[Effects of Land Use Types on Water Quality at Different Buffer Scales: Tianjin Section of the Haihe River Basin as an Example].

It is important to explore the relationship between land use types and water quality to improve the surface water environment. Based on monthly water quality monitoring data from 16 nationally controlled surface water quality monitoring stations in Tianjin and land use data in 2021, GIS spatial analysis and mathematical and statistical methods were used to study the influence of land use types on surface water quality in buffer zones at different scales. The results showed that:① the land use types in the study area were mainly construction land, farmland, and water areas, which had significant effects on river water quality.

Highly effective synthesis of novel structured phospholipid emulsifiers using magnetically recyclable FeO@SiO/M (M = Zn or Al) composite.

It is of great importance to develop a most efficient, recyclable, and ecofriendly process to produce novel structured phospholipid emulsifiers. Herein, innovative medium-chain structured phospholipid (MCSPL) emulsifiers were synthesized through transesterification of soybean lecithins with medium-chain fatty acids (MCFAs) promoted by Zn- or Al-incorporated FeO@SiO, denoted by FeO@SiO/M (M = Zn or Al). Resultingly, FeO@SiO/M (M = Zn or Al) exhibited the most superior reactivity with 97.

[Diagnosis and treatment of human monkeypox].

The guideline for the diagnosis and treatment of monkeypox (2022 edition) issued by National Health Commission of the People's Republic of China introduces the key knowledge of the diagnosis and treatment of human monkeypox (HMPX) and does not systematically introduce the sampling methods and requirements of specimens for HMPX etiology testing and the discrepancy in diagnostic criteria between China and overseas. However, the doctors who are not engaged in dermatology lack understanding of the sampling methods and requirements of specimens for laboratory diagnosis of HMPX, and there are few relevant references available. This article collects the information on the diagnosis and treatment of HMPX, so as to provide a reference for learning, understanding, and application of this guideline.

[Accumulation and Transport Characteristics of Cd, Pb, Zn, and As in Different Maize Varieties].

The enrichment and translocation characteristics of Cd, Pb, Zn, and As by various parts of maize plants were investigated using field experiments in 22 maize varieties simultaneously under uncontaminated, low, middle, and serious heavy metal Cd, Pb, Zn, and As complex-contaminated farmland soil conditions. The relationship between the uptake of Cd, Pb, Zn, and As by maize plants and the morphological content of heavy metals in the soil was also discussed through principal component analysis and correlation analysis of the concentrations of eight heavy metals, including Cd, Hg, As, Pb, Cr, Cu, Ni, and Zn. The results showed that:① the distribution pattern of Cd and Zn contents in different parts of the maize plant was as follows:upper stalk>lower stalk>root>seed, the distribution pattern of Pb was As follows:root>lower stalk>upper stalk>seed, and the As distribution pattern was:root>upper stalk>lower stalk>seed.

[Synergistic Repair Effect of Calcite-Based Passivator and Low-Accumulation Maize].

In this study, a field experiment of soil passivation and low accumulation-crops was carried out for typical northern alkaline cadmium and lead compound-polluted farmland soil. Calcite was used as the main passivation material, and a small amount of slaked lime, zeolite powder, and biochar were combined to form a group passivation agent. The effects of passivators on soil physicochemical properties, bioavailability of the heavy metals Cd and Pb, and the yield and plant (stalk and seed) content of heavy metals Cd and Pb in low-accumulation maize were investigated under different grouping conditions of calcite+slaked lime (CL), calcite+zeolite (CZ), calcite+biochar (CB), and calcite+slaked lime+zeolite+biochar (CLZB).

[Cadmium Accumulation Characteristics of Different Heat Varieties Under Cadmium Stress].

In order to provide technical support for the safe utilization of heavy metal-polluted farmland, we screened wheat varieties with a low accumulation of Cd in grain via a pot experiment. For this purpose, we respectively investigated the enrichment and transport characteristics of Cd in various plant parts of 119 wheat varieties under the conditions of 1.5 mg·kg (low content) and 4.

Neuroprotective Effects of Berry on Neurobehavioral Changes and Neuronal Loss in the Hippocampus of Mice Exposed to Acute Ionizing Radiation.

Brain exposure to ionizing radiation during the radiotherapy of brain tumor or metastasis of peripheral cancer cells to the brain has resulted in cognitive dysfunction by reducing neurogenesis in hippocampus. The water extract of berry (Lyc), containing water-soluble polysaccharides and flavonoids, can protect the neuronal injury by reducing oxidative stress and suppressing neuroinflammation. To demonstrate the long-term radioprotective effect of Lyc, we evaluated the neurobehavioral alterations and the numbers of NeuN, calbindin (CB), and parvalbumin (PV) immunopositive hippocampal neurons in BALB/c mice after acute 5.

Epidemiology of non-vaccine serotypes of before and after universal administration of pneumococcal conjugate vaccines.

The universal administration of pneumococcal conjugate vaccines (PCVs) had been demonstrated as an effective way to prevent infection. However, the immunity induced by PCVs protected against the infections caused by vaccine serotypes, which were usually more frequent than non-vaccine serotypes (NVTs). The prevalence and pathogenicity of NVTs after universal vaccination have caused widespread concern.

One cross-sectional investigation revealed that non-vaccine serotypes of Streptococcus pneumoniae could be identified more frequently in elderly Chinese people.

Objective: To analyze the serotype distribution and drug resistance of Streptococcus pneumoniae isolated from hospitalized patients of all ages in Zhongjiang county, Sichuan province, where the young children have just begun to vaccinate the PCV13 in private sector.

Methods: Serotypes were determined for 387 isolates of S. pneumoniae by Quellung reaction.

The effects and mechanisms of a biosynthetic ginsenoside 3β,12β-Di-O-Glc-PPD on non-small cell lung cancer.

Background: A biosynthetic ginsenoside, 3-O-β-D-glucopyranosyl-12-O-β-D-glucopyranosyl-dammar-24-ene-3β, 12β, 20S-triol (CCPPD), showed antitumor activity against many tumor cells in vitro, especially had better anti-lung cancer activity than Rg3 in vitro and in vivo. However, the effects and molecular mechanisms of CCPPD on non-small cell lung cancer (NSCLC) remain unclear. According to previous studies, we hypothesized ginsenoside CCPPD could inhibit the tumor growth of NSCLC by targeting proliferation, migration and angiogenesis.

Combination of 5-deoxy-5-fluorouridine and tamoxifen show cell-type specific antagonistic and cooperative effects on cytotoxicity in human mammary carcinoma cells.

The effect of tamoxifen (Tam) and 5-deoxy-5-fluorouridine (5-DFUR) cotreatment on cytotoxicity was assessed in various cancer-derived cell lines. Each cell line was treated with a range of Tam and 5-DFUR concentrations alone and in combination. The cell lines we examined include MDA-MB-231 (ERalpha-/ERbeta+), T47D (ERalpha+/ERbeta+), and three MCF-7 (ERalpha+/ERbeta+) sublines.

Novel perspective: focusing on the X chromosome in reproductive cancers.

In an XX female, one of the two X chromosomes has been inactivated during early embryonic life to achieve a compensation of X-linked gene products between males and females, leaving only one allele of X-linked genes functional. There are some X-linked genes escaping the X-inactivation, i.e.
