The Role of Neuromodulation in Chronic Pelvic Pain: A Review Article.

Background: Chronic pelvic pain (CPP) is a complex, heterogeneous condition affecting both female and male patients with significant effects on quality of life. Chronic pelvic pain is a prevalent but often underdiagnosed condition due to the variation in patient presentation, a gap in communication among specialties, under-reporting of the syndrome, and lack of standardized diagnostic criteria with a subsequent delay in diagnosis. The mechanism of CPP is complex due to multifactorial etiologies of pain and its vast anatomy and innervation.

Gene-teratogen interactions influence the penetrance of birth defects by altering Hedgehog signaling strength.

Birth defects result from interactions between genetic and environmental factors, but the mechanisms remain poorly understood. We find that mutations and teratogens interact in predictable ways to cause birth defects by changing target cell sensitivity to Hedgehog (Hh) ligands. These interactions converge on a membrane protein complex, the MMM complex, that promotes degradation of the Hh transducer Smoothened (SMO).

Alternative Implantation Site of Intrathecal Pump in the Submuscular Plane of the Pectoralis Major Muscle: A Case Report.

An intrathecal drug delivery system (IDDS) has been widely utilized in the management of chronic pain and spasticity when oral pharmacologic agents are deemed ineffective. Typically, intrathecal pumps are implanted in the abdominal region; however, previous case reports have described nontraditional pump implantation sites, such as anterior thigh, gluteal region, and iliac fossa. Adding to the growing literature of alternative implantation sites, this case report discusses the implantation of the pump into the submuscular plane of the pectoralis major muscle and reviews the advantages and disadvantages of this location.

Linkage of resistance-associated substitutions in GT1 sofosbuvir + NS5A inhibitor failures treated with glecaprevir/pibrentasvir.

Background & Aims: Retreatment with glecaprevir/pibrentasvir (G/P) resulted in a rate of sustained virologic response 12 weeks after treatment completion (SVR12) of >90% in HCV genotype 1 (GT1) patients who previously failed a regimen of sofosbuvir plus an NS5A inhibitor (NS5Ai). This study investigated the prevalence and impact of baseline NS3 and NS5A resistance-associated substitutions (RASs) on the efficacy of G/P in prior GT1 sofosbuvir+NS5Ai failures and the persistence of treatment-emergent RASs.

Methods: Longitudinal samples from 177 patients enrolled in a phase IIIb, randomized pragmatic clinical trial were analyzed.

A Membrane-Tethered Ubiquitination Pathway Regulates Hedgehog Signaling and Heart Development.

The etiology of congenital heart defects (CHDs), which are among the most common human birth defects, is poorly understood because of its complex genetic architecture. Here, we show that two genes implicated in CHDs, Megf8 and Mgrn1, interact genetically and biochemically to regulate the strength of Hedgehog signaling in target cells. MEGF8, a transmembrane protein, and MGRN1, a RING superfamily E3 ligase, assemble to form a receptor-like ubiquitin ligase complex that catalyzes the ubiquitination and degradation of the Hedgehog pathway transducer Smoothened.

Autophagy gene haploinsufficiency drives chromosome instability, increases migration, and promotes early ovarian tumors.

Autophagy, particularly with BECN1, has paradoxically been highlighted as tumor promoting in Ras-driven cancers, but potentially tumor suppressing in breast and ovarian cancers. However, studying the specific role of BECN1 at the genetic level is complicated due to its genomic proximity to BRCA1 on both human (chromosome 17) and murine (chromosome 11) genomes. In human breast and ovarian cancers, the monoallelic deletion of these genes is often co-occurring.

Haploinsufficiency networks identify targetable patterns of allelic deficiency in low mutation ovarian cancer.

Identification of specific oncogenic gene changes has enabled the modern generation of targeted cancer therapeutics. In high-grade serous ovarian cancer (OV), the bulk of genetic changes is not somatic point mutations, but rather somatic copy-number alterations (SCNAs). The impact of SCNAs on tumour biology remains poorly understood.

Nelfinavir is effective against human cervical cancer cells in vivo: a potential treatment modality in resource-limited settings.

Objective: The standard treatment for cervical cancer in developed countries includes surgery and chemoradiation, with standard of care lagging in developing countries. Even in the former case, treatment frequently yields recalcitrant tumors and women succumb to disease. Here we examine the impact of nelfinavir, an off-patent viral protease inhibitor, which has shown promise as an antineoplastic agent.

Validation of dbEST-SSRs and transferability of some other solanaceous species SSR in ashwagandha [Withania Somnifera (L.) Dunal].

Cross-species transferability and expressed sequence tags (ESTs) in public databases are cost-effective means for developing simple sequence repeats (SSRs) for less-studied species like medicinal plants. In this study, 11 EST-SSR markers developed from 742 available ESTs of Withania Somnifera EST sequences and 95 SSR primer pairs derived from other solanaceous crops (tomato, eggplant, chili, and tobacco) were utilized for their amplification and validation. Out of 11, 10 EST-SSRs showed good amplification quality and produced 13 loci with a product size ranging between 167 and 291 bp.
