ALTJHoUGH the Barcroft apparatus is used extensively for the study ofrespiration in biological fluids, we have found no published work in which the accuracy of the results obtained has been submitted to a critical examination. This is somewhat surprising when it is considered that the Barcroft apparatus is employed so frequently for comparative work where the interpretation is often founded on ...

The impact of concrete composition and roughness on the formation microalgal biofilms their photobiology were studied marine infrastructures presenting four different compositions combined with two degrees (rough smooth). structures first inoculated a natural microphytobenthic biofilm immersed in sterilised seawater controlled photoperiod for six days. Photosynthetic activity was assessed an im...

The bodies and faecal pellets of the house dust mite (HDM), Dermatophagoides pteronyssinus, are the source of many allergenic and nonallergenic proteins. One of these, the 14-kDa bacteriolytic enzyme LytFM, originally isolated from the spent HDM growth medium, may contribute to bacteriolytic activity previously detected by zymography at 14 kDa in the culture supernatants of some bacterial speci...

Introduction Allergy to cow’s milk (CM) proteins has as major allergens caseins (60%), b-lactoglobulin (9%) and a-lactalbumin (4%). Thermal processes for milk industrialization include: pasteurization (low: 63 ° C for 30 min or High: 72 ° C for 15 seconds), UHT heating (145 ° C for 1-2s) and sterilization (115 ° C for 15 min).It’s accepted that these processes denature milk proteins in differen...

A disease survey was carried out in Tamil Nadu, India during 2021 to assess the prevalence of diseases major rice-growing areas and characterise pathogens associated with infected plants. During survey, rice plants at seedling grain-filling stage showing water-soaked, elongated, light brown lesions leaf margins tips (Figure 1) were collected along grains a polythene bag, labelled sealed. Leaves...

sterilisation there is a risk of infection. Diabetics commonly keep their syringes in spirit although similar practices have been abandoned in hospital, where sterile instruments are now stored dry. It would seem logical for diabetics to store their syringes-glass or plastic-in the same way. Thirty patients reported by Greenough et a13 used a single plastic syringe, stored dry in a domestic ref...

military surgery. Whatever view we choose to take of the explanation of the antiseptic efficiency of Carrel's method, the fact remains that he has shown that infected wounds?early or late?can be sterilised by the means he has devised, and no greater tribute can be paid to the successful results so obtained than the words of a printed notice which the writer of this review saw on the walls in M....
