FMR1 CGG Repeat Distribution and Linked Microsatellite-SNP Haplotypes in Normal Mexican Mestizo and Indigenous Populations

ABSTRACT The (CGG)n repeat size distribution in the FMR1 gene was studied in healthy individuals: 80 X chromosomes of Mexican Mestizos from Mexico City and 33 X chromosomes of Mexican Amerindians from three indigenous communities (Purepechas, Nahuas, and Tzeltales), along with alleles and haplotypes defined by two microsatellite polymorphic markers (DXS548 and FRAXAC1) and two single nucleotide polymorphisms (FMRA and FMRB). Genetic frequencies of Mestizo and Amerindian subpopulations were statistically similar in almost all cases and thus were considered one population for comparisons with other populations. Sixteen (CGG)n alleles in the 17–38 size range were observed, and the most common were the 25 (38.0%), 26 (28.3%), and 24 (12.3%) repeat alleles. This pattern differs from most other populations reported, but a closer relation to Amerindian, European, and African populations was found, as expected from the historical admixture that gave rise to Mexican Mestizos. The results of the CA repeats analysis at DXS548-FRAXAC1 were restricted to nine haplotypes, of which haplotypes 7-4 (52.2%), 8-4 (23.8%), and 7-3 (11.5%) were predominant. The modal haplotype 7-4, instead of the nearly universal haplotype 7-3, had been reported exclusively in Eastern Asian populations. Likewise, only seven different FRAXAC1-FMRA-FMRB haplotypes were observed, including five novel haplotypes (3TA, 4TA, 3–A, 4–A, and 5–A), compared with Caucasians. Of these, haplotypes –A (78.7%) and 3–A (13.2%) were the most common in the Mexican population. These data suggest a singular but relatively low genetic diversity at FMR1 in the studied Mexican populations that may be related to the recent origin of Mestizos and the low admixture rate of Amerindians.
ANIMAL WELFARE PERCEPTIONS OF THE U.S. PUBLIC AND COW-CALF PRODUCERS

Abstract The U.S. livestock industry is increasingly faced with pressure to adjust practices in response to societal concerns—specifically related to farm animal welfare. Using best-worst scaling, we determine which practices the U.S. public and cow-calf producers view as the most effective and most practical practices to improve beef cattle welfare. Latent class models are used to understand heterogeneity within and across the public and producers. Fresh, clean feed and water was viewed by most groups as both effective and practical. Furthermore, castrate with pain control and dehorn with pain control were seen as the least effective and practical practices.
Evaluation of a two-centimeter lateral surgical margin for excision of grade I and grade II cutaneous mast cell tumors in dogs.

OBJECTIVE To evaluate completeness of excision and clinical outcome in dogs with cutaneous mast cell tumors (MCTs) excised with a lateral margin of 2 cm and a deep margin of 1 fascial plane. DESIGN Prospective study. ANIMALS 16 client-owned dogs with 1 or more cutaneous MCTs. PROCEDURE Excision of MCTs was performed with a 2-cm lateral margin and a deep margin of 1 fascial plane. Histologic tumor grading was performed; surgical margins were categorized as complete or incomplete. Follow-up information was obtained via repeat examination of the dogs by veterinarians or client-completed questionnaires. RESULTS 4 grade I and 19 grade II cutaneous MCTs were evaluated. Overall, 21 (91%) MCTs were completely excised; 2 grade II tumors had foci of mast cells at the 2-cm margin. Two dogs received adjunctive treatments following surgery. Follow-up information was available for all dogs (median follow-up period, 379 days; range, 51 to 538 days); no local recurrence was detected during this time. De novo MCTs were detected in 3 of 16 dogs at 37, 54, and 154 days after surgery. Via Kaplan-Meier analysis, median survival time and disease-free interval were both > 538 days (medians not yet reached). No prognostic variables were identified. CONCLUSIONS AND CLINICAL RELEVANCE Excision with a 2-cm lateral margin and a deep margin of 1 fascial plane may result in satisfactory excision of grades I and II MCTs in dogs, with recurrence rates similar to those reported previously. Use of these margins may minimize complications associated with larger local tumor resection.

