIF Biocomposites for High Protein Loading and Tunable Release Profiles

Advanced Functional Materials, EarlyView.
Systematic four‐dimensional mapping of zeolitic imidazolate framework biocomposites reveals how precursor ratios, total concentration, and washing define crystalline phase, protein loading, and release kinetics. This comprehensive study identifies conditions yielding record loading (∼85%) and precise phase–property correlations.

Seasonal Patterns in Growth Hormone, Insulin and Insulin-like Growth Factor-1 in Female Muskoxen

Rangifer, 1997
Over a year, mean serum growth hormone concentrations ranged from 0.5 to 3 ng/ml in tame muskoxen with the lowest values and fewest pulses between October and January. Serum insulin ranged from 0.25 to 0.92 ng/ml, with minima in summer. There were marked

Insulin‐like growth factor‐1 and site‐specific cancers: A Mendelian randomization study

Cancer Medicine, 2020
Insulin‐like growth factor‐1 (IGF‐1) is involved in several processes relevant to carcinogenesis. We used 416 single‐nucleotide polymorphisms robustly associated with serum IGF‐1 levels to assess the potential causal associations between this hormone and

Oral Dosed Organo‐Silica Nanoparticles Restore Glucose Homeostasis and β‐Cell Function in Diabetes Rats

Advanced Functional Materials, EarlyView.
An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...

Effects of intermittent fasting during ramadan on insulin-like growth factor-1, interleukin 2, and lipid profile in healthy muslims

International Journal of Preventive Medicine, 2019
Background: Insulin-like growth factor-1 (IGF-1) and interleukin-2 (IL-2) play an essential role in pathophysiology of several chronic diseases. As a stressor, fasting in Ramadan may increase inflammatory markers such as IGF-1 and IL-2 in Muslims.

A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds

Advanced Healthcare Materials, EarlyView.
Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...

The use of insulin-like growth factor 1 improved the parameters of the seminogram in a patient with severe oligoasthenoteratozoospermia

SAGE Open Medical Case Reports, 2019
Male patients suffering from oligoasthenoteratozoospermia typically failed to achieve pregnancy, even with assisted reproductive technologies. Growth hormone and insulin-like growth factor 1 have been shown to regulate sperm quality parameters; therefore,

Short children born small for gestational age (SGA) : puberty, hormonal profiles, combined GnRHa and GH treatment and (epi)genetics of 2 IGFBP gene promotors [PDF]

, 2008
In the Netherlands, children who remain short after being born small for gestational age (SGA) are treated with growth hormone (GH). The clinical studies described in this thesis focused on treatment options in short children born SGA who came under ...

A Novel Microfluidic System for 3D Epidermis and Full‐Thickness Skin Growth for Nanoparticle Safety Assessment

Advanced Healthcare Materials, EarlyView.
This work presents a novel, dynamically perfused, configurable microfluidic system for epidermis‐only (E and full‐thickness skin (FT SoC) growth, emulating human skin structure and barrier function. Upon TiO2 nanoparticle exposure, the system reveals compromised barrier integrity, reduced metabolic activity, increased permeability, and chemokine‐driven

Insulin-like growth factor 1 and insulin-like growth factor binding protein-3 as predictive biomarkers of depression and migraine in obese women

The Egyptian Journal of Internal Medicine, 2019
Introduction Obesity and its comorbidity, depression and migraine, are highly prevalent conditions and public health problems of enormous scope that are responsible for the significant quality of life impairment and financial cost.
