Associating structural characteristics to immunomodulating properties of carrot rhamnogalacturonan-I fractions.

Carrot rhamnogalacturonan-I (cRG-I) is a polydisperse polysaccharide with molecular weights of 7-250 kDa. Using size exclusion chromatography cRG-I was fractionated and pooled in fractions (PF1-6). All fractions contained the same RG-I monosaccharides and similar glycosidic linkages although in varying relative amounts.

Dextran and levan exopolysaccharides from tempeh-associated lactic acid bacteria with bioactivity against enterotoxigenic Escherichia coli (ETEC).

Soybean tempeh contains bioactive carbohydrate that can reduce the severity of diarrhea by inhibiting enterotoxigenic Escherichia coli (ETEC) adhesion to mammalian epithelial cells. Lactic acid bacteria (LAB) are known to be present abundantly in soybean tempeh. Some LAB species can produce exopolysaccharides (EPS) with anti-adhesion bioactivity against ETEC but there has been no report of anti-adhesion bioactive EPS from tempeh-associated LAB.

Bioprospecting phytochemicals of Rosmarinus officinalis L. for targeting SARS-CoV-2 main protease (M): a computational study.

Context: The persistent spread of highly contagious COVID-19 disease is one of the deadliest occurrences in the history of mankind. Despite the distribution of numerous efficacious vaccines and their extensive usage, the perpetual effectiveness of immunization is being catechized. Therefore, discovering an alternative therapy to control and prevent COVID-19 infections has become a top priority.

Incidental diagnosis of a rare pancreatic plasmacytoma with plasmablastic features.

Multiple myeloma is a plasma cell neoplasm that accounts for 10% of all hematologic malignancies, characterized by malignant proliferation of monoclonal plasma cells in the bone marrow. It predominantly affects men 60 to 70 years of age. Plasmacytoma is a discrete mass of neoplastic monoclonal plasma cells that may be osseous or extramedullary.

Thrombotic Thrombocytopenia Masquerading As COVID-19 Infection.

Thrombotic thrombocytopenic purpura (TTP) is a rare and challenging diagnosis that consists of thrombotic microangiopathy due to complete or severe deficiency of ADAMTS13 protease that can present at any age. It is very important to have a suspicion concerning this disease as mortality can be very high if it goes unnoticed. This case describes a patient that presented with gastrointestinal symptoms and hematuria and was found to have COVID-19 and TTP.

Peripheral Neuropathy: Evaluation and Differential Diagnosis.

Peripheral neuropathy, a common neurologic problem encountered by family physicians, can be classified clinically by the anatomic pattern of presenting symptoms and, if indicated, by results of electrodiagnostic studies for axonal and demyelinating disease. The prevalence of peripheral neuropathy in the general population ranges from 1% to 7%, with higher rates among those older than 50 years. Common identifiable causes include diabetes mellitus, nerve compression or injury, alcohol use, toxin exposure, hereditary diseases, and nutritional deficiencies.

Fatal Superimposed Bacterial Sepsis in a Healthy Coronavirus (COVID-19) Patient.

Coronavirus disease 2019 (COVID-19) is a highly infectious disease caused by the newly discovered coronavirus, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). The novel coronavirus first emerged in Wuhan, China, in December 2019 and has led to a global pandemic. The virus mainly spreads through respiratory droplets from an infected person, but environmental contamination can also act as a source of infection, making social distancing an important key in containing the spread of infection.

Abdominal Pain, an Atypical Presenting Symptom of Granulomatosis with Polyangiitis.

Granulomatosis with polyangiitis (GPA) formerly known as Wegener's granulomatosis, is an anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV). It is an uncommon disease with an estimated prevalence of 3 in 100,000 individuals with an equal distribution in both sexes. It is characterized by necrotizing granulomatous vasculitis that primarily affects the upper and lower respiratory tracts and the kidneys.

Focus on Mental Health During the Coronavirus (COVID-19) Pandemic: Applying Learnings from the Past Outbreaks.

The 2019 novel coronavirus (COVID-19) has gained global attention after it originated from China at the end of 2019, and later turned into pandemic as it affected about 118,000 in 114 countries by March 11, 2020. By March 13, 2020, it was declared a national emergency in the United States as the number of COVID-19 cases, and the death toll rose exponentially. To contain the spread of the disease, the world scientist community came together.

ResultMaps: visualization for search interfaces.

Hierarchical representations are common in digital repositories, yet are not always fully leveraged in their online search interfaces. This work describes ResultMaps, which use hierarchical treemap representations with query string-driven digital library search engines. We describe two lab experiments, which find that ResultsMap users yield significantly better results over a control condition on some subjective measures, and we find evidence that ResultMaps have ancillary benefits via increased understanding of some aspects of repository content.

A dominant negative form of Rac1 affects myogenesis of adult thoracic muscles in Drosophila.

Blocking Rac1 function in precursors of the indirect flight muscle of Drosophila severely disrupts muscle formation. The DLM fibers that develop using larval scaffolds are reduced in number and fiber size, while the DVMs, which develop using founder cells, are mostly absent. These adult muscle phenotypes are in part due to a reduced myoblast pool present at the third larval instar.
