Genomic DNA is assembled into chromatin by histones, and extruded into loops by cohesin. These mechanisms control important genomic functions, but whether histones and cohesin cooperate in genome regulation is poorly understood. Here we identify Phf2, a member of the Jumonji-C family of histone demethylases, as a cohesin-interacting protein.

In recent years, the advent of indirect 3D printing technology has overcome the stringent material demands, confined resolution, and structural control challenges inherent to direct 3D printing. By utilizing sacrificial templates, the natural structures and physiological functions of bone tissues can be precisely duplicated.

Cross-β structures are crucial in driving protein folding and aggregation. However, due to their strong aggregating tendency, the precise control of the self-assembly of β-sheet-forming peptides remains a challenge. We propose a molecular geometry strategy to study and control the self-assembly of cross-β structures.

Salicylic acid (SA) is a major stress signaling molecule that alleviates Cd toxicity in various plants. Our study aimed to investigate the effects of different SA concentrations on spinach growth, cadmium accumulation, and stress resistance physiology under cadmium stress (50 µmol/L).

Methods: In total, 184 volunteers were recruited and grouped into control (n = 121) and temporomandibular disorder (TMD) groups (n = 63) according to the dual-axis DC/TMD checklist. 3D trajectories were generated by integrating mandibular motion and cone beam computed tomography (CBCT) records.

Low temperature restricts the growth, development, and yield of peppers, significantly limiting the development of the pepper industry. NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) are implicated in plant responses to cold stress, but their specific mechanisms in peppers are unclear. In this study, we isolated a cold-induced NAC transcription factor, CaNAC76, from pepper (Capsicum annuum L.

Cultured naïve pluripotent embryonic stem cells (ESC) differentiate into extra-embryonic endoderm/extraembryonic endoderm (XEN) or formative pluripotent ESC, during the period emulating maximal miscarriage of peri-implantation development. In previous reports using small marker sets, hyperosmotic sorbitol, or retinoic acid (RA) decreased naïve pluripotency and increased XEN by FACS quantitation.

Sm-ring assembly is cytoplasmic and dependent upon the Sm-site sequence and structural motif, ATP, and (SMN) protein complex. While RNAs other than U snRNAs were previously shown to associate with Sm proteins, whether this association follows Sm-ring assembly requirements is unknown.

Capsicum (chili pepper), a tropical and subtropical vegetable crop, is extremely sensitive to cold. Although HS is an important signaling regulator in the responses of plant growth and development to abiotic stress, few studies have examined its effects on cold-sensitive capsicum varieties.

We present the crystal structure of AGO3 in complex with a cityRNA, 14-nt miR-20a, and its complementary target, revealing a different trajectory for the guide-target duplex from that of its ∼22-nt microRNA-associated AGO counterpart. cityRNA-loaded Argonaute2 (AGO2) and AGO3 enhance their endonuclease activity when the immediate 5' upstream region of the tyRNA target site (UTy) includes sequences with low affinity for AGO.

Here, we present a protocol for processing electronic medical records from 1,336 peritoneal dialysis patients with more than 10,000 follow-up records. We describe steps for environment setup and transforming records into analyzable formats.

We investigated the association between the clinical characteristics of PDAP and susceptibility to vancomycin and investigated the possibility of using vancomycin monotherapy alone as an initial treatment regimen for some PDAP patients to avoid unnecessary antibiotic exposure and secondary infection.
Methods: Patients with culture-positive PDAP were retrospectively analyzed and divided into two groups: peritonitis with only cloudy effluent (PDAP-cloudy) or with cloudy effluent, abdominal pain and/or fever (PDAP-multi).
Reproductive traits are vital economic parameters in goat production, and boosting the reproductive capacity of breeding rams is crucial for enhancing the profitability of goat farming. Currently, research on the reproductive performance of Qianbei Ma goats mainly centers on investigating mechanisms associated with prolificacy and estrous ovulation in ewes, with limited emphasis on ram reproductive aspects. This study used scanning electron microscopy and enzyme-linked immunosorbent assay (ELISA) to profile the morphology of testis and the dynamic changes of Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), and Testosterone (T) in serum at different developmental stages of Qianbei Ma goats.

The expression pattern of in the testis and its regulatory effect on testicular cells was explored in goats to enhance our understanding of spermatogenesis and improve reproduction in breeding rams. In this study, we demonstrated the localization of in testicular cells using immunohistochemistry and subcellular localization analyses. Subsequently, we analyzed the expression pattern in four age-based groups (0, 6, 12, and 18 months old) using real-time quantitative polymerase chain reaction (qRT-PCR) and protein blotting.

Radical nephroureterectomy (RNU) with bladder sleeve resection is currently the gold standard for the treatment of high-risk ureteral cancer. However, in certain special cases, such as bilateral upper tract urothelial carcinoma(UTUC), isolated and chronic kidney disease, and low-risk UTUC, kidney sparing surgery(KSS) may represent a viable alternative, though it remains highly challenging. The current KSS options for ureteral cancer include endoscopic treatment, segmental ureterectomy, total ureterectomy combined with kidney autotransplantation and nephrostomy.
