Summary: We investigated the effect of different forest covers on carbon and nitrogen dynamics of two types of litter during decomposition in soil. The results showed that the carbon to nitrogen ratio of green tea remained unchanged, while the ratio of rooibos tea nearly halved after two years. Both litters progressively lost carbon, with rooibos tea losing about fifty percent of the initial content. In terms of nitrogen, green tea behaved similarly to carbon, while rooibos tea initially lost nitrogen but recovered by the end of the first year. Both litters showed preferential loss of carbohydrates and enrichment in lipids under beech.

Summary: This study compares the effects of green tea (GT) and GT loaded in lyotropic liquid crystals (LLCs) on animals subjected to high-intensity interval training (HIIT). The results show that GT loaded in LLCs, combined with HIIT, leads to greater muscle hypertrophy, improved physical conditioning, and reduced body weight gain rate compared to HIIT alone. Additionally, the LLCs may enhance the bioavailability of GT.

Summary: This study used bioinformatics approaches to screen and identify key genes of idiopathic calcium oxalate nephrolithiasis, and explored its potential molecular mechanism. By analyzing gene expression and protein-protein interactions, a network was constructed. Functional annotation and pathway enrichment analysis were performed for differentially expressed genes. Retrospective analysis of clinical data identified several factors associated with the development of urogenous sepsis. These parameters offer a viable treatment paradigm for the perioperative management of idiopathic calcium oxalate kidney stones.

Summary: Ureterocele prolapse can lead to voiding difficulty and the condition may go unnoticed if the abnormal voiding behavior is not observed. A 6-year-old boy with this condition was treated with transvesicoscopic ureteral reimplantation and ureterocele removal, resulting in improved voiding. Diagnosing congenital bladder obstructions can be challenging if the patient adapts to the voiding difficulty.

Summary: This study retrospectively analyzed the surgical management of prepubertal testicular tumors based on cases observed over approximately 30 years. The results showed that patients who underwent testis-sparing surgery (TSS) had significantly smaller tumor sizes compared to those who underwent radical orchiectomy (RO). Patients treated after 2005 were more likely to undergo TSS, but there were no significant differences in tumor size or the rate of preoperative ultrasound.

Summary: We conducted a study to quantitatively analyze calcium oxalate (CaOx) kidney stones at the micrometer level, with a focus on the identification of calcium oxalate monohydrate (COM) and dihydrate (COD). We used Fourier transform infrared (FTIR) spectroscopy, powder X-ray diffraction (PXRD), and microfocus X-ray computed tomography measurements (microfocus X-ray CT) to compare their results. By analyzing the FTIR spectrum at the 780 cm(-1) peak, we successfully achieved a reliable analysis of the COM/COD ratio. This quantitative analysis method provides valuable information on the composition and formation processes of kidney stones.

Summary: In this study, hyperthermia was investigated as an alternative treatment for castration-resistant prostate cancer (CRPC). Silencing the HIKESHI gene expression enhanced the effect of hyperthermia and a novel magnetic nanoparticle, CNH-APTES-IONP, showed significant suppression of tumor growth in a mouse model. These findings suggest that HIKESHI silencing and CNH-APTES-IONP have potential as therapeutic options for hyperthermia treatment.

Summary: The introduction of second-generation androgen receptor axis-targeted agents (ARATs) has greatly improved the treatment of metastatic hormone-sensitive prostate cancer (mHSPC). A retrospective study involving 581 newly diagnosed mHSPC patients was conducted to compare the efficacy of different ARATs. It was found that there were no significant differences in patient characteristics or biochemical recurrence-free survival (BRFS) among patients receiving different ARATs as first-line treatment. Neutrophil-to-lymphocyte ratio (NLR) and PSA level were identified as independent predictors of biochemical recurrence (BCR) following first-line treatment of mHSPC patients.
