Image_2_Perioperative, functional, and oncological outcomes of robotic vs. laparoscopic partial nephrectomy for complex renal tumors (RENAL score ≥7): an evidence-based analysis.tif
ObjectiveTo evaluate the current literature comparing outcomes of robotic partial nephrectomy (RPN) versus laparoscopic partial nephrectomy (LPN) treating complex renal tumors (RENAL nephrometry score ≥7).MethodsWe systematically searched the Cochrane Library, PubMed, Google Scholar, EMBASE, and Scopus databases up to March 2023. Review Manager 5.4 performed a pooled analysis of the data for random effects. Besides, sensitivity and subgroup analyses to explore heterogeneity, Newcastle-Ottawa scale, and GRADE to evaluate study quality and level of evidence.ResultsEight observational studies comprising 1346 patients (RPN: 695; LPN: 651) were included in this study. Compared to LPN, RPN had a shorter operative time (OT) (weight mean difference [WMD]: -14.73 min; p = 0.0003), shorter warm ischemia time (WIT) (WMD: -3.47 min; p = 0.002), lower transfusion rate (odds ratio [OR]: 0.66; p = 0.04), shorter length of stay (LOS) (WMD: -0.65 days; p ConclusionPatients with complex renal tumors (RENAL score ≥7), RPN is superior to LPN in decreasing the OT, WIT, LOS, transfusion rate, change in eGFR and the incidence of intraoperative complications while maintaining oncological control and avoiding a decline in renal function. However, our findings need further validation in a large-sample prospective randomized study.</p

Investigation of CO<sub>2</sub> Capture in Three-Dimensional Full-Loop Integrated Bubbling-Transport Bed Adsorber
Carbon capture using solid sorbents in fluidized bed
reactors has
attracted increasing attention. However, optimized design and operation
require excellent control over the gas–solid contact and sorbent
circulation between the adsorber and desorber reactors. In this study,
the hydrodynamics and CO2 capture process using potassium-based
solid sorbents in a full-loop integrated system consisting of a bubbling-transport
bed adsorber and a bubbling bed desorber are investigated by using
a three-dimensional two-fluid model (TFM), in which the operating
parameters can be realistically adjusted. Results show that the sorbent
circulation rate increases with the gas velocity in the central pipe
and with the static bed height in the bubbling section of the adsorber.
The pressure distribution, sorbent concentration, and distributions
of the gas and solid velocities are explored, and optimized gas velocities
in the bubbling section and the central pipe are recommended. The
CO2 capture efficiency increases as the water vapor concentration
in the inlet flue gas is increased from 8 to 18%, and the optimal
water vapor concentration is identified as 14%. The results of this
study are useful for the design and optimization of CO2 capture reactors with solid sorbents
CO<sub>2</sub> Capture Performance of Na<sub>2</sub>CO<sub>3</sub>/γ-Al<sub>2</sub>O<sub>3</sub> Sorbent Modified with Organic Acid
Sodium-based sorbents (Na2CO3/γ-Al2O3) hold significant potential for commercial application
in CO2 capture. The key point in optimizing the sorbent
is to enhance its reaction activity and adsorption capacity. This
study utilized organic acids as modifiers for Na2CO3/γ-Al2O3 sorbents and examined
the performance of the sorbents in CO2 capture before and
after modification. The results show that the organic acid modification
plays a crucial role in adjusting the surface hydroxyl groups, reducing
the grain size of the active component, and optimizing the ratio of
high-index crystal surface exposure. The novel sorbent, modified with
citric acid monohydrate, exhibited an exceptional reaction performance.
It achieved a carbonation conversion rate of 88.9% when modified with
citric acid at an equivalent ratio of 2.5, representing a substantial
enhancement of 31% from the bare sample. The organic acid modification
significantly contributes to optimizing the performance of sodium-based
sorbents, thereby advancing their potential for practical CO2 capture applications
