A new reagent for the chromogenic Limulus amebocyte lysate (LAL) assay is described. LAL was formulated for optimal performance in either an endpoint procedure or a kinetic procedure with the chromogenic substrate, buffer, and LAL components colyophilized as a single reagent. The kinetic chromogenic method required an incubating microplate reader coupled to a computer for collection and analysi...

Treatment with testosterone (T) or estradiol (E2) facilitates intraspecific aggressive behavior in adult rodents. Brain aromatization of T to E2 appears to be involved in facilitation of fighting behavior. In the present study we measure the in vitro brain aromatase activity (AA) in the preoptic area (POA), amygdaloid nuclei (Am), ventromedial hypothalamus (VMH), and parietal cortex (CTX) from ...

AIM This study was undertaken with the aim to compare and establish the genetic relatedness between classical swine fever virus (CSFV) genogroup 2.2 isolate and pestivirus reference strains. MATERIALS AND METHODS The available complete genome sequences of CSFV/IND/UK/LAL-290 strain and other pestivirus reference strains were retrieved from GenBank. The complete genome sequence, complete open ...

Devendra Lal was an Indian nuclear physicist who began his career studying particle physics while a student at the Tata Institute of Fundamental Research (TIFR) in Bombay, using tracks emulsions to study cosmic ray particles and their interactions. He soon moved on search for radionuclides produced atmosphere by bombardment, independently (with colleagues) discovering radioisotopes Be, P Si the...

The 5 9 ~ o NMR and magnetization measurement in (Lal-,Y,) Co5Hy have been performed at 77 K. The magnetizations of these compounds decrease with increasing hydrogen content (y) and are indepedent of Y-concentration (2). This result can be interpreted by an electron transfer effect in the direction H atom -+ Co atom. The pseudobinary intermetallic compound (Lal-,Y,) C05 have CaCu5 type structur...

The book reviewed here is dedicated to Dr. Bang and contains the proceedings of an "International conference on endotoxin standards and LAL use with parenteral drugs" that was held at Woods Hole in September 1981. Following the first two chapters, which include the keynote address by Dr. Bang and an excellent overview of the value and applications of the LAL test, most chapters are concerned wi...

The measurement of airborne endotoxins is thus far not standardized. Earlier studies reported higher endotoxin yields when Tween 20 was added to the media used for filter extraction and in the Limulus amebocyte lysate (LAL) assay. This study compared four common media and assessed the effects of Tween during extraction and analysis separately. Parallel airborne dust samples from five work envir...

The genetic defect leading to cholesteryl ester storage disease (CESD) has been determined in a 12-yr-old patient. Lysosomal acid lipase (LAL) activity in cultured skin fibroblasts was reduced to approximately 9% of control fibroblasts. Plasma cholesterol (255 mg/dl) and LDL-cholesterol (215 mg/dl) were elevated whereas HDL-cholesterol was reduced (19 mg/dl). Triglycerides were moderately eleva...

We investigate the relationship between two polynomial time languages: Bellantoni and Cook’s functional combinator language BC, and Girard’s Light Linear Logic LAL (as amended by Asperti). It is known that both languages characterize exactly the polynomial time functions. Despite this similarity, an open question has been to provide a compositional translation between the two languages: given a...
