A new class of slow-growing non-perithecial mutants ofAspergillus nidulans

A slow growing non-calcified airway mass.

mediciNe & HeAltH/RHode islANd lAryngeAl ChondrosArComA Is A rAre relAtIVely slow-growIng tumor arising from the largyngeal cartilages. The slowly progressive nature of symptoms means that many patients will undergo multiple diagnostic studies, and recognition of the imaging characteristics of the tumor may assist significantly in diagnosis. We present a case of a laryngeal chondrosarcoma lacki...

Evaluation of Non- linear Growth Curves Models for Native Slow-growing Khazak Chickens

Native poultry is a valuable genetic source with high resistance against diseases providing an important subject for breeding programs. The non-linear mathematical modeling of the growth pattern may partly explain the relationship between requirements and body weight to precise feeding that plays a vital role in the animal enterprises. A study was conducted to compare five non-linear models inc...

Isolation and characterization of perithecial development mutants in neurospora.

The isolation and characterization of mutants that block perithecial development in Neurospora crassa are described. Several classes of mutants have been isolated after UV mutagenesis, and those that block perithecial development when used as the female (protoperithecial) component of a cross have been further characterized. These mutants fall into 29 complementation groups. Twelve of the 33 mu...

Mycobacterium sherrisii sp. nov., a slow-growing non-chromogenic species.

'Mycobacterium sherrisii' is an undescribed species that appears to be emerging, in particular, among HIV-positive patients originating from Africa. To describe 'M. sherrisii', to ensure that the species name is validly published and to define its phylogenetic position, we collected 11 of these strains reported in five previous studies, and subjected them to biochemical identification, cell-wal...
