The effects of 13 mutagen-sensitive (mus) mutants (representing seven loci) on mitotic chromosome stability in nonmutagenized cells have been examined genetically. To do this, mus-bearing flies heterozygous for the recessive somatic-cell marker, multiple wing hairs (mwh), were examined for increased frequencies of mwh clones in the wing blade. Mutants at the mus-103, mus-104 and mus-106 loci do...

BACKGROUND With the rapid development of urbanization, pregnant population is growing rapidly in Shenzhen, and it has been a difficulty to serve more and more pregnant women and reduce spatial access disparities to maternity units (MUs). Understanding of the current status of accessibility to MUs is valuable for supporting the rational allocation of MUs in the future. METHODS Based on pregnan...

The presence of autoantibodies in multiple sclerosis (MuS) is well known, but their target antigens have not been clearly identified. In the present study, IgG autoreactivity to neural antigens of normal human white matter separated by bidimensional electrophoresis was assessed in serum and cerebrospinal fluid of 18 MuS and 20 control patients. Broad IgG autoreactivity was detected by two-dimen...

Time course of tetanus recorded during 40 Hz stimulation was examined on 70 motor units (MUs) of medial gastrocnemius muscle in 41 rats. Three types of MUs were distinguished: slow(S), fast resistant to fatigue (FR) and fast fatigable (FF). In fast MUs of either type, the stimulation induced unfused tetanus with noticeable sag. It was found that in cases of tetani in FF MUs, the sag developed e...

BACKGROUND The feasibility as well as the suitability of several therapies for medically unexplained symptoms (MUS) in primary care applied by the family physician (FP) appeared to be low. FPs need effective and acceptable strategies to manage these functionally impaired patients. OBJECTIVE To review important and effective elements in the treatment of patients with MUS in primary care accord...

Male house mice (Mus musculus) emit ultrasonic vocalizations (USVs) during courtship, which attract females, and we aimed to test whether females use these vocalizations for species or subspecies recognition of potential mates. We recorded courtship USVs of males from different Mus species, Mus musculus subspecies, and populations (F1 offspring of wild-caught Mus musculus musculus, Mus musculus...

'The Mouse (Mus musculus) T cell Receptor Beta Variable (TRBV), Diversity (TRBD), and Joining (TRBJ) Genes', the 14th report of the 'IMGT Locus in Focus' section, comprises 8 tables entitled: (1) 'Number of mouse (Mus musculus) germline TRBV genes at 6A-C and potential repertoire'; (2) 'Mouse (Mus musculus) germline TRBV genes at 6A-C'; (3) 'Mouse (Mus musculus) TRBV allele table'; (4) 'Mouse (...

'The Mouse (Mus musculus) T Cell Receptor Delta Variable (TRDV), Diversity (TRDD) and Joining (TRDJ) Genes', the 15th report of the 'IMGT Locus in Focus' section, comprises 7 tables entitled: (1) 'Number of mouse (Mus musculus) germline TRDV genes at 14D1-D2 and potential repertoire'; (2) 'Mouse (Mus musculus) germline TRDV genes at 14D1-D2'; (3) 'Mouse (Mus musculus) TRDV allele table'; (4) 'M...

Homologous recombination and post-replication repair facilitate restart of stalled or collapsed replication forks. The SRS2 gene of Saccharomyces cerevisiae encodes a 3'-5' DNA helicase that functions both in homologous recombination repair and in post-replication repair. This study identifies and characterizes the SRS2 homolog in Neurospora crassa, which we call mus-50. A knockout mutant of N....

An increase in mRNA encoding the secretory form of the mu heavy (H) chain (mus) and in the ratio of mus mRNA to the mRNA encoding the membrane form of the microH chain (micron) occurs in normal B cells stimulated with anti-IgM and BSF-p1 together with the two B cell differentiation factors B15-TRF and EL-TRF. Stimulation of cells with anti-IgM and BSF-p1 with either B15- or EL-TRF causes no cha...
