The male-specific Fruitless proteins (FruM) act to establish the potential for male courtship behavior in Drosophila melanogaster and are expressed in small groups of neurons throughout the nervous system. We screened ∼1000 GAL4 lines, using assays for general courtship, male-male interactions, and male fertility to determine the phenotypes resulting from the GAL4-driven inhibition of FruM expr...

The semen analysis is the main diagnostic tool for evaluating the male fertility potential. The standard semen analysis includes evaluation of the sperm concentration, motility, and their morphology. The most important question is whether the results from semen analysis may be accurate markers for male fertility. Therefore, we retrospectively studied sperm quality among men attending the infert...

Restoration of polycyclic aromatic hydrocarbon- (PAH-) polluted sites is presently a major challenge in agroforestry. Consequently, microorganisms with PAH-degradation ability and soil fertility improvement attributes are sought after in order to achieve sustainable remediation of polluted sites. This study isolated PAH-degrading bacteria from enriched cultures of spent automobile engine-oil po...

In recent years, survival rates of cancer patients have increased, resulting in a shift of focus from quantity to quality of life. A key aspect of quality of life is fertility potential; patients suffering from iatrogenic infertility often become depressed. Since many cancer therapies-chemotherapy, radiotherapy and/or surgery-and even cancer itself have detrimental effects on the male reproduct...

Recent advances in nuclear transfer technology for derivation of patient-specific stem cells have opened up new avenues of therapy for various human diseases. However, a major bottleneck is the severe shortage of human donor oocytes. Egg-sharing in return for subsidized fertility treatment has been suggested as an ethically justifiable and practical solution to ease the shortage of donor oocyte...

in recent years, preservation of fertility in women has been of great importance, especially in patients exposed to deleterious conditions on fertility. thus, cryopre-servation of human gametes, embryos and ovarian tissue has become an essential part of assisted reproduction. this approach limits the number of embryos transferred, while supernumerary oocytes and/ or embryos can be used in subse...

 The nucleus of mature sperm contains a complex population of transcripts such as mRNAs and miRNAs which expressed and accumulated during process of spermatogenesis however in spermatozoa, transcription is inert. The spermatozoa do not have cytoplasmic ribosomal compounds and translation apparatus. However, spermatozoa can translate cytoplasmic mRNAs de novo, using mitochondrial poly...

Garlic (Allium sativum L.) cannot produce seed because it is a sterile plant. For studying bolting and determination of pollen fertility, 68 Iranian garlic clones were gathered from different parts of Iran and evaluated in Research Field of Horticultural Department, Faculty of Agriculture, Bu-Ali Sina University in 2010-2011 and 2011-2012. For determining the pollen fertility, some tests includ...
