1.Simultaneous determination of timolol maleate in combination with some other anti-glaucoma drugs in rabbit aqueous humor by high performance liquid chromatography-tandem mass spectroscopy.
Hassib ST1, Elkady EF1, Sayed RM2. J Chromatogr B Analyt Technol Biomed Life Sci. 2016 Apr 7;1022:109-117. doi: 10.1016/j.jchromb.2016.04.012. [Epub ahead of print]
In this work, a sensitive, selective, accurate and precise LC-MS/MS method has been developed for the simultaneous determination of an anti-glaucoma ß-blocker, timolol maleate (TIM) with other co-administered anti-glaucoma drugs of different classes, namely; dorzolamide hydrochloride (DOR), brinzolamide (BRZ) and brimonidine tartrate (BRM) in rabbit aqueous humor (AH) using eslicarbazepine as an internal standard (IS). Liquid-liquid extraction was used for the purification and pre-concentration of analytes from rabbit AH matrix. The chromatographic separation was achieved using a mobile phase consisting of 10mM ammonium formate pH=7: methanol: acetonitrile (5: 50: 45, v/v/v) in isocratic mode of elution at a flow rate of 0.8mL/min on an INERTSIL® C18 ODS-3 column (150mm×4.6mm, 3.5μm). The method was operated using electrospray ionization source in the positive ionization mode prior to detection by multiple reaction monitoring (MRM) at the following transitions: m/z 317.
2.A simple route to develop transparent doxorubicin-loaded nanodiamonds/cellulose nanocomposite membranes as potential wound dressings.

The objective of this study is to develop transparent porous nanodiamonds/cellulose nanocomposite membranes with controlled release of doxorubicin for potential applications as wound dressings, which were fabricated by tape casting method from dispersing carboxylated nanodiamonds and dissolving cellulose homogeneously in 7wt% NaOH/12wt% urea aqueous solution. By adjusting the carboxylated nanodiamonds content, various nanocomposite membranes were obtained. The structure and properties of these membranes have been investigated by light transmittance measurements, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), tensile tests, water loss analyses, etc. The drug loading and release was investigated using doxorubicin hydrochloride as a model drug. In vitro cytotoxicity assay of the membranes was also studied. This work presented a proof-of-concept utility of these membranes for loading and release of bioactive compounds to be employed as a candidate for wound dressing.
3.Mucosal acidification increases hydrogen sulfide release through up-regulating gene and protein expressions of cystathionine gamma-lyase in the rat gastric mucosa.
Mard SA1, Veisi A2, Ahangarpour A2, Gharib-Naseri MK2. Iran J Basic Med Sci. 2016 Feb;19(2):172-7.
OBJECTIVES: This study was performed to investigate the effects of mucosal acidification on mRNA expression and protein synthesis of cystathionine gamma lyase (CSE), cystathionine beta synthase (CBS), and mucosal release of H2S in gastric mucosa in rats.
4.Prolonged Drainage and Intrapericardial Bleomycin Administration for Cardiac Tamponade Secondary to Cancer-Related Pericardial Effusion.
Numico G1, Cristofano A, Occelli M, Sicuro M, Mozzicafreddo A, Fea E, Colantonio I, Merlano M, Piovano P, Silvestris N. Medicine (Baltimore). 2016 Apr;95(15):e3273. doi: 10.1097/MD.0000000000003273.
Malignant pericardial effusion (MPE) is a serious complication of several cancers. The most commonly involved solid tumors are lung and breast cancer. MPE can give rise to the clinical picture of cardiac tamponade, a life threatening condition that needs immediate drainage. While simple pericardiocentesis allows resolution of the symptoms, MPE frequently relapses unless further procedures are performed. Prolonged drainage, talcage with antineoplastic agents, or surgical creation of a pleuro-pericardial window are the most commonly suggested ones. They all result in MPE resolution and high rates of long-term control. Patients suitable for further systemic treatments can have a good prognosis irrespective of the pericardial site of disease. We prospectively enrolled patients with cardiac tamponade treated with prolonged drainage associated with Bleomycin administration.Twenty-two consecutive patients with MPE and associated signs of hemodynamical compromise underwent prolonged drainage and subsequent Bleomycin administration.
