Multifunctional nanocomposites utilizing ruthenium (II) complex/manganese (IV) dioxide nanoparticle for synergistic reinforcing radioimmunotherapy.

Radiotherapy (RT) stands as a frontline treatment modality in clinical breast oncology, yet challenges like ROS reduction, high toxicity, non-selectivity, and hypoxia hinder efficacy. Additionally, RT administered at different doses can induce varying degrees of radioimmunotherapy. High doses of radiation (>10 Gy) may result in immune suppression, while moderate doses (4-10 Gy), although capable of mitigating the immune suppression caused by high-dose radiation, are often insufficient in effectively killing tumor cells.

[Historical evolution of Salviae Miltiorrhizae Radix et Rhizoma processing methods].

China has a long history of Salviae Miltiorrhizae Radix et Rhizoma processing with multiple methods available. The pre-sent study collated and summarized the Salviae Miltiorrhizae Radix et Rhizoma processing methods recorded in 23 related herbal medicine books, all editions of Chinese Pharmacopoeia, the 1988 edition of National Regulations for Processing of Chinese Medicine, and 20 current local processing specifications and standards. The results demonstrated various processing methods of Salviae Miltiorrhizae Radix et Rhizoma, such as removing residual part of stem, plantlet, or soil, smashing, filing, cutting, decocting, washing with wine, soaking in wine, and stir-frying with wine or blood from pig heart, while raw and wine-processed products are mainly used in modern times.

[Expression of inhibin B betaB subunits in the testicular tissues of azoospermia patients with different pathological alterations].

Objective: To investigate the expression of inhibin B betaB subunits in human testicular tissues.

Methods: Eighty-three cases of the azoospermia underwent testicular biopsy. In accordance with the pathological alterations of spermatogenesis, the samples were divided into four groups: Sertoli-cell-only syndrome (n = 21); hypospermatogenesis (n = 20), maturation arrest (n = 24) and almost normal spermatogenesis (n = 18).

[Relationship between pathological alterations of spermatogenic impairment and serum inhibin B concentration in patients with azoospermia].

Objective: To investigate the relationship between pathological alterations of spermatogenic impairment in seminiferous tubules and serum inhibin B concentration in patients with azoospermia and to verify the significance of INH B in evaluating spermatogenesis.

Methods: Eighty-three cases of azoospermia underwent testicular biopsy for the purpose of diagnosis. In accordance with the pathological alterations of spermatogenesis in seminiferous tubules, the samples were divided into four groups: Sertoli cell-only syndrome (n = 21); hypospermatogenesis (n = 20); maturation arrest (n = 24) and almost normal spermatogenesis (n = 18).

[Contrasting experiment of two types of MSW aerobic bioreactor landfill].

Bioreactor landfill is an emerging landfilling method, which represents the newest developing aspect of Municipal Solid Wastes (MSW) treatment. On basis of analyzing the merits and defects of present bioreactor landfilling methods, the paper improves these methods and combines organically aeration and leachate recirculation into a new reactor (called reactor A), which is contrasted with bare aerobic landfill (called reactor B). During the course of experiment, NH3, CH4, CO2, pH, temperature and electric conductivity in the two bioreactors were controlled and detected, meanwhile, COD, Fe3+, NH4(+) in the leachate were detected and analyzed.
