Risk of silicosis in cohorts of Chinese tin and tungsten miners, and pottery workers (I): an epidemiological study.

BACKGROUND Epidemiological evaluations of the risk of silicosis in relation to exposure to crystalline silica have raised the question of whether different types of silica dust exposures vary with respect to their ability to cause silicosis. The aim of this study is to compare the risk of silicosis among cohorts of silica dust-exposed Chinese tin miners, tungsten miners, and pottery workers and to assess whether gravimetric measurements of respirable silica dust sufficiently determine the risk of silicosis or whether other factors of exposure may play a significant role. METHODS Cohorts were selected from 20 Chinese mines and potteries. Inclusion criteria were starting employment after January 1, 1950 and being employed for at least 1 year during 1960-1974 in one of the selected workplaces. Radiological follow-up for silicosis onset was from January 1, 1950 through December 31, 1994. Silicosis was assessed according to the Chinese radiological criteria for diagnosis of pneumoconiosis (as suspect, Stage I, II, or III). Exposure-response relationships were estimated for silicosis of Stage I or higher. Silica dust exposure was estimated in terms of cumulative total dust exposure, calculated from a workplace, job title, and calendar year exposure matrix, and individual occupational histories. Cumulative total dust exposure was converted in two steps into cumulative respirable dust exposure and cumulative respirable silica dust exposure using conversion factors estimated from side-by-side measurements conducted in 1988-89. RESULTS The male cohorts included 4,028 tin miners, 14,427 tungsten miners, and 4,547 pottery workers who had similar onset of employment and duration of follow-up. For a given exposure level, the risk of silicosis was higher for the tin and tungsten than the pottery workers. CONCLUSION The observed differences in the risk of silicosis among the three cohorts suggest that silica dust characteristics, in addition to cumulative respirable silica dust exposure, may affect the risk of silicosis.
Progranulin increases phagocytosis by retinal pigment epithelial cells in culture

Retinal pigment epithelium (RPE) cells take part in retinal preservation, such as phagocytizing the shed photoreceptor outer segments (POS), every day. The incomplete phagocytic function accelerates RPE degeneration and formation of the toxic by‐product lipofuscin. Excessive lipofuscin accumulation is characteristic of various blinding diseases in the human eye. Progranulin is a cysteine‐rich protein that has multiple biological activities, and it has a high presence in the retina. Progranulin has been recognized to be involved in macrophage phagocytosis in the brain. The purpose of this study is to determine whether progranulin influences phagocytosis by RPE cells. All experiments were performed on primary human RPE (hRPE) cells in culture. pHrodo was used to label the isolated porcine POS, and quantification of pHrodo fluorescence was used to determine the degree of phagocytosis. Western blotting and immunohistochemistry of key proteins involved in phagocytosis were used to clarify the mechanism of progranulin. Progranulin increased RPE phagocytosis in hydrogen peroxide–treated and nontreated RPE cells. The phosphorylated form of Mer tyrosine kinase, which is important for POS internalization, was significantly increased in the progranulin‐exposed cells. This increase was attenuated by SU11274, an inhibitor of hepatic growth factor receptor. Under the oxidative stress condition, exposure to progranulin led to an approximately twofold increase in integrin alpha‐v, which is associated with the first step in recognition of POS by RPE cells. These results suggest that progranulin could be an effective stimulator for RPE phagocytosis and could repair RPE function. © 2017 Wiley Periodicals, Inc.
Metabolic syndrome in liver transplant recipients: Prevalence and association with major vascular events

