Propolis is beeswax with rich bioactive compound content. On the market, there many propolis products as food supplements for consumers. This study aimed to investigate effect of supplement based on at several concentrations viability baby hamster kidney cells and murine macrophage cell lines (BHK-21 RAW 264.7). For this purpose, both were treated two-fold serial dilutions (from 20 2-10) each s...

Sulfation of glycosaminoglycans and giycopeptides was com pared in baby hamster kidney (BHK) cells and the polyoma virus transformants (PY-BHK). Cells were incubated with | fH ]glucosamine and pSJsulfate, and the labeled glycosaminoglycans and giycopeptides were isolated by digesting the cell membrane fraction with pronase followed by gel filtration. Each type of giycosammoglycan in the void vo...

Tyrosyl kinase activity in vesicular stomatitis virus (VSV) acquired from host cells that differ in morphology was investigated. VSV grown in baby hamster kidney (BHK) cells with rounded morphology and a high efficiency of colony formation in soft agar (Rous sarcoma virus [RSV]-transformed and suspension BHK cells) was compared with VSV grown in BHK cells with a flattened morphology and lower e...

The alterations in complex-type N-linked oligosaccharides that can occur when an animal cell line is transformed by two dissimilar viruses were examined by comparing the N-linked oligosaccharides of baby hamster kidney (BHK) cells, metabolically radiolabeled with [2-’H]mannose, to the same class of oligosaccharides from BHK cells separately transformed by Rous sarcoma virus (RS-BHK), an RNA ret...

A cDNA clone for factor 10 (FX) isolated from chicken embryo inserted into the mammalian cell expression vector pCDNA3.1 was transfected into the baby hamster kidney (BHK-21) cell line. The generated BHK-21 cells with inducible expression of FX were used to investigate the efficacy of the serine transmembrane protease to proteolytic activation of influenza virus hemagglutinin (HA) with monobasi...

Although murine coronaviruses naturally infect only mice, several virus variants derived from persistently infected murine cell cultures have an extended host range. The mouse hepatitis virus (MHV) variant MHV/BHK can infect hamster, rat, cat, dog, monkey, and human cell lines but not the swine testis (ST) porcine cell line (J. H. Schickli, B. D. Zelus, D. E. Wentworth, S. G. Sawicki, and K. V....

The typical elongated bipolar morphology of baby hamster kidney (BHK) cells is not shown by polyoma-transformed BHK (Py-BHK) cells. Instead, the transformed line adheres poorly to tissue-culture plastic and cells have a more rounded morphology than the parent line. Plasma fibronectin is known to mediate the spreading of BHK cells, but when human serum is subjected to Sephacryl S-300 chromatogra...

Objectives: This study aimed at analyzing the test-retest and interrater reliabilities of the Test of In-Hand Manipulation-Modified (TIHM-M), as well as the relationship between in-hand manipulation and handwriting. Methods: We administered the TIHM-M twice, two days apart, and the Beknopte Beoordelingsmethode voor Kinder Handschriften (BHK) - Concise Assessment Method for children’s handwriti...

The BHK interpretation of logical constants is analyzed in terms of a systematic account given by Prawitz, resulting in a reformulation of the BHK interpretation in which the assertability of atomic propositions is determined by Post systems. It is shown that the reformulated BHK interpretation renders more propositions assertable than are provable in intuitionistic propositional logic. Mints’ ...

Protein kinase activities were measured in Rous sarcoma virus-infected baby hamster kidney (BHK) cells that express v-src (BHK [v-src]) and compared with those of revertant and control BHK cells. We observed about a fivefold-higher tyrosine phosphorylating activity in BHK (v-src) cell extracts, which was due to src but not other cellular tyrosyl kinase activities since preincubation with anti-s...
