Longitudinal quantification of brain changes due to development, aging or disease plays an important role in the filed of personalized-medicine applications. However, due to the temporal variability in shape and different imaging equipment and parameters, estimating anatomical changes in longitudinal studies is significantly challenging. In this paper, a longitudinal Magnetic Resonance(MR) brain image segmentation algorithm proposed by combining intensity information and anisotropic smoothness term which contain a spatial smoothness constraint and longitudinal consistent constraint into a variational framework. The minimization of the proposed energy functional is strictly and effectively derived from a fast optimization algorithm. A large number of experimental results show that the proposed method can guarantee segmentation accuracy and longitudinal consistency in both simulated and real longitudinal MR brain images for analysis of anatomical changes over time.

New insights into the aetiology of anaemia in athletes have been discovered in recent years. From hemodilution and redistribution, which are thought to commit to so-called "sports anaemia," to iron deficiency triggered by higher requirements, dietary requirements, decreased uptake, enhanced losses, hemolysis, and sequester, to genetic factors of different types of anaemia (some related to sport), anaemia in athletes necessitates a careful and multisystem methodology. Dietary factors that hinder iron absorption and enhance iron bioavailability (e.g., phytate, polyphenols) should be considered. Celiac disease, which is more common in female athletes, may be the consequence of an iron deficiency anaemia that is unidentified. Sweating, hematuria, gastrointestinal bleeding, inflammation, and intravascular and extravascular hemolysis are all ways iron is lost during strength training. In training, evaluating the iron status, particularly in athletes at risk of iron deficiency, may work on improving iron balance and possibly effectiveness. Iron status is influenced by a healthy gut microbiome. To eliminate hemolysis, athletes at risk of iron deficiency should engage in non-weight-bearing, low-intensity sporting activities.

In recent years, the image processing mechanisms are used widely in several medical areas for improving earlier detection and treatment stages, in which the time factor is very important to discover the disease in the patient as possible as fast, especially in various cancer tumors such as the liver cancer. Liver cancer has been attracting the attention of medical and sciatic communities in the latest years because of its high prevalence allied with the difficult treatment. Statistics indicate that liver cancer, throughout world, is the one that attacks the greatest number of people. Over the time, study of MR images related to cancer detection in the liver or abdominal area has been difficult. Early detection of liver cancer is very important for successful treatment. There are few methods available to detect cancerous cells. In this paper, an automatic approach that integrates the intensity-based segmentation and k-means clustering approach for detection of cancer region in MRI scan images of liver.

Nonketotic hyperglycinemia (NKH) is a rare metabolic brain disease caused by deficient activity of the glycine cleveage system. Localized proton MR spectroscopy (echo-time 166 msec), performed in an infant with the typical clinical and biochemical features of neonatal NKH, showed a markedly increased peak intensity at 3.55 ppm, which was assigned to glycine. Serial proton MR spectrosocpic studies indicated that glycine/choline and glycine/total creatine ratios correlated closely with the patient's clinical course. Proton MR spectroscopy was useful for the non-invasive detection and monitoring of cerebral glycine levels in this infant with NKH.

The purpose of this study is to determine whether the clinical activity of patients with atopic dermatitis(AD) correlate with their serum cytokine levels. 86 patients with AD were treated with KHS, YMH and GHT. On each visit to the clinic, their skin status was evaluated using the SCORAD index and serum IL-4, $IFN-{\gamma}$, IL-12, IL-13, IL-2 and IL-10 were measured by ELISA. After oral administration of herbal medicine, patients' skin status and subjective parameters such as pruritus and sleeplessness were significantly improved according to regression analysis. In particular, patients aged 0-9 showed stronger responses to treatment, which implies that the younger patients aged, the easier the treatment by herbal formula became. In analysis of the type of chosen herbal medicines, YMH treated group showed a stronger response in reduction of affected lesion, intensity of a lesion and subjective symptoms, while KHS treated group showed the least reduction. The levels of serum IL-4, $IFN-{\gamma}$ and IL-2 correlated with disease activity. Moreover, in patients under 0-9, the IL-4 level had a corrleation with disease activity; patients under 10-19 showed a correlation between the levels of IL-4 and IL-2 and disease activity; patients under 20-29 showed a correlation between the levels of IL-2, IL-12 and $IFN-{\gamma}$ and disease activity. In comparison with chosen herbal medicines, the groups treated with YMH or GHT treated group showed a correlation between the levels of IL-4, IL-12 and IL-2 and disease activity while KHS treated group did not. Our data suggest that serum levels of IL-4 and IL-13 are good indicators of clinical improvement in treating AD.

