Secondary wall thickenings in tracheary elements were specifically stained by incubation of Arabidopsis and maize in Silver Stain Plus (Bio-Rad) staining solution, after pretreatment with SDS and ethanol solution. Scanning electron microscopic analysis of sections of celery revealed that silver particles were deposited on the secondary wall thickenings, indicating that the staining was due to t...

Bartholomew and Mittwer (1951) presented photographic evidence that the gram-positive staining area of bacterial cells could be fitted internally to the area demonstrated by the Dyar cell wall stain. Their conclusion was that the bacterial cell wall was not included in the grampositive area. Lamanna and Mallette (1954) explained Gram differentiation of intact cells on the basis that crystal vio...

The morphology of the vallate papillae from postmortem human samples was investigated with immunohistochemistry. Microscopically, taste buds were present along the inner wall of the papilla, and in some cases in the outer wall as well. The typical taste cell markers PLCβ2, GNAT3 (gustducin) and the T1R3 receptor stain elongated cells in human taste buds consistent with the Type II cells in rode...

The Masson-Fontana silver stain for melanin was employed for the differentiation of pathogenic fungal species in human or mouse tissues. The fungi studied were Candida albicans, Candida tropicalis, Candida glabrata (Torulopsis glabrata), Cryptococcus neoformans, Cryptococcus bacillisporus, Coccidioides immitis, Blastomyces dermatitidis, Histoplasma capsulatum, Paracoccidioides brasiliensis, Spo...

Kasimiye Medresse, one of the most important educational centers of its times, has a sacred value for people in Mardin. The reason is that the s...

BACKGROUND To characterize the histological changes within the posterior calcaneal cartilage in patients with insertional Achilles tendinopathy (IAT) and test the relationships between severity of the histological changes and level of functional impairment. METHODS Sixteen posterior calcaneal wall specimens of patients with IAT who had posterior calcaneal ostectomy were investigated. Hematoxy...

The first phase of bacterial cytokinesis was described by Knaysi (1951) as involving an inward growth of the cytoplasmic membrane to form a septum across the cell. Transverse plasma rnembranes or boundaries were previously reported by Migula (1894) in Bacillus oxalaticus, by Guillermond (1908) in Bacillus mycoides, by Knaysi (1930) in B. mycoides and Bacillus mesentericus, and by Robinow (1942,...

statement of problem: primary teeth discoloration can cause mentally and socially unpleasant effects in children. this can also be a sign of systemic disease. despite the importance of this subject, a comprehensive study has not been performed yet. purpose: the aim of this study was determining the frequency of different types of primary teeth discoloration. materials and methods: in this cross...
