PURPOSE: Chemotherapy-induced alopecia (CIA) is a distressing side effect for women with breast cancer undergoing chemotherapy. Scalp cooling is a method aiming to prevent CIA, but its efficacy is not well defined. Randomized trials until recently and at the time this trial was designed have been lacking. METHODS: Patients undergoing (neo)adjuvant chemotherapy for early breast cancer (EBC) were randomized to scalp cooling (CAP) or observation (NoCAP). All patients received 18-24 weeks of anthracycline- and/or taxane-based chemotherapy...

Liquid oceans and ice caps, along with ice crusts, have long been considered defining features of the Earth, but space missions and observations have shown that they are in fact common features among many of the solar system's outer planets and their satellites. Interactions with rock-forming materials have produced saline oceans not dissimilar in many respects to those on Earth, where mineral precipitation within frozen seawater plays a significant role in both determining global properties and regulating the environment in which a complex ecosystem of extremophiles exists...

This study presents a novel, thermoelectric cryotherapy cap that aims to provide effective and controlled scalp cooling to prevent hair loss for chemotherapy patients. The cap's design consists of multiple thermoelectric coolers (TECs) evenly spaced and bonded to a soft thermal interface material, tightly fitted to a patient's head. A numerical model is developed to assess the performance of alternative cap designs in relation to their ability to achieve hair follicle hypothermia. Under ideal conditions, 26...

Transient infrared emissions of gold nanorods capped with various materials (AuNR@X, X = CTAB, PSS, mPEG, and SiO2 ) upon ∼70-μs pulsed 1064 nm excitation of their longitudinal surface plasmonic bands were collected with a time-resolved step-scan Fourier-transform spectrometer. Comparing the observed emission contours with the blackbody radiation spectra revealed that parts of the additional emission intensity at low wavenumbers (1300-1000 cm-1 ) were attributed to the vibrational modes of the capping materials, suggesting that the photothermal energy of AuNRs can be thermalized not only via blackbody radiation but also via radiative and nonradiative processes of the capping materials...

Palaeoclimate reconstructions of periods with warm climates and high atmospheric CO2 concentrations are crucial for developing better projections of future climate change. Deep-ocean1,2 and high-latitude3 palaeotemperature proxies demonstrate that the Eocene epoch (56 to 34 million years ago) encompasses the warmest interval of the past 66 million years, followed by cooling towards the eventual establishment of ice caps on Antarctica. Eocene polar warmth is well established, so the main obstacle in quantifying the evolution of key climate parameters, such as global average temperature change and its polar amplification, is the lack of continuous high-quality tropical temperature reconstructions...

The new cardiopulmonary resuscitation (CPR) guideline emphasize the importance of chest compression, which was considered as the first step to CPR. The duration for CPR is usually limited to 30 minutes. With the development of new technology and evidence-based medicine, the success of extra longtime CPR has become possible, which is of great significance to some patients with cardiac arrest (CA), but the time limit has not been determined. On February 23rd in 2016, a 76-year-old female patient with respiratory and cardiac arrest who was on the third day after transurethral resection of bladder tumor (TUR-BT) was admitted to the intensive care unit of the General Hospital of Fushun Mining Bureau...

Current analytical models for sessile droplet evaporation do not consider the nonuniform temperature field within the droplet and can overpredict the evaporation by 20%. This deviation can be attributed to a significant temperature drop due to the release of the latent heat of evaporation along the air-liquid interface. We report, for the first time, an analytical solution of the sessile droplet evaporation coupled with this interfacial cooling effect. The two-way coupling model of the quasi-steady thermal diffusion within the droplet and the quasi-steady diffusion-controlled droplet evaporation is conveniently solved in the toroidal coordinate system by applying the method of separation of variables...

Chemotherapy-induced alopecia is a common and distressing adverse effect of many types of chemotherapy. Scalp cooling has been used since the 1970s for prevention of chemotherapy-induced alopecia; however, most data regarding this treatment modality are retrospective in nature, and use in the United States has been limited by safety concerns, specifically the potential for scalp metastases. Two prospective studies of scalp-cooling systems performed in the United States were published within the last year and add evidence supporting the efficacy and safety of scalp cooling in preventing chemotherapy-induced alopecia in patients receiving chemotherapy for solid tumor malignancies...

INTRODUCTION: Cutaneous warts are common skin lesions, caused by human papillomavirus. For years, liquid nitrogen is the cryogen of choice for wart treatment. Alternatively, several cryogenic devices for home treatment are commercially available. The present trial assessed efficacy and safety of a novel nitrous oxide-based cryogenic device for home use (EndWarts Freeze® in Europe, Compound W® Nitro-Freeze in the USA). METHODS: This investigator-blinded, controlled, randomized study compared the nitrous oxide device (test product) with a dimethylether propane-based product (Wartner® ; comparator 1)...

Herein, for the first time, we applied the metal-metal-bond-energy factor to the evolution of a porous Se-Te alloy. The porous Se-Te material has been prepared from the constituents' elemental states, through only a heating-cooling process in silicone oil without the use of any reagent, surfactant, or capping agent. Surprisingly, the reaction occurred at a much lower temperature (240 °C) than the mp (450 °C) of Te0 . The reaction's nucleation and growth by means of varied bond energy have been clarified for the first time...

PURPOSE: To study the relation between irretrievable abutment healing caps (AHCs), temperature, and the torque required to remove the AHCs from implants. MATERIALS AND METHODS: Twenty implants, 13 mm long and 4.2 mm in diameter, were inserted into four acrylic boxes and covered with acrylic resin. An AHC was screwed into each implant, using a 30 N/cm torque. The acrylic blocks were placed in a 37°C water bath, and subsequently, a block was removed from the bath, the AHCs were cooled, and the torque needed to release each AHC from the implant was measured using a torque wrench...

We propose two approaches-hot-embossing and dielectric-heating nanoimprinting methods-for low-cost and rapid fabrication of periodic nanostructures. Each nanofabrication process for the imprinted plastic nanostructures is completed within several seconds without the use of release agents and epoxy. Low-cost, large-area, and highly sensitive aluminum nanostructures on A4 size plastic films are fabricated by evaporating aluminum film on hot-embossing nanostructures. The narrowest bandwidth of the Fano resonance is only 2...

The present protocol describes a unique approach that enables the collection of cardiac transudate (CT) from the isolated, saline-perfused rat heart. After isolation and retrograde perfusion of the heart according to the Langendorff technique, the heart is inverted into an upside-down position and is mechanically stabilized by a balloon catheter inserted into the left ventricle. Then, a thin latex cap - previously cast to match the average size of the rat heart - is placed over the epicardial surface. The outlet of the latex cap is connected to silicon tubing, with the distal opening 10 cm below the base level of the heart, creating slight suction...

The main challenge in disk laser design is the realization of efficient heat removal from the pumped area by optimizing the heat spreader design and the water impingement cooling. This generally requires the calculation of the temperature distribution in the disk by numerically solving the heat conduction equation using finite element algorithms. We have developed a simple method to calculate disk temperature profiles that is based on analytically solving the heat conduction equation in Hankel transform space...
