Although diverse signaling events are initiated by stimulation of multichain immune recognition receptors on lymphocytes, it remains unclear as to which specific signal transduction pathways are functionally linked to granule exocytosis and cellular cytotoxicity. In the case of natural killer (NK) cells, it has been presumed that the rapid activation of protein kinase C (PKC) enables them to me...

Low HDL-cholesterol (HDL-C) levels may elevate atherosclerosis risk, and often associate with hypertriglyceridemia (HTG); however, the metabolic causes of low HDL-C levels with or without HTG are poorly understood. We studied the turnover of radioiodinated HDL apolipoproteins, apo A-I and apo A-II, in 15 human subjects with low HDL-C, six with normal plasma TG levels (group 1) and nine with hig...

BACKGROUND The aim of this study was to use mathematical modeling to identify and quantify the main factors that affect daily feed intake (DFI) and feed conversion ratio (FCR) in grow-finishing (GF) pig units. We evaluated the production records of 93 GF farms between 2010 and 2013, linked to a company, working in a cooperative system, located in western Paraná State, Brazil. A total of 683 bat...

Interaction between the previously obtained dominant negative mutant, referred to as fcr (T. Matano, T. Odawara, M. Ohshima, H. Yoshikura, and A. Iwamoto, J. Virol. 67:2026-2033, 1993), and the wild-type envelope proteins (Env) of Friend murine leukemia virus was examined. The wild-type Env was bound to the fcr mutant Env and trapped in the endoplasmic reticulum. The virus receptor was not invo...

Fear of cancer recurrence (FCR) involves anxiety about the possible return or progression disease. It is common among people surviving cancer, covering a range adaptive and maladaptive responses including clinical presentations FCR, for which different psychological interventions have been developed, most within cognitive-behavioural paradigm. Recently, emotion-focused therapy (EFT) has propose...

The broiler birds after experimental challenge with virulent MAS reovirus developed infection. This infection resulted into poor body weights, uneven growth, poor FCR, poor BPEI and poor PEI. The uninfected birds showed uniform live weights, even growth, better FCR, better BPEI and better PEI. The group with reovirus infection resulted into economic loss while uninfected group resulted into pro...

Antibody agonists targeting tumor necrosis factor (TNF) superfamily receptors, including CD40, are being tested therapeutically as anticancer agents. Studies in mice have shown that anti-CD40 monoclonal antibody (mAb) requires Fc-receptor (FcR) engagement to activate antitumor immunity. In contrast, we have reported that clinically active anti-human CD40 mAb CP-870,893 does not require FcR cros...

BACKGROUND Bone mineral density (BMD) is used as a sole parameter in the diagnosis of osteoporosis. Due to the ease of acquirement of BMD, clinical diagnosis still involves its usage although the limitations of BMD are quite well-established. Therefore, this preliminary study hoped to reduce the errors introduced by BMD alone by incorporating geometric and structural predictors simultaneously t...

We studied the relationships among levels of acid cholesteryl esterase (ACE) activity in kidney, liver, and aorta and clearance of I-labeled human low density lipoprotein (LDL) from the circulation. The premise was that levels of ACE (which is involved in the hydrolysis of the cholesteryl esters of LDL) might correspond to the rate at which LDL was removed from the circulation, or fractional ca...

CONTEXT Apolipoprotein (apo) C-III is associated with hypertriglyceridemia and progression of cardiovascular disease. Plasma apoC-III is elevated in centrally obese men, and we hypothesized that the kinetics of apoC-III are disturbed in these subjects. OBJECTIVE We developed a compartmental model to determine very low-density lipoprotein (VLDL) and high-density lipoprotein (HDL) apoC-III meta...
