Nature's disguise: Empirical demonstration of dead-leaf masquerade in butterflies.

Animals deploy diverse color-based defenses against predators, including crypsis, mimicry, aposematism, and masquerade. While crypsis, mimicry, aposematism have been extensively studied, the strategy of masquerade-where organisms imitate inedible or inanimate objects such as leaves, twigs, stones, and bird droppings-remains comparatively underexplored, particularly in adult butterflies. The Indian oakleaf butterfly ( ) exemplifies this phenomenon, with its wings resembling dead leaves, providing a classic example of natural selection.

Combination of and Low Fertigation Input Promoted the Growth and Productivity of Chinese Cabbage and Enriched Beneficial Rhizosphere Bacteria .

Long-term overfertilization increases soil salinity and disease occurrence and reduces crop yield. Integrated application of microbial agents with low fertigation input might be a sustainable and cost-effective strategy. Herein, the promoting effects of B006 on the growth of Chinese cabbage under different fertigation conditions in field trials were studied and the underlying mechanisms were revealed.

Serial spot urine specimens were collected during her hospitalization and were measured by As-Ce catalytic spectrophotometry on a Beckman Coulter AU5800.

High expression of squamous cell carcinoma antigen in poorly differentiated adenocarcinoma of the stomach: A case report.

Background: Squamous cell carcinoma antigen (SCCA) is regarded as a specific indicator of epithelial malignancies and is widely used in the diagnosis of squamous cell carcinoma (SCC). However, the expression of SCCA in gastric adenocarcinoma has not been studied in detail.

Case Summary: A 52-year-old man was admitted to our hospital for a 2.

[Preparation of evodiamine-glycyrrhizic acid micelles with glycyrrhizic acid as carrier and their anti-hepatic fibrosis activity].

This study aimed to prepare evodiamine-glycyrrhizic acid(EVO-GL) micelles to enhance the anti-hepatic fibrosis activity of evodiamine. Firstly, EVO-GL micelles were prepared with use of thin film dispersion method. With particle size, encapsulation efficiency, loading capacity of micelles and the solubility of evodiamine as the indexes, the effect of different factors on micelles was observed to screen the optimal preparation methods and process.

Development and validation of a prediction model for microvascular invasion in hepatocellular carcinoma.

Background: Microvascular invasion (MVI) is an important prognostic factor affecting early recurrence and overall survival in hepatocellular carcinoma (HCC) patients after hepatectomy and liver transplantation, but it can be determined only in surgical specimens. Accurate preoperative prediction of MVI is conducive to clinical decisions.

Aim: To develop and validate a preoperative prediction model for MVI in patients with HCC.

Value of dynamic plasma cell-free DNA monitoring in septic shock syndrome: A case report.

Background: Mortality due to septic shock is relatively high. The dynamic monitoring of plasma cell-free DNA (cfDNA) can guide the treatment of septic shock.

Case Summary: Herein, we present a typical case of septic shock syndrome caused by the bacilli and .

Liquid biopsy for non-invasive assessment of liver injury in hepatitis B patients.

Background: Hepatitis B is a major public health problem in China. Accurate liver injury assessment is essential for clinical evidence-based treatment. Liver biopsy is considered the gold standard method to stage liver disease, but it is not widely used in resource-limited settings.

Tegafur deteriorates established cardiovascular atherosclerosis in colon cancer: A case report and review of the literature.

Background: Cardiac toxic effect of tegafur (S-1) is extremely rare, and there has been no report on this issue so far.

Case Summary: We herein report a typical case of single S-1 administration after radical operation for colon cancer. The patient had no background or medical history of acute coronary syndrome (ACS), and only aortic and coronary atherosclerosis was revealed by computed tomography (CT) before surgery.

Possible connection between elevated serum α-fetoprotein and placental necrosis during pregnancy: A case report and review of literature.

Placenta previa is the main cause of bleeding throughout pregnancy, and it is associated with serious complications, such as infection, that lead to a poor prognosis. Gynecological sonography is recommended as the first-line examination technique for the surveillance and determination of vaginal bleeding and for early intervention. We report the case of a patient with gradually expanded hypoechoic lesion and extremely high serum α-fetoprotein level during her third trimester, and discuss their potential relationship in evaluating the progression of placental necrosis.

In vivo distribution and pharmacokinetics of multiple active components from Danshen and Sanqi and their combination via inner ear administration.

Ethnopharmacological Relevance: Salvia miltiorrhiza Bunge (Labiatae sp. plant, Chinese name Danshen) and Panax notoginseng (Burk.) F.

Adipose-derived stem cells induced dendritic cells undergo tolerance and inhibit Th1 polarization.

Adipose tissue-derived stem cells (ADSC) have been shown to possess stem cell properties such as transdifferentiation, self-renewal and therapeutic potential. However, the property of ADSC to accommodate immune system is still unknown. In this study, ADSC were cocultured with allogenetic dendritic cells (DC), and then treated DC were mixed with allogenetic CD4+ T cells.

Allogeneic adipose-derived stem cells with low immunogenicity constructing tissue-engineered bone for repairing bone defects in pigs.

The ideal cells for tissue engineering should have the following characteristics: easy obtainment, safety, immune privilege, the capability of self-renewal, and multipotency. Adipose-derived stem cells (ADSCs) are a promising candidate. However, the immunogenicity of allogeneic mesenchymal stem cells limits their long-term benefits.

Porous and single-skinned polyethersulfone membranes support the growth of HepG2 cells: a potential biomaterial for bioartificial liver systems.

In this study, we evaluated a porous and single-layer skin polyethersulfone (PES) membrane as a material for use in hybrid bioartificial liver support systems. The PES membrane has been characterized as a single-layer skin structure, with a rough porous surface. Specifically, we studied the ability of the human hepatoblastoma cell lines (HepG2) to adhere, grow, and spread on the PES membrane.

Heparin-chitosan-coated acellular bone matrix enhances perfusion of blood and vascularization in bone tissue engineering scaffolds.

Currently, the main hurdle in the tissue engineering field is how to provide sufficient blood supply to grafted tissue substitutes in the early post-transplanted period. For three-dimensional, cell-dense, thick tissues to survive after transplantation, treatments are required for hypoxia, nutrient insufficiency, and the accumulation of waste products. In this study, a biomacromolecular layer-by-layer coating process of chitosan/heparin onto a decellularized extracellular bone matrix was designed to accelerate the blood perfusion and re-endothelialization process.

Response of porcine hepatocytes in primary culture to plasma from severe viral hepatitis patients.

Aim: To observe the effects of plasma from patients with severe viral hepatitis (SVHP) on the growth and metabolism of porcine hepatocytes and the clinical efficiency of bioartificial liver device.

Methods: Hepatocytes were isolated from male porcines by collagenase perfusion. The synthesis of DNA and total protein, leakages of AST and LDH, changes in glutathione (GSH), catalase and morphology of porcine hepatocytes exposed to SVHP were investigated to indicate the effect of plasma from patients with severe hepatitis on the growth, injury, detoxification, and morphology of porcine hepatocytes.
