Flight capacity and behavior of Ephestia kuehniella (Lepidoptera: Pyralidae) in response to kairomonal and pheromonal stimuli.

Flight behavior is an important component to understand in the context of pest management. However, because of their small size, little is known about the flight capacity of most stored-product insects, and when a flight has been assessed, it usually consists of a propensity for initiating flight. Despite a priori expectations of the importance of flight for moths, there are no data about the flight capacity and little on the flight behavior of the Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae).

Gene editing improves endoplasmic reticulum-mitochondrial contacts and unfolded protein response in Friedreich's ataxia iPSC-derived neurons.

Friedreich ataxia (FRDA) is a multisystemic, autosomal recessive disorder caused by homozygous GAA expansion mutation in the first intron of frataxin () gene. FXN is a mitochondrial protein critical for iron-sulfur cluster biosynthesis and deficiency impairs mitochondrial electron transport chain functions and iron homeostasis within the organelle. Currently, there is no effective treatment for FRDA.

Corn360: a method for quantification of corn kernels.

Background: The rapidly advancing corn breeding field calls for high-throughput methods to phenotype corn kernel traits to estimate yield and to study their genetic inheritance. Most of the existing methods are reliant on sophisticated setup, expertise in statistical models and programming skills for image capturing and analysis.

Results: We demonstrated a portable, easily accessible, affordable, panoramic imaging capturing system called Corn360, followed by image analysis using freely available software, to characterize total kernel count and different patterned kernel counts of a corn ear.

Joining Forces: The Addition of a Palliative Care Practitioner to a Resident Teaching Service During COVID-19 Pandemic as a Tool to Improve Patient Care and Provider Communication.

The COVID-19 pandemic has presented an array of novel issues for hospitals and their staff, 1 of the most noted being increased patient isolation due to visitation restrictions. This has created new challenges for health care systems and their workers. To leverage the expertise of Palliative Care Practitioners (PCP) as described here to improve patient/provider communication, patient experience, and quality of care during the COVID-19 pandemic.

Fatty Acid Uptake in Liver Hepatocytes Induces Relocalization and Sequestration of Intracellular Copper.

Copper is an essential metal micronutrient with biological roles ranging from energy metabolism to cell signaling. Recent studies have shown that copper regulation is altered by fat accumulation in both rodent and cell models with phenotypes consistent with copper deficiency, including the elevated expression of the copper transporter, ATP7B. This study examines the changes in the copper trafficking mechanisms of liver cells exposed to excess fatty acids.
