PURPOSE: Hypertension in pregnancy has been associated with decreased future risk of breast cancer in many but not all studies. In the Marin Women's Study, pregnancy-induced hypertension was shown to interact with the T allele of a functional IGF1R gene variant, rs2016347, to result in lower breast density, as well as decreased breast cancer risk. Our objective was to explore these findings in a larger sample of women from the California Teachers Study (CTS). METHODS: The CTS cohort consists of over 130,000 female educators...

In this investigation, we prepare a self-healable polyelectrolyte film via crosslinking the cationically charged chitosan (Cts) with anionically modified bacterial cellulose (BC), which is a green source of nano-filler. This polyelectrolyte film is able to show dynamic self-healing activity at physiological pH condition via adapting ionic interaction, a state of non-covalent bond. BC was prepared using Glucanoacetobacter xylinus (MTCC7795) bacteria and after that its surface was modified with anionic poly(acrylic acid) using "grafting from" technique...

Proton range random and systematic uncertainties are the major factors undermining the advantages of proton therapy, namely, a sharp dose falloff and a better dose conformality for lower doses in normal tissues. The influence of CT artifacts such as beam hardening or scatter can easily be understood and estimated due to their large-scale effects on the CT image, like cupping and streaks. In comparison, the effects of weakly-correlated stochastic noise are more insidious and less attention is drawn on them partly due to the common belief that they only contribute to proton range uncertainties and not to systematic errors thanks to some averaging effects...

Multinary copper-based metal sulfide (Cu-M-S) nanocrystals (NCs) usually have high absorption coefficients and near-optimum direct band gaps, which have been considered as novel photo-absorption materials for quantum dot-sensitized solar cells (QDSCs) and hole-transport materials for perovskite solar cells (PSCs). However, the formation and phase transformation mechanisms of Cu-M-S NCs during the solution-based preparing approaches are complicated. Herein, Cu-M-S NCs, including Cu2ZnSnS4 (CZTS), Cu2SnS3 (CTS), CuInS2 (CIS), and CuSbS2 (CAS), have been synthesized through solution-based hot-injection methods...

Unambiguous investigation of condensed tannin (CT) structure-activity relationships in biological systems requires well-characterized, high-purity CTs. Sephadex LH-20 and Toyopearl HW-50F resins were compared for separating CTs from acetone/water extracts and column fractions analyzed for flavan-3-ol subunits, mean degree of polymerization (mDP) and purity. Toyopearl HW-50F generated fractions with higher mDP values and better separation of procyanidins (PC) and prodelphinidins (PD) but required a pre-purification step, more time for large scale purifications and gave poorer recoveries...

Peripheral immunity plays a key role in maintaining homeostasis and conferring crucial neuroprotective effects on the injured nervous system, while at the same time may contribute to increased vulnerability to neuropathic pain. Little is known about the reciprocal relationship between entrapment neuropathy and peripheral immunity. This study investigated immune profile in patients with carpal tunnel syndrome (CTS), the most prevalent entrapment neuropathy. All patients exhibited neurophysiological abnormalities in the median nerve, with the majority reporting neuropathic pain symptoms...

BACKGROUND: Radiation exposure is the reason for the decreased utilization of computed tomography (CT) in pediatric centers (PCs). We sought to compare the radiation dose exposure of CT imaging performed at outside hospitals (OH) versus PC in pediatric patients with acute appendicitis (AA). MATERIAL AND METHODS: A retrospective review of all patients managed at our PC for AA from January 2011 to March 2016 was performed. Patients who had CT imaging for AA at OH were compared to those who underwent CT for appendicitis at our PC...

Importance: Research in facial aging has focused on soft-tissue changes rather than bony changes despite evidence of the importance of underlying bony structural changes. Research has also been limited by comparing different patients in separate age groups rather than the same patients over time. Objective: To longitudinally document patterns of change in the facial skeleton and determine a consistent methodology for measuring these changes. Design, Setting, and Participants: Case series study of university hospital system records using facial computed tomographic (CT) images timed at least 8 years apart in adults initially aged 40 to 55 years with no history of facial surgery who required repeated facial imaging that included the entire midface and cranium...

BACKGROUND: The effectiveness of 14-French (14F) pigtail catheters (PCs) compared to 32-40F chest tubes (CTs) in patients with traumatic hemothorax (HTX) and hemopneumothorax (HPTX) is becoming more well known but still lacking. The aim of our study was to analyze our cumulative experience and outcomes with PCs in patients with traumatic HTX/HPTX. We hypothesized that PCs would be as effective as CTs. METHODS: Using our PC database, we analyzed all trauma patients who required chest drainage for HTX/HPTX from 2008 to 2014...

BACKGROUND AND PURPOSE: Whether changes in leisure-time physical activity (LTPA) over time are associated with lower risk of stroke is not well established. We examined the association between changes in self-reported LTPA 10 years apart, with risk of incident stroke in the CTS (California Teachers Study). We hypothesized that the risk of stroke would be lowest among those who remained active. METHODS: Sixty-one thousand two hundred and fifty-six CTS participants reported LTPA at 2 intensity levels (moderate and strenuous activity) at 2 time points (baseline 1995-96; 10-year follow-up 2005-2006)...

Importance: Parathyroid 4-dimensional computed tomographic scans (4D-CTs) have emerged as an accurate and cost-effective initial localization study for patients with primary hyperparathyroidism. However, potential limitations and factors affecting the accuracy of preoperative 4D-CTs remain poorly defined. Objectives: To characterize factors associated with missed parathyroid lesions on preoperative 4D-CTs and to investigate patterns of commonly observed errors. Design, Setting, and Participants: A prospectively accrued patient database was analyzed from September 1, 2011, through October 31, 2016...

Cor triatriatum sinistrum (CTS) is a congenital anomaly where the left atrium is divided into two compartments by a fibromuscular membrane. This report aims to add to the literature on a rare cardiac condition that can cause neurological morbidity. We report a case of a 19-year-old female with an infarct in the right middle cerebral artery (MCA) territory initially maintained on aspirin. Eighteen months later, she had recurrence of weakness, for which repeat transthoracic echocardiography (TTE) and re-evaluation of the first TTE demonstrated a hyperechoic membrane spanning the width of the left atrium, clinching the diagnosis of CTS...

PURPOSE: Carpal tunnel syndrome (CTS) has a high incidence in diabetic patients, with a reported incidence up to 21%. In severe cases of CTS, patients may undergo carpal tunnel release (CTR) surgery, which involves the risk of infection and other complications. To decrease the risk of infection, some physicians provide prophylactic antibiotics. Our study examines the effects of prophylactic antibiotic use, especially in a high-risk, diabetic population. METHODS: A total of 469 CTR surgeries performed by plastic surgery specialists were reviewed for diabetic status at the time of surgery and perioperative antibiotic use...
