Epidermal growth factor (EGF), a potent mitogen present in milk, is postulated to play an important physiologic role in the ontogeny of the intestine. An artificial rat milk, free of EGF, was developed and fed to newborn rats in an effort to evaluate the physiologic role of EGF on intestinal glucose transport. Comparisons were made between mother-fed (group 1) and artificially fed pups (group 2). Group 1 was divided into two subgroups to received either the EGF vehicle (group 1-A) or twice daily subcutaneous injections (0.1 micrograms/g body weight/day) of EGF (group 1-B). Group 2 was divided into four subgroups: formula without EGF (group 2-A), formula with 62 ng/ml of EGF (group 2-B), formula with 200 ng/ml EGF (group 2-C), and formula without EGF but added anti-EGF IgG (40 ng/ml) plus subcutaneous injections of 1 micrograms anti-EGF twice daily (group 2-D). Treatment regimens were initiated on day 3 and assays performed on day 11 of life. Glucose transport was measured using gut "sheet" preparations in all but group 2-C, which utilized brush border membrane preparations. Group 1-B showed a significant (p less than 0.03) increase in gut length (47.5 +/- 1.2 versus 42 +/- 0.9 cm) and an increase (p less than 0.03) in both Vmax (10.2 +/- 0.5 versus 7.2 +/- 0.3 nM/mg tissue) and Km (2.74 +/- 0.49 versus 1.20 +/- 0.19 mM) compared to group 1-A.(ABSTRACT TRUNCATED AT 250 WORDS)

The cysteine-rich epidermal growth factor ligand domain 2 protein (CRELD2) is associated with pathways that regulate epithelial-to-mesenchymal transition, a critical process driving cancer metastasis. This study aimed to determine the prognostic value of CRELD2 status on survival outcomes in triple-negative breast cancer (TNBC). Seventy patients were included in the study.

Purpose: Myopic choroidal neovascularization (CNV) is a common reason for visual impairment. This study investigated the clinical effects of repeated intravitreal injections of ranibizumab among patients with CNV secondary to pathologic myopia.
Methods: This study involved a single-center, non-randomized clinical prospective cohort research design including 39 patients with myopic CNV and a control group of 10 patients with cataract.

The ethanol-induced BALB/c mice and human gastric epithelial cell (Ges-1 cell) models were used to investigate the Sargassum siliquastrum fucoidan (SFuc) gastroprotective capability. The injury score and histopathological sections of the stomach were used to evaluate the gastroprotective capability. The western blotting and RT-PCR methods determined the signaling mechanism of mice's gastric injury.

Background: Epiphora and secondary ocular surface damage are increasingly impairing the quality of life of people, particularly elderly women. We aimed to investigate the changes in tear cytokine and lactoferrin levels in postmenopausal women with primary acquired nasolacrimal duct obstruction (PANDO) complicated with obstructed meibomian gland dysfunction (OMGD) and preliminary explore the pathological mechanisms of OMGD in patients with PANDO.
Methods: The prospective study involved 43 and 41 postmenopausal women with and without PANDO, respectively.
