The observed incidence of CHF in patients with MS who received a mean cumulative dose of 60.5 mg/m(2) MITO was <0.20%. Continued monitoring of patients with MS who are receiving MITO is needed to determine whether the incidence of CHF increases with higher cumulative MITO doses and prolonged follow-up.
Controversy exists in the literature about the significance of primitive reflexes (PR) and extrapyramidal signs (EP) as diffuse cortical dysfunction signs and their relationship to age and cognitive impairment. A sample of 91 patients with a dementia of the Alzheimer type were examined with a standardized technique to assess the relationship between the finding of PR, EP and severity of cognitive impairment measured by Mini-Mental Status Examination. The value of a short cognitive test, the reflective apraxia (i.e. imitation of meaningless gestures), were also assessed. A significantly lower MMS score was correlated with the number of present PR and with presence of snout, sucking and grasping reflexes. No correlation was found between presence or absence of PR and age, depression, or drug therapy. EP score was correlated with the number of present PR and MMS, but not with age. Reflective apraxia score was significantly correlated with the degree of cognitive impairment and was found with lower cognitive impairment than PR.
Murine monoclonal antibodies (MAbs) specific for DNA-RNA hybrids were successfully produced with two different heteropolymers as antigens, cDNA-mRNA and +X174 DNA-RNA heteroduplexes. The former was simpler to prepare. Both had shown similar immunogenicities. Two different immunoglobulin M MAbs were isolated. The 20D3 MAb, generated with the +X174 DNA-RNA hybrid, showed association constants of 1.05 x 1o12, 2.12 x 1010, and 1.68 x 107 for the antigens +X174 DNA-RNA, cDNA-mRNA, and poly(rA)-poly(dT), respectively. The 6B5 MAb, obtained with the cDNA-mRNA hybrid, showed association constants of 1.59 x l0S, 5 x 1012, and 7.1 x 108 for the above-described antigens, respectively. With the 20D3 MAb, an immunoassay was developed for the detection ofListeria DNA-RNA hybrids. In brief, a biotinylated rRNA gene probe specific for the genus Listeria was hybridized with rRNA in the solution phase. The hybrids thus formed were then captured in microtiter plate wells precoated with the purified 20D3 MAb, and the probe-target hybrids were detected with a streptavidin-alkaline phosphatase conjugate. This assay was shown to be specific for the genus Listeria and highly sensitive, allowing the detection of as little as 2.5 pg of target rRNA.
A young woman was admitted with acute anterior myocardial infarction. Emergency coronary angiography showed a total occlusion of the LMCA. Selective infusion of streptokinase recanalized the left main coronary artery (LMCA), the circumflex artery, and the first diagonal, but not the entire left anterior descending artery (LAD). The right coronary artery was dominant and normal. The left‐sided congestive heart failure was severe; treatment improved the heart failure and the patient was discharged on Day 25. She was readmitted for control 28 months later: she was only moderately disabled and coronary angiography showed the same occlusion of the LAD; result on ejection fraction (right anterior oblique view 30d̀) was not significant, but circumflex artery recanalization probably preserved lateral wall contraction. The presence of a normal dominant right coronary artery seems to be a very important factor in contributing to initial survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
