Flexible Quasi-2D Perovskite/IGZO Phototransistors for Ultrasensitive and Broadband Photodetection.

Organic-inorganic hybrid perovskites (PVKs) have recently emerged as attractive materials for photodetectors. However, the poor stability and low electrical conductivity still restrict their practical utilization. Owing to the quantum-well feature of two-dimensional (2D) Ruddlesden-Popper PVKs (2D PVKs), a promising quasi-2D PVK/indium gallium zinc oxide (IGZO) heterostructure phototransistor can be designed.

[Advances in relationship between gastric disease and polymorphisms in both Helicobacter pylori virulence factors and host genetics].

Helicobacter pylori infection may cause many gastric disease, such as peptic ulcers, chronic atrophic gastritis, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. The different clinical outcomes of Helicobacter pylori infection are related to H. pylori virulence factors and host gene polymorphism.

Expression of transcriptional repressor Slug gene in mouse endometrium and its effect during embryo implantation.

Slug, a member of the Snail family of zinc-finger transcription factors, is involved in regulating embryonic development and tumorigenesis. The aim of this study was to investigate the expression of Slug in mouse endometrium during early pregnancy and its possible role during embryo implantation. Fluorescence quantitative polymerase chain reaction and immunohistochemistry were applied to detect Slug mRNA and Slug protein expression in endometrium of nonpregnant and early pregnant mice, respectively.

The role of T-lymphoma invasion and metastasis inducing protein 1 in early pregnancy in mice.

T-lymphoma invasion and metastasis inducing protein 1 (Tiam1) is involved in tumorigenesis processes, including cell migration, adhesion and invasion, proteolysis, cytoskeleton reorganization, cell morphological transformation and intracellular signaling. These processes are also critical for embryo implantation, although the role of Tiam1 during embryo implantation remains poorly understood. The aim of this study was to investigate the spatio-temporal expression of Tiam1 in endometria of mice comparing early pregnancy and non-pregnancy.

Expression of p16INK4a in mouse endometrium and its effect during blastocyst implantation.

The expression of tumor suppressor gene p16INK4a in mouse endometrium during early pregnancy and its possible role in blastocyst implantation were investigated in the present study. Real-time fluorescent quantitative PCR (FQ-PCR) and immunohistochemistry were applied to detect p16INK4a mRNA and protein expressions in endometrium of un-pregnant and pregnant mice on day 2, 3, 4, 5, 7, respectively. In addition, p16INK4a antibody was injected into the horns of uteri in pregnant mice on day 3 and its effect during blastocyst implantation was detected in vivo.

Expression of phosphatase and tensin homolog deleted on chromosome ten in mouse endometrium and its effect during blastocyst implantation.

The present study was aimed to investigate the expression of tumor suppressor gene PTEN (phosphatase and tensin homolog deleted on chromosome ten) in mouse endometrium during early pregnancy and its possible role during blastocyst implantation. Real-time fluorescent quantitative PCR (FQ-PCR) and immunohistochemical techniques were applied to detect PTEN mRNA and protein expressions in endometrium in un-pregnant and pregnant mice on days 1, 3, 4, 5, 7 of pregnancy, respectively. In addition, PTEN antisense oligonucleotide was injected into the horns of uterus in pregnant mice on day 3 of pregnancy and its effects on blastocyst implantation was detected in vivo.

Cytogenetic studies of a series of 43 consecutive secondary myelodysplastic syndromes/acute myeloid leukemias: conventional cytogenetics, FISH, and multiplex FISH.

We report a series of 43 consecutive therapy-related myelodysplastic syndromes (t-MDS) or acute myeloid leukemias (t-AML) observed for 6 years. This series consisted of 26 women and 17 men, ages ranging from 9 to 85 years. These cases were classified into three groups according to the primary diagnosis.