Newcastle disease (ND) is a highly contagious infection of poultry, Two pathology-based techniques, in situ RT-PCR and in situ hybridization (ISH) were applied to formalin-fixed, paraffin-embedded tissues from chickens naturally infected with velogenic ND virus (VNDV). Two pairs of primers and a probe for ISH and in situ RT-PCR, respectively, were selected from highly conserved region of matrix gene of NDV. The ISH experiment was carried out using MicroProbe$^{TM}$ capillary action system within 2 hours. In situ RT-PCR was performed using MicroProbe$^{TM}$ capillary action system and GeneAmp In Situ PCR system. With ISH and in situ RT-PCR, viral nucleic acid was detected in the central nervous system of chickens from infected with neurotropic velogenic Newcastle disease virus (NVNDV), whereas viral nucleic acid was detected in various organs or tissues of chickens from infected with viscerotropic velogenic Newcastle disease virus (VVNDV). In the NVND group, positive signals were characteristically defined in the cytoplasm of neuron, vascular endothelial cells, and perivascular mononuclear macrophages in the central nervous system. One of NVND group, chicken from one farm exhibited positive signals in the bronchial epithelium. The VVND group chickens showed positive reaction in the macrophages, vascular endothelium, and bronchiolar epithelium. Markedly, viral nucleic acid was detected in the macrophages of morphologically normal tissues which were peripheral or located in distant areas from lesions. The central nervous system of chickens infected with VVND virus had positive signals in the vascular endothelial cell, perivascular mononuclear macrophages and some neuron. The number and intensity of the positive cells by in situ RT-PCR were more and stronger, respectively, in comparison with those by ISH. Particularly, positive reaction was detected in macrophages infiltrating in cardiac muscle by in situ RT-PCR, but not obtained by ISH. Therefore, these results demonstrated that ISH is a rapid diagnostic method for detection of NDV and in situ RT-PCR can be used as an efficient method for detection of low viral load infection or subclinical viral infection of NDV.

We investigated the whether endurance exercise and MitoQ intake mediated neuroprotection are associated with mitochondrial function in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine(MPTP) -induced mice model of Parkinson's disease. C57BL/6 male mice were randomly assigned to five groups: Normal Conrol(NC, n=10), MPTP Control(MC, n=10), MPTP +MitoQ(MQ, n=10), MPTP + Exercise(ME, n=10) and MPTP + MitoQ + Exercise(MQE, n=10). Exercise intervention groups performed the treadmill exercise for 5days/week for 5 weeks with gradual increase of intensity. MitoQ intake groups consumed the MitoQ at a concentration of 250μmol by dissolving with water during experiment period. Our data demonstrated that ME and MQE group restored MPTP-induced motor dysfunction. In addition, treatment groups(MQ, ME and MQE) increased tyrosine hydroxylase levels, and suppressed the accumulation of α-synuclein levels. Futhermore, treatment groups modulated the mitochondrial function such as upregulated mitochondrial biogenesis, increased antioxidant enzyme, enhanced a anti-apoptotic protein(e.g., BCL2), and reduced a pro-apoptotic protein(e.g., BAX). Taken together, these results suggested that endurance exercise and MitoQ intake-mediated increase in mitochondrial function contributes to improvement of aggravated dopaminergic neuronal, resulting in attenuation of motor function of Parkinson's disease.

We report a case of Immunoglobulin G4 (IgG4) related disease involving the pterygoplataine fossa. A 83-year-old male presented with left ocular pain and visual disturbance. CT showed an isodense soft tissue lesion in the left pterygopalatine fossa with bony sclerotic changes and erosion. MRI revealed an infiltrative soft tissue mass in the left pterygopalatine fossa as a T2 slightly low signal intensity and heterogeneous enhancement. The patient underwent left ethmoidectomy, and biopsy of the mass was conducted. The histopathological diagnosis was IgG4-related disease. In this case, it was difficult to differentiate invasive aspergillosis, which is common in immunocompromised patients, considering the patient's clinical history of diabetes mellitus. This report describes the imaging findings of IgG4-related disease mimicking invasive sinusitis such as invasive aspergillosis.
