Recently, Korean researchers found that sprouted garlic formed from old garlic bulbs with bright green shoots sprouting from their cloves has higher antioxidant activity than fresher, younger bulbs (177). They observed that garlic sprouted for 5 days had the highest antioxidant activity. Therefore, sprouting may be a useful way to improve the antioxidant potential of garlic (177). Contrary to some sprouted plant foods like potatoes, which are harmful, sprouted garlic makes many new beneficial compounds that may present more health benefits than fresh intact garlic.

The above observations strongly suggest a non-specific origin of neurites in SP and support the suggestions that some of the classical neuritic changes in AD may represent reactive sprouting (Geddes et al, 1985; Hyman et al, 1987; Struble et al, 1987). Early studies (Ramon y Cajal, 1923) described sprouting in experimentally transected axons which resulted in filopodia that resemble SP neurites. In silver stains of tissue from a case of AD, one of us (RGS) identified an axon displaying filopodia along its length, and was able to trace the axon to a SP. The concept of reactive sprouting should raise questions about possible therapies that would induce or support sprouting because over-stimulation of sprouting could paradoxically increase the progression of one of the classic manifestations of the disease.
Dopamine in the Immune and Hematopoietic Systems
Published in Nira Ben-Jonathan, Dopamine, 2020
Angiogenesis is a highly regulated process that takes place through two nonexclusive events of microvascular growth: sprouting or splitting [70]. Sprouting differs from splitting angiogenesis by forming entirely new vessels as opposed to splitting existing vessels. As illustrated in Figure 9.6, sprouting proceeds in several well-characterized stages. First, angiogenic factors [VEGF and fibroblast growth factor (FGF)], released from neighboring cells, bind to their respective receptors on endothelial cells and activate signal transduction pathways. Matrix metalloproteinases (MMPs), produced by the endothelial cells are then activated and degrade the extracellular matrix, enabling an escape of endothelial cells from the parental vessel walls. This is followed by their migration and proliferation. The integrins, expressed by endothelial cells, facilitate their adhesion to the extracellular matrix and the formation of solid sprouts that connect to neighboring vessels. Angiopoietin 1 (Ang-1), binding to Tie-2 receptors, stimulates pericyte recruitment and vessel stabilization. Final vessel maturation and stabilization necessitate additional morphological changes that include lumen formation and perfusion, network establishment, remodeling, and pruning to become full-fledged functional vessels.

During the experiments, daily measurements were done to determine and note the information related to sprouting and plant growth to calculate the level of germination percentage and germination rate (day). At first, tuberose bulbs were sprouted and grown up to 2–3 cm. Then, it was observed that the growth of bulbs treated with high levels of radiation was delayed and then wilted. So, the plants were highlighted as sprouted when the bulbs managed to initiate a flowering stem. The sprouting time was calculated by the following equation (Momeni et al. 2011): Vg represents the sprouting time, n represents the number of sprouted bulbs at each instance, t represents the interim time between two instances of counting, and N represents the total number of sprouted bulbs.

This experiment is a direct validation and serves as a proof of concept that the EMR exposure rate, time and intensity has an adverse effect on the plant tissues. The study shows that the variation in secretion of plant hormones like Gibberellins, Cytokinins, Abscisic Acid and Auxins had led to the retardation in the complete growth of the plant (Naqvi 1999) – (Arteca 1996.). The radiation is mainly due to the antenna present in the gadgets and these radiations will be absorbed by the vegetation. This is measured in terms of SAR for a given tissue. SAR depends upon dielectric property, conductivity, mass density, electric field strength of the tissues etc. The absorption of radiation by pea seeds near to the router is more as it receives more power in the vicinity of the router. So the variation in absorption results in growth retardation even from its initial stage of the germination. This effect in the sprouting stage makes changes in the entire life cycle of each plant community. These continuous exposure reduces the nutrient capability of vegetations and it makes them unhealthy to human life.
Promoting vascularization for tissue engineering constructs: current strategies focusing on HIF-regulating scaffolds

However, HIF-regulating scaffolds alone cannot be the answer to the problem of vascularization as native angiogenic programs are inherently slow with angiogenic sprouting speed ranging from ~60–150 μm per day [14,23,52,146]. Thus, vascularization of thick engineered tissues will require days to weeks. Even in tumors, where angiogenic sprouting is significantly accelerated, vascularization takes days [147]. Notably, it has been shown, that incorporation of vascular cells into engineered tissues decreases the time necessary for vascularization and perfusion after transplantation [23], as do surgical techniques were the highly vascularized omentum is utilized [18–20]. Nevertheless, the native angiogenic program cannot be sufficiently accelerated to catch up with cell death, which occurs as a result of oxygen deprivation within the first days after transplantation [17]. Thus, it appears necessary to combine these pro-vascular strategies with approaches to delay hypoxia-induced cell death or to utilize materials releasing oxygen.