Cardiac and cerebral vascular diseases are leading causes of morbidity and death in solid organ transplant recipients. Immunosuppressant drugs are associated with dyslipidemia, hypertension, and hyperglycemia, which along with obesity are the main features of metabolic syndrome. In the nontransplant population, metabolic syndrome is associated with increased risk for major vascular complications. We postulated that metabolic syndrome is common post–liver transplantation and plays a significant role leading to cardiac and cerebrovascular events. Our Multi‐Organ Transplant Program database was reviewed for all liver transplant recipients between January 1998 and June 2004 with follow‐up until December 2005. We adapted the 2001 National Cholesterol Education Program‐Adult Treatment Panel III Guidelines to define posttransplantation metabolic syndrome (PTMS) as the presence at least 3 of the following: 1) obesity (body mass index >30 kg/m2); 2) serum triglyceride level ≥1.7 mmol/L; 3) high density lipoprotein level <1 mmol/L in men and <1.3 mmol/L in women; 4) hypertension; and 5) fasting plasma glucose ≥5.6 mmol/L. A total of 118 patients were included. Among them, 69 patients (58%) had PTMS. The mean (± standard deviation) time from transplant was 59 ± 21 months (no significant difference in patients with or without metabolic syndrome). Overall, patients with metabolic syndrome had a significantly higher average age, posttransplantation body mass index, fasting glucose, high‐density lipoprotein levels, and serum triglycerides. There was no difference in creatinine, hemoglobin, or prednisone average dose between the 2 groups. There were 25 major vascular events affecting 21% of patients. There were significantly more vascular events in patients with metabolic syndrome posttransplantation than in those without (30% vs. 8%; P = 0.003) during the study period. In conclusion, the prevalence of metabolic syndrome post–liver transplant is significantly higher than that estimated in the general population. Metabolic syndrome appears to be associated with an increased risk of major vascular events in our liver transplant population. Liver Transpl 13:1109–1114, 2007. © 2007 AASLD.
Dermatoglyphic patterns and salivary pH in subjects with and without dental caries: A cross-sectional study

Background: Dermatoglyphic patterns, which are regularly used in judicial and legal investigations, can be valuable in the diagnosis of many diseases associated with genetic disorders. Dental caries although of infectious origin, may have a genetic predisposition. Hence, we evaluated the correlation between dental caries and dermatoglyphic patterns among subjects with and without dental caries and evaluated its association with environmental factors such as salivary pH. Materials and Methods: Totally, 76 female students within the age group of 18-23 years were clinically examined, and their decayed, missing, filled teeth (DMFT) score and oral hygiene index-simplified were recorded. Based on their DMFT score, they were divided into following three groups; group I (n = 16, DMFT score = 0), group II (n = 30, DMFT score <5), and group III (n = 30, DMFT score ≥5). Their fingerprint patterns and salivary pH were recorded and analyzed using descriptive statistics. Results: Dermatoglyphic pattern distribution in caries-free group showed more ulnar loops than high caries group (group III) while high caries group showed more whorl patterns. Presence of whorl with double loop, whorl within a loop was associated with high DMFT score. The total finger ridge count was lower in caries group. The mean salivary pH was higher in caries-free group than high caries group. Thus, we conclude that dermatoglyphic patterns may be potential diagnostic tool for detecting patients prone to develop dental caries.
Fibrinogen plasma concentration before delivery is not associated with postpartum haemorrhage: a prospective observational study.

BACKGROUND Low plasma fibrinogen concentration has been linked to postpartum haemorrhage. The primary aim of this study was to assess whether fibrinogen concentration at admission before labour is associated with severe postpartum haemorrhage. Secondary aims were to describe fibrinogen concentration before and after labour and to identify predictors for severe postpartum haemorrhage. METHODS 1951 healthy women were included in a prospective observational study. Fibrinogen concentration was determined at admission to the labour ward and in a subgroup of women (n=80) also after the placenta was delivered. Bleeding volume postpartum was estimated by weighing surgical sponges and pads and by measuring collected blood. Predictors for severe postpartum haemorrhage (>1000 ml) were identified with bivariate and multivariate regression analyses. RESULTS Mean fibrinogen concentration was 5.3 (SD 0.8) g litre(-) (1). Median estimated blood loss was 450 (range 70-4400) ml and 250 (12.8%) women bled >1000 ml. Fibrinogen concentration was not correlated with postpartum haemorrhage in the entire cohort (r(s)=0.003, P=0.90) or in any subgroup. Fibrinogen concentration was not associated with bleeding >1000 ml (odds ratio 1.01 (CI 95% 0.85-1.19), P=0.93) and did not differ significantly before and after delivery. Oxytocin stimulation, instrumental delivery, Caesarean section and exploration of uterus were identified as independent predictors of haemorrhage >1000 ml. CONCLUSIONS Fibrinogen plasma concentration at admission before labour does not predict severe postpartum haemorrhage in a general obstetric population. Fibrinogen concentration does not decrease significantly during normal labour. Excessive postpartum bleeding is mainly as a result of obstetric complications.
CONTRASTING THE UNDERLYING PATTERNS OF ACTIVE TRENDS IN MORPHOLOGIC EVOLUTION

