Toxoplasma gondii infects a wide range of hosts worldwide, including humans and domesticated animals causing toxoplasmosis disease. Recently, exosomes, small extracellular vesicles (EV) that contain nucleic acids, proteins, and lipids derived from their original cells were linked with disease protection. The effect of EVs derived from T. gondii on the immune response and its relevance in a physiological context is unknown. Here we disclose the first proteomic profiling of T. gondii EVs compared to EVs isolated from a human foreskin fibroblast infected cell line cultured in a vesicle- free medium...

In this paper, I examine disputes over recent claims that male circumcision reduces HIV risk to suggest a complicated relationship between risk individualization and categorization. Whereas randomized controlled trials (RCTs) conducted in sub-Saharan Africa appear to have provided key evidence for the World Health Organization's endorsement of male circumcision as an HIV prevention strategy, RCTs alone did not provide evidence for the underlying causal mechanism. For that, medical authorities have turned to histo-immunological studies of the foreskin's biomolecular vulnerability to HIV, thus molecularizing risk...

OBJECTIVES: We observed whether general practitioners are referring more appropriately for balanitis xerotica obliterans in regards to circumcision, especially at a time of clinical concern, and whether their discriminative abilities were affected by age. We also aimed to explore if balanitis xerotica obliterans was over-diagnosed by surgeons potentially leading to unnecessary circumcisions of healthy foreskins. DESIGN: Cross-sectional descriptive study. SETTING: Leicester Royal Infirmary...

Candida species causes superficial and life-threatening systemic infections and are difficult to treat due to the resistance of these organism to various clinically used drugs. Protolichesterinic acid is a well-known lichen compound. Although the antibacterial activity of protolichesterinic acid has been reported earlier, the antifungal property and its mechanism of action are still largely unidentified. The goal of the present investigation is to explore the anticandidal activity and mechanism of action of protolichesterinic acid, especially against Candida tropicalis...

Many aspects of the HPV life cycle have been characterized in cervical cell lines (W12, CIN612) and in HPV immortalized primary foreskin keratinocytes. There is now an epidemic of HPV positive oropharyngeal cancers (HPV16 is responsible for 80-90% of these); therefore increased understanding of the HPV16 life cycle in oral keratinocytes is a priority. To date there have been limited reports characterizing the HPV16 life cycle in oral keratinocytes. Using TERT immortalized "normal" oral keratinocytes (NOKs) we generated clonal cell lines maintaining the HPV16 genome as an episome, NOKs+HPV16...

ETHNOPHARMACOLOGICAL RELEVANCE: The discovery of many tissue-specific cancer stem cells (CSCs) continues to attract scientific attention. These CSCs are considered to be associated with chemo- and radio-resistance, and consequently, failure of conventional anticancer therapies. The recent demonstration of several microRNAs as enhancers of tumorigenicity via modulation of epithelial-mesenchymal transition and cancer stemness, makes them putative novel therapeutic target in oncology. Antrodia cinnamomea is a Chinese traditional medicine with several biological functions including anti-inflammation, antioxidant, and cancer prevention...

Chrysin (Chr) is a naturally occurring flavone with a wide spectrum of biological functions including anti-cancer, anti-inflammatory and anti-oxidant properties. Due to the low bioavailability and in vivo stability of Chr at therapeutic levels for wound-healing applications, Chr-loaded PCL/PEG nanofibrous mats were successfully fabricated by optimizing the electrospinning parameters and characterized using FE-SEM and FTIR. Results of MTT showed that Human foreskin fibroblast cells (HFF-1) have more than 80% viability on Chr-loaded nanofibers...

The skin wounds caused by insults should be treated immediately to restore the functions and integrity. Recent studies suggest that stem cells-based therapies may be applicable in wound healing. Newly defined menstrual blood-derived stem cells (MenSCs) show high rate of cell proliferation and trans-differentiation potency to various cell types. However, MenSCs potential to generate keratinocyte for future therapeutic use of skin lesions has been remained to investigate. We cultivated MenSCs in the presence of isolated foreskin derived-keratinocytes using an indirect co-culture system and evaluated efficiency of this protocol to generate keratinocytes using immunofluorescent staining and Real Time PCR technique...

