Despite the extensive use of nanoparticles (NPs) in various fields, adequate knowledge human health risk and potential toxicity is still lacking. The lymphocytes play a major role immune system, it can alter antioxidant level when exposed to NPs. Identification hazardous NPs was done using vitro tests this study mainly focuses on comparative cytotoxicity genotoxicity four different including cobalt (II, III) oxide (Co 3 O 4 ), iron (III) (Fe 2 silicon dioxide (SiO aluminum (Al ) lymphocytes....

Abstract: The protective role of leaves Mentha piperita Linn (Mint) was studied in adult Swiss albino mice against arsenic‐induced hepatopathy. animals were divided into four groups. Group I: only vehicle (0.9% NaCl) administered. II: the received leaf extract (1 g/kg body weight per day) orally for 30 days. III: treated with sodium arsenite (4 mg/kg weight) intraperitoneally 0.9% NaCl. IV: given 10 consecutive days prior to treatment and continuously after treatment. from above groups...

In this work, polymer blend films based on polyvinyl alcohol (PVA)/poly(ethylene glycol) (PEG) were prepared by solution casting technique. X-ray diffraction (XRD) analysis was performed to investigate the structural details of blend. XRD pattern confirms polycrystalline nature films. Sandwich structures type Ag-PVA/PEG-Ag formed study dielectric and conduction properties in frequency range 300 Hz–3 MHz at different temperatures varying from 298 K 420 K. Experimental results show that both...

Flexible dielectrics with high permittivity have been investigated extensively due to their applications in electronic industry. In this work, structural and electrical characteristics of polymer based film analysed. Poly vinyl alcohol (PVA) was prepared by solution casting method. X-ray diffraction (XRD) characterization technique is used investigate the properties. The semi-crystalline nature has determined analysis obtained XRD pattern. Electrical properties synthesized analysed from C-V...

Obstructing esophageal cancer produces severe dysphagia with ensuing death within 90 days. Palliation is possible modalities like stent placement, laser, and photodynamic therapy. However, these treatments have a high rate of complications, the overall mortality not altered. A new alternative treatment evaluated in this study endoscopic intratumoral injection cisplatin/epinephrine (CDDP/epi) gel. CDDP/epi gel injections were administered weekly for 3 to 8 weeks nine patients, median age, 72...

Malaria remains an important cause of morbidity and mortality in India. Though many comprehensive studies have been carried out Africa Southeast Asia to characterize examine determinants Plasmodium falciparum vivax malaria pathogenesis, fewer conducted India.A prospective study malaria-positive individuals was at Goa Medical College Hospital (GMC) from 2012 2015 identify demographic, diagnostic clinical indicators associated with P. infection on univariate analysis.Between 2015, 74,571...

Culture-adapted Plasmodium falciparum parasites can offer deeper understanding of geographic variations in drug resistance, pathogenesis and immune evasion. To help ground population-based calculations inferences from culture-adapted parasites, the complete range a study area must be well represented any collection. this end, standardized adaptation methods determinants successful vitro adaption were sought. Venous blood was collected 33 P. falciparum-infected individuals at Goa Medical...

Previous whole genome comparisons of Plasmodium falciparum populations have not included collections from the Indian subcontinent, even though two million Indians contract malaria and about 50,000 die disease every year. Stratification global parasites has revealed spatial relatedness parasite genotypes on different continents. Here, genomic analysis was further improved to obtain country-level resolution by removing var genes intergenic regions distance calculations. P. genomes India were...

In the present paper, investigations of CdSe loaded poly(diallyl dimethyl ammonium chloride) (PDADMAC) nanocomposites and pure PDADMAC synthesized by wet chemical technique have been carried out. Fourier transform infrared X-ray diffraction analysis performed to reveal structural details polymer nanocomposite (PNC). The dielectric behavior PNC has recorded, which results in higher value real imaginary part constant for PNC, as compared with PDADMAC. increase is attributed addition quantum...

Pregnancy tumours (PTs) are a non-neoplastic, reactive, inflammatory conditional gingival enlargement which occurs in the oral cavity during pregnancy. The lesion most frequently on gingiva but may also develop lip, tongue, mucosa and palate. When large PT develops, it can interfere with mastication, speech, maintenance of hygiene be aesthetically disfiguring. treatment PTs depends upon size lesion; smaller lesions regress after parturition however need to surgically removed. Conventional...

The present study was undertaken to establish the seasonal variations in semen biochemical indices Bhadawari bull. Four fertile, healthy adult bulls aged between 2 4 years were used as donors. conducted over a period of six months and divided into three seasons winter season (February-March), dry summer (April-May) wet (June-July). Sixteen samples collected each (four ejaculates from bull) by using Artificial Vagina seminal plasma harvested centrifugation. results showed gradual significant...
