OBJECTIVES Mutations in the gyrase genes cause fluoroquinolone resistance in Mycobacterium tuberculosis. However, the predictive value of these markers for clinical outcomes in patients with MDR-TB is unknown to date. The objective of this study was to determine molecular markers and breakpoints predicting second-line treatment outcomes in M. tuberculosis patients treated with fourth-generation...

A reverse phase stability indicating HPLC method for simultaneous determination of two antispasmodic drugs in pharmaceutical parenteral dosage forms (injectable) and in serum has been developed and validated. Mobile phase ingredients consist of Acetonitrile : buffer : sulfuric acid 0.1 M (50 : 50 : 0.3 v/v/v), at flow rate 1.0 mL/min using a Hibar μ Bondapak ODS C18 column monitored at dual wav...

No information is currently available on the influence of injectable second-line drugs on treatment outcomes of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) patients. To investigate this issue, a large series of MDR- and XDR-TB cases diagnosed in Estonia, Germany, Italy and the Russian Federation (Archangels Oblast) between 1999 and 2006 were analysed. All st...

Biotechnology and pharmaceutical research have created a number of new and potentially life-saving drugs. Many of these drugs are formulated as injectable products. Some drug products do not survive autoclaving or other means of terminal sterilization. An aseptic filling process is typically used to sterilize such products, but it is less reliable than autoclaving, making detection of unsterile...

Mesenchymal stem cells (MSCs) can ameliorate renal injury and accelerate repair of acute kidney injury. Herein, we developed a collagen/poly(γ-glutamic acid) (γ-PGA) hydrogel as an injectable scaffold for the delivery of mouse MSCs (mMSCs) and anti-oxidant drugs into injured sites. By the introduction of γ-PGA into conventional collagen, the viscosity of collagen was reduced at ambient temperat...

Fish display robust neuroendocrine and physiologic stress responses to noxious stimuli. Many anesthetic, sedative, or analgesic drugs used in other vertebrates reduce stress in fi sh, decrease handling trauma, minimize movement and physiologic changes in response to nociceptive stimuli, and can be used for euthanasia. But extrapolating from limited published anesthetic and sedative data to all ...

A long-acting form of the second-generation antipsychotic drug risperidone is now broadly available for the treatment of schizophrenia and closely related psychiatric conditions. It combines the advantage of previously available depot formulations for first-generation drugs with the favorable characteristics of the modern "atypical" antipsychotics, namely higher efficacy in the treatment of the...

BACKGROUND There are limited studies on the prevalence and risk factors associated with hepatitis C virus (HCV) infection. Objective Identify the prevalence and risk factors for HCV infection in university employees of the state of São Paulo, Brazil. METHODS Digital serological tests for anti-HCV have been performed in 3153 volunteers. For the application of digital testing was necessary to w...

BACKGROUND Pharmacy benefits have historically excluded injectable drugs, resulting in coverage of injectable drugs under the medical benefit. High-cost biologics and other new drug therapies are often injectables and therefore have not presented cost threats to pharmacy benefits. The U.S. Food and Drug Administration approval of capecitabine, an oral form of fluorouracil, in 1998, and imatinib...

Trauma is the leading cause of death from age 1 to 34 years and is the fifth leading cause of death overall in the USA, with uncontrolled hemorrhage being the leading cause of potentially preventable death. Improving our ability to control hemorrhage may represent the next major hurdle in reducing trauma mortality. New techniques, devices, and drugs for hemorrhage control are being developed an...
