PURPOSE Testosterone and luteinizing hormone secretion is reportedly impaired in infants born with cryptorchidism. To better characterize this phenomenon, we studied a range of hormones that normally increase in boys during the first few months of life. MATERIALS AND METHODS A case-control study was conducted of boys with nonsyndromic cryptorchidism(More)
Development of the fetal gubernaculum is a prerequisite for testicular descent and dependent on insulin-like 3 and androgen, but knowledge of downstream effectors is limited. We analyzed transcript profiles in gubernaculum and testis to address changes occurring during normal and abnormal testicular descent in Long Evans wild-type (wt) and cryptorchid (orl)(More)
Phenotype results from interactions between genetics and environment, but for most environmental chemical exposures, such interactions are theoretical. The phenotypic response of the testis to in utero dibutyl phthalate (DBP) exposure was compared between two strains of Long-Evans (LE) rats, the orl substrain with inherited cryptorchidism and an outbred(More)
Parkinson's disease (PD), the second most common neurodegenerative disorder after Alzheimer's disease, is characterized by the loss of nigral dopaminergic neurons. PD leads to a series of clinical symptoms, including motor and non-motor disturbances. α-synuclein, the major component of Lewy bodies, is a hallmark lesion in PD. In this review, we concentrate(More)
INTRODUCTION Parkinson's disease is a common neurodegenerative disorder mainly caused by the loss of nigral dopaminergic neurons, of which the pathogenesis remains essentially unknown. Current therapeutic strategies help manage signs and symptoms but have no effect in disease modification. Over the past several decades, scientists have devoted a lot of(More)
PURPOSE Failure of testicular descent occurs in about 65% of spontaneously cryptorchid Long-Evans orl rats. Development of the fetal gubernaculum is dependent on expression of leucine rich G protein coupled receptor (also known as G protein coupled receptor affecting testicular descent) and its ligand, insulin-like 3. We studied testicular descent and mRNA(More)
RATIONALE A dural arteriovenous fistula (DAVF) refers to an abnormal direct connection between an intracranial artery and a dural venous sinus. A DAVF presenting with parkinsonism is rare, and is therefore easily misdiagnosed. Therefore, early consideration of DAVF in the differential diagnosis of reversible parkinsonism is necessary. PATIENT CONCERNS We(More)
OBJECTIVE Epidemiological studies have investigated the association between Parkinson disease (PD) occurrence and the risk of brain tumors, while the results remain controversial. We performed a meta-analysis to clarify the exact relationship between PD and brain tumors. METHODS A systematic literature search was conducted using PubMed, Embase,(More)
