Diagnosis and treatment planning are important for successful endodontic treatment. We report a 24-year old male who presented to the Government Dental College in Kozhikode, Kerala, India, in 2015 with pain in his right upper canine. A digital periapical radiograph indicated the presence of a supernumerary tooth superimposing the root of the canine. However, cone-beam computed tomography (CBCT) confirmed that the supernumerary tooth was an illusion and that the canine root had a sharp invagination involving the labial and pulpal dentin surfaces, with evidence of periapical bone destruction...

Alloyed CuInZn x S2+x (ZCIS) quantum dots (QDs) were successfully associated to ZnO nanoparticles by a thermal treatment at 400 °C for 15 min. The ZnO/ZCIS composite was characterized by TEM, SEM, XRD, XPS and UV-vis absorption spectroscopy. ZCIS QDs, with an average diameter of ≈4.5 nm, were found to be homogeneously distributed at the surface of ZnO nanoparticles. ZCIS-sensitized ZnO nanoparticles exhibit a high photocatalytic activity under simulated solar light irradiation for the degradation of Orange II dye (>95% degradation after 180 min of irradiation at an intensity of 5 mW/cm(2))...

Age-related health decline has been attributed to the accumulation of senescent cells recognized in vivo by p16(Ink4a) expression. The pharmacological elimination of p16(Ink4a)-positive cells from the tissues of mice was shown to extend a healthy lifespan. Here, we describe a population of mesenchymal cells isolated from mice that are highly p16(INK4a)-positive are proficient in proliferation but lack other properties of cellular senescence. These data, along with earlier reports on p16(Ink4a)-positive macrophages, indicate that p16(Ink4a)-positive and senescent cell populations only partially intersect, therefore, extending the list of potential cellular targets for anti- aging therapies...

Many properties of aqueous cations depend on their coordination state. However, the lack of long-range order and the dynamic character of aqueous solutions make it difficult to obtain information beyond average coordination parameters. A thorough understanding of the molecular-scale environment of aqueous cations usually requires a combination of experimental and theoretical approaches. In the case of Zn(2+), significant discrepancies occur among theoretical investigations based on first-principles molecular dynamics (FPMD) or free-energy calculations, although experimental data consistently point to a dominant hexaaquo-zinc complex (Zn[H2O]6)(2+) in pure water...

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...

Tissue integrity requires constant maintenance of a quiescent, yet responsive, population of stem cells. In the skin, hair follicle stem cells (HFSCs) that reside within the bulge maintain tissue homeostasis in response to activating cues that occur with each new hair cycle or upon injury. We found that PTEN, a major regulator of the PI3K-AKT pathway, controlled HFSC number and size in the bulge and maintained genomically stable pluripotent cells. This regulatory function is central for HFSC quiescence, where PTEN-deficiency phenotype is in part regulated by BMAL1...

It is important to assess outcomes for medical interventions in order to focus scarce resources on outcomes with a known positive benefit. An open, observational study was performed to assess the clinical outcomes of 600 male patients with a genital skin problem attending a specialist secondary care dermatology facility. Patients were mainly referred by general practitioners and genitourinary medicine physicians. Outcome was measured at 3 and 6 months, and was determined by clinical examination and assessment of patient symptoms...

Penile inflammatory skin conditions such as balanitis and posthitis are common, especially in uncircumcised males, and feature prominently in medical consultations. We conducted a systematic review of the medical literature on PubMed, EMBASE, and Cohrane databases using keywords "balanitis," "posthitis," "balanoposthitis," "lichen sclerosus," "penile inflammation," and "inflammation penis," along with "circumcision," "circumcised," and "uncircumcised." Balanitis is the most common inflammatory disease of the penis...

The uptake and transport of sulfate in bacteria is mediated by an ATP-binding cassette transporter (ABC transporter) encoded by sbpcysUWA genes, whose importance has been widely demonstrated due to their relevance in cysteine synthesis and bacterial growth. In Xanthomonas citri, the causative agent of canker disease, the expression of components from this ABC transporter and others related to uptake of organic sulfur sources has been shown during in vitro growth cultures. In this work, based on gene reporter and proteomics analyses, we showed the activation of the promoter that controls the sbpcysUWA operon in vitro and in vivo and the expression of sulfate-binding protein (Sbp), a periplasmic-binding protein, indicating that this protein plays an important function during growth and that the transport system is active during Citrus sinensis infection...

A "buried penis" causes functional problems and embarrassment. In the past, this complex condition was only seen in extremely overweight patients or as a result of severe inflammations in this region. More recently, this problem has also been observed in patients with massive weight loss following bariatric surgery. In these patients there is an abundance of extremely flaccid skin in the suprapubic region, which covers the penis and causes it to "disappear". This leads to balanitis and, in turn, further retraction of the penis...

Biodegradable oligolactide derivatives based on α-, β- and γ-cyclodextrins (CDs) were synthesized by a green procedure in which CDs play the role of both the initiator and the catalyst. The synthetic procedure in which CDs and L-lactide (L-LA) are reacting in bulk at relatively high temperature of 110 °C was investigated considering the structural composition of the products. The obtained products were thoroughly characterized via mass spectrometry methods with soft ionization like matrix-assisted laser desorption ionization (MALDI) and electrospray ionization (ESI)...

In Escherichia coli, the ATP-Binding Cassette transporter for phosphate is encoded by the pstSCAB operon. PstS is the periplasmic component responsible for affinity and specificity of the system and has also been related to a regulatory role and chemotaxis during depletion of phosphate. Xanthomonas citri has two phosphate-binding proteins: PstS and PhoX, which are differentially expressed under phosphate limitation. In this work, we focused on PhoX characterization and comparison with PstS. The PhoX three-dimensional structure was solved in a closed conformation with a phosphate engulfed in the binding site pocket between two domains...

The Rapid Bioconversion with Integrated recycling Technology (RaBIT) process uses enzyme and yeast recycling to improve cellulosic ethanol production economics. The previous versions of the RaBIT process exhibited decreased xylose consumption using cell recycle for a variety of different micro-organisms. Process changes were tested in an attempt to eliminate the xylose consumption decrease. Three different RaBIT process changes were evaluated in this work including (1) shortening the fermentation time, (2) fed-batch hydrolysate addition, and (3) selective cell recycling using a settling method...

BACKGROUND: The defects over the leg, foot and ankle are best covered with a thin pliable flap. The use of muscle flap for the reconstruction of these defects leaves a grafted, aesthetically inferior result. The medial sural artery perforator (MSAP) free flap gives a thin pliable tissue for the reconstruction with better aesthesis. METHODS: The study design was retrospective case analysis over a period of 2 years. All the patients who underwent flap for leg, foot and ankle defect reconstruction in the form of MSAP free flap were included in the study...

Zoon's balanitis is an asymptomatic lesion that requires histopathological examination of involved tissue for confirmation of diagnosis. Till today, circumcision is considered as the treatment of choice as topical medical therapy is insufficient to cure the disease and also there was a risk of recurrence after discontinuation of therapy. Herein, we have treated the Zoon's balanitis with 0.1% topical tacrolimus with complete resolution of the lesion in 6 weeks. Hence, we think topical tacrolimus therapy should be considered as an alternative to circumcision in the treatment of Zoon's balanitis...
