The ingesting of raw vegetables plays an important role in the transmission of several infectious diseases due to the high frequency of irrigation with wastewater. The objective of this study was to evaluate the sanitary conditions of all lettuce producing crops in Ribeirão Preto through microbiological and parasitological analysis of both irrigation water and lettuce together with the implanta...

Article history: Received on: 08/11/2012 Revised on: 29/11/2012 Accepted on: 15/12/2012 Available online: 28/01/2013 In this study, assessment of the potential effect of cypermethrin-treated lettuce on the rat liver physiology is carried out. Cypermethrin-treated lettuce and three doses of cypermethrin (CY) were administered during 28 days to rats. Along the experimental period, animal behavior...

The dry deposition to several leafy vegetables (endive, head lettuce, red oak leaf lettuce, spinach) was studied. Particles with attached Cs were used for testing the particulate deposition, gaseous elemental I was the tracer for gas deposition. The particle deposition was the highest for rough and structured leafs as red oak leaf lettuce has, but as well for spinach with many open stomata. The...

To degrade the polysaccharides, wood-decay fungi secrete a variety of glycoside hydrolases (GHs) and carbohydrate esterases (CEs) classified into various sequence-based families of carbohydrate-active enzymes (CAZys) and their appended carbohydrate-binding modules (CBM). Oxidative enzymes, such as cellobiose dehydrogenase (CDH) and lytic polysaccharide monooxygenase (LPMO, formerly GH61), also ...

The potential of fungal pretreatment to improve fermentable sugar yields from wheat straw or Miscanthus was investigated. We assessed 63 fungal strains including 53 white-rot and 10 brown-rot fungi belonging to the Basidiomycota phylum in an original 12 day small-scale solid-state fermentation (SSF) experiment using 24-well plates. This method offers the convenience of one-pot processing of sam...

Hepatitis B virus (HBV) infection is endemic in Asia and chronic hepatitis B (CHB) is a major public health issue worldwide. Current treatment strategies for CHB are not satisfactory as they induce a low rate of hepatitis B surface antigen (HBsAg) loss. Extracts were prepared from lettuce hydroponically cultivated in solutions containing glycine or nitrate as nitrogen sources. The lettuce extra...

In both Basidiomycotina and Ascomycotina, Poly B-411 decolorization was an excellent indicator of the ability to cause white rot: 109 of the 110 isolates of brown rot fungi tested definitely did not decolorize Poly B-411, and 392 of the 401 mainly active isolates of white rot fungi decolorized Poly B-411. The Bavendamm (tannic acid) reaction was a less reliable test: of 74 white rot isolates ex...

The increasing number and proportion of aged individuals in the population warrants knowledge of normal physiological changes of left ventricular (LV) biomechanics with advancing age. LV twist describes the instantaneous circumferential motion of the apex with respect to the base of the heart and has an important role in LV ejection and filling. This study sought to investigate the biomechanics...

Nacrtak Rot is one of the most important defects in timber assortments of Norway spruce (Picea abies). With the aim to investigate this phenomenon, we analyzed 1,334 spruce trees from 65 locations across Slovenia. The study showed that the incidence of rot was higher in even-aged stands compared to uneven-aged stands. Lower-trunk rot (for the purpose of this study, lower-trunk rot is rot that a...
