Evaluation of efficacy of Silybum marianum flower extract on the mitigating hair loss in vitro and in vivo.

Background: Natural components that can exert a wide range of anti-hair loss activity with fewer side effects are in high demand. The objective of this study was to investigate the anti-hair loss potential of Silybum marianum flower extract (SMFE) in vitro and in vivo.

Methods: The effect of SMFE on dermal papilla cells was evaluated by measuring cell proliferation and VEGF production in hair follicle dermal papilla cells (HFDPCs).

3D printing technology to control BMP-2 and VEGF delivery spatially and temporally to promote large-volume bone regeneration.

When large engineered tissue structures are used to achieve tissue regeneration, formation of vasculature is an essential process. We report a technique that combines 3D printing with spatial and temporal control of dual growth factors to prevascularize bone tissue. Human dental pulp stem cells (DPSCs) that have both osteogenic and vasculogenic potential were printed with bone morphogenetic protein-2 (BMP-2) in the peripheral zone of the 3D printed construct, and with the vascular endothelial growth factor (VEGF) in the central zone, in which a hypoxic area forms.

Hypoglycemic dipeptide cyclo (His-Pro) significantly altered plasma proteome in streptozocin-induced diabetic rats and genetically-diabetic (ob/ob) mice.

The proteins in plasma perform many important functions in the body, and the protein profiles of the plasma vary under different physiological and pathological conditions. In an attempt to identify novel marker proteins for diabetes prognosis, we examined the effect of hypoglycemic dipeptide cyclo (His-Pro) (CHP) on the differential regulation of plasma proteins in streptozocin-induced diabetic rats and genetically-diabetic (ob/ob) mice. The orally-administrated CHP produced an excellent hypoglycemic effect in both animal models, lowering the average plasma glucose level by over 50 %.

Differential gene expression in pancreatic tissues of streptozocin-induced diabetic rats and genetically-diabetic mice in response to hypoglycemic dipeptide cyclo (His-Pro) treatment.

Diabetic studies are mostly interested in gene expression in the pancreas, the site of insulin secretion that regulates blood glucose levels. However, a single gene approach has been ruled out for many years in discovering new genes or the molecular networks involved in the induction process of diabetes. To understand the molecular mechanisms by which cyclo (His-Pro) (CHP) affects amelioration of diabetes mellitus, we performed gene expression profiling in the pancreatic tissues of two diabetic animal models, streptozocin (STZ)-induced diabetic rats (T1DM) and genetically-diabetic (C57BL/6J ob/ob) mice (T2DM).

Alterations in pancreatic protein expression in STZ-induced diabetic rats and genetically diabetic mice in response to treatment with hypoglycemic dipeptide Cyclo (His-Pro).

To provide insights into the molecular mechanisms underlying diabetes mellitus, we performed a proteomic study on two diabetic animal models, streptozotocin (STZ)-induced diabetic rats (T1DM) and genetically diabetic (C57BL/6J ob/ob) mice (T2DM). To better understand the recovery process of those diabetic rodents, we examined the effect of hypoglycemic dipeptide Cyclo (His-Pro) (CHP) treatment on the differential expression of pancreatic proteins in both animal models. Oral administration of CHP had an excellent hypoglycemic effect in both animal models, lowering the average plasma glucose level by over 50%.
