Selective eliminating lignin together with sea salt chlorite to boost the product quality as well as de-oxidizing activity of xylo-oligosaccharides from lignocellulosic bio-mass.
The time to haemostasis did not differ significantly between the 2 devices (5.6 ± 1.0 vs. 5.3 ± 0.7 minutes;
= 0.118). Multivariable logistic regression analysis showed a lower risk of ASC with the InnoSEAL pad (adjusted OR, 0.174; 95% CI 0.034-0.890;
= 0.036).

No major ASC was seen with either pad, and no significant difference of minor ASC was observed between 2 pads.

Special emphasis has been placed on the role of cardiac magnetic resonance imaging (CMR) for the assessment of morphological and functional consequences of different stages of HCM including prognostication. The text is illustrated with the images and data of the HCM patients diagnosed with CMR study in our hospital. CMR is an important tool, particularly relevant in novel risk factors and LV dysfunction groups. The HCM group with overt left ventricular dysfunction is underrecognized, often labelled by clinicians as dilated cardiomyopathy. Advanced diagnostic and management strategies effectively influence the natural history of HCM.
To evaluate the role of "penumbra sign", diffusion-weighted imaging (DWI), and the apparent diffusion coefficient (ADC) value in differentiating tubo-ovarian abscess (TOA) from ovarian malignancy.

Thirty-six patients with 50 adnexal masses (tubo-ovarian abscess,
= 24; ovarian malignancy,
= 26), who underwent magnetic resonance imaging (MRI) with DWI, were retrospectively evaluated. "Penumbra sign" (hyperintense rim on T1W images), diffusion restriction, and mean apparent diffusion coefficient (ADC) values from cystic (c-ADC) and solid (s-ADC) components were evaluated for all the masses.

"Penumbra sign" on T1W images was significantly more common in the TOA group (
= 21, 87.5%) than in the ovarian malignancy group (
= 2, 7.7%) (
< 0.001). Similarly, diffusion restriction in the cystic component was more frequent in the TOA group (
= 24, 100% vs.
= 2, 10.5%;
< 0.001). In contrast, diffusion restriction in the solid component was more common in the ovarian malignancy group (
= 5, 20.8% vs.
= 26, 100%;
< 0.001). The mean c-ADC value was significantly lower in TOAs (
< 0.001). A c-ADC value of 1.31 × 10
mm
/s may be an optimal cut-off in distinguishing TOAs from ovarian malignancies. Conversely, the mean s-ADC value was significantly lower in the ovarian malignancy group (
< 0.001). An s-ADC value of 0.869 × 10
mm
/s may be an optimal cut-off in differentiating ovarian malignancies from TOAs (
< 0.001). ROC curve analysis showed that c-ADC values had a higher diagnostic accuracy than s-ADC values.

"Penumbra sign" on T1W images, diffusion characteristics, and ADC values provide important clues in addition to conventional MR imaging features in differentiating TOA from ovarian malignancy.

Long-haul COVID-19 is a condition of unknown background occurring in COVID-19 survivors regardless of the severity of the SARS-CoV-2 infection itself. The aim of the study was to evaluate brain changes in patients suffering from variable symptoms of brain fog after COVID-19.

Eleven patients hospitalized due to symptoms of severe brain fog, i.e. insomnia, sudden impairment of cognitive function, headache, and depression, and 14 healthy volunteers underwent brain imaging including MR spectroscopy.

Routine MR imaging revealed no specific macroscopic changes in keeping with brain fog. Considering that the clinical manifestation of brain fog is transient, the evaluation of the metabolic status of the brain remained the method of choice. The concentration of the major cerebral metabolites, i.e. NAA, Cho, and Cr, remained stable. However, changes in Glx and Lac concentration were observed in MR spectroscopy.

Following results along with clinical course of the brain for imply probable ischaemic background of symptoms.

