The technical difficulties associated with measuring coupled and uncoupled 1H spin signals in the human neck are substantial. Artifacts arising from motion and other instabilities, particularly in the presence of high lipid concentrations, can corrupt metabolite intensity measurements. Shimming can be difficult because of local susceptibility differences, and localization may be compromised when using a PRESS-based sequence, which allows for the prescription of only rectangular volumes of interest that, most likely, will not exactly encompass the lesion. Despite these and other difficulties, it seems that several trends have emerged that may provide impetus for further investigations.. The results show that there was a significant increase in Cho:Cr ratios in lymph node metastases of squamous cell carcinoma as compared with normal muscle tissue. The increased ratios resulted more from a decline of the Cr signal than from an elevation of Cho. Of note is that the mean Cho:Cr value of 2.9 was 71% ...

Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images. This method exploits the susceptibility differences between tissues and uses the phase image to detect these differences. The magnitude and phase data are combined to produce an enhanced contrast magnitude image. The imaging of venous blood with SWI is a blood-oxygen-level dependent (BOLD) technique which is why it was (and is sometimes still) referred to as BOLD venography. Due to its sensitivity to venous blood SWI is commonly used in traumatic brain injuries (TBI) and for high resolution brain venographies but has many other clinical applications. SWI is offered as a clinical package by Philips and Siemens but can be run on any manufacturers machine at field strengths of 1.0 T, 1.5 T, 3.0 T and higher. SWI ...
Although the recent evidence for individual differences in plasticity is quite compelling, the authors are very tentative and cautious in their papers, which I suppose is necessary when youre proposing something new. You dont want to scare anyone off. So they are keen to point out that the evidence is not quite solid as yet, and there is more work to be done.. This line of work is only beginning, and there are many unknowns. Much the same as in priming research, the evidence of the effect is running a little ahead of the understanding of the mechanisms involved, and researchers are unclear on whether differential susceptibility stems mostly from nature or nurture, or on the breadth of the phenomena that it applies to. Having said that, the idea that that the people most susceptible to negative symptoms and experiences might be the people most susceptible to positive symptoms and experiences, is quite a cheerful thought..

Cancer incidence varies markedly by ethnicity and geographic location. Ethnic variation in cancer occurrence has traditionally been ascribed to differences in social, cultural, economic, and physical environments. However, this interpretation of the epidemiologic evidence may need to be revised as a result of new biological evidence and theories of carcinogenesis. Carcinogenesis is now recognized

This inhomogeneity is transient during the measurement. The contributions of the imaging gradients may be eliminated as a source of dephasing through proper design of the measurement process, as described in Chapter 4. 2) where T2M is the dephasing time due to the main field inhomogeneity and T2MS is the dephasing time due to the magnetic susceptibility differences. 3) where MXY max is the transverse magnetization MXY immediately following the excitation pulse.

Are the causes of schizophrenia organic (biochemical/physiological) or functional (resulting from experience)? At the moment, perhaps because of the wide array of newly developed brain-scanning techniques, the organic explanations are far more prominent. However, the best answer may lie in a synthesis of the two points of view. The main theory in practice today is the diathesis-stress model, which merges two different areas of research.. First, some definitions. A diathesis is a predisposition to a particular disease. Stress can be defined as any number of psychological and social factors. So, the diathesis-stress model holds that schizophrenia is the consequence of a stress-activated diathesis or predisposition.. Proposed biological diathesis for schizophrenia includes problems with brain chemistry and/or development. Researchers have found malformed parts of the brain in people with schizophrenia. These biological abnormalities can lead to problems with thinking, speech, behavior, and staying ...
Immune cell activation and differentiation occurs concurrently with metabolic reprogramming. This ensures that activated cells generate the energy and substrates necessary to perform their specified function. Likewise, the metabolic programs among different cells of the immune system vary. By targeting different metabolic pathways, these differences allow for selective regulation of immune responses. Further, the relative susceptibility of cells to a metabolic inhibitor is dictated by their metabolic demands; cellular selectivity is based on demand. Therefore, where differences exist in metabolic pathways between healthy and pathogenic cells, there is opportunity for selective regulation with agents lacking intrinsic specificity. There are now a host of studies demonstrating how inhibitors of metabolism (e.g., glycolysis, glutamine metabolism, and fatty acid oxidation) can regulate immune responses and treat immune-mediated pathogenesis. In this brief review we detail how inhibitors of ...

This study has demonstrated that deficiency of BMPR-II increases susceptibility to PAH induced by serotonin in mice. Although the pulmonary vascular phenotype of BMPR2+/− and wild-type littermates was similar under normoxic or chronic hypoxic conditions, infusion of serotonin increased RVSP, RVH, and pulmonary vascular remodeling in BMPR2+/− mice compared with controls. These data provide the first evidence for cross-talk between the BMP and serotonin pathways, both key systems implicated in the pathogenesis of pulmonary hypertension. Serotonin infusion was associated with a reduction in lung Smad1/5 activation in hypoxic mice. Serotonin inhibited BMP signaling in PASMCs, as evidenced by inhibition of Smad1/5 phosphorylation and inhibition of Id3 transcription. Furthermore, PASMCs isolated from BMPR2+/− mice exhibited a heightened DNA synthesis to serotonin and increased activation of ERK1/2 via O·−2. Moreover, we found that pulmonary, but not systemic, arteries from BMPR2+/− mice ...

