AI Article Synopsis
- Two types of gratings were created in SMF-28 fiber using focused pulses, with distinct formation mechanisms.
- The first type, type I-IR, forms without damaging the fiber and is likely linked to nonlinear absorption and color center formation.
- The second type, type II-IR, forms during white light generation and is stable at very high temperatures, resulting from damage due to ionization.
Article Abstract
The formation of two grating types in SMF-28 fiber by focusing 125 fs, 0.5-2 mJ pulses through a phase mask onto a fiber sample is studied. The first type, specified as type I-IR, occurs below the damage threshold of the medium. The scaling behavior of the type I-IR gratings with field intensity and annealing properties suggests that their formation is related to nonlinear absorption processes, possibly resulting in color center formation. The second type, denoted as type II-IR, occurs coincidentally with white light generation within the fiber. These type II-IR gratings are stable at temperatures in excess of 1000 masculineC and are most likely a consequence of damage to the medium following ionization.

Article Synopsis
- - The World Health Organization has identified Thailand as a hotspot for leishmaniasis, with increasing cases of the disease caused by two local species leading to various clinical presentations.
- - A new duplex TaqMan quantitative PCR assay was developed to diagnose and differentiate between the two species causing visceral and cutaneous leishmaniasis, utilizing specific primers and probes for accurate detection.
- - The assay demonstrated excellent diagnostic performance, achieving 100% sensitivity and specificity, and proving to be a rapid and cost-effective solution for detecting these parasitic infections in clinical and environmental samples.
DNA methylation mediates the effects of PM and O on ceramide metabolism: A novel mechanistic link between air pollution and insulin resistance.

Insulin resistance (IR), linked to air pollution, is an initial stage of early-onset Type 2 diabetes mellitus (T2DM). While ceramide metabolism plays an important role in IR pathogenesis, the effects of air pollution on this process and its mechanisms remain unclear. We recruited young adults aged 18-30 years to a panel study in Wuhan, China.

Photodynamic therapy (PDT) relying on photosensitizer-induced production of reactive oxygen species (ROS) for killing cancer cells has emerged as a non-invasive anti-cancer strategy. Compared with oxygen-dependent type-II photosensitizers (PSs) for PDT, the development of intrinsic oxygen-independent type-I ones is highly desired but remains a challenge. In this work, two netural Ir(III) complexes that can produce type-I reactive oxygen species, namely MPhBI-Ir-BIQ (Ir-1) and NPhBI-Ir-BIQ (Ir-2), were synthesized.

Background: Patients treated with preoperative chemotherapy with stage I intermediate-risk Wilms tumor (IR-WT) represent the largest group of patients with Wilms tumor (WT), and they have excellent outcomes.
Methods: The authors performed a retrospective analysis of patients with stage I epithelial (ET-WT) or stromal type WT (ST-WT) treated pre- and postoperatively according to the International Society of Paediatric Oncology-WT-2001 protocol in the UK Children's Cancer and Leukaemia Group and Gesellschaft für Pädiatrische Onkologie und Hämatologie groups' participation in the relevant WT trials and studies (2001-2020).
Results: There were 880 patients with stage I IR-WT, including 124 with ET-WT, 156 with ST-WT, and 600 with other IR-WT (oIR-WT).

International Pleuropulmonary Blastoma/DICER1 Registry, Children's Minnesota, Minneapolis, Minnesota, USA.
Purpose: Pleuropulmonary blastoma (PPB) is the most common lung cancer of infancy and early childhood and is associated with germline DICER1 variants. Type I and Ir PPB are cystic lesions treated surgically, with a subset of children with type I receiving chemotherapy. Type II and III are more aggressive lesions, treated with surgery, intensive chemotherapy and potentially radiation.
