In a two-stage skin tumorigenesis protocol [7,12-dimethylbenz[a]anthracene (DMBA) initiation followed by twice weekly 12-O-tetradecanoylphorbol-13-acetate (TPA) promotion], SENCAR mice developed an average of approximately 8.5 papillomas per animal. Hyperthermia treatments of the initiated skin (44

The present work was designed to examine the effect of in vivo hyperthermia on the cell number and functions of polymorphonuclear leucocytes (PMN) and monocytes in human beings. Eight healthy volunteers were immersed into a waterbath (WI) (water temperature 39.5 degrees C) for 2 h, whereby their

Mild hypothermia impairs resistance to infection and, reportedly, impairs phagocytosis and oxidative killing of unopsonized bacteria. We evaluated various functions at 33 degrees-41 degrees C in neutrophils taken from volunteers. Adhesion on endothelial cells was determined using light microscopy.

Exposure to zinc fume may cause metal fume fever, an acute reaction characterized by an invasion of neutrophils into the airways. This investigation was conducted to examine the possibility that Zn2+ and ZnO might stimulate the formation of oxygen radicals by human neutrophils. Luminol-amplified

Clinical observations and experimental studies have shown that hyperthermia can provoke febrile seizures, which are the most common type of pathological brain activity in children. We previously demonstrated that hyperthermia produced a depression of GABAergic neurotransmission in the hippocampus of

Fever is a hallmark of infections and inflammatory diseases, represented by an increase of 1-4°C in core body temperature. Fever-range hyperthermia (FRH) has been shown to increase neutrophil recruitment to local sites of infection. Here, we evaluated the impact of a short period (1 h) of FRH

The K-562 cell line was treated with the superinduction protocol involving phorbol myristate acetate (PMA) for production of human interleukin 1 (IL-1). The resultant dialyzed K-562 superinduced supernatants contained potent IL-1-like activity when tested in 4 bioassays for IL-1. However, these

OBJECTIVE To investigate the presence of TRAPS (tumor necrosis factor receptor-associated periodic syndrome), which is a recently defined, dominantly inherited autoinflammatory syndrome caused by mutations in the tumor necrosis factor receptor superfamily 1A gene (TNFRSF1A, CD120a), in a Finnish

Large granular lymphocytes (LGL) with a T or natural killer (NK) lymphoblast morphology and indiscriminate (non-major histocompatibility complex-linked) cytotoxicity for a variety of target cells can be derived in culture from the tissues of animals infected with either alcelaphine herpesvirus-1

Rift Valley fever (RVF) virus is a cause of significant human and animal disease in many parts of Africa. In some cases, it causes a hemorrhagic fever, which is frequently fatal. Prior studies have shown that RVF virus productively infects peritoneal macrophages from susceptible rat strains. The

African swine fever virus (ASFV) encodes a homologue of the inhibitor of apoptosis (IAP) that promotes cell survival by controlling the activity of caspase-3. Here we show that ASFV IAP is also able to activate the transcription factor NF-kappaB. Thus, transient transfection of the viral IAP

Familial Mediterranean fever (FMF) is an inherited disease whose manifestations are acute but reversible attacks of sterile inflammation affecting synovial and serosal spaces. The FMF gene (MEFV) was recently cloned, and it codes for a protein (pyrin/marenostrin) homologous to known nuclear factors.

Cytokines stimulate inflammatory defenses against viral infections. In order to evade host defenses, viruses have developed strategies to counteract antiviral cytokines. African swine fever virus (ASFV) is a large, double-stranded DNA virus that infects macrophages. This study demonstrates that ASFV

The brown seaweed Undaria pinnatifida (Harvey) Suringar is used in traditional medicine to treat fever, urination problems, lumps and swelling, and as a dietary supplement for post-childbirth women. We examined the anti-inflammatory activities of the seaweed. The methanol extract of the seaweed was

The diuretic hormone aedeskinin-III is known to increase the paracellular Cl- conductance in Malpighian (renal) tubules of the mosquito Aedes aegypti via a G protein-coupled receptor. The increase serves the blood-meal-initiated diuresis and is associated with elevated levels of Ca2+ and
