hemorrhoids/tyrosine

Whitish precipitations in three samples of raw cured ham, which appeared in the stereomicroscope as piles of crystals, were confirmed as tyrosine crystals. Tyrosine is readily soluble in nitric acid (yellowish discoloration) and, after addition of potash lye, it precipitates as yellow-orange

A new locus required for type 4 pilus biogenesis by Pseudomonas aeruginosa has been identified. A pilE mutant, designated MJ-6, was broadly resistant to pili-specific phages and unable to translocate across solid surfaces by the pilus-dependent mechanism of twitching motility (Twt-). Immunoblot

One of the most abundant phenolic compounds traced in olive tissues is hydroxytyrosol (HT), a molecule that has been attributed with a pile of beneficial effects, well documented by many epidemiological studies and thus adding value to products containing it. Strong antioxidant capacity and

The cell membrane receptor ErbB-2 migrates to the nucleus. However, the mechanism of its nuclear translocation is unclear. Here, we report a novel mechanism of its nuclear localization that involves interaction with the transport receptor importin beta1, nuclear pore protein Nup358, and a host of

Cancer cells obtained from human hepatocellular carcinoma nodules were subjected to primary culture, and a hepatoma cell line was established. The cell clumps obtained by needle puncture were plated directly in plastic tissue culture flasks without any cell dissociation procedures. Cell clusters

The pathogenic Neisseriae Neisseria meningitidis and Neisseria gonorrhoeae, initiate colonization by attaching to host cells using type IV pili. Subsequent adhesive interactions are mediated through the binding of other bacterial adhesins, in particular the Opa family of outer membrane proteins.

OBJECTIVE Lung cancers harboring common EGFR mutations respond to EGFR tyrosine kinase inhibitors (TKI), whereas exon 20 insertions (Ins20) are resistant to them. However, little is known about mutations in exon 18. METHODS Mutational status of lung cancers between 2001 and 2015 was reviewed. Three

Young leaves of Manihot esculenta Crantz (Euphorbiaceae), Abelmoschus esculentus (Malvaceae), Hibiscus acetosella (Malvaceae) and Pteridium aquilinum (Dennstaedtiaceae) are currently consumed as green vegetables by peoples in sub-Saharan Africa, Latin America, Asia and their migrants living in
