Denervation of the extrinsic cardiac sympathetic nervous system is a method of altering the autonomic tone experienced by the heart and vasculature. It has been studied and employed as a therapy for cardiac disease for decades. Currently, there is a high level of interest in using cardiac denervation for treatment of arrhythmias. This review describes the anatomy and physiology of the cardiac autonomic nervous system followed by a discussion of the mechanistic studies which provide a basis for the therapeutic use of sympathetic denervation...

Thrombosis related diseases are among the main causes of death and incapacity in the world. Despite the existence of antithrombotic agents available for therapy, they still present adverse effects like hemorrhagic risks which justify the search for new options. Recently, pachydictyol A, isopachydictyol A, and dichotomanol, three diterpenes isolated from Brazilian marine brown alga Dictyota menstrualis were identified as potent antithrombotic molecules through inhibition of thrombin, a key enzyme of coagulation cascade and a platelet agonist...

Primary breast lymphoma is a rare disease and accounts for 0.5% of cases of breast cancer. Most primary breast lymphomas develop from B cells, and the involvement of T cells is rare. Anaplastic large cell lymphoma (ALCL) is a recently discovered T-cell lymphoma associated with breast implants. Only a few cases have been reported to date. It is believed that the incidence of ALCL is increasing because of the increasing number of breast implants. The clinical presentation is variable and can manifest as a palpable mass in the breast or armpit, breast pain, or capsular contracture...

BACKGROUND/AIMS: Severe dengue fever is a result of exacerbated immune responses and no specific treatments are available. We evaluated the antiviral and immunomodulatory effects of Norantea brasiliensis Choisy. METHODS: Human adherent monocytes infected in vitro with dengue virus (DENV)-2 were incubated with the crude ethanol extract from leaves (NB1) or 3 derived fractions: dichloromethane (NB3), ethyl acetate (NB5), and butanolic (NB6) partitions. The antiviral and immunomodulatory activities were determined by intracellular detection of DENV antigen within monocytes and by secreted NS1 viral protein and cytokines...

We have previously found that UV irradiation promotes RNA polymerase II (RNAPII) hyperphosphorylation and subsequent changes in alternative splicing (AS). We show now that UV-induced DNA damage is not only necessary but sufficient to trigger the AS response and that photolyase-mediated removal of the most abundant class of pyrimidine dimers (PDs) abrogates the global response to UV. We demonstrate that, in keratinocytes, RNAPII is the target, but not a sensor, of the signaling cascade initiated by PDs. The UV effect is enhanced by inhibition of gap-filling DNA synthesis, the last step in the nucleotide excision repair pathway (NER), and reduced by the absence of XPE, the main NER sensor of PDs...

There have been reports of the use of silicone oils in injectable form for cosmetic purposes since the 1940s. With the popularization of the use of this technique in the mid-60s, there have been a wide range of adverse effects reported. We report a 32-year-old woman, who had intramuscular injections of an unknown substance, which led to serious complications.

Platynosomiasis is a common feline hepatic disease caused by Platynosomum fastosum (Trematoda - Dicrocoelidae), which is also known as 'lizard poisoning'. Most reports of feline platynosomiasis show that this disease is sporadic and manifests with uncommon lesions; its pathogenicity is still not well understood. This study aimed to describe liver injuries and enzymatic changes associated with natural P. fastosum infection in 47 stray cats in an endemic area. Overall, 38.3% (18/47) of cats were parasitized, and 2,358 flukes (P...

Phytopathogenic fungi responsible for post-harvest diseases on fruit and vegetables cause important economic losses. We have previously reported that harmol (1-methyl-9H-pyrido[3,4-b]indol-7-ol) is active against the causal agents of green and gray molds Penicillium digitatum and Botrytis cinerea, respectively. Here, antifungal activity of harmol was characterized in terms of pH dependency and conidial targets; also photodynamic effects of UVA irradiation on the antimicrobial action were evaluated. Harmol was able to inhibit the growth of both post-harvest fungal disease agents only in acidic conditions (pH 5), when it was found in its protonated form...
