Oral leukoplakia (OL) is the most common potentially malignant lesions of the oral cavity and Oral squamous cell carcinoma (OSCC) accounts more than 95% of all malignant neoplasms in the oral cavity. Therefore, the aim of this study to report the immunoexpression of metallothionein in dysplastic lesions to correlate with histological grade and OSCC. Samples of 5 normal oral mucosa, 15 dysplastic cases was graded as: mild dysplasia, moderate dysplasia and severe dysplasia and 15 cases of OSCC. Immunohistochemistry for the metallothionein was performed and the Pearson Chi-Square test was used in statistical analysis. The metallothionein stain in all cases exhibits a mosaic pattern and predominantly in cytoplasm and nucleus simultaneously. The total stain was significantly higher in OSCC when compared with normal and dysplastic lesions. Metallothionein expression may play an important role in the conversion of potentially malignant oral lesion to oral carcinoma since its earlier stages.

In order to minimize the use of expensive chemical fertilizers, this study investigate the potential of phosphate solubilization by bacterium isolated from soil which the most of the bacteria isolated from the soil have the ability to dissolve rock phosphates both in the soil and in the culture medium is well known. The microorganisms produce low molecular mass organic acids, which attack the phosphate structure and transform phosphorus from nonutilizable to the utilizable for the plants form. The objective of the present study is to study the factors affecting on dissolution of phosphate content in Abu Tartur phosphate ore by using bacterium isolated from soil. Serial dilution method was performed to inoculum solutions to achieve microorganism’s isolation which obtaining one bacterium that has ability to dissolve phosphate ore and molecular identification by 16 sRNA which suggest it called Azotobacter vinelandii. Optimum conditions of bioleaching of Abu Tartur phosphate ore are 3 days incubation period, modified PVK medium is the best medium for dissolution of Abu Tartur phosphate ore, 0.1x 1029 colony forming unit of Azotobacter vinelandii for 50 ml medium, 0.5% Abu Tartur phosphate ore concentration , 30°c, ammonium oxalate as nitrogen source, glucose as carbon source, ,no significant effect of addition factor, also there is decreasing in pH and increases in electric potential, initial pH 7, which the leaching efficiency of phosphate content in Abu Tartur phosphate ore reaches to 52.6%.

The purpose of clinical crown lengthening is to increase the extent of supragingival tooth structure for restorative or esthetic purposes. The present article aims at comparing three different crown lengthening techniques. This study was conducted in department of periodontics. It included 30 patients, 15 males and 15 females. Patients were equally and randomly divided into three groups. Group I: It included 10 patients treated with gingivectomy. Group II: It included 10 patients treated with apically repositioned flap. Group III: It included 10 patients treated with surgical extrusion using periotome. Length of clinical crown, width of attached gingival and interdental papilla height was recorded preoperatively and postoperatively. There was no change in the width of attached gingiva and minimal change in the interdental papilla height between pre-operative and post-operative measurements in the crown lengthening procedure done by surgical extrusion using periotome when compared to the other conventional surgical procedures. The difference among three techniques was significant (p-0.01). Author concluded that crown lengthening using surgical extrusion technique is effective in grossly fractured teeth and in area where crown structure is less.

Moraxella osloensis is a rare causative agent of infection in humans with most cases reported in immunocompromised patients. We report a case of 40years old chronic alcoholic patient who presented with septic arthritis of left knee joint. Culture of pus aspirate was found to be positive for gram negative coccobacilli that were aerobic, oxidase positive and catalase positive. M.osloensis was identified by Biochemical tests and Vitek 2 Compact. Prompt control of infection was achieved by treatment with Meropenem for 7 days along with debridement of left knee joint.

Sunflower is an important oil seed crop in India. The crop is susceptible to various diseases among which leaf blight caused by Alternaria helianthi is more destructive. The present study aimed at determining antifungal potential of Moringa stenopetala (Baker f.) Cufod (Moringaceae) an indigenous plant to Ethiopia against A. helianthi isolated from sunflower leaves. Antifungal activity was determined by Poisoned food technique. The extract was effective and a dose dependent inhibition of mycelial growth of fungus was observed. At extract concentration 1.5mg/ml and higher, an inhibition of >70% was observed. The plant appears promising and the presence of bioactive principles in the extract might have accounted for the antifungal activity. The plant can be used in the management of leaf blight of sunflower.

Lactococcus garvieae is a Gram-positive coccus [GPC] that has morphological and biochemical similarities to enterococci. L.garvieae strains are rare human pathogens, with only a few cases reported in the literature, mainly as a cause of infective endocarditis but a well-known pathogen in aquaculture. It is well known as a fish pathogen, and in some of the reported cases, the patients had history of contact with raw fish. We report a case of L. garvieae urosepsis in a patient with no history of contact with raw fish.
