Biological Assay of Cephalosporin C [PDF]

Journal of General Microbiology, 1962
SUMMARY: A method of assaying the antibiotic cephalosporin C in low concentration in culture fluids by using a strain of Vibrio cholerae is described. The formation of spheroplasts of the test organism in subinhibitory concentrations of the antibiotic and chemically related compounds is discussed.

Sequential Sampling in Biological Assay [PDF]

Nature, 1953
IN an investigation relating to the isolation and purification of chorionic gonadotrophin from pregnancy urine, the following problem has arisen : “Does fraction A contain at least the amount X of chorionic gonadotrophin?” It was necessary to answer this question in the shortest possible time and to use as little material of A as possible.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Integrative Approaches for Predicting in vivo Effects of Chemicals from their Structural Descriptors and the Results of Short-term Biological Assays

Current Topics in Medicinal Chemistry, 2014
Cheminformatics approaches such as Quantitative Structure Activity Relationship (QSAR) modeling have been used traditionally for predicting chemical toxicity. In recent years, high throughput biological assays have been increasingly employed to elucidate

Mathematics of Biological Assay

Nature, 1944
IF in a biological assay the mean responses, y11, y12, of two groups of n animals to doses of a standard preparation the logarithms of which are x11, x12, are compared with the mean responses, y21, y22 to doses of the preparation under test the logarithms of which are x21, x22, it is often possible to express the relationship between dosage and ...

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.
