Neurotoxicity Research | Year: 2011

Aluminum is neurotoxic both in animals and human beings primarily because of its interference with biological enzymes in key mechanisms of metabolic pathways. Mitochondrial dysfunction is one such mechanism that has been implicated in the pathogenesis of neurodegenerative diseases like Alzheimer's disease. Aluminum toxicity is very closely related to Alzheimer's disease. We evaluated the potentials of curcumin, a known cytoprotectant, against neurotoxic consequences of aluminum that acts through a wide range of mechanisms. Curcumin has been reported to be an antioxidant, and it is this property that is widely held to be responsible for its protective effects in tissue. Aluminum was administered by oral gavage at a dose level of 100 mg/kg body wt/day for a period of 8 weeks. Curcumin was administered in conjunction with aluminum at a dose of 50 mg/kg of body wt i.p. for a period of 8 weeks on alternate days. The effects of different treatments were studied on oxidative phosphorylation and reduced glutathione of different regions of rat brain. The study indicates reduced activity of NADH dehydrogenase (complex I), succinic dehydrogenase (complex II), and cytochrome oxidize (Complex IV) in all the three regions of rat brain, i.e., cerebral cortex, mid brain, and cerebellum. Curcumin supplementation to aluminum-treated rats was able to normalize significantly the activities of all the three mitochondrial complexes as well as reduced glutathione content in all the three regions of brain which were altered following aluminum treatment. We conclude that curcumin, by attenuating oxidative stress, as evident by hypoxia in histological observations and mitochondrial dysfunction holds a promise as an agent that can potentially reduce aluminum-induced adverse effects in brain. © 2011 Springer Science+Business Media, LLC.

OBJECTIVES: Chronic infections can cause serious complications and create morbidity and mortality for affected patients during immunosuppressive therapy in the posttransplant period. Here, we studied the microbiologic screening results of patients before living-donor liver transplant.MATERIALS AND METHODS: The microbiologic screening results of 25 patients during 2015 at National Scientific Research Center (Astana, Kazakhstan) before livingdonor liver transplant were prospectively analyzed. Sputum samples, swabs from throat and nose, and urine samples were collected for quantitative microbiologic examination. Identification of isolates and antibiotic susceptibility testing were performed using the Vitek 2 automated system (bioMérieux, Marcy l'Etoile, France).RESULTS: Of the patients, 16 (64%) were female and the average age was 46.8 ± 2.2 years. Of 97 clinical samples collected, 80 samples (82.4%) showed bacterial growth. A total of 88 isolates to 15 different species was isolated. The greatest number of bacteria was isolated from throat swabs (35.2%). Of 88 isolates, 70 isolates (79.5%) were gram-positive, with α-hemolysis streptococci being the major isolate (39.7%). Coagulase-negative staphylococci were found in 13.6% of isolates, Staphylococcus aureus in 11.3%, and both Klebsiella pneumoniae and Streptococcus pneumoniae in 10.2%. Results of antibiotic susceptibility testing showed that the resistance rate of Staphylococcus aureus to oxacillin was 10%. About 87.5% of isolates of Klebsiella pneumoniae were resistant to inhibitor-protected penicillin, 85.7% to quinolones, and more than 60% to cephalosporins and aminoglycosides groups of antibiotics.CONCLUSIONS: Microbiologic monitoring of recipients before living-donor liver transplant showed higher prevalence of opportunistic pathogens. These results suggest establishing quality preoperative preparations with a view to possible improvements in the health status of intended recipients and elimination of factors that could adversely affect the transplant and cause complications during the postoperative period.

