The Concentration Effect of Near-Infrared Quantum Cutting Luminescence of Tm(3+) Ion Sensitized with Bi(3+) Ion in YNbO(4) Phosphor.

Searching for new energy source is one of the most important projects faced by the global, while the most ideal new energy source is solar cell. Near infrared quantum cutting luminescence method can doubly transfer large energy photon which is not sensitive to Si or Ge solar cell to small energy photon which is sensitive to Si or Ge solar cell. It can resolve the spectral mismatch problem and largely enhance solar cell efficiency.

Concurrent tamoxifen-related Müllerian adenofibromas in uterus and ovary.

Tamoxifen is a widely used in anti-oestrogen treatment of breast cancer. Previous reports showed that tamoxifen is associated with proliferative endometrial lesions. We herein reported an unusual case of concurrent hyperplastic lesions in the uterine cavity and right ovary in a 45-year-old woman with tamoxifen therapy.

Prognostic value of pathological response to neoadjuvant chemotherapy in bulky stage Ib2 and IIa cervical squamous cell cancer patients.

Absence of KHDC3L mutations in Chinese patients with recurrent and sporadic hydatidiform moles.

To date, two maternal-effect genes have been shown to play causal roles in recurrent hydatidiform moles (RHMs). NLRP7, a major gene for this condition, codes for a nucleotide-binding oligomerization domain-like receptor and is mutated in 48 to 60% of patients with RHMs. KHDC3L is a recently identified gene that is mutated in 14% of NLRP7-negative patients.

We report 2 unusual cases of gestational trophoblastic disease from chorionic-type intermediate trophoblastic cells after a Cesarean section. A 32-year-old woman presented with a 2-year history of vaginal bleeding, while a 41-year-old woman presented with a pelvic mass. Both patients had cystic lesions with a fistula formation beneath their Cesarean scars in the anterior uterine isthmus.

Structural change from homogenous structure to staging in benzoic acid intercalated LDH: experimental and molecular dynamics simulation insights.

The intercalation the of 4,4'-oxybis(benzoic acid) anion (OBA(2-)) into MgAl-layered double hydroxide (LDH) was carried out in formamide, and the structural change of the nanocomposites from homogenous to staging was investigated through in situ XRD, FT-IR, TG-DSC, SEM and molecular dynamics (MD) simulations. In both formamide and water, the nanocomposites had a homogenous structure with a basal spacing of ∼1.7 nm, showing the configuration of OBA(2-) was vertical to the LDH layers; however, with a decrease in water content after drying, the structure changed to a staging with a basal spacing of 2.