Human Immunodeficiency Virus Type 1 Strains R5 and X4 Induce Different Pathogenic Effects in hu-PBL-SCID Mice, Depending on the State of Activation/Differentiation of Human Target Cells at the Time of Primary Infection

ABSTRACT In a previous study, we had found that the extent of T-cell dysfunctions induced by a T-tropic strain of human immunodeficiency virus type 1 (HIV-1) in SCID mice reconstituted with human peripheral blood lymphocytes (hu-PBLs) (hu-PBL-SCID mice) was related to the in vivo state of activation of the human lymphocytes. In this article, we compared the effect of infection of hu-PBL-SCID mice with either T-tropic (X4) or M-tropic (R5) strains of HIV-1 by performing virus inoculation at either 2 h or 2 weeks after the hu-PBL transfer, when the human T cells exhibited a marked activation state or a predominant memory phenotype, respectively. A comparable level of infection was found when hu-PBL-SCID mice were challenged with either the SF162 R5 or the IIIB X4 strain of HIV at 2 h postreconstitution, while at 2 weeks, the R5 virus infection resulted in a higher level of HIV replication than the X4 virus. The R5 strain induced a marked human CD4+ T-cell depletion along with a drop in levels of human immunoglobulin M in serum and release of soluble factors at both infection times, while the X4 virus induced severe immune dysfunctions only at 2 h. Of interest, injection of hu-PBLs into SCID mice resulted in a marked up-regulation of CCR5 on human CD4+ T cells. The percentage of CXCR4+cells did not change after transplantation, even though a significant decrease in antigen expression was observed. Comparative experiments with two molecular clones of HIV-1 (X4 SF2 and R5 SF162) and two envelope recombinant viruses generated from these viruses showed that R5 viruses (SF162 and the chimeric env-SF162-SF2) caused an extensive depletion of human CD4+ T cells in SCID mice at both 2 h and 2 weeks after reconstitution, while the X4 viruses (SF2 and the chimeric env-SF2-SF162) induced CD4 T-cell depletion only when infection was performed at the 2-h reconstitution time. These results emphasize the importance of the state of activation/differentiation of human CD4+ T cells and gp120-coreceptor interactions at the time of primary infection in determining HIV-1 pathogenicity in the hu-PBL-SCID mouse model.
Inflammation markers and risk factors for recurrence in 35 patients with a posttraumatic chronic subdural hematoma: a prospective study.

OBJECT To evaluate the role of local inflammation in the pathogenesis and postoperative recurrence of chronic subdural hematoma (CSDH), the authors conducted an investigation in a selected group of patients who could clearly recall a traumatic event and who did not have other risk factors for CSDH. Inflammation was analyzed by measuring the concentration of the proinflammatory and inflammatory cytokines interleukin (IL)-6 and IL-8. The authors also investigated the possible relationship between high levels of local inflammation that were measured and recurrence of the CSDH. METHODS A prospective study was performed between 1999 and 2001. Thirty-five patients who could clearly recall a traumatic event that had occurred at least 3 weeks previously and who did not have risk factors for CSDH were enrolled. All patients were surgically treated by burr hole irrigation plus external drainage. The concentration of inflammatory cytokines was very high in the lesion, whereas it was normal in serum. In five cases in which recurrence occurred, concentrations of both IL-6 and IL-8 were significantly increased (p < 0.01) in comparison with cases without a recurrence. In a layering hematoma, the IL-6 and IL-8 concentrations were significantly higher (p < 0.05). Layering CSDHs were also significantly correlated with recurrence. Trabecular hematoma had the lowest cytokine levels and the longest median interval between trauma and clinical onset. The interval from trauma did not significantly influence recurrence, although it did differ significantly between the trabecular and layering CSDH groups. Concentrations of IL-6 and IL-8 in the CSDHs did not differ significantly in relation to either the age of the hematoma (measured as the interval from trauma) or the age of the patient. CONCLUSIONS Brain trauma causes the onset of an inflammatory process within the dural border cell layer; high levels of inflammatory cytokines were significantly correlated with recurrence and layering CSDH. A prolonged postoperative antiinflammatory medicine given as prophylaxis may help prevent the recurrence of a CSDH.
What Prevents Professional Drivers from Following Physicians’ Cardiologic Advice?

