The yields of ethylene from endogenous and exogenous 1-aminocyclo-propane-1-carboxylic acid (ACC) in avocado (Persea Americana Mill.) fruit pedicel extracts were very low when assayed by the method of Lizada and Yang (1979 Anal Biochem 100: 140-145). Addition of phenolic...

Hypervigilance, Allostatic Load, and Migraine Prevention: Antibodies to CGRP or Receptor.

Neurology and therapy

Blumenfeld A, Durham PL, Feoktistov A, Hay DL, Russo AF, Turner I.
PMID: 34076848
Neurol Ther. 2021 Dec;10(2):469-497. doi: 10.1007/s40120-021-00250-7. Epub 2021 Jun 02.

Migraine involves brain hypersensitivity with episodic dysfunction triggered by behavioral or physiological stressors. During an acute migraine attack the trigeminal nerve is activated (peripheral sensitization). This leads to central sensitization with activation of the central pathways including the trigeminal...

Hormonal activity in detached lettuce leaves as affected by leaf water content.

Plant physiology

Aharoni N, Blumenfeld A, Richmond AE.
PMID: 16660015
Plant Physiol. 1977 Jun;59(6):1169-73. doi: 10.1104/pp.59.6.1169.

The interrelationship between water deficiency and hormonal makeup in plants was investigated in detached leaves of romaine lettuce (Lactuca sativa L. cv. ;Hazera Yellow'). Water stress was imposed by desiccating the leaves for several hours in light or darkness...

BACKGROUND: To assess the main causes leading to childhood visual impairment/blindness in a center for low vision in Israel and to analyze the literature on pediatric blinding diseases in developed countries.METHODS: Retrospective study based on observational case series. Data...

Ethylene and the annona flower.

Plant physiology

Blumenfeld A.
PMID: 16659063
Plant Physiol. 1975 Feb;55(2):265-9. doi: 10.1104/pp.55.2.265.

The annona (Annona hybrida) flower is protogynous, and reaches its male stage about 26 hours after the beginning of the female stage. A rise in ethylene production was found to precede the male stage. Much more ethylene was produced...

Cytokinin Activity in Avocado Seeds during Fruit Development.

Plant physiology
