Michael Siderius, Filip Jagodzinski
Understanding how an amino acid substitution affects a protein's structure can aid in the design of pharmaceutical drugs that aim at countering diseases caused by protein mutants. Unfortunately, performing even a few amino acid substitutions in vitro is both time and cost prohibitive, whereas an exhaustive analysis that involves systematically mutating all amino acids in the physical protein is infeasible. Computational methods have been developed to predict the effects of mutations, but even many of them are computationally intensive or are else dependent on homology or experimental data that may not be available for the protein being studied...

Genetic polymorphisms in blood donors may contribute to donor-specific differences in the survival of red blood cells (RBCs) during cold storage and after transfusion. Genetic variability is anticipated to be high in donors with racial admixture from malaria endemic regions such as Africa and Asia. The purpose of this study was to test the hypothesis that donor genetic background, reflected by sex and self-reported ethnicity, significantly modulates RBC phenotypes in storage. High throughput hemolysis assays were developed and used to evaluate stored RBC samples from 11 115 African American, Asian, white, and Hispanic blood donors from 4 geographically diverse regions in the United States...

Potentially useful in the treatment of neurodegenerative disorders, Kaempferia parviflora and Myristica fragrans have been shown to possess a wide spectrum of neuropharmacological activities and neuroprotective effects in vivo and in vitro. In this study, we determined whether and how K. parviflora ethanolic extract and M. fragrans volatile oil could influence the levels of neurotransmitters and the whole proteomic profile in the hippocampus of Sprague Dawley (SD) rats. The effects of K. parviflora and M...

Anxiolytic drugs are widely used in the elderly, a population particularly sensitive to stress. Stress, aging and anxiolytics all affect low-frequency oscillations in the hippocampus and prefrontal cortex (PFC) independently, but the interactions between these factors remain unclear. Here, we compared the effects of stress (elevated platform, EP) and anxiolytics (diazepam, DZP) on extracellular field potentials (EFP) in the PFC, parietal cortex and hippocampus (dorsal and ventral parts) of adult (8 months) and aged (18 months) Wistar rats...

While topical medications remain the cornerstone of the psoriasis treatment paradigm, they also come with the risk of multiple side effects. An alternative topical treatment option, calcipotriene or calcipotriol, is a vitamin D derivative that is thought to work by inhibiting keratinocyte proliferation and enhancing keratinocyte differentiation. Multiple studies have demonstrated its efficacy and safety in improving psoriasis when used in combination with topical corticosteroids. Given the effectiveness and side effect profile seen with this combination of topical steroid and calcipotriene, the US Food and Drug Administration approved a calcipotriene/betamethasone dipropionate product for use in psoriasis patients over the age of 12 in 2006...

Due to the continued increase in global spending on health care, payers have introduced a number of programs, policies, and agreements on pharmaceutical pricing in order to control costs. While incentives to increase generic drug use have achieved significant savings, other cost-containment measures are required. Tendering is a formal procedure to purchase medications using competitive bidding for a particular contract. Although useful for cost containment, tendering can lead to decreased competition in a given market...

BACKGROUND: The standard postsurgical options for low-grade gliomas include watchful waiting or radiotherapy depending on the risk factors for recurrence. The use of chemotherapy for the treatment of this disease is generally controversial, although the recently published results of the first of two large randomized phase III clinical trials (RTOG 9802 a EORTC 22033-26033), focusing on the evaluation of chemotherapy for the upfront treatment of newly diagnosed low-grade gliomas, are reassuring in this respect...

BACKGROUND: The optimal treatment for low-grade gliomas remains controversial. Neurosurgery, radiotherapy, and chemotherapy are the main treatment options. Despite advances in oncology, there are still a lot of uncertainties, and the optimal sequences, combinations, and timings of these procedures have not yet been optimized. It is still unclear whether temozolomide can replace effective, but toxic PCV chemotherapy (procarbazine, lomustine, vincristine) and whether temozolomide can be used upfront alone instead of radiotherapy alone...