Dealing with adolescence and teenage has always remained a problem for parents because of the vulnerability to habit formation, the curiosity to experiment and susceptibility to get easily influenced by peers.
As the organism ages, it exhibits a degree of correlated, recognizable, and predictable changes to its physiology over time. These changes can occur synchronously across multiple tissues and organs. The phenotypic changes of aging occur in a type of concert, rather than in isolation, suggesting the residual participation of the endocrine system in the onset of age-related phenotypes. The demise of the cell thus most often occurs within the context of the simultaneous demise of the whole organism.. Organelles and cellular subtypes also exhibit a differential susceptibility to stress during aging. This preference can result in the consistent advent and spreading of disease across particular subsets and even subcompartments of the cells. Thus age-onset diseases often begin in one distinct tissue before signs of dysfunction spread infectiously along reproducible networks, affecting the physiology of distal tissues in distinct but foreseable patterns. We are trying to understand how the small and ...

One of the more interesting aspects of C. neoformans interactions with the host is the large discrepancy in the incidence of infections in male and female patients, with males having a higher incidence of C. neoformans infection and disease than females. This gender-related difference has been observed in dozens of studies and suggests underlying differences in the interactions of the immune response to C. neoformans infection and differential expression of microbial factors between males and females. We have found differences in the immune response of ex vivo male or female macrophages to C. neoformans, PLoS One, 2013. Currently, we are characterizing gender-specific and microbial factors in clinical isolates to determine which factors are involved in the gender susceptibility difference to C. neoformans.. 2.

We found that this phenomenon was associated with the different susceptibility of human and mouse NK cells to autologous tumour cell-induced NK cell abnormalities (NKCA). The latter includes CD16 down-regulation and NK cell depletion. Induction of NKCA by leukaemia and solid tumour cells was influenced neither by IL2 treatment nor by HLA class I antigen expression, but was abrogated by a 10 day culture. Following a 10 day of PBMCs culture, NK cells became resistant to leukaemia and solid tumor cell induced NKCA but maintained their cytotoxic activity. Actinomycin D restored the susceptibility of long term NK (LTNK) cells to NKCA suggesting that the generation of resistance to NKCA required RNA transcription. TAPI-0, a functional analogue of the tissue inhibitor of metalloproteinases (TIMP) 3 inhibited cancer cell induced NKCA underlying a role for a restricted number of metalloproteinases in the generation of this phenomenon. Finally, we found an association of TIMP3 gene and protein ...
Diets deficient in amino acids -- chemicals that make up proteins -- can significantly increase susceptibility to epileptic seizures in rats, according to a study by researchers at the University of California, Davis. The findings may lead to a betterunderstanding of some of the mechanisms involved with epilepsy in humans.
New Approaches for Chagas Disease Chemotherapy. By Guadalupe García Liñares. The latest advances concerning drug design and chemotherapy development to combat the Chagas disease are discussed. This chapter is based on the metabolic differences between the pathogenic parasite and mammal hosts that led to the progress in the search for novel metabolic pathways in parasites that may be essential for parasites survival but with no counterpart in the host. There is a considerable amount of work in the search of more promising molecular targets for drug design. However, the chemotherapy for this disease remains unsolved. It is based on old and fairly not specific drugs associated with long-term treatments, severe side effects, drug resistance, and different strains susceptibility. Herein, a thorough analysis of selected molecular targets is described in terms of their potential usefulness for drug design. Therefore, rational approaches to the chemotherapeutic control of American trypanosomiasis ...
The overall aim of this review was to assemble the evidence that will help unravel the genetic components underlying differences in response to TB. Research in livestock host variability in response to BTB could deliver genetic markers such as SNPs associated with resistance. Implementation could be by the use of genetic markers associated with TB resistance/susceptibility in existing breeding programmes or even the identification of genetically susceptible sires to avoid their use in high BTB prevalence regions. The latter approach could help to achieve the goal set by Cox et al. (2005) who argued that even modest reduction in the reproduction number of M. bovis in cattle could bring the current epidemic under control.. It is possible that M. bovis and cattle may have reached an evolutionary stalemate, as has been proposed for humans (Muse Davis & Ramakrishnan 2009). While this proposed tolerance of host for pathogen and pathogen for host may well be an example of coevolution to maximize the ...

Author Summary The environment humans inhabit has changed many times in the last 100,000 years. Migration and dynamic local environments can lead to genetic adaptations favoring beneficial traits. Many genes responsible for these adaptations can alter disease susceptibility. Genes can also affect disease susceptibility by varying randomly across different populations. We have studied genetic variants that are known to modify disease susceptibility in the context of worldwide migration. We found that variants associated with 11 diseases have been affected to an extent that is not explained by random variation. We also found that the genetic risk of type 2 diabetes has steadily decreased along the worldwide human migration trajectory from Africa to America.
In this study, women who reported moderate susceptibility to breast cancer were most likely to adhere to mammography screening guidelines. High perceived susceptibility adversely influenced adherence in the total sample, but its influence was stronger among women ages ≥50 years. In contrast, the adverse effect of low perceived susceptibility was found only in women ages 40 to 49 years. These effects of perceived susceptibility were found in relation to time to first screening as well as to nonadherence.. Miller (27) proposed that health beliefs, such as perceived disease susceptibility, have less influence on a health behavior once that behavior is habitually practiced. One reason for the stronger effect of low perceived susceptibility on women ages 40 to 49 years than on women ages ≥50 years may be that mammography screening was a relatively new behavior and may not yet have become a habit for many of the younger women. In addition, during the data collection period of this study, ...
