    Abstract: Increased levels of vitamin D and calcium may play a protective role in colorectal cancer (CRC) risk. It has been suggested that these effects may be mediated by genetic variants of the vitamin D receptor (VDR) and the calcium sensing receptor (CASR). However, current epidemiologic evidence from European populations for a role of these genes in CRC risk is scarce. In addition, it is not clear whether these genes may modulate CRC risk independently or by interaction with blood vitamin D concentration wild-type bb, the BB genotype of the VDR BsmI polymorphism was associated with a reduced risk of CRC [RR, 0.76; 95% confidence interval (CI), 0.59-0.98). The association was observed for colon cancer (RR, 0.69; 95% CI, 0.45-0.95) but not rectal cancer (RR, 0.97; 95% CI, 0.62-1.49). The Fok1 and CASR genotypes were not associated with CRC risk in thisand level of dietary calcium intake. A case-control study was conducted nested within the European Prospective Investigation into Cancer and Nutrition. CRC cases (1,248) were identified and matched to 1,248 control subjects. Genotyping for the VDR (BsmI: rs1544410; Fok1: rs2228570) and CASR (rs1801725) genes was done by Taqman, and serum vitamin D (25OHD) concentrations were measured. Conditional logistic regression was used to estimate the incidence rate ratio (RR). Compared with the study. No interactions were noted for any of the polymorphisms with serum 25OHD concentration or level of dietary calcium. These results confirm a role for the BsmI polymorphism of the VDR gene in CRC risk, independent of serum 25OHD concentration and dietary calcium intake.

    Abstract: The immune system works through leukocytes interacting with each other, with other cells, with tissue matrices, with infectious agents, and with other antigens. These interactions are mediated by cell-surface glycoproteins and glycolipids. Antibodies against these leukocyte molecules have provided powerful tools for analysis of their structure, function, and distribution. Antibodies have been used widely in hematology, immunology, and pathology, and in research, diagnosis, and therapy. The associated CD nomenclature is commonly used when referring to leukocyte surface molecules and antibodies against them. It provides an essential classification for diagnostic and therapeutic purposes. The most recent (8th) Workshop and Conference on Human Leukocyte Differentiation Antigens (HLDA), held in Adelaide, Australia, in December 2004, allocated 95 new CD designations and made radical changes to its aims and future operational strategy in order to maintain its relevance to modern human biology and clinical practice

    Notes: Summary Different methods of quantifying thermal alliesthesia were used to examine the circadian variations of thermal comfort. At eight different times of the 24 h day, four subjects were exposed to a constant room temperature of 25°C. After 30 min rest, the subjects performed 50 W bicycle ergometer work for 45 min. A 5 s temperature stimulus of 15°, 20°, 25°, 30°, 35°, and 38°C was applied on the hand, forehead, and back of the neck. For each stimulus the subjects voted their degree of thermal comfort on the subjective thermal comfort scale, ranging from +2 for very pleasant to −2 for very unpleasant. The most pleasant temperature on the back of the neck was chosen by voluntary control. This procedure was performed at the start and repeated every 15 min throughout the exposure time. A 5:5 × 2.7 cm2 Peltier thermode was used to give the temperature stimuli. Voluntary control voting was carried out using the temperature control knob without looking at the temperature scale of the thermode. The results suggest that during rest in a state of thermal neutrality the core temperature is about 0.06°C lower than the thermoregulatory set point (Cabanac et al. 1976; Strempel et al. 1976). This deviation (Trect - Tset) from the set point is known in man-made servo-systems as the load error (Benzinger 1979). During rest in an atmosphere of thermal comfort, the “load error” in the human thermostat is found to be negative (Cabanac et al. 1976; Strempel et al. 1976; Benzinger 1979), i.e., Tset 〉 Trect, where Trect is the prevailing core temperature and Tset, is the thermoregulatory set point. The small deviation from the set point is viewed as being necessary to sustain the response and to keep the temperature in equilibrium between production and loss of heat (Benzinger 1979). Thermal comfort limits during work rise from the early morning to the afternoon and then fall slowly towards the minimum level in the morning. The circadian variations of the core temperature load error associated with onset of sweating have a phase shift of 180° (12 h) with the alliesthesial reactions. Using our results and the results from Cabanac et al. (1976), it has been possible to write a circadian thermoregulatory set function to estimate the set point at any point of day time.

    Notes: Summary The degree of pleasantness or unpleasantness of thermal sensation aroused by a particular peripheral thermal stimulus has been shown to be an indicator of thermal state of the body in relation to the thermoregulatory set point. This phenomenon is known as thermal alliesthesia. The quantification of thermal alliesthesia was possible using two methods: (1) A set of temperature stimuli (15, 20, 25, 30, 35, and 38
