Impact of light spectrum electromagnetic radiation variations on performance and hormonal profiles in laying hens.

Avian photopic curves show energy peaks at different wavelengths than humans, particularly in the ultraviolet, yellow, and red range. Therefore, an illumination system with a spectrum tailored for laying hens, encompassing the entire visible spectrum, can enhance performance and welfare. The primary contribution of this study was the development of two Spectral Power Distributions (SPDs) specifically designed for laying hens, with different spectral proportions (S1 and S2), and the evaluation of their effects on productive performance, egg quality, and hormonal levels, compared to conventional white lighting at 3000 K (C).

Analgesic and Anti-Arthritic Potential of Methanolic Extract and Palmatine Obtained from Leaves.

: is used in folk medicine to treat pain and arthritis. Palmatine is an alkaloid isolated from several plants, including leaves. The aim of the present study was to investigate the analgesic, anti-arthritic, and anti-inflammatory potential of the methanolic extract of (EMAS) and palmatine.

Absence of maternal-fetal adverse effects of . Beauv. following treatment during pregnancy in mice.

P. Beauv is a plant native to Brazil that exhibits various beneficial activities including antioxidant, antibacterial, antifungal, antiprotozoal, anti-hyperalgesic, and anti-inflammatory properties. The aim of this study was to assess the impact of the ethanol extract of (EEAl) on reproductive outcomes, embryofetal development, and DNA integrity of pregnant female mice.

Biochemical Parameters of Female Wistar Rats and Their Offspring Exposed to Inorganic Mercury in Drinking Water during the Gestational and Lactational Periods.

The aim of this study was to investigate the effects of inorganic mercury (Hg) exposure on biochemical parameters of dams and their offspring exposed to metal in drinking water. Female Wistar rats were exposed to 0, 10, and 50 µg Hg/mL (as HgCl) for 42 days corresponding to gestational (21 days) and lactational (21 days) periods. The offspring were sacrificed on postnatal days 10, 20, 30, and 40.

Anti-inflammatory Properties of Ethanolic Extract and 2″-O-β-D-Glucopyranosyl-vitexin Obtained from Alternanthera tenella Colla Whole Plant.

Six flavonoids were identified and isolated from the ethanolic extract of Alternanthera tenella Colla (Amaranthaceae) whole plant (EEAT) including 2″-O-β-D-glucopyranosyl-vitexin (A19). Flavonoids have anti-inflammatory activity; however, the 2″-O-β-D-glucopyranosyl-vitexin anti-inflammatory property was not totally explored. The aim of the present study was to investigate the anti-inflammatory effects of ethanolic extract from A.

Mercury toxicity in pregnant and lactating rats: zinc and N-acetylcysteine as alternative of prevention.

This study evaluated the toxic effects of inorganic mercury (Hg) in pregnant and lactating rats, as well as the possible protective effect of zinc (Zn) and N-acetylcysteine (NAC). Pregnant and lactating rats were pre-treated with ZnCl (27 mg/kg) and/or NAC (5 mg/kg) and after 24 h, they were exposed to HgCl (10 mg/kg). Animals were sacrificed 24 h after Hg exposure, and biochemical tests and metal determination were performed.

Effects of Zinc and N-Acetylcysteine in Damage Caused by Lead Exposure in Young Rats.

This study investigated the toxicity of rats exposed to lead acetate (AcPb) during the second phase of brain development (8-12 days postnatal) in hematological and cerebral parameters. Moreover, the preventive effect of zinc chloride (ZnCl) and N-acetylcysteine (NAC) was investigated. Pups were injected subcutaneously with saline (0.

Inorganic mercury exposure in drinking water alters essential metal homeostasis in pregnant rats without altering rat pup behavior.

The aim of this work was to investigate the effects of HgCl exposure in the doses of 0, 10 and 50μg Hg/mL in drinking water during pregnancy on tissue essential metal homeostasis, as well as the effects of HgCl exposure in utero and breast milk on behavioral tasks. Pregnant rats exposed to both inorganic mercury doses presented high renal Hg content and an increase in renal Cu and hepatic Zn levels. Mercury exposure increased fecal Hg and essential metal contents.

Effects of zinc against mercury toxicity in female rats 12 and 48 hours after HgCl2 exposure.

This work investigated the toxicity of inorganic mercury and zinc preventive effects in female rats sacrificed 12 or 48 h after HgCl2 exposure. Female Wistar rats were subcutaneously injected with ZnCl2 (27 mg/kg) or saline (0.9 %), and 24 h later they were exposed to HgCl2 (5 mg/kg) or saline (0.

Zinc and N-acetylcysteine modify mercury distribution and promote increase in hepatic metallothionein levels.

This study investigated the ability of zinc (Zn) and N-acetylcysteine (NAC) in preventing the biochemical alterations caused by mercury (Hg) and the retention of this metal in different organs. Adult female rats received ZnCl2 (27mg/kg) and/or NAC (5mg/kg) or saline (0.9%) subcutaneously and after 24h they received HgCl2 (5mg/kg) or saline (0.
