Miniaturized spectrometers based on graded photonic crystal films.

Miniaturized spectrometers have become increasingly important in modern analytical and diagnostic applications due to their compact size, portability, and versatility. Despite the surge in innovative designs for miniaturized spectrometers, significant challenges persist, particularly concerning manufacturing cost and efficiency when devices become smaller. Here we introduce an ultracompact spectrometer design that is both cost-effective and highly efficient.

Three Licorice Extracts' Impact on the Quality of Fresh-Cut Sweet Potato ( (L.) Lam) Slices.

The quality of fresh-cut produce, particularly sweet potatoes, is crucial for their value. Licorice extract is an optional additive in fresh-cut sweet potatoes. This study examined the impact of three licorice extracts (licorice acid, LA; licorice flavonoids, LF; and licorice polysaccharides, LP) on the quality of fresh-cut sweet potato slices (FCSPSs) for one week of storage.

Effect and Mode of Different Concentrations of Citrus Peel Extract Treatment on Browning of Fresh-Cut Sweetpotato.

Browning is one of the main phenomena limiting the production of fresh-cut sweetpotatoes. This study investigated the anti-browning effect of citrus peel extracts and the key components and modes of action associated with browning in fresh-cut sweetpotatoes. Five different concentrations of citrus peel extract (1, 1.

Development of critical K dilution curves for diagnosing sweetpotato K status.

Scientific and reasonable application of potassium fertilizer is an important agronomic measure to achieve high yield and high quality of sweetpotato, and it is of great significance to determine the appropriate amount of potassium fertilizer in the field. For this we constructing a model of the critical K dilution curve (CKDC) of sweetpotato under different N levels to determine crop nutritional statuses. In this study, a 3-year field experiment was conducted in Zhejiang Province in China, using two nitrogen levels (N0: 0 kg ha and N1: 120 kg ha) and five K fertilization rates (K0: 0, K1: 75, K2: 150, K3: 225, K4: 300 kg ha) for two sweetpotato cultivars of 'Shang 19' and 'Yan 25'.

Genome-wide identification and expression analysis of the polygalacturonase gene family in sweetpotato.

Background: Polygalacturonase (PG), a crucial enzyme involved in pectin degradation, is associated with various plants' developmental and physiological processes such as seed germination, fruit ripening, fruit softening and plant organ abscission. However, the members of PG gene family in sweetpotato (Ipomoea batatas) have not been extensively identified.

Results: In this study, there were 103 PG genes identified in sweetpotato genome, which were phylogenetically clustered into divergent six clades.

Comprehensive Evaluation of Raw Eating Quality in 81 Sweet Potato ( (L.) Lam) Varieties.

The raw eating quality of sweet potato is complex. As consumers start paying more attention to the raw eating quality of tuberous roots in sweet potato, the evaluation of the raw eating quality of sweet potato is becoming an important issue. Therefore, we measured 16 quality indicators in 81 varieties of sweet potato.

Heat stress may cause a significant reduction of rice yield in China under future climate scenarios.

Extreme heat events have become more frequent and severe under climate change and seriously threaten rice growth. Most existing crop models tend to underestimate the impacts of heat stress on rice yields. Heat stress modules in crop models have not been extensively explored, particularly on a large scale.

A New Curve of Critical Leaf Potassium Concentration Based on the Maximum Root Dry Matter for Diagnosing Potassium Nutritional Status of Sweet Potato.

Critical leaf nutrient concentrations have often been used to diagnose the nutritional status of crops. Determining critical leaf potassium (K) concentrations for the maximum root dry matter (RDM) will provide a reliable means of linking leaf K nutrient concentrations to the yield of sweet potato. Three field experiments, using varying K application rates (0-300 kg K ha) and two sweet potato cultivars, were performed in the Zhejiang Province of China.

Changes in cell wall components and polysaccharide-degrading enzymes in relation to differences in texture during sweetpotato storage root growth.

Sweetpotato has special texture characteristics, which directly affect the eating quality and post-production processing quality of sweetpotato. To investigate the texture change mechanism of sweetpotato during the growth process, this study selected two varieties with significant differences in texture from 35 varieties. The storage roots were sampled at 50, 80, 110, and 140 days after planting.

The clinicopathological features and treatment modalities associated with survival of neuroendocrine cervical carcinoma in a Chinese population.

Background: Neuroendocrine cervical carcinoma (NECC) is a rare but aggressive form of cervical cancer representing less than 3% of all cervical cancer cases. The objective of this study is to evaluate the effects of the clinicopathologic features and treatment modalities on the survival of patients with NECC.

Methods: In all, 89 stage I-IV patients with NECC that were diagnosed and treated between 2006 and 2014 at the Zhejiang Cancer Hospital were retrospectively recruited in this study.

Canopy Chlorophyll Density Based Index for Estimating Nitrogen Status and Predicting Grain Yield in Rice.

Canopy chlorophyll density (Chl) has a pivotal role in diagnosing crop growth and nutrition status. The purpose of this study was to develop Chl based models for estimating N status and predicting grain yield of rice ( L.) with Leaf area index (LAI) and Chlorophyll concentration of the upper leaves.

A Model-Based Estimate of Regional Wheat Yield Gaps and Water Use Efficiency in Main Winter Wheat Production Regions of China.

Wheat production is of great importance for national food security and is greatly influenced by the spatial variation of climatic variables, soils, cultivars, etc. This study used WheatGrow and CERES-Wheat models integrated with a GIS to estimate winter wheat productivity, yield gap and water use in the main wheat production regions of China. The results showed that the potential wheat yield gradually increased from south to north and from west to east, with a spatial distribution consistent with the accumulated hours of sunshine.

The clinicopathological and prognostic role of thrombocytosis in patients with cancer: A meta-analysis.

Previous studies have linked the presence of thrombocytosis with the progression and development of cancer; however, this trend requires further investigation. The present study aimed to derive an estimation of the degree of association between thrombocytosis and the 5-year overall survival rate of patients with cancer, as well as common clinicopathological features, by performing a meta-analysis of 20 (n=12,778) published studies. The PubMed and Embase databases were searched systematically for all relevant articles published in English.

The HLA-DQB1 gene polymorphisms associated with cervical cancer risk: A meta-analysis.

Human leukocyte antigens (HLA) alleles may affect the development of cervical cancer through immunologic control of human papillomavirus (HPV). The association between HLA-DQB1 alleles and risk of cervical cancer has been extensively studied, but the results obtained remain inconsistent. To explore a more extensive role of HLA-DQB1 alleles on cervical cancer risk, we carried out a meta-analysis including 4862 cases and 8988 controls from 22 published studies.
