Graphitic carbon nitride (g-C3N4) has gained significant attention as a promising nonmetallic semiconductor photocatalyst due to its photochemical stability, favorable electronic properties, and efficient light absorption. Nevertheless, its practical applications are hindered by limitations such as low specific surface area, rapid recombination of photogenerated charge carriers, poor electrical conductivity, and restricted photo-response ranges. This review explores recent advancements in the synthesis, modification and application of g-C3N4 and its nanocomposites with a focus on addressing these challenges.

Significant progress has been made in cancer therapy with protein-based nanocarriers targeted directly to surface receptors for drug delivery. The nanocarriers are a potentially effective solution for the potential drawbacks of traditional chemotherapy, such as lack of specificity, side effects, and development resistance. Peptides as nanocarriers have been designed based on their biocompatible, biodegradable, and versatile functions to deliver therapeutic agents into cancer cells, reduce systemic toxicity, and maximize therapy efficacy through utilizing targeted ligands such as antibodies, amino acids, vitamins, and other small molecules onto protein-based nanocarriers and thus ensuring that drugs selectively accumulate in the cancer cells instead of healthy organs/drug release at a target site without effects on normal cells, which inherently caused less systemic toxicity/off-target effect.

Objectives: Patient experience surveys are essential to measuring patient-centered care, a key component of health care quality. Low response rates in underserved groups may limit their representation in overall measure performance and hamper efforts to assess health equity. Telephone follow-up improves response rates in many health care settings, yet little recent work has examined this for surveys of Medicare enrollees, including those with Medicare Advantage.

Objectives: To assess trends in the medical loss ratio (MLR) and understand how health insurance premiums in the large group market are driven by medical claims spending and insurer margins.
Study Design: Study of approximately 500 insurers covering more than 40 million lives annually in the large group market that submitted an MLR submission form (2014-2022).
Methods: We assessed trends in the MLR, premiums, medical claims spending, administrative costs, quality improvement spending, and margins among all insurers in the large group market.

Objectives: Medicaid is the largest payer of mental health (MH) services in the US, and more than 80% of its enrollees are covered by Medicaid managed care (MMC). States are required to establish quantitative network adequacy standards (NAS) to regulate MMC plans' MH care access. We examined the association between quantitative NAS and MH care access among Medicaid-enrolled adults and among those with MH conditions.