Gastropod evolution during the early Paleozoic featured active trends (i.e., differential replacement of morphologies) for at least three shell characters. Selective sorting, either of individual organisms or of whole species, is an obvious mechanism for such active trends. Sorting of individuals should result in a disproportionate number of ancestor to descendant transitions being in the same direction as the trend, whereas sorting of species should result in species with particular morphologies producing more daughter species. Sorting of species can occur over long periods of time or it can be concentrated over a particular interval, such as an extinction event. Constraints on morphologic evolution also can drive trends, especially in cases where it is easier to produce a particular morphology than it is to change it. Finally, active trends can be artifacts of unrelated differential diversification within a clade (i.e., species hitchhiking), which might result from sorting of species based on phylogenetically associated characters or simply by chance. Unlike other active trends, trends attributable to species hitchhiking do not support hypotheses about selection or evolutionary constraints.
Commentary on the Gospel of Matthew

This excellent commentary on Matthew offers a unique interpretive approach that focuses on the socio-historical context of the Gospel and the nature of Matthew's exhortation to his first-century Christian audience. By merging a careful study of Matthew's Gospel in relation to the social context of the ancient Mediterranean world with a detailed look at what we know of first-century Jewish-Christian relations, Craig Keener uncovers significant insights into the Gospel not found in any other Matthew commentary.In addition, Keener's commentary is a useful discipleship manual for the church. His unique approach recaptures the full "shock effect" of Jesus' teachings in their original context and allows Matthew to make his point with greater narrative artistry. Keener also brings home the total impact of Matthew's message, including its clear portrait of Jesus and its call for discipleship, both to the Gospel's ancient readers and to believers today.
bic, a novel gene activated by proviral insertions in avian leukosis virus-induced lymphomas, is likely to function through its noncoding RNA

The bic locus is a common retroviral integration site in avian leukosis virus (ALV)-induced B-cell lymphomas originally identified by infection of chickens with ALVs of two different subgroups (Clurman and Hayward, Mol. Cell. Biol. 9:2657-2664, 1989). Based on its frequent association with c-myc activation and its preferential activation in metastatic tumors, the bic locus is thought to harbor a gene that can collaborate with c-myc in lymphomagenesis and presumably plays a role in late stages of tumor progression. In the present study, we have cloned and characterized two novel genes, bdw and bic, at the bic locus. bdw encoded a putative novel protein of 345 amino acids. However, its expression did not appear to be altered in tumor tissues, suggesting that it is not involved in oncogenesis. The bic gene consisted of two exons and was expressed as two spliced and alternatively polyadenylated transcripts at low levels in lymphoid/hematopoietic tissues. In tumors harboring bic integrations, proviruses drove bic gene expression by promoter insertion, resulting in high levels of expression of a chimeric RNA containing bic exon 2. Interestingly, bic lacked an extensive open reading frame, implying that it may function through its RNA. Computer analysis of RNA from small exon 2 of bic predicted extensive double-stranded structures, including a highly ordered RNA duplex between nucleotides 316 and 461. The possible role of bic in cell growth and differentiation is discussed in view of the emerging evidence that untranslated RNAs play a role in growth control.
The Saussure Effect in Lithuanian

The so-called "Saussure effect" describes the phenomenon of laryngeal loss in the following environments: *#HRo-and *-oRHC-. The fact that the effect is observed in several Indo-European branches suggests that it took place at the stage of Proto-Indo-European. In this paper, characteristic examples of the phenomenon in Lithuanian are presented, and an attempt is made to provide a consistent morphological explanation of the reason why no traces of the Saussure effect are observed in several seeming counterexamples where its operation is expected.
Moving a Carbohydrate Mimetic Peptide into the clinic

