Exploring the nematicidal mechanisms and control efficiencies of oxalic acid producing WF01 against root-knot nematodes.

Background And Aims: Root-knot nematodes (RKN; spp.) are among the highly prevalent and significantly detrimental pathogens that cause severe economic and yield losses in crops. Currently, control of RKN primarily relies on the application of chemical nematicides but it has environmental and public health concerns, which open new doors for alternative methods in the form of biological control.

A GP130-Targeting Small Molecule, LMT-28, Reduces LPS-Induced Bone Resorption around Implants in Diabetic Models by Inhibiting IL-6/GP130/JAK2/STAT3 Signaling.

In this study, we examined the effect of the GP130-targeting molecule, LMT-28, on lipopolysaccharide- (LPS-) induced bone resorption around implants in diabetic models using in vitro and rat animal experiments. First, LMT-28 was added to osteoblasts stimulated by LPS and advanced glycation end products (AGEs), and nuclear factor-B receptor-activating factor ligand (RANKL) and associated pathways were evaluated. Then, LMT-28 was administered by gavage at 0.

Overexpression of CD155 is associated with PD-1 and PD-L1 expression on immune cells, rather than tumor cells in the breast cancer microenvironment.

Background: CD155 is an immune checkpoint protein in cancers and interacts with ligands to regulate the immune microenvironment. The expression of CD155 is correlated with the prognosis and pathological features of breast cancer.

Aim: To investigate the expression status of CD155 and the association with exhausted CD4 helper and CD8 cytotoxic tumor infiltrating lymphocytes (TILs) and PD-L1 in the breast cancer microenvironment.

Overexpression of an Immune Checkpoint (CD155) in Breast Cancer Associated with Prognostic Significance and Exhausted Tumor-Infiltrating Lymphocytes: A Cohort Study.

Purpose: The immune checkpoint inhibitor is approved for breast cancer treatment, but the low expression of PD-L1 limits the immunotherapy. CD155 is another immune checkpoint protein in cancers and interacts with ligands to regulate immune microenvironment. This study is aimed at investigating the expression of CD155 and the association with prognosis and pathological features of breast cancer.

Increased risk of esophageal squamous cell carcinoma associated with frequent and long-term consumption of salted meat and salted fat.

Objective: This study aimed to investigate the association between the consumption of salted meat and salted fat and esophageal cancer risk among individuals with normal esophageal mucosa or esophagitis.

Methods: This case-control study enrolled 216 individuals from Yanting County. Information on the consumption of salted meat and salted fat was collected using a food-frequency questionnaire validated among Yanting people.

Expression of PD-1 on CD4 Tumor-Infiltrating Lymphocytes in Tumor Microenvironment Associated with Pathological Characteristics of Breast Cancer.

Objective: This study aimed to investigate the correlation of CD4/PD-1 or CD4/PD-1 tumor-infiltrating lymphocytes with pathological characteristics in breast cancer patients.

Methods: A cross-sectional study consecutively recruited 133 patients with invasive ductal breast cancer. The expression of CD4, programmed cell death protein 1 (PD-1), CK7, CK20, E-cadherin, or Ki-67 was detected by immunohistochemistry.

Cytokine-induced killer cell infusion combined with conventional treatments produced better prognosis for hepatocellular carcinoma patients with barcelona clinic liver cancer B or earlier stage: A systematic review and meta-analysis.

Background Aims: To investigate the clinical benefits of cytokine-induced killer (CIK) cell infusions on hepatocellular carcinoma (HCC) patients, combined with other conventional treatments.

Methods: This was a systematic review and meta-analysis conducted among phase II and III randomized control trials worldwide. Review manager 5.

[Form of the particulate matter ambient air standards in China].

Based on the principles from the World Health Organization (WHO) and the United States, an analysis was conducted to study the form of 24-hour standard of particulate matter in China by methods of statistical regression, proportional rollback and controlling contrast maps, using the monitoring data of inhalable particulate matter (PM10) from 120 cities in China during year 2005 to 2012. It was found that for cities in China, when the annual arithmetic mean of PM10 was equal to the national standard, the non-exceedance rates of daily average PM10 in most cities were higher than 95.0% , and the average rate for all cities was 97.

UV-B-induced stomatal closure occurs via ethylene-dependent NO generation in Vicia faba.

The role of ethylene and the relationship between ethylene and nitric oxide (NO) in ultraviolet B (UV-B)-induced stomatal closure were investigated in Vicia faba L. (broad bean) plants by epidermal strip bioassay, laser-scanning confocal microscopy and assay of ethylene production. In response to UV-B radiation, the rise of NO level in guard cells was after ethylene evolution peak, but preceded stomatal closure.

A practical and azide-free synthetic approach to oseltamivir from diethyl D-tartrate.

A short and practical synthesis of oseltamivir was accomplished in 11 steps from inexpensive and abundant diethyl D-tartrate starting material. This azide-free route featured an asymmetric aza-Henry reaction and a domino nitro-Michael/Horner-Wadsworth-Emmons (HWE) reaction as the key steps to construct the relevant cyclohexene ring of the product, which provided an economical and practical alternative for the synthesis of oseltamivir.

The involvement of nitric oxide in ultraviolet-B-inhibited pollen germination and tube growth of Paulownia tomentosa in vitro.

The role of nitric oxide (NO) in the ultraviolet-B radiation (UV-B)-induced reduction of in vitro pollen germination and tube growth of Paulownia tomentosa Steud. was studied. Results showed that exposure of the pollen to 0.
