Cohort profile: a migratory cohort study of US Marines who train in Australia.

Purpose: In 2012, US Marines and Sailors began annual deployments to Australia to participate in joint training exercises with the Australian Defence Force and other partners in the region. During their training, US service members are exposed to a variety of infectious disease threats not normally encountered by American citizens. This paper describes a cohort of US Marines and Sailors enrolled during five rotations to Australia between 2016 and 2020.

Elevated AKR1C3 expression promotes prostate cancer cell survival and prostate cell-mediated endothelial cell tube formation: implications for prostate cancer progression.

Background: Aldo-keto reductase (AKR) 1C family member 3 (AKR1C3), one of four identified human AKR1C enzymes, catalyzes steroid, prostaglandin, and xenobiotic metabolism. In the prostate, AKR1C3 is up-regulated in localized and advanced prostate adenocarcinoma, and is associated with prostate cancer (PCa) aggressiveness. Here we propose a novel pathological function of AKR1C3 in tumor angiogenesis and its potential role in promoting PCa progression.

Suppressed expression of type 2 3alpha/type 5 17beta-hydroxysteroid dehydrogenase (AKR1C3) in endometrial hyperplasia and carcinoma.

The diagnosis of endometrial hyperplasia and endometrial type adenocarcinoma arising within the uterine cavity has long been rested on morphologic criteria. Although distinction between normal endometrial epithelium from adenocarcinoma is usually straightforward, the separation between normal and hyperplastic endometrium, particularly those cases without atypia, can be a diagnostic challenge. The same is true in separation of hyperplastic endometrium with atypia from endometrial-type endometrial adenocarcinoma.

Expression of AKR1C3 in renal cell carcinoma, papillary urothelial carcinoma, and Wilms' tumor.

Human aldo-keto reductase (AKR) 1C3 is a monomeric cytoplasmic multifunctional enzyme that reduces ketosteroids, ketoprostaglandins, and lipid aldehydes. AKR1C3 was initially identified as an enzyme involved in steroid metabolism. However, immunohistochemistry has demonstrated AKR1C3 in normal adult kidneys with expression in Bowman' capsule, the mesangial cells, proximal and distal tubules, as well as mature urothelial epithelium.

Reliability and limitations of the durometer and PressureStat to measure plantar foot characteristics in Native Americans with diabetes.

Neuropathy with excessive weight-bearing activity may lead to foot changes that place it at risk for ulceration. Information about instruments to measure plantar skin hardness and pressures of the foot in adult Native Americans with diabetes is presented. Skin hardness was measured at 10 sites (plantar side of the hallux, third and fifth toes, first, third, and fifth metatarsal heads, medial and lateral midfoot, heel, and the dorsal aspect between the hallux and second toe) with a durometer.

Age-dependent vascular endothelial growth factor expression and angiogenic capability of bladder smooth muscle cells: implications for cell-seeded technology in bladder tissue engineering.

Cell seeding technology is commonly used in the field of tissue engineering to enhance the performance of bioscaffolds and promote tissue regeneration. The age of cells used for ex vivo seeding to achieve maximal tissue regeneration has not been defined. Since rapid angiogenesis is the most critical step for tissue graft survival and success, we evaluated passage-dependent vascular endothelial growth factor (VEGF) expression in cultured smooth muscle cells (SMCs) obtained from urinary bladder and endothelial cell response to bladder SMCs.

Frankincense oil derived from Boswellia carteri induces tumor cell specific cytotoxicity.

Background: Originating from Africa, India, and the Middle East, frankincense oil has been important both socially and economically as an ingredient in incense and perfumes for thousands of years. Frankincense oil is prepared from aromatic hardened gum resins obtained by tapping Boswellia trees. One of the main components of frankincense oil is boswellic acid, a component known to have anti-neoplastic properties.

Tissue distribution of human AKR1C3 and rat homolog in the adult genitourinary system.

Human aldo-keto reductase (AKR) 1C3 (type 2 3alpha-hydroxysteroid dehydrogenase/type 5 17beta-hydroxysteroid dehydrogenase) catalyzes androgen, estrogen, and prostaglandin metabolism. AKR1C3 is therefore implicated in regulating ligand access to the androgen receptor, estrogen receptor, and peroxisome proliferator activating receptor gamma in hormone target tissues. Recent reports on close relationships between ARK1C3 and various cancers including breast and prostate cancers implicate the involvement of AKR1C3 in cancer development or progression.

Assessment of angiogenic properties of biomaterials using the chicken embryo chorioallantoic membrane assay.

The angiogenic potential of a biomaterial is a critical factor for successful graft intake in tissue engineering. We developed a modified, rapid and reproducible chicken embryo chorioallantoic membrane (CAM) assay to evaluate the ability of biomaterials in inducing blood vessel density. Five biomaterials including one-layer porcine small intestinal submucosa (SIS), two-layer SIS, four-layer vacuum pressed (VP) SIS, polyglycolic acid (PGA) and PGA modified with poly(lactic-co-glycolic acid) (PLGA) were analyzed.
