The progression of our understanding of ribosomal proteins as static building blocks of the ribosome to highly integrated sensors of p53 surveillance and function has achieved a tremendous rate of growth over the past several decades. As the workhorse of the cell, ribosomes are responsible for translating the genetic code into the functional units that drive cell growth and proliferation. The seminal identification of ribosomal protein binding to MDM2, the negative regulator of p53, has evolved into a paradigm for ribosomal protein-MDM2-p53 signaling that extends into processes as diverse as energy metabolism to proliferation...

It is a known fact that abnormal seminal liquid specimens contain abnormal amounts of oxygen free radicals and reactive oxygen species (ROS), and that the use of antioxidant molecules both in vivo and in vitro leads to improvement of semen quality in terms of motility, reduction in DNA damage, with obvious consequences on the fertilization potential. Myo-inositol has been observed to have anti-oxidant properties and be present in much greater concentrations specifically in seminal liquid than in the blood. Moreover, there seems to be a direct relationship between myo-inositol and mitochondrial membrane potential (MMP) and sperm motility...

PURPOSE OF REVIEW: Although the importance of optimizing mothers' health prior to conception and during pregnancy is now well accepted, recent data also implicate health and nutritional status of fathers as contributors to chronic disease risk in their progeny. This brief review will highlight recent epidemiological and experimental studies linking paternal overnutrition, undernutrition, and other forms of stress, to metabolic disease in the offspring. RECENT FINDINGS: The past 2 years have brought tremendous insights into the mechanisms by which paternal exposures can contribute to disease susceptibility in the next generation...

BACKGROUND: Sexual dimorphism occurs widely across the animal kingdom and has profound effects on evolutionary trajectories. Here, we investigate sex-specific gene expression in Ischnura elegans (Odonata: dragonflies and damselflies), a species with pronounced sexual differences including a female-limited colour polymorphism with two female-like gynochrome morphs and one male-mimicking, androchrome morph. Whole-organism transcriptome profiling and sex-biased gene expression analysis was conducted on adults of both sexes (pooling all females as well as separating the three morphs) to gain insights into genes and pathways potentially associated with sexual development and sexual conflict...

The association of ipsilateral renal agenesis and cystic seminal vesicle is a rare congenital syndrome described by Zinner in 1914. The cases of two patients with this syndrome are presented, one of them associated with infertility, the other with cryptorchidism and testicular pain. A brief review of the literature is undertaken, regarding the main clinical and imaging implications, and the developmental anomalies that are involved in this unusual congenital anomaly are analyzed.

BACKGROUND: Benign tissue from a tumor-containing organ is commonly the only available source for obtaining a patient's unmutated genome for use in cancer research. While it is critical to identify histologically normal tissue that is independent of the tumor lineage, few additional considerations are applied to the choice of this material for such measurements. METHODS: Normal formalin-fixed, paraffin-embedded seminal vesicle, and urethral tissues, in addition to whole blood, were collected from 31 prostate cancer patients having undergone radical prostatectomy...

Water availability is a major limiting factor for crop production, making drought adaptation and its many component traits a desirable attribute of plant cultivars. Previous studies in cereal crops indicate that root traits expressed at early plant developmental stages, such as seminal root angle and root number, are associated with water extraction at different depths. Here, we conducted the first study to map seminal root traits in barley ( L.). Using a recently developed high-throughput phenotyping method, a panel of 30 barley genotypes and a doubled-haploid (DH) population (ND24260 × 'Flagship') comprising 330 lines genotyped with diversity array technology (DArT) markers were evaluated for seminal root angle (deviation from vertical) and root number under controlled environmental conditions...

Circulatory arrest (CA) remains a major unresolved public health problem in the United States; the annual incidence of which is ~0.50 to 0.55 per 1000 population. Despite seminal advances in therapeutic approaches over the past several decades, brain injury continues to be the leading cause of morbidity and mortality after CA. In brief, CA typically results in global cerebral ischemia leading to delayed neuronal death in the hippocampal pyramidal cells as well as in the cortical layers. The dynamic changes occurring in neurons after CA are still unclear, and predicting these neurological changes in the brain still remains a difficult issue...

BACKGROUND: According to recent studies, prostate cancer is the second most common cancer among Iranian men. Radical prostatectomy has been considered the gold standard treatment in patients with clinically localized prostate cancer. Gleason score, PSA density, and PSA velocity are some of the parameters used to predict adverse pathologic features. OBJECTIVES: The aim of this study was to evaluate the prognostic value of PSA density and Gleason score in predicting adverse pathologic features in patients with localized prostate cancer who undergo radical prostatectomy...

The slope of the set size function as a critical statistic first gained favor in the 1960s due in large part to the seminal papers on short-term memory search by Saul Sternberg and soon, many others. In the 1980s, the slope statistic reemerged in much the same role in visual search as Anne Treisman and again, soon many others brought that research topic into great prominence. This note offers the historical and current perspective of the present author, who has devoted a significant portion of his theoretical efforts to this and related topics over the past 50 years...

Scarcely understood defects lead to asthenozoospermia which results in poor fertility outcomes. Incomplete knowledge of these defects hinders the development of new therapies and reliance on interventional therapies, such as in vitro fertilization, increases. Sperm cells, being transcriptionally and translationally silent, necessitate the proteomic approach to study the sperm function. We have performed a differential proteomics analysis of human sperm and seminal plasma and identified and quantified 667 proteins in sperm and 429 proteins in seminal plasma dataset which were used for further analysis...

Individuals born with low birth weight (LBW) risk cardiometabolic complications later in life. However the impact of LBW on general health status and male reproductive function has been scantly analysed. We investigated the clinical and seminal impact of different birth weights (BW) in white-European men presenting for primary couple's infertility. Demographic, clinical, and laboratory data from 827 primary infertile men were compared with those of 373 consecutive fertile men. Patients with BW ≤2500, 2500-4200, and ≥4200gr were classified as having LBW, normal (NBW), and high BW (HBW), respectively...

The fall colors are signs of chlorophyll breakdown, the biological process in plants that generates phyllobilins. Most of the abundant natural phyllobilins are colorless, but yellow phyllobilins (phylloxanthobilins) also occur in fall leaves. As shown here, phylloxanthobilins are unique four-stage photoswitches. Which switching mode is turned on is controlled by the molecular environment. In polar media, phylloxanthobilins are monomeric and undergo photoreversible Z/E isomerization, similar to that observed for bilirubin...
