Classification and Treatment Strategies of Tibial Tubercle Fractures in Adults.

Objectives: Tibial tubercle is a crucial player in maintaining the structural integrity and functional stability of the knee joint. Currently, there is no standardized protocol for the classification and treatment of tibial tubercle fractures in adults. This study analyzed the incidence and treatment strategies of tibial tubercle fractures in adults according to the four-column and nine-segment classification system.

Oncological impact of different distal ureter managements during radical nephroureterectomy for primary upper urinary tract urothelial carcinoma.

Background: The current standard surgical treatment for non-metastatic upper urinary tract urothelial carcinoma (UTUC) is radical nephroureterectomy (RNU) with bladder cuff excision (BCE). Typically, BCE techniques are classified in one of the following three categories: An open technique described as intrasvesical incision of the bladder cuff, a transurethral incision of the bladder cuff (TUBC), and an extravesical incision of the bladder cuff (EVBC) method. Even though each of these management techniques are widely used, there is no consensus about which surgical intervention is superior, with the best oncologic outcomes.

Comparing the Oncological Outcomes of Cryoablation vs. Radical Prostatectomy in Low-Intermediate Risk Localized Prostate Cancer.

To compare the oncologic outcomes of cryoablation (CA) and radical prostatectomy (RP) in patients with low- and intermediate-risk localized prostate cancer (PCa). PCa patients who received CA or RP between 2004 and 2015 were identified from the Surveillance, Epidemiology, and End Results database. Multivariable Cox proportional hazard analysis was used to compare the prostate cancer-specific survival (CSS) and overall survival (OS).

Intrathecal versus local infiltration analgesia for pain control in total joint arthroplasty.

Background: The purpose of this meta-analysis was to assess the efficacy of intrathecal morphine (ITM) analgesia and local infiltration analgesia (LIA) for pain control in total joint arthroplasty (TJA).

Methods: Embase, PubMed, the Cochrane Library, and Web of Science were systematically searched for randomized controlled trials (RCTs). All RCTs were comparing intrathecal analgesia and local infiltration analgesia in TJA.

Synthesis and anti-cancer activity of ND-646 and its derivatives as acetyl-CoA carboxylase 1 inhibitors.

Acetyl-coA carboxylase 1 (ACC1) is the first and rate-limiting enzyme in the de novo fatty acid synthesis (FASyn) pathway. In this study, through public database analysis and clinic sample test, we for the first time verified that ACC1 mRNA is overexpressed in non-small-cell lung cancer (NSCLC), which is accompanied by reduced DNA methylation at CpG island S shore of ACC1. Our study further demonstrated that higher ACC1 levels are associated with poor prognosis in NSCLC patients.

Prolonged milk provisioning in a jumping spider.

Lactation is a mammalian attribute, and the few known nonmammal examples have distinctly different modalities. We document here milk provisioning in a jumping spider, which compares functionally and behaviorally to lactation in mammals. The spiderlings ingest nutritious milk droplets secreted from the mother's epigastric furrow until the subadult stage.

Genotype and phenotype correlation in von Hippel-Lindau disease based on alteration of the HIF-α binding site in VHL protein.

Purpose: Von Hippel-Lindau (VHL) disease is a rare hereditary cancer syndrome that reduces life expectancy. We aimed to construct a more valuable genotype-phenotype correlation based on alterations in VHL protein (pVHL).

Methods: VHL patients (n = 339) were recruited and grouped based on mutation types: HIF-α binding site missense (HM) mutations, non-HIF-α binding site missense (nHM) mutations, and truncating (TR) mutations.

Risk factors for survival in patients with von Hippel-Lindau disease.

Background: Historically, von Hippel-Lindau (VHL) disease is characterised by a poor survival. Although genotype-phenotype correlation has been described in many studies, the risk factors for VHL survival remain unclear. This study aims to evaluate the median survival of Chinese patients with VHL disease and explore whether VHL survival is influenced by genetic and clinical factors.

Shorter telomere length increases age-related tumor risks in von Hippel-Lindau disease patients.

Von Hippel-Lindau (VHL) disease is a rare autosomal dominant cancer syndrome caused by alterations of VHL gene. Patients are predisposed to develop pheochromocytomas and solid or cystic tumors of the central nervous system, kidney, pancreas, and retina. Remarkable phenotypic heterogeneity exits in organ involvement and tumor onset age between and within VHL families.

Single-chain antibody against human lipocalin-type prostaglandin D synthase: construction, expression, purification, and activity assay.

An active form of single-chain antibody (ScFv) from murine monoclonal antibody 4A7, which is specific for lipocalin-type prostaglandin D synthase (L-PGDS), was produced in Escherichia coli. The complementary DNA fragments encoding the variable regions of heavy chain (VH) and light chain (VL), which amplified from hybridoma 4A7 producing a monoclonal antibody (IgG1) against L-PGDS, were connected by a (Gly4Ser)3 linker using an assembly polymerase chain reaction. The resultant ScFv were cloned into the vector pGEM and expressed in E.

Different expression of lipocalin-type prostaglandin D synthase in rat epididymidis.

This study was designed to explore the different expression of L-PGDS (lipocalin-type prostaglandin D synthase) in rat epididymidis and to gain further insight into the potential function of L-PGDS in male reproduction. The expression of L-PGDS in rat epididymidis was assessed using real-time quantitative PCR and immunoblotting. The distribution of L-PGDS in rat epididymidis was explored by immunohistochemical methods.