Processing equipment involving grinding of two solid surfaces has been demonstrated to induce subvisible particle (SvP) formation in monoclonal antibody (mAb) drug product manufacturing processes. This study elucidated potential stress types associated with grinding action to identify the stress mechanism responsible for SvP formation. Several potential stress types can be associated with the grinding action, including interfacial stresses (air-liquid and liquid-solid), hydraulic/mechanical shear stress, cavitation, nucleation of stressed protein molecules, and localized thermal stress...

The new psychoactive substances phenomenon continues to represent a considerable public health challenge. Synthetic cathinones are β-keto amphetamine analogues, also known as legal highs, research chemicals, bath salts. These drugs have surfaced as a popular alternative to other illicit drugs of abuse, such as cocaine, MDMA, and methamphetamine, due to their potent psychostimulant and empathogenic effects. Pyrovalerone cathinones (a-pyrrolidinophenones) form a distinct group of designer cathinones, such as MDPV...

Background: Cardiovascular disease (CVD) is expected to contribute a large non-communicable disease burden amongst HIV-positive people. We quantify the impact of prevention interventions on annual CVD burden and costs amongst HIV-positive people in The Netherlands. Methods: We constructed an individual-based model of CVD in HIV-positive people using national ATHENA cohort data on 8,791 patients on combination antiretroviral therapy (cART). The model follows patients as they age, develop CVD (by incorporating a CVD risk equation) and start cardiovascular medication...

Background: The increase in antibiotic resistance in Gram-negative bacteria and the limited therapeutic options due to the shortage of new antibiotics have increased the interest of the 'old' antibiotic fosfomycin in the treatment of infections. However, there are contradictory reports on the pharmacodynamics of and emergence of resistance to fosfomycin. Methods: Time-kill assays were performed with 11 ESBL-positive and 3 ESBL-negative strains, exposing the bacteria to 2-fold static concentrations from 0...

BACKGROUND: Policing practices such as syringe confiscation and arrest can act as important social-structural drivers of HIV risk among people who inject drugs (PWID). However, police referral to treatment and other services may improve the health of PWID. Little is known about the role of modifiable attitudinal and knowledge factors in shaping officer behavior. Using baseline findings from a police education program (PEP), we assessed relationships between drug policy knowledge and attitudes towards public health interventions with self-reported syringe confiscation, drug arrest, and service referral among street-level police in Tijuana, Mexico...

BACKGROUND: High drug spending is a concern for policy makers due to limits on access for patients. Numerous policies have been proposed to address high drug spending. The existence of multifarious proposals makes it difficult for policy makers to consider all the alternatives. We developed an approach to select the most viable options to present to policy makers. METHODS: We identified 41 different proposals in the peer-reviewed literature to reduce the level of spending or change the incentives for branded prescription drugs; ten of which we identified as promising proposals...

Novel therapies for multidrug-resistant tuberculosis (MDR-TB) are likely to be expensive. The cost of novel drugs (e.g., bedaquiline, delamanid) may be so prohibitively high that a traditional cost-effectiveness analysis (CEA) would rate regimens containing these drugs as not cost-effective. Traditional CEA may not appropriately account for considerations of social justice, and may put the most disadvantaged populations at greater risk. Using the example of novel drug regimens for MDR-TB, we propose a novel methodology, 'justice-enhanced CEA', and demonstrate how such an approach can simultaneously assess social justice impacts alongside traditional cost-effectiveness ratios...

BACKGROUND: Asymptomatic left ventricular (LV) dysfunction is highly prevalent in type 2 diabetes patients. Unlike the other hypoglycemic drugs, SGLT2 inhibitors have shown potential benefits for reducing cardiovascular death and risk factors, aside from lowering plasma glucose levels. With this study we aim at determining whether the treatment with empagliflozin is associated with an improvement in LV functions in diabetic patients with asymptomatic LV dysfunction against Sitagliptin, which is presumably neutral on myocardial function...
