Abstract
The growing global deterioration in several aspects of human health has been partly attributed to hazardous effects of endocrine-disrupting chemicals (EDCs) exposure. Therefore, experts and government regulatory agencies have consistently advocated for studies on the combined effects of EDCs that model human exposure to multiple environmental chemicals in real life. Here, we investigated how low concentrations of bisphenol A (BPA), and phthalates compounds affect the Sertoli cell glucose uptake/lactate production in the testis and male fertility. An EDC mixture containing a detected amount of each chemical compound in humans, called daily exposure (DE), and DE increased in magnitude by 25 (DE25), 250 (DE250), and 2500 (DE2500), and corn oil (control) were administered for six weeks to male mice. We found that DE activated estrogen receptor beta (Erβ) and glucose-regulated protein 78 (Grp 78) and disrupted the estradiol (E2) balance. In addition, DE25, DE250, and DE2500 doses of the EDC mixture via binding with Sertoli cells' estrogen receptors (ERs) inhibited the glucose uptake and lactate production processes by downregulating glucose transporters (GLUTs) and glycolytic enzymes. As a result, endoplasmic reticulum stress (ERS), marked by unfolded protein response (UPR) activation, was induced. The accompanying upregulation of activating transcription factor 4 (ATF4), inositol requiring enzyme-1 (IRE1), C/EBP homologous protein (CHOP), and mitogen-activated protein kinase (MAPK) signaling promoted antioxidant depletion, testicular cell apoptosis, abnormal regulation of the blood-testis barrier, and decreased sperm count. Therefore, these findings suggest that human and wildlife exposure to multiple environmental chemicals can produce a wide range of reproductive health complications in male mammals.

Abstract
Semen parameters can be considered useful predictors of sperm fertility. The objective of this study was to address the question of whether differences in in vivo fertility after the use of different ejaculates could be predicted using sperm kinematics, capacitation status, and sperm penetration ability under commercial pig production conditions. The percentage of capacitated sperm, as assessed by chlortetracycline (CTC) staining, was positively correlated with litter size (p<0.01). Our data suggest that litter size increases in proportion to the number of capacitated spermatozoa. When all semen parameters (kinematics, sperm capacitation status, and sperm penetration ability) and litter size were included in a multiple linear regression analysis, significant associations were found between the percentage of capacitated sperm (B-type), the sperm fertility index as assessed by a sperm penetration assay (SPA), and litter size. This relationship between capacitated sperm and litter size, however, was more predictive for smaller litter groups than larger ones. We found that the percentage of B-type sperm was significantly correlated with historic average litter size. However, there was no significant correlation between the percentage of B-type sperm and historic farrowing rates. To determine the normal range for B-type sperm, the lower limits were established as 30% for small litters (<8 piglets) and 35% for large litters. The overall accuracy of the assay was 92% and 83% for small and large litters, respectively. These results indicate that capacitation status as measured by CTC staining is a useful predictor of sperm fertility, equivalent to SPA. Moreover, original capacitation status exhibited better predictive ability for small litters than for large ones. Therefore, subfertile boars can be identified primarily by capacitation status.

Abstract
OBJECTIVES To increase the yield of fetal nucleated red blood cells (NRBCs) from maternal blood using a discontinuous Percoll gradient and to determine the effects of osmolality on NRBC yield. METHODS Fetal NRBCs were isolated from combined umbilical cord blood and adult female blood, or from maternal blood using single or double Percoll gradients with different osmolalities. Magnetic activated cell sorting was used to enrich isolated NRBCs, and morphological differentiation was performed with Kleihauer-Betke stain. We also isolated fetal NRBCs from 25 10 mL samples of maternal blood and determined fetal sex by fluorescence in situ hybridization (FISH), using X-Y probes. RESULTS For single-density Percoll columns, the greatest number of NRBCs was isolated using 280 mOsm/kg H(2)O with 1.077 g/mL Percoll and 520 mOsm/kg H(2)O with 1.119 g/mL Percoll. Significantly more fetal NRBCs were isolated with double Percoll density gradients than with double-Histopaque gradients (p = 0.043). FISH analysis on NRBC in 25 cases correctly identified 15 male and 9 female euploid fetuses and one Trisomy 21 fetus. CONCLUSION The NRBC enrichment method we present requires less maternal blood and yields more NRBCs compared to previous methods.