Background: There is a scarcity of published studies of the effects of cardiac counselling among professional drivers (PD). Aims of the study were: (1) to examine explanatory variables for two classical ‘driver’ risk factors – body mass index (BMI), and smoking – and to analyse the interrelations among smoking cessation, losing weight and work-related life changes; (2) to assess the effectiveness of risk factor counselling after 6 months, and (3) to gain insight into possible discrepancies between PD perception of needed changes and compliance with the physician’s advice. Methods: There were 4 groups of male PD: 13 with ischemic heart disease, 12 hypertensives, 10 borderline hypertensives and 34 normotensives. Baseline cardiovascular risk factors as well as occupational and behavioral data were assessed via questionnaire. The counselling was aimed at smoking cessation, weight loss and promoting leisure-time physical activity. Qualitative methods were used to assess PD perceptions about the work environment and health promotion. Results: Baseline smoking intensity was best predicted by the total burden of occupational stress and number of smoking years. Baseline BMI was best predicted by long work hours behind the wheel, low availability of attachment outside work and low self-reported job strain. Self-initiated smoking cessation was best predicted by few smoking years, low coffee intake and admitting fear during driving. Physical activity was significantly increased after 6 months. Losing weight was associated with: quitting or diminishing smoking and making other, work-related, life changes. None of the heavy smokers decreased their daily number of cigarettes after 6 months, although expressing the need to do so in self-generated statements. Conclusions: Exposure to occupational stressors, mainly, long work hours and the concomitant denial of job strain, in combination with low availability of social attachment outside work, could contribute to maintenance of maladaptive behavior in PD. These findings could serve as a basis for designing standardized intervention trials and suggest that modification of the work environment, with participation of the drivers, is a needed component of such trials. Particular attention should be paid to the length and scheduling of work shifts.
Boom‐Baby CEOS, Career Experience, and Risk Taking: A Natural Experiment Using Chinese Ceos’ Growth Paths

China's economy represents a unique experimental environment, in that it has undergone a successful transformation from a planned to a more open system. Leveraging this natural experimental setting, this study examines the impacts of CEOs’ formative experiences on their risk‐taking behavior. Two events likely constitute formative experiences for CEOs: economic reforms that commenced in 1978 and their prior career experiences. In turn, CEOs’ risk tolerance attitudes likely reflect the influences of these significant events. The results show that CEOs who experienced economic reforms in their early adult life exhibit higher risk‐taking likelihood and greater risk tolerance than those who grew up during the planned economy era. Furthermore, firm performance achieved by CEOs’ risk taking is significantly better when CEOs originally started working in and then remained within business sectors.
German Right-Wing Party AfD Finds More Support in Rural Areas with Aging Populations

This study examines in which setting the German political party Alternative for Germany (Alternative fur Deutschland, AfD) performed well in the 2017 parliamentary elections. The AfD’s popularity was relatively high in electoral districts with an above-average amount of craft businesses, a disproportionately high amount of older residents and workers in the manufacturing sector, and—applicable mainly to western German electoral districts—where the disposable household income was lower than the national average. The unemployment rate in the electoral districts and the share of foreigners in the population affect the AfD’s popularity to a lesser extent. Generally, the AfD performs better in rural areas with negative demographic trends—a phenomenon that occurs more frequently in eastern German districts than in western districts. This allows for the conclusion that perspective is lacking among those living in rural areas with negative demographic developments.
Barriers to worldwide institutionalization of social and environmental disclosure

