CHANGES IN THE INFRARED ATTENUATED TOTAL REFLECTANCE (ATR) SPECTRA OF LIGNINS FROM ALFALFA STEM WITH GROWTH AND DEVELOPMENT

Changes in the infrared attenuated total reflectance (ATR) spectra of lignins from alfalfa stem with growth and development

Lignin is a poorly characterized polymer and its exact properties vary depending on both the species of the plant and its location within the plant.Three classes of lignins taken from alfalfa stem AFTER SUN BALM were examined.The investigation was concentrated on the determination of chemical changes in the lignins during growth and development by

Evidence That Calcium Entry Into Calcium-Transporting Dental Enamel Cells Is Regulated by Cholecystokinin, Acetylcholine and ATP

Dental enamel is formed by specialized epithelial cells which handle large quantities of Ca2+ while producing the most highly mineralized tissue.However, the mechanisms used by enamel cells to handle bulk Ca2+ safely remain unclear.Our previous work contradicted the dogma that Ca2+ is ferried through the cytosol of Ca2+-transporting Gun Safes cells

Periprosthetic femoral fractures in minimally-invasive anterolateral short stem versus transgluteal straight stem cementless total hip arthroplasty: What are the differences in the femoral and pelvic morphology?

Abstract Background The occurrence of periprosthetic femoral fractures (PFFs) in cementless total hip arthroplasty (THA) might be associated with the proximal femoral morphology and the pelvis.PFFs in short stem THA are associated with an increased Canal Flare Index.PFFs in straight stem THA show a decreased Canal Flare Index.Therefore, this study
