INTRODUCTION In the search for biomarkers that allow the prediction of neonatal growth and development, placental growth hormone(PGH), pituitary growth hormone (GH1), insulin-like growth factor 1 (IGF-1), and ghrelin concentrations were assessed in the amniotic fluid and in the umbilical cord blood of 92 neonates. MATERIAL AND METHODS The proteins were assayed by the ELISA method. Their conce...

BACKGROUND IGF-I gene expression and IGF-I plasma concentration decline with age. A decreased sensitivity to GH has been suggested to be a contributory mechanism to this, in addition to attenuated GH secretion. OBJECTIVE This study focuses on the sensitivity to exogenous GH and the reversibility of the reduced IGF-I gene expression in aging male rats. DESIGN Three groups of male Wistar rats...

HANEW, K., SASAKI, A. and YOSHINAGA, K. Evidence for Endogenous Dopaminergic Control of OH Release in Man. Tohoku J. exp. Med., 1981, 135 (1), 103-108 In order to determine whether or not there is a tonic dopamine (DA) control of GH release, the effect of an anti-dopaminergic agent, sulpiride, on GH secretion was studied in 12 normal subjects. After the administration of sulpiride, serum concen...

Bacteriocin-like inhibitory substances (BLIS) produced by Lactococcus lactis Gh1 had shown antimicrobial activity against Listeria monocytogenes ATCC 15313. Brain Heart Infusion (BHI) broth is used for the cultivation and enumeration of lactic acid bacteria, but there a need to improve current medium composition enhancement BLIS production, one approaches model optimization process identify mos...

The exploration of natural antimicrobial compounds is necessary due to the current bacterial resistance synthetic antibiotics. For this reason, pineapple residues were evaluated as a source phenolic with capacity. Pineapple fermented A. niger GH1 and subjected ultrasound for extraction compounds. In solid-state fermentation (SSF), peel core (70:30) 32 h. Ultrasonic-assisted (UAE) was optimized....

The objective of this study was to determine the minimum dosage of recombinant bovine somatotropin (bST) required to elicit maximum depression in plasma urea nitrogen (PUN), an indicator of anabolic activity. Twenty-four steers (389 kg) were blocked by weight into six pens. Six steers were placed on each of the following bST doses: 0, 8, 16 and 32 mg bST/d. Treatments were administered once dai...

New ß-glucosidases with product (glucose) or ethanol tolerances are greatly desired to make industrial processes more marketable and efficient. Therefore, this report describes the in silico/vitro characterization of Bg10, a metagenomically derived homodimeric ß-glucosidase that exhibited a Vmax of 10.81 ± 0.43 μM min-1, Kcat of 175.1± 6.91 min-1, and Km of 0.49 ± 0.12 mM at a neutral pH and 37...
