Shrikant R Mulay, Hans-Joachim Anders
Crystals can trigger a wide range of kidney injuries that can lead to acute kidney injury, chronic kidney disease, renal colic or nephrocalcinosis, depending on the localization and dynamics of crystal deposition. Studies of the biology of crystal handling by the kidney have shown that the formation of different crystals and other microparticles and the associated mechanisms of renal damage share molecular mechanisms, such as stimulation of the NLRP3 inflammasome or direct cytotoxicity through activation of the necroptosis signalling pathway...

HIV/AIDS remains a major public health issue. In 2014, it was estimated that 36.9 million people are living with HIV worldwide, including 2.6 million children. Since the advent of combination antiretroviral therapy (cART), in the 1990s, treatment has been so successful that in many parts of the world, HIV has become a chronic condition in which progression to AIDS has become increasingly rare. However, while people with HIV can expect to live a normal life span with cART, lifelong medication is required and cardiovascular, renal, liver, and neurologic diseases are still possible, which continues to prompt research for a cure for HIV...

Tuberculosis (TB) remains a threat to public health and is the second cause of death due to a single infectious agent after HIV/AIDS. The worldwide distribution of TB is heterogeneous. The incidence is decreasing in most high-income regions, but the situation remains worrying in many parts of the world. The emergence of Mycobacterium tuberculosis strains resistant to key agents used in treatment (rifampin and isoniazid) contributes to TB transmission around the world. To achieve TB elimination, both high and low endemic countries must upscale their efforts to decrease disease transmission and improve cure rates...

OBJECTIVES: At our institution, custom made antibiotic-laden cement nails fabricated during surgery using a thoracostomy catheter as a mold is commonly employed to treat long bone infection. As the outer diameter of the nails produced has not previously been described, we designed a study to measure the outer diameter of antibiotic-laden cement nails fashioned using commercially available and commonly utilized thoracostomy catheters of various sizes. METHODS: Six thoracostomy catheters from two different manufactures (Argyle™ PVC Thoracic Catheters, Covidien Ltd...

BACKGROUND: Surgical management of recurrent disease after total thyroidectomy and/or neck dissection for thyroid carcinoma remains a challenging clinical problem. Reoperation is associated with a significant increase in morbidity. Preoperative needle localization technique for non-palpable breast tumors has recently been extrapolated to head and neck surgery. We report on the use of preoperative ultrasound-guided needle localization for non-palpable recurrent operative bed disease as an intraoperative aid in resection...

This paper reflects on the meanings of 'post-AIDS' in the Global North and South. I bring together contemporary arguments to suggest that the notion of 'post-AIDS' is, at best, misplaced, not least because its starting point remains a biotechnical one. Drawing on aspects of the sub-Saharan African experience, this essay suggests that, despite significant shifts in access to antiretroviral therapy (ART), HIV continues to be fundamentally shaped by economic determinants and social and cultural practices. In this essay, I question the certainty of the discourse of (Western biomedical) 'positive progress' (Johnson et al...

Neurodegenerative diseases (NDDs) are the result of progressive deterioration of neurons, ultimately leading to disabilities. There is no effective cure for NDDs at present; ongoing therapies are mainly aimed at treating the most bothersome symptoms. Since early treatment is crucial in NDDs, there is an urgent need for specific and sensitive biomarkers that can aid in early diagnosis of these disorders. Recently, altered expression of miRNAs has been implicated in several neurological disorders, including NDDs...

REVIEW
Paul W Franks, Alaitz Poveda
Precision diabetes medicine, the optimisation of therapy using patient-level biomarker data, has stimulated enormous interest throughout society as it provides hope of more effective, less costly and safer ways of preventing, treating, and perhaps even curing the disease. While precision diabetes medicine is often framed in the context of pharmacotherapy, using biomarkers to personalise lifestyle recommendations, intended to lower type 2 diabetes risk or to slow progression, is also conceivable. There are at least four ways in which this might work: (1) by helping to predict a person's susceptibility to adverse lifestyle exposures; (2) by facilitating the stratification of type 2 diabetes into subclasses, some of which may be prevented or treated optimally with specific lifestyle interventions; (3) by aiding the discovery of prognostic biomarkers that help guide timing and intensity of lifestyle interventions; (4) by predicting treatment response...

OBJECTIVES: The BASHH guidelines recommend molecular tests to aid diagnosis of Trichomonas vaginalis (TV) infection; however many clinics continue to use relatively insensitive techniques (pH, wet-prep microscopy (WPM) and culture). Our objectives were to establish a laboratory pathway for TV testing with the Becton-Dickinson Qx (BDQx) molecular assay, to determine TV prevalence and to identify variables associated with TV detection. METHODS: A prospective study of 901 women attending two urban sexual health services for STI testing was conducted...

