Therapeutic interventions after spinal cord injury (SCI) routinely are designed to address multiple aspects of the primary and/or secondary damage that occurs. Exercise has a demonstrated efficacy for post-SCI complications such as cardiovascular dysfunction, neuropathic pain and chronic inflammation yet there is little understanding of the mechanisms by which improvements might result from this non-invasive approach. Here we review several of our observations of molecular and cellular changes within the injured spinal cord following acute or delayed exercise regimens that illustrate the potential for positive effects on neuroprotection and rehabilitation...

BACKGROUND: Orthopaedics and traumatology departments are dominated by patients with proximal femoral fractures, who represent 20-30% of all patients treated there. The aim of this study was identification and evaluation of factors influencing treatment of proximal femoral fractures. MATERIAL AND METHODS: Between 2008 and 2015, we treated 424 femoral neck fractures and 442 trochanteric fractures in patients over 40 y/o. The impact of fracture location (femoral neck/trochanteric), character (non-displaced/displaced) and the patient's general condition (metrical/biological age, health condition) on qualification and treatment used (fixations/hip pro-sthesis/non-operative) was analyzed...

INTRODUCTION: 4DCT-ventilation is an exciting new imaging modality that uses 4DCT data to calculate lung-function maps. Because 4DCTs are acquired as standard of care for lung cancer patients undergoing radiotherapy, 4DCT-ventiltation provides functional information at no extra dosimetric or monetary cost to the patient. The development of clinical trials is underway to use 4DCT-ventilation imaging to spare functional lung in patients undergoing radiotherapy. The purpose of this work was to perform a virtual trial using retrospective data to develop the practical aspects of a 4DCT-ventilation functional avoidance clinical trial...

BACKGROUND: The addition of oxaliplatin to adjuvant treatment regimens for colorectal cancer has been shown to improve overall survival at the expense of increased toxicity. The incidence and severity of toxicity might be greater among older patients who might also derive less benefit from oxaliplatin. We evaluated the association between adjuvant oxaliplatin-based chemotherapy and neurotoxicity outcomes in an elderly cohort of patients. PATIENTS AND METHODS: A population-based cohort of patients aged > 65 years with stage II and III colorectal cancer treated with adjuvant therapy in Ontario, Canada was identified using the Ontario Cancer Registry...

Ozone oxidation has been demonstrated to be an effective treatment process for the attenuation of trace organic compounds (TOrCs); however, predicting TOrC attenuation by ozone processes is challenging in wastewaters. Since ozone is rapidly consumed, determining the exposure times of ozone and hydroxyl radical proves to be difficult. As direct potable reuse schemes continue to gain traction, there is an increasing need for the development of real-time monitoring strategies for TOrC abatement in ozone oxidation processes...

Nitric oxide (NO) is generated from arginine and oxygen via NO synthase (NOS). Staphylococcus aureus NOS (saNOS) has previously been shown to affect virulence and resistance to exogenous oxidative stress, yet the exact mechanism is unknown. Herein, we report a previously-undescribed role of saNOS in S. aureus aerobic physiology. Specifically, aerobic S. aureus nos mutant cultures presented with elevated endogenous reactive oxygen species (ROS) and superoxide levels, as well as increased membrane potential, increased respiratory dehydrogenase activity, and slightly elevated oxygen consumption...

INTRODUCTION: To avoid potential cardiovascular collapse after Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), current guidelines recommend methodically deflating the balloon over 5 minutes to gradually reperfuse distal tissue beds. However, anecdotal evidence suggests that this approach may still result in unpredictable aortic flow rates and hemodynamic instability. We sought to characterize aortic flow dynamics following REBOA as the balloon is deflated in accordance with current practice guidelines...

REVIEW
Chuen Wai Lee, Robert J Cooper, Topun Austin
Over the past 15 years, functional near-infrared spectroscopy (fNIRS) has emerged as a powerful technology for studying the developing brain. Diffuse Optical Tomography (DOT) is an extension of fNIRS that combines hemodynamic information from dense optical sensor arrays over a wide field of view. Using image reconstruction techniques, DOT can provide images of the hemodynamic correlates to neural function that are comparable to those produced by functional MRI (fMRI). This review article explains the principles of DOT, and highlights the growing literature on the use of DOT in the study of healthy development of the infant brain, and the study of novel pathophysiology in infants with brain injury...

BACKGROUND: The value of formal physical therapy after total hip arthroplasty is unknown. With substantial changes that have occurred in surgical and anesthesia techniques, self-directed therapy may be efficacious in restoring function to patients undergoing total hip arthroplasty. METHODS: We conducted a single-center, randomized trial of 120 patients undergoing primary, unilateral total hip arthroplasty who were eligible for direct home discharge. The experimental group followed a self-directed home exercise program for 10 weeks...

Hematopoietic stem cell (HSC) transplantation and adoptive transfer immunotherapy are effective in treating blood cancers and post-transplant infections, but low circulating cell numbers in patients and donors is oftentimes a limiting factor. We postulate that a single exercise bout will increase the yield of patient and donor-derived HSC's and cytotoxic lymphocytes to improve this form of treatment for cancer patients.

The hypothalamic-pituitary-gonadal (HPG) axis is a key biological system required for reproduction and associated sexual behaviors to occur. In the avian reproductive model of the rock dove (Columba livia), we characterized the transcript community of each tissue of the HPG axis in both sexes, thereby significantly expanding our mechanistic insight into HPG activity. We report greater sex-biased differential expression in the pituitary as compared to the hypothalamus, with multiple genes more highly expressed in the male pituitary being related to secretory function, and multiple genes more highly expressed in the female pituitary being related to reproduction, growth, and development...