Abstract
OBJECTIVE To investigate the high circumcision rate in South Korea and its rapid increase in the short period since its introduction. SUBJECTS AND METHODS From January to December 2000, 5434 South Korean males (or their parents) aged 0-92 years were interviewed in detail about their circumcision status, their age at circumcision, and the possible effect of circumcision on their sexuality. In addition, 267 practising medical doctors were surveyed about their basic understanding of circumcision and phimosis. RESULTS Currently the circumcision rate for high-school boys is > 90% and for those > 70 years old is < 10%. The circumcision rate in 1945 was < 0.1%. When averaged over the whole population, the present South Korean circumcision rate is approximately 60%; the rate has increased dramatically with time and particularly in the past 20 years, when the estimated number of male circumcisions has exceeded the number of male births. Although circumcision in South Korea has been strongly influenced by American culture, it has never been predominantly neonatal. The age at circumcision has continued to decrease and boys are now circumcised at approximately 12 years old. Of those who were circumcised long after they had been sexually active, > 80% reported no noticeable difference in sexuality, but a man was twice as likely to have experienced diminished sexuality than improved sexuality. Of the doctors who were surveyed, 41% carried out circumcision but, unlike in America, gynaecologists and paediatricians rarely did so. Among the doctors, basic knowledge on circumcision and phimosis was generally lacking, regardless of whether they practised circumcision or not. Amongst the factors contributing to the high circumcision rate was the mistaken notion held by both doctors and the general public that circumcision is directly correlated with industrialization and general progress of living standards. Many doctors believe the out-dated and sometimes controversial benefits of circumcision, i.e. prevention of cervical cancer and sexually transmitted diseases, and improved sexuality. Thus the vast majority of doctors recommend circumcision regardless of the patient's age. Peer pressure was also an important contributing factor. CONCLUSION South Korea has an unusual history of circumcision. The mistaken and out-dated notions about circumcision and lack of knowledge of phimosis by physicians seem to be a leading contributory factor to the extraordinarily high circumcision rate.

Abstract
We have developed a transgenic female goat harboring goat beta-casein promoter/human granulocyte colony stimulating factor (G-CSF) fusion gene by microinjection into fertilized one-cell goat zygotes. Human G-CSF was produced at levels of up to 50 microg/ml in transgenic goat milk. Its biological activity was equivalent to recombinant human G-CSF expressed from Chinese hamster ovary (CHO) cell when assayed using in vitro HL-60 cell proliferation. Human G-CSF from transgenic goat milk increased the total number of white blood cells in C57BL/6N mice with leucopenia induced by cyclophosphamide (CPA). The secreted human G-CSF was glycosylated although the degree of O-glycosylation was lower compared to CHO cell-derived human G-CSF.

Abstract
OBJECTIVE To determine aneuploidy frequencies in pellet and swim-up semen fractions from 10 infertile men with severe oligoasthenoteratozoospermia (OAT) who were donating sperm for intracytoplasmic sperm injection and to determine whether the swim-up isolation method would successfully separate aneuploid from haploid sperm. DESIGN Prospective study. SETTING Infertility clinic and molecular genetics laboratory. PATIENT(S) Ten patients with severe OAT. INTERVENTION(S) Cytogenetic analyses by fluorescence in situ hybridization to determine aneuploidy frequencies for chromosomes 1, 13, 18, 21, X, and Y in sperm from swim-up and pellet fractions. MAIN OUTCOME MEASURE(S) Gametic aneuploidy was scored in sperm fractions separated by the swim-up technique and clinical results after intracytoplasmic sperm injection were tabulated. RESULT(S) In all cases, chromosome aneuploidy levels in patients were significantly greater than in controls. The type and percentage of aneuploid sperm for all patients with OAT found in both swim-up and pellet fractions were not different, with the exception of diploid sperm, which remained in the pellet fraction. After ET, 2 (20%) of 10 couples achieved successful pregnancies. CONCLUSION(S) The data show significantly higher rates of diploidy, autosomal disomy and nullisomy, sex chromosome disomy and nullisomy, and total aneuploidy in sperm from all separated fractions obtained from all patients with OAT versus controls. This patient population with OAT may be at increased risk of producing aneuploid offspring.

