Value of early second session shock wave lithotripsy in treatment of upper ureteric stones compared to laser ureteroscopy.

PURPOSE: The safety and efficacy of early second session shock wave lithotripsy (SWL) compared with laser ureteroscopy (URS) for the treatment of upper ureteric stones were evaluated. METHODS: From January to October 2019, 108 patients with upper ureteric stones (< 1.5 cm and ≤ 1000 Hounsfield unit (HU)) were randomized into SWL and laser URS groups. The second SWL session was performed within 48-72 h of the first session. Using plain abdominal X-ray and ultrasonography, patients were evaluated 48-72 h after the first SWL session and one week after the second and third SWL sessions or one week after URS. The procedure was considered a success when no additional procedures were needed to clear the stone. To determine the stone-free rate (SFR), noncontrast computed tomography of the urinary tract was performed three months postoperatively. RESULTS: In the SWL group, the success rates were 92.6% and 94.4% after the second and third sessions. The SFR was 96.2% in the laser URS group. The success rates were not significantly different between the second and third SWL sessions versus the laser URS (p = 0.418 and 0.660, respectively). Operative and fluoroscopy times were significantly longer in the SWL group (p = 0.001), and JJ stent insertions were needed after laser URS. CONCLUSION: Ultraslow full-power SWL treatment of patients with upper ureteric stones (< 1.5 cm and ≤ 1000 HU) with an early second session is safe and effective compared to laser URS. Patients who do not respond to early second SWL session should be shifted to another treatment modality.

Transcriptome Profiling of a Salt Excluder Hybrid Grapevine Rootstock 'Ruggeri' throughout Salinity.

Salinity is one of the substantial threats to plant productivity and could be escorted by other stresses such as heat and drought. It impairs critical biological processes, such as photosynthesis, energy, and water/nutrient acquisition, ultimately leading to cell death when stress intensity becomes uncured. Therefore, plants deploy several proper processes to overcome such hostile circumstances. Grapevine is one of the most important crops worldwide that is relatively salt-tolerant and preferentially cultivated in hot and semi-arid areas. One of the most applicable strategies for sustainable viticulture is using salt-tolerant rootstock such as Ruggeri (RUG). The rootstock showed efficient capacity of photosynthesis, ROS detoxification, and carbohydrate accumulation under salinity. The current study utilized the transcriptome profiling approach to identify the molecular events of RUG throughout a regime of salt stress followed by a recovery procedure. The data showed progressive changes in the transcriptome profiling throughout salinity, underpinning the involvement of a large number of genes in transcriptional reprogramming during stress. Our results established a considerable enrichment of the biological process GO-terms related to salinity adaptation, such as signaling, hormones, photosynthesis, carbohydrates, and ROS homeostasis. Among the battery of molecular/cellular responses launched upon salinity, ROS homeostasis plays the central role of salt adaptation.

Biallelic MAD2L1BP (p31comet) mutation is associated with mosaic aneuploidy and juvenile granulosa cell tumors.

MAD2L1BP-encoded p31comet mediates Trip13-dependent disassembly of Mad2- and Rev7-containing complexes and, through this antagonism, promotes timely spindle assembly checkpoint (SAC) silencing, faithful chromosome segregation, insulin signaling, and homology-directed repair (HDR) of DNA double-strand breaks. We identified a homozygous MAD2L1BP nonsense variant, R253*, in 2 siblings with microcephaly, epileptic encephalopathy, and juvenile granulosa cell tumors of ovary and testis. Patient-derived cells exhibited high-grade mosaic variegated aneuploidy, slowed-down proliferation, and instability of truncated p31comet mRNA and protein. Corresponding recombinant p31comet was defective in Trip13, Mad2, and Rev7 binding and unable to support SAC silencing or HDR. Furthermore, C-terminal truncation abrogated an identified interaction of p31comet with tp53. Another homozygous truncation, R227*, detected in an early-deceased patient with low-level aneuploidy, severe epileptic encephalopathy, and frequent blood glucose elevations, likely corresponds to complete loss of function, as in Mad2l1bp-/- mice. Thus, human mutations of p31comet are linked to aneuploidy and tumor predisposition.