Endocrine Pathology | Year: 2014

Parathyroid carcinoma has always been difficult to diagnose pathologically. In fact, most parathyroid tumors which are classified as carcinoma do not recur after excision, and most parathyroid tumors which actually metastasize or recur repeatedly in the neck are not recognized as malignant at first presentation. In 2002, germline HRPT2 (also known as CDC73) mutation was reported as the cause of hyperparathyroidism-jaw tumor (HPT-JT) syndrome, an autosomal dominant hereditary tumor syndrome associated with a lifetime risk of parathyroid carcinoma approaching 15 %. Subsequently, bi-allelic inactivation or mutation of HRPT2 has been reported in the majority of parathyroid carcinomas that actually behave in a malignant manner but very rarely in sporadic benign parathyroid disease. Furthermore, germline testing for HRPT2 mutation in patients presenting with parathyroid carcinoma often identifies occult HPT-JT syndrome even in the absence of a family history or other syndromic manifestations. HRPT2 mutation testing is not readily available, and loss of expression of parafibromin (the protein encoded by HRPT2) as determined by immunohistochemistry has been used as a surrogate marker of HRPT2 mutation. Immunohistochemistry for parafibromin can be technically difficult and has been deployed by different investigators with variable enthusiasm and success. However, proponents have found immunohistochemistry for parafibromin useful to definitively confirm a pathological diagnosis of parathyroid carcinoma, predict a worse outcome in definite parathyroid carcinomas, triage formal genetic testing for HPT-JT syndrome, and predict the outcome of histologically atypical parathyroid adenomas. © 2014 Springer Science+Business Media.

Recently, the R-spondin (RSPO) family of proteins has emerged as important regulators of WNT signaling. Considering the wide spectrum of WNT signaling functions in normal biological processes and disease conditions, there has been a significantly growing interest in understanding the functional roles of RSPOs in multiple biological processes and determining the molecular mechanisms by which RSPOs regulate the WNT signaling pathway. Recent advances in the RSPO research field revealed some of the in vivo functions of RSPOs and provided new information regarding the mechanistic roles of RSPO activity in regulation of WNT signaling. Herein, we review recent progress in RSPO research with an emphasis on signaling mechanisms and biological functions. © 2012 Elsevier Ltd. All rights reserved.

This paper traces the evolution of measures and parameters for the evaluation of science and scientific journals from the first attempts during the early part of the last century to the development of the most popular, current and widely used metrics viz., citations, impact factor (IF) etc. The identification of measures of evaluation in science and scientific reporting paralled the post-war increase in funding in the United States of America. Biomedical and medical sciences continue to garner a major share, estimated to be almost two-thirds of total research and development funding of over US$ 350 billion. There has been a concomitant growth in the publications in learned journals. About 1.4 million papers are published every year in an estimated 20,000 journals. In India there are an estimated 100 journals in medical sciences. With a steady increase of about 10% every year, the competition for grants, awards, rewards etc., is fierce. This unrelenting increase in number of scientists and the resultant competition, the limitation of peer review was felt. A search was on for new quantifiable measures for informed decision making for funding, awards, rewards, etc. Now virtually all major decisions all over the world are based on some data linked to publications and/or citations. The concept of citations as tool for 'evaluating' science was first proposed by Eugene Garfield in 1955. The availability of Science Citation Index (SCI), Journal Citation Reports (JCR), Web of Science etc. and the relative ease with which they could be used (and abused) has spawned an entirely new area bibliometrics/scientometrics. As only a limited number of journals could be included in the Thomson Reuters (TR) databases (currently numbering about 10500), analyses based on such a limited dataset (also selected in a non-transparent way by the TR) has been widely and severely criticized by both the developed and developing countries. Yet, studies have shown that citation-based data and indicators (warts and all) could still be put to productive use for purposes of evaluation (as scientists just love numbers). There were simultaneous efforts to find alternative indicators using the TR databases, and through other innovative methods. Some of these include Google Scholar, PageRank, H-index, Y-factor, Faculty of 1000, Eigen Factor etc. The advantages and limitations of these indices are discussed. There is a need for a more critical look at these parameters from the Indian perspective to compute/ device/adapt these measures to suit our needs. There are 205 journals under the category Physiology and 201 in the Pharmacology category listed in the JCR. There are four major Indian journals under the category of Physiology and Pharmacology and none of them are listed in the TR databases reflecting the limitation of these databases. Eventually, and in the long run, the quality of our journals needs to be improved as the current era of globalization and web-access provides both a challenge and an opportunity for the science and scientific journals published from India to get increased global visibility.
