Identification and synthesis of a long-chain antimicrobial peptide from the venom of the Liocheles australasiae scorpion.

Scorpion venom contains linear peptides without disulfide bonds in addition to peptides with disulfide bonds. Many such linear peptides have an amphiphilic α-helical structure, often with antimicrobial activity and can be classified into three groups based on their molecular size. Among them, long-chain antimicrobial peptides consisting of more than 40 residues have not been thoroughly studied due to the difficulty of synthesizing them.

Apraxia of speech due to the left postcentral gyrus lesion.

Key Clinical Message: Apraxia of speech (AOS) due to a postcentral infarction differs from conventional precentral AOS with respect to phonemic errors (phoneme substitution) which are more common than phonetic errors (phoneme distortion) and preserved accent and intonation.

Abstract: Clinical features of apraxia of speech caused by lesions in the postcentral gyrus have not yet been elucidated. Here, we report a patient with this lesion and show how postcentral apraxia of speech differs from the hitherto known precentral apraxia of speech.

Stem water potential estimation from images using a field noise-robust deep regression-based approach in peach trees.

Field-grown peach trees are large and have a complex branch structure; therefore, detection of water deficit stress from images is challenging. We obtained large datasets of images of field-grown peach trees with continuous values of stem water potential (Ψstem) through partial secession treatment of the base of branches to change the water status of the branches. The total number of images as frames extracted from videos of branches was 23,181, 6743, and 10,752, in the training, validation, and test datasets, respectively.

Simultaneous Four Supratentorial Lesions Predict Tube Dependency Due to an Impaired Anticipatory Phase of Ingestion.

This study aimed to identify the neuroanatomical predictors of oropharyngeal dysphagia and tube dependency in patients with supratentorial or infratentorial ischemic strokes. Patients with acute ischemic stroke were enrolled and were classified into 3 groups: right supratentorial (n = 61), left supratentorial (n = 89), and infratentorial stroke (n = 50). Dysphagia was evaluated by a modified water swallowing test and the Food Intake LEVEL Scale to evaluate oropharyngeal dysphagia and tube dependency, respectively.

Disease resistance and growth promotion activities of chitin/cellulose nanofiber from spent mushroom substrate to plant.

Some studies have reported the method for treating the spent mushroom substrate (SMS). However, the effective use as a functional raw material based on properties of SMS remains a formidable challenge. In this study, we investigated the usefulness of SMS in agriculture to develop a new method for treating and utilizing it.
