The field of pharmaceutical cocrystals has reached a tipping point, particularly because cocrystals can improve the physicochemical properties of drugs without compromising their therapeutic benefit. Accounts of cocrystal investigations in the literature started in earnest in 2003 and patent applications soon followed. The frequency of both has steadily accelerated, demonstrating an enhanced understanding of the design, characterisation, and manufacture of cocrystals and heightened interest from industry. Read More

Schistosomiasis, the most common water-borne infection worldwide, continues to pose a serious public health challenge in developing nations and to travellers who visit these endemic regions. We apply optimal control on a temperature dependent schistosomiasis model. Our optimal control aims to minimize the pre-patent and patent human population at minimal costs. Read More

This study was undertaken to evaluate a novel method for stabilizing and preserving the original proportion of cell-free fetal DNA (cffDNA) in maternal blood for extended periods of time without using crosslinking agents, such as formaldehyde, which compromise DNA integrity and extraction efficiency. Blood was drawn from pregnant donors into K3EDTA and Blood Exo DNA ProTeck® (ProTeck) tubes. Blood drawn into both tubes were aliquoted and stored at three different temperatures. Read More

Subjects with a patent foramen ovale (PFO) have blunted ventilatory acclimatization to high altitude, compared to subjects without PFO. The blunted response observed could be due to differences in central and/or peripheral respiratory chemoreflexes. We hypothesized that compared to subjects without a PFO (PFO-), subjects with a PFO (PFO+) would have blunted ventilatory responses to acute hypoxia and hypercapnia. Read More

Transcranial Doppler (TCD) is useful for investigation of intracranial arterial blood flow and can be used to detect a real-time embolic signal. Unfortunately, artefacts can mimic the embolic signal, complicating interpretation and necessitating expert-level opinion to distinguish the two. Resolving this situation is critical to achieve improved accuracy and utility of TCD for patients with disrupted intracranial arterial blood flow, such as stroke victims. Read More

Protein kinases undergo large-scale structural changes that tightly regulate function and control recognition by small-molecule inhibitors. Methods for quantifying the conformational effects of inhibitors and linking them to an understanding of selectivity patterns have long been elusive. We have developed an ultrafast time-resolved fluorescence methodology that tracks structural movements of the kinase activation loop in solution with angstrom-level precision, and can resolve multiple structural states and quantify conformational shifts between states.

The detection and analysis of rare blood biomarkers is necessary for early diagnosis of cancer and to facilitate the development of tailored therapies. However, current methods for the isolation of circulating tumour cells (CTCs) or nucleic acids present in a standard clinical sample of only 5-10 ml of blood provide inadequate yields for early cancer detection and comprehensive molecular profiling. Here, we report the development of a flexible magnetic wire that can retrieve rare biomarkers from the subject's blood in vivo at a much higher yield. Read More

Acute graft-versus-host disease (GVHD) targets the crypts in the gastrointestinal (GI) tract that are responsible for the self-renewal of the intestinal mucosa. Recent advances in the identification and culture of intestinal stem cells have improved our understanding of the interactions between the microbiome and the immune system (both innate and adaptive) that are key to the pathophysiology of GVHD. The identification of serum biomarkers that best predict long-term GVHD outcomes derive from the GI tract and have focused attention on cellular elements that act as shields against GVHD as well as its targets.

Stroke, one of the main causes of disability and death worldwide, is frequently associated to the obstructive sleep apnea-hypopnea syndrome. This sleep disorder has been demonstrated to be an independent risk factor for stroke, and therefore its investigation and treatment has been recommended for patients with stroke. Mechanisms relating these two clinical disorders include: oxidative stress, cerebral blood flow alterations, autonomic dysfunction, and hypercoagulability, as well as patent foramen ovale, blood pressure, and heart rhythm disorders.

Background: Hematopoietic cell transplantation (HCT) is accepted therapy for severe mucopolysaccharidosis type I (MPS IH). With implementation of newborn screening (NBS) for MPS I in the US, HCT may now occur earlier than 1-2 years of age and it might be assumed that cardiac issues will be fewer. To examine this hypothesis, we reviewed our records for any MPS IH infant who underwent HCT at ≤6 months of age. Read More

The human oocyte zona pellucida (ZP) is made of four glycoproteins, ZP1-ZP4. Recently, the prostate adenocarcinoma and prostate cancer PC3 cell-line were shown to express the human oocyte ZP3 glycoprotein, which was evaluated in a single report subject to patent. To further clarify whether oocyte zona pellucida glycoproteins are expressed in prostate cancer tissue and PC3-cells, in this report we evaluated protein expression of the four ZP glycoproteins in normal prostate tissue, prostate adenocarcinoma tissue and PC3-cells, and performed quantitative mRNA expression of the four ZP glycoproteins in the PC3 cell-line.

Objectives: To develop and test a method for approximating generic entry of top-selling drugs.
Methods: The procedure involved 1) identifying products' key patents as those with a patent term restoration extension (whenever relevant) or otherwise as the first expiring patent listed in the US Food and Drug Administration's patent register, 2) determining whether the key patent had been extended through an associated pediatric extension, 3) identifying other regulatory exclusivities associated with the drug, and 4) categorizing key patents as active ingredient (or extended) patents versus secondary patents. The accuracy and precision of the procedure's predictions were then tested against a database containing the timing of generic entry for 170 top-selling drugs that lost market exclusivity between 2000 and 2012, on the basis of Medicaid data.

Objectives: Surgical repair in patients with acute DeBakey type I aortic dissection (ADIAD) achieves good short-term results, but in several patients the false lumen remains patent in the descending aorta because of distal intimal tears with persisting risk for distal aneurismal evolution.

Pharmaceuticals: is there a just price for innovation? The « Sovaldi case », a very effective and very expensive drug targeting a relatively large population, marks an evolution of the «business model» of pharmaceutical innovations. This latter was traditionally split between expensive drugs in narrow indications (targeted treatments, orphan diseases) and drugs addressing a wider population at moderate costs, at least not commensurate with that of contemporary innovations. Even if these prices - resulting in from an undisputable financialization of advanced medical research - raise a legitimate emotion among health care professionals and in the public opinion, even if regulators impose price cuts, at least in Europe, these treatments - that can be «efficient» in a health economic sense - raise serious funding problems.

Archaeosomes are liposomes traditionally comprised of total polar lipids (TPL) or semi-synthetic glycerolipids of ether-linked isoprenoid phytanyl cores with varied glyco- and amino-head groups. As adjuvants, they induce robust, long-lasting humoral and cell-mediated immune responses and enhance protection in murine models of infectious disease and cancer. Traditional total polar lipid (TPL) archaeosome formulations are relatively complex and first generation semi-synthetic archaeosomes involve many synthetic steps to arrive at the final desired glycolipid composition.