Integrating research experiences into undergraduate life sciences curricula in the form of course-based undergraduate research experiences (CUREs) can meet national calls for education reform by giving students the chance to "do science." In this article, we provide a step-by-step practical guide to help instructors assess their CUREs using best practices in assessment. We recommend that instructors first identify their anticipated CURE learning outcomes, then work to identify an assessment instrument that aligns to those learning outcomes and critically evaluate the results from their course assessment...

The acronym "CADD" is often used interchangeably to refer to "Computer Aided Drug Discovery" and "Computer Aided Drug Design". While the former definition implies the use of a computer to impact one or more aspects of discovering a drug, in this paper we contend that computational chemists are most effective when they enable teams to apply true design principles as they strive to create medicines to treat human disease. We argue that teams must bring to bear multiple sub-disciplines of computational chemistry in an integrated manner in order to utilize these principles to address the multi-objective nature of the drug discovery problem...

The present study was conducted to evaluate the effects of an experimental adhesive agent [methyl methacrylate-tributylborane liquid (MT)] and two adhesive agents containing silane on the bonding between a resin composite block of a computer-aided design and manufacturing (CAD/CAM) system and a light-curing resin composite veneering material. The surfaces of CAD/CAM resin composite specimens were ground with silicon-carbide paper, treated with phosphoric acid, and then primed with either one of the two silane agents [Scotchbond Universal Adhesive (SC) and GC Ceramic Primer II (GC)], no adhesive control (Cont), or one of three combinations (MT/SC, MT/GC, and MT/Cont)...

Traditional Chinese herbal medicine (TCM) has been used in Chinese society for more than 5,000 years to treat diseases from inflammation to cancer. Here, we report the case of nine living AIDS patients in the age range of 51 to 67 who were treated with either a unique formula of TCM alone from 2001 to 2009 or the TCM from 2001 to 2006 and then switched to occasional antiretroviral therapy. Surprisingly, the viral loads of eight patients were at undetectable levels on June 28, 2016, while the remaining patient had a low viral load of 29 copies/ml...

The patient empowerment movement, spurred by AIDS activism in the 1980s, quickly evolved to encompass how study participants are considered and treated in clinical research. Initially, people fearing death of AIDS sought early access to experimental medications that had not undergone rigorous testing in hopes of extending their lives. Thirty years on, scientists are asking a different set of ethical questions about clinical research, this time in the pursuit of either a sterilising cure or long-term remission for HIV...

OBJECTIVE: The Revised Illness Perceptions Questionnaire (IPQ-R), widely used to assess illness perceptions, may fail to measure unique characteristics of different illnesses. This study modified and validated the IPQ-R for breast cancer survivors to provide detailed understanding of the specific illness perceptions held by these patients. DESIGN: Initial modifications were made following qualitative interviews and were revised in a think-aloud study. The modified scale was tested in 753 breast cancer survivors prescribed tamoxifen...

PURPOSE: The two commonly used radiotherapy techniques are total body irradiation (TBI) and the total skin irradiation (TSI). In order to ensure the accuracy of the prescription beams, the dose received throughout the entire body must be checked using dosimetry. However, the available number of data points is limited as the dosimeters are manually placed on the patient. We developed a flexible and wearable dosimeter that can collect 1D continuous dose information around the peripheral of the patients' body, including areas obscured from the beam path...

BACKGROUND: Parathyroidectomy offers the only cure for primary hyperparathyroidism, but today only 50% of primary hyperparathyroidism patients are referred for operation, in large part, because the condition is widely under-recognized. The diagnosis of primary hyperparathyroidism can be especially challenging with mild biochemical indices. Machine learning is a collection of methods in which computers build predictive algorithms based on labeled examples. With the aim of facilitating diagnosis, we tested the ability of machine learning to distinguish primary hyperparathyroidism from normal physiology using clinical and laboratory data...

The blood-brain barrier (BBB) represents a major obstacle for the delivery and development of drugs curing brain pathologies. However, this biological barrier presents numerous endogenous specialized transport systems that can be exploited by engineered nanoparticles to enable drug delivery to the brain. In particular, conjugation of glutathione (GSH) onto PEGylated liposomes (G-Technology(®)) showed to safely enhance delivery of encapsulated drugs to the brain. Yet, understanding of the mechanism of action remains limited and full mechanistic understanding will aid in the further optimization of the technology...
