Purpose: Hematopoietic stem cell transplantation (HSCT) has been an important method of treatment in the advance of pediatric acute lymphoblastic leukemia (ALL). The indications for HSCT are evolving and require updated establishment. In this study, we aimed to investigate the efficacy of HSCT on the treatment outcome of pediatric ALL, considering the indications for HSCT and subgroups.

However, our understanding of the regulatory mechanisms governing proneural genes during neuronal differentiation remains limited. RFX4, identified as a candidate regulator of proneural genes, has been reported to be associated with the development of neuropsychiatric disorders.

We examined the control of chlorophyll biosynthesis and protective mechanisms during leaf senescence induced by methyl jasmonate (MeJA). After MeJA treatment, rice plants displayed evidence of great oxidative stress regarding senescence symptoms, disruption of membrane integrity, HO production, and decreased chlorophyll content and photosynthetic efficiency. After 6 h of MeJA treatment, plants greatly decreased not only their levels of chlorophyll precursors, including protoporphyrin IX (Proto IX), Mg-Proto IX, Mg-Proto IX methylester, and protochlorophyllide, but also the expression levels of the chlorophyll biosynthetic genes CHLD, CHLH, CHLI, and PORB, with the greatest decreases at 78 h.

In the lung, electron microscopy studies have suggested that alveolar type-2 epithelial cells (AT2s) en face multiple alveolar sacs. However, apical and basolateral organization of the AT2s and their establishment during development and remodeling after injury repair remain unknown.

Pulmonary hypertension (PH) is a debilitating condition characterized by increased pulmonary arterial pressures and remodeling of pulmonary arteries, leading to right heart failure. Women have a higher prevalence of PH, whereas men have more severe disease and poorer outcomes. Animal models also show female-predominant disease.

Human pluripotent stem cell-derived cerebral organoids (hCOs) are a theoretically infinite source of fresh human brain tissue for various research purposes. However, hCOs have limitations, including core necrotic cell death.

However, not all smokers develop COPD and the critical mechanisms that regulate cellular stress responses to increase COPD susceptibility are not understood. Because microRNAs are well-known regulators of cellular stress responses, we evaluated microRNA expression arrays performed on distal parenchymal lung tissue samples from 172 subjects with and without COPD.

Herein, we clinically investigated the preliminary experience of community-based healthcare program in cases of childhood obesity treated with an herbal complex, Slim-diet (SD), along with lifestyle modification.
Patient Concerns: Seventeen subjects with childhood obesity participated in a community-based healthcare program, which consisted of twice-a-week play type physical activity and dietary counseling program with simultaneous twice-a-day administration of SD for 4 weeks.
It is very important to rapidly detect the contamination of in fermented foods such as Korean Kimchi to maintain its freshness since Kimchi is exported to all over the world. However, gene sequence of is very similar among various . So, there have been difficulties in its screening.

During the photodynamic stress imposed by AF, transcript levels of BjFeCh in transgenic plants increased greatly; moreover, transcript levels of OsFeCh2 remained almost constant, whereas in wild type (WT) plants they were considerably down-regulated. In the heme branch, transgenic plants exhibited greater levels of OsFC and HO transcripts than WT plants in the untreated stems as well as in the AF-treated leaves and stems.

The crystal structure of strontium perchlorate anhydrate, Sr(ClO), was determined and refined from laboratory powder X-ray diffraction data. The material was obtained by dehydration of Sr(ClO)·3HO at 523 K for two weeks. It crystallizes in the ortho-rhom-bic space group and is isotypic with Ca(AlD) and Ca(ClO).

However, the molecular mechanisms via which TLR4 mediates its effect remained unclear. In the present study, we identified distinct contributions of lung endothelial cells (Ec) and epithelial cells TLR4 to pulmonary homeostasis using genetic-specific, lung- and cell-targeted in vivo methods.

This study aimed to evaluate the effects of lowering intraoperative fraction of inspired oxygen on postoperative gas exchange in patients undergoing microvascular decompression (MVD).
Methods: We conducted a pre-post study to compare postoperative gas exchange with different intraoperative oxygen fractions.
The genus Alexandrium often forms harmful algal blooms causing human illness and large-scale mortality of fish and shellfish. Thus, Alexandrium bloom dynamics are primary concerns for scientists, government officials, aquaculture farmers, and the public. To understand bloom dynamics, mortality due to predation needs to be assessed; however, interactions between many Alexandrium species and their potential predators have not previously been reported.

Recently, the heterotrophic nanoflagellate Katablepharis japonica has been reported to be an effective predator of diverse toxic or harmful algal prey. To date, 7 Katablepharis species have been identified, and therefore important questions arise as to whether other Katablepharis species can feed on algal prey, and further whether the types of prey of other Katablepharis species differ from those of K.
