The amino acids arginine and ornithine are the precursors of a wide range of nitrogenous compounds in all living organisms. The metabolic conversion of ornithine into arginine is catalyzed by the sequential activities of the enzymes ornithine transcarbamylase (OTC), argininosuccinate synthetase

Vegetative propagation through somatic embryogenesis is critical in conifer biotechnology towards multivarietal forestry that uses elite varieties to cope with environmental and socio-economic issues. An important and still sub-optimal process during in vitro maturation of somatic embryos (SE) is

Low molecular weight globulins, which are abundant proteins in the Pinus pinaster Ait. megagametophyte, were purified and characterized. They showed a dimeric structure formed of one large and one small subunit linked by disulfide bridges. They were characterized by a high Arg and Glx content and by

We evaluated the effectiveness of antioxidant co-supplementation therapy using Larginine and Pycnogenol(®) in Japanese men with oligoasthenozoospermia and mild erectile dysfunction (ED). A total of forty-seven adult males with oligoasthenoteratozoospermia syndrome (OAT) were eligible for enrollment.

Nitrate and ammonium are the main forms of inorganic nitrogen available to plants. The present study aimed to investigate the metabolic changes caused by ammonium and nitrate nutrition in maritime pine (Pinus pinaster Ait.). Seedlings were grown with five solutions containing different

Pycnogenol, an extract of bark from the French maritime pine, Pinus pinaster Ait., consists of a concentrate of water-soluble polyphenols. Pycnogenol contains the bioflavonoids catechin and taxifolin as well as phenolcarbonic acids. Antioxidants, such as bioflavonoids, enhance endothelial nitric

High levels of nitrogen are stored as arginine during the last stages of seed formation in maritime pine (Pinus pinaster Aiton). The protein sensor PII regulates the feedback inhibition of arginine biosynthesis through interaction with the key enzyme N-acetylglutamate kinase (NAGK). In

OBJECTIVE Lower urinary tract symptoms (LUTS) and sexual dysfunction (SDys) are common problems that affect quality of life (QOL) in elderly men. In addition to prescribed drugs, many over-the-counter medications including supplements are used to treat QOL diseases. Phosphodiesterase inhibitors are

OBJECTIVE French maritime pine bark extract (Flavangenol) has been known to produce an endothelium-dependent vasodilatory effect. In the present study, we evaluated whether a dietary supplementation of Flavangenol exhibits antihypertensive action using deoxycorticosterone acetate (DOCA)-salt

OBJECTIVE The aim of this study was to investigate the influence of Prelox®R, a combination of French maritime pine bark extract (Pycnogenol®), L-arginine, L-citrulline and roburins, on male fertility. METHODS Sperm quality of 50 subfertile men was tested in monthly intervals in a double-blind,

Extension of the healthy life span is of primary importance for the aging society. Among exercise, healthy nutrition, and mental training, food supplements are widely used as preventive measures to postpone the diverse symptoms of aging. The extract from the bark of the French maritime pine,

OBJECTIVE Primary objective of the study was the evaluation of effects of a combination of plant extracts and aminoacids on erectile function (ED). METHODS The study was performed as a randomized, placebo-controlled, double-blind, cross-over study. 50 men with moderate ED received a combination of
