Difficult Airway Management in a Patient With Nicolaides-Baraitser Syndrome Who Had a Small Jaw and Limited Mouth Opening.

Nicolaides-Baraitser syndrome (NCBRS) is a rare congenital genetic disorder characterized by distinctive facial features similar to Treacher Collins syndrome (TCS). We report the first case of successful nasal fiberoptic intubation in a patient with NCBRS with micrognathia and limited mouth opening due to trismus. A 9-year-old girl with NCBRS and dental caries was scheduled to undergo general anesthesia for a dental extraction.

SPECC1L regulates palate development downstream of IRF6.

SPECC1L mutations have been identified in patients with rare atypical orofacial clefts and with syndromic cleft lip and/or palate (CL/P). These mutations cluster in the second coiled-coil and calponin homology domains of SPECC1L and severely affect the ability of SPECC1L to associate with microtubules. We previously showed that gene-trap knockout of Specc1l in mouse results in early embryonic lethality.

In vitro effect of gelatins on murine cell proliferation.

Porcine skin (PS) gelatin suppressed proliferation of a murine hepatic cell carcinoma cell line, MH134, a murine fibrosarcoma cell line, Meth A and a murine T cell lymphoma cell line, RL Male 1. The magnitude of suppression of the proliferation by cold water fish skin (CWFS) or bovine bone (BB) gelatin was lower than that by PS gelatin. On the other hand, BB gelatin stimulated proliferation of murine spleen cells.

Tumor cell growth-inhibiting effect of melanoidins extracted from miso and soy sauce.

Melanoidins, a group of plant-produced melanins, were extracted from miso and shoyu (soy sauce), which are products of soybeans and widely consumed as food in oriental countries. The molecular weight of these melanoidins was approximately 5600 as revealed by Sepharose CL-4B column chromatography. The melanoidins were cultured together with HCT-15 cells derived from human colon carcinoma and AGS cells derived from human gastric carcinoma.

Direct tumor growth suppressive effect of melanoidin extracted from immunomodulator-PSK.

Melanoidin, which belongs to the melanin group of molecules, was extracted from the polysaccharide biological response modifier PSK. Melanoidin was cultured together with HCT-15 cells derived from human colon cancer and with AGS cells derived from human gastric carcinoma. After four days of culture, cell count was compared with that of the control cells.

Anti-tumor effect of methanol extracts from red and white wines.

Crude methanol extracts of red and white wines were added to diethyl ether in order to divide them into the anthocyanin fraction (insoluble in diethyl ether) and fractions containing other flavonoids and their derivatives (soluble in diethyl ether). However, the white wine did not contain anthocyanins (all of the methanol extract was soluble in diethyl ether). When HCT-15 cells, derived from human colon cancer or AGS cells, derived from human gastric cancer, were cultured with these fractions, the anthocyanin fraction from the red wine and the non-anthocyanic substances extracted from red and white wines suppressed the growth of the cells, and the suppression rate by the anthocyanin fraction was significantly higher than that of the other fractions.

Effect of gold on survival of tumor-bearing mice.

Sodium aurothiomalate (monogold monosodium mono-hydrogen sulfidobutanedioate), an anti-rheumatoid gold agent, was injected s.c. every other day for three times or given in drinking water daily for two weeks to Balb/C mice that were inoculated with syngeneic Meth/A cells i.

Inhibition of cell growth in culture by quinones.

Quinones were studied for their growth inhibitory effect on cultured malignant cells. HCT-15 cells derived from human colon carcinoma were used for these experiments. Quinones used were arbutin in the benzoquinone group, juglone and lawsone in the naphthaquinone group, alizarin, emodin, 1,8-dihydroxyanthraquinone, and anthraquinone in the anthraquinone group, and xanthone.

Effect of gold on tumor-associated antigens.

A gold compound, which is an anti-rheumatoid agent, was clinically applied to patients showing a high level of tumor-associated antigens. Two patients showed no clear evidence of recurrence except for a high level of tumor-associated antigens. The gold compound was injected i.

Tumor cell growth suppression by tannic acid.

Tannic acid was cultured together with tumor cells that had originated from human malignant tumors (HCT-15 & AGS). Significant suppression of tumor growth was observed. The 50% suppression was observed at the concentration between 50 micrograms/ml and 12.

Effect of allomelanin on tumor growth suppression in vivo and on the cell cycle phase.

Allomelanins are nitrogen-free macromolecular polymers of simple phenols produced by higher plants and fungi. In an earlier work we found that allomelanins were effective in suppressing the growth of cultured tumor cells. In the present study we examined the effect of these polymers on the survival curve of Balb/C mice inoculated i.

Tumor cell growth suppression by chalcone (1,3-diphenyl-2-propen-1-one).

Chalcone or 1,3-diphenyl-2-propen-1-one which is widely distributed in higher plants and is considered to be a precursor of all flavonoids, was studies in terms of its anti-tumor growth activity in vitro and in vivo. Mice given the chalcone, which was suspended in the drinking water, showed a statistically significant rise in percent survival: 66% at the 35th day for the chalcone-treated animals vs. 30% for the control ones.

Suppression of growth of cultured malignant cells by allomelanins, plant-produced melanins.

Allomelanins, which belong to the melanins produced by higher plants and fungi, were studied with respect to their growth suppressive effects on cultured HCT-15 cells derived from human intestinal carcinoma and Meth/A cells derived from a Balb/C mouse lymphoma. Allomelanins were extracted from black soy beans and black sesame seeds with 0.2% NaOH in water.

Influence of OH group and sugar bonded to flavonoids on flavonoid-mediated suppression of tumor growth in vitro.

Many flavonoids extracted from higher plants, synthesized or purified flavonoids, and their aglycones showed anti-tumor activity. Using purified or synthesized flavonoids, we studied the effect of the chemical structure of 2-benzoic flavone on the growth of human tumor cells (HCT-15 in vitro. The type of sugar combined with the A phenol of flavonoids played an important role in the tumor suppression; i.

Flavonoid-mediated tumor growth suppression demonstrated by in vivo study.

Many of flavonoids as well as bioflavonoids extracted from higher plants, which were earlier revealed to have tumor cell growth suppression activity in vitro, were examined for their effect on tumors in vivo. Balb/c mice were inoculated i.p.

Suppression of tumor cell growth by anthocyanins in vitro.

Bioflavonoids, extracted from flower petals, were examined for their growth inhibitory effect on cells in culture. They were found to significantly suppress the growth of the cultured cells. Anthocyanins tended to show greater inhibitory effect than other flavonoids.
