As a good food supply for the local people in various Senegalese regions, the forest fruits are becoming very important. They are using between foods or main condiment for dishes in many part of Africa. These fruits represent non negligible sources of vitamins, carbohydrates and minerals. Instead of more commercialized species such as Adansonia digitata L., Detarium senegalensis J. F. Gmel., Sa...

Food Chemistry (2009), doi:10.1016/j.foo Açai fruit are native to the Amazon region of South America and two predominant species are commercially exported as fruit pulps for use in food and beverage applications. Detailed characterisation of the polyphenolic compounds present in the de-seeded fruits of Euterpe oleracea and Euterpe precatoria spe...

Juniper (Juniperus communis) is a slowly growing softwood species that has unusually high elasticity. To demonstrate the utilization of the material properties of juniper, conventional kraft pulping was used to prepare juniper pulp, whose handsheet and fiber properties were subsequently analyzed. A large number of uncooked fiber bundles remained after pulping, the screened yield was low, and ka...

The purpose of the investigation was to assess the depth of inf lammatory reactions in the exposed pulps of crown-fractured and ground teeth. Thirty-six incisors in 11 adult monkeys were used for the experiments. In 24 teeth, the pu lp was exposed by grinding or by crown fracture, and the pulpal reactions were examined after 3, 48, and 168 hours. In three-hour specimens, the depth of early chan...

In this study, two biodegradable polymers, polylactic acid (PLA) and polyhydroxybutyrate (PHB), were mixed with short and long fiber pulps using a torque rheometer. PLA/PHB-fiber composites consisting of up to 40 wt% paper pulp were produced through a unique procedure and evaluated using various techniques including thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray dif...

Human immunodeficiency virus (HIV) infection is characterized by the massive infiltration of secondary lymphoid organs with activated CD8(+) T lymphocytes. While converging data indicated that these cells were HIV-specific cytotoxic T lymphocytes (CTLs) responsible for HIV spread limitation, direct evidence was lacking. Here, the presence of HIV-specific effector CTLs was demonstrated directly ...

OBJECTIVE To evaluate the success rate of a calcium hydroxide-based direct capping agent in permanent teeth. METHOD AND MATERIALS A total of 1,075 permanent teeth were treated in this study. All patients received direct pulp capping with a calcium hydroxide-based agent. Inclusion criteria were teeth with healthy pulps, pulps with signs of reversible pulpitis, and a pulp chamber roof opening s...

Extraction of hemicelluloses prior to pulping and conversion of the extracted hemicelluloses to other bioproducts could provide additional revenue to traditional pulp and paper industries. The effect of hemicelluloses pre-extraction with a hydrothermal (HT) process on Pinus radiata chemimechanical pulp (CMP) properties was investigated in this study. The HT extraction resulted in a release of 7...
