#1
Zhang Jiechen, Hou Wei, Feng Suying, Chen Xiangsheng, Wang Hongwei
It is generally recognized that Caucasians and Asians have different skin aging features. The aim of this study was to develop a facial wrinkle grading scale for Chinese women. Standard photographs were taken of 242 Chinese women. Six sets of 0 to 9 wrinkle scales with reference photographs and descriptions were selected, including grading scales for resting and hyperkinetic crow's feet, frontalis lines, glabellar frown lines, and nasolabial folds. To identify the scale by objective quantitative measurement, skin surface measurements from the Visioscan(®) VC98 were used...

Since arsenic trioxide was first approved as the front line therapy for acute promyelocytic leukemia 25 years ago, its anti-cancer properties for various malignancies have been under intense investigation. However, the clinical successes of arsenic trioxide in treating hematological cancers have not been translated to solid cancers. This is due to arsenic's rapid clearance by the body's immune system before reaching the tumor site. Several attempts have henceforth been made to increase its bioavailability toward solid cancers without increasing its dosage albeit without much success...

Thyroid hormone (T3) induces liver preconditioning (PC) against ischemia-reperfusion (IR), a response energetically supported by AMP-activated protein kinase (AMPK) upregulation. The aim of this work is to evaluate the influence of T3 on IR-induced liver NLRP3 inflammasome activation and the relevance of AMPK activity on liver injury by the use of the AMPK inhibitor compound C (CC). Male Sprague-Dawley rats were given 0.1mgT3/kg (time zero) and 10mg CC/kg (time zero and 24h) or the respective vehicles, and subjected to 1h ischemia-20h reperfusion 48h after hormone treatment...

We have recently demonstrated that in a rat model of chemotherapy-induced peripheral neuropathy (CIPN), there is a significant decrease in the duration of the depolarization-evoked Ca(2+) transient in small diameter, IB4+, and capsaicin-responsive neurons innervating the glabrous skin of the hindpaw. This change was specific to the transient duration and significantly smaller if not undetectable in neurons innervating the dorsal skin of the hindpaw or the skin of the inner thigh. Given the importance of mitochondria in intracellular Ca(2+) regulation and the findings of chemotherapy-associated increase in mitotoxicity along the sensory neuron axons, we hypothesized that CIPN is due to both increases and decreases in mitochondria function, with changes manifest in distinct subpopulations of afferents...

REVIEW
Jenna R Krall, Matthew J Strickland
PURPOSE OF REVIEW: Estimating health effects associated with source-specific exposure is important for better understanding how pollution impacts health and for developing policies to better protect public health. Although epidemiologic studies of sources can be informative, these studies are challenging to conduct because source-specific exposures (e.g., particulate matter from vehicles) often are not directly observed and must be estimated. We reviewed recent studies that estimated associations between pollution sources and health to identify methodological developments designed to address important challenges...

Quyen Thu Bui, Ji Hye Im, Sung Baek Jeong, Young-Mi Kim, Sung Chul Lim, Bumseok Kim, Keon Wook Kang
We previously demonstrated that tamoxifen (TAM)-resistant human breast cancer (TAMR-MCF-7) cells showed increased expression of mesenchymal marker proteins compared to the parent MCF-7 cells. Notch is functionally important in the promotion of epithelial-mesenchymal transition (EMT) during both development and tumor progression. Notch1 and Notch4 have been reported as prognostic markers in human breast cancer. Here, we indicated that Notch4, but not Notch1, plays a critical role in the regulation of EMT signaling in TAMR-MCF-7 cells...

Migraine is a disabling brain disorder involving abnormal trigeminovascular activation and sensitization. Fasting or skipping meals is considered a migraine trigger and altered fasting glucose and insulin levels have been observed in migraineurs. Therefore peptides involved in appetite and glucose regulation including insulin, glucagon and leptin could potentially influence migraine neurobiology. We aimed to determine the effect of insulin (10U·kg(-1)), glucagon (100μg·200μl(-1)) and leptin (0.3, 1 and 3mg·kg(-1)) signaling on trigeminovascular nociceptive processing at the level of the trigeminocervical-complex and hypothalamus...

OBJECTIVE: Advanced Automatic Crash Notification (AACN) uses vehicle telemetry data to predict risk of serious injury among motor vehicle crash occupants and can thus improve the accuracy with which injured children are triaged by first responders. To better define serious injury for AACN systems (which typically use Abbreviated Injury Scale [AIS] metrics), an age-specific approach evaluating severity, time sensitivity (TS), and predictability of injury has been developed. This study outlines the development of the TS score...

Explosives residues in soils may be a useful source of evidence following the detonation of an improvised explosive device (IED), such as a vehicle-borne IED. Soil samples collected from the vicinity of an explosion scene will often be stored for some time prior to analysis, yet explosives residues in soil samples are susceptible to rapid degradation or transformation. Although some research has assessed the use of different storage temperatures with a view to reducing explosives' degradation over time, further research examining the degradation of explosives in soil when stored under a variety of storage conditions is crucial to determine the optimal sample collection and storage procedures for soil containing explosives residues...

BACKGROUND: A commonly used measure to reflect the intake of the long-chain omega-3 fatty acids EPA and DHA is the omega-3 index, defined as the sum of EPA + DHA as % of total fatty acids in erythrocyte membrane. When the omega-3 index changes it follows that the relative fractions of other fatty acids in the membrane are also changed. In the present study, increasing doses of a preparation of omega-3 rich phospholipids extracted from krill oil were administered orally to non-human primates for 12 weeks and the time course of EPA, DHA and 22 other fatty acids in erythrocytes was determined bi-weekly during treatment and for 8 weeks after cessation of treatment...
