Laparoscopic minimally invasive gynecologic surgery (MIGS) for benign conditions results in decreased morbidity, and faster recovery, compared with laparotomy. Tissue fragmentation by electromechanical morcellation permits the removal of large specimens through small laparoscopic incisions. Since the US Food and Drug Administration (FDA) published its safety warning about the risk of power morcellators spreading cancer during fibroid surgery in 2014, power morcellation has become rare. MIGS for fibroids and other large tissue specimens has declined...

Dietary partitioning often accompanies the increased morphological diversity seen during adaptive radiations within aquatic systems. While such niche partitioning would be expected in older radiations, it is unclear how significant morphological divergence occurs within a shorter time period. Here we show how differential growth in key elements of the feeding mechanism can bring about pronounced functional differences among closely related species. An incredibly young adaptive radiation of three Cyprinodon species residing within hypersaline lakes in San Salvador Island, Bahamas, has recently been described...

With respect to the benefits of medicinal plants for human health and their use as food, they are extensively being researched and planted in different parts of the world including Iran. Among the most important parameters, which may affect the growth and the yield of medicinal plants is their geographical (ecotype) properties. Accordingly, a research work was proposed to investigate the effects of 10 different regions or ecotypes on the morphological properties of pennyroyal [Mentha longifolia. (L.) Huds.] from the Lamiaceae family in one of the Iranian provinces, namely Ilam...

Differences in risk perceptions of public health and food safety hazards in various poultry husbandry systems by various stakeholder groups, may affect the acceptability of those husbandry systems. Therefore, the objective was to gain insight into risk perceptions of citizens, poultry farmers, and poultry veterinarians regarding food safety and public health hazards in poultry husbandry systems, and into factors explaining these risk perceptions. We surveyed risk perceptions of Campylobacter contamination of broiler meat, avian influenza introduction in laying hens, and altered dioxin levels in eggs for the most commonly used broiler and laying hen husbandry systems in Dutch citizens (n = 2,259), poultry farmers (n = 100), and poultry veterinarians (n = 41)...

Caribbean seagrass habitats provide food and protection for reef-associated juvenile fish. The invasive seagrass Halophila stipulacea is rapidly altering these seascapes. Since its arrival in the Caribbean in 2002, H. stipulacea has colonized and displaced native seagrasses, but the function of this invasive seagrass as a juvenile fish habitat remains unknown. To compare diversity, community structure, and abundance of juvenile fish between H. stipulacea and native seagrass beds, fish traps were deployed in four nearshore bays around St...

Lentil is a major cool-season grain legume grown in South Asia, West Asia, and North Africa. Populations in developing countries of these regions have micronutrient deficiencies; therefore, breeding programs should focus more on improving the micronutrient content of food. In the present study, a set of 96 diverse germplasm lines were evaluated at three different locations in India to examine the variation in iron (Fe) and zinc (Zn) concentration and identify simple sequence repeat (SSR) markers that associate with the genetic variation...

Effector proteins play key roles in the molecular interplay between plants and plant-associated organisms, and effector biology remains one of the most active areas in the research field of molecular plant-microbe Interactions. Using effectors as probes, much has been learned about pathogen virulence and host immunity, which has broad implications in developing disease-resistant crops that are essential for global food security. Thus, the MPMI Editorial Board felt that it is an opportune time to showcase recent progress in this area...

Long-term parenteral nutrition (PN) may be complicated by PN-associated liver disease (PNALD), and some studies suggest an association between the use of soy-based fat emulsions and PNALD development. Patients' liver function typically improves and PNALD resolves after reducing or stopping a soy-based fat emulsion, and thus lipid minimization has been the primary strategy for managing PNALD in many intestinal rehabilitation programs. However, fat emulsions often cannot be stopped entirely, leading some patients to develop PNALD even after lipid reduction strategies have been implemented...

Since early work by Wretlind and Schuberth led to the development of a stable and safe intravenous fat emulsion (IFE) using soybean oil (SO) and egg phospholipid emulsifier, IFEs have become a crucial source of essential fatty acids and nonprotein energy in parenteral nutrition. However, largely due to their high ω-6 polyunsaturated fatty acid (PUFA) and phytosterol content, SO IFEs have been associated with complications, including a proinflammatory profile and hypertriglyceridemia, as well as intestinal failure-associated liver disease...

Obesity has reached epidemic proportions in many developed countries as Western dietary patterns have been widely adopted. These diets are characterized by excess energy intake as well as regular consumption of processed or "fast" foods and limited consumption of fruit, vegetables, and whole grains. The result is a high intake of saturated fat, refined carbohydrates, and sodium; and a low intake of fiber, vitamins, and other phytochemicals. This type of poor-quality diet has been associated with increased risk of chronic inflammatory diseases, including asthma...

BACKGROUND: Heterocyclic aromatic amines (HAAs) have been considered as carcinogenic and mutagenic chemicals generated during thermal processing of protein-rich foods which can be inhibited by some flavonoids. And free radical scavenging is a major characteristic of flavonoids. RESULTS: The half maximal inhibitory concentration (IC50 ) values of nine flavonoids were determined by evaluating their capacity to inhibit 2-amino-3,8-dimethyl-imidazo[4,5-f]-quinoxaline (MeIQx) and 2-amino-3,7,8-trimethyl-imidazo[4,5-f]-quinoxaline (7,8-DiMeIQx) formation in a model system...
