This study aimed to investigate whether driving pressure-guided ventilation can reduce postoperative pulmonary complications in patients who have undergone heart transplantation. Patients who underwent orthotopic heart transplantation were divided into two groups according to the perioperative ventilation strategy: (1) conventional lung-protective ventilation (group C) and (2) driving pressure-guided ventilation (group D). The primary outcome was the occurrence of postoperative pulmonary complications within 30 days of surgery.

Background: Cisplatin triggers Gasdermin E (GSDME) cleavage, causing membrane bubble formation, content release, and inflammation. Caspase-3 activation initiates GSDME cleavage, and thus inhibiting this pathway mitigates cisplatin-induced pyroptosis in hepatocytes. This study aimed to delve into how cisplatin induces liver injury via pyroptosis.

Background: Surgical site infection (SSI) is one of the most common complications after gastric cancer (GC) surgery. The occurrence of SSI can lead to a prolonged postoperative hospital stay and increased medical expenses, and it can also affect postoperative rehabilitation and the quality of life of patients. Subcutaneous fat thickness (SFT) and abdominal depth (AD) can be used as predictors of SSI in patients undergoing radical resection of GC.

Multifunctional photochromic coordination polymers (CPs) have shown great potential in many areas, like molecular switches, anticounterfeiting, magnetics, and optoelectronics. Although multifunctional photochromic CPs can be obtained by introducing photoresponsive functional units or by exploiting the synergy effect of each component, relatively limited photochromic ligands hinder the development of various multifunctional photochromic CPs. In this work, we reported two multifunctional coordination polymers {[Zn(bpdo)(fum)(HO)]} () and {[Mn(bpdo)(fum)(HO)]} () based on an easily accessible but underestimated photoactive molecule 4,4'-bipyridine-'-dioxide ().

Two new disubstituted maleimides, aspergteroids G-H (-), and two trisubstituted butenolides aspergteroids I-J (-), along with four known analogs, were isolated and structurally identified from the fermentation extract of soft-coral-associated symbiotic and epiphytic fungus EGF7-0-1. The structures of the new compounds were established mainly via spectroscopic data analyses, and their absolute configurations were determined via X-ray diffraction analysis and comparison of the calculated and experimental electronic circular dichroism. Myocardial protection assays showed that compounds , , , and possess protective effects against tert-butyl hydroperoxide (TBHP)-induced H9c2 (rat myocardial cells) apoptosis at low concentrations.

Two new indole diketopiperazine alkaloids (IDAs), (+)19-epi-sclerotiamide (1) and (-)19-epi-sclerotiamide (2), along with 13 known analogs (3-15), were isolated from a soft coral-associated epiphytic fungus Aspergillus versicolor CGF 9-1-2. The structures of two new compounds were established based on the combination of HR-ESI-MS, 1D and 2D NMR spectroscopy, optical rotation measurements and quantum chemical C-NMR, the absolute configurations were determined by experimental and electronic circular dichroism (ECD) calculations. The results of molecular docking showed that all the compounds had a good binding with TDP1, TDP2, TOP1, TOP2, Ache, NLRP3, EGFR, EGFR L858R, EGFR T790M and EGFR T790/L858.

Early and sensitive detection of δ-aminolevulinic acid (δ-ALA) and porphobilinogen (PBG) is the cornerstone of diagnosis and effective treatment for acute porphyria. However, at present, the quantifying strategies demand multiple solvent extraction steps or chromatographic approaches to separate δ-ALA and PBG prior to quantification. These methods are both time-consuming and laborious.

The management of eating behavior in bulimia nervosa (BN) patients is a complex process, and BN involves activity in multiple brain regions that integrate internal and external functional information. This functional information integration occurs in brain regions involved in reward, cognition, attention, memory, emotion, smell, taste, vision and so on. Although it has been reported that resting-state brain activity in BN patients is different from that of healthy controls, the neural mechanisms remain unclear and need to be further explored.

Background/aim: Ally lisothiocyanate (AITC), a constituent of naturally occurring isothiocyanates (ITCs) found in some Brassica vegetables, has been previously demonstrated to have anti-carcinogenic activity. However, there is no available information showing that AITC induces DNA damage and alters DNA damage repair proteins in human breast cancer MCF-7 cells.

Materials And Methods: In the present study, we investigated the effects of AITC on DNA damage and repair responses in human breast cancer MCF-7 cells in vitro.

Article Synopsis
  • Single-incision laparoscopic sleeve gastrectomy (SILSG) is proposed as a less invasive option compared to conventional laparoscopic sleeve gastrectomy (CLSG) for obese patients, focusing on comparing surgical outcomes.
  • A meta-analysis of 11 studies involving 1168 patients indicated that SILSG led to higher patient satisfaction regarding cosmetic scars, but there were no significant differences between SILSG and CLSG in other surgical outcomes.
  • The findings suggest SILSG is a viable alternative to CLSG due to its cosmetic benefits, but more high-quality research is needed for definitive conclusions on long-term outcomes.