ABSTRACT This study analyzes how groups of organizations that share their social and environmental information are formed in a similar way to identify barriers to the homogenization of social and environmental disclosure (SED) at the international level. Based on a sample of observations of listed firms from six different countries, results suggest that SED does not homogenize globally, spontaneously, because of cultural and geographical barriers. The institutions of environmental disclosure (ED) and social disclosure (SD) are different, thus forming different organizational fields at the international level. The spoken language is a barrier to the international isomorphism of ED and therefore to its comparability. However, language is a less important barrier to SD. When cultural institutions are weaker or have the same roots as North American institutions, cultural diversity does not stop the homogenization of the SD. Moreover, the ED is more isomorphic/comparable at the global level than SD, while the SD is more isomorphic/comparable at the level of culturally distinguishable subsets than ED.
Concurrent high expression of human telomerase reverse transcriptase and human nonmetastatic clone 23 in high‐grade squamous intraepithelial neoplasia and squamous cell carcinoma of uterine cervix

Human telomerase reverse transcriptase (hTERT) and human nonmetastatic clone 23 (nm23-H1) may be separately involved in tumor progression of uterine cervix. We therefore investigate the correlations of hTERT and nm23-H1 in cervical carcinogenesis and further check their application. One hundred and twenty-eight cervical tissues, including 48 squamous cell carcinoma (SCC), 36 high-grade cervical intraepithelial neoplasia (CIN) (CIN 2 and CIN 3), 20 low-grade CIN 1, and 24 normal cases, were collected for immunohistochemical expression of hTERT and nm23-H1. Spearman rank correlation analysis was applied to assess their correlation in these samples. The Fisher exact or Chi-square test was used to evaluate the expression of hTERT or nm23-H1 among each subgroup. The sensitivity, specificity, positive and negative predictive values (PPV and NPV), and accuracy of hTERT and/or nm23-H1 were calculated for the prediction of high-grade CIN and SCC. We found normal cervix and CIN 1 samples had concurrent low expression of hTERT and nm23-H1, whereas high-grade CIN and SCC samples had concurrent high immunoreactivities. The hTERT alone and hTERT or nm23-H1 in combination had better sensitivity, NPV, and accuracy. The nm23-H1 alone as well as hTERT and nm23-H1 in combination had better specificity and PPV. Our results reveal a significantly positive relationship between expression of hTERT and nm23-H1 in normal and neoplastic tissues of uterine cervix. We suggest high expression of hTERT alone and hTERT or nm23-H1 in combination can be offered additional molecular information correlated with high-grade CIN and SCC
The risk of fracture among patients with psoriatic arthritis and psoriasis: a population-based study

Objective To determine the risk of fracture and osteoporosis among patients with psoriatic arthritis (PsA) and psoriasis, compared with the general population and patients with rheumatoid arthritis (RA). Methods A population-based cohort study was performed in The Health Improvement Network in the UK using data from 1994 to 2014. Patients aged 18–89 years with PsA or psoriasis and up to five unexposed controls matched by practice and start date within that practice were included. Patients with RA and matched controls were included for comparison. Severe psoriasis was defined by a code for psoriasis and either phototherapy or a systemic medication for psoriasis. Incidence and adjusted HRs (aHR) for fracture (all, hip, vertebral) were calculated. Results Patients with PsA (n=9788), psoriasis (n=158 323) and controls (n=821 834) were identified. Patients with PsA had an elevated risk of all fracture aHR 1.26 (1.06 to 1.27). Patients with mild psoriasis had elevated risk of all fractures, vertebral and hip fracture: aHR 1.07 (1.05 to 1.10), 1.17 (1.03 to 1.33) and 1.13 (1.04 to 1.22). Patients with severe psoriasis had significantly elevated risk of all fracture and vertebral fracture: aHR 1.26 (1.15 to 1.39) and 2.23 (1.54 to 3.22). Conclusions PsA and psoriasis are associated with an elevated risk for fracture.
Wearable Textile Half-Mode Substrate-Integrated Cavity Antenna Using Embroidered Vias

