Comparative analysis of primary and secondary metabolites in wheat seedlings (Triticum aestivum L.) cultivated under varying photosynthetic photon flux densities and growth periods

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND To elucidate the impact of environmental factors on the nutritional quality of metabolites in wheat seedlings, both primary and secondary metabolites must be comprehensively examined. We thus conducted a comparative analysis of these metabolites in wheat seedlings grown under various photosynthetic photon flux densities (PPFD) (200,

Gold Laser Cricopharyngeal Myectomy for Cricopharyngeal Dysfunction

open access: yesThe Laryngoscope, EarlyView.
Endoscopic treatment for cricopharyngeal bar with or without diverticulum has become the preferred option in management. However, critics cite high recurrence rates. This study evaluated a modified endoscopic approach of cricopharyngeal myectomy, removing a block of tissue with a Gold laser, to treat 84 patients with CP bar, demonstrating significantly

In Situ Impact of Waste Polyethylene (PE) Films on Soil Quality and Plant Growth in Agricultural Soil

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Plastic films have accumulated in soil ecosystems over decades of agricultural activities. These films potentially disrupt the soil structure, hinder nutrient cycling, and deteriorate soil quality. However, there is still a substantial knowledge gap in understanding how real‐world waste polyethylene films (WPEFs), with varied shapes and sizes,

Seasonal patterns of phytoplankton photoacclimation in a dimictic oligotrophic lake over 5 yr: Implications for chlorophyll as an estimate of biomass

open access: yesLimnology and Oceanography, EarlyView.
Abstract Chlorophyll a is commonly used as a surrogate for algal biomass in lakes and oceans even though phytoplankton can readily adjust intracellular chlorophyll concentration to changes in the environment through a cellular process termed photoacclimation.
