Role of Dashamoola Shatphala Ghrita in the management of Vataja Kasa w.s.r. to Tropical Pulmonary Eosinophilia - A Clinical Study

Kasa is a very common disease of Pranavaha Srotas. When Adhoga Gati of Vata is obstructed by Dusta Doshas, it attains the Urdhva Gati and takes Sthanasamshraya in Urah Pradesha and producing to Kasa. Vataja Kasa is one among the types of Kasa, where Shuska Kasa is prominent symptom. Vataja Kasa is taken as special reference to Tropical Pulmonary Eosinophilia because of similarities of signs and symptoms. India being one of the tropical country, the prevalence of Vataja Kasa vis-à-vis Tropical Pulmonary Eosinophilia is remarkably high. The syndrome is particularly endemic in India, Sri Lanka, South East Asia and Africa and has been reported from filarial epidemic areas worldwide. In this present study an attempt is made to evaluate the efficacy of Dashamoola Shatphala Ghrita in Vataja Kasa vis-à-vis Tropical Pulmonary Eosinophilia. A minimum of 30 subjects who fulfilled the diagnostic & inclusion criteria was subjected to the intervention. The overall results in the study revealed statistically highly significant result

Evaluations of Thinning Algorithms for Preprocessing of Handwritten Characters

Thinning algorithms have played an important role in preprocessing phase which decides the success of recognition in the OCR system. This paper report on the performance of 11 thinning algorithms from the perspective of character recognition where different aspects of the performance of each algorithm like computing time, deviation from perfect 8-connectedness, and number of possible noise spurs present in the skeletons are considered

N 6 -Formyllysine as a Biomarker of Formaldehyde Exposure: Formation and Loss of N 6 -Formyllysine in Nasal Epithelium in Long-Term, Low-Dose Inhalation Studies in Rats

Exposure to both endogenous and exogenous formaldehyde has been established to be carcinogenic, likely by virtue of forming nucleic acid and proteins adducts such as N6-formyllysine. To better assess N6-formyllysine as a biomarker of formaldehyde exposure, we studied accumulation of N6-formyllysine adducts in tissues of rats exposed by inhalation to 2 ppm [13C2H2]-formaldehyde for 7, 14, 21, and 28 days (6 h/day) and investigated adduct loss over a 7-day postexposure period using liquid chromatography-coupled tandem mass spectrometry. Our results showed formation of exogenous adducts in nasal epithelium and to some extent in trachea but not in distant tissues of lung, bone marrow, or white blood cells, with a 2-fold increase over endogenous N6-formyllysine over a 3-week exposure period. Postexposure analyses indicated a biexponential decay of N6-formyllysine in proteins extracted from different cellular compartments, with half-lives of ∼25 and ∼182 h for the fast and slow phases, respectively, in cytoplasmic proteins. These results parallel the behavior of DNA adducts and DNA-protein cross-links, with protein adducts cleared faster than DNA-protein cross-links, and point to the potential utility of N6-formyllysine protein adducts as biomarkers of formaldehyde

Measurement of Oxygenated Polycyclic Aromatic Hydrocarbons Associated with a Size-Segregated Urban Aerosol