Abstract
Recent evidence suggests that infertile males donating semen for intracytoplasmic sperm injection (ICSI) may be at an increased risk of transmitting numerical (predominantly sex chromosome) abnormalities to their offspring. The present study was designed to determine aneuploidy in spermatozoa from oligoasthenoteratozoospermic (OAT) patients undergoing ICSI. Aneuploidy frequencies of 12 autosomes and the sex chromosomes were determined by fluorescence in-situ hybridization (FISH) on spermatozoa from fresh ejaculate of nine severe OAT patients and four proven fertile donors. FISH, using directly labelled (fluorochrome-dUTP) satellite or contig DNA probes specific for chromosomes 4, 6, 7, 8, 9, 10, 11, 12, 13, 17, 18, 21, X, and Y, was performed on decondensed spermatozoa. Per chromosome disomy frequencies for autosomes and sex chomosomes in OAT males were 0-5. 4%. In contrast, the disomy frequencies in controls were 0.05-0.2%. The frequency of diploid spermatozoa in OAT patients was 0.4-9.6%; controls showed a mean of 0.04%. Using recently developed formulae, the total aneuploidy in our OAT patient population was estimated to be 33-74%. In contrast, estimates of mean total aneuploidy in the spermatozoa of controls ranged from 4.1 to 7.7%, depending upon method of calculation. Six series of ICSI were performed on five of the OAT patients. Four resulted in no establishment of pregnancy; the others failed to establish ongoing pregnancies. Our cytogenetic data show significantly elevated frequencies of diploidy, autosomal disomy and nullisomy, sex chromosome aneuploidy, and total aneuploidy in OAT patients, which may contribute to the patients' infertility.

Abstract
OBJECTIVE To determine aneuploidy frequencies in sperm from a patient with normal phenotype and 46,XY/45,X mosaicism in somatic cells (peripheral lymphocytes). DESIGN Case report. SETTING Infertility clinic and genetics laboratory. PATIENT A 30-year-old male with primary infertility and moderate oligoasthenoteratozoospermia. INTERVENTION(S) Cytogenetic analysis of somatic cells and determination by fluorescence in situ hybridization of aneuploidy frequencies for the gonosomes (sex chromosomes) and chromosome 18 in sperm from whole and Percoll-separated semen. MAIN OUTCOME MEASURE(S) Somatic and gametic aneuploidy were scored. RESULT(S) Analysis of lymphocyte metaphase cells showed a mosaic 46,XY (90%)/ 45,X (10%) karyotype. Significantly higher frequencies of gonosomal (semen, 1.92% versus 0.70%; Percoll, 1.12% versus 0.46%), and chromosome 18 (semen, 0.89% versus 0.28%; Percoll, 0.26% versus 0.10%) disomy were detected in the sperm of the patient compared with those observed in spermatozoa from a proved fertile control. CONCLUSION(S) Significantly higher frequencies of aneuploid sperm suggest that the patient is at elevated risk of producing offspring with numerical chromosome abnormalities.

Abstract
Recombinant adeno-associated viruses (rAAV) are attractive tools for gene therapy. We designed plasmids in which the human multidrug resistance gene (hMDR1) cDNA was placed downstream from portions of the 5' end of AAV including either a 234-bp cassette or the entire AAV p5 promoter. The drug-resistant phenotype conferred by the P-glycoprotein (Pgp) efflux pump encoded by the hMDR1 cDNA was used to select NIH-3T3 cells transfected with these plasmids. The 234-bp region alone showed promoter activity similar in strength to that of the entire p5 promoter or the retroviral Harvey murine sarcoma virus long terminal repeat (LTR); this result demonstrates that the 234-bp cassette might be used as a small and efficient promoter in rAAV designed to express large genes approaching the packaging limit of AAV particles. After transfection of AAV-MDR1 vectors, the integration of MDR1 sequences into the host cell genome was demonstrated by fluorescent in situ hybridization (FISH). In addition, Southern analysis of low-molecular-weight DNA extracted from drug-resistant cells grown under continuous selection pressure indicated the persistence of nonintegrated AAV-MDR1 plasmids. Coordinate expression of Pgp and human glucocerebrosidase (hGC) was observed in drug-selected NIH-3T3 cells transfected with a bicistronic vector in which MDR1 cDNA was linked to hGC cDNA via the encephalomyocarditis internal ribosome entry site sequence. Moreover, following a single intravenous injection of the bicistronic vector complexed to cationic liposomes into recipient mice, delivery of MDR1 and GC cDNAs was achieved in all the organs we tested. Our results demonstrate that the efficiency of liposomes as vehicles for in vitro and in vivo gene delivery, the advantages of AAV-vectors, and the use of MDR1 as a selectable marker might be successfully combined in gene therapy protocols.

