Elbasvir/Grazoprevir combination therapy in a B-NHL patient with HCV genotype 1 infection.

Patients with indolent non-Hodgkin lymphomas (NHL) may often be followed up only with observation, reserving chemotherapy in case of spread. Patients with chronic HCV infection and B cell NHL frequently undergo regression of lymphoproliferative disease once HCV infection is eradicated by treatment. Interferon (IFN)-based therapy has been the treatment of choice for years, remaining unclear whether it is effective in B cell NHL directly or through HCV eradication, since IFN is effective in both HCV infection and B cell NHL.

Differential Diagnosis: Retroperitoneal Fibrosis and Oncological Diseases.

Retroperitoneal fibrosis is a connective disease of the auto-inflammatory/auto-immune type of the retroperitoneum with unknown etiology and pathological mechanism. The manifestations of the pathology can be local or systemic. Amongst the local symptoms, the dull and constant pain in the hips, back or abdomen is the most frequent.

Cancer- and Non-cancer Related Chronic Pain: From the Physiopathological Basics to Management.

The prevalence of chronic pain is between 33% to 64% and is due to cancer pain, but it has also been observed in non-cancer patients. Chronic pain is associated with lower quality of life and higher psychological distress and depressive/anxiety disorders in patients without a history of disorder. In this study we evaluated in clinical practice the effectiveness of the intrathecal pump in 140 patients who underwent pain therapy at our Center.

Synthesis and evaluation of diverse analogs of amygdalin as potential peptidomimetics of peptide T.

Peptide T (ASTTTNYT) is a promising molecule to prevent the neuropsychometric symptoms of patients suffering AIDS and for the treatment of psoriasis. In order to fully prove its therapeutic benefits, efforts were put forward to design peptidomimetics of the peptide. In this direction, in a recent computational study the natural product amygdalin was identified as a prospective peptidomimetic of the peptide and later proved to exhibit a similar chemotactic profile to the peptide.

Productive trapping of NAD-type radicals. Non-biomimetic reduction of pyridinium salts.

One-electron reduction of pyridinium salts (NAD+ analogues) generates dihydropyridyl radicals which may then be engaged in radical addition processes to regioselectively form gamma-substituted dihydropyridines.
