Green synthesis of nanoparticles using plant source has been given much importance. In the present study, silver nanoparticles (AgNPs) were synthesized using the ethyl acetate and methanol (EA: M 40:60) extracts of the inflorescence of the tree Cocous nucifera. The synthesized nanoparticles were characterized by UV-visible spectroscope, FTIR and TEM(More)
Cadmium is one of the elements found to damage antioxidant systems in mammals. To ameliorate cadmium toxicity and to prevent oxidative stress, natural products may be useful. In Indian ethnobotanical practice, a mixture of 17 herbal products is used to fortify the reproductive system of women after parturition and to reverse ovarian oxidative stress. Oral(More)
Gliomas of the CNS associated with tuberous sclerosis have been well documented; malignant degeneration to glioblastoma multiforme, however, is rare. We studied a 17-year-old boy with stigmata of tuberous sclerosis and a cerebral glioblastoma multiforme. The rarity of this occurrence suggests that neoplasms arising from hamartomas may behave differently(More)
Technetium-99m sulfur colloid (SC) and Technetium-99m pyrophosphate (PYP) scintigrams in a patient with idiopathic systemic amyloidosis were abnormal. Hepatic SC distribution was nonhomogeneous. Spleen showed reduced SC uptake and a large focal defect at its upper pole. Splenic localization of PYP was seen on a bone scan. On histologic examination the(More)
This communication describes the fourth known patient with a terminal long arm deletion of chromosome 10. The karyotype is : 46,XX,del(10)(q26). The clinical findings in the patient included intrauterine growth retardation, microcephaly, truncus arteriosus type 1, respiratory distress and craniofacial dysmorphism. Although review of the limited number of(More)
Clear cell sarcoma was closely mimicked in metastatic tumor deposits from two patients with acral lentiginous malignant melanoma. A subcutaneous deposit composed of glycogen-laden spindle cells dominated the presenting clinical picture in one patient. In the other, primary acral melanoma resembled a histiocytic tumor and metastatic tumor simulated clear(More)
One hundred twenty-seven cases of non-Hodgkin's lymphoma and Hodgkin's disease in children and young adults at the University of Wisconsin Hospital between 1969 and 1980 have been reviewed. Nodular sclerosing was the most frequent histologic type in patients with Hodgkin's disease. Malignant lymphoblastic lymphoma (MLLB) was the most common type of(More)
We report a bronchial carcinoid tumor with distinctive, cytoplasmic, rod-shaped crystalloid inclusions that were visible by light microscopy. These cytoplasmic structures were immunoreactive with antibodies against chromogranin A and synaptophysin in paraffin-embedded tissue. Ultrastructural studies showed them to be paracrystalline in nature and located(More)
The antimicrobial activity of methanol and aqueous extracts of the medicinal plant Cocculus hirsutus was studied using E.coli, Vibrio cholerae, Pseudomonas fluorescence, Klebsiella pneumoniae and Staphylococcus aureus ,Candida gillermontii,Tricophyton rubrum,Tricophyton tansuans,Aspergillus ochraceus,Candida albicans and Rodatrula sp as test(More)
Cells resembling those of Gaucher's disease were found on imprints of a lymph node from a patient with a plasmacytoid lymphoma. These cells contained nonspecific esterase, and electron-dense crystal-like structures. Associated plasma cells stained positively with anti-kappa and anti-mu sera but few macrophages were stained. The resemblance of these(More)
