BACKGROUND In the intensive care unit we have observed that patients have different adherence to 2 commonly used positive-expiratory-pressure (PEP) therapy devices: the PEP bottle and the PEP mask. The reason for this difference is not clear. METHODS In a randomized prospective study, we made continuous recordings of airway pressure and airflow, with 20 healthy volunteers, with the PEP bottle...

The heterogeneity of a pepsin extract of type-24 M protein (pep M24) was demonstrated by absorption of type-specific and cross-reactive human antisera with M protein fragments and heterologous serotypes of M proteins, pepsin extract of type-5 M protein (pep M5) and pepsin extract of type-6 M protein (pep M6). 2 of 12 individuals immunized with pep M24 developed significant rises in antibody tit...

1. Rat liver mitochondria oxidizing malate produce PEP (phosphoenolpyruvate) without the addition of ATP or other nucleotides. 2. The addition of oligomycin in the presence of 2,4-dinitrophenol did not abolish PEP formation and in some instances stimulated its formation. 3. Formation of PEP was inhibited by arsenate. 4. Arsenite decreased PEP formation and caused accumulation of pyruvate. 5. Ad...

Tiêm mao F18 đóng vai trò quan trọng giúp Enterotoxigenic Escherichia coli (ETEC) bám vào ruột và tiết độc tố gây bệnh tiêu chảy heo con sau cai sữa (post-weaning diarrhea, PWD). Vaccine là một cách thức hữu hiệu, kinh tế khả thi phòng chống ETEC trên heo. Việc phát triển vaccine uống, tạo miễn dịch niêm mạc thông qua nhắm trúng đích bào M đang được tâm. Nhiều nghiên cứu cho thấy Hsp60 có năng ...

Plastid-encoded RNA polymerase (PEP) regulates the expression of chloroplast genes involved in photosynthesis and development rice. The PEP-associated protein (PAP) PAP7/pTAC14 is essential for formation PEP complex. However, function PAP7 rice remains unclear. In this study, we identified a mutant, w81, which displays yellow-green leaf symptom before four-leaf stage. seedlings w81 mutant displ...

background: the rabies is one of the most important officially-known viral zoonotic diseases for its global distribution, outbreak, high human and veterinary costs, and high death rate and causes high economic costs in different countries of the world every year. the rabies is the deadliest disease and if the symptoms break out in a person, one will certainly die. however, the deaths resulting ...
