A Fluorescence Staining Method for Studying Sperm Membranes

P-9: A New Morphology Staining Method for Sperm of Some Domestic Animals

Background: There are some methods for morphology staining of sperm. Although many different and also new methods are used in semen analysis, light microscopy is still used for routine morphological evaluation. The most used of the methods is Papanicolaou staining. This method is routinely used in Andrology laboratory for Human sperm morphology staining. In some domestic animals such as bull, R...

Chlorophyll Fluorescence: A Novel Method to Screen for Herbicide Resistance

The susceptibility to Terbacil of six randomly selected strawberry cultivars (‘Aromas’, ‘Chambly’, ‘Harmonie’, ‘Kent’, ‘La Clé des Champs’ and ‘Seascape’) was analysed using chlorophyll florescence (CF) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. Terbacil was applied at one of five rates...

Chromomycin A3 Staining Indicates Sperm Protamine Deficiency

Chromomycin A3 binds to DNA and Protamine -deficient spermatozoa look bright yellow,whereas normal spermatozoa appear dull yellow.

A new method for studying the vibration of non-homogeneous membranes

We present a method to solve the Helmholtz equation for a non-homogeneous membrane with Dirichlet boundary conditions at the border of arbitrary two-dimensional domains. The method uses a collocation approach based on a set of localized functions, called ”little sinc functions”, which are used to discretize two-dimensional regions. We have performed extensive numerical tests and we have compare...
