The addition of D-glucose, D-galactose, or D-mannose to culture medium increased survival of heated Chinese hamster ovary cells in a concentration- and time-dependent manner. Heat protection by sugars was not immediate but required prior incubation in the sugar medium before hyperthermia. The degree
We have examined the relative ability of 16 sugars and sugar analogues to reduce cell killing by hyperthermia of 40 min, 45 degrees C. In general, sugars were added to the culture medium 6 h prior to heating at a concentration of 100 mM (400 mosmol). The results show that D-hexoses, L-hexoses,
Salmonella typhi 5076-1C, a potential live, oral vaccine for protection against typhoid fever and Shigella sonnei shigellosis, expresses the S. sonnei form I antigen and normal S. typhi somatic antigens. Polysaccharide antigens of this galactose epimeraseless genetic derivative strain were hot
A total of 21 cases of laboratory-acquired typhoid fever associated with teaching and proficiency tests occurred in the United States during a 33-month period, prompting a search for less virulent strains of S. typhi which would be suitable for teaching purposes. Two strains were evaluated which are
Lavandula angustifolia was used to treat flus and fevers, joint swelling and pain in Uighur medicine. This study aimed to investigate antioxidant, antit anti-inflammatory and antalgic noids content (530.1mg/g rutin/g dry extract) with stronger DPPH scavenging abilities and reduciactivities of total
We develop paclitaxel (PTX) and magnetic nanoparticles (MNPs) coencapsulated, surface charge-switchable, thermosensitive poly(d,l-lactic-co-glycolic acid)-l-lysine-d-galactose (PTX-MNP-PLGA-Lys-Gal) NPs for the controlled release of the anticancer drug. The novel dual signal-responsive nanovehicle
Acetaminophen (APAP) is commonly used to relieve pain and fever in a clinical setting, but its excessive use can lead to serious hepatotoxicity. Our previous study demonstrated that polydatin (PD) can effectively attenuate d-galactose- and alcohol-induced hepatotoxicity, however, its effect on
