A study on the thermo-photoisomerization of a liquid crystalline dimer of cyanoazobenzene and naphthalene.

The isomerization kinetics of a liquid crystalline azobenzene dimer, comprising cyanoazobenzene and naphthalene (NAZ6), were investigated at the air-water interface. The Langmuir monolayers of NAZ6 in both its and states were analyzed using surface manometry techniques. The results revealed that NAZ6 molecules in the -state displayed the coexistence of a disordered liquid-expanded phase and an ordered liquid-condensed phase, whereas no such phase transition was observed in the -state.

Left Main Coronary Occlusion During TAVI Procedure: Calcium Embolization Matters.

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is an unwarranted complication associated with high mortality. The current TAVI practices recommend a multidetector computed tomography (MDCT) evaluation of the aortic valve, the left ventricular outflow tract, and the aortic root to determine the conventional risk factors for coronary obstruction like low-lying coronary ostia and narrow sinuses of Valsalva, mandating prophylactic coronary protection or native valve leaflet modification in high-risk patients. Despite optimal anatomy, acute coronary occlusion can still occur due to multiple mechanisms, one of which is coronary embolism due to thrombus, calcium, or native aortic valve fragments.

Unveiling Cannabinoids and Terpenes Diversity in Cannabis sativa L. from Northern India for Future Breeding Strategies.

Cannabis sativa L. is an important medicinal plant with high commercial value. In recent years, the research interest in cannabidiol (CBD) and terpene-rich cannabis has been rapidly expanding due to their high therapeutic potential.

Simultaneous integrated boost intensity-modulated radiation therapy targeting clinically involved extramesorectal lymph nodes in locally advanced rectal cancer: A retrospective study.

Aim: Consensus is lacking regarding the management of extramesorectal lymph nodes (EMLN) in rectal cancer. Using simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT), we targeted involved EMLN and reserved lateral pelvic lymph nodal dissection (LPLND) for nonresponders. The primary aim of this work was to determine the proportion of patients who avoided LPLND and to establish the pathological EMLN positivity rate.

The Impact of Inflammatory Cytokines on Recurrent Pregnancy Loss: A Preliminary Investigation.

Recurrent pregnancy loss (RPL), defined as two or more consecutive miscarriages before 20 weeks of gestation, affects 1-2% of couples worldwide. Pro-inflammatory cytokines, such as TNF-α, IL-1β and IL-6 play critical roles in early pregnancy, while anti-inflammatory cytokines like TGF-β and IL-10 promote immune tolerance to prevent harmful inflammatory responses that play important role in placental and fetal development. This aim of the study is to analyse the levels of inflammatory cytokines in blood serum from RPL patients and healthy women (control).
