During mammalian testis development distinct generations of fetal and adult Leydig cells arise. Luteinising hormone (LH) is required for normal adult Leydig cell function and for the establishment of normal adult Leydig cell number but its role in the process of adult Leydig cell differentiation has remained uncertain. In this study we have examined adult Leydig cell differentiation in gonadotr...

We determined nearly complete flagellin gene sequences for Borrelia burdgdorferi sensu lato isolates (11 isolates obtained from Ixodes persulcatus ticks and patients in Hokkaido, Japan, and 1 European isolate) representing six different restriction fragment length polymorphism (RFLP) ribotype groups following cloning of the PCR-amplified genes. These sequences were aligned with those of represe...

Objective: Carob (Ceratonia siliqua L.) is an evergreen tree with fruits that have potent antioxidant activity. The aim of this study was to investigate alleviative effects of carob fruit hydro-alcoholic extract (CFHAE) against reproductive toxicity induced by lead (Pb) in male mice. Material and Methods: Forty-two NMRI adult male mice were randomly categorized into 7 groups (N=6). Group ...

A myosin for RNA Pol II T ranscription gets a boost from myosin VI, according to fi ndings from Sarah Vreugde (DIBIT Scientifi c Institute, Milano, Italy) and colleagues. The motor might drag genes into transcription neighborhoods. While trying to understand the function of myosin VI, Vreugde noticed that its localization pattern looked much like that of RNA polymerase II. The authors then show...

BACKGROUND Neuromuscular disorders are a clinically, pathologically, and genetically heterogeneous group. Even for the experienced clinician, an accurate diagnosis is often challenging due to the complexity of these disorders. Here, we investigated the utility of next generation sequencing (NGS) in early diagnostic algorithms to improve the diagnosis for patients currently lacking precise molec...

The wild-type and temperature-sensitive (ts) repressor genes were cloned from the temperate mycobacteriophage L1 and its mutant L1cIts391, respectively. A sequencing analysis revealed that the 131st proline residue of the wild-type repressor was changed to leucine in the ts mutant repressor. The 100% identity that was discovered between the two DNA regions of phages L1 and L5, carrying the same...

Cancer stem-like cells are thought to contribute to tumor recurrence. The anthrax toxin receptor 1 (ANTXR1) has been identified as a functional biomarker of normal stem cells and breast cancer stem-like cells. Primary stem cell-enriched basal cells (CD49f(+)/EpCAM(-)/Lin(-)) expressed higher levels of ANTXR1 compared with mature luminal cells. CD49f(+)/EpCAM(-), CD44(+)/EpCAM(-), CD44(+)/CD24(-...

INTRODUCTION Pseudomonas aeruginosa (P. aeruginosa) is one of the primary opportunistic pathogens responsible for nosocomial infections. Aminoglycosides are an import ant component of antipseudomonal chemotherapy. The inactivation of drugs by modifying enzymes is the most common mechanism of aminoglycoside resistance. OBJECTIVES The inactivation of aminoglycosides by modifying enzymes is the ...

OBJECTIVE We aimed to determine the frequency of all known forms of congenital muscular dystrophy (CMD) in a large Australasian cohort. METHODS We screened 101 patients with CMD with a combination of immunofluorescence, Western blotting, and DNA sequencing to identify disease-associated abnormalities in glycosylated alpha-dystroglycan, collagen VI, laminin alpha2, alpha7-integrin, and selenop...
