Mucormycosis is uncommon in patients with chronic granulomatous disease (CGD). We report a 7-year-old boy with X-linked CGD and absent oxidative burst who developed fatal Lichtheimia ramosa infection with fungal thrombosis of the kidneys, spleen, and other organs following hematopoietic stem cell transplantation (HSCT). Lichtheimia infection is rarely reported in patients with CGD and could be related to iatrogenic immunosuppression.

The objective of this study is to determine how a hibernating mammal avoids the formation of blood clots under periods of low blood flow. A microfluidic vascular injury model was performed to differentiate the effects of temperature and shear rate on platelet adhesion to collagen. Human and ground squirrel whole blood was incubated at 15 or 37 °C and then passed through a microfluidic chamber over a 250-µm strip of type I fibrillar collagen at that temperature and the shear rates of 50 or 300 s(-1) to simulate torpid and aroused conditions, respectively...

Effective endosomal escape remains as the "holy grail" for endocytosis-based intracellular drug delivery. To date, most of the endosomal escape strategies rely on small molecules, cationic polymers, or pore-forming proteins, which are often limited by the systemic toxicity and lack of specificity. We describe here a light-fueled liquid-metal transformer for effective endosomal escape-facilitated cargo delivery via a chemical-mechanical process. The nanoscale transformer can be prepared by a simple approach of sonicating a low-toxicity liquid-metal...

Due to its strong genetic validation, NaV1.7 has attracted significant interest as a target for the treatment of pain. We have previously reported on a number of structurally distinct bicyclic heteroarylsulfonamides as NaV1.7 inhibitors that demonstrate high levels of selectivity over other NaV isoforms. Herein, we report the discovery and optimization of a novel series of atropisomeric quinolinone sulfonamide inhibitors of NaV1.7, which demonstrate nanomolar inhibition of NaV1.7 and exhibit high levels of selectivity over other sodium channel isoforms...

How stress influences brain repair is an issue of considerable importance, as patients recovering from stroke are known to experience high and often unremitting levels of stress post-event. In the current study, we investigated how chronic stress modified the key cellular components of the neurovascular unit. Using an experimental model of focal cortical ischemia in male C57BL/6 mice, we examined how exposure to a persistently aversive environment, induced by the application of chronic restraint stress, altered the cortical remodeling post-stroke...

Monounsaturated fatty acids (MUFAs) are unsaturated fatty acids with one double bond and are derived from endogenous synthesis and dietary intake. Accumulating evidence has suggested that plasma and erythrocyte MUFA levels were associated with cardiometabolic disorders including cardiovascular disease (CVD), type 2 diabetes (T2D) and metabolic syndrome (MS). Previous genome-wide association studies (GWAS) have identified seven loci for plasma and erythrocyte palmitoleic acid and oleic acid levels in populations of European origin...

Prior investigations on the associations of polyfluoroalkyl substances (PFASs) with fetal growth are mixed. Moreover, little research has accrued pertaining to the association between isomers of PFASs with gestational age and birth weight. To address this gap and present novel information, we conducted a study including 321 pairs of mothers and their infants recruited from Guangzhou, China. High performance liquid chromatography-mass spectrometry was utilized to analyze isomers of perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA) along with other PFAS levels in cord serum samples...

Hepatitis B virus (HBV) infection shows significant gender-related differences in pathogenesis, disease progression, and development of hepatocellular carcinoma. The gender-associated differences in HBV replication and viral protein levels may be associated with distinct HBV-specific immune responses in the host. In the present study, we examined the impact of gender on HBV-specific immune responses in two different mouse models representing transient and persistent hepadnaviral infection; hydrodynamic injection (HI) with the HBV genome mimicked acute HBV infection, whereas the efficacy of therapeutic vaccination was studied in the woodchuck hepatitis virus (WHV) transgenic (Tg) mouse model...

Background After peripheral nerve injury, there is an increase in calcium concentration in the injured nerves. Our previous publications have shown that increase in calcium concentration correlated well with degree of nerve injury and that local infusion of calcitonin has a beneficial effect on nerve recovery. Schwann cells play a pivotal role in regeneration and recovery. We aim to examine cultured Schwann cell survivals in various concentrations of calcium-containing growth media and the effect of calcitonin in such media...

Altered expression of the Fas ligand (FasL)/Fas ratio exhibits a direct impact on the prognosis of cancer patients and its impairment in cancer cells may lead to apoptosis resistance. Thus, the development of effective therapies targeting the FasL/Fas system may play an important role in the fight against cancer. In this study, we evaluated whether fusion of a protein (hcc49scFv-FasL) of the cytotoxicity domain of the FasL to a humanized antibody (CC49) against tumor-associated glycoprotein 72, which is expressed on oral squamous cell carcinoma (OSCC), can selectively kill OSCC cells with different FasL/Fas ratios...

Metastasis is a predominant cause of death for prostate cancer (PCa) patients; however, the underlying mechanisms are poorly understood. We report that monoamine oxidase A (MAOA) is a clinically and functionally important mediator of PCa bone and visceral metastases, activating paracrine Shh signaling in tumor-stromal interactions. MAOA provides tumor cell growth advantages in the bone microenvironment by stimulating interleukin-6 (IL6) release from osteoblasts, and triggers skeletal colonization by activating osteoclastogenesis through osteoblast production of RANKL and IL6...

In the USA, there are approximately 12,000 new cases of spinal cord injury (SCI) each year and some 1.2 million people living with paralysis due to SCI. Seven percent of them are paralyzed due to an accident or injury occurring while serving in the military. Here, we report a systematic study on protein biomarker candidates in a rat SCI model with either moderate or severe injury. Tissue, cerebrospinal fluid (CSF), and serum samples were obtained at 4 h, 24 h, and 7 days post-injury. The candidate biomarkers included axonal injury markers αII-spectrin breakdown products (SBDP150/145/120), neuronal cell body injury marker ubiquitin C-terminal hydrolase-L1 (UCH-L1), astrogliosis/astroglial injury markers S100 calcium-binding protein-β (S100β), glial fibrillary acidic protein (GFAP) and GFAP breakdown products (GBDPs), demyelination marker myelin basic protein (MBP), axonal injury marker phosphorylated neurofilament-H (pNF-H), and neuroinflammation marker interleukin-6 (IL-6)...
