An overview of symbiotic and pathogenic interactions at the fungi-plant interface under environmental constraints.

The complex and dynamic interactions between fungi and plants constitute a critical arena in ecological science. In this comprehensive review paper, we explore the multifaceted relationships at the fungi-plant interface, encompassing both mutualistic and antagonistic interactions, and the environmental factors influencing these associations. Mutualistic associations, notably mycorrhizal relationships, play a pivotal role in enhancing plant health and ecological balance.

Should women with high body mass index be denied fertility treatments?

Obesity is an emerging global epidemic with a negative impact on fertility. Almost all guidelines and policies have a stringent limit of body mass index (BMI) to access fertility services which has promoted a debate amongst fertility practitioners globally. Proponents of placing such a limit point to the negative impact of elevated BMI on the outcome of fertility treatment, its cost effectiveness and the risk it poses to the intending mother and unborn child.

The present study investigated the effects of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and combined maneb and paraquat on the mitochondrial proteome of the nigrostriatal tissues in the presence or absence of minocycline, levodopa and manganese (III) tetrakis (1-methyl-4-pyridyl) porphyrin (MnTMPyP).

Rodent models and contemporary molecular techniques: notable feats yet incomplete explanations of Parkinson's disease pathogenesis.

Rodent models and molecular tools, mainly omics and RNA interference, have been rigorously used to decode the intangible etiology and pathogenesis of Parkinson's disease (PD). Although convention of contemporary molecular techniques and multiple rodent models paved imperative leads in deciphering the role of putative causative factors and sequential events leading to PD, complete and clear-cut mechanisms of pathogenesis are still hard to pin down. The current article reviews the implications and pros and cons of rodent models and molecular tools in understanding the molecular and cellular bases of PD pathogenesis based on the existing literature.

Involvement of NADPH oxidase and glutathione in zinc-induced dopaminergic neurodegeneration in rats: similarity with paraquat neurotoxicity.

An association between excessive zinc (Zn) accumulation in brain and incidences of Parkinson's disease (PD) has been shown in several epidemiological and experimental investigations. The involvement of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and glutathione (GSH) in the pathogenesis of PD has also been proposed in a few studies. Despite the implicated role of oxidative stress in PD, the entire mechanism of Zn-induced dopaminergic neurodegeneration has not yet been clearly understood.

Role of secondary mediators in caffeine-mediated neuroprotection in maneb- and paraquat-induced Parkinson's disease phenotype in the mouse.

Maneb and paraquat are known to induce Parkinson's disease (PD) phenotype, however, caffeine offers neuroprotection. Nitric oxide (NO) acts an important mediator in PD phenotype and tyrosine kinase (TK), nuclear factor kappa B (NF-kB), p38 mitogen activated protein kinase (p38 MAPK) are known to regulate its production. The present study aimed to elucidate the role of caffeine in the regulation of NO production and microglial activation and their subsequent contribution in dopaminergic neuroprotection.
