  • The increasing popularity of traditional Chinese herbal medicine highlights the need for accurate methods to authenticate Chinese Materia Medica (CMM).
  • This study introduces a new denoising filter and chord length distribution (CLD) technique to classify starch grains in microscopic images.
  • Results from analyzing 240 starch grains across 24 classes demonstrate that this method is more effective and efficient than existing approaches, which rely on circular size distribution and require greater computational resources.

Article Abstract

As tradition Chinese herbal medicine becomes increasingly popular, there is an urgent need for efficient and accurate methods for the authentication of the Chinese Materia Medica (CMM) used in the herbal medicine. In this work, we present a denoising filter and introduce the use of chord length distribution (CLD) for the classification of starch grains in microscopic images of Chinese Materia Medica. Our simple denoising filter is adaptive to the background and is shown to be effective to remove noise, which appears in CMM microscopic starch grains images. The CLD is extracted by considering the frequency of the chord length in the binarized starch grains image, and we shall show that the CLD is an efficient and effective characterization of the starch grains. Experimental results on 240 starch grains images of 24 classes show that our method outperforms benchmark result using the current state-of-the-art method based on circular size distribution extracted by morphological operators at much higher computational cost.

Glutinous and japonica sorghum can be applied to different production processes by their amylopectin content and starch structure. However, the differences in the fine structure and physiochemistry properties of their starches, as well as their fermentation properties remain unclear. Compared with japonica sorghum, glutinous sorghum has a higher amylopectin content, short amylose chain content, relative crystallinity, and ∆H, but lower setback (SB), and starch granule size.

A molecular module improves rice grain quality and yield at high temperatures.

Natl Sci Rev

State Key Laboratory of Rice Biology and Breeding, China National Center for Rice Improvement, China National Rice Research Institute, Hangzhou 310006, China.

Excessive temperatures during grain filling can compromise endosperm starch biosynthesis and decrease grain quality and yield in rice. However, the molecular mechanisms underlying these remain unclear. Here, we show that heat shock protein OsHsp40-1 interacts with and elevates the ATPase activity of OsHsp70-2 in rice.

Diet quality components and gut microbiota of patients on peritoneal dialysis.

J Ren Nutr

January 2025

Division of Nephrology Universidade Federal de São Paulo, São Paulo, Brazil; Nutrition Program, Universidade Federal de São Paulo, São Paulo, Brazil. Electronic address:

Objective: To evaluate the associations between the quality of the diet and its components and microbial diversity and composition in peritoneal dialysis (PD) patients.

Design And Methods: This crossectional study included PD patients for at least 3 months, aged 18-75 years and clinically stable. The Diet Quality Index (DQI), validated for the Brazilian population, is based on the energy density of 11 components ("sugar and sweets"; "beef, pork and processed meat"; "refined grains and breads"; "animal fat"; "poultry, fish and eggs"; "whole cereals, tubers and roots"; "fruits"; "non-starch vegetables"; "legumes and nuts"; "milk and dairy products"; "vegetable oil").

Shaanxi Union Research Center of University and Enterprise for Grain Processing Technologies, College of Food Science and Engineering, Northwest A&F University, Yangling 712100, Shaanxi, PR China. Electronic address:

This study aimed to probe the influence of amylose in starch granules on starch modification. Part of the amylose from sorghum starch was removed through warm water leaching, and the samples were then microwaved. The effects of treatments on starch structure, physicochemical properties, and digestibility were researched.

Molecular Mechanisms of Grain Chalkiness Variation in Rice Panicles.

Plants (Basel)

January 2025

Rice Research Institute, Anhui Academy of Agricultural Sciences, Hefei 230031, China.

Grain chalkiness adversely affects rice quality, and the positional variation of grain chalkiness within a rice panicle presents a substantial obstacle to quality improvement in China. However, the molecular mechanism underlying this variation is unclear. This study conducted a genetic and physiological analysis of grains situated at distinct positions (upper, middle, and bottom primary branches of the rice panicle, denoted as Y1, Y2, and Y3) within a rice panicle using the Yangdao 6 variety.