Size-segregated atmospheric particles were collected in Boston, MA, using a micro-orifice impactor. The samples were analyzed for oxygenated polycyclic aromatic hydrocarbons (OPAH) using gas chromatography/mass spectrometry. Seven PAH ketones (1-acenaphthenone, 9-fluorenone, 11H-benzo[a]fluoren-11-one, 7H-benzo[c]fluoren-7-one, 11H-benzo[b]fluoren-11-one, benzanthrone, and 6H-benzo[cd]pyrene-6-one), four PAH diones (1,4-naphthoquinone, phenanthrenequinone, 5,12-naphthacenequinone, and benzo[a]pyrene-6,12-dione), and one PAH dicarboxylic acid anhydride (naphthalic anhydride) were identified. Seven additional compounds with mass spectra typical of OPAH were tentatively identified. OPAH were generally distributed among aerosol size fractions based on molecular weight. Compounds with molecular weights between 168 and 208 were ap proximately evenly distributed between the fine (aerodynamic diameter, D_p, 2 μm) particles. OPAH with molecular weights of 248 and greater were associated primarily with the fine aerosol fraction. Most OPAH were distributed with particle size in a broad, unimodal hump similar to the the distributions observed for PAH in the same samples. These results suggest that OPAH are initially associated with fine particles after formation by either combustion or gas phase photooxidation and then partition to larger particles by vaporization and sorption. Two OPAH were distributed in bimodal distributions with peaks at D_p ≈ 2 μm and D_p ≈ 2 μm. These bimodal distributions may be indicative of sorption behavior different from PAH and other OPAH

Measurement of C_(24)H_(14) Polycyclic Aromatic Hydrocarbons Associated with a Size-Segregated Urban Aerosol

Six-ring C_(24)H_(14) (MW 302) polycyclic aromatic hydrocarbons (PAH), some of which are potent mutagens, are present in urban aerosols. Size-segregated atmospheric aerosol samples from Boston, MA, were analyzed for C_(24)H_(14) PAH by gas chromatography/mass spectrometry. Eleven peaks were found with mass to charge ratios of 302; of these, eight were identified using authentic standards. Five of the peaks were quantified. For each of these five, the distributions with respect to particle size were bimodal with the majority of the mass associated with accumulation mode particles (0.3−1.0 μm) and a smaller fraction of the mass associated with ultrafine mode particles (0.09−0.14 μm). These distribu tions are similar to those observed for PAH of molecular weight 252−278 in the same sample but different from those of benzo[ghi]perylene (MW 276) and coronene (MW 300), which were associated to a greater degree with ultrafine particles. The data suggest that C_(24)H_(14) PAH repartition to larger particles by vaporization and sorption more rapidly than do benzo[ghi]perylene and coronene. The total concentration of C_(24)H_(14) PAH (1.5 ng/m^3) was comparable to that of benzo[a]pyrene in the same sample. Because of their mutagenicities, C_(24)H_(14) PAH may make a contribution to the genotoxicity of urban aerosols comparable to that of benzo[a]pyrene

GLIS1 regulates trabecular meshwork function and intraocular pressure and is associated with glaucoma in humans.

Chronically elevated intraocular pressure (IOP) is the major risk factor of primary open-angle glaucoma, a leading cause of blindness. Dysfunction of the trabecular meshwork (TM), which controls the outflow of aqueous humor (AqH) from the anterior chamber, is the major cause of elevated IOP. Here, we demonstrate that mice deficient in the Krüppel-like zinc finger transcriptional factor GLI-similar-1 (GLIS1) develop chronically elevated IOP. Magnetic resonance imaging and histopathological analysis reveal that deficiency in GLIS1 expression induces progressive degeneration of the TM, leading to inefficient AqH drainage from the anterior chamber and elevated IOP. Transcriptome and cistrome analyses identified several glaucoma- and extracellular matrix-associated genes as direct transcriptional targets of GLIS1. We also identified a significant association between GLIS1 variant rs941125 and glaucoma in humans (P = 4.73 × 1

Isoniazid hair concentrations in children with tuberculosis: a proof of concept study

Assessing treatment adherence and quantifying tuberculosis drug exposure among children is challenging. We undertook a “proof of concept” study to assess the drug concentrations of isoniazid in hair as a therapeutic drug monitoring tool. Children <12 years of age initiated on thrice-weekly treatment including isoniazid (10 mg/kg) for newly diagnosed tuberculosis were enrolled. Isoniazid concentrations in hair were measured using liquid chromatography-tandem mass spectrometry at 1, 2, 4 and 6 months after tuberculosis treatment initiation. We found that isoniazid hair concentrations in all children on thrice weekly isoniazid were detectable and displayed variability across a dynamic range