She visited our emergency room because of chest pain. She finally underwent emergency percutaneous coronary intervention in right coronary artery due to acute coronary syndrome. Several months later, she complained of exertional chest pain again. Exercise-stress electrocardiogram showed ST-segment depression in V2-V6. https://www.selleckchem.com/products/AZD1480.html However, coronary angiography showed no organic stenosis and we conducted acetylcholine provocation test. We finally detected severe coronary artery spasm and diagnosed exercise-induced vasospastic angina (VSA). This case highlights the importance of the recognition of exercise-induced VSA. Exercise-induced VSA needs the definite diagnosis and appropriate treatment. Learning objective Many patients felt chest pain even if they have undergone percutaneous coronary intervention (PCI). This case highlights the importance of the recognition of exercise-induced vasospastic angina (VSA). Exercise-induced VSA needs definite diagnosis and appropriate treatment. This case report describes the importance of precise diagnosis and highlights the recognition of exercise-induced VSA. We recommend the acetylcholine provocation test after PCI in order to determine the diagnosis of exercise-induced VSA.We describe a case of immunoglobulin G4-related lung disease presenting as chronic pulmonary hypertension with involvement of right pulmonary artery and superior vena cava. Immunoglobulin G4- related disease is a rare systemic sclerosing disease with autoimmune entity that causes fibrotic, often mass-like manifestations that variably affect different organ systems and can be mistaken with other disorders. Timely diagnosis requires awareness on the part of clinicians and pathologists as well as radiologists to the variable manifestations of this newly recognized disorder. .Optical coherence tomography (OCT) can visualize calcification of the coronary plaque as a low-intensity lesion with sharp borders. However, residual lipid tissue inside the calcification could pose a problem in plaque evaluation by OCT. We present a case of acute coronary syndrome (ACS) demonstrating plaque rupture in the calcified plaque. In this case, OCT demonstrated a cavity suspected to represent rupture in the calcified plaque and near-infrared spectroscopy revealed a lipid component behind the calcified plaque. Although calcified plaque is not considered a reason for ACS except for calcified nodules, residual lipid tissue inside the calcification might cause ACS if the thin fibrous cap over the lipid tissue is disrupted, even if surrounded by calcification. .The treatment of digital ulcer (DU) in systemic sclerosis (SSc) has not been established. A 77-year-old female with a refractory DU in SSc on the right foot was transferred to our hospital. Wound healing had not been achieved despite several endovascular treatments (EVT) and minor amputations. We started Waon therapy 5 days per week as an adjunct therapy. She was placed in a far-infrared-ray dry sauna maintained at 45 °C for 15 min, and was subsequently kept to rest with soothing warmth using a blanket for additional 30 min outside the room. Gradually, the wound had become smaller and the skin perfusion pressure (SPP) had increased. The increase of the blood flow to the wound could be observed in the angiogram on day 109. An additional EVT on day 109 also accelerated wound healing. Finally, wound healing was completely achieved without additional amputations on day 173. In this presented case, Waon therapy contributed to increase of the blood flow to the wound, evidenced by SPP value. Waon therapy may serve as an effective adjunct therapy of DU in SSc. .Optimal timing of open-heart surgery for the treatment of patients with cerebral hemorrhage remains controversial because systemic heparinization may lead to catastrophic bleeding. Several recent reports have shown that patients who undergo open-heart surgery .within a few weeks of cerebral hemorrhage have a much lower risk of exacerbated bleeding than previously considered. Herein, we report a case of left atrial myxoma and large hemorrhagic embolic stroke, which was successfully operated on with no exacerbation of cerebral hemorrhage. Careful assessment of time-course changes in cerebral hemorrhage by neurological imaging and adjustment of anticoagulation can help prevent the exacerbation of postoperative cerebral hemorrhage and neurological deterioration. .Calcified amorphous tumor is a rare intracavitary cardiac lesion and an accompanying infection is extremely rare. A 76-year-old woman was transferred to our hospital because of cerebral infarction. Echocardiography and chest computed tomography showed a calcified large mobile mass on the posterior mitral valve that was diagnosed with a calcified amorphous tumor. Moderate aortic regurgitation and severe mitral regurgitation were also confirmed. Her blood culture detected Gamella sp. We surgically dissected this infective calcified amorphous tumor. The border between this infective tumor and the mitral annulus was unclear because of severe infection and necrotic tissue. After careful complete resection, the healthy ventricular muscle was exposed and we performed annular reconstruction with bovine pericardial patches. And we replaced the aortic and mitral valves using bioprosthesis. While weaning from cardiopulmonary bypass, however, left ventricular rupture occurred twice. Despite successful repair of left ventricular rupture, which controlled bleeding, she died from multi-organ failure on postoperative day 6. An infective calcified amorphous tumor in such a critical case has not been reported previously. The calcified amorphous tumor probably become serious when the infection occurred. In this situation, the utmost caution should be paid to the patient. .Acquired coarctation of the aorta (CoA) following total aortic arch replacement (TAR) is a rare complication inducing left ventricular (LV) dysfunction probably due to increased LV afterload and secondary hypertension caused by increased upper body and decreased renal blood flow. We describe a case of a 35-year-old male who developed atypical CoA with severe LV dysfunction with LV ejection fraction of 10%, but without secondary hypertension after TAR using conventional elephant trunk (ET) technique for acute aortic dissection. Computed tomography revealed near-occlusive CoA due to narrowed distal ET. Because the myocardial histological findings were mild, and he had no cardiac failure history, we determined that LV function might be reversible. He underwent thoracic endovascular aortic repair (TEVAR), resulting in restored LV function. However, as the descending aortic false lumen distally to the end of ET was rapidly dilated, probably due to increased cardiac output and lower body blood flow, he underwent descending aortic replacement 3 months after TEVAR.
