N6-methyladenosine (m6A) modification is a common epigenetic modification. It is reported that lncRNA can be regulated by m6A modification. Previous studies have shown that lncRNAs associated with m6A regulation (m6A-lncRNAs) serve as ideal prognostic biomarkers.

Drought-induced forest canopy die-back and tree mortality have been commonly recorded in the lithoid mountainous regions of northern China. However, the capacity of trees to regulate their carbon and water balance in response to drought remains inadequately understood. We measured tree growth, intrinsic water use efficiency (iWUE), vulnerability, and canopy health during drought events using dendrochronology, C isotope measurements, and a tree canopy health survey in a mixed plantation of and .

Article Synopsis
  • Understanding tree growth and drought response in Mongolian pines is essential for managing plantation forests, especially considering competition among trees.
  • The study analyzed the growth of these pines using tree-ring data in various forests, indicating that higher competition resulted in significantly lower growth rates after several years.
  • Key climatic factors like precipitation and humidity influenced growth more than competition overall, but higher competition stands showed reduced resilience to drought, suggesting a higher risk of tree mortality in the future.

We evaluated the adaptability of Granier's empirical formula in the measurement of trunk sap flow in Populus tomentosa. The thermal diffusion probe method (TDP) was used to mea-sure sap flow rate, and the whole tree weighing was simultaneously measured for each tree. We compared results from the Granier empirical formula with that from the whole tree weighing to find out whether Granier formula had any error in measuring the trunk sap flow of P.

  • Kilometer-scale evapotranspiration is typically estimated using remote sensing images alongside models and validated with ground data, but real-time measurement at pixel scale is challenging.
  • A study conducted at the Ecosystem Research Station of the Yellow River combined near-infrared and microwave techniques to analyze evapotranspiration during plantation growth from July to October 2016, achieving a strong energy balance of 0.87.
  • The method proved sensitive to air humidity variations but not to soil moisture, and compared to eddy covariance measurements, estimated daily and total evapotranspiration were 3.5 mm and 162.4 mm, respectively, with reasonable errors attributed to Bowen ratios and atmospheric stability.

Objective: To summarize the features and treatment of male infertility induced by autosomal dominant polycystic kidney disease (ADPKD), and compare the outcomes of intracytoplasmic sperm injection (ICSI) for infertile men with ADPKD and those with congenital bilateral absence of vas deferens (CBAVD).

Methods: We retrospectively analyzed 21 cases of ADPKD-induced infertility, 15 treated by ICSI (group A), and another 164 cases of strictly matched CBAVD-induced infertility (group B). We compared the two groups in the couples' age, the number of ICSI oocytes, and the rates of fertilization, transferrable embryos, good embryos, embryos implanted, clinical pregnancy, biochemical pregnancy, early abortion, singleton and twins in the first cycle.

Objective: To evaluate the effect of adjuvant hormonal therapy (AHT) immediately after radical surgery for high- risk organ-confined or locally advanced prostate cancer using the PSA-related biochemical relapse rate within 2 years after surgery.

Methods: We retrospectively analyzed 62 cases of high-risk organ-confined or locally advanced prostate cancer. The patients were treated by laparoscopic radical prostatectomy or radical retropubic prostatectomy after MRI and ECT systemic bone imaging examination, which revealed no regional lymph node or bone metastasis.

The purpose of this study was to describe a new simplified technique for facilitating vesicourethral anastomosis in laparoscopic radical prostatectomy. After prostate removal, an approximately 15-cm-long absorbable suture with one three-eighths arc needle is passed from the outside in on the full thickness of the bladder neck at the 9 o'clock position and then from inside out on the full thickness of the urethra at the 9 o'clock position. It is knotted with the suture tail.

Peptidyl-prolylcis-trans isomerase NIMA-interacting 1 (encoded by the gene) regulates the conformation of proline-directed phosphorylation sites and is important in the etiology of cancer. Since the identification of a functional polymorphism of -842 G>C; rs2233678), in the promoter region, numerous studies have evaluated the association between the promoter polymorphism (-842 G>C) and cancer risk. However, the available results are inconclusive.

Deficiencies in tricarboxylic acid (TCA) cycle enzymes have been shown to cause a wide spectrum of human diseases, including malignancies and neurological and cardiac diseases. In mammalian spermatozoa mitochondria, the TCA cycle is known to be a crucial metabolic pathway that contributes to produce ATP. There is little known about the role and mechanism of mitochondrial aconitase (ACO2), which is an important regulatory enzyme of the TCA cycle, in asthenozoospermia.

Objective: To investigate the clinical characteristics and surgical treatment of penile Paget's disease.

Methods: We retrospectively analyzed the treatment and follow-up data of 10 cases of penile Paget's disease surgically treated in Jiangsu Provincial Government Hospital and Jiangsu Provincial People's Hospital from 2008 to 2012.

Results: All the 10 patients received expanded local resection of the lesion with reconstruction of the defects with scrotal skin flaps or free skin flaps from the thigh.

Background: MicroRNA-221 (miR-221) has been shown to play an important role in cancer prognosis. In order to evaluate the predictive value of miR-221, we compiled the evidence from 20 eligible studies to perform a meta-analysis.

Design: All of relevant studies were identified by searching PubMed, Embase, and Web of Science, and were assessed by further quality evaluation.

Article Synopsis
  • The study aimed to investigate how microRNA-205 (miR-205) acts as a tumor suppressor in prostate cancer (PCa), revealing that its expression decreases significantly in advanced stages compared to early stages of cancer.
  • Analysis showed that lower miR-205 levels are correlated with more severe clinicopathological features and higher PSA levels in PCa patients.
  • Functional experiments demonstrated that increasing miR-205 or reducing c-SRC in cancer cell lines inhibited various cancer behaviors like growth and invasion, while also identifying c-SRC as a target of miR-205 that impacts cancer-related signaling pathways.

  • HIF-1α is crucial for angiogenesis, affecting tumor growth and metastasis, and genetic variations in HIF1A can influence cancer susceptibility.
  • A study involving 662 prostate cancer patients and 716 controls found that certain HIF1A polymorphisms (particularly rs11549467) were linked to a significantly higher risk of developing prostate cancer.
  • Specifically, those with the rs11549467 variant had increased risk based on factors like age, smoking status, and family history, as well as a correlation to higher Gleason scores, indicating more aggressive cancer.

Current surgical treatment of prostate cancer is typically accomplished by either open radical prostatectomy (ORP) or robotic-assisted laparoscopic radical prostatectomy (RALRP). Intra-operative procedural differences between the two surgical approaches may alter the molecular composition of resected surgical specimens, which are indispensable for molecular analysis and biomarker evaluation. The objective of this study is to investigate the effect of different surgical procedures on RNA quality and genome-wide expression signature.