A wearable textile antenna based on the fundamental mode of a half-mode substrate-integrated semicircular cavity is presented. The antenna operates around 5 GHz and is manufactured with two layers of silver fabric conductors, on the top and bottom of a low-permittivity low-loss foam with minimal water absorption. The vias are realized with five passes of conductive yarn with a diameter of 0.12 mm placed every 1 mm. Their precise arrangement is obtained using computerized embroidery. Compared to other antenna concepts, this design features minimal manufacturing complexity as it does not require accurate patterned cutting of textile conductors. Good isolation from the human body and robustness in terms of deformation are further key characteristics of this structure. This letter provides design guidelines and investigates realistic issues associated with the manufacturing technique. A good agreement between simulated and measured performance with a gain of 7.2 dB validates the concept.
Impact of late treatment-related toxicity on quality of life among patients with head and neck cancer treated with radiotherapy.

PURPOSE To investigate the impact of treatment-related toxicity on health-related quality of life (HRQoL) among patients with head and neck squamous cell carcinoma treated with radiotherapy either alone or in combination with chemotherapy or surgery. PATIENTS AND METHODS The study sample was composed of 425 disease-free patients. Toxicity was scored according to the European Organisation for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) late radiation-induced morbidity scoring system. HRQoL was assessed using the EORTC Quality of Life Questionnaire C30. These assessments took place at 6, 12, 18, and 24 months after completion of radiotherapy. The analysis was performed using a multivariate analysis of variance. RESULTS Of the six RTOG scales investigated, two significantly affected self-reported HRQoL, salivary gland (RTOG(xerostomia)) and esophagus/pharynx (RTOG(swallowing)). Although RTOG(xerostomia) was reported most frequently, HRQoL was most affected by RTOG(swallowing), particularly in the first 18 months after completion of radiotherapy. CONCLUSION Late radiation-induced toxicity, particularly RTOG(swallowing) and RTOG(xerostomia), has a significant impact on the more general dimensions of HRQoL. These findings suggest that the development of new radiation-induced delivery techniques should not only focus on reduction of the dose to the salivary glands, but also on anatomic structures that are involved in swallowing.
Identification in situ and dynamics of bacteria on limnetic organic aggregates (lake snow)

Microbial assemblages on large organic aggregates (lake snow) of Lake Constance, Germany, were analyzed with rRNA-directed fluorescent oligonucleotide probes specific for the domain Bacteria and the alpha-, beta-, and gamma-subclasses of the class Proteobacteria. Lake snow aggregates were either collected in situ by SCUBA diving or in a sediment trap at 50 m or formed of natural lake water incubated in rolling cylinders under simulated in situ conditions. For the latter aggregates, the time course of the microbial colonization was also examined. The natural aggregates and those made in rolling cylinders were composed of the particulate organic material present in the lake and thus reflected the composition of the ambient plankton community. All types of lake snow aggregates examined were heavily colonized by microbial cells and harbored between 0.5 x 10(6) and > 2 x 10(6) cells aggregate -1. Between 55 and 100% of the microbial cells stained with 4', 6-diamidino-2-phenylindole (DAPI) could be visualized with the domain Bacteria-specific probe. In most samples, beta-subclass proteobacteria dominated the microbial community, constituting 27 to 42% of total cells as counted by DAPI staining, irrespective of the composition of the aggregates. During the time course experiments with the laboratory-made aggregates, the fraction of beta-subclass proteobacteria usually increased over time. Except for a few samples, alpha- and gamma-subclass proteobacteria were far less abundant than beta-subclass proteobacteria, constituting 11 to 25 and 9 to 33% of total cells, respectively. Therefore, we assume that a specific aggregate-adapted microbial community was established on the aggregates. Because the compositions of the microbial assemblages on natural and laboratory-made aggregates were similar, we conclude that aggregates made in rolling cylinders are good model system with which to examine the formation and microbial colonization of macroscopic organic aggregates.
