Effects of Photoperiod and Subcutaneous Melatonin Implants on the Reproductive Status of Adult White-footed Mice(Peromyscus leucopus)
implant melatonin photoperiod white-footed mouse Peromyscus leucopus testosterone
2009/2/19
The reproductive consequences of photoperiod and melatonin administration were compared in adult white-footed mice (Peromyscus leucopus). Animals were exposed either to a long photoperiod (16 hours ...
The effects of spinal cord injury on the status of messenger ribonucleic acid for TRPM 2 and androgen receptor in the prostate of the rat
spinal cord messenger ribonucleic TRPM 2 rat
2009/2/17
The prostate is one of the male accessory sex glands that produce fluid components of the seminal plasma. In addition to androgen, a normal innervation of the prostate is believed to be important ...
Use of peanut agglutinin to assess the acrosomal status and the zona pellucida-induced acrosome reaction in stallion spermatozoa
FITC-PNA hemizona acrosome reaction
2009/2/17
Peanut agglutinin (PNA) was used to assess the sperm acrosomal status and the acrosome reaction during gamete interaction in the equine species. PNA exclusively binds to the outer acrosomal membra...
The nuclear status of human sperm cells by TEM image cytometry:nuclear shape and chromatin texture in semen samples from fertile and infertile men
human sperm cells TEM image cytometry nuclear shape chromatin texture semen samples
2009/2/12
Changes in nuclear size, shape, and chromatin texture during spermiogenesis and epididymal transport of human sperm were recently analyzed using transmission electron microscopy (TEM) image cytome...
Thiol-disulfide status and acridine orange fluorescence of mammalian sperm nuclei
Spermatozoa maturation fertility protamine hamster acridine orange
2009/2/11
The relationship between thiol-disulfide status and acridine orange fluorescence of testicular, epididymal, and ejaculated spermatozoa in several mammalian species was investigated. Spermatozoa were...
The fix vital stain method. Simultaneous determination of viability and acrosomal status of bovine spermatozoa
Acrosomal evaluation vital staining Hoechst bisbenzimide
2009/2/7
A rapid, accurate and precise method for simultaneous determination of acrosomal status and viability of bull spermatozoa is introduced and evaluated. The method involves fixation of semen with glut...
Effect of sperm-associated antibodies on the acrosomal status of human sperm
Antisperm antibodies acrosome reaction infertility spermatozoa
2009/2/6
The acrosomal status of human sperm was assessed by the specific binding of Pisum sativum lectin to the acrosomal matrix. Immunoglobulin G (IgG) fractions of plasmas that were positive for IgG antis...
Assessment of the acrosomal status of ram spermatozoa by RCA lectin-binding and partition in an aqueous two-phase system
acrosomal status ram spermatozoa RCA lectin-binding partition aqueous two-phase system
2008/12/25
The acrosome reaction is an important marker for sperm function. Because different laboratory techniques may be used to detect this exocytotic process, the objective of this study was to investiga...
Serotonin Concentration, Synthesis, Cell Origin, and Targets in the Rat Caput Epididymis During Sexual Maturation and Variations Associated With Adult Mating Status:Morphological and Biochemical Studies
5-hydroxytryptamine tryptophan hydroxylase neuroendocrine cells male reproduction serotonin receptor spermatozoa
2008/12/24
The caput epididymis of some mammals contains large quantities of serotonin whose origin, targets, and physiological variations have been poorly studied. We combined morphological and biochemical...
Effect of Seminal Plasma Fractions From Entire and Vasectomized Rams on the Motility Characteristics, Membrane Status, and In Vitro Fertility of Ram Spermatozoa
Seminal Plasma Fractions Entire Vasectomized Rams Motility Characteristics Membrane Status
2008/12/24
Whole seminal plasma from ram semen collected before and after vasectomy was separated into 2 fractions, supernatant and pellet of vesicles, and their protein profiles characterized by one-dimens...
Testicular Torsion Alters the Presence of Specific Proteins in the Mouse Testis as Well as the Phosphorylation Status of Specific Proteins
Oxidative stress testicular proteins
2008/12/23
Testicular torsion followed by torsion repair induces an ischemia-reperfusion injury to the testis that can render the testis aspermatogenic. Previous results have demonstrated this loss of sp...
