Leming Sun, Yanzi Hu, Lianbing Zhang
BACKGROUND: As the quick development of modern methods and technologies currently, more and more drugs have been invented with a better efficiency. However, the poor water solubility has limited the drugs' pharmaceutical application. METHODS: Tremendous research has been put in the design and development of nanocrystals for pharmaceutical applications over the past few decades. The nanocrystals not only have the chance to solve the poor solubility problem, but also could conquer the bioavailability and even the specific delivery problems...

REVIEW
Mark Webster
Morphological homeostasis limits the extent to which genetic and/or environmental variation is translated into phenotypic variation, providing generation-to-generation fitness advantage under a stabilizing selection regime. Depending on its lability, morphological homeostasis might also have a longer-term impact on evolution by restricting the variation-and thus the response to directional selection-of a trait. The fossil record offers an inviting opportunity to investigate whether and how morphological homeostasis constrained trait evolution in lineages or clades on long timescales (thousands to millions of years) that are not accessible to neontological studies...

The future supply of energy to meet growing energy demand of rapidly exapanding populations is based on wide energy resources, particularly the renewable ones. Among all resources, lignocellulosic biomasses such as agriculture, forest, and agro-industrial residues are the most abundant and easily available bioresource for biorefineries to provide fuels, chemicals, and materials. However, pretreatment of biomass is required to overcome the physical and chemical barriers that exist in the lignin-carbohydrate composite and pretreatment facilitate the entry of biocatalysts for the conversion of biomass into fermentable sugars and other by-products...

A universal turnaround has been detected in many countries of the World from shrinking to expanding forests. The forest area of western Europe expanded already in the 19th century. Such early trends of forest resources cannot be associated with the rapid rise of atmospheric carbon dioxide nor with the anthropogenic climate change, which have taken place since the mid 20th century. Modern, most recent spatial patterns of forest expansions and contractions do not correlate with the geography of climate trends nor with dry versus moist areas...

Creating artificial systems that mimic and surpass those found in nature is one of the great challenges of modern science. In the context of photosynthetic light harvesting, the difficulty lies in attaining utmost control over the energetics, positions and relative orientations of chromophores in densely packed arrays to transfer electronic excitation energy to desired locations with high efficiency. Toward achieving this goal, we use a highly versatile biomimetic protein scaffold from the tobacco mosaic virus coat protein on which chromophores can be attached at precise locations via linkers of differing lengths and rigidities...

REVIEW
L Paninski, J P Cunningham
Modern large-scale multineuronal recording methodologies, including multielectrode arrays, calcium imaging, and optogenetic techniques, produce single-neuron resolution data of a magnitude and precision that were the realm of science fiction twenty years ago. The major bottlenecks in systems and circuit neuroscience no longer lie in simply collecting data from large neural populations, but also in understanding this data: developing novel scientific questions, with corresponding analysis techniques and experimental designs to fully harness these new capabilities and meaningfully interrogate these questions...

The advances in biotechnology, biomechanics, and biomaterials can be used to develop organ models that aim to accurately emulate their natural counterparts. Heart disease, one of the leading causes of death in modern society, has attracted particular attention in the field of tissue engineering. To avoid incorrect prognosis of patients suffering from heart disease, or from adverse consequences of classical therapeutic approaches, as well as to address the shortage of heart donors, new solutions are urgently needed...

BACKGROUND: Parasitic diseases are one of the world's most devastating and prevalent infections which cause millions of morbidities and mortalities annually. In the past, many of these infections have been linked predominantly to tropical or subtropical areas. Nowadays, however, climatic and vector ecology changes, a significant increase in international travel, armed conflicts and migration of humans and animals have influenced the transmission of some parasitic diseases from "book pages" to reality in developed countries...

Virtual surgical planning (VSP), computer-aided design and computer-aided modeling, and 3-dimensional printing are 3 distinct technologies that have become increasingly used in head and neck oncology and microvascular reconstruction. Although each of these technologies has long been used for treatment planning in other surgical disciplines, such as craniofacial surgery, trauma surgery, temporomandibular joint surgery, and orthognathic surgery, its widespread use in head and neck reconstructive surgery remains a much more recent event...

The degrading influence of noise on various critical bands of speech was assessed. A modified version of the compound method [Apoux and Healy (2012) J. Acoust. Soc. Am. 132, 1078-1087] was employed to establish this noise susceptibility for each speech band. Noise was added to the target speech band at various signal-to-noise ratios to determine the amount of noise required to reduce the contribution of that band by 50%. It was found that noise susceptibility is not equal across the speech spectrum, as is commonly assumed and incorporated into modern indexes...

Clare Griffin
This article deals with the trade in medicines into Russia in the seventeenth century. Both the early modern medical drug trade, and Russian medicine, have previously received substantial attention, but no work has thus far been undertaken on the Russian angle of the drug trade. Drawing on previously unused documents, this article traces the kinds of drugs acquired by the Moscow court. In contrast to the dominant view of official Russian medicine as divorced from native healing practices and fundamentally reliant upon Western European trends, these documents reveal that drugs were sourced as locally as Moscow markets, and from as far afield as East Asia and the Americas, but that not all drugs were accepted...

BACKGROUND: Crystal methamphetamine (ice) has become the substance of choice among young men who have sex with men (YMSM) in urban Thailand. Yet, there is scarce data on this phenomenon, partly due to the difficulty in accessing men who will disclose and openly discuss the social contexts, meanings and risks surrounding ice practice. We present an ethnography of ice parties, critically discussing the in-depth social meanings of ice; the sexual socialities and the secrecy surrounding its use; the transactions between older and younger men; and the role of the Internet and mobile technology...
