Diamond McGehee, Mohammad Alimohammadi, Maria V Khodakovskaya
Carbon-based nanomaterials (CBNs) were previously described as regulators of plant cell division. Here, we demonstrated the ability of multi-walled carbon nanotubes (MWCNT) and graphene to enhance biomass production in callus culture of the medicinal plant Catharanthus roseus cultivated in dark conditions. Furthermore, both tested CBNs were able to stimulate biosynthesis of total produced alkaloids in CBN-exposed callus culture of Catharanthus. In one case, total alkaloids in CBN-exposed Catharanthus were double that of unexposed Catharanthus...

HIV-1 infects CD4+ T lymphocytes with a 'helper' function and myeloid cells, mostly tissue-resident macrophages. While infection of CD4 T lymphocytes in the absence of combination antiretroviral therapy (cART) leads to their depletion and to a profound immunodeficiency, macrophages are resistant to virus-induced cytopathicity and are a source of infectious virus, particularly in the central nervous system (CNS). Infected macrophages are characterized by accumulating newly formed viral particles (virions) in subcellular vacuoles defined as 'virus-containing compartments (VCC)', derived from invaginations of the plasma membrane, that are poorly accessible to antiretroviral agents and anti-HIV antibodies...

#4
REVIEW
Dariusz C Górecki
Mutations in the dystrophin and sarcoglycans genes result in muscular dystrophies causing severe disability and premature death and where no effective treatment is available. New therapeutic approaches targeting secondary disease mechanisms have a strong translational potential. Dystrophic muscle damage triggers release of ATP whilst loss of ecto-ATPase activity of sarcoglycan further elevates extracellular ATP (eATP) levels. Such a high eATP activates P2X7 purinoceptors on immune cells; these contribute to chronic inflammatory and immune responses that exacerbate the dystrophic pathology...

Donghu Zhang, Tian Yang, Jianyang Lin
As a novel non-purine xanthine oxidase inhibitor, WSJ-557 is a potential drug for gout. To determine the WSJ-557 concentration in plasma and various tissues of rats, a fast and sensitive method was first established by the ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) in this paper. The liquid-liquid extraction of ethyl acetate was adopted for the sample preparation, and carbamazepine was taken as the internal standard. In the process of chromatographic separation, MRM transitions for WSJ-557 and carbamazepine (internal standard, IS) were m/z 316...

The assessment of polymorphism is a problematical issue for regulatory agencies, because variations among crystalline forms of active pharmaceutical ingredient (API) can lead to changes in the efficacy and safety of formulated product. Such conversions are very hard to be detected, thus, the development of techniques for the identification, characterization and quantification of polymorphs results essential in all stages of the manufacturing process. The presence of excipients in formulated products may change the crystal stability of an API, by catalyzing a polymorphic transformation or stabilizing the less stable form...

Brucea javanica is an important Chinese folk medicine traditionally used for the treatment of dysentery (also known as inflammatory bowel diseases). Brucea javanica oil emulsion (BJOE), the most common preparation of Brucea javanica, has a variety of pharmacological activities. In this follow-up investigation, we endeavored to illuminate the potential benefit of BJOE on 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced Crohn's disease (CD) in rats and decipher the mechanism of action. The result illustrated that BJOE treatment significantly reduced the body weight loss, disease activity index and macroscopic scores, ameliorated shortening of colon length, arrested colonic histopathological deteriorations, lowered the histological scores in parallel to the model group...

Background Acute rejection (AR) is one of the most frequent complications after kidney transplantation (KT). Scientific evidence reports that some single-nucleotide polymorphisms (SNPs) located in genes involved in the immune response and in the pharmacokinetics and pharmacodynamics of immunosuppressive drugs are associated with rejection in renal transplant patients. The aim of this study was to evaluate some SNPs located in six genes: interleukin-10 (IL-10), tumor necrosis factor (TNF), adenosine triphosphate-binding cassette sub-family B member 1 (ABCB1), uridine diphosphate glucuronosyltransferase family 1 member A9 (UGT1A9), inosine monophosphate dehydrogenase 1 (IMPDH1) and IMPDH2...

Global malaria cases have not been significantly reduced over the last three years although more than USD 3 billion was invested in malaria control and elimination. The reasons for this stagnation are highly complex and multi-factorial. It remains that almost three billion treatment courses were supplied over the period 2010-2017: 30% of them without malaria tests, and some with suboptimal doses leading to the risk of selection of resistant parasites. An antimalarial stewardship program should be implemented at the healthcare provider, physician, pharmacist, medical student, and population levels...
