Loin Pain Hematuria Syndrome (LPHS) is a rare condition characterized by cryptogenic debilitating flank pain and microscopic or macroscopic hematuria. The pathophysiology of LPHS remains poorly understood and diagnosis is made largely by exclusion of alternate pathology. Management strategies can vary widely and include chronic opioid medication and a variety of invasive procedures including regional nerve blocks, transcutaneous electrical nerve stimulation, local capsaicin infusion, and surgical renal denervation.

New technological developments have frequently had major consequences for anatomy education, and have raised ethical queries for anatomy educators. The advent of three-dimensional (3D) printing of human material is showing considerable promise as an educational tool that fits alongside cadaveric dissection, plastination, computer simulation, and anatomical models and images. At first glance its ethical implications appear minimal, and yet the more extensive ethical implications around clinical bioprinting suggest that a cautious approach to 3D printing in the dissecting room is in order.

Purpose: Epi-scleral eye plaques provide excellent local control of ocular melanoma, but vision sparing remains a significant problem with 30% or more of patients experiencing significant visual acuity degradation. The use of silicone oil shielding with Iodine-125 plaques has previously been reported to improve critical structure sparing. We hypothesized that the use of Palliadium-103 would improve the shielding effectiveness of silicone oil due to the strong energy dependence of the photoelectric effect. Read More

Research has indicated that Caucasian women gaze more often at waist-hip and chest regions than other local body areas when assessing female body attractiveness and body size, and this stereotypical gaze distribution is further modulated by their own body satisfaction and body composition. However, little is known whether the model race and viewing perspective could affect women's body-viewing gaze behaviour and body perception. Here, we presented female body images of Caucasian, Asian and African avatars in a continuum of common dress sizes in full frontal, mid-profile and rear view, and asked young Caucasian women to rate the perceived body attractiveness and body size.

Landmark experiments in vitro showed that somatic cells can be reprogrammed to stem-cells by the constitutive expression of particular transcription factors. However, in vivo cells naturally exhibit de-differentiation and trans-differentiation programs, thereby suggesting that the signals from the local mechanical microenvironment may be sufficient to induce stem-cell state transitions. In this review, we discuss recent evidence for the biophysical regulation of genome architecture and nuclear programs. Read More

There is growing evidence that the majority of high-grade serous ovarian carcinomas likely arise from local dissemination of precursor lesions of the fallopian tube. Evolution of these lesions from early "p53 signatures" to latter-stage, serous tubal intraepithelial carcinomas (STICs) is characterized by cytologic atypia, accumulation of somatic mutations, and genomic instability, the etiologies of which remain unclear. Long interspersed element 1 (LINE-1) retrotransposon is expressed in many carcinomas, including high-grade serous ovarian carcinoma, where it contributes to genomic instability; however, the timing of LINE-1 activation during this evolution has yet to be elucidated.

The nucleation processes of polyethylene under quiescent and shear flow conditions are comparatively studied with all-atom molecular dynamics simulations. Under both conditions, nucleation is demonstrated to be a two-step process, which, however, proceeds via different intermediate orders. Quiescent nucleation is assisted by local order structures, while flow-induced nucleation is promoted by density fluctuation, which is a coupling effect of conformational and orientational orderings.

Albumin is a highly successful tool of drug delivery providing drastically extended body and blood residence time for the associated cargo, but it only traffics single drug copies at a time. In turn, macromolecular prodrugs (MP) are advantaged in carrying a high drug payload but offering only a modest extension of residence time to the conjugated drugs. In this work, we engineer MP to contain terminal groups that bind to albumin via non-covalent association and reveal that this facile measure affords a significant protraction for the associated polymers.

Testosterone exerts neuroprotective effects on the brain, but the mechanisms by which these effects are exerted appear to be different in males and females. While in females they involve local conversion to estradiol, in males they may be androgen receptor-dependent, or mediated through metabolism to neurosteroids such as 5α-androstane-3α,17β-diol (3α-diol), which acts through different mechanisms than testosterone itself. Recently, we demonstrated that 3α-diol can protect neurons and neuronal-like cells against oxidative stress-induced neurotoxicity associated with prolonged phosphorylation of the extracellular signal-regulated kinase (ERK).