Tumor-Associated Carbohydrate Antigens (TACAs) are broad-spectrum targets for immunotherapy. Immunization with Carbohydrate Mimetic Peptides (CMPs) is a strategy to induce broad-spectrum TACA-reactive antibodies hypothesized to interfere with cellular pathways involved in tumor cell survival. A Phase I study was conducted with a first-in-man CMP referred to as P10s, conjugated to the Pan T cell carrier PADRE, along with MONTANIDE™ ISA 51 VG as adjuvant over a course of 5 immunizations. While designed as a safety and tolerability study, the potential for therapeutic impact was observed in a subject with metastatic lesions as evaluated before and after vaccine treatment. The subject received Vinorelbine and Trastuzumab (VT) for two months prior to study eligibility. PET scans showed partial response in the lungs and complete resolution of a previously enlarged subpectoral lymph node. Immunization with P10s vaccine resulted in responses to P10s, with serum and plasma antibodies reactive with and cytotoxic to human breast cancer cells in vitro, including the Trastuzumab-resistant HCC1954 cell line. However, the patient developed cystic masses in the brain parenchyma with no apparent evidence of metastases. The subject was switched to Docetaxel, Pertuzumab and Trastuzumab a year later, and her last PET scan showed a complete response in the lungs and lymph nodes. Incubation of cancer cells with a combination of vaccine-induced serum and docetaxel suggests that the induced antibodies sensitize tumor cells for more efficient killing upon administration of docetaxel. The data suggest that P10s-PADRE induces anti-tumor antibody response that in combination with chemotherapy can affect metastatic lesions in breast cancer patients.
Immunization against cerebral pathology in Plasmodium berghei-infected mice

The development of cerebral lesions in Plasmodium berghei-infected mice was dependent on the Strain of mice and the size of the infectious inoculum. In particular, C57B1/6J mice develop cerebral lesions when infected with low numbers of parasitized erythrocytes. By increasing the number of parasites in the infectious inoculum, the percentage of animals that develop cerebral malaria is decreased. Varying degrees of protection against the development of cerebral malaria can be obtained by several methods of immunization. (1) Injection of mice with large numbers of disrupted parasitized erythrocytes 1 or 2 weeks before the challenge infection (protection up to 70%). (2) A 2-day immunizing infection given 9 or 14 days before the challenge infection (protection up to 85%). (3) Injection of mice with plasmodial exoantigen preparations 1 week before the challenge infection (variable protection-rate, up to 100%). In all mice protected against cerebral malaria, parasitaemia is not affected by the immunizing treatment, indicating that protective mechanisms against cerebral malaria and parasitaemia are independent.
Is It All Relative?

We argue that various types of evaluative social judgments about the self or others (e.g., employee job performance ratings, self-reported attitudes, ratings of others' traits) may be obtained more accurately using comparative ratings rather than absolute ratings. Comparative ratings involve relative judgments of a target in comparison with other individuals or groups, whereas absolute ratings involve judgments of a target on scales that do not explicitly reference other people. In industrial–organizational, social, and personality psychology research that has compared the validity of comparative and absolute ratings, we have found evidence of more valid measurement as a result of comparative judgmental ratings, despite the nearly exclusive reliance on absolute judgmental ratings in these areas. We offer a social cognitive and evolutionary explanation in support of the hypothesis that humans may often be able to make more accurate ratings using comparative measures. We also recommend an agenda for greater exploitation and understanding of relative judgments in psychological research and practice.
Impact of geometry-dependent parasitic capacitances on the performance of CNFET circuits

Intrinsic carbon-nanotube field-effect transistors (CNFETs) have been shown to have superior performance over silicon transistors. In this letter, we provide an insight how the parasitic fringe capacitance in state-of-the-art CNFET geometries impacts the overall performance of CNFET circuits. We show that unless the device (gate) width can be significantly reduced, the effective gate capacitance of CNFET will be strongly dominated by the parasitic fringe capacitances, and the superior performance of intrinsic CNFET over silicon MOSFET cannot be achieved in circuit.
Protective effects and anti-apoptotic role of nerve growth factor on spinal cord neurons in sciatic nerve-injured rats

