dear editor-in-chief a 28 yr male was presented in october 2015 at medicine outpatient department, safdarjung hospital, new delhi- india with generalized weakness, fever and cough for preceding 15 days. clinicoradiologic examination revealed pallor, firm, non-tender splenomegaly measuring 13.7 cm and hepatomegaly (liver span - 16.9 cm). however, no lymphadenopathy was found.

Eukaryotes contain inorganic polyphosphate (polyP) and acidocalcisomes, which sequester polyP and store amino acids and divalent cations. Why polyP is sequestered in dedicated organelles is not known. We show that polyP produced in the cytosol of yeast becomes toxic. Reconstitution of polyP translocation with purified vacuoles, the acidocalcisomes of yeast, shows that cytosolic polyP cannot be ...

Hairy cell leukemia is an indolent, chronic B-cell lymphoproliferative disorder comprising approximately 2 to 3% of all adult leukemias in the United States. Hairy cells are clonal expansions of mature, activated B-cells. They co-express CD11c, CD19, CD20, CD22, CD25, and CD103. Hairy cells possess clonal immunoglobulin gene rearrangements and express monoclonal surface immunoglobulin of either...

Free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. We aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (MDA) formation, and the antioxidant composition of r...

Background: Papaver bracteatum Lindl. Commonly known as Iranian poppy is an important medicinal plant due to the presence of benzylisoquinoline alkaloids. Objective: To evaluate the hairy root culture as a novel method for thebaine production. Methods: To optimize the hairy root culture of P. bracteatum, five strains of Agrobacterium rhizogenes (ATCC15834, C318, A13, 9453 and A4) were used by...

Vertebrate Hairy genes are highly pleiotropic and have been implicated in numerous functions, such as somitogenesis, neurogenesis and endocrine tissue development. In order to gain insight into the timing of acquisition of these roles by the Hairy subfamily, we have cloned and studied the expression pattern of the Hairy gene(s) in amphioxus. The cephalochordate amphioxus is widely believed to b...

introduction: nasal polyps are benign prolapsed mucosal lesions which commonly arise from the paranasal sinuses and lateral walls of the nose especially the contact areas of osteomeatal complex. though nasal polyps arising from the nasal septum have been reported, those arising from its anterior part are extremely rare and present a diagnostic dilemma.  aetiology is multifactorial and is mainly...

The commonest pathologic diagnosis of large prolapsed polyps is leiomyoma. Benign or malignant adenomyomatous polyps follow. Adenomyotic cyst is a rare form of adenomyosis. To our knowledge, a recurrent prolapsed giant uterine polyp comprised of adenomyotic cysts and with different pathogenesis from the original polyp has not been reported in the literature. This case report describes a 29 year...

The BRAF-V600E mutation defines genetically hairy cell leukemia among B-cell leukemias and lymphomas. In solid tumors, BRAF-V600E is known to aberrantly activate the oncogenic MEK-ERK pathway, and targeted BRAF and/or MEK inhibitors have shown remarkable efficacy in clinical trials in melanoma patients. However, the MEK-ERK pathway status in hairy cell leukemia has not been thoroughly investiga...
