We develop a new continuous distribution called the beta-Burr type X distribution that extends the Burr type X distribution. The properties provide a comprehensive mathematical treatment of this distribution. Further more, various structural properties of the new distribution are derived, that includes moment generating function and the rth moment thus generalizing some results in the literature. We also obtain expressions for the density, moment generating function and rth moment of the order statistics. We consider the maximum likelihood estimation to estimate the parameters. Additionally, the asymptotic confidence intervals for the parameters are derived from the Fisher information matrix. Finally, simulation study is carried at under varying sample size to assess the performance of this model. Illustration the real dataset indicates that this new distribution can serve as a good alternative model to model positive real data in many areas.

Overexpression of AtbZIP69 in transgenic wheat confers tolerance to nitrogen and drought stress.
Planta
January 2025
State Key Laboratory of Crop Gene Resources and Breeding, Institute of Crop Sciences, Chinese Academy of Agricultural Sciences (CAAS), Beijing, 100081, China.
AtbZIP69 overexpression in wheat significantly enhanced drought and low nitrogen tolerance by modulating ABA synthesis, antioxidant activity, nitrogen allocation, and transporter gene expression, boosting yield. In this study, we generated wheat plants with improved low nitrogen (LN) and drought tolerance by introducing AtbZIP69, a gene encoding a basic leucine zipper domain transcription factor, into the wheat cultivar Shi 4056. AtbZIP69 localized to the nucleus and activated transcription.

Purpose: A finite element analysis was performed to simulate the biomechanical differences between anterior-posterior (AP) direction and posterior-anterior (PA) direction placement of two cannulated screws in Hoffa fractures.
Methods: Computed tomography images of an healthy male volunteer were used to simulate Letenneur Ⅰ, Ⅱa, Ⅱb, Ⅱc, Ⅲ Hoffa fractures, and two groups of screw internal fixation models were constructed. Two 6.
Bowel regimens before radical cystectomy: An analysis of a modern cohort.

Department of Urology, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, Pennsylvania, USA.
Introduction: Bowel regimens (BR) before radical cystectomy (RC) are currently not recommended by Enhanced Recovery After Surgery (ERAS) protocols, as prior studies have shown BRs lead to worsened outcomes. However, many of those studies have used historic literature before recent surgical advancements such as minimally invasive RC and have not investigated the impact BRs have by type of urinary diversion. Our goal is to determine the outcomes of preoperative BR in patients undergoing RC based on diversion type using a modern patient cohort.

Urban rivers are the main water bodies humans frequently come into contact with, so the risks posed are closely monitored. Antibiotic resistance genes (ARGs) residues in reclaimed water pose serious risks to human health. There are urgent needs to improve the understanding of distribution of and risks posed by ARGs in urban rivers.

Tripartite motif-containing proteins (TRIMs), comprising the greatest subfamily of E3 ubiquitin ligases with approximately 80 members of this family, are widely distributed in mammalian cells. TRIMs actively participate in ubiquitination of target proteins, a type of post-translational modification associated with protein degradation and other functions. Tripartite motif-containing protein 29 (TRIM29), a member of the TRIM family, differs from other members of this family in that it lacks the RING finger structural domain containing cysteine and histidine residues that mediates DNA binding, protein-protein interactions, and ubiquitin ligase, at its N-terminus.
