Silicosis, modern huge fibrosis as well as silico-tuberculosis among personnel with occupational contact with this mineral dusts inside sandstone mines regarding Rajasthan state: An urgent dependence on commencing countrywide silicosis control plan inside Asia.
The presence of mucin in the artificial lubricant led to the lowest wear coefficients. The main wear mechanism was abrasion, independently of the used lubricant. Adhesive wear was observed for the systems without mucin. Tribocorrosion activity and wear coefficient were lower in the presence of mucin. None of the studied artificial lubricants mimicked the effect of human saliva (HS) on the tribological behavior of the studied pair since this lubricant led to the lowest friction coefficient and highest corrosion activity.The problems of resistance and side effects associated with cisplatin and other chemotherapeutic drugs have boosted research aimed at finding new compounds with improved properties. The use of platinum(IV) prodrugs is one alternative, although there is some controversy regarding the predictive ability of the peak reduction potentials. In the work described here a series of fourteen chloride Pt(II) and Pt(IV) compounds was synthesised and fully characterised. The compounds contain different bidentate arylazole heterocyclic ligands. Their cytotoxic properties against human lung carcinoma (A549), human breast carcinoma (MCF7) and human colon carcinoma (HCT116 and HT29) cell lines were studied. A clear relationship between the type of ligand and the anti-proliferative properties was found, with the best results obtained for the Pt(II) compound that contains an aniline fragment, (13), thus evidencing a positive effect of the NH2 group. Stability and aquation studies in DMSO, DMF and DMSO/water mixtures were carried out on the active complexes and an in-depth analysis of the two aquation processes, including DFT analysis, of 13 was undertaken. It was verified that DNA was the target and that cell death occurred by apoptosis in the case of 13. Furthermore, the cytotoxic derivatives did not exhibit haemolytic activity. The reduction of the Pt(IV) compounds whose Pt(II) congeners were active was studied by several techniques. It was concluded that the peak reduction potential was not useful to predict the ability for reduction. However, a correlation between the cytotoxic activity and the standard reduction potential was found.Measurement of acute phase proteins (APPs) as biomarkers in canine medicine is in increasing demand. In the present study, the development and validation of two ELISA methods for the quantification of canine inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4) and haptoglobin (Hp) are shown. The adequate imprecision and accuracy and wide analytical range make the developed methods appropriate to quantify ITIH4 and Hp in serum samples. Chloroquine order The inter- and intra-assay CVs were lower than 10 %, and the assays maintained linearity under dilution and showed analytical equivalence with the method of radial immunodiffusion. The measurement of CRP, Hp and ITIH4 in sera from bitches affected by pyometra allowed us to determine that ITIH4 behaves as a moderate APP in dogs. The group of bitches affected by pyometra showed very high levels of CRP (147 ± 91 mg/L), corresponding to a strong inflammatory process, which resulted in a moderate increase in the concentrations of Hp (7 times) and ITIH4 (3 times) compared to the control group.Racial and ethnic minorities, including Blacks/African-Americans and Hispanics/Latinos,indicate lower tolerance to psychological distress (DT) and secular hope yet endorse more religious and spiritual hope than their non-Hispanic White (NHW) counterparts. Whether racial-ethnic minorities derive greater benefit from non-secular hope on the tolerance of psychological distress remains unclear. Self-reported endorsement of religious/spiritual (R/S) hope, secular hope, DT, and a number of other psychosocial, R/S and sociodemographic variables were analyzed from a nationwide survey of persons aged over 18 years (N = 2875) identifying as Black (14.2%), Hispanic (15.4%), or NHW (67.3%) using multiple regression. Overall, higher levels of both R/S and secular hope predicted greater DT. In turn, greater DT was associated with lower psychosomatic distress. Compared to NHW, the ethnic-minority groups reported lower overall levels of DT. An interaction for race-ethnicity further revealed that compared to distress intolerant NHW, Blacks/African-Americans at lower levels of DT report higher R/S and secular hope. Hispanics/Latinos were also higher on R/S and secular hope, but endorsed lower hope at higher levels of DT than the reference group. Although hope is considered a more passive form of coping, it is more frequently endorsed in marginalized ethnic-minority groups. However, compared to NHW, differences do exist in the extent to which R/S hope mitigates DT in Blacks/African-Americans compared to Hispanics/Latinos.
The journal received a request to retract a paper reporting the results of a triple-blind randomized placebo-controlled trial. The present and immmediate past editors expand on the journal's decision not to retract this paper in spite of undisputable evidence of scientific misconduct on behalf of one of the investigators.

The editors present an ethical reflection on the request to retract this randomized clinical trial with consideration of relevant guidelines from the Committee on Publication Ethics (COPE) and the International Committee of Medical Journal Editors (ICMJE) applied to the unique contextual issues of this case.

In this case, scientific misconduct by a blinded provider of a homeopathy intervention attempted to undermine the study blind. As part of the study, the integrity of the study blind was assessed. Neither participants nor homeopaths were able to identify whether the participant was assigned to homeopathic medicine or placebo. Central to the decision not to retract the paper was the fact that the rigorous scientific design provided evidence that the outcome of the study was not affected by the misconduct. The misconduct itself was thought to be insufficient reason to retract the paper.

Retracting a paper of which the outcome is still valid was in itself considered unethical, as it takes away the opportunity to benefit from its results, rendering the whole study useless. In such cases, scientific misconduct is better handled through other professional channels.
