Introduction: Mycobacterium paragordonae (MPG) is a novel and uncommon nontuberculous mycobacterium (NTM). We describe a case of MPG pulmonary disease (MPGPD) with a single, rapidly growing, pulmonary mass, which has rarely been reported.

Case Report: A chest CT scan of a 66-year-old woman revealed a rapidly growing solitary mass-like lesion in the upper lobe of the right lung, which was not seen in the previous chest CT scan six months ago.

  • Lactic acid bacteria (LAB) fermentation significantly enhances the antioxidant capacity of mango juice, as shown by the study of three LAB strains: Lactobacillus plantarum NCU116, Lactobacillus acidophilus NCU402, and Lactobacillus casei NCU215.
  • The fermentation process increases polyphenols while decreasing vitamins and carotenoids, highlighting that polyphenols are the primary contributors to improved antioxidant properties.
  • Notably, L. acidophilus NCU402 led to the largest increase in a specific polyphenol (1,2,3,4,6-O-pentagalloylglucose), while L. casei NCU215 was most effective in releasing bound

Bacterial infection severely hinders skin wound healing, highlighting the critical application value of developing antibacterial and anti-inflammatory hydrogel dressings. In this work, we focused on β-glucan from Hericium erinaceus (HEBG) as the research object, and proposed a solvent-induced combined temperature manipulation technique to trigger multilevel self-assembly of β-glucan. Furthermore, we incorporated green synthesized near-infrared photosensitizer tannic acid (TA)/iron (III) complex into the system.

Article Synopsis
  • Natural fungal β-glucans, particularly those from Hericium erinaceus, possess unique structures that enable immunomodulation and anti-inflammatory effects, which can be harnessed for therapeutic uses.
  • The study developed a hydrogel (HEBG/TA) by combining β-glucan with tannic acid, resulting in an injectable material with enhanced antioxidant properties and the ability to manage temperature-responsive drug release.
  • In vivo tests on wound healing showed that this hydrogel significantly improved tissue regeneration, reduced inflammation, and promoted angiogenesis, making it a promising candidate for skin repair treatments.

  • The study examined the physicochemical properties and structural characteristics of polysaccharides from the mushroom Agrocybe cylindracea at four growth stages.
  • Researchers found that although there was a significant drop in polysaccharide yields as the mushroom matured, the overall structural features remained similar across the stages.
  • Notably, the study identified various polysaccharides, including a new type—glucuronofucogalactoglucan—and highlighted changes in their structure during maturation, which could have applications in the food and biomedicine sectors.

Arabinoxylan (AX) is a potential natural food additive that can enhance the textural properties of food. However, the addition of ascorbic acid (AA) can easily lead to a decrease in the viscosity of AX, which poses a challenge in the development of AX-rich foods. Therefore, the purpose of this study is to elucidate the mechanisms behind the reduction in AX viscosity in the presence of AA.

This paper methodically investigates the influence of inclusive income growth on city size, examining it through the dual lenses of "income" and "distribution." The analysis leverages meticulously collected panel data encompassing 276 Chinese cities at the prefecture level and above, spanning the period from 2005 to 2019. Theoretical analysis indicates that the effect of city size expansion on per capita income adheres to a 'U'-shaped trajectory, while its influence on the urban-rural income gap manifests an 'inverted U' pattern.

Purpose: To investigate the expression change of microRNA (miR) - 199a in MC3T3-E1 cells stimulated by mechanical stretch and its mechanism of osteogenic differentiation.

Methods: MC3T3-E1 cells cultured in vitro were loaded with 12% stretch for 0, 3, 6, 12 and 24 hours, alkaline phosphatase (ALP) activity was detected by ALP activity test kit, the expressions of osteocalcin (OCN), osteoblast specific transcription factor osterix (OSX), Runt related transcription factor 2 (Runx2) mRNA and miR-199a were detected by real-time fluorescence quantitative PCR. MC3T3-E1 cells were divided into control group, stretch group, stretch + miR-NC group and stretch + miR-199a group, and the expressions of miR-199a, OCN, OSX, Runx2 mRNA and protein and ALP activity were observed after 12% stretch and transfection of miR-199a.

Improved knowledge on the regulation of reproductive diapause in , an important predator of aphids, is crucial for improving shelf-life and mass production of the ladybeetles. In many insects, the absence of juvenile hormone (JH) is a central regulator of reproductive diapause. JH is principally degraded by JH esterase (JHE) and JH epoxide hydrolase (JHEH).

To identify regulators of triple-negative breast cancer (TNBC), gene expression profiles of malignant parts of TNBC (mTNBC) and normal adjacent (nadj) parts of the same breasts have been compared. We are interested in the roles of estrogen receptor β (ERβ) and the cytochrome P450 family (CYPs) as drivers of TNBC. We examined by RNA sequencing the mTNBC and nadj parts of five women.

Metal-organic frameworks (MOFs) can be fine-tuned to boost sorbent-sorbate interactions in order to improve gas sorption and separation performance, but the design of MOFs with ideal structural features for gas separation applications remains a challenge. Herein it is reported that unsaturated alkali metal sites can be immobilized in MOFs through a tetrazole based motif and that gas affinity can thereby be boosted. In the prototypal MOF of this type-NKU-521 (NKU denotes Nankai University), K cations are effectively embedded in a trinuclear Co -tetrazole coordination motif.

Purpose: Glucocorticoid-induced osteonecrosis of the femoral head (GIONFH) is a common disease following long-term use or large doses of glucocorticoids. The pathogenesis of GIONFH remains controversial, and abnormal bone metabolism caused by glucocorticoids(GCs) may be one of the important factors. Due to its positive effect on bone remodeling, naringin shows potential therapeutic effects in bone metabolism-related diseases.

Metal-organic frameworks (MOFs) with diverse structures, adjustable pore sizes, and high surface areas have exhibited awesome potential in many fields. Here we report a simple carbonization strategy to obtain a series of core-shell structured Co/CoO nanoparticles encapsulated into nitrogen-doped carbon shells from cobalt-based metal-organic framework precursors at different carbonization temperatures. When it is applied as an anodes for lithium ion batteries, the Co/CoO@N-C-700 electrode delivers a maximum initial discharge capacity of 1535 mAh g, the highest reversible capacity (903 mAh g at a current density of 100 mA g after 100 cycles), and the best rate performance (i.
