the 17-4ph alloy is a martensitic stainless steel with 3–5 wt% cu, strengthened by the precipitation hardening. due to excellent mechanical properties, corrosion resistance and ease of heat treatment, this alloy has unique applications in nuclear power plants and marine constructions. in this paper, the influence of ageing heat treatment, solution annealing followed by ageing at 480, 550 and 62...

BACKGROUND The goal of this study was to know the identity of Leishmania species responsible of cutaneous leishmaniasis (CL) in Fars Province, southern Iran. METHODS Five counties of Shiraz, Firouz Abad, Ghir-Karzin, Farashband and Larestan were prospected. Forty-four patients exhibiting cutaneous lesions were selected. Samples collected on skin lesions were examined both microscopically (aft...

background: one of the most important enzymatic disorders that interact with malaria is deficiency of g6pd (gloucose-6-phosphate dehydrogenase). this enzyme protects red blood cells from hydrogen peroxide and other oxidative damages. distribution of this enzyme deficiency usually accompanies with low level distribution of malaria disease in most malarious areas. so this hypothesis may be consid...

In the present study we have used electron microscopical NADPH-diaphorase (NADPH-d) histochemistry as a visualization procedure for nitric oxide synthase (NOS) to examine patterns of activity in the subcellular distribution of NADPH-d in the rat striatal astroglia. Electron microscopical examination revealed deposition of the NADPH-d reaction product in a nuclear envelope, fragments of endoplas...

An electron microscopical and biochemical examination of the properties of infectious pancreatic necrosis virus (IPN) and of its ribonucleic acid (RNA) was made. The buoyant density of IPN in CsCl was found to be 1.33 g/cm(3). Electron microscopical examination of the banded virus revealed structures similar in size (74 nm) and shape to reoviruses but lacking a characteristic inner capsid struc...

Four patients developed clinically important portal hypertension with histological features of idiopathic portal hypertension while they were receiving cytotoxic drugs for chronic myeloid leukaemia and Hodgkin's disease. Mild sclerosis of some small portal triads was the only abnormality seen at light microscopical examination in three of the four cases. In the remaining case light microscopica...

L I G H T microscopical investigations of the neurones of pulmonate gastropods reveal that certain nerve-cells contain neurosecretory droplets. This has been observed in Basommatophora (Grzycki, 1951; Lever, 1957, 1958; Lever, Kok, Meuleman, andjoosse, 1961 ;Wautier, Pavans de Ceccatty, Richardot, Buisson, and Hernandez, 1961) and in stylommatophoran slugs, such as Limax, Milax, and Arion (Herl...

A 32-year-old woman was admitted to hospital complaining of right upper quadrant and epigastrium abdominal pain, and nausea. On routine physical examination an abdominal mass was discovered on the right upper quadrant. Liver tests were normal. Magnetic resonance imaging of the abdomen revealed a low-density cystic mass. A cystectomy was performed. Hydatid sand containing a protoscolex of Echino...
