Three organic or hybrid photovoltaic technologies are compared with respect to performance and stability under the harsh regime of concentrated light. Although all three technologies show surprisingly high (and linear) photocurrents, and better than expected stability, no golden apples are awarded.

Background: The Compress is designed to achieve bone formation and stability by applying pressure at the bone-implant interface, minimizing the likelihood of aseptic loosening, which is a complication of stem implants. Herein, we report two cases of implant failure using the Compress.
Case Presentation: Case 1 describes a 36 year-old Japanese man who underwent extraarticular tumor resection, Compress arthroplasty, and reconstruction with a gastrocnemius flap after preoperative chemotherapy for a secondary malignant giant cell tumor in the right distal femur.

Background: Motion complexity is necessary for adapting to external changes, but little is known about trunk motion complexity during seated perturbation in individuals with spinal cord injury (SCI). We aimed to investigate changes following SCI in trunk segmental motion complexity across different perturbation directions and how they affect postural control ability in individuals with SCI.
Methods: A total of 17 individuals with SCI and 18 healthy controls participated in challenging sagittal-seated perturbations with hand protection.

Background: The heterogeneity of cognitive impairments in schizophrenia has been widely observed. However, reliable cognitive boundaries to differentiate the subgroups remain elusive. The key challenge for cognitive subtyping is applying an integrated and standardized cognitive assessment and understanding the subgroup-specific neurobiological mechanisms.

Background/aims: Gastric cancer (GC) is a significant global health issue with high incidence rates and poor prognoses, ranking among the top prevalent cancers worldwide. Due to undesirable side effects and drug resistance, there is a pressing need for the development of novel therapeutic strategies. Understanding the interconnectedness of the JAK2/STAT3/mTOR/PI3K pathway in tumorigenesis and the role of Astaxanthin (ASX), a red ketocarotenoid member of xanthophylls and potent antioxidant and anti-tumor activity, can be effective for cancer treatments.

Background: Placenta accreta spectrum (PAS) disorder is a fatal condition responsible for obstetric haemorrhage, which contributes to increased feto-maternal morbidity and mortality. The main contributing factor is a scarred uterus, often from a previous cesarean delivery, myomectomy, or uterine instrumentation. The occurrence of PAS in an unscarred uterus is extremely rare, with only anecdotal cases reported so far in the literature.
