Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

The Relationship Between Serum Growth Hormone, Seminal Plasma Growth Hormone, and Sperm Parameters in Patients with Acromegaly in Remission

open access: yesEndocrinology Research and Practice
Objective: The influence of serum insulin-like growth factor-1 (IGF-1) and growth hormone (GH) on sperm parameters has been previously described in patients with acromegaly. However, the relationship between local GH/IGF-1 with systemic levels and sperm

Measurement of Activity and Concentration of Paraoxonase 1 (PON-1) in Seminal Plasma and Identification of PON-2 in the Sperm of Boar Ejaculates

open access: yes, 2015
This study revealed and characterised the presence of the antioxidant enzymes paraoxonase (PON) type 1 (PON-1, extracellular) and type 2 (PON-2, intracellular) in boar semen. To evaluate PON-1, an entire ejaculate from each of ten boars was collected and

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

Comparison of oxidant and antioxidant status of seminal plasma and spermatozoa of several fish species

open access: yesCzech Journal of Animal Science, 2013
Oxidant and antioxidant activity in seminal plasma was compared with that in spermatozoa of teleost (common carp Cyprinus carpio and brook trout Salvelinus fontinalis) and chondrostean (Russian sturgeon Acipenser gueldenstaedtii, Siberian sturgeon ...

Stage‐Dependent β‐Synuclein Links MRI and Cognitive Decline in Alzheimer's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Synaptic degeneration drives cognitive decline in Alzheimer's disease (AD), but synaptic biomarkers are scarce. Brain‐enriched β‐synuclein emerged as a synaptic damage marker. We investigated its diagnostic, prognostic, and structural correlates across the AD continuum.

Application of seminal plasma in sex-sorting and sperm cryopreservation [PDF]

open access: yes, 2008
Substantial dilution of boar semen during processing decreased the concentration of seminal plasma, perhaps contributing to the decline in sperm quality after cryopreservation and sex-sorting.

Comparative Analysis of Proteomic Characteristics in Seminal Plasma Between Horses and Donkeys

open access: yesAnimals
Horses and donkeys, as integral members of the equine family, exhibit distinct reproductive capabilities and characteristics. Seminal plasma, the fluid component of semen, contains a variety of proteins that play critical roles in sperm function and ...
