    Gastrointestinal helminthiasis in developing countries contributes to malnutrition and anemia. Diagnosis and treatment of helminthiasis, especially with low worm load is an unmet public health need in such settings. The infection may sometimes become manifest when a second pathology leads to purgation of the gastrointestinal tract. Two cases of helminthiasis are presented in which the infections only became amenable to diagnosis due to acute diarrhoea caused by giardiasis and lactulose administration. In the first case, acute giardiasis revealed Ascaris lumbricoides infestation, and in the second case primary helminthiasis (strongyloidiasis) was revealed by lactulose, and also led to Vibrio cholera bacteremia. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes

    Atherosclerosis could be induced in animal model (Rattus novergicus) by feeding atherogenic diet consist of standart feed, cholesterol 2 % from yolk, 5 % goat fat, 0,2% cholic acid and induction with vitamin D3. The goal of this research was to analyze histopathological of thoracic aorta on male Rattus novergicus strain wistar after fed atherogenic diet for 8 weeks. This research was an experimental laboratory research with post test only with control design. Twelve male rats were segregated into two groups (n=6) labelled as control fed standart and atherogenic fed group. After 8 weeks thoracic aorta was taken and histological slides were made and colored with hematoxylin eosin and then measured with atherosclerosis score. The result showed that in atherogenic group there are macrophage, foam cell, and intracellular lipid accumulation with 100% percentage, extracellular lipid accumulation 33,33% (for a little extracellular lipid) and 66,67 (a lot of extracellular lipid) while control group there are macrophage, foam cell, and intracellular lipid accumulation with 33,33% percentage. The statistical test result show there is significant difference between control group and atherogenic group (p=0,003). As conclusion, there is significant difference between control group and atherogenic group

    Superfield Approach to (Non-)local Symmetries for One-Form Abelian Gauge Theory

    Full text link
    We exploit the geometrical superfield formalism to derive the local, covariant and continuous Becchi-Rouet-Stora-Tyutin (BRST) symmetry transformations and the non-local, non-covariant and continuous dual-BRST symmetry transformations for the free Abelian one-form gauge theory in four (3+1)(3 + 1)-dimensions (4D) of spacetime. Our discussion is carried out in the framework of BRST invariant Lagrangian density for the above 4D theory in the Feynman gauge. The geometrical origin and interpretation for the (dual-)BRST charges (and the transformations they generate) are provided in the language of translations of some superfields along the Grassmannian directions of the six (4+2) 4 + 2)-dimensional supermanifold parametrized by the four spacetime and two Grassmannian variables.Comment: LaTeX file, 23 page

    The difficulties in the communication between the deaf and normal people through sign language can be overcome by implementing deep learning in the gestures signal recognition. The use of the Convolution Neural Network (CNN) in distinguishing radar-based gesture signals of deaf sign language has not been investigated. This paper describes the recognition of gestures of deaf sign language using radar and CNN. Six gestures of deaf sign language were acquired from normal subjects using a radar system and processed. Short-time Fourier Transform was performed to extract the gestures features and the classification was performed using CNN. The performance of CNN was examined using two types of inputs; segmented and non-segmented spectrograms. The accuracy of recognising the gestures is higher (92.31%) using the non-segmented spectrograms compared to the segmented spectrogram. The radar-based deaf sign language could be recognised accurately using CNN without segmentation

    The maximum force of skeletal muscle exhibits circadian variation that is associated with time-of-day differences in athletic performance. We investigated whether the diurnal difference in force is associated with the post-translational state of muscle proteins. Twenty physically active men (mean ± SD; age 26.0 ± 4.4 y, height 177.3 ± 6.8 cm, body mass 75.1 ± 8.2.8 kg) completed 5 familiarisation sessions where-in they practiced all maximal efforts. Thereafter they performed experimental sessions, in the morning (08:00 h) and evening (17:00 h), counterbalanced in order of administration and separated by at least 72 h. Rectal, skin, muscle temperatures and ratings of perceived effort measurements where made after the subjects had reclined for 30 min (rest) and after the 5-min cycle ergometry warm-ups and prior to the measurement of knee extensor maximal voluntary isometric contraction (MVIC; including twitch-interpolation) and peak rate of force development (RFD). Data handling: 10 subjects from the cohort of 20 volunteered for muscle biopsy procedures, hence only their data is reported for temperature, MVIC and RFD to align with proteomic analyses. Samples of vastus lateralis were collected immediately after exercise and were analysed by ‘top-down’ and ‘bottom-up’ proteomic methods. Rectal and muscle temperatures were higher at rest in the evening (mean difference of 0.51°C and 0.69°C; p<0.05) than in the morning. MVIC force in the evening was significantly greater than in the morning (mean difference of 67 N, 9.3%; p<0.05), similarly peak RFD (mean difference of 1080 N/s, 15.3%; p<0.05) was improved in the evening. 2D gel analysis encompassed 122 proteoforms and discovered 6 statistically significant (p<0.05; false discovery rate [FDR] = 10%) diurnal differences. Phosphopeptide analysis identified 1,693 phosphopeptides and detected 140 phosphopeptides from 104 proteins that were more phosphorylated (p<0.05, FDR=22%) in the morning vs. evening. Myomesin 2, muscle creatine kinase and the C-terminus of titin, exhibited the most robust (FDR<10%) diurnal differences. In summary, the effects of time of day where seen in measures of rectal and muscle temperature and muscle performance. Exercise in the morning, compared to the evening, coincided with greater phosphorylation of M-band-associated proteins in human muscle. These protein modifications may alter M-band structure and disrupt force transmission, thus potentially explaining the lower force output in the morning
