Effect of modified radical mastectomy combined with latissimus dorsi musculocutaneous flap breast reconstruction on patients' psychology and quality of life.

Background: Breast carcinoma (BC) is a commonly seen malignancy in women. Although traditional radical mastectomy can improve the survival of patients, it can cause breast loss and chest wall deformities, which seriously affects the daily life of patients and causes anxiety and depression. The purpose of this research project is to investigate the effect of breast reconstruction with latissimus dorsi myocutaneous flap (LDMF) after nipple- and areola-sparing modified radical mastectomy (MRM) on the psychological mood and quality of life (QoL) of patients with stage I BC.

Effect of Bonding Strength on Electromigration Failure in Cu-Cu Bumps.

In microelectronic packaging technology for three-dimensional integrated circuits (3D ICs), Cu-to-Cu direct bonding appears to be the solution to solve the problems of Joule heating and electromigration (EM) in solder microbumps under 10 μm in diameter. However, EM will occur in Cu-Cu bumps when the current density is over 106 A/cm2. The surface, grain boundary, and the interface between the Cu and TiW adhesion layer are the three major diffusion paths in EM tests, and which one may lead to early failure is of interest.

Failure Mechanisms of Cu-Cu Bumps under Thermal Cycling.

The failure mechanisms of Cu-Cu bumps under thermal cycling test (TCT) were investigated. The resistance change of Cu-Cu bumps in chip corners was less than 20% after 1000 thermal cycles. Many cracks were found at the center of the bonding interface, assumed to be a result of weak grain boundaries.

Palladium-catalyzed dearomative allylation of indoles with cyclopropyl acetylenes: access to indolenine derivatives.

A palladium-catalyzed redox-neutral allylic alkylation of indoles with cyclopropyl acetylenes has been disclosed. Various 1,3-diene indolenine framework bearing a quaternary stereocenter at the C3 position were synthesized straightforwardly in good to excellent yields with high regio- and stereoselectivities. The reaction could be further expanded to the dearomatization of naphthols to synthesize functionalized cyclohexadienones with 1,3-diene motifs.

Tensile Properties of <111>-Oriented Nanotwinned Cu with Different Columnar Grain Structures.

We performed tensile tests on highly <111>-oriented nanotwinned copper (nt-Cu) foils with different columnar grain structures. For a systematic study, we altered the microstructure of the foils by tuning the electroplating electrolyte and annealing temperatures under a nitrogen atmosphere. The results show that the yield strength ranges from 300 to 700 MPa, and elongation spans from 5% to 25%.

Tensile Properties and Thermal Stability of Unidirectionally <111>-Oriented Nanotwinned and <110>-Oriented Microtwinned Copper.

Tensile tests on two kinds of electroplated copper foils with twins before and after annealing were performed. One electroplating parameter results in a microstructure of <110>-oriented microtwinned Cu (mt-Cu), and the other is <111>-oriented nanotwinned Cu (nt-Cu). The latter shows higher thermal stability than the former after annealing.

Enhanced Photovoltage Response of Hematite-X-Ferrite Interfaces (X = Cr, Mn, Co, or Ni).

High-fluorescent p-X-ferrites (XFeO; XFO; X = Fe, Cr, Mn, Co, or Ni) embedded in n-hematite (FeO) surfaces were successfully fabricated via a facile bio-approach using Shewanella oneidensis MR-1. The results revealed that the X ions with high/low work functions modify the unpaired spin Fe-O orbitals in the XFeO lattices to become localized paired spin orbitals at the bottom of conduction band, separating the photovoltage response signals (73.36~455.

Spinal TRPC6 channels contributes to morphine-induced antinociceptive tolerance and hyperalgesia in rats.

The chronic administration of opioids results in the development of morphine analgesic tolerance and withdrawl-induced hyperalgesia, which limits their clinical utility in pain treatment. However, the cellular mechanisms underlying opioid-induced tolerance and hyperalgesia are not fully understood. The transient receptor potential canonical channel TRPC6 is important for brain development and function, as it regulates cytosolic, endoplasmic reticulum, and mitochondrial Ca levels in neural cells.
