The treatment of multidrug-resistant tuberculosis (MDR-TB) is a challenge to be overcome. The increase of resistant isolates associated with serious side effects during therapy leads to the search for substances that have anti-TB activity, which make treatment less toxic, and also act in the macrophage acidic environment promoted by the infection. The aim of this study was to investigate lapachol and β-lapachone activities in combination with other drugs against at neutral and acidic pH and its cytotoxicity.

To the best of our knowledge, there is no standardization among researchers regarding the technique used to detect a drug's MBC in . Thus, the aim of this systematic review is to discuss the available literature in determining a drug's MBC in , to find the most commonly used technique and standardize the process.

Objective: Herein, we determined the (i) activities of (-)-camphene and its derivatives and (ii) combinatory effect with pyrazinamide (PZA) against Mycobacterium tuberculosis in acidic pH and (iii) cytotoxicity on VERO cells.
Methods: The activity of (-)-camphene and its 15 derivatives was determined in M.
Importance: Hypothyroidism is one of the most prevalent diseases in pregnancy, but there is no consensus about its management in pregnant women.
Objective: In this systematic review, we evaluated the association between pregnancy complications and treated or untreated maternal hypothyroidism.
Evidence Acquisition: PubMed and reference lists were searched for the Medical Subject Headings terms "pregnancy complications" and "hypothyroidism.
Antiphospholipid syndrome (APS) is an autoimmune condition that is associated with thrombosis and morbidity in pregnancy. The exact mechanisms by which these associations occur appear to be heterogeneous and are not yet well understood. The aim of this study was to identify and analyze publications in recent years to better understand the diagnosis and its contribution to monitoring APS among women with recurrent miscarriage (RM).
