Objective: To study the effects of behind legs vibrations on erectile function in male rabbits through the concentration of plasma reproductive hormone and the expression of nitric oxide synthase (eNOS), endothelin-1 (ET-1) mRNA in vibrated male rabbits.
Methods: 30 male adult rabbits were assigned randomly to A group (vibration power: 3.02 m/s(2)), B group (vibration power: 6.13 m/s(2)), C group (vibration power: 12.26 m/s(2)) and control group. The concentration of expression of eNOS, ET-1 mRNA were measured with RT-PCR after rated for 30 days.
Results: (1) Compared with 0 days vibration, after exposure to vibration for 10, 20, 30 days, the A, B, C group concentration of plasma T, LH are much lower (P < 0.05), the concentration of plasma E2 is much higher. (2) Compared with control group after exposed for 30 days, the expression of ET-1 mRNA [B group:(17.39 +/- 4.59) x 104; C group: (36.21 +/- 13.13) x 104 ] were much higher and expression of eNOS mRNA [A group: (19.11 +/- 6.83) x 104; B group: (11.86 +/- 3.15) x 104; C group: (4.68 +/- 3.26) x 104] was much lower, there were significant differences (P < 0.01).
Conclusions: The vibration of behind legs in rabbits resulted the concentration of plasma T, LH are much lower, the concentration of plasma E2 is much higher, increased the expression of eNOS mRNA, decreased the expression of eNOS mRNA, then vary the erectile function.

Introduction: Heavy metal pollution threatens the biodiversity and ecological equilibrium of the Nile River. This study investigates the impact of heavy metal pollution on aquatic animals such as Nile tilapia (Oreochromis niloticus) in the Damietta branch of the River Nile and El-Rayah El-Tawfeeky canal in Benha City in Egypt.
Methods: Fish and water samples were collected from the Damietta branch and El-Rayah El-Tawfeeky during the fall of 2022.

The ruthenium compounds have been known to have the wide range of potential applications as anticancer, antibacterial and anti-diabetic etc. The ligand substitutions play a vital role in enhancing the pharmacological and biological activities. In the present study, three ruthenium-metal based complexes, designated as (I-III), were synthesized and characterized employing element analysis, FTIR and HNMR.

A highly sensitive and rapid LC-MS/MS method was developed and validated for the quantification of dexamethasone in rat plasma and brain tissue. Protein precipitation method was used for sample preparation. The separation of dexamethasone and the IS (labetalol) was achieved on an Atlantis dC column using an isocratic mobile phase (10 mM ammonium formate and acetonitrile, 25/75, v/v) delivered at 0.

Introduction: Neuropsychiatric symptoms (NPSs) are common in dementia with Lewy bodies (DLB) but their neurobiological mechanisms are poorly understood.
Methods: NPSs and cognition were assessed annually in participants (DLB n = 222; Alzheimer's disease [AD] n = 125) from the European DLB (E-DLB) Consortium, and plasma phosphorylated tau-181 (p-tau181) and p-tau231 concentrations were measured at baseline.
Results: Hallucinations, delusions, and depression were more common in DLB than in AD and, in a subgroup with longitudinal follow-up, persistent hallucinations and NPSs were associated with lower p-tau181 and p-tau231 in DLB.

Metabolomics can describe the molecular phenome and may contribute to dissecting the biological processes linked to economically relevant traits in livestock species. Comparative analyses of metabolomic profiles in purebred pigs can provide insights into the basic biological mechanisms that may explain differences in production performances. Following this concept, this study was designed to compare, on a large scale, the plasma metabolomic profiles of two Italian heavy pig breeds (Italian Duroc and Italian Large White) to indirectly evaluate the impact of their different genetic backgrounds on the breed metabolomes.
