Serum selenium concentration and antioxidant activity in cervical cancer patients before and after treatment

Aim - in the present study, the effect of chemo and radio therapies on serum trace elements content and antioxidant activity in blood serum of cervical cancer patients was evaluated. Among 104 cervical cancer patients selected for the present study, 54 and 50 patients were treated with chemo- and radiotherapy respectively. Plasma Se, Zn, Cu and some enzymatic antioxidants activities were estimated in serum before and after the treatment. The decreased levels of serum trace elements, glutathione peroxidase activity and total antioxidant capacity, and increased malondialdehyde, glutathion reductase was observed in cervical cancer patients when compared to healthy controls. The increased concentration of serum Se, Zn was observed in patients treated with chemotherapy. Simultaneously there was a significant (P << 0,001) increase in glutathione peroxidase and total antioxidant capacity, and significant decrease (P << 0,05) in malondialdehyde and glutathion reductase levels in the serum of patients treated with chemotherapy compared to the patients treated with radiotherapy

A simple and efficient synthesis of substituted pyrazoles

A novel route for the formation of 3-aryl-1-phenyl-1H-pyrazoles was discovered upon the reaction of 3-aryl-1-phenyl-4,5-dihydro-1H-pyrazole-5- carbonitrile with potassium hydroxide in the presence of a phase transfer catalyst (tetrabutylammonium bromide) in THF as a solvent, and a single crystal X-ray study is reported

Head and Neck Lymphomas: Tip of the Iceberg?

ABSTRACT Background: Lymphomas comprise around 5% of all head and neck neoplasms and is the second most common extra nodal non hodgkin&apos;s lymphoma (NHL). However there is sporadic data on this entity from the subcontinent and hence we undertook this study. Methodology: This retrospective observational study was conducted at a tertiary care oncology center in India on diagnosed cases of NHL between January 2007 and December 2013. All patients were diagnosed based on histopathology and immunohistochemistry. Staging work up was done in all patients. Patients were considered as primary Head and Neck lymphomas if there was head and neck as the predominant site with or without regional lymph node involvement. Results: A total of 39 patients were studied. The age at presentation ranged from 29 to 78 years. The most common site of presentation was oral cavity (26%; n=10), followed by parotid and thyroid (18% each; n=7), eye (12%, n=5), maxilla (8%; n=3), paranasal sinuses (8%; n-=3) cheek (8%, n=3), and nasal cavity (2%, n=1). 41% (n=16) cases were in stage I, 43% (n=17) in stage II, 3% (n=1) in stage III, and 13% (n=5) were in stage IV. Most common histology was DLBCL (71%; n=28), followed by plasmablastic (10%; n=4), marginal zone (8%, n=3), mantle cell (3%; n=1), follicular lymphomas (5%; n=2), and NK/T cell lymphoma (3%; n=1). Most of the patients were of low risk (67%; n=26), followed by intermediate (23%; n=9), and high risk (10%; n=4). Patients were treated with anthracycline based chemotherapy +/-radiotherapy. In this study, stage I and stage II patients had a better prognosis and overall survival, median OS 28 months and 11 months, respectively. In stage III and IV, it was 7 and 3 months, respectively. According to site, the best median overall survival was seen with parotid (27 m), paranasal sinus (26m), and oral cavity (23 m), followed by thyroid (18 m) nasal cavity (17 m), maxilla (11 m), eye (8 m), and cheek (7 m)

Synthesis, characterization and some properties of lanthanum complex of N,N `-bis-(2-butyl-5-chloro-3H-imidazol-4-ylmethylene)-ethane-1,2-diamine, a salen type ligand

Diamagnetic lanthanum complex was prepared with a salen type ligand ``imidozalen'', bis(2-n-butyl-4-chloro-imidazole)-5-iminoethane and the complex was characterized by elemental analyses, magnetic studies, UV-Vis and IR, spectroscopy, NMR, thermal and conductance studies. Antifungal and antibacterial properties were also studied. The complex has a potential as an epoxidation catalyst

Herbal remedies for the management of seed-borne fungal pathogens by an edible plant Decalepis hamiltonii (Wight & Arn)

Abstract Antifungal activity-guided assay of solvent extracts of Decalepis hamiltonii (Wight & Arn) (Asclepiadaceae) against important phytopathogenic fungi, known to cause diseases in sorghum, maize and paddy proved to be highly significant. Among the five solvent extracts tested, Petroleum ether extract showed highly significant antifungal activity. Phytochemical analysis revealed that the antifungal active principle is a phenolic compound. TLC separation of the phenolic fraction using chloroform as an eluting solvent revealed the presence of seven bands but the antifungal activity was observed only in band five with Rf value 0.77. The antifungal active compound is identified as 2-hydroxy-4-methoxybenzaldehyde based on Nuclear Magnetic Resonance (NMR) and mass spectral analysis. The Minimal inhibitory concentration (MIC) varied between 200 μg ml−1 and 700 μg ml−1 depending on the fungal species. Seed treatment of the active principle significantly increased seed germination and seed vigour with a corresponding decrease in seed mycoflora. The antifungal active compound was effective against all the 24 fungal species tested suggesting broad-spectrum antifungal activity. Comparative evaluation of the active principle with the synthetic fungicides revealed that the antifungal activity of the active principle obtained from the plant is better than that of synthetic fungicide. This plant being an edible one can be exploited in the management of seed-borne pathogenic fungi and the prevention of biodeterioration of grains and mycotoxin elaboration during storage

When hydrogen bond tailors molecular packing in non-anisometric molecules. The case study of N-alkyl 1,3-diphenyl-4,5-dihydro-1H-pyrazole-5-carboximidamides

In this paper, we report the synthesis of novel liquid crystals (LCs) based on 5-membered pyrazoline heterocycle. The synthesis of pyrazoline derivative was carried out by 3 + 2] 1,3-dipolar cycloaddition reaction of benzaldehyde phenyl hydrazone (1) with acrylonitrile, mediated by chloramine-T as the oxidising agent, followed by addition of hydroxylamine hydrochloride, and subsequently alkylated with various alkyl chains to afforded the title compounds. The LCs properties were investigated using differential scanning calorimetry and polarising optical microscopy. For title compounds with longer alkyl chains, monotropic columnar hexagonal mesophase was characterised by XRD analysis. The mesophase-formation was driven by intermolecular hydrogen bonds despite their non-discoid molecular structure. GRAPHICS]
