Abstract: Method and apparatus to determine the speed of sedimentation of blood and other parameters connected thereto, said method being carried out by detecting the development over time of the optical density, or absorbance, of a sample of blood, said sample being sent in the form of a flow inside a capillary container, said detection being made in correspondence with a point of said capillary container and the relative data acquired being processed to obtain said speed of sedimentation and said connected parameters, said method providing to instantly interrupt the flow of the blood sample flowing inside said capillary container, in order to determine a thickening of the red cells in said blood sample and their consequent sedimentation, said detection being made substantially simultaneously with said instant interruption.

Abstract: The present invention provides a more efficient and faster way to prepare tissue samples for sectioning. More particularly, in accordance with the present invention, a tissue sample is embedded in a porous embedding media in a desired orientation, processed, and sectioned all while being held in the porous embedding media. The post-tissue processing step of manual embedding in paraffin is eliminated from the process.

Abstract: A method of collection of the fragrance ingredient of fragrant wood comprises extracting an essential oil ingredient by a solvent from the fragrant wood and collecting the fragrance ingredient in a vapor-phase by heating the extract, a perfume composition contains the fragrance ingredient, and a cosmetic contains the fragrance ingredient. The fragrance ingredient is obtained without a burnt smell, and it has an aroma of the fragrant wood.

Abstract: The present invention relates to a process for preparing or selecting compositions having a fragrance burst of at least 20% relative to a product before dilution as well as enhanced deposition. The composition is selected such that perfume and surfactant in said composition yields a calculated “Perfume Burst Index” (PBI) value of less than 3 as per algorithm defining the PBI.

Abstract: The present invention provides a method for quantitatively determining hydrogen sulfide or sulfide ions conveniently with high sensitivity, which comprises adding to a sample containing hydrogen sulfide or sulfide ions, metal ions or a compound which liberates said metal ions and a metal indicator which reacts with the metal ions and resultingly undergoes color development, wherein the color development is accelerated or inhibited by the hydrogen sulfide or sulfide ions; and measuring the degree of color development of the metal indicator.

Abstract: The object of the present invention is to measure a concentration of protein stably at a temperature not higher than 25° C., which is a possible ambient temperature at home, and further to expand the measurable concentration range while preventing an obstruction due to a suspending particle such as a bubble and the like, using a reagent prepared by mixing an acid in a solution containing tannin, tannic acid and m-galloyl gallic acid. By mixing the reagent in a solution to be detected to opacify the solution, intensities of at least a transmitted light or a scattered light of the solution to be detected is measured, and a protein concentration thereof is determined based on the intensity. The present invention also provides a method for measuring a concentration of a solution and a method of urinalysis, wherein a protein concentration is measured after measuring an angle of rotation.

Abstract: Disclosed is a process for indicating the presence of soluble fluoride ions in oral care compositions comprising making a signal solution and then bringing the signal solution into contact with an oral care composition and a color change occurs if an effective amount of soluble fluoride ion is present in the oral care composition. Further disclosed are test compositions for use in such process.

Abstract: There is disclosed a method for detecting the presence of bacterial vaginosis in a female subject comprising the steps of: obtaining a sample from the vaginal region of the subject; detecting acetic acid present in the sample; and correlating the presence of detected acetic acid with the presence of bacterial vaginosis.

Abstract: The present invention provides a fragrance precursor of formula I: that is capable of forming a fragrant ketone of formula II: and a fragrant lactone of formula III:

Abstract: The disclosure describes a method for detecting conditions indicative of sepsis. In one embodiment of the invention, an increase in the level of 3-chlorotyrosine or 3-bromotyrosine from the normal level in a sample of body fluid or tissue is indicative of early sepsis or infection. In another embodiment of the invention, the level of 3-chlorotyrosine or 3-bromotyrosine is measured or monitored to determine the response to therapeutic treatment of the infective condition in which a reduction in the level that existed prior to the treatment is an early sign or indication that the treatment is working in vivo. In a preferred embodiment, the method of the invention is illustrated in a clinically relevant mouse model of sepsis.
