Manufactured nanoparticles have a wide range of application due to their advantageous properties whencompared with their bulk forms. There is a growing concern regarding the safety of nanoparticles. This studyaimed to evaluate the cell membrane lipoperoxidation (LPO) and DNA integrity in red earthworm Lumbricusrubellus when exposed to artificial soil systems containing different concentration o...

UNLABELLED Two different analytical methods were evaluated for their capacity to provide quantitative information on onion cell membrane permeability and integrity after high pressure and thermal processing and to study the impact of these processing treatments on cell compartmentalization and texture quality. To determine changes in cell membrane permeability and/or integrity the methodologies...

Medicinal plant possessed antifungal effects by many mechanisms, they caused membrane disturbance resulting in the loss of integrity, inhibited DNA transcription and reduced cell populations, activity fungal antioxidant enzymes biofilm formation. The current review discussed medicinal plants.

Aerobic conditions are required to maintain the viability of turkey sperm in vitro. In mammalian sperm, excess oxygen during in vitro storage results in lipid peroxidation, causing membrane damage and reduced sperm motility and subsequent fertility. The effect of adding antioxidants to turkey sperm during liquid storage was studied. Semen was collected and pooled from 20 toms and antioxidants w...

Numerous studies have demonstrated that cholesterol-rich membrane rafts play critical roles in multiple cellular functions. However, the impact of the lipoproteins on the structure, integrity and cholesterol composition of these domains is not well understood. This paper focuses on oxidized low-density lipoproteins (oxLDLs) that are strongly implicated in the development of the cardiovascular d...

The objective of this study was to assess the sperm membrane integrity in extended boar semen during storage time using specific spectrum laboratory methods. Boar semen was diluted with the long-term liquid commercial extenders Androhep (A), Androstar (AS), Androstar plus (AS+), LD and M III and was stored up to 96 h. The sperm membrane integrity was evaluated by motility, viable spermatozoa, s...

Apical membranes in many polarized epithelial cells show specialized morphological adaptations that fulfil distinct physiological functions. The air-transporting tubules of Drosophila tracheal terminal cells represent an extreme case of membrane specialization. Here we show that Bitesize (Btsz), a synaptotagmin-like protein family member, is needed for luminal membrane morphogenesis. Unlike in ...

Eukaryotic cells possess a sophisticated membrane system to facilitate diverse functions. Whereas much is known about the nature of membrane systems in interphase, the organization and function of the mitotic membrane system are less well understood. In this study, we show that epsin, an endocytic adapter protein, regulates mitotic membrane morphology and spindle integrity in HeLa cells. Using ...

Antioxidants partially ameliorated the negative effects of reactive oxygen species (ROS) produced during cryopreservation. The objective of the present study was to investigate the effect of cysteine and a water-soluble vitamin E analogue on the quality of frozen-thawed epididymal cat spermatozoa. Epididymal spermatozoa were collected from eight male cats and divided into three aliquots; these ...
