STUDY QUESTION: Is the thrombophilia mutation factor V Leiden (FVL) associated with an increased total sperm count? SUMMARY ANSWER: Carriers of FVL have a higher total sperm count than non-FVL-carriers, which could not be explained by genetic linkage or by observations in a FVL-mouse model. WHAT IS KNOWN ALREADY: FVL has a high prevalence in Caucasians despite detrimental health effects. Carriers have been shown to have higher fecundity, which might partly explain this evolutionary paradox...

Cerium oxide nanoparticles (nanoceria), well known for their pro- and antioxidant features, have been recently proposed for the treatment of several pathologies, including cancer and neurodegenerative diseases. However, interaction between nanoceria and biological molecules such as proteins and lipids, short blood circulation time, and the need of a targeted delivery to desired sites are some aspects that require strong attention for further progresses in the clinical application of these nanoparticles. The aim of this work is the encapsulation of nanoceria into a liposomal formulation in order to improve their therapeutic potentialities...

The incidence of pancreatic cancer has been obviously increasing in China over the last decade, however, those patients with advanced pancreatic cancer are suffering from limited treatment strategies and poor clinical prognosis. Chemotherapy improved the overall survival of cases with advanced pancreatic cancer to 8-11 months, and erlotinib brought an additional survival of only 10 days. In this article, the recent progresses on advanced pancreatic cancer were reviewed at the genetic and molecular sub-typing levels, and corresponding clinical transformation studies summarized, some of which have showed encouraging clinical prospects but others have failed due to the complexity of pancreatic cancer...

Currently, immunotherapy is considered as the fourth major modality of cancer treatment except surgery, chemotherapy and radiotherapy. The new therapeutic approach based on immune checkpoint inhibitors is a landmark innovation. Strategies considering checkpoint inhibitors have shown good anti-tumor effect by targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1) or programmed cell death ligand 1 (PD-L1). Moreover, DNA mismatch repair-deficient tumors appear to be potential candidates for these therapies...

Colorectal cancer is one of the leading causes of morbidity and mortality around the world. Although the staging and classification systems, such as tumor/node/metastasis (TNM) staging, are widely used in clinic, there are some limitations. For example, the patients with the same pathological type, TNM stage and treatment regimen show a completely different prognosis and outcome. In the present, molecular subtyping was concerned for a more precise and accurate staging of colorectal cancer. Herein, we reviewed the literature of the molecular subtypes of colorectal cancer in the past decades...

Dry eye is the second most common ocular disease. In China, the incidence rate of dry eye has reached 21% to 30%, and dry eye patients have accounted for more than 30% of the total ophthalmology outpatients. Dry eye has become a common health problem that affects the working efficiency and life quality of Chinese people. Over the past decade, due to the rapid development of diagnostic equipments and new treatments for dry eye, dry eye has become one of the areas with greatest concerns in ophthalmology, and many eye institutions have set up their dry eye clinics...

With the development of society and the improvement of medical level, the average life span of human has been increasing year by year. The proportion of elderly burn patients is also increasing yearly, which has become a social problem that can not be ignored. Because of physiological characteristics, such as decreased function of heart, lung, and kidney, degenerative changes of neural system, reduced gastrointestinal function and immunological function, and mostly accompanied by primary diseases of diabetes and cardiovascular diseases, elderly burn patients suffer from high shock rate and mortality, and their wounds are not easy to heal...

Although gilt silver threads were widely used for decorating historical textiles, their manufacturing techniques have been elusive for centuries. Contemporary written sources give only limited, sometimes ambiguous information, and detailed cross-sectional study of the microscale soft noble metal objects has been hindered by sample preparation. In this work, to give a thorough characterization of historical gilt silver threads, nano- and microscale textural, chemical and structural data on cross sections, prepared by focused ion beam milling, were collected, using various electron-optical methods (high-resolution scanning electron microscopy (SEM), wavelength-dispersive electron probe microanalysis (EPMA), electron back-scattered diffraction (EBSD) combined with energy-dispersive electron probe microanalysis (EDX), transmission electron microscopy (TEM) combined with EDX, and micro-Raman spectroscopy...

Teneurins are transmembrane proteins consisting of four paralogues (Ten-1-4), notably expressed in the central nervous system during development. All teneurins contain a bioactive peptide in their carboxyl terminal named teneurin C-terminal associated peptide (TCAP). The present study analyzed the detailed distribution of teneurin-2-like immunoreactive (Ten-2-LI) cells in developing and mature rat molar teeth, as well as in mature human dental pulps. Ten-2 and TCAP-2 genic expressions were also evaluated in rat and human dental pulps...

The purpose of this study was to evaluate narrower age groups in children aged 0-4 years to determine whether guidelines should be refined when investigating femur fractures for nonaccidental trauma (NAT). This was a retrospective review of the pediatric trauma database at our level 1 pediatric trauma center. The database was examined from 2009 to present. We examined rates of NAT in the less than or equal to 12-month, 13-24-month, 25-36-month, and 37-48-month age groups. χ was used to compare rates of NAT between these groups, and P less than 0...
