Non-crystallinity and polymorphism in elemental solids

THIS paper shows a universal correlation of the non-crystalline state with polymorphism in elemental solids. This is demonstrated by a map constructed on a plot of the number of polymorphic forms (NPF) against...

A vitreous Kr·2SiO₂

THERE are many studies^1–7 of the presence of inert gases in glasses. Because they have no electron affinity and high ionisation potentials (12 eV for Xe to 24 eV for He) the solubility of inert gases in glasses h...

Short-range structure for amorphous intertransition metal alloys

Amorphous intertransition metal alloys may be a special class of the glassy state whose short-range structure is random tetrahedral close packing of soft atoms similar to those in the crystalline counterparts....

A New Nickel-Free Cryogenic Steel, 06A1NbCuN, and Its Fracture-Safety Evaluation

Nickel steel has been used extensively by the petrochemical industry since nickel significantly increases the low temperature toughness of steel. However, these steels are expensive and nickel is in short supp...

Cross-Linked Envelopes: Keratinocyte Transglutaminase

Membrane-bound transglutaminase plays a key role in the formation of cross-linked envelopes during keratinocyte terminal differentiation. The enzyme can be solubilized from the particulate fraction of cultured...

Peptide ligand-induced conformation and surface expression of the L^d class I MHC molecule

NEWLY synthesized major histocompatibility complex (MHC) class I molecules in the endoplasmic reticulum are thought to bind peptides of foreign and endogenous antigens^1–4. Several lines of evidence indicate that ...

Activation of BPV-1 replication in vitro by the transcription factor E2

Soluble extracts from uninfected murine cells supplemented with purified viral E1 and E2 proteins support the replication of exogenously added papilloma virus DNA. The E2 transactivator stimulates the binding ...

Intradermal angiogenesis in nude mice induced by human tumor cells or b-FGF

Tumor-induced angiogenesis is a promising target for anti-cancer drugs. However, testing of angiostatic drugs in vivo requires adequate models. Thus, our study was aimed at establishing angiogenesis models in ...

The mitotic feedback control gene MAD2 encodes the α-subunit of a prenyltransferase

THE mad2-l mutation inactivates the cell-cycle feedback control that prevents budding yeast cells from leaving mitosis until spindle assembly is complete¹. The gene product of MAD2 shows significant sequence simi...

Development of Fiber-Containing Non-Expanded Products by Extrusion Cooking Process

Wet soybean residue was directly used as a raw material to mix with starchy and proteinaceous substances to make cereal flakes and wet-type texturized products with a twin-screw extruder. The cereal flakes cou...

Differential effects by the p21 CDK inhibitor on PCNA-dependent DNA replication and repair

IN mammalian cells, DNA damage increases the levels of the nuclear tumour-suppressor p53, resulting in elevated synthesis of p21, an inhibitor of cyclin-dependent kinases (CDK)^1–6. p21 may also directly block DNA...

Identification of a major co-receptor for primary isolates of HIV-1

Entry of HIV-1 into target cells requires cell-surface CD4 and additional host cell cofactors. A cofactor required for infection with virus adapted for growth in transformed T-cell lines was recently identifie...
