Background: The aim of this prospective study was to compare the effect of application of nitroglycerin and verapamil solution (GV) by organ bath technique with other methods of applications and solutions on the free blood flow of LITA. The technique was not described for in situ graft before.
Method: The patients were randomly assigned to four groups: group I (n_32, GV solution by organ bath technique), group II (n_30, papaverine solution by organ bath technique), group III (n_29, topical GV solution) or group IV (n_29, topical papaverine solution). In each patient, pedicled LITA was harvested; thereafter applied with the randomized different methods and solutions. The free flow from the distal end of the divided LITA was measured for 15s under controlled hemodynamic conditions after harvesting (Flow 1). The flow of LITA was measured again just prior to anastomosing the conduit (Flow 2).
Result: The mean blood flow in LITA was 56.2±5.0ml/min before application of solutions. After application, the mean blood flow in group I:102.3±7.0ml/min, in group II: 92.7±3.4ml/min, and in group III: 88.6±2.2ml/min and in group IV: 81.4±2.1. Proportional increases in blood flow observed in group I (82.6%)>group II (65.1%)>group III (57.6)>group IV (44.8%) (p<0.05).
Conclusions: GV solution by organ bath technique is effective and superior in comparison to use of papaverine using organ bath technique or topical spray of GV or papaverine solution.

Soft tissue sarcomas (STSs) are rare malignancies, with retroperitoneal soft tissue sarcoma (RPS) constituting 10%-15% of all STSs. RPS often presents late due to minimal early symptoms, typically requiring complete en-bloc resection for optimal survival outcomes. Achieving radical resection can be challenging due to the tumor's proximity to vital organs.

Water pollution because of the presence of heavy metals remains a serious worry. The present work demonstrates the exclusion of cobalt ion (or Co(II)) from water using novel and cost-effective biosorbents. Initially, the biosorbent was chemically modified using orthophosphoric acid and then subjected to calcination to result acid modified date seed biochar (AMDB).

Chlorophyll (Chl) is the most abundant light-harvesting pigment of oxygenic photosynthetic organisms; however, the Q-band energetics and relaxation dynamics remain unclear. In this work, we have applied femtosecond time-resolved (-TA) absorption spectroscopy in 430-1,700 nm to Chls and in diluted pyridine solutions under selective optical excitation within their Q-bands. The results revealed distinct near-infrared absorption features of the B ← Q and B ← Q transitions in 930-1,700 nm, which together with the steady-state absorption in 400-700 nm unveiled the Q-state energy that lies 1,000 ± 400 and 600 ± 400 cm above the Q-state for Chls and , respectively.

Over the past two decades, research into the accumulation of small plastic particles and fibers in organisms and environmental settings has yielded over 7,000 studies, highlighting the widespread presence of microplastics in ecosystems, wildlife, and human bodies. In recent years, these contaminants have posed a significant threat to human, animal, and environmental health, with most efforts concentrated on removing them from aquatic systems. Given this urgency, the purpose of this study was to investigate the potential of rhamnolipid, a biosurfactant, for the removal of microplastics from water.

Cryptobiosis is a state where organisms lose nearly all their internal water and enter anhydrobiosis under extreme environmental stress. The dispersal third-stage juveniles (pre-dauer juveniles, ) of Bursaphelenchus xylophilus can enter cryptobiosis through dehydration and revive upon rehydration when environmental conditions improve. Osmotic regulation is crucial for their survival in this process.
