P Mendes-Bastos, R Macedo, R Duarte
Hidradenitis suppurativa (HS) is a chronic, recurrent and debilitating skin disease of the hair follicle that is accompanied by systemic inflammation. Treating HS is challenging, and therapeutic tools as diverse as topical and systemic antibiotics, biologics, intralesional steroids, surgical procedures or light and laser therapies are frequently needed. The combination of oral clindamycin and rifampicin (R+C) has been suggested as a possible treatment regimen (level of evidence III, strength of recommendation C)...

Evolutionary studies of mammalian teeth have generally concentrated on the adaptive and functional significance of dental features, whereas the role of development on phenotypic generation and as a source of variation has received comparatively little attention. The present study combines an evolutionary biological framework with state-of-the-art imaging techniques to examine the developmental basis of variation of accessory cusps. Scholars have long used the position and relatedness of cusps to other crown structures as a criterion for differentiating between developmentally homologous and homoplastic features, which can be evaluated with greater accuracy at the enamel-dentine junction (EDJ)...

BACKGROUND: The TNM system is an established tool for classification of solid tumors by means of tumor size and extent, the involvement of local lymph nodes, and the presence of distant metastases. The classification was established in order to visualize prognostic implications and to allow establishment of systematic therapeutic algorithms. Since the beginning of 2017 a revised version of the classification has applied. Particularly the classification of otorhinolaryngologic tumors has been thoroughly revised in the 8th edition, partly on the basis of new prognostically relevant parameters, such as infection with oncogenic human papillomavirus (HPV) subtypes...

PURPOSE: Maxillofacial deformities are always psychologically and physically distressing to the patients and is also challenging to the treating surgeons. The term Micrognathia means a "small jaw". True micrognathia, where the maxilla or the mandibular skeleton does not grow to the full size can be congenital or acquired. Distraction osteogenesis also called as callus distraction or callostasis or osteodistraction or distraction histogenesis is a biological process of regenerating newly formed bone and adjacent soft tissue by a gradual and controlled traction of surgically separated bone segments...

Ketoprofen L-lysine salt (KLS), is widely used due to its analgesic efficacy and tolerability, and L-lysine was reported to increase the solubility and the gastric tolerance of ketoprofen. In a recent report, L-lysine salification has been shown to exert a gastroprotective effect due to its specific ability to counteract the NSAIDs-induced oxidative stress and up-regulate gastroprotective proteins. In order to derive further insights into the safety and efficacy profile of KLS, in this study we additionally compared the effect of lysine and arginine, another amino acid counterion commonly used for NSAIDs salification, in control and in ethanol challenged human gastric mucosa model...

Vanadium compounds are promising anti-diabetic agents. However, reducing the metal toxicity while keeping/improving the hypoglycemic effect is still a big challenge towards the success of anti-diabetic vanadium drugs. To improve the therapeutic potency using the anti-oxidative strategy, we synthesized new N,N-dimethylphenylenediamine (DMPD)-derivatized nitrilotriacetic acid vanadyl complexes ([VO(dmada)]). The in vitro biological evaluations revealed that the DMPD-derivatized complexes showed improved antioxidant capacity and lowered cytotoxicity on HK-2 cells than bis(maltolato)oxidovanadium (IV) (BMOV)...

Because of the common shared risk factors of smoking and heavy alcohol consumption, literature involving oropharyngeal squamous cell carcinoma (OPSCC) is often combined with oral squamous cell carcinoma. Human papilloma virus is now confirmed to be a major risk factor of OPSCC with its distinct epidemiology and favorable treatment outcome. The impact of adjuvant chemoradiation in the setting of positive surgical margins remains unclear but is likely influenced by tumor biology. This article reviews the tumor biology of OPSCC and summarizes recent findings on outcomes following surgical treatment of OPSCC...

Crohn's disease is a heterogeneous, inflammatory condition that can affect any location of the gastrointestinal tract. Proximal gastrointestinal involvement occurs in 0.5-16% of patients, and it is usually diagnosed after recognition of intestinal disease. Symptoms are often mild and non-specific, however upper gastrointestinal disease predicts a more severe Crohn's phenotype with a greater frequency of complications such as obstruction and perforation. Gastroscopy and biopsy is the most sensitive diagnostic investigation...

16-hydroxycleroda-3, 13-dine-15, 16-olide (HCD) isolated from Polyalthia longifolia possesses numerous biological activities. Previous studies have reported that HCD can block phosphorylation activity of cancer cells to inhibit tumor cell growth, but the anti-tumor activity in oral squamous cell carcinoma is unrevealed. This study investigates the inhibiting effect of HCD on human OSCC cell growth; thereby, developing a new oral cancer drug. In in vitro cultured human OSCC cells (OECM1 and SAS) were employed to test the inhibitory growth of HCD via cell cytotoxic effect using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, Western blotting, and further determining of the inhibitory efficacy of tumor growth by a xenograft tumor on BALB/c male nude mice (in vivo test)...

BACKGROUND: Tenofovir disoproxil fumarate (TDF) is key component of pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART) for HIV, but existing tools to monitor drug adherence are often inaccurate. Detection of tenofovir (TFV) in accessible biological samples, such as fingerprick blood, urine or oral fluid samples could be a novel objective measure of recent TDF adherence. To measure TFV concentrations associated with different levels of TDF adherence, we designed a randomized clinical trial to assess the blood, urine and oral fluid concentrations of TFV in adults with perfect, moderate and low drug adherence...

This review traces the journey of nanosomes from administration until elimination, and discusses various biological barriers. The nanosomes are imported into the body through different routes and are localized into specified organ, cell, subcellular locations or organelle compartment. The nanosomes delivery to a specific destination depends on the surface chemistry, size, shape and the presence of specific ligands. Endocytosis/exocytosis cycles are involved in the import and export of the nanosomes. The mononuclear phagocytic system and ATP-binding cassette are universal checkpoints for nanosomes trafficking...

Light subunit of mushroom tyrosinase (LSMT) is a protein of unknown function from mushroom Agaricus bisporus that has been demonstrated to permeate through rat intestine ex vivo. Thus, it can be absorbed in the intestine, thereby holding a promise as a drug carrier for oral administration, similar to HA-33 protein from botulinum, one of the closest structural homologs of LSMT. However, the safety of LSMT should be ensured prior to its use. Here, we described biological response of LSMT upon weekly intraperitoneal administration of 50 μg/day to the Balb/c mice for 12 weeks...
