Agar, a major component of the cell wall of red algae, is an interesting heteropolysaccharide containing an unusual sugar, 3,6-anhydro-L-galactose. It is widely used as a valuable material in various industrial and experimental applications due to its characteristic gelling and stabilizing
Rhamnus prinoides (gesho) is an evergreen shrub from East Africa traditionally used for the treatment of illnesses including atopic dermatitis, ear, nose and throat infections, pneumonia, arthritis, brucellosis, flu, indigestion and fatigue.Several of the The mechanical stability of biocatalyst particles in bioreactors is of crucial importance for applications of immobilized-cell technology in bioconversions. The common methods for evaluation of the strength of polymer beads (mostly force-to-fracture or tensile tests) are, however, not yet proven to
The mechanical stability of gels applied for entrapment and retention of biocatalysts in bioreactors is of crucial importance for successful scale-up applications. Gel abrasion in agitated reactors will depend on liquid shear, bubble shear, and wall shear, as well as collisions between the gel
In natural cartilage, collagen fibers form the extracellular matrix, while aggrecan entangles with these fibers and provides cartilage with its osmotic properties, which are critical to resist cyclic compressive loads. In this paper, a hydrogel was fabricated via the entanglement of a bio-inspired
Ralstonia pickettii, formerly known as Burkholderia pickettii, is a non-fermentative gram-negative bacillus. It is emerging as an opportunistic pathogen both in the hospital setting and in the environment, leading to outbreaks especially in the intensive care units. The available literature revealed
The Omnicon FAS II image analysis system was applied to counting tumor colonies grown in a soft agar human tumor clonogenic assay with a detailed protocol designed to assess the instrument's sensitivity, specificity, precision, and accuracy. Comparisons of technician and instrument counts were done
Okinawa prefecture is well known as an endemic area of Strongyloides stercoralis infection, and its recent infection rate was reported 6.2%, which was investigated by a new technique to detect S. stercoralis, agar plate method. Traditional treatment with thiabendazole was temporarily effective for
A 49-year-old woman with a Mycobacterium fortuitum bloodstream infection, who has been managed with central venous (CV) catheterization for two years, was reported. She had undergone rectectomy for rectal cancer and gastectomy for stomach cancer at the ages of 36 and 42, respectively. Also, she had
BACKGROUND
Bartonella henselae is a zoonotic, alpha Proteobacterium, historically associated with cat scratch disease (CSD), but more recently associated with persistent bacteremia, fever of unknown origin, arthritic and neurological disorders, and bacillary angiomatosis, and peliosis hepatis in
Background: Rat bite fever is a systemic febrile illness caused by infection with the Gram-negative bacillus Streptobacillus moniliformis following a bite, scratch, or contact with excrement. Only 26 cases of native valve endocarditis
BACKGROUND
Cats appear to be the primary reservoir host for Bartonella koehlerae, an alpha Proteobacteria that is most likely transmitted among cat populations by fleas (Ctenocephalides felis). Bartonella koehlerae has caused endocarditis in a dog and in one human patient from Israel, but other
In this article, we report the case of a 16-month-old German boy who was admitted to the Children's Hospital of Stuttgart with a 4-week history of intermittent fever, decreased appetite, weakness, fatigue, and difficulty sleeping. He was healthy at birth and remained so for the first 15 months of
A generalized Rayleigh-Plesset-type bubble dynamics model with a damage mechanism is developed for cavitation and damage of soft materials by focused ultrasound bursts. This study is linked to recent experimental observations in tissue-mimicking polyacrylamide and agar gel phantoms subjected to
Mycoplasma sp. are well recognized as etiological agents of respiratory and sexually transmitted disease. Mycoplasma penetrans, a species of Mycoplasma sp., has been frequently detected in HIV-positive patients and associated with the progression of HIV-associated disease. To date,