Abstract
Hypoxia-inducible factor 1 (HIF-1) is a basic helix-loop-helix transcription factor that mediates homeostatic responses to hypoxia. HIF-1 is a heterodimer consisting of HIF-1alpha, which is encoded by the HIF1A gene, complexed with HIF-1beta, which is encoded by the ARNT gene. In this paper we report the assignment of Hif1a and HIF1A to mouse chromosome 12 and human chromosome 14, respectively. HIF1A was assigned to human chromosome 14q21-q24 by analysis of somatic cell hybrids and by fluorescence in situ hybridization. Hif1a was localized by interspecific backcross analysis within a region of mouse chromosome 12 encompassing >30 cM that demonstrates conservation of synteny with a region of human chromosome 14 extending from PAX9 at 14q12-q13 to IGHC at 14q32.33.

Abstract
Four types of drinking driver groups were compared with each other and also with two nondrinking driver groups on sensation seeking, social responsibility, and hostility. Groups were also compared on traffic violations, accidents, alcohol consumption, frequency of driving after drinking, frequency of driving impaired, and perception of driving risk taking after drinking. Drivers under the influence apprehended in conjunction with an accident or moving violation had significantly greater alcohol consumption, frequency of driving after drinking, frequency of driving impaired, traffic violations, accidents, and self rating of risk taking after drinking in comparison with other groups.

Abstract
Using an interview and questionnaire format, 358 driving under the influence of alcohol (DUI) first offenders and 141 DUI multiple offenders were compared on measures of personality traits, drinking behavior and problems, and driving behavior and history. In addition, official driving records for the two groups were compared. Results indicated that multiple offenders were significantly higher in hostility, sensation seeking, psychopathic deviance, mania, and depression than first offenders. Multiple offenders were significantly lower in emotional adjustment and assertiveness. Multiple offenders had significantly more nontraffic arrests, accidents, and traffic tickets than first offenders. They also consumed significantly more alcohol, evidenced more alcohol problems, and had higher BACs at the time of arrest than first offenders. Results are discussed in terms of general problem behavior and implications for intervention and treatment.

Abstract
Female DUI offenders who participated in a controlled, random assignment DUI intervention study, the Mississippi DUI Probation Follow-Up Project, were compared to their male counterparts on demographic, drinker status and recidivism variables. In comparison to men, women in the project were less likely to be married, more likely to be between 30 and 50 years of age, less likely to have less than a 9th grade education, less likely to be screened as a high-problem-risk drinker, less likely to have prior DUI and public drunkenness arrests and less likely to recidivate. The effects of short-term rehabilitation, 1 year's probation and administration of the Life Activities Inventory-Current Status Questionnaire (LAI-CSQ) on the long-term recidivism rates of women were examined. The analysis for screened low-problem-risk women was inconclusive due to lack of statistical power. However, the repeated administration of the LAI-CSQ was detrimental for screened high-problem-risk women and tended to be detrimental for women with fewer than 12 years of education. Implications for intervening with female DUIs are discussed.

Abstract
Eight types of drinking driver groups were compared on several personality and behavior traits. It was found that impaired drivers arrested after an accident or moving violation were significantly higher in hostility, psychopathic deviance, nontraffic arrests, frequency of impaired driving, accidents after drinking, and drinks consumed per week than impaired drivers caught in roadblocks. Neither impaired drivers stopped in roadblocks nor impaired drivers never arrested differed from nonimpaired drinking drivers or nondrinking drivers on most measures examined.

Abstract
The sperm penetration assay is an expensive, time-consuming test to assess male fertility in vitro. Although some investigators are enthusiastic in its application, others feel that it is not sensitive or specific enough to be used as part of the routine infertility evaluation. Indeed, this bioassay is not a faithful reproduction of in vivo conditions. However, if the SPA is abnormal, it is unlikely that sperm will fertilize a human ovum in vivo. Conversely, a normal SPA does not guarantee successful in vivo fertilization. No bioassay can be absolute in its predictive value, but false-negative results must be kept to a minimum for this bioassay to be of any clinical significance. Each laboratory performing the SPA should optimize the assay for sensitivity, reproducibility, and minimization of false-negative results and then establish normal and abnormal ranges of its own. If the limitations of the SPA are kept in mind, and if we employ it very selectively, it may still be useful.

Abstract
Multiple regression analysis was used to examine the relationship of five drinking reason factors to drinking locations and consumption variables within a random sample of drinking college students surveyed by telephone. Hypotheses relating self-reported accident involvement after drinking and two specific reason factors - Opposite Sex/Drunkenness and Pleasure - were tested. Both Pleasure and Opposite Sex/Drunkenness were directly related to quantity consumed and to drinking in several away-from-home locations. Opposite Sex/Drunkenness reasons and frequency of drinking in cars significantly contributed to identifying males who reported accident involvement following drinking.
