Traditional male circumcision (TMC) is a cultural ritual that involves the removal of the penile foreskin of a male person undertaken as part of a rite of passage from childhood into adulthood. The aim of the study was to determine the notions of manhood in TMC by African adolescent boys in Ngove Village, Limpopo Province. This was a qualitative study that sampled a total of 20 adolescent boys through purposive sampling. Data were collected using semistructured interviews and analyzed through interpretive phenomenological analysis (IPA)...

Background: Phimosis is a condition in which the foreskin cannot be portrayed on the glans. It is a physiological and common condition in the pediatric age. The pathological form derives from an inflammatory or traumatic lesion. Circumcision is the most common surgical treatment of phimosis but it is a controversial practice, especially in occidental world. Methods: We enrolled 61 patients with pathological phimosis (22/balanoposthitis, 18/painful erection, 21/urinary discomfort) between 2015-2017...

Polydimethylsiloxane (PDMS) is a promising biomaterial for generating artificial extracellular matrix (ECM) like patterned topographies, yet its hydrophobic nature limits its applicability to cell-based approaches. Although plasma treatment can enhance the wettability of PDMS, the surface is known to recover its hydrophobicity within a few hours after exposure to air. To investigate the capability of a novel PDMS-type (X-PDMS) for in vitro based assessment of physiological cell properties, we designed and fabricated plane as well as nano- and micrometer-scaled pillar-patterned growth substrates using the elastomer types S-, H- and X-PDMS, which were fabricated from commercially available components...

The prognosis of anaplastic (ATC) and poorly differentiated thyroid cancer (PDTC) is poor, due to their radioiodine refractoriness (RAI-R), high metastatic potential and current lack of effective treatment strategies. We aimed to examine the efficacy of the tyrosine kinase inhibitors (TKIs) sorafenib and selumetinib and the histone deacetylase inhibitor (HDACI) panobinostat in patient-derived tumor tissue (PDTT) of ATCs/PDTCs, the expression of sodium iodide symporter ( NIS ) and radioiodine up-take (RAI-U)...

Regeneration of full-thickness wound without scar formation is a multifaceted process which depends on in situ dynamic interactions between the tissue-engineered skin substitutes and newly formed reparative tissue. However, the majority of the tissue-engineered skin substitutes used so far in full-thickness wound healing cannot mimic the natural extracellular matrix (ECM) complexity and thus are incapable of providing a suitable niche for endogenous tissue repair. Herein, we demonstrated a simple approach to fabricate porous Hybrid Extracellular Matrix Sponges (HEMS) using Placental Extracellular Matrix (pECM) and Silk Fibroin (SF) for full-thickness wound healing...

Overexpression of GRP78 in a variety of cancers such as glioblastoma, leukaemia, lung, prostate, breast, gastric, and colon makes it a prime target for anticancer drug development. Present study reports GRP78-based design of novel anticancer agents using in silico methods. As a first step towards the work, the interactions between GRP78 and 15 known ligands were modeled by docking simulation. The docked complex, GRP78-13, superior to other compounds with respect to its experimental activity and energy descriptors, was deduced into a structure-based pharmacophore...

Human cytomegalovirus (HCMV) is a major cause of disease in immunocompromised individuals and the most common cause of congenital infection and neuro-sensorial disease. The expanding target populations for HCMV antiviral treatment along with the limitations of the currently available HCMV DNA polymerase inhibitors underscore the need for new antiviral agents with alternative modes of action. The anti-malarial artemisinin derivative artesunate was shown to inhibit HCMV in vitro , yet has demonstrated limited antiviral efficacy in vivo , prompting our search for more potent anti-HCMV artemisinin derivatives...

The spatiotemporal control of HOX gene expression is dependent on positional identity and often correlated to their genomic location within each loci. Maintenance of HOX expression patterns is under complex transcriptional and epigenetic regulation, which is not well understood. Here we demonstrate that HOTTIP, a lincRNA transcribed from the 5' edge of the HOXA locus, physically associates with the CCCTC-binding factor (CTCF) that serves as an insulator by organizing HOXA cluster into disjoint domains, to cooperatively maintain the chromatin modifications of HOXA genes and thus coordinate the transcriptional activation of distal HOXA genes in human foreskin fibroblasts...

A 74-year-old man presented to our hospital with the swelling of penis in May 2016. Physical examination revealed a goose egg-sized lump at the tip of the penis under foreskin. After dorsal skin incision we confirmed the 7 cm tumor on the inner preputial skin and then resected the tumor with circumcision. Histopathological examination revealed sarcomatoid squamous cell carcinoma of the penis. Computed tomography (CT) revealed swelling of bilateral inguinal lymph nodes, and we performed partial penectomy with bilateral superficial inguinal lymph node dissection in July 2016...

BACKGROUND: Mesenchymal stromal cells (MSCs) become an attractive research topic because of their crucial roles in tissue repair and regenerative medicine. Foreskin is considered as a valuable tissue source containing immunotherapeutic MSCs (FSK-MSCs). RESULTS: In this work, we used aldehyde dehydrogenase activity (ALDH) assay (ALDEFLUOR™) to isolate and therefore characterize subsets of FSK-MSCs. According to their ALDH activity, we were able to distinguish and sort by fluorescence activated cell sorting (FACS) two subsets of FSK-MSCs (referred as ALDH+ and ALDH- )...

Sorghum [ Sorghum bicolor (L.) Moench] is a major cereal crop. Despite the wide cultivation of sorghum, its stalks are used as hay and silage. The plant has numerous bioactive compounds including cosmeceutical ingredients. Thus, we investigated the antimelanogenic and SSE that is prepared from the stalk of Sorghum bicolor L. (SSE) after ethanol (EtOH) extraction. Based on the antioxidant capacity, antityrosinase activity, and suppression of the protein expression levels of matrix metalloproteinase (MMP)-1, -2, and -3 in human neonatal foreskin HDF-N cells, a 50% EtOH extraction of SSEs showed antimelanogenic and antiwrinkle potential...

The obligate intracellular parasite Toxoplasma gondii controls its host cell from within the parasitophorous vacuole (PV) by using a number of diverse effector proteins, a subset of which require the aspartyl protease 5 enzyme (ASP5) and/or the recently discovered MYR1 protein to cross the PV membrane. To examine the impact these effectors have in the context of the entirety of the host response to Toxoplasma , we used RNA-Seq to analyze the transcriptome expression profiles of human foreskin fibroblasts infected with wild-type RH (RH-WT), RHΔ myr1 , and RHΔ asp5 tachyzoites...

Introduction: The megameatus intact prepuce (MIP) variant of hypospadias is a rare variant of hypospadias that is diagnosed either early at the time of circumcision or later as the foreskin is retracted. The true incidence of the anomaly is difficult to determine precisely as some patient never come to medical attention but is felt to under 5% of all cases of hypospadias. The purposes of this study are to review the embryology and clinical findings of MIP and then, in light of a personal experience, present a series of patients evaluated for MIP who were treated with a modification of the Mathieu technique...

Human papillomavirus (HPV) infection of the genital tract is common, however only about 10-15% of infections persist, and approximately 10-15% of these persistent infections result in cancer. Basal epidermal stem cells are the presumed target cells for HPV infection, providing a reservoir of latently infected cells that persist over time and initiate lesions. Yet, it is not known whether stem cell density has any influence on transformation of human keratinocytes by HPV. We explored the relationship between stem cell properties of normal human keratinocytes and their susceptibility to transformation by HPV16 DNA...
