For investigate the role of ultrasound and platelets count as an important marker for the diagnosis and prognosis of dengue patients

Background: Dengue is although self limiting viral disease but if severe complications take place than it becomes lethal. Plasma leakage is main pathology which results in fluid deposits in various organs. This plasma leakage is related to platelet count. Most important thing in treating dengue patient is to know the complications at the earliest. And ultrasound is the most sensitive and easily approachable, cost effective investigation for detecting the complications.Methods: This cross-sectional observational pilot study was carried out in the department of radiodiagnosis, pandit bhagwat dayal Sharma institute of medical sciences, Rohtak. One hundred and two patients with serologically confirmed dengue fever were included in this study. Ultrasound examinations were carried out by ultrasound machine with 5-13 MHZ probe by radiologists. Abdomen and thorax scanning were done thoroughly. Important findings like Gall bladder thickening hepatomegaly, splenomegaly, free fluid which are pathological markers for dengue were specially seen. Then these findings are relate to the age group and platelet count.Results: By applying chi square test we found that there is statistically difference in number of patients in age group 16-30 yrs having gall bladder wall thickening, hepatomegaly, free fluid, splenomegaly and pleural effusion as compared to other age groups (p<0.05) an also in patients having less than 20,000 platelets, only gall bladder thickening, ascites and hepatomegaly were statistically more significant as compared to other groups having more number of platelets (p<0.05).Conclusions: So, ultrasound and platelet count are important markers for diagnosis and prognosis of dengue patients. Ultrasound and Platelets count are important markers for the diagnosis as well as prognosis of dengue patients

Ascorbate-mediated enhancement of reactive oxygen species generation from polymorphonuclear leukocytes: modulatory effect of nitric oxide

Recent studies from our laboratory have demonstrated that ascorbate potentiated enzymatic synthesis of nitric oxide (NO) from polymorphonuclear leukocytes (PMNs). NO is known to modulate various function of PMNs such as chemotaxis, adherence, aggregation, and generation of reactive oxygen species (ROS). The role of ascorbate in the PMN phagocytosis, ROS generation, and apoptosis was thus evaluated in the present study. Ascorbate and its oxidized and cell-permeable analog, dehydroascorbate (DHA), did not affect the phagocytosis but enhanced ROS generation and apoptosis following treatment with Escherichia coli or arachidonic acid. A detailed investigation on the DHA-mediated response indicated that inhibitors of DHA uptake, reduced nicotinamide adenine dinucleotide phosphate oxidase, NO synthase, or ROS scavengers attenuated ROS generation. In DHA-treated cells, enhanced generation of peroxynitrite was also observed; thus, ascorbate-mediated ROS and reactive nitrogen species generation might mediate cytotoxicity toward the ingested microbes and subsequently, augmented PMN apoptosis. Results of the present study have helped in delineating the role of ascorbate in the modulation of NO-mediated ROS generation from PMNs

THE PATHOGENESIS AND INDIGENOUS MANAGEMENT OF ASRGDARA W.S.R TO MENORRHAGIA

Menorrhagia is a very common complaint among females in recent years. The World Health Organization reports that 18 million women aged 30-55 years perceive their menstrual bleeding to be exorbitant. Reports show that only 10% of these women experience blood loss severe enough to cause anaemia or be clinically defined as menorrhagia.Asrgdara means heavy vaginal bleeding during or before or after menstrual period. Though the menorrhagia is not directly described in any textbook of Ayurveda but it is quite similar to Asrgdara having uterine bleeding other than menstrual bleeding among other causes. Menorrhagia is not new for Ayurveda which is described under the heading of the Asrgdara. The main clinical feature of both menorrhagia and Asrgdara is uterine bleeding along with its other complications. The main types of Asrgdara are Vataja, Pittaj, Kaphaj, and Sannipataj Trividhpariksha also helps to diagnose the disease by means of Darshan (inspection), Sparshan (palpitation) and Prashan (questioning). There are so many generic and patent drug available in Ayurveda like Raktapradarharyog, Ashokaristha, Pradarantakras, Pradrariras may helpful to stop the bleeding and also able to cure the complications of Asrgdara..Thus Ayurvedic treatment may have strong ability of breaking down the pathogenesis of Asrgdara and its management also

Single nucleotide polymorphism in the genes of mce1 and mce4 operons of Mycobacterium tuberculosis: analysis of clinical isolates and standard reference strains

