We have proposed a novel single-snapshot spatial frequency domain imaging method with synchronous three-dimensional (3D) profile correction that addresses the confounding effects of involuntary jitter in tissue under examination and the 3D profile of the tissue on the measurements of optical parameters during in vivo examinations. I. In this scheme, orthogonal composite sinusoidal modulated light is projected onto the tissue to be measured.

Cadmium (Cd) is one of the most toxic and widely distributed heavy metal pollutants, posing a huge threat to crop production, food security, and human health. Corn is an important food source and feed crop. Corn growth is subject to Cd stress; thus, reducing cadmium stress, absorption, and transportation is of great significance for achieving high yields, a high efficiency, and sustainable and safe corn production.

In China, water-saving irrigation is playing important roles in ensuring food security, and improving wheat quality. A barrel experiment was conducted with three winter wheat (Triticum aestivum L.) genotypes and two irrigation pattens to examine the effects of regulated deficit irrigation (RDI) on wheat grain yield, water-use efficiency (WUE), and grain quality.

Article Synopsis
  • Irrigation strategies should be optimized to enhance crop yield and water efficiency; a study examined the impact of alternate vs. conventional furrow irrigation combined with different soil moisture levels on winter wheat.
  • Results indicated that a soil moisture limit of 70% produced the highest harvest index and crop water productivity for both irrigation methods, signifying that moderate water deficits are beneficial for conserving water resources.
  • The findings suggest that while conventional furrow irrigation is best in water-abundant areas, alternate furrow irrigation is more suitable for regions facing water scarcity, promoting effective irrigation management based on local conditions.

Trichothecene mycotoxins, a family of common contaminants on cereal grains, are known to negatively impact human and animal health with adverse effect on food consumption being of particular concern. T-2 toxin has been previously demonstrated to induce anorectic response in several animal species including mouse, rat, rabbit. Although the T-2 toxin-induced anorectic response has been associated with the release of gut satiety hormone, much less is known about the role of neurotransmitter in this response.

Trichothecene mycotoxins commonly contaminate cereal grains and are often linked to human and animal food poisoning. The rapid onset of anorexia is a common hallmark of trichothecenes-induced toxicity. Although the neurotransmitters 5-hydroxytryptamine (5-HT) and substance P (SP) are known to regulate appetite, it remains unknown whether these two neurotransmitters are involved in type A trichothecenes-induced anorectic response.

T-2 toxin, a potent type A trichothecene mycotoxin, is produced by various Fusarium species and can negatively impact animal and human health. Although anorexia induction is a common hallmark of T-2 toxin-induced toxicity, the underlying mechanisms for this adverse effect are not fully understood. The goal of this study was to determine the roles of two gut satiety hormones, glucose-dependent insulinotropic polypeptide (GIP) and Peptide YY (PYY) in anorexia induction by T-2 toxin.

A positive urine pregnancy test (UPT) with adnexal mass in ectopic pregnancy is not the ultimate diagnosis. The incidence of ectopic pregnancy is about 27 per 1000 pregnancies [1]. On average, about 6-16% will present to an emergency department with first-trimester bleeding and abdominal pain [2].

Anorexia is a hallmark of animal and human exposed to T-2 toxin, a most poisonous trichothecene mycotoxins contaminating various cereal grains including wheat, corn and barley. Although this adverse effect has been well characterized in several animal species, the underlying mechanisms are unclear. The goal for this study was to elucidate the roles of two gut satiety hormones, glucagon-like peptide-1 amide (GLP-1) and cholecystokinin (CCK) in T-2 toxin-evoked anorectic response using a mouse anorexia bioassay.
