Cutaneous lymphomas are classified according to their cellular origin into T-cell lymphoma and B-cell lymphoma. The annual incidence rate is 0.3 per 100,000 population. We report a case of a 56-year-old male patient who presented with a two-month history of nodules of varying sizes, some ulcerated, on the face, abdomen, and upper limbs. Histopathological examination and immunohistochemical study confirmed the diagnosis of primary cutaneous centrofollicular lymphoma. Studies have shown an increased incidence of non-Hodgkin lymphomas in the last decade...

OBJECTIVE: The new epidemic of Zika virus infection raises grave concerns, especially with the increasingly-recognized link between emerging cases of microcephaly and this infectious disease. Besides small cranial dimensions, there are striking morphologic anomalies in the fetal brain. Key anomalies include cortical developmental malformations and a peculiar distribution of pathologic calcifications. These potentially indicate a new pattern of congenital central nervous system infection...

MicroRNAs (miRNAs) are noncoding RNAs of around 20-25 nucleotides in length with highly conserved characteristics. They moderate posttranscriptional silencing by precisely combining with 3' untranslated regions (UTRs) of target mRNAs at a complementary site. miR503, an associate of the "canonical" miRNA16 family, is expressed in numerous types of tumors such as breast cancer, prostate cancer, lung cancer, colorectal cancer, hepatocellular carcinoma, glioblastoma and several others. There is convincing evidence to show that miR503 functions as a tumor suppressor gene through its effects on target genes that regulate cell proliferation, migration, and invasion in tumor cells...

The development of gold catalysis has allowed significant levels of activity and complexity in organic synthesis. Recently, the use of very active small gold subnanoclusters (Au n , n < 10) has been reported. The stabilization of such nanocatalysts to prevent self-aggregation represents a true challenge that has been partially remediated, for instance, by their immobilization in polymer matrices. Here, we describe the transient stabilization of very small gold subnanoclusters (Au n , n < 5) by alkyl chains or aromatic groups appended to the reactive π bond of simple alkynes...

The early establishment of the diagnosis of a syndesmotic injury is essential for treatment selection. However, such injuries may not be apparent radiographically. Previous studies have attempted to describe correlations between medial malleolar fracture geometry and syndesmotic disruption. The main objective of this study was to create predictive models for assessing syndesmotic injuries based on an originally described angle, i.e., the medial crural-focal angle (MCFA). This study included 138 ankle fractures involving the medial malleolus...

BACKGROUND AND AIMS: Left ventricular hypertrophy (LVH) in hypertension is associated with a greater risk of sustained supraventricular/atrial arrhythmias. Dronedarone is an antiarrhythmic agent that was recently approved for the treatment of atrial fibrillation. However, its effect on early regression of LVH has not been reported. We tested the hypothesis that short-term administration of dronedarone induces early regression of LVH in spontaneously hypertensive rats (SHRs). METHODS: Ten-month-old male SHRs were randomly assigned to an intervention group (SHR-D), where animals received dronedarone treatment (100 mg/kg) for a period of 14 days, or to a control group (SHR) where rats were given vehicle...

The lymnaeids are important in the epidemiology of Fasciola hepatica, a neglected and endemic zoonosis. The interaction between the internal defense system of Pseudosuccinea columella and F. hepatica has been little studied. In the present study the effect of infection by F. hepatica on P. columella circulating haemocytes was investigated. Changes in the average number of total circulating haemocytes have been observed at 30 minutes post-infection and 1, 7, 10, 14, 21, 28 and 50 days post-infection (dpi). Miracidia were observed head-foot and mantle at 30 minutes post-infection...

Background: Curative surgery is performed for a foot with ulcers and loss of protective sensation to heal the wound and prevent amputation. Evidence supports that patients with diabetes have decreased concentrations of growth factors in their tissues, notably epidermal growth factor (EGF). Injecting EGF deep into the bottom of the wound and its contours encourages a more effective response in terms of granulation tissue growth and wound closure. Objective: To assess the effectiveness and safety of curative metatarsal bone surgery combined with intralesional administration of human recombitant EGF in neuropathic diabetic forefoot ulceration...

PRIMARY OBJECTIVE: Repeated traumatic brain injuries (rmTBI) are frequently associated with debilitating neuropsychiatric conditions such as cognitive impairment, mood disorders, and post-traumatic stress disorder. We tested the hypothesis that repeated mild traumatic brain injury impairs spatial memory and enhances anxiety-like behaviour. RESEARCH DESIGN: We used a between groups design using single (smTBI) or repeated (rmTBI) controlled cranial closed skull impacts to mice, compared to a control group...

There is an increasing body of evidence about the effect that early nutrition and lifestyle could have on the programming of later health and disease. Infant formula must cover all the nutritional needs to promote adequate infant growth and development. Currently, important research efforts have been made to supplement infant formulae with new bioactive ingredients with health benefits for the infant. The milk fat globule membrane is one of the new ingredients, which provides phospholipids and gangliosides, as well as bioactive proteins...

Polyunsaturated fatty acids and antioxidants are important mediators in the central nervous system. Lipid derivatives may control the production of proinflammatory agents and regulate NF-κB activity, microglial activation, and fatty acid oxidation; on the other hand, antioxidants, such as glutathione and ascorbate, have been shown to signal through transmitter receptors and protect against acute and chronic oxidative stress, modulating the activity of different signaling pathways. Several authors have investigated the role of these nutrients in the brains of the young and the aged in degenerative diseases such as Alzheimer's and Parkinson's, and during brain aging due to adiposity- and physical inactivity-mediated metabolic disturbances, chronic inflammation, and oxidative stress...

The effect of above-normal body mass index (BMI) on health outcomes is controversial because it is difficult to distinguish from the effect due to BMI-associated cardiovascular risk factors. The objective was to analyze the impact on 10-year incidence of cardiovascular disease, cancer deaths and overall mortality of the interaction between cardiovascular risk factors and BMI. We conducted a pooled analysis of individual data from 12 Spanish population cohorts with 10-year follow-up. Participants had no previous history of cardiovascular diseases and were 35-79years old at basal examination...

There is currently considerable discussion about the relative influences of evolutionary and cultural factors in the development of early numerical skills. In particular, there has been substantial debate and study of the relationship between approximate, nonverbal (approximate magnitude system [AMS]) and exact, symbolic (symbolic number system [SNS]) representations of number. Here we examined several hypotheses concerning whether, in the earliest stages of formal education, AMS abilities predict growth in SNS abilities, or the other way around...

BACKGROUND: Myofascial trigger points are dysfunctional structures present in skeletal muscles and are related to sensory, motor, and autonomic changes. Despite scientific advances in recent decades in the measurement of musculoskeletal pain, evaluation of this clinical phenomenon is supported with instruments that, although valid and reliable, have a considerable degree of subjectivity. OBJECTIVE: To correlate electrical impedance of the upper limbs and torso with pain intensity, functional capacity, catastrophizing, pressure pain threshold, and skin temperature on myofascial trigger points in the upper trapezius muscle of patients with neck pain...

This paper explores the association between job strain and adiposity, using two statistical analysis approaches and considering the role of gender. The research evaluated 11,960 active baseline participants (2008-2010) in the ELSA-Brasil study. Job strain was evaluated through a demand-control questionnaire, while body mass index (BMI) and waist circumference (WC) were evaluated in continuous form. The associations were estimated using gamma regression models with an identity link function. Quantile regression models were also estimated from the final set of co-variables established by gamma regression...
