Solvent Extraction of Cadmium(II) with Benzoyltrifluoroacetone in the Presence of Certain Auxiliary Ligands

Extraction of cadmium(II) from aqueous acetate buffered media with benzoyltrifluoroacetone (BTA) in benzene has been studied with and without the addition of auxiliary ligands like pyridine (PY), 3-methylpyridine (3MP), 4-methylpyridine (4MP), pyridine N-oxide (PO), 2-methylpyridine N-oxide (2MPO), 4-methylpyridine N-oxide (4MPO), tributylphosphate (TBP) and trioctylphosphine oxide (TOPO). Synergistic enhancement was observed in all systems. Extraction constants and adduct forma ti on constants have been calculated. Adduct formation constants increase in the following order

A Flexible Architecture for the Computation of Direct and Inverse Transforms in H.264/AVC Video Codecs

A new high throughput and scalable architecture for unified transform coding in H.264/AVC is proposed in this paper. Such flexible structure is capable of computing all the 4x4 and 2x2 transforms for Ultra High Definition Video (UHDV) applications (4320x7680@ 30fps) in real-time and with low hardware cost. These significantly high performance levels were proven with the implementation of several different configurations of the proposed structure using both FPGA and ASIC 90 nm technologies. In addition, such experimental evaluation also demonstrated the high area efficiency of theproposed architecture, which in terms of Data Throughput per Unit of Area (DTUA) is at least 1.5 times more efficient than its more prominent related designs(1)

MULTIPLE CUTANEOUS PILOLEIOMYOMA WITH UTERINE FIBROIDS (REED\u27S SYNDROME): A RARE CASE REPORT

Cutaneous leiomyomas comprise approximately 5% of all leiomyomas. Solitary occurrence is more common than generalized. Multiple cutaneous piloleiomyomas are rare, painful and difficult-to-treat benign tumors originating in the arrectores pilorum muscles of the hair follicles. Multiple Cutaneous piloleiomyomas are associated with uterine fibroids in women (Reed\u27s syndrome) and it is a marker of a condition called hereditary leiomyomatosis and renal cell cancer (HLRCC). We report a case of multiple cutaneous piloleiomyoma with uterine fibroid in an adult female. Because of its rarity and association with renal cell cancer, it deserves a mention in literature.

Cavernous haemangioma of spleen: a rare case report

Tumours of the spleen are as such rare. Of these rare tumours, haemangioma is the most commonly encountered benign tumour with fewer than 100 cases reported. It is either an incidental finding or presents as splenic enlargement or with complications. Preoperative investigations are often inconclusive and may not distinguish between haemangioma and metastases. We report a case of 40 years female with cavernous haemangioma of spleen presenting as massive splenomegaly. Splenic haemangioma presenting as massive splenomegaly is extremely rare and deserves a mention

Clinicopathological study of salivary gland tumors: An observation in tertiary hospital of central India

Background: The salivary glands are one of the few tissues in the body that are subjected to diverse and heterogeneous range of tumors and tumor like conditions. The relative infrequency of these tumors makes their diagnosis and management quite complicated. Fine needle aspiration cytology (FNAC) is a useful diagnostic procedure which has a recognized role in the evaluation of salivary gland lesions. A pre-operative diagnosis about nature of lesion, whether benign or malignant, will help in making decision about proper management of patient.Objective: Aim of this study was to know the epidemiology of salivary gland tumors in our region and to evaluate sensitivity, specificity and diagnostic accuracy of fine needle aspiration cytology taking histopathology as the gold standard. Method: It was prospective observational study conducted in department of pathology in our institute. Total 100 cases were studied with particular reference to age, sex, site, cytologic details & histological types as per WHO classification. FNAC & histopathological examination was done in all cases. Correlation between cytological & histopathological diagnoses was assessed. Diagnostic accuracy of FNAC was evaluated by comparing cytological & histopathological diagnoses.Results: Parotid gland was the most common site of involvement (70% cases). Maximum number of patients was in age range of 41-50 years & male to female ratio was 0.8:1. Most common benign & malignant tumors were pleomorphic adenoma (69.89% cases) & mucoepidermoid carcinoma (8.60% cases) respectively. On cytology, 93 cases while on histopathology 96 cases were diagnosed as neoplastic. Cytological diagnoses correlated with histopathological diagnoses in 94% cases. Sensitivity, specificity & diagnostic accuracy of FNAC were found to be 96.87%, 100% & 96% respectively. Conclusion: FNAC in salivary gland masses is fairly reliable for correct preoperative diagnosis. Multiple sampling and special attention to cytologic features should help to minimize errors.
