Disordered Carbon Shells Enable Shape Dependent Fluorescence Enhancement in Nanodiamond Quantum Sensors Revealed by Correlative TEM–Fluorescence Microscopy

Advanced Functional Materials, EarlyView.
Molten KNO2 treatment induces a lowrefractive index disordered carbon shell on fluorescent nanodiamonds, enhancing fluorescence emission while preserving spin coherence. Machine learningassisted correlative TEMPL enables direct single‐particle resolution of this enhancement relative to air‐oxidized nanodiamonds of similar morphology, establishing a ...

Toward Stable Multivalent Metal Batteries: Understanding the Interfacial Chemistry for Magnesium and Calcium Metal Anodes

Advanced Functional Materials, EarlyView.
Interphase chemistry governs the stability of multivalent metal batteries. We summarize state‐of‐the‐art developments in calcium and magnesium metal batteries by focusing on the correlation among electrolytes, interphase layers, and the electrochemical performance of corresponding metal anodes.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

Advanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Factor VII deficiency

American Journal of Hematology, 1981
AbstractThis report describes three patients with factor (F) VII deficiency: two adult siblings and an unrelated 5½‐month‐old child who succumbed after several central nervous system (CNS) hemorrhages. This event prompted a review of the literature concerning the incidence and characteristics of intracranial hemorrhage in congenital F VII deficiency.Of

Factor VII deficiency and its treatment in delivery with recombinant factor VII

European Journal of Obstetrics, Gynecology and Reproductive Biology, 2004
The authors present two cases of pregnant women with coagulation disorders--one with inherited deficiency of factor VII and the second with chronic hepatitis. Both cases were successfully treated with recombinant activated factor VII of coagulation (NovoSeven) in delivery. The advantages of using this product are discussed.

Congenital factor VII deficiency

The Journal of Pediatrics, 1971
Summary A case of factor VII deficiency in a PuertoRican boy is described. He presented with epistaxis as the only symptom. The importance of early diagnosis of the defect is stressed. Identification of heterozygous carriers is also of importance because these persons, for unknown reasons, might present with hemorrhagic diathesis.

Congenital factor VII deficiency

The Indian Journal of Pediatrics, 2004
A 1(1/2)-month-old baby with seizures, lethargy and refusal of feeds was diagnosed to have intracranial hemorrhage due to factor VII deficiency. MRI also demonstrated the unusual presence of a hemorrhagic infarct. The case underscores the importance of carrying out neuroimaging and appropriate hematological studies even in the absence of obvious ...

Acquired and Isolated Deficiencies in Factor VII

Clinical Laboratory, 2022
Acquired and isolated deficiencies in FVII are exceptional. They have mainly been reported during states of severe sepsis by the presence of proteases destroying the factor or neoplastic pathologies by the presence of an inhibitor. Consequently, very few cases have been published.We report two cases of isolated and acquired deficiency of factor VII due

Congenital deficiency of factor VII

The Indian Journal of Pediatrics, 1996
A case of congenital factor VII deficiency in a five-year-old child is reported. The patient, born of a non-consanguineous marriage, presented with repeated bouts of epistaxis since childhood. The prothrombin time (PT) was markedly prolonged with a normal bleeding time (BT), partial thromboplastin time with Kaolin (PTTK) and platelet count. The patient

Factor VII deficiency and pregnancy

International Journal of Gynecology & Obstetrics, 1989
Hereditary factor VII deficiency is very rare in pregnancy (one in 500,000). However, obstetricians should consider this diagnosis whenever the prothrombin time is prolonged while the activated partial thromboplastin time is normal. The factor VII level increases in normal pregnancy, but the effect of pregnancy upon the factor VII level in deficient ...