Abstract Objectives: The purpose of this study is to demonstrate a dependence of spinal cord motoneurons on the communication with their targets, sciatic nerves, and investigate whether the effects of nerve growth factor (NGF) on the spinal cord neuron apoptosis and surviving through the regulation of nuclear factor-kappa B (NF-kappaB) in Schwann cells (SCs) in sciatic nerve injured rats. Methods: Ninety healthy adult Sprague–Dawley rats were divided randomly into normal control group, crushing group, and NGF-intervened group. When sciatic nerve crushed 1, 3, 7, 14, and 21 days, the expression of NF-kappaB in SCs and the apoptosis regulator Bcl-2 and Caspase-3 in spinal cord were examined by immunohistochemistry staining, Western blot analysis, and immunofluorescence double-labeling method, the motor neuron apoptosis were investigated by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL), and the surviving neurons were tested by toluidine blue (Nissl) staining, respectively. All the data were further analyzed with SPSS10·0 application software. Results: The level of the expression of NF-kappaB in crushing group enhanced at 1 day after crushing, reached peak at 3 days, and reduced at least until 21 days, which was markedly higher than that in the normal control group. The expression of NF-kappaB in NGF-intervened group showed the same changes, reached peak at 7 days, and reduced until 21 days. However, when compared with crushing group, the expression of NF-kappaB in NGF-intervened group was down-regulated significantly until 3 days after injury, and up-regulated obviously with time going on. The same trend was observed in the time course on motor neuron apoptosis in crushing group and NGF-intervened group after sciatic nerves injury, while the reversing change was found in the surviving neurons. Moreover, the kinetics of Bcl-2 expression in spinal cord was consistent with that of NF-kappaB, while reversing with that of Caspase-3. Conclusion: The findings revealed that NGF may play a pivotal role of anti-apoptosis in spinal cord neurons through retrograde transport of NF-kappaB in SCs following sciatic nerve injury in rats.
Apolipoprotein ɛ4 is Associated with Dementia and Cognitive Impairment Predominantly Due to Alzheimer's Disease and Not with Vascular Cognitive Impairment: A Singapore-Based Cohort.

BACKGROUND AND OBJECTIVE While the association for apolipoprotein ɛ4 allele (APOE4) with Alzheimer's disease (AD) has been consistently confirmed, the association with vascular cognitive impairment (VCI) is unclear. We therefore explored the relationship of APOE with both AD and cerebrovascular disease (CeVD) by examining the prevalence of APOE4 in AD, AD with CeVD and vascular dementia (VaD), as well as in cognitive impairment no dementia (CIND) with and without CeVD. METHODS We performed a case-control study with subjects recruited from memory clinics and the community. All subjects underwent standardized brain neuroimaging, clinical and neuropsychological assessments, following which they were classified using research criteria. RESULTS A total of 411 subjects; 92 controls with no cognitive impairment (NCI), 77 CIND without CeVD, 87 CIND with CeVD, 55 AD without CeVD, 68 AD with CeVD, and 32 VaD patients were recruited. Compared to NCI (16.3%), the prevalence of APOE4 carriers was significantly higher only in CIND (37.7%) and AD in the absence of CeVD (45.5%), but not in the three subgroups of VCI, namely CIND with CeVD (20.7%), AD with CeVD (27.9%) and VaD (25.0%). Logistic regression analyses also showed that APOE4 carriers were more likely to have CIND without CeVD (Odds Ratio [OR]: 3.34; 95% Confidence Interval [CI]: 1.59-7.03) and AD without CeVD (OR: 7.21; 95% CI: 2.74-18.98), but no such association was observed in the VCI subgroups. CONCLUSION APOE4 is significantly associated with dementia and CIND due to AD pathology, but not with VCI.
Amelioration of doxorubicin induced cardio-and hepato-toxicity by carotenoids.

AIM OF STUDY The aim of this study is to explore the ability of the carotenoids (CARs) to offer protection against acute cardiotoxicity and hepatotoxicity induced by doxorubicin (DOX) (25 mg/kg) in tumor bearing Swiss albino mice. MATERIALS AND METHODS Tumor bearing Swiss albino mice administered with DOX (25 mg/kg, i.p) and two doses of CARs (50 and 100 μg/kg). 24 h after administration of the drugs, histopathological evaluation of tumor, liver and heart tissues carried out. Furthermore, various antioxidant parameters in these tissues were investigated. Serum marker enzymes for tissue injury were examined. RESULTS Administration of CARs prevented the depletion of antioxidants in the heart and liver, thereby protecting the tissue damage and release of marker enzymes. However, similar antioxidant depletion was not observed in the tumor tissue. CARs prevented DOX induced variation in tissue architecture in heart and liver tissues. However, CARs did not influence DOX induced alterations in the tumor. CONCLUSION Administration of CARs could prevent DOX induced acute toxicity to heart and liver.