<p>Abstract</p> <p>Background</p> <p>The presence of four mammalian cell entry (<it>mce</it>) operons in <it>Mycobacterium tuberculosis </it>suggests the essentiality of the functions of the genes in these operons. The differential expression of the four <it>mce </it>operons in different phases of <it>in vitro </it>growth and in infected animals reported earlier from our laboratory further justifies the apparent redundancy for these genes in the genome.</p> <p>Here we investigate the extent of polymorphism in eight genes in the <it>mce1 </it>and <it>mce4 </it>operons of <it>M. tuberculosis </it>from four standard reference strains (H37Rv, H37Ra, LVS (Low Virulent Strain) and BCG) and 112 clinical isolates varying in their drug susceptibility profile, analysed by direct sequencing and Sequenom MassARRAY platform.</p> <p>Results</p> <p>We discovered 20 single nucleotide polymorphisms (SNPs) in the two operons. The comparative analysis of the genes of <it>mce1 </it>and <it>mce4 </it>operons revealed that <it>yrbE1A </it>[<it>Rv0167</it>] was most polymorphic in <it>mce1 </it>operon while <it>yrbE4A </it>[<it>Rv3501c</it>] and <it>lprN </it>[<it>Rv3495c</it>] had the highest number of SNPs in the <it>mce4 </it>operon. Of 20 SNPs, 12 were found to be nonsynonymous and were further analysed for their pathological relevance to <it>M. tuberculosis </it>using web servers PolyPhen and PMut, which predicted five deleterious nonsynonymous SNPs. A mutation from proline to serine at position 359 of the native Mce1A protein was most deleterious as predicted by both PolyPhen and PMut servers. Energy minimization of the structure of native Mce1A protein and mutated protein was performed using InsightII. The mutated Mce1A protein showed structural changes that could account for the effects of this mutation.</p> <p>Conclusions</p> <p>Our results show that SNPs in the coding sequences of <it>mce1 </it>and <it>mce4 </it>operons in clinical isolates can be significantly high. Moreover, <it>mce4 </it>operon is significantly more polymorphic than <it>mce1 </it>operon (p < 0.001). However, the frequency of nonsynonymous substitutions is higher in <it>mce1 </it>operon and synonymous substitutions are more in <it>mce4 </it>operon. <it>In silico </it>modeling predict that nonsynonymous SNP at <it>mce1A </it>[<it>Rv0169</it>], a virulence gene could play a pivotal role in causing functional changes in <it>M. tuberculosis </it>that may reflect upon the biology of the bacteria.</p

Effect of pioglitazone treatment in a patient with secondary multiple sclerosis

BACKGROUND: Ligands of the peroxisome proliferator-activated receptor-gamma (PPARγ) induce apoptosis in activated T-lymphocytes and exert anti-inflammatory effects in glial cells. Preclinical studies have shown that the thiazolidinedione pioglitazone, an FDA-approved PPARγ agonist used to treat type 2 diabetes, delays the onset and reduces the severity of clinical symptoms in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis (MS). We therefore tested the safety and therapeutic potential of oral pioglitazone in a patient with secondary MS. CASE PRESENTATION: The rationale and risks of taking pioglitazone were carefully explained to the patient, consent was obtained, and treatment was initiated at 15 mg per day p.o. and then increased by 15 mg biweekly to 45 mg per day p.o. for the duration of the treatment. Safety was assessed by measurements of metabolic profiles, blood pressure, and edema; effects on clinical symptoms were assessed by measurement of cognition, motor function and strength, and MRI. Within 4 weeks the patient exhibited increased appetite, cognition and attention span. After 12 months treatment, body weight increased from 27.3 to 35.9 kg (32%) and maintained throughout the duration of the study. Upper extremity strength and coordination improved, and increased fine coordination was noted unilaterally after 8 months and bilaterally after 15 months. After 8 months therapy, the patient demonstrated improvement in orientation, short-term memory, and attention span. MRIs carried out after 10 and 18 months of treatment showed no perceptible change in overall brain atrophy, extent of demyelination, or in Gd-enhancement. After 3.0 years on pioglitazone, the patient continues to be clinically stable, with no adverse events. CONCLUSIONS: In a patient with secondary progressive MS, daily treatment with 45 mg p.o. pioglitazone for 3 years induced apparent clinical improvement without adverse events. Pioglitazone should therefore be considered for further testing of therapeutic potential in MS patients

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe
