Background: Taiwan implemented global hospital budgeting with a floating-point value, which created a prisoner's dilemma. As a result, hospitals increased service volume, which caused the floating-point value to drop to less than one New Taiwan Dollar (NTD). The recent increase in the number of hospital beds and the call to enhance the floating-point value to one NTD raise concerns about the potential for increased financial burden without adding value to patient care if hospitals expand their bed capacity for volume-based competition.

: Transitional attachment objects, such as blankets, play a critical role in childhood by helping children manage separation anxiety and regulate emotions. Although attachment to these objects often decreases as children grow older, it may persist into adulthood and influence emotion regulation and stress responses. Their influence on emotion regulation in adulthood remains uncertain.

One undescribed xanthone, hypersine H (1), together with three known analogs, 3,7-dihydroxy-1-methoxyxanthone (2), 1,7-dihydroxy-5,6-dimethoxyxanthone (3), and 1,5-dihydroxy-6,7-dimethoxyxanthone (4), were isolated from the whole plant of Hypericum elodeoides Choisy. Their structures, including absolute configurations, were unambiguously elucidated by HR-ESI-MS, extensive NMR spectroscopy, and quantum chemical calculation of electronic circular dichroism (ECD) method. Moreover, the anti-neuroinflammation activities of isolated compounds were evaluated.

Overexpression of OsSTP1 enhances the non-structural carbohydrate remobilization in the source, starch accumulation in grains, and the transportation of carbohydrates from source to sink during the filling stage. The sugar transporter protein (STP) is the best-characterized subfamily of the monosaccharide transporter (MST) family and plays critical roles in regulating plant stress tolerance, growth, and development. However, the role of STPs in regulating rice yield is poorly understood.

Purpose: Group B streptococci (GBS) are Gram-positive bacteria that are a leading cause of neonatal infections. Most invasive isolates are β-hemolytic, and hemolytic activity is critical for GBS virulence. Although nonhemolytic GBS strains are occasionally isolated, they are often thought to be attenuated in virulence.

Background: Non-operative management (NOM) with antibiotics alone for pediatric uncomplicated appendicitis is accepted to be safe and effective. However, the relative cost-effectiveness of this approach compared to appendectomy remains unknown. We aimed to evaluate the cost-effectiveness of non-operative versus operative management for pediatric uncomplicated acute appendicitis.

Article Synopsis
  • The subtropical forests of East Asia host diverse and ancient plant species, but their evolutionary history and ability to adapt to climate change are not well understood.
  • Using whole-genome resequencing of the endangered tree species (Akaniaceae), researchers explored its lineage differences and demographic history, employing genomic approaches to assess mutation loads and climate responses.
  • Findings indicated significant genomic divergence between eastern and western populations due to historical climatic shifts, with edge populations showing higher mutation loads, suggesting they are more vulnerable to climate change and highlighting the need for targeted conservation efforts.

This study explores materiality and material cultures of human placenta in Ming China (1368-1644), for it perfectly displays Chinese ambiguous attitudes towards the human body parts between living and non-living. For a long time, the Chinese had widely applied human body parts in medical treatments and ritual healings. Numerous evidences in relation to their collection, production, efficacy and application are widely recorded in medical works, in particular those found in materia medica.

The development of tumors relies on lactate metabolic reprogramming to facilitate their unchecked growth and evade immune surveillance. This poses a significant challenge to the efficacy of antitumor immunity. To address this, a tumor-selective nano-dispatcher, PIMDQ/Syro-RNP, to enforce the immunotherapeutic effect through regulation of lactate metabolism and activation of toll-like receptors is developed.

Intrinsically disordered proteins (IDPs) lack stable tertiary structures under physiological conditions, yet play key roles in biological processes and associated with human complex diseases. Their conformational characteristics and high content of charged residues make the use of polarizable force fields an advantageous for simulating IDPs. The Drude2019IDP polarizable force field, previously introduced, has demonstrated comprehensive enhancements and improvements in dipeptides, short peptides, and IDPs, achieving a balanced sampling between IDPs and structured proteins.

Objective: Brown adipose tissue (BAT) plays an important role in mammalian thermogenesis through the expression of uncoupling protein 1 (UCP1). Our previous study identified cytoplasmic polyadenylation element binding protein 2 (CPEB2) as a key regulator that activates the translation of Ucp1 with a long 3'-untranslated region (Ucp1L) in response to adrenergic signaling. Mice lacking CPEB2 or Ucp1L exhibited reduced UCP1 expression and impaired thermogenesis; however, only CPEB2-null mice displayed obesogenic phenotypes.
