INTRODUCTION: The common tool for diagnosing prostate cancer is prostate-specific antigen (PSA), but the high sensitivity and low specificity of PSA testing are the problems in clinical practice. There are no proper guidelines to investigate the suspected prostate cancer in the Cayman Islands. We correlated PSA levels with the incidence of prostate cancers by tissue diagnosis and proposed logical protocol for prostate screening by using PSA test in this small population. MATERIALS AND METHODS: A total of 165 Afro Caribbean individuals who had prostate biopsy done after the investigations for PSA levels from year 2005 to 2015 were studied retrospectively...

Mari Sild, Edward S Ruthazer, Linda Booij
Despite intense ongoing research efforts, the etiology of psychiatric disorders remains incompletely understood. Among biological factors playing a role in Major Depressive Disorder (MDD) and Anxiety Disorders (ANX), emerging evidence points to the relevance of different types of glia cells and efficient neuron-glia interactions. Here, we review recent findings highlighting the involvement of central nervous system (CNS) glia in MDD and ANX etiology and treatment response. Additionally, several relatively underexplored topics will be discussed: 1) glial response to non-pharmacological therapies, 2) impact of early life adversity on glia, 3) influence of lifestyle factors on glia in the context of MDD and ANX, and 4) monitoring glial functions in patients...

INTRODUCTION: Oral cancer is a serious public health issue. Apart from its high rate of prevalence, incidence and mortality, it can often result in more complex and expensive treatment when diagnosed late. Potentially malignant disorders (PMDs) can precede oral cancer, and are usually treated by surgical excision. However, in many cases patients are elderly and multiple interventions may be required. Photodynamic therapy (PDT) is a simple alternative, which has been successfully used in the treatment of oral PMDs...

Lactobacillus wasatchensis, an obligate heterofermentative nonstarter lactic acid bacteria (NSLAB) implicated in causing gas defects in aged cheeses, was originally isolated from an aged Cheddar produced in Logan, Utah. To determine the geographical distribution of this organism, we isolated slow-growing NSLAB from cheeses collected in different regions of the United States, Australia, New Zealand, and Ireland. Seven of the cheeses showed significant gas defects and 12 did not. Nonstarter lactic acid bacteria were isolated from these cheeses on de Man, Rogosa, and Sharpe medium supplemented with ribose, a preferred substrate for Lb...

PURPOSE: It was hypothesized that tear protein biomarkers could predict the effects of topical steroid treatment and desiccating stress in patients with dry eye disease (DED). To test this concept, a randomized, double-masked, controlled clinical trial with 41 patients was conducted. METHODS: The patients were treated topically with either 0.1% fluorometholone (FML) or polyvinyl alcohol (PA). Tear samples were collected using 1 μl glass capillaries at recruitment into the study and after a 3-week treatment period, both before and after 2 h exposure to desiccating stress, in a controlled environment chamber...

The bioadhesive polymeric films as topical drug delivery systems are interesting alternatives to improve the pharmacotherapy and patient compliances. New derivate biomaterials based on weisocyanate- dendronized PVP- crosslinked chitosan and loaded with ciprofloxacin (CIP), as model drug, were used to prepare bioadhesive films. Relevant in vitro/in vivo attributes to define main physicochemical and biopharmaceutical characteristics for topical wound-healing applications were evaluated. A high proportion of CIP, uniformly dispersed along throughout the film, was loaded...

Sample preparation still remains a great challenge in the analytical workflow representing the most time-consuming and laborious step in analytical procedures. Ideally, sample pre-treatment procedures must be more selective, cheap, quick and environmental friendly. Molecular imprinting technology is a powerful tool in the development of highly selective sample preparation methodologies enabling to preconcentrate the analytes from a complex food matrix. Actually, the design and development of molecularly imprinted polymers-based functional materials that merge an enhancement of selectivity with a controllable and switchable mode of action by means of specific stimulus constitutes a hot research topic in the field of food analysis...

BACKGROUND: Methotrexate (MTX) is an antimetabolite drug used in the treatment of cancers and autoimmune diseases and frequently in dermatology for cutaneous and/or arthritic psoriasis. Toxicities due to MTX overdosage are mainly cutaneous, hepatic and hematologic. Herein, we report a case of MTX overdosage presenting as an erosive and an inflammatory flare of preexisting psoriatic plaques and with new palmar lesions. PATIENTS AND METHODS: A 51-year-old male with a 6-year history of plaque psoriasis resistant to topical corticosteroids was started for the first time on MTX 20mg weekly...

The controlled drug release from hydrogel-based drug delivery systems is a topic of large interest for research in pharmacology. The mathematical modeling of the behavior of these systems is a tool of emerging relevance, since the simulations can be of use in the design of novel systems, in particular for complex shaped tablets. In this work a model, previously developed, was applied to complex-shaped oral drug delivery systems based on hydrogels (Dome Matrix®). Furthermore, the model was successfully adopted in the description of drug release from partially accessible Dome Matrix® systems (systems with some surfaces coated)...

Prophylactic mastectomy is an effective strategy to reduce the risk of breast cancer for women carrying a BRCA1/2 germline mutation. This decision is complex and may raise various concerns. Women considering this surgery have reported their desire to discuss the implications of this procedure with women who have undergone prophylactic mastectomy. We conducted a qualitative study to describe the topics covered during a telephone-based peer support intervention between women considering prophylactic mastectomy (recipients) and women who had undergone this surgery (peers), and to explore their perspectives regarding the intervention...

Some health research suggests that religious and spiritual variables positively predict health-screening behaviours. However, much of the literature on this topic has utilized exclusively religious samples, or has sampled from populations without uniform access to health care. Either of these issues may have artificially inflated the relationship between religion/spirituality and health-screening behaviours. The current study used data from the 2012 Canadian Community Health Survey to examine a general sample of women from New Brunswick and Manitoba (N > 1200)...

Symbiotic nitrogen fixation (SNF) is an energetically expensive process performed by bacteria during endosymbiotic relationships with plants. The bacteria require the plant to provide a carbon source for generation of reductant to power SNF. While C4-dicarboxylates (succinate, fumarate, malate) appear to be the primary, if not sole, carbon source provided to the bacteria, the contribution of each C4-dicarboxylate is not known. We address this issue using a genetic and systems-level analyses. Expression of a malate specific transporter (MaeP) in Sinorhizobium meliloti Rm1021 dct mutants unable to transport C4-dicarboxylates resulted in malate import rates up to 30% that of wild type...

Adult cardiomyocytes (CMs) possess a highly restricted intrinsic regenerative potential -a major barrier to the effective treatment of a range of chronic degenerative cardiac disorders characterised by cellular loss and/or irreversible dysfunction and which underlies the majority of deaths in developed countries. Both stem cell programming and direct cell reprogramming hold promise as novel, potentially curative approaches to address this therapeutic challenge. The advent of induced pluripotent stem cells (iPSCs) has introduced a second pluripotent stem cell source besides embryonic stem cells (ESCs), enabling even autologous cardiomyocyte production...

Primycin-sulphate is a highly effective compound against Gram (G) positive bacteria. It has a potentially synergistic effect with vancomycin and statins which makes primycin-sulphate a potentially very effective preparation. Primycin-sulphate is currently used exclusively in topical preparations such as in in vitro animal hepatocyte and neuromuscular junction studies (in mice, rats, snakes, frogs) as well as in in vitro human red blood cell experiments. During these studies, the use of primycin-sulphate resulted in reduced cellular membrane integrity and modified ion channel activity...