This study endeavors to analyze the effects of thermocautery, bipolar cautery, monopolar cautery, and the scalpel to show that the thermocautery is a safe device to be used in circumcision. Twenty-four rats were assigned to 4 different groups: the scalpel, thermocautery, bipolar cautery, and monopolar cautery groups. Circumcisions were performed using the scalpel, thermocautery, bipolar cautery, or monopolar cautery devices. The circumcised foreskin was removed for histopathological analysis. The circumcision techniques were compared in terms of the depth of injury on the prepuce...

Orf virus has been utilized as a safe and efficient viral vector against not only diverse infectious diseases, but also against tumors. However, the nature of the genes triggered by the vector in human cells is poorly characterized. Using RNA sequencing technology, we compared specific changes in the transcriptomic profiles in human foreskin fibroblast cells following infection by the orf virus. The results indicated that orf virus upregulates or downregulates expression of a variety of genes, including genes involved in antiviral immune response, apoptosis, cell cycle and a series of signaling pathways, such as the IFN and p53-signaling pathways...

Ultraviolet (UV) radiation is the primary risk factor underlying photoaging and photocarcinogenesis. Mounting research has focused on the role of DNA damage response pathways in UV-induced double-strand break (DSB) repair. In the present study, we hypothesized that UVA-induced aberrant progerin upregulation may adversely affect p53-binding protein 1 (53BP1)-mediated non-homologous end joining (NHE) DSB repair in human keratinocytes. Basal cell carcinoma (BCC) tumors and matching normal skin tissue were sampled (n=200) to investigate whether human keratinocytes display dysregulated progerin expression as a function of advancing age and BCC status...

Adiponectin, an adipocyte-derived hormone, exerts pleiotropic biological effects on metabolism, inflammation, vascular homeostasis, apoptosis and immunity. Recently, adiponectin has been suggested to attenuate the progression of human dermal fibrosis. Connective tissue growth factor (CTGF) is induced in keloids and is thought to be participated in the formation of keloid fibrosis. However, the roles played by adiponectin in keloids remain unclear. In this study, we explored the effects of adiponectin on CTGF-induced cell proliferation, migration and the deposition of extracellular matrix (ECM) and their associated intracellular signalling pathways in keloid fibroblasts (KFs)...

We have previously reported that human neonatal foreskin stromal cells (hNSSCs) promote angiogenesis in vitro and in chick embryo chorioallantoic membrane (CAM) assay in vivo. To examine the in vivo relevance of this observation, we examined in the present study the differentiation potential of hNSSCs in ex vivo organotypic cultures of embryonic chick femurs. Isolated embryonic chick femurs (E10 and E11) were cultured for 10 days together with micro-mass cell pellets of hNSSCs, human umbilical vein endothelial cells (HUVEC) or a combination of the two cell types...

Elevated birth weight is linked to glucose intolerance and obesity health-related complications later in life. No studies have examined if infant birth weight is associated with gene expression markers of obesity and inflammation in a tissue that comes directly from the infant following birth. We evaluated the association between birth weight and gene expression on fetal programming of obesity. Foreskin samples were collected following circumcision, and gene expression analyzed comparing the 15% greatest birth weight infants (n=7) v...

Background: Staphylococcus epidermidis, a major component of skin flora, is an opportunist, often causing prosthetic device infections. A family of structurally-related proteins mediates staphylococcal attachment to host tissues, contributing to the success of S. epidermidis as a pathogen. We examined the ability of the surface protein SdrF to adhere to keratin, a major molecule expressed on the skin surface. Methods: A heterologous Lactococcus lactis expression system was used to express SdrF and its ligand binding domains...
